So, you think that we can absolutely take BJ and yet you think that if we used the skill he has hidden neigong reserves he hasn't accessed that he could use to screw us over? Why not use that to crush us?
He already said what his intention was.
If he has that extra neigong hidden somewhere up his ass, he's going to use that to beat Jing down so that he can proceed with interrogation. A2 is a terrible choice; it pisses him off with our continued resistance, we'll almost certainly lose the fight (this definitely doesn't look to be one of those fights where we can scrape by without giving our all, and as to using our fancy Japanese sword techniques of a better skill level... we've tried that, most of it ended up countered because he's probably a full skill level better than even our best sword moves) and get interrogated, and we don't even get to train the Wuxian Qiankun skill for the trouble. This is very important to him, he's not going to be toying with us.
If you don't want him to find out the skill then you should take one of the options to run off; who knows if that'll actually work given how speedy this guy is, but if we're able to stray out of his sight for one moment our stealth will probably give us a decent chance of getting out of here. Staying here to fight is a bad idea unless we're willing to commit all the way.

“Are you going to try and make me talk?”
“I cannot afford not to. My shimu already suspects a thing or two about you… even if you do not talk now, you are merely postponing the inevitable.”

You lash out with your fist, but with a twirl he steps away from it, calling out to you, “You are not yet using everything you have, are you?”
[...]
You land a safer distance away from him and sheathe your wodao. Giving him a casual smirk, you ask, “Do you think I need to use everything I have?”
“I will make you use everything you have. You are not leaving this mountain otherwise, Xu Jing,” comes the reply.
