After being stunned for a while, Luo Yu rolled up his sleeves, picked up the black hammer, and gently knocked on a piece of copper essence with a thick arm, and the foot of the copper essence was still numb, he was afraid that the copper essence would shatter the hammer, and he would be much more cautious this time.

Bite!

There was a crisp sound, very pleasant, and it lasted for a while before stopping, and I looked at the hammer and the copper crystal to see that there were no traces left on it.

Ding! Ding!

Harder than once, hammered three times in a row, the crisp sound was endless, and then saw that the edges and corners of the copper essence had been hammered flat, and there was no trace left on the black hammer.

"Found a treasure!" Luo Yu looked at the traces on the copper essence and the hammer, and exclaimed, at this moment, he saw that the dark hammer was so cute, and his face was full of smiles.

"It seems that this copper essence hammer is continuous, and it can only be dug up!" Luo Yu had already used his greatest strength, thinking that he could smash the copper essence, but who knew that it was just smashed and deformed, so he could only excavate.

Helpless did not take advantage of the tools, he began to plow the ground with the handle of the hammer, a little bit of planing, the more he dug the more frightened, this looks at the surface of the fist-sized copper essence seems to be just the tip of the iceberg, the following staggered roots are complex, digging out a small pit three feet deep, three feet wide, from the inside to pick up the copper essence, it took a lot of effort, the copper essence is full of thirty or forty catties, this toss took two hours.

Fortunately, when digging copper essence, I dug out pieces of coke at the same time, and I filled a bag with twenty or thirty catties!

"Making money is really hard work!" After drinking water and wiping the sweat from his forehead, Luo Yu sighed.

Holding the copper essence and carrying the coke, the whole body carries seventy or eighty pounds, which is certainly nothing for people who often do coolies, but for a person like him with fine skin and tender meat, it is very difficult, and he walks for a while, and the shorter he walks, the longer the rest time.

Originally, it was only two miles away, and it took a maximum of twenty minutes to walk, but Luo Yu walked for more than an hour to arrive, and he had forgotten how many times he had rested during this period.

Seeing that the hour was not early, he hurriedly prepared to make a fire to cast a sword, and he was really going to start a fire, but suddenly it was difficult, and the Taixuan Sutra Gods and Demons was just a simple introduction to the sword furnace, as well as the materials needed for sword refining. As for how to refine the sword, there is no mention of it.

"It's really like a mountain!" Sitting on the ground looking at the sword furnace, copper essence and a pile of coke, Luo Yu looked up to the sky and cried out sadly.

Suddenly, a flash of inspiration flashed in his mind, remembering the picture in the movie, after lighting a fire, he threw the refining materials into the sword furnace, and then scooped up the hot molten slurry and poured it into the sword mold, seeing that there was a mouth under the sword furnace that seemed to flow directly into it by himself, he had an idea in his heart.

He hurriedly threw some coke into it, the flames quickly disappeared, and then the coke was slowly ignited, and the coke was red and green flames appeared, and when the coke was ignited, he quickly poured all the coke into it, and suddenly sparks were shining, and the smoke was burning.

"Faint! Ahem! This is really not a good job, I fought for my life!" The coke smoke was very choking, he was choked and had difficulty breathing, and the smoke and dust were so smoky that tears flowed out of his eyes, but he knew that there were too many dangers at night, and no matter how difficult it was, he had to persevere.

Soon the coke was completely burned, and the entire sword furnace was burned red, seeing that the time was almost up, Luo Yu took a step back and was about to throw the copper essence in, and he was just about to bow his head at the moment, when he found a surprising scene of flowers, birds, fish and insects carved on the sword furnace, which seemed to be alive and floated gently.

"What the hell is this!" Luo Yu was very surprised, looking at the carving on the sword furnace in a daze, and couldn't help but touch it with his hands, but he was even more shocked that the sword furnace had been burned for a long time and was still cold to the touch. If it is made of any material, it will also conduct heat at high temperatures, looking at the sword furnace and then looking at the black hammer that he has been carrying today, he firmly believes that this is a strange treasure, beyond his cognition, it seems that it does not belong to this world. Not to mention him, anyone in the outside world would be shocked.

Afraid of missing the opportunity, there is no time to continue to study this magical furnace, he quickly picked up the copper essence and threw it in, the moment he threw it in, he suddenly remembered that the temperature required to melt the copper was very high, and this furnace coke fire needed to cooperate with the blast device to increase the temperature to melt the copper essence, but he didn't have these things at all, and the sword furnace did not design this outlet, thinking of this, he was anxious, only the coke was burned but it was gone, and it was too late to see the sky.

Just when he was anxious like an ant in a hot pot, the moment he stretched out his head to look into the furnace, he found that the copper essence began to melt slowly, the coke had all been dyed red, the red flames suddenly rushed up, and a storm was formed in the sword furnace, and there was a coaxing sound, and the rolling heat wave hit his face was illuminated red, and a trace of hair fell in the air and instantly turned into ashes.

"This is simply Laojun Furnace!" Luo Yu exclaimed.

After about a cup of tea, a large piece of copper essence turned into molten slurry in the scorching furnace fire, slowly sinking downward, and then the red and bright copper slurry made a snorting sound and slowly flowed along the trench towards the sword mold, the bright molten slurry illuminated the entire circular black stone wall, and the molten slurry gradually filled the entire sword mold, and the molten slurry in the stone trough seemed to have a spiritual general reverse flow back and flowed into the furnace.

Looking at the molten slurry in the sword mold again, there was a bright red color that kept making a snorting sound, and the strange thing was that after half an hour, the molten slurry was still as bright as ever, and the hot gas rose without the slightest sign of cooling, completely subverting common sense, but so many strange things, he was used to it.

After thinking for a while, a flash of inspiration flashed in his mind, and his eyes fell on the ancient well by the sword stove next to the vegetable garden, and the clouds under the feet of the lifelike dragon on the ancient well seemed to be half fluttering, and he thought of using well water to cool down, but he didn't know if it worked.

Walk to the ancient well, look into the well, the well water is only half a foot away from the well surface, and the water is bubbling and tumbling, it seems that there is a spring under the well to continuously produce water, but the well water does not rise a bit.

Luo Yu had no tools, so he could only hold the water in his hands, and the well water was so warm that it was like a hot spring, and he quickly splashed the water on the molten slurry in the sword mold.

Phew!

The mist rose up, the red light flickered, and the originally bright molten slurry in the sword mold actually began to darken, and after a while, it turned red, Luo Yu sprinkled water several times, and he didn't walk in front of the sword mold until there was no fog at all.

I saw that this red sword was integrated, smooth as a mirror, and there was a faint cold light, and there were feathers and cloud-shaped patterns on it, and the sword model was only three fingers wide, three feet long, with a sword handle of seven inches and a sword grid of three inches, so it was a relatively delicate sword.

Stretched out his hand and grabbed the hilt of the sword in the sword mold, his hand was cold, and he picked up the crimson sword, and suddenly the cold light was shining, and the weight of the sword was just enough to hold the sword in one hand, and then look at the blade Although it had not been forged in any way, it was extremely sharp, without even a trace of burrs.

With one hand, he held the sword in his hand and picked up the sword, which was all the bluffing tricks that Luo Yu learned before, but at this time, he danced with the sound of breaking the wind.

It's called ...... Affectation!

Suddenly, Luo Yu changed his sword to a flat one, and smeared it on the fence, like a broken bamboo.

Swish!

The bamboo tube on the fence was cut off in an instant, and the fracture was flush, smooth as a mirror, without a trace of mud and water.

Good sword!
