If you are asking about the waste gas storage in my world, you should look underground. For example, enter the seed (mobile phone version) Mimi into the well and dig it to the end to find it.

If you want to find the last relic, you must kill the last shadow man to get the last shadow bead, and then go to hell to fight the flame stick, smash the flame stick into flame powder, and combine it with the last shadow bead to form the last shadow eye. Right-click the last shadow eye in the field, and it will fly in the direction of the last relic. You can use this to find the relic.

Then look carefully and find a portal parallel to the ground. Put the eye of the last shadow in a circle of green boxes around the portal, and the portal can be opened, leading to the last shadow world, where there are many last shadow people and last shadow dragons. You can gain a lot of experience by killing Shadow Dragon.

The way to find the library seeds for my Netease mobile version is as follows: first, start my Netease mobile version, open the game and enter the game world. Secondly, create new games or enter existing games to find villages or relics. You can start exploring the map and look for nearby villages or ruins.

My world dungeon library is on the 68th floor. According to the relevant information, you can shoot all the disappeared people, disappear their eyes, fly into the sky and follow the disappeared eyes. One is enough.
