Cui Xinyun could have taken action to kill these people from Immortal Island, but it wasn't necessary.
If she killed this group, Immortal Island would certainly send even more powerful individuals, which would be quite a headache for Cui Xinyun.
Therefore, Cui Xinyun decided to stall... essentially to buy some time.
For now, the Heaven-Filling Stone is in her hands, so Immortal Island won't trouble Mo Lin over it.
The Heaven-Filling Stone is very important to Immortal Island and can even lift the special restrictions on the island.
If Immortal Island obtained the Heaven-Filling Stone, it would cause a lot of trouble.
The best approach right now is for Cui Xinyun to hide with the Heaven-Filling Stone.
Cui Xinyun had already planned a counter-strategy, using her identity as a Twenty-four Solar Terms Envoy to negotiate with Immortal Island.
In any case, she was prepared for the worst.
At the worst, she'd just escape with the Heaven-Filling Stone.
