Thunder Marsh Wilderness.
According to rumors, this wasteland is prone to lightning strikes, hence its name.
Within the wilderness, there exists a group of 'Thunder Beasts'. These wild beasts are naturally adept at controlling the power of lightning, and the elite among them are comparable to Immortal Cultivators who have reached the Returning to Emptiness stage. The king of the Thunder Beasts can release gold and silver twin-colored lightning, which even Cultivators at the Integration stage find hard to avoid.
Fortunately, for some unknown reason, this group of 'Thunder Beasts' disappeared ten thousand years ago, providing an opportunity for the human race to start developing plans for the Thunder Marsh Wilderness.
Even so, above the Thunder Marsh Wilderness, there still exists an untold number of precious and exotic creatures, concealing countless dangers.
The human race's previous attempts to reclaim the wilderness have all ended in failure.
