There was not much need for me to eat food as I wasn't in a complete body, but my mortal tendencies won't allow for me to not eat anything as I have yet to get used to the corporeal body.
Chen Xiao had told me that he would arrange a test for when I would be breaking through to Body Refinement 3rd level. He said that he would send me somewhere to a different plane, but that I would still be here.
I'm guessing that he meant my conscience as I have yet to make it to a level to form an actual avatar body and send it there, he would provide that for me as long as I could support him.
After giving me this information he had wen't silent so I decided not to pry too much into it and just ask whenever I had broke through to the 3rd level.
I then proceeded to refine the Lower Void Essence in the surroundings, I would be able to refine the 1000 to be able to refine the Mid Tier 1 Void Essence. But after that I would then need to upgrade to 'Copper Stomach' then 'Iron Stomach', etc.
There were more levels of the technique but I shouldn't worry about them for now as I have yet to get close to Iron Stomach. After forming 'Stone Stomach' my body had been strengthened a little bit. All that I needed to do was to continually strengthen my body using the Void Essence.
So I got started on refining my body, and after what felt like a month my body had been strengthened by a considerable degree so then I would be able to refine more Void Essence as I didn't refine much when strengthening my body as I was using the Void Essence to temper my body.
In total I had refined about 350 molecules of Lower Tier 1 Void Essence. The only thing that was left to do was to refine 650 more to equal 1000 so that I could form the Copper stomach so that I would be able to refine the Mid Tier 1 Void Essence without spontaneous combustion occurring.
