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

Eren was swallowed up by darkness and disappeared. After bidding him farewell, Nia quietly walked towards Keping: "To be honest, it's hard for us to say we won."

"Yes. In this place, it doesn't make much sense." After Kaiping finished speaking, Nia silently moistened her eyes: "I'm sorry, Kaiping. In order to stop Alan, I need your power."

"I understand. It's been great to fight with you and protect you."

"This divine realm——"

"Please never use it again." Keping stopped, and Nia's lips trembled. He was silent, tears streaming down his cheeks.

"Really, this is a 'final' farewell, sir."

"I don't want to, Kaiping. Trap you here, and I'll just live leisurely outside?"

Kaiping smiled in surprise at Nia's words: "Really, you obviously asked for it yourself, you are still a child."

Kaiping took off his armor and knelt in front of Nia: "I am really happy to be able to look at you at such a close distance."

"but……"

"No, it's not a 'but'. There's no need to be afraid. After all, you still have—" Kaipin's eyes turned to Raila, "—family is here, right?"

As she spoke, tears fell from Raila's cheeks. Kaiping was surprised by this sudden scene. Raila put down her bow and knelt beside Nya.

"We are all family. We are all family..." After saying that, she gently buried her face in Keping's shoulder. Kaiping frowned and stroked Raila's head.

"Miss Raila. From now on, you must protect sir. Please be strong."

"...just for now."

Keping looked confused, but he buried his face in Near's chest. Although Kaiping felt helpless, he hugged them tenderly: "I will always be by your side. Always, always by your side."

Kaiping let go of them, touched their heads gently, and then smiled softly: "So, please don't cry. Please don't be sad."

Kaiping stood up and left them slowly: "So, please don't forget. Being able to meet you and become a family is the best life for an immature person like me, and I can be proud of it."

"Keping!"

The world shook as Nya tried to take a step. Despite this, Kaiping still smiled: "Okay, it's time to say goodbye. Finally, I ask you two to go all out to survive. This is the task I give you."

When there is a crack in that smile, the world shatters. Then, it became the space where Nia and the others were originally.

Eren fell to the ground in front of Nia and Raila, who were holding out their hands. Allen covered his head and stood up: "What happened? Am I still alive?"

Nia put down her arms and looked at Allen quietly: "Yes. My divine realm is the spiritual world, and physical phenomena will not be reflected in reality." Nia continued, and Allen couldn't help coughing, his mouth Bloody vomit spurted out.

"The mental anguish comes with it. You are now unable to use magic normally."

Allen looked at Nia painfully: "Did I lose?" As he spoke, a happy expression appeared on his face.

"Why don't you kill me?"

"Same reason as you, uncle."

Allen raised his head in surprise, and then laughed: "Stop mentioning the family, it will only mess up."

"I am willing to sacrifice everything for science. This is what a scientist is."

"It's so similar."

"Is it my dad?"

Allen shook his head and said in denial: "It's your grandfather. You guys are really a bunch of lunatics."

Nia was speechless. Allen laughed, coughed again, and spit out the object in his mouth. Then he said, "But this is not okay. I can't accept it."

"What?" In front of the confused Nia and Raila, Allen showed an evil smile: "Scientists must be lonely. Moreover, I have not completed the agreement between us."

"What are you talking about?" Nia asked. Allen still kept the smile and stuck out his tongue, where a magic circle was drawn.

After Nia saw it, her eyes widened: "Magic?"

"Although magic cannot be used, magic is another matter. Then I will show it to you as agreed. Let you witness something you have never seen before-"

The magic circle glowed red. Raila hurriedly hugged Nia and left Allen. But the explosion only damaged Allen's head, which was smaller.

Nia looked at Allen who fell on the ground sadly: "Uncle."

Raila breathed a sigh of relief, but the ground began to shake violently, and Raila and Nia looked around.

"It's dangerous here. Shall we leave?" Raila asked, and Nia looked at Allen's body without his head.

Was he planning to do this from the beginning?

He should have no reason to give up his life. Although she was confused about such incomprehensible behavior, Nia nodded and supported Raila's decision: "Now we just want to know what happened. We have to get out quickly."

After hearing this, Raila replied: "Okay." She hugged Nia and started running out.

Leonardo looked at the scene in front of him in surprise. The dark giant monster has been repeatedly fought and blocked with the "Knights", and its power clearly transcends dimensions, which makes people feel frustrated by the high-strength defense power of its appearance.

Despite this, Sirius, the members of the "Knights" and the adventurers of the Adventurer's Guild managed to keep the city safe and did not allow them to enter the city.

However, the city suddenly shook. Astonishingly, darkness poured out of every corner of the city.

"Is the amount of darkness infinite?" Leonardo muttered displeasedly, and Sirius said beside him: "It is possible."

"Will an opponent make imagination a reality? We'd better not think with common sense." Sirius continued, and Leonardo agreed, but his face turned gloomy.

"But then there will be concerns underground, can the Empire and Dutch handle it well?"

"There's no point in thinking about it. We're already busy enough with our own tasks, and it's already difficult to stop that giant."

"Well, indeed."

The knights and adventurers surrounded the giant and wreaked havoc in the distance between them. It can be seen in its behavior that it runs around ignoring the city's creators, making them aware of the childishness of their thinking.

Just as the two were considering the next step, a voice came from behind: "Captain!" The two turned around, and a seriously injured and staggering knight flew over.

"Ralph, what happened?" Sirius hurriedly supported Ralph and helped him float in the air.
