"Well, it's almost done now. Now wait until all the materials are completely melted, and then apply the melt evenly on the blade to let the melt penetrate into the blade." Old Man Duan said with a squinted eye. Ling Li ignored him and used the casting stone to carve the shape of the flying knife and made the mold.

"What are you doing?" Lao Duan asked after taking a sip of wine.

"I feel that this material is rich, so it's a pity to throw it away. I will add some fine iron to it later and cast a few flying knives."

"What a fucking money-lover."

"What do you know?" Ling Li made a gesture of contempt, "Save is glorious, waste is shameful!"

"This is very reasonable. How did you think of it?" Old Man Duan was stunned. "I think it's appropriate to hang these two sentences on the wall of the classroom of the Manufacturing Academy every year, so that the students can recite silently every day and keep it in mind at all times."

There is nothing to do now, so the raw materials can only be completely melted, so the two of them returned to the hall and used the stove to make Korean iron plate barbecue. While explaining the details of upgrading weapons, they drank the other jar of old wine. The sorghum wine has a low alcohol content, but it has a lot of energy, and Ling Li feels a little dizzy.

After more than two hours, all the materials in the furnace were melted. Looking from the furnace door, the whole was in a golden liquid state, emitting a hot light.

According to Duan Wuya's instructions, Ling Li first clamped the forged long knife with tongs, then opened the outlet and scooped out a large spoon of hot melt with a spoon. Then he pointed his right finger and the golden liquid in the spoon was applied very evenly on the surface of the forged red long knife. As Ling Li controlled his mental power and continued to apply and temper the scooped out melt, the surface of the narrow and thin long knife gradually covered with golden red melt.

With Ling Li shouting lightly, a powerful wave of mental power surged out of his seal hall, wrapped the sword in, and began to pressurize.

Under the envelopment of his mental power, the metal melt also turned into thousands of threads and slowly penetrated into the blade body, changing the countless subtle structures in the blade alloy. This is an extremely complex infiltration process, and only a spiritual master with sufficiently strong mental power can achieve such subtle operation and control.

Buzz...

Under the pressure of powerful mental power, as these metal melt penetrated into the long sword, the original metal balance attributes in it seemed to be broken, and the blade was trembling violently, making waves of beeping sounds.

"Get me in fusion!"

Ling Li continued to pressurize, and the spiritual power wrapped around the surface of the sword strengthened again.

laugh!

As his mental power compressed again, the metal melt on the surface of the long sword was directly pressed into the blade by a powerful pressure, and was forcibly combined with the original metal.

"This is the pressurized infiltration process of advanced alloys. As long as the mental power is strong enough and the pressure is applied enough, the weapons produced are much more powerful than those created by industrial smelting methods. Pressurized infiltration in the metallurgical industry cannot achieve such fine control." Ling Li was operating with all his strength, and Duan Wuya explained leisurely on the side.

The entire tempering took place several times until the blade body was saturated and no longer absorbed the melt. Then he stopped and placed the cast blade embryo on the anvil. At this time, the dark red light on the surface of the blade body flashed, as if it was active.

The iron should be while it is hot!

Ling Li did not stop. With a thought, a metal heavy hammer appeared out of thin air in his right hand. He fucked the tongs, clamped the still red blade, swung the heavy hammer, and began to forge it continuously.

Forging is the last step of refining the weapon and the most laborious step. The entire step is divided into three parts: coarse forging, fine forging and grinding. After four hours, when the last step of forging the long sword and ten flying knives was completed, Ling Li was completely relieved.

Put the long sword and ten forged flying knives back into the furnace for burning, and the last step of array pattern is to be portrayed. Only after completing the portray of the source force array pattern and the blade releases the source force blade after injecting the source force, will it be considered that the task is completed.

This is his first advanced weapon, and he naturally worked very hard and careful during the production process.

It was a whole night, early the next morning, when the sun rose, Ling Li was finally finished.

The knife is three feet long, the blade is narrow and thin, slightly curved, like the saber style of later generations, the horse's back is thicker, with neat fish scale patterns forged. Touching the blade, the originally dazzling luster on the surface has disappeared under the forging of Lingli, and the entire blade is covered with dark red patterns.

Ling Li showed the blade body that had not yet been installed to Old Man Duan, "A good knife, it is indeed a good knife!" The old guy stroked the blade body with his fingers, and Haoming stroked the girl's body, looking dirty, "I can't bear to give it to you."

"Tsk!" Ling Li snatched the long knife, "Is this knife related to you?"

"Without my guidance, you can create this knife?!" Old Man Duan was furious.

"Hehe, that's not sure." Ling Li smiled shamelessly, "Besides, your advice when refining the weapon was exchanged for two jars of old wine and a large bag of braised dishes. The reward has been paid, and our master and apprentice have been considered to be cleared."

Old Man Duan almost fainted from anger. He had seen shameless people, but he had never seen such shameless people.

"Look, why don't you speak? You're too rude..."

"Get out!" The old guy finally squeezed out a word from his teeth.

This upgrade of the battle knife is actually not too difficult, but it is not that easy to refine the green bow.

The process of upgrading the battle bow is very complicated. The inner bones of this bow arm alloy must be melted and penetrated with rare earth metal crystals in the number, and the array pattern is re-carved inside. Then, the outside needs to be pasted with monster horns of more than sixth level, beast blood, animal glue, etc. It is said that in ancient times, the ancient bow god Tang Xu made a bow, using purple nanlong bamboo as the core, Kui Niu horn as the horn, and infiltrated with black gold, the ridge of the green dragon as the string, the white tiger's teeth as the cluster, and the vermilion bird's feather as the feather. The magic bow made is called the God-killing Bow, which can be called the world's number one magic bow.

The dragon tendons have to be peeled into thin filaments, soaked in high-level animal blood for several days, then kneaded with alloy wires and weaved into bowstrings. After that, it is necessary to penetrate with high-level alloys, and then the array pattern is carved on the surface.

In addition, arrows must be made of high-level alloys and high-level animal bones.

"Well, cut the animal horn into thin slices and wrap the alloy bow bones. This is the method of making a composite bow." Ling Li nodded and said.

Old Man Duan looked for granted, "All good bows are made of composite materials. This natural material always has various defects and must be processed through various processes to make up for it."

It seems that it is impossible to upgrade the Green Owl Bow in a short period of time.

Old Man Duan is indeed unique in manual refining.

Under his guidance, Ling Li first soaked the dragon tendon with the blood of the dragon snake. After a few days, he forged it into a sheet, then tear it into even thin threads with his hands, then melted and penetrated the iridium with real fire, and then weaved it together. In this way, a pair of bowstrings were completed.
Chapter completed!
