Genshin Impact: Great Sage, How Dare You Bully My Sister

Ye Yu transmigrates to Teyvat and obtains the Multiverse Transmigration System. To grow stronger, he immediately chooses to travel to other worlds and build up his strength.

However...

One day, when he returns, he discovers that his little sister Nahida has been locked up in the Jingsi Palace.

Ye Yu is stunned.

Didn't I arrange bodyguards?

Where's Saitama? Uchiha Madara? Thor?

Forget it, never mind them. First, I'll arrest the current Grand Sage on the charge of raping an old sow.
