Although many of the higher-ups had quite a few reservations about Chen Yan's proposal, after weighing everything, they found that this seemed to be the only plan with the highest feasibility.
In the end, they all cast their votes in favor, albeit reluctantly, and passed the proposal.
From that point on, the Chen Family Domain was shrouded in an enormous and powerful network of formations, while every Chen family member received a fragment of the Blade Manual and was forced to study it.
To prevent outsiders from becoming suspicious and linking the Chen family's actions to the demon invasion, the Chen family higher-ups even gave the Blade Manual an alias.
They selected a word from the "berserk" aspect of the Tenfold Blade Technique and used "mad" as its marker, naming it Mad Blade.
They publicly claimed that it had been created by a Chen family elder who had remained in seclusion for years, and that it was a blade technique belonging to the Chen family itself.
Everything went exactly as Chen Yan had envisioned, except for the progress of the other Chen family members in learning Mad Blade.
