I Run a Train in Honkai: Star Rail, and All of Teyvat Is in an Uproar

[Honkai: Star Rail + Honkai: Star Rail + Genshin Impact + Invincible Power Fantasy]

Su Chen transmigrates to the Underworld of Belobog in Honkai: Star Rail, and gets his own Astral Express as a reward from the start!

As long as he helps residents from other worlds embark on their Paths, he can grow infinitely stronger.

Just then, a Teyvat chat group appears, right as Mondstadt faces a dragon disaster!

To bring supplies to the Underworld, Su Chen floors it and tears through space. From the start, he drives the Astral Express straight into the Stormterror, sending it flying over a hundred meters with a deafening crash!

Facing the dragon's rampaging breath, Su Chen wields a Preservation lance and unleashes “Ever-Burning Amber,” transforming it into an absolute defense!

When the people of Teyvat see a golden shield sturdier than bedrock, the whole world goes wild!

Ningguang: “A spear wreathed in golden light, steady as a mountain. This must be my lord Rex Lapis traveling incognito!”

Yae Miko: “My, my, with a shield that sturdy, who else could it be but that old gentleman from Liyue?”

Ei: “A mortal can wield power that surpasses the Vision?!”

Su Chen surveys the crowd with a smile. “The Vision has its limits. My train travels the vast sea of stars! Those who board will be granted an Aeon's Path and power to rival the ancient gods!”

Lumine and Diluc scramble to get aboard, and the whole of Teyvat is swept up in a frenzy over the Astral Express!
