The opportunity to make meritorious contributions should be given to those who are in a hurry and have no way, hahaha.

Chen Chu touched his chin, well, this is indeed a problem.

At this time, it was mid-hour, that is, two o'clock in the afternoon.

Maybe it's because the dishes are more than too many dishes, and there are too many stupid hangings, in a short period of time, Chen Chu has almost five thousand spit points in one go, and he is also a little tired, so he plans to just rest for a while, stop watching chess, and help think of a way by the way.

You can't rely on the system for this, after all, the cooldown time is fourteen days.

Sitting in the shade, in front of the chilled fruit, the ice cubes are not seen by the people, there is naturally no shortage in the imperial city, and there are people shaking fans behind, which is still very comfortable.

"The chessboard has to be erected, and the pieces and the board must be large enough to be difficult for people from a distance to see." Li Er said beside him, crossing Erlang's legs.

Chen Chu thought for a while, and suddenly asked, "Sinan, you're not unfamiliar with this thing, right?" ”

"Sinan?" The eldest grandson Wuji and the others repeated in surprise, and suddenly, several people had ideas in their minds at the same time, and the two words Chen Chu opened up the inspiration.

Even Li Er clapped his hands and stood up: "That's right, Sinan, why didn't I think of this thing!" ”

In fact, Chen Chu is not referring to Sinan, that is, the compass itself in ancient China, but to the magnet.

Magnets were called magnets in ancient times, and in the Spring and Autumn Period and the Warring States Period a long time ago, there was a saying that magnets summon iron in the "Lü's Spring and Autumn Period".

If it is an iron chessboard, and then use a magnet chess piece, wouldn't it be firmly attached to the chessboard?

When the time comes, it will be erected, and a big plate will not be able to be seen by many people?

Li Er immediately showed off his thoughts and said his thoughts, triumphant, waiting for Chen Chu's approval.

Chen Chu was a little stunned, and looked at the others who seemed to have the same idea, didn't they know the principle of repulsion of the same pole and attraction of different poles?

He said speechlessly: "Everyone, let's not talk about where to find such a large iron chessboard, and you have to draw lines, polish it messily, it's very troublesome, and if the chess pieces are all magnets, so many of them, when you get close, you will open the other chess pieces." ”

"If it's a different pole, it will also suck the surrounding chess pieces over, besides, the chessboard is big, the chess pieces can't be small, if the iron chessboard is easy to find, where can you find it on the big magnet? It doesn't want one or two, but dozens. ”

Chen Chu's words directly made everyone speechless,, how can it be very reasonable.

"We can replace the chessboard with wood, the carpenter is still very good at doing this kind of work, and when the time comes, we can make the chessboard as big as possible, and simply make it two people long and two wide, so that as long as it is not too far away, it will definitely be able to see clearly."

"Then, because the front piece has to be made very large, we also use wood, and the middle is empty, so that it can reduce its weight."

"Finally, we put a hook on the back of the chessboard and hung a magnet on it, and the chess pieces with the wooden planks on the front were made of iron on the back, so that the light pieces could be attracted by the magnets at the back."

"In this way, not only the material is very small, but also simple and lightweight, and only two people in the front and two people in the back can be manipulated."

"For example, if a horse eats a cart, then we just have to take the cart away, and then fly the horse to the position before it, and then take off the magnet behind the horse's original position."

"Another example is the intrusion, for example, the cannon is going to move forward, so let's first give it the place where it wants to fly, hang a magnet behind it, and then fly the cannon over, and then cancel the original magnet."

"How, simple is not simple, in this way, there is a huge erection chessboard and chess pieces, and the simple operation method is very smooth, not only everyone can see it, but the operator can quickly restore the fall of the chess pieces, so that the viewer does not need to wait for the cutscene, and the idea of watching chess will not be interrupted."

Everyone: "......"

This person is a devil, why is the way they think is so bad, and this person is so clear-minded?

The more people think about it, the more right it becomes, isn't this method perfect?

At that time, they will no longer have to stand stupidly in the stands and look down, obviously Mao can't see it.

The chessboard vision is no problem, the distance is too far, the distance is no problem, there may be a problem with the viewing angle, and now as soon as the chessboard comes out, everyone only needs to look at the chessboard as big as the wall, and the chess player will walk on it.

Isn't that beautiful?

Jiujiang and Cui Shi glanced at Chen Chu with admiration, this thing would be very simple when analyzed, but they couldn't think of such a way before.

Chen Chu is naturally not really so smart, he can only say that he lives in modern times and thinks differently from the ancients, he has seen more, thought more, and experienced more, so he naturally has many ingenious ideas.

It's not worth mentioning, he will not be presumptuous, the credit is his, and he will not take any credit from himself.

"It's easy to say, haha, it can be done overnight today, and tomorrow we can watch the real chess game!"

Li Er's heart was full of joy, he was originally not interested in playing chess, but if it was such a novel and intuitive way of viewing, then he would have to appreciate it and help Datang discover talents.

He suddenly remembered something: "By the way, Chen Chu, last time you told Lao Sun that you wanted to set up a new department to be responsible for these physical exercises and other affairs, have you ever thought about what to call it?" ”

What's the name?

Is Guo Jia's General Administration of Sports okay? I'm afraid you won't be able to accept it.

If this kind of thing is mentioned to Li Er by others, Li Er will directly be a blank eye, damn, the order of the court is good, you have to create a new department and give you face.

But since it was said by Chen Chu, and it was also the level of the five eunuchs of the Nine Temples, it didn't hurt to set up one.

If Jiang Zi said that he, the emperor, would be addicted to sports in the future, wouldn't there be an excuse? For example, isn't it very good to guide the work, to have fun with the people, to select talents for the country, and so on?

"I'm not very good at this, so I suggest you discuss it together."

Chen Chu laughed dryly, he was going to be able to come up with a name, and he had already arranged a good name for a mess like potatoes.

Jiujiang covered his mouth and smiled: "Second brother, do you know, the name of Chen Chu's gymnasium is Tiance Gymnasium, and his naming level, I think it is no different from ordinary people." ”

Tiance Stadium?

Li Er and they really didn't know about this, and when they heard the name, everyone looked around in surprise.

Friend, do you know why Admiral Tiance has not had a second since His Majesty? This is a hit.

You don't shy away from it, and you rush to come up with this name...... But well, if it is the name given by Lord Chen, I think His Majesty will not only not feel guilty, but will be very excited.

Everyone looked at Li Er, didn't they, although Li Er was very restrained now, his mouth was crooked.
