Chen Ping sank the small boat, then thought about how the Brocade Guards he killed on the mountain were mostly shot to death by arrows.
The only one wounded by the Clear Wind Shadowless Sword was the Innate Expert Black Soul, whose body naturally wouldn't leave any traces, having been turned into ash by Fairy Fubo's qin sound.
The reason he treated Situ Lin's wound a bit and then hid the traces was not because Chen Ping was worried that the sword-inflicted wounds would expose his identity.
After all, the Clear Wind Shadowless Sword can't really be considered a Unique Martial Arts technique.
There aren't many who know it, but if one looks hard enough, ten or eight can still be found.
Mainly, he didn't want others to guess the level of his swordsmanship.
