After she left, Ainz realized he might have been too hasty training his mental energy at this time of the day, it wasn't that his decision was wrong, but he needed an atmosphere where his mother wouldn't be able to see him, otherwise, she might just start worrying again, which was something he didn't want to see.
While it might seem like he was overthinking, if she were to discover the type of cultivation technique he was training from his master by mistake, she would likely want him to quit and that was something he was trying to avoid at all cost.
As Ainz was thinking, the system kept sending him notification messages that the pain was going due to the activation of wyvern regeneration, but he totally ignored it.
'I spent more hours than the last time training in the sea of consciousness, I could probably stay for more hours if I forced myself, however, if Mother were to come and see me in the state I was before, she might end up creating a scene.'
[Wyvern regeneration activated]
Ainz ignored the notification message, as he looked outside the window of his room and saw that time had not gone far as he had thought due to staying in the sea of consciousness for long, there were probably still about six or seven hours before midnight.
After a while, he couldn't help but shift his attention to the books Lilith had brought to his side.
'Phantom spear art and eight gates of asura.' Ainz quickly went through these names, before picking one of the books, although his master didn't like his decision to train in the eight gates of Asura, he still knew that was the only way for him to get stronger faster, especially when he was already lagging behind the main family bloodline.
The first book he picked described the spear art, as he began to read it in his mind, Ainz hissed a bit before ignoring the pain it caused to his head, thanks to wyvern regeneration he wasn't worried about whether the pain would increase or not.
After going through it Ainz nodded his head, although it was a low-rank martial art than what he would use when he was monarch, nevertheless, it was still a complete martial art, even the usage of mana was much more detailed compared to the technique he had acquired before.
Ainz couldn't help but wonder, although one was a cheap imitation and the other was a complete art, he wondered if there would be any difference if he merged the two together, would the rank of the spear art increase a bit? Or would it remain the same but slightly different?
Although he wanted to test it out, he thought it would be better if he trained in the spear art first, to activate the true power of the spear art, he needed to understand how the mana was being moved according to the specific rhythm and pattern of the technique, and then synchronize the movement with the right body movement.
'Although, I would have loved to train it now, but at this point where my mind is being healed by wyvern regeneration, it might cause more harm than good, however, in the morning I can start to practice it.'
After closing the book, he turned his attention to the suitcase beside him, and opened it, inside of it were three segments of a spear, that when joined together would make a complete weapon, its quality seemed to be greater than any of the weapons he had seen or used from the weapon shelf in the training yard.
'Although it's still crap compared to what I used back as a monarch, nevertheless, it's still far better than not having anyone one.'
After that he looked at the book containing, the eight gates of Asura, however, just as he was about to read it, he heard a knock on his door, and he quickly hid it away, behind the door was none other than his mother Lilith, just like she said she had not only come to check on him, she had also brought, plenty of meat and rice for him.
Unbothered about the strong headache he was experiencing and the nausea he was feeling at the moment, Ainz forced himself to eat throughout the time Lilith was there, since she kept giving the death glare each time he slowed down or stopped, until she left Ainz forced himself to eat.
After she was gone, he locked the door and began studying the information contained inside the eight gates of Asura.
'For these years I have been deeply searching the various forms of body cultivation techniques, using various means at my disposal, pillaging, killing, and stealing to perfect my cultivation technique. Even so, I could only create the eight gates of Asura, I do not have much time remaining.
'I have trained in all kinds of body cultivation techniques, in more than a century of being a cultivator, I went from being a lowly cultivator to creating the eight gates of asura, out of all the techniques I have seen this is the most powerful, yet the most dangerous, the further you go, the closer you are to the death.
According to what was in the book the creator of the eight gates of Asura, was a martial art fanatic who was a cultivator, who wanted to surpass his limits even at the cost of his life, however, he realized his technique was incomplete, so he kept merging different techniques, and would train in them for days, weeks, months, and years, his experiments wasn't done on anyone other than himself.
Because no one would best be able to explain, how effective the techniques he had created were other than himself, at the end of his life, the eight gates of asura was created, but he was already too old to teach anyone the correct process of training it, and those who trained in it afterward ended up dying.
