Mowgli was speechless.

The old man said: "I have studied the Book of Heaven all my life, and I still know very little, so it is better to read it here for a day and gain something." As long as I can understand the secrets of the Book of Heaven, all my wishes in this life will be fulfilled, and even if I die, I will be satisfied and have no regrets. What's more, I have found the secret of eternal life, and I am only one thing away from it. ”

As he spoke, he pointed to the stone wall in front of him. Although Wuji couldn't see his expression clearly, he could feel his pride.

Mowgli sighed. Like Ying, the old man was also affected by hallucinations. However, he saw what he wanted to see and lingered.

"What about the Empire?

"The vicissitudes of life, there are ups and downs, and it is justified. Great Qin has been established for thousands of years, which is already rare in ancient times, and it doesn't matter if it dies. There was a disapproving contempt in the old man's consciousness. "Compared with the secrets of the Book of Heaven, the empire is not worth mentioning, and if it is dead, it will be enough to build another one. ”

Mowgli rolled his eyes again. This great master is really free and easy.

"And what about that?" Wuji persuaded bitterly, "She's still waiting for you up there." She thought you were dead and cried heartbreakingly. If you die, she doesn't want to live. ”

The old man didn't speak for a long time, as if he was hesitating. After a while, he let out a long sigh and stretched out his hand to pull Wuji: "Let's go." ”

Wuji was relieved, took the old man, and slowly went upstream.

He didn't dare to swim too fast, for fear that his body would not have time to adapt to the change in water pressure and cause abnormalities. The old man was a little anxious, grabbed ahead of him, and was very dissatisfied with his procrastination.

One after the other, they dived up four floors of the hall one after the other, and then they emerged from the water.

Ying Yiran stood on the steps and smiled happily when he saw the two of them coming out of the water. She picked up the old man and ran up the steps into the hall, which had not yet been flooded. With a flick of her palms, two bright flames appeared in her hands, illuminating her tear-stained but joyful face.

The old man let out a long breath and glanced at the rising water under his feet, revealing a look of regret.

"It's a pity, give me another half an hour, and I will be able to open the secret of eternal life. ”

"Eternal life, give you another half an hour, and you will be out of gas. Wuji took off the clothes on his body, wrung the water, and said: "Sir, you also reminded us to pay attention to the three corpse gods, I see that you yourself have been controlled by the three corpse gods." ”

The old man smiled silently, did not speak, his eyes flashed, and he did not know what he was thinking.

After a while, the lake rose up and slowly poured into the hall.

The three of them hurriedly climbed up. In order to prevent the old man and Ying Yiran from being attracted by the Book of Heaven and forgetting about the dangers around him, Wuji simply took Ying Yiran and the old man to climb to the top floor, the circular hall.

"This is the heavenly book of the Jiuyi tribe. Wuji pointed to the picture on the wall and said, "Isn't it a little strange?"

The old man was stunned for a moment, and nodded again and again. "What volume is this?"

"The last volume. Wuji pointed to the top of his head, "There is a small layer on it, but there is no heavenly book in it, and it is pitifully small, and it can't squeeze three people at all." ”

Ying Yiran's face changed: "In other words, if the lake floods this layer, we will die?"

"Actually, we're dead now. Wuji sat down cross-legged, put his hands together in front of him, and blew softly. "Sir, do you know how high the water will rise and how long it will take for it to recede?"

"Retreat?" the old man hesitated for a moment, understood what Mowgli meant, and couldn't help but smile bitterly. "On this day, the water of the pond will continue to flood Zifu Mountain, reach the dome, and then overflow from the Sun Moon Lake. ”

Mowgli chuckled in his heart. He didn't know what Sun Moon Lake was, but if the lake rose to the dome, they wouldn't be able to escape from this position.

"So, we're dead?"

The old man nodded, looking at Mowgli apologetically.

"As far as I know, no one who has ever made it out alive from Zifu Mountain has ever reached the third layer, usually only to the first layer, and only one or two people have ventured into the second layer to observe the Transfiguration Heavenly Book. After leaving the customs, the cultivation of these people has advanced by leaps and bounds, more than ten years, less than a few years, without exception, they have reached the peak of the Xuan Realm, becoming a myth of the times. ”

Mowgli now doesn't think about myths, only about survival. He immediately grasped the key. "In other words, if you can't escape before the water floods the Transfiguration Scroll, you're dead?"

"That's how it should be. The old man sighed lightly: "This may be the will of heaven, those who glimpse the heavenly machine are ominous, and only by dying can they keep the heavenly machine." ”

"However, so many people have been drowned in this twenty-four-step spiritual platform, why are there not a single skeleton?" Wuji pointed to the empty hall and said, "Since we entered the spiritual platform, we haven't seen a single skeleton, where did those who were drowned go?"

The old man shook his head: "This ...... I don't know. ”

Ying Yiran suddenly showed a look of horror. "Sir, Mowgli, could it be...... This altar will collapse, and the drowned ones will be reduced to dust, and then ......"

Wuji pursed his lips, feeling a little unbelievable. "A new altar every year?"

Ying Yiran nodded, shivering involuntarily.

Wuji also felt that his back was a little cold, and although Ying Yiran's conjecture was not very reliable, it could not be said that there was no possibility at all.

Isn't that dead, and even the scum left?

"Shall we ...... What should I do?" Wuji's throat was a little dry, and his voice was astringent, with indescribable despair.

And so on. The old man slowly regained his composure. "Wait for providence. If Heaven wants me to be born, I can be born. If Heaven wants me to die, I can only die. ”

Wuji glared at the old man, and stopped talking. He now finally understood what the old man meant by one in a million. However, it is no wonder that the old man has warned him many times not to follow, and it is he himself who has to follow.

It's just that...... Who would have thought that this Zifu Mountain would be so pitiful, and this twenty-four-step spiritual platform is simply a sinkhole. Looking at it like this, it is estimated that the old man himself does not know, otherwise he would definitely not have dragged it out until now, and he will run away after reading the first and second volumes, and there may be a glimmer of life.

"Then wait. Wuji's thoughts were discouraged, but his mood calmed down. As the old man said, he is a person who went to the land of past lives and experienced life and death, and death is not so terrible for him. Maybe you can be born again and experience a new life.

In this case, you might as well take this opportunity to study the Book of Heaven, and you can have a little more capital for the next rebirth.

Mowgli walked to the circular wall and looked at the book of heaven on the wall. Ying Yiran also walked over and quietly stood beside Wuji. Wuji turned his head to look at her, just met her gaze, looked at her red and swollen eyes, and couldn't help laughing.

"You can still laugh?" Ying Yiran's voice was muffled.

"If you don't laugh, do you cry?" Wuji reached out and hugged Ying Yiran's shoulder. Ying Yiran hesitated and didn't push away.

Wuji slowly rubbed her round shoulders and exhaled softly: "Actually, death is nothing to be afraid of, it's like a dream, it's just that when you open your eyes, you're not in your own bed, but in a strange place." ”

"It's like it's true. Ying Yiran wrinkled her nose and gently leaned on Wuji's shoulder. "Are you really going to the Land of Past Lives?"

"I don't know, maybe. Mowgli scratched his head. This question couldn't be explained clearly, so he diverted the topic, pointed to the book of heaven in front of him and said, "Do you know how this book of heaven is different from other books of heaven?"

Ying Yiran looked around, lacking interest, and just asked casually: "What's the difference?"

Mowgli smiled. The old man said that Ying Yiran was not a suitable candidate to be a great teacher, and he was not wrong at all. She is interested in a lot of knowledge, and she also has extraordinary attainments, but she has no interest in the Book of Heaven, at least not like the old man, who can die at night.

"First of all, the content of this book is the least. ”

"Well, what else?"

"Secondly, the Heavenly Book Hall in front of it is square, but this hall is circular. Any idea why?"

"Why?" Ying Yiran closed his eyes and replied unintentionally.

"Do you know what the characteristics of a circle are?"

"What are the characteristics?"

Wuji turned his head to take a look, and saw that Ying was also sleeping instead of sleeping, and couldn't help but be surprised. Could it be that she is short of oxygen because of insufficient oxygen? He pinched Ying Yiran's nose and shook it slightly: "Hey, what's wrong, is it not strength?"

"Nope. Ying Yiran opened his eyes, pushed away Wuji's hand, and rubbed his nose. "Listen, what are the characteristics of a circle?"

Wuji breathed a sigh of relief and continued, "A circle is the most perfect shape. It has no beginning or end, and any point can be a beginning or an end. Compared with the previous Book of Heaven, the biggest feature of this Book of Heaven is that it can start from any place. ”

"Really?" Ying Yiran closed her eyes again and replied nonchalantly.

"Yes, in the end, there is one more great feature of this heavenly book. If there is no book of heaven, the first twenty-three volumes of the book are dead and cannot play a role, with this book of heaven, the twenty-three books of heaven can be useful, and can be derived into thousands of changes. ”

"Why?"

"Because ......" Wuji was suddenly stunned, and a flash of inspiration made a new discovery.

If his guess is correct, then this book is about mitochondrial DNA. Mitochondria are also known as power factories and provide energy to cells. The Jiuyi tribe does not pursue body deformation, but absorbs the vitality of heaven and earth to become stronger, which should change the structure of mitochondria, coupled with the special role of Ziyue, so that they can use energy more effectively.

In visible light, the energy of violet light is originally the strongest.

Theoretically, there is nothing that cannot be done as long as there is enough energy.

Similarly, if he had enough energy, he could completely break the Lingtai and rush out of Zifu Mountain.

According to his rough estimates, they should be on the top of Zifu Mountain by now, and the volume of the mountain above them is limited. For ordinary people, it may be indestructible, even if it is a third-order Ying of the Xuan Realm, there is nothing they can do. However, what if he could unlock this heavenly book and increase the energy utilization efficiency by ten or even a hundred times?
