[Historical Time Travel x Strategy Technology Flow x Dynasty Hegemony]
When a doctor of science and engineering travels through time and becomes Liu Bei's grassroots adviser, science is the primary productive force!
The soul of Cao Yan, a modern military expert, traveled to the late Han Dynasty and became an unknown aide under Liu Bei.
Facing Cao Cao's million-strong army and Sun Quan's Jiangdong foundation, he held "Nine Chapters of Arithmetic" in his left hand and the gunpowder formula in his right hand, using scientific dimensionality reduction to attack:
Battle of Chibi? Calculate fluid mechanics first, then release the hot air balloon fire attack!
Zhuge Liannu? Upgraded to a three-bow crossbow with a range of thousands of meters!
Plague siege? Alcohol disinfection + isolation method, backhand to throw sick rats into Cao Jun!
What's even more amazing is——
Da Qiao became his intelligence queen and used the Zhuang brocade code to instigate rebellion against Soochow;
Huang Yueying became the chief engineer, and the steam engine was directly installed on the warship;
It was only when Guo Jia was dying that he discovered: This counselor actually knew about radioactive ores? !
When Liu Bei looked at his subordinates:
Gunpowder troops, biogas lighting, cowpox vaccine, movable type printing…
I couldn't help but sigh: "Sir, is this really the technology that the Eastern Han Dynasty should have?"
Cao Yan smiled and said nothing, and the telescope was pointed overseas: "Lord, our goal is-the sea of stars!"
