After they married, they were penniless.
Although Liu Zijun had no great demands for Xue Zhuyong and they led a life of happy poverty, Xue Zhuyong suddenly realized the responsibilities he should bear after getting married, as well as the importance of social status. To prevent his beloved from suffering, he had to attain a certain status.
In the Mo Family, the best way to improve one's status was through swordsmithing.
Despite his aversion to the Mo Family, Xue Zhuyong decided to learn the art of sword casting.
The gentle Liu Zijun naturally supported her husband's decision, without hesitation taking out all their savings to barely afford a small courtyard with a sword casting chamber, which they named South Garden.
Xue Zhuyong focused on sword casting, while Liu Zijun took care of his diet and daily life, managing their little household.
However, unbeknownst to him until he started to seriously study it, Xue Zhuyong discovered he had an astonishing talent for sword casting.
