Han Yu looked at his daughter-in-law with a sense of helplessness and fear. Thankfully, the daughter-in-law knew restraint and only used the simplest and most superficial techniques. Otherwise, if anyone noticed and guessed something, Luban's secret skills could drive certain people to madness, stopping at nothing to acquire them.
It was also his insufficient capability to blame. Such secret techniques in their hands could only be used in stealth, not daring to be revealed. However, in those aristocratic families, it was nothing more than a display of power. Han Yu made up his mind to focus on developing their influence, for if even the trivial things revealed by his daughter-in-law caught attention, it would sooner or later invite trouble.
