"The gun can solve problems in many occasions, but it may not be able to cope with all situations. In addition, melee skills are also a key training content." Yuri said, finding two standard military daggers without blades from a corner of unknown origin, throwing one of them to the ashes.

"There are also protective gears, and they are also worn. Although they have never opened the blade, it is more than enough to penetrate your thin little body bone." Yuri's hand made a magical appearance to practice close-fitting hand-to-hand combat.

After Ash finished putting the protective gear, Yuri walked to him with the dagger: "Margaret and I have known about you. I think since you can survive in that kind of ghost place for ten years, then you must have your own melee tactics. Now, try to attack me-"

As soon as Yuri finished speaking, Ash leaned over and rushed towards him, pointing the dagger in his hand directly between Yuri's eyes!

"Hmm? Military hand-to-hand combat technique?" Yuri narrowed his eyes with interest, lifted the dagger in his hand slightly, preparing to block the ashes' stabbing.

Military hand-to-hand combat techniques are part of the basic training content of the Rhine Emperor soldiers. They are the most used melee skills except for bayonet fighting techniques. The weapons suitable for this kind of combat techniques are generally one-handed daggers with shorter blades and military daggers.

Since it is a killing skill in the army, it is natural to be straightforward. The dagger in Ashes's hand stabbed Yuri's key points without any fancy, and the response speed of both sides was the speed of reaction.

Yuri is also familiar with this fighting technique. This straight sting of Ashes is one of several commonly used starting styles. As long as he can block or dodge this sting, he has more than ten ways to counterattack against Ashes.

But at this moment, Ash shook his wrist hard, and a silver light flashed across the knife surface. Then, he rushed forward. As the speed suddenly accelerated, the tip of the knife moved down dozens of centimeters, turning the attack target from Yuri's eyes to his abdomen!

This move is not recorded in military fighting techniques, because this move is very risky. Once the blade fails, the whole person will easily lose balance...

However, this move is also extremely tricky - anyone who is pointed at the eyes or face by a sharp blade will subconsciously focus on the opponent's sword. At this time, a sudden move will change the target to attack the enemy's lower abdomen. The enemy may be caught off guard. Once they succeed, the next step will be several fierce pokings, which can kill the enemy within a few seconds or make them lose their ability to resist.

"It's interesting-" Yuri's mouth twitched slightly. In fact, when Ash shook the tip of the knife, he had already had a premonition that Ash wanted to change his moves. In terms of combat experience, he was really much richer than Ash - even if he graduated from the Support Department, a department that seemed to have nothing to do with head-on combat.

The dagger, which was originally raised to the height of his face and was about to block, cut it down in an instant, hitting heavily on the dagger's hand in Ash's hand, then quickly bullied himself, took the initiative to narrow the distance, and a quick knee hit Ash's chest!

The moment the dagger was released, Ash flew backwards and fell to the ground!

"Ahem cough cough..."

Ashes felt an unbearable severe pain coming from his chest. At the same time, his lungs seemed to be flattened, and a suffocation also came. He coughed subconsciously a few times, but the ups and downs of the chest caused by the cough instantly increased the pain several levels. Yuri's knee bump broke at least three of his ribs, and the broken bones were inserted into the flesh. With a slight movement, it was extremely painful.

He has lost the ability to continue fighting. If this is on the battlefield, Yuri can cut off his neck just by taking a step forward.

"You are not fast enough and your strength is too weak. This is your biggest weakness." Yuri reached out and pulled Ash up, helped him get the broken bones, then took out a few more ointments and put them on Ash's chest.

The ointment quickly penetrated through the skin, and a burning sensation suddenly spread throughout the ashes, but the pain at the fracture was quickly eliminated, and even the blue-purple blood stasis was subsided at a speed visible to the naked eye.

"This is a bone injury ointment specially provided by Huangquan Training Camp. You can't get such a good thing outside. I once wanted to steal some and get it to the black market to sell it, but unfortunately I was caught by the instructor. That bastard was almost beaten to death by him with a whip." Yuri said while helping the ashes with medicine.

"..." Although Ash maintained a half-doubted attitude towards Yuri's "story", he had to admit that the effect of this special ointment was indeed amazing. In less than ten minutes, all the pain caused by the fracture in his chest had disappeared. He tried to turn his upper body, but there was no feeling of discomfort.

"But then again, your sword is indeed sinister enough. I made a counterattack action out of combat instinct, which will hurt you inadvertently, which is enough for you to be proud."

"I don't think I'm proud of being injured by someone." Ashes reached out and rubbed his chest, "Do you want to continue?"

"Slow down first. Even if there is special medicine, it will take time for the broken bones to grow. I don't want you to drag your wounds into the assessment site. Now we can learn something else first." Yuri curled his lips and pointed to a cabinet in the corner of the room. The cabinet was filled with various metal ingots, molds and semi-finished mechanical parts.

"You have seen the design drawings of the Zero Steam Gun. Let's start with the simplest but most important place - the barrel. Now, find all the materials for assembling the barrel."

The barrel of the steam gun is indeed the part with the least parts on the Zero Steam Gun, but there are as many as seventeen components. Fortunately, the Ashes have the ability to remember everything. After just taking a few glances at the design drawing, he has already remembered the names, shapes and uses of all the parts.

The main body of the steam gun barrel is a chrome alloy seamless steel pipe with a metal strength of more than level 5. This kind of thing can only be made with a large forging mill. In Yuri's customized material purchase plan for Ash, chrome alloy seamless steel pipe is one of the few finished parts, but just one tube will cost nearly 800 material points.

Ashes soon found a suitable chrome alloy seamless steel pipe, with a length of 45 cm, an inner diameter of 8 mm, and four right-hand rifles. The Zero Steam Gun used this standard barrel.

In addition to seamless steel pipes, the barrel also includes sealing rubber rings, pressure relief valves, ventilation pipes, etc.... Unlike steam guns and flints, the projectiles are completely driven by compressed steam. If the air seal cannot meet the standards, the power and accuracy of the shooting will be greatly affected, and there will even be a risk of explosion.
