Honkai Impact's Final Herrscher Likes Human Technology

He traveled through time and became the Herrscher of the End, and woke up early, but lost most of his power. He originally wanted to remain anonymous and grow up slowly, learn human knowledge, and defeat humans with human wisdom. But Naihe fell in love with Leiden Mei. When Mei was bullied by Youlandel, the Herrscher's power was exposed. Now I can only advance my plan and use my unrecovered strength and the technology I learned to fight against humans. The protagonist of this book's power comes from the Honkai Impact, and he is forced to do the work of a Herrscher, sifting out worthless civilizations, but he has justice in his heart and will never destroy those beautiful things.
