The other 'doors' don't need Liu Ye to 'worry' too much, and the food department's 'doors' are enough for the next five years.

As for the 'door' of the weapons department, because of the influence of the 'door' of the metallurgical and iron steel department, the development was a little slower, of course, this was expected by Liu Ye in advance, and he didn't care.

There are other departments such as the textile and garment department, the power department and the coal department, all of which have developed in an orderly manner without any thorny problems.

The only headache for Liu Ye now is the most serious problem in the two cities - population shortage.

At present, the population resources of the two cities have been used to the limit by Liu Ye, but the demand for labor in various industries is still very large, but this demand cannot be met at all.

The surrounding tribal groups were all conquered by Liu Ye, and most of the personnel were grouped into two cities, but it was also a drop in the bucket, and it was difficult to solve the fundamental problem.

Because of the lack of population, the technical level of production efficiency in many industries has been reached, but because of the lack of personnel, it cannot be further increased, and the production can only be reduced.

Liu Ye and Nan Tiancheng discussed that in order to meet the population needs of the current two cities, at least three more cities must be increased.

The only way to solve the population problem is to turn to other cities for help.

But population is the lifeblood of a city, how can other cities give people away, even borrowing a little.

In other words, if you want to get a large number of people in a short period of time, you can only attack other cities.

Although wars often occur in the wasteland, inter-city conquests rarely occur.

Everyone understands that it is okay to fight between man and man or man and beast, but when it comes to city to city, it is not so simple.

It is not easy to establish every city, and after a battle, it will greatly deplete its own strength. Of course, the victorious side will get a lot of resources and develop rapidly.

Therefore, in order to prevent some cities from developing rapidly by plundering other cities, there is an unwritten rule among the major cities of the wasteland that it is absolutely forbidden to attack other cities for no reason. Otherwise, it will be regarded as a challenge to the entire wasteland and will be sanctioned by the entire wasteland.

A few days ago, Liu Ye captured Haiwei City, one is because Haiwei City did provoke first, and it is understandable that the capital city attacked Haiwei City. The second reason is that after the capital occupied Haiwei City, it did not do anything to other cities, and still supplied salt to various cities. The third is that the strength of the capital is very strong, and ordinary cities dare not say anything.

However, if the capital city starts to conquer other cities, it will inevitably cause panic in the wasteland, and at that time, it may cause a collective attack on the entire wasteland.

This is also the reason why Liu Ye did not continue to attack other cities after occupying Haiwei City, but only tried his best to develop himself.

Just because the capital is the first city in the wasteland doesn't mean that it can resist the combined attack of all the cities in the wasteland.

But now it can't be done, the development of the capital city and Haiwei City has reached the limit, and if the population needs is not provided, the growth rate of the capital city and Haiwei City will slow down, which Liu Ye does not want to see in any case.

With the eyes of Susha on the outside, and the pretending gods of the Mitheistic Sect to 'trick' ghosts, Liu Ye had to quickly improve his strength.

Anyway, sooner or later, the capital city will have a 'engagement' with other cities in the wasteland, and since it can't be avoided, it doesn't matter if it plays earlier.

"Liu Ye, you have finally made up your mind!"

Nan Tiancheng, who was recruited by Liu Ye, looked surprised, but they didn't expect Liu Ye to make a decision at this time.

"Not bad! It's better to come late than early! Now the development of the capital city has been very rapid, and its military strength far exceeds that of other cities! This is the best time to attack! Liu Ye nodded and decided.

"At this time? It's winter! Many of our weapons aren't as powerful as they should be, and now isn't the best time to attack! Bei Nanfu shook his head and said.

Liu Ye smiled confidently and said, "Hehe! It's hard to remember that you're right, although our weapons are the most powerful, the other side estimates that there are fewer weapons that can exert their power! In this way, we still have the advantage! ”

"It's a risk...... "Bei Nan Shen groaned for a while.

"Oh? Are you scared? Liu Ye asked deliberately.

"Of course not! I'm just worried that the attack will go well, the soldiers never made a sortie in winter! "I'm still a little worried.

"You have a point, but the enemy has not been attacked by other cities in the winter, and their defenses must be even more lax!" Liu Ye continued.

"Which cities did you decide to attack?" The North mourners in turn asked other questions.

"These are the three!" Liu Ye spread out the map that Tang Yueyue had drawn with his heart, pointed to the three cities on it and said.

"These three? Liu Ye, do you want to fight on three fronts? It seems that you are a drunkard who doesn't mean to drink......" Bei Nanfu looked at the three cities, which happened to be located next to the Pure Land City, and the Pure Land City became an arch guard.

"That's right! My main target this time is Pure Land City, as long as we capture him, there will be no more cities in the Southern Wasteland to stop us! Liu Ye patted the map and said.

"Are you so sure? Won't there be any other forces coming to stop us? Nan Tiancheng asked.

"Of course there is, but I'm ready! Sooner or later, they're coming, so this time I'll have a head-to-head confrontation with them! Liu Ye said resolutely.

"Alright! You are the lord of the city, I am the general! If you specify the present, I'll go all out to break it! It's just that you're going to meet all my military needs! Bei Nanfu thought for a while and made a request.

"Tell me what you want! I will definitely satisfy you with all my might! Seeing that the North Martyrdom finally agreed, Liu Ye was overjoyed.

"I want to ......," Bei Yanfu opened his mouth to say a series of demands.

"The Second Army was originally prepared for you, if you don't think it's enough, you can also pick some other people in the city and fill it in. It's just that the Eagle Bat Army and the Exocet fleet can't give you, but they can give you some cover to a certain extent! "There are many requirements for the mourning in the north, Liu Ye frowned slightly, it is impossible to 'hand' all the troops into the hands of one person.

It's not that he doesn't believe that the north will be lost, but that all the troops are in the hands of the same general, which will inevitably cause a vacancy in military strength elsewhere on the battlefield.

"That's fine! But I ask those two forces to be led by me! Bei Nanfu thought about it and said.

"There's no problem with that! The ground forces are the main force in this attack, and naturally you are the leader! ”

"Good! What is the timing of this attack, ......? Bei Nanfu asked.

"Right at the time of this wasteland gathering!" Liu Ye's eyes flashed with a strange light.

"Wasteland rally? So we didn't attend this rally? Nan Tiancheng was stunned, he didn't expect Liu Ye to choose to go out at this time.

"I didn't participate! How much do you think those things at the rally will help the current capital and Haiwei cities? We're making things so much better than they are! Liu Ye shook his head and said.

"This ...... You're right! Nan Tiancheng came to his senses at this time, and it had become a habit to participate in the wasteland rally, so he was naturally a little surprised to hear that he would not participate this year.

"The most important thing is that many of the city lords left their cities to attend the gathering during the wasteland rally. They won't come first at all, someone will attack at this time, and at that time, the defense ability of the city without the city lord will be reduced by at least half! Bei Nan mourning continued.

"Yes! As Sad Mourning said, that's why I chose to attack here! Liu Ye nodded approvingly and looked at the North Mourning.

"Liu Ye! You're very sinister! Nan Tiancheng suddenly realized.

"'Insidious'? This is called wisdom, and attacking it unpreparedness is the first rule on the battlefield! Liu Ye said with a smile.

"You're really 'sinister'!" Nan Tiancheng said again.

“***……”

……

As soon as the decision to attack the city was made, the capital city immediately became busy.

First of all, he refused the messenger who had come to invite the capital to the rally, and he left with a look full of shock and wonder, and he couldn't understand why the metropolis, which had never been absent, was absent from such an important wasteland gathering this time.

"Don't you go for such a great opportunity? Is the capital so powerful that it doesn't need to resort to the wasteland assembly? "The messenger was suspicious, and he decided to pass the news on to the lord as soon as possible.

When he found out that the messenger was coming, the capital city had already done some disguise and successfully deceived the messenger, making him think that the capital city had indeed developed, but not particularly large.

From Tang Yueyue's mouth, Liu Ye knew that the messenger not only took on the mission of delivering news, but also served as ten people who sped on the development of various cities.

The six northern cities were not strong enough to conquer the entire wasteland, but they were also unwilling to be occupied by other cities. They would rather maintain the current balance of power in the current wasteland, so that as the strength of the six northern cities grows, they can slowly eat away at the entire wasteland.

Knowing that the people who came still had such a mission, of course Liu Ye would not 'show' his true strength in front of them, not to mention that he was ready to capture other cities.

"Liu Ye! Are you sure that the Six Cities of the North will not attack you? "Nan Tiancheng and Bei Nan mourning once asked about this matter worriedly.

The combined strength of the six northern cities is very strong, and the capital city does not dare to touch its edge.
