As for when Xiao Tianyang had finished formulating it... he came up with the recipe while using the toilet.
After returning, he spent a total of three minutes producing the finished product.
It might not even have taken six minutes to turn all the Scarlet Fruit into the potions inside the crate.
Xiao Tianyang had originally intended to prepare [Life Essence] using the same method.
However, judging from the way Xiao Tianyang took out the [Life Essence], he clearly had not done so.
The reason was not that he was reluctant to use it, but that he believed [Life Essence] had greater development potential.
Its description indicated that plant-type beasts carried varying amounts of [Life Essence].
The only difference was likely the concentration.
Moreover, the fact that it could only be traded and not forcibly taken also indirectly revealed an unspoken rule.
That was, once someone attempted to seize it by force, food-type beasts would most likely actively destroy the [Life Essence] within their bodies.
Simply put, trying to take it was impossible. They would rather die than give it to you.
Besides, setting combat strength aside, the Heart Plant's vitality should have been at the Leader-level.
Therefore, the [Life Essence] it had offered was extremely valuable.
And the Lava Mountain Boar's terrifying vitality earlier was most likely inseparable from the Heart Plant as well.
Xiao Tianyang's knowledge of alchemy came from the system, not from years of dedicated study.
He could formulate potions from Scarlet Fruit because the material was not of a high grade and its internal structure was not complicated.
But [Life Essence] was different.
At least until he reached a definite conclusion, Xiao Tianyang would not choose to tamper with [Life Essence].
If he remembered correctly, there should have been an Alchemy Master on Douluo Continent
