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

Zheng Kaixuan took out all the remaining 800 epaulettes and exchanged them for mortar shells.

[Ding, congratulations to the host, consuming 500 Japanese soldier shoulder patches to exchange for rounds of artillery shells.]

[Ding, congratulations to the host, consuming 900 Japanese non-commissioned officer shoulder badges to exchange for rounds of artillery shells.]

1400 rounds of artillery shells are obtained!

Plus there were 600 shells left.

Zheng Kaixuan now has a total of 2000 mortar shells.

This time, he took out 1000 artillery shells and prepared to use them for a night attack.

Of course, he had not used up all of the epaulettes in his hand. There were still more than a hundred left, which were basically the epaulettes of Japanese officers above the rank of lieutenant. He planned to keep these high-level epaulettes in the bottom of the box for emergency use.

"The Fourth Battalion's Reconnaissance Company is responsible for investigating the situation."

"Yes."

The soldiers under Wang Fugui's Fourth Battalion controlled the Triumph UAV, which meant they also controlled all the information sources of the Spearhead Regiment.

Soon, the soldiers of the Fourth Battalion's reconnaissance company had a clear understanding of the situation in the Heiyunkou area.

"Commander, the main force of the Japanese army has withdrawn more than 20 kilometers away. There are no Japanese troops guarding the area near Heiyunkou. They only left a small number of Japanese scouts..."

After listening to the report, Zheng Kaixuan nodded.

"It's just as I expected. Nakamura is planning to use our minefield to stop us. What the hell are these little Japanese guys thinking? Can our mines stop us?"

In order to prevent sneak attacks and harassment from the Sharp Knife Group, Nakamura's camp was far away from the Black Cloud Mouth.

Nakamura felt that only by being far enough away could he sleep peacefully.

After all, the spearhead regiment has a relatively small number of people. If infantry is sent to attack, the Japanese will not be afraid in the flat area outside Heiyunkou.

If the spearhead regiment's tanks want to deploy on a large scale, Heiyunkou is the fastest and most convenient route. Now that there is a minefield there, Nakamura feels that he can basically rest assured.

He never thought that after a fierce battle during the day, both sides were exhausted, and Zheng Kaixuan acted so quickly and planned to launch a surprise attack on his base camp at night.

"Dashan, this time you will lead the Niujiayu militia and escort the Third Battalion Commander out of the mountains."

During the daytime battles, the soldiers of the Spearhead Regiment exerted the most effort, while the soldiers of the militia preserved their physical strength relatively intact.

Zheng Kaixuan gave the task of moving the tank to Niu Dashan.

"Yes, Captain, I promise to complete the mission."

At eight o'clock in the evening, with the faint light from the moon and stars in the sky, Niu Dashan and Yang Wanli, leading more than 800 people, began to cross mountains and ridges and headed towards Wei Zhuang.

Just like when Wang Fugui launched a surprise attack before, everyone was moving forward with heavy loads.

There were more than 800 people, all carrying tank parts and artillery shells.

More than an hour later, everyone arrived near Wei Zhuang. After making sure that there were no Japanese devils around, they came to the road at the foot of Wei Zhuang Mountain and began to assemble tanks quickly.

Twenty minutes later, three Level 13 Triumph mortar vehicles were assembled.

"set off!"

Yang Wanli waved his hand, and three Type 13 Triumph mortars fully loaded with ammunition rushed towards Heiyunkou.

Above the Heiyunkou Canyon, in a dense patch of grass, two Japanese soldiers were lying.

These were two veteran Japanese reconnaissance soldiers, particularly skilled in camouflage. Even the Triumph drone failed to capture their figures.

The two Japanese soldiers had been hiding in the grass for most of the night. During this time, they didn't even lift their arms. It has to be said that they were very dedicated.

"Buzzing..."

At this moment, the vibration sound of the machine came from far away and reached the ears of the two people.

"What's that noise, Kameda-kun?"

"Koizumi-kun, based on my experience, this is the roar of a car engine. Could it be that the brigade commander has sent another locust army to guard Black Cloud Pass late at night?"

"No, Kameda-kun, the sound came from the direction of Weizhuang."

The two were extremely surprised and moved at the same time.

"It's the Eighth Route Army!"

"It's the Sharp Knife Group!"

"Oh no, Kameda-kun, could it be that the armored vehicles of the Sharp Knife Regiment have arrived? Are they planning a night raid on the Locust Army camp?"

"Koizumi-kun, what are you afraid of? Don't forget, there's a minefield at the entrance of the valley. They can't get through!"

Thinking of this, the two Japanese soldiers finally felt relieved and lay back in the grass, staring intently at the ground below.

"Haha, this Zheng Kaixuan is also disorganized in his command. He just sent people to lay the minefield during the day, and then sent armored vehicles through here at night. Is he confused by the locust army's pursuit?"

"Who says it's not? His memory is incredible. However, the raid mission tonight was most likely ordered by another commander of the Sharp Knife Regiment without their knowledge..."

"Where are the chariots of the Blade Regiment usually hidden? How can they be pulled out so easily? I remember the Locust Army dug up this area almost three feet deep, but they didn't find any chariots, not even a hair..."

"Okay, Kameda-kun, that's not something we should worry about. What we have to do now is just wait and see!"

"The spearhead regiment laid their own mines, blowing up their own tanks. It's interesting to think about it, hahahaha..."

The two Japanese soldiers lay in the grass, ready to be spectators.

They could already imagine the Sharp Knife Regiment's tanks being blown to pieces as they passed the entrance of the Black Cloud Valley.

"coming."

In the blink of an eye, three Triumph mortar vehicles arrived at the valley entrance, only thirty meters away from the minefield.

"Crench!"

The car stopped.

"Drive forward, drive forward quickly..."

The two Japanese soldiers kept shouting in their hearts, hoping that the car would continue to move forward and then be blown to pieces.

Inside the tank, Third Battalion Commander Yang Wanli turned on the flashlight and glanced at his pocket watch.

"Xiao Wang, is it twelve o'clock yet?"

Before setting off, he and his co-pilot checked the time on their pocket watches.

"Commander, we're here. It's already 12:04."

"Okay! You can pass now!"

The expiration time for this batch of mines is twelve hours later.

Wang Fugui placed the order at noon sharp, which means it will officially expire at midnight.

Yang Wanli didn't feel any fear.

Once the Triumph Mine came out, he and Wang Fugui, as the battalion commander of the artillery battalion, were the first people to come into contact with this new weapon.

They had already conducted experiments countless times in the mountains, and each time it took effect and failed on time without any accidents.

"go!"

Yang Wanli stepped on the accelerator and drove the Triumph mortar vehicle through the valley entrance first.

“It’s going to explode, it’s going to explode…”

The two Japanese scouts raised their heads, staring at the bottom of the valley with great anticipation in their hearts.

However, the scene they expected did not appear.

Three Triumph mortar vehicles passed through the valley entrance unscathed.

The two Japanese scouts were immediately stunned.

"Could it be that their mines only target the Locust Army and not the Eighth Route Army?"

"How is this possible? This is outrageous!"
