Xia Xuan glanced at the metal shop behind Bai Qi, suddenly thought of something, and asked, "Have you reached the second stage?"
Oh my god, this guy is too sharp, he can even figure this out?
Bai Qi glanced at the second Rune Mark that he still kept hidden, unsure where he had given himself away.
"As a mechanical warfare student, you naturally chose the Mechanical Engineering Department, and coming to Jiuding Mall to buy materials shows your good taste."
Xia Xuan seemed quite pleased with Bai Qi's expression, and continued, "Just so happens, I have also just broken through to the second stage, you can accompany me for another round."
So it was just a wild guess...
But it didn't matter, anyway, he no longer needed to keep it a secret after he attempted the second tower.
Bai Qi sighed resignedly and said, "Sorry, I'm in a rush, I don't have time to play with you."
