……

"It's finally over."

In the not-so-bright room, Xu Mu frantically put down the pen and paper.

"Why is there such a thing as mathematics and physics in this world?"

I don't know who I'm asking, Xu Mu leaned back on the chair and looked up at the ceiling, a little loveless.

For most of the day, he racked his brains and used a full fifteen large sheets of rice paper, which could fill the entire room when they were spread out, and this was only less than half of the tasks assigned by Charles.

"At 749, the decimal point should be two places after it, you wrote it wrong."

"So the data behind it is also wrong."

Charles floated out of Xu Mu's body and read all the calculated numbers in a very short time.

Xu Mu held his forehead, opened the stack of rice paper, and found the error in the upper right corner of the third page.

"Distracted."

He scratched his head, he had been sitting here all day, he hadn't eaten lunch, his nerves were paralyzed, and he wasn't a robot, so it was strange if he didn't make a mistake.

"The construction of nuclear weapons, every joint cannot be ignored, I asked you to use the ion exchange method to extract uranium, but you miscalculated its adsorption content after solid-liquid separation."

"This is only a small part of it, if you are wrong in this data, the final result will inevitably be skewed by 108,000 kilometers."

"Be careful, if you don't kill Velitaan by then, you will blow yourself up first!"

Charles snorted coldly and criticized unceremoniously.

In fact, Xu Mu was already smart enough, but it was easy to go from thrift to luxury, and from luxury to frugality, and it only took thirty minutes for the man to learn the extraction and purification of uranium at night.

The speed and precision with which he thinks about problems are comparable to his high-tech chips, and he only needs to speak and then calculate, and he doesn't need to worry about anything.

"Let me be a salted fish quietly, or liberal arts are suitable for me."

Xu Mu leaned back on the wooden chair, opened his mouth and sighed exhaustedly, compared to the humans in this world, he felt that the humans living on the Blue Star were the real powers.

They can go from a barbarian who doesn't know anything, step by step, to create such a complex weapon, and even destroy the world, and the atomic bomb he wants to learn is still relatively backward!

"This is just data, when you figure it out, I'll take you to make the tools you need, and then go to the mine to purify uranium."

"Stop, stop!"

There are even additional production tools, which are extremely difficult high-tech, Xu Mu heard this, and his head was two big.

He kind of understood why the guy in the Heavenly Palace was unwilling to learn, this was not only a waste of time, it was a waste of life!

"My Nangong family also has a fixed school, but unfortunately not many young people are willing to go."

"Even if they are forced to go, they will only sleep in class."

In the side room, a woman in a white dress walked out, holding a snow-white kitten on her chest, and she got it out of nowhere.

"Look at how old-fashioned you are when you are about the same age as me."

Seeing her out of the house, Xu Mu immediately sat up straight, a little restrained.

It was the first time that a woman had lived in his home.

"What are you studying?" , The woman ignored Xu Mu's words and asked with some curiosity.

She knew that Xu Mu had been sitting here for a whole day, so she was inevitably a little curious.

"Blind learning, blind learning."

Xu Mu crumpled the stacked rice paper on the side and threw it next to the kang cave, and then asked casually:

"Nangong senior hasn't come back yet, his injuries actually need to be recuperated."

Xu Mu felt that he had nothing to say, so he asked boredly.

"He should be back soon." , The woman in the white dress still didn't mind Xu Mu's movements, "Probably...... Five seconds later. ”

Xu Mu heard the number, and then he was at the door, and heard a sound of footsteps.

"I also know that I should recuperate, but I just can't be idle."

Nangong Maoguan's voice came from afar, and then his body appeared at the door.

"The old man watched the sky and always felt that it was going to rain in the next few days, so he took the time to walk around."

"But when I came back, I met someone, guess who?"

Xu Mu shook his head:

"I'm not curious about such things."

"But even if I don't ask, my seniors will tell."

"Or do you know me."

The old man smiled, and then took out from his bosom a scroll of booklets with golden skins and sewn with satin.

"I met that, it was a supernatural from the Demon Slayer Division, and he asked me to teach this thing to the village chief of your village."

"Out of curiosity, I opened it and took a look, but I didn't expect the things on it, tsk......"

Xu Mu was a little curious in his heart, it turned out to be the person from the Demon Exterminator, what did they have to do with the village chief?

"Xu Mu, male, nineteen years old, except for the supernumerary of the Demon Division, a night watchman in Fengqing Village, was accidentally caught in the fog and died in the tiger's mouth last night when he was in a hurry to support Xishan."

"Because of his meritorious service in saving people and loyalty to his boss, he made an exception to promote Xu Mu to be a regular person to eliminate demons, and rewarded one hundred taels of silver, a total of five hundred catties of carnivorous animal skins, and asked Li Toyota, the head of Fengqing Village, to come to the stage to receive it at the summary meeting of the Xishan incident ten days later, above."

Nangong Maoguan didn't sell Guan Zi anymore, slowly finished reading the text on it, and then handed the booklet to Xu Mu.

After Xu Mu glanced at it roughly, he scratched his head with a strange expression:

"It's my ......

"Death notice?"

"Yes, they must think you're dead." , said the old man.

"Okay."

Xu Mu couldn't laugh or cry a little, holding his death notice, this feeling was really amazing.

"They saw me being beaten into the fog and thought I should die, but it's normal."

"But it's obvious that someone pushed me, and many people have seen it, but when I got to this, I only brought it by accident, it seems that the person's background seems to be very strong?"

Xu Mu turned his head to look in the direction of Xishan, and his eyes suddenly became sharp.

How can I be regarded as helping to destroy two pollution sources, but in the end I was framed by my own family, who can tolerate this?

The guy in the Heavenly Palace, of course, couldn't bear it.

"It doesn't matter what his identity is, when I complete the Lei Fa cultivation, I will kill him!"

Hearing the faint sound of thunder in the shadows, Xu Mu and Charles looked at each other, and then shivered at the same time.

- What a deep resentment.

"You're right, that guy did disturb him in a relationship."

"But even if you don't go to him, I'm going to go, at least to get an explanation."

Xu Mu took a deep breath, then put the scroll in his pocket and transmitted it to the Heavenly Palace through the shadow.

The two of them share a body, and whoever wants this body to die is his enemy.

If he has a good attitude of admitting his mistakes, then he can let him go as he pleases.

If the attitude doesn't work......

Then it's a shot.

Xu Mu exhaled lightly, and then thought silently.
