The sophon from the Three-Body plane and the two-dimensional solar system, for some reason, traversed planes and arrived in the Earth plane of 1981, merging with the consciousness space of the protagonist, Wang Jiankun. With the help of the sophon, a super artificial intelligence, and its ability to generate 3D models of objects it encounters and control the movement of certain elements, the protagonist develops the productivity and technology of the current plane, leading Earth's civilization to upgrade, and ultimately guiding humanity to the stars and the universe.

In Constantinople in 1272, an empire was fading into twilight. A soul from the future awoke in the body of Andronic II, the gravedigger of Rome. Distilled spirits, movable type printing, cannons, fleets… He wielded technology and reason as his sword, tearing a bloody path through the old world of theocracy and ignorance. From the first pot of gold in the royal workshops to the roar of the Anatolian industrial region; from the undercurrents of the Sicilian Vespers to the cannon fire of the battles on the Black Sea and the Mediterranean; from the iron hooves conquering the Turks to the white sails of the New World. —The old world was burning, and a new order was being born. This time, Byzantium was not the final chapter of history, but the beginning of civilization.

As the king of an arms empire, Tang Mo unexpectedly perished and transmigrated to a completely different world, where he unexpectedly obtained an Arms King System.

In this backward world, Tang Mo relies on the abilities granted to him by the system to drive the development of the entire world.

After all, the desire for conquest is the driving force behind the progress of civilization, and life has been constantly evolving between attack and defense for millions of years...

So, selling assault rifles to these archers and training knights to be tank crewmen... there's nothing wrong with that, right?

A crystal from three thousand years in the future, a wish for love and peace. This is a lighthearted and humorous story about leading humanity to advance their technology, fight aliens, and ultimately build peace.

Yin Shou transmigrated to the world of Investiture of the Gods and found himself as King Zhou of the Shang Dynasty! Faced with various schemes, Yin Shou awakened the Human Emperor Merit System! He could use his knowledge from his previous life to nurture the country and its people! "The host invented iron smelting, gaining 100,000 merit points. The Shang Dynasty's national strength has increased dramatically, and its fortune has increased by three hundred years!" "The host invented the Four Great Inventions, including papermaking, gaining ten million merit points!" "The host invented trains, airplanes, and Italian cannons, gaining one hundred million merit points! The Shang Dynasty is invincible!!" Yin Shou pointed his sword at the heavens: "I have benefited the country and its people; I have achieved sainthood through merit! Who dares to challenge me?!"

If you were to travel back to the end of the Ming Dynasty in 1628, what would you do? The Jurchen barbarians outside the Great Wall had risen, and in twenty years they would march into the Great Wall, leaving hundreds of millions of Han Chinese dead at the hands of foreigners. The Ten Days of Yangzhou, the Three Massacres of Jiaxing, the "Retain Your Hair, Lose Your Head" policy, the literary inquisition, and nearly two hundred years of isolation from the outside world, countless humiliating treaties, preferring friendship to domestic slavery, and ceding 1.74 million square kilometers of territory, an area roughly three times the size of France. China, despite its resources and the goodwill of its neighbors, paid 1.95 billion taels of silver in compensation to the powerful nations, a world record, but not a glorious one. [Tea Head]

From the Victorian throne to the shadow of the Cold War Iron Curtain, this is an epic of the Kingdom of Romania spanning a century.

Eder, a modern man, was reborn as the Crown Prince of Romania. With his visionary foresight, he refined oil, strengthened the military industry, and promoted reforms. He made precise bets amidst the turmoil of two world wars, transforming the small Balkan country into a regional power that attracted worldwide attention.

However, the real test began after his abdication. His son, Michael I, struggled to protect the legacy left by his father under the Iron Curtain of the Cold War. Faced with Soviet pressure and the ambitions of powerful ministers, the crown was destined to fall. But the Hohenzollern bloodline never abandoned its homeland. Decades of exile allowed them to forge the national spirit overseas; in times of great upheaval, they returned to rebuild the nation's backbone as uncrowned figures.

This is not only a royal legend, but also an immortal epic of a nation's struggle for survival, strength, and self-discovery amidst a century of upheaval in modern times. How did a family that lost its crown achieve eternity in another way? The answer lies on this land they deeply love.

He invented a revolutionary technology—the "thought device." It can convert imagined scenes into high-definition digital video, reducing the cost of a big-budget film from hundreds of millions to millions. For this, he and his company had to single-handedly fight against a united front from an entire industry. His technology company is called "Huashang," and this is a story about how technology can revitalize a nation. This prosperous era is as you wished…

My name is Zhang Yang. I can see the repair information of items in the courtyard house, and I can get rewards for repairing them.

Just as I was getting ready to be a happy repairman, I saw the repair notices above the heads of the residents in the courtyard.

...

My name is Qin Huairu, and I am a widow who has been widowed for two and a half years.

The stool in my house is broken, and I was going to ask the repairman in the yard to fix it, but he told me that I'm the one who really needs repairs.

My name is Xu Damao, and I am an older single man who has been infertile for many years.

My table at home is broken, and I was going to ask the repairman in the yard to fix it, but he told me that I'm the one who really needs repairs.

Lou Xiao'e, Yu Li, Qin Jingru...

"I am an honest and hardworking person..."

He traveled through time and became the Prince of Lu in the Ming Dynasty. After his death, Zhu Yuanzhang gave him the posthumous title of Huang.

This identity is so tempting!

It is perfectly reasonable for me to be unconventional and indulge in pleasure!

Above him was his benevolent father, Emperor Taizu of Ming, who spoiled him, and below him were his ministers who thought he was ridiculous.

So, I am a spendthrift, absurd, and shameless, but I am a good prince.

Thus, the imperial seal was returned, the ironclad ship went out to sea, and the national treasures entered the Ming Museum.

Thus, wherever the sun, moon, mountains and rivers shine, it is all Han territory!

Good father, please indulge me again.
