"Wow, the peaks are turning around, I can't imagine that there is another scene up here," Xiao sighed.

"Indeed, according to the map provided by the village chief's grandfather, our destination is not far ahead, work hard, hours," Chu Jingxuan said.

After walking for about half an hour, a small piece of emerald green water appeared in front of the two of them.

"That's right, this is it, it's finally here, fortunately, the journey went well." Chu Jingxuan said. "According to what the village chief's grandfather said, you should first practice the basic skills and hold your breath until you are perfect."

"But how do you practice?" Hour asked, widening his eyes.

"Do you see the lake here, let's start here, I heard the village chief's grandfather say before, this lake is different, it is a good place to practice holding your breath, but for most of them, holding your breath is a waste of energy and does not have much practical effect, coupled with the changes in the surrounding environment in recent years, naturally no one pays attention here" Chu Jingxuan looked at the calm lake and said.

"Then why did the village chief's grandfather let you practice this?" Hour asked again.

"Then I don't know, since the village chief and grandfather have put it forward, I believe that practicing this will definitely be useful in the future," Chu Jingxuan said affirmatively. "Although I usually have a practice holding to absorb qi, it is still too far from being perfect, and the time is limited, so without further ado, let's start now" After saying that, Chu Jingxuan took out a rope from his backpack.

"What are you doing with the rope?"

"If you want to quickly improve the ability to absorb qi, you have to go deep into the lake and isolate yourself from the outside world. And I have only heard of this lake, and I have not really touched it, and I don't know what is underneath, just in case, I will tie the rope around my waist, and put the other end in your place, if there is an emergency, I will shake the rope, and you will quickly pull me back" as he spoke, tying the rope and handing the other end to the hour.

"I see, it's better to be thoughtful," the hour nodded. "Don't worry, if I see the rope shaking, I will pull it back immediately, Miss Ben will do what she says"

"Well, then I'll go down and try it first" Chu Jingxuan didn't say much and walked straight to the lake, then bent down and tested it with his hand, and after making sure that the lake was harmless, he took a sharp breath and jumped into the lake.

However, to his surprise, he felt something strange as soon as he entered the water, the tightness of this lake was much larger than that of ordinary water, and the content of air in the water was extremely low, Chu Jingxuan tried to obtain air from the lake with his own strength, but soon it turned out that this method was not feasible, because he had not had time to inhale enough air into his body, he felt that his physical strength was excessive, and it would be really dangerous to go down. I could only pull the rope, and the hours outside quickly pulled it out of the water.

"Hey, it's only been less than half an hour, it's not like your usual level," Xiao said in surprise, according to her usual understanding of Chu Jingxuan, it was no problem to hold her breath for a quarter of an hour.

"Well, I'll try again" This time Chu Jingxuan inhaled more air at one time, and then jumped into the water with a plop, originally thinking that the time would be longer than the last time, but he didn't expect that he was also pulled out of the lake by the hour at a similar point in time. Just when Chu Jingxuan took a big breath and was about to enter the water again, Xiao suddenly said, "It must be the wrong method, or there is something wrong, don't jump in again"

"Huh? The method is not right," Chu Jingxuan asked.

"Yes, you think, the amount of air you inhaled the second time and your preparation are much more adequate than the first time, and you spend the same amount of time in the lake both times, which means that it is not a problem that can be solved by inhaling more air." The hour analyzed slowly.

"It makes sense, why didn't I notice this," Chu Jingxuan said while patting his head. "I guess, no matter how much air is breathed in from the outside world, it has no effect in this lake, and I can only rely on my own internal force to absorb the air in the lake, and that is too much physical exertion, with my current realm, the speed of physical recovery is far from keeping up with the speed of consumption."

"Didn't we have a few pills from Uncle Zhang, you can try to restore your strength in the water," Xiao said.

"That's right, it can just be used to verify my next conjecture" With that, Chu Jingxuan took out a black pill from his pocket and put it in his mouth, then gestured to the hour, and jumped into the lake again.

When he was about to exhaust the air in the lake, Chu Jingxuan quickly swallowed the pill in his mouth, and as the pill entered his abdomen, Chu Jingxuan's physical strength was gradually recovering, and this time, he finally successfully inhaled the air in the lake into his body, and with the continuous inhalation of the air in the lake, Chu Jingxuan found that his physical strength was also constantly increasing, as if he would be full when he entered the water for the first time, "And such a good thing?" Chu Jingxuan was secretly happy in his heart, and he didn't think much about it, so he continued to use his abundant physical strength to refine and absorb the air in the lake, and went through five rounds in a row. After absorbing the refining air again, he obviously felt that the upper limit of his physical strength had not been raised again, so he stopped. "I don't know how long it has been, let's go out and see the hour first" Thinking of this, Chu Jingxuan pulled the rope around his waist, and was pulled out of the water by the hour in a moment.

When I came out of the water, it was almost noon.

"I think you're right to stay so long this time," Xiao said.

"Well, this lake is amazing," Chu Jingxuan said, and then told his experience to the hour. "I think that this time, with my physical strength, I can continue to refine the air inside. Hours, you can go down and exercise too," he said, taking a pill from his pocket.

"Well, however, the village chief's grandfather explained to me before, saying that it was my own reason, and I didn't need to cultivate anything to absorb qi, so forget it, don't waste time," Xiao said with a little regret. "The village chief's grandfather said, I have prepared some gadgets for you here, have you found them?" asked the hour.

"Well, this, I'm afraid you're worried that you forgot to observe the underwater environment carefully, it's almost noon, let's eat something, I'll go in and explore later" Chu Jingxuan said.

"It's okay", said that, took out the dry food they were carrying, and the two of them hastily solved the lunch problem.

After resting for a while, Chu Jingxuan dived into the sunset spring again, after the previous experience, this time he did not tie a rope, but entered the water to suck in the air first, and then walked slowly along the bottom of the lake, this time he finally saw the scene in the lake, only to see that there were nine springs at the bottom of the lake, bubbling out of the water, and there was an inconspicuous stone tablet in the center of several springs, with the words "sunset spring" written on it. "Originally, this place was called Sunset Spring." Chu Jingxuan thought to himself.

When I suddenly looked up, I noticed that a small area not far ahead was in a colorful shape, and the flow of spring water was like a sunset. Chu Jingxuan walked curiously towards the glowing place.
