Noah used the first week of the trip back to the academy to rest, he had to stabilize his condition again.
Increasing one's strength so rapidly was quite dangerous.
The dantian was an organ after all, too much stress on it could ultimately lead to an injury.
The same went for the sea of consciousness, the mental sphere had to be enlarged gradually or there would be the risk of breaking it.
Noah sat on one couch inside the carriage escorting him back to the academy, he was calmly analyzing the condition of his body.
'My dantian has completely recovered, there is no danger in resuming my previous training rhythm. My accumulated stress also has disappeared, it seems that the constant battles that we underwent in the inheritance ground helped my mental sphere quite a bit.'
Overall, they had been away from the academy for four months while his actual time spent training his dantian and body was equal to six months in his accommodation.
