Genetic Engineering

Hiroto appeared in Tobirama's lab and he looked around. He saw Tobirama reading a few reports and then comparing it to other reports.

Hiroto appeared at his side and asked, "How far have you progressed, Granduncle?"

"Here, read them," Tobirama said as he gave the reports to Hiroto. After reading the reports, Hiroto had a stunned expression and he said, "You have already found a way to change genes?"

"Yeah, but I still need to see them and then experiment on them."

"Hmm, Then you can get a Byakugan, improve it, and then use Byakugan to see Genes. I am sure Byakugan can see through genes. Or you can ask Kaguya after all she... Fuck!"

"Hmm? What happened? What did you remember?"

"It's nothing. Though I guess it would be better if you gained a Byakugan. Didn't Toneri have one? You can use it and then try to experiment."

Saying this, Hiroto disappeared from the place and arrived near Kaguya. He saw her sitting and trying to control Natural Energy with half of her body already converted to Rock

'What is she doing?'

Hiroto looked at the side and saw Katsuyu. He looked at her and asked, "What is she doing? Did she reject your help or something?"

"Yes Hiroto Sama, I told her that she would become a rock if she lost control over Natural Energy, but she told me to not interfere and let her do whatever she is doing."

Hiroto sighed as he heard this and he appeared at Kaguya's side. He controlled the Natural Energy in her body, calming it down, and then he said, "Now try to control the energy. I will gradually lose my control over the Natural Energy, and you keep on regaining it."

He first removed Natural Energy from her lower body, and because of this Kaguya change back, and now, he controlled the energy in the body and when he felt a tug, he loosened his control over the energy.

Hours later, Kaguya could control the Natural Energy in her body, and now she has to create Senjutsu Chakra by combining Chakra with Natural Energy.

Even though her control of Natural Energy isn't good enough, her massive chakra reserves counterbalance the Natural energy in her body, giving her time to control the remaining energy.

"Now you just have to increase your control over Natural Energy, and then mix your chakra with Natural Energy. When you can create Senjutsu Chakra easily, try to increase creating speed and then change all Chakra in your body to Senjutsu Chakra."

"You can use Shadow Clone Technique to increase control of Natural Energy, while you practice creating Senjutsu Chakra, after all, you have to find your own ratio."

Hiroto explained the process and then he got a reply from her, "What do you need?"

"Huh?"

"Why did you come here?"

"I wanted to ask, Can you see genes in my body using Byakugan?"

"Yes."

"What about thoughts, emotions, and feelings?"

"Yes!"

"Then I need your help regarding the Genes in my body."

Kaguya created a Shadow Clone and said, "Take her, she has One Tail worth of chakra and she will be able to help you."

Hiroto nodded at her and then disappeared from the place with Kaguya's clone. As he left, Kaguya opened Byakugan and looked into her body. She compared the genes she saw in his body, and then hers, and with a smile on her face, she created 100s of Shadow Clones that started to practice Natural Energy Control, while she again created 10 Shadow Clones that started to find the perfect ratio for Sage Mode Transformation.

...

Hiroto arrived in his laboratory and then took out a few books. He gave these books to Kaguya and said, "Before this, remember everything that is written in these books. I will need your help when you are done reading them."

Two Days later, Kaguya has finished the books and she appeared at his side and said, "I am done."

"Then, let's start the process," Hiroto said as he took out a rabbit and a capsule.

"Try changing the gene in the body and make this rabbit warm-blooded."

Kaguya nodded and then she opened her Byakugan. She put her hand on the body and checked the genes in's cells and then found the gene responsible for making the rabbit cold-blooded. She then remembered the sequence of the gene which is responsible for being warm-blooded and then started to change the genetic sequence in the rabbit's body.

A few minutes later, Kaguya closed her Byakugan and said, "If I were to change only genetic makeup related to cold-blooded and warm-blooded, it wouldn't work and this rabbit would have died. So, I had to change many genes in the rabbit's body."

"What all changes have you made?" Hiroto asked with a curious expression. Even though he knew that rabbit would die, he wanted to know if Kaguya can change and modify genes safely.

"Metabolic Rate, thermoregulation mechanisms, and other stuff."

She said and then created an Ice dome around the rabbit.

"Bring another rabbit and see if it can survive in this environment."

Hiroto nodded and then brought the same type of rabbit and put it in the dome. The rabbit he bought started to shiver, while the rabbit that had been genetically engineered acted as if nothing happened.

Kaguya started to decrease the temperature and the rabbit that Hiroto brought later died when the temperature reached 3 degrees Celcius, and the genetically engineered rabbit could even survive -20 degrees.

"I didn't expect you to succeed on your first attempt."

'This isn't my first attempt.'

Kaguya thought but she didn't say this instead, she said, "I will disperse and let the original know about this. It would be better if you asked the original's help for this case."

Saying this, Kaguya dispersed herself, and seeing this, Hiroto teleported himself to Kaguya's place.

He saw her sitting in the place with her eyes closed and just like here, he counted 50 More Shadow Clones sitting in the place, each having One Tail Worth of chakra.

'What a monster she is. But this also shows that only having a lot of chakras wouldn't make you the strongest. All of them are in Sage Mode. I should have expected this considering her chakra is more than Nine Tails Naruto.'

A few minutes later, all the clones in the place disappeared and Kaguya opened her eyes and she looked at Hiroto.

"Where did you send the clones?"

"In my dimension."

"Don't tell me you plan to use them as batteries?"

Kaguya nodded at this, making Hiroto sigh. He also went to Sage Mode and found that she only has Senjutsu Chakra in her body.

"Let's go, I don't have time to waste," Kaguya said as she opened a portal. Seeing this, Hiroto nodded at her, and he went into the portal with her.
