After laughing, Qin Ziling’s spiritual sense quickly contacted the fire dragon.

He is now a god, and the Fire Dragon has recovered a lot in recent days. It is still very easy to awaken the Fire Dragon now. However, the cost of asking the Fire Dragon to cast the Nine Dragons Divine Fire Cover is still relatively high.

Qin Ziling told Huolong about the confusion Xiao Qing encountered.

Huo Long was indeed well-informed and experienced, and he quickly explained: "You can think of human immortals as children who set up their own families and set up their own houses, while earthly immortals are equivalent to children who inherit the family business. Children who inherit the family business will naturally have someone in the family to teach them step by step, allowing them to inherit the family business step by step.

For the children who set up their own business and establish their own residence, once they leave home, they have to learn many things on their own and make their own way, and the family will provide them with very little help.

The rebirth and Dharmakaya realms of human immortals are only at the stage of stepping out of the home. Only when you reach the cave heaven realm can you be considered to have initially established your own home and established your own residence. This is because the cave heaven already means that the prototype of a small world has taken shape.

At this time, the human immortal has already begun to walk his own path, so to take this step, you need to prove that you have understood your own path, and then the heaven and earth will send down a heavenly tribulation. If you can get through it, you will be truly qualified to set up your own school and build your own palace."

"It turns out that the path of Qi Refining is the darling of this world! No wonder the path of Qi Refining has the most people, and is relatively the least dangerous." Qin Ziling had an epiphany after hearing this.

"So, if Xiao Qing wants to trigger the heavenly tribulation, not only does his skill have to meet the requirements, but he also needs to comprehend more of the true meaning of the cave heaven." The fire dragon continued.

"The Wuji Sect does not have any human immortals who have reached the Cave Heaven realm. If one wants to comprehend the true meaning of the Cave Heaven on one's own, it will probably take a very long time. Senior, do you have any way to give me some pointers?" Qin Ziling asked.

"My path is different from yours, so I can't directly teach you the true meaning of the cave heaven." The fire dragon replied.

Qin Ziling couldn't help but feel disappointed when he heard this.

"You really are sitting on a treasure mountain but don't know how to dig it out. Instead, you go to great lengths to ask me, a layman in martial arts." Seeing the disappointment on Qin Ziling's face, the fire dragon couldn't help but shook its big head.

"What do you mean by this, senior?" Qin Ziling's heart skipped a beat and he asked.

"What is a cave heaven? Isn't a cave heaven a small world? Don't you have a magic weapon of a cave heaven world in your hand? Its path is actually the path of you human immortals. It will continue to develop and become a small barrier, a small world, and even a great world.

It is your best teacher. Through it, you can constantly comprehend the formation, change, and development of the cave world, as well as construct various heavenly laws.

I have to say that you are a truly lucky person. You actually obtained the Earth Spirit Ring formed by the essence of the earth's energy, and obtained the natural Tiangang Formation formed by thirty-six Leixun boulders from the wind and thunder small barrier. Finally, you opened up a cave in the Earth Spirit Ring.

Your magic weapon is only in its infancy now. Once it develops, it will be a truly heaven-defying magic weapon! Of course, you can't become the world's top celebrity just by having great luck.

You have mastered the path of heaven, earth and man at such a young age, and have cultivated to this level. In addition to good luck, it also has a lot to do with your talent, perseverance, and cautiousness. "As he spoke, Huo Long couldn't help but sigh at Qin Ziling's luck and his talent and personality.

Qin Ziling didn't hear anything about Huo Long's later sighs. At this moment, the words Huo Long said earlier were still echoing in his mind.

It was like being hit hard!

"Senior, what you said is absolutely right. I really am sitting on a treasure mountain but don't know it!" After a long time, Qin Ziling calmed down and bowed deeply to the fire dragon.

…

"boom!"

The last ray of purple lightning surrounded by black flames struck down.

The sky is falling apart.

Magma gushed out and dust filled the sky.

After a long time, the last purple thunder of Nether Fire disappeared, and the calamity cloud disappeared with it.

The magma on the ground was still flowing out, and Ying Bao was nowhere to be found.

"Where is Ying Bao?" Xiao Qing's face changed drastically.

"Not dead yet!" Qin Ziling breathed a sigh of relief, flew forward, transformed into a golden dragon claw and probed directly into the depths of the magma.

Then the golden dragon claw grabbed Ying Bao, who had lost his wings, had two broken legs, and whose entire body seemed to be falling apart.

"This..." Xiao Qing took a deep breath and said, "That was close!"

"Yes, they were just a little bit away from death. Fortunately, the fire dragon refined them with fire first, and prepared the 'Xuanming Pill' specifically for them. Otherwise, even if I let them soak in a blood pool of the True Immortal level every day, they would not be able to survive this calamity!" Qin Ziling took a deep breath when he saw this, and at the same time he was deeply impressed by how difficult it was for zombies to survive the calamity.

As he spoke, Qin Ziling had already moved Ying Bao into the cave world and let him soak in the pool of blood.

In the pool of blood, all four of them were there.

At this moment, they were greedily absorbing the energy from the blood pool, emitting an extremely terrifying aura.

This aura is so powerful that it is not inferior to that of Biteng and others.

Zombies are dead creatures and should not exist in this world.

Therefore, it is more difficult for zombies to cultivate and become immortals than for other races, and once they cultivate and become immortals, their strength will be even stronger.

"Let's go, I will take you to comprehend the mysteries of the cave realm!" Qin Ziling said after moving Ying Bao into the cave world.

"You're going to help me comprehend?" Xiao Qing looked puzzled.

Qin Ziling smiled meaningfully at Xiao Qing, and Xiao Qing inexplicably had a bad feeling.

Ten days later, in the cave world, at the source of the Longyuan River, halfway up the Qianlong Mountain, in a warmly decorated courtyard room, Xiao Qing broke free from Qin Ziling's arms with a slightly blushing face and stood up.

"Wouldn't you like to meditate on it for a few more days?" Qin Ziling stood up and hugged Xiao Qing from behind.

Xiao Qing took a deep breath, suppressed his flustered mood, and said calmly, "It's almost done."

During these ten days, Qin Ziling used the method of blending his soul with Xiao Qing to allow her to personally experience the changes and true meaning of the cave.

Just as Huolong said, Qin Ziling was in a treasure trove but didn't know it.

In just ten days, Xiao Qing, whose skills had already reached the peak, gained a deeper understanding of the true meaning of the cave heaven.

"Okay!" Qin Ziling said with lingering feeling.

"Xia Yan will be there soon, you go find her. I'll meditate for a while and get to grips with it. I should be able to sense the heavenly tribulation soon!" Xiao Qing couldn't help but roll her eyes at Qin Ziling when she saw that he seemed to be unsatisfied.

"Don't think too much, I just want to help you comprehend it for a few more days!" Qin Ziling said.

Xiao Qing did not answer Qin Ziling, but just rolled his eyes at him.

Qin Ziling touched his nose awkwardly and said, "Isn't that to help you comprehend the true meaning of the cave heaven more deeply? When our spirits and souls are truly integrated, what we comprehend will be the most real."

"You still say that!" Xiao Qing's pretty face turned slightly red when she heard that, and she couldn't help but glare at her.

"Haha!" Qin Ziling couldn't help but laugh triumphantly when he saw this.

Seeing Qin Ziling's smug look, Xiao Qing felt helpless.

However, thinking back to the time when their souls were blending together, that kind of infatuation and ecstasy, he couldn't help but feel a little flustered.

…

One month later.

The Wuji Fairy Island is once again shrouded in calamity clouds.

This time, the aura emanating from the center of the vortex of the tribulation cloud was even more terrifying than when the four of them were undergoing the tribulation.

However, during this period of time, Qin Ziling has made improvements to the Small Tiangang Disha Formation and the Four Symbols Zhuxian Formation, so he doesn't have to worry about not being able to block the changes in the energy of heaven and earth.
Of course, for this purpose, many resources that Qin Ziling obtained from the Turbulent Abyss flowed out like water, and he even urgently transferred some resources from the Green Water Palace, the Dragon Whale Palace, the Silver Dragon Palace and the Ten Thousand Whales Valley.

Under the calamity clouds, Xiao Qing was wearing Green Dragon Armor, holding a Green Dragon Spear, standing upright, like an ancient female war god, indescribably heroic.

In the distance, on a mountain peak, Qin Ziling looked at Xiao Qing with a somewhat nervous expression.

He wasn't nervous when he himself was going through the tribulation, but he didn't know why he always felt frightened when Xiao Qing was going through the tribulation.

"You're nervous. That's not like you."

The voice of a fire dragon suddenly rang in Qin Ziling's mind.

"Senior, why did you wake up by yourself?"

"The aura of this heavenly tribulation is a little different. It woke me up."

"Will Xiao Qing be in danger?" Qin Ziling asked with a nervous heart.

"How can there be no danger in going through the Heavenly Tribulation?" Fire Dragon asked back, and then said: "But you don't have to be too nervous. Xiao Qing's Qi and blood are very strong and pure, and her body is also very strong. As long as the Heavenly Tribulation does not exceed fifty-seven, she should be able to withstand it. If it exceeds fifty-seven, then it depends on luck."

"Fifty-seven!" Qin Ziling's pupils shrank slightly.

Generally speaking, the Rebirth Realm has twenty-nine heavenly tribulations and eighteen heavenly thunders; the Dharmakaya Realm has forty-nine heavenly tribulations and thirty-six heavenly thunders; and the Cave Heaven Tribulation Realm has sixty-nine heavenly tribulations and fifty-four heavenly thunders.

The heavenly tribulation in the realm of barrier is seventy-nine heavenly tribulations, sixty-three heavenly thunders.

The difference of nine heavenly thunders between fifty-four heavenly thunders and sixty-three heavenly thunders just corresponds to the nine grades of the cave heaven realm.

Therefore, the fifty-seven heavenly thunders may seem to have only three more thunders than the normal cave heaven tribulation, and the number is very small, but in fact, the power is almost comparable to the attack of an ordinary third-grade cave heaven realm immortal.

This also means that once Xiao Qing can withstand fifty-seven heavenly thunders and stabilize his realm for a period of time, he will definitely be able to rival a third-grade True Immortal.

"Based on my experience, the power of this heavenly calamity should not exceed fifty-seven." Fire Dragon said immediately.

"Yeah!" Qin Ziling felt a little relieved.

“Boom!”

A dark purple lightning struck down from the vortex.

The purple thunder of destruction!

Xiao Qing's cave heaven tribulation finally came.

The fire dragon has lived for who knows how many long years. Although its strength has dropped drastically, its eyesight is still there.

He said that Xiao Qing's heavenly tribulation would not exceed fifty-seven. Sure enough, Xiao Qing's heavenly tribulation finally stopped at fifty-seven, and Xiao Qing also passed through the cave heaven tribulation without any danger.

As soon as Xiao Qing survived the heavenly tribulation, a cave appeared behind her.

There is a sapling growing in the cave, exuding vitality, and there is a small green dragon coiled around the sapling.

This cave gives people a very mysterious feeling.

It seemed unreal, like a mirage floating behind her, but at the same time it gave people a real feeling. The vitality and the heavy pressure brought by the cave were all real, as if they could be touched.

Perhaps it would be more accurate to say that it is both real and illusory.

It seems to belong to this world, but also seems to transcend this world and exist in another subspace.

“This is the cave heaven realm!”

Although Qin Ziling realized the true meaning of the cave world through the cave world in his Qiankun Ring, seeing Xiao Qing evolve her own cave world with her physical body, qi, blood and strength, that kind of real and illusory vision, that kind of belonging to this world and yet transcending this world, still gave him a very shocking and novel feeling.

"This is the cave world! The newly formed cave world will be relatively small, between illusion and reality, but as the strength continues to grow, the cave world will become bigger and bigger, more and more real, and eventually become a real cave world." The fire dragon looked at the cave world that appeared behind Xiao Qing's head, and his one eye revealed a complex look of reminiscence.

"Now I understand why there is a legend that when strong people in ancient times died, their bodies would turn into mountains and rivers!" Qin Ziling said.

"Dust to dust, ashes to ashes! No matter whether they are earthly immortals or human immortals, they all come from this world where they were born and raised. If they cannot jump out of this world, they will eventually return to this world." said the fire dragon.

"What will it be like if I jump out of this world?" Qin Ziling suddenly felt a little yearning.

But soon, Qin Ziling put away his wandering thoughts.

Jumping out of this world is too far away for him now.

When Qin Ziling put away his wandering thoughts, Xiao Qing also put away her vision of the cave.

She grabbed a handful of Wuchen Yuandan and swallowed it, then sat cross-legged, which made Qin Ziling's heart beat wildly.

It's true that he has a wealthy family.

Not long ago, one hundred and fifty Wuchen Yuandan were refined at one time, and there are still about a hundred left.

But he couldn't resist Xiao Qing's way of eating by just grabbing a handful and stuffing it directly into his mouth!

"The higher your cultivation level, the more resources you need, so you should understand my situation now! You are still too weak and you can't support me at all!" The fire dragon seemed to sense Qin Ziling's change of mood and sighed.

Qin Ziling remained silent after hearing this, feeling a heavy weight on his shoulders.

…

Another month passed.

On this day, Qin Ziling faced his true immortal tribulation.

His true immortal tribulation consisted of fifty-eight purple thunders, but he escaped without any danger.

Once he had passed the True Immortal Tribulation, Qin Ziling's strength suddenly skyrocketed, and he could rival a fourth-grade True Immortal just by refining Qi.

In terms of martial arts, he is now in the late stage of the Dharmakaya realm. However, Qin Ziling has a solid foundation. If he wants to reach the peak of the late stage of the Dharmakaya realm and trigger the heavenly tribulation, it will take some time to accumulate.

Not long after Qin Ziling passed the True Immortal Tribulation, Xia Yan also passed the Cave Heaven Tribulation.

Martial arts emphasizes bravery and perseverance. With the help of Wuchen Yuandan and the fusion of Xia Yan's soul with Qin Ziling, she personally realized the true meaning of the cave heaven, so she quickly sensed the heavenly tribulation and passed it.

Xia Yan’s cave heaven tribulation was a normal sixty-nine heaven tribulation.

Xia Yan also practiced the Qinglong Xuanmu Gong, so the cave vision she formed was the same as Xiao Qing's, but it looked much smaller than Xiao Qing's.

Zheng Xinghan and other immortals were not able to sense the cave heaven tribulation so quickly, but with the guidance of Xiao Qing and Xia Yan, everyone made rapid progress.

On the contrary, Jian Bailou and others took the path of Qi Refining. Even with the help of Wuchen Immortal Pill, they still couldn't make progress as bravely as Zheng Xinghan and others, and it would take them a long time to sense the True Immortal Tribulation.

After Xia Yan survived the cave heaven tribulation, Wuji Fairy Island lifted the blockade.

The sea area around Wuji Fairy Island returned to normal, as if nothing had happened.

No one knew that in just less than half a year, the strength of Wuji Fairy Island had undergone earth-shaking changes.

Now in the entire Pingyu Mountain blessed land, Wuji Fairy Island has become the most powerful existence.
