Four days had passed and the remaining eight black crystals in the inventory had been consumed by Gu Ding, who had completely absorbed the energy.
There were thirty-seven energy circulations built within Gu Ding's body and his Cell Index had increased from more than three thousand points to ten thousand points. However, it was strange that his Cell Index was stuck at this point and he could no longer enhance it any further. As for his gene level, it was stuck at Rank 5 and he could not make a breakthrough to Rank 6.
Neptune had explained this as "The seal on the gene locks being overly secure. This energy was not enough for Gu Ding to overcome his gene locks."
