Li Bai stretched out his left hand and turned over the white paper on the table, and was not lightly touched by the exam questions.

"Since Zhuge Sage created the wooden ox and flowing horse, this thing has been popularized and convenient for the transportation of people's goods. Ask candidates to try to make a sketch of a new means of transport. ”

"No wonder he gave me a ruler and a carbon lead. ”

Li Bai felt that the exam questions in this world were really unusual, he thought that he would only take the holy classics, but he didn't expect that he would also take the questions of the engineer class, which can be regarded as his own loneliness, after all, his predecessor had only participated in the children's exam.

"Transport, bicycles!"

A flash of inspiration flashed in Li Bai's head, isn't this a ready-made means of transportation? If the transportation volume is large, it will be changed to a tricycle.

"Yes, just draw a bicycle, one for two or three wheels. ”

Li Bai secretly rejoiced, fortunately, he was an engineering man in his last life, and this simple mechanical drawing was still difficult for him.

Li Bai laid out a blank piece of paper, picked up carbon and lead with trembling hands, picked up a wooden ruler with his left hand, and said that he would do it.

First make a rough plan of the length of the shaft, measure it, and then use the memory in the brain to sketch the rough outline one by one.

"It hurts!"

Li Bai bared his teeth, his arm was at least cracked, and he had to find a Lang Zhong to take a look after the exam.

However, Li Bai's body has experienced the baptism of vitality after all, and its strength is higher than that of ordinary beasts, and it can still stand up.

Plus two wheels.

"No! There is no plastic in this world, what can be used as tires? wood? without use, and iron will not work!"

Li Bai began to have a headache, he didn't think of this problem earlier, if the tires are made of brittle materials, they will pedal very hard, which will greatly reduce the role of the bicycle.

"What should I do?"

Li Bai stood up anxiously and paced around the room, his forehead was covered with beads of sweat, thinking that he had a headache, he had to combine the technology of the previous life with the situation in the present life in order to hand over a perfect answer sheet.

"Then I'll make two means of transport?"

Li Bai thought that he could make wheels out of wood first, and when the society developed in the future, he would naturally create a material like rubber, and it would not be too late to change it when the time came.

"That's all!"

Li Bai made up his mind, the development process of history can not be achieved overnight, at least there is a process, although there are all kinds of strange abilities in this world, but ordinary people are still the majority, only by improving the productivity of ordinary people, Datang's national strength can have a qualitative leap.

"That's something that a bike can't do. ”

Li Bai shook his head, he had already made a decision in his heart, after all, Datang is strong, and his own safety can be guaranteed, and now he is embattled, if Datang is broken, it will be a cold mouth.

"Throughout the modern history of the previous generation, the most important reason why the British Empire was able to defeat the three countries of Spain, the Netherlands, and France, which were the former naval powers, was the role of social productive forces, and the political system was secondary. ”

The most important thing is that with his current ability, he has no right to speak about the political system, and can only wait until later, but he can promote the development process of Datang's social productive forces.

"At the heart of it all was the steam engine, the engine of the first industrial revolution. ”

This is not off topic, after all, the production of railways is also a means of transportation, and it is an unprecedented development, a train with a few carriages, its transportation capacity is higher than that of many powerful literati, plus the role of the steam engine is far more than this, and it can also develop workshops.

"Let's finish the bike first. ”

Li Bai made a decision, so he set about it, first drawing a simple picture of the bicycle, and then drawing the most important drive system decomposition diagram aside, adding a lot of text to explain the working principle of the chain driving gear.

"Whew! ”

Li Bai stretched his waist and looked at the incense in the room, which was already burning a quarter.

"Look at what the others are doing. ”

Li Bai directly used the sac firefly to improve his eyesight.

"Ouch. ”

Li Bai covered his eyes, a little swollen and painful, only then did he realize that there seemed to be an invisible light curtain at the door of his room, which would block his gaze when he tried to look out.

"I'm really idle. ”

Li Bai secretly complained in his heart, but fortunately, the invigilator didn't seem to notice what he had just done.

"Let me think about the steam engine. ”

Although Li Bai had learned the steam engine, he had only studied it superficially, which was not too fine.

"No matter what, I just make the core schematic diagram, and I believe that there will be capable people in the Gong family and the Mo Saint family who can use this schematic diagram to create a real steam engine. ”

"Steam engine, ...... after boiling water"

Li Bai first wrote a brief description of the steam engine.

"Lord Chen, junior Lu Zheng came to visit. ”

Outside the Chen Mansion, Lu Zheng was with a few servants, and on the other side, it was Chen Wenyin.

"Quick, move all the gifts in. ”

As soon as Lu Zheng finished speaking, several servants moved a bunch of gifts into the Chen Mansion.

"Why should the virtuous nephew bring any gifts when he comes to play?"

Chen Wenyin smiled elegantly, but there was black and white light in his eyes, trying to suppress the anger in his heart.

He didn't know that Lu Zheng's goal was his daughter, and it was not because he liked his daughter, but because of the Chen family's status above the court.

After all, although Lu Zheng's father is the prime minister, the reason why his arrogance is so arrogant is entirely because of the Lu Sheng family behind him, but the Chen family is different Chen Taiwei is in charge of the command of the world's soldiers and horses.

"Uncle said and laughed, it's just a little courtesy, why bother, hey, why didn't you see Sister Sicun?"

Lu Zheng said "humbly and politely", not to mention, if people who don't know see the current Lu Zheng, they will really be confused by appearances, thinking that he is an elegant literati.

"Let's go first. ”

Chen Wenyin welcomed Lu Zheng in, and the door slowly closed.

"That's how the steam engine works, and I'm going to make a sketch. ”

Li Bai wrote for half an hour, and finally finished writing the working principle of the steam engine, as well as the simple structure.

Later, he made a sketch of the steam engine, which is actually the principle of the lever, a vertical lever, under which are layers of waterproof paper, and then below is a boiler, when the water in the boiler is boiled, a large amount of water vapor has nowhere to go in the confined space, and can only push the piston made of waterproof paper to rise high, so that the lever rises, after condensation, the gas decreases, and the lever goes down again.

With the addition of a device, the lever and the power wheel can be connected.

"Next up are the locomotives and the tracks. ”

Li Bai breathed a sigh of relief, he had finally completed the most difficult project, and there was still a quarter of the time left, which should be enough.

Li Bai used his soul painting skills to draw a very abstract sketch of a locomotive, followed by the train tracks and each carriage.

Time also passes by minute by minute.

"Knock knock!"

The bell rang again, and Li Bai just stopped writing.

"Candidates take a break and we will mark all the exam papers as soon as possible. ”

A voice was transmitted to Li Bai's ears through the vitality, and then, Li Bai saw that his exam paper actually rose into the air and flew out of the room.

"This time, we will directly use the power of the Dao Palace to mark the papers, and the speed will be very fast, and all the test papers will be divided into four grades: A, B, C, D, and only the first class will be considered qualified. ”

"Hey!"

Several examiners shook their heads as they looked at the flying exam papers.

"Nothing new, nothing new!"

The white-haired old man who was in charge of signing up directly criticized that today's scholars are too rigid in their thinking and too difficult to innovate, and if this continues, it will be difficult for the human race to gain a foothold in the ten thousand worlds.

"I don't know how that Li Bai boy is doing, don't let me down. ”

All the examination papers flew into the main hall of the Dao Palace, and the enshrined holy images emitted a faint halo, and the aura of the Holy Dao was permeated.

"Get out of here. ”

The white-haired old man took the lead out of the main hall, and several people followed closely behind and took the door by the way.

"Li Lun, the new carriage, Ding, etc. ”

"Zhang Wu, Xinmu Niu Liuma, Ding, etc. ”

Above the main hall, there are constantly golden characters appearing, marking the grade of each test paper.

"Hey!"

Those candidates whose results were announced all sighed, and then were directly teleported out of the Dao Palace by the power of the Dao Palace.

As soon as these people went out, they were surrounded by water, and everyone wanted to know the questions of this exam.

"This time the questions were too difficult. ”

When everyone learned about it, they couldn't help but complain.

Li Bai was also anxiously waiting in the room of the Dao Palace, this time a total of two hundred and twenty candidates were almost finished, and they had not yet read their results.

Only ten people got the first grade, which is enough to see the difficulty of Xiucai exam promotion.

After the results of the two hundred and nineteenth people were read, there was silence in the main hall of the Dao Palace, and Li Bai's results were not read at all.

"Ah, has it really been fulfilled?"

Li Bai had long thought of a possibility, these saints might have a strong feudal mentality, and they couldn't see their own advanced thinking.

"What about Li Bai?"

The white-haired old man couldn't help it first, and rushed directly into Li Bai's examination room, but saw that Li Bai was still sitting there, and he was the only candidate left in the entire Dao Palace.

When Li Bai saw the old man, he had to shrug his shoulders and spread his hands helplessly.

"Brother Chen, congratulations!"

The ten members of high school were congratulated by many readers, and the fact that they were able to make the cut was enough to prove their ability.

"It's all gone. ”

After some pleasantries, everyone thought that no one would come out again, so they prepared to leave.

"Li Bai, bicycle, train, super first, etc!"

"What?"

Everyone stopped, looking at the golden words on the top of the main hall in disbelief, they had never seen anyone get the super first grade!

"Hahaha!"

Li Bai couldn't help laughing, he was really embarrassed just now, for fear that he would fall off the list.

"Congratulations, young man!"

The old man also showed a smile, people of his age, fame and fame have long been downplayed, what really makes him happy is to see some capable juniors, these later generations are the hope of the future of the human race.

"Specially grant Li Bai the baptism before the saint. ”

A loud voice came from the hall, and in the next moment, Li Bai disappeared out of thin air.
