[DROPPED!!!]

At the peak of his power, Klein could not abandon his obsession with immortality. He spent five years on a dubious elixir of immortality, unfortunately, to be transported into a completely different world filled with fantasy races like Elves, dwarves, giants, satyrs, orcs. 

Thankfully, the elixir of immortality wasn't a total flop, as it gave potential greater than the Heaven's Chosen with a slight caveat.

Klein will have to dabble in various paths of cultivation, orthodox and unorthodox, to reach his dream of immortality. But before all that, he needs to escape the wrath of the elves, for accidentally becoming the Dao Companion of their princess. Unfortunately, the task became a lot harder when he didn't even know their language.

Klein remained seated on his chair and watched the two elves giving each other the silent treatment.

Some time ago, the slightly older-looking elf woman with cropped silver hair had created a huge portal through which they had teleported all the people. When it was time to teleport him and Siona, she had brought them directly into an enclosed room.

He could tell her portal was formed with some higher form of the same Law of Space that he comprehended. Of course, his version still only enabled him to detect things in his surroundings.

Can she help me learn that? he wondered, his eyes darting towards her.

Finally, the impasse ended with Siona uttering some words. He was pretty sure she uttered the name Elanor while addressing the other high elf.

Elanor said something in return, her face devoid of any emotion.
