In order to complete their thesis, Qi Qi and Ai Ai, who are almost identical twins, have to travel through different times and spaces.
Each time and space has its specific research object. It may be a beggar wandering on the street, a high-ranking royal family, an extremely useless waste, or a darling with both intelligence and intelligence. No matter who is targeted by them, they will always die without a burial place.
Continuous updates, in other words, irregular updates, endless pitfalls, and something to fill your teeth after a meal.
