Lu Shaoyu was in a very happy mood, he bought a broken knife casually and came back, and he actually got a piece of Xingchen Essence Iron, this luck was simply against the sky.

Carefully put the Xingchen Essence Iron into his arms and hid it, his mind did not continue to focus on this piece of Xingchen Essence Iron, but wholeheartedly controlled the molten iron ball, preparing to refine some Iron Essence and refine a small flying sword for himself.

The melting temperature required for Xingchen Refined Iron is too high, and the temperature of Yang Huo is simply not enough, so it has to be put aside for the time being, and there will be a chance to refine it later.

※※※※※※

Just when Lu Shaoyu was overjoyed to get the Star Essence Iron, under the mountain range a mile away in the distance, an old man looked up at the sky with his white head up, looking strange and surprised, and said to himself: "This ...... What's going on?"

This old man was a little thin, wearing a gray-white robe, with two sun patterns on his left chest, and he was the intermediate elder of the Xuanyang Sect. If Lu Shaoyu was here, he should know that he was Guo De, the old guy who went to Lujiazhuang with Sun Li back then.

At this time, Guo De's eyes showed a confused look, his eyes were half-squinted, and he raised his head to look up at the sky.

The sky was clear, and there was not a single floating cloud, but when he just stepped into here, he suddenly felt a trace of coldness, and the sun's rays on his body were not as hot as just now.

He is a martial artist of the innate realm, and his senses are extremely keen, and he is also a formation master, and he knows how to use the surrounding environment to arrange formations, so he must pay more attention to the subtle changes in the surrounding environment than ordinary people.

As he stepped inside, he felt the temperature of the sun suddenly become much colder. Just looking up at the sky, the sun's rays are exactly the same, not the slightest abnormal.

It feels weird!

"Is it a delusion?"

Guo De muttered to himself, he felt as if there was an invisible barrier in the sky, blocking the part of the sun that was blazing.

Rubbing his white head, he suddenly stepped back.

As soon as he took a few steps back, the sunlight shining on his body became hot again.

"Not a delusion......"

Guo De was shocked, and in order to verify that he did not feel wrong, he took a few more steps forward.

The sunlight shining on his body really cooled down again.

"This sunshine is separated by two places not far apart, but the temperature is actually different?" Guo De looked confused, raised his head, and muttered to himself.

In order to verify his guess, he walked back and forth several times. It turned out that just one step away, the temperature of the sunlight shining from the same sky was completely different!

He looked up at the sky, his eyes puzzled.

If something goes wrong, there must be a demon!

This place, there are quirks!

Guo De was originally going to go to other places to do a trivial errand, but when he passed by here, he found that there was something strange here, and immediately left an unimportant thing behind him and wanted to find out.

He relied on his body's senses to walk along the line between hot and cold sunlight, marking as he went. Half an hour later, he found that the route he had taken was a big arc.

It seems that after entering the range of a circle, the temperature of the sunlight suddenly drops.

If it is a circle, then, the thing that causes this reason, the ** of ten is in the center of this circle......

Guo De quickly analyzed in his heart, he looked at the mark he made, calculated the arc, and then, his eyes looked into the distance, and mountains quickly swept in his eyes.

Eventually, his gaze was fixed on a low, inconspicuous hill.

"It's there!"

Guo De was sure in his heart, and as soon as he stepped on his feet, his body turned into a flowing shadow, and he quickly walked towards the mountain.

The mountain was not far away, and in the blink of an eye, he came to the bottom of it.

Guo De stopped and looked up at the mountain. I saw that there were only a few stones and some weeds and trees on the top of the mountain, and there was nothing else, it was very desolate, and it should be inaccessible in normal times.

He hesitated, but finally walked towards the summit.

※※※※※※※※

Lu Shaoyu was refining a flying sword in the secret place at the top of the mountain. The mass of crimson molten iron that turned into a liquid was pulled by Lu Shaoyu's gravitational technique, constantly changing shape, and slowly calcining on top of the yang fire.

Every time he calcined for a while, Lu Shaoyu would open his mouth and spray, spewing out a mysterious force with sharp gold qi surrounding the molten iron. The crimson molten iron made a sizzling sound under the wrapping of this sharp gold power, and some impurities were constantly separated.

Although this broken knife is made of refined steel, sharpening iron like clay, it is indeed a rare treasure knife for ordinary people.

However, for a powerful monk, as long as his cultivation is high, even a wooden sword and a wooden sword can sharpen iron like clay.

Therefore, the worldly sword and sword are just a commodity for them. Lu Shaoyu naturally wouldn't go to such great lengths just to refine an ordinary sword.

All he wanted was the iron essence that came out of the hundred refined steel knives.

Iron essence is the essence of metal iron, and ordinary iron ore can only be refined into one or two taels for tens of thousands of catties. This broken knife is made of 100 refined steel, after countless tempering, the content of iron essence in it is naturally much higher than that of iron ore, and now it is estimated that it can refine five or six taels of iron essence from this broken knife.

It shouldn't be a problem to make a finger-sized flying sword with these iron essences!

When the cultivation reached the fetal period, Lu Shaoyu's gravitational technique had increased a lot, and it was not a problem to control the flight of a small flying sword. This flying sword is hidden on the body, and it can be killed by surprise, which can have an unexpected sneak attack effect.

This is a weapon to protect one's life!

The impurities were constantly separated, and with the help of the Sharp Gold Mysterious Power, the efficiency of the smelting was greatly improved, and in the blink of an eye, those useless things were separated, leaving only a molten iron the size of a baby's fist.

In the crimson molten iron, sharp white rays occasionally flashed, these were the iron essences that Lu Shaoyu needed.

"Condensation!"

Lu Shaoyu drank lightly, his palms changed rapidly, and more than a dozen magic seals were slapped one after another on this ball of molten iron. Immediately, he opened his mouth and sprayed three mouthfuls of sharp gold Xuanli into this molten iron.

With the entry of the Sharp Golden Mysterious Force and the magic circle, this molten iron changed, and under the traction of gravity, it slowly turned into the shape of a small sword.

Molten iron melted into a liquid state, the shape can be changed at will!

Lu Shaoyu took out an empty hand, took it into his arms, grabbed a small handful of refining stone powder, and withdrew it from the molten iron bead.

The refining stone can fuse the divine sense, and the powder of the refining stone is added to the small sword, and when the divine mind can be released in the future, it will be more convenient to control.

Lu Shaoyu carefully controlled the direction of the gravitational technique and controlled the changes in the molten iron. After a while, a finger-sized sword blank appeared on the yang fire.

The sword blank has been completed, Lu Shaoyu controlled the gravitational technique, and modified the shape of the little sword to look better. Immediately, with both hands, he pulled the small sword out of the calcination of the yang fire and suspended it in mid-air, waiting to cool down.

"Poof!poof!poof......"

While cooling, his mouth was not idle, and wisps of sharp gold power spit out from his mouth and wrapped around the sword.

The sharp gold power poured into the sword body, which could increase the sharpness of the small sword.

Lu Shaoyu is using the temperature of Ruijin to raise the flying sword. Suddenly, his brows furrowed slightly, he turned his head, looked under the mountains, and said in surprise, "Hey, someone is coming......?" (If you think it's good-looking, don't forget to collect and recommend support! Thank you!!) =^_^=
