As the sun sets, the dusk light illuminates the land, and groups of ninjas pour into Konoha Village.

Back in Konoha, Song Jing didn't have to carry out the escort mission, and rushed to Orochimaru's side under the Moo's Gate.

"Orochimaru-sama"

The troops and the wounded marched slowly, and Orochimaru stood on the side of the road, looking at the Hokage statues in the distance, and with the magnificent sunset, the beauty of the scenery was refreshing.

In Song Jing's words, he came back to his senses, jumped on the roof of the house, and said: "Go to the root to report, and by the way, engrave the curse mark of the root of the tongue."

Song Jing followed, and the Uchiha returned to the place where the Uchiha clan greeted him, and it seemed that he didn't need to act with Song Jing anymore, he was only arranged by Orochimaru's side during the war, and he was not a member of the Dark and Root Divisions.

During the leap, I often saw the soldiers and their relatives and friends crying together on the way below, crying with joy, and then looking at the back of the continuous jumping in front of me, there seemed to be a trace of loneliness that was not easy to detect.

After a short time, Orochimaru came to a small building in the middle of nowhere, where a secret door opened on the first floor, and a long black staircase appeared leading to the ground, and in the dim light, the two walked in.

Along the way, there was silence, only the rhythmic footsteps echoed.

Walking down the stairs and through the long tunnel, Orochimaru led Song Jing to an empty space underneath.

It was brightly lit, with towering buildings and pipes leading in all directions, and from time to time black-clad members of the Roots hurried by, some unarmed, not like they were on a mission, and it looked like a small settlement, except that there were no bells and whistles in the village above.

Orochimaru led Song Jing into the tallest building among them, and walked straight forward, without stopping, and the layers of guards did not stop them, so that the two of them could be unimpeded, it seems that Orochimaru has long been in the same stream as Tuan Zang.

Arriving at a Japanese-style lounge, an old man with a bandage on his head and wearing a kimono was already waiting here, it was Danzo, but not as old as he was later, and two guards stood upright next to him.

"Orochimaru"

Tuan Zang said in a low voice, holding up the eyes of the gloomy owl, which is really synonymous with the darkness of Konoha.

Orochimaru was not in a very good mood, and said succinctly: "Don't talk nonsense, let's start"

With a cold gaze scanning from top to bottom, Song Jing calmly crossed the Great Snake Pill and stepped forward.

"Yes, yes, it's good."

Tuan Zang nodded, his calm posture and calm psychological quality, in a way, it is very suitable to act in the dark and do dirty things for Konoha.

Seeing that Song Jing was wearing a tight black mask, he said calmly: "Take it off"

Although Song Jing really wanted to control a soul to receive the curse mark of the tongue curse for him, doing so would be accompanied by a change in his appearance, which would definitely be noticed by Orochimaru, who had known his face for a long time.

So, he can only show his true face, anyway, the curse mark of the tongue only restricts him from divulging information, and the impact on his behavior is not great, and he doesn't want the immortal spell mark developed by Orochimaru in the future.

The inscription of the curse seal of the root of the tongue went very well, and after the incident, Song Jing had an extra gossip-style pattern on his tongue, and if he wanted to tell the information about Tuanzang and Orochimaru, his body immediately stiffened and he couldn't help himself.

Song Jing was only one of Konoha's own people at this time, and Orochimaru and Tuan Zangping withdrew from everyone and began a secret negotiation.

Although I don't know what they said, it is easy to conclude from the original book that most of them are taboo studies about Orochimaru, and they are all shady things.

After half a day, Orochimaru walked out of the room, took Song Jing to the tunnel outside, and after seven bends and eight turns, he came to the area of a research institute, of course, on the way, there were researchers in white trench coats, all of whom respectfully greeted Orochimaru.

Coming to one of the rest rooms, Orochimaru sat down and said to Song Jing: "Since Wujun wants to cure the bloodline disease as soon as possible, let's be my assistant first, and studying the secrets of the bloodline is not achieved overnight."

Luckily, a few clones were released early, otherwise I don't know how long I would have been trapped here... Song Jing secretly said that they were all shortcomings of insufficient strength, so if he wanted to obtain the technology of the Great Snake Pill, he would inevitably have such a result.

Song Jing nodded calmly and said, "I am willing to serve the adult..."

"Then take another sample of your blood..."

..........

"Is the curse of the tongue cursed?"

The water country clone stroked his tongue, there was a rune that was the same as the main body, it seemed that this spell was a soul-level ability, and it couldn't be cheated with the dead river clone.

Outside, there was a sudden sound of fierce swordsmanship.

Song Jing opened the Japanese-style partition door, opened the door, and looked outside, and found that the thick fog had crept in, and the naked eye could only barely see the things one or two steps in front of him.

The remnants of the light simply can't penetrate such a thick fog, and if you take a few steps outside the house, you will lose your reference, and you will feel that you are alone in the world, and when the night falls, it will be even more terrifying.

Song Jing quickly picked up the katana, jumped on the roof, listened to the source of the sound, and soon touched the place of the battle, which was the main entrance of the mansion.

Through the open door, Song Jing saw that the old man Komai Youichi was cleaning up a corpse, which was also a middle-aged man who used a katana, but there were many patches on his clothes, it could be seen that this person's life may be relatively poor, and the ground was covered with messy footprints, and it seemed that the battle had just ended.

"Make your guests smile"

Komai's wrinkled face showed a little apology, but he didn't stop in his hand, pushed the body aside, put away the enemy's katana, and placed it on the wall of the doorway.

"This is..."

Song Jing thought that the fog ninja he had assassinated before was coming, but he didn't expect the battle to end so early.

Komai skillfully closed the gate, shook his head and explained:

"This is the blood mist, like such a thick fog, even the noon sun can't penetrate it, and the figure disappears after two steps, and it's easy to escape if you do bad things, unless you look at your face, you can't see your face clearly, so there are many fights at this time."

"Yesterday it rained heavily, the water vapor was abundant, this time the blood mist may last all night, guests go to rest, I'll keep vigil, although I'm old, but this bit of skill is still there, with the prestige of Komai New Yin Stream, most people will avoid here"

"Is that so?"

Maybe ordinary people will have trouble sleeping in this situation, but Song Jing's eyes lit up, since everyone is a hunter, then everyone is also a prey, which is just used to practice swordsmanship, and it can also kill two birds with one stone, by the way, harvest the souls of the wicked, and then accelerate the understanding of swordsmanship.

"Then let me also appreciate the prestige of the Blood Mist."

"Is that so? It's too dangerous, and there's a mist ninja lurking inside..."

Komai Youichi was slightly stunned when he heard this, practicing swordsmanship in the blood mist is indeed a good strategy, someone has done this a long time ago, but the risk is too great. No one knows how many people will be attracted by this, whether someone will take the opportunity to sneak attack, and most of those who tried it will not even find their bodies.

"Don't worry"

Song Jing smiled leisurely, stepped on his right foot, and his figure floated over the wall of the mansion and disappeared under the worried gaze of the old man.
