The System Can Do Anything, Except Tame Beasts?

[A domineering System forces its love on him, a spoiled playboy becomes a big dreamer, Pokemon-inspired beast taming meets fantasy, the protagonist calls himself a playboy but is actually a super genius and a master spender. When in doubt, ask the cash.]

After transmigrating to another world, he obtains an all-knowing, all-powerful System.

Ye Xuan has barely had time to celebrate and plan to use the System to conquer the world when, one day, the sky is torn open. Blue, wormhole-like spatial passages appear all over the world, and no one knows what they mean.

Before anyone can study the wormholes, vast numbers of spirit beasts pour through them, plunging the world into crisis. Fortunately, the nations act decisively and deploy nuclear weapons, destroying the spatial passages from within.

But after just a few years of peace, the alien beasts appear again.

Then a certain Dr. Jiu suddenly emerges, announcing that alien beasts can be tamed. He forms a dedicated corps of beast tamers, and from that moment on, the world rapidly enters the age of beast taming.

But Ye Xuan, who is actually Dr. Jiu, has one complaint: the System can do everything, and his tech tree is maxed out, so why is beast taming the one thing he can’t do?
