I'm doing scientific research in the Ninja World

The Heaven and Earth Curse Seal does not appear where it is injected.

Otherwise, Kimimaro's was in the middle of his chest. Could Orochimaru have hit him in the chest?

The location of the seal can be controlled. Theoretically, it can be placed anywhere you want, but Orochimaru still created a three-magatama totem on Red Bean's neck as in the original book.

After seeing Red Bean faint, Orochimaru hurried forward to check her physical condition.

"Huh? Why is your body so hot?"

As soon as he touched her skin, Orochimaru felt the heat radiating from her body.

This was also the first time he used the Heaven and Earth Curse Seal on someone else, and he had no clinical experience in this area.

However, Orochimaru still knew medical ninjutsu. Although he was not as advanced as Tsunade, general treatment was enough.

He checked Red Bean's heart rate and breathing and found nothing unusual. It was only when he touched her forehead that he was sure that this girl had a fever.

And from this situation, it was different from an ordinary fever. The body temperature was much higher.

Carry Hongdou to the single bed in the laboratory, first physically cool her down, and then use a series of medical equipment to measure heart rate and brain fluctuations.

"In addition to the higher body temperature, the activity of cells has also increased!"

After a while, looking at the experimental data just recorded, this is the result of the analysis of Hongdou's blood sample just collected.

Putting down the experimental report in his hand, Orochimaru took a sheet to cover Hongdou. At this time, Hongdou's breathing has stabilized and her body temperature has almost returned to normal.

The next morning, Hongdou slowly opened her eyes.

Because they were in the basement and the environment was a bit dark, Orochimaru only turned on a slightly soft light.

"You're awake! How do you feel?"

Before Hongdou could see the surrounding situation clearly, Orochimaru's voice rang in her ears.

Hongdou turned her head and saw the digital figure sitting by the bed. Orochimaru was gently stroking her forehead.

"Teacher, what's wrong with me?"

Seeing her confused eyes, Orochimaru did not hide it and told her about the Heaven and Earth Curse Seal, otherwise he was afraid that this little girl would have wild thoughts.

After listening to Orochimaru's narration, the doubts in Hongdou's eyes gradually faded, and the fear deep in her eyes slowly dissipated.

"I said I would give you a surprise, but if I told you in advance, it would not be a surprise. You won't blame the teacher, right?"

Orochimaru comforted Honglian in a gentle tone, and told her the cause and effect.

"No, it's just a little too sudden. Hongdou believes that the teacher has a reason to do this!"

Still innocent as always, a few words made Hongdou relieved.

Maybe Hongdou's body was too weak, or the Earth Curse Seal of the Uzumaki clan was too overbearing.

For the next three days, Hongdou spent time lying in bed. Orochimaru did not go to the Root Laboratory, but kept doing experiments in his own laboratory and taking care of Hongdou.

"How do you feel?"

On this day, Orochimaru came to the underground laboratory as usual. At this time, Red Bean had returned to normal and was stretching her legs and loosening her muscles.

"Well! It's fine now, and I feel that my body now has endless power, and my chakra has increased a lot!"

Red Bean said to Orochimaru excitedly, her face flushed with excitement.

You should know that the chakra of ninjas is mostly innate, and it is very difficult to improve it through acquired training.

This is also the reason why many elite ninjas are very careful in calculations, saving chakra and using one point as two points.

The best among them are Uchiha Itachi and Kakashi. The two have little mana, but they can exert powerful strength.

"I didn't expect that the Earth Curse Seal would have such an effect even when it is not unlocked!"

The cells of the Uzumaki clan radiate a little bit and bring a considerable improvement to the host. It seems that the effect of this curse seal is not bad!

Seeing that Hongdou was in high spirits, Orochimaru simply observed the effect of the Earth Seal further.

"Release the power of the seal and show me."

After receiving the order from Orochimaru, Hongdou did not hesitate. She had been eager to try.

When she recovered, she felt that there seemed to be a powerful force sealed at her neck.

But this power was a bit violent, and she didn't dare to use it easily without Orochimaru by her side.

Now with Orochimaru's permission, she naturally no longer hesitated.

The next moment, the three magatama totems on Hongdou's neck gradually dispersed, and then two black totems appeared under the corners of her eyes.

It was a bit like the red mark on Jiraiya's face, but more like Orochimaru's appearance in Sage Mode.

Her eyes graduallyThe snake eyes transformed into Orochimaru's, and it was more obvious that the black hair had turned red at this time, just like the Uzumaki clan.

"Ahh...!"

As Red Bean released the curse seal, a violent and powerful chakra emanated from her body.

The airflow generated also blew the surrounding experimental equipment and the glass test tubes jingled.

"Such chakra strength is already catching up with most of the jonin!"

Seeing Red Bean's changes, Orochimaru's eyes became brighter and brighter, as if appreciating a brand new work of art.

In the original work, Red Bean did not use the curse seal, but Orochimaru thought that it must be different from the scene in front of him.

The power of the curse seal, like the Eight Gates of Ninjutsu, can be improved according to personal strength. In the case of opening the same death gate, Might Guy is not as good as Might Guy.

Such an increase is determined according to the growth of the host. The stronger the host, the stronger the curse seal is amplified, and the stronger the strength that can be exerted is naturally.

A knife has different effects in the hands of a child and an adult.

But before Orochimaru could observe for a while, Hongdou collapsed to the ground, and the changes on her body quickly returned to normal.

"Huff... Teacher... I...!"

Orochimaru hurried forward to check her condition, and found that she was just a little weak before he felt relieved.

"The power of the curse seal is too violent, I... can't control it."

Hongdou kept panting, and her little face was covered with sweat in just a short while, and her hands and feet were shaking slightly uncontrollably.

It seems that while the curse seal brings her power, it will also put a greater burden on her body, and it is not without cost.

"You have done very well. It is inevitable that you will feel uncomfortable when using it for the first time. Strengthen your training in the future. The teacher believes that you can master it!"

Rather than blaming her for being so unpromising, Orochimaru gently rubbed her little head. After all, not everyone is a second-rate person, and you can't be too strict.

"Yes!! I will never let the teacher down!"

After receiving the comfort and encouragement from Orochimaru, the shame and disappointment in Red Bean's eyes disappeared, and she developed a fighting spirit that would never give up.

Orochimaru liked her obedient, stubborn and unyielding look.
