The delivery guy traveled back to the Anti-Japanese War era with the bandit hunting system. The Japanese were not only his enemies but also points. He could exchange weapons for killing the Japanese, and exchange weapons for weapons to kill the Japanese. A cycle that made the Japanese miserable was born.

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!!!
