In the wild at the end of the world, no one knows what dangers will be encountered, and dare not really fall asleep, so Lin Feng just rested. Although there is a laser anti-theft system at the entrance of the cave, he must not be careless in the wild.

It is now the middle of the night, when Lin Feng was half asleep and half awake, the little silver wolf was sleeping on Lin Feng's shoulder, but suddenly, the little silver wolf's pink ears pricked up, and at the same time, he opened his eyes. Eye.

The next moment, the little silver wolf stood up abruptly, with silver hair standing on end, got up and walked to the corner of the cave, raised his head and looked towards the cave entrance.

"Aw!"

A childish howl came from the mouth of the little silver wolf. Although the sound was a little different, it looked very much like the howling of the silver wolf during the day.

Hearing the howling of the little silver wolf, Lin Feng, who hadn't slept well, woke up immediately from his sleep.

"Did the little silver wolf discover something?"

The hearing of the wolf is stronger than that of the dog. Seeing the appearance of the little silver wolf, Lin Feng immediately became alert and stood up at the same time. Lin Feng walked to the corner of the cave. But Lin Feng didn't show his body, but poked his head out a little to check the situation at the entrance of the cave.

At this moment, Lin Feng saw a figure outside the cave, slowly walking towards the cave.

"Woooo..."

Seeing the figure outside, the little silver wolf made a threatening voice.

By the moonlight, Lin Feng saw the appearance of the figure at the entrance of the cave.

It was a zombie with an ugly face and a black complexion. This zombie was tall, and most importantly, this zombie had four arms.

Probably seeing the little silver wolf in the cave, this zombie walked towards the cave.

"hold head high!"

One of the zombie's arms touched the laser alarm device at the entrance of the cave, and the alarm sounded loudly.

The zombie was obviously startled by the siren, roared, and walked towards the cave.

Lin Feng took out the short crossbow from the post-apocalyptic watch. Although he didn't know what level this zombie was, it had four arms, and it was obviously mutated.

What Lin Feng didn't expect was that just as he took out the short crossbow from the doomsday watch, the little silver wolf rushed towards the zombie.

Seeing the little silver wolf rushing towards him, the zombie let out a loud roar, and slapped the little silver wolf with one of its four arms, trying to knock the little silver wolf away.

But what no one expected was that the little silver wolf directly bumped into the zombie's arm, and even made the zombie take two steps back.

The size of the little silver wolf is less than half the size of the zombie's arm, and it takes a lot of strength to knock a zombie that is bigger than Lin Feng back.

The zombie did not expect that the little silver wolf would have such great power. All four arms stretched out, grabbing the little silver wolf.

The little silver wolf opened his mouth, and a wind blade with silver light flew towards the zombie.

Seeing the actions of the little silver wolf, Lin Feng was stunned.

This wind blade Lin Feng had only been seen in games or science fiction films before, but he never thought that he could spit it out from the mouth of the little silver wolf.

The speed of the wind blade was very fast, and it hit the zombie's arm in an instant. The wind blade passed through the zombie's arm and cut the arm in half. One of the zombie's hands fell to the ground.

Immediately afterwards, the little silver wolf opened its mouth again, and two more wind blades flew out of the little silver wolf's mouth. The speed was so fast that the zombies couldn't react at all.

One of the two wind blades hit the zombie's chest, and the second hit the zombie's head impartially, splitting the zombie's head in two.

The zombie that received a fatal blow to the head lost its source of energy, and fell to the ground with a "plop".

Lin Feng didn't close his mouth from the beginning to the end. He didn't expect the little silver wolf to be so powerful. Leaving aside the level of that zombie, a thing that can send out wind blades is already very powerful.

Since coming to this end of the world, most of what Lin Feng has seen are battles with hot weapons. Even some practitioners like to use cold weapons, but they have no tricks. And Lin Feng has never seen those supernatural abilities in the movies before in the last days. For a long time, Lin Feng thought that those things were fake and existed in the world of science fiction, but he never expected to see them with his own eyes today.

But Lin Feng can accept it after thinking about it. Isn't the blood gene he exchanged in the super energy exchange system in the supermarket also unreasonable? Since the gene of face and blood can be changed, there is nothing to be surprised about the appearance of the wind blade.

Lin Feng looked at the hero of this battle, and saw the little silver wolf lying on the ground, looking a little tired. Looking at the little silver wolf's appearance, it is estimated that sending out three wind blades may be the limit of the little silver wolf.

He took out a few white crystals from the doomsday watch, and sure enough, when the little silver wolf saw the white crystals in Lin Feng's hands, he immediately stood up, wagging his tail, salivating.

Putting Bai Jing on the ground, Little Silver gobbled it up, hiccupped, and the little guy lay down again.

Ignoring the little silver wolf, Lin Feng came to the corpse of the zombie, through the zombie's head that was cut in half by the wind blade issued by the little silver wolf, Lin Feng saw a yellow crystal in the zombie's head.

Picking up the topaz, Lin Feng saw that the crystal was dark yellow, with hints of green inside.

A third-level zombie who is about to be promoted to a fourth-level zombie!

Seeing this crystal, although its color is dark yellow, there is already green in it, which means that this third-level zombie is about to be upgraded to a fourth-level zombie. From the mutation of its four arms, it can be seen that this kind of situation is impossible for ordinary third-level zombies.

In the apocalyptic world, zombies below level 4 will generally not show obvious mutations, while zombies above level 4 will more or less mutate. Some of these mutations are external mutations, and some are inner body mutations. And the zombie in front of him was obviously a zombie about to be promoted to level four, and had four arms mutated.

Lin Feng is not the opponent of the fourth-level zombies now, but he did not expect that the little silver wolf can kill the zombies that are about to be promoted to the fourth level. Now Lin Feng not only has to look at the little silver wolf with admiration, but if there is a real fight, I am afraid that Lin Feng himself will not be the opponent of the little silver wolf.

No wonder the group of zombies besieging Lin Feng retreated when they saw the silver wolf during the day. Even the little Silver Wolf can kill zombies who are about to reach level four, let alone Silver Wolf. Looking at the strength of the little silver wolf, Lin Feng estimated that the silver wolf has at least reached the standard of a third-level mutant beast, or even higher.

After the intrusion of the zombies, Lin Feng no longer wanted to sleep. Seeing that it was already the middle of the night, Lin Feng was going to absorb Huang Jing's energy. Even the little silver wolf with a face is so powerful, Lin Feng thought to himself that his strength is still too low.
