In the autumn of the twenty-fifth year of the Jokhang Kingdom, Emperor Qianhe was seriously ill, and the fifth prince Xinwang was appointed as the prince and entered the East Palace.

In the first month of the twenty-sixth year of Qianhe, the emperor died of illness, and the whole country mourned. The old lord has passed away, the new monarch ascended the throne, and in March, the crown prince ascended the throne as the emperor and took the country name Yuanwu.

In the first year of Yuanwu, the Liao State that was eyeing the border raised an army to attack, and the army pressed the border, and Emperor Yuanwu advocated a war with the Liao State.

The ministers of the Jokhang Kingdom risked their lives to admonish and oppose the war.

In October of the same year, the Liao army swept to slaughter the three cities of Sanhe, Jiumu and Pu'an.

Emperor Wu of Yuan was furious, named Wang Jiannan as a general, Liu Jin as a military advisor, led 200,000 troops to resist the enemy on the frontier, and began a nine-year frontier war.

History is known as the Battle of the First Yuan.

It was the first time in more than 100 years that the Tiger Fu of the Jokhang Kingdom was aside, and the non-Sima clan was in charge of the handsome seal, and the whole country was in an uproar.

Wang Jiannan used the end of the mountain as a natural barrier, firmly stationed in Musha City, and did not let the Liao army cross the Lei Chi step, guarding the inviolable prestige of the Jokhang State and the dignity of Emperor Yuanwu.

In the tenth year of Yuanwu, the Liao State took the lead in sending peace envoys to the Great Zhao Peace Talks, and Wen Boping, the left minister, signed a peace treaty on behalf of Emperor Yuanwu, and finally returned the border to peace.

In March of the same year, after a ten-year absence, Wang Jiannan received the holy decree of Emperor Yuanwu, and the class returned to the dynasty to reward meritorious deeds.

In May, Wang Jiannan was awarded the title of Marquis of Zhongyong and was hereditarily replaced.

In November, Wang Jiannan was greedy and drunk at the banquet, and the emperor lost his honor in front of the emperor, and Emperor Yuanwu went away in anger.

In December, Wang Jiannan had a dispute with Emperor Yuan Wu in the imperial study, and he pointed his sword directly at Emperor Yuan Wu and was arrested by the guards.

Emperor Yuanwu was furious and ordered the arrest of Wang Jiannan's family, and Wen Boping, the left minister, knelt outside the palace to intercede for Wang Jiannan, but Emperor Yuanwu was unmoved. For two days, he was in the snow until he fainted.

Emperor Wu of Yuan ordered that Wang Jiannan be dismissed from his post as the protector general and that the tiger talisman be withdrawn.

The following month, Emperor Wu of Yuan named Sima An as a general, and the Sima family finally returned to the historical stage of the Jokhang Kingdom after a ten-year absence.

In the first month of the eleventh year of Yuanwu, Wang Jiannan retired to the mountains and forests.

Emperor Yuanwu is quasi.

In March, spring is full of joy, everything recovers, the flowery capital is immersed in a peaceful atmosphere, Wang Jiannan stands outside the north city gate, walking quietly, a generation of famous generals so far away from the land he has guarded all his life.
