In the afternoon, Zhang Zhen was woken up by Sakura, the Gopher Gang found the entrance and was about to open, he got up from the bench, took a shower, changed his clothes, and rushed over.

The top and sixth floors of the fortress were basically cleared, and all kinds of turrets and protective shields were clearly displayed, and from a distance it looked like a steel furious beast.

Gu Yicheng excitedly escorted Zhang Zhen to climb up, pointed to an iron-like bulge on the sixth floor and said, "After Elder Cai's research, it should be an emergency exit, and you can remove the mechanism from the outside and open it." ”

Zhang Zhen swept his eyes back and forth, originally he could go up to the top floor by stepping on the soil layer, but now he can only climb some protective fences or ladders, and the top floor looks like there should be a door, he said: "Other doors can't be opened?" ”

Cai Channel: "The normal door can only be opened from the inside after losing power, and it takes a lot of time to cut if you want to open it outside, I have seen this door, after removing the outer iron shell, you can find the ejection mechanism, which is the easiest to open from the outside." ”

"Okay, let's go." Zhang Zhen nodded, and stood aside to look at the land fortress that showed some true faces.

It seems that opening the door is also a very important ritual, Cai Tong commanded the man carrying the chemical fuel tank on his back to start cutting the iron shell, the orange-red flame burned a white eye as soon as it touched the iron shell, but it took a long time to melt a two or three centimeter long opening.

Zhang Zhen looked at the fortress for a while and a half will be difficult to cut and turn to the fortress to see, the damage to the fortress is not as serious as imagined, the traces of corrosion in many places are very light and can see the patterns, some of the forts are incomplete, some are still intact, there is a circle of one-meter-wide iron fences outside the sixth floor is basically unchanged, and it is estimated that there are sixteen forts around the sixth floor alone.

Gu Yicheng followed and introduced: "This floor is a rest area, the turrets can also be operated manually, behind those closed small windows should be the rest room, and there are also some turrets hidden under the iron wall, and the super artillery on the top floor is stuck in the cockpit, the city lord can take a look, it is the largest vehicle-mounted artillery I have ever seen." ”

Zhang Zhen nodded, and climbed up the seventh floor along the ladder, the seventh floor was smaller than the sixth floor, the turret was more of a multi-muzzle Gatling, and occasionally a window did not close the defensive armor, and it was scattered and couldn't see anything clearly.

Climbing up to the top floor, I saw that the original highest place was actually a damaged radar, and there was a hatch several meters long near the radar, the long hatch was open, and a huge cannon with a thick muzzle facing the sky was basically revealed under the soil.

"According to Cai Hufa's research, this may be an electromagnetic cannon, the power can penetrate the city wall six or seven meters thick, although the cannon body is stuck, but the base can not see the damage, and the internal estimate is also very complete, this electromagnetic cannon repair should be usable." Gu Yicheng said excitedly, this electromagnetic cannon alone is worth tens of millions.

Zhang Chao scanned the lower artillery compartment with his glasses, and there were indeed no obvious traces of damage in it except for some soil, and the main part was still hidden under the iron shell of the fortress, as Gu Yicheng said, most of the electromagnetic cannons could be used.

He nodded slightly, he couldn't show too much joy, now this fortress is selling for money, if the Gopher Gang wants hundreds of millions, it will be a bit tricky, after all, there is not much money in hand, and it will take time to sell goods to make up.

With radar and electromagnetic guns, the land fortress in Hongcheng can be said to be certain, and the degree of damage inside determines the ultimate value of this land fortress.

After waiting for nearly two hours before the iron shell was cut off, revealing another iron door, on which a lot of machinery without any rust appeared, Cai Tong personally went into battle and began to study and fiddle with those mechanical parts.

He burned a hole a few centimeters in the gap between the parts like a needle in the eye of a needle.

"Bring the explosives."

The subordinate next to him hurriedly took a bag for Cai Tong, Cai Tong took it and opened it, took out some black, gray, white and yellow gunpowder from it, carefully sprinkled it layer by layer on a piece of plasticine-like gelatin, and then took out a short iron rod like a pen refill and pressed it on one end to carefully roll the gelatin back.

"All to the left and right." Cai Tong said as he carefully dispersed the thumb-thick handmade explosives into the small hole.

Zhang Zhen stepped aside, and he found that the white iron needle was slowly turning red, as if a fire was burning.

As soon as Cai Tong pretended to be busy, he flashed to the side, and heard a bang under the iron door, then a sound of gear machinery turning, and then a boom, an iron door for people to bend over flew out, and then slammed into the dirt by the fortress.

Zhang Zhen looked at the door for people to bend down and couldn't help but clap his hands and said, "This is really wonderful, I didn't expect you to have such a subtle means." ”

"There may be poisonous gas in it, so let's put the robot in first." Cai Tong wiped the sweat from his face and walked towards Zhang Zhen with a smile: "The city lord has won the prize, and if you want to survive in the last days, everyone has to have some means." ”

Zhang Zhen watched Cai Tong's subordinates put the robot bee and spider-like robot into it, and also put a scout bee in casually, took out a cigarette and handed it to Cai Daodao: "Cai Protector is modest, it is not easy for people who have no ability to enter this fortress. ”

Cai Tong took the cigarette with both hands excitedly, and nodded excitedly when he saw Zhang Zhen lighting the fire to help him light it, and took a puff of enjoyment on his face and said: "The city lord looks up to Cai Tong, Cai Tong doesn't tell lies, people who can open this kind of door can't find a second one in the last days, and no one else wants to open it except me, unless it takes a few days to completely cut a hole in the fortress." ”

Zhang Zhen smiled and nodded, he liked to fiddle with mechanical people since he was a child, and his ambition when he was very young was to repair TVs, and worship those who could repair TVs as idols.

"There's a picture, it's been unventilated for a long time, there are toxins everywhere, the rest area is messy, and there are corpses in the corridors, it looks like they starved to death or committed suicide, and no traces of strange beasts have been found for the time being." A guy in charge of manipulating the robot was busy reporting.

Cai Tong hurriedly went over and enlarged the picture and projected it so that everyone could see that the spider robot was marching in the passage of the lounge, some of the corpses in the passage were withered and decomposed, but the limbs looked intact, the sloping fortress made it messy inside, and some people died on the beds in the lounge, with guns in hand.

"Go to the patio and see if you can go up to the top floor or down to the fifth floor." Cai Tong instructed.

The operator nodded, directing the robot bee to fly quickly, and was about to reach the elevator area with a cylinder in the center, when suddenly the robot bee was uncontrollable and suddenly hit one side with a sudden shake and lost the signal.

"There may be an out-of-control magnetic field that allows the spider to crawl slowly." Cai Tong smoked while commanding in an experienced manner.

Another operator nodded, and slowly manipulated the spider robot to crawl towards the elevator area, forming a real-time stereoscopic image of the surrounding environment with several eyes.

"It's out of control, it's being sucked away!" Fang approached the elevator area and the operator shouted.

I saw that the screen began to flicker, and the spider was obviously sucked into a certain object in a circle out of control, and the signal was lost after a few seconds.

Zhang Zhen's glasses also received a warning that the reconnaissance bee was missing.

Cai Tong took a hard puff of cigarette, and the fireworks scorched the filter before he reluctantly threw it away: "The fortress uses a maglev elevator, and it is estimated that the elevator has malfunctioned and the magnetic field is out of control." ”

Zhang was shocked: "Isn't that a lot of electronic equipment to be destroyed?" ”

Cai Tong frowned and said: "The impact doesn't seem to be very big at the moment, if the fortress is really the most selected pre-apocalyptic technology, then many equipment will have magnetic field protection, and it may not be too damaged, now we must detoxify first and then the personnel go in to explore." ”
