Capítulo 291: Collapse of the Ladros City: [Descent of the Binding Apostle]

Souta looked at the barrier as he tightly knitted his brows. He wondered if there were teachers who could forcibly shatter the barrier in the control room as most of the teachers left to fight the Seven Deadly Sins.

From his quest, he knew that someone stole the barrier device inside the control room. Surely, the people who stole the device already left but he still wanted to find some clue inside the room.

The Seven Deadly Sins wouldn't do things like this. If they were going to snatch the bloodstone they would simply snatch it while killing everyone who got in their way. They wouldn't activate the barrier device.

Also, from the information of the quest, he could guess that there's another organization here besides the Seven Deadly Sins.

'Jeanne, Wako, and Yanagi are here.' Souta thought as he rubbed his chin. He could get Yanagi here to shatter the barrier but she was uncontrollable.
