Although Myitkyina has been completely controlled by the various departments of the expeditionary force, the city is mixed, with the two integrated divisions of the 22nd and 38th Army stationed in India, the 2nd Army of the 72nd Army of Yu Xiaoqing's East Road, and the three main regiments of Liao Mingyu's Honorary Third Division...

Although several troops are of the same clan, they are not of the same genus, and they are not very familiar with each other, and they are all victorious divisions, and they are inevitably a little arrogant and impetuous, and they feel that they are the best if they don't sound good.

In order not to cause conflict, they tacitly divided into three areas, which are clearly separated from each other, and they only clean the battlefield within their own control area, which is less close but can also avoid some unnecessary trouble.

"Give Lao Tzu a little more care, I don't believe it, there is not a single fucking big fish."

Hong Mu sat angrily on the armored car, and his three regiment assault battalions were searching everywhere in the city, even the corpses on the ground, in order to find those high-ranking Japanese officers.

Some of the captives were caught, but they were basically small fish and shrimp, and there were few with flowers on their collars, and I didn't know where the commanders of those divisions and regiments had died, and I didn't even see a corpse.

"Battalion commander! Battalion commander! ”

At this moment, a soldier jumped out of the crowd and shouted excitedly: "Battalion commander, there is a tunnel in front, do you want to go and take a look?" ”

"Where? Take me there! Hong Mu suddenly came to his senses, turned over and jumped out of the armored car, and directly told him that there must be a harvest inside.

Following the soldiers to the front, here was a battery shattered by shells, and below there was an entrance more than a man wide, which had been buried by rubble earlier, and if the soldiers had not rummaged carefully, they might not have found it.

For the sake of safety, Hong Mu ordered a squad of soldiers to go down to explore the road first, and only after making sure that there were no enemies did he take people in.

Climbing down the iron ladder, the cold and damp breath came to the face, the tunnel was extremely dark, and the air was not very circulating, and it made people feel uncomfortable and stuffy when they entered it.

The soldiers were holding rifles, and the soldiers in the front row were using flashlights to light the way, carefully groping their way forward, the tunnel was not wide but very deep, and there was an iron ladder exit straight up and down every other section, which should be the location of the various fire fortresses of the Japanese army.

The group slowly moved forward, and sure enough, they found a Japanese headquarters in the depths of the tunnel, with telephones and radio stations, and a plaster flag hanging on the wall, but unfortunately most of the documents and equipment had been destroyed.

"Grandma's, the little devils are all playing collective suicide here."

Hong Mu turned on the flashlight, and all he saw were the corpses of various Japanese soldiers, who fell to the ground horizontally, all of them ended their lives with the weapons in their hands.

Among them was the corpse of an officer who was kneeling on the ground with a short knife stuck in his stomach, but his head was gone, presumably by the so-called wrong man.

"Dog, if you stab yourself and have your head cut off, what kind of fucking bullshit logic is this?" Hong Mu frowned in displeasure and kicked it over, the smell of blood in the room made him sick.

It's so cruel to oneself, and it's conceivable to others, and only the Japanese who are perverted to the extreme would do this kind of thing.

Everyone searched for a lot of documents from the corpse, this should be the central headquarters of the Japanese, and the guy who committed suicide was the commander of the city defense, Kiyozaburo Okazaki.

Although the largest officer of the Japanese army in Myitkyina became a corpse, these things in his hand were enough to prove his identity, and there were several adjutants in the house, and this net could catch a lot of big fish.

"Battalion commander! There's a situation here! ”

Suddenly there was a soldier's shout in front of him, Hong Mu's eyes froze, and he strode over with a gun.

The group was led by the soldier all the way forward, and after several large bends in the dim light, a large two-meter-high iron gate finally appeared at the end of the tunnel, which was in stark contrast to the low passage, and several soldiers were nervously looking inward.

Seeing the large army coming, this group of vanguard soldiers gradually gained confidence, and slowly opened the door under the signal of Hong Mu's eyes, and several bold guys immediately grabbed their weapons and rushed in.

There is a hole inside the iron gate, the space inside is huge, divided into several rooms, and there are many bottles and cans piled up in the corner, like a secret room, a large number of Japanese logos and skulls printed on the wall, it is enough to see that this place is not simple.

"What the hell is this?" Hong Mu looked around vigilantly, Japanese could not be understood, and could only vaguely identify a few words similar to Chinese.

"The Southern Army's epidemic prevention... Ministry of Water Supply, 9420? ”

At this time, a pile of gas masks on the ground suddenly attracted his attention, and then thought of those skull logos, and his heart instantly struck a thrill:

"... I'm afraid this is a little devil's biochemical laboratory, right!? ”

The surrounding soldiers were also taken aback, if you want to say that the most terrifying unit of the little devil must definitely belong to this group of crazy animals.

Although the 9420 Epidemic Prevention and Water Supply Department is not as famous as Unit 731 in the north, as the only biochemical unit of the Japanese army that has been active in Southeast Asia, they are also notorious, and the expeditionary force has suffered a lot of losses in front of this force.

In the recent battle to defend Mangshi, the 18th Division used a large number of poison gas bombs, including the Gangzi 9420 unit, which also caused indelible damage to many soldiers of the third regiment.

When Zhong Bin led his team to cross the river for the first time to counterattack Longling, he was also attacked by a batch of bacteriological bombs, and more than 5,000 soldiers were infected with the plague and lost their combat effectiveness.

Hong Mu touched his cheek unconsciously, the touch of the pitted snakes and pythons made him angry, he was disfigured by the mustard gas of the little devil in Mangshi, and he still feels a faint pain.

The iron gates are like black holes that devour people, he knows very well, but wherever the words are stained with biochemical poison gas, they should not be underestimated, and it is best not to try to touch these things easily without strict protection.

"Stay vigilant, don't touch things, you two go and inform Junzuo, and the others will exit the secret room the same way."

"Yes!"

……

The news that the assault battalion had discovered the laboratory of the Japanese biochemical troops quickly reached Liao Mingyu's ears, and the pot exploded at this moment, and the latter did not dare to block the entire area in a hurry, and only after making sure that the situation was completely under control did he send people down to the tunnel to carefully investigate the situation.

In order to have an accident, all the soldiers who went down again put on gas masks and chemical protective suits, fortunately, the third division has always attached importance to the protection of biological and chemical weapons, and Liao Mingyu usually exchanged chemical protection equipment from the system, at least in the face of this situation, he can still handle it.

At this moment, there is no trace of the Japanese in the secret room, and there are very few useful things in it, except for some bits and pieces that are too late to take away, most of the equipment has been destroyed and destroyed, only some experimental equipment and daily necessities are left at the scene, and there are some traces of the experimenters...

According to the soldiers' investigations, it is very likely that the Japanese biochemical troops fled Myitkyina with materials and important items before it was besieged......
