Not to fight easily, it does not mean that you will not fight back and wait to be beaten.

The Black Turban Rebellion was largely due to the decline of the national strength of the princes, the slack of the army, and the failure to curb the domestic rebellion in the first place, and the rebels were beaten to the doorstep.

The fact that the defense of the country was short of two pounds and two wool from the Xianguo was just a change of form and means and a repackaging, and the essence was still to take economic aggression as the forerunner, and military and political pressure followed. War will break out sooner or later, but sooner or later.

The four of them chatted until dark, and in the evening, Jiang Qian prepared a banquet to entertain Bailiyan and Jiang Rong.

The next day, Bailiyan ordered Wei Qi to go to Lincheng to recall Sikong Nan to Guangxin, and at the same time accompanied Jiang Qian to inspect the north of Guangxin City and the port.

"Brother-in-law, you see, outside the north gate is the port and dock, after several years of expansion, now can berth more than 20 large ships of more than 10,000 stones, or dozens of 5,000 stone ships, if 20,000 stone ships are built in the future, they can also dock eight or nine, if they continue to expand, they will become the world's first male port in the future."

"Brother brother-in-law, don't be too happy, Guangxin is only more than 800 miles away from Chenling, if there is a strong enemy landing here in the future, I am worried that Guangxin will not be able to parry."

"How can it be, the Guangxin city wall is strong, and the black scarf is still helpless, not to mention how to break through the Guangxin copper wall from the sea."

"It's not my lie and threat, Guangxin is the best Tianliang port in the North Sea leading to the Jin Kingdom, and other ports are not conducive to the docking of large ships above 10,000 stones at the same time, so if there is a strong enemy from the sea in the future, Guangxin Port will be taken. Therefore, I suggest that at the same time as the fort fortress is built, the northern city wall of Guangxin should be heightened and thickened, and it should be thickened as much as it can. ”

Guangxin port is a rare natural deep-water port in the Beihai region, in recent years, the survey and survey, can basically confirm that the port, the average depth of the channel depth is more than six zhang, this depth of natural port is rare even in the world.

For the time being, not only large wooden warships can be berthed, but also steel warships and large aircraft carriers can be berthed in the future.

From the east coast of Changsun to the north coast of Jin Kingdom, the length of the coastline exceeds the sum of the coastline length of the west coast of the United States and Canada, and there are more than 40 large and small ports on the curved and stretching coastline.

There are only 12 ports that can provide more than 10 and dozens of 5,000 stone wooden ships to berth at the same time, and Guangxin is one of them, and only Guangxin and Chengang can be berthed by 10,000 stone ships.

The northern hemisphere is unknown Mingwen invaded southward, and if you want to invade the inland on a large scale, Guangxin is the only large-scale supply deep-water port, and you can capture Guangxin, and you will have no danger to defend Pingchuan in the south.

In view of the importance of Guangxin, the construction of the highest level of coastal defense forts and forts is a top priority.

Jiang Qian's vision is still limited to the war thinking of the era of land power, and the era of sea power will no longer regard the struggle for land as the only battlefield, and the defeat at sea will also face a long-term blockade and a point-and-click invasion and harassment anytime and anywhere.

After inspecting the city defense of Guangxin, Bailiyan rushed to the dock non-stop to understand the progress and inspect the combat readiness drill of the warship.

Due to the late construction of the large dock in Guangxin, the first 20,000 stone warship is still being built in Yongxing, but subject to the water depth and channel of the north section of the Yongxing River, it can only barely enter the territory of Changsun through the Milong River, and enter the North Sea through the inland river of Changsun, and then the 20,000 stone ships that have started construction will be built in the Guangxin dock.

In view of the serious shortage of warships above 10,000 stones, it is unable to compete with the civilization of the northern hemisphere at sea, and at the same time, Bailiyan has no intention of fighting a decisive battle with the enemy fleet in the far sea and deep sea, and it is the best policy to take advantage of the range advantage of shore fire artillery, combine sea and land, and hold the coastline. We cannot invest our limited naval forces in the face of a powerful opponent that is several times our size.

Benefiting from the iron price and the achievements of industrialized steelmaking, all the new Wanshi warships are temporarily equipped with Type 637 18 and 24 kg shipboard breech guns, equipped with smokeless gunpowder, and first practice sea tactics, and the new Type 645 platinum-based copper-nickel-iron-based alloy naval guns will replace the Type 637 guns within three to four years to enhance the firing range.

The new Type 645 gun will not only have a longer range, but will also use impact fire for the first time to shorten the firing time.

Traditional artillery uses a fire gate fuse to ignite the gunpowder in the breech, and there is a delay of several seconds or even more than ten seconds in the middle, which is not conducive to rapid shooting at sea.

The new Type 645 gun continues to follow the traditional tail fire door structure, but an external mechanical impact structure is installed on the fire door, and the impact fuse made of potassium chlorate mixed with magnesium powder and red phosphorus replaces the traditional delayed fuse, and the fire is transmitted and detonated under the impact of external force. Even if the hammer is damaged, it can still be detonated by manual impact or ignition.

Potassium chlorate is stable and is the best substitute for mercury, but it does not mean that mercury is useless.

The sensitivity of thundermercury has a countervailing effect on water, even if it is soaked in water, it can still detonate under the impact of thundermercury polymer, and even a trace of static electricity can be wiped out, so the impact agent made of thundermercury has strong detonation reliability and is suitable for triggering in rudimentary weapons and harsh environments.

In the afternoon of the same day, Sikong Nan rushed back to the official residence of Sima Cheng Mansion in Guangxin from Lincheng, and after Lincheng was included in the Guangxin Defense Zone, Sikong Nan stayed in Lincheng for half of the time.

It's not that bandits are rampant in the area, but mainly because the intelligence activities of other princes are rampant, and the royal guests are only responsible for surveillance and intelligence, and the garrison is still responsible for security affairs.

"Brother Sikong hasn't seen you for a long time, and you haven't been harmed in recent years."

"It's all thanks to the blessing of the Hou Ye, everything is fine. It is after the establishment of Lincheng, there are a lot of thieves, a little slack, was taken advantage of by the thieves, I also just went to Lincheng five days ago, Hou Ye is here for Guangxin Gong. ”

"Well, one is for my father-in-law, and the other is for Guangxin city defense. The king will soon build a large number of buildings in various places, the city defense fortress is the top priority, and Guangxin port is related to our only naval port, and the safety of the Lingling is the focus of the fortress, so he urgently summoned to meet to discuss this matter. ”

"With all due respect, Guangxin City is strong and deep, and there are naval guns stationed in it, looking at the Central Plains, there is no country in the Central Plains where our salty navy is strong, and the last general really can't think of why it can be attacked from the sea."

"Brother Sikong doesn't have to ask about this matter, Ben Hou always has a reason to be in it. You are stationed here, you must be on guard, I am too busy with official business to come here from time to time, so during the construction of the local fortress fort, you must keep an eye on Ben Hou.

The cement produced in Lincheng and the appropriation from the state treasury will be given priority to supply Guangxin, and the fortress must be built within two to three years to make it usable. ”

"It's so urgent."

"It's not that this Hou is in a hurry, it's the situation that is compelling. In addition to the construction of fortress forts, air-raid shelters and underground bunkers should also be dug in the city to meet the needs of at least 50,000 people for concealment, which can be completed more slowly in five to six years. ”

"Shhh...... But there are no flying eagles in the land of the North Sea. ”

"Did Brother Sikong ever think about what would happen if it was an artillery bombardment or a hot air balloon strike, and the projectiles would fall into the city?"

"This is also true, and now artillery is everywhere, dozens and hundreds of artillery shells are bombarded with solid lead pellets, and the brick-clad city wall is still unable to parry, and the adobe city wall is even more useless. Alas...... The world has changed. The last general is old and useless......"

"Brother Sikong doesn't have to be like this, I'm also prepared just in case."

"What Hou Ye said is true. The last general often heard Chen and Luo say that the current defense of the country is dominant, and there is gradually a tendency to unify the Central Plains from west to east, the eldest grandson in the north is weak, if the eldest grandson dies, the next turn will be Xianguo, and the last general really does not know that he can see a few years of peace in his lifetime. ”

"Hehe, Wei Guoxiao is not a matter of concern." Bai Liyan said disdainfully, and then said: "I might as well tell Brother Sikong a piece of news, and if I say it, I will scare the country to death." ”

"The last general would like to hear about it."

Baili Yan stood up and approached Sikong Nan and whispered:

"Last year, Yongxing City has built a new type of artillery, six catties of artillery can go as far as eight miles, and eighteen catties of artillery can send projectiles to fifteen miles as far as possible.

Sikong Nan was taken aback when he heard the news:

"This, this six-pound cannon could only send projectiles one and a half miles away, but now it can really reach eight miles!"

"It's true, you can shoot eight miles."

There is a world of difference between the performance of carbon steel and alloys, as far as the performance of platinum-based copper-nickel-iron-based alloys is concerned, the firing range of the six-kilogram projectile breech gun is not surprising, less than four kilometers, and only the higher the chamber pressure, the more propellant the gun can be loaded.

If it can be forged, heat treated, and then remelted with electroslag, and the tube body is self-tightened, the firing range of a breech-loading cannon howitzer of forty or fifty mm caliber will be longer, and even a recoilless gun can easily hit seven kilometers.

Of course, if you don't consider the weight of the artillery, you can blindly increase the weight and wall thickness and push the firing range, but for the breech guns that lack accuracy, it doesn't matter if it is eight miles or fifteen miles, even if it can hit 30 kilometers, it doesn't mean much to a solid projectile, and the key is still in the projectile.

In the absence of accuracy, fragmentation, shrapnel, and explosive shells are more important than the range of the artillery itself.

Cluster-type surface killing,It's more efficient than a simple point kill,Even if the accuracy is so bad,Sufficient barrage density can still make up for the lack of accuracy,Sikong Nan was only frightened by the range of those eight miles,But I don't know that the real power is the projectile。

The matter of Guangxin Fortress was agreed with them, and the two went out of the city to inspect the landform on the second day, and then Bailiyan rushed to Lincheng non-stop for a few days to inspect the chemical, cement, petrochemical fuel and other workshops, and make adjustments to the expansion of ether and cement production.

Ether and laughing gas are the earliest anesthetics, long-term use of large doses can be addictive, mandala, mazegrass, small shaozi, betel nut, Lexian fruit can extract hallucinogenic and anesthetic active ingredients, Bailiyan suspects that pain fever is a malignant disease that attacks the central nervous system, most likely caused by an unknown virus, the main source of genetic defects in Jinxuedi people or prone to pain and fever.

At least during the Bailiyan Southern Expedition, many cases of Jinxuedi people suffering from pain and heat were found to have died violently, but there were almost no cases of people in the Central Plains being infected.

The fact that hallucinogens have a calming and paralyzing effect on the nervous system and can cure pain fever means that it is not the other ingredients in the herb that work, but the hallucinogenic anesthetic that prevents the spread of the virus to the brain, which means that ether and all other chemical anesthetics can produce a curative effect.

Of course, it was not Bailiyan who was merciful and compassionate.

On the contrary, if ether is feasible, it means that Zhongyuan has a drug that can control the Jinxuedi people in large doses. At the same time, it is not ruled out that the strain of pain fever will mutate on a day and enhance its infectivity to invade the Central Plains human race. Mooney's trip also does not guarantee that his entourage did not carry disease-causing strains, and it is better to prevent the disease than to be prepared at all.
