At noon, Song Yi returned to his house, a little hungry, so he asked Qiao Yun to find some food, but when a steaming table of food was placed in front of him, Song Yi suddenly felt a little bored.

Compared with the fish and meat stir-fry in the restaurant in the morning, this kind of coarse tea and light rice really made Song Yi more and more unappetizing, but considering the price of the former, Song Yi could only choose to settle, he ate slowly, while thinking that he owed Song Yan six gold coins, and was ready to find a time to pay it back.

And at this moment, a tall figure hurriedly walked in from outside the house, it was Song Qing.

Seeing Song Qing coming, Song Yi immediately put down the chopsticks in his hand and got up: "Dad, why are you here?"

"You're not hurt, are you?" his gaze fell on Song Yi, Song Qing swept it from top to bottom, he came over in such a hurry obviously because he heard about what happened in the bazaar before.

"I'm fine, it's just... Wounded a member of the Wang family. Song Yi also remembered after coming back that his move was a little impulsive, which might bring some similar and diplomatic troubles to the Song family, especially since the other party also had a young master-level identity.

However, Song Qing shook his head: "It's okay if you're okay, it's not a day or two since that kid Wang Cheng has been acting wantonly in the bazaar, this time it's just a matter of treating him, you don't have to take it to heart, no one will blame you, just pay attention to it in the future." ”

Oh, it's okay, I didn't want to take it to heart... Song Yi thought so, and replied, "I'll pay attention to it later." ”

"It will not be very quiet in Xinan Town these days, you have nothing to do and go out less, wait for the wind to pass, if you want to go out, go to your sister and let her take you out, so that it is safer." Song Qing said to Song Yi.

"Uh... I know. Song Yi nodded and said, he didn't want to go out when he heard Song Qing say this, did he have to go out and say to Song Yuqing, 'Sister, I'm going to go out, you protect me', it's too embarrassing...

After explaining to Song Yi, seeing that the former was eating, Song Qing didn't want to disturb, so he turned around and left.

Song Yi quickly ate a good meal, he cleaned up the table by himself, at this time a figure appeared outside the house, she walked in lightly, Song Yi turned his head and looked, it was Qiao Yun, at this time the latter was holding a few wooden boards that looked relatively new in his hand, as well as a knife, which Song Yi asked her to find.

"Young Master, this is what you want. Qiao Yun walked in front of Song Yi with a wooden board and a knife, the latter reached out and took these things, and then Qiao Yun took over the tableware on the table, and after she left with the cutlery plate, Song Yi began to ponder the wooden planks in front of her.

The reason why Song Yi asked Qiao Yun to find these things was because he remembered that he had promised Song Cang before that he would give him something, and now what Song Yi began to prepare was something that could please the old man, and the manufacturing principle of these things was not complicated, and Song Yi didn't even need drawings.

There were a total of six wooden planks in front of him, all of which were four times the size of the palm of his hand, rectangular in shape, and about two centimeters thick.

Suddenly, Song Yi seemed to remember something, and he felt something out of his sleeve, which was the knife-type spirit tool that he and Xu Pang had given when they bought Xuanling Wood before, it looked like a slender little dagger, and when he came back, he also brought back the knife that should have been handed over to Xu Pang, which was purely out of curiosity.

"With the urging of the Yuan Qi, you can directly sharpen ten times?" Song Yi remembered the description of the shopkeeper, he felt that this was a bit incredible, with his habit of looking at things with a scientific eye, he really couldn't figure out what the principle was, was it that after the Yuan Qi was urged, would the blade of the knife be sharpened? Or was it something else?

Song Yi picked up the small dagger and observed for a while, the runes engraved on it were very spiritual, so he first took the knife and slashed directly on the edge of the table, and an obvious scratch appeared, the sharpness was about the same as that of an ordinary knife, so Song Yi began to urge the vitality in his body according to what the shopkeeper said, and his thumb was on the spiritual pattern at the hilt.

Airplanes!

As Song Yi urged the vitality in his body, the small dagger in his hand seemed to have some kind of induction, and the spirit patterns began to be activated, at this time, Song Yi brought the blade close to his eyes, and he didn't see any change, he could only slash the knife to the edge of the table again.

Click.

The edge of the knife fell on the edge of the table, and the blade that could only make a small mark was now directly penetrated from the table to the bottom, Song Yi didn't grasp the strength, and the knife made a small opening on the wooden table with a thickness of about three centimeters in the way of cutting the belly.

This scene almost stunned Song Yi, he felt like he was cutting a cake just now, the originally hard table became very soft under the knife, now Song Yi can only believe that this knife can really become more than ten times sharper after injecting vitality, but what is the principle of this?

Song Yi touched the cut on the table with his hand, and he felt that the cut was a little warm, it seemed to be... Song Yi immediately understood the principle of this little dagger.

"Ultrasonic cutting...", a noun from the earth, came to Song Yi's mind, this technology of cutting objects with ultrasonic oscillators, is one of the technologies used to process high-hardness objects such as diamonds on the earth, looking at the small dagger in his hand, Song Yi guessed that he activated the spirit pattern on it after urging the vitality, and this spirit pattern has the effect of making the small dagger produce high-frequency vibrations that he can't hear or even observe, so as to have the ability to cut high-hardness objects.

So Song Yi picked up the knife he asked Qiao Yun to find again, and was about to try to scrape it with a small dagger again, he paused again, and only after thinking about it did he start to do it, and finally what he left on the small dagger were four simple fonts: Come here.

These four words, which were regarded as very unqualified in the previous life, have a special meaning in the eyes of Song Yi now, after all... He comes from outside this world.

"Let's get started. After figuring out the cutting principle of the small dagger, Song Yi directly focused on the wooden board on the table in front of him, with such a dagger that sharpened iron like clay, Song Yi's next things to make were much more convenient, he first used the ordinary knife to draw some structural paths on the wooden board, and then directly used the vibrating dagger to start cutting these wooden boards.

There are two things that Song Yi has to do, one is relatively simple, and the other is somewhat complicated, so he started with the simplest.

The first plank was cut in half by him, and half of it was cut into many squares of different sizes, including a No. 1 square with a side length of 1×1, and a No. 2 rectangle with a side length of 2×1, the largest of which was equivalent to four No. 1 squares, and the thickness of the plank was about two centimeters, and Song Yi did not need to be so thick, so those small squares were quickly cut to only one-third of the original thickness.

Then there is the other half of the plank, Song Yi first cut a groove in the center of which is about half the thickness, the length of the groove can accommodate five No. 1 squares, the width is four-fifths of the length, and directly below the groove, Song Yi opened a small opening that can accommodate those small squares in and out.

It only took Song Yi ten minutes to make the outline of this first thing, and then the details were perfected, adding up to a total of about half an hour, which is the speed that can only be possessed under such a convenient tool as shaking the small dagger, and when he completely created this puzzle game from the ancient folk of the Chinese country, Qiao Yun also just finished her own thing, she is now the exclusive maid of Young Master Song Yi, so in addition to being in charge of Young Master Song Yi's affairs, she suddenly became very idle, so she came to ask Young Master Song Yi if there was anything else to arrange。

And when Qiao Yun walked into Young Master Song Yi's house lightly, she happened to see this thing placed on the table, at this time Song Yi was filling those small squares into the grooves of the wooden board, and when he saw Qiao Yun coming, he suddenly had a thought.

"Xiao Yun, you come over and unravel this, there is a reward for completing it. ”
