Ou Yexia smiled coquettishly, "Sir, I was joking."

"Why don't you have a fight with me?" Yang Gan shook the dragon-slaying knife on his shoulder and said with an unruly expression.

"Sir, are you joking?"

Yang Qian's originally dark face immediately showed a smile, "I'm joking too."

...........

Ou Yexia suddenly breathed a sigh of relief. Fighting Yang Gan? It would be easier to commit suicide.

"Put some sweets on Krisna's armor. She has grown taller recently, otherwise I'm afraid she will come to find you someday."

Thinking of Krisna's majestic body and violent personality, Ou Yexia couldn't help but shudder and nodded in agreement.

Yang Qian smiled and headed back into Zhuangzi while carrying the dragon-slaying knife.

As long as you don't hold it with one hand, you can still bear it. Although it will be tiring to hold it with both hands, there is no problem if you hold it on your shoulders.

It was almost time. Yang Qian returned to the third floor, and the stairs made a "rattling" sound.

Sitting on the mat, Yang Gan couldn't help but hold the dragon-slaying knife in his arms. This was a magic weapon, and he wouldn't exchange it even for a Lamborghini.

The more I looked at it, the more I liked it, and I couldn't help but kiss it.

At this time, the sound of footsteps suddenly stopped. Zhang Yumeng stood at the top of the stairs, looking at Yang Gan and raising his eyebrows.

"What, do you have a fetish?"

"You know what the heck, this is a good thing. Ou Yexia made it from the meteorite he dug up last time."

Zhang Yumeng immediately ran over curiously and wanted to pick up the knife, but found that it could not be shaken at all.

"Don't hold on, I want to take a look."

"I didn't catch it. This knife weighs two stones, and the scabbard is not light either. I was afraid I would smash you."

Zhang Yumeng suddenly became interested: "What, this is a knife made of meteorites, it's impossible."

Yang Qian immediately hugged the knife and kept raising his face, "Nonsense, there is nothing impossible. Isn't that how it is done in martial arts dramas?"

"That's for acting. Aren't you very familiar with ancient cold weapons? How many meteorites have fallen since ancient times, and how many cold weapons were forged from meteorites?" Zhang Yumeng asked, touching the scabbard.

Yang Gan frowned and thought for a while, "According to information on the Internet, the earliest recorded weapons made of meteorite iron should be from the Shang Dynasty in the history of our country, about three thousand years ago."

"There is also a knife called Fire Meteor, which was made by a farmer in Europe in the 17th century out of meteorites. What is very strange is that this knife can maintain a constant temperature of 20°C no matter how low the temperature is. And when you use this knife The wound cut by the knife will bleed."

Zhang Yumeng spread his hands and said, "This is not the case. Since ancient times, the proportion of weapons forged from meteorites has been pitiful compared to the weapons forged locally. The main reason is that the density of meteorites is uneven. It is not a good material for forging cold weapons at all. Most of them are Iron-nickel alloy is not very useful."

"Ouch~~~!"

Yang Gan directly pulled out the knife. The dark blade had no reflection at all, but it was filled with a violent aesthetic.

When Zhang Yumeng saw the two words on the handle of the knife, he couldn't help but twitch the corner of his mouth, "Slay the dragon?"

"You're a brother, come and chop me down?"

"999 for one knife."

Yang Gan was surprised and said, "How do you know? You also play Legend?"

"What a joke, this ad pops up on my computer every day. It's hard not to see it. I didn't know what I clicked wrong once. I was hacked by Zha Zhahui all afternoon. I can even memorize the lines." Zhang Yumeng He spread his hands and showed a helpless expression.

Yang Gan pondered for a while, raised his brows, and showed an expression that everyone understood: "Do you often click on unclean websites?"

"Fuck, how did you know?" Just after finishing speaking, Zhang Yumeng suddenly covered her mouth.

"Nonsense, that kind of website is very unclean. Although there are no viruses now, there are too many junk ads."

"Wait a minute, why are you so skilled?" Zhang Yumeng asked suspiciously.

Yang Gan shook his head and sighed, "I was hacked by Zha Zhahui for several days."

"By the way, have you got that phone?"

Zhang Yumeng waved his hand and immediately lay down on the cushion, "Oh, forget it, the phone? That's a matter of course. You have to make a battery first, otherwise how will it start without electricity."

"Then you should do it."

Zhang Yumeng spread his hands, how could it be so simple? "Brother, I don't have any equipment. I'm thinking of a way. By the way, I'm going to go find Shui Hu and Shi Huacai tomorrow."

Yang Gan asked curiously, "Why are you looking for the two of them? It's not easy to find them now. They are out exploring minerals and waters all day long."

"Get some green vitriol or bile vitriol, and use a still to calcine it to produce sulfuric acid. But I'm afraid it won't be pure, so I have to purify it and get some distilled water. 80% sulfuric acid and 20% distilled water will be the electrolyte."

"But before that, we need to get a gas mask."

Yang Gan looked her up and down and said, "Why? What do you want to do?"

"Please, the smoke from that thing is poisonous. You don't want me to die early."

"Okay, okay."

Zhang Yumeng stretched out his hand and twisted it, with a look on his face that said you understand.

Yang Qian immediately moved back and said with a vigilant look, "You won't spend it all so quickly on one thousand gold. This can equip an army of three to four hundred people."

"I want the military talisman."

...

"You don't want to kill me, do you? Hey, it won't do you any good if you kill me." Yang Gan said with a bitter look on his face.

"Why do you always think so bad of me? I'm not planning to find a few people to boss you around and hand over some dangerous things to them."

Yang Qian nodded, it was okay to say, "Yes, but I can't give you the military talisman."

He immediately wrote a warrant, stamped it, and handed it to her.

"This warrant can mobilize fifty soldiers. When it's dangerous, you'd better capture a few Huns slaves to do it. The soldiers are all our own."

"According to what you said, it must be poisonous. It's better not to harm my soldiers. I brought these people out myself. If any one of them is injured, I feel bad."

Yang Qian was a little worried and warned him repeatedly.

"good."

After Zhang Yumeng finished speaking, he lay down on the ground with a big character.

"I'm so exhausted, let me touch your knife~~~!"

"Which one can you tell me?"

"Sister, I don't want to play with toothpicks now."

"Damn it, if you talk like this, you won't have any friends in the future." Yang Gan looked angry.

Although hormones are hibernating now and people are growing crookedly, at heart they are still pure men, okay? They are really one of their own, otherwise they would have been split into two and then chopped into three by Yang Qian's dragon-slaying knife.

Despite the scolding, he handed the knife to Zhang Yumeng cautiously, fearing that he would accidentally smash Zhang Yumeng. It weighed more than two hundred pounds and it was normal for his hands and feet to be severed.

Zhang Yumeng sat up and kept touching the back of the knife, frowning and muttering, "Weird thing...

..”

"This meteorite is very strange."

"How is the hardness and toughness?"

Yang Gan thought for a moment and said, "I don't know about the toughness, but the hardness is perfect. I heard old man Ou Ye say that it was very simple when it first started to be smelted, but it became very difficult to destroy after it was formed."

Zhang Yumeng was surprised and said, "Impossible? There is no such thing in the periodic table of elements. What you are talking about is like Edman alloy."

"Hey, you are thinking the same thing as me. You said it is a meteorite. It must be something from outer space. The periodic table of elements is just based on the elements of the earth."

Zhang Yumeng looked at the sword, smelled it carefully, and shook his head, "There used to be a smell of rust, but now it's gone. I've never heard of this kind of metal, but it's not like pure metal, but like a natural alloy."

After sheathing the knife, Yang Gan said proudly, "I don't care what kind of metal it is, as long as it cuts people quickly, this one will be my exclusive weapon from now on."

"Haha, do you have the Dragon Slaying Sword, or the Heavenly Sword?" Zhang Yumeng sometimes thinks Yang Qian is quite interesting, no wonder men have never been able to grow up.

He must have been around thirty years old before he traveled through time, yet he was as playful as a child.

"I have asked Fei Lian to dig up all the meteorites near Tang State. Such good things should be in my own hands. If it is really allowed, it will not be impossible to forge a Heavenly Sword. ."

Zhang Yumeng rolled his eyes and asked, "Can you give me a part?"

Yang Gan looked at Zhang Yumeng curiously, "What do you want the meteorite for?"

Zhang Yumeng immediately showed an angry look on his face, "Ge Zhao, this damn old man, he was treating the tenant farmers in Zhuangzi two days ago. I was curious, so I started chatting with him."

"He actually said that my surgery was witchcraft. He also asked me to read less books about witch doctors. He said that the witch doctors had separated."

"I really don't believe it. Brain surgery in the 21st century can't compare to his traditional medical skills."

Yang Gan scratched his chin, thought for a long time and said, "From a personal perspective, I still like Chinese medicine more, and I don't have a good impression of Western medicine."

"Do you have any prejudice against Western medicine?"

"Well, a little bit."
