What would you do if you had muzans powers in that time period. Assuming no yorichi

like muzan oh muzan. he can split into hundreds of blobs to escape but doesn't have back up clones of himself. he can make cacoons and tendrils yet stays the size of a small human instead making the main body harder the earth crust safe from attack. he gets hundreds of demons but only gives at most five short range weapons instead of bows and crossbows that most demon slayers can't defend. he can kill anyone instantly yet rather keep them divided so they can be conquered. he continually made demon when stoping for like 300 years would make demon superstition and demon slayer lunatics who would be burnt on the stake. he never thought of farming humans in the castle for stable food supply with enough space to keep a small city to sustain all upper and lower moons.

he does so much wrong simultaneously some how what would you do
