Bai Juyi looked at the artifact carefully, it was a large wooden box, three feet long and two feet wide, with a round hole on each side and a handle in the middle.

What could it be? Bai Juyi really hasn't seen it.

At this time, Xue Qing next to him coughed lightly, and immediately reminded Bai Juyi.

"This is.... Bellows it! ”

Guo Song glanced at him strangely, "Bai Xiaoshu has seen the bellows?" ”

Bai Juyi shook his head and said honestly: "Weichen saw the bellows for the first time, and I heard Xue Qing's introduction on the road just now, so I remembered it all of a sudden." ”

Guo Song admired his honesty, he patted the bellows and said: "To be precise, this is called a double-acting front and rear bellows, which was originally developed by the Ordnance Supervisor to spray fire oil, but it was found that it can also blow air, and it can greatly improve the quality of cast iron when used in smelting." ”

"But... What does it have to do with hydraulics? Bai Juyi couldn't help but ask.

"That's a good question!"

Guo Song smiled slightly: "The bellows you see is just a small bellows, if you build a large bellows and use it in a large smelting furnace, it will not work by manpower, if it is driven by water power, it will produce a force that moves back and forth, then there is no problem at all to drive the large bellows." ”

Bai Juyi had a flash of inspiration, and hurriedly said: "If it is the force that drives back and forth, then there is no problem with weaving cloth and oil extraction." ”

Guo Song nodded, "That's right, but the water flow drives the blades to be a rotating force, and how to turn it into a front and back force requires careful study by the Hydraulic Research Institute." ”

Bai Juyi hurriedly said: "But in any case, the small bellows can be vigorously promoted, so that every family has one, and it will be very labor-saving to cook at home in the future." ”

Bai Juyi is deeply involved in the lives of the people, he knows that the most painful thing about cooking at home is that the coal stove is always not lit, or it will always go out, many people use bamboo tubes to blow the fire, if there is a small bellows, it is too labor-saving to cook and boil water.

Guo Song said happily: "This idea can be realized, you write it in the newspaper, let the merchant contact Taixue, and then promote it." ”

.........

Guo Song returned to the official room and reported it, "The owner of Hongwen Pavilion has been waiting for a long time. ”

Guo Song nodded, "Xuan He came to see me!" ”

Not long after, the owner of the Hongwen Pavilion hurriedly walked into Guo Song's official room.

Gu Gu was originally Sima of Runzhou, who was second only to Han Rong as the leader of Jiangnan literature, and after Guo Song established the Hongwen Museum, Han Rong recommended him to be the owner of the museum.

Guo Song immediately named him the doctor of Zhengwupin Zhongsan, served as the doctor of Zanshan of the East Palace, and took the position of the owner of the Hongwen Pavilion.

He is about 50 years old, has big ears, and has an elegant temperament, he is very principled, but he is good at flexibility, and belongs to the kind of person who is not rigid and old-fashioned.

For example, he strictly forbade students to drink alcohol in the dormitory, and beat Du Shaokang with 30 sticks, but at the same time he announced that he could drink a little wine during the dining hall on major festivals.

"Wechen see His Highness!" Bow down and salute for the sake of the situation.

Guo Song waved his hand and smiled: "Sit down and talk!" ”

Although only Xiang Guo and scholars were qualified to sit down in the Jin Dynasty's official room, Guo Song obviously respected the situation and invited him to sit down.

"Thank you, Your Highness, for your kindness!"

Flattered by the situation, he sat down opposite Guo Song.

"Wechen asked to see him because he wanted to talk about the education of the son."

Guo Song smiled: "Let me interrupt and ask one thing." ”

"What does Your Highness want to ask?"

"Today I met Bai Juyi, the school secretary of Hongwen Pavilion, in Taixue, he went to the newspaper library to work part-time in the afternoon, and he told me that the owner agreed, I don't understand it a little, what is going on?"

Gu Guan smiled and said: "It is indeed Wei Chen's agreement to go to the newspaper for a part-time job in the afternoon, to be precise, he is going to the newspaper to work part-time on behalf of the students of the Hongwen Pavilion, and the people's livelihood column is not responsible for him alone, but by the students of the entire Hongwen Pavilion, which is negotiated between Wei Chen and the newspaper Du Chief."

For example, going to the West Market every day to collect various prices is what the students of Hongwenguan do, and Wechen feels that it is good for them to let students understand the suffering of the people. ”

Guo Song said lightly: "What about the monthly income that Bai Juyi earns from the newspaper?" Is it handed over to Hongbunkan? ”

He hesitated for a moment and said: "Your Highness, Bai Juyi's family is poor, he has to support his old mother, and he also needs a disabled brother to support, so ......."

Guo Song nodded and said, "If that's the case, I can charter him to work part-time!" ”

"Your Highness, today's Weichen came to talk about the prince, in fact, it is also related to this matter."

"Tell me!"

"Your Highness, Wechen encourages the students of Hongwenguan to get in touch with the people's suffering, and assigns investigation tasks, which has a great impact on the students, but these things have nothing to do with the prince, and he is the only one who can't participate, in the final analysis, it's still a security issue, so Wechen is like discussing with His Highness, is there any way to let the prince participate in these activities like everyone else under the condition of ensuring safety? And not in isolation. ”

Guo Song took a few steps and said: "It can also be done, but it takes a lot of manpower, and at least hundreds of people need to provide him with security protection." ”

"Your Highness, but his son is not an ordinary person, isn't it normal to pay a little price to the prince?"

Guo Song nodded and smiled: "If the hall owner has anything else to say, let's say it together!" ”

"Wechen also wants to talk about the matter of the prince listening to the political affairs hall in the afternoon, Wechen thinks that it is okay to go for a day by chance, there is no need to go every day, His Royal Highness is in his prime, and it will be many years before the prince is in charge, now he might as well let him do some unofficial things, such as Salesian, such as the literary club, and then such as the folk craftsman competition, etc., since this exercises his ability, it can also allow him to make a difference, and there is no need to think about the world's major events every day, which is not something he should consider at his age."

Guo Song was deeply touched by the suggestion of the situation, and he nodded slowly: "The hall master has a point, I will consider appropriately reducing his burden." ”

Gu Guan smiled: "I hope Your Highness will decide as soon as possible, and equipped with security protection, Wechen is going to take them to Xinfeng County tomorrow afternoon, where thousands of people who fled the plague from Xiangzhou and came to Chang'an more than ten years ago, Wechen wants the students to visit some elders, and understand what the plague is going on from their mouths, and it is best that the prince can go with him." ”

"Alright! I'll think about it and I'll arrange it as soon as possible if it's feasible! ”

"That Weichen retires!" Bow and leave for the sake of the situation.

Guo Song pondered and paced back and forth, and finally he ordered left and right: "Quickly go to the commander of the Xuan Neiwei King and the deputy commander of Zhou to see me!" ”

..........

Wang Yue and Zhou Min objected in unison, and let the prince go out again, which is not good.

Wang Yue hurriedly shook his head and said: "Your Highness, I also know that it is a good thing to let the prince go deep into the people and understand the sufferings of the people, but there is really no way to ensure safety and safety, we are on defense, and we know that many things are impossible to prevent, once something happens, it is a big deal, and we can't let the prince take this risk." ”

Zhou Min also said: "Your Highness, the Tangzhou Chamber of Commerce suddenly disappeared, it seems that they have stopped, but they think that this is the most dangerous time, and it has planted a big heel in our hands, they will definitely retaliate, at this time, we must not let the prince be placed under the dangerous wall." ”

"Do you think that at this time, the Tangzhou Chamber of Commerce will still take the risk of assassination?" Guo Song asked.

Zhou Min bowed and said: "Your Highness, this is a matter of comparing risk and gain, they really won't make another move easily, for example, Pan Xiangguo or Du Xiangguo's children are walking on the street, and the Tangzhou Chamber of Commerce will never make a move, because the risk is too great, and it's not worth taking the risk for them."

But the prince is different, the value of the prince is too high, far outweighs the risk, if there is an opportunity to assassinate the son, no matter how big the risk is worth it. ”

"General Zhou is right, please be cautious!" Wang Yue also persuaded.

Zhou Min persuaded again: "The lowly post has already sent people to the grassland to investigate the background of the Sogdian Kang Hongxin, and when the Tangzhou Sect is completely eradicated, it is not too late to arrange for the prince to go out." ”

Guo Song pondered for a moment and said, "If it's not the prince, but a person who looks like the prince, do you think the Tangzhou Chamber of Commerce will take the risk?" ”

Wang Yue and Zhou Min looked at each other, is this going to use the fake world as bait to catch big fish?

"Your Highness, I'm afraid that Pavilion Master Gu won't agree!" Wang Yue hesitated.

Guo Song waved his hand, "Gu Pavilion Master, I will go and say, I will ask you, is the plan okay?" ”

Zhou Min pondered for a long time and said: "If His Highness must do it, but His Highness must be mentally prepared, even if he catches the assassin at that time, he will not necessarily gain anything." ”

"You don't think there will be a gain?" Guo Song looked at Zhou Min.

Zhou Min nodded, "The lowly and Tangzhou Chamber of Commerce have repeatedly fought for nearly a year, the lowly has a good understanding of this organization, and is very cautious, especially after planting a big fight, he will never give us a chance again, even if he catches the assassin, that is, he is just an assassin, and the lowly is also worried that he will hurt other students, they are all children of high-ranking officials, if they know that the prince is just a stand-in, I'm afraid it will ......."

Wang Yue lightly touched Zhou Min with his foot, Zhou Min was shocked to realize that he had said too much, and quickly stopped talking, he saw King Jin standing in front of the window with his hands in his hand, without saying a word, and he couldn't help but feel a little apprehensive in his heart.

Guo Song stood in front of the window and pondered, and after a while, he said lightly: "General Zhou is right, we don't need to make a risky move, the matter of the son of the world has been canceled, since they have now strengthened all kinds of precautions, it is difficult to have loopholes, then we still go back and trace their previous whereabouts, the old Sogdian man is more eye-catching, continue to track him, I believe there will be clues." ”

"Humble duty understands!"

The two saluted and retired.

Guo Song stood in front of the window with his hands down, distraught for a while, this deeply hidden Tangzhou Chamber of Commerce was like a stinger on his back, if he didn't get rid of them, he would never be at peace.

Who are they? What exactly do they want to do? Guo Song's eyes were still dark, so he couldn't see the outline at all.
