Chapter 449: Chapter 219: 4th Upgrade

Yan Fei stacked gold on Misty Island because he needed to use Universal Space to transport materials for the Drone Upgrade. However, he made a fatal oversight by not realizing that the smelted gold bricks were installed with position locators. Had it not been for the extremely amazing location of Misty Island, the locators in those gold bricks would have already relayed the position of the island. By then, not only would Yan Fei's drone upgrade be facing huge problems, but he himself would have been subjected to the US Forces' frenzied retaliation.
