With the thunder quilt, there are still big rings and Chengxin in Cloud City, and there are many masters around Yan Ming.

He didn't think much about Liu Ling's matter, after all, it was unknown whether the two would intersect in the end.

Returning to the city in the clouds again, the city wall in the clouds is already a tall city wall of blue bricks and cement. Even the banner at the head of the city looks new.

Looking at this border city standing on the edge of the grassland, Yan Ming's heart throbbed for no reason.

At this time, Cloudsdale looked extremely solid. Yan Ming wants this solid feeling. He believed that the Xiongnu Shan was a man with a desire to conquer. As long as they see such a fortified city and don't want to conquer it, it is not in line with their style of acting.

Now in Cloud City, all you have to do is to fight the Huns.

Yan Ming's return made Wei Qing breathe a sigh of relief.

Although Yan Ming has delegated the right to use the fire thunder to Wei Qing, he still has no bottom in his heart when Yan Ming is away. After all, this thing is too fresh, and Wei Qing feels that he can't grasp it well.

Returning again, construction has begun in Cloudsdale.

According to the experience of Maolingyi, Lao Xu has already started digging huge sewers. The entire Cloudsdale has already started to build infrastructure.

Seeing the huge sewer, Yan Ming's eyes suddenly lit up.

This kind of underground building can be completely applied to the periphery of Cloud City. In other words, through large-scale underground construction, the inside and outside of the city will be connected.

It's like building a subway, a large underground construction.

The soil in the clouds is very good, which is suitable for this kind of construction. With green brick cement, it can be built little by little.

It's just a lot of work to dig into.

This idea flashed in Yan Ming's heart, and he gave it up.

With flintlock pistols and fire and thunder, it was difficult for the Huns to enter Cloudsdale. If it is said that the construction of underground passages, only the future plan in the clouds can be used.

Conspiracy in the clouds! After this word popped up in Yan Ming's mind, he decided to discuss it with Lao Xu first.

If the entire facilities in and around Cloudsdale can be completed within a year, then give it a try.

Yan Ming decided to spend a year to build Yunzhong City, and at the same time use this year to beat the Huns to hurt and cry, and they refused to give up until they did not attack Yunzhong City.

Elder Chen brought good news to Yan Ming.

In the past few days, he has been building gun barrels day and night, and he has even built three more gun barrels.

Some of the parts used to make guns were also made.

Assemble three more flintlock pistols, and take the original two to form a flintlock squad. A squad of five people, sniping the enemy's generals on the battlefield from a long distance has been able to deal a fatal blow to the Huns' army.

Yan Ran wanted to equip the female soldiers with flintlock pistols.

Yan Ming naturally did not agree.

The female soldier, in his opinion, is just a curiosity to satisfy Yanran.

With peace of mind, it took three days for Yan Ming to assemble three flintlock pistols, plus the original two, there were already five flintlock pistols.

Two of them were mounted with scopes.

A flintlock pistol with a scope for accurate shooting at long distances.

Yan Ming still asked Lou Xiaowu to choose the firearms. After all, this guy is a marksman, and he should be talented in shooting.

Lou Xiaowu's talent is indeed very good. It was revealed when he got the flintlock pistol and fired the first shot.

One shot hits a target 600 paces away and hits the bull's-eye of the target.

This kind of shooting talent made Yan Ming almost pick up Lou Xiaowu. This is a natural sniper. In this era of cold weapons everywhere, the appearance of a sniper will rewrite the course of war.

In the following days, in addition to studying the construction of the tunnel with Lao Xu, Yan Ming practiced shooting on the shooting range with Lou Xiaowu and the other four people.

Even Wei Qing will often come to touch the gun.

This famous general in history also has a high talent in shooting, although he is not as good as Lou Xiaowu, he is definitely much stronger than ordinary people.

The Huns, on the seventh day of Yan Ming's return, finally appeared on the grassland.

This time, King Zuo Xian was ruthless, and there was no small-scale harassment operation. Instead, he sent a full 5,000 Hun cavalry, wanting to take Yunzhong City in one fell swoop.

I saw the five thousand Hun soldiers who were pressed by the black outside. And all the people went up to the top of the city. Yanran's female soldiers are no exception.

Military crossbows have been distributed to every defender of Cloudsdale, along with swallow swords.

Wei Qing was already prepared for the worst, that is, if the Huns landed on the top of the city, they would start hand-to-hand combat.

The Huns, as in the past, did not launch a large-scale attack as soon as they came up.

This time, they learned wisely, and they didn't get close to Cloud City at all, and they actually stationed a thousand steps away from Cloud City.

This distance was already beyond the range of the flintlock pistol.

In the face of this situation of the Huns, the people of the entire Cloud City were under some psychological pressure.

In the past, there was no need for 5,000 people, only 1,000 Hun soldiers were needed to cross the cloud city. Now facing 5,000 Huns at one time, all of them are a little uneasy.

Even the old defenders began to be suspicious.

Only Captain Hu Qi, who didn't care with a face.

Even Wang Dajian shouted: "As long as three salvos are fired, you can nail the Huns outside." ”

Yan Ming climbed to the top of the city, took a flintlock pistol with a scope as a telescope, and looked out carefully. The Huns were preparing for a protracted war, and even set up camp outside.

"How?" In the war, Yan Ming was a layman, so he had to ask Wei Qing.

Wei Qing squatted down, pointed on the ground with his fingers, drew a picture of the city in the clouds, and said: "The Huns are here, and we have no problem holding on to it." If you want to eat them, you can't just defend the city. If Li Guang and Cheng Buzhi could be mobilized to outflank them from both sides, none of these Huns would be able to leave. ”

Yan Ming shook his head and said, "Third brother, you can't kill all of these Huns. I'm going to turn Cloudsdale into a meat grinder for the Huns. In the early stage, you have to give them the feeling that they can break into Cloudsdale with a little effort. You can't make them desperate all at once, you know? ”

Wei Qing blinked and said with a smile: "You want to use Cloud City to contain the main force of the Huns?" ”

Yan Ming said: "It's probably like this, even if you can't contain Shan Yu, you have to pull King Zuo Xian to the place of Cloud City." Lao Tzu wants them to gnaw and itch the root of their teeth. ”

Wei Qing laughed and said, "Your idea is too bad. It's time for the fire thunder to come in handy this time, right? ”

"Don't worry, the fire and thunder are for more Huns." Yan Ming said with a smile.

He believed that Cloud City would definitely be able to scratch the itchy flesh of the Huns.

A border city that can't be gnawed on is something that the Huns are absolutely not allowed to exist. Because once such a border city exists, it proves that the Han Dynasty can completely rely on the border city to advance, and there is no way out for the Huns.

Therefore, no matter from which point of view, the Huns will spare no effort to destroy Cloud City.
