After school, because according to the agreement, Tan Xiaotian needs to clean the classroom after class in lieu of tuition, so he went home relatively late, although Tian Qingyou did not have this kind of problem, but he used to go home from school to play with Tan Xiaotian, Tan Xiaotian was not there, and it was not interesting to go home early, so he also stayed to help clean, as for Yuan Lang, there are two children who are busy with work, so he doesn't need to work hard, and the two children are tossing in front, and he goes to the back to rest - to be honest, what is there to clean in the classroom, the reason why this task is arranged, It's just to persuade Qiu Ju to agree to Tan Xiaotian's request to study at 'Endless Learning'.

Although the task of cleaning the classroom is not easy for the two children, it is not too hard, Tan Xiaotian and Tian Qingyou first moved the tables and chairs to the side, swept them with a broom, and then rearranged the tables and chairs, and then wiped the tables and chairs with a rag, and the work was completed.

"I'm so tired." Sitting down on the chair, Tian Qingyou said exaggeratedly while using his hand as a fan to fan himself, although his body strength is not lost, but Tian Qingyou's strength is not exercised, but eaten, so his strength is very great, but his endurance is not very good, because the work that requires strength such as moving the table is mainly done by him, so at this time his forehead is already sweating.

"Then you sit down first, and I'll go and tell the teacher." In contrast, Tan Xiaotian's situation is much better, on the one hand, his job is to sweep the floor and wipe the table, and the amount of labor is much less, on the other hand, he is active by nature, can run and jump, and his physical fitness is actually stronger than most children of the same age, at least not so tired that he doesn't want to move.

"Okay, then you can go." ――After cleaning the classroom, you need to report to the teacher before you can leave, and since you are too tired to move, let me do it every day.

Putting the rag back in the corner basin, Tan Xiaotian left the classroom and walked to the back - it was the first time he had come to the backyard of Endless Learning, and he didn't know where Yuan Lang was, so he could only look for it slowly room by room.

"Click, click", there was a staccato sound in his ears, it sounded like something had fallen on a hard object from a height, the child was curious, and following the direction from which the sound came, Tan Xiaotian slowed down and looked for it.

The place where the voice came from was a room much larger than the utility room where he and his aunt lived, the door of the room was half-covered, looking through the crack in the door, the first thing I saw was a bookshelf against the wall, the bookshelf was very large, it was estimated that it was difficult to touch the top with the size of Tan Xiaotian, the bookshelves were divided into five layers, and each layer was neatly stacked with books

With so many books, could it be the legendary study? Tan Xiaotian guessed in his heart.

In front of the bookshelf is a desk, the desk is very wide, a few points wider than the large board used for cooking in the back kitchen of the Yuelai Inn, there is a stack of books, a pen holder and a blue-gray inkstone, in addition to this, there is also a wooden board, the wooden board is square, one inch thick, about two feet long and wide, the surface is pale yellow, the upward side is drawn vertically and horizontally with many straight lines, so that the surface forms many small squares, some black, white small things like buttons are placed on those small grids, some places are sparse, some places are messy, As for Mr. Yuan, he was holding a very old book with a frayed cover in one hand and reading it, and with the other hand, he took out some round things from two small jars made of wood and put them on the wooden board from time to time

What is the teacher doing? Are you reading a book or playing? - Seeing Yuan Lang's focused appearance, Tan Xiaotian was very curious.

Moving his gaze from the book to the wooden board, Yuan Lang frowned slightly, as if he was thinking about something, after thinking for a while, he suddenly shook his head, reached out and pushed the things on the wooden board aside, rearranged them again, and occasionally looked up, and found Tan Xiaotian standing at the door, seeing that the other party's eyes were staring at the movements of his hands, after being slightly stunned, a smile appeared on his face, "Heh, every day, have you finished cleaning the classroom?" He asked.

"Well, teacher, what's that?" Tan Xiaotian replied, but his eyes were still fixed on the wooden board that he had never seen before.

"Heh, this is Go, I haven't seen it before, right?" Yuan Lang beckoned for Tan Xiaotian to come closer, and he said with a smile.

"Go? What is Go? Tan Xiaotian asked curiously-for him, this is a noun, just like the "Three Character Classic", "Hundred Family Names" and "Thousand Character Text" that he memorized before, although he can memorize it well, he doesn't know what those words or words mean.

"Go, heh, to put it simply, is a kind of intellectual game." Knowing that the other party was too young and could not understand what he said too deeply, Yuan Lang tried his best to explain in a language that children could understand.

"Game?!" Tan Xiaotian's eyes instantly brightened several times brighter than just now - there was no child of his age who didn't like to play, and the more novel the game, the more interested he was.

"Yes, it's a game." Yuan Lang nodded in confirmation.

"How do you play?" Tan Xiaotian immediately asked.

"Want to learn? Hehe, at your age, it might be a bit difficult to learn this. Yuan Lang smiled.

"Huh? Why? Listening to the teacher's meaning, it seemed that he didn't plan to teach himself how to play, Tan Xiaotian was disappointed and very puzzled - didn't he just put something like a black or white button on the wooden board? Such a simple thing can be done by yourself, how can it not be?

"Hehe, don't think it's very simple just by putting the chess pieces on the chessboard, but in fact, there is a lot of knowledge in it. You're too young to understand the truth, so if you really want to learn, I'll teach you when you're older. Yuan Lang promised with a smile.

"And when?" Knowing that the teacher did not teach himself, but only a matter of time, Tan Xiaotian hurriedly asked.

"Well, six years old, but there is a premise, that is, you must be excellent in your studies." Originally, it was just a casual perfunctory little friend, but I didn't expect Tan Xiaotian to believe it, Yuan Lang said after thinking about it.

"Okay, no problem, what does it mean that the teacher is excellent?" Without waiting for Yuan Lang's words to fall, Tan Xiaotian had already agreed, but after thinking about it after agreeing, he asked hesitantly.

"Uh, haha, every day, you want to laugh at me." Yuan Lang was stunned when he heard this, and then laughed heartily - no matter how smart a child is, he is still a child after all, and he doesn't even think about agreeing to what the request means without thinking about it, if this kind of thing is changed to an adult, it must not be said that people are stupid?
