After leaving Fangling Hall, Angel arrived at the Infinite Battle Tower.
Angel had originally intended to bid farewell to Serum.
However, to his surprise, when he arrived, according to the battle schedule, Serum was still in a match.
Having spent some time in the development institute and then so long at Fangling Hall, could it be that Serum's sixth-floor promotion match still hadn't ended?
It was only upon closer inspection that Angel discovered Serum's current match wasn't a sixth-floor promotion match at all, but had already reached the seventh floor of the Infinite Battle Tower.
Filled with curiosity, Angel wondered if Serum was fighting back-to-back matches. Yet even more baffling to him was why this seventh-floor match was an open spectator event?!
