There Is a Cave in the Campus Lake

Xuan Zhi is an ordinary high school sophomore who accidentally fell into the school's lotus pond while sketching in the art class. He thought that he, who could not swim, was about to face the greatest disaster in his life, and his usually quiet life would be gone forever. However, he found that because of a stone, he did not get a drop of muddy water on his body. There was a cave under the lotus pond, and the secrets of the campus were waiting to be discovered. (No training, just superpowers, centered around high school campus life.)
