There are of course countless difficulties in the subsequent implementation stages of the construction of canals between Bowang and Ye County. Whether it is technical demonstration or engineering practice, troubles are indispensable.

But Li Su couldn't write these things in the memorial, because when asking the emperor for resources and determination, he should cut the mess quickly.

It is normal to start working first, then increase the money according to the actual project volume requirements. It is normal to build a project with a budget of 500 million yuan and then add a budget of 20 to 30 billion yuan.

In fact, even before Liu Bei approved this memorial, Li Su used his power to governor Jingzhou to let Gao Shun do this work for a few months-

Didn’t Liu Bei’s camp expand its army this year by 80,000, which were recruits from Nanyang and Ba County, and 40,000 were surrendered soldiers from Yuan Shao and Sun Ce. Because Gao Shun was good at training troops, the training of the 80,000 new troops was placed in the Nanyang area and ate the military rations from Jingzhou.

It is impossible for tens of thousands of people to practice fighting skills and horse riding and archery professional skills every day. They also need to train hard work, obey orders and conduct military disciplines.

Therefore, apart from the reinforcements drawn from Gao Shun when Li Su attacked Zhou Yu, the remaining new troops left in Nanyang were asked to start construction first. Especially during the subsequent winter slack season, the Nanyang garrison could participate in the idle time.

However, he did not obtain the emperor's authorization at the beginning. During the two months of preparation for construction, Li Su did not officially launch the banner of "building the canal", but only said that he wanted to "improve the logistics transportation conditions from Wancheng to Ye County and Kunyang, and rectify the road."

Then, in fact, we must first survey the location suitable for excavation of rivers. Those who should be leveled and dig a little further and build a dirt road.

Anyway, the amount of soil excavated will not be wasted. When further digging into a canal in the future, it is better to continue digging deeper along the already-digged roadbed.

You can also touch the geological conditions at the lowest location of Fangcheng Pass between Funiu Mountain and Tongbai Mountain to facilitate subsequent preparations for digging wells and tunnels in sections to bury black gunpowder and explode the mountain.

All kinds of preparations are all in one go.

Of course, Li Su's style of conduct, which is to act first and then report, conceal difficulties, and then talk about it, should not be used indiscriminately.

It has a major premise: the host must be a clean official like Li Su, who knows the truth. If it is another official, then there must be a strict supervision system, and "preparation of budgets/feasibility demonstrations/environmental assessments" must be missing.

Li Su is so lenient than self-discipline and treats others strictly.

Who made him a saint? He had so much money that his family would never spend it (he didn't want many children and grandchildren). He could open a map editor for the extra money, and he would not be degenerate even if he gave him power.

...

After Liu Bei approved Li Su's entire plan, he ordered the Hebei front to follow the plan of advancing that Li Su and Zhuge Liang coincided with each other, "feint attacking Huguan and Yecheng, but in fact, it attracted Yuan's firepower and then took all the Henan Yin."

On the other hand, Liu Bei spent a few days sorting out all the orders he wanted to give Li Su, and sent a messenger to Wuchang to ask Li Su to prepare for the work and then take time back to Chang'an.

Calculate the days, the previous victory of Guan Yu's troops on the Hebei front was achieved in early September. Later, they paused for ten or eight days to rectify the rear and slowly established rule in the newly occupied areas. Now it is early October, and new military operations can be invested soon.

The work of feinting attacks on Huguan and Yecheng will definitely be taken back before October and a half months. The complete recovery of Henan Yin area is almost the same as the last few days, so it can be done in late October.

The messenger who Liu Bei replied to Li Su could be sent out around the fifth day of the October 20th day, and could be sent to Wuchang on the tenth day of the October 20th. Li Su took some time to hand over the work on the Southeast Line and explained the affairs in Yangzhou. He would definitely be able to leave for Chang'an before late October.

However, Li Su could not run like those specialized expedited messengers. He had to take a car and boat and take his family with him. It was the limit to traveling more than 100 miles a day by land, and he could only reach one-third of the marching speed of a professional messenger.

It’s faster to take a boat on the water, anyway, it’s just that the boatman is tired, so Li Su can sleep and sail on a boat at night.

It takes more than 1,600 miles from Chang'an to Wuchang (the straight line distance is only 1,200 miles, but you can't go straight). The waterway accounts for two-thirds. Li Su will take about ten to twelve days to return to Chang'an. It should be early November by then.

Liu Bei must have many major issues to discuss with Li Su, and it is impossible for him to let him go after just three or five days of meeting him. So it is inevitable that he will leave him for more than half a month to explain all kinds of things.

So by then, the surrounding areas of Luoyang will definitely be completely restored, and the fleeing enemies will be almost cleared and the public security loopholes after the war will be cleared, just in time for Li Su, the Sili Captain.

We strive to take office before early December, and take the supervisory authority of the Sili School Captain to spend two or three months cleaning up and rectifying it. After the Chinese New Year is over, we will be moved to the position of Governor General of Sili.

The rhythm is perfect.

...

It is precisely because Liu Bei and Zhuge Liang's plan was perfect, so there was nothing to elaborate on the subsequent operation stages - because during the execution, there was no accident that caught them off guard.

On the fourth day of October, Liu Bei's order was urgently passed to the Shangdang front line. Guan Yu's troops were still in combat readiness, so they only took a little preparation for two days before turning into an offensive posture.

Even without Liu Bei's order and Zhuge Liang's adjustment, it would be inevitable that Guan Yu would take Luoyang. The difference was that he would go to Huguan to perform now so that he would be more angry in the future and try his best to promote Yuan Shao to die of anger as soon as possible.

On the sixth day of the October 10th, Zhang Fei's troops, who had been responsible for occupying Shangdang County, stationed tens of thousands of troops in Huguan County, and set up a formation at the Huguan entrance to build siege equipment. After a brief siege of two or three days, they could break through the pass.

The place name Huguan is divided into Huguan County, Huguankou, and Huguanxing. The former is a county that has been occupied by Liu Bei's army during Zhang Fei's occupation of Shangdang.

Huguankou is the west exit of the mountain road east of Huguan County, Huguanxing. It has been built since ancient times and is still under the occupation of Yuan Shao's army.

Moreover, even if you break through the Huguankou, there is still more than 80 miles of Taihang Mountain valley road to the east, Yuan Shao's army can set up camps and defend them along this pass. After walking the last 80 miles of Taihang Valley, you can enter the Hebei Plain around Anyang, Handan, and further east, you can completely flatten the river to the Yellow Sea.

Zhang Fei's actions made Yuan Shaojun very nervous, and the land of Zhaojun in Wei County was shocked overnight.

Although the first two days were just assembled a catapult and used a divine arm crossbow to suppress the city wall, it did not kill the Yuan army on the Huguan wall, and the military situation that was urgently requested help was sent to Yecheng again and again.

In Huguan, the walls are not very high and cannot last long after being hit by a catapult. This kind of level in dangerous mountains mainly relies on the narrow and narrow terrain to maintain the advantage of the defense. Even if the first wall is broken, the mountain roads behind will be blocked everywhere for more than 80 miles, so the wall itself is not important.

Zhang Fei's feint attack was very serious. As soon as it entered mid-October, the Huguan Guan Wall had been damaged by Zhang Fei's trench. Before October 15th, Yuan Shaojun finally couldn't hold on and gave up the wall and retreated to the subsequent deep valley camp.

The generals of Yuan Shao's army had realized that the western end of Huguan Pass was not easy to defend because the attack front left by Zhang Fei that place was too wide, and Zhang Fei's large army could remotely output the wall in a fan.

If you retreat to the middle section of the valley, because the front of the valley is so narrow, it will not be so large that it will be able to launch a long-range force for Zhang Fei.

To put it bluntly, in the pre-Qin period, the location of the Huguan level was set at the entrance of the West Terminal Valley. That was because the long-range trencher did not have that threat to the wall of the gate at that time, and there was no need to consider the question of "the area of ​​the battlefield outside the gate was too vast, and would it give the enemy too much room to deploy long-range weapons?"

After learning from the lesson, Yuan Shaojun retreated step by step and delayed defense. However, because he gave up the solid earth and stone walls, the subsequent fortifications were non-permanent. Although he could continue to defend the decisive force, the reserve force needed suddenly increased.

If no reserve team of more than 100,000 people was placed behind the Huguan battlefield, no one would be sure to defend the 80-mile-deep Huguan Pass.

...

On the tenth day of October, the first wave of bad news in the direction of Huguan reached Yuan Shao, who had just returned to Yecheng to recuperate—

Yuan Shao has been retreating for almost twenty days, but Li Yang, who had just retreated to the north bank of the Yellow River, fell ill due to shameful face and was worried. He was ill in Li Yang for more than half a month. Now he is a little better, and he has left for Yecheng again.

After returning to Yecheng for two or three days, Zhang Fei broke the Huguan wall, causing Yuan Jun to resist step by step. Yuan Shao was so depressed, but he could only summon Tian Feng, Guo Tu, Shen Pei and others to discuss countermeasures.

Xu You has fallen out of favor, but because Ju Su, who is opposite to Xu You, is currently in a state of "dead", Xu You has not been liquidated. He still has a superficial courtesy and his official position is still the same, but he does not follow his plan.

Yuan Shao doesn't like to punish the two factions of counselors with opposite opinions at the same time. He subconsciously always feels that "if the person with negative opinions is wrong in one thing, it means that the person with positive opinions should be right. Even if it is necessary to deal with it, he should find other mistakes to deal with it next time."

It seems that this is the only way for him to appear to be more "polite and polite" on the surface and to be well-employed. Yuan Shao always cared about these details to beautify him.

Of course, there was no good solution to the result of Yuan Shao's convening of the counselors. It was nothing more than to draw garrisons from the south and set up defense areas from Huguanxing to Yecheng.

Although Xu You was not very trusted, he still suggested that Yuan Shao formally put the defense of Yingchuan County and Runan County to entrust the full power to Cao Cao and Xiahou Yuan, who is now stationed in Runan.

Yuan Shao didn't want to listen to Xu You at first, but as the second strategist of Yuan Shao's camp, Xu You also developed his own power group, so naturally other strategists would learn from his ideas to deduce and advise.

Who made Xu You's greed and selfish interests far more than Ju Su's? He was much more serious than Ju Su's formation of gangs.

Yuan Shao was seriously ill and stupid, exhausted and underdepressed. In the end, he agreed to this matter, giving Cao Cao more room for operation. At the same time, he tried his best to pull the troops south of the Yellow River back as much as possible, shortening the front line to withstand the upcoming "War of Huguan-Yecheng" that he felt was coming.

Fortunately, Guo Tu, who is good at flattering, has tried to tell Yuan Shao various good news about mysticism these days, which has helped Yuan Shao recover a little, and it seems that he is still in a tendency to heal.

Guo Tu's words are nothing more than "After Bai Qi won the Battle of Changping in history, because of his arrogant arrogance, the Qin army continued to attack Handan, but wasn't it still a crushing defeat?

Moreover, how similar is history? After the Battle of Changping, Bai Qi was replaced, and the brave but unscheming Wang Ling was immediately fighting the Battle of Handan.

Now that Liu Bei defeated our army in Hanoi, he did not suspect Guan Yu, but he actually despised our army and did not let Guan Yu's entire army attack our Yecheng. Instead, he asked Zhang Fei, a brave and unscheming general, to lead a side army that had previously captured Shangdang, to directly underestimate the enemy and attack our Yecheng. Zhang Fei's miserable defeat will inevitably be worse than that of the Qin general Wang Ling! The lord will definitely be in a bad state!"
