Su Zimo was the only one who could remain calm on the spirit vessel.
Su Zimo had fought his way through and was invincible among his peers. He had never tasted defeat and had already accumulated an invincible aura. As such, his mental state was tough and unshakable.
Furthermore, back when he was fighting for the Heaven Slaying Sword Art in Thousand Demon Valley, he had fought against many Overlords and three top Dharma Characteristic Dao Lords.
Dao Lord Extreme Fire was the one that borrowed his body for the short clash at that time.
However, with that experience, Su Zimo would not panic when facing a Dharma Characteristic Dao Lord.
Nangong Ling and the other two had lived for more than 200 years but had never experienced something like this.
In the face of a Dharma Characteristic Dao Lord, they felt despair and were stunned by the words of the old man from Hellfire Hall.
The three of them were panicking and had completely broken down!
