"Come on, you try." The use of the glass explosion-proof shield is not difficult, and it is easy for Nobuko to get started.

Lu Zhiyi gestured and asked for a standard waist knife from the hand of the city lord's palace guard, "Xiao Xinzi, resist, I'm coming." "When you speak, it's brute force.

Bell Bell Bell ~~~ Lu Xin easily resisted, and even played a trick and showed off a wave of one-handed shields.

He wrapped the wristband around his left arm and held the handle behind his back with his left hand, so that his right hand was free, and he could also wait for an opportunity to attack, and his flexibility in using the shield was greatly improved.

"Hey, I forgot you know martial arts." Lu Zhi moved his wrist that was shocked, and quickly returned the waist knife, "Actually, this shield is mainly for ordinary people with more strength. ”

As soon as Xiao Xinzi heard that the fourth brother had something to say, she suppressed her desire to continue to explore and returned the shield to the sapper.

"Now is a special period, and the catchers in the city can be elite soldiers, but we have to think about it in the long run."

Lu Xin nodded, and Lu Zhi continued, "Usually there are no big cases in the city, and generally just catch some small thieves, at best, they will catch a big thief or something, and when the time comes, just find some strong men who are familiar with martial arts to act as a quick catch." ”

"This shield is for them, right?" Nobuko was just curious, in fact, his combat effectiveness with a shield was far inferior to that with a sword.

"yes, and you don't usually need it, just make a few sides and store them in case you need them."

Lu Zhi actually came according to the configuration of the SWAT team, when the arrest is fast and the master of encirclement and suppression is needed, this shield will play a great role, and it can save his life at a critical moment.

Saying this, Xiao Xinzi was not very interested in the explosion-proof shield, he turned to take the sleeve arrow to check, "Hey, fourth brother, how can this not be an arrow, but a hook?" ”

"It's for climbing walls, and when you press the machine here, the hook will shoot out with the rope." Lu Zhi took off the hook alone, "When the time comes, this hook will hook the wall, and the catchers will be able to use their strength to climb over the wall." ”

"It's for the average person again?" Xiao Xinzi said casually, and then shook his head, "No, I think this can be used in many places, and it's quite practical." ”

Foreman Lu nodded again and again, "What the little boy said is good, especially when he goes into the mountains to hunt, it is very useful." ”

Lu Zhi shrugged, he just casually drew some drawings and handed them to the sappers, as for whether the finished product could really be used, he didn't care very much.

However, the next two things, those are his painstaking efforts, one of them, the three-edged army thorn; Second, the iron ruler.

…………

Squeak squeak ~~~

A rabbit was carried upside down by the sapper, and Lu Zhi took the three-edged army and stabbed it at once, as if he hadn't been stabbed to death, and he twisted his wrist and stirred it, and then pulled out the knife.

Xiao Xinzi slapped his head directly, the fourth brother is good at everything, but he doesn't know martial arts, but he won't be powerless, but his skills are too poor, I'm afraid that he won't be able to stab the little rabbit at once.

Then the truth was not what Lu Xin expected, Lu Zhi stabbed the rabbit and bled non-stop, and soon died, the cause of death was heavy hemorrhage.

Lu Zhi nodded with satisfaction, this situation was similar to what he expected, "I will have a roast rabbit in a while, but let's take a look at this corpse that sacrificed his life for the sake of technological reform." ”

The sapper carrying the rabbit handed over the silk scarf that had been prepared a long time ago, Lu Zhi shook his head and shook his hand casually, because of the silk gloves, there was no blood.

"Look at the corpse?" Because Lu Youshou and the sappers had experimented in advance, their interest was not high, and among all of them, Lu Xin was the most inquisitive.

"Ah, it turned out to be a hole, no wonder the blood doesn't stop flowing." Soon, Nobuko discovers the blind spot.

Lu Zhi smiled proudly and pointed to the three-edged military thorn to show him, "The dagger must have enough lethality, in addition to the weight, center of gravity, curve, and sharpness, what is especially important is the severity of the wound caused and the difficulty of pulling it out after stabbing in." ”

There are often such clips - someone can survive after being stabbed, and once the knife is drawn, it will immediately GG.

It is also easy to find pictures of various "world's N famous knives" on the Internet, and they all achieve the same purpose through various details and different designs.

Therefore, the body shape is narrow in the front and wide in the back, the blood groove on the side of the blade, and the serration at the base of the blade...... These characteristics exist for this purpose. The Triangular Thorn was once one of the most powerful swords, presumably due to its structural shape.

Hey, this is also the purpose of Lu Zhi's reproduction of it, how handsome!

He really liked this cold weapon.

…………

"Master Junma, tell us more about it."

Lu Youshou has seen the drawings and already knows the principle, he said this to make Lu Zhi more transparent, and by the way, communicate more with these good seedlings he brought, and get close.

It's time for the ...... No, it's time to be reasonable, Lu Zhi cleared his throat, a little happy.

"Hehe, let's take a look here, this is called a blood trough, in addition to bloodletting, it is more important to facilitate the next move."

Lu Zhi made a stabbing action, "When it pierces into the human body, the blood will be discharged with the blood trough, and at this time, the muscles of the injured person will contract violently.

But because it is triangular, the muscles are squeezed from both sides and can never be attached to the knife surface, so it will not be easily 'sucked'. ”

It was a little difficult for the sappers to understand, but Xiao Xinzi was babbling, this situation was familiar to him, it was very common.

Lu Zhi smiled and motioned to Lu Xin to be quieter, "Hey, so that after we stab once, we can pull it out very calmly, and then move on to the next step, poke it again, pull it out, and stab it again...... Until the enemy dies.

Imagine that if there is no blood tank, because of the violent contraction of blood pressure and muscles, the dagger will be 'wrapped' in the flesh and cannot be pulled out, which will affect the next action.

Haha, I believe that no one wants to waste time by drawing a knife. ”

The sappers laughed as well, in fact, still confused.

Things like blood pressure, muscle contractions, these things are a bit out of the ordinary for them.

At present, they still don't have the ability to draw inferences from Lu Youshou, and their insight is far behind.

Lu Zhi raised his eyebrows, looked at Lu Youshou, and said bluntly, "Foreman Lu, these seedlings you selected are not very good." ”

The sappers stopped laughing at once, they all fell silent, depressed, and the blow was not good.

Lu Youshou smiled, "Master Junma, their minds are still good, but they are too young and lack experience and insight. ”

"Haha, that's what I said." Lu Zhiyi raised his head and pointed at the sappers, "You are not me after all, a genius craftsman like this county horse is rare after all,

Perhaps, there will be no more in the whole world! ”
