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

Although Zheng Kaixuan's method is not as cruel as Wang Fugui's, it is also very decisive.

His method was to continue harassing the Japanese and resolutely prevent them from getting a good night's sleep.

The Japs could not harass the Sharp Knife Regiment, but the Sharp Knife Regiment could harass them.

The two Triumph UAVs are Zheng Kaixuan’s confidence. After all, the Spearhead Regiment has the conditions.

Starting from the third night, the Japanese soldiers who had just recovered a little from diarrhea fell into an endless nightmare again.

Around nine o'clock in the evening, most of the Japanese soldiers had fallen asleep due to extreme weakness.

A triumphant drone quietly took off.

"boom!"

"boom!"

"boom!"

This drone flew over the Japanese camp and dropped a triumph grenade every few meters.

The 5th-level Triumph UAV can carry grenades.

Just two days ago, Zheng Kaixuan gritted his teeth and took out two Japanese lieutenant colonel epaulettes and upgraded both planes to level thirteen.

The thirteenth-level Triumph UAV has its bomb load increased from five to ten, and its maximum load capacity has reached 20 kilograms.

Not only that, the cruising range has also been directly increased from 20 kilometers to 50 kilometers.

This endurance is enough for several round trips in one night if the aircraft takes off from a few kilometers away.

The two drones worked in shifts, and the Japanese couldn't sleep the whole night.

Ten triumphal grenades were thrown randomly from the sky above the Japanese camp, from east to west, from south to north, to create noise.

Zheng Kaixuan didn't require a high number of casualties; the Japanese soldiers who happened to die under the grenade were just incidental. The main purpose was to let all the Japanese soldiers hear the explosion and prevent them from sleeping!

At night, the area around Heiyunkou Canyon was quiet and peaceful.

The extremely loud explosion of the triumphant grenade made all the Japanese soldiers break out in cold sweats. They all got up and gathered together urgently.

The Japanese even thought that the Sharp Knife Regiment had broken into their camp and almost fell into chaos.

However, after struggling for most of the day, they didn't find even a single clue.

Maruyama Sutaku and Saito Sho looked at the bodies of the dozen or so Japanese soldiers who happened to die under the grenade, their faces full of confusion.

"What? Do the Sharp Knife Regiment also have fighter planes? Are they using fighter planes to drop bombs?"

There were shrapnel left at the scene, and based on the shrapnel, the Japanese could judge that the grenade did indeed belong to the Sharp Knife Regiment.

However, they had no idea where these grenades came from and were puzzled.

"That's impossible. Fighter planes usually drop artillery shells. Who would drop such a small grenade? I've never heard of it..."

"That's strange, Saito-kun. From the poisoning incident a few days ago, I felt that there was a problem within our organization."

"There must be a Japanese traitor among us. What a great Zheng Kaixuan! Could it be that he has bribed some of the Locust Army soldiers? Or has the Sharp Knife Regiment infiltrated the Locust Army?"

"General, your analysis makes a lot of sense. I also suspect there's a spy among us..."

Maruyama Sutaku and Saito Sho started to search for spies inside the Japanese army again. They were very busy, but in the end they still found nothing...

11pm.

Another drone quietly flew over the Japanese camp, quickly dropped ten grenades, and then disappeared into the night.

"Bag! Bag!"

This time, more than a dozen Japanese soldiers were killed in the explosion.

Maruyama Sotaku was furious, but there was nothing he could do.

He sent people to question all the Japanese soldiers on duty at night, and the answers of these Japanese soldiers were all very consistent.

That is, no one knows where these grenades came from, and no abnormalities were discovered in advance.

The thirteenth-level Triumph UAV can also fly at an altitude of up to 2000 meters.

In other words, the drone can directly drop bombs at an altitude of 2000 meters, and there is no requirement for the accuracy of the bombing anyway.

At an altitude of 2000 meters, let alone a dark and windy night, even in broad daylight, an ordinary person standing on the ground cannot see clearly a target as small as a drone.

That night, the two drones took turns harassing the Japanese military camp, and they didn't stop until five or six in the morning.

Of course, the main reason for the silence is that the battery is exhausted, there is no power...

After dawn, Zheng Kaixuan did not give the Japanese a chance to sleep.

He ordered the third battalion to pull out several mortars and a large number of blank shells, and began continuous training a few kilometers away.

The rumbling sound of artillery made the Japanese even more panicked and they couldn't sleep at all.

The sound of gunfire continued for a long time before it stopped.

For ordinary Japanese soldiers, this is not only physical torture, but also a double blow to their body and mind.

Ordinary Japanese soldiers would have no idea about blank bullets. They would just think that the Sharp Knife Regiment had so many shells that they couldn't use them all, and that they were just showing off their muscles!

This caused them to feel great fear psychologically, and they dared not go any further into the mountains.

They didn't dare to advance, had no food to eat, and couldn't sleep well. Many Japanese soldiers had begun to collapse.

At night, the two drones continued to harass in turns, and thousands of Japanese soldiers had another sleepless night!

Including the two days of diarrhea before, the Japanese had not had a good night's sleep for four or five days.

Most of the Japanese soldiers now have pale faces, black lips, and huge dark circles under their eyes, looking almost lifeless.

Feelings of anxiety, fear, uneasiness, and panic began to fill the Japanese military camp.

Most of the Japanese soldiers have gone from being full of confidence at the beginning to being extremely anxious.

Morale has almost been lost.

Now, they are no longer thinking about how to deal with the spearhead group.

Now they just want to have a full meal, have a good sleep, and leave here as soon as possible.

Several small-scale riots have occurred in the Japanese military camp. If this continues, they will mutiny on their own without Zheng Kaixuan having to take action.

It was another night, and Zheng Kaixuan sent out drones to continue harassing the Japanese camp.

But this time, from the video footage brought back by the drone, we can see that the Japanese have no reaction to this harassing bombing.

Anyway, I couldn't figure out what was going on, and panicking was useless, so the devil just lay down...

No matter how you throw grenades, they just fall into a deep sleep...

"Captain, it seems your trick is not working anymore."

Wang Fugui was a little depressed. He thought it was quite interesting to play with the Japanese in this way. He had originally planned to harass them for a few more days to make them completely collapse.

Zheng Kaixuan was not panicked, but became more energetic.

"This is a good thing. It just shows that the Japanese are exhausted to the extreme. Now is a good time for us to take action."

"Captain of the First Battalion, Commander of the Fourth Battalion, Commander of the Fifth Battalion, Commander of the Sixth Battalion, prepare your bulletproof vests and helmets, and follow me into the enemy camp to teach them a lesson!"
