Davis knew that the breakthrough would take a week or more, but if he was interrupted during this time, his breakthrough might fail in the end as the soul essences that he was currently refining might be lost.
He knew that he had to absorb the soul essence quickly as it is refined, or the pure yet refined soul essence would disappear within a few seconds.

He had once figured that he could share these soul essences with someone else like his wives, but without Fallen Heaven's presence to support their soul, he doubted if they would be able to withstand the quick rise in one's quality of the soul essence that led to their breakthroughs in Soul Forging Cultivation.
He felt that it was just not possible for others to grow as he did in Soul Forging Cultivation.
