Jian Wushuang did have two kinds of venom in his hand.

One was the 12 drops he had gotten from Nine Whiskers. Although he had used one drop and sold another nine drops, he had already refined the remaining two drops and fused them into the Wuqi Divine Sword.

This was the poison he had used to deal with the Blood Thunder General. Although this poison was personally refined by a poison Ruler of an Ultimate Ruler, it was extremely powerful and could easily kill a fifth-level Ruler, however, if it was used to deal with an Ultimate Ruler, some of the weaker Ultimate Rulers might fall. However, as long as they were slightly stronger, they could still forcefully block it.

The Blood Thunder General survived the attack of the venom.

However, this was also because Jian Wushuang did not kill him directly. If he wanted to kill him, he would use the second venom, which was the pitch-black venom in his hand.
