Teyan is the daughter of scientist Guangli. For 16 years, she grew up safely and healthily, but one day the Special Scientific Research Society began to pursue the whereabouts of suspected alien metal 16 years ago, which led to the story behind Teyan. Teyan's whole life took a huge turn, and she and her friends embarked on an adventure into the future. The secret began in 1999 AD, when an earth-shattering tsunami broke out in the Bermuda Triangle. A silver metal ball with a special material was discovered that year, and then it disappeared mysteriously. But that's just the tip of the iceberg.
