The so-called experience value is actually a special kind of energy, and the amount of value also represents the amount of energy.

Killing a target will give you 4 experience points, which is not a small amount, which shows that that thing is very powerful.

But what was the mutant just now, so weird that it could unleash a strange shadow attack after death?

"Nuwa, what was that thing just now?" Hong Yi immediately asked.

"A special kind of energy, in layman's terms, is the ghosts and souls recorded in human classics, that energy just now wanted to control you, but failed, normal human beings, should not be possessed by that kind of energy, so don't worry." Nuwa replied.

Hong Yi breathed a sigh of relief, he was really afraid that those ghosts could hurt people or parasitize into people's bodies, if that was the case, these mutants would be difficult to deal with.

But since normal humans don't get possessed, there's no need to worry.

Compared to Hong Yi, who easily killed an enemy with a flaming arrow, on the other side, whether it was Yanfang or those barbarian warriors, they were all in a bitter battle at this moment.

These strange 'mutant' humans are obviously not afraid of pain, they are fast, they are infinitely powerful, and the smoke fart is okay, those mutated humans are not the opponents of the smoke fart at all, but the barbarian warriors are a little passive, there are quite a few of these mutant races, there are more than a dozen, and they rushed over together, and they almost knocked down several shield-wielding warriors, even if they were pierced through the body by sharp spears, they did not die.

"Nuwa, you come to record the illustrated book, these mutant humans should be some kind of new mutants, especially the special ghost energy that appears in their bodies after death." Hong Yi spoke, took out the Night Blade, which was blessed with biological fire energy, and directly rushed up to melee with these mutants.

Hong Yi found that these mutants were more afraid of fire, so using energy arrows or flaming arrows would consume more biological energy, while using the Night Blade would save a lot of biological energy, and they would generally be ignited immediately when touched by flames, as if they were drenched with a layer of oil.

In a blink of an eye. There was a mutant human who died under Hong Yi's night blade, and a strange black shadow appeared on the body of the mutant human who was killed.

This time, Hong Yi saw it clearly, it was a ghost-like thing, and it looked very terrifying. After flying out, he didn't rush towards Hong Yi, but at a barbarian warrior and entered his body.

The barbarian warrior only stiffened his body for a moment and quickly returned to normal. It seems that there is nothing wrong with it, and sure enough, as Nuwa analyzed, these 'ghosts' pose no threat to them.

At that moment, Hong Yi didn't spare his hand anymore and began to kill these mutant humans with all his might.

Now his melee ability is also remarkable, leopard step, assassination, leopard step, assassination, and stabbing by the flaming blade of the night. Those mutant humans screamed one by one and turned into a charred corpse, and more than a dozen mutated humans, Hong Yi killed them all in less than a minute.

Although the smoke fart does not have the ability to use flames, its size, strength and sharp minions still occupy an absolute advantage, although the body defense of the mutant human is strong, but it is also limited, and if it is hit head-on by the smoke fart, it will immediately fall apart.

In a short time, all mutant humans were wiped out. The strange ghosts that emerged from their corpses did not rush again, but scattered and flew away.

"Thank you Shingod for your protection!"

The barbarian warriors spoke out together at the moment.

Hong Yi nodded, and asked them to prepare some torches, although the shelter was opened smoothly. But the situation inside is still unknown, maybe the lighting system has failed, and in order to deal with those terrifying mutants, torches must be prepared.

Lao Chen and the others moved quickly, and after a while, they got dozens of torches and lit them. Enter the passage with Hong Yi.

The passage is straight forward, on both sides are some glass rooms, there are some equipment in it, but at the moment there is not a single figure to see, further ahead, there is an elevator entrance, but the elevator has long been out of energy, has been abandoned.

"Nuwa, is there a structural diagram of Vault 30?" Hong Yi looked around and asked out loud.

"Yes, I suggest going directly to the main control room and obtaining the highest authority from the Vault, which is equivalent to taking control of this place, and the current situation is likely to be that the main energy system fails, as long as the backup energy system is activated, the operation of this Vault can be restored." After Nuwa finished speaking, a structural diagram appeared at the same time, and a point of light was marked in the upper area, which was the main control room.

Hong Yi looked at it, the main control room was in the center of the fourth basement floor, and the emergency passage was only more than 200 meters away, and on the map, Hong Yi saw the logo of the arsenal, which was on the basement floor.

Turning his head to look at Lao Chen's gang, Hong Yi felt that it was better to get some guns for these people first, but if the energy was not restored, maybe the door lock could not be opened.

There are four floors underground, and the situation is unknown, but you know that you will encounter some trouble with your toes, and it will definitely not be so easy to take Lao Chen and them down.

In addition, another problem is that because of the size of the emergency passage, I am afraid that it will not be able to pass through the physique of the smoke fart, so the smoke fart cannot go down, so it is better to let them all stay on this floor and stand by.

Thinking of this, Hong Yi ordered them to stay in place here, at least it seemed safe here, and even if there was trouble, they would definitely be able to deal with it with dozens of soldiers and smoke farts.

Lao Chen and the others also know that it is dangerous here, but it is safe to stay here, of course they agree.

Finding the entrance of the emergency passage, Hong Yi gave the order to Yanfart, pushed open the door and walked down alone.

The emergency passage is the staircase, which is dark at the moment, even the emergency lights have already been extinguished at this moment, fortunately, Hong Yi has the adjutant's brain and can switch to night vision mode, but even so, he can only see the situation within five or six meters.

Walking down two floors, Hong Yi couldn't hear any sound from above, including the low roar of smoke farts, it was extremely quiet, and the air was also very unpleasant, full of all kinds of rancid smells, but not so much that it was suffocating.

In the staircase passage, Hong Yi found some bones.

These people obviously didn't know how long they had been dead, and the bones were only bones, and after looking down, Hong Yi could be sure that these bones had been eaten.

What was eating these corpses, and Hong Yi's mind came up with those mutant species before, maybe they were them.

Hong Yi did not stay or check on the other floors, but directly entered the fourth underground floor, and then pushed the door and walked out, the silent space, any small sound will be extremely harsh, even if Hong Yi has been prepared for a long time, and he himself has strong strength, but he is still a little nervous.

It's a psychological effect, and it's the same for everyone.

In the holographic vision, Hong Yi saw that he was not far from the main control room, and he could reach it by walking more than fifty meters further.

But at this moment, Hong Yi stopped, because in the dark, several figures slowly appeared, surrounding Hong Yi, these figures moved extremely fast and silently, but Hong Yi still found them.

A figure is only four meters away from Hong Yi's side, and at this distance, Hong Yi can clearly see its appearance.

Sure enough, it's the same as those mutants before it.

Hong Yi saw the enemy, but calmed down, sometimes, not afraid of the enemy appearing, afraid that they will not appear, only the unknown, will produce fear, anything that visits the bright side, is not worth fearing.

With a snort, the night blade held in Hong Yi's hand turned red, emitting a dazzling light in the darkness, like a red-hot soldering iron, surrounded by flames, illuminating the surrounding area.

The mutants immediately screamed and attacked.

Their strength and speed have already exceeded half of the White Star Level 2 Mutants, and if they were other White Star Level 3 Evolvers, they would definitely be in a hurry, and even capsize in the gutter.

However, because Hong Yi has the physique bonuses of the two major skill trees of Hunter and Shadow Walker, his real strength has long surpassed the fourth level of White Star, plus the White Blade Assassination and the Night Blade, the final result is that these mutant races that attacked Hong Yi are all wiped out.

The burning corpse became the best light source, illuminating the originally dark fourth layer a little, and also allowing Hong Yi to see the situation here.

There is a long corridor in front, there are many rooms on both sides, but the doors of all the rooms are closed, and an iron door in front of it is the entrance to the main control room.

Soon, under Nuwa's instructions, Hong Yi opened the door of the main control room, which was filled with various equipment, a large monitoring console, with dozens of monitoring screens placed in a 180-degree direction, and on the console, it was densely packed with various buttons.

Obviously, though, most of the lights are off.

In a computer room behind the main control room, Hong Yi manually switched the energy system to backup energy, and the next moment, Hong Yi heard a sound of the machine starting, and then the light on the ceiling flashed a few times and turned on.

Power was restored not only to the main control room, but to the entire Vault Thirty, including all surveillance cameras and electronically controlled metal doors.

The first thing Hong Yi did was to close the door to the shelter, which would prevent the mutants from outside from finding and entering, and it would take time for Hong Yi to clean up the place.

"Congratulations, the power of the shelter has been restored, but you still need to modify the management permissions of the main control system, this is left to me, I want to upload some data to the main system here, but you need to connect your brain to the system here." Nuwa said at this time.

It's just that Hong Yi didn't move, but asked very seriously: "Nuwa, tell me the truth, what is your idea for instigating me to come here, if you don't tell me, I won't connect the brain to the main system!" (To be continued.) )
