Understanding what the lithium crystal before him truly was, Chen Xin lost interest in it.
Chen Xin was interested in genuine energy crystals, but when it came to matter-antimatter reactor catalysts, he had no desire to study them.
Not only does it require a vast amount of resources to potentially create a matter-antimatter reactor, but even if Chen Xin managed to build one, it wouldn't be very practical.
This is not to say that the technology was poor, but rather, for Flame Country at present, this technology was akin to a dragon-slaying skill, entirely unnecessary.
Firstly, a matter-antimatter reactor releases the complete internal energy contained within matter by annihilating both matter and antimatter.
