The four Dao Treading realm Gu Legion members were at a loss seeing the appearance of a new moon above them. They knew that it wasn't a realm moon and was merely a formation array construct, but the feeling of danger they were getting from it was no less threating than the old man they had been battling since the start.
Even if they had been taunting and humiliating the old man since the start, they also knew that they were unable to kill him outright. If it were not for the fact that the old man was trying to contain them here and preventing them from causing damage to places where disciples of the sect might be hiding, he would have probably managed to kill at least one of them.
They had not forgotten the warning of their lord before.
