I Can Control Life Energy Due to Global Changes

Due to global changes, monster factories called "Tianzhu" descended all over the world. After they appeared, they continued to create monsters to prey on humans, destroying more than 90% of the population overnight. The earth was reduced to a wasteland, and only a few humans survived because they had powerful abilities to build defense lines and cities. Su Tianyu is one of the survivors, but he wants to leave the greenhouse where he is and go to the hell outside, because he is a wanderer and just likes to wander.
