"Bang, bang, bang."

In the workshop of the military camp, the craftsmen hammered the freshly baked iron ingots with the hundred refining methods taught by Li Chen.

Daqin's military industry should be one of the best in all dynasties. Advanced assembly line operation method, each craftsman is responsible for the casting of one component. First, proficiency can be guaranteed, and second, all craftsmen will only take their own steps, ensuring the secrecy of the military industry.

The method of refining iron ingots is to make steel by repeatedly folding and forging deformations.

It is characterized by repeated heating and forging. Repeated forging can eliminate inclusions in the steel and reduce the size of residual inclusions, so that its composition tends to be uniform, the structure tends to be dense, the grain is refined, and the properties of iron are improved. The craftsman heats and forges the "fine iron" more than 100 times, one forging, one weighing and one light, until the catties are not reduced, that is, hundreds of steel.

"Bang, bang, bang."

In the blacksmith's hand, the hammer was constantly struck on the iron ingot, and the rudiments of a knife were gradually revealed.

"Your Majesty has arrived."

Just as the two of them were watching intently, as if watching their children come into the world, a shrill voice came out of their ears.

"Meet Your Majesty."

Seeing the black figure walking in, everyone knelt down in unison.

"Get up."

"How's it going?" The First Emperor asked.

"Steel has been refined, just waiting to be crafted." Win the month reached.

"Zi, zi, zi."

At this time, the craftsman first put the long knife into the horse urine and quenched it, there is salt in the urine, and the metal cools quickly, which can ensure the hardness of the steel.

Then the long knife is put into the lard, in the grease, the cooling rate is much slower, which ensures that the metal is not easy to deform and crack, and has good toughness.

"Your Majesty, look."

"This knife is about three feet long, and it is a long and wide knife-shaped weapon, between a large knife and a single knife. When used, hold the hilt of the sword with both hands, and use the weight of the blade and the knife itself to slash the enemy as if it were a broadsword. ”

The craftsman had already finished casting the first knife, and Li Chen handed the knife to the First Emperor and said.

"Boom."

I saw the First Emperor holding a sword in his left hand and a bronze sword in his right. The two intersected, and only a crisp cracking sound was heard, and the bronze sword cracked, but there was not even a gap in the long knife.

"Can this thing be equipped with the whole army?" The First Emperor asked.

"Yes." Li Chen replied that the stock of iron is far greater than that of copper, and there are many open-pit iron ores, which are also easy to collect.

"This knife is equipped with the saddle horse pedal invented by Aiqing, the knife borrows horsepower, and the horse follows the knife, which is really shocking under this split. From then on, my Great Qin cavalry was not afraid of the steppe people. The First Emperor said.

"Your Majesty, please name this knife." As a senior licking dog, stammering leadership is a compulsory course for Li Chen.

"In this case, let's call it Qin Dao." The first emperor said that the Pu Dao of the Great Song Dynasty in the previous life was renamed in this way.

"Whether it's steel or these weapons, it's an immortal achievement, how do you want me to reward you." The First Emperor asked.

"How can you not have both civil and military skills, the iron weapon is my martial arts dedicated to Your Majesty, and it is not too late for me to dedicate my literary skills and reward them together." Li Chen didn't want any credit at this time, and now he was already waiting for Guan Nei, and he was waiting for the same thing as Wang Jian in the last step. And the pace of transforming Daqin by himself is only a small step, and it is not a good result to seal it.

Except for the slave soldiers, which are long-term soldiers, the period of conscription or conscription is basically two years. And in just two years, it was difficult for soldiers to master sword skills. If the army is equipped with long knives, it only needs to train the strength of the soldiers, and master the chopping to form combat effectiveness.

Late at night, Shimen Mountain, Shenwu Army, Chinese Army Camp Tent

"Li Chen, are you a man, why can't you even drink me as a weak woman." Ying Yue was holding a sea bowl, her left foot was on the stool, her waist was straight, and her face was red because of the effect of alcohol, which was brighter than the red leather armor on her body.

"It's not a man, you try." Li Chen looked at the tiger girl and said.

"You dare to tease me, believe it or not, Princess Ben cut off your head."

"Bang."

As soon as Ying Yue finished speaking, the whole person suddenly fell on the table, and the sea bowl fell to the ground and shattered.

Li Chen hurriedly helped Yingyue check his body, but he was fine, but he drank too much and didn't fall out.

An hour ago, in order to celebrate the birth of ironware, Yingyue had to pull Li Chen to drink. I have to say that although she is in the army, as a princess, Yingyue, the food is still quite good.

The imperial chef in the palace is in charge of Yingyue's small kitchen, and this skill naturally needs to be said more. The ingredients are also flying in the sky, running on the ground, swimming in the water, everything.

The food is good, but the wine is much worse. The wine of the Qin Dynasty was still fermented wine, and wheat or millet was used to make koji, which survived fermentation to make liquor. The wine is very cloudy, there will be some residue, and the degree is not high, only about ten degrees at most.

"Do you drink this wine on weekdays?" Li Chen asked. The distilled liquor sold by herself and the Ba family has already flowed into the high-end market of the Qin Kingdom, and Ying Yue, as a princess, has no reason to still drink these turbid liquors.

"I don't drink alcohol on weekdays, I get it from the room." Ying Yue said.

"Sister Yue, Brother Li, come and try this sake." At this moment, Wang Li said with two jars of wine.

"Well, it's so strong, this wine is as clear as spring water."

"The things of the Ba family are really as good as ever."

Ying Yue opened the yellow clay wine seal on the jar and exclaimed.

"Sister Yue, this is not a thing of the Ba family, the boss of this wine is far away in front of you." Wang Li said.

"This wine is yours." Ying Yue was surprised.

"Well, just a little money." Li Chen said.

"Now that we are the aristocratic and rich families of the entire Great Qin, who still drinks that yellow and clear turbid wine, you are afraid that you will make a lot of money." Wang Li said.

"Wang Li, sit down together." Ying Yue said.

"No, Brother Li's field army drill code said that generals should eat, drink and sleep with soldiers." Wang Li put down the wine in his hand and walked out of the tent.

Li Chen's handwritten military manual for the field army has been enshrined as a holy text by Wang Li in the past few days.

"I didn't expect you to be a little beggar who still knows how to do military affairs." Ying Yue laughed and said, she has studied military affairs since she was a child, so she naturally has a deep shade of this. In her opinion, some of the tactics in this field army military manual, such as guerrilla warfare, blitzkrieg, and so on.

Among them, the simple 16-character truth of "the enemy advances and I retreat, the enemy is stationed and disturbs me, the enemy is tired and I fight, and the enemy retreats and I chase" is not inferior to the military book written by her teacher Wei Yizi. Compared to this, this book is more straightforward and easy to understand, as if it was specially prepared for those low-level officers who do not read much.

"Hey, what's the use of you letting Wang Li stand on the stake with the soldiers all day long, and do those shameless actions all day long." Ying Yue asked.

"It's called push-ups, and it's the most effective way to build arm strength and waist strength. When the push-ups are done, the knife can be more powerful. Li Chen said.
