I Am Invincible Between the Mountains and the Seas

If he could, Luo Yun would cut off the hand he used to slap palms with them back then.

If he could, he would give himself two hard knocks on the head to stop himself from running his mouth.

But there are no second chances.

One casual boast sent him into this world. He spent thousands of years here, isolated beyond the world, trapped in the river of time, with nothing to do but lie there and watch other people show off.

When the world changed once every thousand years, he finally came ashore.

Ancient gods appeared once more in the world.

Sun god, huh? Can you reach this temperature? You can't? What a disgrace.

Water god? Can you extract protium, deuterium, and tritium?

You can? All right, forget I said anything.

Wait, friend, have you ever heard of dark matter bombs and warp travel?
