The purple Qi!

Hongjun was indeed the confidant of the way of heaven. He was very cautious and decisive.

He had realized that Chen Xiaobei was up to something, so he decided to act and kill the danger before it could happen.

As long as he could destroy Chen Xiaobei and old Feng's cultivation, Hongjun would be able to rest easy.

It wouldn't be too late to slowly ask him then.

"Shit! Hanxi! Quickly hide behind daddy!"

Chen Xiaobei could not wait any longer. His first plan had clearly failed, so he had to resort to the second plan.

That was to take out the Saint devouring Dao axe and cast the power of the heaven marrow drop at the risk of the magic treasure shattering.

This was the only way he could ensure his and his daughter's safety.

But!

Chen Xiaobei had not told little Chen Xi about the heavenly marrow drop plan.

So, from little Chen Xi's point of view, getting mad to imitate her was the only way to resolve the danger.
