After the First Guide and the Villainous Sentinel Switched Bodies

One morning, SSS-rank Guide Lu Yansheng and SSS-rank Sentinel Su Yechen switched bodies.

In enemy territory, wearing Su Yechen's face, Lu Yansheng pieced together what was going on:

1. He had become the adopted son of his father's sworn enemy.

2. His father's sworn enemy had loved his dad without ever winning his heart. He planned to have his adopted son kill Lu Yansheng's father, then marry his dad and become his stepfather.

3. He had to fight alien species every day. But his mighty SSS-rank combat-type spirit form, the Flying White Tiger, had turned into a little white rabbit that could only act cute...

So here's the question: What should he do?

*

Recently, the teachers and students at the Empire's First Higher Military Academy noticed that Lu Yansheng, once the top Guide student with perfect scores in every subject and a kind disposition, had not only scored zero in his mental-guidance class, but had also become cold and distant.

Then Su Yechen appeared. He was a year below Lu Yansheng, had not shown his face on campus since the semester began, and still held the top spot on the Sentinel Academy's points leaderboard by an overwhelming margin...

*

Lu Yansheng thinks his roommate Su Yechen might have a split personality and amnesia.

Cold and distant by day: “Stay away from me.”

Clingy by night: “I can't sleep unless I'm holding you.”

*

Su Yechen has a white moonlight in his heart named Lu Yansheng.

But he is the dark Sentinel from the Book of Prophecy, the one destined to destroy the world, the embodiment of disaster.

He wants to stay away from him. He just never expected them to switch bodies.

Even more unexpected, his obsession with Lu Yansheng had already caused a second personality to emerge.

*

Later, Lu Yansheng and Su Yechen switch bodies several more times.

Later, Su Yechen's identity as a dark Sentinel is exposed, and terrified people across the interstellar empire demand that he be executed.

Su Yechen: “Are you here to kill me?”

Lu Yansheng: “Kill you? Let's run away together.”

*

Later still, the apocalypse arrives, alien species overrun everything, and an unknown civilization invades.

A flood of ancient memories pours into Lu Yansheng's mind...

It turns out he is the villainous final boss who will destroy the world.

Interstellar Stray Animal Sanctuary

At noon, Su Yechen sits on a bench beneath the courtyard pavilion, reading. Lu Yansheng rests his head on Su Yechen's lap, holding a sleeping panda cub, while rolling a little black ball in his hand.

Lu Yansheng: “Your spirit form doesn't feel all that great~” That's what you get for always petting my white rabbit spirit form. Now you're in my hands~

Su Yechen: “Of course it doesn't compare to how soft and adorable you are, my dear.”

Lu Yansheng: “!?” Keep talking, and I'll throw this stupid ball away!

A cherished imperial love story: His Majesty and General Lu are devoted to each other, perfectly in tune~
