The offensive and defensive forces in human beings are generally three to one or even five to one, and after the appearance of hot weapons, they are reduced, but they must be at least two to one to move.

However, the current situation is not a contest between people, two completely different forms of biological civilization, axillary people have an absolute advantage in physiological functions and physical fitness, and their weapons are not inferior.

In this case, they dared to launch a full-line positional battle with half the strength of the frontal human race, causing twice as many casualties as the human race. And for humans to attack them, the attacking force needs to be at least five times their strength, and pay three times as many casualties as they can break through the defense. At this rate, the fǎn gōng is now launched, and the casualties are still very large.

In addition, the Xian army has lost the opportunity to use chlorine gas to preemptively strike, and the armpit artillery fire covers all important targets and possible positions where artillery positions can be established, and the Xian army has no time for deployment or counterattack, and at the same time, it also has to risk the spread of chlorine bombs, which obviously outweighs the losses.

As for the empty boat, the load is limited after all, and it takes a whole day to take off and land and load it back and forth, which is too inefficient and inadequate.

Bai Liyan thought about it again and again, planning to observe for another day, and at the same time ordered the cannon brigade under the command of Zhou Kong to rush to Cuicheng with chlorine bombs and gas masks to carry out poison gas warfare against the armpit army north of Cuicheng.

Although Jinye was more important than Cuicheng and Tianyungang, Jinye Port was lost, and the large hills west of the port fell into the hands of the armpits, which was not conducive to future fǎn gōng battles.

The next day, all reconnaissance indicated that the enemy in front of him had quietly withdrawn his troops in the night, and that the frontal artillery attack and offensive posture were only an illusion.

Unlike human beings who need light sources for night activities, axillary people benefit from night vision organs, and night marches can do without lights, even if they are driving ships, they need to set up lights, and they can also dock in low light conditions, and the Xian army can't see them retreating at night.

During the day, their military tents did not decrease, only a small number of personnel were sent to continue to pretend to be active, and at the same time, a small number of ironclad ships with a higher volume ratio were dispatched, which could carry two or three thousand people at a time, and they could take away thousands of people and a large amount of equipment with only one round trip every day, and they could indeed deceive humans in the first few days.

On the fifth day of the shelling, the artillery fire had weakened significantly, and it was clear that some of the howitzers had been removed last night.

At this time, the situation was clear, Bai Liyan still did not plan to counterattack, he believed that if the coalition forces counterattacked, whether they succeeded or not, they would pay heavy casualties. Since they can dig holes in the ground and bury zhà yào, they will naturally prepare zhà yào in their own trenches, and if the Xian army attacks rashly, they will fall into a trap and die without a place to be buried.

When the shelling reached the seventh day, even fools should see that this was a retreat, and Bailiyan decided to start a counterattack, but he did not intend to send troops to attack on all fronts.

Still using 121 rocket artillery to ride the pickup truck, taking advantage of the gap between the artillery, taking turns to cover the enemy in front of him and the trenches, no matter what the effect is, Bailiyan no longer wants to kill more people.

And it turned out that his previous judgment was accurate, and the two waves of salvo detonated part of the Xiāo ānzhà yào piled up in the enemy trench.

These zhà yào were supposed to be filled in at the feet of the coalition forces and Liang County, and then send tens of thousands of people to the western sky, but when it came to Cross, he planned to give the coalition forces a salute, but the result was not successful, but the explosion killed and wounded himself five or six hundred people, this loss is not as many as the casualties of the coalition forces caused by the shelling in the past seven days.

Looking at the flames and dust rising from a distance, the generals were inevitably frightened, and Mo Yunfeng, who had been clamoring for fǎn gōng, shouted that he was lucky.

"It's so hanging, if you attack, I really don't know if you will kill my brother."

At this time, Bai Liyan answered

"In the future, you must remember that the treachery of the armpit is unprecedented. But when you fight with them, you need to think about the worst, don't think that you are smart, but in fact they are more treacherous. ”

After several encounters, Bailiyan summed up an experience, the thinking logic and physiological functions of axillary people determine that their code of conduct and bottom line are lower than those of humans.

Obviously they want to get out of the way, but they bury themselves under themselves, and they are humans, which is not very consistent with human logic, since they want to leave alive, and they have a great degree of certainty, but they still have to take risks, which is obviously due to their strong physiological self-healing function.

Therefore, where there are taboos in human thinking, they often have no taboos, and the bottom line of human morality is precisely the upper limit of their logic.

In addition to scientific and technological reasons, the differences and shackles of thinking are also important reasons for the failure of the white people in the western continent of the northern hemisphere.

The bào zhà lasted for two days, and under the gaze of the coalition forces, the armpit people boldly withdrew the troops in front of the defense line, and it was the armpit howitzer that puzzled Bailiyan from beginning to end.

Due to the difference in structure and design concept, the weight of the armpit howitzer is quite heavy, and Bailiyan, who had never understood how to get ashore, but this time it really opened his eyes.

It turned out that they were pushing the cannon directly onto a huge log raft pre-positioned in the mud of the Vortex Ford with barrels under the raft. After the artillery fire goes up, it is firmly tied with iron wire, and at the same time the level of the gun body is restored, and a just right center of gravity is obtained, and then the iron chain is tied to the artillery, and it is directly worn and pulled away with iron armor cans, and several guns can be pulled at a time.

The artillery sat on rafts and barrels and dragged directly out of the swamp, and after entering the water, a third of the artillery was too heavy to sink into the sea, but it did not sink. The guns were chained to the artillery, and the hinged pulley system attached to the ironclad canned ship was used to stir the guns onto the deck through the power structure driven by the steam engine.

If you want to go ashore, you do the same, but you have to rely on orcs or giants to pull you ashore.

Moreover, from a technical point of view, it is not difficult to find that at the beginning of the design of the howitzer, the space for barbaric operation was fully considered, so the structure of the gun was relatively compact and the leather was resistant to tossing.

Such a crude operation method also really shocked the well-informed Bailiyan, and it was obvious that although this kind of measure was unsafe and lacked basic norms, it was undeniable that many technical obstacles were solved.

In the absence of a complete port, the successful transfer of heavy artillery from the tidal flats to the inland is so fast, efficient, and rough that perhaps only the armpit dwarves can do it. The so-called no bottom line, I'm afraid the same is true.

The first battle of Liangxian came to an end, but Bai Liyan did not forget to let the empty boat chase to the sea to continue harassing, and as a result, he also achieved some results, severely damaging a 30,000-stone sailing ship, and the casualties were unknown, which made Oka, Cross, Kusa and other senior generals crazy.

The battle of Liangxian County of the Xianjun army finally ended temporarily with the withdrawal of Oka troops, but no one felt that this battle was won, and everyone felt that they had suffered a loss.

Needless to say, from May onwards, including the Xian army, the casualties were less than 170,000, more than four times that of Cross.

But Cross still feels that he suffered heavy casualties in this battle, and there are probably two reasons for this.

First, half of the casualties occurred after the arrival of the Xian army, and he had been fighting smoothly until then. Second, if you don't consider your own population base and strategic force conversion ratio, the cost of dying an axillary person is almost four to five times that of human beings, and if the casualties are less than five times, they will suffer in terms of reproductive speed.

Taking a step back, before going south to attack the southern hemisphere, the front army led by Cross had attacked the white continent for nearly 30 years, and the total casualties did not exceed 100,000.

However, it was a foregone conclusion, the dead could not be resurrected, and after the withdrawal of troops on land, Oka still left a detachment fleet to continue to entrench in the sea north of Whirlpool Beach, and the main fleet loaded the headquarters of Cross and rushed to Tianyun and Jinye for reinforcements.

At the same time, Bai Liyan pushed the battle line to the Whirlpool to clean up and search the battlefield between Liangxian and Whirlpool, especially the underground zhà yào needed to be further cleaned up, and at the same time he personally led people to inspect the floating docks and earthwork operations left behind in the Whirlpool Beach, trying to gain some experience and technology.

The Whirlpool itself is a tidal wetland, so it is impossible to carry out a large-scale landing here, especially with heavy equipment and supplies, which is not possible even with modern technology.

Because it was impossible, neither the Liang army nor the Yuke were on guard here, but no one expected that the armpits would use liquid nitrogen to freeze the tidal flats and wetlands, and then go ashore to establish a beachhead, and build channels and floating docks with timber and pontoons for their vanguard troops to go ashore, and finally fill in some tidal flats during the implementation of earthworks.

Such a bold plan is hardly a tactic that humans can imagine to apply, because there are too many realistic technical conditions, which restricts the use of liquid nitrogen as a warhead, and Bailiyan is eager to know what technical means are used by the armpit to achieve the goal.

The clearing of the battlefield continued until 657, when the situation underground was complicated, and more manpower had to be mobilized for earth-digging due to the complexity of the underground situation, and the poison gas attack on the enemy who landed north of Emerald City was ineffective.

One is the wind direction and geographical problems, Tianyungang belongs to Cuicheng, and Cuicheng is more than 100 miles inland, the west is hilly landform, and the wind direction has a great influence, and the other is that Bailiyan found that they were roasting charcoal from the enemy position left in Liang County.

From this, it can be concluded that they will not be able to produce anti-poison equipment suitable for armpit people in the short term, so they have to retreat to the next best thing, using simple masks made of charcoal pellets to filter mouth and nose gases and prevent chlorine from entering the body.

Activated charcoal is a charcoal substance that has been pickled and reactivated, while charcoal has not been reactivated by acidification, so the adsorption force of activated carbon on gas is stronger, while charcoal is weak.

However, the molecular diameter of most toxic gases is larger than that of charcoal, so it cannot pass through the solid tissue gap composed of charcoal particles and powder, and charcoal has a certain weak adsorption force, which can indeed play the role of filtering chlorine air, but it cannot avoid the contact between chlorine gas and the mucosal liquid exposed to the eyes, resulting in corrosion damage caused by hypochlorous acid.
