Siheyuan: The Legend of the Old Sixth in the 1960S

Li Jianxun unexpectedly transmigrates to the 1950s and 60s, and from the start gets a double surprise that would make anyone envious. On one hand, he becomes the heir to a prominent revolutionary family, shouldering a unique mission and honor. On the other, he gets a miraculous, yet somewhat exasperating Shameless Old Six System, which is actually the strongest sign-in System. But this System has a special activation requirement: it can only be activated in a courtyard teeming with vermin and tangled relationships.
