No one would be afraid of the large-scale mobilization of troops in South Vietnam, and they would follow the movement of North Vietnam, but the new defoliant had never been seen before, and it immediately suffered a loss at the first contact.

It should also be said that the caves dug by the North Vietnamese made a great contribution, and after the initial poisoning, the North Vietnamese guerrillas hid underground, and the spread of the poison was reduced in a large area.

But this dodge is in response to Dinh Yan's words, the war is about to burn to Hanoi City!

Almost one-third of the country's land is covered by tropical evergreen and subtropical deciduous forests, which justify the use of defoliants, an industrially synthesized venom that kills plants or causes them to lose their leaves overnight.

Defoliants are mainly "Agent Orange" and contain large amounts of toxic chemicals, including a highly toxic substance dioxin (TCDD) with a long-lasting effect.

Agent Orange is a highly effective herbicide named "Agent Orange" because of the orange color of the logo stripe on its container.

The US military sprayed forests, jungles, and other vegetation that were judged to be hiding places for Communist Party fighters at low altitudes and at slow speeds, causing trees and other plants to lose their leaves.

It contains a chemical poison called 2,4,5-T, a compound called dioxin, commonly known as dioxin.

The venom-spraying operation, which the U.S. military named Operation Ranch, used planes to spray 76 million liters of defoliant herbicide into the jungle of Vietnam, removing trees that shaded the sky.

The U.S. military has also used the herbicide to destroy rice and other crops in Vietnam, spraying 10 percent of South Vietnam's total area, 34 percent of which has been sprayed more than once.

If the U.S. military wants to give full play to its artillery superiority, it must first remove the obstacles on the landing point of the artillery shells, and this plan has actually been planned for a long time, and the assassination of Ngo Dinh Diem just catalyzed this operation, and when it comes to the jungles of Vietnam, the U.S. military is deeply hated, and the Viet Cong guerrillas haunt the dense jungles, coming and going without a trace, striking east and west, and making the U.S. troops dizzy.

The Vietnamese guerrillas also took advantage of the cover of the dense forests in the Truong Son area to open up the "Ho Chi Minh Trail" connecting the north and the south, ensuring the smooth transportation of supplies. In order to change the passive situation and cut off the supply of the Viet Cong guerrillas, the U.S. military decided to first try to remove the visual barrier and completely expose the Viet Cong army to the fire of the U.S. military.

Their plan proved to be very successful, and of course this behavior was also vicious, and it is important to know that in the dense jungle there are not only the Viet Cong, but also the 38th Army and other Chinese troops, and naturally there are ordinary people hiding in the jungle.

The chemical properties of defoliant are very stable, it takes 9 years to reduce 50% naturally in the environment, and it takes 14 years to excrete all after it enters the human body.

This ranch operation was the second chemical war openly waged by the U.S. military in Vietnam since the Korean battlefield, which naturally aroused the anger of the people and gods!

When Xingtian returned, it was just in time for the U.S. military to start the ranch operation, and the North Vietnamese, who learned the news, hurriedly told the Chinese supreme person in charge of the news, and then ordered the order to start descending to all corps companies, all of which entered the tunnels to avoid chemical agents!

Fortunately, before the returning Xingtian had time to handle the training and receive the bounty, he took the new and old Stinger team members and followed the North Vietnamese guerrillas into a half-man-high hole!

This large-scale chemical drop directly affected all the North Vietnamese combatants, and the 38th Army was no exception, and those soldiers who had just received ammunition and were ready to fight were also blinded for a while when they received the order, and then in Li Yunlong's reprimand, the large army abandoned the fortifications exposed outside the hill and hid back in their own air-raid shelters, and some of them also went to the tunnels dug by the North Vietnamese.

After Xingtian drilled into the tunnels of North Vietnam, he was first choked by this small environment, and then finally the space became wider after reaching the depths of the cave, and generally the large space dug out of the underground depths was used as a headquarters or to store important materials!

Now a large number of Chinese and Vietnamese soldiers suddenly poured in, this wide underground space is not enough, the situation happened too suddenly, the North Vietnamese side did not expect the US military to do such a desperate thing, large-scale use of defoliants, and now the headquarters of the cave is busy expanding, otherwise so many people just don't have enough air!

Xingtian brought their team members together with their own team, and Xingtian was really tired after a few days of hard work, after he gathered the people, he gave a little instructions to lean against the earthen wall and sleep, the sky fell and the ground continued, it can be predicted that after the poison was sprayed, it was the moment when the South Vietnamese army attacked in a big way, how to fight behind without enough spirit, Xingtian didn't think that Li Yunlong would let him go.

Alas, this Master Li~

With his own complaints, Xingtian fell asleep, and in such a crowded and chaotic environment, Xingtian and Chu Jian and the other three also slept, and the surrounding soldiers could also see that these three people were really tired.

When Xingtian woke up, the hole was already much wider, and Gao Baoguo, who was wounded in the shoulder, told Xingtian that the U.S. military had dropped defoliants, and when Xingtian was sleeping, six hours had passed!

In the past six hours, the US military began to drop a large amount of venom from the coast to the jungle area infested by the Viet Cong, as if the release had been completed, and no US military planes had ever appeared, but now they could not leave the hole, the venom outside was volatilizing, and it was necessary to go out at this time to be poisoned!

Xingtian, who woke up, pinched his brows and said: "It doesn't matter, the toxicity of defoliant is not very strong, and inhaling a small amount will not be fatal, but it can't be invaded by poisonous gas for a long time, otherwise it will be troublesome!" ”

Gao Baoguo asked: "What kind of trouble law?" ”

Xing Tian sat upright and took a sip of water and said: "If you come into contact with a large amount of defoliant, although you may not necessarily die, you are 100% sure that it will change your fertility and genetics, so that the children you will have in the future will either lack arms and legs, or will be born idiots!" ”

Gao Baoguo took a breath of cold air and scolded: "My grass, so poisonous!" Then why don't we hurry up and get some anti-chemical equipment to wear? ”

Xing Tian waved his hand and said: "Don't worry, let's see what those North Vietnamese people will decide, if nothing happens this time, it will be a close-range encounter, and from this cave, there will definitely be mountains and fields outside the US-Vietnamese coalition army!" ”

This is Vietnam, naturally the Vietnamese themselves want to sing the leading role, it doesn't matter if they come forward or not, Xingtian still doesn't believe it, if he doesn't fight, someone dares to order him?

There is no Vietnamese here who can order him, and Ho Chi Minh is here to make it, he does not belong to any army now!
