Spiritual Energy minerals are a good thing, accelerating the accumulation of Spiritual Energy, and allowing Angel Envoys to advance more quickly.
This is an exceedingly precious existence for all Contractors, but it does not include Su Han.
Of course, he could also use Spiritual Energy minerals, but compared to the power enhancement brought about by Fusion, Spiritual Energy minerals weren't so prominent – they were only an alternative, or even slightly inferior.
In terms of increasing his strength, Su Han had more options, but undoubtedly, Spiritual Energy minerals might be more suitable as Fusion materials.
After all, it was a new option, and it always seemed a bit promising.
He considered it for a while and decided to just do it and see what happens.
Although the yield of Spiritual Energy minerals isn't too much at the moment, it's relatively stable. Even if there's a shortage for a while, they will still be available later.
