A cold wind blew the Blue River, the great river that surrounded the Demon King City was now frozen and hard, even if the chariot was driving on it, there was no problem.

But the amazing thing is that you can still see the fish swimming under the surface of the river, and the ice is unexpectedly transparent, like smooth glass, and this wonder is also unique to the Blue River.

On the other side of the Blue River, at intervals, there are many tents, where humans are stationed, blocking all the way out of the Demon King City.

The Holy Alliance sent hundreds of thousands of troops to block the area, and even reinforcements continued to come, thickening the place.

The Demon King is not dead, and no one dares to leave without permission.

However, the hearts of these soldiers grew colder and colder with the weather.

Indeed, they were victorious, and even captured the Demon King City.

But this is still useless, judging by the damage caused by the Demon King, he is still moving around, sometimes interspersed, sometimes circling and mediating, like a mouse.

The former king, now he can only flee in the encirclement in embarrassment, which sounds funny, but from top to bottom, everyone in the Holy Alliance doesn't think it's funny.

Hundreds of thousands of people were invested, but they still couldn't catch him!

It's been a week since the Demon King City was breached, and the Demon King was seriously injured, and now is a great opportunity to get rid of the troubles forever, but all I got was the news that a team had died.

The big guys above are starting to get anxious, and one by one the professionals are as if they don't want money, and the biggest change is that those brave adults who can't usually see it have been incorporated into the most basic reconnaissance team, you know, not to mention the coalition army, which is a joint army of all kingdoms and principalities, even if it is the elite knights of the empire, they usually do not integrate the brave into the grassroots battle sequence, but will form a special operations team to break through with sharp knives.

The form has come to this point, and this is a fact that is perceived in the shadows of everyone's heart.

At this moment, in the cave, there is no fire or other lighting, and the dark vision is enough for Lu En to see things, and all the people here have dark vision.

Lu En walked over to the place where the orcs had gathered, where the orcs were nibbling on dry food.

As soon as Lu En arrived, the orcs consciously stood up: "King! ”

There was reverence and fear in their eyes, and they had originally followed the king only to survive, but after this week, all of them were convinced.

Because, a week of guerrilla, the number of orcs killed is-

Zero.

Yes, Zero, no one died, every action was 100% certain, and in a week more than two dozen reconnaissance teams were destroyed, and seven of those invincible human braves were killed.

They never thought that they and others could actually exert such power, just by obeying orders, they could burst out with such terrifying power, it turned out that the battle could still be fought like this, they were all WAAAGH before!! rushed out directly and just head-on, looking at it this way, the war was fought so hard before, purely because the chief had water in his head!

On the other side, Lu En walked up to Tyrene, the fighter who was reading.

Sensing Lu En's arrival, she first got up and saluted, and then hurriedly picked up the book: "Wang, about your theory!" I still have some questions! ”

As soon as he heard this, Lu En suddenly felt a pain in his head, but he still stiffened his head and began to explain it to Tailin.

This is the norm these days, and Tyren has been studying some of the theories that Lu En has come up with about protracted warfare in her free time, and has come to inquire from time to time.

While explaining to her, Lu En couldn't help but think back to the events of the previous week.

Because Tyren has the skill of tactical command, in order to fight, Lu En took out a little knowledge from his head that this world does not have.

After becoming the Demon King, it may be because of the change in the brain structure, he found that his memory as a human became extremely clear, and he could even recall how hard he used to walk when he first learned to walk, and the same is true of the Demon King's own memory, which may be the commonality of transcendent creatures, but it is different for Lu En!

When he discovered this, he was so excited that he almost squirted, you know! The knowledge in his head, the knowledge from that world, all came to mind! It's like a library, all the books he's read, all the teaching videos he reads in college, there's no here!

Chemical formulas, equations, and various theories aside, the most useful thing now is, of course, to talk about protracted warfare.

So he dictated the book to Tyrene, Kara, and many other orcs, and wanted them to learn it.

The orcs obviously didn't understand, and Kara looked absent-minded, and it could be seen that she understood, but she didn't care, the dragon didn't need it.

But Tai Lin, this demon fighter with tactical command skills, after listening to it, she was surprised and almost suffocated, and then, she asked a question.

"King, why are we losing?" Lu En, who was very serious, asked Tylen.

She couldn't understand that Wang's tactical concept was extremely superb! She was amazed, but why did the coalition army finally attack the Demon King City, and the major legions guarding the King City were directly defeated before they even had time to make a formation, and the king himself was besieged by the court mage group and the braves, and finally almost died, and he is still weak.

Lu En spread his hands in his heart, why, the ghost only knows why, in his memory, the unlucky devil demon king didn't do any decent resistance at all, and lived like a mallet.

But he only has memories, and he doesn't know the brain circuits of that unlucky guy, so he can only pretend to be deep and say slowly: "Why? You'll find out about this later. ”

Tyrin took a deep breath and vaguely sensed that there was some kind of particularly deep conspiracy.

“…… Yes, I see. She said tremblingly.

Seeing that the other party was bluffed, Lu Encai breathed a sigh of relief, if the other party asked to the end, then maybe it would be exposed, Tai Lin didn't have to worry, but ......

Recalling this, Lu En glanced at Kara.

The dragon maid was still so graceful and beautiful, the dragon tail was stretched out, and she was sewing clothes for Lu En with a needlework tool in her hand that she had conjured out of nowhere.

Even the Demon King had to wear clothes, but his original clothes were already in tatters, but the maid could always take out some strange tools, such as needles and threads, from under the wide skirt and sew Lu En's clothes.

As for the set he has now, it is new.

That's right, new, Kara dismantled the human officers' clothes into fabric, and then re-sewed them into clothes.

The maid did much more than that, although there was no shortage of supplies, but because they were all robbing human supplies, and the human army was known for eating, some of their military rations were moldy, even if they were good, they were as bad as, and those dry rations were only distributed for survival, and in the human empire and many kingdoms, the treatment of grassroots soldiers was unbelievably poor, and some dried meat was even prepared fifty years ago, and there was no doubt that it could stab people to death when used as weapons.

Of course, the orcs had no problem eating these, they had good teeth, but when Lu En was about to eat them, Kara was the first to disagree.

She said solemnly, as a personal maid, how could she let her master eat these? So, she dealt with it.

Lu En didn't know what she did, anyway, what was served in the end was like something in a restaurant with 8,000 yuan per capita, and it was even set on a plate and decorated with the petals of the dragon boat flower.

The dragon boat flower blooms in summer, and now the temperature is even frozen in the blue river.

At that time, Lu En couldn't help but ask, "Where did you get it from?" Magic? No, you shouldn't have any magic. ”

"This is what you should do as a maid, the master doesn't care about the work of our subordinates, your task should be something more ambitious." Kara replied with a smile.

Lu En had no choice but to give up, after all, he was still wary of Kara now, and this incident only made him more worried, this maid, does she still have hole cards? How can you still get dragon boat flowers and delicate tableware now? This world has never heard of space equipment, even in the world of magic, space technology is impossible, how did she do it?

Lu En didn't know, and he didn't want to know.

After all, the imperative is to get out, and this goal is already half accomplished.

Pulling his gaze away from Kara, he continued to walk towards the inside of the cave.

In the deepest part of the cave, it is not wet, on the contrary, it is quite dry, and a cool breeze blows, proving that the cave is not closed, but has multiple exits.

In the depths of the cave lay many sacks of burlap, stolen from the coalition forces.

Most of the pockets were filled with grain, a kind of military ration that was mixed with wheat flour and corn flour, steamed and carried with them, and tasted like sand.

Others are dried meat, salted for at least ten years, the kind that can never be gnawed with teeth, and usually this flour and dried meat are chopped up with a knife and mixed together to make porridge.

On the other side, there are also some refined military rations, sealed in glass bottles, which are eaten by humans in an emergency, and when fighting to the most urgent time, they may not be able to make a fire, nor may they have water, and they may not even have to eat the turf, so these refined military rations are left for emergency at that time, Lu En has seen it, this is filled with animal meat sealed with oil, which is also the staple food that the orcs have eaten recently, anyway, this kind of thing, humans are reluctant to eat, they grab a lot, there is no need to stay, and to be honest, this thing is not delicious, cold and greasy, still salty, far worse than the food made by Carla

The rest is some miscellaneous items, personal belongings carried by humans, ordnance, and armor and the like, which are basically useless.

"I'm almost done with everything, so it's time to break through." Lu En checked the looted materials, and his eyes lit up.

It can't be delayed any longer, and humanity will wake up from joy.
