Early the next morning, in the room where Qi Xiao was temporarily staying. Pen "Fun" Pavilion www.biquge.info

"So, this thing can only be used once?" Qi Xiao said in the standard continental language as he played with the palm-sized purple diamond-shaped crystal in his hand.

"Well, each inheritance crystal is a one-time ......" Winnie's tone was full of envy, her eyes staring straight at the dim crystal, "It's the first time I've seen such a precious thing, I didn't expect you to have the opportunity to use it when you just came to this world......"

……

That's right, the reason why Qi Xiao was able to learn the lingua franca of the mainland immediately was all because of the crystal in his hand.

This thing, called the Inheritance Crystal, is said to be the work of a spell sage thousands of years ago.

It is able to store a certain aspect of knowledge, which can then be extracted into the mind of ordinary people.

It can be said that if there are enough inheritance crystals, you can even directly turn a prodigal child who has no knowledge and no skills into a knowledgeable scholar.

And the crystal in Qi Xiao's hand was sent by the investigator yesterday in the name of apology.

Although she knew that the other party might have another purpose, in order to communicate with her own demon as soon as possible, Winnie reluctantly accepted the crystal worth hundreds of gold coins.

……

"Are there any other inheritance crystals of knowledge?"

"Of course, but I can't afford the cheapest language inheritance crystals, so don't think about other kinds."

"It's a pity, I thought I could quickly grasp the knowledge here......"

"You think too much, if there really is, I would have used it myself." Winnie looked at her own demon who was trying to 'get something for nothing' helplessly, and as if she thought of something, she hurriedly said, "You are my demon now!" Even if someone gives you a Inheritance Crystal, you can't go with them! ”

"Demons? Yours?! ”

Because of the acceptance of the language inheritance, Qi Xiao knew the meaning of this word very well.

As a result, his indifferent expression instantly broke the work, and a helpless wry smile appeared on his face......

……

"Do you remember everything I just said?"

"Well, you've repeated it twice."

"No, I'm still not at ease, I'll tell you again!"

First! The girl raised a finger and stared at Qi Xiao seriously, "You can't stay too far away from me, otherwise you will be attacked by spells, so after the holiday is over, you must follow me to the academy!" ”

"Second!" She folded her hands and walked back and forth in front of Qi Xiao, "Our contract has been certified by the Moon God, and no one can break it, so you will be my demon for life, and you must not make an alliance with others again!" ”

"Third ......"

……

The girl repeated the rules that Qi Xiao needed to follow unilaterally, and only after seeing Qi Xiao nod her head for the third time in agreement did she say with satisfaction: "Although you have eaten a little more, but for the sake of your ability, I will reluctantly admit that you are my demons......"

Qi Xiao was already unable to answer, obviously just now he asked him not to make an alliance with others, but now he pretended to look disgusted, if I remember correctly, this is the tsundere mentioned in the book......

It is said that when a girl is arrogant, you must not open your mouth to refute it, otherwise you will fall into a curse called 'you can't find a girlfriend and can only be single for the rest of your life'......

"Alright, now come down to breakfast with me." After the girl finished speaking, she turned around and walked downstairs.

Looking at the other party's slender back, Qi Xiao unconsciously thought of his sister......

――There's no way to go back for the time being, so I'm going to live here as your 'demon' for the time being......

……

"Are you all losing weight?" Looking at the thin white bread in front of everyone, Qi Xiao asked with some smirk.

"It's not all you!" Winnie's cheeks flushed, and her eyes were full of shame, "If you hadn't eaten so much yesterday, Anne and I would have starved with you!" ”

"Okay, don't worry." Anne hurriedly stopped her sister's words and said, "I'll go buy food later." ”

"But ...... at home"

"Just listen to me for this kind of thing!"

Seeing Anne take out her majesty as an older sister, Winnie quickly silenced.

Then, Anne withdrew her untouched plate in front of Qi Xiao and smiled softly at him: "I've really been losing weight recently, can you help me eat it......"

……

After breakfast, Anne packed up her utensils and went shopping for food.

And since she couldn't leave Qi Xiao too far, Winnie went to her room to review her homework.

As for Qi Xiao, he was thinking about his future plans......

- Winnie's family doesn't seem to be wealthy, and their parents don't seem to be anymore...... Before going to find Bai Fei and Tang Yu, I still want to help them first...... In any case, it is necessary to let them have no worries about food and clothing......

――Speaking of which, after eating yesterday, my body seems to have become a little stronger...... Could it be that the ability has evolved again?

Qi Xiao, who was wandering in his thoughts, completely ignored it, it was precisely because of his gobbling up yesterday that he ruined the girls' life that was originally considered 'worry-free'......

……

- So, let's do something first.

Due to his lack of interest in business and his lack of understanding of the other world, Qi Xiao couldn't think of any ideas to make money for a while.

――Do you want to do research and sell patents again? But I don't know if there's such a thing as a patent......

Just as he was thinking, Qi Xiao's gaze inadvertently swept over the dim crystal placed beside the bed.

He was suddenly shocked, and then his deep eyes gradually brightened......

……

Sitting at a narrow wooden table in the room, Qi Xiao gently separated his spiritual power and poked into the crystal in front of him.

――Sure enough, it's a structure I've never seen before, and it's so complicated...... However, it should be possible to complete the deduction in three days......

By the time his mind turned, his eyes had closed, and his consciousness was completely immersed in his mind.

Then, countless flickering fluorescent threads emerge in the mind, forming a three-dimensional structure that is extremely complex and of unknown meaning throughout the space, and then these structures begin to collide, deform, and even entangle themselves with an indescribable mystical law......

……

Three days went by in a flash.

At this time, Qi Xiao was still sitting in front of the wooden table, but the table was filled with purple crystals that were indistinguishable, and unlike the already dim crystals, these purple crystals on the table were perfect inheritance crystals!

Seeing his masterpiece, he finally breathed a sigh of relief in his heart, and thought that it took me so long to research without theoretical support......

In fact, in the beginning, he only succeeded in synthesizing discarded hedrons.

However, as his research deepened, he accurately found the special substance that caused the crystal to shine in that linguistic hedron that linguistic inheritance.

After that, he began to consciously increase the proportion of this substance, and after thousands of experiments, he finally made a qualified spar......
