Of course, Zhao Hao's insistence on using the three-edged bayonet was not without considering the current situation, but blindly believing in the relevant 'legends' in his previous life, so he blindly insisted. The pen "fun" pavilion www.biquge.info said that the three-edged bayonet is not an invention of modern people. Pigwind. It is recorded in "Breaking the Axe": "Both break my axe, and lack my Qi (Yinqi)." Zhou Gong's Eastern Expedition, the Four Kingdoms are Qi", 錡, weapons, Qi blades such as chisels, equivalent to today's flat-headed three-edged military thorns. "Mao's Poems. QIN Feng. Xiao Rong": "The spear is the three-corner spear, which is the originator of the Chinese three-edged army.

It is true that the triangular spur also has many advantages, the saber is designed to kill, to have enough lethality, in addition to the weight, center of gravity, curve, sharpness, especially important is the severity of the wound and the difficulty of pulling out after the stab. They are all designed with different details to achieve the same purpose, so the body shape of the narrow front and wide back, the blood groove on the side of the blade, and the serration at the base of the blade are all present for this purpose.

The triangular spur is one of the most powerful sabers, which is also due to its structural shape. In addition to bloodletting, the blood groove is more important for the next action, if there is no blood tank, because the blood pressure and muscles contract violently, the thorn will be wrapped in the human body, so it will be difficult to pull out the thorn. The three-edged stab is that after the stab enters the human body, the blood is discharged with the three blood troughs, and when the muscles contract, they cannot "suck" the bayonet close to the bayonet surface, so that the bayonet can be calmly pulled out of the human body for the next step.

Then there is a three-edged spear puncture wound, which is generally a square hole, and the sides of the wound can not squeeze each other to achieve a certain hemostasis and healing effect, and this wound can not be bandaged and stopped during emergency treatment, and the bayonet pierces the opponent's body during the assassination and rotates the knife body, so that it will cause large-scale destruction of blood vessels and tissues. At the same time, air is quickly introduced through the blood trough, forming an air plug in the body and blocking the blood vessels. Therefore, it only needs to pierce about two inches into any part of the human body to kill the opponent instantly, so the lethality rate of triangular thorns is very high.

In addition, Zhao Yu has seen relevant historical materials about the weapons and equipment of the ancients in his previous life, and one of the posts analyzed the armor equipped at that time from the perspective of modern science, which now seems to be close to reality. Modern researchers have found the remains of many victims after the war through ancient battlefield archaeology, some of the dead did not have external injuries caused by slashing and spearing, and it is speculated that the death was caused by internal organ or bone damage, and there is evidence that they were all wearing heavy armor.

It can be guessed that the pure iron armor only has a protective effect on the bow and arrow or the bow and crossbow during the charge, especially in the cavalry charge, but the protection of the spear and knife only plays a superficial role in protecting the armor it wears, so that it cannot directly pierce the armor it wears, but the force of the heavy strike weapon held by the enemy is completely transmitted to the inside of the body through the iron armor, and finally causes damage to the internal organs or bones of the body and death.

The skins and iron armor of the Mongols were slightly different from the armor of pure iron in terms of surface protection. But he has a major characteristic, that is, when hit by a strong external force, as long as the opponent does not directly contact the armor by stabbing or picking, most of the force generated by the general slashing, sweeping and other methods is slowed down by the inner layer of leather armor in the iron armor, so that it protects the holder from internal injuries. It shows that in actual combat, the protective ability of the mixed armor made of animal skin is superior to that of all-iron armor.

Therefore, stabbing weapons had an advantage over percussive weapons against the Mongols, which was also the reason why the Song army re-chose spears. Of course, this is not to say that the triangular thorn has no shortcomings, it can only be used for assassination, at least it loses the possibility of multi-use. Another reason for Zhao Yu's choice is that the strength of the structure just now is not enough, and the bayonet is made into a triangular shape to improve the strength, which is less difficult to damage than the sword shape, and it is worth considering giving up some functions in terms of cost and killing effect.

However, Zhao Yu also knew that there were indeed practical difficulties in manufacturing three-edged bayonets in this era, and it was necessary to rely on manpower to build and shape little by little, while modern manufacturing of three-edged bayonets generally used extrusion method, and then carried out secondary processing and heat treatment. But at the moment, Zhao Yu knew that he couldn't make a hydraulic press with enough power, but he still thought of a feasible way.

In order to obtain the materials to make muskets, Zhao knew that it was necessary to improve the current methods of steelmaking, where only three technologies could be implemented to meet the needs of at least 200 years. These three technologies are: stirring iron-making method, which directly smelts wrought iron from pig iron; secondary smelting of cast iron and production of castings; Crucibles are made of steel, which is used to make knives.

The mixing method is mainly to stir molten pig iron on the hearth bed of a reverberatory furnace. The agitator constantly rotates and stirs the molten pig iron, which is decarburized by the circulating air in the furnace until it becomes malleable wrought iron. In this process, the metal does not come into contact with the raw coal used as fuel, and even the blower equipment is not required.

The disadvantage of the mixing method is that sand and gravel are used at the bottom of the mixing furnace. The silica in the sand and gravel is combined with iron oxide, and it is easy to form slag that is too acidic to absorb the phosphorus contained in pig iron refined from ordinary phosphate-containing iron ore. The need to repair the sand layer corroded by acid slag can reduce the production of the ironmaking furnace and cause considerable losses, and replacing the sand layer with a cast iron base plate can solve this problem.

After wrought iron is made, the next process is the manufacture of iron slats, Zhao Yu uses the method of hydraulic forging hammer, although it can only forge 2,000 catties of iron bars a day, but it is already a great invention in this era. After listening to Zhou Xiang's complaints, he also realized that this guy, who could always manage to complete his explanation, was really in trouble.

Under the pressure, Zhao Hao really came up with a method, that is, to use the grooved roll for the first forming, and this original rolling mill is not technically difficult for the present, this thing has appeared in Europe in the fifteenth and sixteenth centuries, but at that time it was mainly used for coinage, and now it is only necessary to change the cylindrical roll into a grooved roll. In this way, the bayonet blank can be rolled directly, and of course, the barrel stick blank can also be rolled by replacing the die, and this efficiency is many times higher than that of the hydraulic forging hammer.

Zhou Xiang heard that His Majesty had come up with a solution, so he immediately pestered His Majesty to draw the drawings, and immediately asked the craftsmen of the Imperial Supervisor to make a model, and then immediately went back to trial production, and assured Zhao Yu that even if the Spring Festival was not over, he would make the rolling mill to ensure that it could be put into production on time......

…………

Zhou Xiang's year is not going to pass, but Zhao Yu, as the head of the Great Song Dynasty, can't do it, and the necessary procedures still have to be followed. He first welcomed back the Queen Mother in Yazhou for the New Year, and the festivals arranged every day were endless, worshipping the sky, worshiping the earth, worshiping the ancestors, worshiping gods, and sacrificing ghosts. But fortunately, these things are handled by the ministers, and when the time comes, they only need to follow the shouts of the ceremonial officials, and the sacrificial texts have already been written, so they only need to read them according to the book and pull them down.

But these ceremonies are often long and boring, and with the time spent on the way, it takes most of the day to go out. Zhao Yu not only had to deal with urgent affairs, but also had to keep an eye on the war in the north, and also had to find time to compile teaching materials, supervise the preparations for the formation of the new army, and review the relevant materials they had collected and compiled. In this way, every day at the time of eating, I have to hold the scroll and read it while eating, and the time in bed can be two hours a day, it is often sleepy to squint on the soft couch, and in the morning I am called by Su Lan, changing clothes and washing in a daze, and I am about to board the car to participate in the event after eating.

Today is December 27th, and it is already Shen Shi when Zhao Yu returns to the palace after participating in the suburban festival, and it is already dark. He immediately changed into his crown clothes after arriving at the Tambo Pavilion, and went to the side hall to deal with the official documents after a little washing, and first took the battle report of the expedition to the north and read it carefully, the battle was as he expected, and the enemy soldiers who suffered heavy losses after the defeat were not able to redeploy their troops, and those temporary patchwork signing troops collapsed in an instant under the devastating attack of the northern army.

The vanguard led by Zhao Mengjin carried the naval warship upriver to conquer the Nanliu City, the capital of Yulin Prefecture, and captured Tianmen Pass. Jiang Cheng led the army to break into Rongzhou along the north stream, and if he went north, he could threaten Deqing Prefecture, and if he went south, he could encircle Gaozhou, Huazhou, and Leizhou in a roundabout way, cutting off the enemy's passage to the north. Now the armies have moved to rest and recuperate, punish the traitors and eliminate the evil, pacify the army and the people, and clean up the state and county treasury. Wen Tianxiang asked His Majesty whether to continue to attack northward, or to go south to collect the states.

Nanliu City is connected to the Leizhou Peninsula in the south, Qinzhou in the west, and is the key point of the seaway, which is an important place for soldiers in the past dynasties, and is an important transportation hub and commercial town in the southeast of Guangxi since ancient times, known as the "Lingnan Metropolis". Nanliu River in the Qin Dynasty to navigable, for the Central Plains to the south and Jiaozhi traffic arteries, the Western Han Dynasty has opened a trade route, can from the middle and lower reaches of the Yangtze River south to the Xiangjiang River, into the Ling Canal, turn the Li River through the Guijiang River to Wuzhou, and through the Xijiang River to Tengzhou, along the Beiliu River south to the north flow, and then by land from Tianmen Pass into Yulin, and finally along the Nanliu River to the south, in the Beibu Gulf to the sea.

Tianmen Mountain and Longgou Ridge two mountain ranges stand opposite each other, the mountain peaks are towering, to the Tianmen Pass is tight and narrow, become a key pass Tianmen Pass, also known as the Ghost Gate Pass, is the ancient and modern traffic artery. As long as they control this pass, they will choke the enemy's southward passage and block the enemy's reinforcements from Jinghu to the south, so that the Song army will seize the lead, and as long as the Tianmen Pass is not lost, they can calmly withdraw their troops.

Although the situation seems to be very good, according to the intelligence of the Affairs Bureau, Li Heng of the Guangdong Xuanwei Division has mobilized heavy troops to Deqing Mansion and gathered heavy troops in Wuzhou to prevent the Song army from continuing to move north; After Ali Hague fled to Qinzhou, he immediately asked the Zhennan Wangfu for reinforcements, and pleaded guilty to Dadu, and at the same time rectified the troops of Liuzhou, Xiangzhou, Binzhou, Yongzhou, and Qinzhou in Guizhou, hoping to recapture Yulin Prefecture; When Kublai Khan heard the news, he was furious, seized the title of Ali Hague, and ordered him to temporarily lead Zuo Cheng to recruit and suppress the Song army that went deep into Guangxi, and informed the Yunnan Xuanwei Division to send troops to reinforce it, and ordered the Liangjiang Xuanwei Division to levy and transfer 50,000 troops to restore the lost territory.

Zhao Yu knew that they were waiting for their orders, and they couldn't take a break, so they summoned Lu Xiufu, Liu Huang, Ying Jieyan and Liu Shiyong to meet and discuss, and the time of the others was not spared, and he took the official document sent by Zhongshu and read it. The first is the arrangement of the New Year's Day court meeting by the Ministry of Rites, the menu of the banquet and so on, and so on, he read them all at a glance.

In addition, those prisoners have been counted, and a total of more than 40,000 enemies have been captured in this battle, countless weapons and armor have been captured, and 6,000 war horses have been captured, but the property is not much. Liu Di, who was in charge of this matter, thought that the craftsmen in the captives could be selected and transferred to the capital courtyard, and the rest of the people were part of them into the baggage army, some of them were sent to the salt works, and the rest of the old and weak were sent to Yazhou Tuntian.

Zhao Yu saw that it was all arranged according to the old practice of the Shuaifu, and he wanted to follow it, but suddenly thought of something, and revised two more places. He ordered all the enemy generals above the centurion to be beheaded, leaving no one behind, so that they would not use their original influence to cause chaos. After all, the current army is fighting abroad, and the number of soldiers and prisoners left behind is similar, and it is always troublesome to cause trouble, so it is better to kill its leaders together to get rid of future troubles.

The reason why he arranged this way was because the Guangnan region was the last area to fall, and the old dynasty had not yet died, and the She soldiers gave strong support when they moved to the southeast, especially in the bloody night of Quanzhou, they had dispatched tens of thousands of volunteers, so they should be treated differently. Then there is the She nationality is a nomadic farming people, who have hunted and cultivated in the mountains for generations, and the folk customs are fierce and martial, according to the current saying, they are natural mountain infantry. In addition, in my previous life, I heard that there was a saying that the wolf soldiers in Guangxi were strong in the world, and it was more meaningful to use them for their own use than to let them plow the fields and dry salt.

After the instructions were completed, Zhao Yu took another list of meritorious and fallen soldiers who should be rewarded and bereaved in the defense battle counted by the Ministry of War. Behind it were some tribute lists sent by the state capitals, which he hastily read and put aside, and ordered them to be sent to the Empress Dowager's palace for her disposal.

After the approval was completed, Zhao Hao didn't have time to rest, and several of the governors who came in response to the edict also arrived. He could only brace himself up and discuss the next move of the Northern Army, and it could be seen from the battle report that Wen Tianxiang was very optimistic about the situation and wanted to make a tentative attack in the northeast direction. After reading the report of the secretariat, Lu Xiufu and the others believed that the next step should be cautious, not to rush forward, but to complete the roundabout gathering and annihilation of Gao, Hua, Lei and other prefectures as soon as possible, so as not to be surrounded and annihilated by the enemy. As for Wen Tianxiang's suggestion, they thought they could give it a try, but they had to be vigilant and retreat as soon as they found that they were in danger of being besieged......

"Official, don't work too hard, rest early!" After agreeing on various matters and sending everyone away Zhao Yu had dinner Su Lan saw that His Majesty was drowsy and stepped forward to say.

"In a little while, bring the information collected and compiled by the Imperial Front Office!" Zhao Yu shook his head, yawned, and rubbed his eyes.
