Qi Xiuyuan had already made up his mind to guide the Crown Prince to take over the government, with Fan Zijin assisting the Crown Prince. Therefore, not only was Qi Xiuyuan slowly handing over his authority to his son, but even Rong Xuan began to hand over his authority to Fan Zijin.
Even though Fan Zijin was smart, he had to 'cross the river by feeling the rocks' because there was no precedent to follow in the reform of the official system. In addition, he suddenly had to bear so much responsibility, so he was occupied with politics all day every day. Moreover, he had to supervise Qi Xiuyuan's treatment and ensure he took his medicine. Also, he had to communicate with Little Treasure, plus take care of Little Bear whose parents were not by his side…
As a result, he inevitably neglected his biological son. Therefore, when Little An became a xiucai and suggested going to his Fourth Uncle, becoming a traveling scholar on the way, Fan Zijin agreed without thinking.
