After suppressing the internal tribulation a little, the Northern Yin Xuan immediately began to act.

I saw him stretch out his hand, and from the ancestral root of the divine tree, endless clear light suddenly emerged. This innumerable clear light was attracted by the drunken capital, draped over his body, and wrapped him in pieces.

With the help of these clear lights, the internal tribulation on the body of the Northern Yin Yudu was like ice melting and snow melting, and the black qi in his heart melted away.

Seeing that the last bit of black qi entrenched in his heart was about to be destroyed, at this moment, there was a sudden terrible roar, as if countless demons and monsters were shouting. This strange roar actually penetrated the barrier of the Divine Tree and was transmitted to the side of the Six Roulette Wheels. This strange roaring demon sound immediately aroused the black qi that was about to be wiped out in the heart of the Northern Yin Sullen Capital.

The black qi that had been suppressed by Qingguang immediately began to struggle and churn when the strange howl came.

"It's not good!" Beiyin said secretly in his heart, this strange howl was also mixed with the sound of demons, and he was trying his best to disturb his mind. He knew that once his mind was in turmoil, these black qi would immediately start to fight back. If one is not careful, it is likely that he will fall into a situation from which he will never recover.

Originally, he was carrying out the robbery, and most of his mind had been involved. The suppression of the internal tribulation has used up the only remaining heart, and now there is a demonic sound and a strange roar to disturb the mind. He could only brace himself and resist the harassment of the demon sound, while suppressing the counterattack of the black qi.

On the other side, after the creation of the Ten Thousand Things Rune was cast, he retreated to the side, and Ling Yun was watching the state of the Northern Yin Capital together. In this internal tribulation, they outsiders can only do some auxiliary work, and if they want to really survive the internal tribulation, they must rely on Beiyin to survive by themselves.

"This time, the nephew should be able to survive the internal tribulation unharmed, right?"

"It's too early to say this at this point!" "Creation shook his head, not agreeing with Ling Yun's words, "I don't believe they will give up this opportunity!"

Sure enough, not long after the words of creation fell, suddenly a strange roaring demon voice came.

When Ling Yun heard this magic sound, he immediately began to feel upset and nauseated, and his expression was irritable. Barely suppressing the restless emotions in his heart, Ling Yun asked to Creation with difficulty, "What kind of voice is this, how can it be ......?"

"This is a mixture of the Divine Demon Sound and the Heavenly Demon Roar, it is their forte, if they are accidentally aroused by the Six Desires Yin Demon, the whole person will be greatly damaged!" "With a wave of his hand, a Yin Yang Ancestral Qi fell from the ancestral root of the Divine Tree, and after he sketched a few runes, he arranged it around his body.

Soon, the influence of the magic sound was much weakened. At this time, Ling Yun's expression improved.

"I can't completely block the magic sound with this arrangement, the god-shaking demon sound and the heavenly demon roar itself will not have any effect on the Northern Yin Spirit, but his side is in the midst of a catastrophe, and the effect of this magic sound on him is magnified thousands of times, which is very unfavorable to him!"

"Then what should I do?" Hearing what Zaohua said, Ling Yun immediately lifted his heart. Looking at the black qi churning in the heart of the Northern Yin Xuandu, he felt as if the next moment, those black qi were about to break through the Qingguang suppression, and the entire person of the Northern Yin Xuandu would be wrapped up and devoured.

Looking up at the six roulette wheels in mid-air, Creation said in a deep voice: "For today's plan, there is only one way!"

"What's the solution?"

"The two worlds are separated!" he spewed out a term that Ling Yun had never heard of.

"What do you mean by the separation between the two worlds?"

While waving his hand to arrange something, Creation explained to Ling Yun: "The so-called separation between the two worlds refers to the separation of different worlds from each other. This kind of separation can even block the connection between cause and effect! The Shaking God Demon Sound and the Heavenly Demon Roar are only the first song now, and they will become stronger and stronger later, and the forbidden law of the Northern Yin and Yu Capital cannot be stopped, so it needs to be blocked by the separation of the two realms. ”

"Of course, this kind of barrier can still be broken if it is studied. But if you want to break through the barrier between two different worlds, you need time to understand and calculate. In this way, it is enough to delay for a while, so that the Northern Yin Xuan will be successfully tribulated!"

"Is that so?" This method is indeed a good solution to the current situation, but one point is crucial, "If there is a separation between the two worlds, there is no second world to divide here?"

"No, there are!" Creation Hua's gaze fell on Ling Yun, "Your Cave Heaven!"

"Cave Heaven, that level is not enough, right?" Ling Yun was very skeptical that his Cave Heaven would be able to block the god-shaking demon sound and the heavenly demon roar that would become stronger and stronger. If you can't stop it, won't it be in vain?

"I have my own solution to this matter!" "Creation changed his technique, calculating something, and arranged it. Then, he said to Ling Yun, "You sit down first and meditate!"

"Oh!" Ling Yun sat down cross-legged as he spoke, collecting his mind and ignoring the faint sound of demons. In an instant, Ling Yun's mind fell into a state of tranquility, and all his thoughts dissipated.

At this time, Creation came to stand behind Ling Yun, stretched out his hand to play a complicated spell, and then pressed his hand on Ling Yun's back. Suddenly, countless Yin and Yang Ancestral Qi seemed to be returning to the sea and leaning towards Lingyun.

"This is ......" Feeling a majestic and vast power flowing in, about to enter the body, Ling Yun was hesitating, whether to let go, when the voice of creation came: "Open the cave and include all of this!"

When Ling Yun heard this, he immediately opened the blockade control of the cave sky, and swallowed all the gathered power into the cave heaven in his body.

As the Yin Yang Ancestral Qi continued to flow into the Cave Heaven, the Yin Yang Ancestral Qi was wrapped around the World Tree in the Cave Heaven. For these innate yin and yang ancestors, the World Tree did not refuse to come and absorbed them all. Thanks to the help of these innate Yin and Yang Ancestors, the World Tree began to evolve rapidly. And Ling Yun's natal cave heaven also began to expand its scope rapidly.

"Quickly release the cave heaven!" Just as Ling Yun was concentrating on absorbing the Innate Yin Yang Ancestral Qi released by the Divine Tree Ancestral Root, the sound of creation came again.

Ling Yun didn't delay at all, and immediately released the cave outside the sky. The cave sky in his body was exposed to the outside, and a thick spatial barrier encompassed the range where Ling Yun was sitting cross-legged. Subsequently, the cave barrier expanded outward, incorporating more and more places into the space.

At this moment, Creation cast a spell, and immediately countless roots broke through the air, piercing into Lingyun's cave sky, and intertwined with his World Tree roots.

Although the Divine Tree is the supreme treasure spirit root that supports the Netherworld, its essence is a cut below that of the World Tree. Although the World Tree used to support the Cave Heaven in Lingyun Cave Heaven was still only a seedling, it already possessed some of the essence of the World Tree. Thus, devouring the roots of the Nether Tree was effortless.

Nourished by this Nether Tree, the World Tree began to grow at a faster rate.

If the original growth rate is one, after being nourished by the Innate Yin and Yang Ancestor Qi, the growth rate of the World Tree is ten. And now, devouring the Nether God Tree, the growth rate of the World Tree has reached the level of hundreds or even thousands.

The more he swallowed, the faster the World Tree grew, and Ling Yun could even see the branches of the World Tree sprouting with the naked eye.

"Is there such a way?" Ling Yun watched as the World Tree devoured the roots of the Nether God Tree, and his heart was secretly surprised. Seeing this, his mind couldn't help but think of other places: "If I can use the World Tree to devour other innate spirit roots, can I also increase the growth speed of the World Tree?"

Ling Yun immediately gave up this thought: "This method may be a shortcut, but there may be some hidden dangers, forget it!" Retracting his thoughts, he began to concentrate on adjusting the changes in the cave.
