Transmigrated and Invincible

My name is Li Tian. I was a lowly wage worker at the very bottom of society on Earth in the twenty-first century. Then, by some fluke, I transmigrated to a world where martial strength reigns supreme. Li Tian had thought he might as well spend this life slacking off and waiting to die, just like in his previous life. But after he fully absorbed the original owner's memories, he was stunned. It turned out I was invincible.
