Demon Realm, the Northern Frontier.

In the simple shed, Song Chengyin was holding something like a piece of meat in one hand and feasting, and in the other hand holding something like a marker pen to draw in circles on a map, and next to her sat a few demons wearing armor and werewolves, but unlike their somewhat hideous appearance, at this time their eyes were moving intently with the tip of the pen, looking at that look, I am afraid that even if someone puts a knife on their necks, they will not know it.

Calculating the time, it has been half a month since the five directors of the human race came to the Demon Realm.

In the past half a month, as the allied forces of the east, west and south regions approached, the defense line in the northern region continued to shrink, giving way to one city after another, so that later the five division directors had to move from the safe rear to the front line to take command. Although there was no big loss in this part of Song Chengyin's responsibility, the news from the other four defense lines was not very optimistic.

At first, these demon soldiers who had been bloody on the battlefield for many years were naturally unable to accept the command of humans. In their opinion, the human race is weak and chaotic, but since these people were personally found by His Royal Highness the Crown Prince, they also suppressed their tempers as much as possible. But after half a month of running-in, these soldiers finally understood that it was entirely possible for the weakness of human beings to be compensated for by their wisdom, and the original prejudice against human beings also disappeared with one battle after another.

In fact, after entering the Demon Realm for the first time, Song Chengyin didn't get used to it for several days, because there were too many powerful auras here. She had thought that the demons were a polarized race, because the King of Heaven was too strong to assist the Shield of Justice in its mission, and the monsters that were generally regarded as targets for purging were too weak in comparison. But it wasn't until she herself really entered the demon realm that she realized that even if she was pulled out of the demon army, she might not be much worse than the four horses.

But in the same way, such a powerful has long been the general disguised pursuit of power by the demons, so that they are sometimes really stupid and cute.

And because of this, the demons will only study how to have a more shocking attack power, but there is little research on things like enchantments used for defense, which just allows Song Chengyin and others to take advantage of them to set up enchantments in various dangerous places, and the result is that the advance speed of the alliance army is completely suppressed, which gives the northern region a barely acceptable respite, so that it can be used to organize retreats and deliver materials to the front line.

"Wait, Director Song, what does this mean, aren't we going to help Xiacheng? That city lord is my brother-in-law, can't you see death and not save it." Watching Song Chengyin's pen tip swipe across the map, a large man with several scars on his face next to her hurriedly interrupted her, looking very anxious.

There are more than a dozen main cities on the Northern Frontier, guarding dozens of major roads leading to the interior of the Northern Regions, and these main cities, which are large enough to accommodate hundreds of millions of inhabitants, each have a dozen auxiliary cities. Now Song Chengyin is in an auxiliary city, and the Xia City in the mouth of the demon clan is the closest auxiliary city to here.

casually pulled a piece of animal skin and wiped his hands, Song Chengyin patted the demon clan's shoulder, and said: "Don't worry, now you can't give up the city in exchange for a chance to retreat like before, that is to say, your brother-in-law I will definitely find a way to save it." I took a look at the map, and the terrain of Xiacheng is difficult to attack and easy to defend, and this team from the Three Domains will definitely have to fight for a while. During this time, we did not have to go directly to rescue them, but went straight to the base camp of the other side, cut off their supplies, and forced them to retreat and return. And at this time, if the recuperated Xiacheng army suddenly pursues and flanks them with us, they can completely eat this squad in a place where the opponent's main whip is out of reach. ”

After saying that, Song Chengyin pressed the map onto the table, and his small hand pressed the mark representing the enemy.

As she continued to go deeper, she also discovered another lovely thing about the demons: the armies of the demons would never disperse to form any tactics, because in their opinion, the absolute power competition had already decided everything. Therefore, no matter what kind of battle, even if it is just to fight for a small hill, the two armies of the confrontation often do their best. And for a major battle such as a siege, the attacker will definitely do its best.

When he said that he was going to eat the other party, Song Chengyin's hand couldn't help shaking. Under the influence of the vast territory of the Demon Race and the astonishing number base, the so-called "squad" of the Demon Race is by no means a small formation, it is an army composed of hundreds of thousands of Demon warriors at every turn.

Several demon generals in the camp thought carefully for a long time after hearing this, and finally raised their heads one by one and looked at Song Chengyin with admiration, the eyes that seemed to be flashing little stars appeared on these big men with scars and fierce gods, which really provoked Song Chengyin couldn't help laughing.

"This time is different from the previous ones, this is the first time we have organized a counterattack, and it will have a big impact. So this time I will personally command the army," Song Chengyin said as he looked at the map several times and discussed some details with the generals repeatedly.

Due to the limitations of her own strength, Song Chengyin has always been in charge of the security zone as a co-ordination, even if she needs to constantly explain tactics repeatedly to ensure that there will be no mistakes in the operation, she is still the same. But those were just things like directing how to evacuate, where to set up barriers, and for this first counterattack battle, she had to personally command it to ensure success, even if she risked her life.

According to previous intelligence from other regions, it is very likely that the Three-Regions Alliance is about to launch a large-scale attack, and if the morale of the Northern Region Army is not boosted by a victory in a battle before this, the shadow of defeat will completely accompany the Northern Army. Moreover, in order to preserve their strength, they chose to retreat as much as possible to avoid fighting, which has made many people lose confidence.

What's more, with the continuous contraction of half a month, the Northern Territory has lost nearly one-third. The Northern Regions are certainly strong, but they cannot sit idly by, and once the strategy of preserving strength becomes a policy to shake the national strength, then everything will be powerless.

Until everyone dispersed, Song Chengyin, who was constantly pondering the current situation in the Northern Regions, still did not rest. In the Demon Realm, there is no distinction between day and night, and the entire sky is always chaotic. The only thing used to determine time here is the periodic change of natural magic in the air, and humans who are not sensitive to this may not have slept for several days if they are not careful.

"How long has it been since I've slept......" Scratching his somewhat unkempt hair, Song Chengyin's slightly frowning gaze fell on the map again, "It's about to be a battle, and now is not the time to think about relaxing." ”

Just when Song Chengyin was worried about her increasingly lazy brain cells, a small head suddenly poked into outside the long curtain of the camp, and a slightly timid immature voice came into her ears: "Sister Si, it's time to rest." ”
