Li Zicheng scolded in his heart, if Lao Tzu knows how to build bridge piers in the water, why do you want to come all the way to Longyou? However, since in the hearts of John Tang and the students, he is a god-like existence, no matter what, he can't let them down.

In the real world, it is impossible to find the answer to such a question, Li Zicheng will travel to the future generations, to see how some famous bridges are built in the world of later generations, Huangpu Bridge, Yangpu Bridge, that is a cable-stayed bridge, does not have reference significance, countless Yangtze River bridges, in addition to Nanjing, Wuhan Yangtze River Bridge, almost are also cable-stayed bridges.

Li Zicheng set his sights on the "Zhuhai-Hong Kong-Macao Bridge" in the south and caused a sensation in the world, because in the open sea, it seems that the "caisson" theory is used, and the "caisson" technique cannot be copied now, but it can be used for reference.

He narrowed his eyes and tried to think about it, and little by little he made his idea a reality: if he used a tin cover instead, cover the place where the bridge piers were poured, remove the river water, clear the silt at the bottom of the water, and put a few more cement piles......

It is now the dry season, the river is only three meters deep, and the iron cover is only four or five meters high, which is not much higher than a one-story building......

Li Zicheng said his idea without reservation, Tang Ruowang and the students were stunned for ten eyeballs, and after a while, Lu Rong said carefully: "Governor, can cement really condense underwater?" ”

"This is going to ask Mingguang and Ji Jie," Li Zicheng himself is also excited, entangled in the bridge pier problem for so many days, and it was solved by himself, the rest of the work should be completed by them, if you can't get full experience, how can you grow into an "expert"? "I asked Mr. Tang to make a thermometer, just to accurately control the temperature in order to produce high-standard cement, and I will hand it over to Mingguang and Ji Jie!"

"Yes, Grand Duke!" I heard that I can also play a key role in this unprecedented project, both of them are excited, young people, where would they think of failure?

"I will leave the matter of pouring the bridge piers and even the construction of the cement bridge to Rongda and Yu Xiao," Li Zicheng looked at the two of them, his eyes were full of encouragement, "As for how to remove the water and how to remove the silt at the bottom of the water, you should study it first, and once the idea is mature, implement it immediately, I want to see how Zhangshui became the first river to be conquered by us!" ”

"Yes, Grand Duke!" With a heavy responsibility on their shoulders, Lu Rongda and Yu Xiao suddenly felt that they were burdened with ten thousand catties on their bodies, but pressure is the driving force, the governor is so trusted, how can he let the governor's heart go down the drain?

They have just graduated, and they can be so trusted by the Metropolitan Governor, if they do this first thing well, they will also be famous in history, the first cement bridge that has never been seen in ancient times......

Besides, the Metropolitan Governor still intends to build bridges over the Yellow River, and this credit will be less than theirs?

Li Zicheng had already seen their thoughts, glanced at them, and said lightly: "How about it, do you have the confidence to complete the task I assigned and make contributions to the Mandate of Heaven Army and the people of Longyou?" ”

"Back to the Grand Duke, yes, we have confidence!" The four of them almost answered in unison, compared with Li Zicheng's understatement, in their hearts, it seemed to be a crater before the eruption, there were countless spirit snakes swimming, and the rolling heat wave was constantly impacting the internal organs, but they couldn't find a breakthrough.

Work, only by devoting yourself to the fascinating work, it is possible to release the impulse in the heart.

Tang Ruowang felt lonely for the first time, his own descendant students, in a blink of an eye, was co-opted by Li Zicheng, he was just a nominal principal, and the students rarely saw each other once a month, he said angrily: "Governor, what about me?" ”

"You?" Li Zicheng thought about it, how could this de facto technical director of the Heavenly Mandate Army stay aside and enjoy Qingfu at such a critical moment? If you really stay out of the matter, I'm afraid it won't be his care, so he said: "They are all young and have not been tested by the wind and waves, and all decisions are ultimately up to you!" ”

"Yes, Grand Duke!" Only then did John Tang become happy.

Li Zicheng also explained some precautions to the two groups of students, all things that cannot be decided, or ask John Tang, or fly the pigeon to pass on the book himself, in short, the Zhangshui Bridge must be built, and try to speed up as much as possible, for the future Yellow River Bridge to accumulate experience.

Gong Mingguang and Ji Jie cooperated with Liu Zhuang to standardize the production of cement and produce high-standard cement as much as possible, while Lu Rongda and Yu Xiao were ready to use pig iron to build a huge iron cover.

Li Zicheng completely handed over the construction of the cement bridge to Tang Ruowang and them, and he rode a horse and galloped to Qingshui County.

At this time, the land distribution of Gongchang Mansion and Lintao Mansion has ended, the people are rushing for autumn planting, Tian Fen is also returning to Qingshui County, only Li Guobu's cavalry is active in the land of Longyou, especially the original Taozhou Wei and Minzhou Wei.

In order to ensure that the new land distribution policy in Longyou can be carried out smoothly and that all other races can "become Han nationality and serve God", they will also be divided into several departments and patrol various places to maintain the deterrence of the people, so as to avoid a rebound in the new policy.

Li Zicheng only stayed overnight in Qingshui County, his mind was not in Tian Fen's belly, and the guard of Guanshan Road was the main focus of his energy now.

The prisoners of war have long been divided into groups and began to pour the two sections of the Great Earthquake Post to Anrong Pass and Anrong Pass to Lao Yeling, according to the plan, before the frost period, as long as the cement is sufficient, the avenue should at least be extended to the Red Deer Station.

After the red deer station, until Qingshui County, it is a straight post road, the road is wide, the roadbed is flat, even if there is no pouring cement, the grain and grass are transported heavily, it will not be too difficult, unless it encounters a long rain, or heavy snow to close the road.

The prisoners of war brought back by Zhou Bin from Minzhou Wei are rushing to repair the road from Laoyeling to Maluyi at this time, and when this section of the roadbed is repaired, it will be transferred to the section from Maluyi to Changning Station and Changning Yi to Qingshui County.

While the prisoners of war were rushing to repair the road, Li Zicheng had already perfected the defense of the Guanshan Road.

Liu Yunshui, Ma Youshui, and Zhou Bin were all concentrated in Guanshan Road, and the auxiliary troops of each department who had stayed in various prefectures and counties had returned one after another, except for the auxiliary troops of Zhou Bin's five hundred households stationed at Anrong Pass to establish the second line of defense on Guanshan Road, and the rest of the soldiers of three thousand households were concentrated in Guguan City.

When Li Zicheng arrived at Guguan, Liu Yunshui's cavalry was still wandering outside the pass, only Ma Youshui and Zhou Bin were in the pass, after the two bowed to Li Zicheng, Zhou Bin said that Ma Youshui complained that he was so idle that his eggs hurt, unlike Liu Yunshui, he can also go out of the mountain every day, and he said: check the terrain.

But when Li Zicheng came to Guguan, maybe he got some information, maybe he had a combat mission, Zhou Bin and Ma Youshui looked forward to it!

Li Zicheng entered the city, inspected along the city wall for a week, and saw that the guards in the city were loose and tight, and nodded secretly, Fang said: "Youshui, Zhou Bin, you two have just participated in the war in Longyou, the casualties of the soldiers have not been replenished, the soldiers have been running for a long time, and they have not rested well, can they hold on?" ”

Zhou Bin said softly: "Governor, although his subordinates participated in the battle of Longyou, the casualties of the soldiers are limited, and there is no need to replenish manpower for the time being—if you need to replenish manpower, there are five hundred auxiliary soldiers!" ”

Ma Youshui followed: "Yes, Dadu Governor, the Eastern Expedition to Longyou, the soldiers who were killed and wounded in the 6,000 households under his subordinates are really nothing, besides, the brothers came to Guguan, and there is no combat mission on weekdays, and they have already rested enough these days, and their subordinates are worried that if there is no combat mission for a long time, the brothers will be tired!" ”

Li Zicheng's heart moved, Ma Youshui was right, if there is no combat mission for a long time, the soldiers will be tired, and the real strong army is grown up with the blood of the enemy in constant battles.

The more soldiers fight, the stronger the army gets!

Mao Taizu's military thinking in later generations is in line with the current Mandate of Heaven Army, and the training ground cannot train a strong army, and if there is a lack of opponents, it will be difficult for the Mandate of Heaven Army itself to develop.

However, in the current situation, the Mandate of Heaven Army can guard the Guanshan Post Road, which is already blessed by God, how can it be possible to attack the east from Guguan?

Even if it can win a steady victory, the Mandate of Heaven Army will not go east of Guanshan for the time being, although it is in charge of Longyou, but after all, it is a newly recovered land, and it takes time to digest, only by completely digesting Longyou, can the strength of the Mandate of Heaven Army be increased.

Compared with the imperial court, the Heavenly Mandate Army is too small, if the imperial court is compared to a dying old man, the Heavenly Mandate Army can only be regarded as a three-year-old child, and self-protection is still insufficient, how can it encroach on the territory of the imperial court again?

If it weren't for the natural danger of the mountain, Li Zicheng would never have gone east to Longyou for the time being. For the sake of today's plan, only to hold on to the Guanshan Road, waiting for the imperial army, if the imperial army ignores Longyou, Li Zicheng will maintain the status quo of Longyou for at least half a year.

But these things related to the overall situation are difficult to discuss with Ma Youshui and Zhou Bin.

Li Zicheng glanced at the low gentle slope to the east of Guguan and said, "Have you ever calculated that in the event of a surprise attack by the imperial court's army, will the rifle be able to block all the paths on the northeast side?" ”

"Back to the Grand Duke, my subordinates have tested it, and these paths are all within a range of four hundred steps," Ma Youshui entered Guguan earlier, and he had already made the surrounding terrain clear, "If it wasn't within the firing range, when the cement avenue was poured, his subordinates were ready to close the road to the north, and all passing merchants and pedestrians must pass through the city, think about it or give up, after all, within the range of the rifle, there is no need to do more!" ”

Li Zicheng nodded, and suddenly said, "Starting tomorrow, Zhou Binbu will take over the guards of the entire Guancheng!" ”

"Yes, Grand Duke!" Zhou Bin was stunned for a moment, and hurriedly gave up his hand.

Ma Youshui was taken aback, thinking that he had made a mistake somewhere, "Dadu Governor ......"

Li Zicheng didn't answer, but said: "Youshui will hand over all the rifles to the auxiliaries, and step up training, no need to train any techniques, as long as you can shoot and have an accurate head!" ”

Only then did Ma Youshui understand, "The Metropolitan Governor wants to train the auxiliaries?" However, in this way, I am afraid that the bullets will be tight, and we have come to Longyou, and there is no ammunition to replenish so far, and the damaged rifle has not been repaired......"

"Don't worry about this, the vehicle transporting bullets and rifle parts will arrive at Guguan in a few days," Li Zicheng said with a smile: "What I care about is, how long does it take for your auxiliaries to drill and train before they can calmly go to the battlefield like soldiers?" ”

"Metropolitan Governor, when I was in Sanchuan Mansion, the auxiliaries had already received basic shooting training, and my subordinates guaranteed that in ten days at most, they would be able to use rifles proficiently!"

"So very good," Li Zicheng was very happy, and said with a smile: "Along with the baggage vehicles, there are enough rifles to equip five hundred households, and there is water, and the auxiliaries of your department will all be issued rifles and collectively turned into soldiers!" ”

"Ah...... Thank you, Governor! Ma Youshui was stunned for a moment, and hurriedly bowed to thank him.

Li Zicheng helped him up, "With water, the number of rifles in your department will increase, and the burden on your shoulders will also increase," he said leisurely: "There is water, Zhou Bin, the army of the imperial court will be eyeing Guguan sooner or later!" ”
