After finalizing his deal with Isaac, Jacob sneakily returned to his house with the box full of distillation equipment
Now the question was where he was going to assemble them, and he still didn't forget about how he got spotted because of that smoke.
Although he was in a human settlement now and there wasn't any problem with the smoke, he wasn't supposed to be in his house right at this moment and if anyone found out, he was there it would be cumbersome.
Nevertheless, Jacob still decided to just assemble it in his backyard which wasn't in other's view and there was only the town wall a few tens of meters away from it and as long as no one sneaked in that place they won't be able to see the smoke in the night.
It took him half an hour to assemble the distillation equipment, and it wasn't too big or small; it was just right for his need.
Thereupon, he put the dry woods he collected the other day in the furnace and then took out the metal box with arrow tail jaguar heart and blood in it.
He chose to first absorbed the uncommon animal heart essence because he was afraid if he first absorbed the wolf king's heart essence, which was a rare beast, he would get fewer benefits.
He still didn't know if it would affect his progress to absorb strong species heart essence or not, and how much he needed to reach 100%. But according to Immortika, he didn't need to worry about not getting the effect of any new species' heart essence.
As long as he absorbed the heart essence of new species, he'll indefinitely progress and the only difference was in the tires of species. The higher the tire of a species was, the faster he'll progress.
After closing the lid and making sure that everything was in order, enter the house again and waited like before, and he was also keeping an eye on any intruder or some curious prick.
However, in eight hours, nothing out of ordinary happened and the distillation process went smoothly without a hitch.
Sun was also rising, so he covered the equipment with an old cloth and returned inside with an iron beaker filled with crystalline heart essence.
He took out the same metal syringe he used for his first injection. He was lucky to keep it inside his pendant, or it would be another problem to find another one like this in this place.
Jacob was in the basement right now where Pig Head was hiding, and he also chose this place because if anyone intruded, Pig Head could handle them as long as they weren't above B Rank Mercenary.
After giving the order to Pig Head, he sat bare chest and took a deep breath before he pierced that syringe in his heart.
Not only he didn't feel any excessive pain like before but as the arrow tail jaguar's heart essence quickly get absorbed in his heart and a cold sensation ran all over his veins.
He didn't lose his consciousness and remain static while he felt that cold sensation all over his body and his wildly beating heart.
On the inner wall of Jacob's mutated heart, the dark mark stirred, which had appeared after the carcass of Bloodstorming Bug merged with his heart.
The dark mark was becoming more and more apparent and talking a shape, but it was still too vague.
This was the Immortal Mark, which was now becoming the Cursed Mark, according to the second level of the cursed heart emergence.
This process continued for two hours before Jacob felt that sensation vanish, and he knew the entire heart essence was absorbed. But he could tell the change brought by this heart essence wasn't as apparent as the last time.
"Is this the difference between rare and uncommon species' heart essence? Although my strength has increased, it's subtle." Jacob mumbled.
Nevertheless, Jacob stood up from his spot and headed toward his small kitchen, since he felt hungry after this injection. He had already bought supplies, which would last him a few days.
But they weren't nutritious since the meat was from common animals, but they taste alright.
Afterward, Jacob again started to sharpen his fighting styles and get used to his increased strength until the night was upon him.
He bathed before starting the distillation process again.
Just like yesterday, he waited all night for the heart essence and then injected it into the basement.
However, this time, Jacob felt slightly pained when the dark wolf king's heart essence entered his body. But it wasn't unbearable that he couldn't handle.
Furthermore, he suddenly felt a large amount of sweat releasing from his pores and his hair grew at a fast pace like before.
This time it took him ten hours for this absorption before his eyes amber eyes opened with a ghastly glint present deep within them.
'This wolf king was stronger than Decker and I could feel my body reached some kind of wall,' Jacob mused, and the very next moment he thought, "Cursed Immortality!"
He quickly looked at the progress of the second level, and he was astonished.
_______
…
-Second Level: Turn Immortal Mark into Cursed Mark
-Completion: 9.99%
…
_______
"Only 0.1% away from the 10%. Afterward, I would have to again eat like a lunatic to match my body with my heart. Well, it's not like I'm complaining." Jacob's lips curled upward.
Although it was only his guess, but he presumed if he hit that pillar with his full strength, it would show 1500 KG punching force. But he was still far away from matching an A Rank Mercenary.
Nevertheless, he knew as long as he continued to absorb the heart essence, A rank wasn't far, and he looked forward to it.
At this moment, the scripture's writing changed and Jacob knew who it was, and he frowned.
"Your luck is not bad. It seemed you might awake an ability at the 100% of the second level!"
