After a brief explanation, Sheng Qingyun hurried to the Casting Division of the Special Operations Bureau, and went straight to Chen Yilong's sword casting room.

As soon as Chen Yilong saw Sheng Qingyun coming, he said excitedly: "Your material has found a way to smelt, you can come and see what you like about sword embryo casting!"

Sheng Qingyun has never seen what a real flying sword looks like, he has a good sword in his hand, that is, the pine pattern Qingfeng sword left by Chixia Danshi, the sword is three feet long, and I don't know how it was cast, more than a thousand years, there is still no rust, out of the sheath like a dragon's chant, the sword body is like a flood of autumn water, the pine pattern is just like the rippling autumn waves, and there is no stagnation in cutting gold and iron; Sheng Qingyun used the sword when he opened the retreat stone chamber in the Eagle Head Cliff, cutting stones is like cutting tofu.

Sheng Qingyun couldn't think of what his first flying sword would look like for a while, so he thought about simply asking Chen Yilong to recommend it.

Chen Yilong didn't bother to say anything about Sheng Qingyun's attitude towards not knowing what kind of sword he needed, and directly asked an apprentice to bring a booklet, which was full of all kinds of sword pictures, which was very exquisite.

Long swords, short swords, narrow swords, broad swords, war swords, swords, eight-sided swords, six-edged swords, serpentine swords, serrated swords, concise, quaint, cool...... There are a lot of dazzling colors, and I don't know how to choose.

In the end, Sheng Qingyun chose an eight-sided sword as the mold of his flying sword, and when making the sword model, Chen Yilong made a slight change to the eight-sided sword model, and then he was satisfied with letting people make a sword model.

Before smelting the mold, Chen Yilong was ready to do further quenching of the material, but this quenching work was not completed in his sword casting room, Chen Yilong led Sheng Qingyun to fly to Shanghai by special plane to the largest shipyard in China.

Following Chen Yilong to the largest shipyard in China, Sheng Qingyun was a little inexplicable, how could the casting of the sword be related to the shipyard.

However, Sheng Qingyun didn't say anything, the sword casting master Chen Lao should know that he followed honestly, and Chen Lao would do whatever he told him to do, as long as the sword embryo could be cast, the rest didn't need to be figured out.

In the end, he followed Chen Yilong to a huge workshop, there is a huge machine standing in the middle of the workshop, it is indeed a huge machine, the factory workers said that it is the largest forging press in China at present, 100,000 tons of hydraulic press, specially designed for large ships to forge all kinds of large decks, hulls, any material under the pressure of 100,000 tons will be easily kneaded like dough, forging into the desired shape; there is also a large furnace next to it, which is specially designed for heating all kinds of special steel, and the furnace temperature limit can be as high as 3,600 degrees Celsius.

With the assistance of the computer, the factory workers did a precise operation of the machine, the meteorite was first heated in the furnace, and then forged under the forging press, and the meteorite that had previously made Sheng Qingyun helpless was heated at a high temperature of 3,600 degrees and really became dough under the 100,000-ton forging press, and was squeezed out repeatedly, and a little impurity was squeezed out.

Until Sheng Qingyun opened the Qi Lookout Technique to explore the meteorite, and then repeatedly folded and forged, he couldn't squeeze out any impurities, the aura was integrated, without the slightest mixture, and a meteorite that was originally the size of a football shrunk in a circle, smaller than a volleyball, but the mass did not decrease much, and it still weighed ten tons, that is, 20,000 catties.

Flying back to the capital with the quenched materials again, and returning to the sword-casting room, Chen Yilong ordered the sword-casting furnace to be opened, and placed a batch of materials that Sheng Qingyun couldn't understand to assist in smelting meteorites in a specific position one by one.

Because the material that Sheng Qingyun used to forge the sword was too special, Chen Yilong made special improvements to many of the tools in the sword casting room, just to be able to cast this unprecedented sword weapon.

Special crucibles, robotic arms that can easily lift objects weighing up to 20 tons, special alloy hammers......

Chen Yilong can be said to have made the greatest efforts to forge this sword, and now at the last moment, Chen Yilong looked a little excited, and carefully checked every step of preparation, for fear that there would be any mistakes or omissions.

The sword-casting furnace was full of fire, exuding blazing heat, and the meteorites in the crucible were silent, Chen Yilong calmly instructed a few assistants to add all kinds of strange things to the furnace, and the temperature of the furnace was rising steadily......

The furnace was blazing, and after seven days and seven nights, the old man Chen Yilong, who had been staring at the sword casting room for seven days and seven nights, looked at the sword casting furnace and showed a smile, which had not been seen in the past seven days and seven nights, like a clear sky revealed by the fog.

Chen Yilong put the auxiliary melting materials that had been prepared earlier into the crucible, and the meteorite that had been smelted for seven days and seven nights finally changed color, and there were faint signs of melting, at this time, the old man Chen Yilong took a big bowl to Sheng Qingyun, and said: "Hurry up, let the blood!"

Sheng Qingyun was stunned, why did he still let himself bleed?

The old man was already impatient: "Hurry up, let the blood, this sword will be used by you in the future, use your blood to mix and smelt, so that the sword can be in harmony with your heart;

In a trance, the old man took a knife and cut his wrist, and put half a bowl of blood, Sheng Qingyun's blood is very different from the blood of ordinary people, not only bright red and bright, but also bright and bright, and there is a little starlight hidden in the blood, exuding a special fragrance, like a treasure medicine.

Chen Yilong was also surprised when he saw it, but he didn't care about the research at the moment, most of the bowl of blood was sent into the crucible, and the meteorite began to melt in an instant......

Sheng Qingyun turned around, realized the wrist wound, between a few breaths, the bleeding not only stopped, the wound had begun to heal, when Chen Yilong operated the mechanical arm to end the crucible, and carefully poured the molten meteorite liquid into the sword mold, the wound on Sheng Qingyun's wrist had completely healed, and only a red line remained, I believe that it will not be long before this red line will disappear.

Chen Yilong waited for the sword embryo infused in the sword mold to cool down, the temperature did not really drop, broke the mold, used the mechanical arm to manipulate the sword embryo and put it on the anvil pier, and swung the alloy sledgehammer on the sword embryo with one hand.

The old man danced the sledgehammer like rain to hit the plantain, fast and bright, repeatedly hammered on the sword embryo, hammered twelve times in a row, each time three hundred and sixty-five hammers, a total of four thousand three hundred and eighty hammers, the old man beat it in less than ten minutes, the powerful thing is that from beginning to end, the hammer sound is light and bright, without the slightest confusion, consistent.

After twelve hammers, Chen Yilong operated the mechanical arm to put the sword embryo into the furnace to continue heating, Sheng Qingyun curiously asked that there were air hammers in other workshops, why not use them here, but instead beat them with great effort.

The old man Chen Yilong glared: "You know a fart, the one with the electric hammer and the air hammer can really cast a divine weapon?" Although the electric hammer and the air hammer can achieve the accuracy of each hammer and the same strength of each hammer, it is always a dead thing, and what is created is just a dead thing. The real swordsmith casts the sword, and every hammer he swings will carry the swordsmith's own spirit, and every hammer will be combined with a trace of the swordsmith's spirit, and when the sword is cast, the spirit of the integration has the opportunity to make the sword weapon alive, spiritual, and become a real divine soldier......"
