> Wang Laoba came over and took the Seven-Star Ancient Sword from Ye Qing's hand, and the light groan of the Seven-Star Ancient Sword suddenly stopped.

As the soft groan of the Seven Star Ancient Sword stopped, the Cold Moon Sword gradually returned to normal, no longer so cold. The two weapons, as if they had lost their previous movements, turned back into ordinary weapons.

Ye Qing was surprised and said curiously: "What's going on?"

Wang Laoba asked rhetorically, "Do you know what a famous weapon is?"

Ye Qing shook his head, he didn't know these things at all.

"The so-called famous weapons are the weapons forged by the predecessors. In ancient times, casting weapons was a very cumbersome thing, unlike in modern times, where it was enough to directly suppress it with a machine. In ancient times, there were special foundry masters for casting weapons. And these foundries have their own superb casting methods, and they can cast all kinds of sharp weapons!" Wang Laoba paused for a moment and said, "However, those weapons are all forged from ordinary materials. A really good weapon is still to choose special materials to forge. For example, this cold moon knife is forged with cold iron that has been suppressed under the glacier for thousands of years. ”

"What is Cold Iron?" Ye Qingqi said.

Wang Laoba said: "You let me be specific, I don't understand, anyway, according to research, this is an iron with complex elements, and it may be the material left behind when the space meteorite hit the earth." ”

"Oh. Ye Qing nodded and said, "Speaking of which, it's not called cold iron, it should belong to the material that the earth doesn't have." In outer space, there are indeed many rare elements that the earth does not have, could it be these things?"

"So to speak...... Wang Laoba glared at Ye Qing and said, "Damn, do you want to know the special features of these famous weapons, or discuss chemical knowledge with me?"

Ye Qing hurriedly waved his hand and said, "You continue, you continue." ”

Wang Laoba glanced at Ye Qing unhappily and said, "Cold iron is a thing that has extremely strong coldness. Coupled with the fact that the previous year was suppressed under the glacier, the cold was even stronger. This kind of thing, you want to melt it down and cast it into a weapon, it's basically impossible. ”

"Why?" Ye Qingqi said.

"Why do you have to ask this?" Wang Laoba said: "Do you think, the cold iron is such a cold thing, it is the fire that is frozen out when it encounters it, how can it melt it?"

"I see!" Ye Qing suddenly realized, looked at the Cold Moon Knife in Wang Laoba's hand, and said curiously: "Then how is this weapon made?"

"That's the point I'm going to talk about!" Wang Laoba said: "In ancient times, the casting of weapons had their own extraordinary means. Just like this kind of cold iron, ordinary craftsmen have no way to take it, but top craftsmen still have their own unique methods. According to legend, this Cold Moon Knife was created by a great foundry named Zong Yue. He put this piece of cold iron in an active volcanic crater, and used the power of volcanic magma to bake it for three years before he could suppress the cold nature of the cold iron. Then, he immediately placed the piece of cold iron in the ice storage he had prepared earlier. Then, a miraculous thing happened, the cold iron that had nothing to break was actually broken and shattered, turning into small pieces one by one, you say this is not magical!"

Ye Qing thought for a while and said, "This can only be regarded as an ordinary thermal expansion and contraction, not magical." Even if you take a piece of regular iron, bake it long enough, and then freeze it, it will break. ”

"Really?" Wang Laoba scratched his head and said, "What is hot expansion and cold contraction?"

Ye Qing was stunned and said, "You...... Didn't you go to school?"

"Who said that my primary school diploma is still at home!" Wang Laoba replied angrily.

Ye Qinghu looked at Wang Laoba suspiciously, and said, "Shouldn't you buy this graduation certificate like Brother Li's?"

Wang Laoba was a little embarrassed, didn't look at Ye Qing, and said, "You just say, what is hot expansion and cold contraction, why are you talking so much!"

Ye Qing said: "Thermal expansion and cold contraction is a physical phenomenon. When something is heated, it will grow in size and expand. If it is cold, the volume will shrink, which is called thermal expansion and cold contraction!"

"Really?" Wang Laoba suddenly came to his senses and said, "This ...... Is this kind of physical phenomenon applicable to humans?"

"It's all applicable!" Ye Qing looked at Wang Laoba's suddenly glowing eyes, frowned slightly, and said, "But, Eighth Master, don't blame me for not reminding you." If you don't get enough heat, it won't get much bigger. And the human body is all muscle tissue, and when heated severely, it will damage the human body, so don't have any bad ideas!"

"Damn, didn't you say it earlier!" Wang Laoba said angrily: "Ya, I'm still thinking, this hot expansion and cold contraction, can it be used as viagra in the future......"

Ye Qing was speechless for a moment, this old guy, the thoughts in his head were as dirty as his appearance.

"Forget it, let's continue to tell you about the Cold Moon Knife. Wang Lao Ba said: "After Master Zongyue made the cold iron into a small piece, he smelted it separately, and the coldness of this cold iron decreased a lot, and it was slowly melted. Then, Master Zongyue tempered all these melted cold irons together to create a peerless divine weapon, which is this Cold Moon Knife!"

"Although this matter is simple to say, in fact, the price that Master Zongyue paid in order to forge the Cold Moon Sword was very large!" Wang Lao Ba said: "When the Cold Moon Knife came out, I don't know what the reason was, those melted cold iron actually showed signs of dispersing, and they couldn't be fused together at all. Seeing this, Master Zongyue immediately bit his finger and dripped blood on the knife. Strange to say, where the blood dripped on, the cold iron slowly fused. However, where there was no dripping of blood, the cold iron continued to disperse. In the end, Master Zongyue had no choice but to cut off his left arm and sprinkle blood all over the knife body, so that this Cold Moon Knife could be completely formed. However, Master Zongyue's arm is completely scrapped!"

Wang Laoba sighed and said, "Actually, not only is this the case when the Cold Moon Knife is baked, but even many other famous weapons are like this when they are baked. The legendary cadre Mo Evil Sword, when it came out, used the lives of two swordsmiths to pay tribute to the formation. Therefore, since ancient times, famous artifacts are very rare, first, materials are scarce, second, there are not many skilled casters, and third, there are not many casters who are willing to sacrifice!"

Ye Qing looked at the sword next to him, what Wang Laoba said was very magical, but he had a different opinion. He went to college, and he was always skeptical of superstitious things. In his opinion, Master Zongyue had to sprinkle the Cold Moon Knife with blood in order to make the cold iron condense, which was actually chemical knowledge. Just like modern steelmaking, some other elements must be mixed in it to control the hardness and strength of the steel. At that time, Master Zongyue sprinkled the Cold Moon Knife with blood, and it was probably the same reason!

"You've been talking about it for so long, and you haven't explained it yet, why is this sword like this?" Ye Qing said.

"Don't worry, let me tell you slowly. Wang Laoba said: "Since ancient times, famous weapons are very rare, but once a famous weapon is released, it will inevitably become the object of competition for heroes in the world." Why? Because all the famous objects are spiritual, and they can confess the Lord. Once it is recognized by the famous weapon, then the famous weapon will exert extraordinary strength in the hands of this person. Just like your current situation, if you instill your internal strength into the Seven-Star Ancient Sword, your internal strength can be multiplied, and the power is very amazing. ”

"When the Seven-Star Ancient Sword recognizes you, it will regard you as its master. And just now, you took the Seven-Star Ancient Sword and pulled out the Cold Moon Sword, and the problem came. Wang Lao Ba said: "The Seven-Star Ancient Sword and the Cold Moon Sword are both famous weapons with spirituality, and both are very powerful. Before the name is recognized, it is actually hostile to anyone. Just like Cui Yulong's ink-patterned black gold knife, that knife is very evil, and before he recognized Cui Yulong, he would be injured when he touched the handle of the knife. Although the Cold Moon Knife is not as evil as the Ink Pattern Black Gold Knife, it is also hostile to you. ”

"And you were holding the Seven-Star Ancient Sword at that time, and the Seven-Star Ancient Sword recognized you as the master and would do its best to protect you. At this time, if there is another famous weapon that is hostile to you, the Seven Star Ancient Sword will naturally protect you with all its might. Therefore, the Seven Star Ancient Sword let out a light groan, which was actually deterring the Cold Moon Sword. And the Cold Moon Sword felt the power of the Seven-Star Ancient Sword, and slowly began to release cold energy, which was competing with the Seven-Star Ancient Sword. However, once you let go of one of your weapons, the hostilities will end without any further movement!"

Ye Qing was dumbfounded when he heard this, these things sounded simply magical. Two weapons, but there is still a sense of hostility and friendliness? Moreover, they will fight against each other, are these two weapons, or two people?

"Eighth Master, what you said is a bit exaggerated...... Ye Qing said in a low voice: "Isn't it just two weapons, and you can still have independent consciousness, so you can't be refined?"

"Hehe......" Wang Laoba looked at Ye Qing and said, "Two weapons? Xiao Yezi, you know, from the day they were born to the present, how many people have died under their cold light, and how many people have died in order to fight for them." These are human lives, living human lives. With so many people dead, it's not an exaggeration to say something strange happens!"

Ye Qing looked at these two weapons in amazement, he still didn't quite believe Wang Laoba's words in his heart. You must know that in his opinion, these statements are all deceptions of charlatans, and they are all feudal superstitions. However, since the last time in Xishan City, Wang Laoba predicted Liu Changping's matter, Ye Qing had to believe that Wang Laoba still said some things very accurately. It's just that these superstitious things, do they really exist?

"Ye boy, it is already very difficult for you to get the Seven Star Ancient Sword to recognize you. After you have the Seven-Star Ancient Sword, you don't have to think about the Cold Moon Sword anymore, and it is impossible for the two famous weapons to agree with one owner. Wang Laoba weighed the Cold Moon Knife and said, "I advise you, it's better to find someone and sell this Cold Moon Knife." Keeping this weapon in your hands will always be a bane!"
