Tsunade went to the Umbrella Organization, and after two days of research, she found that the research on Hashirama cells seemed to have reached a bottleneck, and she always felt that something was missing.
This made Tsunade think of her old friend, Orochimaru!
So she immediately found Naruto, who was in Naruto's room. Naruto had just finished meditation. As his strength increased, Naruto also realized his weakness, which was his mental strength.
Although his mental power is already immense, he will still be greatly affected when facing illusions, especially Mangekyō-level illusions.
So he planned to develop a technique that could increase mental power. Although this kind of training exists in the ninja world, or the training of mental power is related to Yin Dun.
Compared with the systematic ninjutsu, the practice of Yin Dun seems a bit simple and rare.
However, Naruto can still use the ability of God's reward for hard work to slowly increase his mental strength through meditation.
Soon after it was over and he was about to go check out the construction site of the Castle in the Sky, Naruto saw Tsunade coming to him.
This surprised him a bit, as Tsunade usually wouldn't look for him unless there was something important.
"Oh, Tsunade, is there something wrong with you?"
Naruto warmly entertained Tsunade. Seeing Naruto's house, which was surrounded by mountains and rivers, it was a real residence!
But she didn't care about this, and immediately said: "Naruto, you should be able to contact Orochimaru, pay attention to my grandfather's cells, I always feel like something is missing!"
"I know you have a connection with Orochimaru. He has already done research on my great-grandfather's cells, so I want him to do research with me!"
Now Tsunade no longer has the same rejection idea as before. After all, Naruto said that if there is a chance, his grandfather and second grandfather will be resurrected in the future.
Then she didn't care. After all, if studying cells was helpful to Naruto, then in the future she would be helping her grandfather and second grandfather to resurrect.
It can be considered a contribution!
"Oh, I didn't expect you to think that. I did work with Orochimaru before. I'll contact him for you!"
Although a little surprised, Naruto didn't say anything and immediately took out his cell phone and called Orochimaru.
Because he also wanted to develop injectable Hashirama cell serum as soon as possible.
"Ding Ding…"
"Hey! What do you want to talk to me about, Naruto-kun?"
Orochimaru's voice came from the other end of the phone.
Now Orochimaru often exchanges science and technology with the Umbrella Organization. In Naruto's heart, Orochimaru can be considered half a member of the Umbrella Organization. It's a pity that Orochimaru has always refused to join the Umbrella Organization.
It's just that since they often cooperate with Umbrella, Naruto simply doesn't care.
Orochimaru was extremely excited during this period, as he had experiments to conduct every day.
He obtained the method of practicing fairy arts from Naruto, and has recently succeeded in practicing it. Not only that, Orochimaru also used it to improve the curse seal, and the corrosive effect was greatly weakened.
At the same time, the power of the curse was increased by 20%!
It's a huge improvement.
"Orochimaru-kun, this time it's not me who's looking for you, it's Tsunade!"
Naruto said with a smile.
"Tsunade...?"
Orochimaru frowned on the other end of the phone. Why would Tsunade look for him?
Never mind, just ask first!
Naruto handed the phone to Tsunade, who saw this and almost forgot there was such a thing as a cell phone.
But she didn't have Orochimaru's contact information before!
This method is indeed faster than using Summoning beasts to deliver messages.
Tsunade answered the phone and said, "Orochimaru, it's me, Tsunade!"
Hearing Tsunade's voice coming from the phone, Orochimaru couldn't help but ask curiously: "Tsunade, I wonder what you want to talk to me about?"
Orochimaru said with a slight smile.
"Orochimaru, I won't waste my words. I know you once studied my grandfather's cells. Now I need your help to develop a serum that can fuse Uzumaki and Uchiha!"
Tsunade said immediately, and her straightforward words instantly made Orochimaru's pupils shrink.
He never expected that Tsunade would say such a thing, and he became excited for a moment. Tsunade's research on cells can be said to be even deeper than Orochimaru's.
After all, Orochimaru is a latecomer, so all his methods seem a bit crude, and his biotechnology is completely based on human lives!
Later on he gradually became a Grandmaster, but now he has also developed his own wild ways.
"Sure, Tsunade, I look forward to working with you!"
From the other end of the line, Orochimaru's cheerful voice came, and it could be heard that Orochimaru was a little excited.
"Um…"
Naruto took the call and said, "I will send someone to pick you up later, and I have prepared the most sophisticated research equipment for you!"
Naruto then hung up the phone.
Naruto immediately made arrangements and called again, notifying people to pick up Orochimaru, of course using the current air force!
...
At this moment, an uninvited guest has come to Konoha. It is Danzo who got the news from Obito!
He even secretly checked whether what Obito said was correct. After checking, he found that just as Obito said, detonating tags were hidden in most of the buildings in Konoha.
And it is very hidden, which is why it has not been discovered for so many years.
If you don't look for it specifically, you won't notice it at all.
It is impossible for the Hyuga clan to use their Byakugan to observe Konoha's buildings all day long.
However, there are no detonating talismans in those family buildings. After all, most of the residences of those families were built by their own people.
The building has existed for a long time!
That day!
Tsunade received the news, and was furious when he heard it!
Danzo appears again and directly threatens the entire Konoha!
Moreover, no one knew when so many detonating tags were hidden in Konoha. Without time to think about it, Tsunade hurried back.
If Danzo were to detonate the Explosive Talisman, Konoha would definitely be weakened to an unprecedented degree.
Tens of thousands of lives will be lost!
When Tsunade arrived in Konoha, he saw Danzo standing with some of the remaining escaped Root ninjas.
Those people have been brainwashed by Danzo and turned into emotionless weapons.
"Danzo! What on earth do you want to do?!"
Tsunade pushed through the crowd and looked at Danzo not far away.
"What do I want to do? Do you remember how you treated me? I am the real future of Konoha. I, Danzo, am back!"
"Konoha cannot live without me. Only I can lead Konoha to become stronger!"
Danzo looks a little crazy now.
"I'll say it again, let me become the Hokage and hand over the power of Konoha, otherwise I will detonate the detonating tag directly and we will all die together!"
Danzo held something in his hand, which was a detonation device that Danzo had developed by combining the detonating talisman!
