readx;???? After making contact with the personnel sent by Han Xin, Chung decided that Han Xin's troops were exactly what he wanted to do, but could not do due to the limitations of his own support. Pen % fun % Pavilion www.biquge.info

That is to divide the troops to cut off the connection between the attacking troops under Tian Heng's command and the large camp of the Qi army, and try to keep these troops under Tian Heng's command inside and outside the first barrier as much as possible.

After Han Xin knew Du Cong's thoughts, he couldn't help but have some doubts in his heart, that is, he didn't expect that Du Cong would actually be captured by Tian Heng in the first line of defense system.

For such a situation, to be honest, Du Chung himself didn't understand why this happened, but for Du Cong, it was no longer a matter of worrying about why his defensive line seemed to be vulnerable, but how to take advantage of the opportunity when Han Xin led the army to reinforcements and leave these Qi officers and soldiers who dared to launch a night attack behind.

After thinking about it, Han Xin didn't think of what caused this situation. Because judging from the battle report fed back to Zhang Jiashi from the front, although there are still some imperfections in the defense system arranged by Du Cong in this regard, from the perspective of the entire defense system, it cannot jump out of serious flaws.

After figuring this out, Han Xin quickly ordered the Lou Chuanshi troops to drop them into an area about three kilometers north of the west of the current combat area.

There are also some shoals in this area and a small number of abandoned Qi army camps, and the defense system of these areas is more to avoid the Qin army from a large-scale surprise attack on the Qi army's camp from another direction.

But in the intervening months, the small camp did not play its role in the area.

It's not that this area was captured by the Qin army, but during this period of time, the Qin officers and soldiers did not carry out large-scale shipping again. And just for the transportation of materials, the port area built by Chung Toh behind the second line of defense system is enough to complete this kind of task.

Therefore, more than a month ago, Tian Heng finally withdrew this part of the garrison of the camp that had in fact escaped more than half of the troops.

Perhaps, Tian Heng should know an allusion, that is, smuggling Yinping.

The smuggling of Yinping was a decisive military operation in the battle of Wei to destroy Shu in August 263 AD, and the Wei army on the eastern route under the command of Zhong Hui was the main force, which was blocked by the Shu army in the dangerous place of Sword Pavilion and could not advance. After capturing Yuzhong, Deng Ai, the commander of the Wei army's western route, suggested to Zhong Hui: "If you sneak through Yinping and go straight to Fucheng, the defenders of the Sword Pavilion will definitely come back to rescue Fucheng, and the army will be able to advance by taking advantage of the momentum; if the defenders of the Sword Pavilion do not retreat, Fucheng will be empty and will definitely be captured." Zhong Hui accepted this suggestion and ordered Deng Ai to implement it. Yinping and the Sword Pavilion are separated by more than 100 miles, it is the residential area of the Qiang nationality, the mountains are steep, it is difficult to walk, and the Shu army has no fortification. Deng Ai set off from the middle of the city, passed through the Yinping Trail, and went straight to Fucheng. Ma Miao, the defender of Fucheng, faced the Wei army that fell from the sky and surrendered without a fight. From then on, the Wei army quickly connected Fucheng and Mianzhu, approaching Chengdu, Liu Chan surrendered, and Shu Han died.

Of course, the point of this allusion is that Zhuge Liang once realized the importance of the Yinping Trail, and once arranged about 1,000 troops in this area to build a camp here for defense.

However, after Chen Yi's death, the power of Shu Han was gradually hindered by Huang Hao, and this camp was also removed.

This has become the most important key to Deng Ai's success in smuggling Yinping.

If this camp of only about 1,000 people is still there, the Shu Han army that condescendingly resists the offensive of Deng Ai's army can even be said to be able to easily turn Deng Ai's army into a ghost of Yin Pingdao.

And this Qi army camp, which originally had a scale of less than 500 people, seems to have played an important role similar to that of the Yinping camp.

Because Han Xin, after letting the troops carry out a large-scale landing, once said a sentence in front of this camp:

"If there are still Qi people here, then it is probably impossible for us to achieve a complete victory in this battle. It's a pity that the Qi people will pay the real price for their actions. ”

When Han Xin said this, there was also a part of luck, that is, Zhang Jiashi's words were still good.

That's luck, which really makes many people can't see and touch, but it affects the trend of many things.

......

Han Xin's army is mainly a mixed force.

Its 30,000-strong Lantian army has 4,000 knights, 400 crossbow chariots, 6,000 heavy infantry and more than 18,000 light infantry troops.

These forces also had to abandon another 600 crossbow chariots and more than half of the baggage transport vehicles, mainly because of the sea, otherwise the size of the force would have been even larger.

Of course, don't think that Han Xinjun, who had to reduce the corresponding supporting facilities in order to board the ship, was not affected, and after getting off the ship, the Lantian troops, who had not undergone a long time or had not undergone maritime training at all, more or less suffered from seasickness.

This effect was most affected by knights and crossbow chariot units, followed by heavy infantry and horses in baggage vehicles, and light infantry was the least affected.

After an urgent reintegration of the team, Han Shin was given a reduced force of nearly a third.

The attrition of the knights was the most severe, with only five hundred knights able to enter the queue and the belief that there should be no problem in participating in the battle.

Of course, this is not to say that the quality of these Qin army knights is very poor, on the contrary, except for a few knights who are really unable to fight, the other knights have the ability to continue fighting.

The main factor affecting the combat effectiveness of these knights is because of the transportation of these knights' war horses during this period of time, once they touch the ground, many of them directly lose their front hooves.

Faced with this kind of thing, Han Xin said that he underestimated the impact of sea transportation on war horses.

After a period of time, Zhang Jiashi, who knew about this situation, didn't quite understand why this problem happened, and finally had to consult the corresponding personnel of the Mo family and the farmer family to understand what the situation was.

That's how it works, and the pattern of the ships it transports has a great impact on the mounts in a hot and humid climate.

That is to say, these horses lose their combat ability for a period of time, seasickness is certainly a factor, but there are also reasons such as poor sanitation and illness.

It is for this reason that Zhang Jiashi, who thinks that he has ignored this situation, after thinking about it for a while, came up with a solution, that is, a building ship army, equipped with more than a dozen ships specially used to transport horses or livestock, this kind of ship is specially built, and the volume is much larger than that of the ship that transports personnel.

And the capacity of these ships, after the construction layout arrangement proposed by the farmer staff, is not too large. In an emergency, a transport ship that can only transport a hundred war horses at most makes Zhang Jiashi very helpless.

But there is no way around it. After all, transportation is not only based on the number of transportation, but also on the transportation weight, the weight of a hundred war horses has reached nearly eight or nine tons, and this weight is still very influential for wooden sailing ships.

This has also become the reason why this kind of transport ship, which is specially used to transport livestock, has to be equipped in large quantities.

This also made Zhang Jiashi have to think about the source of power, whether to make such a thing as a steam engine.

But Zhang Jiashi knows one thing very well, that is, even if he wants to build a steam engine, I am afraid that with current technology, he will not be able to support this.

......

It's just that Zhang Jiashi, who gave up the research and development of steam engines, did not expect that less than three hundred years later, the Great Qin Empire, which seemed to have embarked on the road of attaching too much importance to heavy industry in terms of scientific and technological development, finally developed a similar appearance to the Watt steam engine by Zhang Boyang, the ninth grandson of Zhang Ying, but was able to use coal as a power source.

The principle of the Watt steam engine is the cylinder and the reversing valve, the steam pushes the piston to do repeated movement in the cylinder, drives the flywheel to rotate through the connecting rod, and turns the reciprocating motion into a circular motion, and the flywheel in turn drives the reversing valve, changes the relationship between the intake and exhaust of the piston twice, and realizes the automatic reversal of the machinery to maintain the continuous operation of the machine.

The internal combustion engine designed by Zhang Boyang is similar to the operation principle of Watt's steam engine, but because the structure of the Watt steam engine is reduced, the kinetic energy of internal combustion is effectively used, and the overall output is improved, which has become a development curve that reduces this scientific and technological product.

After that, Zhang Boyang and people who have an understanding of this scientific and technological system or have a corresponding vision continue to improve the first generation of internal combustion engines developed by Zhang Boyang.

In May 156, 15 years after the introduction of the first generation of internal combustion engines, the new generation of internal combustion engines was considered to be a true piston internal combustion engine.

In a broad sense, the internal combustion engine not only includes the reciprocating piston internal combustion engine, rotary piston engine and free piston engine, but also includes the rotary impeller gas turbine, jet engine, etc., but the internal combustion engine usually refers to the piston internal combustion engine.

In the past, the resurrection piston type of piston engine was the most common. A piston internal combustion engine mixes fuel and air and burns it in its cylinders, releasing heat energy that produces high-temperature and high-pressure gas in the cylinders. The gas expansion pushes the piston to do work, and then outputs the mechanical work through the crank connecting rod mechanism or other mechanisms to drive the driven machinery to work.

The R&D personnel of this internal combustion engine are mainly Zhang Boyang, who has been committed to the development of this kind of device, and several of his disciples.

Of course, Zhang Boyang was able to develop this piston internal combustion engine, and the setbacks and failures he experienced were also not understandable to ordinary people.

He even lost his eldest son Zhang Weizhong and his son-in-law Deng Yang.

However, the emergence of this piston internal combustion engine became the most important turning point in the real scientific and technological reform of the Great Qin Empire.

Before the invention and popularization of this piston internal combustion engine, Zhang Jiashi has been committed to scientific and technological development and even invested heavily in this area. However, neither the achievements of agriculture nor light industry were able to reverse the level of major developments in productivity until the end of the year.

On the contrary, in terms of heavy industry, which was benchmarked against military projects, the heavy industry of the Great Qin Empire developed into a place where the Great Qin Empire had become transcendent from other technologies.

Of course, the emergence of this primitive first-generation piston internal combustion engine was still the first to discover its true value by the military.

A large number of piston internal combustion engines have become the sales destination of orders for the military and the corresponding industries.

And Zhang Boyang is very helpless, that is, as his distant cousin, or after Zhang Jiashi's death, he developed another family of Mo family as the son of Mo Zhongyuan, is from another batch of manuscripts left by Zhang Jiashi, combined with the piston internal combustion engine he produced, to create a vehicle that can really move forward and move with its own power.

In January 159 AD, this vehicle gradually evolved into an imperial necessity, with more and more advanced piston engines constantly appearing, and at the same time, in order to integrate this industry, although not a tyrant, but also difficult to be regarded as a Ming Emperor, Emperor Yingxi of Qin An made corresponding decree adjustments.

That is, he will allow this kind of industry, which involves many aspects, and even has the potential to jeopardize the basis of the empire's rule, to be regulated-based.

After this order was issued, the Great Qin Empire appeared in the following ten years, three major automatic vehicle manufacturing areas and five major engine manufacturing centers.

Of course, there are also many small and medium-sized corresponding manufacturing industries mainly scattered in some second- and third-tier cities in the core area of the Great Qin Empire.

These industries gradually raised the lifestyle of the Great Qin Empire to a higher level, especially after these technologies raised the overall scientific and technological level and national strength of the Great Qin Empire to a higher level, this time, the development of the scientific and technological level of the empire dominated by the internal combustion engine for a long time was called the first industrial technological revolution of the empire.

Of course, this method of being promoted by pulling out seedlings did not let Zhang Jiashi know, nor did it produce the kind of situation that plunged the Great Qin Empire into a crisis.

However, the emergence of this situation became the first full-scale crisis of the Great Qin Empire in the future, that is, in 460 AD, which can be said to have laid a very serious foreshadowing.

In the midst of the largest crisis the Great Qin Empire has faced since Qin II, which threatens to destroy the Great Qin Empire, the troops loyal to the Great Qin Empire fought against the rebels and rebels who swept through almost the core areas of the Great Qin Empire, using a large number of internal combustion engine vehicles.

This war consumed the strength accumulated by the Great Qin Empire for hundreds of years, and even lost the Iberian Peninsula region in the western part of the Great Qin Empire forever.

And with part of the foundation left by the Great Qin Empire's army after its defeat, these people who rebelled against the Great Qin Empire finally gradually narrowed the technological gap between the two sides.

And this may be an evolution of the situation that Zhang Jiashi could never have guessed.
