• Azer explained that he and the lance were too weak to defeat Great Red now but could grow strong enough in the future.
• Ophis believed Azer and raised her hand, gathering power in the shape of a black snake to give him.

Ophis offered Azer a snake containing nearly one-tenth of her power to help him defeat Great Red, and Azer accepted it without swallowing it. After Ophis disappeared, Azer resolved to accelerate his efforts to grow stronger.

• Ophis presented Azer with a snake holding nearly one-tenth of her power and asked him to help defeat Great Red.

• Cao Cao explained that the Hero Faction was recruiting talented humans to preserve humanity’s strength and prepare to challenge the mythological factions, and Azer accepted the mission.
• Azer returned to Kuoh Town using Georg’s concealment array and found that the hotel had sold off his luggage after he vanished for a week.
