"Now, let's talk about the problem of the defense line!" Colonel Slain calmed down and said: "The good news is that the command has agreed to airdrop supplies for us, but because the air force wants to help the Northern Army get out of trouble, the airdrop supplies are temporarily limited!"

The officers couldn't help but breathe a sigh of relief when they heard this, which at least showed that the command did not give up Holm.

It is actually understandable that commanders do this. At this time, three Soviet armies interspersed towards the rear of the German Northern Army Group. Once the interspersed successfully, it means that the German Northern Army Group may be completely wiped out. Of course, the air force must first assist the Northern Army Group in retreat.

"From the afternoon, they would airdrop weapons, ammunition and 4 tons of flour for us every day!" Colonel Slein said: "We can assume that the supply problem has been solved, the point is... we don't seem to have a place to keep the cold. You know, the Soviets would destroy all the house floors, and the reduction of staff caused by the cold can be predicted to be more and more serious!"

"Yes!" Gerhard nodded and said, "They don't even need to do this, they just need to attack every night at the coldest time!"

"We don't even have a place to make bread!" said Bazer.

The officers couldn't help but fall into silence. These problems were indeed very difficult.

"College!" Qin Chuan said: "The fundamental reason for this problem is that the Soviet army has a large number of artillery but Holm does not, or the Soviet army has an absolute advantage in artillery, so the enemy can make fires at night but the German army cannot!"

Colonel Slain nodded in agreement: "But what can we do? Captain, can they airborne artillery to suppress them? This is almost impossible!"

"No, colonel!" Qin Chuan replied: "Maybe we can make fires in a safe place, such as cellars, where almost everyone here has cellars!"

"No, Captain!" Colonel Slein shook his head and said, "Someone has done this. Although it can prevent the fire from leaking, the cellar is not ventilated and fire can easily cause oxygen deficiency. Some people even made a chimney out of the cellar, but do you know what happened? The Soviets opened fire on the Mars that came out of the chimney... They were all buried inside. Although we dug it out, this method didn't seem to work!"

"Hmm!" Qin Chuan said: "They opened fire on Mars!"

"Yes!" said Colonel Slain: "It may be not just Mars, but they can see the burning black smoke!"

"So... why don't we make the chimney longer!" Qin Chuan said: "I mean, let these black smoke and Mars come out from other places."

Upon hearing this, the officers were stunned and then excited:

"Well, why don't we connect the chimney to other places? Like a house that has become ruins!"

"In this way, the enemy's shells will fall on these ruins!"

"We can even connect a few more chimneys so that one chimney is blown up and the other chimney can be used again!"

...

"I have a problem!" Lieutenant Colonel Gerhard asked Qin Chuan: "Captain, we know... the Soviets are blowing up our buildings one by one, which means we will be buried in the cellar after another!"

"I don't think so, Lieutenant Colonel!" Qin Chuan said: "The Soviets built cellars are very strong, and often the buildings on the ground are blown up and the cellars are intact!"

"With that being said, the exit will be buried!"

"Why can't we dig an exit outside the house!" Qin Chuan said: "This way, even if the building is blown down, the cellar can still be used normally, and even because there are many bricks and tiles on the ground, it will be stronger!"

After pausing, Qin Chuan added: "We can even dig two adjacent cellars to connect them into one, or open them to the trenches and the trenches to form a defense system!"

The officers were stunned when they heard this.

After a while, Colonel Slain said, "Captain, you seem to have moved the fortifications here!"

"Why not?" Qin Chuan said.

"Yes, why not?" Colonel Slain said with a smile: "We are a force with experience in building tunnels, why can't we think of these!"

"Maybe..." Bazel said: "Maybe because there are many houses here. We built them on the high ground before, so..."

"So, what are you waiting for?" said Colonel Slain: "Do it, for the warmth and sleep of the evening!"

The officers couldn't help laughing.

Then the German army did what they said and assigned the tasks in a piecemeal manner. Each platoon was responsible for a cellar... The German army had 48 people in a platoon, but usually there were only 30 people in a platoon.

Even so, a cellar crowded with more than thirty people.

However, they should not be crowded inside. Some people must be guarding the trenches and then rotated, so there were no more or fewer people living in a cellar.

The first one to be renovated was the chimney.

In order to ensure the bearing capacity of the cellar, the chimney did not drill holes from the top, but dug an oblique passage from the side wall of the cellar to the ground, and then connect it to the ruins a hundred meters away with a drainage pipe as thick as a bowl... The distance must be at least 100 meters, otherwise a shell would hit him or her after the Soviets discovered the smoke.

The ventilation hole is connected with two other pipes, which is relatively simple. You only need to expose the ground and then put an air vent at the pipe interface... The so-called air vent refers to making the pipe turn a bend in the direction of the wind. On the one hand, you can rely on the power of the wind to pour air into the ventilation pipe to make the ventilation better. On the other hand, you can avoid snow accumulation, mud and water caused by shells to block it.

This is also thanks to a water pipe factory on the east coast, where iron pipes of all sizes are available in the warehouse.

After the soldiers transformed these, they couldn't wait to try it out, which was to create a small fire in the cellar.

They even made a simple stove with gasoline barrels, with a large mouth above the oil barrel placed a pot, a chimney at the lower part, a rectangular mouth opened at the lower part to serve as a firewood entrance, and a ventilation duct on the side, which can be used as both a stove and a cooking utensil... It is simply perfect.

Then a pile of fire soon burned in the oil barrel. The soldiers greedily reached their frozen hands in front of the flames while listening carefully.

Soon, a row of shells came, but judging from the vibration, it was obvious that it was not the location of the cellar.
Chapter completed!
