Today, Langde seemed a bit anxious, different from yesterday. Lin Tian followed him to the laboratory, and as soon as they entered the underground passage, a strong scent of blood hit them.
However, Lin Tian could tell that this blood scent was not human blood but animal blood. As a zombie, Lin Tian was most sensitive to the smell of blood, especially human blood, because zombies relied on absorbing human essence to survive, though he was an exception.
When Lin Tian entered the laboratory, he saw bottles of red liquid lined up on the shelves, and the scent of blood was emanating from there.
"Elder Langde, what is this?" Seeing so much blood, Lin Tian was quite puzzled about Langde's intention.
"This is one of the raw materials for the potion. There are other herbs here as well." Langde gestured, walking over to a row of cabinets, and opened the door. Inside were bundles of herbs, with some in boxes.
