The Possibilities of the Blood Feather Knife

After returning home, Han Sen spent some time thinking about capturing the red cloud. It seemed likely that petrification or freezing abilities would be effective against the red cloud.

But his own petrifying shockwave was no match for the red cloud's speed. Even if Han Sen teleported right next to the beast, the red cloud could still react fast enough to avoid the shockwave. Its ability to accelerate seemed almost endless.

"But the petrifying shockwave is a power obtained from refining a mutant xenogeneic gene. I need to follow its rigid terms of use to cast it. I can't use it with knife silks. If I could, it might be a lot more useful." 

Han Sen was rapidly becoming obsessed with catching that cocky red cloud.

Turtle did not work on it. Han Sen had tried, but the Turtle image just wouldn't stick to the clouds. When the clouds spread, the Turtle spell would just come off. There were no better methods for applying it, either.
