The information about the success rate in becoming a Heavenly Law User hit Robin where it hurts
Leaving aside the fact that Planet Nihari has a population of tens of times greater than Planet Jura and it's only fair to think they have far more soldiers than him right now, the main key here is that Planet Nihari has hundreds of Emperors… Until this moment, he hasn't even found a way to deal with those at the Emperor Realm, yet his dream army is already crippled before it was even formed!
Even though Planet Nihari Emperors rely only on physical strength and cannot fly -As far as he knows- they are still unstoppable moving blocks of pure power!
Years passed while he was studying the situation, and he found only two solutions...
The first is to produce hundreds of thousands of Sages and provide them with all he can of divine equipment and talismans and prays that they are sufficient to bary the Emperors with numbers, and this does not seem available now after reading this report...
