简介：Immortal Lord Li Xunxian said: I used my divine power to connect the teleportation channel with the old man Ni Xing, and then threw a chessboard into it. Then we used the spiritual power of the Immortal Essence Stone to freeze the chessboard in the center of the teleportation channel! Finally, one plays chess with white stones and the other with black stones! Now your third grandfather can also play, but he won’t last long!
