Allow me to show you how it's done

While Ren was walking toward the place he felt his disciple's aura, Ren double-checked if there was any other strong person nearby. After a quick scan of the surrounding area, he found no one but instead found a weird sort of energy hidden deep within the sect. Ren didn't really care as to whatever that weird energy was as long as it didn't bother him he would not bother it.

... 

Ren finally saw the battle that was happening, it was between his disciple and a person he did not know. In fact, his disciple was surrounded by several dozen Sword Cultivators. 

Fang Mu was facing the strongest among the group and he was already panting and his Qi was fluctuating wildly. Still, Ren saw the smile on Fang Mu's face, seeing that carefree smile despite being surrounded by enemies and only looking at the opponent ahead of him reminded him of himself. 

'Hoh, I guess he did truly learn a thing or two from me.'
