The four teams fought and retreated, and there were more crazy rats than Rowan had imagined, and now the rat corpses were almost all over the hall, looking like a pool of blood and flesh from a distance, like a hellish scene.

However, the number of rats seemed to be increasing unabated, and waves continued to rush towards the Yongdao where Rowan and them were, and the battle situation did not improve much because of the arrival of the four team members, on the contrary, there was a possibility that the whole army would be wiped out.

The four teams retreated all the way along the Yongdao, and at this time, a steel gate with the name plate of "Kwantung Army Epidemic Prevention and Water Supply Headquarters" appeared on the left side of everyone's field of vision, and Rowan couldn't care much, shouting: "Zulong, the sea is open!" ”

Then one step rushed to the sea to take over the machine gun, this heavy machine gun was originally intended to be equipped by the military on the helicopter ground heavy fire lethal weapon, six barrels 30mm caliber, the rate of fire reached 2600 rounds / minute, the bullet chain continued to supply ammunition, but used for research and development excessive pursuit of firepower, resulting in excessive recoil, and the current military helicopter can not be used normally after loading, because continuous high-speed shooting must bring continuous recoil, which makes the helicopter will have a slight yaw, although only a slight yaw, But it will bury the hidden danger of crashing, which is absolutely not allowed in the military.

He had no choice but to give up this idea, but it was a fulfillment of the sea, and he couldn't cope with this recoil at all.

However, this thing is in the hands of Luo Wen, it is simply a 70-kilogram child lifting a 70-kilogram barbell, and he can't control it at all, fortunately, Zu Long can barely fire after opening the door lock with Luo Wen, but the accuracy and rate of fire are much worse, and the four teams are even more struggling for a while.

The sea stood in front of the steel gate and glanced at the slide below, then grabbed the handle fiercely and took a deep breath, and then suddenly screamed without warning, and with the scream, the musculature of the sea suddenly inflated instantly like an inflated balloon!

The muscle lines suddenly bulged up, every blood vessel became extremely obvious, the two arms were wrapped by the swollen muscles like twists, and the originally loose combat uniform pants were also crunched at the moment, and the whole body was red as if they had just taken a hot bath.

The sea arms are struggling, staring hard at the ground to pull the gate horizontally, the slide under the door has not been opened for a long time, and it is jerky at the moment, but with the force of the sea, a string of sparks burst out on the slide, the piercing friction sound makes people's hearts itch, inch by inch stick to their position, but finally did not survive the strange force of the sea, the sea gritted its teeth, as if venting a swear word, this heavy gate was barely opened a narrow slit!

Everyone retreated into the door while attacking the rats, at this moment the sea did not care about the swarming rats to bite, when Rowan was the last to enter the house, he hurriedly closed the door, Rowan and Zulong were afraid of accidentally hurting the sea and did not dare to fire again, only Hexiang a soft gun flew up and down through the crack in the door, the head of the gun was chaotic to prevent the rats from taking the opportunity to enter, Xing Song used a bow and arrow to block the rats that slipped through the net, with the sea full of swear words and the door "click" closed, everyone finally breathed a sigh of relief.

Everyone sat on the ground panting, listening to the incessant crashing sound outside the door like a bullet hitting the door, and Rowan leaned against the door for a moment of peace.

Rowan took off his almost torn alpine combat uniform, and hurriedly began to look at the environment he was in now with the help of the shoulder lamp.

This is a natural cave, the cave is not big, the cave is surrounded by stalactites and stalagmites, the shoulder lamp shakes and looks brilliant, but the difference is that the ground under the feet should be artificially leveled, cushioned with fine sand and stones, soft but strong to step on.

A dark cavern stretched into the distance, like an abyss with no end. Rowan listened to the movement outside, as if the number of rats would be much less, so he ordered to rest in place.

The sea leaned over to Luo Wen and hurriedly asked, "Team Luo, what's the matter?" What the hell is this? It's a rat spirit, isn't it? ”

While adding bullets to the wheel, Rowan briefly recounted the experience of coming down with the ancestral dragon, and the sea looked at Rowan with wide eyes: "What the hell! Is this 731? Dog Day is still coming to my doorstep! ”

Xing Song counted the arrows in the quiver and said to Luo Wen: "I also saw a few similar nameplates along the way, but I have never heard that Unit 731 has a secret base here. ”

Xing Song took out a leather case from the tactical bag behind his back, which was none other than Rowan's. He took out two bundles of lancets from his bag and handed them to Zu Long, who took the flying knife and disappeared in his hand, and the sea stared at it for a long time without seeing why.

For the first time, Rowan opened the suitcase in front of everyone, and the suitcase was divided into two layers, neatly arranged with many things, but except for a card slot for a three-barreled revolver and a small number of bullets, he didn't know anything else.

Rowan loaded the bullets with orange warheads into the rapid loader one by one, and took out a short black rod from the lower layer of the suitcase and stuffed it into a card slot in front of the tight-fitting combat suit, then stopped and looked at everyone and said: "Actually, I was thinking about it from the first time I saw that brand, why do we see the famous brand 'Kwantung Army Epidemic Prevention and Water Supply Headquarters'?" ”

The sea picked his nose and asked rhetorically, "What do you mean?" Is it still written that the Stuffy Donkey Community Neighborhood Committee? ”

Xing Song glared at the sea, looked at Rowan and said, "What do you mean......"

Rowan looked at the sea and asked, "What is the name tag on my office door?" ”

The sea wondered if the captain had let the rats gnaw on his brains? "What's wrong, Captain? You don't have the captain's room of the fourth team written on the door......"

After the sea finished speaking, he was stunned, Zu Long rolled his eyes and looked at Luo Wen with a smile, only Hexiang wiped the head of the gun unhurriedly.

Yun Yi patted his head one by one and said, "Yes! No one will use their full name in their own home! Just like in our office, they are all the first team of the Investigation Section, and the third team of the Information Department is called that, if it is from the same department, it is normal to directly say that the first team or the third team is normal, and no one says the full name, just like your door plate does not say 'Captain Room of the Fourth Team of the Investigation Section of the Institute of Mysterious and Unnatural Events'! ”

"Yes, the name of the Kwantung Army's epidemic prevention and water supply headquarters is for outsiders to see, and it is to cover people's ears. But for people inside Unit 731, who doesn't know what they do? Even here there shouldn't be any number signs for the sake of concealment. But this brand has been seen many times, and most importantly, ......"

Rowan paused for a moment and looked up at everyone, "We can actually understand!" ”

Everyone was shocked after listening to it, the reason why the words on this name plate can be understood is because it is Chinese Chinese characters!

In a secret Japanese military base, Chinese name plates have been repeatedly seen, which is obviously a very unusual situation. The sea frowned and stared at a raised stone on the ground and muttered, "Grandma's, this was originally a Japanese military tourist attraction open to Chinese!" ”

Xing Song thought for a while and said: "This is strange, the mission performed by Unit 731 in that era is absolutely top secret and inhumane, even in such a special historical period, it is absolutely impossible to face external public opinion, so there is absolutely no reason for the Chinese who enter here to get out alive, since this is the case, there is no need to make this kind of brand, because no matter what the Chinese who come here see, they will eventually die!" Isn't it redundant to have a back and forth? ”

"That's right! So, unless someone can get out of here, and it's safe to get out of here with the consent of the Japanese. Rowan lit a cigarette and said.

"I know!" Dahai stared at Luo Wen: "Dog Day must have jointly developed a project with the local government at that time, and in order to deal with the inspection team of the cooperative government, so many famous brands were specially made to hide people's eyes!" ”

Luo Wen took off his glasses and squeezed the muscles between his eyebrows with his hand, waved his hand and said: "In terms of the situation at that time, the Japanese Kwantung Army controlled almost the entire Northeast China, and the puppet government of Manchukuo was just a puppet of the Japanese, and no organization or individual could bargain with them. But you are right, that is, there are indeed Chinese who can come here and go out, so these nameplates are needed to cover up the true identity and purpose of Unit 731. ”

"Deliver food!" The sea said categorically, "You have to eat, drink and Lazar on a dog day, there is no rice and white flour under the ground of this deep mountain and old forest, and you have to eat on a dog day!" It must have forced the common people to come here to deliver food to them, and if they send food, they can't be killed, because they must save their lives and deliver it next time! ”

Xing Song shook his head: "It shouldn't be, the Japanese have no reason to let the people who send them to the military base go down to such a deep military base, if I build such a secret military base, I will definitely raise supplies from elsewhere, and then transport them here in a hidden way, it is impossible to let the people swagger in to send things and then let them out, and the famous brands are scattered here in many places, if it is not necessary, I will definitely not let the people come around in such a big circle, that is almost all the secrets will be spread out in front of the comers." ”

Hearing this, Luo Wen's eyes suddenly opened, and he hurriedly put on his glasses and stared at Xing Song: "What did you just say?" ”

Xing Song was stunned by Luo Wen's question: "What do you mean?" ”

Rowan placed the shoulder lamp on the ground and beckoned several other people to also surround the shoulder lamp, forming a sand table surrounded by lights on the sand.

Rowan picked up the short black stick in front of him and squatted on the ground, looking up at the other team members, because the light source was shining on the ground, which made Rowan's face look very terrifying, like the devil who borrowed the corpse to resurrect the soul in the movie.

Luo Wen frowned and said, "Xing Song's words just now reminded me, since we don't know who the people from the Dao are, then we can simply find out their destination, and it may be easier to find clues from the destination." We can make an assumption that if the place where the famous brand exists is the place where the comer will pass, we can get the road map of the comer by connecting all the famous brands we encounter, then the end point of the famous brand is the destination that the comer will reach! And there may be an exit hidden at one end of the route! ”

The others suddenly understood Luo Wen's intentions, and they all came to their senses, bending down and squatting on the ground to look at the temporary sand table. "Zu Long and I saw the name brand for the first time in this T-shaped room, and you are in the opposite direction from us at the beginning, have you seen this kind of name brand in the process?" Rowan raised his head and asked.

"No," Xing Song shook his head and said affirmatively.

Rowan nodded: "The long passage of this T-shaped room should be to the ground, the main entrance of this underground base, but I walked a long way with Zulong and found that the entrance had been sealed, judging from the clues at the scene, it should be the detonator explosives of the engineer Babu, which blew up the entire stairway when the Japanese army evacuated, so it was impossible to go out of the road." But we can set this as the starting point for the time being. ”

Saying that, Rowan drew a T-shape on the sand table, and then began to draw an extension line along the short side of the left side, "And here, I have seen this kind of famous brand here" While saying this, Rowan drew a key number here, and then marked the name tags of himself and Zulong all the way here on the sand table according to his memory, and marked them with circles.

"Here we met the rats, and then the ancestral dragon took me back and took a fork in the road, and here the two of us were besieged by the rats, and the line was broken. Now it's up to you to deduce from the origin."

Luo Wen finished marking and drawing all the famous brands he encountered, and handed the black short stick to Xing Song, who was surprised to find that this thing was actually very weighty when he took the short stick. Xing Song also deduced and drew from the T-shaped room, almost following the route drawn by Rowan, but the disagreement soon appeared.

It turned out that at the staircase on the next floor, Xing Song and the others walked on the right side of the staircase, while Rowan and Zu Long walked on the left side, and then a two-layer plane map of the underground base was gradually presented in front of everyone, and the bloodthirsty face of the underground base was also revealed little by little!
