Not changed

Ou Chou had been waiting for Xiong Jing to come, but before Xiong Jing arrived, there was another person coming to Jutie Mansion from time to time these days. Every time he came, Ou Chou felt very awkward when he called him. Just call him a fierce prince, but the king would no longer be the king. Isn’t it a rude to call him a prince? If he doesn’t call him a prince, what title can he use to reflect the other party’s dignity?

Fortunately, Xiong Han didn't care about the matter that Ou Chou was struggling at all. He had to fight on the battlefield by himself, rather than relying on the etiquette of his ancestors. Since he heard that Ao Hou also killed two Qin soldiers and cavalry, Xiong Han, who was seven feet and six feet tall, could no longer help it. He begged Concubine Li to give money to order a set of armor and a sword in Juti Mansion. Then he came to Juti Mansion. At this time, the armor was made, and he put on the armor under the service of his servants and pulled out the sword. He could not help but feel a little satisfied. He heard that Xiong Jing also came to Juti Mansion, and hurriedly rushed out of the mansion.

"I have seen Da Ao." Perhaps I wanted my brother to look at his giant armor, Xiong Han shouted loudly, and a new military salute was fulfilled.

"Is it you?" Xiong Jing was a little surprised to see him, and then he was even more surprised to see him wearing a giant armor and holding a giant sword. "Why are you here? You missed class and didn't go to study? You bear boy! Come..."

Xiong Han has transferred from Lantai Academy to the military academy. Of course, he was young and it was last year for him to enter the military academy. The children who came out of the palace could not endure the hardships of the military academy, so they naturally skipped classes under the banner of the empress dowager.

"Brother Wang has made a mistake, it's a mistake!" Xiong Han quickly explained, "The military academy has avoided Xinying and there is no need to attend classes."

My younger brother didn't say that Xiong Jing really forgot. The military academy, aviation academy, and witch school had moved to Xinying within the first batch of relocation plans. After breathing a sigh of relief, Xiong Jing said again: "Then why don't you board the boat and go to Penglai?"

"Before the mother and queen arrived in Penglai, mother and mother, how could I go to Penglai first?" Xiong Han pulled his face and was frightened by his brother.

The younger brother mentioned his mother again to remind Xiong Jing of the night's **. At this time, his tone slowed down and said, "Then why are you here?"

"By Da Ao, Han, Han Ao has made a giant armored sword here again, so, so..." Ou Chou put out a 'Hao Ao', which made Xiong Han laugh happily. He also wanted to become an Ao, but he was not like this.

"How old are you?" Xiong Jing did not correct Ou Chou, but looked his younger brother from head to toe. The younger brother was younger than him, and naturally shorter than him, with a face similar to Concubine Li and a melon-shaped face. They were both children of the father. The two brothers had very similar eyebrows, eyes, nose and mouth, like a same flat portrait painting on different shapes of heads. The difference in appearance was mainly the difference in the skull.

At the age of beginning to love beauty, only acne marks can be seen on the forehead, red and red, probably just squeezed by hand. The eyebrows are pretty, and the eyes are flashing with the lively brilliance of a young man under the bridge of the nose. The fluff under the bridge of the nose has gradually become dense, and a few beards are like weeds under the rammed earth wall in spring, quietly poking their heads out.

Because of the melon-shaped face, my brother's mouth is smaller than Xiong Jing's, which also makes the whole face look more delicate and majestic. The tiny collarbone under the jaw and the flat chest as flat as a plate also confirm this. Although the shiny and fitting armor covers the body, the width and thickness of the armor can still feel the thinness of the whole body. However, the height of seven feet and six inches is 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 him, Xiong Han quickly stood up and raised his chest. Xiong Jing looked him out of the way and slapped him on his chest. He couldn't stand and took several steps back. The young man was always unwilling to accept it, and he said, "I'm not ready, come again."

"No preparation?" Xiong Jing laughed. "On the battlefield, defeat means defeat, how can you say that you will come again?"

"I'm already seven feet and six inches!" Xiong Han was naturally customizing the Giant Armored Sword to go to the battlefield. He had already decided to be his brother's guard knight.

"Seven feet and six feet?" Xiong Jing pretended to be surprised. When a smile appeared on his younger brother's face, he lowered his face and said, "What's the use of being unable to stand steadily? You, a bear boy, went to Xinying earlier to serve your mother, your mother's concubine and your sister-in-law, go."

"Brother Wang, Brother Wang!" Xiong Han, whose hope was shattered, was anxious, "I can kill the enemy! I can really kill the enemy!"

"Well, I can definitely kill the enemy in a few years." Xiong Jing nodded. He had already walked into the mansion. His younger brother wanted to come with him and was immediately stopped by the guards.

"Han Ao Qiu is eager to fight." Seeing Xiong Jing blocking his younger brother outside the mansion, Ou Chou couldn't help but speak for him.

"He is only sixteen, so how can he kill the enemy?" Xiong Jing was not smart enough to speak. At this age and height of the common people, he had long been recruited by counties and towns and added to the army. "Where is the nickel armor that Ou Qing said?"

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

With nickel, you will want chromium. But nickel comes from luck. Middle school students who understand the world according to the periodic table of elements use water and fire as tools to distinguish everything. White copper is thrown into the fire, and the copper melts. So it is impossible to be so lucky with nickel chromium. This inevitably makes Xiong Jing regret. If there is chromium, he can make better tool steel and stronger cannons.

Ou Chou was waiting for Xiong Jing to come and it was the nickel armor. He quickly took Xiong Jing into the quiet courtyard used for quenching. As soon as Xiong Jing sat down, someone gave him a half-foot-wide armor piece. The armor piece looked no different from ordinary armor piece, but when Xiong Jing picked it up and looked carefully, he found that it was whiter than the ordinary armor piece and seemed to be harder, so it was more laborious to hold the two ends of the armor piece and bend it.

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

"This..." Ou Chou waited for many days, and when he was about to say it, he couldn't say it. He could only say: "Please move to the martial arts field in the courtyard."

The martial arts field is in the yard, and heat treatment is the core technology of Juti Mansion. Different methods, the heat treatment of temperature 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 opposite the target, a craftsman came up. Ou Chou said, "This is the chief spear of the Qin people, it is not intact. Please watch it."

"Good." The Qin cavalry used iron swords, while the soldiers used iron spears. Iron spears did not pay attention to toughness, but only hardness, so the yield rate was higher than that of iron swords. However, the Qin Shaofu did not have a tempering process, and the spearhead was hard, but it was brittle. It would collapse after using it.

The chief spear is intact, which means that the chief spear has never been used. It should be a weapon seized in the Battle of Sand and Water. After Xiong Jing saw it, the craftsman who tested the spear did not test the spear thousands at the target, but retreated more than ten meters to prepare to rush the spear. Xiong Jing was a little surprised. Because he had to let go after stabbing the spear, the momentum was much smaller than that of the infantry's spear. According to the research of the combat officer Cao, the infantry's spear was only weaker than that of the Jing crossbow.

Since it is a spear test, it always looks like a spear test. But the craftsman holding the chief spear does the job of Qin soldiers rushing forward, aiming at the target, and then rushing forward. With a "ga" sound, the spear broke on the spot, and only one broken left in his hand.

"Please look at Da Ao." The chief spear broke, the armor on the target was not pierced, there was only one mark on it.

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

"How about the arrow?" Xiong Jing asked again after being surprised.

"Nothing outside the Jing crossbow is broken." Ou Chou said, and pointed to the Jing crossbow more than ten feet tall opposite. The one used to test armor was the Jing crossbow.

"Don't believe it!" Xiong Jing shook his head subconsciously. The Jing crossbow is extremely powerful. One kilogram of arrows can shoot out three or four hundred meters, and the kinetic energy is as high as thousands of joules. How could he not shoot armor-piercing pieces? He didn't believe it at all.

"That's right!" Ou Chou emphasized. "Don't believe me, please give me a try."

Xiong Jing had not agreed, and at Ou Chou's instructions, the craftsman had already turned the ratchet and skewed the crossbow. As he had reported before, the tree-shaped target moved a hundred steps away, and then aimed at the target to start a test shot. It was still a bit difficult to shoot a piece of four feet long and half a foot wide armor with more than ten arrows. Only after firing more than ten arrows could one arrow hit the edge of the armor.

The Jingbird was accurate and hit the target with the next arrow. A craftsman took off the nail piece before running, and brought it up, but it was really not broken.

"Why? Why not break?" The armor piece was shot out with only a round and deep concave. Xiong Jing touched the place and asked anxiously.

"I think," Ou Chou was puzzled by this, and knew that he was a little clear now. He picked up the crossbow arrow and asked Xiong Jing to look carefully: "The armor is hard but the arrow is soft, so it is not broken."

"Ah! Arrow soft?" Xiong Jing looked at the arrow he offered. The front end of the arrow was no longer sharp and had become flat. "But..."

Xiong Jing didn't know what to say. How could the armor-breaking arrow be soft? It took several years to create the armor-breaking arrow, constantly adjusting the carbon content of the arrow, and constantly quenching and tempering. The armor-breaking arrows made have never been flat like soft iron. This is not because the arrow is too soft, it is obviously because the armor piece is too hard! Xiong Jing looked at a deep concave armor piece shot out as if he had some insight. "How hard is it?" he asked.

"I don't know." Ou Chou shook his head, "The nickel-master knives I made before were not like this."

"Can diamond be tried?" Xiong Jing asked again.

"I haven't tried it." Ju Tiefu is accustomed to using high-speed steel to check hardness, rather than diamonds from outside the world.
