The Kwantung Army's epidemic prevention and water supply headquarters, the name of this unit seems to be ear-catching, literally a logistics department to ensure the safety of drinking water, but he also has a notorious name known as the devil: Manchurian Unit 731.

Manchuria Unit 731 is referred to as Unit 731. It is the code name of the bacteriological warfare agent factory of the Japanese invading army. In order to cover people's eyes, they successively called the "Kamo Troops", "Dongxiang Troops", and "Kwantung Army Epidemic Prevention and Water Supply Headquarters".

Unit 731 was a secret military medical unit engaged in biological warfare bacteriological warfare research and human testing during the Japanese invasion of China. Unit 731 disguised itself as a water purification unit and built its base in Harbin, northeast China, with a large bacteriological factory covering an area of 300 acres.

It is under the dual leadership of the Japanese Ministry of Army, the General Staff Headquarters of the Japanese Army, and the Headquarters of the Japanese Kwantung Army, and is divided into eight departments and four detachments, with a clear division of labor and each fulfilling its own responsibilities, and is set up for bacteriological research, bacteriological experiments, bacteriological weapons manufacturing, and bacteriological production. Unit 731's atrocities against the Chinese people were simply horrific, using bacteria, viruses, frostbite and cruel means to carry out a large number of live experiments on the Chinese people, during the formal establishment of Unit 731 into the northeast, to the defeat and withdrawal after the most outbreak, about 10,000 Chinese compatriots were taken precious lives.

Unit 731 was rigorous and brutal, and when it was defeated and withdrawn from China, it burned a large number of materials and instruments that could not be taken away, including those who were still imprisoned and did not conduct live experiments, and buried them alive or burned to death, trying not to leave any evidence of the crime. And the direct leader of this demon force is Shiro Ishii, who is full of evil.

In Luo Wen's memory, the site of Unit 731 should be in the suburbs not far from Harbin, but how can the name plate of Unit 731 appear here?

During the Japanese invasion of China, Unit 731 did have several branch strongholds in the whole northeast, especially Heilongjiang, but they should all be in Heihe and Mudanjiang, which are close to the national border.

And I have never heard that there is a secret base here, including the later collection of relevant documents and materials did not mention it, such a large amount of money invested in the construction of such an underground base, and hidden so deeply, it seems that there must be a huge secret hidden in it.

Rowan took out his mobile phone to take pictures of the hall, furnishings and brand-name information, and then walked with Rowan to the main entrance on the left, out of the gate of this entrance, it was a staircase to the top, just the width of the three people side by side, the height of the roof to the ground was not high, the two went all the way, walked for about five minutes and suddenly found that there was no road ahead.

The staircase under the feet of the two people collapsed here, and the entire staircase was blocked by more than a dozen boulders, from the perspective of the shape of the stone and the collapse, it should be that the Japanese army used explosives to blow up the stairway and seal the exit when they evacuated.

It seems that the Japanese army has no intention of coming back at all, and Rowan speculates that there may be explosives from professional sapper Babu, and several detonators are planted every ten meters, which collapses the entire staircase, so that it is impossible to get out of this road.

Rowan and Zulong had no choice but to return the same way, but when the two of them stepped back into the hall again, Rowan suddenly pressed on Zulong's chest and fixed Zulong in place! Finger to the Ancestral Dragon's clothes, so that the Ancestral Dragon quickly squatted down, and the Ancestral Dragon suddenly realized that there was a situation, and conjured two palm-sized discs in his hands and began to guard the surroundings.

The disc was made of steel, somewhat similar to a disc, but the inner circle was hollow enough for the ancestral dragon to hold in his hand, and the outer ring of the disc was all bladed. Zu Long followed Luo Wen's gaze, and he didn't know when the iron gate that the two of them squeezed in after killing the Yin Beast just now actually opened!

This sudden situation surprised Rowan and Zu Long, and the two stayed motionless in place, when a sound of tearing flesh suddenly came from behind the door that had just been opened!

Rowan hurriedly took off the shoulder lamp and gently stood in the center of the hall directly on the ceiling, the strong light of the shoulder lamp hit the ceiling, and under the effect of diffuse reflection, he could basically see every corner of the room. Then Rowan gently flicked the pistol firing pin away, motioning for Zu Long to turn off his shoulder lamp, and the two of them stood close to the iron door that had just been pushed open, looking out.

At this time, an amazing scene appeared in front of the two!

Two pig-like Yin Beasts were eating the corpse of the deer just now, they were tearing frantically, shaking their heads from side to side to tear off the venison and chew it, but the Yin Beast with too much strength actually threw the deer corpse to the left and right, and occasionally made aggressive warning noises to each other because of tearing the same piece of venison.

Just like to confirm Luo Wen's speculation just now, the two Yin Beasts seemed to arrive as promised, and Rowan calculated that if he attacked the Yin Beast head-on in this narrow corridor, the chance of being counterattacked would be very high, and it was very likely to be injured, so Rowan decided that he had to wait for the Yin Beast Hall before he could make a move.

After Luo Wen and Zu Long retreated to the door of the main entrance, they patiently waited for the two Yin Beasts to be full of wine and food, and the time passed little by little, and after about ten minutes, a Yin Beast slowly came out of the iron door. This yin beast is supposed to have been mutated from a wild boar, with two long fangs almost above the top of its head, and a little minced flesh hanging on it, and its body is covered with rotting flesh and bulging lumps, but it is covered with black hard thorns, and its two front paws are somewhat similar to those of a feline.

As soon as the yin beast entered the hall, it was attracted by the heat released by the shoulder lamp, and because it couldn't see, it kept sniffing with those two huge nostrils.

As the yin beast sniffed, it suddenly seemed to be hit by something, and then one of its heels fell to the ground, and then another yin beast similar to it appeared from behind it, except that this yin beast gave birth to a pair of bird wings.

Maybe because the wild boar was a quick temper when it was born, so now it has changed the temper of the yin beast and is also very short-tempered, this yin beast may just think that the cat's claw yin beast is its way, and in a fit of anger, the cat's claw yin beast will be turned to the ground.

The two yin beasts fought each other together without warning, a bit like a battle between two males during courtship, the originally abrupt shoulder lamp was also left behind by the cat's claw yin beast, just biting, each other used the fangs of more than one meter long to constantly attack each other, the fangs of the two yin beasts were like swords to assassinate and defend each other, there was no win or loss between them, only life and death.

Pulling away from each other, and then running desperately towards each other, the two fangs stabbed at each other mercilessly like spears in the hands of cavalrymen, and one block was followed by the beginning of another charge, and their mouths emitted a strange cry of "whoop".

In just three encounters, the winged Yin Beast was scraped by the black thorns on the cat's claw Yin Beast's body, and the fishy smell filled the entire hall, and it kept scraping the ground with its front paws in anger, and the dust on the concrete floor was rolled up in bursts.

Suddenly, it jerked its head down, and its two fangs aimed straight at the neck of the cat-clawed yin-beast, and it rushed towards the cat-clawed yin-beast like a cannonball. Not to be outdone, the cat's claw yin beast showed its sharp nails on its front paws, and its hind limbs kicked the ground violently and rushed towards the opponent, Rowan could see that this should be the last fight of the two yin beasts, and the ancestral dragon's moon knife rotated rapidly at the fingertips, and was also ready to attack.

When it was too late, I saw that the cat-clawed yin beast suddenly jumped up, and its two front paws actually stepped on the opponent's fangs fiercely, and suddenly pushed the winged yin beast to the ground, making a loud noise. Before the winged Yin Beast could react, the two fangs of the cat's claw Yin Beast stabbed into the neck of the winged Yin Beast, and then picked it hard, and the neck of the winged Yin Beast was broken in an instant, and its head flew out like a football, and the blood on its neck burst out instantly, like a water balloon that had been stepped on, and blood splashed everywhere!

This time it actually provoked the cat's claw yin beast to hold its head high and howl excitedly, but Rowan and Zulong both knew that the opportunity had come!

The ancestral dragon was the first to attack, and the Ring Moon Knife that flew around his fingertips was thrown out in an instant, and the ultra-thin blade flew like a disc, drawing a strange arc straight towards the fangs of the cat's claw yin beast. From right to left, the Ring Moon Knife first cut off the left fang of the cat's claw yin beast, and then only caused a wound to the right fang due to exhaustion, but it still slammed into the fang to the middle.

At the same time, Rowan fired three shots in a row, aiming at the head of the Yin Beast, but due to the first shot, the Cat's Claw Yin Beast was shot backwards, and the last two shots were all hit on the wall, and the cement wall was instantly blasted open two craters.

The cat's claw yin beast was knocked into the wall and hit the ground, and the entire parietal bone of the head was lifted open by Rowan's bullet, revealing a blood-red brain, but it immediately turned over and rushed towards Rowan, and Rowan fired three shots in a row and all aimed at the head of the yin beast, but except for the first shot that just broke the fangs of the cat's claw yin beast inserted in the moon knife, the other two shots only hit the cat's claw yin beast's body, bringing up a piece of flesh and pus, revealing Sensen's white bones!

In the face of the cat's claw yin beast that was rushing forward, Rowan jumped to avoid the attack, turned around and raised his hand and hit the buttocks of the cat's claw yin beast again, and suddenly the entire buttocks and tail of the cat's claw yin beast were instantly knocked away, because the cat's claw yin beast was still in the inertia of sprinting forward at this time, suddenly the buttocks were shot from the side, and its whole body was brought up in the air and turned over, and fell to the ground.

Zu Long seized the opportunity, and the two Ring Moon Knives flew in an arc towards the two front paws of the cat's claw yin beast, and the two front claws were cut off from the position of the knee joint at the top of the knee, and the two blood lines sprayed at once!

Rowan had just stood firm at this time, but he knew that the Dao Machine was no longer coming, so he ran towards the cat's claw yin beast on his toes little by little, and before the cat's claw yin beast had time to get up, its head was shattered by Luo Wen's shot, and the flesh and blood mixed with the brains splashed all over the ground!

Rowan held up his gun and looked at it for a while, relieved to make sure that the cat's claw yin beast was dead.

Zu Long looked at the winged Yin Beast's head, which was still making a "hum" sound at the moment, but it had obviously lost its ability to attack, so he walked to the ground and picked up the Ring Moon Knife that he had just thrown out.

"This thing's teeth are so hard"

Zu Long took the Ring Moon Knife that had just cut into the cat's claw Yin Beast's fangs and swung at Luo Wen, the outer blade of the Ring Moon Knife made of stainless steel had basically been worn out at this moment, and all he got was an extremely small gap.

Rowan pushed the wheel to help cool down the gun, the green smoke in the barrel of the gun carried a strong smell of gunpowder, this pungent smell of gunpowder made Rowan feel steady, but he also realized another problem, that is, in the underground where the ventilation system was operating normally, this smell had a lot of attraction to the Yin beasts that preyed on by smell and temperature, so it was not suitable to stay here for a long time.

Rowan picked up the shoulder lamp from the ground, it was covered with blood and minced meat, then looked around, walked to the side of the Japanese flag and pulled it hard, tearing off the big fiery sun, and then wiped the shoulder lamp inside and out.

Rowan estimated the illumination time of the headlamp on his shoulder, asked Zu Long to turn off his lamp, leaving only his own lamp, and then walked in along the exit on the left side of the T-shape.
