As soon as this group of Japanese troops was killed, the Japanese troops guarding the back gate pounced. There were about 30 Japanese troops in this force, with two machine guns, two grenadiers, and the rest were all 38 large covers. This Japanese army learned very well. They must have seen the small group of Japanese infantry just now, and the coordinated offensive tactics were shattered in one shot. Naturally, they know that their enemies have powerful weapons and accurate marksmanship. Naturally, I didn't dare to get too close. Just look for cover about 200 meters away and attack on the spot.

Ren Biao looked at the group of Japanese soldiers and shook his head with some regret.

"Holy shit, this time the little devil has learned to be well-behaved, and he will start looking for cover more than two hundred meters. Grandma's! I don't have a chance to do it myself! Don't play with the little devils anymore, start explosives! Under the action of a wolf-toothed warrior, as the detonator was pressed, the electrical signal generated by the electric detonator was instantly transmitted to the electric detonator, and the detonator detonated the explosive package. A total of 20 5-kilogram explosives bags were buried, all of which were concentrated in warehouses, research buildings, supply depots, radio stations, and other very important places. The rest, such as barracks dormitories, were not blown up due to the shortage of explosives packs. But even so, the foundation of the 731st Unit of the Japanese Army, which is notorious in history, has been completely destroyed!

The first thirty-one core researchers, including twenty-seven colonel-level officers, four generals, and important materials and samples were all captured by the Wolf Tooth Special Operations Team led by Tian Zheng. The rest of the Wei-level officers, research equipment, etc., all turned into flames as the explosives exploded. The Japanese army wanted to rebuild a similar institution again, and the effort and money spent were not a small amount. Research into the use of their viruses and bacteria in warfare will also be delayed. These biological and chemical weapons may not be available on the battlefield of the Anti-Japanese War in the future.

Ren Biao took the remaining six wolf-tooth warriors plus the two warriors who returned from Baihualou, a total of ten people. Divided into two troop carriers, one kilometer apart from each other. Begin the retreat along the predetermined route at a speed of about thirty yards.

The Japanese Army's Unit 731 was stationed less than three kilometers away from an infantry brigade of the Japanese Kwantung Army stationed in the Harbin urban area. So in the planned retreat plan. Ren Biao's second group had the task of covering the retreat of the main force and sniping at the pursuing enemy.

Ren Biao deliberately slowed down the speed of the car, just to get rid of the Japanese infantry who were chasing, and let them ride in a part of the troops with the ability to move quickly, such as cars and armored vehicles, to catch up first.

The truth is just as Ren Biao thought. The infantry brigade pursued by the Japanese army saw the rut marks on the ground, and first began to pursue according to the normal marching column. But after twenty minutes, there was still no sign of the second group of wolf teeth. The commander of this infantry brigade of the Japanese army was in a hurry. All troop trucks were ordered to load infantry, and together with the armored vehicles, there were four troop trucks, loaded with a full hundred Japanese infantry. Plus two armoured vehicles with heavy machine guns were organized as advance teams. The captain led the group to catch up first. The infantry in the rear all ran forward, and they must catch up with the large force as soon as possible.

Ren Biao pinched his watch and counted the time. To be honest, this trick was once annotated by Tian Zheng as a classic example in the original special operations textbook. In the attack on Tai'an some time ago, Qin Ming, who was the commander-in-chief of the First Route Army at the time, sent a sharp knife battalion as a bait to lure the snake out of the hole, and then used this tactic of dividing and annihilating it to win a complete victory. At this moment, when Ren Biao really used this tactic, he really realized the horror of this tactic.

Less than an hour. The vehicle's headlight lights have been revealed in the back. Ren Biao saw that the mechanized troops of the Japanese army had caught up. Give the order immediately. All the wolf-toothed warriors in the car jumped out of the car. The drivers of the two cars who were left behind continued to drive the car forward at a normal speed.

The Northeast is mountainous. This is another road to the direction of Tongliao. Not only are the road conditions not very good, but the mountains along the way are steep and steep. The Japanese soldiers in the back also took a fancy to this, and it was expected that the team of wolf teeth would not go far. That's why they boldly divided their troops to pursue.

The Japanese soldiers had bright lights and drove quickly. Ren Biao nodded, a total of four troop carriers and two armored vehicles. Ren Biao made a few gestures. The rest of the wolffang warriors nodded. After the Japanese convoy came, Ren Biao narrowed his eyes. With a wave of his hand. Two rockets hit the two Japanese armored vehicles in unison. Two huge fireballs accompanied by two violent explosions made the Japanese soldiers on the four troop transport trucks all feel cold!

The Japanese soldiers panicked and prepared to get out of the car. But Ren Biao and the others threw the grenade in their hands at the same time that the rocket hit the ground. Seven people, each threw two. All exploded in or near the middle of those four troop carriers! If the wolf-tooth warriors didn't even have this point of accuracy, I'm afraid they would have been returned to the front-line combat units a long time ago! Fourteen grenades exploded at the same time. Immediately, the Japanese soldiers in these four trucks mourned. A third of the Japanese soldiers were killed or wounded! The rest of the Japanese soldiers did not save the wounded Japanese soldiers first, but each looked for cover and began to return fire!

Each of the four Japanese trucks had a light machine gun on it. But in the first battle, two of them were destroyed by grenades. One of the remaining two was crushed under the body of a Japanese soldier who had been killed, and at the moment it was suppressed by the vitality of the wolf's tooth eight-bar automatic rifle, and no one could rush to take it down. As soon as the only remaining machine gun fired, it was immediately hit by a single headshot from the wolf-toothed warrior who had been prepared for a long time! Although the other Japanese soldiers were shocked, they still rushed forward, trying to control the machine guns and win back the initiative on the battlefield. Obviously, however, this is unrealistic. In addition to the non-stop energetic rotation of the wolf-tooth soldiers, the fighters who were specifically responsible for keeping an eye on the outcropping soldiers of the Japanese army were fired one by one. It wasn't until seven or eight Japanese soldiers had been killed that the Japanese soldiers realized that the machine gun was a grim reaper. Whoever touches it dies! Although it is said that if you can't get the machine gun back, it is very likely that you will be defeated and die, but that is only a possibility! If anyone grabs the machine gun now, it will be obvious that they will be killed immediately!

Ren Biao made a few more gestures. Four wolf-tooth fighters were in charge of suppressing the fire on the spot, while the rest made a detour to the side and began a roll call of the Japanese soldiers hiding under the makeshift bunkers! The battle lasted about fifteen minutes. This group of Japanese advance troops was completely destroyed. Ren Biao kicked the captain of the Japanese army who was shot in the chest and died in the passenger cab, and after taking off the opponent's rank, he began to clean the battlefield and set traps.

Twenty minutes later, Ren Biao looked at the soldiers in front of him who had finished replenishing their weapons and ammunition, as well as the trap set by him himself, and a playful smile appeared on the corner of his mouth.

"Let's go!" Ren Biao smiled heartily. It feels really cool to fight such a battle, and it is hearty!

The part of the Japanese infantry that came after them was really desperately chasing. It was an hour's drive, though only thirty yards, and the mountain roads were rough, probably only a little over twenty yards. But for such a long distance, the normal running march of the army took about three hours. The Japanese infantry who were pursuing from behind arrived in less than two hours! However, at this time, Tian Zheng and Ren Biao had already converged, and they walked a long way towards the way they came.

The part of the infantry that the Japanese pursued was led by a captain. Along the way, he kept urging to hurry up and hurry up! There were four cars and two armored cars in front, and he knew how powerful the firepower was. Huaxia's troops don't have a lot of cars, so if the infantry he leads goes slowly, all the credit may be taken by the cars and armored vehicles in front! The Japanese captain hurried to the place in a hurry. But what he saw was a big surprise to him!

The two armored vehicles had long been burned to the ground and could not be seen in shape. It can only be distinguished from the pile of blackened scrap iron that this is an armored car. The other four cars were also covered in bruises and riddled with bullet holes. These were enough to surprise him. But these were far less shocking than the corpses of Japanese soldiers all over the ground! A hundred infantry soldiers! Plus two armored vehicles, and that's it! The Japanese captain searched and finally found the body of the captain. The soldiers who searched the battlefield in a circle also returned. Seeing the captain's probing eyes, they all shook their heads. A circle of backbone-level Japanese commanders all formed a circle.

The Japanese captain said bitterly, "Captain, Captain, his jade is broken!" As he spoke, he shed a few tears that looked like pain.

The rest of the Japanese army also choked up very cooperatively.

I cried for a while. The Japanese captain wiped the tears from his face and said, "Now the captain is also broken." The officers and men of the whole brigade obeyed the order! Before the arrival of the new appointments, I will command the troops! Those hateful enemies! We must go to the dead captains and warriors to take revenge! ”

"Revenge!"

I have to say that this Japanese captain knows how to play with people's hearts. This shout immediately brought together many officers and soldiers.

"Captain, please rest in peace! We will surely avenge you! The Japanese captain said as he tried to pick up the body of the dead Japanese captain.

His tearful eyes, which were performing affectionately, did not even notice a thin thread pressed under the corpse of the Japanese captain. With a "click" sound, a grenade exploded! This Japanese captain and a circle of Japanese backbones all followed their captain! And that's not all. With the explosion of this grenade, circles of fire suddenly burned around it. It was the oil in the fuel tank of the car released by Ren Biao, and it was connected to the gas outlet of the fuel tank with a rope made of torn Japanese soldiers' clothes. In this way, the gasoline does not evaporate quickly. And to go will soak these clothes on top of the rope they are made of. At this moment, it was ignited by a grenade, and immediately the gas burst into flames, and then the fuel tank was detonated! Four trucks were set on fire, and all the Japanese soldiers in the vicinity of the four trucks were killed! (To be continued......)
