In the secret base where Irene's detention is held, the patrol pattern of its guards is usually rotated every four hours.

From midnight to four a.m., it is the first shift of the day to patrol. As a rule, each shift is the most energetic, excited, and alert at the beginning of the shift. And as time passes, drowsiness, cold, and fatigue will slow the guards to relax.

Therefore, in order to increase the probability of success of the operation, Haoyi and the others set the time to enter the base at two o'clock. This ensures that the guards' alertness has begun to decrease by this time, and that there is enough time for rescue operations before the arrival of the next shift of new guards.

"Buzz!" With a dull sound, the gate of the base, disguised as a rock wall, buzzed open, and Haoyi probed his head to look inside, and saw that there was no shadow of a guard in the passage behind the gate, so he tiptoed in.

"Hey, big brother, you don't have to be like this, okay?" At that moment, the voice of Agent 250 came from his helmet headset. In order to facilitate the operation, the two of them adjusted the internal communication channel of the CMC armor to a channel that only the two of them knew, so that during the operation, they did not have to worry about other guards overhearing the conversation between the two.

Although Agent 250 was behind Hao Yi, for the sake of secrecy, he still said to Hao Yi through the armor communication channel, and said in a low voice: "Don't forget the identities of the two of us, and now we are also guards in this base." In the unseen corners of this passage, there are hidden surveillance cameras. The more sneaky you are, the more likely you are to arouse the suspicion of the surveillance officers in the control center! ”

After that, the 250 agent who was originally behind Hao Yi walked around Hao Yi who looked back at him in stunned astonishment with his rifle in his arms, and swaggered down the passage.

"Ya, if you don't say it earlier, it will hurt Lao Tzu's heart to be raised to his throat!" Hao Yi scolded in a deep voice in the communication channel, and then followed Agent 250 in a leisurely manner.

"Don't forget, I'm also the squad leader of the guards here!" Agent 250 walked forward and explained to Hao Yi in the communication channel: "I know the specific location of the guards on duty on the first floor of the base! Don't worry, as long as you take it easy and follow the normal patrol of guards, the officers in the surveillance room will not suspect your identity under normal circumstances. Of course, I won't take you to the wolf's den! ”

"Even if you want to take Lao Tzu to the wolf's den, Lao Tzu has to send you to feed the wolf first, and then burn the wolf's den on the dog's day!" Haoyi took advantage of the situation to say a word, which made Agent 250 suddenly have black lines on his face again. Although he had only been in contact with Hao Yi for less than half a day, judging from the behavior of this goods, Agent 250 had no doubt that Hao Yi was really capable of doing such a thing. Thinking of this, Agent 250 shuddered coldly, shrunk his neck, and no longer dared to make a noise to provoke Haoyi, a plague-like guy, and was engrossed in leading the way.

After entering the first floor of the base, you must first pass through the warehouses, canteens, medical rooms, etc., and then pass through the camp of the Marine Battalion to reach the elevator to the second floor.

"If I'm not mistaken, there should be two sentry posts at the front of the storehouse!" Coming to the first corner of the passage, Agent 250 looked up, and felt that there were no cameras here, so he waved his hand at Hao Yi, motioned to stick it to the base of the wall, and then whispered to Hao Yi through the headset.

"Just two? That's easy to do, let's just do it one by one! Hao Yi replied nonchalantly, and then took out the spike pistol from the armor of his leg, opened the safety with a soft click, and loaded it.

"I'm X! You don't want to just rush over and surprise them, do you? Looking at the movements of Hao Yi's hands, Agent 250 couldn't help but widen his eyes and said in astonishment.

"Do you think Lao Tzu is as stupid as your code name?" Haoyi pursed his lips and said a very connotative scolding, and in the extremely complicated expression of Agent 250, he leisurely took out two special mufflers for spike pistols from the treasure chest-like backpack behind him, handed one to Agent 250, and asked, "I don't need me to teach you how to use it, right?" ”

Agent 250 took the muffler, and while also taking out his pistol, his face flushed slightly, and wanted to explain to Haoyi: "That, about my agent codename, it's actually like this......"

"Okay, when we're done with business, we have a chance to survive, and you can tell me your legendary story again!" Hao Yi waved his hand to interrupt the words of Agent 250, held a pistol equipped with a muffler, slowly touched the corner of the passage, looked out, but said in surprise: "Huh? Didn't you say there were two sentry posts? Why is there only one left? ”

"Huh?" Agent 250 had just loaded his pistol, and when he heard this, he hurriedly followed him to the corner of the wall, and when he looked out, he saw a heavily armed Marine leaning against the door of the storeroom about twenty or thirty paces ahead. Although, he was holding an assault rifle in his hand, and he couldn't see the expression of the holographic helmet mask clearly, but judging from his frequent nodding posture, this thing must be napping.

"Ah, there are still absenteeism?" Agent 250 was puzzled and cursed in frustration.

"I said, we don't care how many fucking sentry posts there are, anyway, why don't we just kill them in the past?" Haoyi took a closer look at the scene in the passage, and said to Agent 250: "I don't think there is any other way to bypass this, even if we turn into birds and fly over, who dares to guarantee that this thing will suddenly wake up and pick up a rifle and surprise the two of us?" ”

"I think it's better to do it without hands, it's better to do it with biedong hands. Otherwise, if the other guards find the body, the whole base will explode. Then we'll probably not even have a place to escape. Agent 250 frowned, shook his head and denied Haoyi's "reckless behavior", and muttered: "As far as I know, the entire base is just one exit. As long as they get stuck here, even if we can turn into birds, we won't be able to fly out! Let's put the gun away first and see if we can get through it. With that, Agent 250 hid the silencer-mounted pistol back in the armor on his legs.

"Alright! I'll believe you once for the time being! Hao Yi pursed his lips and muttered a rather depressed sentence, and then put away his pistol as well.

"Let's go!" Agent 250 beckoned to Haoyi, leaned out, crept along the wall of the passage on the other side away from the guard, and tiptoed forward. Seeing this, Haoyi also hurriedly held his breath and followed step by step.

While walking, the two stared nervously at the guard who was dozing off, and secretly prayed in their hearts that this thing should not wake up at this time, and it was best for Zhou Gong to give him a beautiful woman and let him be immersed in the gentle township of dreams.

"Click, click!" Rao is Haoyi and Agent 250 have already tried their best to slow down, and the sound of two pairs of armored combat boots gently touching the ground is still very clear in this quiet passage. Finally, seeing that they were about to leave the dozing guard's line of sight and enter the corner of another passage, Haoyi and Agent 250 suddenly felt a little more relaxed.

“zhanzhu！” However, at this moment, there was a sudden loud shout behind him, which startled Hao Yi and the two of them to stop in unison.

"What are you two doing? The squad? Obviously, even if Haoyi and the others didn't turn around, they knew that this rough voice must have come from the mouth of the guard.

"You are a second-class vegetarian fish fillet, don't you know Lao Tzu?" Agent 250's mind flickered, and then he heard the guard's voice. This was a corporal from another squad named Su Yuping, who was nicknamed Vegetarian Fish Fillet by the other brothers in the battalion. Agent 250 has dealt with this guy a few times, and he is half familiar with him.

As he spoke, Agent 250 slowly turned around, blocked Hao Yi with his body, and made a gesture behind Hao Yi with his left hand behind him. Hao Yi comprehended, and hurriedly took advantage of the cover of agent 250 to quietly find the rifle with a silencer, hid it behind him, and followed agent 250 step by step towards the guard.

“zhanzhubiedong！” The guard, apparently still alert, held his rifle and pulled the bolt with a click, and then shouted a loud reprimand: "Which squad are you two?" What is your name? Open the mask! ”

"I'm X you dog-day vegetarian fish fillet! Can't even hear Lao Tzu's voice? Agent 250 frowned, subconsciously stopped, and then opened his helmet and mask, pretending to be very angry, and yelling.

"Captain Pig? It's you! After seeing the face of Agent 250 clearly, the guard suddenly came to his senses, then lowered the muzzle of the gun, and also opened his mask, revealing a young face, and asked with a smile: "You are so late, why don't you sleep and run around?" ”

"Ya, Lao Tzu's surname is Zhu, not a pig, don't call Lao Tzu Captain Pig fucking, just call Captain Jack?" Seeing the guard put down his rifle, Agent 250 breathed a sigh of relief, showed a very angry expression, and continued to walk towards him while shouting at the guard named Suyu Flakes.

"Yes, yes, Captain!" The vegetarian fish fillet was scolded by 250 and nodded again and again, and asked with a smile: "What, where did you come back from so late?" He saw that Agent 250 and Hao Yi were walking towards the inside of the base, and naturally thought that they must have just returned from the outside.

"I'm X, didn't I eat bad stomach during the day, and I almost didn't burp Lao Tzu?" Hearing the guard's questioning, Agent 250 had an idea, and opened his mouth to say nonsense: "This brother of mine said that he knows some herbs that specialize in treating dysentery, so he took me out to find them together!" ”

As he spoke, Hao Yi and the two had already come to the guard, one left and one right faintly forming a trap on him, Hao Yi's right hand was behind him, and his fingers were already hooked on the trigger.

"Oh, I see!" The guard said suddenly, but then suddenly frowned and wondered: "Hey, it's not right! It's the middle of the night, can you still see the herbs outside? ”

"Hehe, what do you say?" Agent 250 suddenly showed a strange smile, and with his hand behind his back, he gestured to Hao Yi and signaled his move.

"Woo woo......" While the guard was stunned, Agent 250 strode forward, holding down the rifle in his hand with one hand and covering his mouth with the other. Haoyi's figure on the side launched almost at the same time, snatching the rifle from the guard's hand with one hand, and the spike pistol with a silencer was pressed against the guard's forehead. I heard a sound like a watermelon exploding, and the guard's head suddenly blossomed, and the red and white brains scattered everywhere splashed all over his helmet, and even Haoyi and the two of them were splashed a lot.

"Click, click!" And just as the two of them had just eliminated the guard, at the corner of the passage in the distance, there was a crisp movement of combat boots stepping on the ground.
