Chen Xin is not one to procrastinate; he and Qin Lan went straight from the train station to the "Drilling Expert's" home, intending to ask him for help in drilling a deep geothermal well to construct an Energy Tower.
The "Drilling Expert's" home is located at the foot of a mountain in the suburbs, and due to its location, the snow here is not that deep and has been cleared, allowing Chen Xin to see that this place was originally a courtyard akin to a small factory.
The courtyard and factory seem abandoned, but the snow has been cleared to allow Chen Xin and Qin Lan to enter from outside and see the clearly added protective gate in the courtyard.
Behind the protective gate might be the "Drilling Expert's" shelter; it appears that, like Chen Xin, he opted to dig a living space into the mountain, effectively utilizing the mountain as a protective layer for the shelter.
