Lin Huang returned to the Iron Fist Shelter after he was done with the Tyrant Bug King.
However, he did not hand over the mission items right away upon his return. Instead, after accepting the mission to kill the Horned Beetle on Death Sickle's missions forum, he rented a cultivation room and went into closed-door cultivation.
Once in the cultivation room, the first thing Lin Huang did was to give the Tyrant Bug King's bug beasts' spiritual energy to Fading Petals and Creation Clock.
Although the bug beasts that the Tyrant Bug King had conquered were less powerful than the Wine Ant Queen and the Spider Empress, he had many high-level Virtual Gods under him. He had dozens of Virtual God rank-8 and Virtual God rank-9 Bug Kings; some of them were even mythical-level. The total sum of spiritual energy was not that different from the other two missions.
