Now junior high school students, are all all-rounders, moral, intellectual, physical, aesthetic and labor all-round development, learn any cram school, Qian Duoduo's sketching skills are very thick, a few simple pencils, just let her remember the appearance of the knife on the paper, moreover, the knife body also has a shadow, 3D effect.

"It's a bit like a cross," I frowned, "the blade is the same length as the hilt?" ”

"That's right," Qian Duoduo said affirmatively, "Mr. Li...... The person said that this is the biggest feature of the Mo knife, not only the length of the blade and the handle, but also the wood used in the handle, but also the weight of the steel used in the blade, to be precise, the handle should be slightly heavier, be sure to make the center of gravity of the whole Mo knife, fall in the palm of the hand before holding the knife. ”

The forehand, I know, is the hand that holds the "handguard" of the sword, a right-handed person, that is, the right hand is in front, and the left-handed person is the opposite.

"Do you remember the length of the knife?" I asked again.

Qian Duoduo nodded, and as he spoke, he marked on the paper: "He told us the data of all parts of the Mo knife, and at that time, I had a little more thought, thinking that if I could escape, I might be able to use it, so I memorized it with my heart." ”

Soon, Qian Duoduo marked the dimensions of each part of the Mo knife, and after I read it, I felt a little surprised, is it so long?

Blade length: 111 cm, handle length 111 cm, blade is straight, double-sided, blade width 3.5 cm, both sides of the blade are parallel, until 5 cm from the tip of the knife, it begins to naturally retract inward, forming a tip that is not very sharp.

Duoduo draws three views, the cross-section of the blade is a diamond, the diagonals are 3.5 cm (that is, the width of the blade), 0.7 cm (that is, the thickness of the blade), the paper looks like it, the thickness is just right, the composition of the diamond is very beautiful, similar to diamonds, I am not good at math, I don't know this design, whether it follows the golden ratio.

Although the math is not good, I can also calculate that the length of the entire Mo knife is 222 centimeters, which is about to catch up with Yao Ming's height, and the fake Mo knife that Qian Dazhuang and I made just now is only 2 meters long.

"With such a long knife, can a person of average height use it?" I can't help but wonder.

"Anyway, he said, this is completely the data of the ancient Mo knife, and the soldiers of the Tang Dynasty used such a long knife, and it was a foot fight." Qian Duoduo naturally doesn't understand the five instruments, she is only responsible for retelling it accurately.

"What about the weight of the knife, is there a requirement?"

"Yes. The blade of the knife weighs 3.4 catties, and the handle of the knife is one or two more than the blade, that is, 3.5 catties. ”

It is 7 pounds in total.

What is the concept of 7 catties? The weight of a baby's newborn! When it comes out, it will be a very heavy knife!

"That's all I can remember, is it easy to make?" Qian Duoduo asked.

"It should be very well made." I said that the machine tools in the factory are numerically controlled, and what kind of knife needs to be made, as long as the relevant data is set, and then the steel is sandwiched in the base, the machine will automatically complete the cutting.

I just finished learning the operation at noon, and I haven't forgotten it yet.

"Oh, by the way," Qian Duoduo reminded, "he also said that the Modao has extremely high requirements for steel, and if it is made of ordinary steel, it must be forged and stacked with more than 1,000 layers. ”

"Girl, we only have a factory, we can only do cutting and grinding, there is no blacksmith shop, forging is definitely not good, there is no such condition." Qian Dazhuang said softly.

"Then you can only work on the steel itself, and you need to use high-hardness synthetic steel." Qian Duoduo said with certainty.

Steel? I remember when I was looking for steel in the factory before, I found a lot of oilcloth bags, some of them were steel bars, some were steel plates, and the oilcloth packaging had labels on them, as well as the English instruction manual, I couldn't understand the instructions, and I didn't know what the letters and numbers of the labels represented.

"Which of you knows industrial English?" I asked the ladies who were gathering under the umbrellas for a drink.

They all shook their heads, and only Su Lingge was looking at me.

"You know?" I asked.

"I don't understand, but I got an IELTS score of 8.5." Su Lingge took a sip of Fanta lightly.

I gave her a blank look: "Just score 8.5, are you embarrassed to show off?" ”

"You old hat," my cousin scolded with a smile, "The full score of the IELTS test is only 9 points, and 8.5 points is already the top level, which is almost one in a million!" ”

"It's not that high," Su Lingge waved his hand, and when everyone's surprised eyes were all focused on her, Ling Ge said faintly, "0.03 percent of people can get 8.5 points." ”

Her forced tone is frustrated, I take it, 0.03 percent, isn't it three out of ten thousand!

"Just you, come with us." I said with a sad face.

My cousin got up: "Tomorrow, it's a little too late." ”

"It's okay," Su Lingge said with a smile, "I don't think our leader, the time should be very long." ”

Even Ye and Dongdong and their cousins understood this pun, covered their mouths and snickered, Xiaoxiao and Qian Duoduo were too simple to understand, Qian Dazhuang should have pretended not to understand, holding a beer, and looking away.

With a black face and a lot of money with a lot of blueprints, I returned to the factory.

Qian Dazhuang and the two of us first studied the new cutting program, entered the data, Su Lingge went to the warehouse to select steel, and soon hugged a long steel plate, saying that it was 1095C high-carbon steel imported by Citigroup, with a carbon content of about 1% and a hardness of up to HRc50, which is the highest hardness among all the steel in the warehouse.

After a while, Dazhuang and I designed a good program to clamp the steel into it, and I could obviously feel that the cutting and milling process was a bit laborious, and many places could not be formed at one time, and the milling cutter was needed to go back and forth, indicating that this piece of steel was indeed much harder than the previous one.

It took half an hour to make the blade, I took it out, and polished it by hand with high-eye sandpaper, it was really different, after polishing, the blade was as thin as a cicada's wings, and the blade was clear and bright, and it could even be used as a mirror to look at the face!

Weighed, the blade of the knife is just 3.4 pounds, in line with the standard.

I took off the handle of the fake before by 111 centimeters and weighed it, no, it's too much worse, less than 2 catties.

"Let's go," said Qian Dazhuang, "when I go back, I'll wrap the belt around the handle of the knife again, it's getting late, we have to go back." ”

"Okay."

The three of them returned to the castle under the cover of Lianye's flight, the sun was sinking in the west, and after dinner, Qian Dazhuang found a black sheepskin jacket, cut the leather coat into thin strips, circled and circled, tightly wrapped around the handle of the knife, wrapped a layer, the weight was still not enough, and he nailed a few iron nails at the end of the handle to increase the weight.

When it was done, I stretched out my index finger, and Qian Dazhuang put the part of the knife in his front hand and gently placed it on my index finger, and the whole long knife, like a static balance, did not move at all!

"You actually made it!" The cousin was surprised, picked up the knife, held it in both hands, and played back and forth twice, "It's not too heavy." ”

"I just don't know how effective it is to fight zombies." I looked at Qian Dazhuang, and it was safer to let him experiment.

"I'll go down and try it!"

It's almost five o'clock, the sun has become very lazy, the zombie's vitality has recovered, Lian Ye flies, covers me and Qian Dazhuang to the horse farm, rides on the horse's ass, as usual, I hold L, he holds a knife, just get on the horse, we were found by an ordinary zombie.

Qian Dazhuang walked towards the zombie unhurriedly, waited until the attack distance, swung the knife and slashed, I felt that he didn't use all his strength, but the effect of the chopping made my jaw almost drop, not only me, the observers in the castle, but also exclaimed, Dongdong hurriedly covered Qian Duoduo's eyes, not letting her see her "scientific research results"!

The body of the zombie is still standing in place, but half of the upper body has slipped off and fell to the side of the right foot, because it did not hurt the brain, it is not dead, the zombie looked up at his body, his expression was puzzled, even if it was not dead, but because it had no lower limbs and an arm, it could no longer move to attack.

I slapped my horse forward and checked the blade, and there were no gaps!

Seeing that there were no corpses left and right, I boldly dismounted, approached the zombie, it roared at me twice, and crawled to my side twice with the remaining small half of its body, but did not find the center of gravity, and fell, I squatted down to observe its body, from the left shoulder, to the right waist, diagonally to a cut, very neat, like luncheon meat cut by a kitchen knife.

"The ancients don't deceive me!" I exclaimed, it turns out that the legendary Mo knife that can make "people and horses shatter" really exists!

Moreover, we use ready-made material steel, if the ancient method of stacking steel is used to further increase the toughness and hardness of the knife, perhaps, the power of this Mo knife will be even more amazing!

"Good ice machine!" Qian Dazhuang slashed, shouted, and rode directly towards the zombie group in front of the castle.

"Hey, wait!" I hurriedly turned over and followed over, and at the same time shouted that Lian Ye and my cousin also flew over, both of them were holding long L's in their hands, and the three of them covered Qian Dazhuang to try the knife together to prevent accidents, the reason why they were so cautious was because there were at least ten second-order zombies in the zombie army in front of the castle......
