February 1st.
Li Fei took a train leaving Datong Prefecture and returned to Xing City.
This time, he did not bring He Jian and the others, allowing them to stay in Datong Prefecture City to continue the investigation.
Li Fei only brought Lv Wenxing and others, as well as Li Tianyu.
In fact, he had wanted to return home with Li Tianyu on his first day back in Datong Prefecture.
But Shi Caiming had not yet completed teaching him the three techniques of the Saber Technique and, on that day, an issue with the Ghost Slayer Gang had arisen.
Therefore, Li Fei ended up staying in Datong Prefecture City for three days before leaving.
Over those three days, Shi Caiming had simply begun teaching him the three techniques of Tao Power that Hao Yi had created.
He had roughly understood the difficulty of these three techniques and realized that mastering them would require a substantial investment of time.
