Use the power of the Demon King to destroy those reincarnated in another world

Nia untied the restraints and picked up Raila angrily. Kaiping also glanced over there: "She was poisoned, right?" Kaiping immediately understood the situation through Raila's wounds.

"Infused with magic factor."

"It's really troublesome."

"It doesn't matter, she can't move for the time being, but she will be fine." Nia said, putting Raila aside again, and stood up apologetically.

"As for you, Kaiping, you have to use your body to pay for your lateness."

"I see."

Nia stared at Keping and Allen who were making boxing postures. However, Allen opened his eyes wide and showed a shocked expression: "Wait!" His eyes fell on the stone brought by Kaiping.

"Summoning!? Summoning humans!? What a joke!" Alan's face showed irresistible surprise.

Usually, summoning refers to summoning and driving monsters or spirits through spells or props.

Of course, there are exceptions, and there are cases where people are summoned from another world, but that requires senior magicians to prepare for several months, which is very troublesome.

Moreover, the probability of success is very low, and it is not uncommon to lose magic power and die during the summoning process.

In this world, summoners are very rare for these reasons, and regular summons also require signing a contract with a monster or elf. As long as the contract is signed, summoning is not that difficult, but the problem lies in the process.

The summoner makes a summons through a door called the "Summoning Gate" that connects the other world and the present world. The monster or spirit that signed the contract will respond to the summons through that door.

In other words, in order for a person in this world to pass through that door, he must first be thrown out of the original world and then be summoned back through the door again.

Although there are records in the literature about people who researched the summons and went there through the door, but no one has ever returned to the original world as a survivor.

Allen looked alternately at Kepin and Nia. This man named Kaiping even put his own life on the line in the Nia experiment, which had no precedent to guarantee success.

Suddenly, a smile filled Allen's heart, and it turned from a hahaha laugh to a loud laugh.

"You are all crazy! Completely crazy!" Allen stood up and pointed at the two people with his right hand.

"Withdraw what I said before, 'you' are not weak beings." He opened his arms and smiled.

"What will you do next?" Alan asked happily, and then his arms turned black, and Nia suddenly felt a chill.

"Keping."

"OK."

"Let's do 'that'."

Kaiping looked back slightly at Nia behind him and nodded.

"Mutual understanding." When Nia whispered this sentence, Kaiping and Nia shared their thoughts for a moment.

"Okay, let's start the experiment." After Nia finished speaking, Kaiping lowered his head slightly. In an instant, Kai Ping's leaping body jumped in front of Allen.

Allen only reacted at the last moment, dodging Keping's straight kick.

"I see, using Keping's strong muscles to replace the weaker Nia in close combat." Then, Allen avoided Keping's large left punch in the air.

"Mutual understanding" is to judge the strengthening parts and attack methods through shared thinking, eliminating the waste of time in verbal communication.

Eren retaliated by flashing a Dark Spike from directly below Kepin, who jumped backwards to avoid the attack.

"It's efficient, but it feels a little weird."

Keping certainly has a strong body as a researcher. But in fighting, he is an amateur, and in fact, the movements of a person who is used to fighting may be more troublesome.

"If you just deal with him, you can easily win at this level..." Allen judged through certain elements, and was also troubled by a strange feeling.

That's his instinct. Allen's instinct told him that this was not a battle that would drag on for a long time.

The opposite of this is curiosity. After seeing the previous summons, Allen was full of expectations for what kind of performance Kaiping would perform, and this excitement disturbed him.

"There is no way, I can only act according to my intuition now." He made this judgment based on the rare situation in his past experience.

"Death Star!!"

Seven rays of darkness flew from Allen's body, forming a frame shape. They passed by Kaiping and flew towards Nia.

"Just use one of them to hit the left shoulder?" Just as Allen was thinking about just making the other party suffer some injuries, Nia's lips raised a smile.

"Synchronized!!" Before Nia could finish her words, the spear hit "it" and then shattered.

Its entire body turned black and turned into a knight-like "it" made of darkness. It shattered those spears in front of Nia.

Allen felt a sense of surprise and looked at it. At this time, Kaiping's figure had disappeared.

"Sure enough, it still takes some time to prepare."

Through the Dark Knight's voice, Allen confirmed that the man was Kepin.

"Yes, there is still room for improvement." Nia glared at Allen, "Come on, 'Dark Knight'."

When Kaiping heard this, he turned his head slightly: "Is it true that I can only use this name?"

Nia looked at Kaiping angrily.

"Uh, no, that's not what I meant..." Kaiping quickly denied.

"It seems you have some misunderstandings about the tacit understanding." Allen shook his head helplessly.

Kaiping looked at Allen and took a posture: "I'm really sorry. But if you underestimate me, you will suffer a big loss."

Regarding Kaiping's words, Allen chuckled: "I won't take it lightly, come on!" As soon as he finished speaking, Allen was knocked to the ground by a blow, and his vision was shaken.

"What the hell happened!?" Wherever Alan looked, Keping was swinging his right foot.

"Did he kick him down?" Allen was only confused by this completely invisible fact.

A sharp angle appeared on the left side of Allen's head. Allen twisted his body, strengthened his arm, and used this arm to jump and keep distance.

When he adjusted his posture in the air and prepared to land, the sharp angle was approaching. He cursed while forming a black wall to block the excitement.

However, Gekkaku's left fist easily broke through the wall and hit Allen hard.

Although the fist was not powerful, it was enough to knock Eren down, and Eren came to a halt in the air while tumbling and jumping high from the roof.
