A hint of craziness appeared in Fujin's eyes and a smile appeared on his face as he thought, 'Hehe, you made your move after all, Danzo. Good. Now, let me see whether you are skillful enough to ensure that the Root survives.'

While the Root ninjas were skillful enough to hide from chakra fields even when someone as skilled as Fujin used it, they had no idea about Fujin's other skill. Even Danzo was completely unaware. He never imagined that the spies he sent would be detected in an instant. If he knew Fujin had such an ability, he wouldn't have bothered sending anyone to spy on him. Even if Fujin didn't retaliate, the spies would only see what Fujin wanted to show them, which could make the Root fall into a trap.

Unfortunately for Danzo, Fujin no longer had intentions to keep playing games. He planned to use this opportunity to completely escalate the situation. On this day, two events would happen that would send shockwaves throughout Konoha that would be remembered for quite some time. One of them would also bring back some unpleasant memories.

Fujin fell back into his bed. Sleep had recovered most of his chakra, but he was still not at full capacity. It was understandable as he had maintained a lot of Shadow Clones. However, in this circumstance, that was a good thing. A Shadow Clone, with 20% of his maximum chakra, appeared next to his bed. Without a word, he disguised himself perfectly and disappeared from the room.

Neither of the 5 Root ninjas around Fujin's house detected the Shadow Clone leaving from under the ground. There were two main reasons for this. Firstly, the Root ninjas didn't dare to openly activate their chakra fields. Secondly, Fujin's methods of hiding chakra were extremely good and his clone left through a place where none of those 5 were present.

Minutes later, Fujin's clone reached the outskirts of the Root Headquarters. He thought, 'Yesterday, I showed up at the front door. However, with a base this huge, I have innumerable ways of entering. Even though this base is very well hidden and protected with seals, Root currently lacks the manpower to defend its main headquarters. Of course, it is also because they don't expect to be attacked in the first place. After all, Konoha will be the one to take the hit first before any attacker reaches the Root Headquarters.'

Danzo had only 26 Root ninjas left after Fujin's stunt 2 nights ago. Out of those, 5 were outside Fujin's house, while another 5 were outside the village training the kids from the Land of Water in a secret location. In addition, 2 were deployed in the Fire Capital, 1 always followed Naruto and 1 was hiding in the Anbu.

As a result, the massive Root headquarters had only 12 Root ninjas along with Danzo. Even among them, 5 of the Root ninjas were in the underground laboratories at the lowest two levels of Root Headquarters, meaning that only 7 were available to keep an eye on their base.

Hence, they couldn't pay attention to every entry into the Root Headquarters. Of course, Danzo had long sealed up such entry points. Fujin's clone was standing in front of one such sealed entry point.

The clone's eyes glowed as he began studying the seals. He nodded as he realized, 'Not bad. Even I will need some time to decode these seals and enter inside without being detected. Not to mention, there are some seals I don't recognize. Unfortunately, I don't have the time to study them slowly. Oh well, even if I did, they would detect me in no time. So, no need to bother with stealth.'

The Blade of the Thunder Spirit appeared in his right hand, but the hilt was covered by his long sleeves. The shape of the blade looked nothing like a sword and instead looked like a ball of Lightning. In an instant, nearly 35% of the clone's chakra was transformed into Lightning and transferred into the Lightning ball.

Such a massive chakra spike just outside the Root headquarters was picked up by the seals. A couple of sensors and Danzo also felt it. Danzo thought, 'What the hell?'

He immediately made a hand seal to activate all defensive seals on the Root headquarters. Unfortunately, he wasn't fast enough. Fujin's clone kicked the seal entrance, smashing it apart before the seals could activate.

Immediately, the 5 Root ninjas in the laboratories activated the defenses to ensure that the labs would stay safe. The two who were with Danzo got on alert to protect Danzo. As for the remaining 5, they ran towards where Fujin's clone had barged in from.

Unfortunately for them, those few seconds were all that Fujin's clone needed to supercharge the Lightning ball with almost 99% of his chakra! As soon as three Root ninjas appeared, he waved his right arm in a slashing action, unleashing all the Lightning stored inside the Blade of the Thunder Spirit!

'Lightning Release: Lightning Flood jutsu'

The Root ninjas who had just arrived were shocked. While they came prepared for war, none of them expected to face such a devastating attack even before they could properly see the intruder! What shocked them more was the massive quantity of chakra they were feeling from the incoming attack despite not being a sensor!

Fujin's clone had supercharged the jutsu with almost his entire chakra. That was 20% of Fujin's chakra. However, with the amplification from the Blade of the Thunder Spirit, the attack was equivalent to 200% of Fujin's chakra!

It was important to know that Fujin's chakra reserves were almost at the same level as Hiruzen's. Though Hiruzen's chakra reserves had deteriorated with age, he was still a formidable ninja and his place in the rank S tier was unshaken.

Very few ninjas had chakra reserves exceeding his. As for the ninjas that had chakra twice as much as him, they could be counted on one hand if the Jinchurikis weren't considered. And, even they would never use up all their chakra in a single attack. What the Jounin-level Anbu were facing was an attack at a level rarely seen in the Ninja World!

The three Root ninjas, as well as the two who weren't too far away, were hit by the Lightning within the blink of an eye! They didn't even have a chance to put up a defense and were obliterated within moments!

Though Danzo had failed to activate the seals on the sealed entrance in time, he activated the remaining seals in the headquarters. As a result, the entire base became very resilient. Every wall could endure a couple of rank A jutsus before crumbling.

Unfortunately for Danzo, Lightning specialized in penetrating through obstacles like walls. And, the attack could be considered a peak rank S jutsu in terms of pure destruction! The Lightning immediately began spreading throughout the Root headquarters.

Fujin's jutsu was a variation of the 'Lightning Release: False Darkness jutsu' and was quite similar to it. The only difference was the amount of chakra infused in the jutsu which caused the nature of the jutsu to change. This change could be seen in the Root Headquarters. If a bystander had spectated this scene, it would seem like there was a Lightning flood inside Root Headquarters, spreading in every direction and piercing through every obstacle! It was a scene from a nightmare!

In his office, Danzo's eyes widened in shock and disbelief as he sensed the amount of chakra in the attack and how easily his base was being destroyed. Standing next to him, Yamanaka Fu nervously said, "Lord Danzo..."

Despite being an Elite Jounin, Fu had no confidence in being able to resist the incoming attack. Danzo immediately weaved hand seals while saying, "Move behind me."

'Wind Release: Serial Vacuum Waves jutsu'

Immediately, Fu and the other Root ninja moved behind Danzo. At the very instance when Danzo was done weaving the hand seals, the Lightning broke through his office walls and moved towards him when he exhaled his jutsu. Several Vacuum Waves hit the incoming Lightning flood continuously and kept bombarding the incoming attack for a few seconds.

The Lightning headed towards Danzo was finally stopped. Only some Lightning charges made it through the intense wind and hit the three of them. They weren't strong enough to cause them any damage.

Danzo and the two Root ninjas with him were safe. However, their moods were anything but calm. Even Danzo was extremely tense. He thought, 'Fortunately the Lightning wasn't all concentrated on me. Otherwise, I would have no chance of stopping it without using Wood Release or sacrificing Shisui's eye by using Izanagi. I didn't even have time to remove the seals on my right arm! Which crazy bastard attacked my base? And who is strong enough to unleash such an attack? Even Hiruzen shouldn't be able to do something like this!'

Though Danzo stopped the Lightning flood from hitting him, it still continued spreading in other directions. Within seconds, 3 underground floors were completely in shambles! Thankfully, while the seals weren't strong enough to stop the Lightning flood, it slowly whittled down the power of the Lightning flood, putting an end to the destruction

Unfortunately, the destruction caused by the Lightning until that moment was too high! The top 3 floors collapsed entirely, forcing Danzo and the two Root ninjas to evacuate in a hurry. If it wasn't for the fact that Fujin's clone didn't target the pillars, the entire base might have collapsed! Thankfully for Danzo, the laboratories on the bottom two floors weren't damaged.

However, the loss was still extremely high! Danzo was extremely angry. Unfortunately, he was unaware that this was just the first step of Fujin's plan. Not a single person in Konoha would even consider the possibility of such a massive attack being merely a distraction! Fujin's next steps would threaten Root's existence in a way Danzo would never have imagined. The only question was whether Fujin would succeed in his goal or whether Danzo would succeed in defending his Root!
