Siheyuan starts from upgrading skills

An ordinary college student, Yi Guoqu, passed through the courtyard and almost starved to death. With the living allowance given by the system, he ate his fill and began living in the courtyard.

He entered the factory to work under the recommendation of an old man. At the same time, he discovered that the system had many survival skills that could be upgraded. He began to use these skills to climb and struggle in that era.
