It was late at night and everyone was asleep.

Yang Xiao's hearing was the most sensitive, but he fell asleep, and Long Yongjun slept 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 back, 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.

Yang Xiao 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.

Yang Xiao 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, Xu Nanqiang 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 mutated 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 gate 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.

Yang Xiao 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.

Yang Xiao quietly got out of bed, and at this moment, Huang Wen, Xiao Zhe, and Zhao Gang all came over.

Everyone lowered their voices and talked quietly.

"Yang Xiao, 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."

......

Yang Xiao thought briefly for a moment and said:

"Huang Wen, 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."

Yang Xiao asked Xiao Zhe 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 Ma Junhui designed the entrance of the cave, he designed a climbable staircase ring inside, which was inlaid on the cave wall.

Yang Xiao 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.

Yang Xiao only glanced at it, and he was startled.

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

"Damn, how could there be so many mutated animals overnight?"

Moreover, the mutated animals seemed to be clever enough to deliberately avoid the orange light emitted by the gene store, just to hide in the dark.

The cave on Yang Xiao's side was still 200 meters away from the gene store, 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.

A pair of green eyes approached the edge of the orange light, about 3 or 4 meters away from the orange light, Yang Xiao used the faint orange light to vaguely see the silhouette of an animal more than 2 meters high, the animal seemed to be afraid of the orange light, the figure flashed, and disappeared into the night again.

The shouting outside did not stop, and after half an hour, there were probably hundreds of pairs of large green eyes in the dark night outside.

The green eyes gradually gathered together, as if negotiating something, and after a moment, a loud cry rang out:

"Whew-"

Then, Yang Xiao was surprised to see that these big green eyes in black began to move in the direction of the cave, and they were getting closer and closer.

"Damn, are you going to attack us?"

Yang Xiao jumped down from the iron ring of the wall and immediately found Chen Lu.

"Chen Lu, gather all the elemental magicians, especially the electric magicians, how many electric elemental magicians do we have?"

"There are more than twenty."

"Okay, the electric magicians are divided into two groups, standing in front of the iron gate of the cave, if the monsters outside attack us, use the electric magic with all their might, and just hit the iron door directly, understand?"

"Hmm." Chen Lu nodded.

"Remember, don't use the Fireball Ice Ball Wind Blade, don't knock down the iron gate, or we'll die an ugly death."

Yang Xiao also asked Huang Wen to organize a feather arrow team, and put more than a dozen people at the entrance of the cave on both sides, because the location of the cave was limited, and it was impossible for too many birds, beasts, and souls to attack.

"If the iron sheet on the iron door at the entrance of the cave is scratched, just shoot the feather arrows vigorously."

"Xiao Zhe, Zhao Gang, Dai Yun, Long Yongjun, Fei Fei, you organize a melee beast soul team to stand in the first row of the cave, no matter what, you must guard the entrance of the cave to the death, and you can't let the mutated creatures outside rush in."

"Take a dozen flashlights to the back, and the animals outside only need to rush in, shine flashlights in their eyes, and point out the targets of attack."

......

After some tense deployment, everyone was ready to fight, Yang Xiao climbed the iron ring at the entrance of the cave again, looked out through the lattice above the iron gate, and saw a group of green eyes in the darkness getting closer and closer, and after a while, only about twenty meters away from the cave, these monsters stopped.

Yang Xiao knew that this was their preparation to attack.

Yang Xiao fixed his legs on the iron ring, reached out and took off the finch bow behind his back, mounted an arrow, and aimed at the green eyes in the darkness through the lattice window.

Yang Xiao originally wanted to use one finger to split the ground, but he was a little worried, now using this beast soul skill through the iron gate, would he accidentally blow down this iron door?

Without the protection of the iron gate, it would be miserable.

In the darkness in the distance, green eyes lined up in a long line.

Yang Xiao took a deep breath and bowed the full moon.

Woo –

A loud scream rang out outside, and then a roar was heard, and dozens of pairs of green eyes rushed madly towards the mouth of the cave.

As soon as Yang Xiao's hand was released, a feather arrow broke through the air, cut through the night, and went straight to the pair of green eyes at the front.
