"W-what ?! You're leaving ?" Said Kushina still shocked by the statement of Zoro.
Kurenai decided to stay silent but even her felt shocked and reluctant to see Zoro go.
"Yes, I need to go on my own for some time." Said Zoro
Kushina was extremely reluctant to let Zoro leaving, she felt that life would not be the same without him around.
Kurenai was keeping silent while wearing a sad face.
"Is there nothing that we could say or do that will make you stay ?" She asked seriously
"No, I need to do this but I have no problem if you want to meet up in the future, you two have my phone number." Responded Zoro
Hearing that Kushina and Kurenai sighed in relief, at least it is not definitive.
"When you want to meet up ?" Asked Kushina somewhat relaxed
"How about 1st September in York Shin city ? There will be a huge auction there." Proposed Zoro
"I heard about that but that's in 1 year and half ! It's too long !" Said Kushina with annoyance
"I need time to train and to fight too." Said Zoro as he began to grow impatient, why they are so adamant to keep him here ?
Kurenai sensed that if she let these two arguing they will fight so she quickly calmed them and accepted the term of Zoro. It will be the 1st Septembre in Yorsh Shin City.
"I suggest you both to take the Hunter Exam that will begin this month, with your ability you will have no problem, after that you will have to create some Hatsu and train in the advanced Nen technique." Suggested Zoro as they have yet to train in the advanced technique or even make their Hatsu.
For Kushina it will be simple as she is an enhancer like Zoro but Kurenai is a Manipulator so she have to think about something for her Hatsu.
"What about you are you going to take the Hunter Exam ?" Asked Kurenai curiously
"I will take the next one." Responded Zoro as he turn his back to the girls
"Well take care you two, next time we see each other it will be in York Shin City and don't forget to grow stronger because I definitelly be stronger next time we see each other." Said Zoro
Kurenai and Kushina were sad that he was leaving but quickly became determined, Zoro would become stronger so they too have to grow stronger to assist him in fights in the future, they would not be left behind.
When Kushina and Kurenai made their resolve Zoro was already out of view but Kushina quickly remebered something...
"Now that I think... How would that Baka go anywhere he want with his shitty observation sense ?" Said Kushina
.

"BWAHAHAHA" Kushina was on the floor holding her ribs laughing like a madwomen.
Even Kurenai was giggling.
After Two week
Zoro has no idea where he is now but paid it no mind he finally found a place suitable for training. It was a mountain with extremely low temperature and it was perfect for refining his body and strengthen his already monstruous will.
And so for the first 6 month he began to train his Armement Haki to the extreme, now that he was alone he could train seriously and without any distraction, as such he have much more more time to train so he sliced his training between Physical, Haki and Advanced Nen Technique such as Gyō and Shu. After mastering Gyō and Shu quite fast Zoro began to train his Ko and Ken and like the rest he mastered them fairly easily and fast.
After that he began to train his Observation Haki and for that he completely shut down his three dominant sense and began to live like that and fight with beast with just his body alone and using his Observation Haki. His progress were monstruous and his Observation Haki can now : sense people around him with a 1km radius, sense emotion and intention of a person in front of him and his premonition in a fight were faster, he felt that he was near Katakuri level in term of Observation Haki but that he needed to fight strong opponent to breakthrough. In parallel he trained his body and attained a terrifying physical strength. Durability, Agility, Dexterity, Speed, Reflex, Time Reaction, Body Mouvement... he refined all of this to the extreme and all of these category were top-notch now. In these time he trained his En and his In, he didn't really need In as he was an enhancer but maybe it will be handy so he learned it. He was truly talented for the En it somewhat like the Observation Haki so he mastered it quickly and with the quality of his Ten and Ren, he can make a En of 250 meters and maintain it for a long time. After training his En and In, he trained his Hatsu. Zoro is an enhancer so his Hatsu came naturally in his head, he decided to keep all his Swords Based technique and add them Shu and Armement Haki and the result were destructive.
After 1 year of training, Zoro only have 6 months till the Hunter Exam so he decided to train 4 months his Conqueror Haki and strengthen and maintain his Ren and Ten. So in this 4 months he tried to control his Conqueror Haki and it was quite difficult, in the first month he has attain no result but after some meditation and enlightenment he understood and has shown complete control of his Conqueror Haki after 3 months, in the whole training he always has his Ten or Ren around him and now he can maintain his Ren for 4 hours and his Aura quality developed much further. He noticed that the quality and quantity of his Aura were at least 3 times bigger than when he arrived here and it doubled again when he gained control of his Conqueror Haki. As he didn't train his body these 4 months he has trained his Swordsmanship more and sharpened all his styles. Overall Zoro has improved a lot but he needed experience in Nen battles so he made his mind, there was a big city near so he decided to work as Bounty Hunter like in his past. The Hunter exam is in 2 months so before that he will try to fight a lot of Nen user to gain experience.
He didn't know that his choice will lead him to a certain spider.
