When Han Gang and Zhang Dian were sent out of the restaurant by the shopkeeper of Xixi Building with a courteous face, it was already the beginning of the lanterns.

The afterglow of the setting sun has dissipated, but there is still a touch of deep purple with silken in the western sky, and the magnificent color is like Wu Aya from Huzhou, which does not need any pattern of patterns, it is comparable to the finest Shu brocade.

The street outside the Xixi Building is also a night market, although it is not as prosperous as the Zhouqiao Night Market, but the popularity is not much lost. When Han Gang stepped outside the building, he saw a lamp raised high, and the entire street was illuminated as if it were daytime, and there were more pedestrians on the street than during the day.

At the stall next to the restaurant, a brown-clad and felt-hat-clad vendor sang a merchant's tune and sold copper combs and hairpins to passers-by. The restaurant of this era was very tolerant of the vendor, and the vendor was sitting not far from the door, and no one came out to drive him away. Being in the market, and the goods he sells are somewhat attractive, his business is not bad, and he has five or six people around.

Han Gang stepped on the steps and walked out with Zhang Dian on his front and back feet, just glanced at the stall by the way, and his footsteps suddenly stopped.

"Han Xiao, you go buy a hairpin and come back."

The companion who was named by Han Gang was a little puzzled, this is obviously a low-grade goods for a few pennies, and he has no face to buy for his mother-in-law to wear, how can he give up people to buy it for the wife and the three ladies at home? But the doubts in his heart were doubts, he still obediently stepped forward and squeezed into the crowd, paid out of his own pocket, took nine yuan, and bought a hairpin without bargaining at all, and after thinking about it, he bought another copper comb back.

Presented the hairpin and comb to Han Gang, Han Xiao also babbled in pieces: "Why is the copper hairpin of this stall so cheap?" In the past, it took fifteen or sixteen to buy less. ”

Zhang Dian was waiting for Xiao Er of the hotel to bring his horse, and when he looked back at Han Gang, he was actually ordering someone to buy stalls.

"What's wrong?" He walked over strangely.

Han Gang didn't make a sound, and first scraped the surface of the hairpin with his fingernails, and saw that the copper color on it was still brilliant. He handed the hairpin to another companion behind him, and motioned for him to grind it on the ground a few times. I just sharpened it twice, and when the copper hairpin was brought back to my eyes, I immediately saw the silver iron inside.

"It's the copper immersion method." Han Gang showed the hairpin to Zhang Dan. He checked the copper comb in his hand again, and sure enough, the weight seemed to be a little wrong, far inferior to the similarly sized one he used at home in the old days.

The copper immersion method, that is, the replacement of copper in bile alum water with iron, is the content of basic chemistry. Nowadays, copper mines in the south are used a lot, and many of the pig iron produced in the southern Zhulu are made by this method. Although there are many people in the world who believe that this copper-making method is made of pseudo-copper, the rumors from the three divisions say that the copper immersion method will be vigorously promoted in the future, such as the copper mines in Jiangxi Lead Mountain and other places, will successively adopt this method.

Another place where the copper immersion method is used a lot is that it is used in the ordnance prison to plate iron with copper color. The plate armor taken out by Hangang during the Shangyuan Festival was plated with a layer of copper for the craftsman. In addition, almost no one uses it, and even few people know this method, and when the craftsman soaked the plate armor parts in copper, he once said to Han Gang that in addition to the craftsmen of the Ordnance Prison, there is no second craftsman in Tokyo who understands the copper dipping method.

But now it's only been a few months, and even the utensils sold at roadside stalls have used the copper immersion method, is it a coincidence, or did you learn it from the ordnance superintendent?

Han Gang's gaze turned to Zhang Tun's face, and Master Hanlin understood everything, indicating that he thought exactly the same as Han Gang.

Zhang Duan coughed, and the thing that appeared now also confirmed that the Ordnance Supervisor had become the focus of the world's attention, and some technical features would be stolen out immediately. It seems that he is not worried about Han Gang's words just now. "Yukun, what the foolish brother said today, I hope to think about it carefully." Zhang Dian said in a deep voice.

"Don't worry, Han Gang understands." Han Gang sighed softly.

It's a good thing that the technique is spreading, but the pressure on yourself is going to be great. But he doesn't need to worry too much about being in his current position, and it's a good thing that a little bit of a mistake has been made after the spaceship appears. And in any case, all his inventions don't have too much technical content, do you want to imitate them? One glance at the real thing is enough. The only thing that can give the imperial court an overwhelming advantage is scale. This is also the truth that Han Gang has always told Zhao Ji.

After saying goodbye, Zhangdun went to the east and Hangang went west.

The mount under him, with its hooves clattering on the ground, walked forward nonchalantly. This castrated Kasai horse was four feet two inches tall at the shoulder, just past the passing line of military horses, and was not a good horse—even a good horse would not be castrated—but it was honestly docile, even sluggish, and would not be as easily frightened as some other Hesai horses in the bustling city of Tokyo. Walk smoothly so that the rider on this horse will not feel difficult when driving.

Walking slowly westward along the South Gate Street, the bright purple on the canopy in front of me was gradually transforming into inky blue, and in the sky, the few scattered stars were still indistinct, but the sky was almost dark.

It was getting late, and I could already see the husband knocking on the bangzi in the alley on the side of the street, knocking every few steps. Han Gang lightly clamped the horse's belly and rushed home. Just arrived at Junyi Bridge and saw an acquaintance.

It is Wu Chong's second son Wu Anzhi, and in addition, he is also Han Gang's brother-in-law.

This Wu Anzhi got down from the Victory Bridge, his eyes swept left and right on the side of the street. It seems that at the same time that Han Gang saw him, he also discovered Han Gang. But looking at his attitude, he didn't seem to notice it, anyway, his eyes were blank, and he wanted to turn around and get on the horse. It's just that from Wu Anzhi's hurried attitude, Han Gang estimated that he probably still saw himself.

"Brother Nakayu!" Han Gang called out from afar. ran away when they met, Wu An's approach was too bad for him.

Wu An couldn't run away at this moment, so he had to get off the horse and turn back, with surprise on his face: "It turns out that Brother Yukun!" ”

"I haven't seen Brother Zhongyou for a long time, I don't know if it's always good?"

Stretching out his hand not to hit the smiling person, Han Gang walked up with a smile, and Wu Anzhi didn't want to leave after saying a few words, but he was pulled by him and talked on the side of the street for a while. Not only did he have to deal with Han Gang, but he also had to prevent being accidentally told something that shouldn't be said, and after only a few words of greeting, he was covered in sweat.

was delayed by Han Gang for a while, and even involuntarily agreed to come down and drink together another day, and when Wu Anzhi returned home, it was almost the second watch.

Walking into the room to greet his parents, Wu Chong asked unhappily, "Why did you come back so late?" But went to the Qinglou?! ”

Wu Anzhi didn't dare to hide it: "My son met Han Gang on the road. ”

"Han Gang?!" Wu Chong unexpectedly heard this name from his son.

"It's Han Gang." Wu Anzhi bowed his head and said, "He came up to talk to his son, and it was inconvenient to ignore him." ”

Wu Chong's face sank: "What did you say?" ”

"I didn't say anything, I just chatted for a while." Wu Anzhi saw that Wu Chong's face was full of disbelief, and hurriedly relayed the words he had said to Han Gang to Wu Chong.

Wu Chong listened to his son's babbling nonsense, and waved his hand impatiently, "You go down, and you will see Han Gang far away in the future." ”

"My lord......" Wu Anzhi didn't move, but called Wu Chong, who turned around and was about to enter the inner room to rest, with some hesitation......

"How?" Like most fathers today, Wu Chong is also like a strict gentleman at home, the former of the standard strict father and mother. Just a glance back with a slight frown made Wu Anzhi tremble.

"Why do you want to keep targeting Han Gang, isn't he just building weapons with peace of mind?" Wu An asked boldly, "Your opponent should be Lu Huiqing, why bother to have a grudge against Han Gang." Maybe now Han Gang is just a straight pavilion, but after a decade or two, he may not be able to rise to the East and West Mansions. ”

Wu Chong's eyes became sharp like knives and arrows, making Wu Anzhi's voice smaller and smaller, but listening to his son's words, he was silent. After a long while, Fang asked rhetorically: "What kind of heavenly son likes Lone Chen?" ”

“…… Don't form a party for personal gain, be loyal in things? Wu Anzhi's answer turned into a question sentence after the most lucrative one. cautiously raised his eyes to look at Wu Chong, waiting for the judgment of the answer.

Wu Chong was noncommittal, but asked again: "Have you ever seen a lonely minister as a prime minister?" ”

"Huh!?" Wu Anzhi was stunned when he heard this.

"Not a single one." Wu Chong smiled coldly, "Han Gang is not even affiliated with the New Party, and there is no one in the middle of the DPRK, how can he be promoted to the East and West Prefectures in the future?"

Wang Anshi has been an official for decades, although he has only served in the court for a few years. However, there are countless people who are close to the DPRK and China, and talent is also a temporary choice. Wen Kuanfu, Fu Yanguo, Ouyang Yongshu, Bao Xiren, how many important ministers and elders value him? Uncle Lu Hui, Lu Baochen, Sima Junshi, and even his father, how many friends have to sing and make peace with him? He is in Jiangning, and in his ears today, there are also Han Wei and Han Jiang who make the song of the war horse for him. No one in the government and the opposition praises it, Anshi can't come out, what is Nai Cangsheng?!

But look at Han Gang again, how many times has he participated in poetry meetings? Since you went to Beijing, how many scholars have you befriended? Several important ministers in the court, who did he personally attach? Even his father-in-law he ignored! Of course the Son of Heaven likes such a courtier. But if you want to be dominant, you can't think about it at all. The matter of Xuan Ma is not the sole decision of the Son of Heaven! ”

"But there is also Wang Shao in the two mansions. In Kansai, there is also a line of learning. Wu An argued in a low voice.

"Wang Shao's contribution is not small, but to expand the territory, the privy deputy envoy has reached the top, and there is no chance to take another step, what can he help Han Gang? Not to mention that if Guan Xue, but if Guan Xue has a little background, Zhang Zai will not always stay in Hengqu. Wu Chong sneered again, "If it weren't for Han Gang's disciple, his reputation wouldn't have spread to the capital for the rest of his life!" ”
