Xia Liu didn't get to imagine for long before Bai Shixiong took out a completely white jade block and threw it towards the giant tower.
The jade block floated slowly in front of the stone gate of the giant tower, like a spirit.
Humming...
As the jade block started to emit a faint light, a low chanting sound came from the giant tower.
Soon after, the huge stone gate rose without any apparent cause.
As the gate of the giant tower opened, a desolate and distant aura emanated from within.
Such a change came as a surprise only to a few low-rank warriors, while the others were already accustomed to it.
Just as Xia Liu was about to enter first, Bai Shixiong stopped him, "To enter the Library Pavilion, one must increase energy; otherwise, you will encounter resistance."
Xia Liu said nothing, looking towards Zhang Xiantian and Sun Mingcong.
They had both rested for a night and had recovered somewhat, all because Xia Liu had held back during the contest in the arena.
