When the cultivation value reaches more than 2000, the system will prompt you to take a rotating photo. Go to the foot of Wanzhong Mountain, where there is an ethereal place. Do related tasks to get the Inner elixir for rotating photos of pets. When the cultivation value reaches more than 8000, the system will prompt you to turn on the light. Continue to do the tasks related to the ethereal land, and you can get the inner opening elixir. I don't know if I haven't done it since. The repair cost of more than 8000 yuan is expensive and unnecessary.
