Owen Bertram estimated that he could now command about 500 people.
By using this Sharp Arrow Formation Art of War Treasure Book, he could command these 500 people as if they were Dao soldiers, extremely obedient under his command.
They could form the most powerful "Sharp Arrow Array" in the world!
It sounded impressive, but in the end... it was just an ordinary battle formation!
Owen Bertram shook his head, feeling that his artifact was somewhat perfunctory.
There was also another book called the "Honeycomb Fortress Construction Picture Record".
This was even more absurd. It was a way to construct a battle fortress with a beehive-like structure, not a magical instrument. It couldn't fly, just a blueprint for a castle building.
