Invincible Starting with Killing Vampires

[Original World, Invincible from the Start, Pseudo-Infinite Flow]

Half a year after transmigrating, everything had been peaceful, and Xia Ye thought Source Star was a normal world.

But what was going on with encountering a vampire on the very first night of summer vacation?

"Go to hell!"

And so, the vampire died.

"Host has encountered a monster. The God-Tier Demon-Slaying System is activating..."

"Activate, my ass! You didn't show up when I ran into the vampire, so what's the use of showing up now? Go to hell!"

And so, the System exploded.

"The Dimensional Chat Group has invited you to join. Do you accept?"

"Now that's something. I accept."

Shinjo Daigu: "Xia Ye, Gatangea has turned into twins. We need backup!"

Rikka Takanashi: "Brother Xia Ye, there's an evil transmigrator over here. It's terrifying!"

Hitagi Senjougahara: "Xia Ye, the King of Oddities is going to destroy the world. Can you come stop her?"

Klose Rinz: "Xia Ye, a floating city has appeared, and the orbal technology across all of Liberl has stopped working. The Erebonian Empire wants to take advantage of the situation. Please help me!"

Tony Stark: "Xia Ye, the cosmic Avengers' director is here. Come help me take him down. The Infinity Gauntlet is yours."

Bruce Wayne: "Xia Ye, Clark has gone bad. Can you help me knock some sense into him?"

Xia Ye: "No problem. Leave it all to me!"

Everyone: "It's great having a big shot in the group. Now we can all lie flat!"
