"I obey the order, and I will tell them when I go back."

Guo Hao nodded. The new crops have been planted. Whether it is successful depends on autumn. The previous Chameng rice increased half of Bianliang in Huaibei. Now the Chameng rice has been planted in Jiangnan. It is already predictable to have a bumper harvest.

"By the way, is there any new progress in the Geju Academy? Is the assembly line construction completed? Cannons should be mass-produced, right?"

Guo Hao had many ideas in his mind, but the development of science and technology took time. When Guo Hao first established the Geju Academy, no one was optimistic about them, and some even opposed it, saying that the Geju Academy was not doing its job properly.

However, with Guo Hao's strong advancement, the Geju Academy has initially completed its transformation from dozens to hundreds, from small workshops to large factories.

At one stop in Jiangnan, the cannons made great achievements. The soldiers of Shu and Tang had never seen them before. Their deterrence is far greater than the lethality, which means that the fear effect is relatively strong and the physical damage is not much.

When the generals learned the power of the cannons, they all rushed to Guo Hao to ask for it. This was a huge weapon to capture the city, and it would be much easier to attack the city with him.

But Guo Hao can give cannons, but there are restrictions on cannon shells and will not be issued during wartime, so the generals can only enjoy the cannons.

"Report to Your Majesty, the Geju Academy has made 36 cannons, of which 16 are left in Bianliang, and the remaining twenty are Badong five gates, ten gates in Yanyun and five gates in Lingnan."

Guo Hao nodded. He said he had arranged it in a certain proportion. Now that there are cannons everywhere, it is not so easy for other countries to invade.

"By the way, where is the musket, how are you studying?"

"This... Your Majesty should go and see it yourself, I can't understand it."

"good."

So Guo Hao came to the Gewu Academy in the south of the city. He was guarded by heavy troops at the gate of the Gewu Academy. When he saw Guo Hao, he saluted him one after another.

When I walked into the Geju Academy, I saw a row of houses in the north, surrounded by walls on both sides, a huge open space in the middle, and various instruments were placed on the west, including agricultural tools and weapons, and many things that were not common in later generations.

On the east was a shooting range, and I saw a man standing there, holding a musket in his hand aiming at the target. With a sound of touching, the target was intact, but the man was a little dirty.

"Is it still not possible? Is the proportion of gunpowder wrong? What does the force that Your Majesty mean..."

Guo Hao walked closer, took the musket and looked at it. The man realized that he saw that Guo Hao was coming.

"My minister Zuqing has met Your Majesty!"

"Zu Aiqing is exempt from courtesy, is this musket still not good?"

"Return to Your Majesty, what Your Majesty asked for was launched. We have already thought of a solution. The musket has actually been completed, but the accuracy and range have not met Your Majesty's requirements."

Guo Hao refused to comment after hearing this, and looked at the gun with his backhand. The others were startled, but Zu Qing had no reaction.

"Your Majesty be careful..."

"The barrel has no rifle, so the accuracy is definitely not high, and the range depends on the power of the gunpowder. There should be no big problem when adjusting the proportion of the gunpowder appropriately!"

"Rifle... I dare to ask what the rifle is said by His Majesty..."

The so-called rifle, also known as a duplex line, is called a windmill, because its cross-sectional shape is similar to a windmill, also known as a windmill line. The function of rifle is to give the bullet the ability to rotate so that the bullet can still maintain a certain direction after it is out of the bore.

Guo Hao said and gestured, Zu Qing was stunned. Guo Hao seemed to have no idea, so he simply squatted on the ground and drew it.

"If there is rifling, then preparation will be greatly improved..."

The emergence of rifle should have been in the fifteenth century. Guo Hao proposed this concept in advance, but no one understood it at this time.

Guo Hao is not a military fan, and he has only a little understanding of the composition of guns. Many of the things in the Jujube Academy are all ideas he proposed and then handed over to specialists to study.

"Your Majesty, I seem to understand this principle, but our existing craftsmen seem to be unable to create it."

Guo Hao sighed and said, "I don't know, you see, the barrels are welded and the strength is not enough. It will definitely not work after a period of time.

You must look for ore to speed up the melting of iron and increase the strength of iron. Otherwise, the fire gun made is better than a fire stick!"

Guo Hao was anxious, but there was no way out. Although he had studied chemistry, he had never learned steelmaking.

Zu Qing lowered his head and said yes. At this time, the two of them walked out of Physics. One of them was a descendant of Lu Ban. He was invited by Guo Hao to the Jujube Academy.

Another surname is Li, who is good at chemistry and is not very famous in history. He is a good friend of Gongshu. The two are the heads of the Gewu Academy.

"Publicly surrendered to Dan, Li Jun has met Your Majesty."

"You two dear friends are exempted from courtesy. I will come and see how this musket is doing. It seems that it is still not good now. You must continue to work hard."

"Abide by the order!"

Guo Hao said, and suddenly saw white smoke coming out of a room, which didn't look like it was on fire, Guo Hao couldn't help but feel moved.

"That room is..."

Li Jun said: "When you go back to your Majesty, the T-shirt room is studying what Your Majesty said. I heard that it has already taken shape. Your Majesty might as well go and take a look!"

The steam engine has taken shape!

One sentence made Guo Hao feel refreshed. You should know that the emergence of steam engines is a cross-age invention and the emergence and improvement of steam engines have promoted the development of social and economics.

If the steam engine can be invented successfully, the train will not be far away. Once a train is available, the transportation efficiency will be greatly improved.

Guo Hao came to the T-shaped room and felt a heat as soon as he entered, like a sauna. There was a piston linkage next to a boiler, which was particularly simple.

When the two of them saw Guo Hao coming, they wiped the sweat from their faces and saluted Guo Hao. One of them said excitedly: "Your Majesty, I didn't expect that this water vapor could really make the machine move!"

“…”

It can be said that the greater the hope, the greater the disappointment. Guo Hao thought too much for a moment, so he would not mention the loss in his heart.

I don’t know if he can board the train in his lifetime, so don’t think about cars and planes. At this time, there was a burst of exclamation from outside. Guo Hao turned around and saw something floating in the sky.

"Hot air balloon! You made this thing!"

Guo Hao's eyes lit up. It seemed that the Geju Academy was not without achievements. The emergence of hot air balloons represents air supremacy.

Gongshu Dan said with a smile: "Your Majesty's idea is indeed a clever one in the sky. Our Gongshus have only been able to make kites before. Although we can also send people to the sky, we are far less safe than hot air balloons."

Guo Hao looked at the hot air balloon and suddenly felt a little confused. He lowered his head and asked, "What do you use for fuel?"

"When I go back to your Majesty, I traveled through mountains and rivers and once found a gas in a swamp, which burned when it encountered fire, which was very scary.

Later, His Majesty asked us to sit on hot air balloons. We used a lot of fuel, but they didn't work. Later, I remembered that kind of gas."

"That's biogas!"

"It's true that your Majesty calls me."

Guo Hao was very happy and patted the two of them on the shoulders, but then his smile froze. It turned out that the hot air balloon suddenly fell down.

Guo Hao was shocked and ran out quickly. When he walked closer, he saw that they used a large airbag to load biogas. The unliquefied biogas was very large and could not contain much.

Guo Hao, who was just thinking about whether to try it, was immediately thrown into cold water. How dare he do this? If he doesn't do it well, he will become the first emperor in history to be killed!

"Well, take it slowly. Although the hot air balloon has been successful and there is fuel, this airbag cannot do it. It must be made of iron can.

In fact, all the gas we smell can be liquefied under a certain pressure, and the volume of the gas will be greatly reduced after liquefied, so that we can bring enough fuel to the sky."

In recent years, Guo Hao has often come to the Jujube Academy. At the beginning, these people didn’t even understand some basic concepts, but Guo Hao taught them a little bit.

The state of matter in physics, as well as concepts such as volume and pressure, are all instilled by Guo Hao bit by bit. This is equivalent to him leading a group of elementary school students to do scientific research, and it is impossible to be impatient.

"Yes, why do we forget this? A pot of water can produce a lot of steam. The reason is that the boiling point of each substance is different. His Majesty said it!"

For some reason, Guo Hao suddenly felt like teaching students, and it was a group of poor students. Physics and chemistry were indeed a bit difficult for the ancients, and Guo Hao had no choice.
