Traveling Through the World, Who Else Would Save the World?

[Quick travel + four worlds + koi female protagonist + high IQ male protagonist + dragon and rabbit pet] A disaster unique to Jieyuan came quietly. The boundary stone that controls the balance of the boundary source was split into four parts by the impact from the sky. As time goes by, problems and contradictions begin to arise in each parallel universe. Four of the universes entered by the Boundary Stone fragments are in particular trouble, so two Boundary Origin travelers were chosen to travel through the parallel universes to find the Boundary Stone and restore peace. Male protagonist: Li Hao has a super high IQ of 250+ and is good at analyzing and solving problems, but he is lacking in interpersonal communication and emotional processing. Heroine: Jinse is a lucky koi, the chosen one. During their journey, Li Hao and Jin Se will travel through multiple parallel universes together and face various challenges and dangers. They will encounter a fantasy world of immortality, a world destroyed by apocalyptic disasters, a world with highly advanced technology, and a world full of magic and mystery. Each new world has its own unique culture and environment. Li Hao and Jinse must quickly adapt and find the boundary stone to restore peace to the universe. They can also return to the land of Blue Star, cook tea by the stove, and watch the flowers bloom and fall in front of the court. "The world is stable, and there are people carrying the burden forward!"
