Not only participated in the war of Japanese invasion of Korea in 1592 as a monk and rendered distinguished services, but also went to Japan after the war and brought compatriots home after conversing with Tokugawa Ieyasu. Government ministers and Sadaebu conferred a government post to Yujeong and his ancestors in three generations for his loyalty during the national crisis. And the people tried to vent their spleen by making Yujeong a mighty monk who compelled Japanese performing Taoist magic. However, Yujeong entered the war from a merciful heart to return the favor of the king and the people and stop the misdeed of the atrocious Japanese invaders. And he desired to end the war as soon as possible and go back to the mountains to discipline himself. After the Japanese invasion in 1592, Sadaebu valued Yujeong and his activity during the war from the perspective of fidelity, a traditional idea of Confucianism, and praised Yujeong saying he was a Buddhist on the outside but a Confucian on the inside. While Sadaebu interacted with Yujeong for a long time understood him as a merciful monk with divine power who came out to the world in the national crisis but went back to the mountains and enjoyed the nature afterwards. After suffering the Japanese invasion and two Manchu invasions, Confusion scholars in the regions wanted to rebuild the disrupted order of local society and secure their position as a dominant force. They made Hyangyak from Confucian idea and emphasized loyalty and courtesy by constructing Seowon and Sawoo enshrining respected Confucian figures and faithful retainers sacrificed during the national disaster. In the early 18th century, Sarim in Miryang regared Yujeong, who played an active role during the Japanese invasion of Korea in 1592, as a loyalist from the local and proposed to build a shrine called Pyochoongsa. Nambung, Yujeong’s disciple in the fifth generation, took the construction of Pyochoongsa as an opportunity to receive a lot of Sadaebu’s epitaphs and literary works. These works stated Yujeong’s repayment of kindness and mercy but most of them evaluated Yujeong as a loyal subject, who performed fidelity, along with the commanders of patriotic soldiers: Joheon, Gogyeongmyeong, Kimcheonil, Gwakjaeil.
