Taboo Manual for Raising a Succubus Girlfriend!

The houses were burning, and in the thick black smoke, the old man was choking and coughing, his aged legs could no longer keep up with the others. The children had never seen such a hellish scene and could not bear it and burst into tears.

If you continue like this, you will die.

They will be discovered by the black monsters with guns and killed mercilessly.

Perhaps, if we let the young people go on their own and leave the old people and children behind, we might not be wiped out.

Everyone knows this, but...

I can't do it.

There is a connection between them, a connection called family.

It is impossible to leave the most important family members in hell and abandon them, even if it means death.

But...

At the corner of the alley, something terrible happened...

「Click」

The cold muzzle of the gun was pointed at the group of unarmed refugees.

Amidst the cries of despair, the demons hugged their families, waiting for the god of death to swing his scythe.

The mechanical soldiers watched them silently. This emotionless weapon had no idea what emotion was and could pull the trigger without hesitation.

“Bang, bang, bang—”

Flames burst forth.

Another sinful blood flower is about to bloom in the demon world.

but..

An accident happened.

As the bullet spiraled forward, it seemed to hit a transparent wall and was instantly bounced off, creating waves of ripples in the air. The copper-colored bullet head rolled to the ground with a crisp sound.

"The shelter is over there, hurry over there!"

From the other side of the alley, a young girl's childish and hurried voice came.

She slowly raised her hand and used a magical barrier to protect the demons. The flickering firelight illuminated her cherry-colored pupils, and her light pink twintails swayed gently.

It’s Yuyi.

She used a magic barrier to protect the trapped demons and helped them escape.

The demons who escaped death did as they were told. They moved quickly in the direction Yu Yi pointed, but the mechanical soldiers seemed unwilling to let them go.

"Hinder—"

Facing the petite demon girl in front of it and the strange magic barrier, it didn't hesitate at all. It switched the gun to grenade launch mode and fired directly at Yu Yi.

“BOOM—!”

Flames and explosions rose instantly.

“Nyaaaaaaaa…?! W-What the hell is this, fireball magic?!”

The grenade was blocked by Yu Yi's magic barrier, but the huge flame impact still made her stagger back two steps, and the scorching heat wave increased the temperature around her.

Seeing that the attack was effective, the mechanical soldier quickly reloaded and prepared for another shot.

but...

Before it noticed, a cold shadow had come to its side in the burning flames.

"Stop it."

Before the cold voice reached his ears, a pitch-black blade had already cut through space.

The mechanical soldier was stunned.

A woman with wolf ears appeared before him, her blood-red eyes staring closely at it, her hair even darker than the shadow's.

"Danger...."

By the time the alarm in its body started to sound, its sight had already shifted, its body had been cleanly cut in half, and the gem in its chest had been completely shattered.

"Boom!"

As if to vent his anger, after the mechanical soldier lost its power, Ye Si stomped on its head and crushed it. After giving it a cold and contemptuous look, he turned and went to Yu Yi's side.

"Are you okay?"

After arriving at his lover's side, Ye Shi asked with a little uneasiness.

"No, it's okay, I was just a little scared..."

Yu Yi shook her head, dusted herself off, and jumped twice on the spot to indicate that there was no problem.

"That's good..."

Ye Shi felt relieved for the time being, but the expression on his face was still complicated.

Now, the demon world has fallen, and she and Yu Yi are both drawn into the war, which is the last thing she wants to happen.

Everything that had been done before to prevent the war seemed to be meaningless.

"I'm sorry, Yoshito..."

Yu Yi noticed the uneasiness in Ye Shi's eyes, intertwined her fingers in front of her chest, lowered her head and said apologetically:

"It's all my fault for being so willful. I had to go back to such a dangerous place and made you worry..."

Before entering the city, they had a choice.

Looking at the burning Goodnight City, they can choose to turn around and leave, live in seclusion in the mountains, and temporarily avoid the smoke of war.

Or like now, risk going back to the city and find a way to do something.

Yu Yi chose the latter.

She couldn't just watch the city that raised her burn down. There were so many precious memories, important friends, a warm home, welcoming neighbors, and the school that educated her. All of these were engulfed in flames.

No matter what, she wanted to do something, even if it was just a drop in the bucket, otherwise she would regret it for the rest of her life.

"I understand that feeling..."

Ye Shi patted her head and replied.

This was not a unilateral choice made by Yu Yi. Emotionally, Ye Si was still unable to completely let go of this city.

This is a kind city.

After she became a teacher, she came into contact with many demons, both children and adults, and witnessed too many kind faces. There was innate tenderness in everyone's eyes.

If there is a utopia in this world, it would probably be here.

That's why she agreed to Yu Yi's choice and returned to this place.

Moreover, she vaguely felt...

The truth of all this is hidden here.

“Aaaaaaaaaaaaaaaa—”

Suddenly, a shrill scream came from the end of the alley.

"What, what's going on?!"

Yu Yi was startled and turned her head to look in the direction of the sound.

It was the group of demons she had protected just now. They were in danger again. A tank driving on the road was aiming its main gun at them, and the black muzzle seemed to be able to swallow everything.

"give it to me."

Ye Shi gripped the sharp blade tightly in his hand, lowered his body, and prepared to go up and save them...

"Stop it!"

Suddenly, the 40-ton tank was overturned, its tracks spinning in mid-air, and its main body was instantly torn into three pieces.

The shells fired from the muzzle flew to the other side of the street, and the explosion caused an entire house to collapse, stirring up wind and waves, and the blinding fire cast a strange figure beside the tank.

It was a pair of giant winged claws made of dark magic, just like a giant bat, with sharp claws that could easily tear through steel.

The owner of the wing claw is a girl who looks exactly like Yu Yi...

"Ah, Xiaoling!"

Yu Yi jumped up excitedly and waved over there to attract the other party's attention.

"Sister Yuyi...and Teacher! Are you guys back yet?!"

After seeing the two, Ling was also a little shocked. He put away his wing claws and landed on the ground, approaching them.

After escorting the refugees to a safe area, the three of them went into the corner of the alley to talk.

"Xiao Ling, what on earth is going on here?"

Yu Yi asked nervously, wanting to know the time they left and why the demon world had become like this.

"I, I don't know either. It suddenly became like this this morning. A lot of iron ships fell from the sky, and a lot of robots ran out of them..."

Recalling the city that instantly turned into a sea of ​​fire, Zero clenched his fists and his voice trembled.

"The robot came out from...the ship..."

This fact was so shocking that Ye Shi was completely stunned.

She never expected that the facts would be completely opposite to what she had guessed.

I originally thought that those robots were tools used by the Demon King to investigate the "Falling Iron", but I didn't expect that the "Falling Iron" was the tool, responsible for transporting the mechanical soldiers to the Demon Realm.

When I think about it this way, many things that I couldn’t understand before can now be explained reasonably.

For example, why do these robots always carry out tasks in secret, why do these robots have the desire to attack the demons, why do they attack the demon king's daughter, and why even the demon king's personal guards are unaware of the existence of these robots.

"Falling Iron" is a weapon used by humans.

The previous "iron falling" incident was just a small-scale experiment, the purpose of which was to test the feasibility of the plan.

When we were investigating, we were only one step away from the truth, so why didn't we notice it?...

"etc."

Suddenly, Ye Shi thought of something.

Humans are able to teleport such a giant warship to the demon world, so does that mean... they have mastered how magic works?

"Sister Yuyi, Teacher, why did you come back to such a dangerous place..."

Zero looked at the two people in front of him, lowering his tail behind him, thinking that they would never meet again, and anxiety was revealed in his hazy red eyes.

"How could we abandon everyone and run away..."

Yu Yi held her hand, conveying her warmth and trying to calm her down.

"thump"

Looking at the scene in front of him, Ye Si's heart suddenly beat violently.

Burning streets, shrill screams, a city stained with blood...

At this moment, looking at Yu Yi and Ling in front of him, Ye Shi recalled the scene in his previous dream, which was exactly the same.

However, none of Yuyi's two companions died, and the demon king...

"Demon King"

That's right...

Where is the devil?

The devil often appears in dreams, but has never been seen in reality.

If those mechanical soldiers were not the Demon King's army, then from the very beginning, the Demon King had never really appeared and hadn't even done anything?

Now, the war between humans and demons has begun again. Where is the king of the demon world?

Perhaps, He will be the truth of all this.

"zero."

Ye Shi's expression turned serious and he called out Zero's name.
