He had the idea of betting to make his incarnation reach that world for two factors.
One of them was Tofesh, who managed to appear again in front of him although he had possessed a body to do it. Moreover, he seemed to have a lot of restrictions.
The other was the Mysterious Expert. Yale didn't know even the gender of that person, but its incarnation seemed to be always near in the shadows, and there was no way to know how many incarnations that person through the universe had because Yale didn't believe that there was only one as it seemed to be always near him.
Thus, Yale decided that if he sent and incarnation and hid it in his disciple's soul, there shouldn't be too many problems for going into a lower universe.
After all, if no one noticed his presence, there shouldn't be too much effect on his existence there.
"We are both Timeless Sovereigns. If that person can act in the shadows without being discovered by others, I can do the same."
Yale's incarnation had that thought in his mind when he started to move without being noticed.
The main problem for Yale's incarnation was that he didn't know how much restricted his interference could be. After all, although Tofesh case was something similar to the Life and Death Trials, it was something different because the levels of the universes affected were different.
Tofesh's restrictions seemed enormous or else he was sure that he would have sent an incarnation using the same method as Yale used, so Yale knew that his restrictions weren't that big.
However, he didn't know anything about the restrictions which was a problem bigger than the restrictions.
"Well, let's investigate it. Without risk I will waste this trip, I just need to be careful. Moreover, the connection with my true body has been cut since my disciple's trials started, so I am alone on this."
An incarnation and the true body were permanently connected, but Yale's incarnation discovered that the connection was cut after his disciple started the trials.
However, he mostly attributed it at the differences in the flow of time which would make the synchronization difficult. Of course, he didn't discard that the universe itself was blocking the connection.
Moreover, since he separated from his disciple, he wouldn't be able to hide again without him noticing something, which would be against the rules because the trials must be faced alone and knowing that your master had an incarnation hiding in your soul was the same as having a secret cheat.
Yale's incarnation never interfered with the trials of his disciple and his disciple didn't know about his existence, so it didn't matter as it was like a hole in the rules because Yale's incarnation had a null effect on the disciple's trials.
Yale's objective by hiding that incarnation at the moment the trials started was to find his old master in the case that his disciple visited that universe, which had nothing to do with the trials.
The trials of his disciple were just a show for Yale's incarnation, who enjoyed them as a spectator. Of course, he also knew all of his disciple's embarrassing moments.
He thought that if he managed to synchronize his memories with his real body somehow, those shameful moments could serve to blackmail his disciple in order to force him to train harder if he had a lack of confidence in the future.
With Yale's prowess, it wasn't too difficult to convert some memories into images for others to see and felt that as long it was just used to motivate his student to train harder, blackmailing wasn't something too evil.
In fact, Yale didn't agree with the methods his disciple used to surpass the difficulties of the trials because although his disciple managed to surpass them, he didn't obtain the best possible result.
For example, Yale had faced a similar situation to the one where his disciple was an enslaved beast forced to obey.
However, in those lower universes, soul enslaving didn't exist, so it was possible to get free of the enslaving.
In that same world where humans ruled, in the era Yale faced his trials it was the reverse and was a world where beasts ruled, and humans were just the slaves of the beasts.
In that case, Yale had also started in a weak position as he was born as the daughter of human slaves. However, at that time, Yale never failed to be successful, and that kind of situation wasn't an exception.
In that trial, he not only managed to get free from the enslaving, he also reversed the supremacy on the world and freed humanity before dying from the injuries provoked in the last battle. It was a heroic death despite living only eleven years in that world.
When Yale's incarnation saw his disciple in a similar situation, he thought that the time for humans to rule came to an end and that his disciple would reverse everything again, but he was disappointed.
That was a world where even immortals didn't exist, so there wasn't any disadvantage for the limitations of the life and Death Trials and was also one of the few chances with high chances of making big things even for someone who wasn't as exceptional as Yale.
However, in the end, Yale's expectations on his disciple were too high. The disciple lived as an enslaved beast until his death.
For someone like that disciple of Yale, it was already a feat not failing the Life and Death Trials, so expecting him to do great things was Yale's overestimation.
Yale spent a week wandering about the city without hurry.
He didn't dare to use the Divine Sense for fear of alerting someone or provoking and unnecessary interference, but he didn't believe that he would be able to find his old master soon, so he decided to take everything with calm.
There was also the worry of ending provoking an interference with the trial of his disciple, so he could just wait until his disciple died and went to the next trial before finding his old master if the situation turned difficult.
In that week, his disciple had already joined the Liye Academy, but he wasn't doing too well since for some reason he seemed to have offended an arrogant young master.
The behavior of that young master was like that of Heruk on the Nacesai Academy, so Yale had urges to cut him into pieces, but he couldn't interfere, and his disciple didn't have the guts to do it in his situation.
Yale felt that even if the young master's family killed his disciple, it would have been a worthy death since it was just a trial.
Paying attention to his disciple was just a habit, but he really hoped that the young master would have a bad ending.
"You, leave the academy or you will be dead tomorrow."
In the campus plaza with a huge statue of Liye at the center, the young master punched Yale's disciple.
"Why? I never did anything to offend you."
Yale's disciple didn't understand why he was receiving that kind of treatment because he has been targeted since the first moment.
"I just hate your face. It reminds me of a hateful fellow who I killed in the past after the girl I liked showed interest in him. Of course, she is also dead for being blind in choosing."
Yale's incarnation was displeased when he heard the reasons for the conflict, but he couldn't interfere.
In fact, it was the big brother of the body that Yale's disciple was using who died at the young master's hands, and one of the reasons for the original owner of the body to went to the city was to find his brother.
"That doesn't have any relationship with me. I joined this academy by the rightful means, and the rules say that only the Ancient Master Liye can expel someone who didn't break the rules."
Although the academy was very lax with the rules and allowed fighting between students, killing someone in the campus was still forbidden, so Yale's disciple believed that as long he didn't leave the campus, the other party couldn't touch him.
"Whatever you say, you peasant! Ancient Master Liye was great, but he was a mere mortal. If it weren't because of his disciples and his own master protecting him, he wouldn't have become someone who required respect. Just wait and see. In some years, this city will have my name, and not the name of a mere mortal who was good at teaching."
The family of the young master was powerful and showed intentions to take over the city several times, but the existence of powerful people backing up the Liye Academy made them act carefully. However, the young master didn't understand why they should be careful when they belonged to the most powerful family in the world.
"Insulting Ancient Master Liye is a sin punished with the expelling of the academy and the city for the rest of your life. Everyone heard his words. This guy has committed a severe sin."
Everyone knew that, but no one helped Yale's disciple for fear to the young master's family.
"I don't plan to help my disciple, but I will act to protect my pride tarnished in this lower universe. This is acceptable even with Tofesh's restrictions, so it should be alright."
