Zhao Hai had fought the shadow race for too long in the lower realm, and he had done a thorough research on them. He was very clear about their weaknesses. To be honest, they had many weaknesses, but one of them was the most fatal: defense.
Yes, shadow clansmen usually wore armor when they fought, especially those with low strength. They always carried their armor with them when they fought, while some high-level shadow clansmen rarely wore armor, which gave people the impression that shadow clansmen had very strong defenses.
In fact, this idea was very wrong, or completely wrong, because the shadow people's defense was really not strong. Their defense mainly relied on two aspects. One was their armor. The shadow people's armor was not bad, but that was only under normal circumstances. Under a slightly stronger attack, their armor's defense was not enough.
