Feng Mu followed Wang Yangming to learn the Eight Methods of Tianyan, and after a few months, he had some insights of his own.

During this period, some outlaws who did not know the height of the sky and the height of the earth among the bandits in Jiangxi tried in vain to attack Wang Yangming, but they were all captured by him and imprisoned in prison.

Xiao Qi'er doesn't have much to do in the palace, her original family background is a solid family, so she also knows how to write and hyphenate, but she doesn't know much. During the period when her brother Mu was studying with Lord Wang, she asked Feng Mu to take her out to play several times, but Feng Mu reluctantly rejected her because she wanted to recite the heart method and rest her internal strength. So she had to learn to read and write with the master book of the house, who treated her as a daughter and taught her some ancient poems.

Just when Jiangxi was calm, a turbulent wave occurred in the capital thousands of miles away.

Yang Tinghe, the first assistant of the cabinet, returned to his hometown, and Emperor Zhu Houzhao was no longer restrained, and the plan that had been brewing in his heart for a long time finally began to be implemented. The little Tatar prince of Mongolia, he has long wanted to compete with one of them, and he actually saw the letter many years ago from the secret agent of Ouchi, and the other party dared to kidnap the prince, and dared to provoke, and he endured it for so long, it was time to break out.

In the early morning of August 1, the twelfth year of Zhengde, the emperor secretly changed into civilian clothes, and Jiang Bin and others took advantage of people's inattention, slipped out of Desheng Gate, and went straight to Changping. The next day, the cabinet was shocked when it found out, and the university scholars Liang Chu, Jiang Mian, and Mao Ji immediately got on their horses and went out of the city to chase them, and chased them all the way to Shahe Town, only to catch up with Zhu Houzhao, and asked him to return to the palace. Zhu Houzhao didn't listen, he had to go out of the Yongguan Pass.

And Zhang Qin, the patrol of Juyong Pass, is also an acquaintance of Feng Mu, as well as Sun Xi, the general of the gate, who did not know the purpose of the emperor's trip, adhered to the principle, closed the city gate, sat under the gate with a sword, and ordered Guanzhong: "Those who have words to switch will be killed!" Zhu Houzhao was furious and sent a decree to arrest Zhang Qin, but at this time, the performance of the officials in Beijing flew like snowflakes, Jiang Bin saw the ministers in a raging manner, and hurriedly stepped forward to persuade: "The officials inside and outside have been obstructed, and the trouble is not good, please let the saint bear it for the time being, and then make a plan in the future." ”

Zhu Houzhao did not give up, and after a few days, he ordered Zhang Qin to patrol Baiyangkou, and replaced his cronies Gu Dayong to replace Zhang Qin to guard the Juyong Pass, and no officials were allowed to go out of the customs.

Zhu Houzhao fulfilled his long-cherished wish and came to Xuanfu, where he sent a decree to the cabinet in order to go on an expedition and strike at Mongolia, and in order to facilitate his actions, he sent a decree to the cabinet, in the name of "Zhu Shou, the Governor of Military Affairs, the Mighty General and the Chief Military Officer", to mobilize money, grain and troops, and prepare for the war.

In September of the twelfth year of Zhengde, the secret agent from Mongolia sent back the news, saying that there was an abnormal situation on the Ming side, Zhang Qin was replaced, and it was the eunuch Gu Dayong who guarded it. The little prince of Tatar has always had a headache with Zhang Qin and Sun Xi, as well as the young pioneer Li Jing, who has already made a name for himself in the army, and since his old enemy has been replaced, he thinks it is a good opportunity.

Under the orders of the little prince, the Mongol cavalry of 50,000 began to assemble around Yulinwei, intending to invade the Ming border on a large scale. After receiving the report, Zhu Houzhao showed a long-awaited expression, and he quickly gathered the most effective army and prepared for a big battle with the little prince of Tatar.

Under the emperor's order, the defenders in the Datong area began to make deployments, with Datong as the defensive core, the chief military officer Wang Xun, the deputy chief soldier Zhang Shui, and the guerrilla general Sun Zhen stationed in Datong. Heavy troops were deployed around Datong, the settlement fort on the periphery of Datong was garrisoned by Xiao Luan, the general of Liaodong, the Tianchengwei in the northeast of Datong was garrisoned by the guerrilla Shi Chun of Xuanfu, the Yanghewei in the northwest of Datong was garrisoned by Tao Jie, the general Yang Yu, and the general Hang Xiong of Yansui were stationed, and the Pingyuwei on the line from the southwest to the Yatou Pass was garrisoned by Zhu Luan, the deputy commander-in-chief, and the Weiyuanwei at the foot of the North Great Wall was garrisoned by the guerrilla Zhou Zheng, which was the forefront of the battle. The military order was like a mountain, and the 60,000 Ming army was quickly arranged, waiting for the arrival of 50,000 Mongolian cavalry.

In October, Zhu Houzhao personally led his army to Shunshengchuan, and unexpectedly, on the 15th, the Mongol cavalry did not directly attack Datong but diverged southward, and the Ming army at the front had already engaged the Mongol army. Considering the weakness of Zhu Luan and Zhou Zheng's troops, Zhu Houzhao immediately stationed around Datong Shi Chun and Xiao Lu led troops to help, and at the same time asked Datong to take Ma Xun and others to lead and follow behind the Mongolian cavalry, contain them to the south, and mobilize troops from all over Xuanfu to the battlefield.

On the 18th, in Xiunu Village, northwest of Yingzhou City, the Ming army Wang Xun and the Mongolian cavalry encountered, and the two sides engaged in a fierce battle, and the Mongols immediately left the battlefield after fighting for a while. On the 19th, the other members of the Ming army joined Wang Xun and blocked the Mongols to the death at Wulizhai in the north of Yingzhou City, and the two sides fought fiercely until dusk, and the Mongol cavalry could not gain an advantage, so they had to retreat temporarily. On the 20th, Wang Xun took the initiative to attack the Mongolian cavalry out of the city, and the two sides met in Jianzi Village near Yingzhou City and started a big battle. The Mongols had a slight advantage in numbers, and the Ming army immediately sent Xiao Lu, Shi Chun, Zhou Zheng and others to help, but the Mongols sent people to intercept the reinforcements, so that the Ming armies on both sides could not meet, and the situation was very critical. After hearing this, Zhu Houzhao, who was in command in the rear, was furious and personally led the Ming army from Yanghe to the battlefield to support. As soon as the local Ming army saw the reinforcements arriving, it was His Majesty the Emperor who personally led the troops to the front, and the morale was great, and they all fought desperately to force the Mongols to retreat. On the 21st, the Mongols took the initiative to attack the Ming army, Zhu Houzhao personally led the army to rush to the battlefield, 60,000 Ming troops had high morale and bravely killed the enemy, Zhu Houzhao personally killed an enemy in front of the battle. The battle between the two sides was fierce and unprecedented, and they tried again and again to storm the opposing position, back and forth, and the battle was fought from morning to night, and the Mongols had to retreat, and the next day, basically all westward. Zhu Houzhao tried to gather a large army to prepare for another pursuit of the Mongols, but unfortunately encountered weather problems, and the black sand storm was not conducive to the battle, so he had to give up.

The victory of Yingzhou was over, and the warring sides suffered countless casualties, but the Ming court was too risky because the emperor went out to patrol privately, which did not conform to the etiquette, and was too risky.

Emperor Zhu Houzhao showed the evil anger in his heart, and did not pursue the matter too much afterwards, in fact, this is a manifestation of his heroic strategy, after the civil fort, the central military power was handed over to the military department Shangshu to be in charge, and the local governor was in charge, the emperor's military power was elevated, and Zhu Houzhao unexpectedly attacked Mongolia, which not only caught the Mongols off guard, but also held the military power in his own hands to a certain extent.

When Zhu Houzhao returned to the palace, he did not investigate and punish Zhang Qin and Sun Xi, who had offended him and did not obey orders, and he knew in his heart that these two people were loyal generals guarding the gates. On the one hand, he was attacking Mongolia, and on the other hand, he was out of the palace to play, and under the surface of absurdity, no one knew what he really thought.

Zhu Houzhao was slightly surprised when he learned that Feng Mu was no longer outside the city from the secret agent, and asked the secret agent Feng Mu where he was, and learned that he was studying with Wang Yangming, Zhu Houzhao finally showed a relieved and proud smile.
