Ryuu kept Sayuri in his arms, and started talking to Tsunade about the war.
The peace that came after the first ninja war widened the economic gap between countries. The economic and commercial competition between countries increased to share influence across the world and control markets. Countries used "increasing the fairness" as an excuse and the supporting force for the war emerged and gained momentum. Then all countries officially implemented the use of force to expand their territories.
The three major countries participating in the war decided that the fighting would be in the Rain Country to reduce the losses that might occur to their countries.
Rain Country is located in the middle of the ninja world, it is a small but important area because it shares its borders with three countries which are fire, earth and wind.
"I was ordered to go to the front line on the battlefield, Suna's main army seems to have entered the war, and Chiyo seems to have made a new poison which is a very powerful poison," Tsunade said seriously, she had to go to the front line to examine the poisoned people and try to find An antidote to the poison that Chiyo made.
Ryuu nodded, with Tsunade's medicinal skills, she would be able to find the antidote to the poison Chiyo had created.
"I will go alone to the front line, I am afraid that you will be assigned missions during this time, so be careful. Ryuu take good care of Kushina and Mikoto. At your age, you will be given espionage and intelligence missions and deliver war supplies to the front line," Tsunade said while She looks at Ryuu seriously.
"Don't worry, I will take good care of them." Although Kushina and Mikoto are strong and can protect themselves already, he will protect them and not make them endangered.
Also, Kushina and Mikoto each have the strength to participate in the battlefield already, and they are stronger than the majority of the Chunin, and their strength is close to a special Jonin.
"When are you going to the battlefield?" Ryuu asked curiously, he really wanted to go with Tsunade to the front lines to participate in the fight but he couldn't disobey orders to carry out his desires to fight.
"I will go now, you will be the leader in my absence," Tsunade said, then quickly went to the entrance to Konoha Village, some Chunin, Junin, and Medical-nin waiting for her there, ready to go to the front line.
Mikoto spoke after Tsunade left, "We have already got our mission, our mission is to explore the border of the fire country, and we have to tell the village if we find enemies on the border, and if they are few and we can capture or kill them, we will do that and send a report to the village what we have done and We tell them the information we get from the enemies."
"Since we have received the mission, let's get ready. Let's prepare the necessary ninja tools, food and water." After Ryuu gave the order, everyone dispersed and started getting ready.
...
After they got ready, they gathered in front of the entrance to Konoha village, then Ryuu led the team towards the fire country border.
Ryuu and the girls have been searching and exploring the frontiers of fire country for a week, but they haven't found any enemy in this period.
"The mission period is over, we have to go back and report the mission to the Hokage's office." Ryuu gave orders to return to Konoha.
After five minutes of moving in the direction of Konoha, he sensed that there were 5 people 20 km away.
"I found 5 people and from the amount of chakra in their bodies I think they are 3 Chunin and 2 Genin." Ryuu said while pointing to the direction in which the potential enemies are.
The four of them moved towards the enemies quickly, Ryuu spoke while moving, "Me and Sayuri will not fight, Kushina and Mikoto will fight them alone, don't kill them either. We will capture them to extract information from them, if one of you is endangered, I will intervene and defeat the enemies myself."
Kushina and Mikoto nodded in agreement with Ryuu's decision, Sayuri was not interested in fighting weak people so she agreed with Ryuu's decision.
When they arrived at the enemy's location, they saw 3 Chunin and 2 Genin and recognized them from their clothes as being from Suna Village.
'They don't seem to have someone who possesses the sensing skill. So Kushina and Mikoto will make a sneak attack.' Ryuu used sign language to give orders.
Kushina and Mikoto carried out Ryuu's orders and cautiously approached the five people and took out eight shurikens each and quietly and quickly threw them at the five people.
The three chunin noticed the attack early so they could easily dodge the shuriken and one of the two Genin barely evaded the shuriken, but Mikoto appeared in front of him and slashed his neck using the kunai, and the last Genin hit his leg with three shurikens and fell to the ground and Kushina stabbed the kunai in the heart.
Kushina used to kill after many bandit extermination missions, so she didn't feel nauseous or vomit when she killed the Genin.
Kushina and Mikoto chose to kill the Genin in a stealth attack and not the Chunin, because they noticed that the Chunin noticed their sneak attack early on and it became difficult to kill them in a stealth attack, so instead of failing the stealth attack and fighting against 5 people, it's better to reduce their number.
