"Mr. Zu?"

Seeing the old man quietly coming to the room, Ye Xianglun said in surprise.

"Although Brother Ye's method is ingenious, after two days of hard thinking and meditation, he has found a simpler way!" As he spoke, the old man took out the piece of Lugong gadget that Ye Xianglun gave to the old man that day from his sleeve, and after slightly rotating it in his hand for more than a dozen times, the six sides of the "Rubik's Cube" were completely assembled.

"Moreover, I also found that no matter how many steps it takes to disrupt this small machine, it can be completed in no more than 20 steps!" As he spoke, Mr. Zu snatched the small machine from the scholar's hand, and after a few slight rotations, he easily spelled out the six sides of the small machine.

"The number of God?"

After Ye Xianglun saw this phenomenon, he was taken aback, the so-called number of God is a difficult problem that scientists have studied for decades, and in the modern era of the earth, a scientific team from the United States, through the continuous calculation of dozens of computers, finally calculated the exact number of "God's number", that is, 20.

Although this result sounds simple, the process is extremely difficult, knowing that there are 43252003274489856000 different possible combinations after the Rubik's Cube is disrupted, and it is even more difficult to arrive at a minimum of 20 moves out of so many possibilities.

Perhaps everyone knows that some skilled Rubik's Cube players can even complete any interrupted Rubik's Cube in a few minutes, but they can use such a short period of time, completely with hand speed and brain speed to complete, they spend dozens of steps in between, more than hundreds of steps, and this also requires the support of a large number of Rubik's Cube formulas.

Every step of the Rubik's cube, at least 12 small noodles move with it, in this case, to complete the blending of 54 small noodles in 20 steps, the difficulty can be imagined, Ye Xianglun never expected that an old man from another world could solve the problem that has plagued scientists for decades in two days, and the surprise is self-evident.

"Ancestral ...... Mr. Zu, how did you do it!" Seeing the old man on the opposite side easily complete the "Rubik's Cube" spelling, Ye Xianglun couldn't help asking.

"This method can only be understood, not spoken, and when you reach that state, your intelligence will naturally figure it out. Seeing Ye Xianglun's surprised expression, the old man stroked his beard proudly, "Young man, thank you for lending the old man's small equipment, and the old man will return it to you as promised." ”

After speaking, Mr. Zu flicked his fingers, and the Lugong small machine was as if it was resting on the conveyor belt, slowly floating in front of Ye Xianglun's eyes, reaching out to grab the floating Lugong small machine, Ye Xianglun hurriedly raised his head to look at the old man, only to see the old man turn around leisurely and walk towards the door.

"By the way, by the way, the old man reminds you, in the past few days before the Music Note Conference, don't travel easily, even if you travel, you have to travel during the day, remember!" As soon as the words were finished, the old man named Mr. Zu "disappeared" into the room out of thin air under the gaze of the three of them.

"This ...... Is this guy a human or a ghost?" After a while, Ye Chen finally closed his wide open mouth and exclaimed.

"Squeak-"

While the three were still in shock, the door was opened.

"Mr. Ye, lunch is here, let's see if it suits your appetite?"

Pushing the door in, it was Tao Qian, who went downstairs to buy food, and while sorting out the lunch wrapped in lotus leaves, he placed the dishes and chopsticks.

"What are you looking at there, don't come over to eat!" Tao Qian followed the eyes of the three people to look outside the door, and found that there was no one outside, so he closed the door casually.

"Good...... Okay, everyone hasn't eaten yet, right? Come on, let's eat together!" After the door closed, the three of them recovered from the shock, and Ye Xianglun said to everyone with an embarrassed expression.

"Good...... Great!"

Turning their heads mechanically, Ye Chen and the scholar began to slowly return to their normal movements.

Since Tao Qian bought the amount of food for three people, plus the amount of a scholar, it was not too much, and the four of them gathered around the table and ate without saying anything to each other.

"Mr. Ye, I heard my husband say that there are only three days left before the note lands, I don't know what your plans will be in these three days?" After lunch, the scholar took out a cloth towel from his sleeve, wiped the oil stains on the corner of his mouth at will, slowly folded the cloth towel and put it back in his sleeve, glanced at the door casually, and asked with a farewell.

"Is there only three days left?" Ye Xianglun put down his chopsticks, looked at the door and window faintly, and his eyes seemed to see the world outside the window, "I will follow Mr. Zu's order, I will recuperate in the room these days!"

"This should be a good choice, I hope that after the note conference, Mr. Ye can still remember that there is a friend of Xiaotong in Shouchun City!" The scholar got up and put the Lugong small machine and the formula recorded from Ye Xianglun's mouth into his arms, leaving another piece of Lugong small machine and said, "This small piece of small equipment was originally intended to be given to Mr., and I hope Mr. Ye will not dislike it!"

"What did the little boy say, Ye Mou made friends regardless of age, he will see you again in the future, Ye Mou will treat each other as a close friend!" Ye Xianglun and the other three also got up and bowed their hands.

"The boy's surname is Cao Mingchong, and he is originally from Yancheng, the capital of Chu!" Seeing the three of them get up at the same time, the scholar said with a little embarrassment, "That's ...... The boy took his leave!"

When the three of them sent the scholar to the entrance of the stairs, they were stopped by the scholar and did not go downstairs.

After returning to the room, Ye Xianglun silently thought for a long time, Shouchun and his entourage, first by the note of Mi Taishou and eye-opening, and today by Mr. Zu's miraculous ability, so it seems that his journey as a pianist still has a long way to go, so when he thinks about it, he looks down on the two-star conference in front of him.

Sitting back on the futon in the hall, Ye Xianglun continued to close his eyes and breathe, because it was really boring to stay in the room, Ye Chen and Tao Qian took turns guarding in the room, but at night, the two of them never went out again.

The night passed by in a flash, and by dawn the next day, the three of them were awakened by the noise outside the street. After putting on his clothes, Ye Chen, who was still half-asleep and half-awake, pushed the door out first, and when he looked down at the scene on the street, he was stunned for a moment, and then shouted loudly:

"Mr. Ye, come and see, on the street below us, there is a corpse lying horizontally!"

Ye Chen's exclamation immediately attracted the two of them to go out quickly, and the three of them looked down at the street at the same time, and sure enough, they saw a corpse lying in the middle of the street, judging from the size of the corpse, it looked like a man, the corpse was covered with blood, lying on his back on the street in a "big" shape, and he was only holding a broken guqin in his hand, and the face of the deceased was hideous and terrifying, as if he had suffered great pain before his death.

At this moment, there was already a large number of people on the streets, inside and out, who were pointing at the corpses and discussing:

"This middle-aged man looks like a luthier!"

"On the eve of the note conference, there was a pianist on the street of Shouchun, which is too unusual!"

"Now it's up to us to see what the organizers Xiao Xiangzong and Shouchun Taishou will explain!"

"Yes, Xiaoxiangzong and Shouchun Taishou have the responsibility to maintain peace in Shouchun City, even the violinist has been killed, they must give a reasonable explanation!"

......

"Get out of the way!

Just as the onlookers were filled with righteous indignation and impassioned, a convoy of horses galloped from one end of the street, and the passengers on the horses were dressed in heavy armor, apparently from the government.

"Mi Tai is here, everyone get out of the way!"

As the officer dismounted and opened the way, the crowd quickly gave way to a bright road, and everyone turned back to yearn for it, only to see a general with a red tasseled helmet jumping off the horse, which was Lord Shouchun Taishou.
