Chapter 251: Chapter 252 Maintainer I Was Going to Study the Universe Aircraft

Jack felt proud at the thought that all these belonged to him.

At the thought of the construction of Mechanical Giant City, Jack found that Maintainer I hadn't shown up in front of him for a long time, so he asked, "Do you know what your brother, Maintainer I, has been busy with recently? He hasn't shown up for a long time."
