Narrator: In this world, Lü Bu did not meet his end in defeat at the hands of Cao Cao. Instead, he followed Chen Gong's stratagems, defeated all the heroes and mighty warriors across the realm, and seized control of Chang'an. With his next target set on the continent of Teyvat—home to seven nations and hundreds of heroes—Lü Bu resolved to march there with his subordinates, including Gao Shun of the Trapped Camp, Zhang Liao, Chen Gong, Wei Xu, and others, as well as his allies Yuan Shao and Yuan Shu, to conquer Teyvat in unison. At this moment, the scheme was discovered by an immortal named He Jinzhe, who immediately traveled through time and space to Teyvat to warn the Traveler. Can they prevail against Lü Bu?
Lü Bu: I'm utterly bored. It's high time I headed to Teyvat to spar with the warriors of the seven nations.
Chen Gong: My lord Lü Bu! (shouting loudly) The Moonlight Treasure Box-brand spacetime shuttle is ready for full activation! (excitedly operating the machine)
Lü Bu: Yuan Shao, Yuan Shu, Gao Shun, Zhang Liao, Chen Gong, and all the rest of my soldiers and generals! Come forth! The hour has come for me to unleash my might! (The armies of Lü Bu, Yuan Shao, and Yuan Shu filed into the spacetime machine, and they vanished moments later—a sign that their crossing had succeeded.)
Unbeknownst to them, every detail of their plan had been witnessed by a Liyue mage named He Chizhe.
He Chizhe: I must join forces with the Traveler and the people of Teyvat to foil Lü Bu's plot.
He then used the Moonlight Treasure Box-brand shuttle to cross over to Teyvat and set out to find the Traveler. He searched endlessly, and at long last, he found Aether and Paimon resting beneath a great tree. He Chizhe revealed Lü Bu's scheme to the Traveler.
He Chizhe: I've come bearing terrible news! A fierce warrior named Lü Bu has crossed into this realm with his followers and allies, intent on conquering Teyvat!
Traveler Aether: What?! Who is this Lü Bu to speak such arrogant words?
He Chizhe: Lü Bu hails from the Eastern Han Dynasty. He is tall and powerfully built, wielding the Sky Piercer halberd and riding the Red Hare, a steed that can travel a thousand li in a single day. There is a famous saying about him: "Among men, Lü Bu; among steeds, the Red Hare." He once defeated three mighty generals of the Shu Kingdom at the Battle of Hulao Pass! At Chang'an, his feats were even more astounding—he crushed every hero and champion under heaven.
Traveler Aether: Ah! He is that formidable? Rest assured, though—I have many powerful warriors who are also my dear friends, and they will defend the peace of Teyvat. Speaking of which, which nation's heroes do you think Lü Bu will challenge first?
He Chizhe: I cannot say for certain, but he declared that he will subjugate every nation here and declare himself emperor, ruling over all.
Traveler Aether: Ah! What colossal ambition, what unbridled arrogance! Then how can we track where Lü Bu is heading?
He Chizhe scratched his head and said: Well, the thing is…
Just as they were puzzling over how to uncover Lü Bu's next move, they spotted an army approaching from the cliffside. The soldiers' uniforms resembled those of Liyue, yet were distinctly different. He Chizhe and Aether moved forward to investigate, while Paimon raised a spyglass to her eye.
Paimon: That warrior on the red steed, wielding a trident-like weapon… Could that be the fearsome Lü Bu you spoke of?
He Chizhe took the spyglass from Paimon, glanced through it, and said: Yes, that is him, without a doubt!
Traveler Aether: It looks like he's heading toward Mondstadt. We can't let him get away with this! Let's hurry there at once to alert the people and soldiers of Mondstadt, and get them ready to mount a defense.
