Xu Yang led A40 to the island to excavate weapons left by the Shura, which are better than the ones A40 is using now.
The Shura was notorious for killing people indifferently and had an interest in killing Samurai and collecting renowned katanas, only choosing the best among them, making three peerless weapons his personal blades.
Thanks to the advanced information technology of the present and Shura's own hints, Xu Yang was able to locate each of these three weapons.
"Flying Colors," a vermillion-colored glass katana that could destroy living beings. The flames infused in it could ignite an enemy from the inside. The Shura used it to kill people. It was snatched away by Westerners and is currently in the collection of the Great Britannia Museum in Lundinium.
