The carriage drove to the palace, and the father and son went to contact the emperor.

Zhu Ming fiddled with a Rubik's cube and said with a smile: "Dean Zhu, how boring are you in Tokyo?" Not only did he get out of the telescope, but he also got out the Rubik's Cube. ”

"It's actually quite simple," Zhu explains, "first make a central shaft out of wood, and then make the springs by hand." In fact, the spring can be left out, and it is more difficult to assemble. Screws are also not necessary, they are fixed directly with nails and wooden plugs. Then use wood to grind the tracks, and the wooden blocks of each layer can be moved, and the middle is also smeared with cooked tung oil for lubrication. ”

"That's not the point," Zhu Ming said, "the point is how do you know the internal structure of the Rubik's Cube?" ”

Zhu Guoxiang said: "I had a roommate in high school, and I had some overseas connections at home. When a relative returned to his hometown to visit his relatives' graves, he bought a television set for his home and a Rubik's Cube toy for each child. I don't give a manual, I don't know the formula of the Rubik's Cube at all, and my roommate can't get back to the right for a long time, so I simply dismantle the Rubik's Cube and observe the internal structure. ”

Zhu Ming complained: "I can't play the Rubik's Cube, but I know how to dismantle the Rubik's Cube?" ”

"Normally, it's easy to dismantle, and you can pick it off by turning the top layer," Zhu Guoxiang said, "I asked the carpenter to do this is not easy to dismantle, there are no screws, and it was nailed down during installation." ”

Zhu Ming asked, "What did your roommate do later?" ”

Zhu Guoxiang said: "I studied civil engineering, and later became a bridge expert. ”

Zhu Ming suddenly asked: "Dean Zhu, you even know the internal structure of the Rubik's Cube, how much do you know about earth-based steelmaking?" ”

Zhu Guoxiang said: "When I remember, I didn't make steel for a long time. I heard from the elders that that thing was useless, and it was purely to deal with the errands. Do you want to make steel? ”

"Half of my knowledge of smelting steel comes from Tiangong Kaiwu, and half from CNKI papers," Zhu Ming said. It seems to be very powerful, but I only know a name, and I have a general shape, so I don't know exactly what it is. ”

Zhu Guoxiang asked: "What are the records of "Heavenly Creations"? ”

Zhu Ming said: "The first is to improve the steel frying method, string the iron-making furnace and the iron-frying furnace, and combine the two processes into one. When I was in Puzhou, I inquired with a blacksmith, and the iron-smelting yards all knew how to fry steel, but the iron-making and iron-frying processes were separated. If they can be combined, the smelting efficiency will increase exponentially. ”

"The second is to improve the steel-filling method, no longer sealing the furnace with soil, but covering it with mud-coated broken straw shoes, which can make the steelmaking furnace continue to obtain oxygen and melt the pig iron in a reducing atmosphere. In addition, the wrought iron is beaten into thin slices, and the pig iron is tied for forging, so as to increase the contact surface of the raw wrought iron and let the charcoal penetrate more evenly. ”

Zhu Guoxiang commented: "Knowing this, it's already a great progress, don't think about becoming a big fat man in one bite." ”

Zhu Ming said with a smile: "There is also an advanced version of the steel filling method, which is the so-called Sugang." In the late Qing Dynasty and the early Republic of China, Sugang appeared in an advanced version, when the furnace temperature was more than 1,000 degrees, the pig iron melted, and the molten iron was evenly dropped on the wrought iron, and then forged. This steel filling method has better quality than Suzhou steel, and the efficiency is greatly increased. ”

Zhu Guoxiang said: "I can probably understand the principle. ”

Zhu Ming also said: "There is also a kind of retort furnace, which appeared in the Ming Dynasty and was used until the early days of New China, for casting iron tools below 1,000 catties. This kind of retort furnace is very convenient for casting small cannons. And it is very simple, it is an improved version of the Song Dynasty furnace, and you can understand how to make it when you look at the graphics. ”

"You quit your job and spend all day studying this?" Zhu Guoxiang was a little speechless.

"It's not research, it's interesting to watch, so I collect materials and make videos," Zhu Ming said, "It's more complicated, I don't understand it at all." ”

Between chatting, the father and son had already arrived at Donghua Gate.

They could enter the imperial city directly and wait in the office area of the foreign ministers, and the eunuchs had already gone to the palace to report.

There is ground tea here, and there is a honeycomb stove to boil water at any time, and the eunuch quickly brews it for them, and the tea ordering step needs to be done by himself.

Waiting for the eunuch to leave, Zhu Guoxiang ordered tea and asked, "Do you want to build a musket in Jinzhou?" ”

Zhu Ming said: "Build a few small cannons first, this thing is simpler." It is also necessary to build an iron-smelting plant and spend two or three years training skilled workers. ”

Zhu Guoxiang asked: "I know that Jinzhou is rich in gold, and there is also iron ore there?" ”

"Yes," Zhu Ming said, "I already inquired when I was in Daming Village. There are iron mines in Yangzhou, and iron mines in Jinzhou, mainly to make daily necessities, iron pots and farm tools. And there are no official mines, all of them are run by the private sector. ”

There has always been iron ore in Jinzhou (Ankang), and in 2004, even a large magnetite with reserves of more than 100 million tons was discovered.

Zhu Ming elaborated on his plan: "I went to Jinzhou, first inspected the local iron smelting situation, and then surrounded a mine to build a smelter." Groping to improve the smelting technology, it was definitely immature in the early stage, mainly building agricultural tools, and by the way, training more skilled workers. When everything is on track, build a few more small cannons, and at the same time grope for a musket. If the time is ripe, you can also build a large number of cold weapons. ”

"What if I transfer you halfway?" Zhu Guoxiang asked.

Zhu Ming said: "People can be transferred, but the smelter can't be transferred, and it is enough to arrange henchmen to continue to operate." ”

The two of them were enough, sitting in the imperial city drinking tea and discussing rebellion.

After about forty minutes, the eunuch led them to the painting courtyard.

Song Huizong did not cultivate the Tao today, nor did he play and play, but admired the paintings at the art academy.

Li Bangyan, Wang Hao, and Cai You are all there, as well as a group of painters and lyricists.

The chief painter is called Zhao Lingsui, the fifth grandson of Zhao Kuangyin, and when Song Huizong was not yet emperor, he often studied painting skills with Zhao Lingsui.

There is also a young man named Wang Ximeng, who was an apprentice at the painting academy at a young age and received personal guidance from Song Huizong. He then asked to travel all over the world, and at the age of eighteen he presented "A Thousand Miles of Rivers and Mountains", which was very fond of Song Huizong and gave this painting to Cai Jing.

As for Zhang Zeduan, he was also present at this time, but he couldn't rank at all, and he belonged to a little minion who was not appreciated.

The center of focus of the audience is Zhao Kai, the fifteen-year-old Jiawang!

"King Jia's painting art is quite the style of the official family." Zhao Lingyu patted his ass.

Li Bangyan said: "Not only painting, but also calligraphy. ”

Cai You said: "King Jia's thin gold characters already have seven points of charm in the official family. ”

The praise of many close ministers made the young man fluttering, looking at his father with expectant eyes.

Finally, Song Huizong also nodded in approval: "At a young age, it is quite good." ”

Jiawang Zhao Kai presented a painting a few days ago, and his painting art has made great progress, and Song Huizong suspected that it was not made by his son. So he came to the test, and Zhao Kai performed very well, which made the emperor feel very pleased.

Then he taught Zhao Kai's poetry and books, and his level far exceeded that of his peers.

Song Huizong liked it even more because of this, and gave birth to the idea of "this subclass me". On the contrary, the crown prince Zhao Huan and Song Huizong felt that their qualifications were mediocre, and they could not be compared with Zhao Kai, the king of Jia.

The thought of changing the prince flashed, but fortunately, Song Huizong was not mediocre to the end, and knew that this kind of thing must not be done.

But he just wanted to show off, attracted many close ministers, and asked Zhao Kai to paint on the spot, which was nothing more than the mentality of parents showing their children.

Everyone was patting on the back, although it was slapped on Zhao Kai, it made Song Huizong feel very happy.

The eunuch reported that the father and son of the Zhu family were coming, and Song Huizong immediately smiled and beckoned: "Come here!" ”

Zhu Ming went over with his father to visit.

Song Huizong scolded with a smile: "You are so good at nonsense, and within a few days of going to Puzhou, you will be impeached." ”

Zhu Ming said: "For the government and the people, do your best, and die, why are you afraid of a few impeachments?" ”

"This time I'm going back to Jinzhou, don't be willful," Song Huizong began to show off his son again, "Let's take a look at Wu'er's paintings." ”

The father and son took a closer look and found that it was really amazing, at least for a fifteen-year-old boy, this painting skill was already very superb.

After another touting, Song Huizong returned to Yanfu Palace, followed by Zhao Kai, Zhao Lingsui, Li Bangyan, Wang Hao, Cai You, and Zhu Jia's father and son.

On the way, Zhu Guoxiang took out the Rubik's Cube: "The minister made this toy with a river map and dedicated it to the official family for recreation." ”

"Hetu?" Song Huizong came to be interested.

There is a formula for the Rubik's Cube, and Zhu Guoxiang has been studying it for more than a month, summed up many rules, and then memorized them by rote.

I saw him mess up the Rubik's Cube, twist it all over again, and quickly restore it.

Song Huizong took it over to play, and twisted it a few times to disrupt it, but he couldn't recover.

The more you twist, the more anxious and upset.

Song Huizong simply stopped, the eunuch put the golden chair, and the goods sat directly on the side of the road to play the Rubik's Cube.

After playing for a long time, there were always two or three variegated colors that could not be corrected, and Song Huizong said depressedly: "You come to make a whole color, screw it slowly!" ”

"Yes." Zhu Guoxiang began to recover slowly.

Song Huizong observed for a while, took it back into his hand, and continued to play after being disrupted.

Everyone could only stand and wait, and it took nearly half an hour for Song Huizong to finally restore the Rubik's Cube. The sense of accomplishment speaks for itself, and he smiles, "It's not too difficult." ”

This thing has become addicted to playing, completely ignoring others, and continues to fight wits and courage with the Rubik's Cube there.

The second restoration, which took less time than the first, seemed to have experience in Song Huizong.

After restoring it three times in a row, the emperor finally stopped and said approvingly: "This thing is excellent, implying the way of magic, Aiqing can always make such a novelty." Can it be named? ”

Zhu Guoxiang said: "The minister is temporarily named Magic Square. ”

"That's a good name," Song Huizong nodded, "and go to a feast with me." ”

Li Bangyan really likes to play, and even asked the emperor for toys: "Official, can you lend the magic square to the minister to play." ”

"I'll play with you for a while." Song Huizong handed it over casually.

Several monarchs and ministers moved to the banquet, and Li Bangyan drank a few glasses, ignoring the emperor's presence and kept his head in tinkering with the Rubik's Cube.

Song Huizong was hooked up and scolded: "It's good to eat and drink, give me the magic square!" ”

Li Bangyan smiled and handed back the toy, turned his head to Zhu Guoxiang and said, "How did this magic square do, Mr. Zhu wants me to know." ”

Zhu Ming joked: "Twenty runs, do you want to buy it?" ”

"Buy, I'll want ten." Li Bangyan said.

Wang Hao also came to join in the fun, and he was still competing: "I'll buy twenty!" ”

Zhu Guoxiang felt that he could open a toy factory.

Song Huizong didn't let Li Bangyan play the Rubik's Cube, but he played it himself, twisted it while drinking, and said happily: "Aiqing has merit in offering the magic cube, since you like farming, you will give ten hectares of land on the outskirts of Tokyo." ”

Zhu Guoxiang arched his hand and said: "Outside the city of Tokyo, the land has already been owned. If Your Majesty wants to give land, you can give the barren mountains and land in Yangzhou, so that it will not disturb the people. ”

Song Huizong said: "I will rely on Aiqing, but ten hectares of barren mountains are too shabby, you go and choose fifty hectares of barren mountains." ”

5,000 acres of mountainous land were given casually.

It's not that Song Huizong is so mediocre, but that the emperors of the Song Dynasty are like this, and they give acres of land at every turn.

If it is fertile farmland, it is generally given 2 to 10 hectares.

If it is a wasteland mountain forest, it is often thirty or fifty hectares.

The above is given only to private individuals, but often to various institutions. For example, Song Shenzong gave Xingde Zen Monastery 30 acres of silt land at one time, 3,000 acres, which is the best cultivated land. Even people with fields, directly encircled!

Emperor Huizong of the Song Dynasty revered Taoism, and in the past two years, he has rewarded countless temple fields to Taoist temples, which has further intensified the land annexation across the country.

The territory of Daming Village is rewarded by the emperor, and it will be legal in the future.

(I drank too much yesterday, so try to make up for that one today.) ）
