Inherit the Science and Technology Library at the Beginning, and Civilization Will Go Back Three Hundred Years.

Huo Ran, materials researcher at Longguo Equipment Research Institute. He accidentally received the interstellar information flow and obtained all the technology of Nak civilization. Before his death, the Nexians warned Huo Ran that large-scale hot war among humans would cause disaster. At this time, Dongyang wanted to purchase a batch of artificial rain bombs, and Huo Ran decided to try the effect of Nak technology. As a result, Japan almost returned to the Stone Age overnight. Under Huo Ran's agitation, the war capabilities of various countries have seriously declined. Dongyang: "Restart the Maoyan Project and start human-human radar." Great Britain: "Wooden sailing ships return to their glory days." Yingjiang: "Urgently form a flying pigeon messenger brigade." The surrounding jackals: "Oh, Dragon Kingdom, why didn't you retreat?" Huo Ran: "If one family is the only one, we can't fight. No problem!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
