Meng Xin asked for help. Shima Sakon (dlc3, like some mysterious soldier) in Wang Ren 2 prison can't rub his back for a few seconds. How to fight?

Then I, a crippled party, tried a fake back rub myself. Personally, I think it is quite useful for people with disabled hands.

It's probably a simple scrape with a horse (he just released the guardian spirit/fell from the sky/had the biggest flaw), then cut the cross twice, quickly get out of the way and repeat the process.

I hope I can help you. If you don't know anything else, you can see the link here.
