It's not just about opening doors; crossing tribulations is similar. On the path of Tao, blocked by obstacles and tribulations, it ultimately boils down to two methods.
Either you behave honestly, follow others' rules, and find the key to open the door.
Or you take up a knife, chop your way through the South Heavenly Gate, and carve out your own path to walk.
So Chen Xuantian brought out the axe.
In this scenario, it is actually the key.
Ahem, well, it still needs to be explained a bit more.
As per his earlier conjectures, this axe is indeed non-material. Although it looks like an axe, once thrown into the water, it infinitely proliferates, splitting into three axes. So when he initially entered the forest with the axe, he actually used the principle of chopping open the door, relying on non-material rules to interfere, breaking through the domain set by Xuan Du.
And in the current scenario, the non-material is the key.
