Cultivation of Immortality: Starting from Breaking into the Sword Tomb

I have thousands of flying knives, and I dare to fight the three realms to kill the immortals! I have a supermarket where I can buy unlimited mana! Practice? Just kidding, I will never be able to practice in this life. Have you ever visited Shengxian Supermarket? When I have the spiritual stone, I will buy the cultivation level. If the foundation building stage is not enough, I will buy the golden elixir stage. If the golden elixir stage is not enough, I will buy the Nascent Soul stage! Sooner or later, one day I can use the spirit stone to hit the tribulation stage, or even higher! There are only two words in my mind - make money! Remember, I have the compound surname Qi Guan, and my single name has only one character, which is very good!
