By ensuring that every Jiangshi required periodic maintenance from him, Han Yu had effectively created a continuous point of contact with every buyer. Each return would become an opportunity, a chance to observe, adjust, and most importantly, to implant deeper layers of control.
The offer to upgrade existing Jiangshi was another calculated move.
Han Yu had already confirmed through repeated experiments that he could introduce Eight Emotions energy into completed Jiangshi. The process was more delicate than working with a fresh corpse, but it was entirely possible.
Even in cases where the upgrade failed, the outcome remained in his favor. A failure could easily be disguised as degradation or instability, after which he could recommend a replacement from his own Ju Series for free.
From the perspective of the buyer, it would appear as a normal cycle of maintenance and replacement.
From Han Yu's perspective, it was infiltration.
