"What you said completely subverted my whole concept, and there is still a lot to do. I can understand it quickly, but these things you said are things that we never thought of, such as this parachute, rope landing or something. Liu Fei kept taking notes while Ye Wenqin was talking.

"This is actually back to equipment research and development, these are some of the ways I have been blindly thinking about engaging the enemy in the past few years, and they are also the ideas that came after taking an airship. And these need to be supported by corresponding equipment. Ye Wenqin said excitedly, the parachute is something that has never appeared in the Firmament World, he wants to strike while the iron is hot and tell these things that have been formed in his previous life here.

There is no way to tell many of his ideas directly to others, and even his father and grandfather are not qualified enough, because the level they are at is not enough, if they are rashly reported, these ideas will either not be taken seriously, or they can be widely spread in the report level by level, and lose their secrecy.

"The airship allows us to realize the dream of flying in the blue sky, and now most of the airships are also equipped with equipment such as the rappelling chamber, but the huge noise of the rappelling chamber when using and the violent impact force when landing make this equipment can only be used for escape most of the time. So I was thinking if there was any other way to allow us to land quietly and smoothly, and then after I received the knowledge of air resistance, I thought of a way, which is to use an umbrella-like device, using a large air resistance, to achieve the purpose of slow landing, this is a few sketches I made, but I have not actually used it, but I think this idea is still feasible, that is, it needs to go through a lot of experiments. Ye Wenqin picked up a drawing he had just finished drawing and handed it to Liu Fei, in fact, it was a sketch of a paratrooper umbrella that he had used countless times in his previous life. The rest of the paper was covered with drawings such as clothes, vehicles, and even boats.

"Yes, this one is absolutely doable. It's a priceless treasure. Liu Fei looked at the patterns he had never seen on the paper, his brain was running rapidly, don't look at how to fight and kill every day, but as the person in charge of the Equipment Development Department of the Ministry of State Security, he still knows a lot of scientific knowledge, and soon understood the principle and function of this parachute.

"And the rope landing requires our airships to quickly and covertly engage the enemy, and quickly reach the ground through ziplines over the enemy to fight, and the current airships have not yet met this requirement," Ye Wenqin said again, pointing to the two airships he drew on the side.

"The two you drew don't seem to have the same purpose. Liu Fei looked at the two airships with very different appearances and asked.

"Yes. This slightly larger one is delivered as a personnel, and the requirement is to be able to load people, and it is necessary to act under the nose of the enemy or even in front of him, and it also needs to have a strong defense, and this smaller airship that belongs to tactical support can flexibly carry out battlefield support in action, but I know that some of the heavy weapons we have developed can do this. Of course, they all have to be characterized by low noise and low visibility. Ye Wenqin's drawings are almost a copy of the Black Hawk and Apache, only the propeller position is replaced by the power suspension device here.

"Okay, you can tell me all at once, I'm your student now, and I'm going to take this lesson well. Liu Fei was no longer surprised, he felt that he would not be too surprised if anything popped out of Ye Wenqin's head.

"The rest is still in terms of the selection of individual equipment, and special operations have much more requirements in terms of equipment than ordinary operations. ”

"Oh, so tell me what your ideal individual combat equipment looks like? Liu Fei sat there quietly, like a studious elementary school student.

"Well, a bit of an idea. Now that he has said it, Ye Wenqin is not ready to hide anything anymore.

"Tell me about it. With Ye Wenqin's continuous throwing out of dry goods, Liu Fei has more confidence in the reform of the Ministry of State Security.

"In fact, equipment and cooperation are complementary to each other, our Ministry of State Security is facing operations, must be in a variety of forms, at this time the ordinary standard equipment is no longer quite in line with the needs of our operations, in this case, we need to be equipped with special equipment that meets the needs of the corresponding tasks, some of these equipment can be improved on the basis of standard equipment, that is, for the improvement of the corresponding combat missions, but also specially designed special combat equipment. I divide them into the following broad categories. At this time, Ye Wenqin's face exuded a confident glow.

"The first is clothing, although the contractor has phantom armor, and the warrior also has his own armor, but I suggest that it is necessary to equip a special combat suit outside these phantom armor and armor, such as the light gray combat uniform in the desert, the army green combat uniform in the forest, the black combat uniform used in the night raid, and the snow-colored combat uniform used in the snowy battlefield. The sound of footsteps, spiritual power fluctuations, and soul fluctuations play a role in masking. Of course, it would be better if it could also provide some protection. Ye Wenqin said and drew a set of forest camouflage uniforms worn in the army in his previous life on paper.

"Yo, this style is very similar to the style of outdoor clothes pushed out by your family. Liu Fei remembered the Ye family's outdoor suit that his son bought.

"Well, I call this forest camouflage, you see, if you wear such clothes, even if you don't have the spiritual power shielding and other abilities I said, but hiding in the forest, it can play a good role in concealment, and it doesn't need any spiritual magic and magic circle to cooperate, and it won't cause spiritual power fluctuations. Moreover, various pendants can also be added to this kind of clothing according to the user's habits, such as special backpacks, hanging bags, belts, etc.," Ye Wenqin explained.

"There are so many sayings for one dress, and I take it. Liu Fei gave a thumbs up and praised.

"If you only need optical concealment, the cost of this kind of clothing will not be too high, and you can equip a large number of troops, so that the troops can better conduct ambush operations. Ye Wenqin said.

"Yes, now the military still accounts for the vast majority of the military, so their reconnaissance is also the naked eye reconnaissance, with this thing, the Ministry of Defense can die of joy. Liu Fei snatched the sketch in Ye Wenqin's hand, in fact, every picture drawn by Ye Wenqin had been carefully placed by him.

"After talking about clothes, then the most important thing is the weapon, individual combat basically does not use heavy weapons, such as what large shock guns, armored vehicles, so the power of individual weapons is very important, close-range weapons like knives, guns and sticks have been developed to the extreme, we contractors have phantom soldiers, warriors will also have special exclusive weapons, and the focus is on long-range, high-powered bows and crossbows, firearms can be used in special operations, I think only when forced or able to destroy all enemies at the same time, the use of spiritual arts is allowed。 Of course, this is where silencer technology or devices are needed that can be used on bows and crossbows or firearms. Ye Wenqin continued.

"Can't you use spiritual arts, then wouldn't our attack power have to be abolished by half, and firearms are still suitable for low-realm battlefields. Liu Fei was puzzled.

"Minister Liu, look, you have fallen into the misunderstanding I just said, that is, you pay too much attention to the power of spiritual arts. Ye Wenqin couldn't help but sigh a little, this deep-rooted thinking is difficult to reverse, "As I said before, all special operations need to be carried out in as concealed conditions as possible, so that the enemy will not realize the attack until he dies is our goal." In fact, the warriors have an advantage over the contractor in this regard, they can control themselves better, and for them, they only need to shield their own qi and blood overflow. ”

"Oh, yes, look at my brain. Liu Fei said embarrassedly.

"Minister, if you don't use your whole body's spiritual power to protect yourself, can the physical protection alone resist the current firearms?" Ye Wenqin asked.

"It's hard, and if I hit the critical position, I'll be seriously injured or even killed. If it's the latest type of blaster, even if I'm already fully prepared, I'll probably be hurt if I get hit head-on. Liu Fei thought about the information he had seen about Skybreaker II before.

"Look, the current firearms have begun to pose a certain threat to a master of your realm, of course, if you are on guard, it will not help, but our enemies are not much beyond the realm. Ye Wenqin said with a smile, "And the current firearms are pursuing penetrating injuries and blasting injuries, and I think high-powered kinetic energy bullets are more suitable for us." This is also some of Ye Wenqin's thoughts in the use of firearms in the past two years, unlike the fragile flesh of human beings in the previous life, the bodies of some cultivators in the Firmament World will have a certain degree of resistance to the penetration of firearms, in the face of contractors or warriors, even if they penetrate the skin, they will be blocked by muscles and bones to a large extent, and it is rare that there will be that cavity effect, so firearms are only widely used in ordinary troops and police forces, and few people in departments like the Ministry of State Security are interested in firearms.

"Kinetic bullets, to be honest, I don't know much about firearms, can you explain a little more?" Liu Fei was embarrassed again, feeling that he was really a primary school student who didn't know anything.

"This kind of bullet is not pursuing penetrating spiritual power and blasting ability, but the shooting distance is relatively close, and it is estimated that it is an effective range of tens of meters. It doesn't need to be too penetrating, and it doesn't need to add explosive devices, what I need is to hit the enemy's body or armor, and what I need is to hit the enemy with a very strong impact on it, damaging the enemy's internal organs. Even if the enemy successfully resists this damage, there is a high chance that it will have a knockback effect. Ye Wenqin explained in detail.

"Good idea, if it's really as you said, then it will be easier to deal with those thick-skinned Vajra Realm martial artists. Liu Fei said happily that when he was in control of the realm before, he had met a master of the King Kong Realm, and it took a lot of strength to achieve the effect of breaking the defense. Although he hadn't fought against a martial artist in the Immortal Realm since he reached the Transcendence Realm, it was a headache to think about.

"Minister, you're half right, this attack method is only suitable for covert sneak attacks, and if you fight head-on, I estimate that few people will be able to hit the powerhouses above the Challenge Realm and the Bone Forging Realm. "This is the biggest limitation of firearms in this world, speed, if the bullet does not have four times the speed of sound, it is difficult for the firearm to cause damage to the people in the vigilant challenge realm and the broken bone realm, because they dodge when the bullet is discharged, and for people in the higher realm, it is possible to need a higher speed bullet.

"With weapons out of the way, the next step is what I think is the most important auxiliary equipment. Ye Wenqin knew that Liu Fei didn't know much about firearms, so he quickly skipped this topic.

"Auxiliary equipment, I am familiar with this, our equipment development department is mainly studying these, such as the use of special high-strength silk threads, camouflage tools, portable dry food, hook locks, lock picking tools and even the development of various small spirit arrays are our strengths. For example, my mask is the latest type, with illusion, anti-spiritual power detection, illusion breaking, evil destruction and strong defense. As the director of the Equipment Development Department, Liu Fei feels that he still has a lot of right to speak.

"Minister, these are actually some basic equipment, just like the detection equipment and communication equipment I said before, as well as special vehicles, including airborne equipment, such as parachutes, special vehicles, special surface and underwater ships, special airships, battlefield first-aid equipment, which can quickly deal with all kinds of injuries, and there are multi-functional knives and shovels and other gadgets. While Ye Wenqin explained, the brush in his hand also kept painting, and by the time he finished speaking, he had already painted more than a dozen. "Of course, these things are my assumptions, and whether they can be realized depends on our current technical level. ”

Liu Fei's mouth was open enough to stuff a big apple, he put his face in front of Ye Wenqin, stared at him with wide eyes, and said, "Good girl, how long is your kid's brain, compared to you, Lao Tzu has lived to be a dog." ”

"I just like to think about it. Ye Wenqin scratched his head and said.

"If I could come up with these things, I'd rather think about them every day. Liu Fei said happily. "You kid must think more about it in the future. ”

At this time, Liu Fei received a message, "What? The Ministry of Defense and the Ministry of Internal Affairs are unwilling?"
