Chen Guan arrived at the entrance of the Ji Family's Great Cave Heaven disguised as Zi Donglai, claiming to visit the Ji Family, though everyone in the Ji Family could naturally see through his intentions.
However, they pretended to be ignorant and did not expose Zi Donglai.
One reason is that the Ji Family and Zi Donglai have no conflicting interests, and secondly, the Ji Family is currently overwhelmed with troubles and has no energy to deal with these trivial matters.
Moreover, the Ji Family has interests in the Pengxuan Grotto Heaven. If they trouble Zi Donglai, their interests in both the Grotto Heaven and the Blessed Land might be affected.
There's even a possibility of being wildly retaliated against; they certainly don't want to use their interests to avenge others.
