The cold wind is blowing on the Blue River. This large river that surrounds the Demon King's City is now frozen solid, even if a chariot can drive on it, there will be no problem.

But what’s amazing is that you can still see fish swimming under the surface of the river. The ice is unexpectedly transparent, like smooth glass. This spectacle is unique to the Blue River.

On the other side of the Blue River, there are many camps at regular intervals. Human beings are stationed here, blocking all exits from the Demon King's City.

The Holy Alliance Army dispatched hundreds of thousands of troops to blockade this entire area, and even reinforcements continued to arrive, thickening the area.

The devil is not dead, and no one dares to leave without authorization.

However, the hearts of these soldiers became colder and colder like the weather.

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

But this is still useless. Judging from the damage caused by the devil, he is still moving around, sometimes weaving in and out, sometimes mediating around, just like a mouse.

The former king can only flee in embarrassment within the encirclement. It sounds funny, but from top to bottom in the Holy Alliance, no one thinks this is funny.

After investing hundreds of thousands of people, we still can't catch him!

It has been a week since the Demon King's Castle was breached, and the Demon King was seriously injured. Now is a great opportunity to eliminate future troubles forever. However, the only news we got was the death of one team after another.

The big shots above began to get anxious, and one after another professionals poured in as if they were free of charge. The biggest change was that those brave adults who were usually invisible were incorporated into the most basic investigation team. You know

, let alone an army united by kingdoms and principalities such as the Alliance Army, even the elite knights of the empire usually do not integrate brave men into grassroots combat orders, but form special operations teams to carry out sharp knife attacks.

The situation has reached this point. This is a fact that everyone is aware of in their hearts.

At this moment, there was no fire or other lighting in the cave. Dark vision was enough for Lu En to see things. Everyone here had dark vision.

Lu En walked towards the place where the orcs gathered, where they were eating dry food.

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

There was reverence and fear in their eyes. Originally they only followed this king for survival, but after this week, all of them were sincerely convinced.

Because, during a week of guerrilla warfare, the number of orcs killed was——

zero.

Yes, Zero, no one died. Every action was 100% sure. In one week, more than twenty reconnaissance teams were wiped out, and a total of seven of those arrogant human braves were killed.

They never thought that they and others could actually exert such power. Just by obeying orders, they could burst out such terrifying power. It turned out that the battle could still be fought like this. In the past, they were all WAAAGH!!

After rushing out and facing the front, I saw that the battles in the past were so difficult simply because the chief had water in his head!

On the other side, Lu En walked next to Tailin, who was reading a book.

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

Upon hearing this, Lu En suddenly felt a headache, but he still had to bite the bullet and began to explain to Tai Lin.

This has been the norm these days. Tailin has been studying some of Lu En's theories on protracted war in her free time, and comes to inquire from time to time.

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

Because Tai Lin has the skill of tactical command, Lu En pulled out some knowledge from his mind that was not available in this world in order to fight.

After becoming the Demon King, perhaps due to changes in his brain structure, he found that his memories as a human became extremely clear. He could even recall how hard he used to exert force when he first learned to walk, and the same was true for the Demon King's own memory.

, this may be a common characteristic of extraordinary creatures, but it is different for Lu En!

When he discovered this, he was so excited that he almost burst out. You know! All the knowledge in his mind, the knowledge from that world, all emerged! It was like a library. All the books he had read,

None of the instructional videos you watched when you were bored in college are available here!

Leaving aside chemical formulas, equations, and various theories, the most useful thing now is, of course, the discussion of protracted war.

So he dictated the book and told it to Tailin, Kara, and many orcs, hoping that they would learn from it.

The orcs obviously didn't understand, and Kara looked distracted. It could be seen that she understood, but she didn't care. The magic dragon had no need for this thing.

But Tailin, a demon warrior with tactical command skills, was so surprised that she almost choked after listening to it. Then, she asked a question.

"Wang, why did we lose?" Tailin asked Lu En very seriously.

She couldn't understand. The king's tactical concepts were extremely superb! She was amazed, but why did the coalition forces invade the Demon King's City in the end? The major legions guarding the king's city were directly defeated before they even had time to form a formation, and the king himself was even more so.

He was besieged by the palace mage group and the brave men, and almost died in the end. He is still very weak now.

Lu En's heart paled. Why, no one knows why, in his memory, the unlucky devil king didn't put up any decent resistance at all, he was like a mallet.

But he only had memory and didn't know the brain circuit of that unlucky guy, so he could only pretend to be profound and said slowly: "Why? You will know this question later."

Tailin took a deep breath and vaguely sensed the existence of some particularly deep conspiracy.

"...Yes, I understand." She said tremblingly.

Seeing that the other party was frightened, Lu En breathed a sigh of relief. If the other party pressed to the end, the secret might be exposed. Tailin didn't have to worry, but...

Recalling this, Lu En glanced at Kara.

The dragon maid is still so elegant and beautiful, her dragon tail is stretched out, she is holding a sewing tool that she did not know where she came from, and is sewing clothes for Lu En.

Even the Demon King has to wear clothes, but his original clothes have long been in tatters, but the maid can always take out some strange tools, such as needles and thread, from under her wide skirt to sew Lu En's clothes.

As for the suit he is wearing now, it is newly made.

Yes, it was newly made. Kara took the clothes of the human officers into pieces and then re-sewed them into garments.

What the maid has done is far more than that. Although there is no shortage of supplies, it is because they are robbing humans of supplies, and the human army is famous for eating shit. Some of their military rations are moldy, and even if they are good, they are just like shit.

It's equally unpalatable. Those dry rations are only distributed for survival. In the human empire and many kingdoms, the treatment of grassroots soldiers is incredibly poor. Some dried meat was even prepared fifty years ago and used as weapons.

There is no doubt that it can stab someone to death.

Of course it's okay for the orcs to eat these. They have good teeth, but when Lu En was about to eat these, Kara was the first to disagree.

She said seriously, 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 she served in the end looked like something from a restaurant with an average price of 8,000 yuan per person. She even put it on a plate and decorated it with dragon boat flower petals.

The dragon boat flower blooms in summer, and the current temperature even freezes the Blue River.

At that time, Lu En couldn't help but ask: "Where did you get it from? Magic? No, you should not have magic power."

"This is what a maid should do. Master, don't care about the work of our servants. 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, and this incident only made him more worried. Does this maid have any trump card? How can she still get dragon boat flowers and exquisite tableware now? In this world

I have never heard of space equipment. Even in a magical world, space technology is impossible. How did she do it?

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

After all, the top priority is to escape, and half of this goal has been accomplished.

Taking his eyes away from Kara, he continued walking towards the inside of the cave.

In the deepest part of the cave, it is not humid. On the contrary, it is quite dry. There is also a cool breeze blowing through, which proves that the cave is not closed, but has multiple exits.

There are many sacks placed deep in the cave, snatched from the hands of the coalition forces.

Most of the food in the pockets is grain, which is a kind of military ration that is steamed and mixed with wheat flour and corn flour. It tastes like eating sand.

Others are dried meat, which has been salted for at least ten years and cannot be chewed with teeth. Generally speaking, humans chop the flour and dried meat into pieces with a knife and mix them together to make porridge.

On the other side, there are some refined military rations, sealed in glass bottles, which are eaten by humans in emergencies. When the battle is most urgent, there may not be fire, water, or even turf to eat, so

These refined military rations were reserved for emergencies at that time. Lu En took a look and found that they contained animal meat sealed in oil. This was also the staple food eaten by the orcs recently. Humans were reluctant to eat this kind of thing anyway, so they grabbed a lot of it.

There’s no need to stay, and to be honest, this stuff doesn’t taste good. It’s cold, greasy, and salty. It’s far worse than the food made by Carla.

The rest are just some sundries, personal belongings carried by humans, ordnance, and armor, which are basically useless.

"We've almost collected all the stuff, so it's time to break out." Lu En looked over the looted supplies and his eyes stern.
