陈登 / Chen Deng

Hanji 981 adds Chen Deng’s first persuasion scene around 刘备 and 徐州. When Liu Bei suggests 袁术 instead, Chen Deng argues that Yuan Shu’s arrogance and luxury make him unfit to settle the realm, and he offers Liu Bei a local support package of troops, military room, and the chance either to serve the court or hold territory.

Hanji 982 backfills Chen Deng before the later 陈珪 family-survival branch. The episode presents him as a top Xuzhou gentry actor who supports 刘备 because Liu Bei can carry reputation and Han-clan legitimacy without immediately subordinating 徐州 to 袁术’s 淮南 group. This makes Chen Deng a central source case for 地方豪强代理人选择.

陈登 / Chen Deng enters the wiki through the Hanji 1016-1018 late-Han branch as the official who can move between 吕布 and 曹操 without being trapped by either side’s expectations. Hanji 1016 supplies the precondition: 袁术 uses Chen Deng as leverage over 陈珪, but Chen Gui still refuses Yuan Shu and then uses the broken Yuan Shu-Lü Bu marriage path to open a route for Chen Deng toward Cao Cao’s court.

Hanji 1017 has Chen Deng meet Cao Cao in 197 CE, describe Lü Bu as brave but unreliable, and receive appointment as administrator of 广陵.

That episode makes Chen Deng’s value operational. Cao Cao asks him to handle eastern affairs and secretly contact Lü Bu’s people, while Chen Deng turns Guangling into a local base by training soldiers, storing grain, and recruiting Jiang-Huai figures. The source later says Chen Deng defects first during Cao Cao’s 198 CE attack on Lü Bu at 下邳, completing the family’s turn from Lü Bu’s orbit to Cao Cao’s.

Hanji 1018 continues the same channel. The episode says Cao Cao values Chen Deng, promotes his father 陈珪, and appoints Chen Deng to Guangling, while declining to give Lü Bu the 徐州 governor title Lü Bu wanted.

Chen Deng’s central move is interpretive. When Lü Bu believes Chen Deng and Chen Gui have benefited at his expense, Chen Deng reports Cao Cao’s “raise a tiger” judgment in a form that turns suspicion into a bearable compliment. The episode uses this scene to create 饥附饱扬: Chen Deng understands Lü Bu’s vanity, Cao Cao’s caution, and the interest structure behind unstable attachment.

The page remains source-scoped. The Hanji 1017 source gives a broader family-survival and Guangling base-building frame, while the Hanji 1018 title points toward Chen Deng’s wider reputation among Cao Cao, Sun Ce, and Liu Bei; the provided texts mainly develop the Cao Cao/Lü Bu branch.

Hanji 1026 closes the campaign payoff. The episode says Chen Deng earns the Fubo general title for service in the campaign against Lü Bu, confirming that his earlier intelligence and eastern-affairs channel become visible military-political credit after 下邳.
