Fang Tiehai said: "Third brother, it's better to take the second division with me, I think that the strength of nine brigades should be enough." "No, Tiehai, you have to stay, your task is very heavy, there is a task that you must do, so you must not move." "Oh, third brother, what important task has been entrusted to me?" "When the time comes, you will know the way, and I think you will be very interested in this task." Sun Tiejian specially sold a pass, so that Fang Tiehai really wanted to beat him.

Stick to one place, and then break into the enemy's rear, disrupt the enemy's supply line, this is the essence of guerrilla warfare, therefore, hitting the enemy's rear is a matter of necessity, but it is a pity that the strength of the Yanhuang clan is still too weak, if there are five divisions of troops, Sun Tiejian is sure enough to turn the rear of the Tianhu Army upside down, however, he only has nineteen brigades in his hands, and he has to leave half of it to defend the Xuanwu fortress, so the troops that can be dispatched are at most only one division's troops, and so many troops must be sent to have a commander-in-chief, you can't turn your troops into a plate of scattered sand, so this commander-in-chief still has to be sent, so who to send?

Several giants of the coalition army, Sun Tiejian wants to sit in the Xuanwu Fortress and can't move, even if Sun Tiejian wants to go, others won't let them go, if something goes wrong, then the fun will be great, so Sun Tiejian was the first to be excluded. Fang Tiehai was qualified to go, but he had another task for him, so he couldn't go. As for the others, such as Zhang Zeshan and others, they are all separated, and the rest are afraid that they will not be able to control the overall situation.

Guan Tiebing said: "Third brother, let's go with me." "Some people's eyes lit up, yes, and there are iron soldiers. Although Guan Tiebing is not as famous as Sun Tiejian, just by virtue of the fact that Han Wenzheng, a soldier, sent him as a commander and commanded the army against the Temple of Light, he knew the strength of this master, and it was absolutely right to send him.

Sun Tiejian smiled and said: "Okay, iron soldier, the task of guerrilla warfare behind enemy lines will be handed over to you, pay attention, you must not rush forward because of greed for merit." "I understand, greed is written to be poor, and my father taught us this a long time ago. "Then you will take the first division, and the second division will stay to defend the Xuanwu fortress, is there a problem?" "Third brother, it's good." "Guan Tiebing did not refuse, he is the deputy commander of the first division, the first division can be said to be his own descendant troops, and it is of course much easier to command his descendant troops to fight, so he has no reason to refuse.

This is how the matter of guerrilla operations behind enemy lines was decided. Sun Tiejian asked, "Tie Hui, do you have any measures to improve the Xuanwu Fortress?" "Yes, third brother, through today's battle, our Academy of Sciences has decided to improve the fortress from three aspects after discussion. "What about the three areas? ”

Yang Tiehui said: "The first aspect is, of course, the issue of energy reserves. Whether we are defending or attacking, we need to consume a lot of energy, and although our current energy reserves are a lot, they cannot support a long-term big war, so in order to strengthen our energy reserves, we plan to build a large number of hydrogen and oxygen generators in a short period of time, and further research on more powerful electric motors, so that we can provide more powerful energy in a short time. "Energy is the most important thing, and if you don't have enough energy, you can't fight, so that's how it should be. All agreed.

Yang Tiehui smiled and said: "Don't praise it first, this is something that everyone has to contribute, if it is only relying on hundreds of thousands of people in our Academy of Sciences to make hydrogen and oxygen generators, then we can't make much, so in the next period of time, everyone has to do it." "This is a fact, if you only rely on those people from the Academy of Sciences to make hydrogen and oxygen generators by refining the method, it is indeed impossible to make much in a year's time, and you still need to rely on all the members of the Yanhuang Clan.

Fang Tiehai smiled: "Dean, you can rest assured, we may not be able to help with other things, but we can help with simple things like refining weapons, as long as you give an order, we will all be dispatched." "Everyone is shocked, isn't it just a simple refining weapon? Refining is the basic skill of the Yanhuang Clan's warriors, even if they are not refined, they can be regarded as proficient, not to mention that the hydrogen and oxygen generator is not a high-end thing, it is easy to get it.

Yang Tiehui said: "In addition to refining a large number of hydrogen and oxygen generators, we also need to add a large number of storage arrays and gathering arrays to the fortress to increase our energy reserves, in addition, we are preparing to build a number of anti-five elements gathering yuan arrays, hoping to convert the enemy's offensive energy into our energy reserves, so that we can fight stronger and stronger, but in terms of materials, it is not enough, and we still need to send people to other planets to mine some." "Of course that's a good thing, but as for the manpower problem, is that a problem?

Sun Tiejian said: "Tie Hui, according to your calculations, how effective is the Anti-Five Elements Gathering Yuan Great Array?" "If my calculation is not wrong, after the Anti-Five Elements Gathering Yuan Great Array is fully activated, it should be able to absorb the energy of a salvo of Star-class battleships of one front of the enemy's army." "That's good, whatever materials you want, the third brother will help you get them, as long as you make these formations successful." ”

Yang Tiehui continued: "The second aspect, we are studying a new formation, but this new formation is not so easy to study successfully, if the second brother is here, with the second brother's attainments in the formation, it should be able to study successfully within a few decades, as for me, there is no more than a hundred years of time, it is a fantasy, but as long as the formation research is successful, then our fortress can be regarded as impregnable, absolutely indestructible." "What kind of formation, is it so powerful?" For the formation, all the Yanhuang people are no strangers, but they can't imagine that any formation will be so strong even if they want to break their heads.

Yang Tiehui said: "From the theory of defense, it is the most stupid way to use energy to defend energy, but we can only use such a defense mode at present, because our strength has not reached this step, if our strength is reached, then we no longer have to worry about the enemy's main artillery." "What kind of formation is it, Dean, you're too good at selling off, say it quickly." "Some of the anxious people are going to curse.

Yang Tiehui said: "The truly invincible defense is space. "Wow, Dean, you are also too talented, such a formation actually makes you think that you are really a genius. Everyone exclaimed, even Sun Tiejian's eyes lit up, he reached out and patted Yang Tiehui's shoulder and said with a smile: "Okay, Tiehui, you can rest assured to study, no matter what you want, we will support you, even if you search the whole universe, we will help you find it, the Academy of Sciences is not enough manpower to add more, as long as you succeed in research, then we will definitely not have to worry about defense in the future." ”

What is the strongest defense, is it the force field cover of the fortress of the Heavenly Tiger Empire? Is it the Xuanwu Great Array of the Xuanwu Fortress Group? Or is it some other defense facility? The answer is all wrong, the strongest defense is space, and space is the strongest ultimate defense in the universe.

The range of the main gun of the Starship-class battleship is 10 million kilometers, the range of the Universe-class battleship is also 10 million kilometers, and the range of the fortress of the Heavenly Tiger Empire is 12 million kilometers, which exceeds this range, even if the main gun is hit, it will basically not hurt a piece of paint of the battleship, so the real strongest defense is space.

Of course, the enemy will not always fire outside the firing range, and the enemy is not stupid, but what if the space can be folded? On the surface, the distance between the two warships is only 3 million kilometers, so the main guns can bombard more than enough, and they can also annihilate the enemy's warships in one fell swoop, but if they encounter space folding, it is a different matter.

The so-called space folding is to bend the space, so that on the surface it seems that there is only 100,000 kilometers of space, but the actual distance has reached 10 million kilometers, so that although the distance between the two is only 3 million kilometers, the actual distance has reached 12.9 million kilometers, which is beyond the range of the main gun, so on the surface, it can be hit, but in fact, it is far beyond the range, therefore, the enemy's main gun is only hitting the air.

Space folding, of course, is easy to say, but if you really want to do it, it is definitely not something that a group of cultivation rookies with only sixteenth or seventeenth level strength can use, that is the ability that only Da Luo Jin Immortal has, and even Da Luo Jin Xian, who is a little less cultivated, can't use space folding, only Da Luo Jin Xian, who has a high level of cultivation and has a very high achievement in the way of space, can use it. Therefore, it is basically impossible for space to fold in the human world.

Those who are low in cultivation are not completely impossible, but with the help of the formation, the power of the formation can have such power, but if you want to arrange the space folding formation, the difficulty is not ordinary, there are not too many requirements in terms of materials, the difficulty lies in the lack of advanced formation attainments, no deep understanding of space, that is not to think about it, therefore, although Yang Tiehui thought of this method, but he was not sure that he would be able to arrange the space folding array, I am afraid that it is the strength of all the staff of the Yan Huang Academy of Sciences, and the research may not be able to succeed for more than a hundred years, which is beyond their ability。

Of course, Sun Tiejian and the others also understood the principle, but they never thought of using the space folding array to defend, because it was almost impossible to deploy the space folding array at this stage, but Yang Tiehui had no other way to propose the use of the space folding array, and made up his mind to invest in the strength of the Yanhuang Clan's Academy to study the space folding array, as for whether it succeeded or not, he had no way to pack the ticket, so he also needed the support of Sun Tiejian and others.

If you devote yourself to the study of the space folding array, then the research in other directions will naturally slow down, or even stop completely, this is not a joke, the main gun, the protective cover, the further design of the fortress, etc., these will take time to study, if you stop, then the strength of the Yanhuang clan will stagnate, backwardness means being beaten, therefore, fully devoting yourself to the study of the space folding array is also a more risky action, which is also understood by everyone.

Sun Tiejian said: "I have decided to fully support Tie Hui and them in their research on the Space Folding Array, however, the stakes are very high, what do you think? Think about it slowly, and we will vote again tomorrow." Tie Hui, now you can talk about your third aspect. ”
