Naruto: The strongest fire style Blade Jakka!

Uchiha Jing continued: "Since your fire escape is so powerful, it may be related to your physique, so you need to develop your physique accordingly, just like my Sharingan. When we develop Sharingan, it is also..."

Following Uchiha Jing's narration, Li Yi had some idea about the development of the Sharingan.

"So, since you have an affinity for fire, you should integrate into the fire and try to experience it. The development of every bloodline is dangerous, and you must be mentally prepared!" Uchiha Kagami said earnestly.

Li Yi nodded. After Uchiha Jing's narration, Li Yi had some idea. Otherwise, he would be really confused about the development of the Flame-Flame Fruit. Just look at the world of pirates. All you have to do is eat it. As for the final form, that's all later. But in the beginning, the most basic applications were all learned by yourself.

But when it comes to himself, Li Yi doesn't want to complain. How should I put it? It's like constipation. The powerful devil fruit was used by himself as a small power bank, which can only increase the power of ninjutsu a little bit. This is a bit hurtful.

In this way, following behind Uchiha Jing, Li Yi was patrolling while also comprehending his fire attribute chakra and some special features of his body.

Gradually, time passed faster and faster, and border frictions became more and more intense. In two years, Li Yi could already complete patrols independently, and even led some Chunin patrols from Konoha. Although it cannot be said that Li Yi is a veteran on the battlefield, he is also familiar with it.

For two years, Li Yi, in addition to refining chakra every day, has been developing his own Flame-Flame Fruit. Because of his targeted approach and grasp of its special features, Li Yi has already mastered some of the power of the Flame-Flame Fruit.

During these two years, Li Yi has more or less understood something. Perhaps it is due to the difference in the rules of the world. The development of the ability of the Flame-Flame Fruit is actually linked to Li Yi's chakra. Now, Li Yi can already partially elementalize his body, and the Fire Style he uses has been enhanced with the ability of the Flame-Flame Fruit, making it even more powerful. Even if Li Yi has not mastered the changes in the nature of chakra, the power of the Fire Style he uses is no weaker than that of the changes in the nature of chakra.

Thinking about it, after traveling to the present, Li Yi finally has a certain amount of self-protection capital. At the very least, his partially elemental body can make him immune to many attacks.

As for Ryujin Jakka, there has been no movement so far. It might be because he had killed too few people. Although he had been on the border for two years, there were not many real battles. Basically, the ninjas on both sides threw some shurikens at each other and then disappeared.

It was only recently that things started to go wrong and things became quite tense.

"Xiao Yi, come with me, we have a new mission!" At this time, Uchiha Jing appeared in front of Li Yi and said directly.

Li Yi followed Uchiha Jing without saying a word.

While running, Li Yi asked, "Teacher, are we going to the border of the Rain Country?"

Uchiha Kagami nodded and said, "Ninjas from the Hidden Mist Village have crossed the border from here many times and attacked the village ninjas. Among them are the most famous Ninja Swordsmen of the Hidden Mist Village. They come and go without a trace. The Third Hokage asked me to go and snipe these Ninja Swordsmen."

Li Yi suddenly realized that they were the Ninja Swordsmen of the Hidden Mist. At that time, they were not yet called the Seven Ninja Swordsmen of the Hidden Mist. After all, there were less than seven people, but they were undoubtedly the high-end combat force of the Hidden Mist Village.

The fact that Konoha sent Uchiha Kagami to carry out the sniper attack was enough to show how much importance they attach to the Hidden Mist Village.

"Xiao Yi, the Ninja Swordsmen are all elite jonin, and their ninja swords are quite powerful. If you encounter them head-on, remember to run away, okay?" Uchiha Jing said at this time.

After all, Li Yi is still a Chunin in name. Of course, with Li Yi's strength, it is completely correct to say that he is a Special Jonin. It's just that he has not yet mastered the changes in the nature of chakra. Once Li Yi masters it, he will be a complete Jonin.

If you just want to become a jonin, you still need Konoha's assessment and the joint recommendation of two jonin, which is very troublesome.

"I understand!" Li Yi said directly.

This time, the reason why Uchiha Jing brought Li Yi with him was because he didn't know when he would encounter the Ninja Swordsmen, but he would definitely encounter the ninjas from the Mist Village. Uchiha Jing wanted Li Yi to gain some experience.

It's just that in the Rain Country, the suppression of Li Yi's strength is effective to a certain extent, while it has a certain blessing for the ninjas of the Mist Village. After all, it rains all year round in the Rain Country, and Fire Style is not very advantageous here.

But that's what ninjas are like. You won't always be given an environment that suits you. You always have to overcome these to become strong.

Li Yi didn't care about this. Ordinary rain could not extinguish his fire escape.

Just like that, they arrived at the border of the Rain Country. Uchiha Kagami stepped into the territory of the Rain Country without any hesitation. In a war between big countries, small countries are so helpless, and the battlefield will only be held among these small countries.

Just as Uchiha Jing and Li Yi were moving forward, a large amount of white fog suddenly filled the surroundings. Uchiha Jing immediately said, "Be careful!"

Li Yi nodded. He naturally knew that this was the signature ninjutsu of the Hidden Mist Village, the Hidden Mist Technique.

"Swish, swish, swish!" Some sounds of breaking through the air were heard, and Li Yi immediately jumped up. The Ryujin Ruohuo in his hand spun a circle, and all the attacking kunai were knocked away. Uchiha Jing stood still, and it was obvious that he wanted to see Li Yi's performance.

Li Yi does not know wind jutsu, and although a large amount of fire jutsu can also break the mist hiding technique, it is undoubtedly a waste of chakra, so Li Yi naturally would not do so.

However, the Mist Ninja hiding in the dark will definitely continue to attack. At that time, as long as Li Yi finds a flaw, he can be sent to death.

"Swish, swish, swish!" At this time, there was another sound of breaking through the air. Li Yi used the Flowing Blade Like Fire to chop out, and found that this time there was not only a kunai, but also an explosive talisman behind it. Li Yi cursed inwardly and quickly left.

At this time, Li Yi heard the noise, and immediately raised his hand and threw two shurikens over. There was another noise over there, and it was obvious that someone was avoiding the shurikens. This time, Li Yi seized the flaw, quickly formed seals with his hands, took a deep breath, and spit out a huge flaming dragon head.

It was exactly the ninjutsu, fire escape, great fire dragon technique.

Wherever the flame dragon head passed, the fog was evaporated. Facing Li Yi's Fire Dragon Technique, the opponent was obviously not unprepared. Two water walls rose up, blocking him. At the same time, due to the collision between water and fire, a large amount of fog was generated again.

However, this time, because the fog was not produced by the Mist Hidden Art, the ninja from the Mist Hidden Village could not see Li Yi. But they knew the general location of both.
