After a somewhat oily breakfast, the sun was fully lit up on the edge of the snowy skyline.

Yanagihara wiped the oil stains from the corners of his mouth with his sleeve, and grabbed the snow on the ground and began to "wash" the blood stains on his body.

The stench of blood attracts wild beasts, which is common knowledge in the wild.

If Yanagihara was alone, she might not care about these details. But at this time, she was accompanied by an El, which forced her to start thinking about avoiding the beast.

She only had two bullets in her pistol, and even she wasn't absolutely sure that she would be able to protect a completely defenseless child in the pack with just a knife.

For ordinary people, rubbing snow on their bodies in the snowfield is undoubtedly a suicidal act, but for Yanagihara, it is no different from bathing by the river.

Her physical condition is completely inconsistent with scientific theories, and she has long been accustomed to this.

Al sat on the sidelines, watching Yanagihara lift his tattered shirt, revealing his muscular lower abdomen inside, and couldn't help but ask.

"Yanagihara, aren't you really going to be cold like this?"

She still couldn't understand why Yanagihara looked so relaxed, knowing that even in a cold-proof suit, it was difficult for her to resist the cold of the ice field in most cases.

And at the moment, Yanagihara only wears two clothes from the inside out, especially after giving her the coat, Yanagihara should only have one shirt left on his body.

But even so, Al still saw a slight chill in the wanderer's body.

Well, in fact, Yanagihara still has a short vest in his shirt, but this thing has basically zero ability to protect against the cold.

"Huh?" Listening to Al's question, Yanagihara was stunned for a moment, and then said perfunctorily.

"Maybe it's because I'm used to it, I've been on this ice field long enough."

"Really?" Al sideways his hair, apparently still having some doubts about this answer.

"Alright." Wiping most of the blood from his body, Yanagihara didn't wait for Al to ask the next question, but stood up straight to his body and said.

"Let's go, we still have a long way to go, and if you want to meet your sister sooner, it's best not to waste too much time here."

"Oh, uh-huh." Speaking of his sister, Al quickly got up and packed up his things.

She had just eaten a full meal, which gave her some mobility.

With El's help, the two put away their tents and other tools.

After that, they sat on snowmobiles and drove deeper into the ice field.

······

The next few days were boring, and with Yanagihara avoiding them, the two never encountered any wild beasts again, and Al could only nibble on the dried meat every day and miss the taste of the wild dog.

Just as most people find it difficult to become vegetarian after prescribing meat, she seems to be beginning to understand the true meaning of food.

You know, people on the ice field usually only regard eating as a means of survival, which is obviously a kind of degradation, a degradation of the mind. It is intolerable and unforgivable. It's just that right now, Al doesn't have such a deep obsession.

When she has nothing to do, Yanagihara will sit on her motorcycle and continue to write her letter.

However, it's like an online writer who has been stuck for three months, and for seven or eight days, she hasn't even written a word.

Fortunately, she seems to have gotten used to this normalcy and is not discouraged by it.

Yanagihara's shirt has been completely torn, and in its long life span of more than ten years, it has obviously experienced too much life to bear, so it can be regarded as the end of life. Yanagihara casually dropped it on the ground, and then left the old fellow.

At this time, she was left with only a brown coat and a tight vest, her angular lower abdomen exposed, and her flat chest appeared a little flatter.

With her oil-covered body, she looks like one of those sexy-dressed female repairmen in anime, but unfortunately, her figure isn't sexy at all.

In addition, Al seems to have had a special hobby recently, that is, when Yanagihara was driving, he sat in the back and secretly touched Yanagihara's belly, and the hard smooth touch seemed to make her love it. If it weren't for the fact that the ice field was too cold, she might even take off her gloves and touch them.

However, Yanagihara didn't notice this, she was just driving, well, simply driving.

This didn't last long, and on the eleventh day after leaving Greenhouse No. 3, the two finally saw a huge mountain range on the east side of the snowfield.

This means that Greenhouse No. 4 is almost there.

The No. 4 greenhouse in the west is also known as the Ring Mountain Greenhouse, because this greenhouse is built next to a huge crater mountain range.

The crater is like a natural barrier that stands in the back room of the greenhouse, shielding it from the wind and snow.

But the mountains also bring dangers, and there are large herds of beasts roaming around the mountains during the season when the beasts are active.

This makes it possible to cut off contact with the outside world at this time of year, drastically reducing the number of people going out and entering the greenhouse to avoid being attacked by wild animals.

But even so, many people die every year because of wild beast attacks, and the convoys used to transport resources and equipment in greenhouses are often besieged by wild animals.

If nothing else, this will obviously be the case this year.

So as early as two months ago, the greenhouse around the mountain has entered the warning period.

Since then, their guards have hardly relaxed, taking turns day and night, constantly monitoring the situation outside the greenhouse from the ramparts.

······

There was no snow in the sky on this day, so that the sun was a little dazzling, and at the foot of the rolling hills, the gray-black walls were scattered.

A scout in a winter suit is holding a telescope and looking at a snowy slope in the distance.

In order to facilitate the attack and deterrence of beasts close to the barrier, the barrier on the perimeter of the greenhouse is located on the outside of the greenhouse isolation layer.

Without the protection of the barrier covering the city, the environment of the outer wall is naturally also harsh.

The fluff on the Scout's collar was blown by the wind, and he wore a mask that kept him from breathing.

In addition to him, there was a whole team of heavily armed people standing on the ramparts.

There were about a hundred people, all of them with loaded rifles in their hands, and under the dark oxygen masks on their faces, a pair of eyes staring at the snowy field, as if waiting for something.

"Step." A footstep fell.

A middle-aged man with an armband walked up to the scout.

His face was like a knife on a rock, stiff and cold, with a look of caution in his eyes, and his right hand rested on his waist on the hilt of a saber. The back is straight, and the whole person is like a sharp sword, sharp and straight.

Judging by the military badge on this man's shoulder, he should be the captain of the guard of this greenhouse.

The dark blue military coat was pulled by the cold wind, and the middle-aged man looked at the scout and asked.

"Is that pack still there?"

Recently, a pack of wolves appeared outside the greenhouse around the mountain, and they were spotted half a month ago, and they have been wandering there for a long time and have not left.

With them there, it will be very difficult to get in and out of the greenhouse.

So today, the greenhouse guards of the greenhouse around the mountain are ready to drive this wolf pack back into the mountains.

The word wolf pack can be said to be two concepts in the post-disaster era and the pre-disaster era, and the difference is not in the definition, but in the difference of individuals.

In the pre-disaster era, wild wolves generally did not exceed two meters in length, 1.2 meters in height at the shoulder, and did not weigh more than 80 kilograms. However, the wild wolves in the post-disaster era, after being tested by nature, are usually larger than this number. Their average body length is about three meters, and some individuals can even grow to more than four meters.

If a wolf of this size attacks a human being in a pack, the consequences are usually unimaginable, and too many people who venture into the ice field die at the bews of these wild wolves.

"Report sir."

The Scout replied, fiddling his binoculars.

"They're resting on the side of the hillside and look like they're still looking for prey."

It was only a small wolf pack, numbering only about twenty, but the wolf king was a giant beast with a body size of nearly 4.5 meters, and at that point, it would be difficult for ordinary firearms to directly kill it.

"Hmph." The captain of the guard snorted coldly, and there was some suppressed anger in his tone.

"At this time of year, they come in search of prey."

The prey that these beasts are looking for is, of course, the cargo transported by humans and humans.

Whenever ordinary prey could not meet their needs, these beasts would invariably turn their attention to the human settlement, which is the reason for the gathering of beasts.

And when these beasts are driven into madness due to lack of food, they will launch a beast tide.

The herd gathers every year, but the beast tide does not occur every year, and it is certain that every time the beast tide starts, it is basically when the number of beasts is out of control.

And when the beast tide passes, the beasts whose numbers have been controlled will calm down again, and continue to reproduce while waiting for the next beast tide to begin.

This is like a form of natural selection, in the current environment, any living being, including humans, must compete with other living beings in order to fight for space to survive.

But space is limited, so they have to consume each other in order to survive stably.

"Sir." The scout with the telescope suddenly frowned and said.

"The wolves seem to be approaching the greenhouse."

"Then let them come." The captain of the guard spoke in a dull tone and put his hand on the barrier.

"As long as they're in range, don't let them go."
