Honkai Impact 3: Saving the former civilization by rubbing the black technology

Carrying a weird system that claims that "even a fool can do scientific research", Ai Yue traveled to this era that was destined to be destroyed.
However, when he saw the name of the project called "Plasma Spark Tower" at the top of the technology tree displayed by the system, he realized that someone was going to be in trouble.
The Thirteen Heroes might not be able to defeat the Ruler of the End, but what about the 1.3 billion Heroes, or even the 3 billion Heroes?
In the end, you will be defeated by my Zepelio light!
