Great Tang’s Talented Little Landlord

The current situation is very strange. Li Wangyou is not pleasing to Li Er, and Li Er is also not pleasing to Li Wangyou, a bastard youngster.

For a while, the two looked at each other for a long while in the big eyes staring at small eyes in Zhang Liang’s mansion, and both felt that it was not pleasing to look at each other.

Although Li Wangyou knows that this man with beard must be Great Tang’s nobleman, he does not want to follow his heart. Obviously rejecting it is naturally not enough. Opening your mouth for a sky-high price will even offend people to death. You have to find a way to respond to this boasting man with a beard.

As soon as I turned my eyes, I saw the chess board where the bearded man was playing chess not far away, and I couldn’t help but smile.

Li Wangyou bowed and bowed: “Since this Master wants to buy the “Portrait of Goddess Luo” by the enemy, it is natural. But the enemy is a grain merchant. I don’t know if the Master can accept this picture with food. “

Li Er heard this for a moment and he nodded agreed. The enemy is a grain merchant. It is reasonable to ask for food better than copper.

Qiu Kun hearing this was taken aback. He looked up towards Li Wangyou and wanted to say something, but when he thought of being beaten before Zhang Liang’s mansion, he immediately closed his mouth to death.

“Small master, how much food do you want?”

Li Wangyou laughed, pointing to the chess board not far away: “I don’t want much, install that board It’s full.”

His words made everyone in the main hall startled. Filled with chessboard food? What does this mean?

Li Wangyou continued to explain: “Please place one grain of rice in the first grid of the chessboard, two grains in the second grid, four grains in the third grid, and four grains in the fourth grid. Put eight grains in one grid, and so on. The number of rice grains in each grid is twice the number of the previous grid. Just fill these 64 grids so that I need so many rice grains. Is it acceptable for the Master? What?”

These words made both Qunchen and Li Er laugh. This Li Family small master is not greedy. With a little grain of rice, he gave out a pair of “Portrait of Goddess Luo”, which is considered to be sold to Li Er. Is it personal?

Cheng Yaojin even whispered to Qin Qiong secretly: “Does this little boy recognize Your Majesty? Otherwise, why sell this painting so cheaply?”

“Not good said, Maybe he thinks of the drunken scene that day. This little baby is smart and knows that selling Your Majesty is a good face. Looking back, Your Majesty is mad, and it will naturally benefit him.” Qin Qiong also guessed.

Not only Cheng Yaojin and Qin Qiong have such an idea, but many Important Ministers who have participated in the Qujiangchi Poetry Society also have similar ideas. They think that this is Li Wangyou who is giving Li Wangyou the second step. , Let Li Er’s anger.

Even Li Er thinks looking at youngster is a bit pleasing to the eye.

“haha, since the small master said so, then I’m not welcome. I bought this painting, and I will do it at the price you said.” Li Er haha smiled.

He turned his head and said to Zhang Liang again: “Zhang Qing, borrow a stone of grain from your house for use.”

Zhang Liang naturally nodded, he still has a trace of regret in his eyes. It’s a pity that such a perfect “Portrait of Goddess Luo” missed him.

If Li Wangyou did not come to present the picture today, and if Li Er was not in Weifu to attend his birthday banquet, this picture should become his Zhang Liangs heirloom.

But now that Li Er has taken a fancy to it, Zhang Liang will not have the idea of this painting even if he is domineering.

Soon, the servants in Zhang Liang’s mansion carried a stone of rice and began to place rice grains on the chessboard according to Li Wangyou’s statement.

The ministers all smiled, and some people bet each other to guess whether a stone of rice is enough. Anyway, everyone is not in a hurry, just watching the servants slowly pick up several meters, and the right to entertain.

Only Li Wangyou in the heart sneered, hehe, one stone of rice, that is dreaming!

This is the question of “sum of geometric series” for later junior high school students.

There are so many grains of rice in 64 grids on the chessboard “2 to the 64th power minus 1”. The result is 18446744073709551615 grains, which is 180 billion trillion grains of rice.

Li Wangyou remembered that later generations read it on the Internet and someone who had idle pain in the balls said that one kg of rice is about 60,000 grains. If you really want to install this geometric series, it would take 280 billion tons to fill the chessboard.

What is this concept?

The global rice output in the next year will be only about 500 million tons, and 280 billion tons is basically equivalent to more than the total output of rice grown in human history.

With so much rice, Li Er can’t even sell pants.

Li Wangyou is purely using advanced knowledge to crush Great Tang, a group of powerful people. This kind of IQ crushing feeling that everyone is drunk and I am alone is really cool, so Li Wangyou cant bear it. Live upturned.

In the main hall, the servants are still counting rice grains, and the accountant at Zhang Liang’s house is on the side to help with counting chips.

Great Tang did not have an invention abacus at this time, it was a calculation tool that did not appear until the Northern Song Dynasty. Counting chips are a bunch of small sticks of the same length and thickness, arranged in two vertical and horizontal arrangements to count.

The accountant in Zhang Liangs mansion has just calculated the twentieth checkerboard grid, and has already been brow beaded with sweat. The twentieth checkerboard grid needs more than 500,000 grains of rice. .

As time went by, the officials and Li Er in the main hall also found that something was wrong. How can this rice be counted more and more?

Li Er immediately let people start to calculate how much rice needs to be placed.

Immediately, a servant moved out of the steelyard and began to weigh the rice grains. In addition, ministers skilled in Mathematics began to send people to send papers and pens and counting chips to work with Zhang Liang’s accountant to calculate how many rice grains are needed to fill the chessboard.

5 minutes of time passed, and the time for two sticks of incense passed… Those ministers who used calculators to calculate numbers have become sweaty, and the numbers they calculated are getting bigger and bigger.

The person with the fastest progress can only count the twenty six squares on the chessboard, which is already an astronomical number.

And the servants in Zhang Liang’s mansion also used a steelyard to weigh one or two about 1,000 grains of rice. Based on this calculation, a bucket of rice is about 190,000 grains of rice.

“This…this impossible, according to this number, the entire Great Tang’s rice is not enough!” A minister who specializes in Mathematics looked at him and exclaimed.

Li Er and the ministers were both shocked and walked quickly to the ministers.

“There is nothing wrong. I just calculated it. I just calculated the chessboard twenty six squares. That number has exceeded the total number of grains in Great Tang. This is simply a chessboard that is not full! “

Several ministers in charge of calculations all brow beaded with sweat, all of them nodded saying that this number is too large to continue calculations.

Li Erhearing this, I dont know where I was fooled. He was furious and fiercely stared at Li Wangyou who remained calm and composed while handling pressing affairs, who was sitting on the table drinking and eating meat.

“Small master, please explain to me, what does this mean? Are you playing with me?” Li Er said angrily.

I thought that Li Wangyou was deliberately giving Li Wangyou down to the courtiers who were dumbfounded.

This bastard youngster clearly raised Your Majesty high, and then fiercely removed the ladder!
