Is Lv Dongbin the author of China's ancient chess book Invincible Outside the Cave?

The phrase "invincible out of the hole" comes from a poem left by a person who is good at chess. According to the record of Xixi Yu Cong, a chess player in Baoxin County, Cai Zhou said that if a Taoist priest is good at chess, he must forgive others first and then die in Baoxin. A few years later, he was reburied, but his coffin was empty. There is a Taoist poem that says, "Bad Ke Zhen has a wonderful way to communicate with God, and a game has been played for several years. When you are out of the hole, you must forgive others and forgive others. " "Out of the hole to the invincible hand" was 35 points in seven innings, including:
