Saine's expression did not change upon hearing this. No matter what he had seized in this battle, it had nothing to do with the Heavenly Wing Demon Lord in essence.
What did draw a little more of Saine's attention was the Heavenly Wing Demon Lord's mention that this Level-11 Rule Crystal Nucleus had come from the Qihuang Castle Civilization and was the life core star of a Castle-type Gear Being.
Naturally, Saine was not considering returning this crystal nucleus to the Qihuang Castle Civilization afterward.
He was not some great philanthropist who did good deeds without asking for anything in return.
Saine had always acted with his own interests and those of the Mechanical Civilization as his core priority.
What truly concerned him was how exceptionally compatible the attributes of this Level-11 Rule Crystal Nucleus were with the energy circulation and rule fusion of the Mechanical Civilization Beings under his command. If refined and modified, it would surely become a precious treasure capable of raising the Mechanical Civilization's combat strength.
At the same time, Saine had more or less decided on the crystal nucleus's future use.
It could either be used to forge a top-tier war weapon or assist a core powerhouse under his command in breaking through their realm. Either way, it would maximize its value.

At the sight, Saine could not help casting another look
