I Transmigrated to Save the Heroine, and Ended Up Saving Earth Too

The beast tide made landfall, and humanity was wiped out.

The love of his life died fighting to protect China.

Bu Feiyu activated the Universal Upgrade System and transmigrated back to three years before the beast tide arrived.

All he wanted was to stay by his beloved's side...

But along the way, he joined a research institute, became a frontline researcher, a leading figure in science, and a martial arts powerhouse...

He also developed the third-generation Awakening Stone, increasing its success rate from the second-generation stone's 20% to a full 70%.

The world was shaken!

But Bu Feiyu insisted, "Keep it low-key. I just want to join the martial arts class."

Everyone was dumbfounded. "Are you crazy? You could be a general or chief engineer at a research institute, but instead you insist on risking your life on the front lines?"
