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

Too failed! Too failed! Too failed! Zijuan can be sure that she is the most failed girl from ancient times to the present.

All the tricks that Aunt Thirteen taught me step by step were useless! Whether it was heavy makeup or plain face, she failed to attract Zhang Qian's interest in her body!

As for what Aunt Thirteen gave yesterday, "pushing him to the bed while he is sick and weak", it doesn't work. Zhang Qian, who is sick, is unwilling to let anyone get close for a long time, because he is actually carrying bacteria on his body!

Zijuan didn't know what the germs were. However, she knew that the young man did not lie, and it was indeed to avoid "passing" the disease on her and she drove herself out of the bedroom.

This made her feel sweeter and she felt more and more "unattractive". If she had changed to other girls who were in the same bed with the young man, she might be pregnant now, but she has not been able to tempt Zhang Qian to take the initiative to touch her body.

"I'm not even as good as an iron pipe!" Thinking of the three words "attractive", Zijuan couldn't help but look at the place where she had specially padded four or five layers, and then was frustrated and tapping the wall with her fingers.

A bare iron pipe made my young man observe and play with her eyes. And my very own living person failed to attract the young man's attention today, and it lasted for more than three breaths!

It's really a blow to people, too much. What's the best thing about iron pipes? They're black and cool, and there's no difference from top to bottom. It's not like a living person...

From her feet to her shoulders, she looked at her body without any ups and downs again. She tried harder to pick the wall. If she accidentally broke her nails into two pieces. The blood oozed out through the cracked nail gap, and in an instant, it was as red as beans.

"Zijuan, Zijuan, are you outside?" Zhang Qian's voice came, immediately causing the pain in his fingers to disappear.

"Here, Young Master!" Zijuan replied in a low voice, put his fingers into his mouth, and while sucking off the blood beads under his fingernails, he quickly returned to the bedroom, "Young Master, are you looking for me?"

What made her cry in an instant was that for so long, Zhang Qian's eyes were still on the iron pipe, as if he was staring at a Xi Shi or Zhaojun, "Have you cleaned it outside? After packing it up, please help me call Wang Mao Bo in, I have something to look for him!"

"Yes!" The answer was a little wilted. Zijuan turned her head and walked out with her head hanging down. The cracked nails hurt like a heart-wrenching pain.

"The Liushen Workshop has made good returns recently. From now on, the monthly salary of the housekeeper will increase by a little money. Please inform him for me." Zhang Qian's words continued to come from behind, without any idea of ​​pity for the fragrance and savor.

"Yes!" Zijuan's answer was even more weak, and tears were already vaguely spinning in the corners of her eyes.

"It's been hard for you to help me manage my private accounts. From now on, I will get three hang of money every month, and I will take it from the box and make it my own account after I take it!" Another order came from behind, but it still didn't contain much warmth. However, the tears in Zijuan's eyes disappeared in an instant.

"Really, Young Master?" She suddenly turned her head, and her watery eyes were wide open, and her tender and beautiful face was full of disbelief.

"Didn't you let you put away the contract yourself? You are my secret now and my personal assistant. Of course you have to get a salary? Three hangers a month, food, clothing and housing. If you do well, you can also get a salary increase." Zhang Qian held the iron pipe in one hand and added with a smile, "Until you don't want to do it one day!"

"Thank you, Young Master!" Zijuan immediately became excited and squatted to salute. Then she turned her head and rushed out of the door like lightning, as if she was running a little slower, and Zhang Qian would regret it.

"It's true that it's just a lack of security!" Zhang Qian shook his head and smiled again as he jumped away at her.

The so-called love, love is hard to control, and taking the initiative to reverse it is just a man's self-intoxication. What Zijuan wants should be just a long-term sense of security. But this long-term sense of security does not necessarily require climbing into the male owner's bed. Being able to get a high salary and being able to control your own body and life by yourself is the same!

"Woo--" With the satisfaction of using reason to penetrate the fog on the surface, he whistled softly. Then he fell back to the iron pipe and observed repeatedly.

Although iron pipes are expensive, they are less than one-tenth of that of copper pipes. And whether it is the pressing iron plate process or the rolling tube forming process according to Wang's secret method, there is great room for technological improvement. Once wind and hydraulic power are used, the construction efficiency can be improved dozens of times.

The new address of the military weapon supervisor is not far from the Wei River. As long as the iron ingots are supplied sufficiently, in theory, in spring, summer and autumn, water trucks are used to provide power, the craftsmen in the supervisor can continuously manufacture iron pipes. Both efficiency and economy are far beyond mold casting.

The purpose of iron pipes is not only earth heating. From the perspective of cost-effectiveness, the water drainage pipes of the machine well are more suitable than bamboo pipes. Especially for the connection parts of different pipe sections, the iron pipes are matched with simple internal and external threads and twine, so that water is not leaked.

Once the water leakage problem can be solved, a simple water supply and drainage system will become possible. After coming to the Tang Dynasty, Zhang Qian missed the 21st century most every day, when he was on the toilet and taking a bath.

Without a drainage system, even if he became a fifth-rank high-ranking official, he had only two choices to solve the cycle of grain reincarnation. First, go to the earthen toilet in the corner of the yard. Second, go to the wooden toilet that is specially sprinkled with wood ash to deodorize. No matter which choice, the comfort is incomparable to the public toilets in later universities.

People's pursuit of a comfortable life is uncontrollable. Zhang Qian believes that once he launches three magical tools such as earth heating, tap water and flush toilet, wealthy families in the capital will definitely flock to it. In that case, in the next few years or even decades, the demand for iron pipes of different diameters among the Tang Dynasty will be an astronomical figure.

Previously, because of his slightest words, he had to hand over the windmill well manufacturing business that could make money to the general manager. This time, the young supervisor of the military weapon supervisor was named Zhang, and the chief supervisor was Zhang, who trusted him, and said that he would definitely keep this hen that could lay golden eggs for the military weapon supervisor!

Military weapons supervision now has three departments: gunpowder, armored staff, and crossbow. No matter which department's products are directly supplied to the Tang army. Therefore, it is not appropriate to manufacture iron pipes under which department is placed. Even if it does not affect the normal operation of the three departments, it will leave a handle for those censors who are picking their bones in the eggs.

When he participated in the pursuit of the court, Zhang Qian deeply experienced the shamelessness and boredom of some censors. Therefore, when creating iron pipes, he had to open a separate new organization to be responsible for it. Just like in the 21st century, some government departments would also open some tertiary industries to make money for the entire department. The nature of this organization will be the same in the future.

Professional things must be left to professionals, and Wang Maobo is undoubtedly a suitable choice. First of all, this person is grateful and has good quality. Second, this person has no roots in the military weapon prison and is easy to command. Third, Zhang Qian's mind just now is suddenly inspiring.

Wang Mao Bo, if he hadn't known how to roll iron pipes before, how could he have produced a whole production process in one day? It's obvious that this process was not figured out by himself, but from a certain inheritance system.

Perhaps as Wang Maobo himself said, his ancestors were not Goguryeo, but from the Southern Dynasty. When the Sui Dynasty destroyed the Southern Chen Dynasty, his ancestors fled to Goguryeo. In this way, at least when the soldiers of the Sui Dynasty crossed the Yangtze River south, around 588 AD, the blacksmiths of the Southern Chen already knew how to use thick iron sheets to roll the sewn iron pipes.

Why did the Tang army weapons in the Jinglong period more than a hundred years later, no one knew this technology? The reason was simple. First, when the Sui Dynasty destroyed the southern countries, many of the skills circulated in Jiangnan and the bodies of craftsmen were eliminated. Second, in order to avoid starving the master to death after teaching his disciples, the craftsmen easily refused to spread the technology to the outside world.

The former factor, with Zhang Qian's current ability, cannot be made to disappear. However, the problem of craftsmen cherishing themselves has long been no longer a problem in the 21st century.

"Master, are you looking for me?" At the door of the main hall, Wang Mao Bo's voice suddenly came, with a little caution and uneasiness.

"Well, come in, I'll discuss with you if you have something to do!" Zhang Qianshen came forward with an iron pipe and smiled and nodded, "This kind of iron pipe is of great use and will definitely need hundreds or thousands of pieces to make in the future. The secret recipe is passed down from your ancestors, and Zhang cannot take it for nothing..."

"What are you saying about the owner of the manor? Don't say that I once owe you great kindness. I just don't owe you. You don't have to take it seriously!" The stone in Wang Maobo's heart fell to the ground instantly, and he waved his hand with a smile on his face, "You can use it, and use it. It is a privilege to do something for you. Some time ago, because I couldn't afford to get sick, I was afraid of giving it to the owner of the manor, so I didn't dare to come and take the initiative to come and apply for it. Now the manor's illness has been cured and I am appreciated by the owner..."

"Listen to me first!" I really couldn't stand Wang Mao Bo's servile appearance, and Zhang Qian interrupted with a frown, "I'm not fighting myself, but I'm going to pull out a group of craftsmen in the military weapon prison to be responsible for building iron pipes. I need someone to take them with me. It just so happened that your body was no longer in vain, so I thought of you."

"Master, you mean, do you want to recruit me to the military weapon surveillance?" Although Zhang Qian emphasized that it was not allowed to interrupt, Wang Maobo still could not control his mouth. He stared at his surprised eyes and murmured to ask.

"Yes, I hope you do a record and specialize in this matter for me." Zhang Qian thought about it and nodded with a smile. "Are you a foreign official at the moment, the fifth grade! I feel a little wronged. But the salary is no lower than being a coach here. And every time you build a pipe, you can still get a penny..."

"Puu!" The person in front of him suddenly became half short. The sound of his knees colliding with the floor followed by the sound of his ears.

Zhang Qian's speech was interrupted again, lowered his head and looked at Wang Mao Bo blankly, a little confused about why the other party had such a big reaction. But he saw that the latter was bowing to him with tears in his face.
Chapter completed!
