Everyone knows about Lin Yifan entering the miniature world and picking up a peerless treasure, so him performing ancient martial arts might be possible.
Lin Yifan's sword was extremely swift, disciples with lower realms could hardly see how Lin Yifan drew his sword, only the third senior sister and the second senior brother with higher realms could glimpse a little.
Without a doubt, Lin Yifan was using this ridiculously powerful swordsmanship again; a few months ago, it was this skill that he used to duel with Zhu Kang and made a name for himself.
At that time, he and Senior Brother Zhu Kang were three realms apart, everyone thought it would be an overwhelming victory battle, but unexpectedly, in the end, they fought to a draw, causing Senior Brother Zhu Kang of the higher realm to lose face.
Those who had seen that battle were familiar with this illusory swordmanship, and now, seeing it again, they realized Lin Yifan hadn't used his full strength on the stage earlier.
