The most amazing thing is the extensive pipe system made of bamboo, which can be described as wonderful.

Liu Guodong organized the workers of the forest farm to open up the bamboo joints of the big bamboo and bring mountain spring water from the mountain. The water is then brought to each house through bamboo pipes that extend in all directions. In the middle of the camp, there is also a large shared water tank made of coarse bamboo, and when you open the plug on the pipe, there is a clear mountain spring water gushing out, which is very convenient.

After lunch, Lin Zhumin drilled out of the hole first, and after confirming that it was safe, the rest of the people came out one after another.

Outside the cave are dense jungles, but the trees are not thick, and the main body of the forest is a secondary rainforest. Nature is the harshest, only a mountain away, and you can't see the towering red forests, red acid branches, and all kinds of thick sandalwood, elm, pine forest, and binmu that are more than 100 or hundreds of years old on the Lancang side.

"Annam's mahogany processing industry is exported to the whole world, and its own mahogany has been cut down, and it was seriously damaged by the M army defoliant a few years ago, and the current vegetation of Annam is mainly secondary rainforest. The high-quality primeval jungle timber resources needed by the wood processing industry mainly rely on the Khmer and Lancang countries. Liu Guodong said.

Lin Zhu covered the entrance to the cave with plants and vines, and everyone took cover alternately, diving into the depths of central Annam.

This is the first time that Yu Songyuan has penetrated deep into the hinterland of Annam, close to the border mountains, where the mountains are continuous and the trees cover the earth. Seven or eight kilometers east along the col, at the edge of the mountain, plains, villages, and dirt roads loom ahead. Yu Songyuan signaled to hide, while he and Lin Tao climbed to the two big trees and took out binoculars to observe carefully.

It is located in the middle of the Chang Son mountain range, with an altitude of more than 1,000 meters to 2,000 meters. Through the telescope, the sea, the coastline and the gray outline of a city are already faintly visible. This small city must be the coastal city of Donghai. More than 100 kilometers south along Highway 1 from Donghai is Donghe City. In Yu Songyuan's heart, the outline of a plan had slowly formed.

The terrain of Annam is long and narrow, with Cochin in the south and Anbei in the north, and the area is relatively broad. If the Anbei region is compared to the head, the cochin is compared to the lower limbs. Then, in the central part of Annam, that is, around the 17th parallel, such as Quang Binh Province, Quang Tri Province and other areas, it is the long, narrow and thin waist, which is the weakest part.

Lower the telescope, and the village will be clear at a glance, and the scene will be clear, as if it were in front of you.

Under the lens is a serene, dilapidated, and impoverished mountain village, with dozens of families. A piece of tall thatched huts made of bamboo, and a piece of broken grass sheds. There is a pond in the middle of the village with lotus flowers. At the edge of the pond, a large group of bare-bottomed children were playing and playing. In the fields next to the village, several buffaloes and cattle are grazing with their heads down, and villagers wearing hats and bare feet are busy in the fields......

Yu Songyuan was puzzled, why is such a backward and impoverished country so belligerent and frequently challenges its strong neighbors in the north? What kind of nation is this, what kind of country is this?

There is only one explanation, the victory in the Vietnam War, which completely carried away their heads. If God wants to destroy it, he must first make it mad, and that's right. Perhaps the deeper reason is that Annan has a constant cultural and geographical connection with China, and in the face of this bordering power, Annan has always been wary, and this big country is also the shackle that Annan wants to get rid of the most.

Yu Songyuan's mind flashed through the country's two wars, 1789 and 1979.

In 1776, the three brothers, Nguyen Yue, Nguyen Hue and Nguyen Lu, raised an army to overthrow the Le Zhao clique attached to the Qing Dynasty of China. In order to reflect the authority of the suzerain, in 1788, the Qianlong Emperor of the Qing Dynasty sent the general Sun Shiyi to lead a large army into Annam and fought until Thang Long. In the Spring Festival of 1789, Nguyen Hue led his troops north to fight, and Sun Shiyi was defeated by the enemy.

The border war of 1979 ended very differently. Annam was defeated, the capital was shaken, and the panic of the death of the country completely enveloped this long and narrow country. The dream of being "the third military power in the world" and "the Federation of Indochina" was completely shattered, and although the Chinese army quickly withdrew from the country and the war ended quickly, Annam's economic and social development has been set back by more than 20 years.

The war broke Annan's blood, but they did not learn their lesson, and still implemented the national policy of long-distance friendship and close attack, which is incomprehensible......

At this moment, a train appears in the camera, spewing thick smoke, along the coastline, from south to north. Looking at the land under the camera, Yu Songyuan's heart paused, and suddenly he had a complete idea. From the Cologne base, it is possible to stealthily attack any target in its depth, and it is possible to pick up a freight train, move from the attack site to the cave sea without noticing, and then it only takes two or three hours to reach the border on foot.

"Ghost attention, someone on the hill to the right of the village is heading here!" Lin Tao warned in the headset.

Yu Songyuan moved to the back of the village, in the telescope, the green mountains are like daisies, and there are four "hunters" in the mountain forest, who are following the slope of the mountain, showing their figures from time to time in the secondary forest. Their direction is precisely the border.

Judging from the way he walked and the weapons they were carrying, Yu Songyuan quickly judged that this was the special team of the Provincial Military District of Quang Binh Province in Annam. In each of the local military districts, Annan has a special team, and they come to patrol the border.

"Attention Assassins, they're here to patrol the border, and the squad is retreating!"

Yu Songyuan and Lin Tao slid down the tree, and they began to return the same way, and the broken Lin Zhumin helped up the trampled vegetation from time to time. When I returned to the camp, it was already two or three o'clock in the evening.

This reconnaissance gave Yu Songyuan an intuitive feeling of the terrain in the hinterland of Annan, and a complete idea of attack had begun to sprout in his heart. With a brother squad of only four people, the only way to inflict a huge psychological shock on the Annan army, which has a total of millions of people, and to covertly attack its core military nodes to support the war, is the only way.

After washing up and falling asleep, Lin Tao had already fallen asleep. Yu Songyuan couldn't calm down for a long time in the howling sound of the wind blowing through the forest outside. He gently put on his clothes and got out of bed, quietly entered the outer war room, lit a candle, and looked at the map of Annan on the wall, lost in thought.

The elite of the Annam army is divided into two major military groups, the north and the south, nearly 300,000 elite field troops stationed in Khmer, and 300,000 main corps defending the northern border. The current basic situation is to gradually withdraw part of the troops from the southern bloc stationed in Khmer to support the war on the northern border.

For the Annan army, which has been mobilized throughout the country, the most critical thing at present is the "grain and grass" of the modern army - oil, ammunition and equipment! The most effective way to play in the brother squad is to hit its "grain road"! He came to the sand table with a candle again, put the candle on the candlestick, lit a cigarette, and stared at Donghe for a long time and couldn't bear to leave!

As a commander, he knew all too well what his decision would mean. As the captain, he not only has to lead the team to complete seemingly impossible tasks, but he also has to lead the team to return and return to the building! When he stared at the East River on the sand table, frames flashed in his mind:

The elite army of Annam, which had withdrawn from the Khmer battlefield, suddenly suffered a fatal blow at the Dong River, destroying all the "grain and grass," the army was in chaos, and the strategic plan of the two major groups in the north and south to coordinate with each other was completely bankrupt......

Suddenly, he felt his blood boiling, and he couldn't help humming "Holy War", the suppressive, heroic, and unrestrained melody, like a stream of iron, echoed in the war room......

Suddenly, he was awakened by the sound of Suosuo. Looking back, it turned out that Mei Xue had been sitting on a stool not far away, it was very cold in the second half of the night in the camp, and Vivien was putting on a thick pajama for her. "Girl, it's almost dawn, why don't you sleep?"

"I've got to watch you and prevent you from harming yourself again!" Mei Xue's teeth chattered and trembled.

Yu Songyuan was very moved, he walked over and hugged Mei Xue in his arms, and the little maid Vivien also hugged the princess's arm tightly and put her head on Mei Xue's back......

In the following time, the team carried out primeval jungle combat training within the primeval jungle of dozens of kilometers around the camp, and took the opportunity to thoroughly inspect the primeval jungle of the Cologne base.

They also made a special trip to the red sour branch felling team to cut down the trees for a few days. Of course, the main purpose of the special trip to the logging team is to grasp the overall situation of the forest farm and assess the safety situation. But this trip also has a bit of a smell of burning, and the team and the captain of the logging team, Long Lin, who is also the younger brother of the big leader Long Ji, have a grudge. He also established a "friendship" with Li Hong, the "consultant" of the 678 Corps stationed in the forest farm of Annan.

"Captain Yu, you have to go to the logging team, take Mei Xue and the others with you, a few little princesses are suffocated. By the way, let them get some jungle professional training! Before leaving, Long Ji and Lao Zhou interceded together, Long Ji didn't dare to speak, and Lao Zhou mustered up the courage to say.

"Cut, we're training, you think we're playing? Besides, there are many dangers in the forest, they are all delicate women of the elder's family, and they can endure this! Lin Tao took the lead in opposition, and everyone in the team didn't want to go into the mountain with "trouble". Liu Guodong and Lin Zhumin couldn't wait to take Su Gong and Mei in their mouths, and they were even more reluctant to let them suffer.

"Captain Lin, you can't say that. Yingya is their eldest sister, and every time she goes to the forest farm, she has to go to the logging site to comfort the workers. The Long Dai tribe has less than 10,000 people in Vientis, and we have tens of thousands of people living in the border mountains, and we are still a mountain people......" Long Ji looked at a few sisters-in-law, and began to confront Lin Tao.

Lin Tao was about to refute, but Yu Songyuan waved his hand, "Don't fight, from today onwards, let them participate in training!" ”

Mei Xue and the others cheered, hurriedly ran to the equipment warehouse, put on the jungle combat uniform of the M Army, and carried a backpack on their backs.

It turned out that they had planned it a long time ago. The four members of the team had to check their equipment separately, one M16A1, one Colt M1911, one dagger, sleeping bags, ropes, medicines, food, drinking water, ammunition, etc., a complete set.
