Although the skeleton of a Titan was not as precious as the remains of the Dragon of Destruction which was one of the five Dragon Aspects, Lin Li could put the Titan skeleton to great use with his current abilities.
The Dragon of Destruction mastered the Laws of Darkness and Laws of Destruction, and there were also plenty of Dark Force and Destruction Force in its bones. Given Lin Li's current abilities, it would be almost impossible to fully utilize it without any wastage. He could probably only achieve such a feat when he became a Divine Smith. That was the reason that he had not touched the skeleton of the Dragon of Destruction after such a long time.
However, the skeletons of Titans were completely different. Since Lin Li was a Smithing Guru, he could use them to forge weapons, create strong magic arrays, or build indestructible castles. He could fully utilize it without any wastage.
