The Poorest City Lord, All My Men Are the First to Cause Disaster.

[Wasteland City Construction + Campus Superpowers + Multiple Female Protagonists] Lu Chen awakened the F-level ability [Retention Fire] - it can only give something that is about to be scrapped another breath of life. In order to collect money for his mother's medicine, he broke into the Zero Restricted Area alone, just to pick up valuable disaster materials, but was forced into the dead city that had been dormant for seventy-three years by the Realmback Beast. In a desperate situation, he used [Leave Fire] to wake up the final emergency takeover, closed the city gate, and registered himself as the city lord. Zero energy, zero inhabitants, purification shut down, borders lost. After Lu Chen read the city affairs list, he just wanted to ask: Can this city be withdrawn? What's even more troublesome is that the city still contains twelve "initial disasters" that destroyed the world. The first person to trade with him was the girl in red, Hongxiao. From then on, Lu Chen hid his identity as the city lord during the day and entered the Federal Disaster Disaster Academy as an F-level technical student; he repaired the city, saved energy, and awakened the disaster at night. It wasn't until the dark sun came again that the world discovered that the dead city abandoned by the world had become the last line of defense for mankind.
