PS: At everyone's request, I drank three bottles of Brain Platinum to the protagonist, and my intelligence increased by 20 points.

After filling in the file and laughing a few words with the chick in the archive room, Geng Chaozhong followed the corridor to the office of the intelligence unit on the first floor, looking for the head of the Zhou unit that Liu Yiban said.

Pushing the door in, a thin middle-aged man with glasses in a white coat was sitting behind a desk, holding a magnifying glass and looking around. It was the head of the intelligence unit who went to the fishing village on the west coast with Liu Yiban that day to investigate the scene.

Zhou's name is Zhou Ning, in his forties, he turned out to be a surgeon in the patrol room of the island city during the German occupation, at that time, there was no relevant forensic training school in the Republic of China, and there was a shortage of professional and technical personnel, but anyone with a little professional skill was used as a generalist. Therefore, as soon as Liu Yiban came to the island city, he got Zhou Ning half invited and half tied to the Party Affairs Investigation Section.

After entering the door and exchanging a few words of greetings, they quickly got to the point. Chief Zhou first gave Geng Chaozhong a detailed description of the situation at the time of the incident that day, and then took out a few 7.62X54 pointed bullets and handed them to Geng Chaozhong, saying: "This is the bullet used by the Red Party gunman. “

Geng Chaozhong held the familiar bullet in his hand, full of emotion, but there was no expression on his face, he picked up the bullet and stared at it for a while and said:

"It looks like a bullet in water! It's just that I've seen a bullet with water beads, it seems that the head is round, and it's not as good as this bullet, you look at this incision, look at this brass, tsk, foreign goods! ”

"Captain Geng is an expert! At a glance, you can look at these pieces. Chief Zhou sighed as he took out a few more bullets from an iron box and handed them to Geng Chaozhong.

Geng Chaozhong took the bullet and couldn't help but feel shocked!

These bullets are too similar to my own 79 sniper match! The size is moderate, and it is also a pointed bullet, but the workmanship is a little rougher, and the length and diameter of several warheads are slightly different, but that is only a matter of quality control, as long as you are carefully selected, you can still pick out the right bullet! It's just that looking at the color of the brass under the shell, it should be a long time ago, and I am afraid that the gunpowder inside will be damp and the dud will not be able to excite it.

That week, the head of the unit saw Geng Chaozhong holding the bullet and groaned, and couldn't help asking:

"Did Captain Geng see something?"

Geng Chaozhong looked puzzled, as if something was bothering him:

"These two bullets look the same, but they are definitely not the same batch, and the one you handed me later had the words 107-14 written on the bottom, and the front one had the words 351-08, which should have been manufactured in 1914 and 1908 respectively. But strangely enough, the quality of the 1908 was much better than that of the 1914, which is impossible, unless they were not made by the same factory at all. ”

"That's right!" Chief Zhou slapped his thigh, and suddenly felt like a bosom friend, there are many people who use bullets in this investigation, but there are too few people who understand bullets! He nodded and continued:

"That's what I can't figure out, it's unreasonable, you must know that after the end of the European War, the military industry has made rapid progress, and the quality of bullets is getting better and better, and it is impossible to have a bullet in 08 that is better than a bullet in 14. Unless this bullet is made in China, but the domestic arsenals in Hanyang, Shanghai, Fengtian, and Henan have never made this kind of bullet, and even if it is made, the quality is not even comparable to this 14-year-old, which can be seen at a glance. ”

Geng Chaozhong learned from Chief Zhou, and also frowned and said:

"This gunman is indeed a bit mysterious. By the way, which country is this bullet, I just went to the United States, maybe I can help inquire. ”

Chief Zhou didn't have any excited expression, obviously he was desperate about this matter, he just waved his hands and said helplessly:

"The Soviet, opposite the Governor's Palace, the ammunition of the Russian-made Makqin heavy machine gun. During the 14-year Japanese-German War, the Germans urgently got a batch from Russia, but before they could reach the Governor's Palace, the Germans surrendered, and the bullets were useless. I thought that this bullet was very special, maybe I could find out something, but who knew that it would be such a result. Besides, it's been more than a month, and even if the source is found, the person is estimated to have run away early. ”

Geng Chaozhong's heart trembled slightly, so to speak, there are not only these bullets, but there are also a lot! What is the Maxim heavy machine gun, it is estimated that there are at least a few thousand rounds! It's enough to use it for yourself!

It's just how to get it out of the Governor's Palace, but I have to think about it.

Chief Zhou saw Geng Chaozhong holding the bullet and pondering, thinking that Geng Chaozhong had a headache about the origin of the bullet, but instead comforted Geng Chaozhong and said:

"Captain Geng, don't worry, I can't think of anything for a while, we've been thinking about it for a month, don't we have no clue!"

Geng Chaozhong saw Chief Zhou's eyes, and immediately realized that Chief Zhou was a little impatient, so he raised his head and said:

"Chief Zhou, I thought about it for a long time, and suddenly thought of one thing, the shootout happened 30 minutes after the start of the prison break, and the gunman was able to let his accomplices fall into our encirclement and then do it, this is not like the style of the Red Party! So that Red Party must have just arrived, and it wasn't long ago that it was ambushed there, otherwise it wouldn't have fallen into our trap at all! From the time I heard the gunshots to the time I arrived at the scene, the Red Party gunman must not have been far from Zhanqiao Beach, and I think the gunman must have lived nearby! And the police blockade is so tight, as long as we check, sooner or later he will show clues. ”

Chief Zhou nodded, and suddenly as if he remembered something, he took out an iron box from the drawer and handed it to Geng Chaozhong, pointing to the contents of the iron box and said:

"If you want to talk about clues, there are indeed some, such as the cloth in this box, which should be the things on the gunman."

What, cloth?!!!

Geng Chaozhong's heart suddenly tugged, and he suddenly realized that he was likely to make a fatal mistake.

Struggling to suppress the shock in his heart, Geng Chaozhong took the iron box and looked at it. There was a piece of black and gray miscellaneous fabric the size of a finger lying in the iron box, and it was indeed the fabric on the humble and beneficial long shirt that Liu Yiban gave him!

Over there, Chief Zhou was still introducing to Geng Chaozhong:

"It's just that although this kind of fabric is expensive, it is estimated that there are 10,000 or 20,000 people in the island city who can afford it, and it is impossible to check them one by one, and the bullet was beaten that day, and there is no big hope for this, so I didn't tell the section chief, for fear of being beaten again."

What a fluke! Fortunately, Chief Zhou didn't tell Liu Yiban, otherwise Liu Yiban could see at a glance that this piece of fabric was the same as the fabric of the gown he gave to Geng Chaozhong. According to Liu Yiban's suspicious temperament, then it's a proper end of play!

Geng Chaozhong unfolded the fabric and carefully observed it while carefully recalling the situation that night.

When I sniped the first person that day, I hid behind a dry wood stomping, which should have been the clothes hanging on my body during the pursuit. Who would have thought that such a small detail could be caught by Chief Zhou!

Fortunately, this is in the Republic of China, if it is in modern times, the opponent has 10,000 ways to catch himself!

When you act in the future, you must not wear this kind of Chinese caftan !

Geng Chaozhong's heart was pounding, no, after I went back, I had to quickly burn that long shirt, and then buy a new set!

Geng Chaozhong took the fabric and looked at it for a while, then handed it back to Chief Zhou, but there was still a thoughtful look on his face, and Chief Zhou asked when he saw this:

"What else did Captain Geng discover?"
