The dead give way to the living

Han Song has been in great grief ever since his son was killed.
He contacted the Jiang family and then the Valois family, determined to use the power of the three families to avenge his son!
But several days passed and Mr. Long still hadn't said anything. Jiang Qingying also kept making excuses, saying that he would naturally deal with the Dietrich family's affairs after Mr. Long was done with his work these few days.
Helplessly, Han Song could only bury his son first, and then use Rocco...
