Still half asleep, in his instant reflexes, he launched multiple knives at the lady. In a split second, she dodged most of those except the last knife when Yu Ping intercepted. He was caught off guard and was unable to read the mister's sleep walking movement. When it registered, he managed to rush in and deflected the last knife.
When someone act without evil intention and acted purely based on no thoughts and motives, it can be hard to be cautious against them. People's motives are often felt by the vibes they give off, but the mister's intention was done so in his sleep when his mind was blank. So, when Yu Ping caught on, he moved in to help the lady. It wasn't until moments later that he realized she managed to dodge the knives without problems.
"She's not weak?" Yu Ping turned around to look at the woman wanted to ask her.
In his peripheral vision, a red flamed tip knife flew past with furious speed but in this instant, it went by in slow motion.
