Super-visioned Son-in-law

*Can people in this world live worse than dogs?  The answer was yes..
He was living worse than a watchdog in the Su family!
On the surface, he was the son-in-law of the Su family, but in reality, he was being looked down upon by the Su family. 
His identity was humble and unremarkable. 
This kind of living under someone's roof finally made him unable to persist. 
Fortunately, the heavens opened their eyes.
After the rising and falling he opened his Eye Aperture because of an opportunity. 
From then on, he roamed freely in the city.
