Dealing with Ming Mei's family was just a small matter for Wang Chen.
The reason he stopped keeping a low profile and passed the certification for an A-level War Professional ahead of time was mainly to enhance his status, thereby gaining higher access within the Imperial system.
Access, for any Imperial citizen, is extremely important.
Higher access implies broader development channels, higher-level resource allocation, and stronger information access...
Also, it allows Wang Chen to face the Scholar Families and nobility without needing to bow and scrape!
In fact, if he wished, obtaining S-level certification wouldn't be a big deal.
But that would be too high-profile.
Wang Chen plans to achieve the S-level certification upon graduation, so when he enters military service in the Empire, he will have the best starting point and won't be relegated to a minor role.
However, Wang Chen is very aware that his peaceful life of study could end at any moment.
