The Lord's Mansion.

Song Cang looked at the two things placed in front of him, a wooden board with various squares, and a strange object that looked like a pineapple of wood, these two things Song Cang had definitely not seen, and he naturally didn't know the purpose.

"What is this?" looked up at Song Yi who was sitting in front of him, Song Cang frowned, this little grandson suddenly came to him with these two things at night, which surprised him.

"Grandfather, this is what I told you yesterday to give you. Song Yiwan smiled, very kind.

"It's... Give it to me?" Song Cang was stunned, he remembered that Song Yi did say yesterday that he would give him something afterwards, and he was very interested at first, but he didn't pay attention to it afterwards, because after seeing Song Yi's cleverness, Song Cang felt that this was a small trick used by the latter to get him to agree to launch a plan to save Song Tianyuan, after all, in Song Cang's insight, there are actually not many things that can interest him, and most of these things are extremely precious, and Song Yi definitely has no ability to get them.

However, now it seems that this little grandson of his own is not joking with himself, but what is this?

Curious and puzzled, Song Cang picked up something and fiddled with it, there was no spirit pattern on it, indicating that this was not a spirit tool, and no matter how you looked at it, it was just ordinary wood, and there was nothing precious, so Song Cang immediately made up all kinds of brains... Song Yi took this, isn't he implying that he is just a useless piece of old wood?

"This is called Kong Ming Lock, also known as Luban Lock, which is a very interesting folk game. Song Yi saw Song Cang's doubts, so he explained: "It seems to be a solid whole, but in fact, as long as you find the right path, you can easily disassemble it." ”

Hearing what Song Yi said, Song Cang was slightly stunned, he remembered that Song Yi had said something similar yesterday, any seemingly unsolvable problem, as long as you find the right way, you can easily solve it.

In order to verify what Song Yi said, Song Cang slightly urged his own vitality, which was released from his hand, drilled into Kong Ming's lock, and then fed back the internal information to him, which made him sure that the inside of this gadget did have some kind of exquisite structure.

"You say this can be solved?" Song Cang asked.

"Of course, it's easy. Song Yi stretched out his hand to take the Kong Ming lock, and then under Song Cang's eyes, he saw his two fingers clamped on a piece of wood at the top of the Kong Ming lock, and with a slight push, the wooden bar fell in, and with the completion of this first step, Song Yi began to pull out some of the wooden strips that were originally held one by one.

In just half a minute, more than 30 pieces of wood parts were completely disassembled by Song Yi in this way, and the whole process did not use the slightest violence.

"This... It's kind of interesting. Seeing that Song Yi easily removed the Kong Ming lock, Song Cang, who was still depressed just now, suddenly had a smile, but this smile was very faint, because he admitted that the gadget that Song Yi brought was very interesting, but it didn't seem to surprise him.

"It doesn't seem difficult, how can it be called a problem?" Song Cang said.

"Really?" Song Yi guessed that Song Cang would have this reaction, so he quickly reassembled the Kong Ming lock at a faster speed, and he still used his hands to block the assembly in the last few steps, and when it was finished, he handed the Kong Ming lock to Song Cang: "Untie it and take a look." ”

At this moment, Song Cang was not convinced: "What's so difficult about this?"

After speaking, he directly took the Kong Ming lock and began to try to disassemble it, facing the nine strata of the front and back, the left and the back, the upper and lower levels, Song Cang first tried to find the first wooden stick that could be pulled out, at this time he was full of confidence, and felt that what Song Yi could easily do, he should be more effortless.

However, a few minutes later, when Song Cang searched hard but couldn't find the first piece of wood that could be removed, he was suddenly a little embarrassed, and even almost wanted to smash the broken wood in his hand with violence.

Song Cang didn't believe in evil, he continued to look for a way, but time passed quickly, three minutes, five minutes, ten minutes... It wasn't until the twentieth minute that he finally became disheartened and wanted to give up.

"How is this possible to unravel?" Song Cang suspected that Song Yi had just used some trick that he hadn't seen, so he threw the Kong Ming lock back to Song Yi: "You can untie it again and show it to me." ”

"No problem. ”

Song Yi smiled slightly, took the Kong Ming lock, this time he directly slowed down his movements, and explained various principles to Song Cang, such as some places need to be pulled out at the same time on both sides, and some places cannot be pulled out directly, but must be slowly moved with other places, until a few minutes later, Song Yi completely unlocked the seventh-order pineapple Kong Ming lock in his hand, and the thirty-three parts were all placed in front of Song Cang.

At this time, Song Cang had changed from disapproval at the beginning to surprise, he didn't expect that there were so many tricks on such a small thing, and its raw materials were just some ordinary wood.

"It's me who underestimated this Kong Ming lock. Song Cang had to admit it, and now he finally understood what Song Yi said, this is indeed a difficult problem that needs to be solved in turn, which is amazing.

It's just that Song Cang is also very puzzled, just such a gadget, why has he never heard of it before?

"Did you come up with it yourself?" Song Cang immediately said the doubts in his heart, he looked at the more than thirty parts, and was very surprised: "The person who can design such an object is by no means idle." ”

"Uh... Previously seen in a book. Song Yi could only come up with his own set of all-purpose explanations again, in fact, Kong Mingsuo was not created by him, but an ancient folk puzzle game that he often played in his previous life.

"Then what is this?" After expressing his surprise to Kong Mingsuo, Song Cang set his eyes on the second thing, which was the Huarong Dao brought by Song Yi, since Kong Mingsuo was so magical, Song Cang felt that this second thing was by no means idle.

"This is Huarong Dao, play like this..."

Next, Song Yi introduced some information about Huarong Dao to Song Cang, such a puzzle toy that produced a kaleidoscope by moving each block, and finally moved the main block from the exit suddenly made Song Cang very interested.

Originally, Song Cang thought that Song Yi would give him some novel spiritual tools, after all, there were not many things that could interest him, but the two things in front of him directly changed Song Cang's concept, a Kong Ming lock, and a Huarong Dao, both of which were made of the most ordinary wood, the former had an exquisite structure, and the latter was ever-changing, which made people admire.

Song Cang, I like these two things very much, in fact, he hasn't been so happy for a long time.

After explaining the two things to Song Cang, Song Yi reassembled the Kong Ming lock.

"Oh, little one, tell me, do you want the old man to help you with something, or do you want anything? I can give it to you now. After accepting the two things presented by Song Yi, Song Cang also said to Song Yi with a smile.

Song Yi was stunned for a moment, and immediately understood that it seemed that Song Cang thought that he was sending something to please him, so he took the opportunity to make some request: "Grandfather... I'm just keeping my promise. ”

Song Yi has no purpose, he just wants to fulfill his previous promise, and he also feels a certain loneliness in Song Cang, although there are all kinds of people who respect him, but there are very few people who can really treat him as an old man.

Song Cang was also a little surprised by Song Yi's statement, but he didn't say anything, just looked at Song Yi, a relieved smile appeared on his face, through the contact in the past two days, he has become more and more fond of his little grandson.

"If I have time in the future, I will have to accompany my grandfather more often, and if there are any new things, you can show me. ”

"Of course, if you're happy. Song Yi smiled, and immediately looked at the already dark sky outside the house, at this time, he should also say goodbye to Song Cang and go back.

"Grandfather, then I'll take my leave first, and I'll come back when I have time. ”

A few minutes later, Song Yi left the head of the family's mansion, and at the door with only a faint light, he saw Qiao Yun, who had been waiting outside for half an hour, and the two smiled at each other.

"Let's go, go back. Raising his hand, Song Yi took Qiao Yun and walked in the direction of his house, and at this time, in a room in the mansion of the head of the family, Song Cang was interested in cracking the 'close' that Song Yi had arranged for him at the beginning.

On this night, there was only one old man, accompanied by a semi-circular moon that gradually rose, and the crisp sound of wooden blocks moving on Huarong Road.
