Don't fight uncertain battles.

Keep moving and fight, hit and run.

Let the enemy be the supplier of the main weapon.

Keep your whereabouts hidden.

Military action must be taken by surprise.

Immediately after the seizure of some power, new columns were to be formed.

Generally speaking, the development of guerrilla warfare goes through three stages: strategic defense; The enemy's actions are in a stalemate with the guerrilla movements; Finally destroy the enemy once and for all.

———————— Che Guevara, from On Guerrilla Warfare

Many people felt that guerrilla warfare within a few kilometers of the complex and only a few kilometers was impossible, but with enough small formations, enough elite troops, and a strong will to cross this, and with a constant supply of cover and supplies from the Imperial Guard's camps, the situation faced by the Katakáns was not as bad as one might think.

For example, the pitch black environment here, even the continuous lumen towers on the castle have many dead corners, and the underground is wet and dark, which provides them with a lot of convenience.

Of course, danger still accompanies them, and with the radio strictly controlled for safety and not exposure, Katakan can only rely on ghostly walking in this poor area to get his chance.

Not far from the Space Marines camp, the heavy reinforced concrete walls and guns of the notorious traitor's makeshift defenses are timid, the terrifying ornaments or mutated bones, and in any case, the deadliest are the statues of the Space Marines standing on the walls.

Master Chief Katachan and his "water team" were lurking, holding binoculars and draped behind him with a piece of broken iron sheet and cloth sewn from the ground, which was broken by the war, and the equipment of the auspicious cloak to keep him quiet enough.

Absolutely silent, they looked like a stump of splinters that were stable enough after the pipes made on the ground for heat exhaust, no different from the other "sibling" fragments that had emerged from the war.

"It's only a group of about 5 kilometers, and the density of Astarte is not that high, and most of them are mortal defense lines composed of cultists." Sergeant Katachan whispered to the Lightlin Kid beside him, emphasizing.

"You don't need to follow us, we don't have cooking needs, and we'll be out of the camp area for a long time, the only way to contact the camp is regular supply distribution and flares, you can't hold on."

Kid Leterin just replied. "I'm small and stealthy, and proficient in drilling pipes, and secondly, my shooting skills are far better than yours, Master Chief, and I understand that subhumans like me are not welcome, especially since Leterin has a problem touching the supplies of his comrades, but I swear to the Emperor that I need to repay the Sun Lord."

"Let me help you, my brother." He said heavily to Katachan.

The Master Chief was silent, he looked into the distance, and uttered something completely different from the Lytherin Kid's question. "The wall is about three meters high, not too much, but there is barbed wire on it, and it is impossible to break through head-on, I think the hot melt grenade is good, it can melt the wall, but how to create a breakthrough?"

This is Katachan-style dialogue, and if a Katachan talks to you like that (asking for tactical advice) then congratulations, you've been accepted by the toughest tough guy in the universe.

The Leterin Kid hesitated, then smiled again, and replied in the same lively, kind, and foul manner as usual. "How about a grenade, smash a single grenade into the enemy's wall with a hot melt."

Sergeant Katachan shook his head. "No, the yield is a matter of volume, you have to have a thick bouquet of hot-melt anti-tank mines, but our best bombardiers only have a range of tens of meters."

The Lighterin Kid groaned. "That's still a sniper handle, as long as the enemy's losses are too large to maintain a large defensive line, it's not difficult to get through the weak manpower, but..."

Sergeant Katachan couldn't hear their conversation, and he couldn't read the verbal movements to speculate on the situation, but he still needed to be quiet and pay attention to the situation here to determine the strategic objectives.

In the blurry images and the telescope's black-and-white high-contrast night vision, the mechanics handed the black boxes to the Space Marines, and after inspecting them, the servants sent the treasures into the towering fixed machine gun tower.

"I'm willing to bet it's a blaster, and we need to figure out this supply line and cut it off." Master Chief said.

Kid Leterin asked. "But we are inside the encirclement, how can we hit the people outside?"

"The dam is easy to hold against the river but does not block the raindrops, and we are very few in number, and we can enter the perimeter through the pipeline, which leads in all directions, and it is not difficult to get out, but it is impossible for the large army to evacuate." Sergeant Katachan replied.

"Isn't that my forte?" Leterin Kid said.

Yes, there are a lot of pipes in this place, and those things are blood vessels, trachea, which are all over the place and actually useful for the Empire's mega-buildings, but this place seems to draw heat from the center of the earth to generate electricity, in other words, if you find the wrong pipes, they will be burned into char by the underground heat.

This task is very heavy and terrible, and inexperienced people cannot distinguish between them, and the Lighterin Kid should be the best candidate, the candidate to leave the encirclement with the guerrillas, and at this moment, Sergeant Katachan saw the change of the enemy's reconnaissance team, so he stood up and walked with his troops to the vicinity with great speed, leaving the area.

The Lettling Kid pointed out a possible pipe entrance nearby, and it should be concealed enough, and the Catachans moved forward quickly and quietly, and they soon came to the location indicated by the Lettlings, a sewer pipe that was downwards and hidden in the semi-protruding ground to drain the waste liquid.

The Lettling Kid stroked the blurred text at the mouth of the pipe, which seemed to be hundreds of years or thousands of years? "It should be a reclaimed water (recycled water) pipeline, no corrosiveness or radiation, a rare good thing."

"How can you tell?" A Katachan recruit fussed and asked, as a native of Chaodu, he was not sure that there was a pipe in this location, and even if there were, he could not understand whether this thing was emitting radioactive water.

"I can feel the history of the pipe when I touch it, sir, I am different from people like you, I was born in it, and spent most of my years, and I know the common pipes of the Empire." It was rare for the Letherin Kid to say so loudly to an elite like Katachan, this is normal in the Empire, in an environment where force is worshipped.

There are not many days to be able to act in front of Catachan, no matter how hard the next guerrilla war is, the Leterin kid feels that it is worth it at the moment, until he subconsciously opens his individual energy bar, he becomes hungry because of this incident, and then is scolded by the master chief. "Don't eat it! We have a week left until our next replenishment! ”

The Leterin Kid touched his backpack, about 15 kilograms of food, and a carbine, a full 40 kilograms without body armor, but a week?

He habitually needs to eat breakfast, brunch, lunch, lunch and dinner, afternoon tea, dinner habits are completely different, usually he can eat the whole backpack food in a day, although the individual rations here are high-energy, a small stick in his hand has 400 kcal, but for the Lettling kid not to eat is painful!

Regretted, he regretted it a lot, but he just carefully put away those things, but he did not retreat, but as a soldier with a new clan that he was not blood, he was born in the pipe, walking into this dark and dark place is like returning to his hometown, the sound of military boots clattering on the ground continues, he takes the lead in guiding the blind dog in the intricate pipes to carve out his own path.

And the pipe is not for humans, it is crooked, the bones are strange, up and down, very deadly, but it is nothing to the Leterin Kid, even if he has no equipment, he can climb those things through the fluff on his fingers, even if the walls of the pipes covered with moss are smooth, he can go up like a spider climbing.

His exploration was useful, and when he returned, he would bring with him a lot of rodents to fill the gaps in food for the troops, as Katachan was struggling in the pipes, and the animals were good at alleviating the supply problem, although the Lettling Kid still lost a lot of weight during the two-day journey.

It's hard to imagine that the little body has anything to do with gluttony except for a slight bulging belly, but the reality is that the food consumption of the Lettling people is far greater than that of ordinary people, and the good news is that the Lettling Kid has endured hunger for a long time due to exclusion and rioting when he was on Pan Lan, and the lack of food does not make him incapacitated.

And his strong will was indeed recognized by the Katachans, and the forest warriors also proposed to give food to the Lettling Kids, but the Lighterin Kids, who knew how important food was, all refused, and it was hard to imagine that the Lettlings in the name of petty theft within the Empire would do such a thing.

But the reality is that as a soulless person, he has very little contact with mainstream Leterin society in his life, and stealing is rare, and he is not one of those notorious fellows, but the emperor gave him a birth that is like this, stinky, and full of disgusting elements.

The method is destined, he is no different from those rodents in the pipe, just like his birth, destined to be ostracized and disgusted, but Skadi is different, the sun lord is different, the war is different, the empire will unconditionally love those who sacrifice at this moment, and the emperor will protect those who fight for the empire on the battlefield, even if he is born cheap.

This is what most of the warriors of the Empire think, and it is the Imperial Guard that gives them the opportunity to change, from the waste of the nest capital to the veteran who is in charge of his own affairs, to express his worth to the Emperor, to prove his existence to the Empire, to express those resentments and gifts.

Lytherin Kid would use a knife to carve a mark on the metal pipe at each bend of the pipe that could only be distinguished by touch, so they could avoid many places, trial and error through the labyrinth of pipes, and he could also discern the nature of the pipe by the touch of the carving.

Therefore, he promised that the Imperial Guard would be able to cross the place in less than a tenth of the time it is now, and of course, it would be a problem that only he could understand the mark.

And when the last rays of light from a long trip were sprinkled in front of them, it was a pity that it was not the warm and comfortable sunlight but the disgusting glow of the Lumens Tower, and the lack of ultraviolet rays was uncomfortable, even though most of the Nest people were used to such feelings.

Didn't go into the wrong pipe, the two-day march paid off at this moment, there was no doubt that the Leterin Kid was a hero and a miracle, but people don't usually cheer for him, but today, his head sticking out of the pipe was held down by a thick arm, said in a magnetic voice. "Well done, bro."

That was Katachan's voice, that was Katachan's approval, and after three years, the team accepted outsiders again, but the situation was much better than the despair at that time.

And when the Katakhams leave the inside of the pipeline, which is the rear of the battle line and the free world that the Skadis dream of at the moment, their strength cannot break through the enemy's encirclement and return to the surface to launch intelligence, but can only methodically study the situation in this underground cavern like a tattered metal garbage heap.

They quickly found a road that had been artificially cleared, wide enough to pass through the Emperor's Poison Blade, and the tires on it told them that there were many things passing here, such as transports.

"This is it." The Master Chief judged time with his prostrate body like a hound. "It's been more than a day, and I haven't passed through the car body for a day, but there are traces left the day before yesterday or the day before yesterday."

"Is that the mech-cult's convoy?" Kid Leterin asked.

"Almost, if not transporting food or something." After the Master Chief finished speaking, the Lettling Kid's stomach gurgled and made a sound, and the Lighterin Kid immediately shrank his head for fear of being scolded, but the Master Chief looked at the thin guy and sighed.

"Go to the pipes and make a smokeless fire with promethium and iron buckets to prepare food for us." Then pull out your own supplies, canned meat, starch, canned beans, salt, sugar, and so on.

"With the food here, my physique is better than you carry 20 kilograms of things." The Master Chief took out the food and reserves that should have been in the emergency, which was not rational, but he rarely relented, and secondly, the Lettling Kid was the secret of their return, or to replenish their physical strength and maintain morale, cooking and rest were also crucial.

But everyone understands that he is making excuses, and for the first time, this man who has never cared about others because he has grown up to show weak feelings for his brother and compatriots, and finally turns into words with only lame excuses, and it turns out that there is no superman in this world.

No matter how powerful and powerful you are, as long as your spirit and will are still human, you can't help but feel feelings about something and care about the things around you, and the whole universe is not only about war.

As the flames rose from the pipes, the Lightling Kid wiped the liquid off the pipes, making them dry and comfortable, making frying pans out of tin sheets, making pots and pans out of iron buckets, making thick soup out of beans, and making steaks out of canned food and starch.

Katachan and Letrin, two groups of people who could never get along, shook hands in Skadi's home, while the nezumi and the ape, sitting in a metal cave, shared their food.

Damn, I forgot to change the title (casually typed)

This chapter should be called the ape and the mouse
