A person lets their guard down the most the moment that they think they've won.
This was even more the case with Bing Jun and Huo Fei, these proud young masters who had never lost before. As soon as they were certain of their victory, they completely let go of their carefully laid out plans from before.
Both of them thought that Lin Fan's barrier was running out of power and this was their chance to take care of him. So neither of them had the same caution as before and charged right at him to end this battle.
It was just a pity that this was a trap that Lin Fan had set for them.
Bing Jun was the closest to Lin Fan since he attacked Lin Fan head on, but right before his slash could hit Lin Fan, there was a barrier that suddenly appeared in front of him.
This was the barrier that he thought had disappeared, the barrier that he had thought that he had weakened. However, that weakening of the barrier was just a trick that Lin Fan used.
