"Failed again, damn steam engine!" Wang Shu, who had just turned thirteen, kicked the steaming big iron guy in front of him fiercely, but he bared his teeth in pain, jumped and screamed while holding his feet, causing some of the young people around him to laugh, but then these people showed a look of frustration, because they had experimented countless times, but the steam engine they made was always unsatisfactory and had no practical value at all.

"Haha, Shu'er, you're playing with a child's temper again, isn't it just a failure, it's a big deal to start all over again, do you need to lose your temper like this?" At this moment, Zhao Yan walked in with a big smile.

This is the branch of Gewu College established by Zhao Yan in Guangzhou, which is certainly not comparable with the capital in terms of scale, but it has also attracted many students from the south to come to study, although Shu'er is young, but he is a genius, and has deep attainments in physics, chemistry, and arithmetic, and has the title of professor in several disciplines in the college.

However, Shu'er came to the academy mainly not to teach students, but to get the steam engine out according to Zhao Yan's instructions, for the steam engine, a machine that can change the world, Zhao Yan is also very coveted, and has long wanted to invent it, and the principle of this thing is not complicated, Zhao Yan himself understands.

However, it is one thing to understand the principle, but it is another thing to make a physical object, and soon Zhao Yan found that the steam engine has high requirements for steel technology, at least in the era of the Great Song Dynasty, it is not easy to make it, even if he personally participated in the manufacture of it has also failed many times.

In this case, Zhao Yan really didn't have the time or energy to spend on inventing the steam engine, so in the end he handed over this task to Shu'er, and asked him to recruit a group of extremely talented young people in the Guangzhou branch of Gewu College, and also mobilized a group of experienced craftsmen to assist Shu'er, but after such a long time of research and adjustment. The steam engine that was built still had problems in all aspects, at least not in practical use.

"Uncle, this steam engine is too troublesome, why don't you let me study the generator!" Wang Shu saw Zhao Yan come in, and walked over angrily at the moment, after Zhao Yan made a hand-cranked generator. I gave it to him to make a toy, and as a result, this little guy was very interested in generators, and he made a hydroelectric generator before, which was actually a generator driven by a waterwheel, but this kind of generator was very primitive, and the current emitted was very unstable, and there was no practicality at all, so Zhao Yan felt that the steam engine was more practical.

"Later, the steam engine is the mother of industry. Only by inventing the steam engine, there will be greater progress in other aspects, and various processes will be greatly improved, and when the steam civilization develops to a certain height, your generator will have a greater use, so during this time, you still honestly study the steam engine! Zhao Yan unceremoniously patted Wang Shu's head, his words may not be incomprehensible to many Song people, but Wang Shu was brought up by him since he was a child. The education he received was also the education of later generations, so he didn't have to worry about the problem that the other party couldn't understand.

Although Wang Shu is young. But he was very precocious, and he could understand Zhao Yan's words, but he was a young man, even if he knew that what Zhao Yan said was very reasonable, he still couldn't help but kick the steam engine again with some chagrin, and as a result, he grinned in pain again.

Zhao Yan was also very indulgent to Wang Shu. It's not strange to see him lose his temper with the steam engine, in fact, this can't be blamed on Wang Shu, after all, after countless failures, anyone will have a temper, not to mention that Wang Shu is only a thirteen-year-old child.

Wait until Wang Shu calms down. Zhao Yan then began to ask him about the reason for the failure of the steam engine, and found that it was nothing more than the old problem before, the first is that the materials are not up to standard, and the quality of the steel is not good, resulting in the steam engine making some steel components unable to withstand the pressure and deformed, or even broken, but this problem is easy to solve, now Wang Shu and they are using good steel from the south, although the quality is good, but it is still not as good as the steel produced in Qiongzhou, Zhao Yan has asked people to transport some, and this problem should be solved by then.

In addition to the quality of the steel itself, the most important thing is actually some processes themselves, such as the size of some components, which leads to poor operation of the machine, which is more likely to damage the machine. Finally, there is a cylinder leakage, this problem is actually an extension of the previous two problems, because the cylinder manufacturing is unqualified, so the problem of air leakage is very serious, resulting in the steam engine can not reach the expected power at all, and naturally there is no practical value.

For these problems, Zhao Yan can only try to solve them with Wang Shu, he can find better steel compared to the quality of steel, but some problems he can't help, such as the process, he almost doesn't know anything about these, although he knows that there are machine tools in later generations, but he has never seen it with his own eyes, let alone knows how it works, and even if he knows, he may not be able to build it, so these problems can only be solved by the craftsmen of the Great Song Dynasty.

Zhao Yan accompanied Wang Shu and they studied the steam engine for a few days, and by the way, he gave a few lectures in this branch, although the Guangzhou branch was not established for a long time, but because of Zhao Yan's relationship, many young students came to study, and Zhao Yan was even more pleased that Guangzhou is a seaport, and businessmen from all over the world are haunted here, so the mind here is more open-minded, and more people are willing to accept what he said. Many people are vying to send their young children to the branch of Gewu Academy.

Seeing so many students coming to study in Gewu Academy, Zhao Yan was also very happy, and hurriedly sent a letter to Shen Kuo, asking him to send more professors or lecturers to come, otherwise he would not be able to recruit so many students.

"Uncle! There is a breakthrough, and the quality of the steel you sent is finally qualified! On this day, Zhao Yan was discussing with Xu Yuan about the training of the new recruits of the water division, but Wang Shu suddenly ran in with a shout, with an excited expression on his face.

"Oh, really?" Zhao Yan also stood up excitedly when he heard this, some time ago, Qiongzhou sent a shipload of good steel, all of which he gave to Wang Shu and they used to study the steam engine, Hu Yanping wanted to go to build some weapons and was rejected by Zhao Yan, and now he finally saw the effect.

"Of course it's true, the quality of the steel is indeed very good, and some master craftsmen have finally improved some skills, and now the steam engine can barely turn, and it has been turning for almost an hour now!" Wang Shu jumped and jumped happily, after studying the steam engine for such a long time, he finally had the hope of success, no wonder Wang Shu was so happy.

"Haha, look at Shu'er, you are happy, but I also heard that third brother, you are very interested in that steam engine, I wonder if you can let me also see what it looks like?" At this time, Xu Yuan also said that the research of the steam engine has been kept secret, in fact, even if it is not confidential, not many people will pay attention to it, but Xu Yuan has occasionally heard Zhao Yan mention it, but he has never had the opportunity to see the steam engine with his own eyes, and today he saw Wang Shu so happy, he also wanted to see it.

"Uncle, it's great if you want to go, uncle, let's go together, I'm worried that the steam engine won't be able to turn for long!" Wang Shu was excited at this time like a child who showed his favorite toys to others, but strictly speaking, he was indeed a child.

Zhao Yan was also impatient to see the operation of the steam engine, and then came to the innermost courtyard of Gewu Academy with Xu Yuan, which was the place where Wang Shu and them studied the steam engine, Zhao Yan and the two had not yet entered the courtyard, and they heard the sound of "boom" inside, this sound was both familiar and unfamiliar to Zhao Yan, and similar sounds could often be heard in some factories in later generations, which was one of the most powerful driving forces for industry in later generations.

Xu Yuan was also very curious when he heard the loud noise in the yard, and immediately followed the excited Zhao Yan into the yard, but as soon as he entered the yard, he was startled, only to see that under a shed in the yard, a thing like a metal monster was sitting there, swallowing fire and clouds from time to time, and it would make a loud noise, which was exactly the same as the legendary monster.

"Good! That's great! Zhao Yan walked a few steps to the steam engine, watching the huge flywheel rotate under the drive of the steam engine, which made Zhao Yan seem to see the future development of industrial civilization, although the road must be very long, but as long as he brings the industry to the right track, the next thing is not something that can be stopped by manpower.

"This ...... This big iron guy screams quite loudly, but what's the use of it? Xu Yuan suddenly said at this time, although he was erudite and talented, he could not imagine the significance of the steam engine anyway.

"Brother Xu, do you remember when that person took me away because he thought I could help him regain the country?" Zhao Yan suddenly whispered to Xu Yuan at this time, what he said was naturally the incident that Xu Dezu arrested him.

"Naturally remember!" Xu Yuan glanced at Zhao Yan suspiciously, wondering why he suddenly mentioned that incident?

"Hehe, speaking of Brother Xu, you may not believe it, in fact, that person did guess correctly, if I really use it for him, then I will definitely have the ability to help him regain the world, and the steam engine in front of you is one of the weapons that can help him regain the world!" Zhao Yan smiled very confidently and said that the appearance of the steam engine will mark the beginning of a large industrial civilization, and it will definitely have a huge impact on the society.

However, as soon as Zhao Yan's words fell, the roaring steam engine suddenly "collapsed", and then a stream of steam erupted, and it actually stopped. (To be continued......)
