[I’ve been very busy at work recently, and my coding speed is very slow. After coding a few chapters every day, I don’t go to bed until three in the morning, and I have to get up at seven in the morning to send my son to kindergarten. It’s really fucking tiring. But look

I feel a lot better after receiving support from book friends. Thank you for your support! Thank you!]

Things have to be given away, but Xu Ziling is very interested in the technology of "Chixiao" that has been used for more than two thousand years and is still as bright as new and extremely sharp.

Looking at Chi Xiao's sharp blade, Xu Ziling remembered the word "blow the hair and make a decisive decision", so he pulled a hair from his head and prepared to experiment to see if the ancient casting technology was really that powerful.

Zhao Xueqin and Yang Ruolan watched Xu Ziling suddenly pull a hair from his head, and thought he was going to do something. When they saw him holding the sword horizontally and the blades facing each other, they knew what he was doing, so they were very interested.

Looking at him, I also wanted to know how sharp this sword was.

Gently holding his hair a few centimeters above the sword blade, Xu Ziling then let go and let his hair fall vertically. The hair touched the sword blade and was silently divided into two sections in the middle.

"Just make a decision." Seeing this, Yang Ruolan immediately shouted.

"Many of the swords forged today can make quick decisions, but it's really rare for ancient swords to be able to do this." Zhao Xueqin nodded and said.

Xu Ziling was about to say that this sword was superior to the current casting technology, when he heard the sound of the door opening, so he had to swallow his words and look towards the door.

The door opened, and four people, Yang Kaiming, Li Cheng, Liu Yiyi, and Tang Jing, appeared. As soon as they entered the door, Yang Kaiming saw a gleaming sword in Xu Ziling's hand, and said in surprise: "Hey, you never

Where did you get such a sword? Is it going to be given to grandpa? It looks like it probably cost a lot of money, right?"

When Xu Ziling heard this question, he just smiled and did not answer him. He just greeted a few people.

Liu Yiyi had been to the military villa many times when Xu Ziling and the others were away from Star City. Now they were not counted as guests. Several people greeted Zhao Xueqin, but Yang Ruolan couldn't bear it anymore.

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

"Tch, do you think your brother is a fool? Just by the look of this sword, I guess none of you can buy it for millions. Come on, show it to me." Yang Kaiming didn't believe that this sword belonged to Yang Ruolan and the others.

I bought it for 1,000 yuan. Just by looking at the appearance of the sword, I knew it was not ordinary, so I reached out to Xu Ziling and asked him to take a look at the sword.

When Yang Ruolan saw that Yang Kaiming didn't believe it, she simply didn't refute it. Thinking of the murderous intent on the sword, she just wanted to laugh at his joke.

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. Yang Kaiming suddenly felt a dangerous aura, which made his hair stand on end. "What kind of sword is this?"

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

"The Scarlet Sky Sword is one of the top ten famous swords in ancient times. It's just a matter of fact. We just tried it. You said we bought it for a thousand yuan, but you still don't believe it." Seeing Yang Kaiming's surprise, Yang Ruolan felt in her heart

He was so happy, but he didn't believe that they bought it for a thousand yuan.

Hearing what Yang Ruolan said, Yang Kaiming was even more surprised, "You really bought your relationship for a thousand dollars?"

"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. When they heard that it was a sword that Xu Ziling and Yang Ruolan bought for a thousand yuan, they immediately went to tell them how they came across it.

Such a good thing.

Picking up leaks was Yang Ruolan's happiest thing. When people asked about it, she told the process of picking up leaks twice vividly. After she finished speaking, other people could only say that they were very lucky apart from being envious.

"Find a thicker book and try this sword to see how sharp it is?" Yang Kaiming listened to what Yang Ruolan said, and he suddenly wanted to test the sharpness of the sword.

After saying that, without waiting for what others said, he ran into the study and found an old dictionary.

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

Uncovering the cover of the dictionary, Yang Kaiming held the sword, pointed the blade down, and pressed lightly on the paper. Because he knew the sword was very sharp, Yang Kaiming deliberately did not use much strength.

What he didn't expect was that even if he didn't use much effort, when the blade of the sword came into contact with the paper, it was like cutting into the air. There was no resistance at all, and the dictionary was cut open in one go.

Half of the paper.

Seeing it so sharp, Yang Kaiming hurriedly stopped his hand and took a breath of cold air: "So sharp? It's better than our best saber."

When several people nearby saw this, they were also shocked by the sharpness of the sword.

Xu Ziling was somewhat prepared, but he also did not expect that the sword could be so sharp, but Yang Kaiming's words also reminded him.

Yes, it can last for thousands of years without decay, so this material can be said to be too incredible. Although modern warfare can be said to be the era of hot weapons, for some special tasks and environments, cold weapons are absolutely useless.

replaceable.

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, 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 came out and wanted to consult Yang Kaiming and

Li Cheng’s suggestion.

"Ah..." After hearing Xu Ziling's words, Li Cheng was surprised at first, and then said: "This is a good idea. In many environments, cold weapons are better than hot weapons. If you can make it look like this sword,

, that’s another great achievement.”

"Yes, cold weapons are very useful for some troops." Yang Kaiming also nodded in affirmation.

"Okay, I'll go to the laboratory to take samples right away, and I'll find time to study it after the New Year." Xu Ziling saw that both of them said that his idea was feasible, and he immediately took the sword from Yang Kaiming's hand and said that he

Immediately go to the HKUST laboratory to take samples from the sword.

"Child, I'm not in a hurry to do this. I have to eat before I go. It will be lunch time soon." Zhao Xueqin saw Xu Ziling's excitement and said that he wanted to study this sword.

, I immediately thought about going to the laboratory to take samples.

Only then did Xu Ziling realize that he was at home, not when he, Yang Kaiming, and Li Cheng were outside together. He smiled awkwardly and said, "I forgot about it all of a sudden. I'll go there after lunch. Anyway,

Now we just need to take a sample and it will be done quickly."

"Okay, then when you go in the afternoon, bring something to Mr. Li and Mr. Huang to say goodbye. Ruolan, Xiaojing, Yiyi and we will go cook and let them chat here."
