Long Live Long Live! but I Can Really Live Forever

Qin Changsheng traveled through time and became an emperor, but was stabbed to death on the day he ascended the throne. Then he lived. He was poisoned again, and then he came back to life. He discovered a pattern: as long as someone remembers him, he will never die. So he began to engage in science, build cannons, and raise mythical beasts, vowing to make the world remember him. Heaven was in a hurry and sent down tribulations to kill him, but failed every time. What's even more outrageous is that he lived to be twenty thousand years old and awakened five forms. Nian (his pet, an arrogant ancient beast) commented: "Ouch!" (Translation: The owner is awesome!)
