This earthy yellow shadow is expanding rapidly, the general direction is southward, but it does not mean that other locations are waiting still, after looking at it for a while, Fang Chen found that this earthy yellow shadow is also slowly expanding along the edge of the junction between the northwest direction and the real mountain plateau.

It's just that the expansion rate is much slower than the speed at which it goes south, and everyone's attention is on the big head, and it's easy to ignore it.

At the speed at which this earthy shade moves, it will not take a few months to expand into the reserve, and in addition to the rapidly rising waters, the land will also become a swamp.

Yu Yao felt that God might be playing a big joke with them.

The joke is called: I'm going to die with mud, and you're all going to die.

What a way to TM!

In order not to be played to death, they can only hurry up to see which general God has sent to dig for him in advance.

After a few days in the reserve, they were ready to head northwest.

The entire Northwest Territories are not heavily flooded due to the high terrain, except for a large inland sea between it and the reserve, the rest of the place is land.

At that time, when the tide of mutations continued to surge, they also thought about whether to retreat into the Great Northwest.

But the results brought back by the expedition team sent out were not good.

The living conditions were so bad that only 3 of the 25 surveyors who went there came back.

They set out in late summer and early autumn.

Of course, compared to the current change of seasons, late summer and early autumn also mean that winter is about to begin.

After preparing clothes to protect against the cold, the survey team set off, and then found that the winter in the northwest was not as cold as usual.

Without the slightest hindrance, the cold snap of Siberia drove straight down the Eurasian plate.

collided head-on with the 25-person survey team, and the horror of the low temperature was said to be a fight with the ice line spreading in Linhai City, which was an exaggeration.

But it wasn't far off, and after the first wave of low temperatures passed, 14 people were taken away from the survey team of 25 people.

The remaining 14 people were also taken away in the successive low temperature tides that followed. In the end, only 5 people were left to survive by hiding in a sheltered corner tower around them.

Finally survived the winter, and when spring came, the storm began to blow again, not the sky was slightly yellow, and the street scraped a little sand that was called a sandstorm, in the northwest, the sky was full of yellow sand, and the five fingers could not be seen, they were blown away by the wind and sand, and when the storm passed, only the three of them walked out.

Fortunately, it was the end of summer and the beginning of autumn, and feeling the morning breeze that was already slightly cool, Yu Yao was extremely hopeful that the Siberian cold current that swept the land could freeze the spreading earthy yellow shadow.

But it was clear that reality could not be as rosy as she thought.

Although the cold air has not yet come, just looking at the spread range of this swamp, Fang Chen pointed to the plateau snow line on the giant screen and said, this place is 5,000 meters above sea level, and the temperature is about minus 20 degrees.

The earthy shade is still active......

So it was Tuxingsun who sent it down?

When the weather was slightly cold, Yuyao Fangchen and Jin Fan set off with a team.

Because of the season, the purpose of this trip is only to survey, and once they encounter a low temperature tide, they will come back immediately.

Although it is not known what the reason for the expansion of this swamp is, according to the original Bo Zhu Ting, this should be a large group of animals that are good at drilling soil.

The low temperature tide may not freeze them to death, but it will definitely slow down their expansion, and there are still a few months to go, so there is really no need to carry the low temperature tide and them.

The time and place are favorable, and at least two must be accounted for.

Armed with equipment and supplies, they set out on the westbound road.

After a day's boat ride and two waves of mutations, they stepped on the land of the Great Northwest.

Yuyao clearly felt the surprise of the temperature, if it is still late autumn in the reserve, then here, it is early winter.

The north wind was already clearly carrying a bitter chill, blowing the withered yellow wheat grass from the vast field and blowing on the face.

Brother Yibing, who came with him, couldn't help but tremble, ripped off the thin cotton coat tied around his waist, and draped it on his body.

After walking for a while, they came across a small city.

The low earthen city wall, a few thin yellow grasses swaying gently on the wall. The breath of the whole city is like the grass on the wall, lifeless.

The group entered through the low gates, walked for a while through the streets of the city, and pushed open a few hidden doors.

But after shouting a few times, all that responded to them was the dusty bronze wind chimes at the door.

Jingle bells, jingle bells, muffled ringing, stuffy as if their mood at the moment, low and silent, there is a kind of deep sadness from the bottom of the heart, making people's nose sour.

The wind outside was getting stronger and stronger, and the sky was getting darker, so the group found an empty house in the middle of the city and went in, opened the door of the hall, and gathered a fire.

The people sat around the fire and ate the dry food they had brought.

Listening to the increasingly urgent wind outside, tired and tired, everyone silently held the dry food in their hands and ate quietly.

After eating, and adding firewood, the group lay down around the fire and their clothes.

It's just that for a while, everyone didn't fall asleep, Fang Chen unconsciously reached out and touched the land under his hands, I don't know if the people in the past were also sitting around like them, roasting the fire, talking, laughing.

The flickering flames blurred his eyes.

I fell asleep unconsciously.

The flames were still dancing, dotting with stars, dispelling the darkness around them.

Until a long wolf howl pierced the silent night.

The wolf howl was long and sharp, making Yu Yao sit up suddenly.

Fang Chen, who was sleeping next to him, also sat up.

There was still a little spark left in the fire, and Yu Yao threw the wood into it again, and the flames slowly climbed up along the wood.

Fang Chen stood up and walked to the door of the hall, and Yu Yao also stood up and followed.

The cold wind blew in through the crack in the door, and the wolf howls outside the door were getting closer and closer, as if Yuyao had heard the muffled sound of them stepping on the ground.

It's just that something is wrong, tilting his head and listening carefully, Fang Chen opened the door violently.

As soon as the door opened, in addition to the cold wind and wolf howling that poured in, there was also a rush of chaotic footsteps.

Fang Chen picked up the deadbolt and ran onto the street, and then saw a tall and thin shadow dragging a small shadow at the corner of the street, staggering out of the darkness.

Behind them were the sound of footsteps getting closer and closer, and then a group of gray-backed and white-bellied wolves burst through the darkness and chased after them.

The tall and thin shadow running in front of him was obviously chaotic, and he desperately dragged the doll in his hand, but he was still caught up by the wolves in a blink of an eye.

The northwestern wolves are much larger than the average wolf, with a long gray mane hanging down from the neck, thick limbs, wide webbed feet, and a fluffy tail hanging down behind them.
