After everything was arranged, Bai Ziyun and Zhuang Zhou came to the arsenal, and now many factories have been built in the arsenal, and the clanging sound of craftsmen can be heard in the workshop from time to time.

Bai Ziyun visited the factory and found a lot of facilities and a few more machine tools, although it was still relatively simple, but it also made Bai Ziyun very relieved, it can be done so quickly, it can be seen that Zhuang Zhou has been working very hard.

Bai Ziyun said: "Machine tools need steam engines to play their maximum role, you will build steam engines with the steel mill next, with your current technology, you should be able to make a relatively dense steam engine in a few months." ”

Zhuang Zhou was embarrassed: "Master, we have been preparing for the steam engine, but the sealing ring is not easy to get, and the rubber tree mentioned in the book, we don't have this thing." ”

"Don't worry, the teacher will find a replacement, you can rest assured that you can get the steam engine out." Bai Ziyun has long known that there are certain plants in Dahan that also have rubber properties, and he has ordered people to look for them, but there is no news yet.

"No!"

"Okay, let's go see that Zhao Yu."

"Yes." Zhuang Zhou grabbed a worker and asked, "Where is Zhao Yu now?" ”

The worker smiled: "Where else can he be, he must be doing research in the research and development room." Immortal Master Zhuang, do you need me to call him? ”

Bai Ziyun said: "No need, let's go by ourselves." ”

The two walked around the factory for a while, and turned into a large room, which was quite quiet, and the researchers inside hurriedly saluted when they saw Bai Ziyun. Mouth is honored. Only a young man turned a deaf ear and drew a picture at the desk without blinking.

Bai Ziyun and the two walked closer, and the young man reacted. Hurriedly saluted: "I've seen Your Excellency." ”

"No excuses." Bai Ziyun waved his hand, looked at the young man, and asked, "Are you Zhao Yu?" ”

"Exactly." Zhao Yu lowered his eyebrows and said pleasantly.

Bai Ziyun saw that his body was weak, and his eyes were beautiful, so he had a good impression in his heart, and looked at the drawings on the table, on which Bai Ziyun drew concave lenses and lines. He smiled and asked, "Are you researching glasses?" ”

"Glasses?" Zhao was puzzled.

Bai Ziyun said with a smile: "It's the kind of glass magnifying glass used to correct eye diseases." ”

"Yes. Your Excellency, there should be all these things in the fairy world, right? Zhao Yu asked a little dejectedly.

"The thinking of all worlds is the same, and other worlds have invented. It's a normal thing and you don't need to be depressed. Bai Ziyun looked at the drawings again, nodded and said, "Well, the basic principles are not wrong. Glasses can already be made. Other researchers learned the principles of optics. I never thought of using concave and convex mirrors to make glasses, but I thought of it, which shows that you are ingenious and different. ”

"Thank you for the compliments, these ...... These are the things I should do. Zhao Yu's face was blushing, and he seemed to be a young man who was more introverted and not very good at words.

"Listen to Zhuang Zhou, you also developed a gunpowder arrow, take me to see it."

"Yes. Your Excellency, please follow me. ”

Zhao Yu's spirits perked up slightly, and he took Bai Ziyun to a spacious room. The smell of gunpowder wafted through the air.

Bai Ziyun frowned, looked around, it was quite clean, and he didn't put gunpowder or anything like that, so he put his mind at ease.

Several people walked to a wooden car, Zhao Yu patted the wooden car, and said with a happy face: "Your Excellency, this is the wooden cart containing gunpowder arrows, put the gunpowder arrows into the small hole of the wooden car, and then light the fire rope, you can launch a cart of gunpowder arrows together, and ten thousand arrows are fired together, and the power is endless." As he spoke, he took out a feathered arrow with a barrel of a cylindrical cannon tied to it.

Bai Ziyun looked at the gunpowder arrow, it was indeed no different from the gunpowder arrow at the end of the Ming Dynasty, this simple invention was too pediatric in modern times, but it was already very rare in this era, this was still not under his guidance, Bai Ziyun saw the first self-contained invention of this world.

Seeing that his face was a little proud, Zhuang Zhou suddenly felt embarrassed, slapped him on the back of the head with a palm, and said, "What are you proud of!" This kind of gunpowder arrow has long been issued in other worlds, but it has too many shortcomings and has not been popularized at all. It is too poor to use and consumes too much gunpowder. ”

Zhao Yu's face was flushed suddenly, he lowered his head, and said after a long while: "Oh, that's the case, this gunpowder arrow is indeed too gunpowder-consuming, steward, you let me wait to get a musket to save a lot." ”

"Oh?" Hearing the musket, Bai Ziyun became interested again, "You are already developing the musket, well, okay, take me to have a look." ”

"No."

The place where the musket was developed was not far away, and when you entered a gate, you entered a large factory, and there was a thudding sound inside, and it turned out that someone was testing the musket.

After everyone saluted, Bai Ziyun picked up a musket and looked at it casually, it was an arquebus of later generations, but in terms of quality, it was much stronger than the bird gun of the late Ming Dynasty.

"Let's take a few test shots." Bai Ziyun had never played with this kind of firearm before, and couldn't help but want to try it.

"No!" Zhao Yu hurriedly brought an arquebus, an arquebus, and gunpowder.

Bai Ziyun loaded the gunpowder and loaded the projectile according to the steps of the arquebus, pulled out the whole strip from under the barrel, tamped the projectile and propellant, ignited the arquebus, and pointed forward at random and pulled the trigger.

"Bang!"

With a loud bang, the lead bullet flew out at high speed, Bai Ziyun grabbed his hand, and grabbed the lead bullet that flew out, feeling the high temperature and strong impact of the lead bullet, but it had no effect on him, and easily pinched the projectile.

Everyone around him was very strange, the projectile flew out, why didn't the plank in front of him react? Where did this projectile go?

When he saw Bai Ziyun playing with a lead bullet in his hand, he was moved, and it turned out that he was held in his hand.

"Master, this ......" Zhuang Zhou quickly recovered from the shock, after all, he had seen his own master's power many times.

Bai Ziyun shook his head and said: "Don't be surprised, when your martial arts reach the first-class realm, you can also catch the projectile with one hand, the bullet of this arquebus is not much stronger than the strong bow, it can only hurt a third-rate martial artist, a second-rate martial artist can use a weapon to split, and a first-class can catch it with your hand, how can it hurt?" ”

"Isn't it useless to develop such a weapon?" Zhuang Zhou said disappointedly.

"Otherwise, second-rate martial artists are not so easy to train, and the advantage of firearms is that they can be made in batches, and ordinary people can injure third-rate martial artists when they hold them in their hands. Moreover, firearms training is also very convenient and fast, and you can become a sharpshooter after a few months of training, and it is also very easy to form an army, which is extremely lethal against an army with low martial arts. ”

"Well, the master is right." Zhuang Zhou nodded, and asked again: "Then will this kind of firearm be mass-produced?" ”

Bai Ziyun shook his head and said: "No need, this arquebus is too simple, and it is too easy to imitate, I don't plan to use firearms externally, lest someone imitate it, which is not good for our immortal sect, you must pay attention to this, and you must not leak it out." ”

Zhuang Zhou said solemnly: "Master, please rest assured, Zhou knows the importance of this matter." ”

"Well, you're all pretty good anyway." Bai Ziyun nodded with satisfaction, returned the arquebus to Zhao Yu, and asked, "Zhao Yu, are you willing to be the manager of the arsenal?" ”

"Huh?" Zhao Yu was shocked for a moment, and after a long time, he was at a loss and said, "Your Excellency, I ...... I can't do it, I haven't done it at all. ”

Bai Ziyun smiled: "It's okay, you are still young, you can learn slowly." ”

"I love to study delicate things, but I don't have the guts to manage them." Zhao Yan looked worriedly at the researchers around him, and those researchers looked at him with envy or jealousy.

Bai Ziyun glanced at the people around him, and took these expressions in his eyes, as if there was a faint rejection, it can be seen that this Zhao Yi is not good at communication and is not a very good management talent, but now he doesn't need too good management personnel, as long as he can say that the work he arranged is successfully completed, Zhao Yu is very in line with this, especially his innovative spirit, which makes him particularly fanciful.

"Okay, you don't have to excuse yourself, I believe in my vision, Zhao Yu, you also have to believe in my vision, believe that I won't be wrong."

Zhao Yu remembered Bai Ziyun's immortal identity, and suddenly perked up, thinking in his heart: "Your Excellency is an immortal, and immortals have the ability to predict, he said that I can do it, then it must be okay, I don't have to be arrogant." ”

Zhao Yu saluted and said, "No! ”

Bai Ziyun said again: "The matter of the arsenal, Zhuang Zhou will guide you for three months, and then slowly transfer everything to you, you do things well, I hope it will not disappoint me." ”

"No!" Zhao Yu looked at Zhuang Zhou on the side gratefully, this immortal master who was younger than himself had indeed extraordinary abilities, which made him admire him very much.

Bai Ziyun looked at the drawings below again, and said with a smile: "If you make the glasses, this seat will exempt you from being a slave and let you regain your free body." ”

"Xie Zunshang." Zhao Yu knelt down and kowtowed excitedly, this kind of glasses technology exists in the fairy world, but Bai Ziyun asked him to invent it, obviously he deliberately rewarded him with credit, can Zhao Yu not be moved?

"Zhao Yu, what I fancy is your innovation and research and development ability, and I hope that you can continue to innovate and develop in the future, and make persistent efforts, so that the arsenal can develop more things under your guidance."

"No!"

"Hmm." Bai Ziyun nodded and walked out of the research and development room, with Zhuang Zhou following behind.

Zhuang Zhou asked: "Is the master planning to put the glasses invented by Zhao Yu on the Baiyun Department Store for sale?" ”

"Yes." Bai Ziyun smiled again: "But although the principle of these glasses is very simple, it is not so easy to manufacture to be precise, I will get a copy of the glasses information when I go back, and you can give it to Zhao Yu." ”

"Okay!" Zhuang Zhou smiled and frowned: "Now a lot of things made in our workshop have been imitated by people outside, and many wealthy businessmen rely on this to make profits, harming a lot of interests of our immortal sect. ”

"Patent law?" Bai Ziyun frowned. (To be continued......)
