Conan: The truth lies only within the range of fire

Kamiya Minatsuki prepares to act as a frogman and destroy Gin's submarine.

There is a shoulder bag at the port, which was placed there in advance by Kudo Shinichi and asked Dr. Agasa to leave it there.

Inside are oxygen bars, diving goggles and underwater thrusters.

Minatsuki Kamiya put on diving goggles, then adjusted the communication function of the diving goggles and established contact with Shinichi Kudo and Shuichi Akai.

Kamiya Minatsuki said: "We will directly carry out blasting operations on the submarine to prevent it from being discovered by the submarine detection system. Akai, you will interfere when the time comes."

Akai Shuichi said seriously: "Report your position at any time. I came here in a hurry, so I only prepared a rocket launcher."

Kamiya Minazuki complained: "I really don't know what you were thinking this time. You let a kid determine the location of the submarine and then use rockets to bombard the submarine underwater. Do you really think that water resistance does not exist? And this Pacific buoy is also a fake. It only launches guided missiles and does not even have anti-submarine weapons.

Underwater combat is the most troublesome. Many of my weapons are of little use, unless I build a launching turret to fire anti-submarine rocket depth charges. But now there is obviously not enough time for me to build a launching turret. Really, next time you fail, tell me earlier, otherwise there will be no need to go through so much trouble!

After spending a lot of time to figure out a Panzerfaust III rocket launcher to deal with a Soryu-class submarine, you are really amazing. "

Akai Shuichi was surprised and said, "You can also launch anti-submarine rocket depth charges? Don't you only have individual combat weapons?"

Kamiya Minatsuki sneered, "You can only think of it, but I can think of it. Some weapons need to use firing turrets as ignition devices to provide kinetic energy. I just don't want to use them because it's too troublesome. If you want to see it, I'll show you next time, okay?"

The corner of Akai Shuichi's eye twitched: "Uh... no need."

The anti-submarine rocket depth charge, which is composed of a warhead, a solid rocket engine, etc., is basically a ship-borne turret and can basically not be used as a single-soldier weapon.

The main reason why individual weapons cannot fight underwater is that the density of water is much greater than that of air, which causes the ammunition to have an extremely short range and unstable trajectory underwater.

Water is 800 times denser than air, which means that ammunition encounters much greater resistance in water than in air.

Conventional firearms rely on the rotational stability of the bullet to maintain range and accuracy, while rockets are propelled toward the target by the reaction force generated by the rocket engine. However, underwater, due to the lack of a stable rotation axis and huge resistance to movement, the trajectory becomes unstable, resulting in an extremely short range, generally not exceeding 2 meters.

In addition to the ammunition issue, the use of individual weapons underwater also involves the performance of the weapons themselves. Since the inside of the weapons is no longer air but water, strict requirements are placed on the quality of the weapons.

The use of individual weapons underwater is subject to multiple restrictions, including the stability and range of ammunition, the performance of weapons, and the physical properties of water, making it almost impossible for individual weapons to meet the needs of underwater combat.

Although firearms have supercavitating underwater bullets, that is, after the bullet leaves the barrel, under the action of the bullet tip plane, the bullet body is wrapped in cavitation during the entire flight process, and the resistance it encounters is greatly reduced compared to flying in water.

However, rockets used by individual soldiers in combat cannot be applied to supercavitation technology because the rockets are too large and require extremely powerful ignition power to support them, which individual rocket launchers cannot support at all.

Kamiya Minatsuki put on the three-dimensional mobile device and said to Kudo Shinichi: "Okay, let's go."

"Ok!"

Just as Kamiya Minatsuki and Kudo Shinichi were about to enter the water.

"Shinichi! Mr. Kamiya!"

Kamiya Minatsuki and Kudo Shinichi turned their heads and looked behind them in disbelief.

Kudo Shinichi said anxiously: "Xiaolan? Why are you still here? Shouldn't you retreat?"

Mao Lilan lowered her head slightly: "I...I felt you, so I came over. Where are you going?"

Kamiya Minatsuki said helplessly: "Feeling? What? You and that little brat Huibara have both awakened their radars!"

Kudo Shinichi sternly warned: "Xiaolan, leave with them immediately. Kamiya and I will solve this crisis!"

Mao Lilan said worriedly: "Just the two of you? Wouldn't that be dangerous? I'll go with you!"

Kudo Shinichi said with a straight face: "What are you talking about? What you need to do now is to leave with everyone! Kamiya and I will solve this crisis, and we will come back safely! Leave now!"

At this time, Dr. Agasa also came, and with him was Haibara Ai.

Professor Agasa came to find Mouri Ran, but on the way, he met Haibara Ai who had not left yet.

Kudo Shinichi frowned and asked, "Why are you here too?"

Huiyuan Ai spread her hands and said, "I didn't see you guys, so I looked for you."

Kudo Shinichi shouted to Dr. Agasa: "Doctor, take Xiaolan and Huiyuan away quickly, it's very dangerous here!"

When Dr. Agasa saw the attire of Kamiya Minatsuki and Kudo Shinichi, he guessed that the two were going to carry out a dangerous mission.

Dr. Agasa knew that they couldn't help much if they stayed here, so he nodded and said, "I understand, Xiaolan, Xiaoai, let's leave here quickly and leave this place to Shinichi and Mr. Kamiya."

"Why are you still here?"

Kanji Ushio drove a speedboat to the port and said, "Hurry up and leave. It's very dangerous here. Many people have already left. I'll take you away!"

Kudo Shinichi said to Mao Lilan with a serious expression: "Xiaolan, I will come to see you after I finish my business!"

Dr. Agasa took Ran Mouri and Ai Haibara onto the speedboat.

Ushio Kanji looked at Kamiya Minazuki and Kudo Shinichi in confusion: "Why don't you two come up?"

Kamiya Minatsuki rolled his eyes and said, "We're going up there, so you're going to blow up the submarine?"

Kudo Shinichi said to Ushio Kanji: "Mr. Ushio, we still have things to do. You should take them away first."

As the speedboat started to sail away, Mao Lilan shouted loudly: "You must be careful, and you must come back safely!"

Kamiya Minatsuki said to Kudo Shinichi who was reluctant to leave: "Okay, stop looking, there is not much time left, let's go quickly."

Kamiya Minatsuki looked at the water columns exploding on the sea in the distance. It seemed that the frequency of torpedo and guided missile launches was getting higher and higher.

In addition to the safety reasons of Mao Lilan and others, Kamiya Minatsuki also wants to keep the Pacific buoy. After all, the virus program was successfully implanted, and the function of realizing global facial recognition based on surveillance images is quite useful.

If they can use the function, they won’t have to worry about finding people in the future.

Kamiya Minatsuki and Kudo Shinichi jumped into the sea together to look for the submarine where Gin and the others were.
