Changed to the Lord of the Past, and the World Will Be Destroyed If He Takes Action

If you are tired of watching the losers who shout "Thirty Years of Hedong" at the beginning, and tired of the routine of max-level bosses re-installing as novices, then this book will definitely give you a new life. The time traveler Chen Yu, a public servant without a father or a mother, awakened an unprecedented Z-level profession in a world where everyone changed jobs - "Disaster and Lord of the Old Days". The whole school thought he was a joke worse than an F grade. His ex-girlfriend's best friend even came to him and said, "Give Fang Hao your 20% additional points for the college entrance examination. In exchange, I will watch a movie with you alone after the college entrance examination." Listen, is this human language? Chen Yu retorted on the spot, and by the way, he made this "Beautiful Liu" so angry that he doubted his life. But no one knows that this Z-level profession is not garbage at all, but the only hidden profession above the SSS level. As soon as the two concept-level talents were unveiled, Chen Yu directly turned on the "plug-in mode": by imagining the strange existences in the Cthulhu Myth, he could summon unreasonable servants of disaster such as Khazik the Void Predator, Red Moon the Ghost Bride, and Yog-Sothoth the God of Time and Space, into reality. When others play the dungeon, they must be cautious, team-oriented, and tank output is indispensable; when Chen Yu plays the dungeon, he places the three Servants of Disaster in that direction. The health bar is already empty before the BOSS can even see what they look like. People living in destruction and disaster have a unified voice: "Go to Chen Yu, he is the savior of mankind!" As for how the disaster came about, you'd better not ask! !
