A new author, one female lead (Camearra)
The protagonist, Li Yu, suddenly transmigrates to the world of Ultraman Nexus. Just as he is about to become food for a Space Beast, he is taken away by the weakened Dark Zagi. It turns out that in the final battle, Dark Zagi was not destroyed by Ultraman Noa, but regained his sanity. However, the First Space Beast took advantage of Zagi and Noa trading beams to ambush Zagi, stealing part of his power and the Unknown Hand, and leaving him injured by Noa.
With Zagi wounded, the First Space Beast gains that stolen power and becomes stronger than Zagi. But it is also injured by Noa and flees. As Zagi is on the verge of disappearing, he sees the protagonist and entrusts him with all of Zagi's legacy. But an ordinary human cannot withstand Primordial Darkness, so Noa can only seal away most of the power.
Li Yu must therefore transmigrate to other worlds and absorb dark energy to strengthen himself,
become Primordial Darkness,
and surpass Primordial Darkness!
To be honest, this book is basically the same as another novel I read. Even the identity of the protagonist belongs to Zaki and Camila is the daughter of Gatanje.
