Li Chunfeng glared at him!
Today, I must demand an explanation for my level of mathematics!
He glanced at the messy numbers and symbols written on the wooden board, as well as a simple triangular calculation formula. He could not help but frown slightly. It seemed...
I can understand a little of this thing?
" This is called the X-axis, and this is called the Y-axis. When the Divine Fire Flying Crow flies in the air, it presents an arc-shaped curve…"
Seeing that Li Chunfeng had taken the bait, the green sparrow hurriedly stood on the stool and explained to him loudly.
Li Chunfeng frowned as he held his brush and leaned on the table. He grabbed a piece of papyrus and began to calculate.
Familiarity, practice, comprehension, mastery…
The foundation of Chinese civilization was the study of Yi, and Li Chunfeng was a master of the study of Yi. Mastering the study of Yi was equivalent to mastering the most fundamental principles of the world.
He began to use Yi Xue to reverse deduce the formula. Not long after, his knowledge of parabola and trigonometer functions had reached the level of comprehension.
Looking at Li Chunfeng skillfully drawing the X-axis and Y-axis on the blueprint with a brush, Li Tai had to admit that Li Chunfeng was a genius!
Only such a genius could deduce the secrets of heaven and write such a wonderful book as the Pushing Back Map.
"Lord Taishi, the Turkic cavalry has appeared three hundred paces in front of us. If we use the Divine Fire Ravens to bombard the area, how should we adjust the angle?”
Li Tai asked softly.
Li Chunfeng did not answer. Instead, he scribbled on a piece of paper. Finally, he nodded slightly and cupped his fists at him." Your Highness, according to my calculations, it should be fifteen degrees."”
"Very good. Now that our army is on the mountain, the enemy has appeared 150 meters below the mountain. The height of the mountain is 40 meters.”
Li Tai and Li Chunfeng were completely immersed in the world of mathematics and did not care about anything that happened around them. Li Chunfeng became more and more familiar with trigonometric-functions and parabolas. In the end, he even reached the point where he could calculate the results without using papyrus!
What a freaking genius!
Li Tai was full of admiration for him!
"See you tomorrow, Lord Taishi!" Li Chunfeng counted until it was dark. Only then did he leave the general supervisor, feeling unsatisfied. Green Sparrow waved goodbye to him. Tomorrow, without his instructions, Li Chunfeng would definitely come early to check on the morning and continue his unfinished lessons!
"How is it, nephew? Uncle has recruited a talent for you!”Li Daozong boasted, and the green sparrow smiled." Uncle, don't talk nonsense. He was about to leave. Fortunately, I used a difficult question to attract his attention, so he stayed to learn mathematics!”
"Aiyaya, you don't hit the face when you hit someone, and you don't expose the truth when you scold someone!”Li Daozong's face reddened as he complained.
The 3,000 elites selected from the palace guards and the black-armored army were also ready. In the prison, the production of the Divine Fire Flying Crow and grenades was carried out at full speed. However, they lacked enough copper, so the green sparrow's cannon construction plan had to be temporarily put on hold.
"Your Highness King Yong, this is the mirror you asked this lowly one to make.”A white-haired old craftsman walked over and handed a small box to Li Tai. Li Tai opened it and saw an exquisitely decorated monocular.
The lenses were made of crystal. They were crystal clear, pure as water, and flawless. It fully demonstrated the superb craftsmanship of these craftsmen!
It was just that the production was too low. The two of them spent a month to make one!
He put his eyes on the lens and slowly extended the lens. The distant shadow slowly became clear and finally stopped.
He saw the chief eunuch, Wang De, teaching two little handmaidens a lesson for their mistakes. Two little eunuchs were watering the flowers and plants with water bottles, and two butterflies were dancing…
"Nephew, what good stuff is this?”Li Daozong asked curiously when he saw him holding a long cylindrical object and twisting it around.
The green sparrow had many of these strange things, from firecrackers, grenades, to divine fire flying crows. He had seen a lot of fireworks.
" This thing is called a telescope…" Green Sparrow handed the telescope to her uncle." It can see things far away…"
"Oh, what is this?" Li Daozong took it and directly placed his big head on his eyes. He was shocked to find that his precious daughter, Li Xue Yan, had actually become a small ant!
"It's upside down!" Li Tai corrected him, not knowing whether to laugh or cry.
"Wow, it's really clear!" Li Daozong hurriedly came over and gestured towards the distance. Needless to say, he could clearly see things three miles away from him!
"This thing is really good. Nephew, give it to uncle!”Li Daozong asked shamelessly.
"Two hundred taels of gold for one. Uncle, take the money!”Li Tai didn't stand on ceremony and directly demanded an exorbitant price!
"Take it!" He directly took off a Four-clawed Shell Dragon Jade Pendant from his body and threw it to the green sparrow. The green sparrow took it and took a look. It was carved from a whole piece of suet jade. Its price was definitely more than 200 taels of gold!
"This isn't worth much!" The green sparrow pursed her lips and put the jade pendant into her pocket as she said unhappily.
Li Daozong was stunned. He searched his waist for a long time, but only managed to dig out two copper coins. He chuckled and scratched his head." Why don't you come to my house and take a look? You can move whatever you like. How about that?"”
The green sparrow pursed her lips.'We're decent people, not bandits!'
" If it really doesn't work out…" Li Daozong glanced at his delicate daughter and giggled," Why don't I mortgage the Snow Goose to you as your wife?!"”
Uncle, how can you be so shameless!
"Ding! Warning to the host. The shameless Li Daozong has been detected. He wants to use his daughter, Li Xueyan, as collateral to obtain the finished telescope. The shameless index is 5 stars. Please stay away from such a person, please stay away from…"
(Give me a set of everything! Now I have gathered another 500 votes. I will give you more tonight.)
