Silently gathering his Spiritual Power, Tang San slowly infused it into the Earth Shattering Hammer. Suddenly, he felt his Spiritual Power as if entering a hot spring, a warm sensation enveloping it, giving rise to a feeling that it was burning ever more intensely.
This is one of the Heavenly Fire Fine Iron's characteristics. It has an extremely strong burning effect on any object but, paradoxically, nourishes Spiritual Power and is also dominated by it.
The warm sensation slowly turned scalding, yet far from fierce. Tang San silently experienced the changes in his Spiritual Power, continuously maintaining its infusion.
The first spiritual fusion with Heavenly Fire Fine Iron required a long period, Tang San estimated at least seventy-two hours for completion. This was also why both the Monster Clan and Spirit Clan had not uncovered its mysteries.
