While they were frightened, the red robed youth in their midst moved his hand. A strip of red silk flew out from his waist and wrapped around his hand, while the other end came toward them and struck one of the Foundation Building cultivators in the neck with lightning speed.
"Whiz!"
Without a scream or cry of alarm, the red silk rope infused with spirit energy breath instantly transformed into a killing machine when it brushed the Foundation Building cultivator's neck. Blood was spilt. The red silk sash returned and attacked another person. That Foundation Building cultivator fell down from the air after his throat was slashed and lost his life.
"Hiss!"
