Perhaps it is the choice of fate. As a senior otaku, Qian Lingfeng got the “steel shell system”.

Where will weak human beings go in this world? Is humanity going to be extinct? Or … can an otaku save the fate of the human race?

“Papa, this dragon doesn’t taste good!”

“Oh, this must be an ancestor-grade dragon that has lived for much too long. Its meat has become a little dry. Next time, we shall eat a young dragon within ten thousand years of age.”

“Papa, between you and the other Immortal-emperor mannies, who is more powerful?”

Xue An smiled. There was not a single soul that could withstand even just one blow from him. If there was! That would at most be two!

“My dear daughters, I will make you girls the happiest princesses in this whole, wide world. No, in this whole universe! And it’s the two of you!”

“One Generation Immortal Venerable” Luo Chen was attacked and reborn and returned to Earth.
