Scientific travel, reasonable logic, and development of two worlds reveal the fundamental nature of the world.

Han Yun's father disappeared inexplicably, and his own business failed. He wanted to live a miserable life but traveled through time inexplicably. He wanted to enjoy life by reselling goods between the two worlds, but he found that his father also traveled through time. He said that he would enjoy life through time, but it turned into a miserable journey to find his father. Fortunately, he had a beautiful woman in his arms and money in his account, which was some compensation. As he slowly developed, he discovered the truth of the world. The end of metaphysics is science, the end of science is theology, the end of theology is philosophy, and the end of philosophy is... nothing!

Obedient little maids, pretty courtesans in brothels, modern strong women, famous generals who have intruded into the Three Kingdoms, and century-old gangsters are all under his command.

This book is unusual, with a slow pace, slow farming, and logic. You can't just travel through time and space in ancient times. You need a pass to enter the city, and you need a recommendation to be an official. Although instant noodles are rare, they can't be exchanged for the empress. No matter how good your kung fu is, you are afraid of the kitchen knife. Watch the plot without thinking, and think with your brain, what is our universe?

If you just like the mindless fun and repeated face-slapping routines, you may be disappointed.

This is a practical and scientific guide and handbook for time travel! Explore the truth of the world's existence.

The most important thing is that no one should read the last part, right? You thought it was a double-penetration low-level martial arts book, but it is actually a SLG game book, or maybe a doomsday wasteland book, but in essence it is a hard science fiction book from beginning to end!!!

The protagonist transmigrates into the body of the son of a marquis in another world, inheriting the marquisate's title, developing the marquisate's territory, leading surrounding nobles, fighting against his own kingdom and neighboring countries, and ultimately becoming a grand duke. The protagonist has no system, no special abilities, and no harem; he conquers the world solely through his 21st-century knowledge and millennia-old Chinese military wisdom.

A blood-stained contract, a mountain of gold waiting to be mined, a precarious kingdom. He is an engineer, a foreman, the last hope of all the oppressed. He is an ambitious man, a capitalist, the most unstable piece on the chessboard of the nobility. In his left hand is a blueprint for overturning the world, in his right is the soft hand of his daughter. Vand, no, Edwin VanCleef, will use steel and concrete, gears and levers, to reshape the order of this world. "Truth lies only within the range of siege guns. And I am responsible for defining that range."
