Starting from Teaching People How to Play Cards in the Ninja World

Chen Tianyi, who traveled to another world, felt that he was very lucky. The role-playing system he carried with him was very impressive. Originally, he had to play the role of a flood controller based on his name in his previous life. The first time I saw it, I drew the Kaiba template. But "Why doesn't this world play cards?" Kaiba said that only playing cards is the proof of bonding. Doesn't the ninja world care about this thing the most? Starting from the Grass Ninja Village, people all over the world started playing cards. This novel and its characters are purely fictitious.
