This killer star of the War of Resistance Against Japan was only 9 years old.

Zhang Mingxing strode into the air-raid shelter entrance, and a strong smell of blood immediately hit him as soon as he entered.

He frowned and quickly took off his gloves to cover his mouth and nose.

He took out a flashlight from his pocket and continued walking inside.

As they walked, they shone their flashlights on the Japanese corpses on the ground, but they could tell from the direction the corpses fell that they were running out of the air-raid shelter.

This puzzled Zhang Mingxing. Many Japanese soldiers outside were killed by artillery shells. What was in the cave that made these Japanese soldiers, who had an air-raid shelter, run out instead of taking cover, and most of them were shot in the back?

Given the combat skills of the Japanese troops, what terrifying thing could have happened inside to make them lose their confidence in fighting?

This was a situation Zhang Mingxing had never encountered before.

Another question arose in Zhang Mingxing's mind, but Zhang Mingxing did not stop.

Instead, they carefully stepped over the Japanese soldiers' corpses and continued walking into the cave.

When Zhang Mingxing reached the first corner of the air-raid shelter.

The flashlight shone into the passageway behind the corner, and Zhang Mingxing saw the scene inside.

I felt an itch in my throat, a chill ran from my tailbone straight up to the top of my head, and at the same time, I felt nauseous and vomiting.

Zhang Mingxing swallowed hard, forcibly suppressing the churning in his stomach, and planned to examine the Japanese corpses in the passageway more carefully.

I want to see if there are any clues left unintentionally by those mysterious people.

At that moment, a cold wind blew in, carrying with it the heavy smell of blood in the tunnel, mixed with some indescribable odors.

It hurtled straight at Zhang Mingxing's face.

The pungent, strong smell, combined with the scene before my eyes.

Zhang Mingxing couldn't hold back any longer. A wave of acid reflux hit his stomach, and he quickly covered his mouth and rushed out of the air-raid shelter.

As soon as he rushed to the entrance of the air-raid shelter, just like his subordinates before him, he leaned against the stone wall with one hand, bent over and vomited incessantly.

It seems like his reaction is even stronger than his subordinates' before.

Zhang Mingxing felt like he could vomit his stomach out.

The subordinate sitting next to him, who had stopped vomiting, saw his captain vomiting incessantly and the images of the air-raid shelter flashed through his mind again.

Immediately, another wave of acid reflux and nausea hit her, and she joined Zhang Mingxing in vomiting.

Li Fei and his men exchanged bewildered glances, wondering what could possibly be inside that could cause both of them to vomit like this.

Some of Zhang Mingxing's subordinates, who didn't usually like him, thought to themselves, "With this little bit of mental fortitude, he's not fit to be our captain."

Ten minutes later, Zhang Mingxing's Blue Party Special Agent Team, pale-faced, prepared to go and check out the Japanese soldiers' artillery positions.

They had already determined the direction of the artillery position by the landing point of the shells, but at first they thought it was the Japanese artillery position.

Moreover, none of them wanted to stay there any longer; they never wanted to see the scene inside the air-raid shelter again.

They quickened their pace and headed towards the artillery position that Bai Luo had previously placed.

The team members who were conducting surveys on the mountain also returned.

Xiao Zhao looked at his teammates and captain, who had only been separated for less than half an hour; they were all pale and weak.

Xiao Zhao was very puzzled.

"you……"

Zhang Mingxing seemed to have seen through Xiao Zhao's thoughts. Not wanting to bring up this embarrassing matter, he immediately coughed twice to interrupt Xiao Zhao's question.

"Xiao Zhao, you're the most knowledgeable about explosives in our team. What did you find up there?"

Xiao Zhao was interrupted by Zhang Mingxing when he heard Zhang Mingxing mention serious matters, so he quickly suppressed his gossipy nature.

He said seriously, "Captain Zhang, those Japanese soldiers in this regiment really deserved to die. I just roughly measured it. The shelling range is about 2 kilometers."

Judging from the craters created by the explosions, they could not have been caused by light artillery like mortars; they must have been caused by field guns with a caliber of at least 75 mm or larger, or howitzers.

These cannons were extremely destructive.

By observing the impact points of the shells and the numerous craters on the ground.

Based on the duration of the shelling explosions we heard, we can draw the following conclusions.

In about 10 minutes, the Japanese soldiers of this regiment were attacked by at least several thousand to tens of thousands of shells, all of which were from large-caliber artillery.

"How much... how much?"

Zhang Mingxing was no longer calm after hearing the number of around 10000 shells, especially since they were large-caliber artillery.

Moreover, it was fired in just over 10 minutes, and what shocked him was not the number of shells.

It's the time involved. It's not uncommon for a battle to fire more than 10000 shells, but a battle can last a very long time.

On this mountain, however, a scene unfolded where more than 10000 shells were fired in 10 minutes.

Based on this timeline, Zhang Mingxing could be certain that these mysterious people possessed a vast number of artillery pieces.

This also rules out the possibility that the group was just a small team of a few dozen people.

To achieve such terrifying firepower coverage in such a short time, the Blue Party would need at least three artillery divisions firing simultaneously to achieve such a massive output. (This is just a guess, don't take it too seriously.)

Moreover, this was done without considering the lifespan of the artillery.

But he was even more puzzled. Where did these people come from? Their intelligence agency had no information about them at all.

Based on previous intelligence, it could only be determined that it was a small team of at most a few dozen people.

But now it is clear that this judgment is incorrect.

Having reached this conclusion, Zhang Mingxing quickened his pace again. He couldn't wait to determine from the traces left by the artillery fire just how many cannons these people had brought over.

Half an hour later, Zhang Mingxing and his team members climbed up the high ground where Bai Luo had previously set up artillery positions, panting heavily.

But I was a bit dumbfounded right from the start.

The numbers are wrong; there are only two vehicle tracks here, and the distance traveled is very short.

It looks like they erased the tire tracks during the evacuation.

There is absolutely no trace of anything else. (Note: Ground traces were also erased after the medium-sized artillery base disappeared.)

Zhang Mingxing was confused, and his team members were also somewhat dazed.

After a long while, Li Fei finally tried to speak:

"Was it cleaned up by those people, just like these tire tracks? Or did we miscalculate our location?"

Hearing Li Fei's guess, Zhang Mingxing rolled his eyes at Li Fei.

"The location is definitely right, but I just don't know how these people managed to transport so many artillery pieces here and then away? This slope is quite steep."

He pointed to the spot where they had come up, because this was the only place with the flattest ground, suitable for transporting artillery.

But when they came up, they didn't see any tracks left by the transport of artillery.

Everyone, including Zhang Mingxing, was completely baffled and couldn't figure it out.

In the end, he could only return to the city with questions and send the intelligence he had gathered and some battlefield photos he had taken back to headquarters.

They were at their wits' end; they had no way of starting and could find nothing to investigate.

But two days later, they received a direct order from the city headquarters.

Tell them to go to the Red Party tomorrow to receive something.

It's a head... the head of the Asaka Palace Bird.
