Iron smelting is completely different from copper smelting. As long as copper smelting is "spunishing Fan Zheng, Jin Ximei, skillful craftsmanship, and fire together", it can "dissect and moth" and "moye" are all. I don't care about iron smelting. Gold smelting depends on the ore itself, not manual preparation. Without coke or hot blowing, it is difficult to reach the temperature of melting the iron. Working smelting is indeed skillful, but copper smelting is just the ratio between copper and tin, the design and production of mud molds, and the grasp of the heat during casting. Iron smelting is not only forging and carburizing, but more importantly, the heat treatment process under different raw materials and different raw materials.

Low carbon, medium carbon, high carbon; quenching, tempering, annealing; phosphorus, sulfur, silicon, manganese, oxygen; nickel, chromium, molybdenum, vanadium, titanium... The variable factors contained in iron smelting exceed 100 times more than copper smelting. These variable factors interact with each other, and the evolved formula and heat treatment scheme far exceed the experience memory of a single craftsman.

Craftsmen can find one or several of the successful solutions, but only this is limited to this. When certain conditions, such as the environmental temperature changes, hot or cold brittleness occurs, they will be collectively caught blindly. It can be said that before the birth of experimental science, a new witchcraft system that explains the world and studies the world, the witchcraft 1.0 and witchcraft 2.0 systems could not truly master iron smelting. All they could master was to rely on continuous trial and error to obtain the path to success.

Xiong Jing gave some important components of the witchcraft 3.0 system of the Making House: coke and hot blowing have increased the temperature limit that the original system can reach. He roughly followed the periodic table of elements that gushed out further to further understand and subdivided the world's matter based on the witchcraft 1.0 gold, wood, water, fire and earth. He knew what the heat treatment process included, what elements were harmful to iron smelting, and which elements were beneficial to iron smelting...

Even so, without enough time, the Zaofu could not use this incomplete new system to accumulate necessary data for iron smelting. Without enough data accumulation, some unexpected disasters would inevitably occur. At this time, no one in the curtain thought of the disaster. Looking at the inferior chief spear made by the Qin Shaofu on Muji, they couldn't help laughing.

"The Qin people wanted to defeat me with this spear, hahaha..." Xiang Liang was too young, and his laughter was the most unrestrained, making the old men such as Xiong Jing, Dongye Gu, and Ele feel a little harsh.

"The Qin people only have such chief spears, and our army will win!" Ruo Ao Duxing also whispered, his eyes full of murderous intent.

"Can the chief spear break the armor?" Xiong Jing's mind was also filled with blood, his eyes were a little red, but he finally maintained the king's calmness.

"The shogunate has tried, and you cannot break the armor even if you rush to the spear." Zhuang Wudi just went to the shogunate, and the shogunate counselors have tested these weapons.

"Good!" Xiong Jing's body shook and finally shouted.

He understood that the reason why the Qin army could support it to this day was all due to seizure. Seizing the Zhao people's Giant Iron Armor, seizing the Qi people's Giant Iron Armor, seizing the Wei people's Giant Iron Armor, and then robbing more than 20,000 sets of soldiers sold to Bactrice. Once these soldiers were seized by the Chu army, the Qin army would have no useful soldiers. Under the guidance of the craftsmen of Yan State, it was easy to smelter and carburizing and forging, but heat treatment required enough experience. The cracked chief spear in front of him was a manifestation of the lack of experience in Shaofu craftsmen.

"Since the Qin people have no military armor, tomorrow it will be severely snowed, our army should also attack the sand sea quickly and kill Wang Jian." Xiang Yan was killed by Wang Jian, and he couldn't wait to revenge Xiang Liang. He even wanted to break into the sand sea now.

"No." Zhuang Wudi, and Peng Zong also opposed it. "A heavy snow overnight, the road to tomorrow will definitely not work. How to fight?"

"Just rush into the camp of the sand sea." Xiang Liang said. "How can the Qin people kill me without armor?"

"How can our army rush into the camp of Shahai in hundreds of thousands of Qin people?" Peng Zong advised. "Our army is not only cavalry, infantry and artillery; not only soldiers, but also baggage soldiers." After Peng Zong persuaded Xiang Liang, he was worried that Xiong Jing would underestimate the enemy by Xiang Liang's influence, and said, "Although our army won, more than ten thousand injured, there are few soldiers who can fight. If the entire army did not advance together, we should not attack the sand sea."

"The Qin people did not have any military armor, but the Qin people had few military armor." Zhuang Wudi said. "The Qin people didn't know the size of the stone casting machine, and there were also Jing crossbows, so they could kill me. If they could wait for the snow, the Qi army would come."

Zhuang Wudi has been obsessed with the people who are always close to each other. It is the second day, and Qi people are only one day away from opening the seal. After the heavy snow, Muze is completely frozen. Two days, Qi people can reach the sea of ​​sand in a maximum of three days.

"Brother Da Ao, the Zhao army can come!" A voice outside the curtain. With the wind and snow, Lian Yu and a person covered in snowflakes walked in. This was a Zhao general who followed Zhao Han into Daliang City last night. He stepped forward to salute, and then neighed and reported: "Brother, the lord, the lord, has regained the northern city with General Sima. Our Zhao army still has 2,000,000 people, and can fight the Qin people!"

"Good!" Xiong Jing was overjoyed when he heard that there were still 12,000 Zhao troops.

"The people of Zhao fight with me, how can I not fight with me?!" Xinling Jun Wei Jian was worried that when he heard the great victory of the Chu army, he hurried over to celebrate. Just now in the snow, his carriage was chasing Lian Yu's carriage. Seeing his words, everyone was a little confused, and he said again: "I would like to enter the city tonight to talk about the widow."

"You enter the city tonight..." Everyone should not have doubted Xinlingjun's words, but now the outer city of Daliang is all in the hands of the Qin army.

"The Qin general guarding the city is a Wei person, and I have kindness to him." Wei Jianyou explained roughly. "I really don't know... what should the Wei army leave the city?"

"The Wei army left the city..." The Zhao and Wei army were naturally beneficial to the war. Zhuang Wudi quickly spoke, but Xiong Jing stopped him. "The Wei army is only more than 10,000, and he does not defend the royal city and country after leaving the city. Will the King of Wei?"

"It's not a wish, but it's a must." Wei Jian said with worries. "If this battle cannot be won, the Wei State will also be destroyed. If this battle is won, what if the royal city is lost? The Wei State was captured by the Qin people, and the victory can be restored."

"But." Wei Jianyou said something that was reasonable. Xiong Jing looked at Zhuang Wudi and nodded at him.

"The sky is clear and will attack the sand sea." Zhuang Wudi saw Xiong Jing agreeing, and immediately said. "If there is no snow, the gardens can be removed in the royal city to make snowboards and sleds."

"Snowboard and sled?" Wei Jianyou didn't know what this was, until Zhuang Wudi found a real example. "The snowboard is three or four inches wide, and the person is taller and half a foot tall. He slid it upwards with fire in front and back, so that it can be raised. The clogs are firmly on the board, and when walking, they slide with long poles on the left and right, which can last dozens of miles a day. Sledding is the same as the sled, using a board instead of wheels, and sliding on the snow."

Skis and sleds are both improved means of transportation during heavy snow. Xiang Liang, who was determined to attack the sand sea, saw these two things and suddenly thought that Peng Zongzhuang had no way to oppose himself just now. He pondered and had not spoken yet. Zhuang Wudi, who guessed that his mind, smiled and said, "Our army only has sleds and few snowboards. Even if we order the seal to make snowboards today, it will take more than ten days to have 100,000 pairs of snowboards to be available."

"Within three days, the royal city can make more than 10,000 snowboards to fight." Wei Jianyou didn't know why Zhuang Wudi talked to Xiang Liang, so he only promised that the Wei army would inevitably join the war. "I left."

"I also bid farewell." Lian Yu saw the snowboard and wanted to leave. At that time, the snow was enough and could not walk, and the Zhao army also needed such things to leave the city. "There are still craftsmen in the north city. I can ask people to tear down houses and make more snowboards for the use of the Chu army."

"Great kindness!" Qifeng craftsmen have it, but they do not have the wood needed for more than 100,000 pairs of snowboards. If Daliang Beicheng could build 100,000 pairs of snowboards within three or four days, the coalition forces could attack the sea of ​​sand without waiting for the snow to stop.

Wei Jianyou and Lian Yu retreated. They never expected that in the last battle with the Qin people, the generals of the four countries, could still be led by Sima, with a smile on their faces. They were so happy that they had forgotten that there were more than 10,000 merchants in the Qi army, and these merchants could not join the army to participate in the war.

Ten thousand Zhao army, more than 10,000 Wei army - Wei Jianyou If Wei can really convince the King of Wei to send troops, the Wei army will not be less than 15,000, 50,000 Qi army, plus 100,000 Chu army, the number of people is close to 180,000. The number of Qin army is only more than twice, and the width of the array will increase greatly during the battle, reaching 4,000 rows. The Qin army array will also increase accordingly, and the width of the array will become 4,500 rows or even 5,000 rows. Even for 4,500 rows, the array width is only 100 rows, which is no different from the depth of the Wang Ben array that he just defeated.

On the north bank of the gulf with wind and snow, the Chu army general led his army to see the dawn of victory in the dark night. With the same night, the Qin army generals from the Sand Sea Camp led their strategists to see despair.

Without Bai Lin captured the King of Wei City, it was naturally impossible to seize the military armor in the Wei Armory. Without enough military armor, he would probably repeat Wang Ben's mistakes when facing the Chu army and be defeated by the Chu army.

In addition to the armor, there are also problems with the tactics. The Chu army rushed to the spear, and the Qin army could only stand up straight and wait for the stabbing. Can it retaliate? It cannot.

The Chu army array was originally unfolded parallel, and after fighting, it quickly evolved into a zigzag-shaped inverted "公公" shape. Some spear arrays held against their own arrays, while some spear arrays started to rush into spears at some distances from their own arrays. The part that was held against the Chu army was entangled with spears, and they could not rush into spears, but could push the spears; the part that was not held against the Chu army was either a spear array that rushed into spears or an open space in front.

The soldiers of the army cannot abandon the array they are in and move forward. If there is an open space in front, they will be attacked by the Chu army spear formations on both sides; if there is a Chu army spear formation that is rushing to the spear, the Qin soldiers who have not been fully trained to rush to the spear will only be killed by the Chu soldiers. This is equivalent to helping the Chu army. They originally had to run to the end to rush to the Qin soldiers and then retreat, but now they are sent forward to let the Chu soldiers rush to kill, so that they can run half of the distance. After all, the Qin army array cannot be broken, and the soldiers must always be in line with the left and right.

Wang Jian’s hope is the catapult behind the formation, which may be a solution. But we must not forget that the Chu army also seized this catapult after this battle. If the Chu army used this catapult to shoot witch medicine, the distance between the Qin army’s military formation would be more than 150 steps.
