"Who built this secret realm, what is the purpose of this secret realm, why is there qi in the secret realm?" Zhu Yan put down the bowl in his hand and asked while thinking.

Yang Xingchen slowly raised his right hand, pointed to the center of the round lake and said seriously: "Only by letting us crack this secret realm can we know all the answers!"

"Water! I want to drink water!Spicy~Spicy~Spicy~" The atmosphere was instantly broken by Wu Yaoxia's shout.

Wu Yaoxia successfully obtained a bottle of water and a brain melon.

The five of them had eaten and drunk to their heart's content, packed up the kitchen utensils, extinguished the fire, and walked towards the round lake.

The eye of the secret realm should be here, but how do you find it? Swim in the lake? Dive down to see?

Wu Yaoxia found a small stone from the lake, walked to Yang Xingchen's side, and asked, "Brother Xingchen, how can you throw it accurately?"

"I can't say anything trick, I just threw it at the rabbit and insisted on saying: ...... Feel...... ......?"

"Uh, that is, it's a coincidence, right?" Wu Yaoxia showed a disappointed expression, and threw the small stone towards the center of the round lake with his right hand.

The small stone flew out about thirty meters, stopped in the air with a thud, and then fell vertically into the water with a "poof!" sound.

Wu Yaoxia and Yang Xingchen were stunned, "No, the small stone should have hit something in the air, and there are also invisible walls there?" Wu Yaoxia said suspiciously.

Then he found a few small stones from the ground beside him and gave one to Yang Xingchen, and the two of them threw small stones towards the center of the round lake at the same time.

"Bang!" Yang Xingchen's stone flew high and fast, first hitting the invisible wall, and then Wu Yaoxia's stone also touched the invisible wall below the same position, "Poof! Poof!" There were two splashes in the water.

"There really are invisible walls there!" Wu Yaoxia shouted.

"Look at the splash! The ripples of the splash are not normal, as if they are blocked by something transparent, only the ripples that go outward, not the ripples that go to the middle of the lake. Zhu Yan said.

"Well, that's true! There are invisible walls there, which means that the Array Eye is really here. Ding Lingling said: "Then let's go over and take a look, there may be a door to enter." But there's no boat!

Ding Lingling looked at Wu Yaohua and motioned for him to swim over to take a look.

"Wait a minute! I don't know if there are any mechanisms in this water, and if there is any danger, I can't save you. Yang Xingchen stopped Wu Yaohua, who was about to take off his clothes and go into the water.

"I think there must be some mechanism around this round lake that allows people to go to the central part of the lake, I don't believe that the builders swam past it every time, or they took the boat with them when they left. Let's look around the lake to see if there's anything special. However, everyone still has to hold together, don't be too far apart, I don't know if there is any danger here. Yang Xingchen thought for a while and said.

So the five of them walked counterclockwise around the round lake, carefully observing the neighborhood as they went.

Unexpectedly, after walking fifty meters, I found a large stone pillar with a height of one meter, and the top of the pillar was a round stone ball.

Ding Lingling curiously went up and touched the ball, the ball was fixed on the pillar, and she didn't react after touching it for a long time.

Zhu Yan said to Yang Xingchen: "You have qi in your body, you go and touch it, will there be any difference." ”

Yang Xingchen nodded and approached the pillar, his right hand was placed on the ball, and the ball seemed to flash, but there was no reaction later.

"There was a flash!" Ding Lingling immediately said: "You try again, touch more, don't be embarrassed~"

Yang Xingchen simply put his hands on the ball together, but there was no other reaction except for flashing again.

"It's not the right way to open? Try concentrating your qi on the palm of your hand. Wu Yaoxia interjected.

"I want to too, but how can I concentrate my qi on the palm of my hand? I won't~" Yang Xingchen said helplessly.

Zhu Yan said seriously: "Try to control the qi of the dantian with your mind like in the novel of cultivating immortals, and then convey it to the meridians on your hands?"

"Control your qi with your mind? I'll try it. Yang Xingchen closed his eyes, his hands were still on the stone ball, his consciousness was on his dantian, and then he felt that there was a lot of qi in his dantian, among which there was a red air mass suspended there motionless, and the surrounding qi was all translucent and colorless, and it was flowing from the dantian to Ren Du's second vein, and then moved downward, around the buttocks, then up to the back, then to the back of the head, around the top of the head and then to the forehead, and then down to the chest. While feeling the flow of qi with his consciousness, Yang Xingchen silently recited in his heart, Qi goes to the right hand! Qi goes to the right hand! With the immersion of Yang Xingchen's consciousness, there is really a trace of qi separated from Ren Du's second vein and slowly flows to his arm.

Yang Xingchen was happy in his heart, his consciousness was a little scattered, and the qi flowing to his arm returned to the second vein of Ren Du.

No, no, you have to concentrate, you have to get the air into your hands in one go.

Yang Xingchen once again focused his consciousness on the second pulse of Ren Du in his chest, and successfully separated a small stream of air to his arm, keep walking! Keep walking! Keep walking! He kept silently thinking in his heart, although this small breath flowed very slowly, but it did not stop, like a snake crawling slowly.

Finally, with Yang Xingchen's unremitting efforts, this small breath of qi finally climbed to the end and reached the center of the palm.

"It's lit up!" Ding Lingling's voice came from beside her: "But it's only a little bright." ”

Yang Xingchen continued to concentrate his consciousness on the second pulse of Ren Du in his chest, and constantly separated the qi from the large air flow and flowed to the palm of his hand.

Probably because there was already air flowing, the air flow that had been separated from the next few times flowed faster and faster to the palm of the hand every time.

As the air flow continued to gather in the center of Yang Xingchen's right palm, the stone ball became slightly brighter.

"Xingchen, it's useful, come on!" Zhu Yan encouraged him.

However, Yang Xingchen felt that the airflow in the center of his palm seemed to be no longer able to increase, and a small stream of airflow was separated from it, and slowly flowed out again through another meridian.

Now I can only store this little bit of qi in the palm of my hand, is this going back to the second line of Ren Du?

Yang Xingchen was puzzled, but his mind was still directing the qi in Ren Du's second vein to his palm.

After a while, the qi flowing back from the palm of the hand really flowed back into the air flow of the second vein of Ren Du through that meridian, and the entire right arm formed a large reflux, and the speed of the qi flow was greatly improved.
