The peach blossoms in the Wei River bloomed, and Mr. Wang Xiaotong from Liaodong sent an urgent message. The problem is not big, nor is it small.

The new blast furnace of Shicheng Steel Plant exploded.

A Betherman-style blast furnace blower is nothing, this is something that Zhang De has long been worried about and expects at the same time. As long as Wang Xiaotong and Wang Xue’s children are not dead, a few Khitan slave workers are nothing.

The problem is that human life cannot be filled in in vain, and it makes people think about why the blast furnace explodes.

Based on his observations over the past few years, the author of "Jiu Gua Jing" said to Zhang Dexin: "I Guan No. 3 New Furnace has been around for a long time, and the regulations of the carbohydrate-based iron material and the old Furnace No. 1 and 2 have slightly changed. Carbonite is produced by local coking, but the source of iron material is different. The old materials are the Youji Liao subway mine, and the materials transported by Dahe Guge, and there is very little fluorite. However, the No. 3 New Furnace is produced by the old iron tools in Qilu, and the mines are fluorite..."

After shaking the envelope, Lao Zhang slapped the letter paper on the table, then patted his palm, feeling a lot of emotion.

In fact, Mr. Wang Xiaotong was not funny, and he also spoke with a data table. He listed the comparison of the ore nail output rate of the local iron ore of Youji and the production in Shandong in Denglai. At the same time, the iron material sources were divided and a primary file was established.

To be honest, one thing that Lao Zhang has always admitted to his account in his two lives is: no one who plays mathematics is a fucking fame.

The sequence of admiration for engineering dogs is probably the mathematician-physicist-engineering dogs.

"Everything will change in the ages, but only mathematics will not change, and only mathematics will not deceive people."

Zhang De said to himself with some emotion, then hurried to the study room, passed by the side wing, and called out, "Sanniang, come here to help me grind ink."

"Yes, that's it."

Putting down the needle and thread in her hand, there were some clothes and cloth heads in the basket, obviously she was busy with fine work. Bai Jie was a woman with exquisite hands, unlike Zheng Wan's bold and unrestrained style. She was a typical scheming bitch who was 1,500 years later, and was very generous in the Tang Dynasty.

The only regret is that this woman was in the hands of Zhang Caozhi and she would never be able to be properly promoted in this life.

Originally, Bai Jie wanted to speak with her beauty and temperament, but she didn't know that the Liangfeng County man who was bored had sex with her, but she had a son.

It can be said that if a scheming bitch knew why Zhang De was so "indifferent", he would probably only complain that Zhang De and Zhang Caozhi were a scheming boy.

Although she has always shown herself as gentle as water, she has never seen anything she ordered.

After a moment, Bai Jie, who had laid the rice paper, saw that Zhang De was already writing quickly. She glanced at what Zhang De wrote, and then she was stunned.

She knew every word, but when she put it together, she had no idea what kind of bullshits they were.

Of course, there are still people who don’t know... but that doesn’t matter. There are not many people in the Tang Dynasty who know each other, in addition to the students of engineering dogs, there are also students of Wang Xuezi.

Mr. Wang Xiaotong knew the benefits of coking, but he didn't know why coking coal was better than wood. Lao Zhang did not talk about thermodynamics or energy with him, but introduced a concept of temperature to the old man.

Therefore, on the day when the peach blossoms in the Wei River bloomed in the ninth year of Zhenguan, the author of "Jigu Suanjing" defined the solid-liquid mixed temperature of water at a standard atmospheric pressure as zero degrees.

Then the old man thought about it and added a note: When the water boils, it will be a big deal.

As for the iron ore division inspection work, the effective ingredients in iron ore, and the color classification of iron ore, these are all details... No matter how you do it, the new blast furnace will still have to be fried several times.

Of course, after writing, Zhang De's hands were a little sore. After putting the envelope, he asked someone to send it to Shicheng Steel Factory immediately.

"Ah Lang is a little tired?"

Bai Jie blinked and looked at Zhang De with a slightly playful look. The typical scheming bitch is good at talking and all of them say love words. In short, their eyes can be seductive...

Lao Zhang originally said he was a little weak, and he had to punch in Zheng Wan for a while and deal with technical problems for Mr. Li every day.

But when he saw the third lady as warm as water, her appearance was as weak as bullying, a ball of restless fireworks suddenly appeared in her heart. She just wanted to peel the delicate lotus flowers one by one.

Zhou Dunyi said, "There is no vines or branches" and said, "You can only see from afar and not play with it." But Zhang De felt that Lao Zhou's words were unscientific. A normal young man just wanted to "play" and pat his butt and leave?

The noble style is definitely there.

The spring peaches are covered with calyx in the wind, and the young girl with a plump juice is dressed up slightly, and the fragrant hormones are given mating instructions to the male dog's brain.

Not to mention that this woman is not only full and juicy, but also a graceful lady. The silk dress has faded, and her white body is as soft as silk and satin, and she just lets the strong man place it on the desk table.

Hurry!

The evil fire came up, and there was no way to suppress it. Zhang De untied his belt and swept the pen, ink, paper and ink on the desk. Bai Jie was startled. It was probably because the weather was still chilly. Zhang De took a quick step, held the study door with both hands, and leaned his head and shouted, "I have something important to do, don't make a noise!"

Bang!

The door was closed severely, which eliminated the cool breeze in the late spring and made the warmth in the house more.

"Alang..."

Somehow, when Bai Jie saw Zhang De like a tiger or a wolf, she became even more interested, like the ignorant rabbit, who was drooling in the jackals and tigers and leopards.

That's true. Zhang De didn't think there was anything new when he was flirting with the witty Hu Ji in Pingkangfang, Ren Er and others teased him in every way.

Only Mrs. Bai, who dresses gracefully on weekdays and takes off her clothes repeatedly during bedtime, really doesn’t feel tired of playing.

"You fairy, do you think you're flirting with me? Let's see how I deal with you!"

After saying that, he took off his brocade robe and placed it on the desk. Bai Jie's snow-white body rolled in. Her whole body was like a lamb slaughtered. Her teeth were bitten lightly with red lips, her eyes were filled with tears, and she looked pitiful and wanted to cry and cry and die.

The more this happens, the more evil it makes people feel enormous.

The old man shouted, but his hands and feet were not slow, and his eyes were like swords plowing the ground, and he was back and forth on this white silk figure. This woman was also very expensive, and she decided to be a little plump and a little slim. Compared to Zheng Wan's hot and passionate spirit, her beautiful spiritual thoughts were really the right thing to be the slightest and slutty taste.

The two peach blossoms on the chest are neither big nor small. They are probably a copper coin, the size of which is a bean. Bai Shimo, who doesn't know where to reincarnate, will definitely not be like Lao Zhang. He is thinking about "lightly gathering, slowly twisting, and picking again" at this moment.

Another thing is that other people use techniques, and the Zhang family is playing verbal and verbal. Even the most aggressive Ashide Yinchu also exclaimed the joy of "the flesh-tongued flowers" in this fun.

A girl who is made of water and a man who is like charcoal and fire, and the yin and yang are in harmony. With just a sound of gasping, it is a wonderful thing.

This book is also a woman with the beauty of the god of the gods. It is beautiful and elegant, and has a wide variety of charm. But no matter how beautiful a fairy or fairy figure is, there is probably no poetic and picturesque in front of this reckless body.

"Alang...Alang loves me!"

"Love you, love you, that is, love you!"

The waist and abdomen were pushed, and the legs were raised and the shoulders were resting. The posture was like a Yugong carrying a mountain, or an old man pushing a cart. The muscles were bulging and the killing decision was unspeakable. The girl opened her mouth. The little red lips, the threaded crystal liquid was more charming than the stretching of sugar water.

Squeak squeak squeak squeak...

The desk of Li Huamu trembled slightly, and the study room suddenly swept away the tranquility. Perhaps it was because of the fact that this was a scheming man who was pressing on the white silk girl said, "If the relationship lasts for a long time, I will only look down on the slow delivery..."
