"Okay, then give the old man what he left behind to my brother."

Su Xuan stretched out his hand, the meaning was very obvious, that is, he wanted something. But his smiling face immediately turned cold. I saw that the little girl shook her head and refused to take it out.

"Hey, little sister, be a man and keep your word. I've given you the drift technique, so you should give it to me. ”

"That's what you taught me, not what I brought it up myself. The old man said that only if I think of it, that's it. The old man also said, I want to keep my word, no matter what benefits you give me, I can't give you things, it must be what I want. The girl had big pitiful eyes and looked like she was about to cry.

Su Xuan only felt that it was dark in front of him, and he almost didn't fall to the ground, but he only felt that there were 100,000 crows flying on his head. The whole person is also like a frosted eggplant, and most of the day's work has been done in vain.

"You see Big Brother is very busy right now, and that thing is very important to Big Brother. Can you make a request? ”

The trick failed, and Su Xuan began to use emotional dramas. Not to mention, this trick is really smart. I saw that the girl took out a notebook from her arms and handed it to Su Xuan and said, "Since it is useful, it will be given to you."

Su Xuan didn't expect things to go so smoothly, he knew that this would be the case, and Su Xuan wouldn't have to be so troublesome. But before Su Xuan had time to be happy, the girl's next words once again knocked Su Xuan into the pit.

"It's been given to you, but you still owe me a request. I haven't figured it out yet, I'll tell you when I think about it. Saying that, the girl hugged the modified skateboard and left the store with a jump, without giving Su Xuan any chance at all.

"Don't be angry, don't be angry, it's just a little girl, maybe I'll forget about it after a while. What's more, I didn't have many opportunities here in the future, and it was impossible to meet the vast sea of people. Su Xuan kept comforting himself in his heart.

Now that it's okay, Su Xuan began to check the two things that the old man had left for him. First of all, take this notebook in his hand, this is the old man's experience, which records a lot of knowledge and principles about machinery. Like the old man's current status, this notebook will definitely be worth a lot of money if it is auctioned. But it was impossible for Ling Feng to do such a thing of killing chickens and taking eggs. With this notebook, his mechanic level will be at least one more level higher.

The first side was a word left for Ling Feng, saying that he was willing to let Su Xuan become his registered disciple, and how far his mechanic level could reach depended on his own creation.

In the previous chat, Su Xuan knew that the old man had apprentices, and there was more than one. He had five disciples. There are more other disciples, and it can be said that they are all over the world. So when the old man left, when he talked to him, the expressions of the people next to him did not change. Because the old man has a very common thing as a disciple, but there are few who have great achievements, and they have not let them lose their strength. All they care about is the old man.

Su Xuan not only did not feel unhappy because of his status as a registered disciple, but felt very excited. Thinking about how he apprenticed at the beginning, the old man didn't accept him. In the end, he curved the way to save the country and began to slap Ya'er, otherwise why Ya'er's impression of him was so good was all because of Su Xuan's hard work at the beginning.

Not to mention, with Ya'er's care, the old man finally agreed to Su Xuan to give him a hand. But he never took him as an apprentice. I didn't expect the old man to take him in when he left at last. This could be a windfall. So he was very happy.

Recognizing the preciousness of this notebook, Su Xuan carefully collected it. Then he picked up the black Rubik's Cube and looked at it carefully.

The appearance of the Rubik's Cube was unremarkable, but Su Xuan, who knew the old man's original reaction, didn't dare to think that it was just an ordinary thing. Otherwise, the old man wouldn't care so much. Moreover, this Rubik's Cube can actually block the detection of spiritual power, which alone has to be surprising.

"Report to the master, this Rubik's Cube doesn't look simple." At this time, Zhi Brain's voice sounded in his mind again, startling Su Xuan, and he didn't have a good temper to think: "If you don't say it, I also know that this thing is not simple."

"Did you find anything?"

"No, it's not easy to say without me."

Listening to Zhi Brain's words, Su Xuan was angry again. To say it is to say nothing.

"But I know one of the functions of this thing." I don't know if Zhi Brain did it on purpose, and the pause in one sentence made Su Xuan a little unbearable.

"So what do you say?" Su Xuan was more curious about this thing, so he endured the surprise that Zhi Brain brought him, and finally asked the doubts in his heart.

"I can only congratulate the owner on his good luck. One of the uses of this thing is that it can be used as a cosmic navigator. When we reach the universe, we will be free from the gravitational pull of the planet, and there will be no distinction between up and down, left and right, and at this time, it will be very difficult to distinguish the direction of the universe. Originally, I was going to do my own navigation, but with this thing, it's even better than myself. Except for a few dangerous mirrors, there is nothing to be afraid of. ”

Hear this. Su Xuan was surprised. I didn't expect that one of the functions of this Rubik's Cube is so powerful. As we all know, within the gravitational pull of the planet, the top of the head is up, and the foot is down. And then there's the left and right. But when you get out of the planet, there is no such distinction, it depends on how the spaceship flies. But it's not just flying, otherwise, it's harder to fly to your destination than to the sky. As a result, the three-dimensional orientation method of the universe was born. This orientation is also one of the far-reaching influences that affect human beings entering the universe. In geography class, it is all explained.

And this Rubik's Cube can be positioned, which is not a powerful function. In other words, even if you arrive in an unfamiliar star field in the future, you will not easily lose your way. This is simply tailor-made for the spaceship he is building, and it is no wonder that he is so happy.

"Not only that, but this Rubik's Cube can also be used for mecha operations, allowing mecha to make incredible movements and make mecha more powerful."

"Didn't you say there was only one effect? How did the two work. ”

"This is the same principle, which is the principle of spatial positioning. This Rubik's Cube has an infinite number of variations and can do countless spatial actions, and positioning is only one of them. Zhi Brain said in a tone that was not very good for your buddy, you are not learning in space.
