It was almost just over an hour.
Duncan's Mana Bar was completely exhausted.
He had to stop his cultivation because there was no Mana to drive the nanobots to enhance himself, which was a bit contrary to his understanding of cultivation, as strengthening through cultivation actually consumed Mana.
During this process.
The mechanical nanobots in his body seemed to undergo a slight split, but the overall quantity didn't increase much because when the nanobots were enhancing the lungs, some of them directly disintegrated. They integrated into the human cell level, somewhat like carbon fibers, or possibly an unknown structure of metal fibers.
"If this focuses on strengthening the muscles, then they will really turn into steel wires!"
"And worse, it would be steel wires!"
