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

"There should be someone free at Darwin, right?"

"Ah, yes. Because my project has come to an end."

"I'd like to lend you some help Kelly, is that okay?"

Dalwin looked at Nia with wide eyes, showing concern that he had never seen before: "Of course. I will make arrangements to ensure that we can catch up with the progress."

Nia smiled and nodded. It was a small thing, but it surprised and expected everyone. Of course, because the other person is a child, they do have opinions.

But Nia was able to convince the other person every time and never changed her opinion or considered other people's feelings in front of adults. But now, Nia accepted Kaiping's words easily.

These small changes make everyone feel a little uneasy and have great expectations.

When it became noisy outside the window, Kaiping was alone in the office organizing information. He separated the papers into bundles and tossed the bundles he no longer needed into the trash. Instead, he stared at the trash can where the papers had been thrown away.

"Well, what a pity." As Kaiping muttered, there was a knock on the office door.

"Eh? Kaiping, are you still here?" Ersa walked in.

"Yes. I just finished. Miss Elsa, do you work overtime?"

"The new guy I talked to this morning made a mistake. If I help her, I won't be able to finish my own job."

"That's really it..." Kaiping frowned.

Elsa smiled at this, "Don't worry, it's all my fault," she said.

"Compared to this, Mr. Kaiping and the director are both young people, and they work overtime."

Kaiping turned his head: "The director should have gone back, right?"

"Eh? When I went to deliver the express, I found that the director was still in the office."

Kaiping felt helpless: "Really, I told him to go back early last night." After Kaiping finished speaking, his eyes fell on the document.

"Anyway, I'm going to send these reports up and blame him." Kaiping happily picked up the documents, and Elsa laughed: "Only you dare to blame the director."

Kaiping replied: "There is no such thing." and then left.

Afterwards, Kaiping quickly went upstairs to the director's office. The brisk footsteps grew louder. When the sound reached its highest point, Kaiping forcefully opened the door to the director's room.

"Director! Are you still there?" He walked in, but no one was there.

"Oops?" Kaiping tilted his head.

The desk that had just been tidied up was already covered with papers, and in the center was a small package. The chair opposite moved slightly.

Kaiping narrowed his eyes and looked at me: "Director, as a genius, it is really ridiculous for you to hide in such an unreasonable way."

From the other side of the pile of documents, Nia emerged with shining eyes: "Don't call me a genius. I don't like to use that word to describe it."

Kaiping deliberately ignored that sentence: "I told you to go back."

"Um."

"Not 'eh'."

"But it's almost done."

"Really...can you take a look at it?" Kaiping said to Nia. Nia smiled and showed Kaiping a large piece of paper in his hand: "This-"

Keping took the paper.

Nia, unaware of this phenomenon, looked up at Kepin.

"I'll return it to you tomorrow." Kaiping finally understood after finishing speaking.

"How despicable!" Nia tried to take the thing back, but Kepin held it high and out of reach, only to jump multiple times. Nia finally gave up and lowered her head.

At this time, the small package from before appeared in Kaiping's sight, and he asked: "What is that?" Nia also noticed it, and picked up the small package and said, "Oh, this was just delivered, it's from Egypt." Sent by Jesus."

"Just now? Did we originally have such a plan? And this time is a bit late for express delivery..." Kaiping felt that the time was strange.

"Elsa said the same thing."

"What's inside?"

"Would you like to open it and take a look?" Nia peeled off the tape on the small package.

Seeing this scene, Kaiping felt a little uneasy: "Sir, who is the sender?"

"By the way, I forgot to look at the sender."

At this moment, Kaiping suddenly remembered the document in his hand, snatched it from Nia, then reached down and said, "Wait a minute!" In an instant, the small package emitted a dazzling light.

There was no sound or impact, just light illuminating everything around it. Kaiping couldn't help but close his eyes.

When the light faded, he was finally able to open his eyes. Then he opened the small package and tilted his head slightly.

Nothing has changed. The room was still the same, with only Nia holding a small package and a small piece of paper in front of her eyes.

"What just happened...?" Nia looked at the question mark in Kaiping's mind, frowned and looked at the piece of paper intently: "I know the sender, it's Sam." Nia handed the paper over To Keping.

"Challenge." It was written in elegant font.

"Nia Fulzbelt, if you are called a genius, then solve this problem. Sam." That was all on the paper, but the handwriting was clearly Sam's.

How funny, Keping thought after reading it.

When Keping's eyes returned to Nia, he was taking out a palm-sized white box from the small package. In an instant, the white box shimmered and displayed red words and spells in the air. Nia placed the white box on the table.

"It's so boring," said Keping.

"Same feeling," Nia replied, and they both stared at the door.

Keping went to the doorknob and tried to touch it, but went right through it.

"The spell of spatial isolation is woven into it." Nia said, and Kaiping said: "Is that really the case?"

"A trap magic that enforces isolation. To lift it, it seems necessary to solve it."

Kaiping followed the text in the air with his eyes: "'Saira's optical academic theory'?" Nia smiled happily at Kaiping's words.

"As expected of Kaiping, he immediately realized the application of this minor theory." As he spoke, Nia stretched out his index finger to a string of letters in the air.

Then, his fingertips touched the space, and a blue line appeared: "It seems that the answer is to be written here." Nia started writing as he spoke.

When Kaiping saw this, he was surprised that Nia had solved the mystery and could not hide his surprise.

“Saira’s Optical Formula Theory“

A long time ago, the imperial magician Adman Sela proposed a theory about light-based magic. In light magic, there are differences in the magic value in the effect range and events. Are there differences between individuals? Or is it possible to ignore these differences and construct spells in the field of magic?

This is an academic theory that only scholars who have conducted in-depth research on light attribute magic know. Keping felt uneasy when he saw these questions. What was the strange thing on his mind? Nia's hand stopped as he watched.
