I don't know where Luo Songting came from this picture, but even the well-informed Bailiyan (Wei Xian), who has been well-informed in the two lives, was also surprised.

According to Luo Songting's own words, this kind of hem trebuchet, according to the size of the difference, the weight of the stone is different, the farthest can throw a ten-pound stone out of 400 steps, and the nearest can be 100 pounds of ten pieces weighing 200 steps away, far beyond any kind of catapult device nowadays, and extremely saving manpower.

At the same time, the shortcomings are also very bad, and the preparatory work in the early stage is very labor-intensive, especially the construction of the earth platform, which is extremely labor-intensive. In addition, it cannot be moved, but can only be used fixedly.

Once this kind of hem trebuchet is built, even if the Black Turban Army on the other side of the river throws oil barrels, as long as they fight back, it will ensure that there will be no Black Turban soldiers within a mile of land.

According to the plan, this kind of hem trebuchet is lined up to build 20 units first, the man-hours can not be calculated, the first batch is caused, and then built from near and far one after another, the number is not capped, the more the better. At that time, the entire Wuping coast will be covered with such hem trebuchets, attacking day and night, which can completely block the Black Turban Army from a mile away from the river bank.

On the second day, Jiang Qian and Zhong Heng each transferred 2,000 people to go to the wood, and another 4,000 people were drawn to build the mound, preparing to organize craftsmen to build this kind of hem trebuchet.

Bailiyan led 1,000 men and horses from his headquarters, and Zhong Heng transferred another 2,000 men, a total of 3,000 people, to dig the first arson ditch and drainage ditch along the camp. First, to prevent the Black Turban Army from throwing oil across the bank, and blocking it with a fire ditch.

You can let the oil enter the ditch along the ground, bury it and extinguish the fire by turning the soil, and you can also use the fire ditch to collect oil. The fire ditch is one and a half meters wide and one meter deep, and it takes ten days and half a month to dig more than ten miles of land.

The three armies of the Black Turban Army arrived on the banks of the Yongxing River one after another, and the company camped for hundreds of miles, and the body was as long as ten miles, which inevitably reminded people of Lu Xun burning the company camp.

However, the Black Turban Army is not a stupid hat, the camps are all endless farmland, and they are next to the Yongxing River, only they have the share of burning the Yongxing River, and there is no possibility of the salty army burning them.

Soon after the Black Turban Army of more than 500,000 horses and horses camped, it tentatively attacked the passes of the Xian Army along the upper and lower reaches of the Yongxing River, and Wuping, as the narrowest part of the whole river section, bore the brunt.

It's a pity that the Guangxin army guarding Wuping is not a fuel-efficient lamp, and the black turban army sent people to cross the river at night to try, how did they expect that Bailiyan buried a large number of simple animal traps under the beach along the defense area, and the result can be imagined, and it is a trivial matter to break the leg after a scream, and it will cause an overwhelming rain of arrows to kill.

The trap is made of bamboo and wood, and the copper sheet is the spring, which is buried under the sand, and there is no way to detect it, and it can be produced in large quantities. Then he was implicated with ropes, which were also buried in the ground. If you want to cross the river one day, you can just drag it out, or you can check and replace it regularly.

However, the trap is only a temporary measure, and if the Black Turban Army is tired and spreads planks on the ground, they can still get by, so it is only a temporary measure to supplement, and it is by no means a long-term solution.

Within five days after the Black Turban Army set up camp, the scale of the camp was a few hundred people and the largest was 10,000 people. According to the confession of the captured black turban soldiers, the military system of the black turban army is extremely simple, with only four military ranks: Shi Commander, Centurion, Thousand Commander, and Ten Thousand Commanders.

The soldiers of the Black Turban Army are also eye-opening, including those of Xianguo, Sun Guo, Zhiguo, Changsun Guo, Xu State, Yan State, Weiguo, and even Jin people who came from afar, which can be called the army of all nations.

100% of the personnel are peasants, tenants, untouchables, slaves, and to put it bluntly, they are all the low-level toiling masses most disregarded by the powerful and nobles.

According to this statement, the infiltration of the Black Turban Army has reached the point of pervasiveness, and there are people who have traveled thousands of miles to defend the country in the West Sea and the Jin Kingdom in the East China Sea.

In addition, the equipment is also varied, in addition to the Jin State and the Song State of the Central Plains, they have weapons and armor from other countries, and the Sun State and the Xian State have the most equipment.

The Black Turban Army that attacked the capital this time was really 500,000 soldiers, and the blade equipment rate was 100 percent, but the bronze blades were the majority, and the armor rate was 60%, and there were 200,000 people who did not even have light leather armor, but the Black Turban Army still gathered 80,000 heavy armor troops and nearly 70,000 miscellaneous cavalry. According to this calculation, the 2.67 million miscellaneous Xian army, even the 80,000 heavy armored army and 70,000 cavalry of the Black Turban Army could not deal with it.

Zhao Xun only had a total of 30,000 heavy armored troops, 50,000 infantry riding pack horses, war horses, and horses, and the Black Turban Army only needed to dispatch 250,000 horses to wipe out the Xian army.

Even if most of the captives have water, even if they are only half of the number, they are not comparable to the Xian army. The Black Turban Army had no warships, nor did they have enough boats, so it was difficult to cross the river for a while.

But at this time, everyone thought of another fatal problem, it is now June, July is the dry season of the Yongxing River, the depth of the water is only seven or eight meters, the shallow place of the water is less than one zhang, the black turban army only disturbs the river at this time, and the river water may be lower in case of drought, this is not clearly waiting until the water level drops in July, and the river will be covered with soil and fill the river!

Time blink of an eye into the middle of June, the weather is getting hotter and hotter, Jiang Min stayed in the Lingling for nearly a month, and returned to the army with the reward of King Xian. At this time, Luo Songting's pendulum trebuchet had been built, and even Bailiyan praised it for its lethality.

On this day, Baili Yan just fell and buried the body of the Black Turban Army, and Luo Songting came to ask:

"Wei Xianfeng, just now the Chinese army came to give an order, the water depth of the Yongxing River from July to September is half lower, so that all armies will strengthen their vigilance."

"Well, last night, I personally fell into the middle of the river to explore the depth, the depth of the river was less than two zhang, and the water depth was still two zhang and seven feet when I first came. If this continues, the depth of the Wuping River in July will probably be less than a zhang, in case the Black Turban Army covers the earth and fills the river, and takes the opportunity to kill on a large scale, our army will only have 30,000 people, and I am afraid that we will not be able to parry. ”

"The Lord is just worried about this matter, and General Zhong Heng has been summoned to discuss."

Although Luo Songting's hem trebuchet drove the Black Turban Army out of the west bank for a mile, if the river was low enough to be blocked with foreign objects, the Black Turban Army would fill in the section of the Wuping River with dead people, and then kill tens of thousands of people in one go, and it would not be able to hold it.

"Senior Luo has a plan?"

"I thought that as long as the Black Turban Army could not cross the river and hold on for a long time, the Xian Army would be able to accumulate strength and fight against it. It seems that he still underestimated the wisdom of the Black Turban Army, and he never expected the Black Turban Army to have such a poisonous plan. ”

Bai Liyan was puzzled, and he said:

"Senior Luo, since the generals of our army can think of it, the Black Turban Army can naturally also think of it, if our army knows that the Black Turban Army has this intention, it must stick to the camp and mobilize reinforcements as soon as possible.

It is now the middle of June, and the total number of troops from all walks of life exceeds 320,000, and by July, our army will always have 400,000 miscellaneous troops. And our army sticks to the east bank with a camp as a screen, even if the 500,000 Black Turban Army pours out, our army takes the defensive, the 500,000 Black Turban Army does not have an absolute advantage, if it is attacked, the Black Turban Army will be able to defeat our army at a huge cost.

Although our army was defeated, it was not completely annihilated, and it was almost wishful thinking that the remaining remnants of the Black Turban Army wanted to capture the Lingling before the autumn. At that time, the main force of the Jin army withdrew from Qiguo and landed in Beihai County to the south, and the Black Turban Army still had many chances of winning. ”

"Wei Xianfeng means that the Black Turban Army will not cover the earth and fill the river?" Luo Songting was surprised, at least he thought that this might be extremely high.

"It's not impossible, it's just that we can't completely annihilate our army, which is extremely disadvantageous to the Black Turban Army. I thought that the Black Turban Army must be planning a big battle to annihilate our army, but it could completely annihilate our 400,000 troops in one fell swoop. ”

Luo Songting's expression was clearly unbelieving, he said:

"The east bank of the Yongxing River is all choked by our army, and the Black Turban Army can't go around and sneak attack behind it, how can it be like the Lu Ji army, flanking me back and forth."

As soon as Luo Songting's voice fell, the herald came galloping on horseback:

"Mr. Luo, Wei Xianfeng, urgent news from the Chinese army, the lord will quickly order the two to return to the camp."

The herald repeated, turning around randomly and going elsewhere.

Bailiyan didn't dare to delay, and rushed to the big tent with Luo Songting, Jiang Gan, Wang Jiu, Hu Mo and others had already arrived, and Zhong Heng and the generals also came.

"Lord, I don't know what news the Chinese army is?" Luo Songting asked first.

Zhong Heng frowned and said:

"Zhao Shuai just sent news that a few days ago, the other side of the strait came to report and found that the Black Turban Army was preparing cotton clothes. It seems to be ...... It seems to be preparing for the winter. ”

Luo Songting was incredulous when he heard the news:

"Winter? This can't be, the single clothes of the capital county in winter can still keep out the cold, and the black scarf army wears cotton clothes. ”

Zhong Heng continued:

"According to reliable sources, cotton clothes have been distributed to every black turban soldier, and if it is not for the winter, it will not make sense to ask for cotton clothes."

At this time, Bailiyan said with a calm face:

"It is not important for the black turban army to wear cotton clothes, the important thing now is that the Xianguo is not cold in winter, and the Xianguo country does not prepare cotton clothes eight or nine times out of ten, if the temperature drops sharply at this time, where will our army get cotton clothes."

Xianguo is not cold in winter, except for Jiangdong County, most places are above zero seven or eight degrees, so cotton clothes are never prepared. In winter, you only need to wear a slightly thicker robe to keep out the cold, and in Beihai County, men and women even only need to wear straight robes and neon clothes to meet the needs of thermal insulation, so in addition to the rich and powerful, almost no one in Xianguo has prepared cotton clothes.

The Black Turban Army came all the way from Sun Kingdom, the latitude of Sun Country was higher than that of Xian Kingdom, and there was snow in the south in winter, so the Black Turban Army got hundreds of thousands of cotton clothes.

June is already very hot, the temperature is less than 344 or 5 degrees, and the black scarf army has a cotton coat in hand at this time, which is absolutely groundless.

At this time, Bai Liyan only thought of Jiang Ziya's war back then, and he had done it on the mountain, and he froze to death the 100,000 merchant army overnight. Although it is only a legend, it is not impossible to analyze it in theory.

As long as there are enough cumulonimbus clouds to create super hot and cold convection, it is possible to force a large number of ice crystals hovering high to snow and hail. The intensity of the convection will directly determine the cooling and snow intensity.

Theoretically, the hotter the weather, the thicker the clouds in the sky, the less it rains, and the higher the probability of snow under super convective weather. When the temperature drops to a certain range, the hot air continues to strengthen, and the further cooling amplitude increases, and finally a local atmospheric circulation is formed.

It is not difficult to do this, you have to choose a mountain that is high enough to light a fire at a certain height from the clouds, a very, very large fire.

But how can the Black Turban Army grasp the recent meteorological conditions, it can't be a whimsical way to open the altar and let it snow, right? Unless it is a god like Jiang Ziya, who can pinch and calculate, or at least someone who knows the solar terms well, has already seen some scientific laws.

If this is the case, even if the Xianjun believes that it will snow at this time, they will not be able to get cotton clothes, and more than 300,000 people will have to freeze to death.

[Regardless of whether Jiang Ziya opened the altar or not, whether it was true or false that the snow froze to death the Shang army, as far as the facts are concerned, the climate of the Yellow River Basin in the Xia and Shang periods is comparable to today's GD, extremely warm all year round, almost no winter, during the period of the Yellow Emperor Yandi, the entire Yellow River Basin is a whole subtropical, which is extremely suitable for human survival. The climate of the Yellow River basin began to change drastically during the Zhou Dynasty, and it was also during this period that the nomadic peoples in the north began to move south in contact with the Central Plains due to the southward shift of the 400 mm precipitation line on the Mongolian Plateau. 】
