I'm doing scientific research in the Ninja World

"Duan, hold on a little longer, I will heal you..."

In the rainy forest, several ninjas were surrounding a seriously injured and dying person without saying a word. The only sound was the woman's pleading.

Her hands were still constantly supplying chakra to the ninja in front of her, but the ninja named 'Duan' was breathing in more than out.

"No... You promised me..."

The woman's pleading voice was trembling, and her face was already covered with tears, but she was washed over and over by the rain, and she looked like a drowned chicken, looking very embarrassed.

The companions around her wanted to speak but stopped, which made the atmosphere seem extremely depressing.

This scene was seen by a young man standing on a tree not far away.

The young man had long black hair and a pair of cold snake eyes, but when he saw the crying woman in front of him, a trace of pity flashed in his eyes.

The young man was Orochimaru, and the only woman who could make him show such an expression was Tsunade Senju, who was also one of the three ninjas.

Not long ago, Chiyo, a ninja from the Hidden Sand Village, personally led a group of elite ninjas from the Hidden Sand Village to attack Konoha. Kato Dan, who was in charge of patrolling, led the ninja team to block the attack.

Tsunade, who had just returned from a mission in the Rain Country not long ago, was among them. The two of them were like newlyweds after a long separation, and they were also very close during this period.

Chiyo and Tsunade staged a duel of medical ninjutsu, while Kato Dan relied on the bug-level spiritual transformation technique to kill all on the battlefield.

At the beginning, no one could stop him, but the elite ninjas of the Hidden Sand Village were not vegetarians. After Kato Dan harvested more than 20 companions, the Hidden Sand Village ninjas still seized the opportunity and gave his body a fierce wave.

Two fists cannot beat four hands. Facing the situation of being outnumbered, Kato Dan lost sight of one thing and another, and a negligence made him doomed.

When Orochimaru, who had rushed to the battlefield after hearing the news, arrived at the battlefield, Kato Dan was already dying.

"Tangible things will be destroyed sooner or later, but intangible things will be eternal."

Even though he was used to seeing life and death on the battlefield, Orochimaru, who was known for his cold and decisive killing, could not remain calm when facing a battle with someone he knew well.

Kato Dan was Tsunade's lover, but also a companion he knew. Looking at Kato Dan, who had already lost his breath, and then looking at Tsunade, who was crying in fear.

Perhaps he could not bear such a depressing environment, Orochimaru exerted force on his feet and disappeared in the next moment.

The ninjas of the Sand Village had already fled in all directions. Chiyo was slightly inferior to Tsunade in the fight, and did not get any benefits. At this time, he was fleeing the battlefield with the few remaining ninjas.

"Master Chiyo, we suffered heavy losses in this raid. Are we just going to let it go?"

A ninja who was covering his wound said to Chiyo. From his weak tone, it can be heard that he was also seriously injured.

"We still underestimated Konoha's strength. This action was a bit hasty. I didn't expect Konoha to react so quickly. I underestimated the time they would return from the Rain Country."

Chiyo, who was moving quickly towards the outskirts of the Fire Country in the rainy night, said in a somewhat unbearable tone.

Originally, they wanted to take the opportunity to sneak attack Konoha when most of Konoha's elite ninjas attacked the Rain Country.

There was nothing wrong with their plan. The Sand Village took the lead in sending Chiyo's son and daughter-in-law, who were the parents of the Red Sand Scorpion.

But what they didn't expect was that there was a war god, Konoha White Fang, in the unprecedentedly empty Konoha.

The two came over aggressively and were chopped down by Hatake Sakumo one by one.

This wave of thousands of miles of sending heads made White Fang famous for a while, not inferior to the newly famous three ninjas.

This is why the Sand Village's action this time can be said to be completely for revenge.

"Although we lost a lot of companions, we also killed that tricky guy in Konoha. It is said that he is Tsunade's lover."

Thinking of Kato Dan's spiritual transformation technique, the ninja's eyes were still full of fear, but his tone was very relieved and gloating.

"Speed ​​up, Konoha's ninjas have caught up."

While speaking, Chiyo set up a few simple detonating talisman traps along the way, not asking for much damage to the pursuers, just hoping to stop the pursuers' steps and buy them more time.

After a while, a ninja with wet long hair came to the trap set by Chiyo and others just now.

As soon as the footsteps fell, crackling explosions sounded all over his body, drowning him in an instant.

The fire that suddenly lit up in the rainy night illuminated the surrounding forest, and the other tracking Konoha ninjas also looked over here.

After the thick smoke, a pair of cold snake eyes came into view.

"Ninjas from the Sand Village, you really deserveDie!"

It was Orochimaru who caught up with them. He was looking ahead with cold eyes and licking his lips involuntarily.

Seeing that it was Orochimaru, the other Konoha ninjas were relieved. They could easily deal with such attacks, not to mention the already famous Orochimaru.

Just when Orochimaru was about to continue chasing, he suddenly felt a sharp pain in his head, which made him stop his steps.

The next moment, Orochimaru fell from the tree. In the dark night, he did not attract the attention of other ninjas, and the sound of heavy rain even covered the sound of landing.

The next day, Konoha Hospital.

Orochimaru slowly opened his eyes, and the morning sun shone on his face through the window, making his pale face look a little sick.

"Where am I? "

Before he could fully open his confused eyes, a series of memories filled his mind, causing him to lie down powerlessly again.

It was unknown how long it took before Orochimaru opened his eyes again, but there was still confusion and disbelief in his eyes.

He was originally a scientific researcher in the 21st century. When he was out collecting materials, he was accidentally bitten by a small white snake. He died before his colleagues could send him to the hospital.

When he woke up again, he was in the hospital, but it was not the hospital in his original world.

Through the memory of the original owner, he knew the identity of the original owner of this body and the world he belonged to.

Sitting up from the bed, Orochimaru carefully looked at his outfit, and pinched his arm hard. The pain made him realize that all this was not a dream.

"I didn't expect that I would travel through time one day, and I traveled to this body after being bitten by a snake. "

Orochimaru sighed to the sky. Others who traveled through time were either from the Uchiha and Hyuga families who had bloodline limits, or from the Senju Uzumaki clan who had immortal bodies.

Although Orochimaru was not bad, in this ninja world where bloodline was the most important, his upper limit was not as good as these chosen ones.
