Seeing this scene, Grandpa Shi Tian couldn't help but frown deeply.
It wasn't unheard of to concoct two batches of elixir medicines in a row, but that was usually only feasible with elixirs of a lower rank.
For Lin Jing, as a seventh-grade alchemist, to directly concoct two batches of seventh-grade elixir medicines in succession was not entirely unprecedented, but it was extremely rare.
If it weren't due to some kind of special circumstance that left no choice, a normal person wouldn't opt for this approach.
Concocting elixir medicines is already extremely taxing on the mind, especially so for higher-ranked elixirs.
An ordinary alchemist would be quite exhausted after concocting just one batch and would have no choice but to rest.
But this time, Lin Jing had just finished concocting one batch.
And the batch of Soul-Returning Pills he had just concocted appeared to be quite good, containing two supreme-grade elixir medicines.
