I'm back from hell

"puff."

"puff."

……

No. 7 was still swinging the ax crazily, and his whole person was in a state of excitement and anger.

Xia Yu did not stop, but stabbed the butterfly knife into her sister's heart.

"Om."

Suddenly, the spiritual energy of heaven and earth in the air poured into the blade of the butterfly knife crazily, and my sister's heart withered at a speed visible to the naked eye.

Xia Yu knew that this was the spiritual heart cooperating with the spiritual energy of heaven and earth to temper the butterfly knife in all directions.

As for what level it can be promoted to, it depends on the psychic heart.

Not all weapons can be tempered by the psychic heart, not thermal weapons. If the material of the weapon itself is very high-grade, ordinary psychic hearts cannot temper it.

At the moment, the butterfly knife in Xia Yu's hand is just a playful knife purchased for tens of dollars. The material is very rubbish, and even the lowest level of psychic heart can temper it.

Just over ten seconds.

The movement disappeared.

My sister's heart is also completely withered.

Xia Yu pulled out the butterfly knife. The blade was all pink, as if it had a sticker on it. It was tender and cute. She flicked her jade fingers, and the blade trembled slightly. It could be seen just from the vibrato and the frequency and amplitude of the trembling of the blade. Compared with It's at least a step up from before.

The most important thing is that after being tempered by the spiritual energy of heaven and earth, it can hurt spiritual life!

"Psychic Heart."

"Sure enough."

She looked satisfied.

If she encounters that 'asexual ghost' again now, she will be sure to protect herself without using the crystal core.

This operation was so smooth that Xia Yu became more vigilant. She immediately calmed down and strode towards No. 7, who was tired from cutting and was sitting on the ground with a dull look on her face.

"Pfft."

A knife penetrated the brother's heart.

As for the head that was chopped into paste, she just glanced at it and then looked away without changing her expression, because this kind of situation is too common in the end of the world.

got used to.

"vomit."

Xie Shaokun vomited again.

Last time, he could spit out water, but this time he could only retching.

Xia Yu glanced back and said calmly: "There is not much time left for you to adapt. I don't want you to hide behind and use your powers all the time."

Xie Shaokun's retching sound disappeared instantly, and he chose to endure it.

How can a grown man be looked down upon by a woman?

Xia Yu focused on No. 7, and a strange color flashed in her beautiful eyes: "This woman's absorption speed of spiritual energy is really amazing, she is not slower than me."

You know, she used the ancient guidance technique!

This is talent!

After three seconds.

The younger brother's psychic heart has completely withered, and the quality of the butterfly knife has only improved by half a level. The pink color of the blade gradually transitions to blood red.

In addition to the higher the quality, the more difficult it is to upgrade, there is another reason: the younger brother's psychic heart is much lower in level than his sister's psychic heart.

"Walk."

Xia Yu got up and returned to the monitoring room to find the precise location of the last long-tongued monster.

Xie Shaokun hurriedly followed, while No. 7 was left alone.

Xia Yu didn't try to conquer No. 7. It was tiring to carry a novice like Xie Shaokun in the apocalypse, let alone two of them?

If No. 7 can survive to the end, let’s talk about other things.

And shortly after the two left, No. 7 felt that someone was watching her secretly. She had become extremely sensitive because she had stayed in the white building for a long time, so even though she was overly sad and her mentality collapsed at this moment, she still had it immediately. He noticed it and looked over subconsciously.

However, I saw nothing.

"Roar."

At this moment, a mutant smelled the smell of blood and rushed down from the negative level.

No. 7 looked at the clothes the other party was wearing and knew that she was following Brother Li's men during her lifetime. Madness and hatred flashed in her eyes, she picked up the fire ax and launched a charge.

She seemed to be unaware of the pain. She didn't care at all about the blood marks left by the mutants on her body, and didn't care about the flesh and blood being torn off her body. She only knew how to attack.

In the end, she actually killed a mutant.

No. 7 went completely crazy, slashing wildly, crying and laughing at the same time, and said some strange words: "You damn devils all deserve to die, you all deserve to die."

"Don't touch me, wuwu... I'm so dirty, so dirty."

"Please don't hit me. I was wrong. I won't run away. I won't run away anymore."

"Killed! I killed! Don't come to me. I didn't mean it. They forced me. They forced me."

"I am a demon."

"We are all demons, let's go to hell together, go to hell, haha..."

the other side.

"Dong dong dong."

Xie Shaokun knocked on the door of the monitoring room.

Three times.

Six strokes.

No one opened the door.

"Manager Ma won't die inside, right?"

He frowned.

"Do not."

Xia Yu raised her head, looked at the surveillance camera, and said calmly: "He is still alive, he just wants us to die."

Manager Ma in the monitoring room felt Xia Yu staring at him. He was startled and accidentally touched the chair, making a noise.

Hearing the sound, Xie Shaokun immediately gritted his teeth and shouted: "Manager Ma, you son of a bitch, open the door for me."

"Otherwise I'll kill you."

Manager Ma realized that he had been exposed, so he stopped pretending and shouted: "This door is made of pure steel and is stronger than a security door. No matter how powerful you are, you can't break in."

"Shout as hard as you can, it's best to attract more monsters, and then you will all be eaten by them."

"haha a……"

Feeling the pleasure of revenge, he accidentally pulled the injury on his lip and screamed in pain.

Xie Shaokun was so angry that he wanted to kick the door down.

Xia Yu said calmly: "Save your energy and go deal with the mutants."

"I'll open the door."

As she spoke, she threw the butterfly knife at the other party.

Xie Shaokun hurriedly took it, and then saw Xia Yu squatting down and starting to unlock it, with a confused look on his face.

Can sister also pick locks?

What did you do before?

"Roar."

At the end of the corridor, a mutant appeared again. After discovering Xia Yu and Xie Shaokun, it launched a charge.

"This... I will fight with you."

Xie Shaokun gritted his teeth and rushed forward with the butterfly knife in hand.

He had already seen that the mutant's vital part was on his head, and that the mutant had no brains. He also knew that his fighting style was of little use, because the mutant did not know pain.

Thinking of Xia Yu's neat battle scenes, he quickly arranged a series of battle moves and plans in his mind.

then……

"Boom."

The mutant was too fast and kicked him away.

"Cough cough."

Xie Shaokun felt like his stomach was about to be kicked through. He coughed crazily and couldn't straighten up in pain.

Fortunately, he was used to fighting bravely and hurting the opponent even when he was injured, so he swung the butterfly knife in time when he was kicked away.

Injured the mutant's ankle.

After being tempered and strengthened, the butterfly knife can be said to be cutting iron into clay.

It was easy to cut off most of the mutant's ankle, leaving only the thumb-thick part connected to the calf.

"thump."

Just as the mutant was about to continue attacking, its feet were completely free, it stumbled, grabbed the ground with its head, and lay down in front of Xie Shaokun.

Seeing this, Xie Shaokun was overjoyed. He endured the pain and stabbed out the butterfly knife again.

Hit the opponent in the back of the head.

Most of the butterfly knife was submerged in it. If his hand hadn't been holding the handle of the knife, the handle would have been submerged as well.

died?

Looking at the motionless mutant, Xie Shaokun was so excited that he suddenly turned his head to show off: "Sister, I..."

The sound froze.

He saw Sister Yu leaning on the door frame, with her hands folded across her chest, calmly looking down at herself lying on the ground in an extremely embarrassed state.

Xia Yu said calmly: "Is this the martial arts you borrowed 10 yuan to learn?"

Xie Shaokun was so embarrassed that he wanted to dig out a large flat floor with six bedrooms, two living rooms, a kitchen and three bathrooms on the ground with his toes.

"Check to see if there are crystal nuclei. If not, come in quickly."

After saying that, Xia Yu walked into the room and his eyes fell on Manager Ma, who was already kneeling in front of him, shivering.

"Grandma."
