Next day after meditating Nebula feel subtle change but she is not satisfied so today she is doing something different,
Nebula is in the ground, sweat on her face with heavy breaths,
She is standing with her sword and against her is Celestial, her own spirit
Celestial is smiling like mocking her but his every movement is smooth and his words not giving bad feeling
"You can do it Master, you learn the swift, push and Strong Strike, you just need to learn Fatal, critical, Double and Piercing strike" Celestial said but Nebula who learning the things for hours collapse after hours of training
"You, you are a monster" Nebula on ground said
"I am a Spirit, Master and you want to learn the "True Sword Arts", i am just helping"
Nebula remember when Celestial told him about True Sword Arts, a type of arts combined physical energy with body movement to kill people, when she knew that by Master it one can easily fight against someone of higher Rank and kill them, she was eager but not now.
"I thought that someone like me who know everything about swords can learn it easily but i can only understand the basic after this much time and my years of training" Nebula said, her voice is like a child complaining.
"You are very good, understanding the three and using it is also good, you are not basic, you grow and the strike have more speed and power in it" Celestial said, he want to make her more confident.
"Thanks" Nebula said and meditating to recover her energy without Celestial.
Nebula knew that Celestial is her spirit but she don't want to depend on him completely, he is support not her core of power.
"Well, it was good" Suddenly Professor Corralena who seeing them said.
She move and ask "Why are you doing this, I don't think she need this training" she see towards Nebula "with sufficient knowledge, her magic and your powers it is enough, why putting this much pressure on her?"
"I am not putting pressure on my self, we just passing time, Cellena and Alfred break their limits and doing personal training with Department Head's permission so i am learning how to use sword" Nebula said
Corralena understand this and said "why learning something that you know?"
This question shut them both because the Technique they use are similar to basic Technique taught to every people start as warrior, it is same but also different at same time, they confused about how to tell,
"Let me Show you" Celestial said creating a blunt sword
Corralena seeing this also pick a blunt sword from the side "come at me" she said
Nebula to protect herself go outside the Battle area, she want to see the real action,
"You are a Rank 4 spirit so i adjust my powers according to that" Corralena said
"I am a Warrior spirit so don't need to hold back, i can exert power higher than my rank and you are judging me here" Celestial said get ready
Corralena understand so she thought, try to use her full power
Celestial said and move fast reaching near Corralena instantly but the thing faster than his feet is his sword
"Clang" "clang" "clang"
It is very fast {swift Sword} not have much power but have speed which have to be but it hold more power than it should be, Corralena stop it easily but still she is shock.
"It is strong, how?" Corralena ask
, she don't understand it, she can use it but not this much fast and strong compare to her rank.
"Because i master it" Celestial said let her understand "The {Swift Sword} you use is basic Rank one however my is Perfect Class, fully mastered".
Corralena nod and Celestial again move.
He this time not move fast but his sword is hold by both hand, a huge force came with a Shockwave create by the clash of both swords.
"It is {Strong Strike} that multiply the power".
Another Strike, a clash and Corralena feel a force try to push her back but due to her power, balance and warrior stance it is impossible with this much power.
'It is nothing like i have learn' Corralena think 'even we use same technique, he is leagues above me'.
Nebula see this she knew Corralena not using her full power, just one by tenth of her true power at most even that at some important movement, still it is amazing.
Corralena is taking Celestial seriously and suddenly she feel a strike on her abdomen, a force.
"It is piercing strike that can be dangerous if you are not this much strong" Celestial said.
Corralena understand, she is peak Rank Human, even someone reaching the upper limit and her body is stronger than any natural metal, her body can survive in lava and no normal and basic enchanted metal can cut it, it should be either high Rank weapon or Magical weapon that bypass her defense.
Celestial push his weapon but the power and sharpness of weapon is not enough to hurt her.
"Amazing, you are really, a peak Rank Human Warrior" Celestial said
"Thanks, your power is also great" Corralena comment back.
Celestial just started and Corralena knew it, soon hr move and a swift strike from corner to a vital place.
Corralena use swift strike stop it, even it is not dangerous but her instincts came.
Celestial move again and his Blade look like a blur, Corralena stop it but it came again from different angle to strike,
"{Double strike} known for its damage but have lower power, your every strike impress me and showing me my flaws" Corralena said also using {Double strike} but her power is due to her Rank and proficiency in weapon not in skill and she push Celestial easily many steps.
Celestial feel the frustration and so he hold his sword with full power, he is using all of power in his body, controlling the flow and ready to strike.
Corralena understand it is the {Fatal strike} so she stop holding back and stop the attack, she feel the power but there is no effect on her, however the air shake with the crash of power and then the push came.
"Arggh"
Celestial feel pain by the kick, it doesn't hurt like human but he loose control over his physical created body,
Celestial use his body movement and he start attacking.
Swift strike, Double swift strike, Double Piercing Strong Swift Attack, Triple and Four Critical Piercing Strong Strike,.... and so things are going.
Corralena feel pressure, the attacks continuesly growing in power as it becomes more complex, she feel awe when facing these fused sword techniques and can't hold up.
'I knew them for so long but still don't habe this much depth, the fusion, the combination of Techniques' Corralena feel frustration and so she wants to end it.
"{Six fold Fatal Strong Piercing Critical Strike} Celestial use a Dangerous attack that is pushing his physical body to the utmost limit.
"{Full Force : Strong Strike}" Professor Corralena use a basic Strong Strike but with full physical force.
The result was simple, a wave strong enough to break stones, pushing metals back created by them, Corralena for a second stop Celestial's strike and then push him in the Air.
Celestial flying back, unable to control himself crash into the wall.
Normally spirits don't get hurt like humans but Celestial in physical form get all his bones crush by the crash with strong enchanted stone walls cover by magic Barriers, his bones get crushed and blood came out of his mouth.
"Argh, Khek" Nebula at side cough up the blood due to energy imbalance and she also feel the pain Celestial feel.
"Ah, Nebula" Professor Corralena seeing this shout and go towards her to check her and support her
"No need, i am fine" Nebula said, she sat and start recovering, Celestial while leaving his physical form start resonating and recovering.
"Congratulations, you win" Nebula say, however she never think this will happen.
Corralena kneel before Celestial in orb form "I admit defeat please share the knowledge with me, i want to learn".
