I think it's chinese. The only thing I remember is that the mc is kinda afraid of his landlord lady and he repairs her VR pod with one of his friends who works as a repairman with his father and gets a few months of free rent as a reward.
I know what scene you are talking about but I cannot remember the novel either. Edit: I remember it now. It was "Legend of the Gunslinger Mage", an original novel on Webnovel.
