Hearing that Hong Dali was giving out smartphones, everyone there all came up.
Hong Dali was thoughtful. For the last 20 plus smartphones that he assembled, he didn't use the best perfect-grade parts to match them together. The main ones he used were the pressure resistant, super strong reception and a battery capacity that was three times that of a normal phone.
After all, it was enough for himself to know about his skill. If he used the best parts for all of the smartphones, it would cause people to become suspicious. If that happened, It wouldn't be a good thing for both him and others—the System was his greatest secret, it definitely must not be known by anyone else. If not, it wouldn't be good if he was sent to a laboratory and cut-up like a guinea pig.
