No change

Ou Chou had been waiting for Xiong Jing to come for a long time, but before Xiong Jing arrived, there was another person who came to Jutie Mansion from time to time in the past few days. Every time he came, Ou Chou felt awkward when he called him. Call the prince a fierce prince, the king is no longer the king, and the prince will not be arrogant; If you don't call yourself a prince, what kind of title can you use to reflect the dignity of the other party?

Fortunately, Xiong Han didn't care about Ou Chou's tangled things at all. Whether you are noble or not, you have to rely on yourself to fight on the battlefield, not on the shadow of your ancestors. Since he heard that Empress Ao had also killed two Qin soldiers, Xiong Han, who was seven feet six feet tall, couldn't bear it anymore, and he begged Concubine Li to give him money to order a set of armor and a sword in Jutie Mansion, and then he came to Jutie Mansion. At this time, the armor was made, and he put on the armor under the service of the servants, and drew his sword, which could not help but be a little complacent. I heard that Xiong Jing also came to Jutie Mansion, and hurriedly rushed out of the mansion.

"Brother Chen, I've seen Da Ao." Probably wanting his brother to see his appearance in huge armor, Xiong Hao shouted loudly, and also performed a new military salute.

"Is that you?" Xiong Jing was a little surprised to see him, and even more surprised to see him wearing a giant armor and holding a huge sword. "Why are you here? Skipping school again and not going to school? You bear cub! Someone's coming......"

Xiong Han has been transferred from the Lantai Academy to the military academy, of course, he is young, and he entered the military academy last year. It is difficult for the children who came out of the palace to endure the hardships of the military school, so they naturally excused themselves from school under the banner of the queen mother.

"Brother Wang is mistaken, mistaken!" Xiong Han hurriedly explained, "The military academy has been evacuated to Xinying, and there is no need for classes. ”

The younger brother didn't say that Xiong Jing really forgot that the military school, aviation school, and witch school were all within the first batch of evacuation plans, and they had already moved to Xinying. Relieved, Xiong Jing said again: "Then why don't you board the boat and go to Penglai?" ”

"The queen mother has not arrived in Penglai, how can the mother and brother go to Penglai first?" Xiong Han pulled his face and was scared by his brother and sweated.

The younger brother mentioned his mother and reminded Xiong Jing of tonight's **, and then his tone slowed down, and said, "Then why are you here?" ”

"Yu Da Ao, Fierce, Fierce Ao and then order a huge armor and a huge sword here, so, therefore, ......" Ou Chou held out a 'Fierce Ao', which made Xiong Han laugh happily. He also wanted to be an Ao, but not like that.

"How old are you?" Xiong Jing did not correct Ou Chou, but looked at his younger brother from head to toe. The younger brother is younger than him, so he is naturally shorter than him, and his face is like Concubine Li's and melon seed face. Both are the children of their father, and the eyebrows, eyes, nose and mouth of the two brothers look very similar, like an identical flat portrait pasted on different shapes of heads, and the difference in physiognomy is mainly the difference in skulls.

At the age when I started to love beauty, I could only see the marks of pimples on my forehead, red and red, which should have just been squeezed by my hands. The eyebrows are delicate, and the eyes under the eyebrows are shining with the unique lively brilliance of a young man. The fluff under the bridge of the nose is also gradually thickening, and a few whiskers are like weeds under the rammed earth wall in the spring, quietly poking their heads out.

Because of the melon seed face, the younger brother's mouth is smaller than Xiong Jing's, which also makes the whole face more delicate and less majestic. This is also evidenced by the small collarbone under the jaw and the flat, plate-like chest. Although the shiny and well-fitting armor covers the body, the width and thickness of the armor can still feel the thinness of the entire body. However, the height of seven feet and six inches is already higher than that of most Chu soldiers, and the nutrition of the palace is better than that of most people.

Seeing Xiong Jing looking at himself, Xiong Han hurriedly straightened up and puffed up his chest. Xiong Jing looked at him and slapped him on the chest unexpectedly, and he suddenly couldn't stand still and took several steps back. The young man was always unconvinced, and he said, "Brother is unprepared, come again." ”

"Unprepared?" Xiong Jing smiled. "On the battlefield, defeat is defeat, how can there be a return."

"I'm seven feet six inches!" Xiong Han ordered the huge armor and sword to go to the battlefield, and he had already thought about it, so he would be his brother's guard knight.

"Seven feet six feet?!" Xiong Jing pretended to be surprised, and waited for a smile to appear on his younger brother's face before he lowered his face and said, "What's the use of standing unsteadily?" You bear cub went to Xinying earlier to serve the queen mother, your mother and sister-in-law, go and go. ”

"Brother Wang, Brother Wang!" The hopeless bear was in a hurry, "I can kill the enemy!" I can really kill enemies! ”

"Well, in a few years, you will indeed be able to kill the enemy." Xiong Jing nodded, he had already gone to the mansion, and his younger brother wanted to follow, but was immediately stopped by the guards.

"Ao Ao is eager to fight." Ou Chou saw that Xiong Jing blocked his younger brother outside the house, and couldn't help but help him speak.

"He's only sixteen, so how can he kill the enemy." Xiong Jing doesn't speak through his brain, at the age of the common people, this kind of height, he has long been recruited by the county and added to the division and brigade. "Where is the nickel armor that Ou Qing said?"

Xiong Jing asked about the nickel armor. He took the word nickel, and when he saw that red copper and another unknown white metal were smelted from the silver-like metal, and then he heard that this silver came from the Dian Kingdom, he naturally thought of white copper. Cupronickel is white because it contains nickel, and the unknown white metal that is refined is nickel.

With nickel, you want chromium. But nickel is all by luck, according to the periodic table to know the world of the middle school students use water and fire as tools to distinguish all things, white copper thrown into the fire, copper melted, so with nickel chromium can not be so lucky, this inevitably makes Xiong Jing regret, if there is chromium, he can make better tool steel, stronger artillery.

Ou Chou waited for Xiong Jing to come to the nickel armor, he quickly brought Xiong Jing into the quiet courtyard used for quenching, and as soon as Xiong Jing sat down, someone gave him a piece of giant armor half a foot wide. The nail piece looks no different from the ordinary giant nail piece, but when Xiong Jing picked it up and looked at it closely, he found that it was whiter than the ordinary giant nail piece, and it seemed to be harder, and it was more laborious to bend the nail piece at both ends.

"What's the difference?" Xiong Jing couldn't make a judgment based on his feelings, and his feelings were inaccurate.

"This ......" Ou Chou waited for many days with a suffocated stomach, and when he was about to speak, he couldn't say it again, he could only say: "Please Da Ao move to the martial arts field in the courtyard." ”

The martial arts field is in the courtyard, heat treatment is the core technology of Jutiefu, and the heat treatment of different methods and temperatures must be tested. In the martial arts field, the piece that Ou Chou showed Xiong Jing was actually tied to a tree-shaped target. When Xiong Jing looked at the crossbow on the opposite side of the target, a craftsman came up, and Ou Chou said: "This is the chief spear of the Qin people, intact, please take a look." ”

"Good." The cavalry of the Qin army used iron swords, and the soldiers used iron spears. The iron spear does not pay attention to toughness, but only stresses the hardness, so the yield is higher than that of the iron sword. However, the Shaofu of the Qin State does not have a tempering process, the spearhead is hard, but brittle, and it will collapse no matter how much it is used.

The chieftain is intact, indicating that the chieftain has not been used. It was supposed to be a weapon captured in the Battle of Shashui. After Xiong Jing saw it, the craftsman who tried the spear did not test the spear against the target by thousands of times, but retreated more than ten meters, ready to rush the spear. Xiong Jing was a little surprised, because the riding spear had to let go after being stabbed, the momentum was much smaller than that of the infantry rushing spear, and according to the research of the combat master Cao, the infantry rushing spear was only weaker than the Jing crossbow.

Since it is a test spear, there must always be a test spear, but the craftsman holding the chief spear does the work of Qin pawns rushing the spear, aiming at the target and rushing forward. With a 'quack' sound, the spear broke on the spot, and only one of his hands was broken.

"Da Ao, please see." The spear was broken, the armor on the target was not pierced, and there was only one mark on it.

"How can you?" Xiong Jing was surprised. He remembered the kinetic energy formula, the speed of a person rushing a spear at a hundred meters could not be ten seconds, but twenty seconds was always there. That is to say, the speed is at least five meters per second, a person counts sixty kilograms, the kinetic energy is at least seven hundred and fifty joules, and a reduction of half is enough to break the armor, how can it not be broken?

"How's the arrow?" Xiong Jing was surprised and asked again.

"Except for the crossbow, nothing is broken." Ou Chou said, and also stretched out his finger and pointed to the thorn crossbow on the opposite side, which was more than a foot high, and it was the thorn crossbow used to test the armor.

"Letter!" Xiong Jing subconsciously shook his head. The power of the crossbow is extremely great, a kilogram of arrows can shoot three or four hundred meters, and the kinetic energy is as high as thousands of joules, how can it not shoot armor-piercing pieces, he doesn't believe it at all.

"Yes!" Ou Chou emphasized. "Fu Xin, please give it a try."

Xiong Jing hadn't agreed yet, and at Ou Chou's signal, the craftsman had already come to turn the ratchet and wind the crossbow. As he had told him before, the tree target moved a hundred paces away, and then aimed at the target and began to test fire. It was still a little difficult to shoot a piece of armor that was four feet long and half a foot wide from a hundred paces away, and only after shooting more than ten arrows did one arrow reach the edge of the armor.

The crossbow was accurate, and the next arrow hit the target, and a craftsman rushed forward to take off the armor piece and offered it, but it was really unbroken.

"Why? Why not break? The nail slice was only shot out of a deep circular depression, and Xiong Jing asked urgently as he touched the place.

"The minister thought," Ou Chou was also puzzled by this, but he knew that it was only now a little clear. He picked up the crossbow arrow and asked Xiong Jing to take a closer look: "The armor is hard and the arrow is soft, so it is not broken." ”

"Ahh Yasoft? Xiong Jing looked at the arrow he offered, and the tip of the arrow was no longer sharp, but flattened. Can ......"

Xiong Jing didn't know what to say. How can an armor-piercing arrow be soft? It took several years to make the armor-piercing arrowheads, constantly adjusting the carbon content of the arrowheads, constantly quenching and tempering, and the armor-piercing arrows were never flattened like soft iron. Where is this arrow is too soft, this is obviously the armor is too hard! Xiong Jing looked at the nail that was shot out with a deep concave. "Hardness geometry?" He asked.

"I don't know." Ou Chou shook his head, "The nickel knife made before is not the same." ”

"Diamond tried?" Xiong Jing asked again.

"I haven't tried it." Jutiefu is accustomed to using high-speed steel to test hardness, rather than diamond from other regions.

"How can I get copper again?" Xiong Jing asked a question that Ou Chou couldn't answer. Previously, he had not thought about the power of the new armor, and only after seeing it with his own eyes did he know that wearing this armor was not afraid of any weapon attack from the Qin people except for the crossbow. In that case, why not build hundreds or thousands of sets? There are hundreds of such armors, and no matter how many cavalry the Qin army has, they can't hurt the cavalry in the slightest.
