Most of the buildings in Shashi have collapsed, and a small number of commercial office buildings are relatively intact, and the heavy snow can only cover the streets and the outside of the buildings, and there are a lot of wooden furniture inside the buildings that can be used to keep warm.

In addition, the food here is relatively abundant, there are hundreds of large supermarkets, and there are countless small supermarkets, so everyone has no problem eating.

Although people in urban areas are just as cold, the mortality rate is much lower.

Their only problem now is that they can only move in the subway passage and the buildings connected to it, and they can't easily run outside to do activities, otherwise, they will suffer frostbite at least and freeze to death in severe cases.

The severe cold has limited the range of movement of most people, and the world is dead.

Until one night, Ye Tian and the others were sleeping in the cave, when suddenly, a strange cry came from outside:

"Whew-"

It was late at night and everyone was asleep.

Ye Tian's hearing was the most sensitive, but he was asleep, and Long Yongjun was sleeping next to him.

Stewed broth tonight, he drank two more bowls, at the moment he was a little holding his pee, he wanted to get up to pee, and he was afraid of the cold outside, so he kept holding it, and he couldn't fall asleep when he woke up.

At first, he didn't care, but after a while, a strange cry came from outside:

"Whew-"

This time, the cry seemed to be near the cave, and the sound was very real.

Long Yongjun's current level of genetic evolution is also quite good, and his auditory senses have been greatly improved compared to before.

Hearing this cry, Long Yongjun sat up from the bed with a spirit.

Because of the cold, everyone slept with clothes and quilts.

Long Yongjun pricked up his ears and listened carefully.

"Whew-"

There was another scream, and it seemed to be closer to the cave.

Long Yongjun's heart sank.

This time, Long Yongjun was not the only one who heard the scream, more than a thousand people sleeping in the cave, at least a dozen of them were awakened.

Ye Tian was also shocked in his heart, and when he looked up, he saw Long Yongjun sitting on the bed listening with his ears up.

"What's the situation?"

"Shh

Long Yongjun made a shushing motion.

Ye Tian hurriedly got up from the bed.

The two entrances and exits of the cave are blocked at night by iron gates, which are welded with angle iron and crude steel.

At the beginning, Wen Yongchuan and others found a few generators in the building materials market, and also found two welding machines to weld the steel frame, and later welded two large iron doors by the way.

In order to block the alienated creatures that may haunt at night, the lower part of the iron gate is covered with iron sheets, and the upper part of the iron door is only made of iron lattice, which facilitates the air circulation of the cave at night.

At this moment, the people in the cave basically woke up, and those who didn't wake up were quietly called by the classmates around them.

There are several boxes of candles and more than a dozen flashlights in the cave, which are usually used in emergencies at night, and are usually not used.

Ye Tian instructed everyone not to light the lamp, to hear what the situation was first, and everyone should wake up and get dressed, take their weapons, and prepare for battle.

Everyone quietly passed one by one and told everyone to move lightly and try not to make a sound.

Ye Tian quietly got out of bed, and at this moment, Wu Yi, Chen Ping, and Zhao Gang all came over.

Everyone lowered their voices and talked quietly.

"Ye Tian, there seems to be the cry of a beast outside."

"This cry sounds so familiar, it feels like a wolf."

"Wolves? How can we have wolves here? ”

"Wolves are hardy animals, and in the past, in the Tianshan grassland, there were wolves infested with minus 40 degrees in winter."

......

Ye Tian thought briefly for a moment and said:

"Wu Yi, Zhao Gang, you take some people to the other cave entrance to be on guard, we have the protection of the iron gate, don't be afraid, as long as they don't take the initiative to attack us, we don't have to provoke them, everything will be dealt with after dawn."

Ye Tian asked Chen Ping and Long Yong to lead some people to guard the iron gate of the cave here to prevent the attack of monsters.

There was tension in the cave, and most people's hearts were pounding and racing.

In the last days, humanity has become weak.

When Zhang Jicai designed the entrance of the cave, he designed a staircase ring that could be climbed inside, which was inlaid on the cave wall.

Ye Tian walked to the entrance of the cave, ran up along the iron ring on the wall, and then looked out through the lattice window in the upper part of the iron door.

Ye Tian only glanced at it, and he was frightened.

In the vast night, there were at least dozens of pairs of big eyes that emitted green light like electric lights, and Ye Tian knew that they were the eyes of alienated animals.

", how can there be so many alienated animals overnight?"

Moreover, the alienated animals seemed to be very clever and deliberately avoided the orange light emitted by the genetic exchange, just hiding in the dark.

The cave on Ye Tian's side was still 200 meters away from the gene exchange, and it was still about 100 meters away from the edge of the orange light, and it was not under the protection of the orange light.

"Whew-"

The shouts outside came and went, and it was very frightening.

As the cry rang out, a moment later, large eyes with more and more green light appeared in the darkness.
