"Sun Moon Radiance."
That was the name of the Soul Tool Lu Fa wore, and it was also one of the reasons Ao Hongchen had dared to let Lu Fa leave.
Sun Moon Radiance was Ao Hongchen's proudest creation. Ever since becoming a Limit Douluo, Ao Hongchen had been able to feel the restrictions the world imposed upon Limit Douluos more and more clearly.
He also felt that he was too old and that his potential had been exhausted. On the path of a Spirit Master, he had practically entered a state of half-giving up. After all, he felt it would likely be difficult for him to achieve another breakthrough in this lifetime, so he shifted the direction of his research elsewhere.
Soul Guidance Technology research, the manufacture of Black-Grade Mechas, and nurturing the younger generation—those were what Ao Hongchen now considered the most meaningful pursuits.
When a Spirit Master felt that they had reached a bottleneck and could no longer break through no matter what they did, they would turn to researching other fields to enhance their overall strength. However, the Spirit Masters who did this were generally those with mediocre talent.
Ao Hongchen himself was already one of the peak powerhouses of the current era. Whether it was Spiritual Power or Spirit Master cultivation, he stood among the very best. When he wanted to study other fields, it naturally came far more easily to him than to others.
Not to mention that the Hongchen Family had originally risen to prominence through researching Soul Tools.
This defensive Soul Tool, "Sun Moon Radiance," was actually a Level 10 defensive Soul Tool. It had both manual and automatic activation modes.
Considering Lu Fa's insufficient strength, when Ao Hongchen gave Sun Moon Radiance to him, he had already filled it with energy.
