"Root" is the secret organization of Konoha, which trains members of the dark part of Konoha, but it does not belong to the dark part. It is an independent group responsible for secretly protecting konoha, but it is more extreme. Just as trees are born from roots, this organization compares itself to the foundation that supports this big tree, so it is named after roots. At present, Gengen's leader is Tuanzang, and he began to compete with three generations of Huo Ying. Different from the first, second and third generations, Tuanzang belongs to hardliners. Dissatisfied with Huo Ying's cowardice in the past, he led Genggen to eliminate all the potential disadvantages of Konoha by force. Although the starting point is radical, the essence is to protect konoha. Roots: Tuan Zang, Sai, Xin, Feng, Du Lian and Si Jing;

Tuan Zang has always advocated using tough means such as war and assassination to solve the problem, and disdained the views of the first generation of Huo Ying, the three generations of Huo Ying influenced by the first generation of Huo Ying and Gang Shou. So despite his loyalty to Konoha, Gang Shou still didn't trust him. In the mission of Tiandi Bridge, he put the tournament into the seventh class to perform a secret mission. He played a dangerous game to make Sai surrender to orochimaru to facilitate his action. In order to achieve his goal, Sai also gave orochimaru all the information about the secret service personnel. Sai's behavior aroused Tianzang's suspicion. But in the end, it was discovered that Tuanzang Hope Tournament was waiting for an opportunity to kill Sasuke, so as to prevent orochimaru from hurting Muye Village again after taking Sasuke's body. After the mission failed, he said, "Emotion brings hatred, and hatred leads to war."
