Angel Island has never been just a name.
Tan Jincheng has long been investigating Angel Island, not only him, but every country and force in the world, including China, is seriously investigating Angel Island as long as they know of its existence.
But in reality, the countries that can uncover anything significant are very few.
The country with the strongest intelligence capability is undoubtedly Country M, but China's intelligence capabilities are definitely not lacking.
Tan Jincheng began his investigation into Angel Island long ago, even before he truly met Gu Yi'an.
Despite years of investigation, the data China has on hand is still limited, not knowing the location of Angel Island, its specific structure, nor its true purpose.
