City: Start with a Technology Tree

Traveling to the Mechanical Blue Star, the most important thing is Gou. Because there are mature mechanical beasts outside. Although everyone is Iron Man, how can we fight against a mechanical version of King Kong? Fortunately, I have a technology tree. The atomic cutting sword, particle crushing knife, and positron sniper cannon are all trivial. What above is not a personal weapon? Don't be kidding, it's not a personal weapon. Why should I use it? Pangu** planet transformer. Fuxi planet computing server set**. Nuwa exoskeleton armor manufacturing system. Pangu Ax Data Weapon Library. Shennong Gene Database. Xuanyuan war system. Does Dragon Kingdom still have so many black technologies? Don't worry, I also have a hyperspace version, which uses space compression technology to be placed inside cells, do you understand?
