When the two of them returned home, Song Yan heaved a sigh of relief. She wanted to see what was Chen Chu Chu up to with her own eyes but she soon realised that it was going to be impossible. After listening to Madam Yan, she realised that not only was she not sure of the strength of that woman but from what she heard, that woman did not look like she was just involved in some basic black magic.
Sending Fang Yanli or going after her without any clear investigation might end up in a big disaster which was why Song Yan did not send Fang Yanli after Chen Chu Chu instead she sent her after Fu Shu Chang.
Though the chances of her getting something from Fu Shu Chang were really small she was willing to take the risk.
