After coming out of the palace, Li Ang immediately rushed home without stopping to prepare for the compilation of medical school textbooks.
He already has a part-time job at the Imperial Medical Office, and he has full authority to write textbooks, and he doesn't have to worry about objections from Qiu Quan and others - the previous preparations were not in vain.
A large number of cases prove the correctness of anatomy and surgery.
For example, the reason why injections are given intravenously is because the medicine can flow back to the heart through the venous blood, and then flow throughout the body through the heart and be distributed to the liver and other places.
However, arterial blood pressure is high, making injection difficult and prone to bleeding. Moreover, the arterial location is deep, the wall is thick, and the lumen is thin, making it difficult to insert a needle.
For example, debridement and drainage, blood vessel suturing, trauma suturing, fracture recovery, etc. all have comparative advantages over previous medical techniques.
The Yu State is at the peak of its prosperity and is highly receptive to new culture and science.
In addition, Li Ang is already an authoritative figure and has the aura of the Little Medicine King. It will not be difficult at all for him to add this textbook or even a subject to the Imperial Medical Office.
‘Now we have hospitals and medical schools, we just have to make it affordable for the people to get medical treatment.’
Li Ang thought silently, even in a highly developed alien world, public health care is still the most difficult social problem.
If all medical expenses were borne by the government, the pressure would be too great.
And if public health care changes from a public welfare undertaking to a market-oriented one and is dominated by capital, it will inevitably cause new problems.
For example, medical treatment is expensive, excessive medical treatment, tension between doctors and patients, etc.
Li Ang doesn't want to see the hospital system he worked so hard to build turn into a money-grabbing knife for the people.
'In the final analysis, we must first improve productivity and make the people and the country rich. Otherwise, no matter how good the system of hospitals and medical schools is, it will only be a castle in the air.'
Li Ang, who was writing textbooks, paused.
Tomorrow, let’s go to Dr. Su Feng’s place. Tantai Leshan said before that their engine has made another breakthrough.
——————
After three months, I returned to the academy.
Li Ang listened to Lang Langchen's reading coming from the supervising building, smiled and walked through the tree-lined path, crossed the covered bridge over the lake, and came to the door of the patent office.
Before I even stepped into the patent office, I heard the deafening rumbling sound inside and Su Feng’s laughter.
What's wrong with this?
Li Ang covered his ears and walked in the door in confusion. 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 nearly half a person tall, with a dense and complex structure of gears, chains, and belts on its surface.
Through the semi-disassembled shell of the device, you can still see the more complex pistons, connecting rods, and crankshafts.
"Oh, Risheng, you're here."
Su Feng, who was wearing pink fur earmuffs, saw Li Ang appear, stepped forward and flipped the machine's joystick, causing the machine to stop, and said with a smile: "How about this fifth-generation engine?"
"Five generations?"
Li Ang was slightly startled, "Is it iterating so fast?"
You must know that when he left Chang'an, the patent institute was still researching the first-generation engine. In just three months, it had been upgraded to the fifth-generation engine?
"Hehe."
Su Feng grinned and did not explain anything. He took off the pink hair earmuffs on his head and placed them on the table, asking Ou Zhiyuan and other students to reinstall the engine casing on the ground.
He waved and took Li Ang to the office.
"I have been studying the engine with great concentration in the past three months. I have not written many letters to you. I am really embarrassed. Here you go."
Su Feng poured a cup of tea with his telekinesis. He took a few steps forward and came to the middle of the messy office filled with books. He stretched out his hand and uncovered an oilcloth.
Wow.
The oilcloth fell to the ground, revealing a dozen mechanical creations of various sizes, each with a slightly different shape.
"These are the results of this period of time."
Su Feng rubbed his palms and introduced enthusiastically: "First of all, it's the first-generation engine. Do you still remember it?
The principle of the first generation engine was to use wind charms to attract strong winds and push the piston back and forth.
However, most of the wind power conflicts with each other inside the wind chamber and is consumed, resulting in insufficient power.
So we followed your suggestion and invented the second generation, using water as an alternative.
The fire talisman burns 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 the talisman of a monk in the Cloud Patrol Realm cannot last for two quarters of an hour.
Unless we let a magician like you, Tantai Siye, take action."
"..."
Li Ang stepped forward and carefully observed the second-generation engine, his heart beating loudly.
But aside from that, Su Feng is indeed one of the top geniuses in the Yu Kingdom in the past hundred years.
This second-generation engine is no different from the steam engine in the memory of another world. It only needs to replace the talisman with coal.
Su Feng continued: "Therefore, I invented the third and fourth generation engines.
The former uses the clever puppet technique of the former Sui Dynasty, which can change and trigger the talismans on its own, extending the running time of the machine from two clocks to one hour.
The latter, based on the former, uses double talismans.
There are both fire talismans that provide heat, and water condensation talismans that draw water from the air, eliminating the need to add water all the time.
The overall operating time has increased to six hours."
Twelve hours?!
Li Ang was slightly stunned. A steam engine that can run continuously for twelve hours can already meet most of the current production needs. It cannot be praised enough.
"However, it is still too troublesome to maintain, and once it is running, it cannot be stopped, otherwise a whole talisman will be wasted."
Su Feng couldn't hide the smile on his lips. Ordinary people and foolish men and women couldn't understand the power of this invention.
On the contrary, surprising and admiring a smart person of the same level as Li Ang would make him even happier.
"So, there is a fifth-generation engine."
Su Feng smiled and took out a large roll of drawings and handed them to Li Ang.
"This is..."
Li Ang looked at the complicated and obscure mechanical structure on the drawings, as well as the runes engraved on the metal plates, and his face was filled with surprise and uncontrollable surprise, "God's evil cloud?"
"Shh, keep your voice down."
Su Feng quickly waved his hand and said softly: "The fifth-generation engine has largely abandoned ordinary talismans, but instead engraved the divine evil cloud talismans from the pre-Qin period directly on the metal plate.
The art of talismans originated from shamanism. As the oldest talisman, the Shensha Yunlu has a more direct communication with heaven and earth.
It was only because it was difficult to control and could easily lead to uncertain consequences that it was replaced by the talismans of later generations.
The spiritual energy of heaven and earth is not a pool of stagnant water, but will flow and change like the wind.
The Shensha Yunlu on the metal plate can act like a funnel, absorbing the weakest flowing spiritual energy of heaven and earth to drive the engine.
You only need to paste a basic talisman to trigger it.
After experiments, a monk in the Listening to Rain Realm can write ten talismans that meet the requirements a day.
And the working efficiency of the engine started by each talisman can replace hundreds of laborers and farmers."
"Hiss..."
Li Ang took a deep breath, his heart was shocked beyond words.
He was not surprised by the output power of the Shensha Yunlu engine. Su Feng's design intercepted the tiny spiritual energy when the spiritual energy of heaven and earth flowed. It was similar to a wind turbine to a certain extent.
There is an upper limit to its power, which cannot be compared with the monks in the Patrolling Cloud Realm.
But, driven by the aura of heaven and earth...
This kind of design is completely different from the memory of another world.
From the steam engine, skip the internal combustion engine, gas turbine, jet engine and other stages, and enter the era of "Aura Machine".
The technology tree is completely developing in another direction.
