When Qin Yu arrived at Tianbi Valley, it was almost evening, and there was no one in sight at the mouth of the valley. Fortunately, the stone wall next to it is engraved with the three big characters "Tianbi Valley", but you don't have to worry about finding the wrong place.

Qin Yu walked along the path at the mouth of the valley, and after rounding a corner, he found that there was already a wide valley in front of him. Deep in the valley stands a two-storey white jade altar with a bonfire burning under it, and the rising light of the fire illuminates the world clearly. The cliff behind the stone altar is as smooth as a mirror, and there are more than 3,000 large and small Yanwen engraved on it.

"This must be the Heavenly Wall!"

Qin Yu went through a lot of hardships and finally saw the heavenly wall of his dreams, and his heart was full of mixed feelings for a while. He ascended the stone altar and found that there were still many Xuanyuan disciples on the altar who had attained enlightenment here. There was also a group of teenage boys and girls huddled in the corner, looking listless, and had no intention of deducing Yanwen at all.

After Qin Yu looked around, he casually found an open space and sat down. He looked up at the wall of heaven and slowly threw his divine sense into it.

As soon as the divine consciousness sank steeply into the stone wall, the Yanwen on the wall began to flow and change illusions non-stop, and finally turned into a vast river of characters and continued to rush forward. In the long river, dozens of lights and shadows can be vaguely seen wandering back and forth, constantly chasing the true meaning of the Heavenly Dao in it.

Qin Yu has already comprehended the true meaning of Yanwen, and deducing Yanwen is like looking down to him, he can take in all the true meaning of it at a glance, and naturally he doesn't have to look for it as hard as others.

Qin Yu hung his divine consciousness above the void and let the long river of runes run under his feet. The originally chaotic transformation process gradually became clear and three-dimensional in his eyes. Soon, Qin Yu found that the various changes in the Yanwen on this wall were not deduced together, but were divided into several layers, layer by layer, and evolved layer by layer. At the end of each layer of evolution, countless wisps of Heavenly Dao True Intent would float out and condense into a Heavenly Dao seed. And with the increase of the number of layers, the grade of the Dao is also constantly improving.

"It really lives up to the name of the heavenly wall, not to mention all kinds of changes, and it can also give birth to several completely different true meanings. ”

As the saying goes, the Tao gives birth to one, one life to two, two to three, and three to ten thousand...... After going through four layers of transformation, the number of runes conjured up by the Yanwen on the wall has reached tens of millions. Caught off guard, these massive runes were ingested into Qin Yu's divine consciousness together, and his divine consciousness was instantly expanded several times.

A stinging pain like a sword slashing at the bones surged from the depths of his soul, and in the blink of an eye, it was about to engulf Qin Yu's consciousness. His mind froze, and he quickly withdrew his divine consciousness from the heavenly wall.

Since comprehending the true meaning of Yanwen, Yanwen deduction has become as ordinary for Qin Yu as eating and sleeping, but he doesn't want to be almost planted in this heavenly wall. He opened his eyes and secretly pondered: "This heavenly wall is left by the ancient sages after they got a glimpse of the way of heaven, not to mention the changes in the universe that are derived from it, but also the truth of the reincarnation of heaven and earth. ”

He sighed and said secretly: "I originally thought that after cultivating the true meaning of Yanwen, I would be able to easily realize the Dao seed, but I never thought that I would underestimate the divine power of the ancient sages. ”

Qin Yu thought about it, suddenly came to his senses, and said with a smile: "On comprehension, I have already understood the true meaning of Yanwen; No matter how you look at it, no one should be stronger than me. If even I can't get through this hurdle, what's the point of the ancient sages erecting this stone stele? Come to think of it, this fourth-layer change is probably just a test. ”

The more Qin Yu pondered, the more he felt that this was the truth, and the more calm his mind became. After thinking about it, he put his hands in the dantian under his abdomen and began to practice with peace of mind.

If a person who cultivates the mystical world does not open his pulse for a day, he is trapped in the physical body and cannot be liberated for a day, and he has to endure many mundane things such as eating, drinking, and sleeping. The night was getting darker, and the Xuanyuan disciple who had been sitting here for a day had to leave the stone altar and go back to rest. In the meantime, another cloud boat descended from the sky and picked up the group of young boys and girls.

When Qin Yu woke up from his meditation, he found that he was the only one left in the entire stone altar. He was also happy to be quiet, took out two wild fruits from his baggage, and ate them for himself.

After eating, Qin Yu took a deep breath and threw his divine sense into the heavenly wall again. This time, he still stood his divine consciousness above the void, allowing thousands of Yanwen to flow in front of him. When the transformation progressed to the fourth level, the swelling pain from the depths of the soul came as expected. Qin Yu didn't care about it, and looked directly at the fifth layer of changes.

Unexpectedly, the number of runes transformed by the fifth layer of transformation did not increase anymore. Qin Yu was relieved and continued to look at the sixth layer. The characters in this layer do not increase but decrease, and there are only nearly 10,000 left. He only felt a light sense of consciousness, and the previous discomfort receded like a tide.

"Back to basics, simple and complex?"

Qin Yu looked thoughtfully at the end of all the changes. There, after eight changes, the entire text has returned to thousands again. Countless Heavenly Dao True Intents slowly precipitated out, gradually condensing into a Heavenly Thunder Dao Species.

This Heavenly Thunder Dao Seed has purple light all over its body, round and full, like a lotus seed that has been magnified several times, and there are several runes like thunder and lightning around it.

"A grade of Dao species, purple light and thunder!"

As soon as Qin Yu raised his hand, he wanted to take this Heavenly Thunder Dao Seed into his arms. At this moment, he suddenly frowned, and secretly said, "No!"

Since this Bi Shangyan Wen is left after the ancient power glimpsed the way of heaven, it should be in line with the reincarnation of the way of heaven, and it is right to exhaust all kinds of changes, why do you only perform eight changes? The number of eight is not in harmony with the Tao, and it does not make sense in reason! And if you want to conform to the way of heaven, you need to create another layer of change under these eight layers of changes, so that it can fit the number of nine heavens and the principle of the avenue!

"If there is really a layer of change, where will it be hidden?"

Thinking like this, Qin Yu's eyes suddenly froze, and he slammed his fist into the Heavenly Thunder Dao Seed in front of him. There was a loud bang, and the Dao Seed shook violently, and countless cracks immediately appeared on its surface.

"Sure enough, there is another mystery!"

Qin Yu snorted coldly and smashed his fist again. There was another loud bang, and the crack on the Dao seed widened bigger and bigger, and it spread rapidly. Soon, the shell of the Dao Seed completely collapsed, revealing half of the Dao Seed hidden inside.

This half of the Dao species is gray all over, looking like a cloud of mist, which is not surprising, but for some reason it faintly exudes a thick aura as vast as the sea and majestic as a mountain. Qin Yu no longer hesitated, grabbed the Dao seed and pressed it straight into his abdomen, and then returned to his body with a scroll of divine consciousness.

The moment his divine consciousness returned to his body, Qin Yu suddenly opened his eyes, only to find that the outside world was already close to the dawn.

"Have you been four hours?"

Qin Yu touched his abdomen, grinned subconsciously, and then grabbed his burden and strode out of the valley.

Soon after Qin Yu left, Xuanyuan disciples returned to the altar one after another. As usual, they threw their divine consciousness into the heavenly wall, only to find that the evolution of the Yanwen on the wall seemed to have slowed down a lot.

It didn't take long for Zhao Jian to come to the valley. After inquiry, no disciples from Qingyuanguan were found.

"Could it be that the old ancestor made a mistake?"

He waited for a while, but he still hadn't seen a disciple from Qingyuanguan.

"It seems that the old ancestor is really old and confused!"

Zhao Jian shook his head and left the valley.
