After finding the straight line where the diameter was, Tian Zeng used a rope to draw the inner diameter of the outer ring.

Then put the rope of the inner diameter of the outer ring on the diameter line of the outer diameter of the inner ring, and use the excess part to make the diameter of the roller!

Seeing Tian Zeng's skillful operation, Han Rui was a little suspicious that Tian Zeng was also a traverser!

Under these conditions, the scene in front of me is exactly the same as the problem that appeared in the Olympiad Geometry Competition in later generations: please find the difference in diameter between the two circles without a ruler and a compass!

Han Rui was amazed, Tian Zeng had already carved out more than a dozen small 'rolling logs' - it was very simple, cut them along the small circle drawn, and then cut them until they were smooth.

In addition, what I am doing now is just a conceptual prototype, and it doesn't need to be smoothed at all, just have a general shape.

Han Rui breathed a little heavily: "Tattoo a groove in the middle of the cylinder." ”

Tian Zeng was about to take the knife and stopped in mid-air, stunned in place.

The groove is taken from the top of the rolling wood···

He knew what Han Rui wanted to do!

Putting down the roller in his hand, Tian Zeng used a thin knife to drill holes in the wooden ring.

Seeing this, Han Rui knew that Tian Zeng understood his thoughts, so he didn't say anything more, and looked at the movements of Tian Zeng's hand with burning eyes.

When he was busy until the sunset, Tian Zeng got up and stretched, and threw the finished product in his hand into Han Rui's arms: "But do you want to do it like this?" ”

Han Rui took it, salivating and looking at the thing in his hand, his saliva almost fell to the ground.

It's finally done!

Although the surface of the roller is still a little rough and it is not smooth when turning the outer ring, the meaning has arrived!

Han Rui jumped up and bowed deeply to Tian Zeng: "Tian Gong's skills are really magical!" ”

Taking advantage of Tian Zeng's proud head and stinky fart, he hurriedly said: "How long does it take for iron to be made?" ”

Tian Zeng twisted his sour neck, groaned slightly, and said, "It's not good to drill holes on the iron ring, but I have a way, you can get it in a month." ”

Han Rui hurriedly agreed, and couldn't put it down and played with the 'concept model' bearing in his hand.

At this time, Li Si dragged the listless Sang Ji to the backyard, saluted Tian Zeng, and then greeted Han Rui: "Let's go, the sun is going down, but I'm starving!" ”

Thinking of last night's tragic 'battle situation', Han Rui was thinking about how to refuse, but Tian Zeng's words smashed into his heart like a hammer.

"This thing is not easy to make, it takes a long time, it shouldn't be so cheap, but I will do what I say, as much as I say, 50,000 yuan."

"When you come to pick up your goods, remember to bring enough money."

The joy in Han Rui's heart for the imminent appearance of the bearing suddenly disappeared, and was replaced by endless sorrow.

"A penny is hard to beat a hero..."

What kind of blood mold is this?

After coming to this world, Han Rui, who had almost no concept of money, was entangled by money!

The unlucky ghost of the original owner, because he ran away with his daughter-in-law because he had no money, starved to death; After he arrived, because he had no money to buy food, he could only go up to the mountains to hunt for food; Encountering the Huns in the mountains, the whole village fled to the clouds.

And because he had no money to buy food, Han Rui and his party went to join the army, Zhang Weiyang died, and Han Rui almost died; Most of the villagers also starved to death because they had no money to buy food; After Han Rui killed the Qian slave in a fit of rage, he was once again surrounded by Luan Bu as a guard because of money...

Now I want to find a way to get out, and I want a lot of money!

Ever since he opened his eyes to this world, he has always been running for money and food!

Han Rui finally knew what his golden finger was after crossing over: hunger and poverty!

DE BUFF Permanent Package Check it out!

"It's really sad to have no money..."

In his previous life, although Han Rui was not the son of a rich and powerful man, his family conditions were quite acceptable, and he never worried about money.

I still remember that when I first entered college, my classmates learned that Han's father sold the only three cows in the family in order to provide for Han Rui to go to school, and they were full of sympathy!

Han Rui looked at Banhua who was secretly wiping his tears with a confused expression, wiped the limited-edition ehe cone shoes on his feet, and wondered in his heart: Isn't it just three cows? I still have tens of thousands of sheep at home...

When his thoughts returned to his eyes, Han Rui repeatedly assured Tian Zeng that he would collect 50,000 yuan, and then walked out of the Tian family's courtyard worriedly.

Li Si, who was behind him, saw that Han Rui was not very interested, so he stepped forward to ask.

"What's the matter, the wine you drank yesterday hasn't eased up yet?"

Han Rui remembered yesterday's 'bloody battle', and the alcohol that was still volatile in his stomach surged again, almost 'gushing out'!

Sang Ji reacted even more, directly holding on to the low tree on the side of the street and vomiting wildly.

Han Rui shrunk his neck and said in a low voice, "Brother Li, it's good, let the two of us go today..."

After 'venting', Sang Ji's legs were weak and he walked up to Li Si and squatted, hugged Li Si's thighs exaggeratedly, and said pretentiously: "Big brother~ Don't drink anymore~ If you drink again, you will die~"

Amused by Sang Ji's appearance of playing with treasure, Li Sihe laughed and said, "When did I say I was going to drink?" ”

"It's just a meal~"

When Sang Ji heard this, he shook Li Si's thighs even more exaggeratedly: "You said yesterday that you drank two glasses of thin wine~"

A gag made Han Rui's heart gradually fade: It's useless to worry anyway, let's find a way to go back.

It's really not good to find old man Luan; Anyway, I owe so much, it doesn't matter if I owe a little more, I don't have to worry about a lot of debt!

·

The next morning, waking up from the familiar collapse, Han Rui had a splitting headache.

Yesterday, when the people who said they would only 'eat' came to the restaurant, Li Si picked up the wine jug and drank wildly.

Just drink it, and muttered something weirdly: How can someone with eggs not drink wine?

Ouch, I'm a tantrum!

Hearing this, can Han Rui endure it?

picked up the wine bowl and compared it with Li Si!

The two of them came and went, and Sang Ji sat on wax...

Wolves are afraid of being spineless, and people are afraid of being unsociable; The three of them were at the same table, but Sang Ji didn't drink, coupled with Li Si's flirtatious words, Sang Ji couldn't sit still, so he had to grit his teeth and join the battle.

It was almost the same as the script the day before yesterday, and in the end, the 'battle situation' was still that Li Si was safe and sound, Han Rui only had the brain to remember, and Sang Ji, who was drunk under the wine table, cried and spewed trash talk to the Huns.

"I don't believe Li Laosi's words anymore..."

knew that Li Si's real name was Li Xuan; Sang Ji's real name is Sang Xin, and yesterday's binge drinking was not all for nothing...

Li Xuan is the fourth in the family, and he has been called Li Laosi by his neighbors for a long time, so he is called so by others; Sang Ji is the third in the family, and it is also known as Ji according to the etiquette law.

Liu Bang, the first hooligan leader of the Western Han Dynasty, was 'Liu Ji, the chief of the Surabaya Pavilion in Pei County', before he became 'Pei Gong Liu Bang'.

Looking up at the room, a sense of déjà vu came over me.

But unlike yesterday, Han Rui couldn't stand up anymore...

Just moving his head away from the pillow already made Han Rui feel like his brain was being stirred up by a blender!

Standing up with both hands on the edge of the collapse, he staggered to the door of the guest room, and his weak and hoarse voice was inaudible: "Little·· Two..."

The Xinqi wine shop didn't have much business in the morning, and the little guy happened to be resting on the stairs of the house, and when he saw Han Rui walking out of the door, he hurriedly stepped forward: "What can the son send?" ”

Han Rui cleared his throat and found that it was useless, so he had to continue to say in that ghostly voice: "Yes... No... Yes · Decanting··· Soup..."

The little guy wasted a lot of energy, and his ears were almost stuffed into Han Rui's mouth before he could hear clearly, and hurriedly went downstairs towards the back kitchen.

Waiting for the little servant to bring a bowl of red date soup, Han Rui endured the burning pain in his throat and poured it down, but the headache became more and more intense, so he had to close the door and lie back on the couch obediently to rest.

The moment his head hit the pillow, the pain was significantly relieved, but it still made Han Rui unable to sleep.

In a moment of depression, Han Rui thought about the right thing.

In order to get rid of the bearing, it still needs a production cost of 50,000 yuan to get it; I have to think of another way to make 50,000 dollars in a month.

"What can I do to make 50,000 dollars in a month?"

After thinking about it carefully, if you use ordinary methods, Han Rui's only choice is to borrow usury and go out to sell...

It is impossible for Han Rui to sell his body; As for loan sharks...

My current predicament seems to be that I owe money to others!

borrowed loan sharks to repay debts, Han Rui's IQ has not yet reached minus 100!

If you owe it to Old Man Luan, at least there will be no interest, just pay it back slowly.

After borrowing a loan shark, Han Rui's situation is worse than selling his body!

You must know that the usury at this time is nine out of thirteen...

With an interest rate of close to 50 percent, future generations of online loans that deceive college students will not dare to play like this!

"Money is so cute and hateful..."

Han Rui racked his brains, and he couldn't think of any way to make money quickly anymore - the bearing had already squeezed out his already small knowledge reserves!

As a person who has been in undergraduate school for seven years, it is already a miracle that Han Rui can make bearings!

Thinking of the days of grazing in his previous life, Han Rui secretly wrote down in his heart - although he couldn't do it in the short term, the long-term benefits of animal husbandry were considerable.

Especially in this era of shortage of cattle and meat, the income of a livestock owner is only much more than that of any smuggler.

couldn't think of a way, Han Rui could only empty himself; The flock of sheep in captivity in his previous life flooded into his mind, causing Han Rui to fall asleep amid the sound of bleating.

After two days of coping with the low-level 'hangover candy', Han Rui was able to walk, and he didn't slow down at all!

"This wine is too bad, isn't it?"

In his previous life, Han Rui had secretly drunk decades of aging wine that his father had hidden in the corner, and the smell seemed to still waft at the tip of Han Rui's nose.

The rich aroma of wine makes people drunk without drinking, like being in a fairyland; A small cup in the mouth, with a hint of spicy in the soft taste, flows down the throat into the stomach, and the whole body instantly warms up...

The most important thing is that you won't have a headache when you wake up with a hangover, a comfortable horse!

I remember that in my previous life, a classmate said that the wine was on because there were many impurities?

Thinking to himself, Han Rui sat in the lobby, waiting for the meal to be served, and watched the little servant take out the cloudy wine from the wine barrel.

"Maybe you can try distilled spirits..."
