After Long Bo's death, his soul lamp back in the sect was destroyed, thus alerting many of the other elders. Many people sighed at this unfortunate event, but few actually cared-- even the members of his own faction.
People like Fan Lei, the Great Elder that oversees the library, knew that this was a predicted outcome. Although he wished that his old friend would not do anything stupid to force the sect to do anything against him, unfortunately for him, his wish did not come true.
So, after taking a few moments to grieve the death of his old friend, he moved on with his life. In the cultivating world, death is a constant and eternal theme; death is nothing but one of the many natural cycles of the universe, of the Dao.
