Refining is a systematic project, the number of formations is as large as a cow's hair, and there are also a lot of refining techniques, in a word, even if you are a genius of refining, if you want to master all the refining methods, it will take more than 10,000 years. However, the refining weapon can be split, all the formations are basically composed of basic formations, a huge formation, the basic array accounts for the vast majority, as long as these basic formations are solved, the others will be much easier. It is not difficult to refine some basic arrays, even people who have no experience in refining weapons, as long as they have a year or two of training, they can arrange the basic arrays, and then teach them some simple refining knowledge, they can use liquefied metal to refine the basic array parts that meet the requirements. In this way, you need a trillion parts for a battle city, but I have 100 billion people, and I refine a few every day when I have time.

The fourth step is assembly. All the parts are recycled and assembled, and then the guò system is debugged, and it can be officially put into use, and a battle city is considered complete. However, this last step requires professionals, and it is impossible to participate in this final step without a refining master or above. And this one is a reality that can no longer be changed, therefore, the reason why all the major Holy Land legions are highly valued by refining masters is precisely because of this, without refining masters, it means that you can't refine the battle city.

It is undeniable that most of the battle cities refined in this way meet the requirements, but, after all, this is only a battle city refined from ordinary materials, and it is naturally not ideal in terms of attack and defense. In addition, the people who refine all kinds of basic array parts are rookies, and the power of this formation will naturally be affected. So. Neither in terms of attack nor defense can meet the requirements of level 36 and 35.

For both of these aspects. Yang Tiehui also had no solution. In the end, the only way is manpower, and the use of manpower to strengthen. If hundreds of thousands or millions of soldiers are mobilized to arrange formations in the battle city, and then the arranged formations are superimposed with the formations of the battle city, in this way, the attack and defense power of the battle city can be improved, so that the offensive and defensive capabilities of the battle city can meet the requirements, and even. It is also possible to exceed, because, in addition to the quality, sometimes in addition to the quality of the array, but also the quantity, the mobilization of 500,000 people and the mobilization of 5 million people are two concepts.

To deploy the formation with people, we must pay more attention to the cooperation between people, even if it is a well-trained army, sometimes it will be chaotic, therefore. Yang Tiehui borrowed from the array battleship of the Winged Girl Clan back then, and fixed the position of the formation in the battle city. As long as people are in the formation, you can enter the true element, it works, and the number of people in the formation is divided into several levels, the number of people can reach 10 million at most, and then a level for every million people, so that when there are few people, there are few people, and when there are many people, there is a way to arrange the formation, which perfectly solves all the problems.

After the successful study of the battle city, he shined on the battlefield of the river system, beating the Angel Protoss and the Dark Protoss to the ground, causing the two clans to suffer countless hardships. However, these two clans are not the masters who will only be beaten and will not fight back, your Yanhuang clan will study the battle city, they will also, and, after having a successful model, it will be much easier for them to study, and finally on a river system, they used a large number of warrior lives to consume all the energy of a war city, and then, the battle city was sunk, and then captured some extremely important parts and other things, although the Yanhuang clan was deeply dissatisfied with this, but there was no way.

After the two clans captured the battle city of the Yanhuang tribe, after thousands of years of research, they finally researched their war tools suitable for fighting on the battlefield of the river system. The Angel Protoss is called the Angel Divine Light Ship, and the Dark Protoss is called the Dark Temple, and the power is not much different.

In the river wars one after another, the participating troops put forward more requirements for the battle city, for example, whether the offensive class can improve the stronger attack power, and the defense class can enhance the defense power, etc., in a word, the battle city is moving towards more practical and concrete.

Through guò research, Yang Tiehui and others were so tired that they didn't have half a life, and finally created a series of battle cities, and the entire battle city series includes five categories: attack battle city, defensive battle city, raid battle city, life battle city, and base battle city. Attacking the battle city, is to weaken other aspects, but strengthen the attack aspect, the biggest feature of this kind of war city is strong mobility, strong attack power, pay attention to one blow to go, one close to the fight, just like an assassin, hit until you have no temper.

Defensive battle city, but take the defensive route, greatly strengthen the defense, to put it bluntly, is to do the life of the shield, in order to maximize the defense power, where the enemy attacks, they believe where to block, protect the other cities behind, under normal circumstances, the defense of the city is no way to break through any attack.

Raid the battle city, this type is to play a surprise role, specially used for sneak attacks, and the enemy has been taken down before the enemy can react. The application of a large number of formations such as the Hidden Heaven Array makes them ghosts in the dark, elusive and unguardable.

The life battle city is for healing, and the most important thing is, of course, to heal people, including the maintenance of the battle city. Both the Angel Protoss and the Dark Protoss have a lot of very strange things, and the warriors who are injured under those strange attacks cannot be treated by ordinary elixirs, and at this time, the Life Battle City plays the most important role.

Base Battle City. Among the six series, the base battle city is the largest, on the one hand, it is the logistics base of all the battle cities, including the production base of the battle city. On the other hand, it has a special ability, that is, it can land on the enemy's position, and can turn the liquefied metal of the shell into a formation talisman to communicate with the underground spiritual veins, so that it can borrow the role of the underground spiritual veins, which is equivalent to becoming a huge base that can be fully put into use in just one hour, which is a great effect on warfare.

Different battle cities have different manpower and material resources, but each battle city is very powerful. And the continuous improvement of the battle city over the past tens of thousands of years has gradually replaced the warship and become the standard equipment of the major holy land legions of the Yanhuang Clan. Of course. The battle city with standard equipment is naturally much stronger than the one that is improvised on the battlefield of the river system. Moreover. There are also many more features. And this kind of heavy weapons used exclusively by monks, and also used by powerful monks, each of them has a very terrifying power, far stronger than ordinary warships. It can be said that there is absolutely no problem for a battle city to single-handedly take on a fleet.

Fifty battle cities are enough to accommodate five billion troops, and these five billion troops are the main attack force at present, if the opposing forces are evenly distributed among the three hundred main planets. Each main planet is only a billion troops, plus they have to be evenly distributed among hundreds of bases, each base is only millions to tens of millions of troops, if you can concentrate on attacking one base, with the powerful attack power of the battle city, it is naturally a sure win. But the premise is that the opposing forces will willingly let you attack so easily?

At the highest-level meeting, Zhou Hongyuan said: "Brothers, now that we have preliminarily owned the battle city, almost sixty years have passed. The 100-year exercise period has left us less than 40 years. It's time for us to attack, otherwise we'll have to throw in the towel. However, we have not yet fully decided on the specific plan of attack, and there are certain differences between me and the commander-in-chief, so I hope that everyone will come together to think of a way to do this enlarged meeting. ”

Zhu Tiezhen asked: "Brother Zhou, what are the plans you have preliminarily formulated? Can you tell us about them and let us refer to them?" I worked with the Commander-in-Chief on four strategic options. The first scenario is a decisive battle in space, which we call the decisive battle in space. The core part of this plan is that we concentrate all the battle cities, and then, set out the chariots and horses to attack, lure out the battle city troops of the opposing forces, and the two sides will fight a decisive battle in space, and use all the methods to destroy the war cities of the opposing forces, as long as we can destroy the war cities of the opposing forces, then we will take advantage of mobility, and when the time comes, it will be easy to fight or leave. The disadvantage of this plan is that we only have the strength to fight, and once we lose the decisive battle, then we don't have to fight this battle anymore. ”

For this plan, everyone is silent, it is too dangerous, if you win, you have a great chance of winning, but if you lose, you have no power to turn over, even if it is a draw, I am afraid that it will be difficult to have any chance of winning.

"The second option, the guerrilla program. The core of this plan is that we divide the battle city into multiple routes, with feints and main attacks, with varying forces, and divide our troops to attack different main planets, so that the opposing forces cannot distinguish the direction of our main attack, and then, step by step, eat the bases on each of their main planets and consume their troops. The initiative of this plan lies with us, and it is not difficult for us to fight or leave, and the greatest advantage of this plan is that our army's losses are not large, which is convenient for protracted warfare. The disadvantage is that the results are relatively slow, and the support of the opposing forces is rapid, so it is easy for us to obtain results, but it is difficult to expand them. ”

In a sense, this plan is the best plan for the weak to defeat the strong, but the disadvantage is that it takes a lot of time, if there is countless time, it is natural to adopt this plan, but there is only forty years, time, can not be wasted.

"The third option, a little attack, and then a protracted war, a war of attrition. The core is that we concentrate all our forces, take a main planet by surprise, and then, eliminate all the enemies on the main planet, and then fight the opposing forces on this main planet. After we have a main planet, plus the teleportation array we have built over the years, we can basically concentrate most of the troops, so that we are almost equal to the counter forces in terms of reinforcement, and we already have the ability to fight a war. It's just that after such a battle, I'm afraid that both of us will fight to the end and lose both. ”

Han Tiefang said: "I am still worried about this plan, that is, if the confrontation forces abandon this main planet and do not fight us, then our plan will be completely abandoned, and according to my estimate, the probability that the chief instructor will take what I just said is more than ninety percent." Once we divide our forces to attack the other main planets, they may attack the main planets we occupy, and at that point, our army will be in a position of defeat and even more trouble. Therefore, I am not in favor of this option. (To be continued......)
