Hours before the raid on human experiment lab.
—-
Hidden leaf village.
In hokage office, the forth hokage, 'Minato namikaza' was doing his paper work as usual and thinking about the problem of resent disappearance of uchiha and hyuga clan members on their missions. First few years back some of the village ninja were also disappeared without leaving a single trace, but after year of investigation it was found that the disappeared ninja were all had unique traits and bloodline, so they confirmed that some one was targeting them, and after even more investigation, it was found out that not only leaf village, but other villages were facing the same problem.
As the investigation continued they found, that someone is doing human experiments on the missing ninja's, so the investigation became more serious but suddenly the disappearance of ninja's were stopped, so they could not find or do anything about it, but it started 2 ago again but this time only uchiha and hyuga clan members were disappearing.
After getting serious questions and problems from the both clans, another serious investigation started, but even after a year of hard work they did not get any where near the problem, but suddenly a year ago some news about someone creating a more powerful bloodline line then hyuga and uchiha came and everyone was shocked, after that bits and pieces of news were leaked time to time, and information about the location of the experiment, but all locations were not accurate but 2 out of 10 locations would results in success, it was that of minor success but they couldn't find the main source of this problem, and uchiha and hyuga clans were pushing and putting more pressure on this matter.
As minato was thinking of this problem one of ANBU come from the shadow and said something to minako. " I see, so orochimaru was behind all this missing ninja's all these years, and he was the one who was creating more powerful bloodline, this makes sense why we can't find the culprit." Minato muttered under his breath.
" The culprit was under us all the time so we couldn't find anything, and some one among us was helping him do all these experiments and covering orochimaru from the shadows from within us." As Minato said that the door of office opened and two figures walked into the office.
" Minato I got the news and rushed here, so I can help with the situation,that was made by one of my student." Said with a sad voice was the short old man, he was none other than hiruzen sarutobi the third and previous hokage.
" l also come here to lend some of my root ninja's." Said danzo with hurried voice.
Minato looked at danzo for a moment before answering third hokage. " no need for that. sensei, and also please don't take what I am about to say next as a disrespect."
"No, say what you want to say without holding back." Third hokage said with sad voice, he thought this was his mistake if he were to done a good job of raising his students this problem would have never come, so he was not worried about what Minato has to say.
Minato Knows what the third hokage was thinking so he looked at him sympathetically one last time. " I think some among the elders of our village were supporting orochimaru in his experiment, so I would like to go on my own without needing others help." Minato said last few words looking at danzo with sharp eyes.
As Minato said that third hokage also noticed that Minato was looking at his dear friend danzo with malice sharp eyes, third hokage knows that Minato after becoming hokage knows some of the dark side of the village that was moving towards the peace of the village, and one of them was danzo who was hell bent on eliminating uchiha clan and his previous doings in the name of "for benefit of hidden leaf village", so he did not pursue the matter any further, as he was not the hokage now and he also thought of stopping danzo from doing dark things but he was not strong enough to stop that, and he already passed the will of fire to the next generation, so he didn't go any further and stood there as Minato started getting ready to go out.
Danzo also noticed Minato's sharp gaze at himself, and stopped getting involved in this matter further as he already knows Minato is not like his friend sarutobi, who will be easily manipulated in the name of benefits of the village, and he was the one that leaked the information about human experiments and other things about orochimaru, he knew the experiment was failure and it was not showing any results of getting any better results that it already gotten, he knows that the experiment results only got oneself slightly stronger and slightly better at regeneration but it was only temporarily because all the subjects could not use chakra longer periods of time, so danzo backed off from this matter, not to get Minato's suspicions right about one of the village elder covering orochimaru's tracks and that was danzo himself, he already moved his people from that experiment facility, so he stood there as Minato flickered away.

As Minato reached the location they got from information leak. Without hesitation Minato dived into the experiment lab, after going through all the traps and other illusion techniques, he reached the basement where some people in the white cote trying to escape after finding they were found doing human experiments, Minato ordered his ANBU and elite ninja's team to capture everyone of them with out leaving any one behind, Minato himself was going and searching far orochimaru who was source of all this.
After going through all the rooms in the research lab, he came to halt at a big metal door room that consisted large numbers of traps, explosives paper bombs, sealing and illumination array formations, after getting rid all of them carefully as he opened the door to only to see orochimaru's clone disappearing in smoke. Minato was enraged and was about to go after him but stopped seeing something in the corner of his eye.
Minato was stunned looking at all the babies in a green liquid containing tubes of 6ft height, he couldn't help but sigh and look at the condition of the babies first and he can go after orochimaru later, now these babies safety comes first as he started walking around the labe and looked at the babies one by one. As he was looking at the babies they started opening their small eyes slowly but because of the green liquid they couldn't open there eyes fully.
Notice that Minato ordered his team to carefully take out the babies from the container, and take them to the leaf village. but as the elite and ANBU team carefully took the babies out of the container slowly and carefully, the babies started crying and thrashing around as if they were in some kind of pain, to this ninja's team members started using medical ninjutsu and other pain relief ninjutsu, but as soon as their chakra touched the babies some of them stated bleeding and some even burst like a bubble and some turned into stones.
To this shocking situation and how the babies were dying left and right, Minato asked one of his teams hyuga clan members see what's wrong with babies with their eyes, so they can find out about what is happening to these babies, after looking at the babies with his eyes for a few minutes. " their body can't handle chakra because of some unknown reason I can't see, and their chakra points are all over the place, as they can't seems to support their body and it's like it is doing something one second and other things on another second, like they are doing lots things at a similar time." Said the hyuga clan member with a sad voice. " and these babies can't use chakra in the future as their bodies are falling apart as the chakra is infused in their body." Completed his sentence with sad expressions on his face.
Hearing this Minato ordered his team members take the few alive babies carefully to their village and leave them at the orphanage without telling about the origin of the babies, and Minato ordered his team to never to disclose of what they found out about in this room, as they left Minato silently used one of his secret jutsu to erase the memories of what happened in the last room in the experiment facility on all his team members, and also asked them to arrange a meeting with all the elders of the village as soon as possible.

Next day at the hokage office, Minato sat in front of all the elders of the village and also clan elders of the village, minato greeted them all and started talking about what happened yesterday at the orochimaru's human experiments lab and what he was able to found out about orochimaru's experiment, and after briefing everyone about it, he started ordering them to get full intelligence about what was going on that experiment location, by using mind probing jutsu to the respected clans and dismissed the meeting.
He also ordered them to find orochimaru's whereabouts and put a large amount of bounty on him, as the clan elders were leaving minato stopped uchiha and hyuga clan leader and asked them to stay behind.
As everyone left and only three of them remained minato started talking. "As I already told you about what happened in experiment location, there was something I didn't tell in the meeting because it only concerned about your two clans." Saying that minato paused and looked at them and continued without giving them any time to talk.
"In the meeting I told you about how orochimaru was creating more powerful bloodline by combining other clans cells and other things, what I did not tell is that orochimaru succeeded in that experiment, but only using uchiha and hyuga clans members, in natural way by breeding between your two clans, but the born babies were not strong enough to hold your clans bloodline power and could not use chakra and died for some reason, so I asked one of my teams hyuga clan member what is happening to them, so he stated that their chakra pathways were not supporting their bloodline, and they can't use chakra, so only few babies were left alive and bought to the village and no body knows about them, so I want to ask you both that in the future if you found any of the children having characteristics of your clan without being members of your clan, I ask not as hokage but as MINATO NAMIKAZA to not harm them or try to take their eyes from them." Minato said as he sincerely bowed to them, and also added.
" I already erased memories of my team members about the children and their origins, and I am only telling you both because it concerned both of your clan's and the children." Saying that Minato looked at them.
As both haishi hyuga and fukagu uchiha looked at minato the hokage bowing to them, they also had understood he was doing for the safety and concern for those babies.
Fugaku uchiha understood that he can't do anything about this matter because their clan was already in a bad relationship with village and some of its clans and elders, there were many who were trying to eliminate uchiha clan and minato was not one of them, so fugaku uchiha had to give some face to minato now or he will also start targeting uchiha clan and it is not good for him or uchiha clan, understanding this fukagu don't say anything and stayed silent.
But unlike uchiha clans situation hyuga clans were in good terms with everyone. "I understand what you're saying minato but we can't let outsiders have our clans eyes, it's a tradition that we carried throughout many generation so I can't be lenient now." Haishi hyuga said looking at minato.
But minato did not say anything and just looked straight into haishi's without breaking eye contact to show his sincerity, to this haishi contemplated for a few minutes and said, "Ok I understand minato you're serious about this matter and not try anything to the babies." Saying that he paused for a moment and haishi also looked at minato with unwavering eyes and continued.
"But you also have to understand that I have follow my clans rules and order, so I want check on the babies, if the babies have our clans eyes implanted I will take them to to our clan and the babies will be raised our clans tradition, but if the babies were born with natural means as you as I and our clan will not pursue this matter any further." Haishi resolutely said looking at minato.
To this minato also understand where haishi coming from so he agreed to it, minato was also confident that babies were naturally born with characteristics of both clans and not artificially implanted, so he guided the way for both the clans leaders to check their suspicions.
