Mowgli thoughtfully.

The three corpse insects mentioned by the old man, especially Peng Ju in the upper dantian, are somewhat similar to the Siren Sirens in Western mythology, all of which use people's hallucinations to cause death.

Illusions, though, are just illusions after all. Hallucinations themselves can't hurt people, but what can hurt people is the body that is controlled by hallucinations.

Illusions can't make people lose their souls, what makes people lose their souls is the desire in people's hearts. Illusions only arouse people's desires, make people unable to extricate themselves, and indulge in them.

"Sir, what is your greatest wish?" Wuji said to the old man.

"What did you say?" the old man turned his head and looked at Wuji, his eyes flashing with doubt.

They have been together for so long, although Wuji is not familiar with etiquette and is a little disrespectful, he is not a person who likes to ask around. No matter how curious he is, he doesn't take the initiative to pry into other people's privacy. Suddenly asking this question at this moment is not quite in line with the impression that Mowgli has always given him.

Mowgli smiled. Of course, he didn't want to inquire about the old man's privacy, he just wanted to give him a little hint in advance. As a great teacher, the old man may have a profound understanding of spiritual practice, but he has enough confidence in the structure of the brain - although he is not a student of brain science.

He is so confident for two reasons:

First, the brain and the universe are two of the most fascinating topics in modern science, and although Mowgli does not study these two topics, he has always had a strong interest in these two topics. The real brain science research is based on the progress of physics, and the emergence of advanced instruments such as nuclear magnetic resonance has enabled human beings to obtain more brain science knowledge in a short period of time than the sum of the past few thousand years.

Second, genes related to the brain are the focus of genomics research. Although the brain only accounts for 2% of the body's weight, the genes related to the brain account for 80% of the total number of genes.

In other words, although he is not an expert in the field of brain science, his knowledge of brain science still has enough advantages, especially compared to the great masters.

Tong Guò's mutual confirmation of the Book of Heaven shows that he has been able to basically grasp the scientific and technological level of the Great Qin Empire.

A zombie-like empire, let alone a thousand years, even if it is ten thousand years, it is impossible to produce real technology.

Modern science was originally based on reason and respect for human nature. An empire that ignores the dignity of ordinary people and only knows simple and crude conquests, where the upper elites indulge in enjoyment and the lower classes are ignorant and ignorant, it is impossible to produce real technology.

The great master is very knowledgeable, but there is much rationality in his knowledge, Wuji is quite skeptical. If it were usual, he might have reserved his opinion, but now that he is in a life-and-death crisis, he can't squander the few opportunities he has because of his so-called modesty.

"I heard from the gentleman that the danger of these three corpse insects is likely to stimulate people's minds, provoke people's inner desires, and make people's hearts crazy. ”

Mowgli said carefully, he didn't want the old man to think that he was talking nonsense and ignoring the real topic. So what you're going to see may be incredibly related to what you're trying to see. ”

The old man pondered for a moment, bowed his head slightly, and provoked a meaningful smile at the corner of his mouth.

"You are right, maybe it is not the illusion that makes us move, but the desire in our hearts. ”

Mowgli nodded in admiration. The old man's scientific knowledge may not be abundant, but his wisdom cannot be ignored. He turned to Ying Yiran again: "What about you, what do you want to see the most, and what are you most afraid of seeing?"

Ying Yiran looked at Wuji with a blank face. She didn't have the wisdom of the old man, and she didn't understand what Mowgli was talking about.

"Mowgli means that if you see something that makes you happy or frightening, you should be vigilant, it may be an illusion caused by Peng Ju, don't be fooled by it. ”

Ying Yiran understood and nodded silently.

The old man chuckled lightly and asked, "Wuji, what do you want to see the most, and what are you most afraid of seeing?"

Wuji was stunned and blinked in disguise.

"Mowgli, it is easy to know people, but it is difficult to know oneself. The old man said lightly: "The sages have clouds: the greatness of the world is not in heaven and earth, but in one heart." There are many difficulties that we can overcome, but the most difficult thing to overcome is our own walls. If you want to know the avenue, first break the heart wall, see the nature of the heart, and prove Bodhi. ”

Mowgli didn't say anything. The old man said very mysteriously, with a bit of idealism, but it contains real wisdom in life.

What do I want? What am I afraid of?

Mowgli asked himself secretly, but found that there was no clear answer.

The old man didn't ask, just as he didn't answer Mowgli directly. All they want is to remind each other, not to peek into each other's hearts.

They were silent with each other, rowing their bone boats, and moving on.

There was silence all around, except for the sound of stone paddles plucking the lake, only the breathing and heartbeat of the three people.

Occasionally, the old man would let out a roar.

......

Suddenly, another day passed.

The expected Zifu Mountain was still nowhere to be seen, and there was only boundless black around it.

"Something isn't quite right. The old man who had been sitting on the bow of the boat suddenly said, "Why haven't you reached Zifu Mountain yet?"

Wuji and Yingyi exchanged a look, and couldn't help but get nervous.

"Sir, are you sure?" Ying Yiran asked loudly, "Could it be that we went in the wrong direction and missed?"

The old man shook his head. He had been observing the star-like light above him, and he was sure that he had been moving in the right direction.

"That'...... Won't it be there yet?"

"Zifu Mountain is a mountain peak, and it is not a small thing, how can it escape my listening and identification?" The old man turned his head and glanced at Wuji: "Wuji, according to your estimate, how big is the Tianchi?"

Mowgli stopped the oars and pondered for a moment.

"Sir, how many miles can you detect targets within your ears?"

"Within thirty miles. The old man said calmly, as if this was not something to be proud of at all.

Mowgli was taken aback. The old man sat cross-legged on the bow of the boat, and Mowgli sometimes saw him pursing his lips and howling, and he had already guessed that he was using a method similar to bat echo positioning to determine whether there was an obstacle ahead, but he didn't expect that the old man's detection distance was as far as thirty miles.

"My life is a spirit turtle, and I have been practicing turtle breath since I was a child, and it has been more than 50 years now. Seeing that Wuji was surprised, the old man explained lightly. "This place is empty, there is no noise and interference, as long as the radius of Zifu Mountain is not less than 100 steps, I can ensure that there will be no misjudgment within thirty miles. ”

Wuji raised his head, looked at the pitch-black dome, looked at the star-like points of light on the dome, and suddenly said, "Sir, how tall is here?"

"Fifteen miles, the error will not exceed two miles. ”

"Do you think those spots of light are getting bigger?"

The old man also raised his head, looked at it for a moment, and shook his head. "I don't see any changes. However, my eyesight is not as good as yours, and maybe you are right. What, you think it's getting bigger?"

Mowgli nodded. He didn't have the old man's ability to hear and discern, but his eyesight was good. According to the old man, he has already stepped on the threshold of the innate eye with one foot, and his naked eyesight is at least close to the level of the arrow saint, if not comparable to the legendary arrow god.

He noticed subtle changes in those highlights.

In the dark, if there is no reference, even if he sees a bright spot, he cannot judge the distance of that bright spot. However, when he moves, he can roughly calculate the distance through the slight changes in the angle.

Before entering the Tianchi, when he and Ying Yiran were chasing each other on the beach, he began to pay attention to this. After paddling on the Tianchi for two days and one night, after countless calculations and verifications, he had roughly calculated the height of the dome.

In his opinion, the dome is actually not very high, about twenty miles, and the reason why it looks high is because the light is too dim, giving people the illusion of being very far away.

According to the height of the dome, and according to the change in the distance between the different bright spots, he can roughly determine that the width of the heavenly pool should be about one hundred and fifty li. If Zifu Mountain was really in the middle of the Tianchi as the old man said, then they should have arrived.

However, within a radius of sixty miles, the old man did not find any peaks.

"Yes, I think the water level seems to have gone up quite a bit. Wuji lowered his head and looked at the lake beside the boat with the flame in Ying Yiran's palm. The lake was dark, and the firelight could only illuminate a small area, which was soon engulfed in darkness. "I think the dome should have been about twenty miles long. ”

Before the old man could speak, Ying Yiran interjected: "You mean to say that the lake has risen for three to five miles, and Zifu Mountain has been flooded by the lake?"

Mowgli nodded. There was a difference of three or five miles between the results estimated by him and the old man, and if both of them were correct, then Zifu Mountain might indeed sink underwater. Even if it is not completely submerged, if only a small part of it is on the surface, the old man may not be able to tell it.

The resolution of sound is inherently inferior to light, especially at very long distances.

"It's simple. The old man got up and took off his coat and took out a rope and tied it around his waist. "When I went into the water, I knew what was true. ”

"Well, it's too cold in the water. Ying Yiran refuted and changed color: "Sir, you will freeze to death." ”

"Within ten breaths, I can still hold on. The old man smiled: "You are ready to save me." ”

Ying Yiran wanted to say more, but Wuji stopped her, took out the purple blood dragon zhi from his arms, opened the lid of the box, and stuffed it into her hand. "You breathe first, get ready to treat Mr., and I will help him. ”

The old man nodded in satisfaction. "With your help, I may be able to support ten more breaths, as long as Zifu Mountain is within thirty miles, I can find it. ”

Wuji smiled, didn't say anything, squatted in front of the old man, took off his shoes and socks, put his palms on the old man's feet Yongquan acupoint, closed his eyes, took a deep breath, and slowly spit out. As soon as Tianmen was numb, the rich vitality poured in from Tianmen, and the electric light flashed in his mind, slowly spinning. After dozens of breaths, the swirling energy turned into a mass of heat that looked like a substance.

Wuji cocked the tip of his tongue, the top of his tongue on the palate, and led the heat flow down, along the Ren vein, until the middle of the chest, and then divided into two, pouring into both palms, gushing out from the Lao Gong acupoint, and slowly injecting into the old man's Yongquan acupoint.

The old man's originally pale face slowly became rosy, and even his eyes became a little brighter. He was surprised and delighted: "I didn't expect it...... You actually cultivated to Xiao Zhoutian so quickly and connected to the congenital fetal breath. ”
