A magazine of 30,000 rounds, you call it Hanyang

The cave where the regiment headquarters was located was turned into a weapons modification base by Zheng Kaixuan.

A total of over 2,000 shoulder straps were left over from the last raid on the Japanese Ono Regiment and the remaining ones in Changyu Valley.

Zheng Kaixuan took out 500 of them and modified them into 50 sets of level bulletproof vests.

Now, the Sharp Knife Regiment has a total of 30 sets of bulletproof vests, including 170 sets of level bulletproof vests and sets of level bulletproof vests.

There are a total of 30 bulletproof helmets, including 170 level bulletproof helmets and level bulletproof helmets.

These equipments are enough to arm a special forces team.

The soldiers were holding back a lot of anger in their hearts. Although no one said it explicitly, Zheng Kaixuan knew that they all felt aggrieved.

If Zheng Kaixuan had not tried his best to restrain them, even if the number of enemies outside was ten times theirs, the soldiers would probably have rushed out to fight the Japanese to their deaths.

At this moment, the Japanese were exhausted to the extreme and their morale was extremely low, while the morale of the spearhead regiment was extremely high.

The enemy is weak and we are strong, it is a good time to take action.

"Xizi, you will be in charge of the regimental headquarters. The second, third, and eighth battalions will be responsible for the support. Everyone follow me."

As night fell, Zheng Kaixuan led hundreds of elite soldiers and sneaked towards the Japanese base.

The ridge of the Heiyunkou Canyon extends all the way southward and is connected to the deep mountains and forests where the Sharp Knife Regiment is stationed.

After crossing two big mountains and several small hills, hundreds of people successfully arrived at the hillside not far from Heiyunkou.

After all, there are troops stationed in this area all year round.

The soldiers have daily training in mountain climbing and scaling abilities, and all of them are very skilled, almost as good as professional mountaineers.

Be it steep stone walls, bumpy and rugged mountain roads, or thorny bushes, they are no problem at all for this group of people.

Before reaching the Japanese army camp, there is one more thing that must be done.

That is to get rid of the Japanese secret sentry!

Maruyama Sotaku is able to hold the position of brigade commander, which shows that he has some ability.

He had also considered the possibility that the Sharp Knife Regiment would attack them from the ridge of the Black Cloud Gorge.

Therefore, within a range of more than two kilometers south of the canyon, the Maruyama Brigade deployed no less than ten secret outposts. They lurked in the grass and behind rocks day and night, always on guard against Zheng Kaixuan's sneak attacks.

Of course, this is just what the devils think of as a 'secret sentry.'

In fact, for Zheng Kaixuan, this was not a secret message at all.

With the Triumph drones here, these devils can't hide at all.

During this period, Wang Fugui used two drones to clearly understand the hiding places, firepower configuration, etc. of all the Japanese secret guards.

The Sharp Knife Regiment knew everything, including when they ate and when they changed shifts.

The Japanese were like running naked in front of them, with no privacy at all.

"Song Pengcheng, clear the obstacles and pull out all these nails for me!"

"Yes! Captain."

After receiving the order, the commander of the fifth battalion, Song Pengcheng, led 20 soldiers of the fifth battalion and sneaked into the darkness ahead like a ghost.

They did not carry long guns. Each of them had a Hanyang-made fully automatic rifle on his waist and a dagger in his pocket. Their main goal was to fight lightly.

The 20 soldiers were divided into ten groups and each groped their way towards their designated target area.

Behind a huge rock, a Japanese soldier was hiding with his eyes slightly narrowed.

His location was very secluded. In front of the huge rock was a cliff with a drop of more than ten meters. It was difficult for ordinary people to climb up from here.

Even if someone could climb up, they would definitely make noise and be discovered by him in advance.

He felt that as long as he kept an eye on the direction of the bushes on the other side, he would be safe.

"There are still several lines of defense ahead. It's impossible for the Sharp Knife Group to reach me without being discovered. I'm going to sleep for a while before I work..."

The diarrhea and poor sleep over the past few days have made the Japanese sentry exhausted, so he couldn't help but want to take a break.

At this moment, a hand suddenly appeared from the darkness and rested on his shoulder.

“Sh…Wu——”

This sudden hand frightened the Japanese sentry so much that he was almost scared to death. He couldn't help but turn his head and wanted to shout.

Just when he had not finished uttering the word "who", and had only called out the first two pinyin letters, a big hand covered his mouth tightly.

"laugh--"

Immediately afterwards, an extremely sharp dagger pierced through his chest and pierced his heart.

The Japanese sentry never saw who killed him until he died.

At the same time, the same scene is constantly being played out.

Some Japanese sentries had their necks twisted by the sharp knife regiment soldiers, some had their mouths covered and daggers stabbed into their hearts. Some died of blood loss from slashed aortas, and some were suffocated to death by having their mouths and noses covered.

In less than half an hour, all the Japanese secret sentries were eliminated, and almost no sound was made.

Song Pengcheng completed this wave of sentry-finding missions quickly and cleanly, and it was extremely beautiful.

A moment later, a purple beam of light flashed briefly in the direction of Zheng Kaixuan.

It is the laser on the solar-powered intelligent optical telescope. This little thing is now used by the Sharp Knife Group to transmit information in the dark, which is very convenient.

The laser flashes for a very short time, only a few tenths of a second.

It was because Zheng Kaixuan and others had been watching that they discovered that the Japanese were completely unaware of this.

"Let's go! Let's go!"

The Japanese secret sentries were eliminated, and Zheng Kaixuan had no more worries. He led hundreds of soldiers and quickly came to the front, where he met up with Song Pengcheng and others who had been waiting there.

"Second Battalion Commander, you will lead your troops and stay above the canyon to provide support."

"The first, fourth, fifth, and sixth battalions will split into four groups and proceed according to the original plan."

"Yes! Captain!"

"Yes!"

"Guaranteed to complete the mission!"

Everyone agreed and led their respective troops to rappel down from the bottom of the black cloud and rushed into the enemy camp.

Including Zheng Kaixuan, there were only thirty people left at the scene.

Although these thirty people are the smallest in number, they are the main force of this operation.

They are truly fully armed, all wearing level 12 bulletproof equipment and carrying a variety of weapons and ammunition.

This time, they will be led by Zheng Kaixuan personally to carry out combat missions.

Zheng Kaixuan waved his hand.

"Brothers, our mission is to attack Huanglong and break into the enemy brigade headquarters. Let's go!"
