In ancient times, there was no department specifically responsible for scientific research, and some inventions made could only be considered personal behavior. If they had a driving effect on society, the government might have used this person as a free agent.

However, as a modern person, Yang Fan has a special liking for the development of scientific research. In his opinion, if an era or a nation wants to develop, it must be closely related to scientific research. After all, who would be willing to walk if he can take a bus? Yang Fan has been instilling this simple and clear idea in the people around him with his spare time.

This is not to cultivate lazy people, but to discover labor and develop new thinking. Only by daring to think can you do it. If you don’t even dare to think, then who will do this?

In the first year of Jian'an, Yang Fan appointed Jia Xu, Xun Yu and Gao Shun's departments to be responsible for the site selection, construction, and security of the scientific research office.

After more than a year, the scientific research office has begun to take shape and is located in Longshan southwest of Jinyang. Now, the area around Longshan, which is dozens of miles is marked as a forbidden area by Yang Fan. No one can enter it without permission without Yang Fan. Those who violate the order will be taken away by Diting Camp and questioned strictly, and the final outcome will be unavoidable.

Therefore, the people of Bingzhou all know that there are two places that cannot be visited in Bingzhou, one is Huashao Mountain and the other is Longshan.

On this day, Yang Fan brought Guo Jia, Xun You and others to the periphery of Longshan. After layers of checkpoints and inquiries, he entered Longshan.

Guo Jia climbed the stairs and asked in fear: "Is this what it looks like in Longshan? It's similar to other peaks. How can it make it mysterious? It makes me worry for a while."

Xun You smiled and said, "Yongxiao, you have always been very brave. Why? Are you still afraid of coming to Longshan?"

After hearing this, Guo Jia rolled his eyes at him and explained angrily: "Gongda, think about it, this place has been marked as a military forbidden area by the lord, and there must be some things that cannot be spread out in it. Now that I have come in, will the lord let me stay in Longshan like this using this reason? I am not afraid, I can be purified for a few more days. If you stay, will the sister Xu in your family agree?"

Everyone was immediately laughed at Guo Jia's words, and Yang Fan was also full of black lines and said to himself that Guo Jia and Zhang Liao are really a pair of treasures. Two people, one literary and one martial, can add vitality, but sometimes, their operations really make Yang Fan a little angry.

"Okay!" Yang Fan grinned and said, "Since Fengxiao is willing to contribute to our army, that's great. Let's do it. I'll approve it. Fengxiao, stay in Longshan and assist Ma Jun in doing things. I'll pick you up again in a year, how about it?"

Guo Jia's face froze suddenly, and he tried to please Yang Fan repeatedly, saying, "Lord, you don't know my character. If I really stayed in this place where birds don't poop for a year, wouldn't I be driven crazy? No, no, even if I agree, my Wudie will not agree. Even if my Wudie agrees, my father-in-law will not agree. He is still waiting to hold his grandson!"

Jia Xu joked: "When Huang Hansheng wants to hold his grandson, he will hold Huang Xu's family first. Your family has to be in the back row!"

Guo Jia laughed and said, "That's not necessarily the case. If my family comes out first, of course I will carry my family first."

Yang Fan and others walked and stopped all the way. The closer they got to the mountains, the more numerous the guards were. It was not an exaggeration to say that they were three steps and one whistle in five steps. Everyone's expressions gradually became serious. After all, no one would laugh in front of serious matters.

Guo Jia said astonished: "I'm good at it. This guard is not as good as the palace, right? What exactly is there?"

Xun You nodded and replied, "I want to know too!"

Soon, everyone walked to a castle. The castle covers a small area and looks like hundreds of acres.

It was also the first time Yang Fan came here, so he quickly smiled at Jia Xu and said, "Wenhe, please introduce it to us all, introduce it!"

After hearing this, Jia Xu stepped forward a few steps, pointed to the castle in front, and said proudly: "This place is called the Scientific Research Office, which is the top priority of our army. It is responsible for the research and development of military and civilians. The Scientific Research Office covers an area of ​​600 acres, in a hexagonal shape, divided into six floors above the ground and six floors underground. They are all made of bluestones that are 10 feet square. They are very strong and wear-resistant. There are ditches dug along the edge of the city, which are 10 feet wide and ten feet deep. The trenches are covered with sharp trenches, and there are highly toxic on them."

Guo Jia stretched his neck to look at the sharp moat ditch, and felt his scalp numb and exclaimed: "Awesome, amazing, this just glanced at me, and I felt timid!"

Xun You frowned and asked, "If the enemy burns it with fire, then this scientific research office will turn into a huge oven in an instant!"

Guo Jia patted Xun You's arm and replied contemptuously: "You are stupid. Look at the tree closest to us, which is more than a hundred feet away, right? Look at the guards? If the enemy really climbed up Longshan with wood, then Zhongdaying outside Jinyang City will also arrive?"

Xun You defended himself: "What if it rains? What should I do?"

After Jia Xu whispered a few words to a soldier beside him, the soldier hurriedly ran into the scientific research mansion. Soon after, he saw the top floor of the scientific research mansion slowly extending out the cover. These covers were shaped like umbrellas, tilting from top to bottom and outward, and stopped until they completely covered the city ditch.

Jia Xu smiled and said, "This design, imitated by an umbrella, is made of wet cowhide. It not only prevents rain from falling into the pit, but also effectively resists the attacks of bows, crossbows, arrows and small catapults."

Guo Jia spread his hands and smiled at Xun You, "Look, I knew that with Jia Wenhe, I naturally took everything into consideration!"

Yang Fan had been here for a quarter of an hour, but Ma Jun did not come out to greet him. He immediately said in suspicion: "Where is Ma Jun?"

Jia Xu smiled bitterly when he heard this, "Lord, that Ma Jun is really a fool. Not long ago, didn't you give me a wheel design drawing? I guess Ma Jun is still studying that thing now!"

"Roller? What kind of rotor? Is it a wheel?" Guo Jia was stunned and wondered: "Why do you study that thing? Could it be replaced with iron?"

Yang Fan and Jia Xu were stunned when they heard this, and they all turned their heads to look at Guo Jia with incredible expressions. It can be seen that Guo Jia had guessed the materials of the wheel just now.

Guo Jia was embarrassed to see, grabbed her head and asked, "Why are you looking at me with this expression? Am I guessed right?"

Yang Fan looked at Guo Jia seriously, and after a while, he murmured thoughtfully: "It seems that it is time to consider it, and let Fengxiao come to the scientific research office to help!"

When Guo Jia heard this, his face was full of bitterness and he didn't know how to reply. Xun You walked to Guo Jia, reached out and patted Guo Jia on the shoulder, and said earnestly: "Fengxiao, do you still dare to show off in the future? Are you caught?"

The group walked into the scientific research office. First, there were civilian scientific research results on the first floor, including water trucks that drew water from low to high, iron agricultural tillage tools, and a series of scientific research inventions closely related to people's lives. Some of them were invented by Ma Jun, and some were improved based on the past; the second floor was military equipment, ranging from a dagger to a pair of armor, everything was available, and their styles were different from the equipment in the current military.

As soon as we arrived at the first floor, everyone felt nothing in their hearts. They thought that with these things, the lives of the people would be more convenient. After reaching the second floor, everyone's eyes could no longer move with the equipment, especially the generals in the army such as Dian Wei and Gao Shun were even more stunned and saliva was flowing.

Gao Shun pulled Jia Xu and asked anxiously: "Wenhe, do these armies need to be equipped in the army?"

Jia Xu smiled and said, "That's natural, and these are all finished products. However, there are still some defects in mass manufacturing. Therefore, it does not produce energy and can only be equipped with officers above Dub's level."

Gao Shun picked up a sword casually and shouted in surprise: "This...this knife is so light?"

Then, Gao Shun pulled out his sword and hit each other with his hands several times. He saw that the new sword had a small gap, and Gao Shun's sword also had a gap.

Gao Shun was shocked and said in surprise: "This... my knife is made of iron. Although I dare not say that iron is like mud, ordinary swords are also difficult to destroy. After just a few strokes, the gap broke out?"

Jia Xu said helplessly: "Zhongyun, your sword is specially made, how can it be compared with ordinary swords?"

Yang Fan carefully observed the two swords in Gao Shun's hand, and saw that although the new sword broke out of the gap, it had not broken. It can be seen that the sword has good toughness, and it was even more difficult to break through several impacts. The sharpness of Gao Shun's sword can be imagined.

Seeing Yang Fan thinking, Jia Xu quickly spoke out and explained to him: "The iron ore that created a new type of war knife is mined from the Heishan Mountains. Because it contains many impurities, it still lacks in quality. However, Master Zheng Hun is already preparing to solve this problem."

Yang Fan was stunned when he heard this and said suspiciously: "Zheng Hun?"

Jia Xu explained: "Well, Zheng Hun, a native of Yin Kaifeng, Henan, is very good at making equipment. His brother Zheng Tai once conspired with Gongda to Dong Zhuo. However, when the matter was revealed, they went their separate ways. The Zheng brothers were also loyal and righteous. At the beginning of the year, Zheng Tai was seriously ill, so the two brothers went north to find Gongda and prayed that Gongda would come forward to plead for Brother Zhongjing to take care of him. After he recovered from the illness, the Zheng brothers surrendered to the lord for his life-saving grace. Zheng Hun came to this scientific research office and was also recommended by Gongda to me."

Yang Fan showed surprise on his face. He really didn't know that something happened. Then he turned to look at Xun You and joked: "I didn't expect Gongda to have such a side. It seems that Dong Zhuo did it too much and was so angry!"

Old Xun You blushed and replied, "That matter has not been done either, so he dare not mention it in front of his lord!"
