"They are called the Phantom Brigade," Zhong Yuan informed.
After receiving the reports, Amon called Zhong Yuan and the others to discuss the matter inside his command tent.
"They use invisible talismans before engaging the enemy and hide among regular troops," Zhong Yuan continued. "They march together with the regular troops and strike the enemy while the enemy is busy fighting the regular troops. The troops they march with have been trained to leave some spaces between them. This allows the invisible soldiers the space to move around. Of course, many within the brigade possess Mystic Stage cultivation levels, which makes them even more deadly. They can strike from above without anyone being aware of them."
"This method is not a surprise. We from the Royal Assassin Corps also use it," Gao Xingzi remarked.
"An individual using an invisible talisman might not be surprising, but what if I tell you the Phantom Brigade consists of a battalion of one thousand soldiers?"
