Dogs bite Lv Dongbin and don't know the origin of good people;
When Lv Dongbin became a monk for the first time, Zhong Liquan gave him a mixed gossip cassock to wear. This robe is not afraid of fire and water, nor of swords and soldiers. But it happened that the first enemy I met was Jiro's roaring dog. This dog is not like an ordinary beast. He has been practicing hard since ancient times. Although he did not become a fairy road, he also became an invulnerable body.
Its teeth, honed and forged for thousands of years, have made a lot of contributions with its owner and killed many monsters. Naturally, its biting power is ten times stronger than that of ordinary sword soldiers. Besides, at that time, Lv Dongbin was bent on saving it. How could he stop it from drawing a circle when it was dizzy and hating the enemy in his heart?
What is even more unexpected is that Dong Bin started painting to save his life. He just thinks everyone in this school is its enemy. How could he run out of such a savior for no reason? So, while drawing, don't ask how to draw. Whoever is holding this painting. In order to get revenge and escape, it had to bite him desperately.
Dong Bin's cassock can only resist ordinary fire and water soldiers, but it can't resist the teeth of the roaring dog. Inadvertently, it suddenly took a bite and bit on the calf. Nature is the last straw, make a hullabaloo about, swoon.
