This is how people are; it's one thing if they have never seen or hoped for anything.
The worst feeling is having hope and then falling into complete despair.
At that time, Fu Dongjun was deeply trapped in such depression.
And to eliminate distractions and focus solely on advancing, he even left his delicate wife and weak child behind, coming to Ten Thousand Beasts Mountain to excavate a secret passage for himself and locked himself inside, just to pursue enlightenment.
This was the final desperate move, either success or martyrdom.
Fu Dongjun understood that there were only two possible outcomes: either successfully advance and break free.
Or be trapped to death in this stone chamber.
To avoid dying in obscurity, he specially left a map for his young son at the time, instructing his wife that if he did not return, to let their son follow the map to find him once he grows up.
In the end, Fu Dongjun indeed failed to advance, but for unknown reasons, his son never came.
