The fortress where Mu Sen was stationed was not very far from the front line, and there were flying eagles specially trained to deliver news, and the news was delivered to the Konoha front camp in less than an hour or two, and they replied just as quickly, and it didn't take half a day to go back and forth.

In the fortress conference room, Mu Sen and the five elite shinobi were all waiting for news, Mu Sen considered that there were some doubts about the attack and killing escort team, so he didn't dare to act at a loss, but let his subordinates strengthen their vigilance near the fortress, and the vigilance was changed from the original two squads to five squads, and the remaining five squads came to change shifts every twelve hours, and even the daily training, Mu Sen canceled.

It didn't take long for a middle ninja to walk in with a scroll, hand the scroll to Mu Sen, and said, "Captain, this is a reply from the front-line command. ”

After Mu Sen took the scroll, he opened it and looked at it, his brows furrowed slightly, and when the others saw this, someone asked, "Captain, what's wrong?" What kind of orders does the front-line command have?"

Mu Sen threw the scroll on the table and said, "See for yourself!" After speaking, a person fell silent, and in the reply letter from the front command, he did not pay too much attention to this matter, thinking that this might just be a few fish left behind by the previous clearance of the fog ninja who infiltrated the Fire Country, and it was completely unsuccessful, so he did not plan to send someone over, only let Mu Sen deal with it himself, and be sure to find the attacker.

Indeed, on the surface, it seems to be the case, but Mu Sen always had a bad premonition in his heart, especially the attacker's handling of the corpse, which made him feel that things were not so simple, if it was really done by the fog ninja, he would definitely dispose of the corpse so as not to expose his traces.

Now he simply covered the corpse, but it was more like he wanted them to find out, wait, want to be discovered? Thinking of this, Mu Sen couldn't help but think of four words in his mind, turning the tiger away from the mountain, this attack seemed to be a game from the beginning.

The location of the attack is near Mu Sen's station, according to the general situation, Mu Sen is responsible for investigating this matter, and if he wants to find out the attacker, then he must mobilize manpower to survey the vicinity, so that the fortress must be empty, and when the enemy takes the opportunity to invade, it seems that it is possible to destroy this Konoha supply base in one fell swoop.

It's just that Mu Sen doesn't understand one thing is that the fortress he is stationed in is just a very ordinary supply base, and the main ones stored are ordinary ninja tools such as shuriken, kunai, etc., if the attacker is a fog ninja, then why would they choose such a supply base that would not have much impact even if it was destroyed?

If you want to know the answer, you only need to plan it, thinking of this, Mu Sen already had some plans in his heart, so he immediately discussed it with the five elite ninjas, although this plan was based on his speculation, but even if it wasn't so, it would have no effect, it was nothing more than a waste of time, and it didn't hurt.

After the plan was formulated, Mu Sen immediately began to deploy manpower, a hundred ninja team, Mu Sen divided it into five pairs, each team was led by an elite ninja as the team leader, leaving a team of twenty ninjas as a fortress, and the other four teams searched in four directions, and when they encountered the enemy, they would launch special signal flares to transmit messages, and other teams nearby would also come to support in time.

Mu Sen's order to them is to search in a carpet way, step by step, not to rush forward, to keep a distance that no team can see at all times, at least to allow a team to see the signal flare, as for Mu Sen, he is a team alone, with his strength of Shangnin plus the Eight Gate Dunjia, unless the shadow-level powerhouse of Wuyin Village sneaks in, otherwise he will not be in much danger, and even if he encounters danger, it is a burden to bring other people by his side, it is better to be alone.

The four search teams are responsible for searching the three directions of southeast, east and west, so that they can also maintain a distance from each other, and Mu Sen is responsible for searching the north direction alone, he can perceive ninjutsu, and the search range is far wider than these four teams.

After preparing everything, Mu Sen and the four teams left the fortress together and leaped in different directions, while the remaining twenty ninjas continued to guard the fortress, and the atmosphere was much more tense than usual.

·······························

Night was slowly falling, in an extremely hidden cave, eight figures were quietly hiding in it, and the mouth of the cave was tightly covered by rattans, only a few traces of bright moonlight leaked in through a little gap, which could vaguely see a little situation inside, these people all had a common sign, that is, the mark on their foreheads was the appearance of four drops of rain.

These people turned out to be misty ninjas, they were the targets that Mu Sen needed to search, and it was they who attacked the Konoha ninja team that escorted the ninjas, and the place where they were hiding was not very far from that fortress.

There was silence in the cave, and only the faint breathing of these people could be heard, and at this time, a person suddenly lifted the obscuring vines and walked in, and the eight fog ninjas inside looked at it together, only to see the man speak: "Everyone, the plan has been successful, they have been selected, and there is..." ”

One of the mist ninjas at the head nodded and said in a deep voice: "Okay, then everything will go according to plan, one hit is incomparably successful, remember, don't fall in love, after the task is completed, retreat according to the predetermined plan." ”

When the eight mist ninjas heard this, they all nodded, and then they left the cave together and started to act, while the mist ninja who was the leader slowly walked out of the cave, and the bright moonlight shone on his face, reflecting a biting chill.

·······························

After leaving the fortress, Mu Sen leaped between the trees while using perceptual ninjutsu to search the surrounding situation, but the speed of his journey was not very fast, and he didn't seem to be in a hurry to find the attacker, but leisurely, before the sun set, he stopped and began to rest in place.

When the moon slowly rose, Mu Sen got up, glanced at the direction he came from, and set off again, but the direction was exactly the opposite of when he came, it was the direction of returning to the fortress base, along the way, Mu Sen did not delay any longer, galloped all the way, in order to rush back to the fortress as soon as possible.

Mu Sen suspected that the attacker's target was likely to be the fortress, so he had already ordered the other four teams to set off and quietly return to the fortress at sunset, although he was not sure that the mist ninja would definitely attack the fortress, but it was always a big mistake to be careful, and even if it was wrong, it was just a waste of time to go back and forth.

It's just that he didn't walk for a while, Mu Sen suddenly stopped, landed on a clearing, looking at the shadows in the dense woods, he shouted coldly: "What person, come out for me!" His face was full of solemnity, the amount of chakra of the person who came was very large, a few points more than him, and his strength was absolutely extraordinary, at least he was also a ninja at the upper ninja level.
