Jacob returned to his house and directly entered the basement to start the injection procedure.
This time, when he took the injection, his expression suddenly changed when that heart essence started to course through his veins.
This time he felt a sharp pain in his blood vessels and his heart seemed to be expanding in his chest and then reducing.
Suddenly, he heard a cracking sound that was coming out of his rib cage, and he caught up blood and groan in pain.
'Just what is happening!' He was in extreme pain, but he could still bear it.
But he could also feel those bones were mending slowly, as the pain was also decreasing. He wasn't in impending danger.
The dark mark in his heart was also becoming more and more visible with every heartbeat.
Thereupon, Jacob noticed dark blood coming out of his chest pours before it spread all over his body, even his eyes were bleeding in dark blood. But this time he didn't feel any pain, but as that blood was gushing out, he felt lighter and lighter.
This process only lasted for five minutes and so was the essence absorption process, since it was only from an uncommon species.
Furthermore, Jacob could feel the change in his heart rhythm, and it was almost soundless, and his body had become weightless. He felt it was someone else's body.
As he tried to stand up, his palms left a deep crack on the stony floor, but he could also feel the pain in his hand, he exclaimed, "It seemed I got more power than my body could handle and if I used it carelessly, I might get hurt. I have to start eating soon. I could feel that light hunger again…"
Jacob noticed the process only last for over fifteen minutes, and he mused it was because the more heart essence he absorbed, the faster the process would get.
He straight headed toward the bath before he cleaned himself, and he noticed he had become slightly burly from his ripped self and slightly taller.
After cleaning himself up, he took the advantage of the nighttime and started to turn more heart and blood into heart essence.
He wasn't planning on leaving until he absorbed all the heart essence, and he still had two days until his swords got ready.
Afterward, he was planning to look for that Tiger Bull on the run.
He was extremely confident in subduing it now with his current strength, and it was also the only piece of nutrition that can help him convert his body in one fell swoop, not to forget about its heart essence.
This time after making an injection, Jacob didn't wait or go into the basement and directly absorbed it, and just as he suspected, the heart essence of this uncommon crimson strip hyena got absorbed in five minutes, and he didn't feel any change at all.
'Although, I'm raising the percentage. But at this rate, I might need hundreds of uncommon species to complete this process…' Jacob mused as he put another heart and blood into the boiler.
'Nah, I'm too impatient, like the old days. I should calm myself down and think with a tranquil mind.' Jacob smile and returned to this resting position.
However, after he just absorbed the third uncommon heart essence and was about to put the last one on the boiler, he heard a sharp knock on his door for the first time he came to live in this house.
'It seemed news of my return spread quite quickly. Only those bigwigs around here will try to approach me, though. It might be cumbersome to offend them for no reason. Let's see who you are.'
Jacob hid the distillation equipment and headed toward the door. He wasn't afraid of anyone in this town or in this kingdom as a matter-of-factly, right now. So, he didn't have to hide his face here anymore.
'This heartbeat rhythm is quite peculiar, calm, and sturdy. At least a C Rank. The other is slightly fast while the third one is seemed to be in high gear, probably, agitate.' Jacob's hearing has become extremely precise after this small breakthrough, and he started to notice unique heart rhythms.
This could be a terrifying ability if he could refine it to a top level. But he wasn't even close yet.
Just as the door opened,
An old man and a youth appeared in his view.
Surprisingly, they were Austin and Kai!
Behind them was the butler of Taran's house, Harland, with a somewhat pale expression on his face as he looked at Jacob with somewhat apologetic, yet uneasy, eyes.
'What's the deal with him?' Jacob looked at the refine old man in butler clothes and wondered.
But he merely glanced at him as he looked at the old man in a blue suit.
He impassively said, "What do you want?"
Harland wanted to warn Jacob about Austin, but he knew better, so he remained silent since he knew Austin and Kai had followed him for some other reason. If he messed it up, it might inflict the house, Taran, so he could only watch helplessly.
Who would've thought this old knight would be interested in meeting with Jacob, the new C rank mercenary of rain town, and followed Harland here when he was about to come with a meeting gift from the Town Lord?
Harland knew if Jacob had a poor impression of the house Taran, they could just forget about his friendship. In the end, it all depended on Austin now.
Austin looked at the silver-haired young man, and he suddenly felt he wasn't just merely a random C-rank mercenary like Jonty.
He was full of openings, but Austin has this strange feeling that if he made a move, he might regret it.
Austin smiled amiably and said, "I'm Austin Port, an Eight Rank Junior Knight. I'm here out of curiosity. Please forgive my blunt visit."
Kai couldn't help but looked at his teacher with a hint of a surprise because this wasn't his usual style to talk with these mercenaries!
