In order to find the missing companion Qin Yao, Qi Po found the dream of the world's name: Ancarero Volanvi, and brought him back to the charity for preservation.
Unexpectedly, Ancarero was actually Mo Ci, a subordinate of his "adoptive father" Shan Zheye. Ancarero admitted that Qin Yao's disappearance was related to the "Four Guards (pen, ink, paper and inkstone)". In Ancarero's dream, Bi Yi assassinated Qi Po. The reason why they repeatedly blocked the attack was because of the original stone that was parasitic on the body of the "Four Royals" (Qin, Qi, Calligraphy and Painting).
All their actions are just for the ruthless "adoptive father", because his time is running out, and the rough stone is the "adoptive father"'s only hope for survival.
After getting Qin Yao's "earth" stone, they blocked the chess players in their dreams.
