Seeking the Dao Across the Boundless Sea of Worlds

Xun Dao unexpectedly obtained a System, along with a free chance to turn any book he chose into a cultivation manual.

So he looked at the copy of A Record of a Mortal's Journey to Immortality in his hands, his eyes full of anticipation.

System: "Wait! Host, I hope you'll think this through!"

He asked suspiciously, "Is there something wrong with this book?"

System: "...In any case, please consider this carefully, Host!"

So he turned to the bookshelf behind him, packed with twenty-four thousand volumes of the Chinese Taoist Canon, and asked, "Would one of these work?"

System: "...In theory, yes. Wait! Don't..."

From then on, Xun Dao could go roam the Boundless Realm Sea...
