Chapter 264 Engine
After coming out of the palace, Li Ang immediately rushed home non-stop, preparing to compile medical school textbooks.
He already has a part-time job in the Imperial Medical Administration, and he has the full right to write textbooks, and he doesn't have to worry about Qiu Quan and others' opposition—the previous preparations were not in vain.
A large number of cases have proved the correctness of anatomy and surgery.
For example, the reason why intravenous injection is chosen for injection is because the drug can flow back to the heart through the venous blood, and then flow through the whole body through the heart to be distributed to the liver and other places.
The arterial blood pressure is high, injection is difficult, and bleeding is easy. And the position of the artery is deep, the wall of the tube is thick, and the lumen is thin, so it is difficult to insert the needle.
For example, debridement and drainage, vascular suture, trauma suture, fracture recovery, etc., all have relative advantages over previous medical techniques.
Yu State is at its peak, and has a high degree of acceptance of new culture and science.
In addition, Li Ang is already an authoritative person, with the halo of the little medicine king, it is not difficult for him to add this textbook or even a subject in the Imperial Medical Office.
‘Now there are wards and medical schools, the only difference is that the common people can afford to see a doctor. '
Li Ang thought silently, even in a highly developed foreign world, public medical care is still the most difficult social problem.
If all medical expenses are borne by the government, the pressure is too great,
And if public health care is transformed from a public welfare undertaking to a market-oriented one, dominated by capital, it will inevitably lead to new problems.
For example, expensive medical treatment, excessive medical treatment, tense conflicts between doctors and patients, etc.
Li Ang doesn't want to see at all that the sickroom system he has worked so hard to build becomes a money-making knife for the common people.
‘In the final analysis, it is still necessary to increase productivity first, so that the people and the country of Yu can become rich. Otherwise, no matter how good the systems of wards and medical schools are, they are just castles in the air. '
Li Ang, who was writing the textbook, paused for a moment,
Tomorrow, let’s go to Dr. Su Feng’s place to have a look. Tantai Leshan said before that their engine has made another breakthrough.
———
After three months, he returned to the school.
Li Ang listened to Lang Langchen's reading voice from the supervisory building, smiled and walked along the tree-lined path, crossed the covered bridge over the lake, and came to the gate of the patent office.
Before stepping into the patent office, I heard the deafening rumble inside and Su Feng's laughter.
what happened?
Li Ang covered his ears, walked into the door in doubt, and saw that everyone in the hall was wearing furry earmuffs,
On the ground in the middle of the hall, there is a strange-looking mechanical creation that makes loud noises.
The machine is close to the height of half a person, with a dense and complex structure of gears, chains, and belts on the surface.
Through the half-disassembled casing of the device, you can still see the more complex pistons, connecting rods, and crankshafts.
"Oh, Risheng, you are here."
Su Feng, who was wearing pink-haired earmuffs, saw Li Ang appearing, stepped forward and moved the joystick of the machine, making the machine stop, and said with a smile, "How about this fifth-generation engine?"
"Five generations?"
Li Ang was slightly taken aback, "Iterating so fast?"
You must know that when he left Chang'an, the patent office was still working on the first generation of engines, and in just three months, it has already changed to the fifth generation?
"hey-hey."
Su Feng grinned, did not explain anything, took off the pink hair earmuffs on his head and put them on the table, and asked Ou Zhiyuan and other students to reinstall the engine casing on the ground,
He beckoned and took Li Ang to the office.
"In the past three months, I have devoted myself to researching the engine. I haven't written many letters to you. I'm really sorry. Here."
Su Feng poured a cup of tea with his thoughts, took a few steps forward, came to the middle of the messy office full of books, and stretched out his hand to uncover a piece of tarpaulin.
Crash.
The oilcloth fell to the ground, revealing more than a dozen large and small mechanical creations, each of which has a slightly different shape.
"These are the results of this period of time."
Su Feng rubbed his palms, and introduced with great interest: "First of all, the first generation engine, you still remember,
But most of the wind forces are in conflict with each other inside the wind chamber, which is consumed and the power is insufficient.
So we followed your proposal and invented the second generation, using water as a substitute.
Burn through the fire talisman to generate heat, heat the water into steam, and use the steam to push the piston.
This efficiency is more than 50% higher than before, but the fire talisman burns too fast, even if it is a talisman of a monk in the cloud patrol realm, it can't last for a quarter of an hour.
Unless it is for a rune master like Tantai Siye to make a move. "
“.”
Li Ang leaned forward and carefully observed the second-generation engine, his heart beating violently.
But not to mention, Su Feng is indeed one of the best geniuses in Yu State in the past hundred years,
This second-generation engine is no different from the steam engine in the memory of the other world. It only needs to replace the talisman with coal.
Su Feng continued: "Therefore, I invented the third and fourth generation engines.
The former used the ingenious puppet technique of the former Sui Dynasty, which can replace and trigger the talisman by itself, extending the running time of the machine from two hours to one hour.
The latter uses double talismans on the basis of the former.
There are both fire talismans to provide heat and condensation talismans to draw water from the air, so there is no need to keep adding water to it.
The overall running time has increased to six hours. "
Twelve hours? !
Li Ang was slightly stunned. The steam engine that can run non-stop for twelve hours can already meet most of the production needs at this stage, and it cannot be praised too much.
"However, it is still too troublesome to maintain, and once it is running, it cannot be stopped, otherwise the whole talisman will be wasted."
Su Feng couldn’t hide the smile at the corner of his mouth. Ordinary people, fools and fools could not understand the power of this invention.
On the contrary, it would make him happier to be surprised and admired by a smart person of the same level as Li Ang.
"So, there is the fifth-generation engine."
Su Feng smiled and took out a large volume of blueprints and handed them to Li Ang.
"This is."
Lian Ang looked at the cumbersome and obscure mechanical structure on the drawing, as well as the runes engraved on the metal plate, his face was filled with astonishment and astonishment, "Shensha Yunlu?"
"Shh, keep your voice down."
Su Feng quickly waved his hand, and said softly: "The fifth-generation engine largely abandoned the ordinary talisman, but directly engraved the god-evil cloud talisman from the pre-Qin period on the metal plate.
The technique of talisman originates from witchcraft. As the oldest talisman, Shensha Yunlu has a more direct communication with heaven and earth.
It was replaced by the talismans of later generations only because it was difficult to control and prone to uncertain consequences.
The aura of heaven and earth is not a pool of stagnant water, but will flow and change like the wind.
The **** and evil cloud on the metal plate can absorb the weakest flowing aura of heaven and earth like a funnel to drive the engine to run.
Only need to paste a basic talisman to trigger it.
After experiments, a monk listening to the rain can write ten talismans that meet the requirements a day.
The efficiency of the engine activated by each talisman can replace hundreds of laborers and farmers. "
"hiss"
Li Ang took a deep breath, and the shock in his heart was beyond words.
He was not surprised by the output power of the Shensha Yunlu engine. Su Feng’s design is to intercept the tiny aura when the aura of heaven and earth flows, which is similar to a wind turbine to some extent.
Its power has an upper limit, and it cannot be compared with the monks in the cloud patrol.
However, driven by the aura of heaven and earth
Such a design is completely different from the memory of the foreign world.
From the steam engine, skip the internal combustion engine, gas turbine, jet engine and other stages, and enter the era of "reiki machine",
Technology tree completely develops in another direction.
