Fifteen minutes later, Lei Yunfeng led the brothers of the special operations team to finally come to a dense wood, when they found that an area of more than 300 square meters of open space, there was a courtyard, and the open space illuminated by two dim lights outside the gate was eerie.

The courtyard was closed by two thick iron gates, and four armed gendarmes stood at the door, staring nervously at the surroundings.

They trembled with vigilance at the sound of fierce gunfire from outside the mountain, and they didn't know if they were safe here, so they stood at the gate with guns on guard.

Lei Yunfeng said in a low voice: "If we want to enter the compound smoothly, we must first deal with these four gendarmes, I order, each of the four of us locks up a little devil, and we must make a lethal move when we act, and we must not delay time to cause a shootout, action." ”

The four black shadows moved quickly in the dense forest, and soon divided into groups of two and approached the gate of the compound.

When the two groups of personnel arrived at the pre-designated place and observed that they were still more than a dozen steps away from the gate, as long as they suddenly launched a sneak attack on the four gendarmes standing guard, under the enemy's unsuspecting situation, it would not be difficult for them to be fatal to Lei Yunfeng.

Lei Yunfeng gently pulled Su Xiaoyan beside him and asked, "Ah Yan, can you deal with a little devil alone?" ”

"Don't worry, cloud shopkeeper, I will never be ambiguous if you can do it." Su Xiaoyan said with her upper and lower teeth bumping because she was nervous.

Waiting for Lei Yunfeng to issue an action order, the brothers of the special operations team who rushed out of the woods in an instant, not to mention Su Xiaoyan's nervous teeth at this time, even the anti-Japanese heroes Fang Shichao and Wang Liang, who were on the battlefield of killing the enemy, were short of breath due to nervousness.

Just when everyone was about to get ready to go, suddenly a Japanese patrol came out of the woods and greeted the four military policemen standing guard: "Oh, did you find anything suspicious?" ”

"No, you didn't find it." Hearing the fierce gunfire coming from outside the mountain, the four gendarmes continued to ask uneasily: "Why is there a fierce gunfight outside, and who is the person who appeared on the outskirts of Yuanping Mountain?" ”

"A group of anti-Japanese elements who don't know whether they are alive or dead, just five or six people want to infiltrate the important base of our Imperial Japanese Army and destroy it, and at this time they have been surrounded by the special special task force, and it should not take long to wipe them out."

The Japanese patrol spoke a few words to the sentry at the gate, then turned and entered the dense woods, and the courtyard soon fell silent inside and outside the gate.

Lei Yunfeng heard that the patrol team said that the special high class special task force was ambushed at the foot of Yuanping Mountain in advance, and at this time it was engaged in a fierce battle with Hou Sheng and others who had penetrated into the encirclement of the Japanese army, and he couldn't help but worry about the lives of these brothers.

Fortunately, the underground party deployed a New Fourth Army commando team in advance and hid it around the foot of Yuanping Mountain, and at this time, such a fierce gunfire could not be caused by just five or six people waiting for life.

It must be the New Fourth Army commando, in order to rescue the waiting students and others, they launched a fierce gun battle with the special high class special team on the periphery to cover the waiting students and them to break through.

In order to seize this opportunity that was about to be lost, Lei Yunfeng decisively issued an action gesture to Fang Shichao and Wang Liang in the other group.

At the moment when Lei Yunfeng issued the order to act, four black shadows pounced on the sentinels at the door from both sides of the gate, and before the four sentries could react, they were killed by a knife.

Lei Yunfeng ordered to immediately change into the uniform of the Japanese sentry, and quickly dragged the four corpses away and hidden.

He found that there were two thick gates in the courtyard, one of which left a small door to enter and exit, Lei Yunfeng gently pushed it and did not push it open, not only did he push it hard again but he did not push it open.

This shows that this small door is tied from the inside, is there still a sentry standing guard inside, or is the sentry standing guard outside the door not qualified to enter this mysterious courtyard at all?

Due to the urgency of time, Lei Yunfeng did not allow him to analyze carefully, and if he wanted to destroy the Japanese army's bacteriological weapons base, he had to enter the courtyard in the shortest possible time.

He didn't know if there were still light and dark sentinels in the courtyard, and if they recklessly climbed over the wall and alarmed the light and dark sentinels inside, then their operation would fail. At this time, the only way to ensure the successful completion of the mission is to secretly infiltrate the core research laboratory of the Japanese army.

The three brothers standing beside them, seeing Lei Yunfeng standing outside the door and not taking action, not only asked in a low voice, "Boss Yun, how do we enter the compound?" ”

"Throw stones and ask for directions." Lei Yunfeng said as he picked up a stone in front of his heel, raised his hand and threw it into the courtyard, and heard the rolling sound of a stone falling to the ground in the courtyard.

"What the hell, why are the bastards out there throwing rocks into the yard, dead and dead."

"Open the door, we have something important to report, do you hear that? Hurry. Lei Yunfeng spoke in Japanese, and shouted at the door in a stern tone.

"What do you need to come in and report? Bastards, don't you know that you don't have the right to walk into this compound? ”

"I was ordered by General Toshio Kuno of the Special High School to personally send a top-secret document to the director of the research institute, do you understand? If you delay the submission of top-secret documents, you will die. ”

The little devils in the courtyard are all gendarmes brought from the northeast by the Japanese army to develop bacteriological weapons and have great vigilance experience, and they don't look down on the devils in charge of the periphery at all.

At this time, I heard that General Toshio Kuno of the Special High School sent someone to deliver top-secret documents, and the Japanese second lieutenant who was in charge of guarding the courtyard knew the ruthless methods of the biggest spy leader of the Special High School, so he not only softened his tone but asked again vigilantly:

"Who are you, why did you send General Kuno's top-secret documents here, if you don't make it clear, I can't let you into this compound."

"Bastard, I'm Asada Taro Shaosa, the confidential secretary of General Kuno of the Special High Division, and I was ordered by General Kuno to personally hand over a top-secret document to His Excellency the Director, do you have the right to turn me away, so that you are not afraid of military law to deal with me to death?"

The second lieutenant in the courtyard listened to the Shao Zuo outside the door with a cold tone, and his words were ruthless, and besides, Yuanpingshan was heavily guarded, and it would never be so easy for suspicious anti-Japanese elements to sneak in.

He relaxed his vigilance and opened the lock from the inside and pulled out the deadbolt, and the moment he opened the small door and didn't see what was going on outside the door, he was pushed by a tall and strong devil by the neck.

The second lieutenant devil officer was choked by Lei Yunfeng, who was wearing a Japanese military uniform, and quickly advanced into the courtyard, originally wanting to struggle and call for help, but this bastard was stupid to think that this young man who choked his neck must have been impatient to wait before suddenly attacking him.

The six light and dark sentinels on guard in the courtyard, seeing that their second lieutenant commander was stuck by the neck and pushed into the courtyard, one by one, I don't know what happened, and I was about to surround the four people who walked in with guns.

Lei Yunfeng whispered to Fang Shichao, Wang Liang and Su Xiaoyan who followed up: "Kill them, don't leave a single mouth alive." ”

Lei Yunfeng gave the order while his subordinates worked hard, and the second lieutenant who was caught in his hand was choked off his neck.
