Seeing this, the people of the country, who were still skeptical, did not understand the information leaked in this, and shouted loudly, and the sound of the woods could be heard several miles away. Pen, fun, pavilion www. biquge。 info

Although the children did not understand what their fathers or elders were shouting, they understood the excitement and jumped and shouted. Of course, the movement of people will also arouse the sounds of the animals, the barking of the donkeys, the barking of the dogs, the mianmian of the sheep.

Lu Di, who has been holding Qi Jinggong's hand, saw that Ji Ran used a variant version of the sine theorem method to calculate the height of the big tree, and he was also very happy in his heart. Second, his own rude arrogance and side-knocking inspired the progress in the history of mathematics in this era, although this step is a small step, but it is a big step in that era, so I am happy.

In order to dispel the last doubts in people's hearts, Qi Jinggong asked the Chinese people to find a random tree and let Ji Ran measure it, but the measurement result was almost not much different from the actual height of the tree. At this time, the Chinese people are convinced that the principle of light and shadow must be correct.

Even good scholars began to coax Ji Ran to hand them over methods and principles, and Ji Ran helped him, and he started the first large-class teaching in the history of the Spring and Autumn Period on the snow on the high platform.

If there is any doubt, everyone asks questions, and Ji Ran answers them all.

So a strange scene appeared on the white snowfield, and everyone sat on the snow around Ji Ran to listen to the teaching. Although the weather is cold, people's hearts are hot!

Liang Qiu saw that it was not early, so he secretly arranged for Ai Kong to build a pot stove near here. Of course, the children didn't want to listen to this esoteric calculation, but played in the snow with Lu Di.

Although those children knew Lu Di's identity, but children were children after all, after playing for a while, everyone no longer had a fear and started a snowball fight, this time it was difficult for Zhong You, Zhong You saw that there were children around Lu Di smashing, anxious eyes glared, the children were scared, but I don't know which child who was not afraid of the sky and the earth took the lead in smashing the snowball on Zhong You's body, Zhong You could only stare dryly, okay, this time, those children saw that these five big and three thick beards only had these "skills" to greet the snowball, bangbang, After a while, Zhongyou was smashed into a snowman, but he could only be angry, many of these little guys are the sons of doctors, where is the background of people's power? Besides, an adult can't compete with children.

Seeing that Zhongyou was smashed, Lu Di led his newly recruited subordinates to fight back. A big snowball was about to smash on Lu Di's head, and suddenly a child rushed out and blocked it, Lu Di took a look, and suddenly tears of gratitude flowed up, only to see the snowball hit the child's right eye, and suddenly the city had an eye, and after the child knocked off the snow, the first thing he said when he turned around was "Childe, are you okay?" ”

Lu Di patted the little boy's shoulder with emotion and said, "Little brother, what's your name?" My name is Tu Tu, don't call me Childe, we will be friends from now on."

Although the little boy looked wooden, his eyes and eyebrows were heroic, and he smiled brightly and said, "Childe, do you remember when you were building a road and getting mutton steamed buns, you once knelt down and talked to an old man?" ”

"Huh? Tu Tu remembers, you are, you are, Tu Tu remembers, you are the grandson of the old man, right, right? Lu Di suddenly remembered the scene of the old slave crying with his two grandchildren in his arms, and immediately recognized the little boy in front of him, and he was happy that he was jumping in the snow.

The child nodded seriously, and then seemed to think of something and said, "Childe, don't you know, my grandfather and I are not slaves in our family anymore, my father made great contributions in suppressing the Tianbao rebels and repelling the Jinyan coalition army, and now he has been promoted to the rank of track commander?" Managed, managed, managed a lot of people! ”

Lu Di's tears of sadness burst forth when he heard this, everyone is human, why are some people born to be kings, and some people are born to be cheap, isn't everyone different? They are all rats between heaven and earth.

Lu Di and he hid in their position under the cover of the children, and the two chattered and said something incoherent. The kid forgot Lu Di's initial question, he saw that his side was suppressed by the children on the other side, looked at the terrain, and the other party's formation, and his eyes rolled and said, "Childe, I have an idea, as long as..."

After listening to the little boy's idea, Lu Di was overjoyed, and felt that this little boy was not ordinary, he followed the little boy's strategy, and gave orders to his group of little brothers, and all the little boys had the backbone, and they immediately did things differently.

Lu Di took some children and continued to fight with the other children, and snowballs flew wildly. And the little boy took another group of children and quietly slipped away to Gaogang Snow Valley.

Half an hour later, Lu Di received the signal from the little boy, and led a group of boys to retreat to the high snow hill, and the boys on the other side saw that the enemy was afraid to retreat, and they were bold, crawled out of the position, and chased wildly while smashing.

Lu Di and his boys finally retreated to the high post after suffering a snowball on their backs, only to see that suddenly the children led by the little boy pushed out a huge snowball from behind the high hill and pushed it down, and the snowball rolled bigger and bigger along the slope of the high hill.

The children who came to chase were stupid, and when they looked at the huge snowball rolling in front of them, they turned around and ran backwards in fright. On the high post, Lu Di and his subordinates laughed, and then Lu Di waved his little hand, and all the children went down the mountain like tigers, and the snowballs threw at the other children's children, and suddenly the children, some of them were scared and cried, they wanted to surrender, but the snowballs were still chasing them, and some accidentally slipped and fell to the ground, and did not avoid the snowballs that were getting bigger and bigger, and were immediately pressed over.

The whole scene was extremely lively, Lu Di stood on the hill, facing the cold wind, his chin was raised, if he wore a big red cloak at this moment, it would be perfect, what is high-spirited, what is pointing the country, this is!

The cries of the children on the other side woke up the relatives who were studying there, and they all turned their eyes to this side. When they looked back, they happened to see the picture of the big snowball chasing wildly, the children scattering, and Lu Di staring at the world.

Qi Jinggong saw that he was happy, and the energy that was originally immersed in the ocean of knowledge was gone, Kong Qiu sighed and said to himself, "Man, what a strange animal!" They crave knowledge and etiquette, but as soon as they meet the string of their own bloodline, they will all collapse! Knowledge and etiquette are so vulnerable to it! ”

Ji Ran smiled helplessly, stood up in front of everyone one by one, and the onlookers hurriedly returned the salute, and then ran to their children to see if they were injured?

On the snow, when the sun began to go downhill, Aikong's rice was also ready, it was still mutton steamed buns, and all the Chinese people present had a big steamed bun and a bowl of mutton soup per person. The crowd ate deliciously.

Lu Di and the children ate very deliciously, one was because of their mood, and the other was that they were really hungry. Lu Di put a piece of mutton in the bowl of the little boy who helped him, "Thank you today, if it weren't for your strategy, Tu Tu and they would have been smashed all over the body."

The boy did not refuse the piece of mutton, and after taking a sip of the soup, he took a bite of the meat and squeaked, "Many... Thank you Childe, well, delicious! Well, that's right, Childe, hiccup, I'm called, called, hiccup, Zhang Mengtan".
