From this picture, it can be seen that the cloud is the size of several football fields. It was built on the top of a mountain that stood abruptly detached, piercing the sky like a sword, hidden in the mist.

This mountain is located in the mountains south of the county seat, about fifteen or sixteen kilometers away from the county seat. The relative elevation of the mountain is about 1,500 meters high, and it is surrounded by steep cliffs and no grass on the walls. Only Area D, on the north side of Yunyao, has a few kilometers of iron ropeway, which is connected to the outside world from top to bottom. There is a spring water at the top of the mountain, and the supplies needed on the mountain, and the entry and exit of personnel, are all lifted back and forth through the iron ropeway.

At the other end of the ropeway, a base was built on the edge of a cliff with an infantry battalion.

Inside the cloud cave is a medieval-style European castle building. It is built on a hill, with a castle in a circle, the walls of the building are level with the cliff, and the four corners are built with Gothic bell towers. In the middle of the building is a large square. The building is divided into four ABCD districts in a clockwise direction, with Area A to the east and BC to the south and west to be the headquarters of the 821 Special Agent Group, and Area D to the north to be the garrison of the guard company.

On the back of the map, there is dense Chinese cursive small characters, although the handwriting is very sloppy, but the dragon and phoenix dance, very beautiful. The text reads:

"In the middle of the night after the 28th of December, I ordered you to enter the mountains south of the county seat. According to the direction shown in the map, before January 3, it is necessary to enter the mountain stream on the north side of the cliff base of the Yunyi stronghold, and find the location of Yunyi's D area to hide and standby. At ten o'clock in the evening of the 29th, there will be a bamboo basket at the bottom of the stream in the D area of Yunyi, and you should quickly board the bamboo basket. At 10:15 a.m., the bamboo basket will be hoisted to the ropeway station in Area D. ”

"Then, you move from Area D along the small platform outside the building to Area B. From 10:30 a.m., a rope will be lowered from the safe house, so please climb the rope immediately to climb the cloud. I will provide you with a map of the internal defenses, and after the attack, please rappel directly from Area D or parachute down to the bottom of the stream. There will be someone waiting for you in the mountain stream and picking you up, and then rushing to the Mengtianfu military airport! ”

Yu Songyuan was shocked in his heart, there was a huge loophole in the plan. This is a towering peak at an altitude of 1,500 meters above sea level, the top of a high mountain, with extremely fast winds and rapid airflow. The mountain peaks are undulating, the jungle is dense, and the situation is unfamiliar, and it is difficult to escape safely by abseiling or parachuting at night!

But on the surface, he still casually handed the map and the attack plan to everyone and circulated it.

Everyone was also stunned for a moment, since they left the training camp, they have experienced a bloody battle of life and death, and they have survived desperate situations again and again. They all knew that another extremely serious challenge was in front of them.

Seeing that the atmosphere was a little dull, Lin Tao glanced at his comrades-in-arms and knew that it was time for him, the deputy captain, to speak.

"The plan seems to be very complete, but the abseiling and parachute 1,500 meters into the bottom of the stream is not very reliable. Fifteen hundred meters, there are many mountains below, and the bottom is full of valleys and jungles, and there is no alternate landing field. It is unknown what the air currents are and how strong the wind disturbs. I need to find another way to escape, and I think I can find a way. Now, we are unfamiliar with the situation and can only focus on how to enter and attack! ”

Liu Guodong and Lin Zhumin also stared at the drawings and pondered, and they both said, "I agree with the second child's opinion!" ”

Life and death have been in the past few years, and Yu Songyuan knows what his comrades-in-arms are thinking. There is never a perfect "plan" for cruel secret warfare. Adapting to situations and surviving in a desperate situation is commonplace, and it is also the basic survival skill of "ghosts". In many cases, the actual situation on the battlefield is completely different from what was detected before the war. Completing the mission is the first priority, but how to escape secretly after the mission is completed is always the most important issue.

Because, one of the dogmas of the sharp knife is to never do "one-shot trading!" ”

"Abseiling and parachuting are too risky to consider for the time being. Once we had entered the cloud and completed the attack, we slipped away quietly through the ropeway! The most important thing is that the attack must be done stealthily! ”

Yu Songyuan seemed to be categorical, but in fact, he didn't have any bottom in his heart. In order to retreat by ropeway, it is necessary to take control of the lower ropeway station located at the base at the bottom of the mountain. But there is a garrison battalion and a company of the 821st Regiment in Yunyi, and no one is sure that they will complete the attack without firing a single shot. And as long as the intent of the attack is exposed, the consequences will be unimaginable, so what is the escape?

But he said so, and others had to stop discussing the issue.

The witch became very quiet, and she curled up like a kitten, with her eyes closed and not saying a word. Zhou Yingzi hugged her son and sat quietly beside her.

"821 was originally a marine special forces regiment, and like the 126th Marine Special Agent Brigade, it was a special forces unit composed of various special forces detachments in the late Vietnam War. Why did they choose the deep mountains and old forests as their base? Lin Tao was silent for a while, and asked Zhou Tieli and Boss Chen.

Zhou Tieli introduced the relevant situation of the base.

The Yunyi base was built by the French Army during the French colonial period, and the Mengtianfu base is the two poles of a defense system. At that time, the county seat was still a small village, with no road connecting with the outside world, and all supplies had to be airdropped.

At that time, the purpose of the French army to build this base was to build a permanent and impossible permanent base, and to lay a nail in the north and south of Annam forever. Even if the Mengtianfu base was captured by the Annan army, under the condition that Annan did not have an air force at that time, it was simply a fool's dream to conquer the Yunyi base.

During the Vietnam War, the people of Country M bombed and bombed the north and south of Annam indiscriminately, but this base was unscathed. It was reopened after the Border War of '79. In recent border conflicts, the main combat targets of 821 have become reconnaissance brigades of the Chinese Army. Since then, 821 has put its nest here.

"Judging from the map, if it is not through air strikes, it is indeed impregnable. It also makes sense that Annan hid their hardcore elite here. After all, it is impossible for us to attack it with bombers or missiles. After Zhou Tieli finished the introduction, Liu Guodong leaned on the picture and said.

Yu Songyuan made up his mind, he looked at Zheng Shuwen, she just nodded trustingly. Yu Songyuan glanced at the diving watch on his wrist, "Let's rest for a while, it's half past ten, and we will set off on time at twelve o'clock at night, and Lao Tzu will set foot on this cloud nest!" ”

Lin Zhumin and Liu Guodong wanted to check the equipment, but they saw that Zhou's sister-in-law, Zhou Yingzi, and the two boatmen had already prepared them for them.

At twelve o'clock in the night, the four team members said goodbye to Zhou Tieli, Chen Boss and Chen Yingzi, etc., everyone's hands were tightly clasped together, and a thousand words were all in silence. Zhou Tieli ferried them to the other side of the Tuojiang River in a small boat, and they quickly disappeared into the night.

On the sky ahead, the peaks are standing tall, and the shadows are full of shadows.

Lin Zhumin opened the way in front, Liu Guodong broke off in the back, and the team quickly interspersed with the mountains in the south of the county seat. It is still five or six kilometers away from the county seat, and the mountains are continuous, all of which are dense tropical rainforests, and many places are difficult to walk.

From Boss Chen's house on the bank of the Tuojiang River to the location of the Yunyi base, the straight-line distance was only seven or eight kilometers, and the curved distance was only more than ten kilometers, but they walked for several hours. What's even more hateful is that less than half an hour after departure, a gust of wind rose, the jungle rattled, and then, the light rain fell non-stop.

The jungle is slippery and difficult to walk, and if you are not careful, you will fall down the mountain.

"What the is this called a bear place, it's raining in winter......" Lin Tao fell at a cliff. Fortunately, Yu Songyuan grabbed it and didn't slide off the cliff.

The witch and Yu Songyuan walked in the middle, walking with difficulty along the passage opened up by Lin Zhumin and Lin Tao alternately. She didn't say a word, stumbling, her hands through the raincoat, clutching Yu Songyuan's backpack tightly. In less than an hour, she fell a few times. The witch who has been trained rigorously is a little out of standard, and Yu Songyuan seems to see that she is a little absent-minded.

Just in case, he had to take out the rope to make a safety belt, "click" and "click" twice, and the drill ring was buckled to the belts of the two people. Climbing steep mountains, severing dense, blocking vegetation, traversing moss-covered slippery ground, and traversing untouched pristine rainforest at night can be both difficult and treacherous.

More dangerous are a variety of large predators, which from time to time trail behind them or pass around the perimeter. A small pack of wolves, about a dozen of them, launched an attack on defender Liu Guodong. The wolf's scream made the witch feel uneasy, and she wanted to return for help, but was stopped by Yu Songyuan.

The wolves kept teasing, but Liu Guodong was silent and didn't pay any attention to it. When the wolves attacked, he used a crossbow and a diving knife together, and killed four or five jungle wolves one after another, and the wolves retreated in a hurry, and the rest of the animals did not dare to attack them again.

Before dawn, they finally went through hardships and dangers, and unknowingly came to the mountain stream below the Yunyi base.

At this time, in the darkest hour before dawn, this place is located just below the Cloud Cave Base Area C. Liu Guodong found a relatively hidden small cave in the bamboo forest opposite the mountain stream, checked it with a flashlight, and there was no major threat, so several people hid in the mountain stream.

The biggest threat here is not animals, not cold rain, but dirty. The entire mountain stream, to the surrounding jungle of several square kilometers, is littered with all kinds of garbage. "It's disgusting!" The witch muttered quietly.

When building the base, the French made full use of the tradition of Europeans to dispose of sewage from the Middle Ages to the modern era. For nearly 100 years, the bottom of the mountain has been the sewage tank of the Yunyi base, and the feces and garbage are directly discharged to the bottom of the mountain.

During the rainy season, flash floods wash away batches of garbage. But once the dry season comes, garbage and manure will be everywhere. Even though it's winter and the nights are relatively cold, the smell is still disgusting.

There is a cold swishing sensation in the small cave, but the ground is drier. What is particularly puzzling is that it is much cleaner than in the mountain stream outside. Liu Guodong gathered a bundle of firewood and lit a bonfire. Everyone was tired, poured water from the bamboo tube, cleaned it briefly, and then Lin Tao stood guard, and the rest of the people sat around the bonfire to recover their strength.

After dawn, Lin Zhumin and Liu Guodong sneaked out of the cave and carefully reconnoitred the surrounding environment with the help of the cover of the dense bamboo forest. The black marks on the rocks indicate that if it were the rainy season, it would be completely flooded. The garbage heap at the bottom of the mountain stream is covered with all kinds of debris that has fallen from the base above, as well as dozens of human skeletons.
