The Dragon Heart Core is indeed not easy to handle.
So far, Chen Fei has witnessed the fall of three Metallic Dragons, but he has obtained only one Dragon Heart Core, and indeed, there isn't a second one to use.
Instead of being used as a one-time consumable like an Element Annihilation Bomb, Dragon Heart Cores, especially those from Metallic Dragons, are better suited for places that can produce sustained benefits.
Chen Fei was quite bold and wanted to go all in, but Mino Heaton, the head of the Element Annihilation Weapon R&D Team, was a sensible person and did not accompany him.
You've got to be kidding, using the "planetary-level compute node" is incredibly satisfying, and the computational ability is almost endless. Regardless of the complexity of the calculations, answers can be derived in an extremely short time, enough to make other research institutions outside jealous.
