Half a month later, when Cao Rui was on his deathbed, Sima Yi arrived at Luoyang. Cao Rui held onto Sima's hand and summoned Cao Fang and Cao Xun (another adopted son of Cao Rui) to his bedside. He pointed out Cao Fang and told the boy to hug Sima, as he would hug his father. Cao Rui then instated Cao Fang as crown prince and died on the same day.
