"No... No, no... I don't ride in a four-wheeled carriage, it's too bumpy. Shen Wuwan waved his hand desperately and refused Ma Hanshan's invitation.

"Yes, yes, the four-wheeled carriage is not only bumpy but also dangerous, you can't turn around, the horse is about to turn over when you pull up, don't sit, don't sit." Zhang Zi also waved his hand desperately.

What they said was indeed right, because the four-wheeled carriage he knew was just adding two more wheels to the carriage of the two-wheeled carriage, because the four-wheeled carriage landed on the ground, and there was less "shock absorption" of the cart-pulling livestock, and the transmission of the road surface was richer, which was indeed more bumpy than the two-wheeled one. Moreover, because the previous four-wheeled carriage did not have a steering system, if the force of the carriage pulling the carriage was sufficient, it was easy to pull over when turning.

"Is there something wrong with your eyes, do you see carefully, my chariot is the same as you know? Alas, I was going to hand over a big deal to you, but now it seems that I have to find someone else. Ma Hanshan raised his middle finger and gently waved it from side to side and said, "You... It's too inferior, not only stupid, but also self-righteous, read more books. ”

Yes? Read more? You kid didn't read the Four Books and the Five Classics.

Is it really different? Shen Wuwan and Zhang Zi were stunned. yes, this carriage... How is it so high? Well, it seems different, the front two wheels are smaller, the rear wheels are larger, and, well, the wheels are iron? What a waste, to make wheels out of iron, ouch, this body is also made of iron, and copper, oh my God... What a loser.......

In this world, the production of metals is extremely low, so copper and iron are very important, they are not only materials for weapons and living utensils, but also materials for currency.

In Dasong, although the amount of iron coins is not much, but it is still in circulation in the market, in some poor rural areas, silver is very rare, and it is very good to see copper, most of which are iron.

Therefore, Shen Wuwan and Zhang Zi couldn't help but shout about waste when they saw Ma Hanshan's four-wheeled carriage, almost all of which were made of copper and iron.

Not only did they say it was a waste, but they were also worried that two horses would not be able to pull at all, and that a cart made of iron would be so heavy that they could pull it.

Of course, they didn't know that this carriage was an epoch-making product for the Da Song Dynasty, because to build this car, the tile cylinder village broke through and invented more than a dozen technologies.

Not to mention the invention of loose gum, the invention of the suspension system, the invention of the steering system, etc., there is also something that greatly improves the force transmission, which is definitely a breakthrough.

That's the bearing.

The principle of bearings has been applied for a long time, but no one has made a real bearing.

The reason why the tile cylinder village can be invented is also thanks to Ma Hanshan's "guidance", and it is also thanks to Ma Hanshan that he received Liu Guisan, Zhang Machinery and other best "blacksmiths" and "craftsmen" in the world, otherwise, even if there are Ma Hanshan's ideas and "drawings", it is impossible to turn them into products and apply them so quickly.

With bearings, the efficiency and power of horsepower conversion will be greatly improved for a single carriage. For example, it may be possible for a horse to pull a thousand catties of things, but with this bearing, a horse can pull two thousand catties or three thousand catties of things, and it will not be more laborious than pulling a thousand catties.

In the modern society of Mahanshan's previous life, just because the manufacturing process of a bearing is backward from others, countless wealth will be scraped away from others every year, and because the process of a bearing is a little backward, it is often stuck by people, resulting in many advanced design things can not reach the manufacturing or can not meet the design standards.

The bearing is definitely an inconspicuous, but very important invention.

"Business? What a business... No, you can't give the business to someone else... Why don't you just take the carriage, I can't sit yet...... The first to react was Shen Wuwan, he took three steps and two, pulled the door like a monkey and got into the car.

Yes!

Seeing this, Zhang Zi was about to lift his feet to get on the car, but he heard an exclamation from Shen Wuwan in the carriage, and hurriedly stopped and asked Brother Shen what was wrong.

"Too... It's so comfortable... The chair can be made ...... like this. Shen Wuwan spoke in surprise from the carriage.

"Chairs? What happened to the chair, Brother Shen ....... Zhang Zila opened the door and asked.

"What a comfortable chair ......." Shen Wuwan in the carriage was like a child, and said with a buttocks.

"How comfortable?" Zhang Zi felt that Shen Wuwan was a little... It's a bit silly, such an old man, what has he never seen, what is there to be surprised about a chair?

But, of course, he got into the carriage and sat down, and he was so comfortable that he screamed.

The sofa in the carriage is placed vertically and horizontally, and there are several foldable ones in the middle.

The sofa is made of leather, which is not the key, the key is the spring under the seat cushion, this structure is a bit like the modern Simmons mattress structure, but this is not enough, the leather cushion placed on it is still particular, because it is an air cushion.

That's right, an inflatable cushion.

Dense springs, coupled with inflatable seat cushions, everything is for shock absorption, for comfort. Ma Hanshan praised Zhang Machinery's initiative, this play, the effect is really great.

"Oh my God, how can it be so soft... Heck, this backrest is also very soft... Brother Ma... This... What is this stuff made of? Water? Or gas? Shen Wuwan pinched the cushion and said.

"First of all, you have to make progress, you have to be in line with science, this is not called a chair, it is called a sofa... Shopkeeper Shen, didn't I tell you what a sofa is? Alas, it really doesn't grow. Mahanshan's voice came from the "cab" in front.

"Hehe... Ah... This... This glass window is so ...... transparent. Zhang Zi looked here and there like a child, and when he lifted the curtains, he suddenly found that the scenery outside the car was very clear, and he couldn't help but be amazed.

"If you don't read, that's not glass, that's glass. The definition of our science gate is that the transparent is called glass, and the impermeable is glass, you remember. Ma Hanshan Zhang 147 called to get into the car, then dropped the reins and called to drive... Start the wagon.

Boom!

The horse's hooves knocked on the stone-paved road, the sound was very crisp, and a four-wheeled carriage that surpassed the perception of people in this era drove on the streets of Lin'an City.

It's not upside down? It's really not upset at all, Shen Wuwan and Zhang Zi dropped their jaws in shock, this... It's impossible, it's not at all... Haven't you driven yet? Zhang Zi turned his head to look out the window, no, he was driving.

"Zhang Caidong, look at ......." Shen Wuwan pointed to the teacups on a few sons... The expression was like seeing a ghost, the teacups on the table were filled with tea, and the full cups of tea were only slightly rippling, but they didn't overflow, which was incredible.

In modern times, this is not a big deal at all, but in ancient carriages, this kind of thing is really shocking, and Zhang Zi and Shen Wuwan's eyes are about to fall in shock, which is really incredible.

Not to mention them, even Ma Hanshan, who was sitting in the "cab", was shocked, he really couldn't imagine that Zhang Machinery could actually achieve such a degree of shock absorption without pneumatic tires.

However, he immediately worried that the eucommia gum in the middle of the wheel would soon lose its elasticity under heavy pressure.

"Two, I'm going to speed up." Ma Hanshan pulled down the copper cylinder above and said.

This is also the initiative of Zhang Machinery, the sealing of the carriage is very good, between the "cab" and the back compartment, unless you shout hard, it is not audible, so Zhang Machinery invented the copper pipe "intercom system".

"Can you turn?" Zhang Zi's voice came.

Ma Hanshan laughed, then raised his whip and snapped a guy on horseback.

Boom .......

For the two horses pulling the cart, the cart was effortless, so the whip was drawn, and they stretched out their waists and galloped wildly.

The face of 147 squatting in the "cab" is changing, too fast... It's too fast, can you turn it, can it turn over?

That's right, 147 is indeed squatting at the foot of Mahan Mountain, because the "cab" is only designed for one person's position, but next to the foot, there are some positions, and he can learn to "drive" here.

Listening to the sound of hooves to know how fast the car was, by the standards of this era, it was already a speeding speed, but fortunately, there were not many people on the streets at this time, and the bells on the carriage were very loud, and people avoided this strange carriage early on, otherwise, there would have been an accident.

"It's so fast... Brother Zhang, this carriage is really fast, ....... Shen Wuwan exclaimed as he looked at the rapidly retreating scenery on both sides of the car.

"It's... It's so fast... And it's so stable... Turned... You can really turn a corner, oh my... The corners are so steady... That's great... That's great... I'm going to buy one of these wagons ....... Zhang Zi gasped and said.

"I... I also buy... Oops, it's been to Qingbo Gate so soon? Shen Wuwan exclaimed.

It's really to Qingbo Gate, because Ma Hanshan's purpose tonight is to go to the Happy Building outside Qingbo Gate to get Wu Guangjie's silver ticket, and pull Shen 50,000 Zhang Zi and the two, in addition to letting them experience the four-wheeled carriage, it is just to let them cover up, otherwise, although he has been "dominating" Happy Lou for half a year, Ma Gongzi, who has never come to Happy Lou, suddenly came, which is really eye-catching.

When Mahanshan went out of the city, the Lin'an Mansion and the Imperial City Division both received a report that someone was driving a strange car in Lin'an City regardless of the safety of the people, and the speed was extremely fast, and the patrolling palace guards and the guards of the government could not catch up with .......

The soldiers patrolling in the city, there are guards from the front division of the palace, and there are also guards from Lin'an Mansion, they are generally patrolling on foot in the division, of course, there are also horseback riders, but the interval between the cavalry patrols is larger, and they do not meet the carriage of Mahan Mountain.

Horse-drawn carriage galloping? What kind of carriage? Who's so bored to gallop in a carriage? Doesn't that make people dizzy?

A strange car? How is it strange? Don't know whose car it is? Bastard, go check it, find out right away.

The Imperial City Division, the Imperial Front Division, and the Lin'an Mansion all issued orders to immediately find out what the strange car was and whose it was.

At this time, in front of the Happy Building, there was a group of people around, they were all watching this strange four-wheeled carriage, I haven't seen it, this car can really run? Ma Hanshan and Zhang Zishen Wuwan have entered the Happy Building.

"The three guest officers are ......." Welcoming... Well, the general brothels of Qinglou are greeted first by big teapots, but the happy building is a little different, there is actually a "welcome", Ma Hanshan and the three of them entered the door and a woman greeted them like willows, but before she finished speaking, she was gagged by a silver ticket.

"I want the No. 1 room, the best banquet on the table, and a few elegant girls, but I am not allowed to apply grease and powder." Ma Hanshan said, holding a large silver ticket.
