The Apocalypse Is Coming, I Sold the Blind Box and the Spiritual Energy Was Revived?

Jiang Heng travels through the parallel world and knows in advance that high-powered monsters will invade Blue Star one month later. However, the system that Jiang Heng awakened turned out to be just a 'random blind box system', which could produce exquisite small pendants at the lower limit, rare spiritual pets, immortal cultivation techniques, and peerless magic weapons at the upper limit! No matter what item the customer purchases, the reward will be returned at a hundredfold increase! "Boss, you are so dark-hearted. You want to sell me a broken sword for 500,000 yuan? Do you believe I should call the police?" "Miss, first of all, this is not a broken sword, this is a top-quality flying sword..." "Then why did a water-breeding tortoise appear in the blind box?" "That's wrong. This is Squirtle. It's not called Zishui Bastard. It's a rare divine pet from ancient times..." "What the hell is the secret book of the technique for turning fighting spirit into a horse?" "I said I can cultivate immortality, do you believe it?" A month later, the plane creatures invaded. But when they saw everyone flying with their swords, moving mountains and seas, and opening the gates of heaven with just one sword... Scared to the point of peeing. "The Blue Star people are too dangerous, I want to go back to my hometown!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
