Arslan and Eliza didn't wait for the others to react and kept the initiative.
"Steps Of Silence!" Arslan moved like a shadow inside his Darkness' Domain not giving his opponents to reorganize their strategy. He was aware that he couldn't keep the Darkness' Domain for long but he could use it for a longer time after breaking through the late stage.
Arslan defeated one disciple after another, conscious that speed was the only way to get rid of them all in the little time possible. Eliza supported him from behind when Arslan had a difficult time handling a few disciples. Their duo became the other disciples' nightmare.
John regained his confidence after witnessing what Arslan and Eliza were doing just by themselves and decided to lend them help. He wasn't specialized in fighting techniques by his awareness of their surroundings was second to none.
