Time travel, sell Tang poems at the beginning

St. Ann's three years.

September seventeenth.

After a month of construction, the cement road from the upper east gate of Fengyang City to Lijiazhuang has finally been completed and opened to traffic.

On this day, countless Fengyang people gathered in the open space outside the Shangdong Gate to watch the excitement. The children ran around happily on the cement road. The adults were also very curious about the cement road and touched the hard cement road with their hands. , with a shocked expression on his face.

two days ago.

Lin Feng entered the palace and informed Huangfu Gongcheng of the news that the cement road would be opened to traffic today. Huangfu Gongcheng was very happy and immediately decided to hold a lively opening ceremony and personally lead all the civil and military officials to attend.

Yesterday, Fengyang Daily carried a general report on the completion and opening of the cement road to traffic. The news that His Majesty will personally lead hundreds of civil and military officials to attend the opening ceremony also spread throughout Fengyang City.

Early this morning, the East Gate was crowded with countless people. All the people had smiles on their faces. They were talking in groups, and the scene was very lively.

"This cement is so amazing, it can't be compared to the hardness of stone. If it were used to build a house, how strong would it be!"

"Of course, but you can't buy this cement if you have money. As far as I know, the official road from Lijiazhuang to Luoding City has begun to lay cement roads. It is more than [-] miles long. , how can the cement factory have excess cement to sell out?"

"Hey! It would be great if the court could build more cement plants. In this way, we can live in houses built with cement and red bricks sooner."

"I heard that cement factories need to burn a lot of peat to produce cement. At present, other places except Lijiazhuang are not suitable for building factories. I am afraid that we ordinary people will not be able to use this cement."

"I said Lao Fang, how come you know so much about the cement factory?"

Lao Fang smiled and said, "My son works in a cement factory. Do you think I don't understand?"

"I see."

The people watching the excitement all around nodded.

At this moment, a group of Imperial Guard officers and soldiers came to the east gate. The people voluntarily moved out of the way. The heavily armed Imperial Guards began to enforce martial law, and then carriages began to drive out of the city.

The people of Fengyang City knew that the carriage of His Majesty and the civil and military officials had arrived, so they fell to their knees one after another.

The one walking in the front was naturally His Majesty's dragon chariot, followed by dozens of carriages connected end to end. They stopped on the cement road after exiting the upper east gate.

Huangfu Gongcheng and Shangguan Lingyun had just stepped off the dragon chariot, and the Fengyang people at the scene immediately saluted and paid homage, "Common people pay homage to Your Majesty! Pay homage to the Queen!"

"The people of Fengyang City will be safe soon."

"Thank you, Your Majesty!"

After Huangfu Gongcheng, Shangguan Lingyun, and all the civil and military officials stepped off the carriage, their first action was to bend down and check the cement road under their feet, and then walked towards the venue where the opening ceremony was held.

Lin Feng had the lowest official rank among the civil and military officials, so his carriage was naturally ranked last. When Lin Feng arrived at the venue, Huangfu Gongcheng and Shangguan Lingyun were already sitting on the podium, and the four people below them The princes and the civil and military officials took their seats in order of official position.

"Marquis Jiangling, Your Majesty invites you."

Not long after Lin Feng sat down in his seat, Sun He walked over to him. Huangfu had invited him, so Lin Feng naturally did not dare to neglect and immediately stood up and came to the rostrum.

"I pay my respects to Your Majesty! I pay my respects to the Queen!"

Huangfu Gongcheng nodded, "Lin Feng, you made this cement, and you led people to build this cement road. You will preside over the opening ceremony."

"Your Majesty, I'm afraid it's not appropriate for me to be a lowly official. Your Majesty should choose someone else to take charge!"

"Marquis Jiangling, what do you mean? Do you think the official position I gave you is too low?"

When Lin Feng heard this, he quickly waved his hand, "No, no, your majesty has misunderstood. What I mean is that in front of your majesty and all the gentlemen, I, a junior, are really not suitable to host."

"I tell you to take it as your own, what? Do you still want to resist?"

"I dare not, I obey the order!"

Shangguan Lingyun saw that there was something wrong with the tone of the two people's conversation, and immediately said: "Feng'er, listen to your father, don't you just say a few words, just say a few words."

"Yes, Queen Mother! I obey your orders!"

Huangfu Gongcheng smiled and said, "Queen, this kid is just lazy. If I didn't find something for him to do, he would have fallen asleep sitting on the chair below."

"No way! Your Majesty, you are exaggerating."

"Exaggeration? I'm not exaggerating at all. You don't know that every time this kid goes to court, he leans on the golden pillar behind the hall and sleeps. He thinks that I don't know. I'm just too lazy to talk to him."

"what……"

Shangguan Lingyun's mouth opened wide. She really couldn't imagine that someone dared to sleep in such a solemn place like the court hall.

"My lords, fellow citizens of Fengyang City, I am Lin Feng. Your Majesty has ordered me to preside over the opening ceremony. Next, I will give you a detailed introduction to the first road built with cement in Dayan."

"First, one of the biggest characteristics of cement roads is that they are hard. The harder the road surface, the less likely it is to be damaged and the longer its service life will be."

"Second, the cement road is made of a mixture of cement and sand. The road surface can be very smooth, and the carriage can hardly feel any bumps when walking on it."

"Third, whether it's raining or snowing, the carriage can drive normally on the cement road, and the driving speed is at least three times that of the dirt road."

"These are the three most obvious advantages of cement roads compared to dirt roads. Everyone must have seen the tiny grooves on the cement road!"

As soon as Lin Feng said this, everyone at the scene looked at him. They were also very curious about why these grooves were made on the smooth road.

Lin Feng had already expected the expressions on everyone's faces at this time. He smiled and continued: "It is very easy to slip on a road that is too smooth, especially in rainy and snowy days. These small grooves are designed to prevent the wheels from slipping."

At this moment, Xiao Jun, the Minister of Industry, suddenly stood up from his chair and said, "Marquis Jiangling, I just observed the cement road carefully and found that there are deep cracks every ten feet or so. This is also Is it intentionally designed to prevent wheel slippage?”

The Ministry of Industry is indeed the leader in Dayan's architectural community. Although Xiao Jun was a military officer, he has been the Minister of the Ministry of Industry for so many years and discovered this small design at a glance.

Lin Feng smiled and said, "Master Xiao's observation is indeed meticulous. These cracks were deliberately separated by thin wooden boards when laying the cement."

"Why do we need to separate them? Is there any special purpose of doing so?"

Lin Feng thought for a while and said loudly to the audience: "My lords, everyone must be aware of the phenomenon of thermal expansion and contraction!"

"Of course."

All civil and military officials nodded to show that they knew.

"My lords, this cement road will also expand and contract with heat and cold. If there were not these cracks, such a long cement road would be damaged due to expansion and contraction."

"So that's it. Marquis Jiangling is truly a sage of his time. He actually considered the problems of wheel slippage and thermal expansion and contraction before building the road. I admire you! I admire you!"
