I, the Immortal, Am Invincible to Billions of Points. It Makes Sense, Right?

Ling Chen is an immortal and the owner of a mysterious grocery store. The grocery store sells everything! The ancient human emperor bought the first ray of fire in the world from there and allowed the human race to rise. The Lord of the Underworld bought a model toy from there and established the Six Paths of Reincarnation. All gods and Buddhas hope to walk into that shop and complete a transaction. He watched with cold eyes the changes of dynasties, the rise and fall of families, the twilight of heroes, the bones of beauties, and walked around the world with a grocery store.
