The problem with the hypothesis that Loki had an helper is that as long as Gold Body is fighting another divine being, he would never bring out his shoddy Cave Heaven to fight with it. Therefore, even if Gold Body had died, his Cave Heaven should be safe after his death.
There are only a few special ways to attack the Cave Heaven directly. This is why he never expected that Gold Body would be gone forever.
But now that he knows that Gold Body was gone forever, what he wants next is to know how Gold Body died and how his Cave Heaven was destroyed. Unfortunately for him, Loki is adamant about keeping the fight a secret.
Since Loki has decided to keep the fight a secret, any means to investigate it through the divine constellation will be blocked by Loki. He will have to spend so much of his lifespan that Loki gives up before he can learn the information he wants.
