Commanding Billions of Immortal Soldiers, and You Call Yourself the Immortal Emperor?

[System + Immortal Kingdom Management + Multiple Heroines + Summoning + Decisive and Ruthless] (This novel has multiple heroines. Please don't read if that's not your thing.)

Wu Yu transmigrates more than ten years ago. Only after his memories awaken does he realize that he has just ascended the throne and become ruler of a nation.

He had planned to be a foolish ruler, have more children, more blessings, and enjoy a carefree life. But then he discovers that this is a cultivation world, where the strong abound and sects lord it over the mortal dynasties.

Powerful enemies surround him from without, while treacherous ministers undermine the nation from within. It's a disastrous start from the start.

Fortunately, he awakens the [Immortal Kingdom Cashback System]. Any resources he spends are returned tenfold!

The stronger his immortal kingdom becomes, the stronger he becomes!

Thus, Wu Yu ushers in an era of cultivation for all.

Others struggle to get spirit stones, but he can use as many as he wants, so long as he can spend them!

He can gulp down any pill he likes, so long as he can spend it!

He can use the spirit liquid from secret realms to water his fields, so long as he can spend it!

His immortal kingdom has only one rule: use as many resources as you can. Be extravagantly rich without a shred of restraint!

With the System's help, an immortal kingdom destined to endure for all eternity rises.

Many years later, Wu Yu, now possessing an immortal and indestructible holy body, gazes at the boundless ranks of immortal soldiers and generals in the distance, then turns to look at a sacred statue in the sky:

“You don't even have an immortal kingdom, and you still dare call yourself an Immortal Emperor?”
