Deng Ai is best known for his pivotal role in the Wei conquest of its rival state, Shu, in late 263.

Deng Ai was later promoted to the rank of an Agricultural Officer of Merit.
Sima Yi felt that Deng Ai was an extraordinary person so he recruited him and promoted him to the position of a Gentleman of Writing.
Deng Ai was sent to survey the lands from the east of Chen and Xiang commanderies to Shouchun, and assess their suitability for agriculture.
Deng Ai saw that the lands were fertile but lacked moisture, so they were not fully utilised.
Deng Ai suggested digging irrigation channels to irrigate the land, and open up new canals for transporting goods by water.
Deng Ai wrote a proposal, the Ji He Lun, to explain his ideas:.

Deng Ai pursued the fleeing Wen Qin to Qiutou, but Wen Qin still managed to escape and defect to Wei's rival state, Wu.
The Wei general Zhuge Dan ordered Deng Ai to resist the enemy at Feiyang, but Deng saw that if he was stationed in Feiyang he would be in a disadvantageous position, so he relocated his troops to a neighbouring village.

However, Deng Ai held a different opinion and he said:.

Deng Ai forbid his soldiers from plundering and pillaging the city, and ordered that daily activities in the city resume as per normal.

Deng Ai died before Deng Lang while his two sons perished in the Xiangyang fire.
Deng Ai achieved many successes, but failed to protect himself from hidden pitfalls and dangers, which resulted in his eventual downfall.
Deng Ai mentioned that Deng Ai had been deeply misunderstood because of his boorish and uncouth behaviour, which made him likely to offend people easily.
When Emperor Wu asked about Deng Ai, Fan Zhen became very emotional and he recalled that Deng Ai was a very loyal subject of Wei.
