"Your Majesty, the art of war is cloudy: fighting a war depends on: one is the Tao, the second is the sky, the third is the earth, the fourth is the general, and the fifth is the law. Dao, can allow soldiers and commanders to work with one heart and one mind, live and die together, and not afraid of the danger of their lives, now the Changrong country has no reason to raise troops to invade our territory, it is a loss of way, and our country to protect the homeland and defend the country, up and down with one heart, the same hatred of the enemy, is the way; Day, pay attention to the yin and yang cold and summer system, Changrong last year's long drought led to this year's lack of forage reserves, the domestic people panicked, so there is a new lord Helian Boxing troops to usurp the throne and seize power, now Helian Shan does not talk about the art of war blindly poor soldiers, choose to send troops in midsummer, at this time the grass is green and yellow, the soldiers and horses are not strong, can not attack for a long time, is to lose its time, and our country has a bumper harvest of grains for several years, six livestock are prosperous, grain and grass are sufficient, can do a long-term war; Land, pay attention to the distance, danger and ease, wide and narrow, life and death, now Juyong Pass is easy to defend and difficult to attack, a husband when the pass is not open, so we occupy the advantage of the terrain; Will, pay attention to wisdom, faith, benevolence, bravery, strictness, the thirteen princes have always respected the law, keep promises, love brothers, sympathetic to the people, and forward to solve the problem of the top arithmetic of the Taibai country, can not be said to be not smart, what is missing, only brave, the thirteen prince's grandfather Yun Tianxiao when he was the minister of the minister when he sent an envoy to the Changrong country, the tongue battle group Confucianism, signed the peace treaty of the Changrong country to pay tribute to our dynasty, one person and a million male soldiers, the thirteen princes have the wind of their grandfather, as long as they are tempered more will become a great tool; Law, pay attention to right and wrong, the thirteen princes can use puzzles to solve the problems of the seven princesses of Taibai Kingdom, and abide by the country, which shows that they can distinguish between right and wrong. I, Yunmengguo, occupy the advantages of the road, heaven, earth, generals, and law, and the art of war has clouds: all these five will be unheard, those who know will win, and those who do not know will not win. Therefore, Weichen thought that the thirteenth prince could not only take on this great responsibility, but also be victorious with the assistance of the king of Nanping and General Fei Zhong. Liu Tingwei said in one breath that he was majestic and deafening.

……

"Zizhao has seen Mr." Prince Zhao and Liu Changlin came to the Calculation and Preparatory Bureau to meet Shang Chen. Since the coming-of-age ceremony ended, the merchants returned to the treasury, but after work, the senior actuaries could not go home to live, and could only live in the calculation bureau to prevent the disclosure of secrets.

"Hurry up, please! Why did the thirteen princes make this great gift, but the business is absolutely unacceptable. ”

"Sir deserves it." Wang Zizhao still knelt on the ground and said: "Thank you for the inspiration of Mr. forward, so that Zizhao escaped a catastrophe, Zizhao is grateful and has nothing to repay."

It turned out that after Shang Zhen and Wang Zizhao returned to the dormitory where the thirteenth prince lived that day, because the prince was not an adult and had not yet been released to the palace, there was no separate VIP room, so Shang Zhen had to be temporarily placed in the study. After Shang Lu came to Wang Zizhao's study with Prince Zhao and Liu Changlin, before Wang Zizhao asked the seventh princess about the problem, Shang Lu accidentally saw the puzzle made of the map given to Wang Zizhao by the Holy Lord that Taifu Chen imitated on the bookshelf, so he took it out with great interest and fiddled with it. Wang Zizhao asked, "Does Mr. Shang also like puzzles?" The merchant replied, "It's just a matter of passing the time when you're bored." But I don't know if you have any new puzzles, this map seems to be a long time old, and you must be tired of playing with it, Prince. ”

Wang Zizhao patiently explained: "This is a special puzzle made when I was nine years old in order to let me remember the names of the prefectures and counties under the jurisdiction of Yunmengguo when Mrs. Chen taught me geography.

Shang Chen's heart moved, and he continued: "The villain also loves puzzles, and he specially made a "Situation Map of the Countries under Heaven" in his spare time, I wonder if the prince is interested in playing with it?" After saying that, Shang Chen took out a puzzle piece from the baggage he had brought. When he opened it, Prince Zhao and Liu Changlin were dumbfounded, it turned out that this map was exactly the same as the one of the Seven Princesses, but it was specially made of jade version of Xuan (a kind of rice paper, thicker than ordinary rice paper).

Wang Zizhao took out a piece casually and looked at it, the color was fresh, as if it had just been made. Shang Shi said with some embarrassment: "The villain is busy with mundane affairs, and he hasn't had time to dye it yet, and he can't be as well-intentioned as Mrs. Chen." As the saying goes, "wine is drunk by confidants, poems are sung to people", if the prince does not dislike it, he will give the prince you a meeting gift, and ask the prince to send someone to dye it, the summer is long, and you can also help the prince to pass the leisure time. ”

Prince Zhao and Liu Changlin placed Shang Zhen in the study, and that night they were going to dye the meeting gift given by Shang Zhen with colors, and the two discussed: "Although the color of the puzzle sent by Mrs. Chen is gorgeous, it is irregular, and this puzzle might as well be dyed according to the different coloring rules of the neighboring two countries." So, the two of them stayed up that night, planning many times, and finally starting from the upper left corner, they dyed the puzzle with the least number of colors in turn, and at the same time, the problem of the seventh princess was solved.

But whether it was Wang Zizhao or Liu Changlin, they had no idea about the seven princesses of Taibai Kingdom who had never met, so the two did not report the matter of the four-color puzzle to the Ministry of Rites, and it was not until the eleven princes cheated that Wang Zizhao came forward, so what happened later.

Shang Yan stretched out his hand and wanted to help Prince Zhao and Liu Changlin up, but he didn't expect Wang Zizhao to bow down and say, "Sir, save me!" Zizhao also asked Mr. to help again! ”

Shang Shi hurriedly knelt down in front of Wang Zizhao and said: "As long as the villain Shang Tan can do it, he must do his best, the prince and the prince please get up first."

"Sir," Wang Zizhao got up and helped up at the same time, and said with a fist in his fist: "Sir, this time the Changrong Kingdom has raised troops to invade the territory of my Yunmeng Kingdom for no reason, and Juyong Pass is in danger, and my father ordered me and Liu Changlin to be the commander and the other to supervise the army, and set off with the king of Nanping County to resist the thieves. It's just that this trip is very dangerous, the army has heavy grain and grass, the soldiers are marching and arranged, and there is still a lack of an actuary to accompany him. ”

Shang Zhen had already guessed the intention of the two, and the thirteen princes, under the strong recommendation of Liu Tingwei, the secretary of the Ministry of Rites, defeated the other twelve princes, and were appointed by the current saint as the general of the expedition to the north, which had already spread throughout the court. Many people are waiting to see the joke, considering that no one is willing to be the prison army, Liu Tingwei also recommended his son Liu Changlin, and now the saint is in line with his heart, two grasshoppers on a rope, in case something happens to the thirteenth prince, the prison army will not be able to escape the blame, this matter is caused by Liu Tingwei, and it will be easy for him to solve it.

So, Shang Zhen knelt down and replied: "The villain is shallow in learning, and the arithmetic is not proficient, thanks to the love of the two princes and the prince, the villain will definitely be the liver and brain, in order to repay the kindness of the encounter!"

It is said that Yunmengguo sent Zuo Jinwu to lead General Li Weili to escort 100,000 stone of grain and the envoys of Taibai Kingdom to the direction of Taibai Country on the West Road, and on the other hand, raised 200,000 troops from Prince Zhao and Nanping Junwang to the north to Juyong Pass, and received an urgent report of the flood in the south. Therefore, Wang Chang sent the eldest prince Wang Zizhan and the twelfth prince Wang Ziqian, as well as a group of people from the Ministry of Industry and the Ministry of Households, to Fuping County, Yinghe County and other places in the south that were seriously affected by the disaster. Since the founding of Yunmeng Country, there has been one of the most extraordinary and long and sad summers in history.
