Zabuza said, "Don't worry, I have no desire of joining any criminal organization now."
Kakashi got out of his thoughts, glanced at Zabuza and said, "I have been thinking, shall I tell you how Akatsuki is the reason for the Blood Mist Era in Kirigakure? If you know, you might become an enemy of Akatsuki."
Zabuza narrowed his eyes at Kakashi upon hearing him, "Are you implying that Akatsuki has something to do with how Yagura has been leading Kirigakure?"
Kakashi didn't speak for a moment, and then decided to tell Zabuza and Haku about Yagura being controlled by Obito. "Akatsuki's real leader controlled Yagura. I know you would say he was a perfect Jinchūriki, but believe me, even perfect Jinchūriki's can be controlled. And he was also the same person, who was the reason for our village's Fourth Hokage's death and the Kyuubi Rebellion years back, and your Blood Mist Era at the same time."
Zabuza and Haku froze, bewildered at what they heard. Haku's Clan, the Yuki Clan, was also gone extinct, leaving Haku alone survivor during the Blood Mist Era.
Zabuza asked in a hoarse voice, "Are you telling the truth?"
Kakashi just nodded, with a serious expression on his face, didn't want Zabuza to think he was lying, since he really wasn't. "What are you going to do?" Kakashi asked.
Zabuza's mind was in turmoil now, but he still replied, "After selling Gato's assets, I will return to Kirigakure. If I return, I know they won't directly attack me, especially considering the weak state of the village, they need stronger ninjas, then tell all this about to the current Godaime Mizukage about it. If what you tell me is true, then I definitely am going to kill that bastard, leader of Akatsuki."
Kakashi could hear the clenching fist sound from Zabuza, who was very angry; this also goes to show, how much he actually loyal to Kirigakure. Haku also looked at Zabuza, with some worried eyes. If someone can be the reason for two great nations huge loss, then his organization would definitely be more dangerous, and Haku didn't want Zabuza's life in danger because of this.
"I have been hating Yagura all the time, but he himself just turned out to become a puppet of someone," Zabuza muttered, self-blaming himself for hating Yagura for decades, considering him the evil he needed to get rid of for Kirigakure.
"Well, think about that later, first tell me, what to do with this, we didn't need Gato, but do you need this mansion, want to sell this later as well?" Kakashi nudged Zabuza and asked.
Zabuza looked at the dull-looking Gato, several killed mercenaries and the huge mansion behind him, he nodded, this mansion alone would sell for Millions.
Kakashi also nodded, and took out a kunai, handed it to Gato, and said, "Here, slice your throat with it, and finish your useless life."
Gato, under Kakashi's Genjutsu, did as he was told, and died instantly. Then Kakashi looked at Zabuza and Haku, waved his hand, "Alright, for now we should go our ways, and I know we will meet each other again, after all I also have to take down Akatsuki organization."
Zabuza said, "I know, you already told me earlier, if I join it, you would hunt me down in the future, you also probably want revenge for your Fourth's death."
Kakashi just nodded, he didn't want to go into details of what real reason he wants to take down Akatsuki, but let Zabuza think what he wants. With that they parted ways, and Kakashi dispersed his Shadow Clone, getting the real location of Tazuna's house, since he himself wasn't there.

With Body Flicker Technique, he quickly reached the place, where Naruto, Sakura and Sasuke had been sitting in the dining room, with Tazuna, his daughter Tsunami but his grandson, Inari was not present there, not like he cared.
"Did you take down Gato, Ninja-sama?" Tazuna asked, a hint of anticipation.
Kakashi didn't reply him, just nodded, and sat around with his students. It was only afternoon, so they were having lunch. Tazuna, seeing Kakashi's nod, didn't doubt him, was overjoyed that Gato was dead.
For the next few days, Team 7 stayed there, before returning back to Konoha. Meanwhile, news of Gato's death spread like wildfire, at first no one believed, but finding that not even a single goon of Gato ever came to the Village till then, they started to believe, and the construction of Bridge went smoothly and would be completed in the next few weeks, at an even leisurely pace.
Though Gato was dead, but the bridge was still important for them, as it's important for the economic survival and independence of the Land of Waves, however Kakashi didn't stop till its construction completed, not like they needed them, plus Tazuna couldn't even have them to wait.
_________________________________
Upon returning to Konoha, Kakashi made the report to Hiruzen, told him about Tazuna's lie and killing Gato, but obviously not about taking his money, and also not anything important about Zabuza and Haku, aside from his fight with Zabuza. Tazuna obviously had to pay for the mission as a B-rank one, which was divided and given to the team.
Naruto complained, "Man, this was a really boring mission, we didn't get to fight anyone."
Sasuke also nodded, he also wanted to fight, but Haku didn't let them find him, Demon Brothers instantly became paste, that was actually Kakashi's miscalculation, he himself didn't want that, plus Gato and mercenaries were definitely not where he wanted to take his team.
"Don't worry, in the next mission, I will let you fight whoever the enemy is, plus you no longer have to do D-rank missions, only C-rank or higher for you." Kakashi reassured them.
Hearing this, Naruto jumped up, clearly overjoyed that no longer labor missions. Sasuke also sighed in relief, though he never complained about D-rank missions like Naruto, but he also was quite dissatisfied with them. Sakura however, had stopped doing them for some time, focusing on medical Ninjutsu training only.
"Then when will be our next mission, Kakashi-sensei?" Sakura asked. Naruto and Sasuke also looked at Kakashi, who thought a bit, not about mission, but about when would be better time for that next.
Then he said, "Firstly, take a few days of rest, then I will teach you Jutsus I promised, and then will we do the next mission, take it around two weeks or so. And till then, maybe Sakura, you learn something about healing techniques a little usable right."
Sakura wasn't so sure, she had just started practicing practical training in medical ninjutsu, two weeks or so still wasn't enough for her to properly able to learn anything better, though little bit might definitely be the case.
Sasuke then asked, "Are we going to do training alone till then?"
Kakashi surprised, raised his brow and asked, "I thought you were mostly interested in getting stronger for now, and training is important for that, or is that you no longer want to do training?"
Sasuke immediately shook his head, "No, It's not that, I was just asking."
Kakashi nodded, it would really be surprising for him, if Sasuke really saying no to training, he then took them to Ichiraku Ramen shop, treated them to Ramen, have some light conversation with them and finally all went their ways.

Kakashi, finally in his room, sat crossed legs and summoned his system panel, it had been a total of 2 weeks for the Land of Waves mission, if he waited for bridge construction, maybe it could also have gone a complete month. But his Chakra reserves had increased quite a lot, now almost close to Three times that of Hiruzen approximately.
[Host: Kakashi Hatake]
[Chakra Pool: 856,980/882,500]
[Chakra Control: 91/100]
[Chakra Level: Kage]
[Chakra Affinity: All]
[Chakra Growth: +20,000 per day]
"Yeah, tomorrow my chakra really will be close to 3 times higher than that of Hiruzen, and in next week, I will even touch complete Million, maybe Raikage no longer gonna be close to my reserves."
Kakashi muttered aloud, his chakra really growing at a very good and fast pace, and with that he also started to feel many changes within him. He properly didn't feel his chakra growing, expected when it's increasing at fast pace, only giving him the feeling that it's always like that but during this mission, with each day, he felt a lot of energy inside him, not about Chakra, but like he can work all day long without getting much tired.
"System only said to increase my chakra reserves, and nothing else," He pondered, "What could be the reason then? Chakra is consists of Physical energy and Spiritual energy, maybe as my chakra grows, my Yang and Yin Release also grow?" He shrugged, he isn't entirely sure, but yeah, that could also be the case, since Yang Release also represents Vitality, healing, and physical energy afterall.
