The Unsolved Puzzle of the Era

In 3000 AD, it tells the story of four time and space travelers equipped with top-notch technology - tactical expert Qin Lie, scholar Su Mo, mechanical genius Tang Tang, and quantum archaeologist Lin Qian with the power of "empathic retrospection" - as they embark on a cross-time and space adventure to explore historical mysteries. The four of them encountered a "time amber" trap disguised as mechanical mimicry in an extreme desert environment. During the fierce battle, Lin Qian was accidentally locked by a high-dimensional mechanical creature and received a top-secret encrypted code from the year 3000 with Qin Lie as the sender. After a thrilling escape from Lop Nur, Lin Qian read key clues from the ancient jade pendant projected by the mechanical body. As the layers of the mystery were peeled away, everyone discovered that this seemingly simple historical investigation was actually a huge and carefully arranged chess game. In order to solve the paradox of "why Qin Lie sent signals to the past in 3000 years" and to explore the ultimate secret behind "Pisces", the team locked the next destination at Shennongjia, and a more dangerous time and space mystery began.
