The reason was simple.
Because they could not absorb them.
Some gentler heavenly treasures were manageable; at worst, they would not be fully absorbed, resulting only in waste.
But some were violent. If swallowed all at once, their energy could exceed what the body could withstand, causing serious problems.
This characteristic was clearly a headache for major powers, especially when it came to nurturing their younger generation.
Their warehouses were filled with treasures, yet they could not use them!
To avoid wasting these treasures and to give their younger generation a head start, the major powers had spent countless millennia racking their brains over this problem.
With the efforts of innumerable great figures, they had indeed developed quite a few methods.
Among them, the most universally applicable was absorption in batches.
It was not that they did not absorb them, but that they absorbed them slowly—gradually, rhythmically—allowing a small portion of the medicinal effects to be absorbed first, then finding ways to have that small portion drive the absorption of the larger portion. What was absorbed first would facilitate what came later, ultimately achieving as complete an absorption as possible.
It sounded abstract, but in truth, it was nothing more than taking something potent first, then either balancing it with other gentler medicines or assisting it with secret techniques, allowing the medicinal effects that had already reached their limit to be gradually absorbed in batches.
In Ye Luochen's judgment, what had happened to him was extremely similar.
The enormous amount of life energy that had previously poured from the Spirit-Devouring Carving Knife into his body had far exceeded what his body could endure.
The reason he had not been burst apart by that energy was likely because it was gentle and possessed the life attribute.
But that did not prevent
