After Roja came to this world, he was practicing Haki, Tempering his flesh and practicing his sword, and all of that is to upgrade his soul sword which brought to him many powerful sword abilities.
he had to change the way he practiced, he has to constantly strengthen his soul and the way of the swords.
For Roja, with a casual look, he could tell that his soul is actually a soul of a Shinigami, If he was in the world of Bleach, he would've already learned how to get out of his body and use his powers directly.
But unfortunately, he wasn't there.
Moreover, If Roja was in Bleach's world, he will only be able to use his own Zanpakuto, he won't be able to borrow the powers of others like he is now.
"Without the aid of external forces, if the soul was powerful enough he could break the shackles of the flesh and that would happen only if the soul is far stronger than the body."
Thinking to here Roja shook his head.
His tempered his body too much, if he wants to make the soul way stronger than the body, then he will need a long time to do it.
And if he did, maybe his soul would be at the sixth or seventh stage already, he wouldn't need his own power then.
"Another way is to make the body weaker, which will weaken the shackles and make it easier for the soul to break it… Perhaps it's for that reason i entered that state briefly."
Roja shook his head slightly, he can't always be in a battle, does he need to stab himself a few time to do it? it's simply nonsense.
Perhaps he can stab himself and live as a soul.
But he wasn't in Bleach's world, he was in One Piece's world.
This is a serious issue!
"The last way is to make the soul and the body resonate so that the shackles of the body won't bind the soul anymore, which will let me enter the Shinigami form as I like."
From those three methods, the first one is no good as he had to give up his powers until his soul get stronger, the second is no good too, the third is the only way.
The power of the soul and the power of the body had a connection or the power of the Shinigami and the powers of this world, and that is Haoshoku Haki.
After practice, he could use Haoshoku as he liked, with no bound and so on.
The body and soul are, after all, linked.
…
The next two months, Roja stayed in the fifth level in the Impel Down, His practice made almost all the prisoners frightened.
Because from time to time, Roja will release his Haoshoku.
Sometimes just a little bit, sometimes he would make all prisoners around a certain range drop unconscious.
Roja's Haoshoku is too powerful, the people with bounties up to one hundred million would directly faint without a way to resist.
"The previous thoughts were wrong, The Shackles between the body and the soul never existed in the first place."
While training, Roja gradually overthrew his previous theory, the so-called the shackles of the soul, The connection was from another kind.
It's like a human body, the muscles under the skin, the bones in the muscles and the internal organs under the protection of the bones and muscles.
Without a soul, the body would lose its meaning of existence.
Within these two months, Roja was trying to break the connection… control the connection, to make the soul cover his body, not the opposite.
In this process, Roja had occasionally appeared in the state of Shinigami once or twice, but it was still unstable, the shortest time, it disappears instantly and the longest is a few breaths.
Om!
Roja closed his eyes and sat there, suddenly a tyrannical Haoshoku burnt out, but it didn't spread as it condensed around Roja.
"Almost 20% complete…"
Roja opened his eyes and nodded slightly.
In these two months, he almost controlled the connection to a 20%. For him to completely master the Shinigami state, he would need to control at least 51% of it, and with 100% control, he would have perfect gasp over that state.
In the process of controlling the connection, Roja increased the energy value by a lot.
The fourth stage: the soul of the delicate sword +6

Last month he already upgraded the soul sword to +6, and now after a month he already accumulated enough energy for another upgrade.
This speed is faster than even the last stage.
"Upgrade."
A golden light flashed and upgraded the soul sword again.
The fourth stage: the soul of the delicate sword +7
