The Great Mechanic Han had evolved his race once; his genes were optimized, so his looks were naturally good. Even he was sometimes shocked by how handsome he was when he looked in the mirror. However, Charm was more like affinity—it influenced the default Favorability and hidden options when communicating with others. The effect of some abilities also depended on Charm, such as the summoning abilities and beast controlling abilities.
When affinity was insufficient, others might refuse to communicate further.
The player that triggered this mission in the previous life definitely had enough Charm, so they did not meet any obstacles. According to Han Xiao's rich experience, if the missions could not be triggered even after following the process that he remembered, it would most likely be because a certain hidden prerequisite was not achieved. In those cases, Charm not being high enough was a common one.
