The incident on Dwarf Mountain was settled by a single blow of the Saint Empress' Demon-Killing Seal. The four races also didn't dare to continue with their attacks. The other races who had designs on Dwarf Mountain also did not dare to act anymore and retreated as well.
Of course, with Qiu Shan being killed by Jiang Yi and the Dwarf Race army being almost wiped out, there was no way Dwarf Mountain could still be secured. If the Dwarf Race decided to protect Dwarf Mountain to the death, their race would definitely be annihilated. A man's wealth was his own ruin by causing others' greed; a sacred mountain was too tempting for anyone. There would definitely be great races who would not be able to resist the temptation to takeover Dwarf Mountain.
