Yang Xiao is considered an illegitimate child rather than the eldest legitimate son, which Chen Nang can justify. After all, Yang Xiao's current job is a bloodthirsty endeavor and secretive, entangled daily with a group of Evil Cultivators. If he were a legitimate son, he wouldn't be risked in such dangerous activities.
However, being an illegitimate child makes it acceptable. While the danger is indeed significant, it also allows for military merit accumulation in preparation for his future aspirations.
But as an illegitimate child, he is still cherished by the family. To prevent him from dying prematurely in his entrepreneurial ventures, he was equipped with ample top-grade magic artifacts for defense. Additionally, he likely has a master of at least Half-step Nether Realm level carefully guiding him, honing him into such a formidable figure.
