Typically, when someone is Cultivating with mana, they will firstly use the mana they are gathering to form a core, which they will be using to store mana from thereafter.
They are also many cultivation methods where the cultivator does not use mana to cultivate but rather some other energy which is different from mana. One of those energy is the one Nil is currently using.
Now, moving the little particle of Nothing he could currently move at the moment, he guided it towards his heart, which he absorbed.
He could feel the effects immediately— his heart beat almost speeding up, but it did not speed up, neither did it increase.
Then came the one that is usually the most agonizing, his heart almost tearing under the pressure of Nothing, folding on itself and expanding beyond its normal size at times.
Furthermore, the speed at which it takes for his blood to circulate almost doubled even when his hearbeat did not increase.
And one had to know that the little he was able to move to his heart and absorb is not even able to saturate a single cell of his heart.
That said, the most noticeable fact of all is that, through all those pain, all those agonizing moment, Nil never cry out in pain.
His will holding steady.
He never whimper.
He never gasp.
He never exhale in order to let the pain out.
His face never twitched, always kept neutral through it all, as physical pain is something he have transcend.
After the little particle of Nothing has been properly saturated, he then reach out to more, guided them towards his heart before absorbing them into the same cell that was partially saturated before.
And he could feel it now, that single cell have been perfectly saturated, so the next particle he gathered he moved them to another cell closer to the saturated one which he began to saturate too.
And over the next couple hours, Nil only continued four process.
Sense Nothing particles, pull it towards his heart, dump it there then absorb it

*Rustle*
*Rustle*
His cloth brush against the sorrounding leaves which rustled as he stand up after hours of cultivating.
"Solaris, how long have i been cultivating?" The man said to the air.
[Over 40 earth hours master, however not up to 2 earth days.. of this universe.]
The same voice as that of the system sounded in the man head, but now it did not sound robotic anymore but inching towards a man voice.
Furthermore the voice was reluctant to add the 'of this universe' because it does not seem pivotal, however, the voice added it because its master might consider it not giving him complete information.
"Ok." The man replied.
Previously he have planned to use at minimum 3 days to cultivate, but he had been able to manipulate the Nothing here at much lesser cost of his will due to this universe being new and the Nothing here being more docile than most he have come across, so he was able to completely rewrite his entire organ, heart to be precise, with Nothing.
"We have to find something to eat." The man mumbled on his way forward, heading aimlessly into the wild.
He simply wanted to go hunt, not because he is hungry but because his body demanded it, he needed the energy after using all he had before while cultivating.
And, although he could have found a prey by now if he want, but rather he kept walking aimlessly into the wild not trying to track any animal as it is a perfect opportunity for him to map out his current sorroundings.
Because, what type of assasin will not even know the terrain they are living at, or even the advantage and disadvantage of that terrain?
On his way he have found some animals on his way, which he could hunt, but he simply left them, find another way and continued mapping the terrain, drawing a map of the nearby terrain in his mind.
After knowing the ins and out of the area, where some animals marked as their area, how many are there, are they any pack of animal around, how many are in a pack, he finally head back.
But he did not simply head back, he first head back to where he had found a deer before.
When he got to where he found the deer before he did not find it there, so he traced the footprint of the deer and fortunately he was able to locate it in less than an hour.
After spotting the deer, he hid in someplace, inside some of the tall weed near it, and he maked sure not to make the weed rustle.
Unfortunately, the place where the deer was hibernating is open ground, very far from bush area, the distance between him and the deer now is currently over 50 meter, not something he can cover without the deer noticing him.
He has some multitude of choice now he can take. The first is—
Assassinate it: with his skill as an assassin he could carefull approach it and assasinate it.ll
The second choice is by using his Ether, With his ether being able to assume any form, he can make his ether assume the form of a bow and arrow then shoot it at the unassuming deer, killing it off.
"I think I'll go for the third choice." He declared as in the next second he run at an impossible speed for his mass.
Defying the which states that speed equals
Furthermore, he defy not only one law at that moment, but two. With the second being the law which states that force is directly proportional to mass×acceleration due to the umprobable force he attack the deer withm
One moment he is hiding in tte bush and the next moment he is already in front of the deer and its head rolling on the floor.
It could not even register the pain before dying.
