After Mu Yue rescued the injured Konoha ninja, the disciples also took action to rescue the Konoha ninja and attack the Iwagakure ninja.

They did not have Mu Yue's strength, so the three of them acted together, and they were not too far away from Mu Yue.

At first, the three of them seemed a little confused, because the scene was so chaotic. Even Kakashi, who had the most experience before them, had never experienced such a big scene, with thousands of ninjas fighting in a melee.

However, they had just experienced a difficult life-and-death fight not long ago. Although they were a little confused for a while, their combat effectiveness was still online.

Seeing that the three of them were short in stature and looked like newcomers to the battlefield, Ariwagakure picked up the kunai and attacked the three of them.

Metkai immediately entered the state of Rock Breathing and activated the Eight Doors Dunjia.

"Eight Gate Dunjia, open the door, open it!"

Using the Breathing Technique and Eight Door Dunjia at the same time greatly improved Metkai's physical abilities.

Whoosh!

"Konoha Great Cyclone!"

Chakra erupted from Metkai's feet, and he disappeared in front of the Iwagakure Ninja with a teleportation technique, and then kicked out a whirlwind leg very quickly, kicking the Iwagakure Ninja away.

"Fire Release: Impatiens Flower Claws Red!"

Obito used his breath of fire to enhance his fire escape ability, and quickly threw three flaming kunai towards the Iwagakure ninja who was knocked away.

Boom!!

When the flame kunai hit the Iwagakure ninja, an explosion immediately occurred, and the intense fire enveloped his body.

The high temperature and explosion of the fire release, and the powerful piercing power of the kunai, the attacking Iwagakure ninja turned into a charred corpse and fell from the air under the combo attack of Obito and Metkai.

"Just fight like before." After successfully defeating an enemy, the confusion in Obito's eyes dissipated.

"You shouldn't have used ninjutsu just now, just throw out the shuriken and kunai." Kakashi shook his head and said.

Originally, he was preparing to attack with shuriken, but he put it down after seeing Obito use ninjutsu. After all, ordinary ninjas would definitely not be able to withstand the fire attack bombardment.

"Why? If it's just a ninja tool, I don't think it can kill him in one go." Obito asked in confusion.

He believes that if the enemy can be eliminated, he should defeat the enemy completely in one fell swoop to lose his ability to fight, to prevent accidents in the battle.

"It's no problem if it's a normal sparring. It's no problem if there are only a few enemies. But look at how many enemies there are here. You must save your chakra as much as possible." Kakashi expressed his opinion.

Although he has never experienced a big melee with thousands of ninjas, Kakashi feels that it is necessary to conserve physical strength on the battlefield and use the least amount of physical strength and chakra to achieve the greatest results.

For example, what Obito did just now, even if he didn't use fire escape, he and Obito used ninja tools together, the enemy would be seriously injured even if they didn't die for a while. Being injured to this extent on the battlefield is almost equivalent to death.

"Akai, you too, don't expend too much energy." Kakashi then said to Metkai.

Full Concentration Breathing and Eight Gate Dunjia are both good skills to enhance strength, but they also consume a lot of physical energy.

Obito glanced at the battlefield where there were still many enemies, and had to admit that what Kakashi said did make sense.

The war was completely different from their previous battles. He could guarantee that it would not be a good thing to consume too much chakra and physical strength here.

Metkai also nodded, agreeing with Kakashi's point of view, and decided not to use full concentration breathing and the second door unless he encountered a too strong enemy.

In fact, Kakashi didn't say anything. If the enemy is strong enough and has a high status, then it makes sense to spend more energy to kill, but this is not something they should think about with their current strength.

Kakashi pulled out the White Fang short blade from his back. Compared with using ninjutsu, it was obviously more labor-saving to kill the enemy with a knife.

He had already banned the two high-consuming ninjutsus of Purple Lightning and Pseudo Darkness in his mind. Although these two ninjutsus were very powerful, he would have no chakra after using them twice.

Obito took out another ordinary kunai from his ninja tool bag, preparing to preserve chakra to use ninjutsu at critical moments.

In fact, he also brought the birthday kunai that Mu Yue gave him with him, but Obito was worried that it would be damaged in the battle, so he didn't take it out.

Even if they don't use ninjutsu, the level of taijutsu of the three of them is not bad. Coupled with the tacit cooperation, even against the same number of Iwagakure chuunin, Kakashi and the others can steadily defeat the enemy.

However, Mu Yue's efficiency was obviously faster than theirs. A dragon fire easily eliminated the Iwagakure jounin, and he also held a standard kunai and killed several Iwagakure ninjas as quickly as he could chop melons and vegetables.

"Teacher Mu Yue is still very good, but why didn't Teacher Mu Yue use the fire escape with a huge range before? Is it because he was worried about hurting his companions?" Obito lamented that Mu Yue killed the enemy quickly, but also felt a little doubtful in his heart.

"Teacher Muyue must have his own considerations in mind. It's better to worry about yourself more. We seem to be being targeted." Kakashi reminded quickly.

Kakashi paid more attention to their surroundings, and he suddenly discovered that several Iwagakure were approaching them intentionally or unintentionally.

Not long after Kakashi finished speaking, five Iwagakure immediately jumped up and rushed toward them.

One Iwagakure was stopped by a Konoha ninja on the road, but four Iwagakure continued to rush towards them.

"With such strength at such a young age, he must be a genius in Konoha. Kill them first!" Iwagakure, who was at the forefront, shouted.

Mu Yue, who was always paying attention to her disciples, saw this scene and used appraisal to test the strength of the four Iwagakure. She found that there was only one jounin with 5,000 chakras but no proficient skills and three chunin with 3,000 chakras, and then continued.

own actions.

The leader Iwagakure Jonin approached Metkai and quickly stretched out his fist, condensed a large amount of chakra into his right hand, and then changed its nature.

"Earth Release·Rock Fist!"

Iwagakure Jōnin's right fist was covered with earthy-yellow rocks, and its hardness and power were greatly improved.

But Metkai was already prepared, chakra condensed on his feet, and he burst out and dodged several meters at extremely high speed.

Boo hoo hoo!!

Taking advantage of this opportunity, Obito and Kakashi quickly threw out their shurikens.

Dang Dang!!

The rock fist of Iwagakure Jonin is very hard, and he can fly away all the incoming shurikens by swinging the rock fist wide and wide.

At this moment, the other three chunin also reached an effective attack distance, and they spit out sharp stones that flew extremely fast towards the three of them.

"Earth Escape·Earth Flow Wall!"

Bang bang bang!!

Kakashi quickly formed a seal and controlled a thick wall with a dog's head to rise from the ground, blocking all incoming flying rocks.

Although he first proposed saving chakra, it was obviously not the time to save chakra in this situation.

"Bullying a few children is nothing." A Konoha ninja saw the young ninjas in his village being besieged and wanted to help Kakashi and the others deal with Iwagakure.

But he obviously overestimated his own strength and started a close combat with the Iwagakure Jonin. As a result, he was punched by the Iwagakure Jonin and vomited blood and flew away. The Iwagakure Chuunin also continued to spit out flying rocks for follow-up attacks.

"The second gate of the Eight Gate Dunjia, close the gate and open it!"

Seeing that the Konoha ninja who wanted to help them was injured, Metkai directly opened the second gate of the Eight Gate Dungeon, concentrated his breathing, and burst out with extreme speed to catch the injured Konoha ninja.

"Fire Release·Phoenix Immortal Fire Technique!"

Obito formed a seal quickly, concentrated his chakra on his throat and spit out a large number of small fireballs that just happened to bypass Metkai's body and explode the incoming flying rocks.

Metkai fell behind the earth flow wall and put down the injured Konoha chuunin.

"I'm sorry, I was a little reckless. I didn't expect the enemy to be so strong." The injured Konoha chuunin said to the three of them with an apologetic look.

He was really doing a disservice. Not only did he fail to relieve the pressure on the three of them, he also forced them to use ninjutsu to rescue them.

"Senior, you have done your best, leave the rest to us!" Metkai gave a thumbs up to the Konoha Chuunin and showed a bright smile.

"Don't call him a Rock Fist, even an Iron Fist would roast him." Obito has full confidence in his Fire Release Ninjutsu.

Kakashi gave Metkai and Obito a look, and they both nodded.

"Art fire escape ho fireball!"

Obito suddenly jumped out and spit out a three-meter-high hot fireball.

"Breath of the rock, concentrate on breathing!"

Immediately afterwards, Metkai concentrated his breathing to the limit, allowing his body to reach the limit of strengthening, and rushed out under the cover of the huge fireball.

Kakashi separated a shadow clone and also rushed out of the earth flow wall. The main body used earth escape to slowly approach the Iwagakure Jonin underground.

While Obito and the others were rescuing people, three Iwagakure chunin came behind the Iwagakure jounin.

They worked together to use Earth Release Ninjutsu to block Obito's powerful fireball, but they failed to respond to Metkai's surprise attack.

"Ultimate Konoha's powerful whirlwind!"

Metkai appeared next to the four Iwa ninjas, poured all his strength into his legs, and kicked out as hard as he could.

Bang bang bang!!!

The three Iwagakure were kicked until they vomited blood and flew backwards. Only the Iwagakure jounin blocked the blow, but there was also a crack in the Iwagakure hand.

"How is it possible? It's so fast!"

"Such a strong force. Could it be that he is actually a short, middle-aged ninja?"

The severely wounded Iwagakure chuunin was filled with doubts. It looked like Metkai was definitely no older than ten years old, but his physique was abnormally strong.

They feel that even if they started exercising before they were born, they would not be able to train their bodies like this.

"Pure taijutsu actually has such power, I must kill him!" Iwagakure Jōnin was also very surprised.

Because he found that if he only used taijutsu, he might be beaten violently by a child less than ten years old in front of him. He was a jounin.

Iwagakure Jonin had a premonition that if Metkai did not die in the war, he would definitely become a strong taijutsu expert in the ninja world.

In order to obliterate this future strong man, Iwagakure Jonin unleashed his strongest strength and launched an extremely heavy offensive towards Metkai.
