The production of steam engines requires the design of cylinders, pistons, flywheels, governors, valves, etc. The most important thing is the boiler, and it is not possible to do without it.

With the temperature sensing and pressure control array, the only difficulty in designing the boiler for Jiang Xingchen is nothing more than casting and material problems.

But after drawing a rough outline drawing based on the impression in his mind, Jiang Xingchen stopped. He thought of a serious problem, which was environmental pollution.

Xingchen leads the mountains and rivers to be green, and it is the tourism industry, and if a large amount of charcoal and firewood are burned, it will definitely have an impact on the environment...... Of course, if it's just a steam engine, it's okay to burn it, but once this thing develops, it is estimated that it can't be stopped if you want to, and the effect is too great.

If others don't say it, Xian Ning will ask for an increase in scale. I have mentioned to her about the machine tool before, and she has also said that she will use a windmill or water drain to design the machine tool as the driving force, which will drive the development of the foundry industry to speed up, such as the blacksmith workshop to make steel pipes can use cold drilling technology, without pouring with a steel core and then quenching and welding in a section.

However, if the steam engine were to be mass-produced and mass-produced, it would be an absolute disaster for the environment, and the pollution process after the industrial revolution in Europe in the last century is terrifying to think about. He didn't want to ruin such a good environment as Star Leader.

After thinking quietly for a while, Jiang Xingchen picked up the pen again, if there is no machine tool and no corresponding power source, how can rubber be refined. In the future, the large quantities of materials needed for construction will not be produced. In terms of transportation alone, the convenience obtained is greater.

He was struggling with the work here, and the door opened, and Mei'er walked in.

"Brother. Why did you just come back and work, and I was busy for so many days. Don't say two days off!" Mei'er walked up with some distress and removed the pen from his hand.

"No matter how important the work is, you have to pay attention to your body! Don't write!" Mei'er dragged Jiang Xingchen away from the table forcefully.

Jiang Xingchen stood up obediently. The entanglement just now was temporarily put down, and he hugged the little girl into his arms with tenderness. This girl has become quieter and quieter as she gets older, and she has become more and more considerate of herself, and this kind of tough appearance has not appeared for a long time.

For some reason, Jiang Xingchen was not disgusted with the little girl's self-care, but enjoyed it very much. This made him feel that he and the little girl really formed a family.

"Mei'er, have you thought about it? It's time for our wedding!I have to write a lot of invitations, I can't invite anyone!" Jiang Xingchen sat on the edge of the bed with Mei'er in his arms, and his right hand easily penetrated into the gap in the clothes on the little girl's waist, and held a lump of plump up.

The little girl's face was slightly red, she resisted a little, and let her do it, and wrapped her arms around Jiang Xingchen's neck with both hands, and said in his ear: "Big wedding...... Not this year!"

After speaking, the little girl turned around, giggled and escaped from Jiang Xingchen's arms.

"Why?" Jiang Xingchen asked in a daze. The hand is still in a grasping position. He always thought that the little girl would definitely set the big wedding date this year, after all, the two are already husband and wife, of course, they must get married as soon as possible.

didn't expect the little girl to give herself a surprise.

"It's not that I don't want to, it's that we have too many things to do this year......" The little girl sat back next to Jiang Xingchen. He pressed his hand on his chest and said in a low voice: "This year, the territory has developed rapidly, so let's not talk about construction." Planting, breeding. Tourism, mining. The production of transportation, paper, soaps, perfumes, spirits, etc., has increased dramatically, and the corresponding personnel management has become more complex. Now the Star Leader, counting the orcs, has 15,000 permanent staff members alone. These people have to manage ......"

"Now I'm detailing and concretizing all my work, and I'm cultivating people in every aspect. And I want to hold another festival this year to make up for the loss of summer...... Didn't my brother say that he was going to sell a batch of demon beast meat, and it was just right to plan together!"

The more Jiang Xingchen listened, the more unhappy he became, and finally his face sank and said, "You have said it, no matter how important the work is, it can't affect the body." Can that affect our marriage? You can't finish your work, but you can only get married once!"

"I know!" Mei'er gently kissed Jiang Xingchen's face and said, "It's not just me who is busy! I'm afraid my brother won't have time! The shipyard is intensifying, and there are still thousands of miles of roads under construction...... We need to study the rubber here, and there is another accident in the desert of the world's commercial houses...... Plus, when the weather gets cooler, you'll have to go to the ice fields!"

"Huh?" Jiang Xingchen was stunned, he had just come back, and he hadn't had time to tell the little girl about going to the ice field.

In an instant, Jiang Xingchen thought of the problem, it must be the old man who found Mei'er first. Tell her how good the plum blossoms are, and let her come over to persuade Jiang Xingchen to go to the ice field this winter.

Thinking of this, Jiang Xingchen asked, "Did the old man tell you what is the benefit of eating plum blossoms to my body?"

"Yes, the old man said, the genius earth treasure improves people's physique, my brother has eaten the leaves of the ice lotus and the lingzhi before, what if it is ...... Ah~" halfway through speaking, Mei'er reacted suddenly, and hurriedly covered her mouth with a scream.

As Jiang Xingchen expected, it was the old man's idea, and he had asked Jiang Xingchen when he would leave before. But Jiang Xingchen didn't give him a definite answer. He didn't say anything on the surface, but he was very anxious inside. So when I came back, I found Mei'er, exaggerated the benefits of plum blossoms, and said it again.

Mei Ran heard the old man's thoughts, especially when he mentioned that plum blossoms are good for improving Jiang Xingchen's physique, he immediately made a decision and immediately came back to persuade Jiang Xingchen.

"It turned out to be this old thing! I said that Mei'er is looking forward to the big wedding every day, how can she push it back!" Jiang Xingchen secretly scolded in his heart: "Old thing, you lied to me once on the road, see how I clean you up this time!"

"Brother, you frame me!" Mei'er gently hammered Jiang Xingchen's chest.

"Hehe, little girl, you're still a little tender when you fight with me...... Come, let me see if you've grown again!" Jiang Xingchen smiled like a big demon king and stretched out his sinful hand.

"Ahh

"You can't run away~" Jiang Xingchen then pounced. Soon the slapping turned into a rapid gasp......

That night, after thinking about it, Jiang Xingchen still agreed to postpone the wedding later. As Mei'er said, they were too busy this year to have a lot of time to elaborate on their wedding.

Jiang Xingchen didn't want to marry the little girl simply, even if he wanted to be simple, his friends wouldn't agree.

"Then let's talk about it after we are busy this year!" Jiang Xingchen tightened the little girl's head into his arms, and stroked her smooth satin back with his left hand.

The tired little girl smiled when she heard this, closed her eyes and lay on his chest......

I don't know if it's the little girl's crow's mouth, Jiang Xingchen was really busy in the next few days, all kinds of affairs came one after another, and he was so busy that he didn't even have time to design a steam engine.

First, Moon Shadow came and asked Jiang Xingchen to send someone to receive a small cold iron ore. This is the right thing, the star leader has a great demand for cold iron, of course, it can't be delayed.

But it's really a bit troublesome to send someone now, and after thinking about it, Jiang Xingchen sent someone to find Sun Sanqiang. Now that the business of Xingchen Teahouse is stable, Sun Sanqiang has also cultivated a group of people, so there is no need to stare at it all day.

However, when he went to work in the Moon Shadow Kingdom, he also had to ask Sun Sanqiang's opinion.

He was quite happy to go to Sun Sanqiang in the Moon Shadow Kingdom, to be honest, it made no difference whether the Xingchen Teahouse had him or not in the past two years, he usually didn't go, and the people below could handle it, all he had to do was to hand over the accounts to Grandpa Fu.

"Brother Sun, I can't give you personnel! If you need manpower, you can go over there to recruit! Or you can directly bring people from your Sun family, the treatment is preferential, you look at the arrangement...... If you don't want to recruit too many locals, go to Nanjiang Ling to see if there is a suitable one!"

"Brother, don't worry, you will take care of it here, I promise to do it properly, and I will transport the cold iron back as much as possible!" Sun Sanqiang said.

Jiang Xingchen laughed, said please, and asked Grandpa Fu to give Sun Sanqiang a sum of money......

As soon as this matter was settled, Qin Manwu also sent a letter, asking him when he would go to see the situation of the volcano!

The volcano can't be solved by sending someone! Jiang Xingchen has to go there himself...... But now that he is designing a steam engine, how can there be time!

Jiang Xingchen thought about it for a while, and felt that rubber production could not be studied before the power was solved anyway, and sulfur could not be used for the time being, so he wrote back to Qin Manwu and told him that he couldn't leave in the next stage, and he would contact him when he came back!

After this matter was finished, before Jiang Xingchen could continue to study the steam engine, Dingbei Hou came in person and brought thousands of people.

He came this time to escort the seized white phosphorus, a total of hundreds of small jars. Because Jiang Xingchen specially instructed him to handle it with care, and he must not open it, what was it like when it was seized, and what it is now.

When all these jars were handed over to Jiang Xingchen, Dingbei Hou breathed a sigh of relief. This way, he was really frightened.

In the process of arresting the sacrifice, someone on the other side ignited white phosphorus and burned dozens of people on the spot. This thing is extremely fast-attached, and it is poisonous, and it will be fatal if it is touched in a larger area.

Jiang Xingchen originally thought that the Emperor would leave these things, but he didn't expect to send them to himself. Before he had time to think about it, Jiang Xingchen immediately disposed of these white phosphorus! Each jar was filled with cold water, and then ordered someone to bury it in the ground for storage.

Fortunately, Dingbei Hou sent the things to see his daughter, otherwise he would have been shocked to a cold sweat when he saw that there was still a way to deal with it......!
