Ye Weiming had obtained this poison needle, laced with "Soul Breaking Ointment", specifically from Xiaoqiao during their time in the Blood Gourd Valley to combat against a man wielding the Heavenly Sword.
Due to several reasons at the time, he had not been able to use it and hadn't found a suitable opportunity since.
After all, for the current Ye Weiming, the attribute of Soul Breaking Ointment to drain 60,000 points of the enemy's health within three minutes is somewhat useless.
Any boss that could be killed by this poison, Ye Weiming could slay it single-handedly without it.
And for bosses Ye Weiming couldn't defeat, even if their health was drained by 60,000 points, he still wouldn't be able to win.
However, he didn't expect that in this special environment today, this seemingly useless poisoned needle would play a huge role in his victory.
There isn't much to say about the subsequent battle.
