After entering the area with the grapevines, things became much easier for Han Sen.
The fighting skills that the four Chaos employed were rather simple and a little clumsy, but they weren't weak. One versus one, Han Sen might win. But against four of them at the same time, there was a high chance he could stumble and fall.
Han Sen used all the judgment, prediction, and movement that his skills gave him. He did this so he could fight them more effectively in the grapevine area.
Han Sen kept escaping in the direction that Yisha had fled. But Yisha herself was now headed in the direction Mister Ji had gone, so Han Sen was unable to see her. If she had not been killed, she should still be in the grape area.
Han Sen was still curious about how she had managed to get rid of the Chaos that were chasing her.
