The more he cultivated into the immortal world, Lin Shi started on the Hell Difficulty - the lowest level servant of the Qingyun Sect, with a mediocre spirit, and was ridiculed by the genius. Just when he was showing off his junk, the [Trash Recycling System of All Heavens] was activated! The broken, old, and abandoned things in the world are all upgraded to treasures, and you can also see the true inner barrage above everyone's head. Chu Tianjiao, the genius of the sect, is engaged in hard training every day, and all the splendid immortal weapons are defective. Every time he pretends to be fake, he will die on the spot; Lin Shi was too lazy to meditate, so he picked up the rags left over from fights in martial arts arenas and secret battlefields, and his cultivation quietly crushed the entire sect. After the system unlocked the passage to the heavens, the Demon Lord from the Demon Realm carried a sack of damaged magic weapons across the border to seek trade, and the Immortal Lord from the Immortal Realm climbed over the wall overnight and queued up to exchange for elixirs. The two supreme beings fought over the rags and demolished the shop, leaving them to sweep the floor and sort the scraps to pay off the debt. Later, ancient remnants, fragments of heaven, and abandoned remnants of the universe were constantly delivered to the door, and the creation bosses from all walks of life rushed to please him.

Although he can control the power of all realms, Lin Shi just wants to wait in the secondhand shop to bask in the sun, pick up rags and eat melons. The Supreme Immortals and Demons take turns doing odd jobs, and the former Juan Wang Tianjiao's mentality has completely collapsed. This is a novel about cultivating immortals with no cruelty in the whole process, funny contrasts, and an invincible level of success!
