Red Coral Island

Since the island is both remote and made of coral, where he is unlikely to be bothered by other humans, Han Li deems it a suitable place to grow Neon Grass. He sets up three formations - the Illusory Heavensifting Formation, the Fierce Heavenly Wind Formation and the Five Elements Reversal Formation - and uses the Neon Grass to lure in a Grade 5 Thousand Eyed Demon and several other demonic beasts, until he has collected enough demonic cores to support his Core Formation.
