I spread immortality all over the world

Read manhua I spread immortality all over the world:

“Pow! Ten more years will pass before the monsters are back.” Su Yang looked quite serious as he listened to the voice in his ear. He was aware that the earth was now populated entirely by common people, but that there were still ten years until the monsters arrived. It is impossible to bind chickens. After ten years, humans are utterly powerless to stop demons from rising again. Thankfully, his activation of the system read, “Popularize the method of cultivating immortals to the whole world!” He set up a little store and marketed different techniques for creating immortals. “Tathagata God’s Palm” , “Prajna Divine Art” , “Red Dust Sword Jue” … Additionally, the business offers a variety of elixirs, including the “Building Foundation Pill,” “Longevity Pill,” and “Sura Pill.” Innumerable carved formations, such as “Big Zhou Tianzhen,” “Little Star Douzhen,” and “Eighteen Arhats,” are also sold in the store. The important thing to remember is that his business is empty!
