After Being Expelled from School, I Unified Terra

(Time travel + system + invincibility) The soul traveled through the Terra planet, lived for 20 years, and finally got admitted to college, but was made into a Baoyan elixir by a senior sister. He dropped out of school, and was bullied online. There was a "ding" sound, and he was hanging up! This was never what I wanted. I never wanted to launch my legion into attack. Our forebears together drove away the ignorant Old Night Era. But you betrayed me, betrayed us all. You stole our rights and lied to us. Humanity only has one chance to recover if you don't seize it. Then let me finish it and let the war begin! From the territory of Terra's empire to the edge of the sky, let the oceans boil and decay fall! Even if I shed my last drop of blood, I will see humanity liberated again. If I cannot save humanity from your failure, then let Terra burn! For unity!
