Fang Nian and Duan Rui glanced at each other, and there was a hint of bitterness in their eyes.

"It seems that your grandfather didn't plan to leave us a way out, this is really a mysterious mechanism."

Duan Rui followed her grandfather to learn password cracking and design, so she naturally knew her grandfather's methods, and when she saw that there was no way out, she could only smile bitterly.

"Since you can only move forward, think about how you can open that iron door, which should be the only way out of this ice storehouse."

Fang Nian also nodded in agreement, but when they checked the state of the iron gate, Fang Nian's face became ugly.

"This iron door is very heavy, there are no holes inside, and it is obviously not a mechanical door, but a most ordinary iron door. The back is probably an ordinary padlock, which is very difficult to do, we don't have the tools in our hands, and we don't know where to start. ”

Duan Rui knocked on the surroundings of the door, sighed helplessly, and then looked at Fang Nian.

"Hey...... Aren't your fists quite hard? Why don't you give it a try? ”

Fang Nian was one head and two big, and he didn't know if Duan Rui did it on purpose, and he was still entertaining him at this time.

Although this iron door is not impossible to beat, if he is really a mechanical door, he now has mastered the dark power, and he can really try to damage the mechanical structure in it.

But now let him fight such an iron bump, wouldn't that kill him? This punch is not allowed to give him a discount on the bones.

Fang Nian smiled helplessly, and didn't take Duan Rui's words, and began to grope the wall to see if there was any other way out.

At this moment, suddenly the two of them heard a shuddering footsteps, and there was also a sound of keys colliding with each other.

"Someone's coming."

Before Fang could read anything, Duan Rui suddenly reminded him. Fang Nian was surprised for a while, his hearing had improved, and he had reached the E level. Therefore, Fang Nian could hear this sound like a mosquito and a fly, but he didn't expect Duan Rui to hear it too, and for a while, he really glanced at the girl in front of him again.

The sound soon came to the iron door, and after the key shook a little, a lock was heard, and then the door opened with a single click, and two men in gray uniforms pushing an iron cart walked in and began to carry the food on the shelves.

Fang Nian and Duan Rui saw that they were already far away from the gate, glanced at each other, and then successively drilled out of the ice vault from behind the gray uniforms, and suddenly a warmth hit them, and the two of them finally left the damn ice vault.

At this moment, the two appeared in a corridor, flanked by metal walls, and on the wall there was a row of windows, through which silver-white light was shining through.

Looking out the window, almost the same as they had seen before, the train was still moving at a very fast speed in a frozen ruin, with endless ice-cold snow ruins everywhere.

Duan Rui looked at the scenery outside the window in a daze, not knowing what he was thinking. But at this moment, a pair of big hands hugged her and quickly hid in a corner.

Duan Rui's pretty face was red when she was hugged by Fang Nian, and she broke free and said.

"What are you doing?"

Fang Nian covered Duan Rui's mouth and pointed to the camera that was spinning back and forth above the corridor, Duan Rui then understood, so he pointed to an iron door not far away that was exposed through a gap.

Fang Nian naturally understood Duan Rui's consciousness, so the two of them observed the camera again, and at the moment when it swayed, his figure flashed, just in time to shoot, and pushed the door and got in.

After entering, the two looked up and were stunned.

It was like a carriage in a boiler room, with boilers on both sides of the middle corridor, and in each room there were two men in gray uniforms, desperately waving huge shovels to fill the boilers with fuel like coal in front of them.

Fang Nian and the others observed that there were at least hundreds of rooms in this carriage, and almost all of them were repeating the same action, constantly adding fuel to the boiler.

At this time, the sound of the iron car moving behind Fang Nian and the two of them came again, and Fang Nian couldn't close it so much, he jumped forward flexibly, lowered his body and secretly opened a glass door beside him, stole out the two gray uniforms hanging on the fence inside, and quietly grabbed a ball of black fuel.

"What are you doing?"

Duan Rui saw Fang Nian hand over a uniform with a heavy smell of sweat, and said with a disgusted expression.

"Put it on."

Fang Nian smeared the pitch-black fuel on Duan Rui's delicate face, then quickly took off the clothes on his body and began to change his uniform.

Duan Rui snorted, eager to strangle Fang Nian to death on the spot, but thinking that Fang Nian was also doing it for their good, he could only endure the unpleasant smell of sweat, and began to put the clothes on his body while curling up his hair as much as possible to make himself look buried.

Soon, the two people who were transporting the food appeared behind Fang Nian Liangrao, and after seeing them, a somewhat distant man asked in confusion.

"You two are power groups?"

Fang Nian observed that there was a sign like a rice spoon on these two Rao's bodies, and a sign like a boiler on his own body, so he understood and replied.

"Yes...... Yes. ”

When the man heard Fang Nian's answer, he immediately said angrily.

"Then you don't fill up the fuel properly, what are you doing here? Why don't you go back to your furnace? The heart can't get the fruit cake at night. ”

Fang Nian and the two were stunned for a moment, but they still nodded, and then swept to a compartment without sparing, and then went directly into it, and began to learn to add fuel to the furnace without learning other actions.

At this time, Fang Nian and the two realized that these were not easy. The room was in the 30s under the charcoal roasting of the flame, and it was very difficult to do such heavy work in such a high temperature.

When the two of them pushed the food cart and left, Fang Nian and Duan Rui also stopped what they were doing and retreated from the room. Continuing to move towards the carriage in front of them, they knew that the only way out was to keep moving forward.

At this time, half an hour had passed, and there were still 7 hours and 30 minutes left before the ice circle appeared.

After walking for about 3 or 4 kilometers, Fang Nian and Duan Ruicai passed through the scorching power car and came to the next car, and after they came in, they found that this was a Chase Shop bedroom car.

There are thousands of beds in the carriages, like sleepers in a train. However, compared to the sleeper, the space here is more cramped, and the distance between each bed is less than 0.5 meters, and it is a group of 5 beds.

At this time, the entire carriage was almost full of people, and there were dried rags, old pants, and even some moldy sheets everywhere, like the so-called refugee camp in the polar Lingshi drama.
