And Nie Hongming, who was standing on the side, couldn't stand it anymore for a long time, and said loudly: "Can you listen to me a few words." In the case of your blueprint, even if you increase the hardness of the steel by a factor of ten, it will not work, because the blueprint itself is problematic. Although I don't read much, I also know that there should be 'three views' and 'analytic equations' in the design drawing. You guys, no!"

When Su Xuan heard this, he thought to himself, the sage said: Sensitive and studious, not ashamed to ask. I'd like to hear what you can say......

The public loser did not speak, just waited quietly.

At this time, Nie Hongming wanted to organize the language, but it was really difficult to explain the principle of gun activation, so he said: "With your knowledge reserves, it is really difficult for me to explain some problems. And gunsmithing, I took a look, and you don't have any tools here. There's no electricity, so make a hairy gun?"

Just as Nie Hongming said, Su Xuan found that it was really difficult for him to understand what this Nie brother was talking about, what firearms, electricity, and electricity had never heard of. "Then tell me, how should I change my design drawings?"

Although Nie Hongming has not read much, he also has a lot of experience in weapons research, and there is such a saying? If you want to do a good job, you must first sharpen your tools. If you want to be the best in the world, you must have enough research on your own weapons.

"Don't think about rifling, you can start with bullets, have you ever thought about it, what will happen if you directly put * in the bullet?" Nie Hongming said, although there is no rifling gun, you can't make the bullet spin, but designing rifling in the barrel is really too affordable for the technological level of Magic Brake City.

As soon as he heard this, Su Xuan was immediately stunned, and put * in the bullet? How can this be done?

Nie Hongming hurriedly took the pen and scratched it on the paper, and explained while drawing: "A bullet is divided into two parts, one is the warhead, the other is the bullet case, we add * to the bullet case, and after adding *, add the bullet to the bullet case. You see, in this way, the enormous pressure created by the * combustion will be counteracted by the cartridge case, and the damage to the barrel will be reduced. Hey, do you understand?"

Su Xuan listened to Nie Hongming's explanation, and his heart was a little shocked, why didn't I think of such a design?

"Brother Nie, are you sure you don't like to read. Your level of knowledge is so profound that you can throw me a few streets...... You know what? Why is your brain so smart?"

Gong Yipan thought for a while and said: "It's a good change, in this way, every time a bullet is fired, the damage is the cartridge case, and the loss of the barrel will be reduced a lot, but it is impractical." We can't make the kind of stuff you're talking about. ”

For a civilization that doesn't even have electricity, it's impossible to ask for weapons and ammunition.

At this time, Nie Hongming looked embarrassed and said, "So, you still don't want to make guns...... Brother Su, it's good that you can think of using it in weapon manufacturing at the first time of your invention, but many people can't think of it......"

Su Xuan thought to himself, this Demon Temple City is full of dangers, and if he doesn't upgrade his weapons, he can only be destroyed. Discovering such a powerful power, of course, was the first time to use it in weapons, otherwise why invent it?

Nie Hongming looked at Su Xuan's frustrated face and comforted, "Brother Su...... This weapon can't be made in a while, I gave you a lot of books in it, covering all major disciplines, you take a look at it first, knowledge is power. You know, if I had been able to study hard as a child, maybe I would have been a scientist by now. ”

"What is a scientist?" asked Su Xuan suspiciously.

Nie Hongming's old face turned red, when he was in school, what he hated the most was the explanation of the nouns, and the quality education that was said to be good, didn't the result be to rely on the back? Faced with such a situation, he could only shift and quietly change the topic, "There are books on them, turn them yourself! By the way, what type of books do you like to read?"

Su Xuan said: "Don't get tired of learning, don't choose the scroll with your hand." (Original sentence: never get tired of learning, never tire of teaching.) From "The Analects of the Analects"), as long as it's a book, I like to read it, but unfortunately there are so few books in the Magic Brake City, I thank you for your gift, thank you for sending knowledge to the Magic Brake City. Saying that, Su Xuan actually knelt down and kowtowed on the spot.

Su Xuan's actions surprised Nie Hongming, and they all said that the man had gold under his knees, how could he kneel to others at will?

"Mr. Su, please hurry up, you are like this, it makes me very uncomfortable!"

"I've never seen so many books in my life. I will read it in the shortest possible time and pass it on to the children. You have brought hope to Mosha. ”

Nie Hongming was shocked in his heart, these books were just not read by himself, he didn't expect that these things that he discarded were so important to Magic Brake City......

"Mr. Su Xuan. "I don't know when it began, Nie Hongming's title to Su Xuan changed from Brother Su to Mr., I'm afraid that even he didn't find out about this, "Mr. Su Xuan, these books are actually nothing, I knew that there was such a shortage of books here, so I bought them in large quantities! I-"

When Nie Hongming said this, he suddenly felt a chill in his back, his heart twitched, and a sense of danger enveloped him. He hurriedly flashed to the side, only to hear a "bang", and a flying knife with a transparent body was deeply inserted into the pillar!

This sudden change made Su Xuan startled, his eyes were fixed on the direction where the flying knife was shooting, and he just wanted to chase it out, but was stopped by Nie Hongming.

"Mr. Su Xuan is slow, the person who came is a master, even I am not sure to deal with it. Nie Hongming pulled out the flying knife inserted in the wooden pillar, and knowledge points came to his mind one by one.

The streamer flying knife, about three inches and three minutes long, is as white as jade, such as a snake, and can take people's heads thousands of miles away.

Nie Hongming's eyes froze, and he thought to himself, the person just now obviously didn't have a killer, if it was a real streamer flying knife, even if it was his own father, he wouldn't dare to pick it up at will. Such a master actually came to Demon Brake City! Is his purpose the same as me, wanting to challenge Master Shuiyun's disciples?

At this time, Su Xuan's heart was beating violently, when did so many masters appear in this magic brake city, each of them was much stronger than himself. The throwing knife just now seemed to have come from a long distance.

"What is the origin of the flying knife?" asked Su Xuan.

However, at this time, Nie Hongming's eyes erupted with earth-shattering battle intent, and he simply turned a deaf ear to Su Xuan's words, at this time, he just wanted to find that master and fight happily! That is a real master......

didn't wait for Su Xuan's reaction, Nie Hongming's immediately chased out!

Su Xuan originally wanted to chase him out, but was stopped by Liu Ruyue.

"Brother Su Xuan, these people are from unknown origins, don't chase them, be careful of deception. There's still a lot of mess to clean up in Magic Brake City. Liu Ruyue said.

"I was reckless...... Let's go, let's go see how the brothers and sisters are preparing......" After Su Xuan finished speaking, he took Liu Ruyue's hand and left the workshop, the latter only struggled slightly, and a blush appeared on his face.

............

On the other side, Nie Hongming hurried to the middle of Wanren Mountain, only to find a man dressed in black, waiting there early.

This person has delicate eyebrows, a tall figure, his hands crossed in front of him, and he is looking at Nie Hongming with a calm face.

"Who are you, why do you attack from behind?" Nie Hongming asked.

"Don't you have any points in your heart when you hold the Streamer Flying Knife?" the man said, "I have long heard that the Human Emperor Sword is the sword of justice of the king of heaven and earth. Today, let's take a look at ...... Is it the Human Emperor Sword that is powerful, or is our Ye family's Streamer Flying Knife powerful?"

After hearing this, Nie Hongming sneered and said, "Are you the strongest in the Ye family?"

"Why are you talking so much nonsense? Don't you want to have a good fight?" After the man finished speaking, the silver light flashed in his hand, and a flying knife shot at Nie Hongming at a very fast speed.

Nie Hongming was not to be outdone, his hands were sealed, and for a while, the human emperor sword that sank into the Qingxi River immediately turned into a silver streamer, and was caught in Nie Hongming's hand in an instant.

The originally slender Human Emperor Sword instantly turned into a three-meter giant sword, blocking in front of Nie Hongming. The body and the giant sword are not coordinated at all, but Nie Hongming, who wields the giant sword, does not feel the slightest discomfort, this giant sword is like a part of his body, it can be controlled and easily controlled...... The action is even smoother, without the slightest sense of stagnation and rustiness.

The black-clothed young man on the side did not stop firing the flying knife for a moment. A flying knife, just like its name, was scattered into the air like a streamer, and then shot towards Nie Hongming, the small flying knife collided violently with the black three-meter giant sword, and the sound of rubbing metal collision was endless, and from time to time there were golden sparks.

Nie Hongming's mind turned wildly, and the book said that to deal with the Ye family's streamer flying knife, you must not try to get close, but I want to see why this is ...... Nie Hongming thought in his heart, and immediately dragged his long sword and rushed towards the man in black.

Seeing this scene, a sneer appeared on the face of the man in black, "Close?" I saw that with a slight touch of his toes, his entire body immediately withdrew from a hundred meters away, leaving only an afterimage that could not be dissipated for a long time in the same place. In the next second, Nie Hongming's Human Emperor Sword immediately slashed at the afterimage!

Nie Hongming looked at the man in black who was a hundred meters away and said, "Is your move a 'light and shadow step'?"

"Count yourself on some knowledge!"

Light and shadow step is one of the Ye family's "three stunts", and legend has it that if you practice to the extreme, you can make your own speed reach the speed of light. "I heard that if you cultivate your Ye family's exercises to the extreme, you can turn yourself into a ray of light, is this true?" Nie Hongming said.

"I want to see how you can crack my light and shadow ......"

Hearing this, Nie Hongming said silently in his heart: Giant Sword Sealing Technique.
