Siheyuan: First-class Merit at the Start

On the other side, Li Polu stayed in a steel mill for four or five days, watching the tall buildings rise from the flat ground. After observing and guiding the steelmaking several times, Wang He finally let Li Polu go back with satisfaction.

Compared with the open-hearth steelmaking method commonly used in this era, the top and bottom blowing steelmaking furnace has greatly improved the stirring capacity of the molten pool due to its unique design.

At the same time, because the combined blowing process can reduce the oxygen content in the molten steel and the TFe content in the slag, it improves the dephosphorization and desulfurization efficiency and reduces the consumption of ferroalloys. This also makes the reaction in the furnace closer to a balanced state.

Then because he combined the advantages of top blowing and bottom blowing, the blowing process became more stable, reducing splashing and improving the controllability of blowing.

Coupled with better molten pool stirring capacity and metallurgical reaction conditions, this furnace can also meet the requirements for refining high-carbon steel.

Of course, in terms of effect, it is definitely not as good as the electric arc furnace and the converter, but the top and bottom furnace is better in its efficiency.

In this era of extreme shortage of high-carbon steel, this is an enormous advantage.

This can also be seen from the burning eyes of several steel workers.

Looking at the steel workers at Yigang, who looked as if they were looking at his own wives, Li Polu felt a chill.

When he arrived outside the factory, Li Bolu saw Wang He's car parked at the door waiting.

Then, he sat on it without saying a word and told the driver to drive away.

The driver naturally knew Li Polu. After hearing Li Polu's request, he hesitated for a moment, but decided not to move.

After all, he was Director Wang's driver, not Li Polu's driver. Even though he knew that Li Polu and Director Wang had a close relationship, it was too outrageous for him to run away with him just because of that.

Fortunately, Chen Jun also ran out at this time. He said a few words to the driver and chatted with Li Polu for a while before slowly starting to leave.

As for why Li Polu had to take a ride and run away, it was because Yigang was too far from Nanluoguxiang where he lived.

Li Polu was still very satisfied with Wang He's approach. At least Wang He was still a good comrade who was wholeheartedly loyal to him.

He is not the kind of person who will defeat the enemy at every turn when he is needed, and becomes Section Chief Li when he is not needed.

As soon as I stepped out of the courtyard, the system sent a prompt.

[Host changes the world timeline (industrial process - top and bottom double blowing steelmaking furnace). World line magic modification rating: A grade, magic modification score: 270 points. Obtained a level 5 treasure chest. ]

[Current points: 1504 points, can participate in the second-level lottery 75 times. 30/40.]

Looking at the points that had reached more than a thousand, Li Bolu thought it was time to draw the lottery again, so he raised the lottery level.

Along the way, the scenery of the city kept flashing past the car window. For a moment, Li Polu seemed to see a familiar figure sneaking into a small alley.

Li Bolu immediately asked the driver to stop the car.

"Master, you go back first. I'll go for a walk alone."

Li Polu stood on the street and quickly followed the familiar figure and turned into an alley. Soon, he saw the figure at the corner ahead.

It’s a great joke, that’s for sure.

But this place is Zhengyangmen. Why would a kid like Banggeng run so far?

Driven by curiosity, Li Polu hid in the shadow of the wall and carefully followed Banggeng along the way.

But after following him for a while, he felt that he seemed to be worrying too much. Because Banggeng had been sneaking into the alleyway at the beginning, except for being a little sneaky, he had no intention of looking behind him when he entered the alley.

However, the more Li Polu looked, the more he felt that the surrounding environment looked familiar.

At this moment, Li Bolu suddenly remembered something that he had long forgotten.

That was the night after he and Chen Xi spent the night at Chen's house for the first time. He was worried that Wang He, who went to Chen's house alone for the banquet, would be beaten by the hot-tempered Chen Qiu, so he chose to follow on foot.

Then he discovered that someone sneaked into an empty yard nearby at night and climbed over the wall to get in.

But later he was caught by Wang He and put in solitary confinement in the Industrial Department to do design, and the matter has been shelved since then.

While thinking about it, Li Polu saw Banggeng knocking on the door of a courtyard several times in a very regular manner. Then, not long after, a middle-aged man with the same inverted triangle eyes as Jia Zhangshi came to open the door for him.

Seeing that only Bang Geng was there, he let him in. At the same time, when closing the door, he looked around vigilantly, and then carefully closed the door.

What a coincidence that this courtyard was right next to the courtyard that Li Polu had remembered that night.

This made Li Polu even more curious. Could it be that Banggeng was not only a thief, but his character had also changed?

Without any hesitation, Li Bolu decided to find out what was going on.

He released a nanorobot that synchronized with his vision. After crossing the high wall and thick gate, Li Polu's young mind was once again hurt as much as the critical hit he received in Sha Zhu's cellar when he went to the black market in the middle of the night.

I saw that in the huge main room, all the things in the room had been moved out, and there was a stove for heating in each of the four corners of the room.

The floor of the room was covered with bedding and cotton-padded clothes were scattered all over the floor.

There were about 30 men and women of different ages in the room. The oldest one was probably an old man who looked to be about 80 years old, but he didn't have any teeth.

The youngest is probably Banggeng, who is only seven or eight years old now.

Seeing this scene, Li Polu's mouth twitched. The scene was so exciting.

Li Polu couldn't help but sigh in his heart that Banggeng already had the qualities of a great emperor at such a young age, and his future achievements would surely be limitless.

In other words, he was born at the wrong time. If he had been reborn in Japan in the 21st century, he would have become a superstar and contributed to the GDP of that country.

At the same time, he couldn't help but think of an organization that should have appeared a few years later.

But on second thought, it didn't seem right. He had just retired from there, so where in the country would a Komodo husband come from to promote this thing?

However, as a model young man, Li Bolu naturally chose to report such things.

But before that, he decided to explore the yard next door first.

Then, he controlled the nanorobot to fly to Hebi's yard. He turned and left the alley, heading towards the nearby police station.

"Comrade security officer, I want to report a crime."

Li Polu naturally could not give a detailed explanation of the content of the report, he only said that he had a friend living nearby and heard some strange noises coming from the yard when he passed by.

He stood there and listened for a while, and then he heard a lot of voices, thinking that he must have encountered a human trafficker's den. He didn't dare to delay and ran to report the case.

As for the matter of the courtyard, Li Polu did not say anything, because the robot had just gone in and looked around, and there was no sign of anything being moved recently. But the secret room was filled with large and small yellow croakers and some antique calligraphy and paintings.

Li Polu had no shortage of these things, but since he had come across them, there was no reason for him to let them go. So he naturally refused them.

When the security guard heard that they were suspected of encountering human traffickers, he did not dare to delay. He immediately called a group of people and followed Li Polu to the courtyard that Li Polu mentioned.

However, after the security guards listened outside the wall for a while, they felt that the matter was not that simple.

There were indeed people screaming in the yard, but the sound didn't sound right. And there seemed to be quite a lot of people.
