"This little guy seems to be ......"

Natsu recognizes the origin of the white-haired young girl, and it is the two bat envoys who have summoned the elder sister of the demon.

The little guy who was sleeping suddenly fell to the ground, and his head hit the cold and hard ground, and the pitiful encounter made her cry in pain immediately.

"Shut up!"

Wendy said coldly.

"Lord, master."

Sensing the aura of her master, the white-haired young girl suddenly stopped crying in fright, covered the place where her head was knocked on, and stood up from the ground tremblingly.

"What's the use of asking you two to eat and sleep all day?"

Wendy seemed to have always been dissatisfied with the two demons, and snorted and said:

"Stay there and don't move, don't cry for a while, no matter what you encounter, understand?"

"Nod"

The white-haired young girl didn't dare to make a sound, covered her head and nodded.

"Smack!"

Wendy summoned again, and a gray viper fell out of the Void Circle.

This viper has a peculiar appearance, with two protrusions on its head and an inverted triangular shape, which at first glance looks like a young dragon.

"Sizzle...... Sizzle......"

Suddenly summoned to a strange place, it was dissatisfied, spitting out a letter and scouting around to find out who its enemies were.

The snake's forked tongue collects information from the air, then concentrates the taste in two grooves in the palate, and then converts it into electrical signals that are transmitted to the brain to determine what objects are around them.

Soon it figured out what was going on inside the house, and there was a human who smelled delicious, but it was so powerful that it was quite intimidating; In addition, there is a mouth-watering bat breath that seems to be weak.

“！！”

For bats, snakes are predators, and the young bat girl sensed the danger at the first time, and covered her mouth to prevent herself from making a sound.

But the smell leaking from her body betrayed her, and the gray viper slowly swam on the ground, its head raised in the air, and began to approach her location.

"Leave her alone, there won't be any danger."

Wendy stopped Xia with a voice transmission, and said lightly:

"Although this demon is of little use, it is my subordinate after all, and I will not abuse her."

He also said that there was no abuse.

Xia was slandered in his heart:

People are sleeping well, but you have to summon them over, and you use such a rough way...... If only an ordinary human girl had fallen out of the way.

However, she also knew that Wendy would not lie about such a thing, so she pressed her mind to help.

But she still has a fighting bullet in her hand, which can be stimulated at any time.

Wendy glanced at her hand and didn't say anything.

“……”

As the venomous snake approached, the white-haired young girl's body began to tremble incessantly.

But the order given to her by her master was not to move, nor to make a sound, and she did not dare to disobey at all, and watched as the poisonous snake crawled at her feet, baring its fangs at her delicate calves.

“――！！”

The white-haired young girl closed her eyes tightly, and her hair became extremely hard at this moment, condensing into white thorns, standing straight behind her, which was a sign that she was terrified to the extreme.

Seeing that the viper was about to attack, biting on her snow-white skin, Wendy activated the summoning again.

This time, the movement was much greater, and I saw a black magic array appear in the air, different from the ordinary void magic array, this magic array was surrounded by pitch-black arcs.

A sharp bolt of lightning shot out from the center of the circle, striking the head of the snake with its mouth wide open!

Immediately, a thick black mist appeared from the void, and some kind of harsh sound wave was heard in Natsu's ears.

This kind of sound wave is not very lethal, but it will disturb people's spirits, and of course it will have no effect on her.

"Bang!"

The small viper was struck by lightning and slammed into the west wall of the room.

"Shh

The sonic black mist rushed towards it, and two sharp claws stretched out from within the mist, clutching at the viper's seven inches.

The poisonous snake did not show weakness, and began to roll up its body to entangle the enemy in the black mist, even if it was struck by the black lightning first, the strong body defense made it not suffer much damage at all, only paralyzed for a moment.

"Bats?"

Xia looked at the battle in front of him in amazement, although his body was one size smaller, he could still vaguely recognize the other party as Enkara - that is, the sister of the bat twins, the young girl with black hair.

"They have the ability to transform after drinking your blood, but because their strength is too weak, they look very young in both human form and ontology."

Wendy didn't seem to be worried at all that her demon would be left behind, and she didn't care about the fierce battle in front of her, but gossiped with Natsu.

"But these ...... Does it have anything to do with space magic? ”

Xia looked at it for a while and knew that the poisonous snake was definitely not the opponent of the bat, so he was relieved; Puzzled, he asked her:

"You just showed me the normal summoning technique......"

"Ordinary?"

The vampire girl said sarcastically:

"What are the three most important points to pay attention to when using summoning?"

"Correctly capture the soul fluctuations of the summoned object, accurate spell positioning, and ...... Maintain a stable energy channel. ”

Xia suddenly understood:

"You just ignored that last rule!"

Just now, before the bat in the black mist appeared, it cast a bolt of lightning from the Void Circle, saving the white-haired young girl before the poisonous snake bit her.

Perhaps because of the induction between the twins (bats and humans are both mammals), Nkara, as a younger sister, has long felt the danger of her sister, so she is ready to attack while accepting the call of her master, and the final blow is hit.

"Under normal circumstances, if there is unstable energy in the summoning circle, it will immediately cause the formation to collapse, making the summoning fail."

"If you're unlucky, you can even get the summon stuck inside, or the whole summoning process evolves into a terrifying explosion that can't be reversed!"

"How did Wendy do it?"

She was not stupid enough to ask, but silently recalled the change process of the space just now.

"Remember the ...... at the beginning"

She raised a hand and closed her eyes.

Then the hand slowly drew a line in the air as if it were enchanted.

"Don't be in a hurry, even if you comprehend the mystery, it will take years for the so-called geniuses of the human race to be able to use it initially."

The vampire girl sat back in her chair and cocked a white thigh:

"There are many applications of space magic, but the principle is the same, and if you can understand one of them thoroughly, then other methods may be derived."

Natsu didn't respond to her words.

Because she has now fallen into a wonderful state, the images of consciousness that she has never had are like deep patterns engraved in her mind, so that her hands unconsciously follow the movement of her mind.

"Where is she?"

At this time, Xue Qian's weak voice sounded from outside the door.

"It's right ahead."

Erin's voice followed, and the two of them had already walked to the vicinity of the room.

Wendy's pretty face lifted slightly, her eyes flashed red, and a transparent barrier appeared outside the door.

"The host is right in there...... Ay? ”

Erin slammed headlong into the door, only to find herself in a dusty hall with no trace of Natsu in sight.

"Strange."

Then she shrank back from the door, scratching her little head, and looked at the room with the door wide open, and Xia Heran was standing with her back to the doorway.

"Space...... is distorted. ”

Xue Qian was already attached to Edith's body at this time, and pressed her eyes and said:

"She seems to be trying some kind of hard time, so let's not bother her for now."

"The host ......"

Erin flew to the door worriedly, looking inside, not knowing what Natsu was doing.

But soon she felt that there was something unusual in the system, and hurriedly opened the information panel.

"Huh?"

Wendy also sensed the strange magic fluctuations and shifted her gaze to the silver-haired girl's hand.

Natsu's closed eyes opened slightly.

In that short period of time, it was as if she had had a long dream.

But she saw a lot of things in her dreams, but it was difficult to recall them for a while, only a clear image always occupied her mind, and it could not be removed no matter what.

"What is this?"

When she slowly opened her eyes, she found that a dark magical pattern appeared in front of her. (To be continued.) )
