The reason Yusuf Zuck released the Black Bull Demon was because he feared the Shenmu Elder Demon might kill him and Shane Ray at close range. It's important to know that the Shenmu Elder Demon is surely a powerful expert in the Creation Realm, and this person probably enjoys killing. From the dozen or so members of the Ouyang clan who were hanged, this is a clear example.
So Yusuf Zuck had to be vigilant.
And the Black Bull Demon, after all, is also in the Creation Realm. If it truly comes to a fight, it can hold off for a while.
Yusuf Zuck is betting, betting that the Shenmu Elder Demon wouldn't dare make a move against him, wouldn't dare to abandon his offspring and descendants.
And indeed, after Yusuf Zuck and Shane Ray entered the jungle, the Shenmu Elder Demon merely watched coldly, standing at a distance, while the Black Bull Demon retreated backward. As soon as the Shenmu Elder Demon made any move, he would pounce.
The Black Bull is a powerful brute, a battle maniac.
