There were two missions that Ethan wanted to complete as soon as possible.
They are:
[1) Helping Shadow Bee break through to the Golden Core Realm]
[2) Reviving the Green Lotus Tribe]
Both of these missions required Ethan to enter the Secret Enclaves that used to belong to the Primal Fang Tribe and the Green Lotus Tribe.
Currently, these two Secret Enclaves were being guarded by the powerful cultivators of the three Hermit Tribes, and thus, the two missions required Ethan to fight the Hermit Tribes.
As the strongest Hermit Tribe, the Bloodclaw Tribe had stationed the strongest cultivators along with the strongest cultivators of the other two Hermit Tribes.
Initially, after returning from the Realm of Life and Death, Ethan wanted to complete those two missions; however, after learning that the Bloodclaw Tribe was planning the second round of attacks on the Lin Family, Ethan changed his plans.
