After Zhang Guanghua finished talking for a long time, Lu Xian and the three of them were still staring at Zhang Guanghua's handwriting on the paper with wide eyes, they were in contact with single-entry accounting all year round, although they usually vaguely felt a little inconvenient, but they did not notice that there was anything wrong, today they suddenly came into contact with Zhang Guanghua's double-entry accounting method, and immediately felt the great benefits brought by this method. No matter which link in the bookkeeping is wrong, it can be found out, and the problem of a certain person keeping false accounts can be eliminated.

"Wonderful! It's wonderful! Lu Xian, who was the first to react, immediately applauded, he read a lot and had a wide range of knowledge, and the first thing that came to mind was not that this method solved the current problem of material management, but that he saw the changes that this method brought to the entire business.

Li Lianghong and Wang Chengwen, who heard Lu Xian's voice, also reacted, and the contempt for Zhang Guanghua in their eyes was gone, replaced by deep worship.

The next thing is easy to do, under the guidance of Zhang Guanghua they re-classified and sorted out the general book, and made a model of the correspondence book and the transcription book, Zhang Guanghua also taught them to use self-made charcoal to draw tables, they all praised the use of this pen to draw straight lines is indeed very convenient, but they still choose to use a brush to write. Zhang Guanghua could only follow the customs of the locals, and followed Lu Xian to learn to write calligraphy, but fortunately, they thought that Zhang Guanghua was used to using quill brushes overseas, and they all patiently taught him.

Later, Lu Xian and the others found that Zhang Guanghua would not make mistakes every time he counted, he always wrote and drew on paper and calculated the huge amount of materials clearly. Under their curious questioning, Zhang Guanghua began to teach them Arabic numerals and basic algebra, in fact, in the Yuan Dynasty, Arabic numerals had been popularized among the Mongolian aristocracy, but ordinary people did not have much contact. After discovering that it was possible to check the calculation with formulas, Lu Xian liked this method even more, and this method is especially convenient when calculating big data.

Zhang Guanghua was also very interested in the abacus, the speed of the ancient abacus was comparable to that of modern calculators, and under the guidance of Lu Xian, he also memorized the mantras of multiplication, division, withdrawal and Shang Jiu.

By the time Zhang Guanghua had mastered the brush and abacus, more than a month had passed, and in a blink of an eye, it was the seventh month of the lunar calendar of 1354. When the cave was filled with the last ladder, Zhang Guanghua clearly felt that everyone's emotions were a little excited, and it seemed that the day of the uprising was not far away. Sure enough, as soon as Zhang Guanghua got up that day, Li Da sent someone to ask the four of them to go to the village chief's house to discuss matters together.

Zhang Guanghua and Lu Xian and other four people came to the village chief's house, pushed open the courtyard door, and found that the hall was already full of people, and even there were a lot of people standing in the courtyard.

At this time, Li Da and Lu Guangfu helped the village chief out, and everyone stopped talking, and the courtyard instantly fell silent.

The village chief stroked his beard and said solemnly: "Folks, this day has finally arrived!" ”

"Everyone has been fortunate in the past few months, and the days of fear are finally coming to an end. I decided that the day after tomorrow, on the fourth day of the seventh month, we will officially start the operation. As he spoke, the village chief looked at Li Da and the others beside him again, and began to assign tasks: "Li Da, you take the villagers from the west, starting from the westernmost village in Anxi County, and gather the righteous people from each village all the way from west to east. Lu Guangfu, you led the villagers from the north to the south, and finally we all gathered in Lijia Village, distributed weapons here, and after the formation of the team was determined, we went all the way east to attack Anxi County. ”

After assigning the task of marching, the village chief asked someone to carry out a sand table, on which the location of the county seat was simply marked.

"There are two gates in the county seat, and we meet at the west gate. Lü Guangfu, you led the only few hundred cavalry to feint from the front, Li Da, you led most of the men and horses to ambush behind the Wufeng Mountain in the southwest, this mountain is gentle, and the county seat is the next mountain, and after Lü Guangfu attracts the main force of the defenders, you will act to ensure that the county seat is captured in one go. ”

After arranging the siege of the city, the village chief began to discuss the details of the banner and slogan with everyone, and this time he adopted Zhang Guanghua's suggestion to use the sun and moon flag as the banner, representing that the cause of the uprising can shine with the sun and the moon, and the slogan of the rebel army was "drive out the Hulu and restore China". In order to be recognized by the Red Turban Army in the north, the village chief also decided to let everyone wear a red turban, but in view of the small amount of red cloth that could be found, according to Zhang Guanghua, each person tied a red cloth around their necks, called the "red scarf".

After everyone in the courtyard received the task and went out, the village chief left Zhang Guanghua alone.

"Strategist, I won't go out with the army in this uprising, after all, I'm old and can't stand the bumps on the road. I know that you are resourceful, and on the day of the siege, you will help Li Da a lot, Li Da and Lu Guangfu are both bankers who can only dance with guns and sticks, and they are okay to attack the pool and plunder the land, but when it comes to strategy, you can only rely on you, and success or failure is in one fell swoop! ”

"Don't worry, the village chief, I, Zhang Guanghua, must have worked hard and died."

In the next two days, Zhang Guanghua was obviously busier than before, he had a large number of material exchanges to be registered every day, and in his spare time, he had to coordinate the women in the village to make flags and red scarves.

……

On the fourth day of the seventh month of July 1354, one morning, Zhang Guanghua waited at the entrance of the village with Lu Xian and others, as if they were waiting for the results of the college entrance examination. It was estimated that it was ten o'clock, and finally saw smoke and dust rising in the distance, and everyone was so excited that they celebrated.

On this day, Zhang Guanghua was busy, the village was full of people, Li Da and Lu Guangfu were busy dividing the righteous army into ten, one hundred and one thousand households in the village, although the specific number of people could not be counted, but there were about 10,000 people, he himself served as 10,000 households, and Lu Guangfu was the deputy 10,000 households, but everyone was commensurate with them as generals.

Zhang Guanghua commanded the soldiers to pull out the weapons one by one and distribute them to everyone, even then there were still many people who did not receive weapons, so they used hoes, nail rakes and other things that they usually do farm work as weapons.

When everything was arranged, Zhang Guanghua led the baggage troops to drag the grain, grass and rushing carts and other baggage, and followed the army to the county seat.

……

A sudden shower obscured the smoke and dust of the march, the scorching sun crept out again, and the clouds in the sky were reflected in the raindrops on the flowers and plants, condensing into a Sumeru world. A caterpillar hiding from the rain is industriously nibbling on the jade leaves. "Poof", at this time a yellow bird flew by, grabbed the insect and flapped its wings and flew away. Sure enough, the early worms were eaten by the birds.

As the birds flew by, you could see that before the sun was completely sprinkled, a dense group of rebels had gathered behind Wufeng Mountain, and various flags were fluttering in the wind. Although there are flags of various colors, shapes, and sizes, all of them are sewn on the flags with a round sun and a half-moon of cloth.

"Brother Li, how many people are in our army now?" , Zhang Guanghua withdrew his gaze from the sea of flags all over the mountains, looked at Li Da and said. In fact, as long as the number of troops exceeds 5,000, it seems to be boundless.

"Now there are more than 10,000 people, and some volunteers have joined along the road in the morning, and the number is increasing." Li straddled the scimitar with a big waist, held the handle of the knife, and the armor and helmet on his body shone in the sun, and said with a righteous face.

The army behind the mountain is led by Li Da, and it already has some military appearance, ten households, hundreds of households, and thousands of households, plus his own positions of ten thousand households, have been determined, and everyone is sitting within the scope demarcated for themselves. The task of Li Da's army was to break through the city walls with ladders, open the city gates, and then occupy the yamen, granaries, and armaments. Lü Guangfu had another task, he commanded only a few hundred cavalry, armed with bows and arrows and sabers, and waited by the river in the left rear of the county seat, where there was an official road leading directly to the county seat. His task was to attract the main force of the defenders of the county, assist the main force in the rear attack, and if necessary, act as the vanguard after the city was breached. The signal they agreed to attack was at noon, signaled by the chirping of birds.

At this time, Zhang Guanghua was dressed in monk's robes, wearing rattan armor, with a round head, and holding a ring stick, like Jueming in "Shaolin Temple". The main thing is that he thinks the armor is too heavy and the weapons are too heavy, and the most important thing is that he is afraid of death, and he is not prepared to strike, but fortunately, everyone treats him as a military advisor and does not mind.

In fact, Zhang Guanghua himself knows that the loess city wall of the county is not high, and the guards are only a few hundred households, and there are not many cavalry and musketeers, this battle is very safe, as long as the siegers are dozens of times more than the number of defenders in history, the city is generally unable to hold.

A glimmer of blazing sunlight shone down, and with the faint sound of horses' hooves trampling by the river, the team on this side also began to move closer down the mountain, and it was estimated that they would be able to enter the battle position in five minutes.

When they arrived at the city, they found that the troops in the city had been attracted by Lu Guangfu's cavalry, there were not many guards in the rear, and the guards were busy, so it was estimated that they were redeploying troops. Then it was all about Li Da and Lü Guangfu, who divided the infantry into three parts, the first part of the rattan armor regiment was used for exploratory attacks, the second part of the ironclad regiment was used for the main attack, and the third part was the reserve mobile regiment.

The drums were sounded, and first a group of people with shields rushed out in formation, clearing the deer wood and wooden stakes, and then paved the moat with wooden planks to make a bridge. At this time, the Yuan army finally sent the defenders over, and with the rhythmic drumbeat on the city wall, a dense rain of arrows poured down. A group rushed to the bottom of the city, the Orion archers returned fire on the spot, and the others immediately climbed the city walls on the ladder. Zhang Guanghua, as a military advisor, promised them, whether they were killed in battle or wounded, as long as they broke through the city, they would ensure that their wives and children and their rest of their lives would have no worries about food and clothing, but if they could not capture the county seat, none of these would be realized, and they would be severely punished if they retreated: the rear team would cut the front team, and the guards would cut the rear team.
