Crane top red, commonly known as arsenic # frost, is a highly toxic arsenic compound. The lethal dose of this compound is comparable to that of cyanide #. However, it cannot be rescued after poisoning cyanide # chemicals, but it can be rescued if it is found in time after poisoning arsenic # frost. The reason for this is the slow rate of action.

If arsenic is substituted into the organic chain and becomes a gas, the poison is dispersed in the air. Vinyl chloride chloride and arsenic chloride are only used for military purposes and have no medical use and are not found in nature. The toxicity is dozens of times that of mustard gas. Commonly known as the dew of death. However, the effect is not excellent because it is easily hydrolyzed. After hydrolysis, the toxicity is greatly reduced. However, after hydrolysis, the poison can cause severe blistering if it comes into contact with it.

There are only a few industrial agents, either containing phosphorus, arsenic, or chlorine elements. Now Ren Di's factory in the north is not just a raw material for the production of mustard gas and light # gas bombs. In addition to arsenic raw materials, there are fluorite (calcium fluoride) and phosphate rock, and from the point of view of the simplicity of the chemical formula, mustard gas is simple. More difficult ones, such as phosphorus methyloxydifluoride (sand # forest), can also be prepared.

A violent fire broke out near Shanhaiguan, and everything in this first pass in the world was washed under the burning # bombs fired by the Republican artillery, and mustard gas was combustible, which was also the fastest way to disinfect.

Shanhaiguan is the area where the Yanshan Mountains extend to the edge of the Bohai Sea, with mountains on one side and sea on the other, this pass is very narrow, and it has become the most important checkpoint in the northern capital area and the Northeast Asian continent. Shanhaiguan is located in the north of Bohai Bay, so the northwest of Shanhaiguan is Yanshan, less than five kilometers south is the sea, the Northeast Railway Line in this place by the sea, the whole line is almost close to the coastline. It is less than three kilometers away from the sea surface of Bohai Bay. Of course, the railway can only be repaired from here, and the picture on the 1990 red version of the Rendi plane on the one-dollar paper # coin has interpreted the majesty of the Badaling Great Wall built on the mountains, so the railway will not pass through the mountains from the inland.

The coastline in the north of Bohai Bay, which is diagonally northward, has been squeezed by mountain ranges, and only twenty or thirty kilometers close to the sea is a flat terrain, so that a corridor is formed The northwest side of the corridor is the continuous mountainous area, the southwest side is the Bohai Sea, this corridor is Qinhuangdao at one end, Jinzhou at the other end, and the famous Huludao naval base in the north is also on this corridor. That is to say, the only way to reach the Northeast from the flat area where Beijing is located is through this corridor between the mountains and the sea, and only when it reaches Jinzhou, can the railway get out of this threat from the sea and turn into the Great Plain of the Northeast.

And now the Hai Song fleet is swimming in the Bohai Bay. is the biggest threat to this railway line. Of course, if the port of Dalian Lushun on the Liaodong Peninsula is taken down. With the Shandong Peninsula, it can close the door to the Bohai Bay and fight dogs. Firmly hold the Bohai Bay. Of course, if you tear off another half towards the # Xian Peninsula, push the defense to the Yellow Sea. Beijing is much safer. It's a pity that Ren Di is sighing now. Zhao Weiguo did not have the technology to climb the ironclad ship, and he had a deep grudge.

If resentment could be turned into cannonballs, Xiao Xuan's fleet blocking Shanhaiguan would have sunk long ago. If this corridor is not completely taken, even if 100,000 troops enter the northeast, as long as the Hai Song Dynasty cuts off this corridor, the situation faced by the Republican army is the same as that of the Kuomintang army in the Liaoshen Campaign, which was closed and beaten after Jinzhou was taken.

Of course, this is also related to the fact that Wu Jiajun collapsed too quickly, if Wu Jiajun supported it for a longer time, for example, after the railway in Dongmeng was completed next year, such a scene of eating behind closed doors would not exist. But now, more than 100,000 troops of Hai Song arrived at the Liaodong Peninsula from the sea and began to take over the defense of the northeast. As a result, Ren Di had to face the problem of the corridor from Qinhuangdao to Jinzhou.

This strategic corridor is defended by the 16th Army of the Hai Song Dynasty, there are land supply lines and sea supply lines, and there are railway maneuvers on this railway, so the ammunition transportation equipment is very strong, not only the firepower on the land is strong, but also the support of the fleet ships and guns on the sea. One husband is a situation that is not opened. And there are layers of barbed wire front arming. The same as the iron wall.

So much so that Ren Di's northern command specially discussed this long and narrow strategy for a day, but there was really no way, the terrain was such that the strategy could not be carried out. The volume of material transport cannot be supplied for the consumption of modern armies. No amount of troops can be deployed.

In terms of military strength, Ren Di was now sufficient, and after the provinces south of the Great Wall were liberated by the Republican Army, a group of the original Imperial Army Zhuangding troops were reorganized. The total number of northern troops under Ren Di's control now reached 400,000.

Looking at a group of northern officers of the Republican Army, racking their brains to bother with this narrow terrain near the sea, at this time, the clerk who recorded on the side inadvertently interjected: "In fact, the supplies are a little lower, and we can also fight." "The speaker has no intention, and the listener has the intention. This clerk (Wang Tao) used to be a low-ranking officer in the Imperial Army. After ideological education, he joined the Republican Army.

War is a complex whole, and sometimes overthinking can overthink something else. The key to logistics is to determine the level of firepower that front-line soldiers put into it. The logistics line is admittedly important, but now Ren Di finds that his wave of people is shackled by the logistics line and judges the deployment of troops.

Ren Di walked up to this clerk Wang Tao and said, "We are a threat in the eyes of the enemy, right?" When the clerk saw Ren Di coming over, he couldn't help but regret that he had just interjected. I regret that I have nothing to do and talk too much. However, Ren Di asked, and in the face of Ren Di's question, the clerk couldn't help but nodded.

A machete in the hands of a well-mannered and bleeding man would not feel threatened by most people, but if it is a professional killer, even a shaving blade in his hand will make people's hairs stand on end. A warrior will never give up the act of stabbing an enemy in a duel just because the sword in his hand is inferior to the opponent.

It is true that the most convenient supply line channel is now strangled by Hai Song. The firepower of the army that enters the northeast to fight will be much weaker than that of the Hai Song, which now has aircraft, artillery, and armored trains. However, this does not mean that this kind of equipment superiority does not mean that the Republican Army will give up all strategic initiatives. If this is the case, everyone will not need to fight to compare equipment.

Ren Di once again set his sights on the unfinished Jitong line. The previous strategic focus was forced to shift because Hai Song appeared in Shanhaiguan to the republican army's Beiping general. Let the IRA desperately want to remove the threat from the North.

Turning around from Wang Tao, the clerk was left staring wide-eyed. Ren Di said: "It's a trouble for us to knock on the door in Shanhaiguan, but in other words, it's also a trouble for them to block the door here." Eat the meat first and then gnaw the bones. Troublesome things can be solved later. ”

He Wang also understood what Ren Di meant, and said: "Crossing the Great Khing'an Mountains into the northeast, our logistical support cannot support the passage of heavy weapons. It can only support the material consumption of 40,000 people, and it can only be light weapons and light mortars. ”

It was time to make a decision, and everyone once again focused on Ren Di. In a large battle, the General Staff will analyze all aspects as much as possible, but when it comes to such strategic decisions, only the commander-in-chief can make decisions.

Ren Di is no longer a rookie who has just crossed over, and this kind of decision is by no means the first time, nor is it the last. Ren Di smiled, with a firm and encouraging look in his eyes, he looked at the immature faces of the people present and said: "We have fought too smoothly this year, and even I myself have been a little flustered, and the enemies of the provinces in North China are vulnerable, and we will sweep away this mountain and river like a wind sweeping away leaves." The speed of this victory was too fast, and now we are facing this new battlefield and new enemy, which is enough for us to fight a whole day, so the strategy of formulating a strategy to solve the battle for several months at the beginning invisibly increases the difficulty of solving the problem. ”

Ren Di paused for a moment and said, "This is a protracted battle. A difficult start and then a gradual increase in our advantage. The war we are bound to win is not limited to the southern part of the Great Plain in the northeast. Hai Song thought that he could block Liaoning, a province along the Bohai Sea, with his own navy, and thought that he would be able to block us in the Guannai and digest this territory safely, and a few years later, the ceasefire created an established reality. They are also optimistic that our Jitong line will not be able to be repaired in two years. I want to grasp this strategic deployment time. ”

Ren Di smiled, dropped the pen and said, "Since this is the case, then I will accompany them in the Nenjiang Plain." ”

The battle meeting in Peiping decided that the 40,000 troops would carry out a thousand-mile leap, and this corps would cross the Great Khing'an Mountains and fight in this vast plain in the next year with inferior firepower and equipment and inferior troops. However, the strategic importance is also significant. If the current Liao is divided into three parts according to later generations, then Hai Song, which originally blocked the northern entry and exit of the Republic, now only gets Liaoning, which is close to the Bohai Sea. As for the Jilin and Heilongjiang basins in the northern part of the Great Plain sandwiched between the Great Khing'an Mountains and the Little Khing'an Mountains. You can't collect food, you can't dig mines. As long as Ren Di takes these 40,000 troops in the northeast, he will not be destroyed. The troops deployed by the Hai Song in North Asia always had to maintain the northern front. Tossing in the snow with Ren Di.

You must know that Hai Song's original strategy was to hold on to the Jitong line before it was repaired, to preemptively block the Republican Army in the south, and to engage the Republican Army in a few battles to dispel the power of the nascent republic to go north during this period and digest the entire Northeast.

In this way, the heavy troops that originally blocked the northward movement of the republican army at Shanhaiguan lost most of the significance of their blocking, and they had to maintain heavy troops at all times, which was equivalent to their own strength being also restrained. You can't go all out into the northeast and the Rendi mushroom tactical contest.

As for the current Hai Song Dynasty is very comfortable, they don't know Ren Di's determination to enter Northeast Asia, some times to enter Northeast Asia, is not a simple strategic analysis problem, nor is it determined by the difficulty of military operations, to a certain extent, this is a belief, from the belief of the great unification of China, the northern corner of the Chinese map is missing, Ren Di always feels that the place is wrong. Ren Di's worldview, which has been emphasized on territorial sovereignty since childhood, is different from the worldview of this generation of Hai Song veterans. Zhao Weiguo understood very well that he knew that Ren Di would complain about the difficulty of the Northeast Campaign, the lack of troops, and the poor logistics. But absolutely everything will be done to solve the Northeast campaign.

In the Council of Elders, Xiao Mingsheng, the patriarch of the Xiao family, and the patriarchs of Beiliang insisted on their own words, and the influence of the poison gas bomb seemed to be fading, as Xiao Xuanyun perfectly completed the task of transporting troops from the Chao # Xian Peninsula to the Liaodong region. After successfully blocking the Republican army from the Shanhaiguan area to the north, Hai Song's army quickly took over the Liaoning region. The Hai Song senators would shift the topic of discussion to how to complete the offensive on the republic on other routes.

And just when Hai Song Anran thought that he could eat the Northeast smoothly, ten days after the gas bomb time. The Republican counterattack came.
