There is a saying that "the dragon is cunning and suspicious by nature", and there is also "the dragon is unpredictable, thunder and rain", and the first emperor is called "ancestral dragon", Yingzheng is seriously ill and does not know whether it is true or false, but being seriously ill does not mean that there is a problem with the brain, at most it becomes dull, and it is not Alzheimer's disease.

Qin State has worked hard, after several generations of efforts to complete the long-cherished wish of dominating the world, if the first emperor dies, it will be enough, now the first emperor is still in the Qin State, although it is almost the whole world to attack Qin, but it is not completely irreparable, even if it is difficult to dominate the world again, but relying on the prestige of the first emperor to ensure the continuation of the Qin State is still not too difficult, at most it is to completely give up the territory outside the Hangu Pass, and in the north will desperately maintain the battle line with the grassland Hu people on the front line of the Great Wall.

The so-called line of the Great Wall here is not the Great Wall in Hetao Shuofang, but refers to the Great Wall in Beidi and Shangjun.

The Great Wall of Beidi and Shangjun was built during the reign of King Huiwen of Qin, and during the same period or earlier, the states bordering the northern frontiers of Zhao and Yan chose to build a large and long city wall in order to resist the endless invasion of the Hu people in the grasslands. A section was built in one place, and in the end it was connected, because it was too long and too long, and the name of the Great Wall appeared.

Lu Zhe used to think that the Great Wall was the brick and stone city wall he saw, but after careful recollection, he realized that it was not the case. The Great Wall seen in later generations was actually built during the Ming Dynasty, and the location of the Great Wall in the Qin Dynasty was still in the Ming Dynasty near the hinterland of the Central Plains. The current Great Wall is not a brick and stone structure, and there is no important pass such as Yanmen Pass, the city walls are all rammed earth high, except for a very few locations that choose to be built in poor mountains and dangerous mountains, otherwise they are all built on flat ground.

In fact, the current productivity and manpower are insufficient, if the Great Wall is all masonry and stone structure and selected in the steep mountains, with the national strength of various countries in the Spring and Autumn Period and the Warring States Period, it will not be possible at all......

"I heard that General Meng Tian built a military fort in the Northland and Shangjun Guang?" Lu Zhecai was reluctant to take on the topic of the long-cherished wish of the Qin people to take over unification, and asked about the Great Wall Army.

Fusu also seemed to have never said anything about what Lu Zhe would do if the Qin State died, and heard Lu Zhe talk about Northern Xinjiang. Also happy to introduce.

Meng Tian did build a fortress in northern Xinjiang, but it was a little different from Lu Zhe's imagination that there were military forts everywhere. It is difficult to choose a location on a steep mountain to build a city wall, but it is not difficult to build a fortress that can accommodate dozens of soldiers as a warning. When Meng Tian built the fort, it was divided into large, medium, and small, each of which had its own function.

The large fortress is almost the same as the city, and follows the model of Lü Zhe building a fortress in the south, which is divided into the shape of Bagua with a multi-water chestnut structure. The largest fort can be stationed nearly 10,000 soldiers, covering an area of four or five miles, and set up granaries, armories, and wells for hoarding grain, and individual forts close to the river have even dug moats. This kind of large fort is generally used as a stronghold to block the enemy, and can also be regarded as a supply point for the field army, and there must be one almost every twenty miles.

Medium-sized forts were built according to the specifications of 2,000 to 5,000 soldiers. It is also in the shape of a water chestnut, and there will also be corresponding grain and weapons reserves, but as a satellite city of the "horn trend" of a large fort, the number is almost twice that of a large fort, and it is also a large fort with two medium-sized forts.

The small forts are all built on high places or dangerous arteries as warnings, and there are not many on flat ground, and even if there are, they are stored as post stations and the like.

Lu Zhe thought about it in his mind for a while before he figured out Meng Tian's intentions, and dared to love Meng Tian's view of the fort as a line of defense and supply depots, not as a sharp weapon to advance and encroach on the grassland as Lu Zhe imagined.

"General Meng thinks that the current defensive position is on me. If the Hu people want to go south, they must uproot the forts that block the road or cross the road, so they can greatly deplete the morale of the Hu people. Fusu looked like he was waiting for a comment.

Lu Zhe knew that Fusu hadn't finished speaking, and the towering forts were ...... Well, it's a small city at all! The existence of these cities has indeed made it impossible for the Hu people to roar south. After all, even if the Hu people drove cattle and sheep southward and relied on looting to feed the enemy, and they did not need to ensure the safety of the logistics line, did they dare to rush forward without the premise of large-scale annihilation of the Qin army and without uprooting the cities of the cantonment points?

The Hu people are not good at attacking cities. Even if there will be a fall of small cities, the casualties of the Hu people will inevitably not be few, so the continuous attack will inevitably greatly reduce their morale. It also offsets the advantage that they are all cavalry marching quickly. To be clear, Meng Tian's thinking direction is right.

"Admire!" Lu Zhe was convinced not only by Meng Tian's direction of thinking, but also by the great power and speed of Qin's creation.

"The cost is very high, in order to build those forts within two years, the treasury has almost been emptied, and even the people are ......" Fusu showed a sad expression, finally showing his compassionate side.

Indeed, in order to build those strongholds that are called military forts, but they are actually small cities, the cost will not be small, especially on Meng Tian's side, unlike Lu Zhe, who has a full set of construction techniques, and will also use different construction techniques according to different situations.

"I heard that Lu Hou established a Xiongcheng in Nanjun, which covers an area of two million hectares," the hectare in Fusu's mouth is not the hectare in Lü Zhe's impression, and the current hectare area is twice as small as modern calculations. He said in a curious tone: "There are five walls, each with a minimum of seven zhang and a maximum of nine zhang, and even three of them were built with a new thing and technique that is harder than rock?" ”

Lu Zhe knew that Fusu was talking about a concrete structure, and the construction of Nanling City had been using new technology, but there was no three-way concrete city wall, after all, there was not enough steel to support it, and the life of the concrete building was too short and too short, so it was stupid to use huge manpower and material resources to build this thing.

Obviously, the Qin State also wanted to acquire concrete technology, and also had an unimaginable desire for more and more roads paved with cement under Lu Zhe's rule.

Sure enough, then Fusu really mentioned the matter about the cement road.

"What technology is Daqin willing to exchange for?" Lu Zhe has no objection.

The Qin State's emphasis on roads can be said to be the strongest in all dynasties, and there is no one. After the Qin generation, no dynasty has ever built roads on a large scale, not because they don't know the importance of unobstructed roads to the country, but because they were frightened by the example of the Qin state.

The construction of the straight road requires a large number of manpower, and the manpower required by the cement road is not simpler than that of the Qin Xiu straight road, and to be honest, the life of the cement road is much shorter than that of the Qin straight road. Qin must have seen that Lu Zhe had built so many "national roads" within two years, and he didn't know that he thought that cement roads were easy to repair, so he was eager to get them, and he didn't understand that the speed of road construction under Lu Zhe was related to the division of labor.

"What does Lu Hou want?" When Fusu saw that Lu Zhe was willing to exchange, he was immediately overjoyed.

Lu Zhe hesitated for a moment and hesitated: "A full set of assembly line technology? ”

It's a bit of a bully, the secret of the full set of assembly line technology is that Qin's national strength is lower than that of other countries, but it is better than other countries in terms of production, and Lu Zhe just needs to help Qin build a cement plant and teach the division of labor and excerpts of the modern engineering team.

Then again, the knowledge that Lu Zhe knows is more than 2,000 years ahead of this era, and it doesn't seem to be a bully?

Fusu was refreshing, and immediately decided to change. He knew that Lu Zhe's subordinates were also implementing the assembly line system, but the important processes and details were not as good as the Qin State, and the Qin State would not suffer a loss by exchanging these secrets for the road construction method that was very important to the Qin State.

Next, the two sides finalized a lot of things that could be exchanged, until the combined forces of Qi, Yan, and Zhao finally sorted out the army and began to approach, and when they were about to separate, Fusu mentioned the matter of cavalry being able to charge hand-to-hand combat.

"Prince, it's not that Zhe is stingy, it's not that Zhe is unwilling, but it's not necessarily a good thing for Qin State to get it, and the price is so high that Qin State can't bear it." Lu Zhe had an expression on his face that I was not lying, and added in his heart: "Even I can't afford to pay this price." ”

"Is that so?" Fusu thought about it for a while, and finally nodded and didn't know if he understood, and replied, "Got it." He smiled bitterly and asked Lu Zhe to help him get on the horse.

Lu Zhe felt very helpless, in order to help Su Neng run away before the Qi, Yan, and Zhao coalition forces approached, he had to go over to help. He broke his thoughts while helping back, and he had a kind of resentment that no one could understand.

Fusu, who was finally riding on horseback, asked with a smile: "We're friends, right?" ”

Lu Zhe didn't answer immediately, he walked to his mount and turned over his horse neatly before smiling and saying, "Yes, we became friends." ”

Fusu sighed and whispered, "I hope we won't meet on the battlefield." As he spoke, he showed a simple smile and shouted loudly: "Lu Hou, there will be a period later." He almost fell off his horse in a gesture of giving his hands awkwardly, and after steady, he shouted again, "Next time I see you, I should call the king of Hanzhong!" The voice was accompanied by the distant back.

In fact, Lu Zhe heard Fusu's murmuring, and he looked at Fusu's back with a somewhat complicated expression.

Whether they will meet with the Fusu battlefield does not depend on the two of them, whether the Qin State can stand tall and regain its strength, and whether Lu Zhe can have enough power to sweep the world before the Qin State falls.

After riding his horse back to his own formation, Lu Zhe immediately asked about the movements of the alliance forces of Qi, Yan, and Zhao, and learned that it was close to the range of ten miles, so he ordered the army formation to break away from contact with the Qin army, and then looked at Meng Yi with a sullen face: "Neimou, you can go back." ”

Meng Yi seemed to have known that this would be the case, nodded and asked, "What about ten thousand Qin pawns?" ”

Lu Zhe grinned: "Prince Fusu gave them to Ben Hou as a meeting gift." ”

"......" Meng Yi's expression instantly became stunned.

Of course, it is fake to say that Fusu took the army as a meeting gift, but Lu Zhe has always had a habit of co-opting Qin soldiers...... (To be continued......)
