The night was getting darker… Because of the death of his son, within a few days, hundreds of strands of King Lu’s hair had turned white. He could no longer sleep at night.
He had met Master Hu and the eighth king (a.k.a Rong Che). After some inquiries, he learned that there were conflicts that happened in the house of the General with the young lady, Gu Xijiu. He had suspected that Rong Yan was the culprit that killed his son but he lacked the evidence to prove it and was not confident of his guess.
Furthermore, Rong Yan was the emperor's favorite. Even if he committed the murder, there was nothing King Lu could do about it.
Despite having all the martial achievements and authority, he was still the brother of the current emperor. That year when he helped his brother to secure the throne, he was bestowed the title of "Bing Jian Wang" (a title which enjoyed almost the same authority as the emperor) and became extremely powerful and fearsome.
