There was no need for him to take action against the others; the father of the girl with the Mysterious Yin Physique was already instructing his subordinates to do the work. This was a statement of solidarity with Zhou Heng, as they were all in the same boat, advancing and retreating together.
Otherwise, if Zhou Heng wanted to keep the secret and thought about silencing them, what would they do? Now that they were all in the same boat, he naturally wouldn't leak the secret.
Actually, he was being overly cautious. Zhou Heng never cared about whether others knew about his actions—if he were afraid, he would simply not act at all.
After expressing his gratitude to Zhou Heng and gifting him a great number of Immortal Stones, the girl's father finally led his people away. So many had died here; no one wanted to stay any longer.
