In the forward command post, Guo Bin was discussing the military situation with everyone, and suddenly heard the sound of horses' hooves outside, although there was no smoke and dust to be seen due to the muddy roads in spring, the shaking ground still showed that an extremely large cavalry force was galloping here. Not daring to slack off, Guo Bin and everyone hurriedly went out of the tent and climbed the hillside on the side of the valley to observe the enemy's situation.

The so-called people are ten thousand, boundless and shoreless. I saw a long dragon of cavalry winding in from the north, and the rumble of kicking the ground with horses' hooves unabashedly approached.

Just after the attack of the rear army was repelled by Zhang Fei several times, seeing that the sky was darkening, with the more than 1,000 Xianbei cavalry who came to Helian but did not enter the valley, some of them continued to attack the enemy with bows and arrows to delay the Han army, and the other part was separated and set up camp, and they made long-term preparations for rescue and Lian Shan Yu.

Moreover, if the original plan was followed, the Qianman army would follow closely behind the army and serve as a backup for the Helian army. Because the front army led by Helian had always marched lightly, carrying only three days' worth of food and grass, and all the equipment was used for field warfare, and besides, the army was full of combatants, so it moved extremely fast. The old and weak soldiers, who were mainly used as laborers, were all in the rear army led by Qian Man. Therefore, even the chieftains of the rear army did not deliberately delay, and the army could not march quickly.

However, after receiving the news that the army was ambushed and Da Dan was not known for his life and death, Qian Man urged the army to gallop all the way, and finally arrived at the mouth of the Thang Long Valley before nightfall. Fortunately, more than 1,000 people in the former army set up a camp at the mouth of the valley, otherwise the army would have arrived, and it would have taken a lot of effort to set up a camp, at least in the first half of the night.

Here, when the commanders of the Han army were instructing and explaining how the Xianbei soldiers came and how to set up camp in the observation post, the soldiers who were cleaning the battlefield behind had already quickly cleared a passage in the Thang Long Valley. After the passage was opened, the war materials in the rear were continuously transported, and along with these materials, there were 5,000 people.

Guo Bin had already discussed with Xi Zhicai before the war that a small city should be set up in the Thang Long Valley in the future to serve as a gateway for the Xianbei tribes in the north to enter and exit the Saiwai after the war. The purpose of the arrival of these 5,000 people was to urgently expand the camp at the northern entrance of Thang Long Valley overnight, so that it would have the scale and defense system of a small city.

Guo Bin led everyone to inspect the equipment, and when he saw a group of people on the hillside talking about a wooden instrument with an extremely long arm, he separated everyone and approached the past. When I saw it clearly, I couldn't help but sigh at the intimacy of Xi Zhicai.

This wooden instrument is a stone thrower. The ancient stone throwing machine was called "cannon", also known as the throwing car, the catapult, the thunderbolt car, etc., according to the source of the external force with the help of its projectile, it is divided into three kinds of manpower machine, torque machine and counterweight machine, and the earliest stone throwing machine that appeared in the Warring States period of our country is a human stone throwing machine that purely uses the pull power of people to throw.

This kind of stone throwing machine can be large or small, the advantage is that the structure is simple, the cost of manufacturing and maintenance is low, the disassembly and transportation are simple, it can be packed and loaded to the car like grain and grass, and the transportation is extremely convenient and labor-saving. However, its disadvantages are also very obvious, the structure is simple, the cost is low, which makes it easy to be imitated. In addition, because its projectile is purely human, it is extremely difficult to form a precise strike, because the number of people, the size and speed of the pulling arm are extremely uncertain, so it is difficult to hit accurate targets in the projectile.

Third, if you want to increase the lethality and killing range of this kind of stone throwing machine, you must increase its size and increase the number of operators. The arm of this type of stone throwing machine is called a tip, and the small stone throwing machine uses a single tip, while the large stone throwing machine uses a multi-tip one. The increase in the number of pins is nothing more than to increase the firmness on the basis of increasing their length, so as not to cause the pins to break during use. Legend has it that the largest trebuchet can reach 13 pins, and the corresponding number of operators is a staggering 500. Therefore, another disadvantage of this kind of stone throwing machine is that there are too many operators, the operation is difficult, and the requirements for the site are also very high.

At present, what Guo Bin has seen is a manpower stone throwing machine, because it is easy to transport and simple to make, so it was produced by the opera Zhi who sat in the three cities outside the Saiwai. Guo Bin and Xi Zhicai have a clear division of labor, Guo Bin is responsible for ambushing the vanguard of the Xianbei army to dampen the enemy's spirit, while Xi Zhicai is responsible for sitting in the three cities outside the Saiwai, while intensively arranging the defense work in the city, providing Guo Bin with the support of backup grain and grass. After all, if Guo Bin is defeated on the front line, there is still a place to retreat and hold on to help, and once there is an accident in the three cities outside the fortress, then Guo Bin's army outside will really be a turtle in an urn.

Originally, Guo Bin didn't expect to be able to ambush the most elite Da Dan Yu personal guard troops in the Xianbei army, but now it is an unexpected joy to be able to severely damage this army, and it is purely an accidental gift package to be able to kill Xianbei Da Dan Yu and Lian in front of the battle. Judging from the current situation, this counterattack aimed at resisting the attack of Xianbei Dadan Yu should be able to end early.

The Xianbei army was divided into eastern, central, and western routes to the south, and what Guo Bin and Xi Zhicai agreed was to concentrate their forces to break through the first road, and then stick to the three cities outside the city, and resist the attack of the other two armies under the city. After all, the Xianbei clan is good at field warfare, but they are really not good at siege warfare. Therefore, as long as the city is well stocked, even if there are no reinforcements from outside, it can be held steadily.

Now that he has received this unexpected big surprise from Helian, the layout of the entire battle will naturally have to be adjusted accordingly. There is no need to move the arrangement of the three cities outside the Saiwai to resist the two armies, but Guo Bin's task in the Shenglong Valley has been aggravated. His strategic goal has changed from delaying the Xianbei Middle Route army to the south, and harassing and hindering the march of its army along the way, to repelling the Xianbei Middle Route Army, basically building the Thang Long Valley Fortress, and quickly returning to the three outer cities after the battle, defeating the enemy under the city. Don't blame Guo Bin for running back and forth, it is really the elite troops under him who can fight at present, and there are only 700 elite troops that he brought over at the beginning.

The fortress at the northern entrance of Thang Long Valley, which has been hastily fortified, is made of logs of uniform thickness, which is far from the strength of a fortress on the scale of a small city. However, as long as the Xianbei Middle Road army is repulsed, the construction of the city can be slowly planned, and even handed over to Yangzhai Construction Co., Ltd. to undertake the construction after the war.

And the premise of everything is to repel the remaining 20,000 Xianbei middle road troops outside the valley.

Seeing that both the soldiers guarding the palace and the hard-working people looked excited, Su Shuang's admiration for Guo Bin spontaneously arose. He grew up in Zhongshan and began to work as an apprentice at a very young age. Later, I gradually started my own business, and it has been more than 20 years now. In the meantime, he traveled south and north, and asked himself well-informed. But he just can't understand Guo Bin, why is this young man who has not yet reached the crown so charming? He just made a speech in the three cities outside the city, and everyone bowed their heads, as if he could easily come up with an idea, which was a good idea in one fell swoop.

Just before the war, Guo Bin's words to the residents of the three cities outside the Saiwai, that is, the original Yellow Turban Army, were beyond Su Shuang's expectations, and the effect was unexpectedly good.

To say that Guo Bin once saved these people in the hands of the official army, they should be grateful, for the sake of the three cities outside the Saiwai, for Guo Bin to sell his strength, isn't this what should be shared? Moreover, Guo Bin is kind to them, and he should be shocked by the tiger's body, and Wang Ba's qi leaks, and these yellow scarf soldiers immediately bowed their heads and swore allegiance.

However, is it that simple?

Guo Bin was indeed kind to the vast majority of the nearly 500,000 residents of the three cities, and he had taken great risks to save the lives of these former Yellow Turban soldiers from being killed. But it is impossible for Guo Bin to publicize this kind of thing, otherwise it will become a favor to the people and ill-intentioned, and at the same time, he will offend Zhu Jun and even the entire Eastern Han Dynasty court officialdom. Therefore, the news that Guo Bin saved the lives of hundreds of thousands of yellow turbans may be circulating among the people, but the ordinary people do not know about it, and only high-level people on both sides such as Zhang Jiao and Huangfu Song know what happened.

In addition, in the eyes of many people, the reason why these Yellow Turban soldiers were exiled to the bitter cold land outside the Saiwai was all because of Guo Bin, and some corrupt Confucians even said that Guo Bin was brutal and inhumane, and regarded the Yellow Turban soldiers as goods for sale. Of course, this kind of extreme statement is not widely circulated, and the common people in the three cities outside the city cannot hear it. But after all, they live in the three cities outside the Saiwai, and the people they have to deal with every day are also Guo Bin's subordinates. Such frequent contact will inevitably lead to contradictions between the two sides, and although this contradiction is not a big deal, it will be magnified little by little in daily life, thus making the rift between the people and the government bigger and bigger.

There is no scenery in the so-called familiar place, and the same is true of politics. No matter how good the system is, no matter how comfortable the environment, it will cause people's dissatisfaction after a long time, which involves people's happiness. When a person is dying of hunger, when you give him a bowl of cold rice, he can lick the bottom of the bowl cleanly, so that he can burst with happiness. And when he arrives at the meal but does not eat, and you give him a bowl of cold rice, many people will think that you are inhumane and look down on others. Some people will cry out bitterly, that is "to beg for it", and then "beg for disdain", and some people will feel unhappy.

Therefore, the so-called happiness is just how you feel, and it does not have a fixed standard.

This is why some people wanted to oppose the Qing Dynasty and restore the Ming Dynasty during the Qing Dynasty, but when it came to the Republic of China, there were people who wanted to restore it. Putting aside the issue of nationality, it is not that the politics of the late Ming Dynasty were really much clearer than those of the early Qing Dynasty, nor that the Qing Dynasty was more orderly than the Republic of China, but that many people are dissatisfied with the status quo. Who doesn't know that it is really "anti-Qing", and the restoration will definitely not be "Ming", and if the restoration is really successful, it will no longer be the "Qing Dynasty" that has returned.

Therefore, the accumulated contradictions in daily life have already squeezed out the little favor of the residents of the three cities outside the Saiwai for Guo Bin, and Guo Bin wants to use these residents to resist the invasion of Xianbei Dadan Yu Helian, the first thing to do is to gain the support of the people, which is the most important problem that Guo Bin faced before this war.
