Half a quarter of an hour later, Zijuan walked out of Zhang Qian's bedroom with her head slumped, her shoulders slumped, and her body pressed against the wall, like a kitten who had lost a battle.

What a failure! What a failure! Lining up the girls from ancient times to the present, Zijuan can be sure that she is the one who is the most defeated.

The tricks that Aunt Thirteen taught her by hand didn't work! No matter whether she wore heavy makeup or a plain face, she didn't succeed in attracting the slightest interest in Zhang Qian's body!

As for what Aunt Thirteen pointed out yesterday, "taking advantage of his illness and weakness to push him to bed", it didn't work. Zhang Qian, who was sick, was reluctant to let anyone approach for a long time, the reason was that he had germs on his body!

What the germ is, Zijuan doesn't know. However, she knew that Shaolangjun was not lying, and it was indeed to avoid "passing" the illness to herself, so she drove herself out of the bedroom.

This made her feel sweet, and she felt more and more "unattractive". changed to another roommate, and said that she shared the bed with Shaolangjun, I am afraid that now the children are pregnant, but she has not succeeded in tempting Zhang Qian to take the initiative to touch her body.

"It's not even as good as an iron pipe!" Thinking of the word "attractive", Zijuan couldn't help but look at the bandeau that she had specially padded four or five layers thickly, and then frustrated herself and slashed the wall with her fingers.

A smooth iron pipe made his own young man observe and play intently. And he is a good and dignified big living person, but he didn't manage to let Shao Langjun's attention last more than three breaths today!

It's really shocking, it's too much. What is so beautiful about the iron pipe, it is black and cool, and it makes no difference from top to bottom. How can it be like a living man......

Scanning her undulating body from her feet to her shoulders again, she slashed at the wall harder and harder, and her fingernails were torn into two by accident. Blood seeped out along the cracks of the cracked nails, and in an instant, it was as red as a bean.

"Zijuan, Zijuan, are you outside?" Zhang Qian's voice also came, and the pain in his fingers disappeared immediately.

"Here, Shaolang-kun!" Zijuan replied in a low voice, put his fingers in his mouth, and while sucking off the blood beads under his fingernails vigorously, he quickly returned to the bedroom, "Shaolangjun, are you looking for me?" ”

What made her want to cry in an instant was that after so much time, Zhang Qian's gaze still stopped on the iron pipe, as if staring at a Xi Shi or Zhaojun, "Have you cleaned up outside?" Pack it up, you help me call Zaiwang Maobo in, I have something to find him! ”

"Yes!" The answer was a little wilted, Zijuan turned her head, drooped her head and walked out, her cracked nails hurting like a heart.

"Recently, the income of the Liushen Workshop has been good, and the monthly salary of the future housekeeper will increase by a penny, you will inform him for me." Zhang Qian's words continued to come from behind him, and he didn't know at all that he was pitying.

"Yes!" Zijuan's voice was even more weak, and at the corners of her eyes, there were already tears quietly swirling.

"It's hard for you to help me take care of my private accounts. In the future, I will take the salary of three hangs a month, take it from the box by myself, and enter it into my account after taking it! Another command came from behind, still without much warmth. However, the tears in Zijuan's eyes disappeared in an instant.

"Really, Shaolang-kun?" Turning her head suddenly, her round eyes were watery, and her immature and delicate face was full of disbelief.

"Didn't the deed of sale already let you put it away for yourself? You are now my secretary, my personal assistant, and of course you have to get a salary? Three hangs a month, and the tube eats and wears the tube. Well done, you can also get a raise. Zhang Qian carried the iron pipe in one hand and added with a smile, "Until you don't want to do it one day!" ”

"Thank you, Shaolang-kun!" Zijuan immediately burst into flames and squatted down to give a salute. Then he turned his head and rushed out of the door at a gallop, as if Zhang Qian would regret running a little slower.

"Sure enough, it's just a lack of security!" Rushing towards her figure, Zhang Qian shook his head again and smiled.

The so-called admiration, love is difficult to oneself, and the initiative to push back is just a man's self-absorption. What Zijuan wants is just a long-term sense of security. And this long-term sense of security does not have to be by climbing into the man's bed. It's the same if you can get a high salary and control your own body and life!

"Uhhh Then he returned his gaze to the iron pipe and observed it repeatedly.

Although iron pipes cost a lot of money, they are less than one-tenth of the copper pipes. And whether it is the pressing iron plate process, or according to the Wang's secret method coil forming process, there is great room for technical improvement. Once wind and water power are also used, the construction efficiency can be increased by dozens of times.

And the new address of the Ordnance Supervisor is not far from Weishui. As long as the supply of iron ingots is sufficient, theoretically, in the spring, summer, and autumn, the craftsmen in the prison can use the waterwheel to provide power, and the iron pipes can be made in a steady stream. Both efficiency and economy are far more than open mold casting.

Iron pipes are not only used for earth heating. From the point of view of cost performance, the water intake pipe of the machine well, made of iron pipe, is more suitable than bamboo pipe. In particular, the joints of different pipe sections can be matched with simple internal and external threads and twine wires with iron pipes, which can be water-proof.

Once the water leakage problem can be solved, a simple water supply and drainage system will become possible. After coming to Datang, Zhang Qian missed the time of the 21st century the most every day, when he went to the toilet and took a bath.

Without a sewer system, even if he is a high-ranking official of the fifth grade, he only has two options if he wants to solve the reincarnation of the five grains. First, go to the dirt toilet in the corner of the yard. Second, use a wooden toilet that is specially sprinkled with plant ash to deodorize. Either way, the comfort is not comparable to that of the public toilets in later universities.

People's pursuit of a comfortable life cannot be suppressed. Zhang Qian believes that once he launches the three artifacts of earth heating, running water and flushing toilets, the wealthy families in the Gyeonggi area will definitely flock to it. In that case, in the next few years or even decades, the demand for iron pipes of different diameters in the Tang Dynasty will be astronomical.

Previously, because people were soft-spoken, he had to transfer the windmill machine well manufacturing business that could make money to the general as a supervisor. This time, the young eunuch of the ordnance supervisor was surnamed Zhang, and the main superintendent said to Zhang, the squire of the military department who trusted him, that he would definitely keep this hen that could lay golden eggs for the ordnance superintendent!

The Ordnance Supervision now has three departments: gunpowder, armor staff, and bow and crossbow, and the products of any department are directly supplied to the Tang military. Therefore, it is not suitable for the iron pipe to be made and placed under the department. Even if it does not affect the normal operation of the three agencies, it will leave a handle for those officials who are picky in the eggs.

When participating in the pursuit of the dynasty, Zhang Qian profoundly understood the shamelessness and boredom of some officials. Therefore, he had to open a new agency to take charge of the manufacture of iron pipes. Just like in the 21st century, some government departments will also open some tertiary industries below, which are responsible for making money for the entire department. The nature of this institution, the future, is the same.

Professional things have to be done by professional people, and Wang Maobo is undoubtedly a suitable choice. First of all, this person knows how to repay his kindness, and his quality is not bad. Second, this person has no roots in the ordnance prison, and is easy to command. The third is that Zhang Qian had a flash of inspiration in his mind just now.

That Wang Maobo, if he didn't know how to roll iron pipes before, how could he have come up with a whole set of production processes in one day? Obviously, this set of craftsmanship was not configured by himself, but from a certain inheritance system.

Perhaps, as Wang Maobo himself said, his ancestors were not actually Goguryeo, but from the Southern Dynasties, and when the Sui destroyed Nanchen, his ancestors fled to Goguryeo. In this way, at least when the soldiers and horses of the Great Sui crossed the Yangtze River in the south, that is, around 588 AD, the blacksmiths of Nanchen already knew how to use thick iron sheets to roll seamed iron pipes.

Why is it that in the Jinglong period more than a hundred years later, no one in the Tang Dynasty military weapons and skilled craftsmen who will be the two supervisors will know this technology? The reason is also very simple, first, when the Great Sui destroyed the southern countries, many of the skills that were spread in the south of the Yangtze River were wiped out along with the flesh of craftsmen. Second, in order to prevent the apprentices from starving to death after teaching the apprentices, the craftsmen easily refused to spread the technology to the outside world.

The former factor, with Zhang Qian's current ability, has not been able to make it disappear. However, the problem of craftsmen cherishing themselves has long been a problem in the 21st century.

"Owner, are you looking for me?" At the door of the main hall, Wang Maobo's voice suddenly came again, with a little caution and apprehension.

"Well, come in, I have something to discuss with you!" Zhang Qian stepped forward with an iron pipe in his hand, and nodded with a smile, "This kind of iron pipe is extremely versatile, and it will definitely need to be built in hundreds or thousands in the future." The secret recipe is handed down from your ancestors, and Zhang can't take it for nothing......"

"What are these words, owner? Sensei said that he once owed you a great favor. I don't owe you anything, you don't have to take it to heart if it's just a recipe for striking iron! The stone in Wang Maobo's heart fell to the ground instantly, and he hurriedly waved his hand with a smile on his face, "You can use it, you can use it, it is an honor to be able to do something for you." Some time ago, because I was bedridden, I was afraid of giving the house my illness to the owner, so I didn't dare to take the initiative to come to work, and now the illness has been cured, and the owner appreciates it......"

"Listen to me first!" I really couldn't stand Wang Maobo's servile appearance, Zhang Qian frowned and interrupted, "I'm not fighting myself, but I'm going to pull a group of craftsmen out of the ordnance prison alone, and I'm responsible for building iron pipes." This group of people, I need someone to take them with me, and it just so happens that your body is no longer patient, so I thought of you. ”

"Zhuang master, you, you mean, you want to recruit me to the ordnance prison?" Although Zhang Qian emphasized that he was not allowed to interrupt, Wang Maobo still couldn't control his mouth, stared at a pair of eyes full of surprise, and muttered questions.

"Yes, I want you to make a record and take care of this for me." Zhang Qian thought about it and nodded with a smile. "Rank, currently a foreign official, fifth class! I wronged you a little. But the salary is not lower than that of working as a teacher here. And for every pipe you build, you get a penny ......."

"Poof!" The person in front of him suddenly became half a cut shorter. The sound of knees hitting the floor immediately followed and reached his ears.

Zhang Qian's words were interrupted again, lowered his head, and looked at Wang Maobo in a daze, a little puzzled why the other party had such a big reaction. But I saw that the latter was bowing down to him with tears streaming down his face.

"Engong, Wang, Wang never dreamed that there would be a chance to recover his official body in this life! Wang, every time Wang dreams of his father, he is so ashamed that he can't sleep peacefully all night. "While crying, Wang Maobo kowtowed, and every time he struck, he was extremely pious." Da En didn't dare to say thank you, in the wind and fire in the future, what Engong pointed to with a horse whip, Wang Maobo would never frown! ”
