The first thing he checks is the All three Haki. He has seen it in the anime. So with the "Instructive Muscle Memories" skill he can use it to some points.
He first used armament Haki and on his hand. As he did that his hand completely turned black. He uses his other hand and touches the Haki coated hand. "Tough and hard, but alsoI flexible at the same time." He said to himself.
He then looked at the training dummy in front of him. And punch it with his full force. *bang* his fist made contact with the dummy. But to his surprise his hand came out from the other side of the training dummy.
This is not any ordinary training dummy. The Gremory family brought it from the demon world. This is made from very strong materials. Not any high class devil can destroy it with a single punch.
Millicas take out his hand and look carefully. He didn't feel any pain from the punch. Not even a scratch is left on his hand.
Millicas smile and thoughts "when I master this Skill I can fight Ultimate class devil with just my high class devil power."
He then uses his observation Haki. He closes his eyes and starts to sense everything around him. Soon things start to clear around him. The world around him is turned into a lack and white picture. It's because he closed his eyes.
Even though he closes his eyes he can see everything. Like he hasn't actually closed his eyes. Soon the senses even spread outside. It spread all around and crossed the training room.
It continues to grow in size. After a minute it covers 500 meters all around him.
He can see everything within 500 meters radius. He saw Akeno and Rias chatting in their room. Koneko is actually trying on the clothes he bought for her.
Kiba is cleaning his sword with a very serious face as if he is thinking of killing someone.
He can't see one place though, it's Chysis room. It's like a blank space in his Haki.
He then saw the maids and also outside the building and on the road. He saw people walking on the road in hurry for something.
After another two minutes Millicas stops using the Observation Haki and smiles.
Millicas then thought of something and asked Yuki "Yuki, will my eyes become blind if I use Tsukuyomi?"
[No, it's not the Sharingan you bought but the skill.]
Millicas sigh in relief, When Yuki suddenly says,
[You have High level regeneration you know. Even if it's the sharingan, you won't become blind.]
Millicas eyes widened and then smiled awkwardly. "I didn't know that, it works that way too."
[...]
Millicas then said "okay buy me "swordsmanship" skill."
[10,000 points Deducted, "Swordsmanship" is added to the skill.]
[ASP: 103,000]
Millicas looks confused, "why is it cheap?"
[it's your experience with the sword that makes you strong not the skill.]
"Then isn't it too expensive." Millicas said speechlessly.
[No, every skill that has potential is expensive. You are just lucky that you bought a skill that needs experience to make it strong.]
Millicas suddenly smirks and smiles evilly.
"Okay, buy me Oden Experience from One piece."
[100,000 points deducted, experience orb is in the Inventory]
[ASP: 3,000]
Millicas looked at his last 3,000 experience and sighed. He was rich just a day ago. But now he is broke. But he is not worried. When you have a rich father why care for money too much. He promised to get him bodies.
He then takes out the orb which is like a white ping pong ball with smoke like thing inside. He is excited. This will kill 3 birds with one stone.
Because of his "Instructive Muscle Memory" skill he can learn the Haki in just a matter of seconds. He can also learn pure swordsmanship instantly. Plus he can get enough fighting experience with the Sword.
"Yuki, merge it."
[Experience orb is Merging 1...10...70...90...99..100%]
[Merging complete]
With that he gets all the fight and training experience of Oden. The orbs are very specific. They will delete all the unnecessary information from it automatically. And oden life is mostly about women and sex.
But he was still a genius when it came to sword fighting. He also has very strong control over all three types of Haki.
Millicas stood on the ground with his eyes closed for like 10 minutes. He suddenly opened his eyes and smiled.
He again coated his hand with Armaments Haki. But this time it turned dark Red. He smiled and let go of his Haki.
He then notices that he has a passive Observation Haki 100 meters around him. This passive haki will notify him if there is any danger around. With enough reaction he can avoid this danger. It's a life saving skill.
He then walks to his left, where many kinds of weapons are hung on the wall for practice. He took out a normal sword and held it in his hand. This weapon is perfect for his size. He is now only 5 feet tall. He is sure that in another year his body will grow to complete adulthood even though he will be 9 by then.
It's his perfect Health skill that increased his growth base on the world and its power. This is a high class world with powerful beings. He is also a pure high class devil. So his Perfect health started to act and fastened his growth.
Millicas holds the sword in his hand and he feels like he has been using it for all of his life. He then casually swings his sword to his side and a dark red air blade comes out. It reaches another dummy and passes, throws it and hits the wall next.
*Gasp* a gasping sound comes from behind Millicas. He looked back and saw that Kiba was standing in front of the door and looking at the dummy and the wall.
There is a deep mark of blade in the world. Also at the moment half of the dummy's body slid off of its body and fell on the ground.
Kiba looks at the Dummy on the ground and start sweating. He then looks at Millicas with surprise, awe and a little fear.
Millicas look at the dummy on the ground and look at Kiba and smile. He moves his index finger in front of his lips and gestures to not tell anyone.
Kiba immediately nodded his head and looked at the dummy and the deep mark again. He gulps his saliva as he looks at them.
After a while he calmed down and his face turned serious. He looks at Millicas and walks towards him. He bowed towards him and said "please teach me swordsmanship."
Millicas looked at Kiba, bowing in front of him seriously. He knows about his urges for revenge. He looked at Kiba and said "big brother please stand straight. You know that we Gremory see our peerage members as a family, don't you? You don't need to bow to me."
Kina stands straight and looks Millicas in the eyes. He is still serious but his eyes softened a little. Millicas then continued "as for teaching you, I can do that. But the training won't be easy."
Kiba thumped his chest and said "I am ready for any kind of training."
Millicas nodded his head and said "okay then I will teach you. You can also have your revenge easily. And after that you can become a true knight for Aunt Rias."
He then became serious and said "Promise me that you will protect her with your sword and I will teach you."
Kiba was shocked that he knew about his revenge. Then he thought that Rias must have told him. He then became serious again and said "I will do that. I will protect Rias if she ever needs it, even with my life."
Millicas smiled and said "okay then, you can start training tomorrow. Take a rest today, We will start your training tomorrow."
Kiba smiled and nodded. He then looked at the wall again and left the training ground. He isn't in the mood to train now. He will start it tomorrow. A real sword training.
Millicas look at his back and smile. He knows that Kiba was coming here so he purposely showed him his skill.
He actually felt pity for him. He is a lot better than that red lizard. At least use more brain than him.
He also has good potential for swordsmanship.
