Blake woke up the next day when the sun was rising.

'Ok, let's start the next day in this bizarre world...'

Blake then ordered the jaguars to hunt for breakfast while organizing his thoughts over his class.

'What improved me was the development of the perception by training and both activate skills by comprehending its effects.

'So, maybe the passive skills are improved through training while the activated skills are through comprehension.

'However, it seems that my "Energy Manipulation" didn't improve even though I used both in the meantime.

'Is it because I'm misusing them?

'But how is the right way?

'I guess I will figure it out as I improve other areas.

'I didn't discover how to produce undead energy from thin air yesterday, so today I will focus on improving my abilities.

'I had some ideas on how to experiment with them.

'Firstly, I want to test the ability in insects.

'As cells, some insects usually live for a short period of time, procreate and die. But, what if they are undead? Can they procreate as crazily as they were alive?

'Secondly, I want to study the undead ability to absorb life energy. I noticed it previously, but it was just too little that I ignored it. Now is the time to understand it.

'Lastly, can an undead keep their memories from when they were alive?'

Then the jaguars brought a small animal from the jungle to be Blake's breakfast.

After eating Blake direct went outside the cave, whereas in the whole jungle, there were a lot of mosquitoes.

Blake then waited for his prey to fly close to him and 'Clap'.

he clapped his hand as fast as he could, killing the mosquito flying near him.

He kept the hand with the dead mosquito standing while taking an undead leaf from his pocket with his other hand.

He then smashed the undead leaf with the same free hand and guided the undead energy to the mosquito with his spiritual energy and input more spiritual energy inside.

The mosquito then turned into an undead mosquito. However, it couldn't fly. One of its wings where severely damaged by Blake's clape.

Blake was a little disappointed, but it was only bad luck. Hopefully, the next one would be able to fly.

Blake couldn't differentiate the gender of the mosquitos, so he decide to make a few more undead to ensure that the experiment would work.

He then repeated the process and killed eleven more mosquitoes. Unexpectedly, four of the new undead mosquitoes had not damaged the wings and could fly. But, they were still very damaged.

Blake then ordered them to procreate and see if any of them would lay eggs.

The undead mosquitoes then started to interact with some plants or kept moving around Blake. Until, unexpectedly, one of them went inside the cave.

Blake followed this undead mosquito and saw it laying some eggs near a watering hole. However, Blake could feel death energy coming from the eggs. Which means that they were already dead.

That disappointed Blake, but he took it as just a temporary failure. He decided to continue to research it when he had improved his skills.

Blake then decided to go to the next experiment. He ordered the undead under him to absorb a specific tree's life force. What he noticed is that the tiger's absorption was the strongest, since he could absorb more life energy in less time. Moreover, the snake's was the weakest.

'I theorized that it was due to its physical status. But it could also be the amount of damage in the body because the snake is the most damaged, with two bites in the body, and the tiger is the least, with almost no damage.

Support the author by searching for the original publication of this novel.

Moreover, I can't feel where this life energy goes. I thought it would go inside the undead, but I can't feel any energy inside the undead except the undead energy.'

Blake then searched for another small animal and found a capybara again. He ordered the snake to bite it and transformed the capibara into undead with the same amount of damage as the tiger. However, the capybara absorbed even less life energy than the jaguar, which proved Blake's first theory.

Blake continues to test the life energy absorption from the undead species during the whole day.

...

Meanwhile, inside the jungle, a tall and muscular man was on top of a pile of four goblins while holding another dead goblin, without both arms, in one hand and an iron sword in the other.

There were four stone knives tied around his waist and two stone spears tied to his back.

He then threw the dead goblin to the side and clean the blood on his sword with his arm.

The man then said in an imposing tone:

"System"

[ System Window:

Name & Level: Absko - Starter Tier 5

Class: Martial Artist

Passive skills:

Mana perception (15%)

sword Art (3%)

Spear Art (2%)

Knife Art (2%)

Active skills:

Energy Slash (25%)

Energy Cut (25%)

Half Moon Slash (10%)]

'I improved again. Fighting really is the best way for a martial artist to improve.

'That's the fifth group with the same distribution. One of them holds an iron sword, which is the strongest, and four of them hold two stone knives or a stone spear.

'I think they are some kind of hunting time. Therefore, there should be a village around.'

"Michael!" Absko said in a high tone.

"What is it now?" A man, sitting with his legs crossed a few matters away from the battle scene Absko left, responded.

"There should be a goblin village around here, can you find it?"

"Of course I can, but why should I tell you? Ether you and I have classes focused on combat. We need to fight to improve faster. What if I don't want to share my experience with you?"

"I am already Tier 5."

"Congratulations, now I have one more reason to NOT tell you."

"I mean... I can give you a very painful teleportation back to the castle hall."

"And then you would have no means to find the village quickly. Dumbass, stop being stubborn and give me what I want."

"Fine! What do you want to know about Sophia?"

"Just her age back on the simulation and what she used to do for a living. Oh, and of course, if she was really a girl back in the simulation."

"Of course she was a girl, what do you take her for? And, she used to be around her thirties, she was a physician and I don't know which area of physics she studied. Oh, moreover, she was engaged with a very handsome man."

"I didn't ask this last part."

"But I thought it was good for you to know.

"Now, the village!"

"Fine, thanks for the information."

Michael then put his hand on the floor and close his eyes.

Absko kept himself in silence as a statue during the whole process.

A few minutes later, Michael opened his eyes, and without taking his hands off the floor, he said:

"I got it. I can guide you there. But, I will also fight this time."

...

In the evening, Blake was still researching the life energy absorption ability that his undead has.

He was near an undead capybara that was touching a bush inside the cave when the undead capybara exploded.

'It seems this will be a long research...

'During the day I only made three significant discoveries:

'First, the life absorption depends on the stats of the undead.

'Secondly, the undead that has no brain, or any kind of way to control its actions, will constantly absorb life energy at every contact with anything.

'Thirdly, There is a limit on which the undead can absorb life energy at once before exploding. The high the stats are, the higher the amount will be. The capybara showed it just now.

'Wait, looking at that information I can see a pattern. The stats determine both of the main factors of this ability. Moreover, the stats also determine the amount of spiritual power I need to use to transform it into my undead, because the stronger the stats, the bigger the amount of death energy released as I observed earlier when creating my first jaguar.

'Moreover, thinking back about the process the undead is made. The death energy is all absorbed by the undead energy before being input back into the body. The death energy is made of life energy.

'So the undead energy replaces the life energy.

'Therefore, the stronger the stats are, the bigger the amount of life energy.

'The more time it takes to turn the species into undead, the weaker it gets. And the damage also decreases its strength because the life energy stored in that place cannot be perfectly replaced by the undead energy.'

'Continuous on the absorption, the bigger the amount of undead energy, the bigger the amount it can absorb.

'So what absorbs the life energy is the undead energy, not the undead itself. Moreover, considering the fact that it explodes when absorbing too much, it probably holds it inside and lost control, but the undead energy around the undead didn't allow me to feel it before.

'Concluding everything, the undead energy is spent, similar to my spiritual power, to absorb the life energy. When the amount of life energy surpasses the amount of undead energy, the undead explode.'

Blake waited for a few instants after this conclusion and, in the end, became disappointed. He didn't improve after adding this big discovery. He thought that tremendous reasoning would be enough to increase a Tier.

'Wait, if I take what I just conclude as a fact, why do undeads store life energy? I guess it is to improve themselves. I got it'

Blake directly ordered the tiger, who he experimented with previously the absorption of some life energy, to kill one of the three lemus he had been imprisoned in the cave during the day.

He then saw the death energy being absorbed by the tiger while his amount of undead energy increased.

'I was right, they turn the same amount of undead energy into life energy with the life energy absorption, and when fused into undead energy again with the death energy, the total amount of undead energy increases, and their stats increase as a result.'

Energy start to overflow from Blake's body, and he felt as breaking another barrier inside.

He was now a Tier 4.
