The Otherworldly Arrow Immortal

[Mortal cultivation + no System + another world + cultivation with bows and arrows]

Wu Huan accidentally activated an ancient teleportation array and was transported to a world of cultivation. By a stroke of luck, he obtained a portable space with a spiritual field and began his path to immortality.

They’re all cultivators, but while others cultivate the sword, he cultivates the bow. Others fly on swords, but he rides arrows. Other people’s spirit pets are magical beasts, while his are man-eating grass and man-eating vines.
