Entering the door, a long corridor identical to the other side appeared in front of the two of them, but the room on this side was no longer an iron door, but a wooden door, and most of the door panels were badly damaged, and they were weak to stick to their posts.

Rowan entered the first room and looked, this room used to be an office, the mahogany tables and chairs were crooked, a small number of scattered animal bones could be found on the ground, there was a deer carcass that had not completely decomposed, swarms of maggots were drilling in and out of it, the blood stains on the ground had solidified, and the parts of the ground were frozen at low temperatures, and they were full of beast footprints.

Rowan and Zu Long couldn't help but raise their vigilance, carefully searching room by room, but they found nothing of value, and walked all the way to the end of the corridor, where they could only find Japanese documents with the occasional Chinese characters.

In these documents, Rowan can often see "secrets", "failures" and "trial works", and can vaguely guess that this should be an experimental base of Unit 731, and everything where it is located is top secret, and there are many failures.

In view of this, Luo Wen and Zu Long did not stop, and these things were left to the technical department to study, and in their eyes, this was the book of heaven.

The two turned around and walked all the way, and occasionally they could see a name sign with "Kwantung Army Epidemic Prevention and Water Supply Headquarters", but there were no rooms on both sides, and there were convex cement walls. After that, I went around this underground base to search for Yin Beasts, and I also had a deeper understanding of this underground base, and occasionally I could see a few iron doors, but either the iron doors were rusty and could not be opened, or I entered some rooms with strange instruments, but I didn't understand why.

Zu Long has been practicing acrobatic jiu-jitsu since he was a child, so he must strictly control his weight, so that his dexterity and agility are exchanged for the defect of physical endurance, continuous fighting and searching consumed a lot of his physical strength, until he felt fatigue rising before signaling Rowan to rest, Rowan looked around, and only then found a corner where he could look at each other for a short time. Zu Long squatted on the ground and rested for a while, then looked up at Luo Wen: "What do you think?" ”

Rowan was taken aback by his question, then rubbed the tense muscles between his eyebrows and leaned against the wall and replied, "It's a bit abnormal here, some things can't be figured out." ”

Zu Long smiled and leaned closer to Luo Wen: "Tell me about it"

Luo Wen Yile: "Zu Shao, Zu Shao!" In addition to the sea in our team, you have a small brain capacity, and I'm afraid that if you talk too much, your brain will flow out of your ears and eyes! ”

Zu Long was stunned: "You are too good at squeezing people!" ”

Luo Wen squatted down and patted Zu Long on the shoulder with a wicked smile and said, "Young Master Zu, if you tell me where you hid all the flying knives, I will tell you what I think."

Zu Long moved his body to the side, turned his head, and said impatiently, "I won't ask."

"Don't be so conservative, your outfit is the same as mine, there is no secret door at all, I've been curious about this for several years"

Zu Long turned around and scolded with a smile: "Captain Luo, sooner or later you will die from your curiosity"

Rowan took out his cigarette and thought about it and stuffed it back into his pocket, then patted Zu Long and got up and said, "I know the way, but if there is anything I don't know, it is more uncomfortable than death." Let's go. ”

Zu Long sighed before continuing to walk, at this time the two of them passed through a wide corridor and came to a huge dilapidated iron gate, which seemed to have been hit by a truck, and it was very twisted, but it made Rowan suddenly have a bad premonition.

He carefully inspected the iron door by the light of the shoulder lamp, but the rust was so bad that he couldn't tell anything, so Luo Wen and Zu Long had no choice but to continue exploring inside.

The footsteps of the two people are extraordinarily loud in this underground corridor, and occasionally the sound of water droplets falling into the water can be heard, in this dark underground, time seems to have no meaning, Zu Long dragged his legs and complained in his heart, a negative emotion is slowly rising, this monotonous hike does not know how long the road will go, obviously this feeling is easy to make people irritable and annoyed.

But after walking far, rooms began to appear on both sides again, but the door of this room was not made of wood or iron, but of fine white steel! It is still very well preserved in this humid environment at a depth of 100 meters.

Rowan and Zu Long glanced at each other, leaning on the nearest one on guard. This door is also a slide-like sliding door, which needs to be pulled horizontally to open, but it is not only the material that is different from other iron doors, but even the door lock has become a hidden lock, which also surprised the two.

Zu Long didn't have much effort to open the door lock with a homemade master key, as Zu Long carefully turned the keyhole, there was a soft click, and then a series of mechanical sounds came from the door, Rowan quickly took out his pistol and opened the firing pin to prevent accidents, and Zu Long also conjured a lancet to be vigilant.

Suddenly, a loud exhaust sound was heard coming from inside the door, and the dust at the bottom of the steel door was cramped into the door, which surprised both Rowan and Zu Long, because there was a vacuum in this room!

In that era, this must be said to be a big deal, Rowan carefully opened the door a small crack, Zu Long lightly lit a cold firework and threw it in, the two leaned against the wall, through the light of the cold fireworks to look at the situation in the house, after a short pause to confirm safety, Rowan wasted a lot of strength to open the door a large crack, and the two were able to step into the house.

This room should be an operating room, at first glance you can see an operating table under the old shadowless lamp, surrounded by all kinds of instruments, some of them are famous, some have never seen them at all, all around are all kinds of medical cabinets, which are full of used protective clothing and gloves, there are several small oxygen cylinders piled up in the corner, and there are two large medical oxygen cylinders next to them, and there are also a few sealed protective clothing scattered at the door under the feet.

After a brief inspection of the room, Rowan couldn't help frowning, Zu Long squatted on the ground and looked up at Rowan with a smile and asked, "Wen'er, don't you think there is something wrong with this operating room?" ”

Luo Wen looked at Zu Long, and said with a rare smile: "Heh! Did Master Zu make a discovery? ”

Zu Long was a little embarrassed, scratched his head and said, "I've been with you for a long time, and I've learned a little bit about it." At first glance, this room is no different from an ordinary operating room, but an operating room is actually vacuum, according to you, can we deduce that the operation in this operating room must be carried out under a vacuum? The oxygen cylinders and protective clothing in the room were obviously for the surgeon, and the large medical oxygen cylinder was for the person being operated. But what surgery is needed? And, I found a suspicious point. ”

Rowan took out a cigarette and put it in his mouth, thought about it but didn't light it, held the cigarette in his hand and sniffed it in front of his nose, and looked at Zu Long to signal him not to sell it.

Zu Long pursed his lips: "I guess you noticed before me that there were no scalpels, hemostats, medical alcohol, medicinal cotton, infusion stands, or even any medicines in this operating room, which has to be said to be very abnormal." ”

Rowan nodded, put the cigarette back into the cigarette case, and said: "Yes, according to your train of thought, this operating room is obviously a vacuum operation environment carefully designed and built by the Japanese, this kind of operating room can be described as a high standard in that era, and even now this kind of operating room is not common." It stands to reason that the biggest advantage of the vacuum operating room is to minimize the chance of infection after surgery, and if you can use this standard operating room to operate, then the patient who is operated on should be an extremely important person, and his life must not be missed. However, there are no surgical tools, and it seems that there is no need to do surgical infusions, or even medicines, which is really doubtful. ”

The two of them thought in silence for a while, and found that there was no reasonable explanation, so it was better not to want to, so they decided to move on.

The three consecutive steel doors inside were all vacuum operating rooms concocted in the same way, which deepened the surprise of Rowan and the others, it seemed that the water in this underground secret base of Unit 731 was deeper than they thought.

Then two forks in the left and right began to appear inside, both of which were stairs down to Lu, which really made the two of them feel even more confused. This underground base can no longer be described as an ordinary large-scale pen, in that historical era, the shortage of military spending was a problem that every belligerent country had to face, but this underground base still has such abundant financial resources to support the construction of a two-story underground building, which is too puzzling.

The two of them went down the stairs on the left, and what appeared in front of them was a spacious corridor, and behind them was an open huge iron door, Luo Wen's curiosity was infinitely amplified at this time, and tension and excitement were intertwined, what was in the second underground floor?

As soon as I entered the corridor on this floor, I found that there were dense iron doors on the left and right, and these iron doors all had observation openings, but the rusted iron doors and observation ports made Rowan and Zu Long unable to know what was inside the road. The gray-white ground was coagulated with large pools of blood, and there were traces of dragging, because there was no stagnant water in this layer, so the frozen blood was particularly dazzling.

Rowan lowered his body, trying to identify the footprints with clues from the bloodstains, but it was only filled with a large number of animal footprints, which may have been left by the Yin Beast, or it may have been a wild animal such as the unlucky fawn that had broken in by mistake, and the footprints were very messy, and the age made it really difficult to identify them.

After walking about a few dozen meters inside, Rowan suddenly found that one of the observation openings was actually open! Rowan leaned sideways close to the iron door and leaned against the wall to look inside. Only for a moment! Rowan felt his blood surge, his eyes reddened, and his head buzzed like boiling water! It's as if there are thousands of troops galloping desperately in my head!

After a long while, he took off his glasses, closed his eyes and calmed down, and then without saying a word, he continued to walk inside without looking back.

Zu Long has never seen Luo Wen have such a gaffe in the team with Luo Wen in the past few years, in his heart, Luo Wen is a little old man who is not smiling, strict and serious, and his mood is invisible, but this sudden change surprised Zu Long. Zu Long hurriedly rushed to the observation port, turned on his shoulder lamp and looked in, and in an instant, his expression was the same as Luo Wen's!

Through the observation port, the first thing that catches the eye in this small room is Sen Sen's white bones, and from the observation port alone, there are no less than twenty bodies, all of which are in tatters, and there are still large blood stains on them, judging from the style, there should be men and women.

What attracts attention is that more than a dozen of them are sitting against the wall, shoulder to shoulder, hand in hand, and on the gray cement wall behind them, a clear line of blood books stung Zulong's eyes: Down with the Japanese invaders, long live the Chinese people!

Zu Long's throat and eyes seemed to be blocked by something, he couldn't spit it out, he couldn't swallow it, his eyes were hot and painful, his nostrils were swollen because of wheezing, and his two fists clenched unconsciously!

Zu Long unconsciously looked back at the road he came, and then looked at the other side, this densely packed dozens of rooms turned out to be prisons, imprisoning iron-clad Chinese compatriots! Zu Long gritted his teeth, as if he wanted to hold back something, and then calmed his breath a few times before he raised his steps and continued to move forward with Rowan, but his steps were as heavy as Rowan's.

The corridor was about to come to an end, but the two of them, who were in a heavy mood at the moment, suddenly made a discovery, and immediately turned into the penultimate room in the corner, and the door seemed to be open!

Rowan hesitated before flipping the pistol wheel and walking forward, and Zu Long followed the humming of the Ring Moon Knife at his fingertips. But unexpectedly, when I got closer, I found that it was not an open door at all, but the whole door was knocked out of the room from the inside to the outside by a huge amount of force, and the horror of this force made the iron door be fiercely embedded in the cement wall opposite the door!

This discovery is obviously not something to be thankful for, and it is not a joke to have something of this strength if you are unlucky. Zu Long turned on the shoulder lamp and cautiously looked into the room with Luo Wen.

There was nothing in the room, an iron basin was placed on the empty ground, it seemed that the basin was frozen with the ground, Rowan squatted next to the basin and touched it with his hand, and sniffed it under his nose.

"It should be human blood." Rowan stood up and looked at the room and said.

"Human blood?" Zu Long squatted on the ground and looked at it, "What do you mean?" The Japanese drank human blood from those imprisoned here? ”

Rowan shook his head, pointed to a large black thing in the corner and said, "There are not only people imprisoned here, there should be some animals, this should be the feces of that animal." ”

Zu Long walked over with some disapproval, frowning and fiddling with the lump of feces with a lancet, but what he didn't expect was that in a few moments, Zu Long took out a piece of something from it.

Rowan hurriedly looked through the light of the lamp on his shoulder, but the two of them clearly saw that it was clearly the finger bone of a human index finger!
