Chapter 61

The current situation is very strange. Li forget you doesn't like Li Er. Li Er also sees Li forget you as a bastard.

For a moment, the two stared at each other for a long time in the main hall of Zhang Liang's house. They both felt that they didn't like each other.

Although Li forgets worry, he knows that the man with a curly beard must be a powerful man in the Tang Dynasty, he doesn't want to fulfill his heart. It's not natural to refuse. Opening a sky high price will offend people to death. We have to find a way to deal with this boastful man with curly beards.

As soon as he turned his eyes, he saw the chessboard of the bearded man playing chess not far away and couldn't help laughing.

Li forgot to worry and bowed: "since the husband wants to buy the picture of Luo God from the enemy, it's natural. But the enemy is a grain merchant. I wonder if the husband can accept it?"

Hearing the speech, Li Er nodded and agreed. His enemy is a grain merchant. It's natural that grain is better than copper money. It's very reasonable.

Qiu Kun was stunned when he heard the speech. He looked up at Li forgetful and wanted to say something, but when he thought of the beating he had received in front of Zhang Liang's house, he immediately closed his mouth again.

"Xiao Lang, how much food do you want?"

Li forgot to worry. He smiled and pointed to the elephant chess board not far away: "I don't want much. Just fill that chess board."

His words stunned everyone in the main hall, full of food on the chessboard? What does that mean?

Li niangyou continued to explain: "please put one grain of rice in the first grid, two grains in the second grid, four grains in the third grid, eight grains in the fourth grid, and so on. The number of grains in each grid is twice that of the previous grid. Just fill these 64 grids, and I want so many grains. Can you accept it?"

These words made the ministers and Li Er laugh. The Li Xiaolang was not greedy. He gave a picture of Luo God with a little rice grain. Is this a favor to Li Er?

Cheng Yaojin secretly whispered to Qin Qiong, "does the little boy recognize his majesty? Otherwise, how can he sell the painting so cheaply?"

"It's hard to say. Maybe it's not bad for him to think of the drunkenness that day. The little boy is smart and knows how to sell his Majesty's face. When his Majesty's anger subsides, it will be good for him." Qin Qiong guessed so.

Not only do Cheng Yaojin and Qin Qiong have such ideas, but many important officials who have participated in the qujiangchi poetry fair also have similar ideas. They think this is Li forgetful's move to calm Li Er down by stepping down the steps.

Even Li Er thought it was pleasing to see the boy.

"Ha ha, since Xiao Lang said so, I'm not polite. I'll buy the painting and do it at the price you said." Li Er laughed.

He turned to Zhang Liang and said, "Zhang Qing, lend your family a stone of grain."

Zhang Liang naturally nodded and agreed. There was a trace of regret in his eyes. Unfortunately, he missed such a perfect picture of Luo God.

If it wasn't Li forgetful to present the picture today, if Li Er didn't attend his birthday party in micro clothes, this picture should become the heirloom of Zhang Liang.

But now that Li Er has a crush on it, even if Zhang Liang is domineering, he won't have the idea of this painting.

Soon, the servants in Zhang Liang's house brought a stone of rice and began to put rice grains on the chessboard according to Li forgetful's statement.

All the ministers smiled and said nothing. Others bet on each other to guess whether a stone of rice is enough. Anyway, we are not in a hurry. We just watch the servants slowly count rice grains and have the right to amuse themselves.

Only Li Qieyou sneered in his heart. Hey, a stone of rice, that's a dream!

This is the problem of "summation of proportional series" that junior middle school students will have in future generations.

There are so many grains of rice in 64 squares on the chessboard that "the 64th power of 2 minus 1". The result is 18446744073709551615 grains, 180 billion trillion grains of rice.

Li forgets to worry about remembering that later generations have seen it on the Internet. People who have leisure and egg pain have weighed it. One kilogram of rice is about 60000 grains. If you really want to install this proportional series, it will take 280 billion tons to fill the chessboard.

What is this concept?

The global rice production in the next year is only about 500 million tons, 280 billion tons, which is basically more than the total rice production planted in human history.

Li Er can't give so much rice even if he sells pants.

Li forget worry is simply using advanced knowledge to crush the powerful Tang Dynasty. This kind of intelligence crush feeling that everyone is drunk and I wake up alone is really cool, which makes the corners of Li forget worry's mouth turn up.

In the main hall, the servants were still counting the rice grains, and the accounting room of Zhang Liang's family helped count them with arithmetic chips.

The abacus was not invented by the Tang Dynasty at this time. It was a computing tool that appeared only in the Northern Song Dynasty. Arithmetic chips are a pile of small sticks of the same length and thickness, which are arranged and counted in vertical and horizontal arrangement.

The cashier in Zhang Liang's house had just calculated the 20th chessboard grid, and he was already sweating. The 20th chessboard grid needed to place more than 500000 grains of rice.

With the passage of time, the ministers and Li Er in the main hall also found something wrong. How can you count the rice?

Li Er immediately asked people to calculate how much rice they needed to put.

Immediately, a servant moved out of the scale and began to weigh the rice grains. Another minister skilled in mathematics began to send people paper, pens and calculation chips to calculate how many rice grains needed to fill the chessboard with Zhang Liang's accounting room.

The time of one incense stick, the time of two incense sticks... The ministers who calculated the figures with calculation have become sweating, but the figures they calculated are getting larger and larger.

The person with the fastest progress can only calculate the 26th space on the chessboard. Even if he can't go on, that's an astronomical number.

The servants in Zhang Liang's house also weighed out one or two about 1000 grains of rice with a steelyard. According to this calculation, a bucket of rice is about 190000 grains of rice.

"This... This is impossible. According to this number, there is not enough rice in the whole Tang Dynasty!" a minister skilled in mathematics exclaimed at the calculation chip in front of him.

Li Er and the ministers were surprised and walked quickly to the ministers.

"There's nothing wrong. I've just calculated. I've just calculated 26 squares of the chessboard. That number has exceeded the amount of grain in the whole Tang Dynasty. This is a dissatisfied chessboard!"

Several ministers in charge of calculation were sweating and nodded that the figure was too large to continue to calculate.

When Li Er heard the speech, he didn't know he had been cheated. In his anger, he glared at Li forgetful, who had enough time to sit at the table drinking and eating meat.

"Xiao Lang, please explain to me what this means? Are you teasing me?" Li Er said angrily.

Before, I thought Li forgetting worry was deliberately fooled by the officials under Li Er's steps.

The bastard boy clearly set up his majesty high and then took out the ladder!
