Zhengjo Temple is an abandoned temple at the foothills of the mountains east of Minister Cho's Estate. There is a section of the temple that connects to Minister Cho's Estate explorable area, but it is caved-in and inaccessible. The only current inhabitants of the temple are Mantids, including the boss Yunlai Deathkeeper. Many of the Mantids will cause additional Mantids to spawn when attacked. The Necromancer quest Little Creatures takes you into the temple to kill the Queen Mantid.
