The first layer: Bei A Duo deceived the warriors and won their sympathy. In fact, the master is also on Mr A Duo's side. The man who helped the war just wanted to trick him into signing the contract.
However, according to the first floor, why did Mr. A Duo couldn't help it at the last minute? This is totally unreasonable.
The second layer: In fact, what Bei A Duo himself wants is not an absolute hostile relationship with the combatants, but a peaceful debate with them. Just as there are some expectations for the life of EP4, there are some people in northern A Duo who want to "play" Zhan Ren forever in this world. However, Bei A Duo has a more important purpose (just like Yuan Shou has the purpose of saving the war man back), and she can't give up that purpose for a moment's fun. This is the ambivalence of Bei A Duo. And master craftsman, also know Mr A Duo this kind of mood.
At the last moment of signing, the master hacked first. I know you don't want this ending. You have more important goals. Since you can't make up your mind, I will help you. If you don't pretend to be a bad guy now, I promise you will regret it later. "Mr. A Duo understood this meaning, so he went into the dark and told the soldier that he had lied to the soldier before. But in fact, this sentence is deceptive, and the appearance of shyness before is also the sincerity of Bei A Duo.
