"Brother Zhao has something to say, but it doesn't hurt to say it. Shi Mu's brows furrowed slightly.

"This knife is impeccable in terms of sharpness and toughness, but the junior brother should be more curious why this knife is so heavy, right? Such a heavy knife is unusable even for some martial artists who are born with divine power. Zhao Ping said slowly.

Shi Mu's eyes moved, and he didn't speak, but he did have this question in his heart.

Although the sword technique is not as light and elegant as the sword technique, it is also based on change, and a knife that is too heavy will naturally do more harm than good to ordinary martial artists.

There are people in the world who are born with divine power like him, and those who cultivate are still known for their strength, so naturally there will not be many.

"When Zhao got this piece of extraterrestrial meteorite, he was naturally ecstatic, and it took countless efforts to forge it into this knife. However, Senior Brother Shi may not believe it, when this weapon was just forged, the weight was actually only about 100 catties. Zhao Ping said with a wry smile.

"Only a hundred pounds?"

When Shi Mu heard this, he was shocked.

"I had no intention of selling the knife immediately after it was forged, but a few days later, something strange happened. The weight of this knife became heavier and heavier, and after a month, it doubled in weight, and in the second month, the weight increased again by about 100 catties. Zhao Ping sighed and said.

"There is such a strange thing?" Shi Mu said in disbelief.

It's hard to believe, but it's true. In the time that followed, the increase in the weight of the knife became slow, but now, it has reached 500 catties, and it should continue to get heavier in the future. Because the weapon is so heavy, no one has been able to use it, so it will always stay in the shop. Zhao Ping said with a wry smile.

"This is really weird, but the reason for this should be the material, it should be because of the extraterrestrial meteorite. Shi Mu said slowly.

This kind of knife increases in weight for no reason is unheard of, but looking at Zhao Ping's expression, it doesn't look like a lie.

Zhao thought the same, and asked some seniors in the door to see this knife, but no one recognized what kind of material it was. If Senior Brother Shi doesn't mind that this knife will be heavier and more staggering in the future, I'm happy to sell this weapon. Zhao Ping sighed and said.

"Well, this knife is so amazing, I want it even more. I don't know how much silver is needed?" Shi Mu said without thinking about it after a while.

With the cultivation of the Prajna Celestial Phenomena Skill, his strength will also increase, and he naturally won't care about the heavier of this knife. When Zhao Ping heard this, he showed a hint of hesitation, and only after a moment did he compare five fingers.

"Fifty thousand taels?" Shi Mu frowned slightly and said.

"It's 500,000 taels. Zhao Ping reported the number of Ran Shi Mu's face sank.

"Senior Brother Shi, it's not that Zhao Mou is asking for a sky-high price, when forging this knife, he spent countless precious materials, and some of them are even rare treasures that can only be used in refining magic weapons, and 500,000 taels is just enough for the next return. Zhao Ping saw Shi Mu change color, and hurriedly explained.

Shi Mu still frowned slightly.

The total amount of silver on his body now is about 400,000 taels, and I am afraid that he will have to paste some other things to make up for 500,000 taels, although this black knife satisfies him in all aspects, but it is unrealistic to spend all his wealth.

"In this way, if Senior Brother Shi doesn't have enough silver on him, then he can pay sixty percent first. For the rest, the junior brother will refine a batch of talismans for me, which can be regarded as offset, how about it?" Zhao Ping saw this, and after rolling his eyes, he suddenly proposed.

"That's fine, but I don't know if Senior Brother Zhao wants to refine those talismans?" Shi Mu's eyes lit up and nodded.

"Senior Brother Shi, wait a minute. Zhao Ping's face was overjoyed, and he hurriedly turned around and walked to the room, and after a while, he walked out with a blank piece of paper and handed it to Shi Mu.

"Well, that's it. ”

Shi Mu just glanced at the content on it, and agreed.

"Senior Brother Shi, don't worry, I will send someone to your residence later in the materials needed to make talismans. Seeing this, Zhao Ping was overjoyed.

Shi Mu nodded, took out 300,000 taels of silver tickets from his arms, and handed them to Zhao Ping.

"By the way, Senior Brother Zhao just said that the materials used to refine this knife are used to forge this knife, so I wonder if you can engrave some runes on this black knife and make it a real magic weapon?"

He didn't know much about magic weapons, but he had read it in the Spirit Rune Treasure Sutra, and the so-called magic weapons were to attach some runes to the weapon, so that it had some power that ordinary weapons did not have.

For example, by inscribed some fire runes on the weapon, the weapon can be made to emit a flame attack, which is much more powerful than ordinary weapons.

It's just that if you want to upgrade your weapon to a magic weapon, you have extremely high requirements for weapon materials, and only those weapons forged with the best materials are possible, and ordinary swords can't withstand mana infusion at all.

It is said that there is a spiritual weapon on top of the magic weapon, which is a treasure that really has spirituality, and it has gone beyond the category of weapons and belongs to the means of immortals.

It is said that there is a more powerful existence above the spiritual weapon, but what it is, Shi Mu doesn't know.

"Zhao has also thought about this matter, although I know some methods of refining magic weapons, but unfortunately, after this knife is cast and weighted, the blade of the knife becomes harder and harder, and ordinary flames cannot smelt it at all, let alone engrave runes on it. Zhao Ping shook his head and said with a wry smile.

When Shi Mu heard this, his face suddenly sank.

One of the reasons why he was willing to spend 500,000 taels of silver to buy this black knife was that he liked its special material, and it was likely to be refined into a magic weapon.

"However, this matter is not without a turnaround, I once heard from a senior in the Fire Separation Society that Uncle Ju of the Hidden Scripture Pavilion has a gold-turning lizard summoned from other interfaces, and the venom it spits can corrode almost all metal, softening it. Zhao Ping saw that Shi Mu's face was not good, and hurriedly said.

"Is this true?" Shi Mu was stunned.

Zhao had seen that senior ask for some venom from Uncle Ju to engrave runes on a very high-quality long sword, but the venom is extremely powerful, although this black knife is made of special material, but after all, it is also among the metals, so there should be no problem. Zhao Ping said affirmatively.

"Thank you Senior Brother Zhao for your advice, it seems that I am going to find Uncle Ju. After thinking for a moment, Shi Mu arched his hand to the other side, put the black long knife back into the wooden box, clamped it with one hand, and walked outside in a hurry.

Half an hour later, Shi Mu came to the second floor of the Scripture Pavilion.

"Hey, why are you this kid again, what are you doing this time?" As soon as he walked into the Scripture Pavilion, a sharp voice sounded.

In the huge golden birdcage, the parrot Cai'er flapped her wings, tilted her head to look at Shi Mu, and shouted loudly.

(Finally the third watch is over, and I'm almost tired of forgetting to speak!)
