Although this [Undying Fortress] sounded very domineering and somewhat like a cheap, emasculated version of Susanoo, in reality, he had turned Aoba's own defense into a ranged defense, then enlarged it to form an illusory fortress to protect more people.
The biggest advantage was that the defense effect of the fortress was constant, and it would not be affected by attacks or physical deficiency.
But this could not cover up the fact that this was a pure auxiliary skill!
This was because during the activation period, not only could he not move, he could not take the initiative to attack. Otherwise, his ability would lose its effectiveness and enter a cooldown period.
Moreover, although activating this ability did not require him to consume his physical strength, the moment the skill ended, all the damage he suffered would be returned to him.
In fact, it was equivalent to him transforming into this 'Undying Fortress'. He still had to endure the attacks that he needed to endure. Even because his size had increased, the attacks he would receive would be more. It was just that there was an additional delay in time.
However, in comparison, the stronger his defense, the higher the upper limit of [Undying Fortress]'s defense. In the end, the true damage he would receive would be smaller.
Perhaps when the skill level rose, the damage ratio would be further reduced.
Although it was a little useless in normal battles, in general, this ability was very suitable for some special moments, such as now!
Being protected by [Undying Fortress]'s light and shadow special effects, although Itachi and Gekkou Hayate did not know what Aoba did, they knew that they were temporarily safe.
Although the range of the LV0 [Undying Fortress]'s special effect was only one meter and a half, the effect was really good.
Especially when Aoba was extremely narcissistic and set the light image of Stronghold as his own image, the enlarged 'War God Aoba' was so handsome that it was a bit rotten!
Especially under the shocked expressions of many Kumogakure Ninjas, it made him look even more heroic!
"What kind of ability is this?" Gekkou Hayate asked with a somewhat excited expression.
"The new move that Kekkei Genkai developed. It is still a half-finished product. This is also the first time I used it." Seeing that Kumogakure's ninjas were all shocked by him, Aoba relaxed a little and muttered in a low voice.
Gekkou Hayate was suddenly speechless. They were both the owners of Kekkei Genkai, but why were you the only one who was so outstanding while I was constantly being beaten?
Could it be that the method I used was wrong?
Gekkou Hayate suddenly had some doubts about life. He also made up his mind that if they could really return alive, he must develop his Transparent Escape technique well. Otherwise, if he were to be left too far behind by these two perverts, he really wouldn't be able to even look at their backs!
Itachi, on the other hand, had an expression of 'I knew it'.
It was very clear that he was not the only one who had gained something during this period of time. Aoba's growth speed was actually much faster than he had expected.
Itachi was very emotional in his heart. In the time he had first known each other, he had only used three body techniques and Shuriken to abuse each other in different ways.
But now, even if he used his full strength, he might not be able to win.
However, he did not feel any frustration. On the contrary, the stronger Aoba became, the happier he would be. Then, he would continue to spur himself and squeeze out his hidden strength!
It was time to enter the 'Itachi God 2.0 era'!
"Uh, what should we do now? Just stand there and do nothing?" Gekkou Hayate asked curiously when he saw that Aoba did not move at all.
"It's not that I don't want to move. It's just that this move has a lot of limitations. Once I move or take the initiative to attack others, I won't be able to maintain this defensive state."
"Ninjutsu that can only be beaten and can not fight back? You really have it!"
"Gan! I shouldn't have saved you just now, let you die outside!" Aoba, who had his sore spot poked, was a little angry.
At this time, Itachi suddenly asked, "What is the effect of this move? Can it only defend? Then can we attack the enemy standing in the middle?"
As expected of Itachi, he asked the key point in a short time.
Aoba thought for a moment and explained, "The effect of this move is actually to enlarge my own 'Kekkei Genkai'. There is actually no change in the defense itself, but it can protect more people. At the same time, I will enter a special state. As long as I do not take the initiative to move, no external force will be able to force me to move."
"As for whether you can attack people from the inside to the outside, I am not too sure. You can try."
Itachi nodded and then immediately stabbed the 'layer' in front of him with the short knife without any trace and found that it was directly blocked.
"Physical attacks are ineffective, outsiders can't get in, and the people inside can't get out."
After making the first attempt, Itachi immediately made the second attempt.
Sharingan, open!
Itachi, who did not hesitate to consume his chakra again, instantly looked at the unlucky Kumogakure Ninja, and then the Kumogakure Ninja was immediately pulled into the illusion.
After the successful experiment, Itachi immediately closed Sharingan's state and saved his chakra.
At the same time, he finally confirmed that this move of Aoba could only defend against the 'tangible attack' inside and outside, such as Ninjutsu, physical attack, and so on.
But it could not stop the attack of the spiritual side, such as illusion!
Since the illusion that he cast on the external side of Kumogakure was successful, it meant that the illusion on the outside could also attack the person on the inside.
However, the question was not a big one. Among Kumogakure, there were very few ninjas who were proficient in illusion techniques. Moreover, with him around, the one they were least afraid of was an illusion-type ninja!
More importantly, it was very difficult for the other party to know this weakness.
However, in less than a minute, the attacking Kumogakure ninja also organized a counterattack, and the momentum seemed to be even greater than before.
They did not believe that with so many people on their side, they would not be able to break the enemy's turtle shell!
As a result, a new round of attacks was launched.
However, under the protection of [Undying Fortress], Aoba and the other two were still safe and sound.
However, at this time, Aoba's face became more and more ugly because these attacks were only temporarily resisted and absorbed by [Undying Fortress]. When the skill time was over, they would return to him in one go.
This made him recall the evaluation of this skill by the dog system again.
Invincible?
He was quite invincible, but he would die even faster after his invincible state was over!
He could only hope that his constant defense state was strong enough to make most of the attacks become 'ineffective attacks'. Otherwise, he might be like Zoro, who had absorbed all the pain in Luffy, feeling good at one go!
He would be safe and sound if he carried on.
If he can't, then…..
Noticing the change in Aoba's expression, Itachi couldn't help but worry, "How long can you hold on?"
"At most ten minutes. There might be less than five minutes left."
"What's the price? This type of ninjutsu can not be without a price!"
Itachi suddenly realized this because with his understanding of Aoba, if this move could be casually used, Aoba would never wait until the most critical moment to use it.
Moreover, when he blocked the first and second waves of attacks, he had already noticed that Aoba did not show any joy, but his expression became more and more serious.
There must be something that Aoba did not tell them!
After Aoba heard Itachi's question, he was amazed at Itachi's keen senses but pretended not to hear it.
It was useless to say more at a time like this, so he could only give it a try!
