Transmigrating to the Three Kingdoms as Lu Bu: I Have a Pseudo-Apocalypse System

Once outside the palace, Yuan Xi breathed a sigh of relief and said, "Brother, we've finally saved our lives."

Yuan Tan also breathed a sigh of relief and said, "Yes, His Majesty is magnanimous. He didn't kill us and even appointed us as governors. We must work hard from now on and not let His Majesty down."

Yuan Xi asked, "But brother, can those natives really be managed?"

Yuan Tan sneered, "If they can't be controlled, kill them. Kill them until they obey. His Majesty said that those who disobey will be killed without mercy, and those who rebel will have their entire clan exterminated. With that said, what do we have to fear?"

Yuan Xi nodded: "Brother is right."

The two brothers returned to the Japanese island and began to implement Lü Bu's policies.

Yuan Tan, on the island of Benzhou, registered all the natives and organized them into households. Each household was allocated land, but the land belonged to the Han Dynasty, and the natives only had the right to use it. Half of the annual harvest had to be handed over as tax.

The local people were dissatisfied and wanted to rebel. Without saying a word, Yuan Tan killed several hundred people who led the riot and hung their heads on the city gate as a warning.

From then on, the natives of Honshu Island dared not resist anymore and obediently farmed, mined, built roads, and constructed houses.

Yuan Xi did the same thing on Kyushu and Shikoku, killing a group of troublemakers, and the natives of Kyushu became docile.

Yuan Tan also stipulated that if an indigenous woman married a Han man, their children would be considered Han citizens and exempt from half of the taxes. If an indigenous man married a Han woman, their children would also be considered Han citizens and similarly exempt from half of the taxes.

After this policy was introduced, many indigenous women vied to marry Han men. Most of the Han soldiers were single, and seeing that the indigenous women, though short, were gentle and obedient, they also married them.

After several generations, the number of pure-blooded indigenous people on the Japanese islands decreased, while the number of mixed-race people increased. Eventually, everyone identified themselves as Han Chinese, and no one called themselves indigenous anymore.

Those with indigenous ancestry also try their best to hide it and never mention it.

Centuries later, the inhabitants of the Japanese islands opened their history books and saw that it stated: "The original inhabitants of the Japanese islands have become extinct due to their insubordination, decadent lifestyles, death from disease, and natural causes such as typhoons and tsunamis. The current inhabitants of the islands are all descendants of Han Chinese."

After reading it, they nodded, proud to be Han Chinese. As for how those Japanese natives died out, nobody cared.

Of course, these are all for later.

……

In the winter of the 406th year of the Han calendar, in Luoyang.

That winter was particularly cold, but the palace was bustling with activity.

At the Imperial Academy, Liu Hong led his students to accurately measure the law of free fall. They used iron balls of different weights, dropped them from different heights, recorded the time, calculated the velocity, and finally derived the formula for the acceleration of free fall.

Holding a thick stack of experimental records, Liu Hong entered the imperial study and said to Lü Bu, "Your Majesty, after repeated experiments, we have discovered that the speed of a falling object is directly proportional to time, and the distance it falls is directly proportional to the square of time. I dare to name this law: the Law of Free Fall."

Lu Bu took the experimental records, read them through, and nodded in satisfaction: "Good, you've done a great job. Issue an order that the Physics Department of the Imperial Academy should make the law of free fall a key topic, and that all students must learn it."

Liu Hong cupped his hands in greeting: "Your subject obeys the decree."

Zheng Xuan was not to be outdone. He led his students to study buoyancy, conducting experiments in water with objects of different shapes to measure the relationship between the weight of the displaced water and the buoyancy.

After several months of research, Zheng Xuan also concluded: "Your Majesty, our experiments have confirmed that the buoyant force on an object in a liquid is equal to the weight of the liquid it displaces. This is completely consistent with the law of buoyancy that Your Majesty has taught us."

Lü Bu laughed and said, "Good, you've done very well too. Issue an imperial decree that the Physics Department of the Imperial Academy should also make the law of buoyancy a key topic."

Ma Jun continued to make progress. He not only improved microscopes and looms, but also improved new types of water pumps that could use water power to pump water from lower to higher places to irrigate farmland.

When Lü Bu saw the water pump, he was overjoyed: "Ma Jun, your improvement is excellent. It can be promoted throughout the country. From now on, even the land on the hillsides can be irrigated."

Ma Jun said, "Your Majesty, I would also like to improve the steam engine so that it can be used in more places. The steam engine on the ironclad warships is not good enough. I want to make it more coal-efficient and more powerful."

Lu Bu's eyes lit up: "Good, go ahead and do it. Whatever materials you need, I'll have the Ministry of Works supply them to you."

Ma Jun accepted the order and left.

The Imperial Medical Academy also discovered more bacteria using a microscope.

Gibbon observed the feces of dysentery patients and discovered a spiral-shaped worm inside.

Zhang Zhongjing observed the sputum of tuberculosis patients and discovered a rod-shaped worm inside.

Hua Tuo observed the pus from the festering wound and discovered a small, spherical worm inside, which was the Staphylococcus aureus he had previously found.

The imperial physician Ji Ben compiled these findings into a report and presented it to Lü Bu.

After reading it, Lü Bu picked up his brush and wrote: "Different bacteria cause different diseases. Dysentery, tuberculosis, and festering wounds are all caused by bacteria. Issue an imperial decree that the Imperial Medical Academy should research methods to kill bacteria and find drugs that can kill these bacteria."

Yoshimoto accepted the order and left.

In early December, the Imperial Medical Academy discovered that spraying lime water in wards could kill bacteria in the air and prevent the spread of infectious diseases.

The Imperial Medical Academy summarized various sterilization methods and compiled them into a "Hygiene and Epidemic Prevention Handbook," which was distributed to all prefectures and counties across the country.

The manual states: "Drink boiled water, not raw water; wash hands frequently before meals and after using the toilet; do not urinate or defecate indiscriminately; dispose of garbage centrally; filter and settle sewage; disinfect wards with lime water; wipe wounds with alcohol; isolate yourself if you have an infectious disease."

Upon receiving the manual, all the states and counties complied with it.

In the spring of 407 AD, public health conditions across the country began to gradually improve. Although it was not something that could be achieved overnight, fewer people had diarrhea, fewer people had fevers, and fewer people had infected wounds.

After people followed these practices, they found that drinking boiled water and washing their hands frequently could indeed reduce illness, so they gradually developed the habit of drinking hot water.

The Da Han Xun Bao newspaper published numerous articles promoting public health knowledge, and newspaper boys went from street to street, delivering the newspaper to thousands of households.

Seeing these changes, Lü Bu felt gratified.

He knew that to make a nation strong, it was not enough to rely on war or farming alone; it also required science, hygiene, and education.

These things require the efforts of one or even several generations to see results.

But he wasn't in a hurry.

He's still young, only in his forties. He has plenty of time.

More importantly, he possesses a divinely bestowed granary, unlimited storage space, and knowledge that transcends his time.

These are the forces that have enabled him to change the world.

Standing atop the palace tower, gazing at the distant Yellow River Bridge, Lü Bu felt a surge of heroic ambition.

Under the whole heaven, all land belongs to the king. On the shores of the whole land, all people are subjects of the king.

He wants to unify Eurasia. He wants to conquer the whole world.

When that day comes, the banner of the Han Dynasty will be planted all over the world. The footprints of the Han people will be found in every corner of the earth.

And he, Lü Bu, will become the ruler of the entire earth, and his name will be remembered for all eternity.
