Those Years When I Was a Bug in the Three Kingdoms

"If history is a program, then Guan Lin is the loophole." A modern engineer accidentally traveled through the Three Kingdoms and became the son of Guan Yu. He originally wanted to live a stable life, but he discovered that he had a "mark of another world" hidden in his body that could subvert time and space. Sima Yi's sorcery, Zhuge Liang's black technology, Sun Shangxiang's mysterious jade pendant... When the shadow of the "Sky Snake Clan" enveloped China, Guan Lin finally understood—— He is not here to change history, but to prevent higher civilization from completely resetting mankind.
