In mid-November, Huang Chao led the thief army to conquer Ruzhou, and then marched northward without stopping. The Tang Dynasty sent troops from Hedong and Tianping Domains to suppress it. Huang Chao claimed to be the general of Tianbu, and the thief army was like a bamboo, and on the 17th he conquered the eastern capital Luoyang. The eastern capital of the Tang Dynasty stayed behind, Liu Yunzhang led hundreds of officials to welcome the surrender, and the city was Yanran. The rebel army claimed to be 600,000, and Huang Chao was ready to lead the army to attack the west immediately and overthrow the rule of the Tang Dynasty. Tang Ru and Zheng Du commanded Qi Ke to surrender Tongguan with 10,000 people.

A heavy snowfall, the sky and the earth are white. The two girls were playing in the snow, and the laughter was heard far away. In the hall, Li Jie and Zhong Wenwu sat together eating a stewpot, and Liu Qi said, "Your Highness, Huangchao has occupied Luoyang, I don't know what Your Highness has planned?" Li Jie took a bite of food and thought about it, "I can't control Huang Chao at the moment, and I don't want to care about it, it's no problem for me to defeat Huang Chao with my current strength, but what about after that?" The eunuch town of the family, nothing has changed in this world. And what I want to do is to solve these problems completely, so what I need to do now is to build up strength and grow myself. Solve the three towns first and then solve Huainan, so that once the world changes, I will have enough strength to dominate the world. ”

Chen Ziqi arched his hand and said, "Your Highness, what we are lacking at present is grain and grass, although there are currently nearly 800,000 stone of grain, but it can only last until April at most, and after April, we will be completely out of food!" Li Jie thought for a while and said, "Mr. miscalculated, at present, we rely on hunting so that the people can eat meat once a month, and the rabbits raised by each family can be slaughtered next month, so that each family can eat rabbit meat once a month, and after three months, each family can basically eat meat once in seven days, and at that time the chickens and ducks raised by each family can also lay eggs, so that the people's demand for food will be greatly reduced, at least for one more month." And Huangchao will definitely attack Chang'an after a while, so Luoyang can make a fuss, spend a lot of money, I don't believe we can't buy grain, and the three towns can also buy grain at a high price first! ”

Li Jie asked again, "Mr. Liu, how much farmland is there at present?" Liu Ziyu arched his hand and said, "Your Highness, there are currently more than 60,000 acres in the mountain, and nearly 20,000 acres outside the mountain!" Li Jie thought for a while, "Each of these fields is twenty acres, and each mu is taxed at a tax of 100 catties, and half of the barley and yam are required." In this way, the lives of nearly 20,000 people are guaranteed! Before the beginning of spring, people are organized, and the gentle slopes on both sides of the valley are opened into terraces, which are also calculated according to 20 acres of households, and the tax is calculated according to 50 catties per acre. Liu Ziyu said, "Your Highness, what is a terraced field?" Li Jie said: "Later, I will draw drawings to explain to you in detail!" Liu Ziyu arched his hand, "Yes, Your Highness!" ”

Li Jie asked Zhao Fei again, "Sir, how are those children arranged?" Zhao Fei arched his hand and said, "Your Highness, the children are settled, but the children's lives are not well arranged." There are also craftsmen who are willing to teach and have not yet recruited people! "Why is that?" Li Jie asked. Zhao Fei arched his hand and said: "It's still the craftsmen who are afraid that there will be no guarantee in the future!" Li Jie thought for a while, "The children over the age of ten are managed semi-militarized, and their daily life is handled by each of them, and every ten children under the age of ten are assigned a female teacher to take charge of the children's lives, and each person receives one tael of silver per month." Craftsmen can go to do their own work in the morning, come to teach the children in the afternoon, and make a contract with them in the name of the king, first give a deposit of twenty taels, five taels per person per month, and then retire, and then give eighty taels of retirement money every three taels a month! The current calculation method is too troublesome, tomorrow I will prepare a set of algorithms, and the teaching will be taught by me! ”

Chen Ziqi said, "Your Highness, there are still nearly 20,000 people who have not been settled, how to deal with it?" Li Jie thought for a while, "The female teacher recruited from these people first, and then recruited a repair team of 3,000 people, which was mainly managed by Mr. Liu. When the yam comes down, I'll build some more workshops, so that basically everyone will have something to eat! ”

Li Jie said to Qin Fang again: "The army is managed by the general!" In addition, 500 people were selected from the whole army, and the king personally trained and selected! Please! "Qin Fang arched his hand" and did not obey the order! "As for Wei Bo, let's leave it alone for now, and wait for the grain harvest to make plans, and Jin Yiwei will strengthen the intelligence collection on Wei Bo!" Xue Liang arched his hand, "Huh!" ”

Li Jie, who returned to the room, asked Xing'er to find charcoal, picked out a few pieces, sharpened the charcoal with a knife, and then tried it on paper, well! The effect is not bad. Let the manager find a carpenter to make the board and ask for whitewashing.

The next day, in a classroom at Gewu College, Li Jie ordered someone to hang the wooden board, took out Xing'er's carefully bandaged charcoal pen, and first wrote on the board with a capital letter from one to ten, and then wrote a series of numbers accordingly. looked at the people with blank faces. Li Jie said, "Arithmetic is one of the six arts of the gentleman proposed by Confucius in my Huaxia, but our current arithmetic has a big problem, the first is that arithmetic is not systematic, and there is a lack of summary of the laws of operation in mathematics, and the second is that the arithmetic operations are all written in words, which is not only very complicated to calculate, but also easy to make mistakes, in contrast, the use of numbers and operation symbols, not only can greatly simplify the operation process, but also make the operation more simple and clear. Now I'm going to show you how. Mr. Zhao, please ask the question! Zhao Fei thought for a long time and said, "Today there is one duck, which is worth five; One duck mother, worth three; Three duck chicks, worth one, where 100 dollars to buy 100 chickens, ask the chickens and henchmen how much they are? Li Jie thought for a moment and began to calculate with formulas on the board. After a while, Li Jie said, "There are three sets of answers to this question, which are 4 male ducks, 18 female ducks and 78 ducklings; 8 males, 11 females and 81 ducklings; 12 male ducks, 4 female ducks, 84 ducklings, if you don't believe it, you can check it! Everyone bowed their heads for a while, and sure enough, what Li Sheng said was all right.

"Using these numbers and symbols, the math calculus becomes simple and straightforward. This method will greatly save manpower in the calculation of grain and grass, the use of civilian manpower, and road construction in the army. So I'm going to teach you all that over the next few days, and I'll leave it up to you! In three days, Li Jie taught addition, subtraction, multiplication and division, one yuan, one yuan quadratic equation to Zhao Fei and others.

Li Jie rested for two days, and on the morning of the third day, 500 people stood in the square outside the hall. Li Jie stood in front of everyone and shouted, "Do you think you are very good," and the five hundred people puffed up their chests. Li Jie shouted again: "But I think you are all garbage!" Five hundred people were enraged at once. Li Jie smiled: "I'm not convinced, right!" Pointing at one of the soldiers, "You come and take me down!" The soldier rushed out and punched Li Jie, Li Jie did not hesitate to fall over the shoulder, and the soldier flew out and fell heavily to the ground. Li Jie pointed again, "You, you, you." Three soldiers rushed towards Li Jie. A side kick then turned around and another side kick to bring down two soldiers, leaving one dumbfounded. Before he could move, Li Jie punched him in the neck, and the kid fainted at that time. The soldiers in the audience were stupid! It's so fast! Li Jie smiled and said, "I only need a hundred, and I don't want the rest!" Run now! "Five hundred people were taken into a valley. The journey to hell begins!

On the first day of December, the advance of the Huang Chao Army passed through Shaanxi from Luoyang, and the front of the troops pointed directly at Tongguan. The peasant army was extremely powerful, and the Tang Tong guards Qi Kerang and Zhang Chengfan not only had few soldiers, but also had been out of food for several days. The officers and men of the Tang Army couldn't eat enough, and they couldn't talk about defending their homes and defending the country, so their morale was extremely low. In order to boost morale, Zikerang took the lead in the battle, and the Yellow Nest Army was defeated. But soon after, the Huangchao army arrived, and the peasant army shouted loudly and cheered, the sound shook Huashan and the Yellow River, and the ground shook the mountains, which made the Tang army tremble. Zikerang desperately supervised the army to fight to the death, and the Tang army finally did not collapse. From noon to unitary hour, the two sides fought for most of the day, and when they saw that the sky was dark, they ceased fighting and returned to their camps.

Zikerang had just breathed a sigh of relief, but the Tang sergeant suddenly messed up. The Tang soldiers were already very hungry because they had not eaten for many days, and began to shout and make noise in a rage. Out of control, the soldiers set fire to the camp, broke up on their own, and went to earn a living. As the commander of the Tang Army, Zike Rang could only watch and was powerless to stop it.

At that time, there was a valley on the left side of Tongguan, which was forbidden to people on weekdays in order to levy commercial taxes, so people called it "forbidden pit". When the peasant soldiers were about to pass the pass, the Tangtong guard did not send troops to the forbidden pit to defend in a hurry. Zike had his men ramble into the Forbidden Pit, which was densely intertwined with thorns, shrubs, and vines, making it difficult for pedestrians to pass through. However, the Tang army rushed forward and passed overnight.

In the early morning of the second day of December, the Huangchao army began to storm Tongguan, and the battle was very fierce, from Yinshi to Shenshi. The Tang army on Tongguan ran out of bows and arrows, and had no arrows to shoot, so they had to throw stones at the Huangchao army.

Huang Chao saw that the Tang army had no arrows to shoot, so he sent people to capture more than 1,000 civilians and asked these people to dig earth and fill the trenches outside Tong Pass. Soon, the trench was filled, and the Huang Chao army successfully passed through the trench and set fire to the Tang army that night, burning the Tang army gate building to the ground. While preparing for a frontal attack, Huang Chao also sent his subordinates Shang Rang to return to the pass from the valley path of the forbidden pit to prepare for a flanking attack.

In the early morning of the third day of December, Huang Chao and Shang Rang began to attack Tongguan in front and back, and the Tang army was hungry and defeated as soon as the battle began.

After Huangchao conquered Tongguan, he stayed in Chengling Ring and continued to advance eastward. Tongguan is the gateway of Chang'an, the Xiongguan is dangerous, Chang'an is no longer in danger to defend, and the fall is already a matter of time.

On December 3, the Huangchao thief army fell into Huazhou, leaving Qiao Ling to defend it, and the army pointed directly at Chang'an. On the 4th, Tang issued an edict appointing Huang Chao as the envoy of the Tianping Festival. In the early morning of the 5th, Tian Lingzi led 500 soldiers to flee Chang'an with 500 people holding Xizong hostage. Chang'an City was in turmoil, and soldiers and civilians rushed into the treasury to steal gold and silk. In the evening of the same day, the forward of the Huang Chao Army was stored in Chang'an. Tang Jinwu's general, Zhang Zhifang, and dozens of civil and military personnel greeted Huangchao on the throne. Huang Chao rode in gold and shoulders, and the thieves and soldiers were all wearing hair, dressed in splendid clothes, and lined up with knives; A ride is like a stream, the baggage is congested, and there is an endless stream of thousands of miles. Residents of Chang'an gather on the road. Shang Rang said: "The Yellow King raised an army, originally for the people, not like the Li family does not love Ru Cao, but Ru Cao lives in peace without fear." When the rebels saw the poor, they often gave money and goods. Within a few days, however, the soldiers began to plunder the market, and the thieves especially hated the officials, and killed them all.

Huang Chao killed the Li Tang clan in Chang'an. On December 13 of the first year of Guangming, the rebels established power in Chang'an, with the country name Daqi and the year name Jintong. Huangchao is the emperor located in the Hanyuan Palace, and ordered the Tang officials above the third rank to be suspended, and the fourth rank below the same as before; with his wife Cao as the queen; With Shang Rang as the Tai Lieutenant and Zhongshu Ling, Zhao Zhang and the Servant, Tang Generals Cui Yi and Yang Xigu and Tongping Zhangshi, Meng Kai and Gai Hong as the left and right servants and lieutenants of the left and right armies, Fei Chuangu as the privy envoy, and Pi Rixiu as the bachelor of Hanlin. Huang Chao ordered that Tang Baiguan go to Zhao Zhang's mansion to register, reinstate his officials, and find those who are hiding from the people, and kill them. Zhang Zhifang Dona died, hid Tang Gongqing in Fubi, and was found to be killed. On December 21, the rebels killed Tang Prime Minister Dou Lu Peng, Cui Xin and others. Huangchao spread the word, and Tang Fan Town surrendered to the Great Qi regime for three or four out of ten. And the family has a lot of gold, silver, grain and grass, Huang Chao slaughtered the family in the name of harboring suspects, and only ten days to get three million stones of grain and grass, tens of millions of taels of gold and silver, and the family completely disappeared in a sword and sword shadow!
