A little evolution point was not enough for Duan Fei to improve his other abilities, so he didn't rush to use it.

So far, Duan Fei has only upgraded the attribute of strength, from level one to level two, but if he wants to level up again, he needs six evolution points, which means that Duan Fei must kill six walking corpses in order for his strength to be upgraded.

Duan Fei took a general look, and at present, except for the strength being level two, the other attributes of his body are only level one

Agility level, if you level up, you need three evolution points;

At the first level of exploration ability, two evolution points are required to upgrade;

At the first level of mental power, ten evolution points are required to upgrade;

"Mental power!"

When Duan Fei saw the attribute of spiritual power, especially the "Evolution requires ten evolution points" displayed behind it, he was slightly stunned, and a look of surprise flashed in his eyes.

To upgrade the strength from the second level to the third level, it only requires six evolution points, and this spiritual power, just from the first level to the second level, it actually requires ten evolution points.

Of course, surprise is surprise, when Duan Fei thought of the rumors about spiritual power in the Dark Ages, he was also much relieved about these ten evolution points.

In the Dark Ages, the only way for humans to fight those mutated monsters was those awakened with different abilities, and different awakened people had different abilities, and among these strange abilities, there was an extremely powerful ability, that is, "spirit".

Unlike the Awakened who uses the genetic nucleus in the body of a mutated walking corpse or alien beast to obtain the ability, the owner of the "spiritual" ability is a natural awakening, and once awakened, his initial power is enough to compete with the C-class Awakened.

Aerial repellents, spiritual force fields, and spiritual attacks are invisible and formless, and there is no way to defend against them. In the previous life, there was a strong man with the ability of "spiritual force field", when the beast tide came, he walked alone in the wilderness, within a radius of ten meters, as long as a monster stepped into it, he immediately died, and one person solved the almost endless monsters in the beast tide, which shows how perverted his ability is.

However, there were only a few owners of the "spiritual" ability in the whole world, and each of them was a peerless powerhouse who dominated one side, and in his previous life, Duan Fei was not qualified to contact them at all, so he didn't pay too much attention to it.

According to the current state, Duan Fei knew that every level of spiritual power was raised, a large number of evolution points were needed, and as the level increased, the demand for evolution points also increased, and it was almost seven times, eight times, or even more than ten times.

If you want your mental power to reach the level of ability, Duan Fei needs to at least upgrade it to about level ten, and the number of evolution points required is incredible, and for the current Duan Fei, it is simply an impossible task.

After thinking about it carefully, Duan Fei decided to upgrade his strength first, followed by agility, and then his probing ability. Spiritual power is not considered for the time being, after all, Duan Fei's current ability is limited, and it is extremely difficult to obtain evolution points, and every evolution point must be used on the blade.

After dealing with this walking corpse, Duan Fei came to the eleventh layer.

Similarly, there are two houses on the eleventh floor, with the gates facing each other. However, in front of one door, a large pool of blood flowed out of the house, which dragged on for a meter.

Looking at the pool of blood in front of him, Duan Fei's eyes were cold, and in his cold gaze, there was a thick killing intent flashing.

The door was hidden, but judging by the scene in front of him, there was a more than 90% chance that there might be a walking corpse in the room, and it might be hidden behind the door.

Facing the situation in front of him, Duan Fei slowly revealed the dagger.

The walking corpse at the beginning of the apocalypse, it has no intelligence, its skills are simple, it is nothing more than looking for smells and sounds, and pounces on living people when it sees them.

This is their weakness, but it is also a fatal existence.

If there was a walking corpse hidden behind the door, when Duan Fei opened the door, the moment it pounced, Duan Fei had a high chance of being directly thrown to the ground, and in the face of such a sudden attack, the dagger was more suitable for counterattacks and hand-to-hand combat.

Duan Fei maintained a high concentration of his mind and slowly pushed the door open.

When the door opened, the imaginary danger did not appear, and what unfolded in front of him was a messy living room.

After slowly pulling out the simple spear he had made, Duan Fei slowly walked inside.

The room was in chaos, tables were overturned, and the floor was littered with fragments of broken coffee tables and porcelain jars. There were no bodies, but a large pool of blood was unusually striking.

Looking along the bloodstains, there was a row of blood-colored footprints that stretched into the bathroom not far away. Duan Fei followed the footprints to the bathroom, and looked carefully through the crack in the door.

The opaque glass door panel was pulled open, and inside a white bathtub, the corpse of a naked male was soaked in blood-stained water.

The corpse had its back to Duan Fei, and he couldn't see his face clearly. However, he noticed that the corpse did not decompose strangely like a walking corpse, so he breathed a sigh of relief, pushed open the door, and walked straight inside.

However, at the moment when Duan Fei had just pushed the door open, his pupils shrank sharply, and his body suddenly retreated.

Just as he stepped into the bathroom, the male corpse suddenly turned over, and his face was completely torn apart, and he couldn't see his true face clearly. There was also a big hole in the stomach, and all the internal organs were eaten empty.

At the same time, at the back of the bathtub, a hideous head was slowly raised.

This is a woman, and the same is the whole body**. It seems that he suddenly turned into a walking corpse while taking a mandarin duck bath with this man. The delicate skin of a baby has now turned into pus-filled and poisonous carrion.

Her face was covered in blood, and her mouth was full of scraps of meat left over from devouring the man, and she looked terrifying.

"Whew!"

The moment she saw Duan Fei, she roared and screamed loudly, let go of the hands that were holding the man tightly, and her whole body popped out of the water directly, rushing towards Duan Fei frantically.

Duan Fei's face remained unchanged, and the spear in his hand stabbed out in a straight line.

"Whew!"

The blade sliced through the carrion, and the sharp tip pierced through the back of her head through her mouth. But even so, she still didn't die, her hands were still waving and struggling.

Duan Fei's face turned cold, and with a twist of her right hand, the blade directly turned half a circle in her mind, forming a parallel shape. Then push hard.

I only heard a "snort", and a large piece of corpse water mixed with red and white ** flew around. The zombie's head was cut in half with a knife.

Not surprisingly, after the head was sliced open, the walking corpse fell to the ground and never got up again.

After killing the walking corpse, the familiar electronic voice sounded again, and the evolution points changed from one to two.

After searching the house and making sure that there were no other walking corpses, Duan Fei stopped staying and hurried to the next house.

The longer he stayed outside, the stronger the smell of sweat and pores on Duan Fei's body became. Although it doesn't look like anything on the surface, the smell is no different from a light in the darkness to the walking corpse.

Therefore, in the action of hunting zombies, Duan Fei's speed must be fast, otherwise, because the smell of sweat and blood on his body attracts a large number of zombies to come, it will be troublesome.

Fortunately, there are only two households on one floor, and it won't take Duan Fei much time to clean up this building, but it still needs to be fast.

"It's a pity that I don't have a gun, and with my marksmanship, dealing with these low-level walking corpses is basically one shot at a time."

Duan Fei sighed secretly in his heart, at the beginning of the apocalypse, when these zombies had not yet evolved to the next stage, the efficiency of hot weapons was much greater than that of cold weapons.

When I opened the door of the other room, unlike the other houses, not only was there no blood in the room in front of me, but even the items were neatly organized, and there was no sign of the walking corpse at all.

Duan Fei was not confused by the scene in front of him, there were only two possibilities for this situation. The first is that the owners of the house are not turned into walking corpses, but survivors. And the second possibility is that everyone in this house was infected by the virus and turned into walking corpses, and there was no situation like Aunt Huang.

Duan Fei held the machete, cautiously walked into the room, and slowly searched.

The contents of the room were surprisingly neat, and there were no of those foul-smelling and disgusting blood spots on the floor.

Looking at the scene in front of him, Duan Fei's body gradually tensed. Because the room is so neat and quiet, the silence makes me feel scared, if there are no survivors, then there must be something else hidden in it.

Duan Fei's guess was not wrong, just as he opened the bedroom door, a black shadow shot out from the room and rushed towards Duan Fei quickly.

At this moment, an instinctive warning of danger made Duan Fei's scalp tingle. Almost without thinking about it, Duan Fei kicked the wall with his right leg, his body tilted and fell backwards, and then he quickly threw away the spear in his hand, and the sharp dagger quickly popped out of his sleeve, stabbing forward with all his might.

"Poof!"

With the sound of the blade piercing the skin, a fishy yellow liquid sprayed from the air in front of it. Then Duan Fei's body fell heavily to the ground, and the black shadow that rushed out of the room also fell weakly from the air to the ground.

After Duan Fei got up, he found out that it was a baby zombie who attacked him.

When he saw the little zombie on the ground, a trace of fear flashed in Duan Fei's heart.

A baby like this who has become a zombie because of a virus doesn't have any particularly powerful combat power in itself, but compared to its combat power, its speed is what makes people really frightening.

Coupled with its unmatched speed and size, when it strikes at you, ordinary people can't react at all, and then whether you are bitten to death or just bitten to death, you are already dead.

When dealing with this baby zombie, in order to prevent the existence of other zombies, Duan Fei deliberately checked the entire room, and there was nothing else except for the two corpses that were found to be eaten in the bedroom.

After the cleanup was completed, Duan Fei continued to clean up to the bottom of the floor.

Tenth floor.

Ninth floor.

Eighth floor.

……

It took most of the day for Duan Fei to clean up all the floors. However, Duan Fei found no survivors, and even if they were infected by the virus, they were all eaten by the walking corpses.

This discovery made Duan Fei feel a little surprised, after all, there was not a single survivor on the entire floor, except for himself and his sister, so the probability was a little too small.

However, Duan Fei didn't pay much attention to such an anomaly, as long as he was out of this level, there would definitely be survivors.

After seven days, about one-tenth of the walking corpses will mutate, giving birth to wisdom and various special powers. At that time, the only survivors will have a more difficult environment to survive, and it will be even more difficult to find other survivors.

At this time, God seems to have given up on humanity. Compared to the walking corpse and the alien beasts, the number of humans who can awaken and obtain abilities is pitiful. In the face of an almost endless stream of mutated zombies and alien beasts, humanity has lost its absolute hegemony and has become the weakest race.

However, these things are still too far away for Duan Fei for the time being. His only task at the moment is to survive the seven days of the apocalypse safely.

The evolution system gave Duan Fei the ability to survive and grow stronger, and it also provided a guarantee for him to hunt down mutant walking corpses seven days later. Seven days is enough time for Duan Fei to gain a certain number of evolution points, and when the time comes, he will definitely usher in a comprehensive evolution.

Unconsciously, time passed slowly, and the time spent cleaning the floor was much more than Duan Fei had planned, so when he got home, it was already four o'clock in the afternoon.

With a click, the door opened. Duan Xinyue came to the door in a wheelchair, with red eyes, punched Duan Fei hard, and then threw herself directly into his arms.

"You bastard, I'll let you come back before twelve, you see what time it is!" Duan Xinyue scolded angrily, crying.

Looking at Duan Xinyue's nervous and worried expression, Duan Fei gently touched her head and comforted her guiltily: "I'm sorry, I was wrong, I promise to go home on time next time!"

"Next time I do something like this, I will never spare you!" Duan Xinyue said viciously.

Duan Fei nodded, and then hurriedly accompanied her back to the house.

In fact, all of Duan Fei's actions were planned, the danger had been minimized, and there was nothing to worry about, but he still ignored Duan Xinyue's mood after all.

Duan Fei secretly decided in his heart that before the next operation, he would definitely take his sister into account and not let her worry about being scared like this all day!
