Shi Mu turned his wrist, and the magic pen fell on the meteorite black knife again.

"Senior Brother Shi, do you still want to superimpose it again......" Zhao Ping muttered in disbelief.

Shi Mu was silent, his movements in his hands were stable and smooth, and the drawing speed was increased several times at once, and after a while, the third rune array superposition was completed.

And then, without the slightest hesitation, he started the fourth time!

The temperature of the Meteorite Black Knife gradually decreased, and its color gradually changed from red to dark red.

Shi Mu's wrist slammed down, and he suddenly carved the last stroke, the hardness of the surface of the black knife has increased a lot, and it is much more difficult to portray......

On the casting platform, on the surface of the Meteorite Black Knife, which had almost recovered to black, a burst of red light flowed through the Flame Rune Array, and then slowly dissipated.

This is already the fifth rune array stack, and it has finally been successfully completed before the hardness of the black knife is restored!

But there's one more thing to do at the moment.

A red line was drawn from the flame rune array on the blade's body, extending all the way to the hilt.

Shi Mu took the golden lizard venom porcelain bottle and poured out a few drops of venom at the end of the red line.

After a burst of "snort" sounds, a shallow pit was corroded from the blade.

Shi Mu Mali took out a fire attribute spirit stone from his arms and inlaid it in the small pit, and then he turned his wrist and quickly outlined a few spirit patterns around the fire spirit stone.

Buzz!

The fire attribute spirit stone suddenly emitted a faint red light, as if blood flowed into the twelve runes of the Flame Rune Array on the sword body along the red line.

With a "boom", a layer of crimson fire appeared on the blade of the black knife, but then the flame of the blade dimmed, and the flame rune array returned to its original state.

Shi Mu's face was happy.

At this moment, the superimposed rune array was completely completed, and the Meteorite Black Knife also jumped into the ranks of magic weapons.

That fire attribute spirit stone is the source of spiritual power of the Flame Rune Array, and with Shi Mu's current mana, he can barely urge the five layers of superimposed Flame Rune Array, but if it is inlaid with spirit stones, it can naturally exert greater power.

The magic weapon can't exert much power in the hands of the acquired martial artist, because the true qi quality of the acquired martial artist is too poor, and it can't urge the rune array above to run at all, so it can only rely on the spirit stone inlaid on the magic weapon.

It's just that the spirit stone is extremely valuable, if it weren't for the special identity or strong financial resources, few acquired martial artists would use magic weapons against the enemy.

Only after the martial artist's cultivation has advanced to the innate realm, and the quality of true qi has been greatly improved, can he be transformed into mana through the formation and directly urge the rune array on the magic weapon to operate.

Zhao Ping was already stunned by Shi Mu's superposition of the five-layer rune array on the meteoric iron knife in one breath.

At this moment, his eyes were staring at the flame rune array on the black long knife, and after a while, he came back to his senses with a big breath, and said to Shi Mu in surprise:

"I have long heard that Senior Brother Shi is good at the Fu Array, and when I saw it today, I was really amazed!"

Senior Brother Zhao praised it falsely. Shi Mu turned around and said with a slight smile, the color of his pupils had already returned to normal.

"As far as Zhao knows, some of the full-time refiner apprentices in the sect are already extremely lucky to be able to successfully stack two rune arrays, and the number of magic weapons that have been stacked more than three times is very small, let alone a superimposed five-layer rune array like Senior Brother Shi. Zhao Ping's words couldn't help but have a hint of flattery, and he couldn't help but look at the black knife that had not yet cooled down.

Shi Mu smiled faintly, the ability of the mutation of his eyes made his success rate in such a thing as superimposing the rune array amazing, if it weren't for the limited time, it was estimated that he would have been sure of success if he stacked it a few more times.

When the power of the magic weapon is directly related to the rune array burned on it, the Flame Rune Array is only the lowest-level rune array, even if it is stacked five times, the power is far less than those magic weapons that have been engraved with a high-level rune array once.

Of course, the meteoric iron knife at this moment is far from being comparable to low-level magic weapons in the general sense. This is more than enough for the battle between the martial artists of the day after tomorrow.

A quarter of an hour later, the black knife of meteorite on the casting table cooled down completely.

Twelve dark red runes were clearly engraved on the body of the knife, as if it were natural, as if blood lines were flowing on the blade, making the black knife exude a faint evil aura.

A gleam flashed in Shi Mu's eyes, and he grabbed the hilt of the knife and placed it flat in front of him.

"It's really a rare high-quality magic weapon, the weight of the Meteorite Black Knife plus the instantaneous explosive power of the five-layer Flame Rune Array, the junior brother has this knife, and his strength has greatly improved!" Zhao Ping looked at the Meteorite Black Knife with some envy.

After being promoted to a magic weapon, the value of the black knife naturally increased greatly.

However, Zhao Ping is also a person with a downright personality, but he is a little envious, but he has no other ideas.

"Senior Brother Shi wants to test its power?" Zhao Ping said.

"Good!"

Shi Mu raised his eyebrows, moved greatly, and nodded.

This Meteorite Black Knife was the weapon he was most satisfied with so far, and he also wanted to try the power of the Flame Rune Array on it.

"Hehe, Senior Brother Shi comes with me, there is a training ground behind my shop, which is a place for guests to practice weapons. Zhao Ping smiled, walked out of the fire room with Shi Mu, and came to a wide open space outside.

There were many wooden figures wrapped in iron sheets in the clearing, and some boulders the size of grinding discs, with many scratches left by swords of various shades.

Shi Mu was a little excited in his heart, let out a long roar, and at the foot of his feet, the whole person instantly flew into the training ground, moving the knife like the wind, and performing the wind galloping knife technique with one move.

The meteorite black knife weighing five hundred catties was as light as nothing in his hand, moving with him, bringing a whirlwind.

Gradually, Shi Mu's knife technique became faster and faster, and the meteorite black knife turned into a black shadow hovering beside him.

Unconsciously, Shi Mu's heart became empty, and the wind gallop knife technique was used in a row, and the clouds and water were naturally incomparable, and later when he raised his feet and stretched out his hand, he had the shadow of the wind gallop knife technique.

A wave of heat gradually flooded into his heart, and it poured into his mind from all four limbs.

"Hah!"

Shi Mu suddenly shouted, the meteorite black knife slashed out, the shadow of the knife suddenly trembled, and instantly turned into thirteen black and misty sword lights, and the surging sharp sword suddenly spread, Zhao Ping, who was standing in the distance, was shocked in his heart, and couldn't help but take a step back.

Thirteen slashes in one breath!

Shi Mu was overjoyed in his heart, his galloping sword technique made great progress again, and finally reached the realm of Great Perfection, with thirteen slashes in one breath!

Before, he still relied on the effect of the light talisman to barely achieve it, but now he has finally completed the cultivation of this sword technique.

Sonorous!

The aftermath of thirteen sword rays slashed a huge bluestone like a rockery, and with a muffled sound, the boulder disintegrated violently, turning into more than a dozen pieces of gravel and scattering like straw.

"Whirring" is full of wind!

One of the stones the size of a millstone fell right on Shi Mu's head.

Shi Mu's eyes flashed, and the mana in his body was surging into the meteorite black knife.

The flame rune array above the black knife suddenly lit up, and a layer of crimson flame light emerged, enveloping the entire blade.

Shi Mu let out a low snort, and with a wave of his arm, the black knife turned into a red flame, slashing heavily at the boulder that fell down.

Boom!

The boulder the size of a millstone suddenly burst open, turning into a cloud of debris and scattering.

Shi Mu stepped a little, retreated a few steps back, avoided the scattered debris, and silently retracted his knife.

"Okay! Senior Brother Shi's sword technique is exquisite, and the power of the Flame Rune Array is really amazing, but in the end, Senior Brother didn't use all his power. Zhao Ping applauded and laughed, and walked up slowly.

Shi Mu nodded, just practicing the sword technique, he naturally wouldn't do it with all his might, he just triggered a layer of rune arrays.

"Yes, it's a good knife!"

At this moment, a slightly hoarse voice came from outside the drill field.
