The Iron-Blooded Forged City of Qi

In 352 AD, Ran Min was defeated at Xingshan, and Ran Wei was about to perish. Ran Liang, Ran Min's nephew, Ran Wei Zhonghujun - is also a sports medicine student of Beijing University of Physical Education from the 21st century. He woke up in a pile of corpses in Liantai. The javelin penetrating wound on his left shoulder overlapped with the scar from the car accident two thousand years later, becoming an anchor point for time travel. It has no system and no mall. He only has a photographic memory that contains an entire modern civilization: metallography, materials science, sports medicine, military geography, and historical trends. And a body forged from the decathlon training ground - every injury, every healing, gets a little stronger. From the salt-alkali flats on the east bank of the Yellow River to the Iron Wall Valley of the Jiaodong Peninsula; from a snow-white salt boiled with a "return air stove" to a steel knife forged with the "steel filling method"; from a cement wall made of limestone and sand to a power map drawn with animal skins and charcoal strips - He did not call himself king or raise a flag. He only used his geographical identity as a "Qilu native" to build an iron wall in the darkest troubled times. Qian Yan's cavalry came, and horse pits and gravel were waiting for them at the mouth of the valley. The merchant ship from the Eastern Jin Dynasty arrived, and Xue Baiyan and Guangang Dao were waiting for them at the dock. The feet of the refugees have arrived. Porridge, rules, salt and words are waiting for them at the gate of Iron Wall Valley. This is a story about "how to use materials from the industrial age to build barriers to the industrial age." It is also a story about "how to build a world where people can live without killing people when everyone wants to kill people."
