The Happiness System, but Its Host Is Uchiha

Tan Xiao transmigrated.

But she turned into a bamboo shoot.

The good news: she has a System.

The bad news: she's the System, and she's about to become a [Happiness Value System] in a place where the world is in chaos and everyone is born into a living hell.

The even worse news: the person she's bound to is a man who will stir up bloody storms in the Warring States era. If she wants to become human again, she has to accumulate happiness points so she can escape her bamboo-shoot body and regain her human form.

Fortunately, there's still a chance. So she puts on the secret identity of the "Goddess of Happiness," invents a conspiracy theory about a mastermind behind the scenes, and convinces the ninja that someone deliberately caused their centuries of suffering. Then she uses her familiar tricks of persuasion, max-level rhetoric, and gacha items to get the ninjas working hard to collect happiness points.

But before her best tricks, such as combat tactics, matrix strategies, and closed-loop schemes, can even take effect, she hears...

Refugee A: "Oh my gosh! We get a full meal and water for working twelve hours, and we don't have to worry about getting hacked to death by soldiers. How is that not happiness?!"

Refugee B: "The lord gives me food and a place to live, and even treats my illness. Sure, I have to test medicine, but this is practically heaven! My happiness value is through the roof!"

Defeated ninja: "The whole clan came out and nobody got killed. Sob! Lord Uchiha/Senju is a living bodhisattva!"

Tan Xiao, listening to hellish statements while her happiness points shoot up: "...Stop being happy, you're scaring me.jpg"

Even Satan would have to admit he was an amateur.

But what can she do? She still has to collect happiness points.

A hellish joke is still a joke.

And happiness points from hell still count as happiness points, don't they?

Thanks to Tan Xiao's hard work, the style of the ninja world... finally went completely off the rails.

Uchiha Madara became the "cold-faced, kind-hearted living bodhisattva of the ninja world."

Senju Hashirama became the ninja world's god of agriculture.

Senju Tobirama watched people who were grateful to him come forward to cooperate, and began questioning his life.

Uchiha Izuna had only just been revived when he saw a group of ninjas singing and dancing around an elaborately decorated bamboo shoot as they held a ceremony. Even his elder brother and mortal enemy looked solemn and serious. Izuna: ...

Wait, he'd only been dead for a little while... Had he somehow ended up in a different world?

Later, Black Zetsu appeared and tried to set the Infinite Tsukuyomi in motion.

Before Tan Xiao could do anything, the ninjas shouted, "We've found the mastermind!" and charged at him.

In the end, her wonderful Host decided to bring his good friend along and help her fight their way through the universe to reclaim "everything she'd lost."

Including, but not limited to, her status, position, and authority as the "goddess of the Otsutsuki clan."

Tan Xiao panicked. Wait, there really are other planets in this world? And there really are goddesses on those planets too???

Help! Can someone stop these ninjas from charging into space?!
