Chapter 403: There Are Titans in the North, Overtaking the Tigers in the South, and Wizards in the South

King Jian'an, Mu Jisheng!
One of the most mysterious hole cards of the Mu family.

When he came to accompany Smiley at this time, it was naturally not because An De had any kind intentions, but just because he didn't want to make things worse and let people calm down.

"King Jian'an, if you say that, you are a junior."

Qingyun was still holding the stem in his hand, and his guard posture did not change at all.

It's not that he's afraid of King Jian'an's sudden move, it's just an attitude, an attitude that draws a clear line.

"Oh?" King Jian'an did not declare his title, but the young man in front of him was able to tell the truth, obviously a well-informed person.

According to etiquette, people usually mention that he can only be called King Jian'an and hide his name.

It is not unusual to know that the army of King Jian'an is coming.Knowing that King Jian'an is Mu Jisheng, he must not be an ordinary man.

King Jian'an couldn't help but look at Qingyun a few more times, "Which mighty seat of the Taoist sect is this young man worshiping?"

"The wind, cloud, thunder and lightning know what I want, and the ancient Sanqing is my teacher. The six desires and seven emotions are all entered into the sword, and everyone laughs at me as a martial arts idiot."

Qingyun has seen many fake Taoist sects with "Tao bone fairy style".In order to look more like the real thing than the real thing, they like to make some mysterious opening remarks.

Qingyun's whim was a small test, and it was tantamount to giving King Jian'an a soft nail, and ignored his question directly.

But in fact he did not lie, Qingyun is neither a member of the Taoist sect nor a master in the true sense.Self-confessing that the ancient Sanqing is my teacher, can only be regarded as a joke at best.

These words were very harsh to King Jian'an's ears. Since the visitor knew his identity, he still made a fuss in front of him and said something disrespectful.

But the more Qingyun was like this, the more King Jian'an didn't dare to attack.

Could it be that this bastard was specially placed here by the King of Wei to test my mind?

King Jian'an thought so.

So instead of being angry, he deliberately used layers of wrinkles to put an awkward smile on his face, "Such courage, indeed! There are three cleans in the fairy world, and the emperor is respected in the world. The young hero is indeed extraordinary, dare to ask your name taboo ?”

"Up to Qing and down to the clouds."

"Qingyun, um, okay..." King Jian'an muttered the name, suddenly seemed to realize something.

Boom, a beard was directly cut off by his bearded hand, and he didn't realize it, but there was already a huge wave in his heart,

"Qingyun? It's the pawn that the military master missed before! I thought he would assassinate King Wei because of his father's revenge, but he ended up standing in front of King Wei? Yes! That's the name. He really is King Wei people!"

Qingyun has never been a person who likes to cause trouble, but he is a very meticulous person, that's why he took the initiative to provoke King Jian'an today.Every little movement and micro-expression of the other party fell into his eyes.

"This person has indeed heard of my name. He was puzzled, hated, fearful, and a little bit sorry for me. Well, the five-way prison dragon operation that the Mu family participated in was planned by Tianzong behind the scenes. There must be a connection with Tianzong, this old guy, I have to keep an eye on him!

Wait, the puzzled and confused emotion on his expression has overwhelmed everything else, and it's about to overflow!Why?I shouldn't have aroused his great interest... Could it be that what he saw was..."

Qingyun turned his head slowly.

Sure enough, Hu Caiting and Yin Seke also poked their heads out to watch the excitement.

"King Jian'an recognized someone among them..."

Regarding this point, Qing Yun was not surprised at all.

But just when he was about to say something to test the old fox, he suddenly faltered.

"It's really reckless of us to disturb Qing Shaoxia. You are busy first, and I will make room for the two female relatives later. Farewell..."

King Jian'an came to greet him imposingly, and ran away in a despondent manner, which made Qingyun also look confused.

It was obviously not himself that Mu Jisheng was afraid of.

Could it be... among the two, Senior Sister Hu and Miss Yin, there is an existence that the Mu family fears?

Seeing that the Mu family's army had all retreated, Liu Ying, Dianzhi and Qingyun looked at each other for a moment, then withdrew their swords and retreated into the room.

"Fifth brother, your tone of voice today is a little strange, but what's wrong?"

Liu Ying knew his adopted brother very well, and he was rarely so eccentric in the past.

"Back then, the Mu family was on the side of Tianzong in the Battle of the Five Route Prisoner Dragon. This time they brought so many masters here, and their purpose may not be simple."

When Jing Qingyun mentioned it, Liu Ying seemed to have sensed something was wrong.

"That's right, they had four masters attacking me just now, and none of them is inferior to Tian Nu of the Snake Villa. And the aura of King Jian'an himself seems to be stronger than those four... Their juniors can't tolerate it either." Xiao Wang, Mu Changcheng, who made phoenix wings boring, is at least at the level of land slaves. The hundred or so people brought by the Mu family are no less powerful than Wei Wang's servants. However, they really dare to pray for the new year. Do it at the ceremony?"

"I don't know. I feel that Tianzong will definitely not let the grand ceremony be peaceful." Qingyun hissed lightly, and there seemed to be a bit of worry between his brows.

Bang, bang, bang.

The sound of knocking on the door is just right and rhythmic, which reflects the politeness of the descendants.

Qingyun opened the door, and when he saw Mu Changcheng's condescending attitude, he was still not used to it.

"Several heroes, I'm sorry, I'm sorry! I was impulsive just now. There are three rooms in this courtyard, and we have already packed them all. Two of them are reserved for you, and there is another one. Later today, there will be distinguished guests. Greet you in advance."

"Oh?" Qingyun glanced at the two sides, one door, three rooms, a classic layout across courtyards.

People's hearts are like this, although one room is enough, but once you get two rooms, one of the three rooms is an outsider.

"Where is this distinguished guest? There is no other meaning, just ask casually, after all, he is going to be a neighbor for a few nights." Qingyun smiled.

"Understood, understood! I heard from the elders that the other room is reserved for the prince of Song Dynasty." Mu Changcheng smiled all over his face, answering every question, and his attitude was extremely good.

"Song Wang's son?" Qing Yun's mind jumped out of the sick Liu Chengwu.

The king of Song is also the king of the opposite sex in the Wei Dynasty, so there is nothing wrong with attending the prayer ceremony.

But King Song has been missing since he was injured in a sword fight with Qiongqi, and no one knows where he is now.

It is also reasonable for Song Wangshizi to replace his father and his party.

Before Qingyun Baishan and his party, he didn't feel anything strange, but now he remembered what Chentangguan Li Jing once said:
If you want to become a Heavenly Venerable, you must at least be the overlord yourself, as high as a prince.

King Song was once the emperor of the Southern Dynasty.

Tianzun's whereabouts are secretive, and King Song's whereabouts are also uncertain.

Could it be...

"""""Knock on the blackboard time"""""

In this chapter, we use the blackboard time to repay the debt, so it may be a bit complicated.

In Chapter [-], there are still a few knowledge points left.

Among them, ghost hair lead refers to needle nickel ore, which is shaped like hair and can appear golden yellow, green or even tinted (colorful). There are rich ore in the Hexi (Gansu) Guanzhong (Shaanxi) area of ​​China.The main component of goethite is nickel sulfide, which has active chemical properties, and the possibility of direct nickel production by reduction method is very high.

Regarding the ancient zinc production, we have roughly talked about it. In the Ming Dynasty science and technology book "Tiangong Kaiwu", there is a very detailed introduction to the preparation method of Japanese lead (zinc).This method of reducing zinc from calamine by means of sealed distillation has been well defined.Moreover, the archaeological community has also discovered a large number of Ming Dynasty zinc kilns, which are based on the same method.Therefore, scholars concluded that the purification of metal zinc in China began in the Ming Dynasty.

In fact, this conclusion is somewhat arbitrary, because as early as the Five Dynasties Xuanyuanshu's "On Treasures", it was proposed that "Japanese lead can hook gold", which was quoted in "Compendium of Materia Medica".Some scholars once questioned that the Japanese lead here is not the same as the so-called Japanese lead in the Ming Dynasty.But don't forget that the saying "Japanese lead can hook gold" refers to a common sense of physics that China has mastered for more than two thousand years-zinc can turn copper into gold.Interpreted in combination with the meaning, it is somewhat inappropriate to translate Japanese lead as any other metal.

If someone thinks that the author's point of view is too radical and arbitrary, then maybe another example will be cited, and the result will be clearer:
"Kangxi Dictionary" 鍮 note: "Jade", 鍮 stone like gold. (Jianshi is wild brass.) Later, there is another article: "Gegu Yaolun" Zongshi, the essence of natural copper.Today, those who refine calamine are fake 鍮.Cui Fang said: "One catty of copper and one catty of calamina can be smelted into calamine stone."

Calamine is exactly the zinc mine chosen for the zinc smelting in "Starting the World".Cui Fang, a Danshi in the Northern Song Dynasty, wrote "Wai Dan Materia Medica", and its time is not much different from that of the Five Dynasties.He very clearly described the detailed method of co-smelting fake gold from copper and zinc mines, "Japanese lead can hook gold".The copper here is already prepared copper, and co-smelting with calamine is the process of refining calamine into zinc and then mixing it with copper.The chemical change involved in this process is zinc production.

Because this example was recorded in the dictionary and the book "Wai Dan Materia Medica" was lost, metallurgical scholars did not pay attention to it, and it was rarely used to discuss the understanding of zinc (Japanese lead) in ancient China.

There is another similar example in the Southern Song Dynasty. Dai Tong's "Six Books Gu" said: Lvlugan stone was smelted into copper to make 鍮.

Xuanyuanshu, Cui Fang, and Dai Tong told us that Chinese alchemists have long since figured out the physical and chemical properties of zinc.As the civilization with the longest duration of bronze culture, China has far surpassed other civilizations in the world in its research and summary of copper alloys.

From discovery, control, to understanding, is a long process.Therefore, the discovery and use of zinc in China should actually be much earlier than the Five Dynasties.

We then verify the technical feasibility.The reduction of zinc by the sealed distillation method requires a high temperature of 900 degrees, which is far lower than the temperature required for steel smelting.The indigenous method of kiln steelmaking has been mastered by the Chinese as early as the Spring and Autumn Period, and the earliest unearthed steel sword identified as steel is the Spring and Autumn Bronze Steel Sword.

Near Sweden, a sunken Chinese ship was once salvaged, full of porcelain and zinc ingots.The shipwreck dates from the late Ming and early Qing Dynasties. The zinc ingots were all cast in China, and the characters Fan (mold) were engraved in Chinese. Its purity was as high as 99%, which was crushed by the zinc purification process in Europe at that time. (Special note: The author did not find absolute evidence for this example. However, Wikipedia quoted it with links to related reports, and Baidu Encyclopedia quoted it and included it in the entry "Ancient Zinc-making Technology".) It can be seen that China was once the center of the world's zinc-making industry , high-purity products are exported to Europe and are as popular as porcelain.

Zinc, even if this metal can be purified, it is not suitable for direct use as utensils.Regardless of hardness and density, it is not an irreplaceable metal, nor is it easy to prepare in ancient times.Its main significance lies in electrochemistry.This is the so-called thunderbolt method in this article.

How the thunderbolt method is realized will be discussed in detail later in the plot.

Dingqin ancient sword, the name of the sword can be found in Tao Hongjing's "Ancient and Modern Sword Records": Qin Shihuang, reigned for 37 years.At the age of three years, Dingsi picked up a piece of northern copper and cast two swords, named Dingqin, small seal script.Li Si was buried next to the Efang Palace, and the other was under the viewing platform, which was three feet and six inches long.

In the archaeology of the Qinling Mausoleum, a bronze sword was unearthed in Pit No. 2000, which has been recognized for [-] years and easily cut through twelve layers of newspapers.Tested to have a chrome-containing protective layer attached.How to complete a similar protective layer method, modern experts can only guess and dare not make a conclusion.

The author is also willing to make a bold guess, what if, right?

This book combines these two pieces of cold knowledge, collectively known as the thunderbolt method to formulate Qin Gujian, that is, the use of ancient scientific and technological conditions to restore the electroplating process mentioned in the preface of this book, which will be expanded in subsequent chapters.

In the book, the crossbow jointly designed by Zu Chongzhi and Tao Hongjing utilizes many black technologies.For example, the spirit level, in fact, the ancients have known this thing for a long time.Level, level, the word, speaks to the existence of a similar design.Wind compensation, distance measurement and parabolic compensation are also very easy to understand.

What is more difficult to understand is why the sniper mode of the crossbow needs to add a long handle~ This is actually a hydraulic transmission method, which is the principle of a [-]-ton hydraulic press.Through the long stroke of the thin tube, the huge pressure of the short stroke is generated in the thick tube. The hydraulic elevator in the Tongren Maze is also based on a similar principle.

Bows that cannot be drawn by manpower can be wound by hydraulic presses.However, it takes several times to complete the long-stroke movement, so there will be a hydraulic transmission device similar to the length of a rifle to assist winding.This is to highlight the tension of the string to explain why there is a crossbow with an effective range that exceeds that of the bow.
