Daily life like that continues to happen, Akasha follows Erina's orders as they are without complaining. Time went on until one day something happened.
"Argh!"
Akasha began to moan in pain more often because of something, even though she wasn't hurt but more and more often Akasha moaned in pain.
Erina initially thought Akasha was just pushing herself but the longer it went on, the more unusual Akasha's condition became. So Erina used her magic to see Akasha's condition which is strangely usable today.
Akasha's condition can only be described as horrible. The muscles inside Akasha expanded horribly inside Akasha's tiny body.
A child has a relatively weak body, they have not yet formed their body properly but have great potential.
A child's body is less stable than that of a teenager or adult.
Children's bodies also make it difficult for them to gain the same muscle mass and volume as teenagers and adults despite doing the same exercises, which can happen because their bodies struggle to build muscle.
A person's muscle volume and mass can increase if they train, but that can happen when people are in their teens and above because their bodies are starting to form.
But what happens if it happens at the age of a child where the body is still not fully formed and not ready to accept such things.
There is a swelling of muscles in the body that has difficulty increasing in a small body, it makes a collision reaction between the body and the muscles, each muscle tries to merge with the body but the body has difficulty accepting the muscles.
It was this that created the excruciating pain that Akasha was now experiencing.
Even the pain tolerance Akasha developed was nothing compared to the pain Akasha was now experiencing.
Akasha's body should have been destroyed due to the swelling of the muscles inside her, but thanks to Akasha's abnormal regeneration, Akasha's body was not destroyed but resulted in Akasha feeling continuous pain every second.
Despite this, Akasha continued her training relentlessly without understanding that Akasha's muscle mass and volume continued to grow which made it even more painful.
And on the 11th day since the muscle swelling, Akasha's pain began to lessen thanks to her pain tolerance starting to develop once again.
But it wasn't just pain tolerance that developed, Aaksha's body also developed to adapt to what was happening to Akasha's body.
There was significant growth in Holo's body, Akasha grew taller faster and the volume of weight and muscle mass also increased.
Now Akasha's body was able to adapt to Akasha's increased muscle volume and Akasha's body decided to increase Akasha's body development faster which made Akasha experience faster height growth.
Then Akasha's body began to form more perfect muscles that were stable between the body and the muscles.
Akasha's body successfully adapted and found a solution to Akasha's condition.
"Compression."
Erina murmured seeing Akasha's condition, Akasha's body condition now began to stabilize between every part of the body and Akasha's muscles.
Compression, a simple but difficult method to do on the human body let alone a child's body.
Compression means making the muscles pressed drastically until they become very dense into Akasha's body which is only a child.
Because of the compression, it is not strange to call Akasha's muscles now very hard. But thanks to the compression method, Akasha managed to solve her muscle swelling problem that almost blew up her muscles.
But there was a price to pay for increasing the speed of growth and stabilizing the body and muscles.
It was an excruciating pain as evidenced by Akasha who continued to moan in pain continuously, perhaps this would be one of the most horrific pains in Akasha's life at this time and in the future.
"Urgah!!!"
Erina heard the cries of pain from Akasha who was trying to sleep but was having trouble due to the pain from behind the cabin and could only remain silent.
Erina looked up at the sky, what she saw was a beautiful full moon.
Although the scenery looked beautiful but there was someone who was in great pain right now.
Erkna could not be happy to see the beauty of the nighttime full moon for the first time.
Despite this experience, Akasha continued her training as usual.
(Do you have to do this until your body breaks like that? Why don't you rest for a while?)
Erina had been thinking like that a lot lately. She couldn't stop thinking about Akasha, what Akasha really wanted, whether it was so important for Akasha to become a Mage Of Justice that Akasha had to endure all this.
Erina had often told Akasha to stop but Akasha never stopped and just smiled softly saying that she was fine.
Erina had often tried to help with healing magic but Akasha's regeneration took up the task and gave Akasha more suffering.
But the biggest reason why Erina did not help Akasha was not because her job was taken away by Akasha's abnormal regeneration ability but simply because Erina felt that she should not interfere in Akasha's journey on this standing path.
Erina was simply amazed and in love with Akasha's dazzling determination and perseverance.
Erina had once encountered the same person as Akasha, Erina's Master, that person went through a very difficult and impossible path with only courage and strong persistence against the First Mage and Demon King alone, a strong determination that could break any boundaries.
Erina caught a glimpse of her master's shadow from behind the little boy's back.
...
It had been 9 days since Akasha's relentless screams of pain began, Akasha was starting to not scream as much anymore thanks to her ever-increasing pain tolerance.
Not just thanks to pain tolerance, but it was also thanks to Akasha's body starting to adapt to muscle compression and perform muscle compression more efficiently and less painfully than before.
...
It had been more than a month since the muscle compression process, by this time Akasha's body had fully adapted to the muscle compression and managed to perform the muscle compression perfectly without any side effects.
And it was at that moment that this world succeeded in creating the first human who had fully crossed the human limit in the past 100 years, and the only first human to successfully reach the superhuman realm at the age of 8.
