Build a Doomsday City

That day! A sudden rainbow light descended on the world, depriving most of mankind's weapons, firepower, and communications. Rainbow light, as the name suggests—— A halo entrance like a rainbow! Behind that rainbow light, there seems to be a hidden world! Creatures that have never been seen before emerge from the world after the rainbow light! In this world where rainbow light descended, He Zhiyu smashed the first batch of bosses with a steel pipe to obtain the rainbow light system. From then on, he became an emotionless person and began to build a doomsday city of his own! "Now that we have a city, I seem to be missing some brothers? (￢_￢)" "It's a brother, come and kill me! Wait online, it's very urgent!" "Brother, it's easy to discuss. The points for entering the city are 10 times higher! If you don't want to go in, go out and turn right into the Zerg restricted area. Thank you!" "Hehe... They are all my brothers, so I'm not polite. Let me see what I should exchange for today?" (The new book has set sail, please recommend it to your favorites!)
