As soon as the Sword Sect sect finished preparations for the war elder Du decided that they would head towards the border rather than wait for the Western Sea Sect to start advancing first.
Elder Du hoped that Sword Sect would take advantage of the disciples' higher morale and anger to strike first and thus gain advantage in the war, and with Elder Du Sword Sect had an advantage until Western Sea Sect reinforcements arrived, so Elder Du gave a short speech to cheer on the members of the Sword Sect before this war.
"Our sect is now leaving to take part in a war, it was a war that our sect did not want and was provoked by our enemies, our sect even being one of the strongest of the divine plane never abused our power and always sought order and peace."
