Hiick!
Tears streamed uncontrollably out of Hazen's eyes as his body trembled from grief. Everything he loved and wished to protect was no more.
Their opinion was that they were holding him back from excellence.
Until now, Hazen had the capability to protect the world despite everything. So, things were fine. But the moment a force struck that was beyond his capability, they realised their happy times ended.
If they remained behind any longer, Hazen would simply die alongside them. Therefore, they committed a collective suicide to shed Hazen of all the chains that held him back and kept him rooted to the Cultivation World.
This was just their opinion.
Hazen hated it. He just wished to be with them, until their last moments.
