Fortunately, one section of the canal has already been repaired.

At the end of the Spring and Autumn Period, Wu Wangfucha, who ruled the lower reaches of the Yangtze River at that time, in order to go north to conquer Qi and compete for the hegemony of the Central Plains, mobilized the people to dig the canal from Yangzhou to the northeast, through Sheyang Lake to Huai'an into the Huaihe River, because it passed through Hancheng, so it was named "Hangou", also known as the Li Canal, with a total length of 170 kilometers, the Yangtze River water was introduced into the Huai River, and it was the earliest section of the Grand Canal to be built.

If Wei Yanruo repaired the canal to connect the Yellow River with the Yangtze River, he only needed to build the canal from the Yellow River to the Huai River, and then dredge the silted Li Canal.

The canal between the Yellow River and the Huai River, called the Tongji Canal in the period of the Grand Canal of the Sui Dynasty, was opened in 605 in the first year of the great cause of Emperor Yang of the Sui Dynasty, the western section of the project leads the valley and Luo Ershui into the Yellow River from the western suburbs of Luoyang, and the east section diverts the Yellow River water from the northeast of Xingyang Bishui Town, follows the Bianshui (the original tributary of the Huai River), passes through Shangqiu, Suxian and Si County into the Huai Tongji Canal, also known as the Bianqu, is the trunk road of Caoyun.

Wei Yan basically followed Yang Guang's line and began to plan to build the Tongji Canal, but now the Yuzhou, Xuzhou, and Yangzhou through which the Tongji Canal passes are not yet within his control of the sphere of influence, and for the time being only a small part of the Xiuluo Water, Gushui, Bishui and the Yellow River, and the other is in Jizhou, which Wei Yan controls, the northern section of the canal is being built.

The Northern Canal, is to follow the Sui Yang Emperor four years of the Yongji Canal, the construction of the Luoyang to Beiping canal, this canal project is actually very simple, only need to be together with Yishui, Zhangshui, the Yellow River, the amount of work is much lighter than the Tongji Canal, and most of the scope of this canal is in the Jizhou controlled by Wei Yan, which is convenient for mobilizing people's power, and the people of Jizhou are deeply grateful to Wei Yan's kindness, Wei Yan is not free labor has wages, the people of Jizhou are very hard, I think it will not be able to be repaired in a few years, there is this canal, In the future, it was very convenient for Yecheng to come to Luoyang or to Beiping, which was convenient for Wei Yan to control the north from Luoyang.

Once the Grand Canal is completed, it will not only be conducive to Wei Yan's political and military control over the south and the north, but also conducive to the transportation and exchange of products between the south and the north, and will also bring the Central Plains culture to the north and to the south, and also bring the nomadic culture of the northern grassland and the culture of the southern fish, rice and tea towns to the Central Plains, realizing the diversification, complementarity and co-reproduction of Chinese culture, and the collusion of several major water systems has promoted the integration and exchange between ethnic groups and international exchanges between China and foreign countries.

The land Silk Road will be dredged in a few years, the Maritime Silk Road will be opened in more than ten years, the land Silk Road starts from Luoyang until Rome, the Maritime Silk Road starts from Qiantang (the ancient name of Hangzhou) and leads directly to Rome, and the Grand Canal is from Luoyang to Qiantang, so that the Grand Canal connects the sea and land Silk Road, on the one hand, the culture around the Mediterranean, Central Asia and the culture of a certain country's inland are linked and radiated, on the other hand, The cultural exchanges between the northern minority culture and the Han culture in the Central Plains have promoted the generation, consolidation and growth of the big family of the Chinese nation.

Moreover, the opening of the Grand Canal will give birth to dozens of prosperous cities along the river. First there is a river, then there are towns, the latter is born because of the river, prosperous because of the river, big city, means the relative concentration of population, means the gathering of talents, and because of the need and there is a division of labor, there are transportation, there are handling, there are tax collection, there is management, there are shipbuilding, there are warehousing, there are goods distribution, there are trading, there are hotels, there are restaurants, there are beauty streets, there are singing entertainment, there are schools and other institutions, in short, the more and more gathered, the fame is spread farther and farther, and finally becomes a climate, leaving a permanent memory in history, It is expected that Yangzhou and Hangzhou, famous canal cities, can also rise because of the completion of this canal.

A brilliant blueprint was drawn from Wei Yan's hands, and Wei Yan couldn't help but be full of spirit, and he couldn't live forever.

But he quickly calmed down, and he thought of a guy who was also happy and finally failed to die without a place to be buried, Yang Guang, Emperor Yang of Sui.

What Wei Yan is most vigilant about is that as a traverser, the easiest mistake he can make is to be happy.

The Sui Yang Emperor Yang Guang did several major events in his life, such as the construction of the Grand Canal, the imperial examination system, the defeat of Tuyuhun and the reopening of the Silk Road, and the three conquests of Goryeo, all of which were great things for the benefit of the country and the people, but it is a pity that although Yang Guang has talent, it is a pity that he is too eager for quick success and quick profit, and has not handled the relationship between merit in the present and benefit in the future, but has become a sin in the present and benefit in the future.

Yang Guang in the great cause of the construction of the Grand Canal, not sympathetic to the people, excessive labor, increased the burden of the common people, resulting in the boiling of public resentment, Yang Guang did not know self-examination, but also used the Grand Canal to the south of the Yangtze River to cruise, extravagance and waste, even more aggravated the contradiction, is one of the causes of the end of the Sui Dynasty civil uprising, Wei Yanshen thought a lesson, he set the canal to be completely completed after 20 years, only the Luoyang section within two years, only the north section of the river within five years.

After the Grand Canal was built, Wei Yan only carried out meaningful military and economic activities, and absolutely did not engage in cruises.

Of course, the most fundamental reason why Yang Guang made the Sui Dynasty bury was the rebellion of the family gate valve nobles to him, especially the Li Tang gate valve, in fact, at the historical juncture of the transformation of China from the gate valve aristocracy to the imperial examination bureaucratic politics, and from the gate valve society to the gate valve post-gate society, Yuwentai, Yuwen Yong, Yang Jian, Yang Guang, Li Shimin, and Wu Zetian have all made historic contributions, among them, the farthest in the political reform are Emperor Yang of the Sui Dynasty and Wu Zetian, but the latter two are the most splashed with dirty water in history.

In the second year of the Great Cause, Emperor Yang of Sui began to establish the Jinshi Department, coded the imperial examination system, created a far-reaching imperial examination system for later generations, and opened the Jinshi Department. In the third year of the great cause, Emperor Yang decreed: "Those who have a ministry in civil and military affairs are known for their filial piety, virtuous and generous, virtuous and righteous, clean and clean, strong and upright, indomitable in the constitution, excellent in academics, beautiful in literature, talented and strategic, and strong in hips." Emperor Yang of the fifth year of the Great Cause and edict: "The counties should be able to pass their studies, have excellent talents, strong hips, excellent and equal, be diligent in officials, be able to manage political affairs, be upright, do not avoid strong and strong, and raise people in the four disciplines." "The establishment of the imperial examination system emphasizes the quality of talent and learning rather than the family, which weakens the hereditary privileges of the gate lord clan." Hundreds of officials are not allowed to be counted for promotion, and they must have a virtuous function, and those who are scorching and conspicuous will be promoted. ”

Emperor Yang Guang of the Sui Dynasty's imperial examination system provided an opportunity for a large number of Shu talents with low backgrounds to participate in politics. The imperial examination system closely linked studying, examination and official work, and improved the cultural quality of officials; The power to select talents and appoint officials was concentrated in the hands of the central government from the hands of the local wealthy families, which greatly strengthened the centralization of power, which was conducive to the stability of the political situation, broke through the monopoly of the family and the family, and played a role in restraining the gate valve.

What Wei Yan is now preparing to do is to weaken the family gate valve and replace it with the imperial examination bureaucracy, in fact, to put what Yang Guang and Wu Zetian did in later generations in advance in the late Eastern Han Dynasty, but Wei Yan is not ready to implement it immediately, he gave himself 20 years, the education for all is deeply rooted in the hearts of the people, and after everyone in the Han Dynasty knows how to read, he can only win the imperial examination again.

……

These days, Wei Yan's troops were mainly used in Bingzhou and Shuozhou, and the rear troops were empty, as a result, Liu Biao, who was recuperating, decided to raise a large army and smash Luoyang directly, as long as Luoyang was taken, he could cut Wei Yan's men and horses into two sections, and then he could encircle Wancheng and Yiyang respectively.

Wei Yan learned of Liu Biao's military plan early in the morning from the top-ranking spy he had planted in Liu Biao's army, and he decided to do it.

He ordered Hao Zhao, the newly promoted young general, to defend the four southern passes of Luoyang Eight Passes, so as to take advantage of Liu Biao's northward advance.

Hao Zhao is a native of Taiyuan County.

He was born in 181, 17 years old this year, and had just joined the army not long ago, and was promoted from the army by Wei Yan.

……

Historically, Hao Zhao was also a teenager in the army, made many military exploits, and was gradually promoted to a miscellaneous general.

In May of the first year of Yankang (220), Xiping's koji performance colluded with several nearby counties to create unrest and resist Zou Qi; Zhang Jin of Zhangye County arrested Taishou Dutong, while Huang Hua of Jiuquan County refused to allow Taishou Xinji to take up his post in the county, and they both claimed to be Taishou Ying Koji. The Hu people of the three tribes of Wuwei County also rebelled again. Wuwei was too guarded by Qiuxing, and told Jincheng Taishou and Qiang Captain Fufeng Su Ze was anxious, and Su Ze wanted to lead troops to rescue, and the county officials believed that the rebels were in full swing, and a large number of troops were needed to rescue Wuwei. At that time, the generals Hao Zhao and Wei Ping were originally stationed in Jincheng, but they were ordered not to cross west. Su Ze summoned the main officials in the county, Hao Zhao and others to discuss: "Although the rebels are arrogant now, they have just been put together, and some of them are coerced by the culprits, and they may not be of the same mind as the thieves; We should take advantage of the internal contradictions of the thieves and take advantage of the opportunity to attack, and the good people among them will inevitably break away from the rebels and join us, so that we will increase our strength and weaken the power of the rebels. We have gained the strength to increase the number of troops, and we have multiplied our momentum, and we will be able to defeat the rebels by leading our troops into the attack. If you wait for the arrival of the army, it will take a long time, and the good people in the enemy army will have no home, and they will inevitably be in the same stream as the evil, and the good and evil will be mixed together, and it will be difficult to separate them in the short term. Although there are orders not to cross westward, it is okay to temporarily disobey them for expediency, and it is okay to make your own decisions. Hao Zhao and the others agreed, so they mobilized troops to rescue Wuwei, and the Hu people of the three tribes were subdued. Su Ze, Hao Zhao and others attacked Zhang Jin in Zhangye County together with Biqiuxing. When Koji Yan heard the news, he led 3,000 infantry and cavalry to meet Su Ze, claiming that he had come to help in the battle, but in fact he was preparing to launch a surprise attack. So, Su Ze led his troops and various armies to surround Zhangye, conquered Zhangye City, and killed Zhang Jin. Huang Hua was frightened and asked to surrender. All the counties in Hexi were pacified. After that, Hao Zhao guarded the area west of the river for more than ten years, and the local people and foreigners obeyed him.

At the beginning of the second year of Taihe (228), Zhang He won the battle of Jieting, and after Zhuge Liang withdrew his troops, Cao Zhen (very powerful in the official history, much more powerful than in Romance and "Military Division Alliance") thought that Zhuge Liang would soon attack Chencang, so he sent Hao Zhao and Wang Sheng to guard Chencang and build Chencang City. In December (that is, at the beginning of 229), Zhuge Liang really led a large army from Sanguan and surrounded Chencang, but failed to capture it. Zhuge Liang had already heard that Chen Cang was strong, but when he arrived, he was surprised to see that Chen Cang had already prepared, and to hear that Hao Zhao was in the city.

Zhuge Liang heard of Hao Zhao's prestige in Hexi, considering that it was difficult to capture, he asked Hao Zhao's fellow villager Jin Shen to persuade him to surrender outside the city, and Hao Zhao said to Jin Shen on the city tower: "You are familiar with the laws of Wei, and you understand my person." I am deeply favored by the country and my family is noble, you don't need to say more, only one death. You go back and tell Zhuge Liang to come and attack. Jin Shen told Zhuge Liang what Hao Zhao said, and Zhuge Liang asked Jin Shen to advise Hao Zhao again, saying: "The disparity between the soldiers and the number of soldiers is unstoppable, so why destroy yourself in vain." Hao Zhao said to Jin Shen: "It has been decided before, I know you, but the arrow doesn't know you." Jin Shen had no choice but to return.

Zhuge Liang thought that tens of thousands of soldiers and horses, and Hao Zhao only had more than 1,000 soldiers, and estimated that the rescue troops from the east might not be able to arrive, so he marched to attack Hao Zhao, set up a cloud ladder, the cloud ladder burned, and the people on the ladder were burned to death. Zhuge Liang made a hundred-foot-high tic-tac-toe wooden fence to shoot arrows into the city, and filled the moat with clods of earth, wanting to climb the city wall directly; Hao Zhao built another wall in the city. Zhuge Liang dug a tunnel again, wanting to enter the city through the tunnel, and Hao Zhao dug a horizontal tunnel in the city to intercept it. Zhuge Liang used the car again, but it was discounted. After more than 20 days of attacking and defending day and night, Zhuge Liang was still unable to capture, at this time Cao Zhen sent Fei Yao to lead reinforcements to arrive, and Zhuge Liang had to retreat. This war is the first recorded record of the use of ignition arrows in history, and the record of this war has also become the first time that the Chinese word "rocket" appears in history.

After the war, Emperor Wei Ming issued an edict to praise Hao Zhao for being good at defending the city, and gave him the title of Marquis of Guannei, after returning to Luoyang, Emperor Wei Ming personally met with him, and said to Zhongshu Ling Sun Zi: "There are such bold people in your township, why will this be so, what else can I worry about?" "I'm going to reuse him. However, Hao Zhao soon fell seriously ill, and Emperor Wei Ming was very worried, so he issued an edict to reduce the food of the officials, and Sima Yi wrote a letter to advise.

Before his death, Hao Zhao left a testament to warn his son Hao Kai: "I have dug the tomb several times and used its wood as a weapon for attack, and I know that a thick burial is not beneficial to the dead. You must bury me in your usual clothes. Moreover, when a man is alive, he has a place to go, but what is after death? Now the distance from this tomb, east, west, north and south, is just you. ”

……

After Wei Yan's training, although Hao Zhao was only 17 years old, his ability value had been improved to the level of 92 dominance, 80 martial arts, 76 intelligence, 64 politics, and 72 charm.
