It took close to a decade for Lind to recover physically. His body recovery was remarkable even by Eternal Realm standards. Normally, injury from a fellow cultivator required extensive meditation and expulsion of alien energies so it was not unusual for centuries to pass missing limbs or in some way incapacitated.
Still, the dantian and energies were at full command in those instances. It was simply a matter of time and patience. Hiding away in their hold also helped keep them in peace.
What Lind had done, on the other hand, was far more complicated. It was his very foundation that had been pushed to the limit and wrecked his body in the process. Any normal healing or meditation was thrown out.
In fact, trying to use his cultivation at all would be a sure path to crippling.
Thus, after his body recovered, Lind went into seclusion to recover as quickly as he could. His recovery ability did extend to his meridians but his dantian was another matter entirely.
