Zheng Qiu obeyed Li Qing's order, selected soldiers with a strength of 300, chose a secluded place in Yanmen Pass, made a craftsman's furnace, and put all the weapons captured from Loulan into the furnace and re-smelted them.

"Quick, speed up."

Zheng Qiu had already stripped off his shirt and commanded some Mo disciples to refine arrow clusters, although the weapons of these Loulan people were not very good, but the materials were not bad, and they were very suitable for building arrow clusters.

"Ding Ding Dong"

The disciples of the Mo family were pounding, and the arrows were formed in their hands, and not far from them, the soldiers of the Qin army were making arrow shafts, and the material they chose was willow trees, which were full of toughness, and were one of the main materials used by the Qin army to make arrow shafts.

Li Qing took Zhang Hu to the production workshop, looking at the people who were working in full swing, Li Qing nodded with satisfaction, picked up an arrow shaft that had been baked, folded it, and felt very good, no worse than Qin Jun's original arrow shaft.

"General, everything is going well, the first batch of arrows will probably be completed tomorrow evening."

When Zheng Qiu saw Li Qing coming, he hurriedly greeted him and said excitedly.

Li Qing asked, "Zheng Qiu, what problems are you encountering now?" Just ask, if I can solve it for you, I will try to solve it. ”

Zheng Qiu smiled innocently and said, "Don't worry, general, there is no problem." ”

Seeing that Zheng Qiu was so determined, Li Qing breathed a sigh of relief in his heart, with this batch of arrows, Li Qing was more sure of guarding Yanmen Pass.

"Bell"

A cluster of arrows flew out of the craftsman's platform and flew straight towards Li Qing, Zhang Hu was furious when he saw this, and hurriedly blocked Li Qing with his body.

"Poof"

Zheng Qiu raised his hand and blocked the cluster of arrows with his arm, and suddenly, Zheng Qiu's arm was bloody.

Seeing this, the disciple of the Mo family who had sent the arrow cluster away by mistake changed his face greatly, and hurriedly came to Zheng Qiu, and said in a panic: "Master, are you okay?" I...... I ......"

Zheng Qiu didn't care about blaming his disciple, worried that Li Qing would be surprised, Zheng Qiu hurriedly said to Li Qing: "Don't blame the general, my apprentice is still young and his skills are not perfect, which disturbed the general, and asked the general to spare him once." ”

Li Qing looked at the injured Zheng Qiu, frowned, took out the golden medicine from his arms, and asked Zheng Qiu to stretch out his arm.

Zheng Qiu stretched out his arm, and Li Qing found that one-third of the arrow cluster had entered Zheng Qiu's arm, because the arrow cluster had just been taken out of the furnace, there was still a high heat on it, and after entering Zheng Qiu's arm, it played a role in stopping the bleeding for Zheng Qiu's wound, but because there were barbs on the arrow cluster, if you want to pull out the arrow cluster, it will inevitably tear Zheng Qiu's wound.

"Bear with me."

Li Qing said to Zheng Qiu, Zheng Qiu nodded, Li Qing suddenly looked behind Zheng Qiu, his eyes revealed surprise, Zheng Qiu saw this, he couldn't help but turn his head in confusion, and at this time, Li Qing quickly put his hand on the arrow cluster and pulled it out hard.

"Ah~"

Zheng Qiu let out a miserable scream, Li Qing took advantage of the fact that the blood had not yet gushed out in large quantities, and poured the golden medicine on Zheng Qiu's wound, the golden medicine researched by Zhu Ying had a strong hemostatic effect, and soon, the blood on Zheng Qiu's arm stopped at a speed visible to the naked eye.

"Good medicine."

Zheng Qiu didn't care about the pain, and looked at the golden medicine in Li Qing's hand with a look of surprise.

Li Qing had long been very clear about the effect of the Golden Creation Medicine, so this time he sent Xue Liang back to the Medicine Mountain, in addition to summoning the disciples of the medical family to come to help in the battle, he also collected the medicinal materials for refining the Golden Creation Medicine and used it to make the Golden Creation Medicine, otherwise there would be no way to treat too many wounded soldiers with just a few bottles of the Golden Creation Medicine on Li Qing's body.

After comforting the Mo family disciple who had made a mistake, Li Qing looked at the bloody arrow cluster in his hand, and suddenly found that the arrow cluster stained by Zheng Qiu's blood actually flashed with a strange cold light, which looked more sharp than the ordinary arrow cluster.

Zheng Qiu seemed to see Li Qing's doubts, and explained: "This is the method of quenching, because the arrow cluster has not completely cooled, and after being contaminated with human blood, the arrow cluster will become harder, this is the blood quenching method studied by Master Ou Yezi, but we northerners have never used this method, because it is too evil." ”

Li Qing nodded knowingly, Li Qing had also heard a lot about the legend of Ou Yezi refining the freshly baked sword with blood, and the legendary famous sword generals and Mo Xie were all sacrificed with the flesh and blood of the swordsmith, and they became famous swords that have been passed down to future generations.

Li Qing said curiously: "Then how did your northern faction refine weapons?" ”

Zheng Qiu said: "We use mountain springs to temper, and the weapons that are refined in this way are not as strong as the weapons that the Southern Sect tempered with flesh and blood, but they seem to be much better. ”

Li Qing nodded, refining weapons with human blood is indeed not orthodox, and suddenly thought of something, Li Qing said: "Can it be tempered with beast blood?" ”

Zheng Qiu shook his head and said, "Although the blood of the beast can also be tempered by weapons, its spirituality is not as good as that of the mountain spring. ”

After listening to Zheng Qiu's words, Li Qing suddenly remembered the forging technology of later generations, Li Qing found that the weapons of the Qin Dynasty were still mainly cast, and the casting was to use the mold to finalize, and then the blade was cut, and the forging knife was to beat the weapon with high intensity and knock out the impurities in the weapon, so that the forged weapon was far stronger in strength than the cast weapon.

Li Qing discussed some of the knowledge he knew about forging and Zheng Qiu, Zheng Qiu's eyes became brighter and brighter, and in the end, Zheng Qiu's whole person became excited.

Zheng Qiu said: "The grace of the general's guidance, Zheng Qiu will never forget, in fact, I wanted to use iron to make weapons a long time ago, but the weapons made of ordinary iron are too fragile and easy to break, but if I follow the forging method that the general said, I can completely build a batch of iron tools, which are compatible with the sharpness of iron and the toughness of bronze, so that the forged weapons will definitely be able to sweep the world." ”

Li Qing didn't expect that he would casually say that he would make iron tools successfully replace bronze tools and become the mainstream weapons on the battlefield, and even let bronze weapons withdraw from the battlefield in advance.

In the Great Snow Mountain, a group of men in white robes are sitting cross-legged in a square carved with huge statues, chanting scriptures in their mouths, their faces full of devotion.

A young man in a white robe pushed open the door, and in the room, there stood a man with a mask on his face, the man was burly, nine feet away, and a pair of eyes were shining with wisdom.

"Sect Master, according to the report from the sect members who infiltrated the Central Plains, the Hundred Sects of the Sons are gathering, and it seems that they want to join forces to fight against the Holy Sect."
