After a long conversation with 0542, Jiang Fei finally understood what had happened.
Apparently, Jiang Fei was not the first person to possess Braveheart's core controller. The mysterious ring had been used by many earthlings before Jiang Fei's time. However, back then, the state of technology was not very advanced on earth. Therefore, the Intelligent Assistance System was not able to help the ring's previous owners as much as it could help Jiang Fei now. In spite of that, the ring's past owners had still achieved quite a lot during the time they possessed it.
