Its been 20 years since Nova started training, thanks to time dilation feature of infinite World there is only some hours passed by in real world.
Despite being trained for 20 years Nova is still 16 years as his body is aging according to outside world time.
This 20 years have been fruitful for Nova as his current self can now defeat thousands of his 20 year old self with a flick of his finger.
This is mostly due to the 18 hell soul arts, this art description is crappy but once Nova started practising this art he knows he found a buried gold. This art allows him to create 18 Bright hell orbs, other than their given description which states that he can use this orbs to devour his enemy soul and purify own soul, this small orb can be used as weapons. They can be fired at his enemy as bullets that bypass any physical defense and only targets soul, can cause explosion when commanded dealing AOE soul damage, passively protect his soul and can also be used to torture others soul.
There uses are still being discovered by Nova, his True splitting sword art also reached the final stage.
The True splitting sword art consist of 4 stages namely Earth splitting, Sea splitting and Air splitting, the final stage being Void splitting.
This art follows the pattern of splitting heavier objects to almost non existable objects. Thanks to this art Nova mastery of Splitting Rule reached 80% making him a 20 % away from the perfection of Sword master realm... If not for the other requirement which he found out after learning in Eternal library. To reach Sword master realm peak he needs to learn two more rules, which are rule related to stabbing or piercing and a rule which gives his sword a meaning. For the stabbing rule he comprehended the rupture rule upto 71% but last rule which give his sword a meaning is still not understandable by Nova.
According to Celes Sword meaning rule is basically why one wields a Sword for some it can be conquest, for some its killing or simply guarding, Nova is unable to find his own rule because he lacks battle with real people, battling with emotionless puppets can't give emotions to his sword therefore he has to wait until he fights real people.
As for his Origin Mage path he is already at the middle stage of Ancient runes making him capable of altering laws upto middle class galaxy level.
Lastly his limitless mana art is now peak of second stage whick is myriad origin opening stage. A normal person can only have a single source to store their special energies like mana, spirit etc 'except anomalies of Nova world people, they can basically have different source by binding different beasts though it's limited to 3 beasts per people' but this limitless mana allow Nova to create more vessels for his Mana.
Originally he should only have Mana core where he would store his mana but the second stage of limitless mana art made some new vessels or sources namely Circles around his heart, sea of consciousness and mana veins or meridians through out his body.
This new sources increased Nova absurd mana by another 30 times, 10 each, as they are peak of their own rank like pristine pure rank of Mana core.
His sea of consciousness especially became his trump card as the mana their is not sensable by any means.
Aside from these old arts Nova learnerd three more arts namely Dragon incarnation art, Dream sword art and void light art.
Dragon incarnation art is for his Hell flames, this art allows him to shape the Hell flames into tangible entity in the form of a Dragon, the dragon are of many types, to learn this art perfectly Nova has to study anatomy of the dragons perfectly making him aware of Dragon physique more than his own.
Dream sword art is a Soul based offensive art, this art has a interesting description therefore Nova choose it.
Name : Dream Sword Art
Rank : Unique
Description : One day Sword Master son woke up from his dream and asks his father if has he ever cut a Dragon. His father laughs at him and told him only a Sword saint who can Wield the power of absolute cutting can Cut the Absolute Defense of a Dragon and I am only a humble sword master. Hearing this his Son said than I will become a Sword Saint, his father encourages him him that he can do it.. But deep down he knew his son don't have a talent for Swordsmanship rather he is a once in a million Magus talent. After few years the small boy accepted his talent in magic and become a Magus in just 150 years, he already forget about his dream of slaying a Dragon, Until one day his Son asks him if his Magic can slay a Dragon,hearing his son words he remembered his dream and after another 30 years he made a soul sword art and slayed Dragon with it, he named it Dream Sword Art because everything started with a dream of a small boy.
This Art as its name says can utilise the power of the soul to slay a Mythical beast that harness the power of laws to protect himself giving it a moniker of Absolute defense.
This art has only one stage called Dream remberance, it is powerful attack that concentrates all the soul power into a single critical strike bypassing all laws protection. This art is also the most difficult art Nova has ever practices as this requires a origin grade rule to work with called Phasing Soul rule.
This Rule can make a soul strike bypass even origin Laws of reality making it a absolute ruler in his field of soul rules. Nova has only comprehended 1.001% of it but it's still enough to even kill him despite him having passive protection of 18 Hell soul art, one can only pray for his enemies who didn't even have have a soul protections.
Lastly his Void light art can make light appear out of nothingness to be utilised by him, it's purely support type art, he didn't choose any offensive or defensive art as his Light Domination allow him to dominate light as he wishes, there is only problem of not having light as without light what he gonna dominate so Void light art his perfect choice.
And now all his preparations are done, he is ready to travel to his first new world.
