Yunnan Province is the province with the highest forest land coverage rate in China at the beginning of the 21st century. With the continuous development of science and technology, vegetation has been continuously destroyed, and it was not until after human beings successfully colonized the moon and Mars and other planets that the countries of the earth reorganized the ecological environment on a large scale, and the forest area of Yunnan Province reached its peak again.

After the era of the Great Destruction, the vast vegetation of Yunnan Province became a paradise for exotic beasts.

Taking the original Xishuangbanna primeval forest as the origin, the grass and trees spread wildly, and finally formed a giant primeval forest with a length of more than 200 kilometers from north to south and a distance of more than 400 kilometers from east to west, occupying a circle of nearly 100,000 kilometers.

That is, the abyss-level alien beast gathering area, the Nanban primeval forest!

The huge jungle lies in the southwest of the land of China, where countless strange beasts gather, as the largest area of foreign beasts in China, the Nanban primeval forest is the undisputed first threat in southern China.

In the distance, a black dot at the end of the horizon appeared in the sight of Xiang Chen and the others, and ten minutes later, when the train finally approached, the original small black dot had turned into a huge steel jungle.

Li Zitong looked at the safe city in front of him, and his mouth grew up, as if he was going to swallow ten eggs raw.

Not only him, but Xiang Chen and the others all had similar expressions, and even Ji Songshi, who had always been calm, also had admiration in his eyes.

It's not that they haven't seen the appearance of the safe city, they are all people who have entered the wilderness, and they have naturally seen the appearance of the Nanjing safe city, but the Kunming safe city in front of them has subverted everyone's cognition.

The extremely towering city wall was devastated, with countless claw marks, chips, corrosion marks, and molten metal all over the city wall, and at this time, above the city wall, there was a huge mechanical arm running at high speed at every distance, and at a glance, there were countless such mechanical arms.

That's repairing the walls!

The walls were covered in clotted blood scabs and plasma mixed with dirt, and the entire wall looked as if it had been salvaged from a pool of plasma.

The land a few kilometers outside the city wall is also dark red, and the land closest to the city wall even turns red into a pitch-black color, spreading outward for more than ten kilometers before gradually returning to the earthy yellow color that the land should have.

Xiang Chen's eyesight is very good, and looking out of the train window, he can see hairs and pieces of minced meat everywhere on the ground.

"It seems that after the sweep, there are still remnants of alien beasts..."

"Teacher Song, how do I feel that the walls of this Kunming Safe City are so much higher than our Nanjing?" If you don't understand, just ask, Li Zitong wondered.

"The city wall of Nanjing Security City is 21 meters high, and that of Kunming Security City is about 43 meters, more than twice as high." Song Lu was also looking at the city wall outside the train and exclaimed, "Not only that, but the area of Kunming Safety City is equivalent to about three Nanjing Safety Cities. ”

"How can it be so bad?"

"Because of the war! There are also differences between safe cities, you who live in Nanjing safe city are lucky, in Jiangsu Province, there are no particularly large gathering areas of alien beasts, most of them are just some ruin city type settlements. Originally, some rivers in Jiangsu Province have been basically blocked after so many years of crustal changes and man-made management. ”

"As for the threat from the coast, because we are close to the safe city of the magic capital, plus we have a military deployment along the coastline, so it is not our turn to be the main force. Therefore, Nanjing Safe City can definitely be regarded as one of the few safe cities with the least war pressure in China. ”

After a pause, he continued: "On the contrary, because the south is adjacent to the Nanban primeval forest, Kunming has been fighting all year round, and is known as the southern Xinjiang barrier, and in modern history, there have been three times when the city gate was almost broken!" In the most dangerous case, the entire southern city wall collapsed. ”

"Well, what about later?" Li Zitong hurriedly asked, they all knew that the city wall was broken, and the ordinary people in the city were only in danger of being slaughtered.

"Nonsense, isn't it okay now?" Wang Shilei glanced at him like a mentally handicapped person.

"Later, it was the warriors and the army who blocked it with human lives... With the flesh and blood wall, the last line of defense was forged. ”

Everyone present was in awe, looking at the scarlet city wall, as if they could feel how tragic the war was.

"Fortunately, the whole country of China rushed to the aid of southern Xinjiang, and a large number of top warriors and mercenaries took the initiative to contact the Kunming government to ensure that they would arrive as soon as they needed it. Song Lu continued to introduce.

"Don't look at its large area, in fact, half of the south of the entire city is a military region, always vigilant against the Nanban primeval forest, and the north is where the citizens live. There is a saying in the Kunming Military Region, that is, if the city gate is broken one day, there will never be a soldier who dies after his father in his hometown, and the iron-blooded military soul can be seen. ”

"Over the years, countless strange beasts have died outside the southern city wall, countless warriors and soldiers have died in the mouth of the beasts, and the enmity between Nanban and Kunming has long been washed away and cannot be extinguished."

…………

The train enters Kunming Safety City and stops at the railway platform in Beicheng District, which is divided into two urban districts, the South City District is the Military Region, and the North City District is the People's District.

After getting off the train, among the crowds coming and going from outside the station, Xiang Chen noticed a difference again.

Kunming's citizens look more purposeful, the pace is fast, there are few people wandering the streets, and the folk customs are more vigorous.

Out of the station, the six people took a car, and the group rushed to Nancheng District non-stop.

In a makeshift barracks in Nancheng District, Xiang Chen and others got out of the car.

As early as on the way here, Song Lu explained the purpose of their visit this time.

The Nanban Forest is attacked twice a year by large-scale animal tides, and at the end of August, Kunming Safety City once again successfully resisted this invasion.

On weekdays, because of Kunming, the biggest thorn in the eye, the beast tide of the Southern Barbarians will only invest their combat power here, but after the battle, the beast tide is repulsed, and in the process of the return of the main force, there will also be small groups of foreign beasts that are scattered and wander around.

These small groups of exotic beasts roaming around are undoubtedly a disaster for the rest of the human settlements in Yunnan Province.

But few people are really willing to let them leave their familiar living environment and leave their homeland to go north, after all, this migration journey is even more dangerous, and I am afraid that they will die in the mouth of the beast before they reach other provinces.

The people in the gathering place did not dare to gather together on a large scale to resist, otherwise if they really attracted the attention of the Nanban Forest, I am afraid that the next time the beast tide will attack.

Therefore, they all chose to gamble, betting that they were not so unlucky, and that their gathering place was strong enough to resist these fleeing beasts.

In order to protect the safety of these fellow Chinese people, Kunming will launch this operation every year after the end of the beast tide.

Extermination!

It means to eradicate the pests that remain after the war.

The extermination operation was not a large-scale collective military operation, because the main force of the army still had to stay in the safe city to prevent the second counterattack of the animal tide, so it was a dispersal operation.

Use a squad as a combat unit, either to sweep away fleeing beasts, or to rush to the aid of an attacked human settlement.

In addition, the members of the squad are not limited to soldiers, in addition to the squad composed of soldiers, there are also students from Kunming University and Kunming Military Academy, local warriors in Kunming, and a large number of warriors from other places to form a warrior team.

This group of people from different places and with different identities will be temporarily formed into combat teams to carry out this pest eradication operation.
