Who was the most loyal officer of the RTK era?
My main choices are Zhang Liao, Guan Yu, Zhang Fei and Shen Pei.
Zhang Liao for serving Wei for so long and helping shape the Wei dynasty and defend it. Guan Yu and Zhang Fei for being loyal to their brother above all else and Shen Pei for never even considering joining Cao Cao but dying facing his lord in the north.
Who are your top picks?
