The Useless Spirit Root Counterattacked and Became a Lifetime Boss

Shen Tang traveled through the world of immortality, but became a pitiful little useless person who was despised by everyone. His spiritual power collapsed and his life was in danger. She originally thought that she could only use up her last bit of strength to wait for death in misery, but the torrent of memories from modern times opened up a glimmer of hope for her - elixirs, talismans, magic weapons and spiritual materials. Why can't she do some "promotion"? "Tangtang Xiuxian Department Store Supermarket" is now open! Buy ten and get one free, members get discounts, and limited edition blind box sales are available at the opening! The low price and unheard-of sales model instantly swept the low-level monk circle. The geniuses of various factions fought hard to grab membership discounts, and the aloof Immortal Lord queued up late at night to wield a sword just to get a hidden money. When the demon king came to the door with the entire spiritual vein and demanded a year-round VIP package, Shen Tang thought that his business territory had reached its peak. She handed over the contract with a smile: "Dear, if you recharge, you will get a free gift——" But she saw the demon lord's scorching gaze penetrating through the spiritual stones and magic weapons and locking on her: "The gift I want is you."
