Because the war between Kumogakure and Konoha ended too fast, the other countries didn't know what happened.
In order to figure out the truth, spies from various countries marched into Konoha at the speed of light.
Konoha naturally would not sit still. They sent a large number of Shinobi to defend the border, and at the same time, Anbu was sent to capture spies from.
Due to the separation of the training team and Anbu, the Fourth Hokage Anbu lost a lot of people and did not have enough manpower. Therefore, Nagasawa sent the Fourth Team that was led by Shisui to assist Anbu.
Then, Shisui led the Fourth Team to join the Anbu's operation to eliminate the spies from neighboring countries, with him as the Vice-Leader.
"Leader Shisui, three members of Anbu disappeared in Starfall Valley. They have not been in contact for more than two days." The intel officer reported the latest information to Shisui.
"It has already been more than two days..." Shisui frowned slightly. There were three only a total of four Anbu members, with three of them missing.
"You go down first. I will go find the village leader." Shisui said after thinking for a while.
Nakamura Hiko was the captain of the Fourth Hokage Anbu's new second team. At the same time, he was also the leader of this operation. He was a veteran Anbu member.
After reading the intel, Shisui went to Nakamura Hiko.
Shisui quickly told Nakamura Hiko the intelligence and said, "This is a bit unusual. I want to bring someone with me to investigate this personally."
"For three Anbu to go missing without even being able to pass a message at the same time is truly a bit strange." Nakamura Hiko nodded with a solemn expression.
Anbu members were not stubborn. If they knew they could not win, they would immediately think of a way to escape. If they could not escape, they would at least think of a way to pass the information.
"Then I'll have to trouble you, Shisui-kun."
Although the young man in front of him was very young, just like an Academy student who had just graduated two years ago, Nakamura did not look down on him.
The training team and the Fourth Hokage Anbu wore different type of pants, and they acknowledged each other.
For example, they clearly knew how strong the First Team's leader, Kakashi, who subdued the Two-Tails Jinchuriki in the battlefield was.
Although the Second and Third Team Leader was not as strong as Kakashi, they were both elites among Jonin.
As for the Fourth Team's, Uchiha Shisui, rumor said that Shisui and Kakashi were about the same level.
He did not know if Shisui could beat a Jinchuriki, but he was certainly stronger than Nakamura.
"It is my duty, so it's no trouble, really." Shisui said with a smile.
After discussing with Nakamura Hiko, Shisui quickly summoned the two members of the Fourth Team.
One of them was his fellow clansman, Rai Uchiha, while the other was a member of his team that he looked up to. His name was Yoshino Hisashi. He was pretty good in Six Powers and he was level-headed.
Shisui briefly explained the situation to the two of them and quickly brought the two of them to the Falling Star Valley in the south of Land of Fire.
"According to the information, Starfall Valley had existed for a very long time. It was a huge crater that was created by the falling star, or rather meteorite. The information did not mention how when it was created specifically. Other than this record, there was very little information about it. Some were only records of the past hundred years. It was said that there were a large number of poisonous beasts and insects used to dwell in this place. Moreover, there was a strange magnetic field that prevented any electronic equipment from fucntioning there. It was a forbidden area for humans... "
On the way, Shisui and his two teammates talked about the information he had found about Starfall Valley.
Although poisonous beasts and insects were dangerous for ordinary people, they should be nothing to Shinobi, let alone the Anbu elites like them.
"I think that this disappearance is more likely to be related to the other major countries. Land of Water, in particular, is suspicious. Rai Uchiha analyzed.
Land of Fire was more developed in the north and middle region, and it was also the most populated place, while the south was a remote countryside, with very little population.
The reason why Rai Uchiha was said that Land of Water was very suspicious was because Land of Water attacked Land of Fire's east coast on a large scale during the Third Shinobi World War.
Land of Water's force could easily enter through the south coast or east coast.
If there was a problem in south of Land of Fire, the most suspicious one would be Land of Water.
"I agree. Among the four major powers, Land of Water is the most suspicious," Yoshino Hisashi said.
"That's why I brought both of you along. If Land of Water had some sort of plan in Starfall Valley, we must prevent it." Shisui noded.
Shisui was glad that his team members were not the type of reckless people with insufficient strength to back if off because there were also some Uchiha who were capable of rational thinking.
If Shisui's predecessors could think more rationally before acting, then the relationship between Uchiha Clan and the village would not be this bad.
If it was just an accident, and the three Anbu were fine, then it was naturally good, but if it were a problem left behind by the Third Shinobi World War, then they would have to deal with it.
It only took two days for them to arrive at Starfall Valley.
Shisui looked at the Starfall Valley. The terrain of the Starfall Valley was very different from the description. There were two slopes on the left and right, and the middle was sunken. The closer they got to the middle, the lower the ground was. In the middle, there was also a strange looking small slope that connected the three slopes together and surrounded the whole Starfall Valley.
"We will enter the Starfall Valley immediately. Be careful!" Shisui reminded.
For some reason, he had a vague feeling that this place was bad news.
However, Shisui did not think too much about it. He just thought that he wasn't feeling well today.
"Don't worry, Team Leader Shisui. We're 100% serious," Rai Uchiha said. Then, he took out a gas mask and put it on.
Yoshino Hisashi nodded and also wore a gas mask.
Because it was a desolate and uninhabited place with a large number of poisonous insects and beasts, Shisui was afraid that there would be harmful substance around here, so he asked them all to wear gas masks.
Shisui also put on the gas mask as he took the lead.
...
Suddenly, a blue light flashed in such a dark and silent place.
"Beep... two dangerous breather carriers detected... requesting retreat..."
"Flight System is not responding... Requesting repair... Automatic repair system is not responding... "
"Beep... Retreat failed... Requesting permission to launch a long-range attack... Weapon System is not responding..."
The dark control room suddenly turned red.
Finally, amidst the ruckus, a stone covered in green moss on the small slope in the middle actually opened like a door.
