Ye Ran transmigrated and got an extremely tsundere System named Yaya.

Most importantly, this System is even more tsundere.

Want a reward?

Hurry up and spend some money!

Spend one million for a Bronze Draw.

Spend ten million for a Silver Draw.

Spend one hundred million for a Gold Draw.

Spend one billion for a Diamond Draw.

The more you spend, the more you draw!

Ye Ran was surprised to discover that as he kept spending money, he had become invincible.
