Actually, ever since Thomas Turner had blocked the way here with his people, various powers had already discovered the situation. Only after inquiring did they realize that Thomas Turner's grandson had been murdered and had even lost a Sacred Fate Seed. This made it clear that the person who killed his grandson must also possess a Sacred Fate Seed.
Even one Sacred Fate Seed was enough to stir people's desire, let alone two.
While Thomas Turner was blocking the way here, more and more people hid in the periphery, also looking to see if there was an opportunity.
Thomas Turner knew there were people on the outskirts looking for an easy pick, but he didn't take them seriously at all.
In Thomas Turner's opinion, killing an Eight-Star individual was not a big issue.
