[I've been very busy at work lately, and my code speed is slow, and after a few chapters a day, I don't sleep until three o'clock in the morning, and I have to get up at 7 o'clock in the morning to send my son to kindergarten, which is really fucking tired. However, seeing the support of book friends, I feel a lot better, thank you for your support! Thanks! 】

Things are to be given away, but Xu Ziling is very interested in the technique of "Chixiao" that has been as bright as new and extremely sharp after more than 2,000 years.

Looking at Chixiao's sharp blade, Xu Ziling remembered the word "nitpicking", so he pulled a hair on his head, ready to experiment, to see if the ancient casting technique was really so powerful.

Zhao Xueqin and Yang Ruolan watched Xu Ziling suddenly pull a hair from the top of his head, and thought that he was going to do something, but when they saw him hit the sword horizontally and the blade was on the front, they knew what he was doing, so they looked at him with interest, and also wanted to know how sharp the sword was.

Gently pinching his hair, a few centimeters above the blade, Xu Ziling then let go and let the hair fall vertically, and the hair touched the blade, silently splitting into two sections from the middle.

"Nitpicking." When Yang Ruolan saw this, she immediately shouted.

"There are a lot of swords that can be made now, but it's really rare for ancient swords to be like this." Zhao Xueqin nodded and said.

Xu Ziling was about to say that this sword was higher than the current casting technique, when he heard the sound of the door opening, so he had to swallow the words back and look at the door.

The door opened, and four people appeared: Yang Kaiming, Li Cheng, Liu Yiyi, and Tang Jing. As soon as he entered the door, Yang Kaiming saw Xu Ziling holding a cold sword in his hand, so he said in surprise: "Hey, where did you get such a sword?" Ready to give it to grandpa? I guess it cost a lot of money, right? ”

When Xu Ziling heard him ask, he just smiled and didn't answer him, just greeted a few people.

Liu Yiyi had been to the villa of the military region many times when Xu Ziling was not in Star City, and now they are not considered guests, and a few people greeted Zhao Xueqin, and Yang Ruolan couldn't help it.

"Brother, this is what we bought back today for 1,000 yuan."

"Che, do you think your brother is a fool? Just looking at the appearance of this sword, you must not have a few million that you can't buy. Come, show it to me. Yang Kaiming didn't believe that this sword was bought by Yang Ruolan and them for a thousand yuan, just looking at the appearance of the sword, he knew that Lu Dao was not ordinary, so he stretched out his hand to Xu Ziling and asked him to take the sword and take a look.

Yang Ruolan saw that Yang Kaiming didn't believe it, she simply didn't refute it, thinking of the murderous aura on the sword, she wanted to see his jokes.

Xu Ziling held the sword and pointed the hilt at Yang Kaiming, "Be careful, hold the hilt, this sword is very sharp." ”

The sword was still dozens of centimeters away from Yang Kaiming's hand, and Yang Kaiming suddenly felt a dangerous aura, which made his cold hair stand up, "What kind of sword is this?" ”

Of course, murderous aura is very sensitive to soldiers, Yang Kaiming could see at a glance that the murderous aura was emanating from the sword in front of him, so he asked in surprise.

"Chixiao Sword, one of the top ten famous swords in ancient times, but it's nitpicking, we just tried it. I said that we bought it for a thousand dollars, but you still don't believe it. Seeing Yang Kaiming's surprise, Yang Ruolan felt happy in her heart, who made him not believe that they bought it for a thousand yuan just now.

Hearing Yang Ruolan say this, Yang Kaiming was even more surprised, "Is the relationship really bought by you for a thousand yuan?" ”

"Yes." Xu Ziling nodded.

When several other people saw Yang Kaiming's appearance, they all came over and gathered around to look at the sword, and when they heard that this was a sword bought by Xu Ziling and Yang Ruolan for a thousand yuan, they were about to go and tell them how they had encountered such a good thing.

Picking up the leak is the happiest thing for Yang Ruolan, as soon as everyone asked, she said the process of their leakage twice, and when she finished speaking, others could only say that their luck was too good.

"Find a thicker book to try this sword, how sharp is it?" After Yang Kaiming heard Yang Ruolan finish speaking, he had a whim to try the sharpness of the sword.

After saying that, he didn't wait for anyone else to say anything, he ran into the study and found an old dictionary to come out.

Everyone was also curious about how sharp the sword was, so they all watched his movements.

Uncovering the cover of the dictionary, Yang Kaiming took the sword, put the blade down, and pressed it lightly on the paper. Because the Zhilu Dao Sword was very sharp, Yang Kaiming deliberately didn't use much strength.

What he didn't expect was that even if he didn't use much strength, when the blade of the sword touched the paper, it was as if it was slashing into the air, and there was no resistance at all, and a dictionary would cut half of the paper in one fell swoop.

Seeing that it was so sharp, Yang Kaiming hurriedly withdrew his hand, and gasped in his mouth: "So sharp? Better than our best sabers. ”

When the few people next to them saw this, they were also startled by the sharpness of the sword.

Xu Ziling was a little prepared in his heart, but he also didn't expect that this sword could be so sharp, but Yang Kaiming's words also reminded him.

Yes, it can go through thousands of years without decaying, then this material can be said to be too rebellious, although modern warfare can be said to be the era of thermal weapons, but for some special tasks and environments, cold weapons are absolutely irreplaceable.

Is it possible to study this sword and create a batch of special cold weapons? Xu Ziling was thinking about it.

"Brother Kaiming, Brother Chengzi, you say, what if I restore the forging process and materials of this sword and use it to make a batch of sabers?" With this plan, Xu Ziling said it and wanted to ask for the advice of Yang Kaiming and Li Cheng.

"Ah......" Li Cheng was surprised when he heard Xu Ziling's words, and then said: "This idea is good, in many environments, cold weapons are better than hot weapons, if you can make it like this sword, it will be a great achievement." ”

"That's right, cold weapons have a great effect on some troops." Yang Kaiming also nodded in affirmation.

"Okay, I'll go to the lab right away and take samples and take time to study it after the next year." Xu Ziling saw that both of them said that his idea was feasible, so he immediately took the sword from Yang Kaiming's hand and said that he would immediately go to the laboratory of the University of Science and Technology to sample the sword.

"This kid, this matter is not in a hurry, if you want to go, you have to eat and go again, it will soon be lunch time." Zhao Xueqin saw that Xu Ziling was in a hurry, and said that she wanted to study this sword, and immediately thought about going to the laboratory for sampling.

Xu Ziling then thought that he was at home, not when he was outside with Yang Kaiming and Li Cheng. smiled awkwardly, "I forgot all of a sudden, then I'll go again after lunch, anyway, as long as I take samples now, I can get it done soon." ”

"Okay, then you can bring something for Li Lao and Huang Lao when you go in the afternoon, which can be regarded as an early visit. Ruolan, Xiaojing, and Yiyi went to cook for us, and let them chat here. Zhao Xueqin heard that Xu Ziling would go to the University of Science and Technology in the afternoon, so she asked him to bring something for Li Lao and Huang Lao, and then took a few girls to the kitchen and began to cook.
