Last enlightenment

'If there isn't enough energy in all those pure mana resources, then why shouldn't I cultivate using pure mana alone?' I thought. 

The goal for my current cultivation was to get strong enough to safely keep all the anti-mana scattered on the battlefield in my own system. And while I got considerably stronger just by absorbing the normal monster remains...

Without breaking through my current stage, there was no way I could take care of the small lake of liquified anti-mana all on my own!

'Well then,' I thought, taking a deep breath and closing my eyes to focus on the task. 'Let's crack this nut!'

First came starting the engine. A process that was near impossible to achieve without pure mana already in my system. 

Just like building a Dyson sphere for a civilization required so much energy, it was often said to build a Dyson sphere you needed a Dyson sphere, my engine had the same type of paradox.
