Yan Xiao took out the mobile phone, called up a software, quickly entered a string of codes, and said: "The mobile phone has a built-in sensor that can analyze the composition of each position of Xuanyuan Sword, and then based on the composition, scrape off the patina bit by bit and make simple repairs.
.”
"It has this function?!" Wei Zi was surprised.
"Yes, there are quite a lot of functions built into the phone. I will tell you about them one by one when I have time."
Wei Zi: "..." If we had known that mobile phones could detect ingredients, we wouldn't have had to go through so many detours when making firearms in Yun State.
"Okay." The most important thing in front of him was the Xuanyuan Sword fragment. Wei Zi withdrew his mind, looked at Yan Xiao and took his mobile phone to analyze the composition of the fragment.
"That's wrong..." Yan Xiao felt strange.
"What's wrong?" Wei Zi asked.
"Here, you can see for yourself." Yan Xiao enlarged the detection results.
"Iron? How come there is such a high iron content?"
Wei Zi looked at the fragments strangely. In modern times, she had personally handled unearthed Shang and Zhou bronzes, which looked similar to this one.
According to records, the Xuanyuan Sword was cast from the copper ore collected by the Yellow Emperor from Shoushan, which is also in line with the level of weapon manufacturing in ancient times. From Yao, Shun, and Yu to the Xia, Shang, and Zhou dynasties, bronze casting was the main method.
Bronze is an alloy with tin or lead added. It does not contain iron itself, but a certain amount of iron will be infiltrated due to the surrounding environment, but that is only a trace amount.
The earliest iron smelting tools appeared in the Western Zhou Dynasty. Before that, in the Shang Dynasty, although there were iron tools, they were meteorite...
Wei Zi's eyebrows skipped a beat.
siderite!
Wei Zi took a closer look at the ingredient list on her phone. In addition to iron, there were indeed nickel and cobalt content. Although it was very low, it was enough to prove that this broken sword was made of meteorite.
But why is there no rust?
Yan Xiao also discovered this problem: "Copper will have patina, iron, then it should have rust..."
"Could it be a double-layered sword?" Wei Zi made a bold guess.
Seeing that both Yanxiao and Feng Danyuan were waiting for her words, she did not give in. "In ancient cultural relics, sometimes in order to hide the real thing, an imitation will be put on the outside. This kind of thing is very common. I suspect that this sword, outside
Covered in bronze, but inside is an iron sword.”
"It's possible." Yan Xiao agreed.
"However, double-layer casting requires very high craftsmanship. Did Huangdi have such a high level of smelting at that time?" Wei Zi wondered.
"Don't forget, that was an era when gods, demons, and witches were fighting each other. There were things that humans couldn't do, but divine power could." Feng Danyuan said.
"It makes sense." Yan Xiao tilted his head to confirm Feng Danyuan's reason.
After Wei Zi was startled, he nodded.
As soon as she entered the field of science, she almost forgot that since her time travel, many things could no longer be explained by science.
"If it is as we have guessed, then these are most likely fragments of the Xuanyuan Sword. Bronze and meteorite-iron swords belong to the technology of ancient times, and double-layered swords can only be made by divine power or the power of witches and demons.
The patterns on the sword are also consistent with ancient book records." Wei Zi said.
"Then do you need to take out the iron sword inside to seal the magic sword?" Yan Xiao asked.
Wei Zi shook his head: "I don't know, I have to ask Linze about this."
Yan laughed and said nothing.
"Then go find him." Feng Danyuan said.
Wei Zi nodded: "Let's go."
"Wait a minute -" Yan Xiao gritted his teeth and said, "Let him come. If he comes here, you won't do anything to him, but if you go over, he might be able to do it."
She said tragically to Wei Zi: "Didn't he say that he wanted me to be a mouthpiece? I'll do it!"
