In a galaxy far away, there is a kid without innate ability to practice internal techniques. So, in order to gain the respect of his father, he resolutely chooses to follow the more difficult and painful path of practicing external techniques. As the years go by, he grows up, but what really changes his life is a mysterious meteoric crystal stone – the Meteoric Tear. This stone fuses with the young man’s body unnoticed, and he seems to undergo drastic transformations as a result. After that, everything is changed. Eventually his father knows that the son for whom he hasn’t really shown a lot of consideration possesses astonishing abilities. And there’s a lot more to come.

Soaking in lava, sleeping in an Ancient Killing Formation;

Traversing alternative worlds in a heavy armored vehicle;

Riding a Gundam Sentinel and slaying immortals with Godzilla...

I got myself a stat system, and from then on, I only beefed up my defense!

I just can't help it, I'm afraid of pain! The Daluo Golden Immortals of other worlds are all really fierce, and all of them know super ultimate move with infinite power. They have little meetings every day to discuss how to break through my defense.

I really don't know why they're so obsessed...XD
