In 228 BC, by the Yishui River.
An alchemist was chased to a cliff by the Qin army and jumped - fell off the cliff, fell into coma, and was rescued by veteran Wang Jian.
His real name is "Lu Sheng", but he comes from more than two thousand years later. On the sheepskin map in his arms was drawn a secret that kept the First Emperor awake at night: the original so-called "world" was just a corner of the world; but two thousand years later, China would suffer humiliation - ceded territory, indemnities, unequal treaties, and was beaten again and again for falling behind.
In order to repay the favor of saving his life, he presented the steel frying method, cement formula, and steam engine blueprints; in order to change history, he took the risk to show off to the First Emperor - Zhao Gao usurped the throne, Hu Hai subjugated the country, the Five Husbands disrupted China, the Eight-Nation Allied Forces, and the Anti-Japanese War...
The First Emperor did not kill him.
The First Emperor said: "I don't want the elixir of life. I want the flag of Qin to be planted on every inch of land on this piece of paper."
From that moment on, an alchemist forgotten by history and an emperor misunderstood by later generations jointly embarked on a gamble that spanned two thousand years -
Let the torrent of steel sweep across the world, let the word Qin and the language of Qin become the global language, and let China two thousand years from now no longer have unequal treaties, no history of humiliation, and no longer have to be beaten for falling behind.
