Now on the Wufeng Islands, the number of craftsmen of all kinds is as many as three or four thousand, which is about to exceed the number of craftsmen in the wolf's den.

Zhen San's original name was Song Xu, and he followed him as early as when Zhen Qian was really decided, and it has been almost three years, and for Zhen San, Zhen Qian has a feeling of being a younger brother.

At this time, there were three notebooks in front of Zhen San, and the cover of the notebook was written with the four words of the principle of Gewu, the first two books recorded some memories of high school textbooks about physics and chemistry in Zhen Qian's mind, and the last book recorded some of Zhen Qian's understanding and assumptions of Gewu, mixed with some mathematical knowledge.

Zhen Qian's memory and understanding of science in his previous life are all in these three books, if Zhen San can learn this knowledge, Zhen Qian will not be of any help to Zhen San.

Zhen San just flipped through it casually, and was shocked by the knowledge recorded in the notebook, if it is said that in this era, who has the highest knowledge of Gewu, Zhen San said second, no one dares to say first, of course Zhen Qian does not count.

Zhen Qian's understanding of science is all due to the rigid education system of later generations, and Zhen San's understanding of living and applying is not at the same level at all.

Zhen Qian poured a cup of tea for Zhen San opposite, took a sip of the teacup himself, and said with a depressed face: "This is all my understanding of Gewu, if you have any questions, if you can't find the answer in these books, you can only study it yourself." ”

"Thank you for the generous gift of the master, Zhen San will not dare to forget it in this life", Zhen San's eyes flashed, and his hands were always on the three books, for fear that he would fly away as soon as he let go.

Zhen San's current expression is not at all out of Zhen Qian's expectations, when a person is obsessed with a certain thing, he is a little slow to react to other things, if he changes to a person with higher emotional intelligence, he should show gratitude at this time, and he is extremely excited, as if he is excited like such a recreation, but now Zhen San only has those three books in his eyes, and even answering Zhen Gan's words is a little perfunctory.

Zhen Qian didn't mind, he had already known Zhen San's temperament, how could he not know that this was the real Zhen San.

"By the way, Zhen San, are you really not going to go back to Datang this time?"

Zhen San only withdrew his gaze from the three books at this time, there are too many incomprehensible knowledge recorded in the books, some of which are even more incredible, spreading it will inevitably cause a sensation in this Tang Dynasty, it is impossible not to become a god and ghost, in this era, only Zhen San and a few people really understand the horror of the knowledge on it, the thoughts in his mind are rolling, thinking about the new knowledge he saw just now, his expression was a little stunned for a while: "If you don't go back, you don't dare to do many things in the wolf's den, only here do you have no scruples!" ”

Zhen Qian nodded, he knew very well why Zhen San came to the Wufeng Islands, in the wolf's den, because he was worried that the existence of the wolf's den would be discovered by the outside world, even the usual gunpowder experiments had to be carried out on thunderstorms, and even now because of the increase in the population of the wolf's den, the daily coal burning in the valley has also begun to be restricted, which made Zhen San's experiment in the wolf's den timid, for fear of being discovered by the outside world.

Although the wolf's den is located in a hidden and remote place, but after all, it is not far from the Jingcheng business road, if someone stands on the top of the mountain to look, may find some clues, no one can guarantee that the place where tens of thousands of people gather will never be a little wrong, any omission is fatal to the wolf's den.

The wolf's den is indeed a little small as Zhen San said, the valley that could only accommodate 3,000 people is now crammed into tens of thousands of people, most of whom live in caves dug in the mountain, and if it goes on like this, it is possible for the population to exceed 20,000 in a year.

Moreover, the scientific research conditions of the wolf's den have also been greatly limited, such as the steelmaking furnace can only be produced once a month, and the dust produced will go straight to the sky for a long time, and it is easy to be discovered, which is the real reason why Zhen San decided to leave ......the wolf's den.

Zhen Qian has already selected a new location for Zhen San's craftsman camp in the Wufeng Islands, and Zhen San has the space to show his strength, and he is no longer afraid of being discovered.

"Okay, you go back, if you need to ask Uncle Wang directly, he will fully support you!"

Zhen Qian had a lot of things to ask Zhen San, but seeing that Zhen San's gaze never left the three books, he sighed lightly in his heart, knowing that he was already absent-minded, and swallowed back the words when they came to his mouth.

Zhen San hugged the three books on the table tightly in his arms, turned around and was about to leave, just took a few steps and suddenly stopped, his eyes were confused and turned back: "Master, I experimented in the wolf's den before, boiling water can indeed produce a lot of force, this force can push the small windmill to rotate, if you increase the amount of water vapor, can you push the larger windmill to rotate?" ”

Zhen Qian knew that Zhen San was talking about the principle of the steam engine, before Watt invented the steam engine, the steam engine had appeared as early as the sixteenth century, the energy efficiency of the steam engine at that time was extremely low, Watt carried out a series of inventions and transformations, adding the insulation layer, lubricating the piston with oil lubrication, planetary gears, parallel motion connecting rod mechanism, centrifugal governor, throttle valve, pressure gauge, etc., so that the efficiency of the steam engine was increased to more than three times that of the original Newcohmin machine, and finally invented the steam engine in the modern sense.

After hearing Zhen Qian's theory of the principle of power, Zhen San simply connected the generated steam with the windmill according to the phenomenon of boiling water in a teapot, so as to turn the windmill for the first time without the action of wind, manpower and animal power, which was a real cross-era discovery.

Of course, this first of all excludes Zhen Qian, a descendant.

One of the biggest goals of this Zhensan to Wufeng Islands is to build a larger kettle to produce more steam and push larger windmills, so as to get rid of the status quo that has always relied on water power to propel large windmills.

Zhen Qian did not help Zhen San in more places, on the one hand, his own knowledge could not build a modern steam engine in the real sense, on the other hand, building a steam engine is a step-by-step process, in which each step is to solve the problems found before, only in this way can the industrial system in Zhen Qian's mind be gradually improved in the process of building a steam engine.

Zhen Qian didn't want to help the seedlings grow, if he really came to this point one day, there was really not much he could do.

"Your idea is very good, but this is a path that no one has ever explored, not to mention the difficulties, but more importantly, confidence and will, I send you a word, only paranoia can succeed in this world!"
