"Is there anything wrong with rust?"

Seeing Qian Lao's movements, Yu Feibai asked very smartly.

"It's hard to say, let's take a look first." Qian Lao said casually, and then carefully observed the reaction of the rust shavings in the hot water, only to see that the rust shavings quickly dissipated, dyeing the clear boiling water into a yellow-red turbid color.

At the right time, Yu Feibai touched Wang Guan and asked quietly, "This should be considered a normal situation, right?" ”

"I don't know, I'm not good at chemistry." Wang Guan shook his head blankly, and he didn't quite know if this would happen after the rust chips melted in the hot water.

"Liberal arts students are weak ......"

Noticing Wang Guan's glance, Yu Feibai said angrily: "I didn't say you, it's not okay to laugh at yourself, I'm also a liberal arts." ”

Wang Guan couldn't help laughing, and didn't bother to pay attention to Yu Feibai, but turned his head and asked, "Old Qian, this rust seems to be a little weird." ”

"Oh."

At this time, Qian Lao said with interest: "What's weird? ”

"You're always testing me again."

Wang Guan said cautiously: "I saw very clearly just now, you threw a few small pieces of rust into the hot water. In general, the rust flakes should contain iron so that they don't melt so quickly. But now, as soon as the rust flakes are thrown into the cup, they seem to quickly disperse. ”

"Huh."

At this time, Yu Feibai also woke up and said: "It's really wrong, I have studied the rust spots on the sword, although there are rust chips falling, but in general, it should be very strong, how can it be scattered when it encounters water?" ”

Wang Guan nodded slightly, agreeing with Yu Feibai's words. After all, he had also checked, and the rust spots were indeed firmly attached to the sword, giving people the feeling that they were stubbornly stained and could not be cleaned and scraped off. At the beginning, he was still thinking about whether to polish it, but he didn't expect that it could be soaked with high-temperature hot water.

Of course. After discovering this situation, Wang Guan was also very pleased. After all, grinding is risky and will leave some grinding marks on the blade. Being able to resolve the rust marks on his sword with relative effortlessness was an unexpected surprise to him.

Sure enough, at the critical moment, Qian Lao is still reliable.

"Qian Lao, can this rust be washed with hot water?" Yu Feibai was very surprised, and he picked up the kettle and was about to go to fetch water to boil.

"It's not that simple."

However, Qian Lao shook his head slightly: "These rust spots have been solidified for at least a thousand years, and they can't be easily dispersed." High-temperature hot water is useless, high-temperature spirits are needed. ”

"Spirits?"

Moment. Wang Guan and Yu Feibai were a little surprised.

"Old Qian, does this method work?" Yu Feibai was naturally a little skeptical: "I haven't heard that you can remove rust with spirits." ”

"What does Qian Lao say, then do it." Wang Guan groaned: "Besides, the rust spots on the ancient sword don't seem to be rust in the real sense, or there are some differences from ordinary rust. ”

"You see that?" Yu Feibai was stunned and said, "What's the difference?" ”

"I don't know, if you ask Qian Lao, I'll go buy spirits first."

While speaking, Wang Guan hurriedly went out and returned with a case of high-grade liquor at a nearby store. found that during the time he went out, Qian Lao and Yu Feibai had already set up a stove on the floor of the mansion, and put a cauldron on it, waiting for his spirits.

See this. Wang Guan was a little surprised: "Is this to boil wine, or to boil the sword and wine together?" ”

"Cook the wine first." Qian Lao thought for a while and said with a smile: "Polishing the sword with high-temperature spirits, if it still doesn't work." That's like you said, put the sword in the pot and boil. ”

"Stop talking nonsense."

At the right time, Yu Feibai was a little excited. Hurriedly urged: "Hurry up and help pour the wine." ”

As he spoke, he opened the two bottles of liquor, picked up one in one hand, and then tilted it slightly towards the cauldron, and the pungent aroma of wine flowed out from the mouth of the bottle, so that the people next to him couldn't help but move their noses.

Wang Guan went up to help, and with little effort, he poured half a box of liquor into the pot. Then it was boiled over a fierce fire, and after only a few minutes, wisps of steam came out, and for a while, the house was full of wine, very rich and attractive.

The aroma of the wine is tempting, but this is a very high degree liquor, which hurts the body and throat very much, and ordinary people can't bear it. Especially after steaming, the characteristics of the spirit are fully brought into play, and I am afraid that it is easier to get intoxicated.

It is common sense that warm wine is easy to get drunk. But now everyone cooks sake, and it's not for tasting. Seeing that the liquor in the pot was already boiling, Qian Lao immediately dipped the prepared white gauze into the pot.

The gauze was soaked with liquor, and Qian Lao pulled it out again, quickly folded it into a block, and then carefully brushed it over the body of the sword. With a gentle wipe, the white gauze was immediately stained with large patches of red and yellow rust.

This is a very normal situation, Wang Guan and Yu Feibai will not care, they just observe carefully. I saw that under Qian Lao's wiping, the thick rust on the sword body really showed signs of melting, and it was peeled off little by little......

As time progressed, Qian Lao changed seven or eight strips of white gauze in a row, and the rust spots on the ancient sword became fewer and fewer, leaving only a shallow layer. In this process, everyone also witnessed the ancient sword slowly evolve from a mottled appearance to a very beautiful and charming situation.

If the ancient sword was still an ancient sword before, then now that most of the rust spots have been cleaned up, this sword looks like a new sword has been put on the shelf for more than ten years. A thousand-year-old sword has become what it is now in a short period of time, which is definitely a great improvement.

In addition, after the thick rust was removed, the inscription on the sword body was gradually revealed.

"What is Jianming?"

At this time, Yu Feibai was very excited and hurriedly came closer to watch. However, it is a pity that although the thick rust is gone, there is still a thin layer of rust on the sword.

This layer of rust film can't be wiped off, just like a piece of clothing that has been worn for several years, even if it is cleaned every day, but there are still some dark yellow stains left in the collar. This is the most stubborn stain that will not be washed away no matter how much you rub it.

It is this layer of rust film that makes the inscription blurry and looming, giving people the feeling of seeing flowers in the fog.

"This is the seal ......"

Yu Feibai opened his eyes wide and tried to observe, and even reached out to touch it with his fingers. However, because the inscription is relatively simple, although he feels that the text is very similar to Chixiao, he is not sure.

is still the same sentence, although the ancient sword has changed its appearance now, showing a bit of extraordinary temperament. However, there is still a big gap with the legendary Chixiao Famous Sword.

"This sword looks pretty good, maybe it was a famous sword in the past, but it is definitely not Chixiao, at least the two seal characters are not like ......" Yu Feibai analyzed, but his confidence was a little insufficient.

"Don't be stubborn, this sword is absolutely blazing." Wang Guan retorted, and frowned slightly: "But this layer of rust film is really more eye-catching. Qian Lao, can't you solve it? Do you really want to polish it? ”

"You can't grind." Qian Lao shook his head without hesitation: "A grinding destroys the ancient beauty of the sword, in fact, this is also very good, the light is restrained, unpretentious." Now it's a new rust, and after a while, the sword body has adapted to the surrounding environment, and maybe a ghostly light will emerge. ”

The so-called acclimatization should refer to the process of re-oxidation. Or it means that Wang Guan often plays with it, so the sword body naturally forms a pulp. However, no matter which possibility it was, it did not meet his psychological expectations.

At that moment, Wang Guan's eyes flashed, and he hesitated: "Old Qian, if you say that you cook it directly, can you dissolve the rust film?" ”

"Maybe ......"

Qian Lao said uncertainly: "But you should also understand that the liquor itself has a certain degree of corrosiveness, although it is very small, but after heating at high temperatures, especially if the sword is put in a pot to cook, it may have some impact on the sword body." As for whether it is a good influence or a bad one, it is somewhat out of control. ”

"It's very likely that the rust film will be dissolved, and it may also be that the stability of the sword body may be destroyed......"

Qian Lao reminded with a smile: "You think clearly, if it is the former, everyone will definitely be happy." If it's the latter, I don't know what this sword will become. ”

"Old money."

Wang Guan pondered for a moment and simply asked, "What do you think of it?" Also, what about this rust stain, I never know, can be wiped off with spirits. ”

"Hehe......"

At the right time, Qian Lao smiled lightly, and without waiting for Wang Guan to choose, he directly put the long sword in the cauldron, and then closed the lid of the pot, leaving only half of it outside the pot.

"Old Qian, you are ......"

Suddenly, Wang Guan was very surprised, and then he was a little happy and said, "Do you think that this is the Chixiao Sword?" ”

"I don't know."

Qian Lao smiled lightly: "It will take a while to know the result." ”

"Old Qian, you have said so, then the result must be nine out of ten." In an instant, Yu Feibai's spirits perked up, and he paid close attention: "After boiling the rust film, will it restore the brilliance of the Chixiao Sword, and the appearance of the blade like frost and snow?" ”

"It's hard to say." Qian Lao groaned: "I just know that there is indeed a problem with the rust spots on the sword. It wasn't an ordinary metal rust mark, it was blood rust......"

"Bloodrust?"

At first hearing these words, Wang Guan and Yu Feibai were inevitably a little surprised, and felt a little frightened.

"What is blood rust, rust that turns into blood?" Yu Feibai speculated: "The blood coagulates on the sword, and then after a long period of oxidation, it becomes a layer of rust spots?" ”

"That's right." Qian Lao nodded and said, "It depends on the situation." ”

"Is Bloodrust's attachment so strong?" Yu Feibai was still a little strange: "It's so thick...... How much blood does it take......"

"Wait!"

Suddenly, Wang Guan remembered and said with a strange expression: "Old Qian, you seem to have said that the reason why Chixiao is called Chixiao seems to be due to the adsorption force of the sword pattern......

The subtle sword patterns of the Gongbu sword can firmly adsorb the water on the sword body and not drip for a long time. If the Chixiao Sword's adsorption capacity was even better, condensing the blood like an appendage, it wouldn't seem like a strange thing.

At the same time, Wang Guan also vaguely understood why it was recorded in some documents that the Chixiao Sword needed to be sharpened in twelve years. Grinding is not necessarily polishing, but it may also be cleaning blood stains...... (To be continued......)
