When was the tomb opened?

The conditions for opening and closing the library are as follows:

Opening conditions:

Rule 1: You must use your own roots to open the library, that is, you can get what is in the tomb (or in the library), otherwise you can't get it.

Article 2: before it is too big, it must be used to open the library. For example, on Chen Jiari, the Lord must open the library with a seal. When you open the library, you must have a good line, because Lu can seal it, otherwise there will be disaster.

The ground is ugly, and Chen Shuchong is opening the museum; Tianganchong can also open a library; The Universiade opened the warehouse.

Conditions for closing the library:

Fate may form a trinity with the Universiade, that is, Shen, Hai and four friends are ugly and comfortable; Or form three meetings, namely Yin, No.3 noon and Shen Youshu; There may be mixed situations, that is, ugly children are mixed with soil, fire and soil are not mixed at noon, fire is mixed at night, and gold is mixed at night. In all these cases, the tomb will be closed and its function will be lost. The five behaviors of integration, communication and culture prefer to use closed libraries, but they don't like closed libraries when avoiding them.
