I'm doing scientific research in the Ninja World

Outside, at the border of the Land of Earth and the Land of Waterfall.

A middle-aged man who looked like a monk was meditating and practicing in the jungle.

The monk had red hair tied into a ponytail, a red beard, a black protective gear on the bridge of his nose, and a purple robe and chest armor that were even more conspicuous.

This man was Lao Zi, the rebel ninja from the Hidden Rock Village, and also the Jinchūriki of the Four-tailed Son Goku.

"Lao Zi, it's not easy to defect, right? Look at what you can do!"

In the spiritual world, Sun Wukong said to Lao Zi gloatingly that after Lao Zi's hard practice over the years, the relationship between the man and the beast has been eased.

Sun Wukong now has a preliminary recognition of Lao Zi as his host. The only thing that makes him feel comfortable is that this guy can do anything else but become a monk.

This is a torment for him with a bad temper. If there are frequent fights, it's okay, but fighting and killing is unlikely for a monk.

There are gains and losses, but it is precisely because of Lao Zi's peaceful mentality that it can be recognized by it.

"At midnight, the turbid wine comforts the loneliness, and at dawn, I ride into the world; the world tempers the heart, and the experience awakens the soul!"

Lao Zi turned a deaf ear to Sun Wukong's ridicule. I don't know how many times he has said such words, but the stubborn Lao Zi is also unmoved.

"Humph! It's so boring!"

Seeing that Lao Zi ignored it, it simply stopped talking. Every day, apart from traveling around, it practiced the two people's coordinated ninjutsu. Lao Zi was also very competitive in this regard. Except for resting on the road, the rest of the time was spent practicing hard to control the four-tailed beast.

Now the two have some tacit understanding, but there is still a long way to go before the perfect Jinchūriki.

Lao Zi saw that Sun Wukong was no longer making trouble. It was time to rest after a tiring day. He had to go on the road tomorrow.

In the Longdi Cave, on the altar.

After three days of meditation, he had initially adapted to the domineering characteristics of natural energy.

The chakra of the body also balanced the invasion of natural energy, and the snake transformation of the appearance no longer continued, but two black tear marks appeared under his eyes at some point.

Black is one of the signs of immortalization, but in Orochimaru's impression, only the immortal modes of Wet Bone Forest and Myoboku Mountain have such tattoos, and Ryuchi Cave is no exception.

Orochimaru naturally didn't know about the changes in his appearance, but he felt that his body had gradually returned to normal. Now all he had to do was to completely control this energy and use it for himself.

Half a month later, Orochimaru slowly opened his eyes and couldn't help but spit out a foul breath from his mouth.

"Congratulations on your entry into immortal arts!"

The first time Orochimaru opened his eyes, a soft female voice sounded in his ears. He looked up and saw that it was Ichikishimahime.

"Just the initial entry?"

Orochimaru stood up from the altar. After meditating for half a month, his body became stiff, but what made him feel amazing was that after not eating for such a long time, his body did not send out hunger signals.

With his powerful immortal body, it was completely within his expectation that he could learn immortal arts. What surprised him was that the natural energy injected by the White Snake Immortal could actually maintain his vitality for so long.

"Of course, this is just the first step. There is still a long way to go!"

Ichikishima said slowly, and then motioned Orochimaru to follow her.

Orochimaru had nothing to hesitate about. It was normal for people to learn immortal arts for three to five months, or as long as a year and a half. He didn't think he had learned it in just half a month.

Although he claimed to be a genius, he didn't achieve such a great ability after learning it, unless... the system rewarded him!

Following Ichikishima, he walked deep into the ground. After a while, a burst of light came from the front of the passage.

"Huh? Where is this?"

He blocked the dazzling light a little. He was not used to the strong light after staying in the dim cave for too long.

Before he could fully adapt to the scene in front of him, he heard the sound of insects and birds, and the air was filled with the fragrance of flowers and plants.

When he saw the scene clearly, he was even more shocked. He saw birds singing and flowers blooming, and the beautiful mountains and rivers were like a veritable paradise!

I just don't know what the light source here is, I think it must be a fairy's trick.

"It seems that this is the real fairy holy land, right?"

Seeing Orochimaru's inexperienced look, Ichikishimaji smiled sweetly.

"This underground world is not for everyone. There are only a handful of humans who have come here in the past thousand years!"

Hearing her words, Orochimaru realized that the air here was filled with a lot of natural energy, not much less than the habitat of the White Snake Fairy.

"Gurgle..."

It was also at this time that Orochimaru's stomach started to rumble unconsciously, and hunger surgedTo the heart.

"Hehe... you can find a way to solve your problem yourself!"

Looking at Orochimaru's somewhat embarrassed face, Ichikishimahime covered her mouth and chuckled, and floated away without telling Orochimaru how to solve the food problem.

Orochimaru could only walk forward helplessly. The environment here is good, and the food chain should be mature. It's impossible to eat insects all day long like in Myoboku Mountain, right?

It just so happens that there is no food here, and I have more autonomy. There should be no problem except not eating their disciples and grandchildren, right?

Thinking of this, Orochimaru walked towards the tall bushes and appreciated the scenery here by the way.

Not long after, Orochimaru started to heat oil in a pan. Next to him was a big fish that had been cleaned. It should be more than ten pounds.

It must be said that in this environment, not only is there sufficient natural energy, but the oxygen content in the air is also thicker than that in the outside world, which also makes the creatures here much larger than those in the outside world.

Isn't it basic to bring pots and pans when traveling at home? And it was just a matter of a scroll of ninja tools, no problem.

As Orochimaru cooked, the aroma of food spread, and soon attracted many animals to watch.

However, these animals only dared to watch from afar, and they dared not go forward but were reluctant to leave.

"Get out of the way, a group of ants!"

With a roar, a huge monster appeared in front of Orochimaru, which was the healed Manabu.

It also came here by smelling the smell, as for the arrogant guy Xinya, it was probably unable to bear the blow of failure and became autistic.

"Orochimaru! You are so brave, you dare to trespass into the holy land!"

Manabu looked down at Orochimaru, but the drool dripping from its mouth betrayed its thoughts at the moment.

Orochimaru didn't believe that this guy didn't know why he came here, and who could come here without the permission of the White Snake Immortal!

As for putting the blame on itself right away, you can tell what it is planning by looking at the saliva around its mouth.
