In an instant, on the transformed blood-colored long saber's blade, tiny blood-colored seal scripts were clearly engraved, appearing ancient and exuding a primitive aura.
These scripts were evidently the long-lost Celestial Demon Secret Patterns, representing the Demon Dao of the Outer Celestial Heaven, each naturally possessing polluting power, with each script being a source of pollution, even capable of corrupting the Heart Spirit.
