I used the return system to raise the whole demon world

No one thought that this place would be a scientific research center.

But why are there so many people in the scientific research center?
Judging from the clothes of the zombies we solved earlier, those people were obviously not scientific researchers.

Doubts spread in her heart. Su Man thought for a long time but couldn't figure out what was going on, so she simply stopped thinking about it.

The office building was locked from the inside. Several people entered the main building. The clean inside made people feel like they were back before the end of the world.

After searching around the building and finding nothing special, several people prepared to leave.

When the people walked away, a figure stood out on the roof of the side building of the office building, looking at the five people leaving from a distance, not knowing what they were thinking.

On the way back, the five of them were not prepared to continue hunting monsters and corpses because of their previous gains, so they returned to Ahu's base camp after a while.

"Sister." Aguai was the first to step forward when he saw Su Man and hugged Su Man.

"Ah Guai misses my sister so much. Next time my sister goes out, how about taking Ah Guai with her?"

Su Man has completely adapted to being coquettishly hugged by a tough guy who is nearly 1.9 meters tall.

She stretched out her hand to hug the man back out of habit, and patted him twice on the back.

"Ah Guai is still young. When Ah Guai grows up, my sister will take you to fight monsters together."

"Ah Guai is already ten years old, not too young."

As soon as she finished speaking, Su Man felt the man's furry head nuzzling her neck.

It felt a bit itchy, so Su Man pushed her large canine brother away calmly.

Several people on the side were not surprised by this. Only Jun Shang's eyes flashed and he wanted to say something, but didn't.

Su Man pulled Aguai to sit down by the bed, motioned Jun Shang and the others to rest, and then took out the trophies in her pocket.

Qin Jinnan held the three secondary healing crystal cores in his hand, his whole face flushed with excitement.

"Sister Su, is this for me? Can I really use it?"

"It's okay if you don't want to." Su Man looked at him and teased.

Qin Jinnan immediately took back his hand, "If you want it, how can you take back what you gave me! Sister Su is the best."

Chen Yuan on the side looked at Qin Jinnan with envy, and saw Su Man handing him two crystal stones, which were also rare gold.

"The gold one, take it."

Chen Yuan took the crystal core, pursed his lips and glanced at Su Man. He wanted to say thank you but felt too unfamiliar.

"Sister Man, don't worry, I will work hard to improve my strength to protect you."

"That's not necessary, as long as you can protect yourself."

Although Su Man's words were a bit heartbreaking, Shen Yuan knew it was the truth, but so what if he was not as powerful as Sister Man?
At the critical moment, he can risk his life for Sister Man!

As long as he knows it in his heart.

After Shen Yuan and Qin Jinnan went to their beds to start absorbing the crystal cores, Su Man was going to take a shower at her usual place.

As soon as the person arrived at an empty house and was about to close the door, he saw a pair of hands blocking the door.

"Why are you here?" Su Man looked at Aguai in front of her.

"Sister, I have something to tell you."

Su Man looked at the serious expression of the man in front of her, stepped aside, and closed the door after Ah Guai also entered the room.

"Tell me." In fact, she was quite curious about what the other party was going to say. Could it be that he had regained his IQ and wanted to ask for an explanation?
After all, I have been with the other party's mother for a long time.

"Why did sister bring gifts to them but not to Aguai? Is it because Aguai is disobedient and sister doesn't like Aguai?"

Su Man was a little embarrassed when she heard this. How should she respond? What kind of crystal core did he want for a fool?
But facing the opponent's injured deer-like eyes, Su Man couldn't bear it, feeling as if she was bullying a child.

"Of course not. My sister likes Ah Guai the most, but Ah Guai is still young, so it's useless to give her the crystal core."

"Sister is lying! Xiao Nan is much younger than Ah Guai! But Xiao Nan has gifts, but Ah Guai doesn't!"

Su Man choked on words, and sometimes being reasonable makes people angry.

Seeing that Su Man stopped talking, the man thought he was right and felt even sadder.

"Sister is really a liar? They said Aguai is a fool and a burden to sister. Doesn't sister want Aguai?"

Su Man's originally somewhat helpless expression suddenly became sharp with the man's words.

"Who said you are a fool?"

"That's what the bad woman said."

Su Man: "Ah Guai, tell sister, who is the bad woman you are talking about? Where did Ah Guai meet her? What else did she say to Ah Guai?"

The man seemed to feel Su Man's suppressed anger. He thought Su Man was angry with him, and the expression on his face became even more aggrieved.

"Sister, Aguai is not a fool. Aguai is smarter than Xiaonan! When Aguai grows up, he will be able to protect his sister. Sister, don't let Aguai go."

Su Man listened to his choked voice, feeling distressed and angry at the same time. What kind of arrogant bastard dared to talk nonsense and let her know that he had to skin her!

A figure suddenly flashed in her mind. Su Man tentatively described the person's appearance. When Ah Guai nodded, she understood instantly.

This woman, if she doesn't cause trouble for her, even if she doesn't offer incense and worship Buddha, she still dares to gossip behind her back!

"Our Aguai is not stupid at all. Don't listen to other people's nonsense in the future. Come to my sister's place and there are crystal cores for Aguai to play with."

Su Man was tired of coaxing her child, so she casually took out all the crystals in the space bracelet.

"Sister, there are many more. I can take whatever you like."

As soon as she finished speaking, she saw the man pick up a black crystal stone the size of a fist.

Su Man was speechless, why did she take out the fourth-level space crystal stone?

This man didn't know if he was really stupid or not, but he picked the best one at once. When Su Man opened her mouth to say that this was not possible, the man was already looking at her with a raised face.

"Sister, I would like this one. This one is the biggest. I like the big one."

Haha, she likes big ones too.

She reached out to take it back when she saw the man curled his lips and looked at her in disbelief.

"Isn't sister reluctant to give it to Ah Guai? Sure enough, sister doesn't like Ah Guai, right?"

Su Man's stretched out hand froze. Forget it, what are you trying to grab with a child? Once he has had enough fun, he won't care about it anymore. It will still be his own, just use it a few days later.

"I told you not to think too much. If you like it, go ahead and play with it. If one is not enough, get more."

Su Man said and grabbed a handful of first-level crystal cores and stuffed them into the man's pocket.

Humph, you are a child~ You don’t cherish things when you have too much. She believes that the crystal core will be back in her hands in a few days.

The corners of the man's mouth were raised when he smiled at the fact that his pocket was full of crystal cores.

During the day, he saw Shen Yuan and Qin Jinnan practicing with crystal stones, and he had long been envious. He still remembered that Su Man had given him a crystal before, and he absorbed it all that day. At that time, his IQ was only three years old, not Understand the purpose of crystal nuclei.

But in the past few days, every day when he woke up, he could feel that he understood more and more things. Now he clearly knew that he was also what everyone called the awakened one.

And his powers are fire and thunder.

He doesn't remember who he is, he only remembers that his sister has been protecting him, but he is not the only brother his sister has. He doesn't like his sister being nice to others. He must practice hard, grow up as soon as possible, and be as strong as his sister!

No, he is stronger than his sister, so he can protect her from now on.

After coaxing the giant baby, Su Man breathed a sigh of relief and secretly lamented that she had already adapted to the difficulty of raising a baby before she found her biological son.

"When you're not angry, go back and rest. Sister, go back after taking a shower."

The man was not happy to be pushed out by Su Man. When Su Man said he wanted to take a shower, he immediately stopped.

"Sister, Aguai also wants to take a bath."

He remembered that his sister had helped him take bath before. Her sister had powerful water powers, and he also wanted to sleep cleanly.

Su Man's hand on the man's back froze.

Although she has adapted to the occasional intimate contact from men, the premise is that she keeps telling herself how old she is!God knows what she went through the first few times she helped Aguai bathe.

This man has eight-pack abs!

Anyone who looks at that body of tendon meat can’t help but want to get wet!
But facing those ignorant and clear black eyes, her complicated thoughts seemed a little dirty.

Su Man gritted her teeth, this kind of thankless job was torturing herself.

"No, I'm obedient. If you want to take a bath, I'll let Shen Yuan take you there."

Ah Guai still stood still.

He didn't want Shen Yuan to take him to take a shower, he just liked his sister to help him take a shower.

The two were in a stalemate for a while. Su Man didn't want to waste time, but finally compromised.

Anyway, she won't suffer any loss, and she won't see anything in vain!
Of course, using superpowers to take a shower wouldn't waste time. A few minutes later, Su Man pushed the man in new clothes out of the door. This time, nothing worked.

She still has to wash herself!
Aguai, who was pushed out of the door, had a happy smile on his face. He felt relaxed after taking a bath and was naturally in a happy mood.

But as soon as he went out, he saw a figure standing a few meters away. He didn't know how long he had been standing there. His faint eyes fell on Aguai. Aguai couldn't understand his expression, but she just didn't like him for some reason.

"Where's she?" Jun Shang's face didn't look good. This wasn't the first time he saw two people entering a room alone since he followed Su Man. Thinking of what just happened, he couldn't control his discomfort.

He had known for a long time that Su Man had a son and a man, so he was unable to fight for anything. He just wanted to follow her silently and watch over her.

But this doesn't mean that he can accept another man taking advantage of Su Man.

Ah Guai didn't like the way Jun Shang looked at her. The man's dislike of her was too obvious. Although he didn't understand why, it didn't mean that he had to passively accept it.

Oh, you don’t like me, and I don’t like you yet!
Don't think I don't know you want to steal your sister from me!

Aguai was thinking in his heart, and said even more unforgivingly: "Sister is taking a bath, do you have anything to do with her?"

Upon hearing Ah Guai's provocation, the veins on Jun Shang's forehead tightened. He clenched his fists and resisted the urge to beat up the man in front of him.

He told himself not to be angry, he was a fool and should not be impulsive.

"She is your sister, a woman, and you are a man. You can't follow her when she comes out to take a bath in the future. It won't be good for her if others see her."

Jun Shang tried his best not to speak too harshly, but Ah Guai still heard his anger.

"But Aguai also needs to take a bath, and my sister will help Aguai wash it."

Ah Guai felt that there was something wrong with this man. How could he take a bath if he didn't follow his sister?

If he doesn't take a bath, he will become smelly. Not to mention his sister, even he himself doesn't like the smell.

Jun Shang almost spit out a mouthful of blood when he heard Ah Guai's words. If he hadn't known that the other person was a fool, he would have suspected that the other person was showing off to him!
Why does Su Man want to help him take a bath?
Why?
Are you just stupid?

"You are a man, and a man should take a bath by himself. If you ask others to help you wash it, it shows that you are a child who has not grown up. Only children will let adults help you take a bath."

Ah Guai was a little panicked when he heard this.

"Ah Guai is not a child, Xiao Nan is a child. My sister said that Ah Guai will grow up tomorrow and grow up every day. Ah Guai is a man, not a child!"

Seeing that he was excited, Jun Shang vented most of his anger. He was also stupid, quarreling with a fool here.

"." He glanced at Ah Guai one last time with a complicated expression, and turned around to leave.

At this moment, Aguai suddenly took out a bunch of crystal nuclei from his pocket.

"Aguai can also practice. When Aguai becomes more powerful, he can protect his sister. Aguai is a man, not a child!"

Jun Shang ignored what he said about being able to practice and treated it as nonsense.

She stared at the level [-] black space crystal core with frowning eyes, unable to believe that Su Man actually gave it to this fool.

"Why is it here with you?"

"My sister gave it to me to play with."

Jun Shang had seen Su Man collect things with his own eyes, so he always thought that Su Man had space system powers. Such a rare fourth-level space system crystal core, Su Man, did not use it himself but was played with by a fool. The more he thought about it, the more uncomfortable he became.

He knew that Shen Yuan was also from the space system. Even if Su Man didn't use it, it would be better to give it to Shen Yuan than to let a fool use it as a toy. So Su Man actually cared about this fool?

Reaching this conclusion, Jun Shang felt even more uncomfortable.

He glared at Ah Guai fiercely, turned around and left.

When Ah Guai was the only one left in the corridor, he stood with his lips pursed for a long time, thinking about whether to tell his sister about Jun Shang's bullying of him and let her help him vent his anger, but complaining like this seemed to make him look like a child.

He didn't want his sister to think that he hadn't grown up, so in the end he could only go back to the dormitory with his head hanging down.

When he entered the room, he forgot to show off the crystal core he had obtained to Shen Yuan and Qin Jinnan. He lay on the bed and covered himself with a quilt. Under the quilt, he held the primary crystal core in his left hand and the black crystal core in his right hand. He wanted to practice and change. powerful!
The energy of the primary crystal core poured into the body instantly, and the body was like a door being opened. Before it was closed, another unfamiliar energy rushed in immediately.

The energy of the fourth-level crystal core is overwhelming.

Ah Guai was in so much pain that before she could even cry out, she felt a sweet sensation in her throat and fainted.

When Su Man came back, Shen Yuan and Qin Jinnan were both practicing. Aguai looked like he was asleep. She didn't disturb the three of them and started to absorb the crystal core while lying on the bed.

It's just a bit pitiful that she absorbed primary crystal nuclei.

Holding the primary crystal core in her hand, one was absorbed in a moment. She wordlessly took out a bunch of primary crystal cores in the space and threw them into the bed. She held them close to herself and continued to absorb them with the mentality of being better than nothing. Unknowingly, Feeling asleep.

What Su Man didn't know was that she didn't stop absorbing it while she was asleep. Hundreds of crystal nuclei formed a small vortex around her, and energy invisible to the naked eye was sucked into the vortex.

Aguai is in crisis on the side.

Normal people cannot absorb crystal nuclei across superpowers, and it is even impossible for a primary-level superpower to directly absorb a fourth-level crystal nucleus. By some strange combination of circumstances, he actually absorbed a primary crystal nucleus and a fourth-level crystal nucleus that was not of his own type at the same time. Energy gathered along the limbs and bones toward the mind.

If the Dantian in the world of cultivation is the source of cultivation, then the Dantian in the apocalypse is the human brain.

Just like crystal nuclei appear in the minds of zombies, a strange space is also created in the human brain under the influence of supernatural powers.

At this moment, in Aguai's mind, two small dots, one red and one purple, slowly grew bigger. Suddenly black energy poured in, breaking through the two dots in one go. The three energies merged and fought, making it a great time.

But the red energy and purple energy soon became no match for the black energy. Seeing the black energy gaining the upper hand, the originally stable mind suddenly became unstable.

The black energy seems to have realized how powerful it is, and wants to swallow up the red and purple.

Naturally, Red and Purple would not be willing to be swallowed up and began to fight back.

The energy space in Ah Guai's mind was getting bigger and bigger due to the noise caused by the three of them, like an inflated ball.

The pain that felt like his brain was being torn apart made Aguai's whole body turn red, and his eyes, ears, mouth and nose were bleeding.

Just when it seemed that the person could no longer hold on, the energy vortex on Su Man's side began to absorb energy like a powerful predator.

Almost instantly, the black energy that had a strong position in Ah Guai's mind was attracted by the vortex and dissipated most of it.

The energy in my mind was no longer turbulent and slowly calmed down.

On the other side, Su Man felt so comfortable from the sudden inhalation of energy.

She felt like a fish swimming in the water, not enough, not enough, she wanted more energy.

Unfortunately, the energy suddenly disappeared.

She was so alert that she sat up immediately.

When he turned around, he found Shen Yuan and Qin Jinnan not far away, standing anxiously beside Aguai's bed.

"what happened?"

"Sister Su, look quickly, I'm bleeding."

When Su Man heard this, she immediately jumped out of bed and walked over. She was shocked when she saw Ah Guai with blood on his face. A water power washed his face clean. Su Man then carefully checked Ah Guai's nose to confirm. She was relieved to be alive.

The hand moved to Ah Guai's forehead again. There was no fever. What was going on?

She reached out to feel Aguai's pulse. She was in good health and not sick.

Just when she was confused, the hand that was still on Aguai's wrist was suddenly held.

Su Man lowered her head and met a pair of deep eyes.

"Are you awake? How do you feel? Are you feeling uncomfortable anywhere?"
