If it is said that with seven times the strength of the Dark Corps as the Central Corps, even if you don't use cannon fodder tactics, you can still take the position of the Central Corps and eat more than half of the Central Corps. It's just that it's hard to say how much it will cost, and Hei Yuehan estimates that it will have to sacrifice at least two billion troops to achieve such a strategic goal.

The forces of both sides are very limited, and no one will waste their forces on useless purposes. Cannon fodder tactics were not used, and the casualties were at least two billion. But once cannon fodder tactics are used, as long as the central corps cannot retreat, it can only fight with cannon fodder, no matter how it is calculated, it is to use cannon fodder to take advantage.

The two sides fight for cannon fodder, and the Xuanwu Legion can't fight, even if it's fully prepared, it can't be fight, and the number is too far behind. With the teleportation array as the center of the circle and 350,000 kilometers as the radius, the circumference of this circle will be 2 million kilometers, and the battle will be fought on a front of 2 million kilometers almost at the same time, even if the Xuanwu Legion is fully prepared, there are hundreds of billions of puppets, but on average, how many puppets are there on each kilometer?

There are not many Xuanwu Legions, but it doesn't mean that there are not many cannon fodder skeletons of the Dark Legion, this thing, the Dark Legion has already begun to prepare, so, in terms of quantity, at least it is more than a hundred times the puppet of the Xuanwu Legion, and such a hundred times the number of confrontations, even if the combat effectiveness of the cannon fodder skeletons is a little weaker, but as soon as this number is too much, the puppets of the Xuanwu Legion will not be enough.

Sun Mingyue looked at the situation of the battlefield, from the moment he made contact, the battle never stopped, the attack light of the Dao Immortal Magic Divine Technique within the entire range of millions of kilometers, the large-scale explosion, the entire earth was shaken, such a big battlefield. The speed of the puppet's loss is extremely amazing, even if there is a large amount of replenishment, the speed of replenishment cannot keep up with the speed of consumption, as far as it is estimated, I am afraid that it will be less than three days. The puppets will have to be completely consumed, and when the time comes, it will be up to the soldiers of the Xuanwu Legion to take it on their own.

The battle of retreat is now the fifth day, and although there have been no casualties on both sides, anyone with a discerning eye knows that the real fierce battle has not yet begun? Han Tiefang and Sun Mingyue have already reached a consensus. The retreat time of the southern and northern corps is fifteen days, and it will take at least two days to move from the main planet of 417 to the two main planets of the Great Army to launch a decent offensive. In order for the southern and northern corps to retreat without losses, they would have to stay here for at least thirteen to fourteen days, thirteen days is the minimum, and in just thirteen days, the two major corps would have to pay at least more than 50 million casualties. Therefore, some insurance plans are up to 14 to 15 days.

This also involves a cost-effective problem, in a sense, once the Central Corps casualties are too large. It is better to abandon the position and retreat, so that although it is a little sorry for the southern and northern corps, it is worth it in terms of losses. For example. Ten days later, the Central Army lost 100 million per day, so it would be better to abandon its position and retreat, and even if the Dark Army turned to attack the Southern and Northern Corps to prevent them from retreating, these two legions had already retreated because most of their forces. Even if a considerable part of the loss remains, it is not too much. Therefore. As far as Han Tiefang and Sun Mingyue are concerned, their battle must last more than ten days. As for the ten days later, it depends on the situation, and once the casualties are too large, it will be necessary to retreat.

Han Tiefang will calculate this number, and they will also calculate it for Hei Yuehan. "Judging by the current course of the battle, their cannon fodder troops can only support until tomorrow, and after tomorrow they will have to go into battle in person. And our army is not moving for the time being, let our cannon fodder troops consume their strength first, but we must send flexible and mobile troops to join the attack, so that their consumption is even greater. After two days, they are almost exhausted, then we will attack with all our might, and they will have to die here for more than ten days in order to protect the retreating forces in the south and north, so I estimate that even if their casualties are great, they will have to stay here for eleven days. From the twelfth day onwards, if their casualties were too great, they would retreat until the fifteenth day, or the sixteenth day. Therefore, from the twelfth day, we will slow down the intensity of the attack, so that they will not be willing to retreat, and if they do not retreat, they will have to pay a great price, as long as this is the only way to annihilate their main forces to the greatest extent. As for whether they can be wiped out, it depends on Lao Kong's ability. ”

For Black Moon Han's order, the commanders of the Dark Legion at all levels have already understood that this battle is the most comfortable battle, if you don't fight well, hehe, just wait to be punished.

From the beginning of the seventh day, the soldiers in front of the first line of defense of the Xuanwu Legion felt a heavy pressure, and the overwhelming cannon fodder skeletons poured over, and there were no puppets in front of them, so they could only fight on their own. What else can I do? One formation after another, countless offensive immortal techniques bombarded over, what thunder hell thousands of miles, what fire and earth flames, what thousands of miles of angry seas, etc., as soon as these attacks came out, they attacked tens of thousands of square kilometers, and powerful attacks naturally bombarded a large number of cannon fodder skeletons into slag.

It's just that although the results are outstanding, the consumption makes everyone turn a face into a bitter melon. A large-scale attack of tens of thousands of square kilometers of immortal magic bombarded down, naturally bombarding hundreds of millions of cannon fodder skeletons. However, the immortal technique of such a large-scale attack consumes at least about five percent of the true yuan of the array warriors, that is to say, if you don't rest, you have to consume all the true yuan of the whole body if you attack twenty times in a row. Twenty times later? People are tired like a dead dog, what can they use to withstand the enemy's attack? If you don't fight like this, countless cannon fodder skeletons will attack the defense line, and then it will be hand-to-hand combat, do you really think that you will be able to defeat ten thousand with one enemy? What are you kidding, is this possible?

There is no true yuan, you can only take pills, now is the time of fierce battle, wait for you to meditate and slowly recover the true yuan, then this battle is still a fart, there is no need to fight at all. Therefore, as soon as the soldiers on the front line saw that their true yuan was not enough, they immediately took the pill to restore the true yuan, and continued to fight after the recovery was over, they could only use this method, and they had no other way.

In such a battle, the soldiers of the Xuanwu Legion could only take pills constantly. Although the alchemy of the Yanhuang clan is unparalleled in the world, and the elsipelas of countless pills are very small, and the amount of true yuan is also very large, however, if anyone takes too many pills in a short period of time, they will inevitably develop resistance, and the effect that the pills can play will become worse and worse, I am afraid that if they don't wait for two or three days, the pills will be useless.

Not only that, although the Seventh Army had stockpiled a large number of pills during this time, but, after all, a large part of the countless battles before had to be consumed, and a considerable part had to be kept for later use, after all, now everyone knows that they have to run back to the central star field, and if they don't leave some pills to defend themselves, when they get to the universe, you have to wait for death. One of the biggest weaknesses is the limited number of pills.

However, the number of spirit herb elixirs that the Seventh Group Army has collected over the years is limited, and some of the spirit herb elixirs are used to refine other types of elixirs, and it is impossible to use all of them to refine the elixirs, so it would be good to have thirty elixirs that are really distributed to each person. And how long can thirty elixirs last? If you don't rest and don't replace, I'm afraid that you won't be able to support it for even a day, because this battle is endless, and it won't stop at all.

Insufficient troops is the biggest Achilles' heel, if there are sufficient troops, the soldiers on the front line are replaced, so that everyone takes turns to recover, and the time that can be supported will be much longer, but to defend a front of 2 million kilometers, only 3 billion troops, there is not much reserve at all, in the first line of defense, Sun Mingyue mobilized 90% of the strength of the first army, about 800 million, which is already the least, and the second and third lines of defense, at least 800 million troops must be left to defend, therefore, only about 1.4 billion as reserves, and 500 million cannot be moved in any case, and they are specially used to fight fires when the enemy breaks through the defense line, so, can be used for rotation is only about 900 million troops, in this way, these 900 million reserves plus the first line of defense of 800 million, 1.7 billion troops to last a few days, is definitely enough.

Of course, when things are urgent, you can also let the first line of defense retreat and replace the second line of defense, so that it can also support for a while longer. However, no matter what you do, if such a battle lasts for two or three days, the entire Central Corps will definitely have to lie down tired, and even if you don't die of exhaustion, your combat effectiveness will be greatly reduced.

"This is Black Moon Han's trick. "Shi Qingya saw through it at first sight, the opponent used cannon fodder skeletons to consume the strength of the Xuanwu Legion, once the strength of the Xuanwu Legion was almost consumed, and then it was time to attack in full force, even if the Dark Legion could not break through the defense line, the casualties of the Xuanwu Legion would be very miserable.

Sun Mingyue smiled bitterly and said: "He is a yang conspiracy, but we know what to do, we don't have to fight like this, we are now here to fight with them, no matter how big the casualties are, we have to withstand them, otherwise, our southern and northern corps will have to finish off more than half of the troops." Shi Qingya was speechless, there was no other way to think about the situation, and he could only fight with the enemy.

The really most tragic battle was from the ninth day, a large number of dark legion soldiers began to join the battle, countless offensive magic weapons bombarded over, white bone flying locust arrows, black clouds descended from the sky, yin and yang god fire angry dragon killing, sky swallowing divine beast roar, etc., the power of these magic techniques is absolutely terrifying, at least not under the attack of the Xuanwu Legion, such a powerful attack divine art, the Xuanwu Legion has no other way to think about it except for using the power of its own formation to defend, as for retreating, there are three lines of defense, where can it retreat?

Boom, the three powerful Yin Yang Divine Fire Dragons blasted through a 10,000-mile torrent array, and most of the 100,000 soldiers in the formation were spraying blood from their mouths, one by one, their spirits were broken, and they were all attacked by powerful energy, and they were naturally seriously injured. Then, under the strong attack, a large number of warriors were strangled into ashes by the powerful Yin Yang Divine Dragon Dragon, and a little bit of warriors were burned into ashes and scattered to the earth, except for a few warriors who were able to escape, the others were killed under the strong attack of the enemy.
