Cang Lu tried to escape Bi Lin's clutches a few times but ended up being blocked by Bi Lin who had used various Thunder Beast secret techniques. Thunder Beasts had powerful Psyches. Their physical body was their weak point. However, Bi Lin was protected by the Purple Demon Armor, so she did not need to fear Cang Lu at all.

In the end, what else could Ye Chen and Little Wingsy do other than obediently hand over the Cosmic Stones they had collected to her?
