The four gates of Chang'an were crowded with victims who wanted to go out, and Li Jiancheng ordered:

"In the first month of the first year of Yongshuo of the Tang Dynasty, because of the continuous military disasters in Chang'an, the Holy Divine was merciful and ordered the residents of Chang'an, if they have relatives and friends outside, they can directly apply to Chang'an Taishou Mansion for road guidance. Pen ~ fun ~ pavilion www.biquge.info can go out from the four gates of Chang'an! "At the west gate of Chang'an City, a neatly dressed but somewhat shoddy monk stood among the refugees. Wait for the gates to open. When the city gate was opened, the monk glanced at the castle tower and saw two people on the castle tower, one dressed as a boy and the other dressed as a scholar. The monk waved to the man dressed as Gongzi, and then went out of the west gate with the refugees, so that the Gongzi upstairs could no longer be seen.

"Your Majesty, did you say that Master Xuanzang will come back?"

"Yes, definitely." The son is Li Jiancheng, and the scholar is dressed as Di Renjie, the commander of the Qilin secret guard who made Chang'an City famous, Li Jiancheng and Di Renjie came to see Chen Xuanzang off today, in order to hide people's eyes, Li Jiancheng ordered the residents of Chang'an City to leave Chang'an City in the name of joining relatives and friends, in this way, a monk will not be too eye-catching. At this time, a guard came to Li Jiancheng and Di Renjie.

"See Your Majesty! See Master Di! ”

"Hmmm! What's the matter? ”

"Your Majesty, Wei Ting, Du Yan, Wang Gui and other three adults from Lingnan have all returned, and they have arrived in Chang'an, as well as Lord Luo Yi, Lord Fang Xuanling, Lord Du Ruhui who came from Youzhou, Lord Li Ji who came back from Qizhou and Lord Li Jing who came back from Jiangnan, Lord Qu Tutong who came back from Luoyang, and Lord Ling Jingling have all come, and Lord Ling Jing has also brought back a person. Mingyu's father-in-law asked the villain to come and invite His Majesty back to the palace. "Li Jiancheng heard that Wei Ting, Du Yan, and Wang Gui have returned from Lingnan, and Ling Jing has also returned, if Ling Jing comes back, then he must have found Wang Fubao. Li Jiancheng asked the guards what that person looked like?

"Back to Your Majesty, that man's face is full of scars. Big! When he came, the guards were afraid that it was an assassin and did not let him in, and Lord Ling Jing said that that person was personally recruited by His Majesty to Lord Ling Jing, and it was Father-in-law Mingyu who brought Lord Ling Jingling and that person into the palace together after hearing about it. After listening to the guard's words, Li Jiancheng believed that that person must be Wang Fubao, plus Li Jing, Li Ji, Luo Yi, Fang Xuanling, Du Ruhui and others. Now, all the capable generals under Li Jiancheng's command have arrived. Li Jiancheng is going to open his hands and feet now. Li Jiancheng instructed Di Renjie:

"Huaiying, you quickly passed the decree on my behalf, and I decided to hold a ceremony tomorrow at the altar on the outskirts of Chang'an. At that time, all the civil and military high-ranking officials and royal families in Chang'an will have to gather at the altar to watch the ceremony together, of course, except for accompanying the Emperor Taishang in Renshou Palace. The Emperor is old and lonely, so he won't bother the Emperor Qingxiu. Di Renjie obeyed. On the second day, Li Ming, the king of Lujiang, the Shangshu of the Ministry of War, Sun Wuxian, the chief of the Duke of Qi, Sun Shunde, the chief of the Zhongshu of Xue Guogong, Li Gang of Shangshu, Di Zhixun of Shangshu, Xu Jingzong, the secretary and supervisor, Yu Zhining, the imperial historian, Wei Zheng, the Zhongcheng of the imperial history and the counselor, Huang Wenqing, Xu Jingzong, the Qilin Secret Guard, Di Renjie, the Zhongshu Sheren, Song Lingwen, the head of the household department, Pei Kuan, the waiter of the Ministry of Works and the waiter of the Ministry of Rites, Qu Tugai, and other civil servants, Xiong Kuohai, Xu Kuoling, Wang Xiongdan, Xue Rengui, Su Dingfang, Pei Kuan, Qu Tushou, Xue Wanshu, Xue Wanjun, Xue Wanbei, Hou Junji, Xie Shufang, Xue Wanche, Wei Chi Jingde, Cheng Yanjin, Qin Shubao, Niu Jinda, Zhang Gongjin, Zhang Liang, Liu Hongji and other military generals, as well as Wang Gui, Wei Ting, Du Yan and others who returned from Lingnan also watched the ceremony. The agricultural sacrifice ceremony, is in ancient times, the Chinese people in order to sacrifice Shennong's family, teach the Chinese people to plant grains, so that the Chinese people do not have to suffer from hunger, so, in the last solar term of the 24 solar terms every year when the big cold, held the sacrifice to Shennong, and then, starting from Qin Shi Huang, when Qin Shi Huang officially ascended the throne and called the emperor, not only personally sacrificed Shennong, but also joined the emperor personally ploughed the land procedures. With the continuous improvement of later dynasties, the emperor's pro-agricultural ceremony became more and more grand, and Li Jiancheng came to the altar to worship Shennong and opened the sacrificial text he wrote:

"Wei Xi Shennong, Huaxia Kailong, try agriculture, Dehui Li Min, taste herbs, enlightened medicine, pass on the VIII, and ...... generations of Dehong" After reading the sacrificial text he wrote, Li Jiancheng came to the Western Wei Dynasty, which was a piece of farmland reclaimed by the emperor himself, holding a plow, holding a bullwhip in his hand, and carefully ploughing the ground. Half an hour later, Li Jiancheng finished plowing the field with a sweaty head. The ceremonial officials of the Ministry of Rites and the agricultural officials of the altar of sacrifice announced loudly:

"The emperor's pro-agricultural ceremony is over, and I hope that in the coming year, I will have a smooth wind and rain! Harvest of grains! "Nearby to watch the ceremony, Lujiang King Li Ming, the military department Shangshu, the head of Qi Sun Wuxian, Xue Guogong Zhongshu Ling Changsun Shunde, Shangshu Zuocheng Li Gang, Shangshu right Cheng Di Zhixun, secretary supervisor Xu Jingzong, Yu Zhining, Yushi Zhongcheng and counselor Wei Zheng, internal history Ling Huang Wenqing Xu Jingzong, Qilin Secret Guard Di Renjie, Zhongshu Sheren Song Lingwen, household servant Pei Kuan, Ministry of Industry and Ministry of Rites Lang Qu Tugai and other ministers, Xiong Kuohai, Xu Kuoling, Wang Xiongdan, Xue Rengui, Su Dingfang, Pei Kuan, Qu Tushou, Xue Wanshu, Xue Wanshu, Xue Wanjun, Xue Wanbei, Hou Junji, Xie Shufang, Xue Wanche, Wei Chi Jingde, Cheng Yanjin, Qin Shubao, Niu Jinda, Zhang Gongjin, Zhang Liang, Liu Hongji and other military generals, as well as Wang Gui, Wei Ting, Du Yan and others who returned from Lingnan, shouted:

"May the coming year be smooth for me! Harvest of grains! Long live the emperor, long live, long live! Li Jiancheng picked up the towel handed over by Mingyu's father-in-law and wiped his sweat. Li Jiancheng issued an order to hold a banquet in the camp next to the altar of sacrifice, on the one hand, the banquet was invited to the civil and military officials, and on the other hand, it was also for Wei Ting, Du Yan, Wang Gui, Li Ji who came back from Lingnan, Luo Yi, Fang Xuanling, Du Ruhui, Ling Jing, Wang Fubao and others who came back from Hebei. At the banquet, Li Jiancheng issued an order, Feng Wang Gui was appointed as the provincial servant, Wei Ting was the Huangmen servant, and Du Yan was the secretary of the ministry. Wei Ting, Du Yan, and Wang Gui In addition to Wang Gui, Wei Ting and Du Yan can be said to be important supporters of the camp behind Li Shimin, the original king of Qin. They all participated in the conspiracy of Li Shimin, the king of Qin, to seize the heir, and now Wei Ting has become a squire of the Yellow Gate. became a close minister of the emperor's side, and Du Yan was appointed as the secretary of the ministry, in charge of the promotion assessment of court officials, which swept away the depression in Du Yan's heart for many years. Ling Jing was appointed by Li Jiancheng as the squire of the military department:

"Lord Ling, you have always been resourceful, if Dou Jiande had been able to follow your advice, then I am afraid that there would be no such situation as our Li Tang today. I have now appointed you as the squire of the military department, and in the future, I have important matters to discuss with you. Wang Fubao was incorporated into the Chang'an Forbidden Army. After Li Jiancheng returned to the palace, Li Jiancheng recalled the scene when he cultivated the land in the pro-agricultural altar - now most of the ploughs used for ploughing in the Tang Dynasty are handed down from the Han Dynasty, and the plough in the Han Dynasty in China has been basically shaped, but the plough in the Han Dynasty is a long straight plough, and the turning is not flexible enough when ploughing the land, and the soil is laborious and not very efficient. Moreover, the royal cultivated land has been cultivated for almost 100 years from the Northern Zhou Dynasty to Li Tang, and the soil has been relaxed, but Li Jiancheng is still very laborious to cultivate.

"Someone! Bring me a plough for the plough! Mingyu's father-in-law heard Li Jiancheng's shout, and immediately led his eunuchs to bring Li Jiancheng a plough for ploughing. Li Jiancheng carefully observed and fiddled with the plough - the plough is composed of ploughshares, plough walls, plough bottoms, pressure irons, plough heads, plough arrows, plough wheels, plough tips, plough evaluation, and plough construction. Efficiency is affected. In addition, because the plough wheel is straight, it is not conducive to turning, and the oxen who plough the land are stubborn, although some people tamed the ox in the form of wearing the nose of the ox when they were in the previous court, but because it is not conducive to turning, the ox must be lifted and turned by three people when reversing the direction. Li Jiancheng thought about it for a while, decided to bend and shorten the plow, and installed a plow disc that could rotate freely on the plowshare. Make the plow frame smaller and lighter. It is easy to turn around and turn, and the operation is flexible, saving manpower and livestock. After the modification, Li Jiancheng asked Mingyu's father-in-law to find a vacant land in the imperial garden and let Mingyu's father-in-law experiment with it. After Mingyu's father-in-law tried it, he complimented Li Jiancheng:

"Your Majesty, this plow is more convenient than a long straight plow, but I don't know what the name of this plow is? Your Majesty, please give me a name! Li Jiancheng smiled:

"Let's call it Quyuan Plow!"

Shennong, that is, Emperor Yan, the founding monarch of China, one of the ancestors of the Chinese nation, was born on the bank of Jiangshui (in the territory of present-day Baoji City) between 5,500 and 6,000 years ago, and was the sun god in ancient legends. Shennong, also known as Shennong, is an ancient Chinese figure, and the era of written records appeared after the Warring States Period. He is known as the "King of Medicine", "King of Five Grains", "Emperor of Five Grains", "Emperor of Shennong", "Emperor of the Earth" and so on. One of the three ancient emperors of China, the legendary inventor of agriculture and medicine, he tasted a hundred herbs, there is a legend of "Shennong tastes a hundred herbs", teaching people medical treatment and farming, the gods in charge of medicine and agriculture, can bless agricultural harvests, people's health, and are regarded as guardian saints by medical halls and medicine stores. "Imperial Century" cloud: "Shennong's reign of one hundred and twenty years, Fan VIII: Emperor Cheng, Emperor Lin, Emperor Ming, Emperor Zhi, Emperor Lai, Emperor Ai, Emperor Yu. According to the Book of Mountains and Seas, by the time of the eighth generation of Shennong's Emperor Yu, Shennong's clan declined and was finally replaced by the Yellow Emperor. And the record of Shennong's tasting of herbs is also from the eighth generation. Therefore, the editor felt that the Shennong clan was expelled to a wild land because of the seizure of power by the Yellow Emperor tribe, and he was depressed, and there was no food, but only to taste a hundred herbs to satisfy his hunger, and then he died by eating poisonous weeds by mistake.
