"Senior Brother Lian, after all, he is a disciple of our Tianxuan Sect. Killing him like this, won't Master Hui Ning cause us trouble if she finds out?" A nearby disciple of the sect asked worriedly.
The man surnamed Lian flashed a sharp look in his eyes and said, "He's merely a nominal disciple who brought skills with him when he came up the mountain. He hasn't even learned the sect's Cultivation Techniques, and besides, this is a normal spar among fellow disciples; we just mishandled it. Death and injury occasionally happen during sparring, even if the Sect Master came, he wouldn't overly blame us."
The nearby sect disciple nodded and said, "Then leave it to Senior Brother Lian, we will supervise and vouch for you."
Since it's supposed to be a "normal spar," it requires a one-on-one duel; if a group attacks one person, it would be detectable from the body's spiritual energy clashes, and the matter could no longer be concealed.
