Seeing that the bear child's mood had stabilized, and there was no fear or hesitation in his eyes, Chu Xun was also slightly relieved in his heart.

It's a team race, and if the bear kid insists on quitting out of fear, he's in big trouble.

"Brother, what should we do next, are we going to continue to look for allies?" Hopefully, this kind of thing will not be able to contain once it sprouts, so at this moment, the bear child is eager to win the game immediately, and then go to Sky City to find news related to his parents and "home".

"No, it's almost dark now, and we must find a place to hide and spend the night." Chu Xun shook his head, then looked at the sky that was almost completely dark, and said with a somewhat solemn expression: "Although I don't know much about mutant insects, I know that most insects are nocturnal creatures, and the vision is unclear at night, so scurrying around in this situation is tantamount to killing yourself." ”

"Brother, you know so much......" Hearing Chu Xun's words, a trace of amazement suddenly appeared on the bear child's face.

"Is this common sense...... " Looking at the look of amazement and adoration of the bear child, Chu Xun was suddenly a little speechless, then shook his head, opened the tactical backpack, took out the map of the dead city in the bag, and looked at it carefully.

In previous battles, he had discovered that the buildings in the dead city had somehow become extremely fragile, and with a little exertion, they would completely crumble like building blocks and turn into rubble.

Naturally, such a building would not be able to resist the Zerg, and even if he was not careful, they could be completely buried by the collapsed building, so he had to find a strong and safe place to spend the night.

"I hope I can be safe and sound tonight......" Seeing that Chu Xun was seriously looking at the map, the bear child didn't dare to disturb Chu Xun, so he could only open the tactical backpack, take out the compressed jerky and drinking water in the bag and start eating.

"There it is!" Chu Xun had a good memory, so it didn't take long for him to memorize the map of the entire city in his mind, and at the same time, he also found the hiding place he needed from the map.

"Found it?" Seeing Chu Xun find a hiding place, the bear child suddenly perked up, then stuffed the food and drinking water back into his backpack, and asked curiously, "Brother, where are we sleeping tonight?" ”

"Battle Castle!" Chu Xun smiled slightly, then pointed to a mark on the map and said, "According to the map of the land, the nearest battle fortress is less than two kilometers away from us. As long as the fort isn't completely destroyed, we'll be able to sleep there tonight. Let's go, it's going to get dark, we have to hurry, I don't want to spend the night outside. ”

Speaking of this, Chu Xun also put away the map, then turned around and walked forward. And the bear child immediately put on his tactical backpack and trotted to keep up with Chu Xun.

The wars of the end times are extremely cruel, because whether they are zombie creatures or mutated creatures, they besiege human cities for only one purpose, that is, to turn humans into their own food.

These terrible and murderous guys never need to be captured, plus there are so many of them, every battle is a siege, so once the city is captured, then the surviving humans don't even have a chance to break through, and can only choose to fight to the death.

Either fight off these mutated creatures and zombie creatures, or you can all die in battle, and there is no other choice!

And the battle fort was built under this circumstance. This kind of structure is very similar to the pre-apocalyptic bunkers, the overall size and scale are not very large, but they are extremely strong, and there are many of them, like nails scattered over the entire city's defense nodes.

Once the walls are lost, the remaining combatants and civilians retreat to the nearest fort, where they can defend and counterattack the enemy with its sturdy defenses and built-in automatic weapons. If the zombie creatures and mutated creatures were to move forward, they would have to pull out the nails one by one. And in this process of pulling nails, these zombie creatures and mutated creatures not only have to pay a heavy price, but also take a lot of time. In this way, the survivors in the rear will also be able to reorganize the defensive line and then better defend and counterattack.

The most important thing about the fort is the defense, most of the forts are made of special cement, and there are even many cities that will cover the surface of the fort with a layer of alloy to ensure the safety and defense of the fort. Therefore, Chu Xun firmly believed that these strong fortifications would not be as fragile and vulnerable as the other buildings in the city.

The distance of two kilometers was not too far for people with abilities like Chu Xun and Bear Child, so they quickly found the battle fort according to the map.

Thankfully, because the sea of worms that destroyed the White City was artificially controlled, these terrible bugs did not attack the fort as stupidly as people imagined, but directly skipped these fortifications that were more than defended but had insufficient offensive capabilities, and drove straight into the city to completely annihilate the survivors who retreated into the center of the city.

After annihilating the survivors in the center of the city, the remaining bugs were also stationed in the city under the man's orders, turning the originally huge white city into a huge worm nest and completely trapping the survivors in the battle fort.

In the end, the survivors trapped in the fort either starved to death due to the lack of food and water, or chose to commit suicide at the last minute or launched a suicide breakout. In this way, most of the battle forts in this city are well preserved, which also gives Chu Xun and other participating students a little respite.

"Fortunately, this battle fort has hardly been damaged, and it seems that I can rest peacefully for the night today!" Looking at the almost well-preserved battle fort in front of him, but there was some rust on the surface, Chu Xun suddenly breathed a sigh of relief.

The battle fort is not large, a total of fifteen or sixteen meters high, and the overall structure is very similar to the bunker that Chu Xun had seen on the earth before, it is cylindrical, and the diameter is no more than ten meters.

The surface of the fort is almost entirely covered by a thick layer of alloy, and underneath the alloy is a special cement that is extremely tough, and the defense can be described as extremely strong. Only at the bottom of the fort is a heavy steel gate, which is covered with some fine wiring, and it is obvious that this gate can create a powerful power grid to resist foreign invasion when it is electrified.

There were no windows above the fort, only small ventilation holes. There are also several layers of defenses and filtration behind these vents, so even survivors in the fort can be safed from the poison gas attack of mutated creatures.

In addition to the vents, there are also a number of automatic defensive weapons on the battle fort, including six automatic multi-barreled machine guns with a caliber of 30mm. However, due to the depletion of energy throughout the city, these automatic weapons have become mere decorations like the power grid on the steel gates, and cannot play any role.

"Brother, the door is closed, how can you get in?" Looking at the closed alloy gate under the battle castle, a look of worry suddenly appeared on the bear child's face. This alloy gate is extremely heavy at first glance, maybe it weighs tens of tons, and how can this gate be opened without energy support.

"Don't worry, leave it to me!" Chu Xun smiled slightly, then patted the bear child on the shoulder, and walked to the front of the alloy gate.

"Whew!" After taking a deep breath, Chu Xun's arms also suddenly exerted force, and then he saw that his originally muscular arms also expanded rapidly as if they were inflated, bulging terrifying muscles like reinforced concrete, and at the same time, the nails on the fingertips also suddenly swelled, and flashed a faint coldness, like a sharp scimitar.

"Damn, brother, you still have this hand?" Seeing Chu Xun's arms swell nearly twice suddenly, the bear child was suddenly startled and exclaimed.

"Haha, what is this, I still have a lot of things!" Seeing the bear child's surprised and adoring look, Chu Xun suddenly laughed, and then with a wave of his arms, his sharp nails were inserted into the crack of the steel gate like a blade.

"Brother, don't you want to ......?" Seeing Chu Xun's movements, the bear child was startled again, and an unbelievable look appeared on his face.

"Drink!" However, before the bear child's words fell, Chu Xun had already let out a loud shout, and his arms suddenly exerted force. Then, in a burst of harsh metal friction sounds, the huge alloy gate was finally opened by Chu Xun, and then slowly pushed to both sides.

And as the door slowly opened, countless rusts and debris also spilled from the top of the alloy gate, and at the same time, an extremely turbid and inexplicable stinky air flow also poured out from the door, making Chu Xun couldn't help but sneeze a few times.

"Brother, you are simply a god......" Seeing that the alloy gate weighing dozens of tons was actually opened by Chu Xun with brute force, an expression as if he had seen a superman suddenly appeared on the bear child's face.

He couldn't imagine that Chu Xun's strength had reached such a terrifying level!

"Haha, don't be a sycophant, let's go in first!" Chu Xun brushed the rust off his head with his hand, then glanced at the sky that had been completely blackened, and said, "Now that the sky is completely dark, the nocturnal mutant insects should also start to move, I'm worried that the movement here will alarm them, so we'd better go in quickly." ”

"Yes!" Thinking of the terrible sea of insects he saw today, the bear child shuddered violently, then nodded, and immediately walked into the battle castle.

"I don't know how many more people will die tonight......" Looking at the dark sky outside, Chu Xun sighed slightly, and then exerted his arms again. Suddenly, in a series of harsh metal grinding sounds, the incomparably heavy alloy gate also began to slowly close, and finally closed together in a violent roar.

At this moment, the night is already deep.

And this "Worm City" is about to show its most terrifying side!
