The Korean Justice Corps aimed to carry out a secret armed struggle to achieve independence, and its leader was Seo Il.

The Korean Righteous was one of those organizations which was established in March 25, 1919, with Seo-il (徐一) and many Daejonggyo members such as Gyehwa, Chaeo, and Yanghyeon.

The Central Light Corps [ko] is an armed group established by the Daejong Church (大倧敎團) in North Gando in March 1911.

[1][2] Although they aimed for armed struggle, they did not have the resources to acquire weapons, so they focused on strengthening the capabilities of the Korean community.

[1][2] Kim Gyo- heon, who became the second Taosagyo of Daejonggyo in 1916, went into exile in Bukgando the following year and prepared for an armed struggle in earnest and launched a diplomatic independence movement.

Immediately after the 3·13 Yongjeong demonstration, a secret organization called 'Free Industrial Complex' was formed at Guoji Street in Yanji County to raise human resources and military funds for the war against Japan, and a monthly salary per person was established.

A union of Daejong followers and believers of other religions, such as the Confucian Church founded the Korean Righteous Corps around May 1919.

The fact that the New People's Association-affiliated nationalists took charge of the military administration association caused opposition from members of the Confucian Church.

Eventually, after conflict, on the 16th of the same month, Kim Seong-guk and the Confucius members broke away from the Korean Righteous Corps.

It was truly the central organization of the liberation movement in Northeast Manchuria, and also paid special attention to local administration and industrial promotion and worked hard to provide guidance.

He also contributed greatly to education by establishing elementary schools and night classes in the villages of Korean residents under their jurisdiction.

Seo Il established his headquarters in Seodaebo, Wangcheong County, a dense forest area adjacent to the border, and steadily proceeded with preparations for resistance.
