Proposition (2)

When they arrived, they found that the True Soul Realm Experts of the True Spirit Sect, Thunder Sect, and Assassins Association were all here.

It seemed like their assumption was correct and they were planning on making a move against them.

So it was a good thing that they had brought their own True Soul Realm Experts.

It was 3 against 9, it was impossible that the other side would be able to do anything. But they should have expected this after they had sent their invitations, so what did they have up their sleeves?

Were they expecting them to doubt each other and pick factions off to bring over to their own side?

If they were, then it would be futile.

Perhaps they would have doubted each other if they hadn't talked to each other before, but these nine factions had something that connected them. They were all brought to the same side because of Lin Fan and it would be hard for them to convince them to betray this side.
