Dao Companion (Reuploaded)

At the tender age of 25, Klein reached the legendary status of Fifth Circle Mage, but his obsession with immortality drove him five years on a dubious elixir of immortality, unfortunately, to be transported into a completely different world. 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.
