Operating the repeater, Zhao Xie was very excited, and tested it several times in a row to check the performance.

In a nutshell, the key to repeater performance lies in three aspects: continuous firing rate, range, and stability.

During the third test firing of the full arrows, an unexpected situation occurred, after the fifth arrow was fired, the arrows in the upper arrow slot did not fall into the horizontal slot in time, resulting in the interruption of the continuous firing.

Even in modern and modern times, it is difficult to completely avoid the possibility of accidents with weapons, such as the possibility of machine guns jamming.

Zhao Xie also found other problems, after the arrow was fired, it took two seconds to shoot the next arrow, and the continuous rate was not fast enough.

In terms of range, it can shoot up to more than 100 meters, and it can ensure lethality within 80 or 90 meters, which is basically passable.

Overall, the performance of this repeater sample can barely be put into actual combat, and if Zhao Xie is asked to score, he will give fifty points.

New inventions cannot be made overnight, and it is good to be able to do this now.

Zhao Xie said to Huang Tingjing: "The launch speed is still too slow, the shooting stability is not good enough, and the weight should be reduced a little more." Efforts need to continue to be made to improve as soon as possible. ”

Huang Tingjing said: "King, the Han army may invade at any time, do you want to make a batch to use first?" ”

The Mo family itself has no good impression of Liu Bang, and since he has served King Zhao, he naturally wants to think about the problem on the side of Zhao Guo.

Zhao Xie thought for a while and said, "I'll give you another half a month, if there can be improvements during this period, then make it on a large scale with the improved standard." ”

Immediately, he sent an order for the military department to prepare the materials for building the repeater first, so that it could be put into production at any time.

In the north of Yandi, the military capital mountain, there is the military capital here.

In later historical records, this is one of the eight Taihang Mountains. The rest are Puyin, Flying Fox, Jing, Fukou, Bai, Taihang, and Yiguan.

The military capital is about 40 miles long from north to south, and there is a Xiongguan built here, which is called Juyong Pass in the Qin Dynasty, and is called one of the nine stops in the world. When the Qin Dynasty built the Great Wall, prisoners, soldiers and forcibly recruited people lived here, taking the meaning of "migrating to mediocrity".

As early as the Spring and Autumn Period and the Warring States Period, the Yan State was controlling this mouth and guarding against the northern nomads.

Juyong Pass is related to the north and south of the ditch, the south pass is called "South Pass", and the north pass is called "Juyong Pass".

On this afternoon in mid-February, the team trading with the Xiongnu arrived at Nankou, and Du Zhen and He Xian, who had been waiting here, greeted them outside Nankou, and the team entered in an orderly manner.

After entering from the south entrance, the procession went all the way north, and stopped at the city of Juyong Pass, where they stayed for one night, and tomorrow they would leave Juyong Pass to trade with the Donghu tribe.

That night, Du Zhen received the generals and officials for dinner and discussed the specific details of tomorrow's customs transaction.

At that time, after discussing the details of the transaction with the elders of the Donghu tribe, He Yan stayed for two more days at Wei Fang's request, and told Wei Fang in more detail about the people and things in the land of Huaxia in Guannei.

After returning to Juyong Pass, He Xian has been living here, and he will not return to Xiangguo with him until the people sent by King Zhao have completed the transaction with Donghu.

The next morning, the trading team came out of Juyong Pass, in the northwest of more than 30 miles, where there was a large flat land, and the Donghu tribe had made an appointment in advance to trade there.

After arriving at the destination, the other party has not yet arrived, and everyone is waiting.

In addition to the 6,000 cavalry who were not on horseback, there were also 2,000 foot soldiers sent by Du Zhen to assist, saying that it was to assist, mainly to prevent accidents, and the possibility of the Donghu people taking the opportunity to loot could not be ruled out.

After waiting for about an hour, someone noticed the situation and listened with his ear to the ground.

"It's the sound of horses' hooves, they're coming!"

Immediately, the 8,000 soldiers who were fully armed were in good spirits, and the transaction was to be taken care of by the household department, whose duty was to guard against possible attacks. Although it was an appointment with Donghu in advance, it was difficult to guarantee that the other party would not cheat.

Soon, a large number of horses came into sight and were rushing towards this direction.

The other side was small in number, no more than two thousand by sight, and drove a large number of horses to the jogging direction. Judging from their equipment, it is not like preparing for battle, and most of the vigilance of the generals of the Zhao army has been relaxed.

The Donghu people stopped dozens of zhang away from the Zhao army, led by a man and a woman.

The man is in his early twenties, burly and strong, he is the elder's son Jin Lun; The woman is Wei Fang.

The woman shouted to this side: "Donghu came here according to the agreement with Zhao Guo in advance and traded with Zhao Guo with horses." ”

She spoke in the original dialect that she was not very fluent in.

He Yan said to Zhuo Zhongkai and the officials of the household department and the military department: "They are the sons and daughters of the elders, and there should be no accidents in the transaction." ”

He rode forward, ran to Wei Fang and said, "Princess, Zhao Guo has brought all the supplies, please check." ”

After Wei Fang said a few words to Jin Lun, he sent someone to Zhao Jun's side, and he needed to check the type, quantity, and quality of the materials traded.

He Xian rode back to the side to explain the situation, and a group of officials from the household department immediately ran to the other side, and they wanted to make a clear account of the 12,000 horses in this transaction, and to divide the 2,000 breeding horses.

Both sides sent people to the other side to check the trades.

The Donghu people are okay, and it doesn't take too much time to inspect the items loaded on the carriage.

The officials of the Zhao State Household Department had to count the number of horses, which was more time-consuming.

After a lot of effort, the number of horses was finally counted, just 12,000, and then the officials inspected the breeding horses to make sure they were okay.

After the two parties took inventory, they found no abnormalities and made a transaction.

Donghu carried the bags and boxes of supplies from the carriage to the cart he had brought, and then transported them away.

The soldiers and soldiers of the Zhao army ran to the horses, everyone got on their horses, and then drove the other half of the horses to the direction of Juyong Pass.

Experiencing it personally, witnessing it with his own eyes, and watching the transaction go smoothly, He Xian was finally completely relieved.

Before leaving, Wei Fang explained to He: "I have always hoped that I can have the opportunity to go to the Central Plains, but unfortunately I will soon become the king's woman." ”

Wei Fang's heart was full of sadness.
