Atlas of Heaven and Man

Chang Ba watched Chen Chuan walk over from the beach, casting a long shadow under the rising sun. His demeanor was relaxed and natural, and Chang Ba couldn't help but mutter, "He really did it."

There really are differences between people.

But could the difference be this big?

Once the car was parked, He Xiaoxing got out.

Seeing that Chen Chuan was maintaining internal breathing, not using his mouth or nose, and presenting a very natural state, he knew that he had mastered it skillfully.

He said, "Alright, starting today, we'll begin the next stage of training. Pack up, we're going to another place."

Chen Chuan agreed. He went back to pack his things, took his belongings, and got into the car. The car started slowly and soon left the area.

After getting into the car, although he no longer needed to reject foreign objects, he didn't switch to external breathing.

Yesterday, after finding the right method, he discovered that this internal breathing method was also effective in guiding the mutated organs, and even more targeted.

If the previous breathing method used the original internal organs as a foundation to drive other mutated tissues, then now, whenever internal breathing was used, the mutated organs took the lead.

This allowed for a deeper understanding and mastery of the mutated organs' usage, and doing so also accelerated the growth of the mutated organs.

However, it was still in the preliminary stage, and besides, daily guidance and combat were two different things.

He still needed more time to master it.

Actually, even if he only learned this 'Returning Light' technique, he felt it was worth the trip.

The vehicle traveled north for half an hour and arrived at a place with a strange landform. The ground was covered with large and small pits, the small ones about one or two meters wide, and the large ones ten or twenty meters wide.

These pits were filled with red liquid, seemingly from the same source as the Dan Lake's water, but the water surface bulged upwards, looking somewhat like scarlet eyes embedded in the surface from a distance.

Although not far from Dan Lake, the style here was completely different from what he had just seen. If the former was magnificent, then this place was eerie.

Chang Ba probably knew what he was going to do next and was familiar with the area, so without waiting for instructions, he parked the car in a chosen spot, and the three of them got out.

He Xiaoxing said, "Some of these pits are naturally formed, and some are artificially excavated. Beneath these pits are underground tunnels of varying depths. The shallow ones are only about ten meters deep, and the deep ones reach several miles, but it cannot be ruled out that there are even longer ones.

What you need to do is choose one of the tunnels to enter and use the special properties of the water and the pressure underground to train your own endurance.

Underwater, you can only use internal breathing, and you also need to use other mutated tissues to resist the pressure and maintain yourself. This can comprehensively train your mutated organs, letting them know your urgent needs, so they will become stronger and more active. Therefore, the longer you persist, the better."

As he spoke, he walked to the edge of a pit and stomped on it. "Start here first." He then said to Chang Ba, "Bring him the things."

"Okay, Uncle He."

Chang Ba ran back to the car and brought out a set of unopened wetsuits, displaying it as if showing off: "This set of 'Swimming Carp' wetsuit is from the Central City's technology. You can hardly feel its existence when swimming, and it's very breathable. You don't have to worry about being scratched by sharp edges when moving at high speed. This is a good thing, even I haven't used it myself."

Of course, he couldn't say that he couldn't last long when he did this training before, so he never needed it.

Chen Chuan walked to the wetsuit and said, "Thank you, Brother Xiao Chang."

Chang Ba chuckled twice. No matter how powerful Chen Chuan was, he still had to call him 'Brother'. He happily ran over, "Come on, let me help you. Open it here, like this..."

After Chen Chuan put on the wetsuit, he moved his hands and feet and found that it was indeed very comfortable. There was no feeling of being tightly wrapped as he had imagined, and it was very light and breathable, like another layer of skin.

Because he estimated that it would take a lot of time this time, he drank a few mouthfuls of water in advance and ate a nutrition bar, and then stood on the edge of the pit.

This hole was less than two meters in diameter, which was considered narrow for him.

He squatted down and first tested it with his hand, feeling a viscous sensation, and the water had a surprisingly large buoyancy, as if it could lift his palm. There were also those stone algae inside, which meant that if he immersed himself here, he would need to constantly resist the parasitism of these things.

The difficulty was not small.

He stood up, made some adjustments in place, and then took a few steps back. He jumped, a graceful dive, and entered the pit.

After reaching the water, he moved his hands and feet, resisting the buoyancy, and slowly dived deeper. He felt that the pit wasn't very deep, about twenty meters, but he could feel the omnipresent pressure squeezing him.

And it was just the beginning. He remembered that He Xiaoxing asked him to maintain it here for as long as possible, so he sat cross-legged at the bottom of the water and began to maintain internal breathing.

Above the ground, Chang Ba walked to the edge of the pit. The splashes Chen Chuan made when he jumped down quickly disappeared, and the water surface returned to calm.

The ubiquitous pressure here was secondary. The key was not being able to hear any sounds from outside, nor see any light. It was completely dark. At the same time, the surrounding space was narrow, as if he were in a confined space, which was extremely oppressive.

The only thing he could do at this moment was to focus on his internal breathing.

He had no choice but to do so, because underwater was completely different from being on the ground. It was very difficult to capture oxygen here. He had to devote himself wholeheartedly to it, fully and rationally excavating every mutated tissue that could be used for coordination, so that he could maintain himself for a long time.

He Xiaoxing did not leave this time, but waited on the side.

Chang Ba watched for a while, then took out a folding stool, took out a comic book, and sat on the side to read and wait. But after reading it more than ten times, he couldn't help but look at the pit, and muttered in his heart, it's been almost two hours and he hasn't come out yet. Could something be wrong?

But he knew he was overthinking it. Although He Xiaoxing was standing on it, he should have a clear understanding of the surrounding situation and even the underwater situation. If there was a problem, he would have tried to pull people up long ago.

Seeing that Chen Chuan might not come up for a while, he simply took out a barbecue grill and took out skewers of mutton from the car refrigerator and started grilling them on the spot.

Before long, a fragrance filled the air, and the mutton began to sizzle with oil. He deftly flipped it while sprinkling seasoning on it.

The most ⊥ new ⊥ small ⊥ say ⊥ is ⊥ at ⊥ six ⊥ 9 ⊥ ⊥ book ⊥ ⊥ bar ⊥ ⊥ first ⊥ hair!

After grilling, he first handed more than a dozen skewers to He Xiaoxing, and then he also ate them happily, muttering to himself while eating, "I'll finish eating if you don't come out."

However, the time was longer than he thought. It was not until four hours later that He Xiaoxing signaled to him. Chang Ba quickly got up and slowly lowered a rope with a heavy object tied to the top.

Chen Chuan, who was underwater, was keeping still at the moment. He reduced all unnecessary consumption, just maintaining his own existence and resisting the invasion of those foreign objects.

At this moment, feeling something hanging down, he seemed to wake up from his silence, moved a little, then grabbed the rope and slowly came up.

Coming out of the pit, the moment he stepped on the ground, he suddenly had a feeling of seeing the light of day again.

At the same moment, he felt a burst of heaviness and weakness hit his heart. This was because he had consumed a lot of physical energy just now, but as he left the water, under the combined effect of internal and external breathing, more oxygen entered the blood, and his strength was also recovering rapidly.

He went over and took out the nutrition paste, and ate more than a dozen of them in a row, which made him feel relieved.

At present, only this kind of thing can replenish his consumption. The daily diet is low in nutrition and time-consuming. It is basically useless except to satisfy the taste.

From this, it can be imagined that those fighters in the old era consumed a lot of resources. Without the support of a large force, it would be impossible to maintain their consumption.

He Xiaoxing waited for him to recover a little, then opened his mouth and asked, "Do you feel like you've reached your limit?"

Chen Chuan thought for a while and said frankly, "Even if I haven't, it's almost there."

If he used the Second Self, he should be able to last for a long time, but under normal conditions, he was almost at the point where he couldn't bear it anymore. He Xiaoxing was still able to accurately judge his state at that time on the ground and brought him up in time. He didn't know how he did it, but he thought it was a skill that could only be mastered at a higher level.

He Xiaoxing said: "The purpose of exercise is not to squeeze potential, but to allow you to grow. This training can be done all the time, and you can slowly adapt, but you must have a clear understanding of your limits.

If you know it, your mutated tissues will also know it. In this way, with sufficient nutrients and drug stimulation, they will continue to adapt to improve their upper limit."

Chen Chuan pondered this sentence and couldn't help but ask: "Is the self-will of the fighter playing a role in this, as Teacher He said?"

He Xiaoxing said: "It's very good that you can think of this yourself. The self-will of a fighter is very important. Believing in yourself can dig out more potential power. In external manifestations, it can often create seemingly impossible miracles.

But behind everything there is a necessary reason. The reason why you can burst out power far beyond normal is only because the potential of the mutated tissues has not been developed at ordinary times, and most of them are dormant.

Only when you use special means and methods to awaken them will they listen to your dispatch, and willpower is an important part of it. Under normal conditions, it is often not enough to promote it, and many are forced to be stimulated at the critical moment of life and death.

And we don't have to be so extreme. First, through external influences and stimuli, more mutated tissues in the body will gradually become active, consciously mobilizing them step by step, and finally completely mastering them for ourselves."

Chen Chuan nodded, so he could understand. He said, "Teacher He, how long do I need to persist in this training to be considered qualified?"

He Xiaoxing said in a deep voice: "You have roughly met the requirements for the subsequent process. In the future, you will find a way to practice in your spare time. I will arrange the next training for you now."
