The golden sun came with an imposing manner, but it crumbled at the slightest touch. After it collided with the black sphere, the golden sphere shattered, leaving a fragmented Cave Heaven behind.
As Loki collected and devoured the pieces of the fragmented Cave Heaven, he frowned and thought, 'What a troublesome fellow."
In the past, Golden Sun would have resisted and fought back for a slim chance of survival. This usually gave Loki the opportunity to mark him and seal him after death.
But this time, Golden Sun didn't bother fighting him at all. As soon as Golden Sun sensed the presence of a Dao Lord, he chose to commit suicide and detonate.
Golden Sun didn't expect to kill the Dao Lord like this. He only hoped that his attack would create some Entropy to trouble the enemy while preventing them from gaining a Cosmic Dao.
As it is, it would seem that Golden Sun achieved his goal because Loki was annoyed. Two other people were annoyed by the turn of events, both of them Dao Lords.
