Even if you sleep inside, people outside cannot see you.

"Except the first one which is occupied, you can choose any other one." said the person who led Lu Qing'an here.

Lu Qing'an thought about it and finally chose the 30th and last room.

He was worried that due to his special physique, he would absorb the vitality too quickly. If he chose to go in front, he might absorb the vitality in the undercurrent too cleanly, which would cause trouble.

It’s different in the last room. No matter how much vitality you absorb, there is no one behind you and you won’t be discovered.

So, under the slightly strange gaze of the guard, Lu Qing'an stepped into the last stone chamber.

After closing the door, Lu Qing'an looked at the undercurrent flowing below. The water was no higher than his knees, flowing slowly and quietly. He could sit cross-legged in it without being washed away.

"Sure enough, the vitality here is rich!"

Even before he entered the water, he could already feel the vitality in the air. Once this vitality approached him, it seemed as if it were being drawn by something, immediately flowing into his body and being rapidly absorbed.

It was also like it was his life force that had wandered around and finally found its home, suddenly entering his body.

"Just the vitality in the air can actually extend my lifespan by ten days?" Lu Qing'an felt it carefully and his eyes lit up.

He could see that the vitality integrated into the undercurrent was much richer than that in the air.

What would happen if his body came into contact with this undercurrent of spring water?!

"Very good! Let's get started! Try to increase your lifespan as much as possible, and see if you can improve your cultivation as well!"

Lu Qing'an took a deep breath and did not rush into the water. Instead, he carefully explored the area to make sure there was no danger. Then, he was too lazy to take off his clothes and jumped forward.
