Outside the sour jujube gate in the north of Kaifeng City, Cao Guangzhi glanced at Wang Zhongyong, who was sorting out the soldiers not far away, and whispered to Yin Yue beside him: "Envoy, why did you let this reckless man bring soldiers with us?" Along the way, with him by our side, aren't we inconvenienced? ”

Yin Yue lowered his voice and said: "The master doesn't know, Hedong Road has always been very guarded against us outsiders, although we have post tickets on us, if there are no officers and soldiers accompanying us, it will still be difficult to travel on this road." Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info With Wang Tihar by his side, he saved a lot of tongue. As long as we are careful on the road, we will be fine. ”

Seeing Cao Guangzhi's disapproving look, Yin Yue said again: "Two days ago, I listened to the new words of Yongning Hou, I thought about it again and again, and asked people to inquire everywhere, and they all said that Yongning Hou had an unsatisfactory life in the capital this year, and it seemed that he had the intention of making contributions to the frontier again. Where is the matter in the Great Song Frontier now? It's not a state army that borders our party. This news is no less than investigating the geography of Hedong Road. We are cautious along the way, as long as there is no chaos and a rough survey of the road on Hedong Road, it is enough to go back to our lives. ”

Yin Yue is the right envoy, since he said so, what else can Cao Guangzhi say?

On the other side, Wang Zhongyong was even more complaining. When I played, I had already said that Hedong Road was a heavy road along the border, and Wutai Mountain was in Daizhou, the most border, and it was inconvenient for the envoy to do things, but I didn't expect the political hall and the Privy Council to agree. It's okay to agree, and let him lead the soldiers to escort him along the road, it's really a hell of a life!

The so-called escort along the road, the government hall and the Privy Council mean that the most important thing is to protect and monitor, so as not to let them do things that endanger the imperial court. But on the surface, Wang Zhongyong's duty is to protect the party envoys. The orders from above and below did not say which one was heavy and which was light, and the weight in the middle depended on Wang Zhongyong himself.

How does Wang Zhongyong handle it himself? The envoy was not satisfied, and the board hit himself first, and it is great to maintain the current harmonious relations between the two countries, and there is no need to have any doubts. But what if the party envoy does something out of the ordinary? No one told Wang Zhongyong. If he is allowed to do so, he will still not be able to run away when the two countries fight each other, and he will be held accountable at that time.

It's a bastard errand!

In Xu Ping's back garden, a pergola was built in the shade of a few big trees, and a table was set up in it, and there were melons, fruits, tea, and various fruit cakes on the table.

In the open space on one side, Li Shengrong and Sun Qilang were bringing a few craftsmen to make the parts needed for the carving pendulum, while on the other side, Yan Su was directing people to make the shells and shelves for the carving pendulums.

Under the big tree, Pan Pan and Su Song, Wei Pu, and Chu Yan were playing shuttlecocks. Wei Pu's glasses have been matched, and everything he sees after wearing them is very novel, and he doesn't refuse what others tell him to do, so he runs over happily.

Leaning against the pond, Xiuxiu sat on a small chair against the big tree to do needlework, looking at Panpan from time to time, for fear that she would do something strange.

Xu Ping originally didn't allow Panpan to come back to the back garden, they were doing their right thing, how could they be distracted to watch the children again? didn't want to look forward to the thief and thief, Xiuxiu couldn't watch it, and couldn't control her, so she still slipped in.

Xu Ping had no choice but to make an appointment with Panpan for three chapters. Don't disturb everyone to do business, and you can only play with her when you are resting. When no one passes, be honest and don't make any tricks.

Panpan is making trouble, he has always known how to be measured, far from the point of being unreasonable, and obediently abides by Xu Ping's rules.

Li Shengrong held a file and fine sandpaper in his hand, his expression was meticulous, and he was unhurriedly polishing the steel parts in his hands.

Sun Qilang was on the side, he couldn't do this kind of delicate work, so he could only come up with ideas and hand over tools.

It is Xu Ping's requirement to make a steel mold first, and then use the steel mold to extrude brass parts, and then refine. If you use brass directly to make the relevant parts, it is too time-consuming and labor-intensive. The most important thing is that if you use brass parts directly, each part is different, cannot be universal, cannot be interchangeable, and will be quite troublesome in the future.

Although the time to make the steel mold will be longer, once it is made, it can be produced in batches, and small parts can be replaced at any time if they are broken, which saves time in general. Most importantly, if you really want to produce carved pendulums in large quantities in the future, these steel molds will be of great use and can be quickly mass-produced.

At the beginning, the engraved pendulum volume is very large, and the corresponding parts do not need to be so fine, and the most important thing is to adjust the size of the pendulum, which is well matched with the corresponding gear train speed ratio. There are 12 hours in a day, but how long these 12 hours are is a delicate technical problem, and it takes a lot of manpower, material resources and time to measure. Xu Ping naturally couldn't wait for adults to accumulate data over the years, so he had to borrow Si Tianjian's existing data and slowly adjust it later. How to make the cycle of the pendulum into a suitable ratio with these twelve hours, not only to make the gear train speed range as small as possible, but also to make the pendulum can be adjusted more conveniently, and this adjustment is as precise as possible, it is necessary to work hard from calculation, design and manufacturing.

The requirements of the escapement are also much higher than those of the previous guide car and armillary sphere, requiring the gear train to swing and move, and to eliminate the gear meshing gap as much as possible, all of which require exquisite design and exquisite manufacturing.

A pendulum clock looks thick and bulky, and the principle is not complicated, but there are still many details to be taken care of in order to make it more accurate than its predecessors.

Yansu made the lotus drain, it took decades, and the accuracy actually surpassed many shoddy pendulum clocks in Xu Ping's previous life. It is not easy to surpass the accuracy of the lotus drain.

Seeing that Li Shengrong was busy sweating profusely, Xu Ping said: "Let's take a break, come over for a cup of tea, and eat some melons and fruits." It's a delicate job, and you can't be sloppy or rushed. You must be calm and spend time grinding little by little. ”

Li Shengrong straightened up, wiped a handful of sweat, and sat down at the table. Sun Qilang looked obedient and hurriedly followed over and poured tea.

Assembling and disassembling is what Sun Qilang is good at, and he is far from making these fine utensils when he calms down, and he has been by Li Shengrong's side for the past few days, which is really eye-opening and learning. People who really do things by themselves are respectful to those who do have the ability from the heart, but those who never do it like to point out the country, and they can't look down on any of them.

Xu Ping asked Li Shengrong some small technical questions, and used his experience in his previous life to give him reference advice.

In his previous life, Xu Ping was no stranger to specific production techniques, but he saw more and did not do it himself. If you don't touch many things yourself, you won't be able to grasp the most critical point. Looking at it from the side, you said that changing this square to a circle would solve everything, but in fact, changing it to a circle may require countless efforts and cannot be completed at all.

Not everyone is a genius and will have their own limitations, and Xu Ping is self-aware of this.

After drinking two cups of tea and eating a few pieces of watermelon, the sweat on his body disappeared, and Li Shengrong got up to prepare to start work.

At this moment, a subordinate hurriedly came in from outside and saluted Xu Parallel: "Marquis, there is a Liu Qiguan outside, asking to see him." Now that people are in the living room, I don't know if the marquis sees it or not. ”

After speaking, he handed over the prayer note in his hand.

Xu Ping took the post and unfolded it. After thinking for a while, he said to his subordinates: "You go and tell Liu Qi that I am a little inconvenient here, so I won't see him." By the way, tell him that he just needs to take office with peace of mind, work hard, and don't make any more mistakes. ”

The servant agreed, turned around, and went.

The new song "Breaking the Array" was sung in the capital for a while, first, everyone listened to it freshly, after all, this song was very different from the previous ones. Another Xu Ping's meritorious achievements in Yongzhou are a major event in the imperial court in recent years, whether it is official or civilian, everyone has a lively time, and there is a topic to talk about when they get together.

all know that it is a new song that Liu San has painstakingly made into Xu Ping's lyrics, and the meaning is self-evident. Xu Ping is also an upstart in the imperial court, and when the Court of Judges arranged for Liu San to change his new position, he could not help but consider this.

Two days ago, Di Di from the Magistrate's Court visited Xu's Mansion, and Xu Ping mentioned it casually, and Di Di understood it. After going back, Liu Sanbian escaped a catastrophe and did not go down to the first rank to serve as the official of the state, but changed to Hedong Road to Renzhi County.

Since that day, Xu Ping held a meeting to eat watermelon, and officials have come to Xu Ping's mansion almost every day. If you come, you will have watermelons to eat, and if you don't come to buy them, there is nowhere to buy them, Xu Ping has that identity and status so capricious.

Whether it is for greed, or for the sake of friendship with Xu Ping, an upstart, in short, there is this excuse, and Xu Ping's family has constant guests. Xu Ping naturally doesn't have that idle work, everyone sees it, there is always a choice, otherwise there is no need to do anything else all day long. Di Di came to see what a watermelon looks like when it grows in the ground and what it tastes like when it is eaten in his mouth, but he actually came to listen to Xu Ping's attitude towards Liu Sanchang. Convinced from Xu Ping, Liu Sanchang's new official notice was quickly issued.

And Liu San's change of level, except for special reasons, Xu Ping will never see it. Moreover, today it is clear that Liu Sanbian is going to Hedong Road to take office and come to Xu Mansion to thank him, what is Xu Ping doing when he sees him?

The help has already helped him, and when you see him, you have to remember your kindness, and if you don't see him, you have to remember your kindness, so why waste time? spread out, others may still say that Xu Ping is seeking wealth with grace, which is not good for his reputation.

However, the most diligent ones were the group of pavilion officials led by Ouyang Xiu. They didn't come to slap Xu Ping, most of these people were arrogant and arrogant, and people with status had to slap them in turn.

These pavilion officials took a fancy to the vast area here in Xu Ping, and there was food and drink in Xu's mansion, and if they drank too much, they couldn't go back and had a place to sleep. Every once in a while, groups come to Xuping's mansion to gather, regard this place as a scenic spot, enjoy the scenery and play the party. Xu Ping doesn't care if he sees it or not, he just wants to be happy.

Knowing that Xu Ping organized a carving leak society to make a new carving leak, these people also came to watch the excitement a few times, and wrote a lot of poems. Among these people, there are those who study astronomy, and there are those who are interested in the carving of bells and drums, but no one squats here every day when it comes to the technical problems of real and specific details.

The days when officials serve in the pavilion are not only the most relaxed and comfortable time, but also the time to learn knowledge and enrich themselves. Chongwen Academy has the richest collection of books in the world, all-encompassing, and is surrounded by well-educated people, as long as you have the heart, you can learn a lot of things. Moreover, the status of the pavilion bachelor is transcendent and noble, the government can be blamed, and the minister often sees that there are countless things to do, how can he spend his mind on such a thing?
