Unable to decipher the password for a while, Lin Chi showed the note to the Blood Blade and the coach, and they also said that they didn't understand what it meant.

Lin Chi could see that "return immediately" should mean retreating immediately, but he didn't know what "the Iron Curtain fell" meant.

- In the old game decades ago, Lin Chi seemed to have heard of this name, but because he rarely had the opportunity to be "nostalgic", he couldn't remember what this "Iron Curtain" meant for a while.

At this time, the burden of answering the question falls on an NPC who is at home:

"What is the Iron Curtain?" Lin Chi asked Crazy Ivan a question.

"Ah......" The bald man wearing an eyepatch thought for a while, and then suddenly shouted: "I remember, it's our army's secret weapon!" ”

Hearing this, Bloody Blade and the coach also turned their attention to the bomb expert, and under the gaze of everyone, Crazy Ivan spoke at a very fast pace:

"The Iron Curtain device was successfully developed in 1943, as long as it is activated by enough electricity, it can generate a proton energy field in an area, so that all units inside are invincible! By the way, the human body can't withstand this kind of energy, so the humans within range will die instantly! I've seen the people inside die, it's horrific......"

“……”

As soon as these words came out, the three players present looked at each other, and they all saw a trace of excitement on the faces of the others:

If Crazy Ivan is right, this "Iron Curtain Device" is an artifact that can make mechanical units or buildings invulnerable, or instantly kill all human units in an area!

There is no doubt that the Iron Curtain Device can be regarded as a strategic superweapon, as long as they can seize control of that thing, their team will immediately gain a huge advantage.

Moreover, even if you can't activate that device for the time being, you can't let that thing be grabbed by other teams, after all, if you give up this strategic-level weapon to other teams, the threat to your own side is too great.

Thinking of this, Lin Chi spoke: "After handing in the task, how about we go and find this 'Iron Curtain Device'?" ”

"Agreed." The instructor raised his right hand.

"I'm okay with that." Bloodblade nodded immediately.

In the face of the hugely attractive "superweapon", this team, which has not been very harmonious, has finally reached an agreement.

After determining the next action strategy, they also trotted all the way back to the frozen sea where the nuclear submarine was located, and after returning to the ice, they launched a red signal flare for communication.

Soon, the rubber boat rowed back again, and the people who came down to meet Lin Chi and the others were still the two sailors from before.

Before Lin Chi could remember to speak, the other party had already grabbed his hand excitedly and shook it, and his unshaven face was full of bright smiles.

"Comrades, you have successfully completed your mission!"

The sailor said and took out a locator from his military coat, rudely stuffed it into Lin Chi's hand, and said with a heroic smile: "The Kursk submarine is ready to serve your comrades, as long as we receive a signal, we will immediately launch missiles to support you." ”

While getting the locator, Lin Chi's sight popped up a hint of the completion of the task:

Mission "Destroy the Crazy Chariot Factory" has been completed!

You have been rewarded with a mission: 1 Skill Point, Missile Signal Locator X1.

You have 30 Domination Points and 20 Prestige.

- The boss battle of the tank factory just now also provided him with 100 Domination Points and 100 Prestige Points. After the prestige point increased, the tone of the sailors became more friendly.

"Thank you so much." Lin Chi said and stuffed the locator into his backpack, pretending not to care, and asked casually: "Can we go on the submarine to visit?" The Airborne Forces want to see and see, you know. ”

As soon as these words came out, the expressions of the two sailors became solemn, and they shook their heads and said, "The captain does not allow outsiders to board the ship, sorry, comrades." ”

"Okay......"

Realizing that his idea of boarding the submarine would not be realized, before the sailors left, Lin Chi asked a second question: "Is there an iron curtain device on this island?" ”

"I'm sorry, but we are in the submarine force and don't know much about the army."

The sailor shook his head, said goodbye to everyone, and rowed back to the submarine in a rubber boat.

"This bunch of garbage." Bloody Blade cursed in a low voice.

Without any information on the location of the "Iron Curtain Device", they had to search the island on their own. However, searching the island on foot is undoubtedly a lot of time wasted and is likely to be dangerous.

What they need now is a working flying machine. As for where to find that kind of thing, even Lin Chi didn't know much, so he could only try his luck nearby first.

But before that, it's better to take a break.

This island in the Arctic Circle is currently in a polar daylight state, almost 24 hours a day. Even so, that doesn't mean the people on the island don't need to sleep.

If you want to survive this kind of cold and snowy battlefield, it is naturally necessary to get enough sleep. So here's the question:

"Which of you has warm sleeping bags and tents or anything like that?" Lin Chi turned to ask questions to the two teammates and received a negative answer.

At this temperature, if there is nothing to keep them warm, even if they can sleep, they will freeze to death without suspense.

"How about finding a cave for a fire." The coach speaks his proposal.

"Even so, it's better to have something to keep warm." Lin Chi turned around and walked towards the coast that had been baptized by missiles, and continued to think about feasible methods.

- There should be a lot of destroyed military facilities on this battlefield, and sleeping in that kind of place may be a good choice, but there is a risk of encountering the enemy.

- Ripping off enemy clothes to keep warm sounds like it should work, but even then, you need to find a safe position.

Lin Chi thought for a moment, and soon issued a new order: "We will camp on the other side of the woods. ”

"Huh, so you're thinking of yourself as the captain?" Bloodblade stared at him with scarlet eyes.

"What's wrong, do you have any comments?" Lin Chi asked.

"Whatever you want, it's better than that stuffy gourd." Bloody Blade pouted at the coach: "There is a personal command, and I am relatively idle." ”

Lin Chi looked back at the "one-armed hero" behind him: "The mechanical technology on this battlefield seems to be quite advanced, you may be able to get a mechanical arm to install on the right." ”

Hearing this, Blood Blade, who had always had a bad attitude towards Lin Chi, finally smiled reluctantly: "If only there was a mechanical hand, it would be more convenient for me to kill people......

Seeing that the originally bad relationship between the two seemed to have improved, an imperceptible smile appeared on the face of the coach who walked at the back.
