Besides that, the Crimson Sun Emperor had two other reasons he could not speak of.
One reason was that he had once killed a member of the Blazing Flame Clan Direct Lineage and obtained the Blazing Flame Clan's inheritance, which was how he had truly risen to power. Thus, the Crimson Sun Emperor himself had entanglements and grievances with the Blazing Flame Clan that could never be untangled.
If the Blazing Flame Clan truly rose again in the future, the first to be purged would inevitably be powers like his that had stolen from, and even hunted, members of the Blazing Flame Clan Direct Lineage!
This made the Crimson Sun Emperor determined to destroy everything related to the Blazing Flame Clan's resurgence.
This had been the reason for joining forces to suppress and kill the Blazing Flame Overlord, who had Self-Proven Taboo, in the previous era.
And now, the reason for completely exterminating the Radiant Day System, the strongest surviving feudal power of the Blazing Flame Clan, was the same!
The second reason was that although the Radiant Day System appeared to be fighting year after year, it was actually continuing to grow stronger.
It must be known that the Radiant Day System and the Ten Thousand Demons System were not merely capable of reaching the late stage of the Level 5 Star System,
Rather, these two old feudal powers from the era of the Blazing Flame Clan had deliberately limited their upper limit to the late stage.
After all, once they reached the peak of Level 5 Star, they would inevitably covet the Small Star Core, interfering with the Blazing Flame Clan's rule at the time!
Therefore, both the Ten Thousand Demons Emperor and the Radiant Day Emperor had once sworn blood oaths not to advance to the peak.
