Li Changan traveled through time.
On the first day he traveled to the world of immortality, he was bound to a takeout delivery system.
Delivering meals will increase your cultivation level, good reviews will increase your mana, overtime will deduct your realm, and negative reviews will directly deduct your doubts about life.
"Would you travel back in time with me and be a food delivery guy?"
But after working as a gold medal rider for three years, he soon discovered that riders in the world of immortality were much better than in his previous life.
Sect boss ordering takeout? Deliver! Monsters and beasts blocking the road? Hide! The system wants to mess with him? Then turn around and pluck out the system's wool!
All the way from the food delivery boy in the qi training stage, to the webmaster in the Nascent Soul stage, and then to the tribulation stage...
While all forces were tracking down the mysterious entity that was stirring up the world of immortality, Li Changan was sending a message to his last customer:
"Dear, your elixir has been delivered, please remember to give it a five-star rating~"
