In All the Worlds, I Am Just a Courier!

(Travel + Infinity + Funny + Invincible + Express + System) When other people travel through time, they either become immortals or seek hegemony. Lin Xiao traveled through time and bound to the Zhutian Express System. After sending Journey to the West, I will send you the prehistoric world, and after sending Cultivation, I will send you sci-fi. The Immortal Emperor kneels down to welcome you? Demon Lord gives way? Did the Lord God personally sign for it? Lin Xiao looked helpless: "Please hurry up, I'll deliver the next order in a hurry." "I'm really just a courier!"
