What kind of weapon did Wei WuXian use after he was offered up? Was he still casually making a confession?
According to the plot of the novel, the sword that Wei WuXian used after he was offered up was called the 'Frosty Winding River'. This sword belonged to the East Ocean Dragon Clan. It used to belong to a famous swordsman. Later, for some reason, the Dragon King of the East Ocean gifted it to Wei WuXian. After Wei WuXian was sacrificed, this sword became his soul weapon, helping him protect himself and others in the soul world. As for Suiyi and Chen Qing, these weren't the weapons that Wei WuXian used after he was offered up. In the novel, after Wei WuXian was sacrificed, his soul left his body and entered a space similar to an illusion. In this illusion, he could use some special techniques and tools to protect himself and others. Both Sui Yi and Chen Qing were commonly used props in this illusion, which could help Wei WuXian with all kinds of magic attacks and defenses.
