Why was Zhang driven out of Longhu Mountain by one person?

Speaking of Zhang, a junior teacher of abstinence department, everyone will think that this product may betray his legacy and be driven out of Longhu Mountain. But the fact is so cruel that Zhang fell to the street to tell fortune. What's going on here?

For the sake of his sweetheart, Zhang teamed up with Miao and Xia He, the scraping knife, to fight against those who were allowed to help touts eradicate the whole sex. So I have to say that Uncle Xiao is still very enterprising. Zhang really paid too much for Xiahe.

That's the case, but there are some doubts. First of all, old Shi Tian went down the mountain not to eradicate the whole nature, but to find Gong Qing, the head of the whole nature, and to seal the secret. Moreover, when he went down the mountain, he only took one apprentice, never making moves, and Dont Ask For Help helped him. So it's hard to say who these people are who help touts eradicate the whole nature and what their purpose is.

It is obvious to all that Lao cultivated Zhang. Among the top ten disciples, Lao can be said to be Zhang's most valued. He inherited Leifa since he was a child, because he was gifted. Although he lost his body, he could only use dirty tricks and thunderbolts, but he was honest and always led him to lose the game, but Zhang didn't complain. He's still thinking about master, and he believes it.

On the surface, Zhang was accused of colluding with the whole demon, but he was driven down the mountain probably because God asked him to help him find out the secret of the rebellion, which was just a superficial reason.
