Following this, after a period of observation and experimentation, Fang Xi roughly understood the situation.
The Demon Tree could absorb flesh and blood, transforming it into the purest life essence to nourish its master!
And life essence was the key to many "longevity elixirs"!
"So... does this mean... every time I cultivate, it's equivalent to consuming a longevity pill? Could it be that the lifespan I lose each day might be directly replenished?"
"In that case, wouldn't I be able to live forever? No, wait, there's a crucial prerequisite missing, a large amount of vitality!"
According to Fang Xi's observation and judgment, the life essence the Demon Tree nourished daily could roughly equate to half a day of lifespan.
In other words, he could live one day as if he were living two days like an ordinary person!
His lifespan had directly doubled!
If he allowed the Demon Tree to absorb vitality without restraint, it might even be possible to achieve 'immortality'!
Of course, in reality, this was highly unlikely because the flesh and blood produced by the Demon Tree was limited. If he expanded the Demon Tree recklessly, even sacrificing the entire Peach Blossom Island wouldn't be enough.
