"Tong", "Tong", "Tong" Just when Yan Wudao pondered the meaning of the Japanese army's move, more than a dozen mortar shells came from the direction where the Japanese troops left, but the mortar shells that fell to the ground only emitted a trace of yellow smoke and a violent explosion. "Poison gas, it's poison gas, quickly wear gas masks, tell the Burmese to retreat immediately" Yan Wudao hissed, hurriedly snatching the walkie-talkie and ordering Haig and the mercenaries hiding in other underground bunkers to prepare for poison.

This is also thanks to Tang Lei's Qingfeng troops, the Qingfeng troops made two shots to let the mercenaries know the lethality of poison gas, coupled with Zhao Zhi's strong support, the mercenaries who went out to fight all wore gas masks, although it was not the kind of conjoined full-body protection, but it was much safer than Japanese-style gas masks. The new German-style gas mask smelled of rubber, but now was not the time to care, the mercenaries in the pit opened their backpacks and took out the gas masks and put them on their faces.

After putting on the gas mask, Yan Wudao knew that he had made a mistake, the ambush location he chose was just downwind, and the Japanese army could spread the poison gas to the entire ambush position effortlessly along the wind, if it weren't for the mercenaries who carried gas masks according to the order, this ambush would have turned into a one-sided massacre. "Here, the Japanese army is coming" The observation urn with a gas mask slapped Yan Wudao's arm angrily, making gestures to the Japanese army coming up.

More than 300 Japanese soldiers with gas masks were quietly touching over under the cover of poison gas, Yan Wudao flashed a killing intent in the eyes of the gas mask, "Snipers shoot freely, leave this group of Japanese soldiers here for me" The walkie-talkie passed the order that Yan Wudao changed his voice, and the snipers lurking outside began to install silencers on their sniper rifles, and the installation of silencers would affect the accuracy of the snipers, but at a distance of 200 meters, a rookie could also hit those Japanese soldiers.

More than 40 snipers began their hunting feast, and the Japanese wanted to attack with poison gas to take down the steel fortress on the slope, but they didn't know that the snipers were also shooting them with the help of diffused yellow poison gas. The advantages of semi-automatic weapons are evident at this time, the sniper rifle fed by the 5-round magazine is more suitable for snipers to encircle and suppress opponents with a large number of opponents, and all Japanese soldiers who appear in the sniper scope are always knocked to the ground at the first time, even if a Japanese soldier discovers the location of the sniper, they will become the next person to be shot before they give a warning.

The distance of 300 meters became an impassable line of death, and when the Japanese soldiers wearing gas masks touched the position of 300 meters from the steel fortress, the more than 300 people at the time of departure were already less than 100., and if it were not for the dispersion of poison gas that obstructed the snipers' vision, perhaps the number of casualties of this group of Japanese soldiers would have been more. The dispersion of the poison gas also affected the Japanese army's own vision, and the Japanese soldiers who touched the slope suddenly found that there were less than 100 of the more than 300 people left at the time of departure, and most of their companions were missing.

There were less than 100 Japanese soldiers, and Yan Wudao didn't intend to let them continue to live, and after each of the snipers fired two shots, there were still a few lonely figures standing abruptly under the hillside. The Japanese who released the gas bombs did not know that the forward troops they sent had been wiped out, and if they knew that the mercenaries were issued with better gas masks than their Japanese soldiers, perhaps Mutaguchi and Takeuchi would have chosen to take a detour to Lashio.

After the gas bomb was released, more than 300 forward soldiers had been sent out, but there was no movement at all, and the strange opponent and the strange battlefield made a trace of bad thoughts rise in Mutaguchi Ryoya's heart. "Send another squadron up, and if you find that the situation is not right, you will immediately fire a gun or retreat immediately" After thinking about it again, Mutaguchi Ryoya also sent another squadron up to find out, but this time the order was more lenient, allowing the officers leading the team to decide whether to retreat at their own discretion when they found that the situation was not right.

Wearing gas masks, the Japanese soldiers who opened the straggler line cautiously entered the poison gas area, and after walking a short distance, they found the bodies of Japanese soldiers who had been shot one after another. The Japanese gas masks on the corpses reminded them that these people had been ambushed, and the Japanese officers who led the team made a subtle gesture to retreat, and the Japanese troops in a standard triangular formation quietly retreated, and with such low visibility, they could not even find the shadow of the attacker, let alone shoot the attacker.

"The people of Thunder also have gas masks" This is the first thought that rose in Mutaguchi's mind, otherwise, how did they kill all the more than 300 soldiers who entered the gas area in advance, and the people without gas masks are not allowed to fight normally, even if they stand in the gas without doing anything, I am afraid they will not be able to last for a few minutes. The effectiveness of poison gas made Mutaguchi Lian also a little dumbfounded, artillery fire and poison gas were the two invincible killing weapons of the Japanese field troops, but now neither of them seems to be very effective.

The poisonous gas released by the Japanese army slowly dissipated with the strengthening of the wind, and Yan Wudao, who did not dare to be careless, still wore gas masks. All his arrangements were aimed at the Japanese attack, and the Japanese army was holding back, but the steel fortress built by Haig and them could not play its due role. "Contact the surrounding troops, tell them to search the defense line, and be careful of the Japanese army's slippery" Thunder's strength in Lashio is about the same as the Japanese army, but Yan Wudao still has 1,000 mercenaries and 3,000 Burmese guerrillas under his command, if it is really a positional war, it is uncertain who will win and who will lose.

Yan Wudao's side did not move, but the mercenary squads and Burmese guerrillas cruising around the periphery were like sharks smelling blood, and quietly began to assemble on the flanks and rear of the Japanese army, and the Japanese troops who had stopped moving had fallen into the encirclement of Yan Wudao, but they didn't know it yet. "Order the artillery group to scatter at the Japanese troops, and let the scouts on the periphery be responsible for correcting the ruler" The 25-pounder field artillery group has a large number of shells in stock, Yan Wudao is not worried about the consumption of shells at all, he is only concerned about how to kill the cunning Japanese troops on the opposite side.

"Captain, Lashio said that there is no problem, as long as we are responsible for correcting the scale of the shelling, they can hit the heads of the Japanese" The foot soldier pretended to convey the original words of the rear artillery group briskly. Yan Wudao's face had always been gloomy, and the mercenaries hiding in the underground command post didn't even dare to come out, and the young foot soldiers just wanted to adjust some of the atmosphere.

"Those big noses will brag" As soon as Yan Wudao's words fell, the scream of cannonballs cutting through the air sounded in mid-air, and the artillery group had already opened fire. A cloud of smoke rose high in the mirror of the "boom" artillery team, and from a long distance, Yan Wudao could not see the location of the impact point clearly, but those scouts who were arranged on the periphery of the Japanese army could see it, and less than a minute after the first test shot of the shell exploded, there were several whistling voices over Yan Wudao's head and went straight to the Japanese army.

"Boom," "Boom," and "Boom," three explosions sounded in succession in the Japanese formation, and the three craters were connected with the one that had been test-fired, and a Japanese squad belonging to the 55th Division was overturned in half. "Boom" "Boom" The 25-pounder field artillery group seemed to be coping with an errand, and it bombarded the Japanese army's gathering point again and again, and the infantry with two legs threw out the scurrying infantry They couldn't do it, but the mules and horses who were responsible for pulling and transporting artillery ammunition suffered a crime, and the mules and horses of the 18th Division's baggage wing were directly put down by more than a third of the field artillery group's third round of scattering, and the ammunition boxes scattered all over the place now need to be carried by the baggage soldiers themselves.

"Damn, Lao Tzu will see how long you can endure it, and Lao Tzu will force you to stick your head out if you don't get out" Yan Wudao in the underground command post took out his silver wine jug and poured a big sip, the stimulation of the liquor made Yan Wudao's eyes a little bloodshot, and the whole person looked murderous. "Inform the artillery group to continue fighting, don't stop without my order" Listening to the monotonous explosion, the irritability in Yan Wudao's heart gradually dissipated, and the battle was also compared to the patience of the commanders on both sides, saying that whoever shows the flaws first will be defeated, Yan Wudao is now waiting for the Japanese army to make a move, and only when the enemy makes a move can he have a chance to find out their flaws.

"Inform the snipers outside to fire freely, let them all bring enough ammunition, and if they don't beat out the fire of the Japanese army, they won't come back to see me" The shelling alone is not enough, Yan Wudao plans to add another fire. The sniper team that only shot once is the best choice, so that those Japanese soldiers can see their companions die in front of them, and they can't find anyone to shoot, Yan Wudao believes that this will definitely force out the anger of the Japanese army, and he wants to force the Japanese army to come to him for a decisive battle.

"Report, the left flank was attacked, more than half of Kono's squad was killed or wounded, and Kono's second lieutenant was broken"

"Report, the right flank was attacked, more than half of the casualties of the Far Mountain Squad, and the Second Lieutenant of the Far Mountains was broken"

"Report, the rear guard unit was attacked, and the Takekami Shozo Yu of the baggage wing was broken"

In just half an hour, there were more than a dozen heralds who came to report the situation of the battle, and the two wings of the Japanese army and the rear guard units were attacked one after another, and when asked about the officers and soldiers present, they all said that the location of the attackers had not been found, and no one even heard the gunshots.

"Lao Tzu just wants to toss them, don't you want to stretch out your head? Lao Tzu hit them until they stuck out their heads and let Lao Tzu cut them, "The chaos in the Japanese front has already been passed to Yan Wudao by the peripheral scouts with walkie-talkies, and Yan Wudao, who is in a mouthful of wine, is not in a hurry now, it should be the Japanese army who should be in a hurry."
