Zhuge Liang, Ma Jun, Pang Tong, Xu Shu, Wang Lun and others all knelt on the ground, not daring to look directly at Zhang Yan.

"His Royal Highness King Yan, please calm your anger, your subordinates and others have indeed not had similar problems in the process of experiments. Since King Yan is not satisfied with these weapons, then his subordinates will improve them. Zhuge Liang said loudly.

Zhang Yan said: "You all get up, these three new weapons, the crossbow still needs to be improved, and the fire gun and artillery must be recast." I have made it very clear to you that what I want is not so simple, and you should not come to perfunctory me. If any of you don't understand it yet, I can explain to you a little more about the principles of firecrackers and artillery. ”

Subsequently, Zhang Yan and the others returned to the hall, and Zhang Yan once again explained some knowledge of firearms and artillery. Zhuge Liang and others are the first time they have come into contact with these new things, and it is inevitable that they will be a little confused, but in Zhang Yan's detailed elaboration, some basic concepts have probably been formed in the minds of these people.

However, Zhang Yan was still a little uneasy, so he decided to live in Puyang, personally participated in the research and design, and prepared to create the first real fire gun by himself.

With Zhang Yan's participation, the research and design of firearms have also been much faster. Zhang Yan is very familiar with guns and ammunition, although he does not know how to make them, he has never eaten pork, and he has also seen pigs running, crossing rivers by feeling stones, and then making firearms, and personally supervised and guided every process. Some parts of firearms could not be made under existing conditions, but the clever Zhang Yan replaced them with something else.

After seven days of unremitting efforts, the first fire gun in history was perfectly cast.

It is said to be a firearm, but it is actually a replica rifle. Stock, barrel, trigger. The whole nine yards. Even the small parts inside the gun are very well equipped to prepare for firing.

However, due to the lack of jishu, as well as the lack of items, coupled with the urgency of time, Zhang Yan only minted a front-loading rifle. However, then launch on the device. However, great achievements have been made, and it no longer relies on ignition with fire, but uses flint for firing.

Therefore, the rifle cast by Zhang Yan this time is a flintlock rifle.

The gun was about 110 centimeters long and 20 millimeters in caliber, and the barrel was filled with gunpowder and then a small iron marble, and when the trigger was pulled, the firing pin of the rifle hit the flint directly. As a result, a large spark was created, which caused the gunpowder inside the barrel to burn violently. And expand, zuihou formed a huge impact force, ejecting the iron marbles in front of him.

After the production of this flintlock rifle, Zhang Yan personally held this rifle several times, Zuihou gave a conclusion, the best range of this gun is 100 meters, but because there is no rifling in the barrel, the accuracy is relatively poor, in the optimal shooting distance, Zhang Yan shot ten times in a row, and only six times hit the target, of which only two hit the bull's-eye, and the remaining four were all off target.

Although this is not the rifle that Zhang Yan likes, it has to be said that it is a miracle that such a gun can be produced in a short period of time and with the existing scientific conditions.

The success of the production of the flintlock rifle has also injected a fresh blood into Zhuge Liang and other people from the Tiangong Bureau, how to increase the range, how to improve the accuracy, how to improve the speed of shooting, have become the direction they will study in the future.

At the same time, the development of firearms and their equipment in the army also became the focus of Zhang Yan's future development.

So, Zhang Yan asked Zhuge Liang and others to make a hundred rifles first, as for the artillery, it was still fired by ignition, but the barrel should be much thicker and deeper, in short, the artillery should be powerful and long-range.

After that, Zhang Yan left the Tiangong Bureau and told Zhuge Liang and the others that after the production of a hundred rifles was completed, they would send people to Pengcheng, and as for what materials were needed, Zhang Yan would try his best to meet them.

After returning to Pengcheng, Zhang Yan immediately selected a hundred people from the Jinyi Guards and asked them to be on standby at all times, ready to welcome the arrival of new weapons, and regarded the Jinyi Guards as the first people to use the new weapons.

However, this waiting time is relatively long, because the process of producing a rifle is more complicated, and the production time of a rifle is also relatively long.

In the months that followed, everything was peaceful on the land of the Central Plains, and soon the year 201 was ushered in. During the Spring Festival of this year, Zhang Yan promulgated the world, because of the accession of the new emperor Liu Feng, as well as the pacification of Hebei and the stabilization of the northern border, so the Yuan Wude was changed, and the year 201 AD was the first year of Wude.

It is also at this time that the civil and military ministers in the imperial court have a holiday of fifteen days, and after the Lantern Festival, they will start to work again, so that all the civil and military ministers who have worked hard for a year can reunite with their families and have a good New Year.

The Lantern Festival has just passed for three days, and the regent Yan Wang Zhang Yan, who has just gone to work, received a letter from Henan.

The song is written by Zhang Hong, the governor of Henan Prefecture, and thousands of words are sprinkled with thousands of words, but the general content of the song is summarized in only two words, that is, "moving the capital".

With the gradual stabilization of the Han Dynasty and the restoration of the old capital Luoyang for many years, Pengcheng is no longer qualified as a capital, although the area around Pengcheng has gradually become a large city after so many years of development, and the population of immigrants is also increasing day by day, and the Pengcheng originally planned by Zhang Yan has become more and more congested with the surge of population.

The construction of a new capital city to alleviate the differences between regions is an urgent matter.

Therefore, Zhang Hong thought about what people thought, and first presented it to Zhang Yan in the form of a song, suggesting that the capital of the Han Dynasty be moved back to Luoyang.

Weishenme wanted to move the capital, and Zhang Hong expounded the importance of moving the capital and the inevitability of Luoyang as a place of Longxing.

Zhang Yan read this letter without losing a word, and after reading it, he also had an urge to move the capital immediately.

However, Zhang Yan did not take action immediately, and thought calmly.

Now he is no longer a simple mind, a mercenary with developed limbs, in the years since he came to this shijie, with the development of many things, Zhang Yan has gradually armed his mind, he is now a person in a high position, holding the power of the whole world, and the whole body is affected, Pengcheng is his lair, if he really plans to move the capital of the Han Dynasty to another place, how much manpower, material and financial resources will be spent.

However, the geographical location of Pengcheng is indeed a little unsatisfactory, not as good as Luoyang with high mountains and dangerous obstacles, eight passes tightly locked, is a natural place of Longxing, can be attacked, retreat can be defended, and is also located in the center of the entire Han Dynasty.

Therefore, Zhang Yan specially discussed the matter of moving the capital in the early court, hoping that the ministers could give more pertinent opinions.

In the court, there have always been few voices, but as soon as the topic of moving the capital was raised today, it immediately caused an uproar.

The ministers expressed their opinions and expressed their opinions, but in the end they still gathered into two opinions, one was in favor of moving the capital, believing that Luoyang was originally the capital of the Han Dynasty, and it was only when Dong Zhuo's rebellion was encountered that it would be burned, and it was inevitable to return to the old capital.

Another opinion is against moving the capital, thinking that although Luoyang is the old capital, it has become a barren place, if you want to move the capital, you also need to build a new capital, which will cost the people and money, so it is better to expand on the basis of the original Pengcheng, which can save a lot of trouble.

The opinions in favor of moving the capital and those against moving the capital are basically half to half, and people on both sides are arguing with each other in the court,-for-tat, and chattering endlessly.

zuihou, Zhang Yan was too lazy to listen, and directly announced the withdrawal of the dynasty and the relocation of the capital, and discussed it later.

After retiring from the dynasty, Zhang Yan left Zhang Zhao, Chen Qun, Gu Yong and other confidants behind, and asked them again about moving the capital.

Chen Qun said: "It's not possible to move the capital, but now is not the time. Hebei has just been pacified, the border has just been settled, the war has just been settled, and many places need to use a lot of money. ”

Zhang Zhao and Gu Yong also have similar opinions, thinking that it is okay to move, but not now, maybe it will not be too late to move in ten years.

However, Zhang Zhao suggested to Zhang Yan that the relocation of the capital was a matter of time, so the construction of the new capital should also be customized as soon as possible, and a new capital could be built on the basis of the old capital of Luoyang.

Zhang Yan listened to Zhang Zhao's suggestion and wrote a letter to Zhang Hong, promising to move the capital, but not now, because Luoyang does not have the conditions to move the capital now, and instructed Zhang Hong to concentrate on the construction of a new capital in the next ten years, and prepare to build a new, huge capital.

At the same time, Zhang Yan specially referred to the construction of the capital in history, drew a magnificent sketch, and sent someone to send the sketch of the new capital to Zhang Hong, so that Zhang Hong was fully responsible for the construction of the new capital, and built it according to the scale on the drawings, in batches, and in stages, preparing to build this magnificent capital city in eight years.

After the messenger was dispatched, Zhang Yan then received an important message, the news was sent by Li Cai, saying that Gongsun Du had died in Liaodong, but Gongsun Kang did not hold a funeral, and secretly assembled an army with bad intentions.

After Zhang Yan got this important information, he fell into deep thought, Hebei had just been pacified, and the nomads on the border had also been hit hard by him, so it stands to reason that Liaodong at this time should have a warning and stay there honestly.

However, Li Cai's information said that Gongsun Kang was secretly assembling troops with bad intentions, could it be that Gongsun Kang was a fool and dared to commit a crime against the wind?

A moment later, Jin Yiwei sent a letter from Gongsun Du, and after Zhang Yan took it, he looked at it hurriedly and frowned...... (To be continued......)
