Crane red, commonly known as arsenic frost, is a highly toxic arsenic compound. The lethal amount of this compound is equivalent to that of cyanide. However, it cannot be rescued after poisoning cyanide. After poisoning arsenic frost, it can be rescued after being poisoned. The reason is that the action speed is slow.

If arsenic is substituted into the organic chain and becomes a gas, it will spread in the air. Vinyl chloride, arsenic chloride is only used for military purposes and has no medical uses, and it will not be seen in nature. The toxicity is dozens of times that of mustard gas. It is commonly known as the dew of death. However, the effect is not excellent because it is easy to hydrolyze. The toxicity is greatly reduced after hydrolysis. However, if the poison is exposed to it, it will cause severe blister burning.

There are only a few types of industrial poisons, either containing phosphorus, arsenic, or chlorine. Now Rendi’s factory in the north is not just a raw material for producing mustard gas and light# gas bombs. In addition to the arsenic raw materials, there are fluorite (calcium fluoride) and phosphate ore. From the simplicity of the chemical formula, mustard gas is simple. For example, methyloxygen phosphorus difluoride (sand# forest), you can also try to prepare it.

A violent fire broke out near Shanhaiguan. Everything in the world's No. 1 level was washed under the burning bullets fired by the Republican artillery. Mustard gas is combustible, which is also the fastest way to disinfect.

Shanhaiguan is a zone where the Yanshan Mountains extend to the edge of the Bohai Sea. On one side is mountains and on the other side is sea. This pass is very narrow and has become the most important pass in the Beidu region and Northeast Asia. Shanhaiguan is located in the northern part of the Bohai Bay, so the northwest of Shanhaiguan is Yanshan, and the sea is less than five kilometers south. The Northeast Railway Line is by the sea here, and the entire line is almost adjacent to the coastline. It is less than three kilometers away from the Bohai Bay sea surface. Of course, the railway can only be built from here. The picture on the 1990 red version of the Rendi Plane 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 slanted northward coastline in the northern part of the Bohai Bay has been squeezed by mountains. Only twenty or thirty kilometers near the seaside can it be flat terrain. This forms a corridor. The northwest of the corridor is a continuous mountainous area, and the southwest is the Bohai Sea. On one end of this corridor is Qinhuangdao and Jinzhou at the other end. The famous Huludao Naval Base in the north is also on this corridor. In other words, from the flat area where Beijing is located, it can only pass through the corridor between the mountains and the sea. Only by reaching Jinzhou can the railway escape from this threat from the sea and turn to the Northeast Plain.

And now the Haisong fleet roaming in the Bohai Bay is the biggest threat to this railway line. Of course, if the Dalian Lushun Port on the Liaodong Peninsula is taken down and cooperate with the Shandong Peninsula, you can close the door and fight dogs against the Bohai Bay and firmly guard the Bohai Bay. Of course, if the North Korean Peninsula tear down half of the defense and push the defense to the Yellow Sea, Beijing will be safer. Unfortunately, Ren Di is now sighing. He has deep resentment towards Zhao Weiguo without the technology for climbing the ironclad ship.

If resentment could be turned into shells, Xiao Xuan's fleet that blocked Shanhaiguan would have been sank long ago. If this corridor was not completely taken down, even if 100,000 troops entered the Northeast, as long as Haisong cut off this corridor, the situation faced by the Republican Army would be the same as the situation where the Kuomintang army faced the situation after being captured by Jinzhou during the Liaoshen Campaign.

Of course, this is also related to the collapse of the Wu family army too quickly. If the Wu family army supports it for a longer time, for example, after the East Mongolian Railway is completed next year, such a scene of being turned away will not exist. But now, more than 100,000 troops of Haisong arrived at the Liaodong Peninsula from the sea to take over the Northeast defense, which led to Ren Di having to face the problem of the Qinhuangdao to Jinzhou entering Liaoning.

The defense of the 16th Army of Haisong in this strategic walkway is the land supply line and sea supply line. There is railway maneuver on this railway, so the ammunition transportation equipment is very powerful. Not only is the firepower on the land, there are also fleet naval gun support on the sea surface. It is a situation where a man is at the silo of thousands of men. And there are layers of barbed wire mesh line defense, like a copper wall.

So much so that the Rendi Northern Command specially discussed this narrow strategy for a day, but there was no way. The terrain was so terrain that the big roundabout strategy could not be developed. The material transportation volume could not be provided for the consumption of modern troops. No matter how much force could be developed, it could not be developed.

In terms of military strength, Ren Di is now enough. After the provinces south of the Great Wall were liberated by the Republican army, teams of the original imperial army were reorganized. Now the total number of northern troops controlled by Ren Di reached 400,000.

Looking at the northern officers of the Republican Army, racking their brains to the narrow and sea-locking terrain, the clerk who was recording on the side accidentally interrupted: "In fact, we can fight with a lower material supply." The speaker was unintentional and the listener was intentional. The clerk (Wang Tao) was once a low-level officer of the Imperial Army. He joined the Republican Army through ideological education.

War is a complex whole. Sometimes excessive consideration may ignore other things. The key to logistics is to determine the degree of firepower deployed by frontline soldiers. The logistics line is indeed important, but now Ren Di finds that this wave of people is shackled by the logistics line and the judgment of the deployment of troops.

Ren Di walked to the clerk Wang Tao and said, "We are threatening 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 interrupted. He regretted that he had nothing to do. However, Ren Di asked, and in the face of Ren Di's questions, the clerk couldn't help but nodded.

A machete is placed in the hands of a gentle and blood-drowning person, most people cannot feel the threat. However, if it is a professional killer, even if there is only a shaved blade in his hand, it will make people stand up. A warrior will never give up the action of stabbing the enemy in the duel just because the sword in his hand is worse than the other party.

It is true that the most convenient supply line channel is strangled to death by Hai Song. The firepower of the army entering the Northeast will be much weaker than that of Hai Song, who now has aircraft, cannons and armored trains. However, this does not mean that this equipment advantage does not mean that the Republican Army will give up all strategic initiatives. If this is true, everyone will not have to fight and compare equipment.

Ren Di once again turned his attention to the unfinished Jitong Line. His previous strategic gaze was forced to shift because Hai Song appeared at Shanhaiguan to attack the Republican Army's Beiping, which made the Republican Army anxious to remove the threat from the north.

Turning around from Wang Tao, the clerk left behind the clerk staring. Ren Di said: "It is a problem for us to knock on the door in Shanhaiguan, but in other words, it is also a problem for them to block the door here. Eat meat first and then chew bones. Trouble things can be solved later."

He Wang also understood Ren Di's meaning and said: "When we crossed the Greater Xing'an Mountains and entered the Northeast, our logistics support cannot support the past of heavy weapons. We 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 set their sights on Rendi. In a large battle, the General Staff will analyze all aspects as much as possible, but when such a strategic decision is made, only the Commander-in-Chief can make a decision.

Ren Di is no longer a rookie who has just traveled through time. This kind of decision is definitely not the first time, nor is it the last time. Ren Di smiled, with a firm and encouraging look in his eyes and looked at the tender faces present and said, "We have fought so smoothly this year, and even I am a little erratic. The enemies of the provinces in North China are vulnerable. We cleaned the mountains and rivers like a gust of wind swept away fallen leaves. The speed of victory is too fast, and the new enemies we are facing now are enough for us to fight, so we first formulated a strategy to solve the battle for several months, which invisibly increased the difficulty of solving the problem."

Ren Di paused and said word by word: "This is a protracted war. A difficult beginning, and then gradually increased with our advantage. We will definitely win the war. The entire Northeast Plain is not only where Shenyang is in the south. Hai Song thought that he had stuck Liaoning, a province along the Bohai Sea with his navy, so he thought that he could block us in the pass and digest this territory safely. A few years later, the ceasefire created a certain reality. They were also optimistic that our Jitong Line would not be completed in less than two years. They wanted to seize this strategic deployment time."

Ren Di smiled, threw down his pen and said, "Since that's the case, then I'll spend a fight with them in the Nenjiang Plain."

The combat conference in Peiping decided that 40,000 troops would carry out a thousand-mile leap. This legion would cross the Great Xing'an Mountains and would fight in this vast plain with inferior firepower and equipment and inferior troops in the next year. However, the strategic significance was also very important. If the current Liao area was divided into three parts of Heiji and Liao according to later generations, then Haisong, which originally blocked the northward entry and exit of the Republic, now only gets Liaoning near the Bohai Sea. As for the Jilin and Heilongjiang basins in the northern part of the Great Xing'an Mountains and the Little Xing'an Mountains, they could not conquer food or dig mines. As long as Ren Di led these 40,000 troops to immortalize in the Northeast, the army sent by Haisong in North Asia would always maintain the northern front line and fight with Ren Di in the snow.

You should know that Hai Song’s original strategy was to support the Jitong Line to stop the Republican Army in the south before it was repaired, and to fight with the Republican Army for several battles to dispel the power of the newborn Republic to the north during this period and digest the entire Northeast.

In this way, the heavy troops originally blocked the Republican army from Shanhaiguan to the north would lose most of the meaning of blocking them, and they would always maintain heavy troops, which would mean that their own troops would be restrained. They could not devote all their efforts to tactical competition between the northeast and Rendi Mushrooms.

As for Hai Song now, they didn't know that Ren Di's determination to enter Northeast Asia. Sometimes entering Northeast Asia is not simply a strategic analysis problem, nor is it determined by the difficulty of military operations. To a certain extent, this is a belief, from the belief that unified China, and the corner to the north is missing on China's territory. Ren Di always feels that the place is wrong. Ren Di's worldview, who has been emphasized since childhood, is different from the worldview of this generation of Hai Song elders. Zhao Weiguo understood very well that he knew that Ren Di would complain about the difficulty of the Northeast Battle, insufficient military strength and poor logistics. But he would definitely do his best to solve the Northeast Battle.

In the Elderly Council, Xiao Mingsheng, the elders of the Xiao family, and Beiliang, had their own opinions, and the influence of the poison gas bomb seemed to fade. As Xiao Xuanyun perfectly completed the mission of transporting troops from the Korean Peninsula to the Liaodong region. After successfully blocking the Republican army from the Shanhaiguan area, Hai Song's army quickly took over the Liaoning region. Hai Song's elderly Council shifted the topic of discussion to how to complete the attack on the Republic on other routes.
