Superdimensional Express: First Delivery Costs a Billion

After losing his job, Wang Hong becomes an employee of a spacetime delivery platform, only to discover that the packages he has to deliver are bizarre beyond belief.

[Within three days, deliver package Jiazi 1568124140008, Gundam: War Demon God, to Li Shimin before the fourth day of the sixth month in the ninth year of Wude under Emperor Gaozu of Tang. Reward: one billion.]

[Within two days, go to Shanzhong in the fifteenth year of Tianbao to pick up Li Bai, then take him to Mount Lu to receive package Gengchen 2515145571000, the Immortal Art Green Lotus Sword Song. Reward: a random supernatural ability.]

[Within five days, pick up Liu Bei before the Guisi day of the fourth month in the third year of Zhangwu, then take him to Chengdu to receive package Yichou 145825474777, the Dao Artifact Heavenly Edict of Civilization. Reward: one treasure chest.]

Ever since joining the Special Affairs Investigation Bureau, Li Changxi's worldview has been shattered beyond repair.

What on earth are these travelers from the multiverse?

That woman over there claims to be a princess of the Tang dynasty and looks exactly like me. She says Emperor Taizong Li Shimin piloted a Gundam to unify the world.

The woman over there claims to be a disciple of the Green Lotus Sword Sect and also looks exactly like me. Her story is even more absurd: the Immortal Sage of the Green Lotus, Li Bai, received the Way from an immortal, spread its teachings among all living beings, and ascended to heaven in a radiant glow.

Aaaah! When did this world get so crazy?

Wait, what are all of you doing in my world?

What do you mean the schemer who changes the multiverse, the ultimate boss controlling the multiverse, the great demon king known as the Ultimate Terror, is in my world?!
