By attacking his grandfather with his primary offensive technique, Minos made that attack disappear for everyone watching them fight.
But not only could those spectators see nothing, but Oswald also had no idea where the blows that Minos was throwing while dancing were going.
He could only feel that the attack power of these blades was not small but enough to cause him pain.
'It is more troublesome than I had thought!' He realized the difficulty of fighting against something that could disappear from his senses.
And when he least expected it, this man suffered a powerful attack on his back.
The Spatial Sword had not only evolved to give Minos the ability to make the blades travel through space under invisible subspace. It also gave him the ability to change the direction of his attacks.
That is, he was in front of Oswald, and his first blade should have hit this old fellow in the abdomen. But due to the characteristic of this technique in the current phase Minos was in, he had made such an attack appear behind his grandfather, taking him by surprise.
Swooish!
As Oswald was not fast enough, he promptly felt the attack hit his back and unbalanced him forward.
But the situation did not end there. Soon after, several other blades hit different parts of this elder's body, making him express sounds of pain in front of his wife and daughter.
"Ouch!" He shouted as he realized that Minos was not just attacking him with the normal one of that technique he had shown everyone during his training moments ago.
No, Minos had found a way to combine the Spatial Sword with Chaotic Gravity without having to do the fusion. In this combination, each blade he launched carried a strong gravitational power, which exploded when the energy blade hit something.
As this something was precisely his body, Oswald felt those shock points going through something rather strange to him.
When a blade hit him on the left side of his waist, Oswald felt as if, at the last instant, that energy blade had suddenly been accelerated and forced with much more force against his body.
That increased the attack power of that blade tremendously, making him feel more than he thought his grandson was capable of imposing.
'That's not bad! With a skill like that, he will be able to fight against high-level Spiritual Saints armed with good equipment and techniques!' He was pleased to realize that his grandson still had cards up his sleeve that could help him on his journey through the Flaming Empire.
"Very good, Minos, but a battle doesn't just involve attacking!" He smiled after those words as he showed one of his hands while stretching his right arm forward.
When he did this, Oswald made countless glowing dots appear in the skies around Minos, with ice daggers forming at his command.
Minos saw this and tried to counterattack, using his avatar's space of influence to increase the gravity on these ice daggers.
Crack!
Some of those weapons did indeed break, but since they were creations of a level 79 Spiritual Saint based on a Golden-grade technique, they did not break completely.
Thus, in a few moments, many flew like rain toward the Soul Avatar of Minos.
Indestructible Body!
Minos circled his defensive technique, and the surroundings of his Soul Avatar became brighter in that golden color as if a protective layer had emerged from within.
Meanwhile, dark inscriptions appeared around the avatar's body, making it appear as if it was contaminated.
But this was not contamination, but rather the passive ability created by the Devouring Art, which showed itself fully just as the first attacks were about to hit Minos.
Thus, Minos began to feel large chunks of energy becoming available to him, as he felt as if he was getting a massage from the many weakened daggers hitting him.
He did not stand still while receiving this powerful attack from Oswald and brought his hands in front of his eyes.
Infinite Dream: Shaking Reality!
Chaotic Gravity: Shaking Reality!
At an impressive speed, Minos managed to fuse the two techniques as if this were nothing more than one of his usual techniques.
Thus, as the region between Minos' hands, which looked like a semi-transparent bubble surrounded by colored dots trying to explode, reached its peak, people in the surrounding area were startled by such speed.
"That fast?" Patience shouted as she saw her grandson fuse two techniques and attack Oswald in a matter of seconds.
Maisie stood up from her seat and saw the colored ray departing from that strange blob of air and then hitting her father.
At that moment, Oswald formed an expression of pain, losing much of his focus as he was thrown backward.
'Damn it!' He thought to himself, seeing the universe around him accelerating itself up while his soul seemed to have come out even from inside his Soul Avatar, something impossible to happen.
Minos realized the momentary advantage he gained by surprising his grandfather and activated another of his fusions.
Infinite Dream: Mind Destroyer!
Spatial Sword: Mind Destroyer!
Minos could now use fusions in sequence without exhausting himself so much. But besides this ability related to his 8th technique, due to the amount of power, he had already absorbed from Oswald, either from the previous attack or Devouring Art and his innate ability, he was full of energy at the moment.
Hence, he made a move with his weapon, horizontally striking while having his knees bent, spinning like a top.
Swooish!
Then a big blade, the size of a 10-story building, totally red like human blood, shot out of Minos' spiritual sword, heading towards Oswald.
Even if Oswald realized this, he would not be able to dodge this attack capable of flying at a speed he could not keep up with.
Crash!
Due to his inability to at least realize it at the right time, Minos' grandfather felt his chest armor being hit by that attack, crumpling against his chest and making him feel more pain.
"Ouch!" He uttered that sound again as he fell toward the ground outside the emperor's estate.
Seeing that, Minos lowered his spirits, ending this fight as the victor!
"Impressive!" The level 79 Spiritual Saint said this out loud next to Patience and Maisie. "Your Majesty has already reached a level of power that only the leaders of the Flaming Empire have achieved!"
Gloria heard that and nodded silently, feeling that her husband really could already sit at the table of the powerful in that state, even without his Black Hole Bomb.
'Oswald didn't take it easy on Minos. He may not have used all his strength simultaneously. Still, the previous attack was strong enough to kill level 77 Spiritual Saints, and his defenses were at maximum!'
'He really felt pain, even though he was defending himself with all his strength!' She thought of something similar to what Ruth, Abby, and Maisie were thinking.
Meanwhile, Patience could not help but find it funny about her husband being thrown away by their grandson and smiled. 'I think we're too old now, Oswald... Time to retire and let the younger generation do as they see fit.'
With that decided, Minos wiped the sweat on his body and quickly changed clothes before approaching those people to talk about the current status of their powers.
'Time to start solving our old problems...'
