Sleep

The Qi was being used up much faster than normal inside the water, but he was okay with that. As long as he knew what was inside the water, he would be fine. 

He ran around at full speed with his spiritual sense looking at everything. 

After a few seconds, he saw something ahead of him. He walked forward hoping it was a talisman, but instead it turned out to be a key. 

It looked very new and looked slightly blue underwater. He quickly kept it with him and search around a bit more. He found 2 extra talismans. 

One gave him a 40-second reduction, and another gave him a 24-second reduction. 

Finally, he brought back friction and swam up before flying out of the lake. He took a deep breath and immediately flew to the other side without any delay.

He then entered another maze. He was walking forward when he suddenly met Yang Ma returning back from another pathway of the intersection.
