Doing hard work is nothing to Su Xiaofan, he has been used to it since he was a child.

Her mother passed away early, her father was away from home all year round, and her grandfather was not in good health. Su Xiaofan used to take care of the two acres of land at home after school.

Later, he learned to make bronze ware, which was also a laborious job, involving making embryos and striking iron. When Su Xiaofan was in his teens, his hand strength was not as strong as usual.

Placing the Sky Thunder Stone on a large steel ingot in the middle of the room, Su Xiaofan raised the hammer and struck it hard on the Sky Thunder Stone.

The Thunder Gold Essence extracted from the Sky Thunder Stone is suitable for refining weapons. This does not mean that the Sky Thunder Stone itself is very strong. At best, it is just a stone with minerals.

With the help of Su Xiaofan's random cloak hammering skills, the nearly one ton thunder stone turned into rubble on the ground.

Su Xiaofan picked up some gravel and stuffed it into the smelting furnace. After almost a hundred kilograms of rubble was stuffed, Su Xiaofan stopped and turned around to think about the ground fire switch.

In fact, the operation of the underground fire outlet is quite simple. Several joysticks should be connected to underground valves to control the amount of underground fire.

Su Xiaofan didn't want to bother, so he came up and opened the valve that caused the biggest fire.

I saw a steel plate at the exit shrinking inward, and a ball of flames burst out from the ground.

The fires Su Xiaofan had seen before were all red, otherwise why would there be a word called fiery red?

But the ground fire that sprang out from the fire outlet was blue, and the color was a little purple. Although it was still three or four meters away from the fire outlet, Su Xiaofan could still feel the scorching heat.

Moreover, this fire gave Su Xiaofan an extremely dangerous feeling. Su Xiaofan immediately understood in his heart that this fire could definitely threaten his life.

The ground fire will automatically burn the smelting furnace above. The smelting furnace itself is made of an extremely heat-resistant material, and a lot of high-tech materials are added. Even at high temperatures of tens of thousands of degrees, the smelting furnace itself

Will not be melted.

Su Xiaofan only needs to wait aside. After reaching a certain temperature, the thunder stone in the smelting furnace will dissolve and decompose all the metal substances inside.

At this high temperature, those metals will also be turned into liquid, and then flow out from a hole like a spout of the smelting furnace. As for some impurities in the Tianlei Stone, they will be vaporized directly in the smelting furnace and be photographed.

Expelled.

This smelting furnace is a hundred times more advanced than the method of lighting firewood to melt the bronze when Su Xiaofan made bronze, so Su Xiaofan basically didn't have to worry about it.

Twenty minutes later, Su Xiaofan saw a fiery red liquid starting to flow out from the spout of the smelting furnace.

No matter what kind of steel it is, it will always be this color after melting. The liquid passes through a conveyor belt and flows directly into a groove on the workbench.

There was just a thin layer flowing under the groove, and the metallic liquid smelted from more than one hundred kilograms of Tianlei Stone had finished flowing.

Su Xiaofan was not busy looking at the metal that was gradually solidifying. Instead, he closed the fire outlet and then operated the smelting furnace to pour all the residue inside into the corner.

These are all automatically operated by a set of computer processes. Su Xiaofan only needs to press a few buttons. After he finishes refining the weapon, someone will naturally come in to clean it.

Su Xiaofan didn't know what kind of material this smelting furnace was made of. It cooled down quickly as soon as it left the ground fire.

After stuffing more than a hundred kilograms of Thunder Stone inside, Su Xiaofan repeated the operation just now.

Only more than a hundred kilograms can be smelted at a time. By the time the six to seven hundred kilograms of thunderstones are smelted, most of the day has passed.

From the groove of the workbench, I took out the result of most of the day's work. It was a piece of black metal weighing more than ten kilograms. If I looked closely, I saw that there seemed to be a faint golden luster in the metal.

"This should be Lei Jin."

Su Xiaofan looked at this piece of Thunder Gold dumbfounded. This was what the ancestor of the Sword Sect was talking about before, but his own system happened to purify the Thunder Gold Essence, so he had to come here to show off his acting skills.

Su Xiaofan thought for a moment, and simply took out the remaining piece of Thunder Gold Essence from his personal bag, and performed a complete act to make it feel real.

Throwing the piece of Thunder Gold Essence, which weighed only two to three hundred grams, into the smelting furnace, Su Xiaofan turned on the ground fire again.

This time it took more than an hour to burn, and even the smelting furnace was almost transparent, and a thin stream of metallic liquid flowed out.

Su Xiaofan let the golden water formed by the Thunder Gold Essence flow into the groove, placed the piece of Thunder Gold on the workbench, then lifted the Dragon Broken Stone and opened the stone door.

"Junior Brother Su, why did you come out so quickly?" Wen Wenming, who was sitting cross-legged and meditating outside, heard the noise and immediately opened his eyes.

"It's a bit boring, let's come out and take a breath."

Su Xiaofan smiled and shook his head, and said: "Junior brother, I still don't have enough concentration. I feel a little uncomfortable in that closed space. Come out and take a breath before continuing."

"You don't have cabin fever, do you?"

Wen Wenming looked at Su Xiaofan and said: "This cabin fever has nothing to do with advanced cultivation. Some people will feel anxious and fearful in a sealed environment. I have a nephew who has this disease."

"Senior Brother Wen, it's not as exaggerated as you said."

Su Xiaofan laughed bitterly when he heard this, "I was a little close to the fire just now. I was burned by the fire. I just feel a little stuffy. What does it have to do with cabin fever?"

"You're not hurt, are you?"

Hearing this, Wen Wenming quickly stood up and said, "I forgot to remind you, don't get too close to the ground fire. The ground fire above 7,000 degrees can turn us all into gas..."

"No injuries, just roasted."

Su Xiaofan shook his head and said: "Brother, do you have anything to eat? Since you are out, let's eat something before going in."

"With your current level of cultivation, do you still need to eat after three to five days?"

Wen Wenming said with some confusion: "You are about to reach the realm of Bigu, and you have the Bigu Pill I gave you. Why are you hungry so quickly?"

"Hey, senior brother, what does this have to do with whether you are hungry or not?"

Su Xiaofan opened his mouth and said: "Eating is for the enjoyment of delicious food and the enjoyment of the taste buds on the tip of the tongue. We can't become cultivators and just give up all the seven emotions and six desires, right?"

"Junior Brother Su, you, who has not released your true yang, want to talk to me about the seven emotions and six desires?"

Wen Wenming looked at Su Xiaofan with a half-smile, "Senior Brother, I have a grandson after all. Junior Brother Su, please find a Taoist companion first, hahaha..."

"I'm talking about appetite. Senior brother, how long has it been since you went out to eat in a restaurant?"

Su Xiaofan curled his lips and was looked down upon again, "Only when you taste delicious food in your mouth can you feel the beauty of life, otherwise what's the point of living for such a long time."

"What you said is true. Practitioners can't just practice hard. I'll go find a restaurant and have a good meal later."

Wen Wenming nodded, having lived to his age and seeing things more clearly than Su Xiaofan, he naturally knew the meaning of Su Xiaofan's words.

"How's your refining of the flying sword embryo going?"

Wen Wenming asked casually, but in refining the natal flying sword, others are not allowed to interfere, or even watch, so Wen Wenming just mentioned it.

"I'm still refining thunder gold. I took the refined thunder gold and refined it again to get some other metals."

Su Xiaofan said seemingly unintentionally: "That material seems better. I will refine the remaining thunder gold into that metal later and start refining the flying sword."

"Oh? The metal made from Lei Jin?"

Wen Wenming was stunned for a moment when he heard this. As far as he knew, Lei Jin was already the best material for refining the natal flying sword, but he didn't know the metal that was then purified.

"Okay, senior brother, I'm going in. Thank you for your hard work."

Su Xiaofan didn't give Wen Wenming a chance to see the metal, and walked into the weapon refining room while talking.

"This kid, are you still guarding me?"

Wen Wenming saw Su Xiaofan's actions and immediately burst into laughter. However, refining a flying sword is related to a sword cultivator's wealth and life.

Just like the formation engraved on the flying sword, whether it is offensive or auxiliary, whether it is fast or sharp, it is all very particular. The less others know about it, the less likely it is.

However, Wenming didn't know that Su Xiaofan's flying sword had no formation engraved on it at all.

The Void Flying Sword is born with three qualities. One is that it is fast. It is so fast that it can come and go without leaving a trace like electricity generated in the void.

Another feature is that it is sharp. It can be said that the defensive artifacts under the high-grade treasures can break through the void, so they can be said to be indestructible.

The last feature is naturally the power of thunder and lightning in the flying sword.

This power of thunder and lightning can not only strengthen Su Xiaofan's physical body, but also trigger the sound of wind and thunder to frighten the opponent when fighting against him.

Moreover, after the flying sword hits the opponent, even if it does not hit the vital point, the power of thunder and lightning can make its body stiff and slow in movement.

Usually if a formation can be successfully engraved on a flying sword, it can be regarded as a top-grade flying sword weapon.

If there is a master of weapon training who can carve two formations, the one that is not even close will be the best flying sword weapon. If you are lucky, you may be able to refine a treasure weapon.

Like the Void Flying Sword, it can be refined with three practical formation effects, and its power is even much greater than ordinary high-grade treasures.

That is to say, Void does not have a weapon spirit now, otherwise the level will never be lower than the spiritual weapon. Whether it can be strengthened into a spiritual weapon by following Su Xiaofan in the future depends on Void's fortune.

After closing the stone door of the refining room and putting down the Dragon Breaking Stone, Su Xiaofan started to get busy again.

Su Xiaofan was also helpless. Sometimes a lie requires countless lies to cover up.

But he really couldn't explain the matter of repairing the system clearly, and he couldn't talk about it. If he wasn't strong enough, he could only do it through acting.

Su Xiaofan put all the more than ten kilograms of thunder gold into the smelting furnace, then turned on the ground fire and adjusted the fire temperature to the highest level.

The almost purple flame gave Su Xiaofan an extremely dangerous feeling.

Under the burning of this flame, the smelting furnace turned red and almost transparent in less than half an hour. I don't know how high the temperature inside would be.

I don’t know what this smelting furnace was made of. Even in this case, it was not damaged, but no molten metal liquid flowed out.

Su Xiaofan was very patient, threw a Bigu Pill into his mouth, and simply started meditating.

The taste of Bigu Dan is a bit like fried soybeans. It is crunchy and crunchy in the mouth, but it melts in the mouth. After a while, a feeling of fullness is felt in the body.

Su Xiaofan didn't care, he just had a taste.

Immersing his mind in cultivation, the true energy in Su Xiaofan's body has been completely transformed into true essence.

The true energy flows in Su Xiaofan's limbs and bones. It seems gentle, but in fact it contains extremely powerful power.
