Treating Three Mad Princes at Once

Madman No. 1 is cool and aloof, an Immortal Venerable who loves no one. He follows the immortal sect's rules to the letter, without the slightest trace of human compassion. He wants to turn all three realms into a world of meat-free nuns and monks.

Madman No. 2 is a wicked, arrogant tyrant of the demon realm who has people's heads chopped off for fun whenever he's in a bad mood. He's a libertine, and his goal is to open a brothel across all three realms.

Madman No. 3 is a seemingly sweet but secretly sinister young master of the demon dragons, on a path of revenge. As he pursues vengeance, he grows increasingly twisted inside, yet looks more and more innocent and pitiful on the outside: a plump little black-sesame rice ball.

If no one keeps them in check, all three realms are doomed to become victims all over again.

System: "So you need to bring the aloof Immortal Venerable down from his pedestal, make the libertine Demon Lord a lovesick fool, and get the young master of the demon dragons to let go of his hatred, before he gets even more corrupted!"

Yun Li: "Why did you pick me?"

System: "Because you're a medicinal plant in the mountains that cures every disease!"

Yun Li: "=.= Wow, I can do that?"

With the belief that everyone is responsible for the fate of the world, Yun Li got to work. But once their treatment was complete, events took a sharp turn for the worse.

The Immortal Venerable pulled her into his arms and asked in a trembling voice, "Xiao Li, I've descended into the mortal world just as you wished. Why are you running away?"

The Demon Lord pinched her chin, a dangerous smile on his lips. "Lili, you're going to have to explain the meaning of 'one partner for life' to me all over again."

The young master of the demon dragons held her close, burying his face in the crook of her neck as he murmured, "Yun Li, from now on, you have only me. Hold on tight to me."

Yun Li: "Oh my goodness! Why are they still fighting!?"

System: "Ahem, actually, they've already been fighting behind your back several times..."

A love rivalry erupts in the harem.

Since you can't marry them all, and you can't marry none of them, then arrange the marriages one by one, in a nice orderly line~

Theme: Love and peace. Don't fight
