Chapter 823 The fierce Yu Ming girl
Old man Yu Ming squatted on the ground, staring closely at the huge gantry crane on the riverside not far away, his eyes shining brightly.
An extremely tough rope was wrapped around several densely packed round wheels, and under the easy pull of two workers, the heavy objects on the cargo ship docked in the lock were lifted. The cargo was bundled into a fixed cube, lifted effortlessly, and then slid along the door frame beam. The cargo was lifted from the cargo ship in the lock to the shore, and placed directly on a huge flat carriage. See The goods weighing thousands of kilograms were easily pulled away by two strong horses...
The well-informed old Yu Ming has naturally seen things like pulleys, and he even understands the principles of some levers. But the huge gantry crane designed by so cleverly combining pulleys and levers really amazed old man Yu Ming.
"Is this the kind of pulley recorded in the Mohist classic "Mo Jing"? Is this Fang Jun actually a descendant of the Mohist family?"
Old man Yu Ming was shocked and whispered.
There are records about pulleys in the book "Mo Jing" compiled by Mo Zhai and his disciples.
The theory of pulleys is mentioned in detail in the book.
The pulley with a fixed central axis is called a fixed pulley. It is a deformed equal-arm lever that does not save effort but can change the direction of the force. The pulley whose central axis moves together with the weight is called a movable pulley. It is a deformed unequal arm lever that can save half the force but does not change the direction of the force.
Old Yu Ming, who has read hundreds of classics of various schools of thought, naturally read this Mohist classic, so he suspected that Fang Jun was a descendant of the Mohist family that had been lost for hundreds of years...
Otherwise, how to explain Fang Jun’s unpredictable knowledge of mechanisms?
It should be noted that the core of Mohism is not "love for all but not attack", but the mechanism technique that is unique in the world! If he were not a descendant of the Mohist family, how could Fang Jun have such profound attainments in the art of mechanism at his age?
Yu Minglei, who stood prominently behind him, remained silent.
He didn't seem to hear his uncle's doubts. His eyes were a little confused. He looked at the tall gantry crane for a while, then looked at the new sailboats that were going in and out of the shipyard to continuously test data, and then looked down at the cement poured under his feet. The impregnable dock...
Why can that small pulley easily lift goods weighing thousands of kilograms?
Why do new sailboats move faster in a zigzag pattern against a headwind than with a tailwind?
Why is it that a pile of powder-like things becomes as solid as a rock after being mixed with water, sand, and pebbles?
Yu Minglei pursed his lips tightly. He felt that there was a door ajar in front of him. Some things were revealed behind the door, but they were not clear, which made people crazy. He wished he could kick the door open and really take a look at the novel world behind the door...
If we don’t understand these things, how can we talk about the supreme way of heaven?
The old man and the young man each pondered their own thoughts and fell silent.
Brisk footsteps sounded behind me...
Yu Minglei turned his head slightly and saw Yu Mingxue walking quickly, with a cute bulging face and a bad expression.
Yu Minglei asked casually: "What's wrong? You look very unhappy."
It was just a question, he didn't think anything big happened.
The two brothers and sisters have always been very close, and Yu Minglei knows the character of the arrogant girl very well. This girl has an arrogant and willful temperament. She is definitely not as pink, pretty, youthful and beautiful as she looks...
"Hmph!" Yu Mingxue pouted with an angry look on his face: "It's all that Fang Jun. He looks like a dog, but in fact he is a big bastard and a big pervert! How shameless!"
Yu Minglei was shocked. This tone... could it be that Fang Jun was a wolf and took advantage of his sister?
He immediately asked anxiously: "What did that guy do?"
Yu Mingxue clenched her little fists and said angrily: "You are a talker, you are shameless, you are worse than a beast! If he hadn't run so fast, I would have punched his dog's head off with one punch!"
Yu Minglei was not surprised at all. He knew that his seemingly innocent sister was actually a violent maniac. Even if Fang Jun dared to provoke her, he would definitely beat her! What worries him is what did Fang Jun do to make his sister so angry?
This is the old man Yu Ming who is "thinking about life". He was also alarmed by his granddaughter. Hearing this, he asked curiously: "What on earth did Fang Jun do?"
Yu Mingxue's face turned red, a little shy, and she said in a squeaky voice: "This...that..."
After all, Fang Jun's words were too obscene. Although Yu Mingxue did not react at first and could not understand the deep meaning, but after thinking about it for a while, he naturally understood how obscene and obscene it was!
But how can a little girl repeat these words?
Old man Yu Ming was also anxious and asked hurriedly: "You girl, are you talking? Did that guy molest you? Oh, I told you that girls should love themselves and stay away from men, but you just didn't listen. Now, Did you suffer a loss? ”
Yu Mingxue had no choice but to say: "Actually... I didn't do anything, I just talked... it was so unpleasant..."
Yu Minglei was extremely anxious. How come this girl didn't have the refreshing energy she had in the past and was dragging her feet?
"What on earth did he say? Teasing you?"
Being forced by his brother and uncle, Yu Mingxue was ashamed and annoyed. He paused and told the story, and finally said: "What did that guy say, 'How can you win people's hearts if your breasts are not big? How can you level the world if your breasts are not flat?'" Woo, that black boy is playing hooligan..."
Old man Yu Ming clicked his tongue: "'How can you win people's hearts if your breasts are not big? How can you bring peace to the world if your breasts are not flat?' Well, he rhymed with the rhymes and knew his nature clearly. He is indeed a poet with great talent. This statement is really meaningful. The charm is far-reaching..."
Yu Mingxue glared at the old man!
Is this what an uncle can say?
Which side are you from?
Old man Yu Ming realized that he had made a mistake, and immediately grinned in embarrassment, making a gesture of indignation: "Huh, this guy is so brave, he dares to say teasing words, he deserves to die!"
Yu Minglei curled his lips and said: "Although Fang Jun's words are inappropriate, you can't blame him for all the mistakes. If you hadn't been aggressive and persistent in asking, how could he have said such honest words?"
Yu Mingxue's eyes widened and she said angrily: "Yu Minglei, are you my biological brother?"
Seeing that the girl was about to cry, Yu Minglei said quickly and without any stance: "Yes, yes, of course! That Fang Jun is really hateful, how about I go give Xueer a beating as a brother to vent his anger?"
Yu Mingxue said angrily: "No, it's too easy for him! Go and chop off his head so that he can never say dirty words again!"
Yu Minglei sweats profusely...
Cut off someone's head with just one sentence? This girl is simply a wolf girl in sheep's clothing, so cruel! Besides, although Fang Jun is a bit vulgar, what he said is correct...
"Um...beat him a little harder, okay? Killing someone or something, a lot of blood will be shed, it's too cruel..." Yu Minglei had to carefully fight for Fang Jun's chance to survive.
Yu Mingxue refused, stamped his feet and said: "Are you going to kill me or not?"
Before Yu Minglei could reply, his expression suddenly became very exciting.
A voice sounded from behind Yu Mingxue: "What can't be killed? What should be killed? Killing chickens? Haha, Miss Yu Ming is really smart. I have recently learned a method of cooking chicken, and I want to give it to Yu Ming. The girl is going to show off her skills..."
Fang Jun led a group of naval officers to inspect the dormitory construction at the naval port. Unexpectedly, as soon as he walked out of the rows of neatly arranged dormitories, he saw three people from Yu Ming's family talking, and they naturally wanted to come up and exchange greetings.
Yu Mingxue suddenly turned around and stared at the "black boy" who appeared with a pair of big bright eyes! Seeing Fang Jun's innocent look as if he had never done anything, he suddenly felt angry and evil. He scolded: "Just now you were running fast, but now you are seeking death. Suffer death! Who wants to do that?" Eat your chicken..."
The petite body rushed forward, raised her delicate lotus feet, and kicked Fang Jun on the chest. Fang Jun was caught off guard, and even if he was on guard, he couldn't defend himself. He was hit by a kick, his chest felt tight, and his body flew backwards like a cloud.
But now I am standing on the embankment. I flew upside down and fell directly into the water with a "plop"...
Su Dingfang, Liu Rengui and other naval officers looked at each other, then shouted, and several people jumped into the water to rescue Fang Jun. Everyone knows that this little girl looks weak and timid, but in fact her fighting ability is amazing. If this kick is strong enough, will it kick Fang Jun to death? Even if you can't be kicked to death, you will still be choked to death...(End of Chapter)
