I Was Picked Up by Elysia

I only wanted to take care of some everyday chores, but somehow I missed a step and fell into this world.

When I opened my eyes again, I saw a cute girl who introduced herself as Elysia.

To figure out what world he had transmigrated into, Su Qing set out on a journey with her after the two had gotten to know each other.

Then came the disaster known as Honkai, and the First Herrscher, the Herrscher of Reason, appeared.

Wait a second, the Herrscher of Reason isn't Yang "Sit-Up"?
