Spark Era: Inherit the Three Kingdoms Mecha at the Beginning

Chen Yu was reborn in the Three Kingdoms and became an eight-year-old child from a remote branch of the Chen family in Yingchuan. He thought he could live a stable life with modern knowledge, until he touched the ancestral bronze fragment, and the memory of his past life suddenly awakened—— He is actually the last "fire" of the ancient "Yu Clan" civilization, and thirty years later, an extraterrestrial reaper named "Youying" will come to earth. At that time, the Three Kingdoms were in a state of power, and all the heroes came together. Cao Cao's tiger and leopard cavalry were equipped with heavy armor, Zhuge Liang's wooden ox and flowing horse were equipped with particle cannons, and Sun Quan's building ship guards deployed laser sails... When everyone was fighting for hegemony in the Central Plains, Chen Yu led his expedition team deep into Sanxingdui and opened the "Hidden Mist Valley" that had been dormant for thousands of years. What he wants to do is not to fight for the world, but to restart China's lost ancient technology before the invasion of extraterrestrial civilizations, and to earn a glimmer of life for this planet. "You guys are beating me up, I just want to build a mecha that can kill gods."
