I just want to lie in Naruto world

  "Ah, Neji has become stronger, and he has surpassed me every day. No, I want to run 100 times around Konoha in a handstand!" Xiao Li set a goal for himself with tears in his eyes.

  "Hahahaha, my lovely disciples, seeing your youthful and high-spirited looks makes my youthful blood boil!" Metkai appeared next to everyone with a teleportation technique, posing as a golden rooster independent OSS.

  "Teacher Akai, I haven't seen you for a long time. Didn't I say that you only need one week to complete the task?" Tiantian said angrily with his hands on his hips.

  "Well, for this, it's Kakashi's fault. When he was doing the task today, he got lost on the road of life, which made our task a bit slow!" Facing the furious Tiantian, Akai threw the blame without hesitation. It's fifty-fifty.

  "By the way, Neji, did you use the Rasengan just now?" Akai asked in surprise.

  "Yes, teacher Akai introduced the Fourth Hokage's Rasengan and my Kaiten last time. They both require no chakra evolution and can directly explode with power."

  "I asked about the Rasengan out of curiosity. You mentioned that it is similar to Kaiten, but the smaller version can be used in the palm of your hand."

  "I haven't had any tasks in the past two weeks, so I developed this technique because I was bored." Neji said in an understatement, as if he was just doing it.

  Of course, it's really simple. You can create more than a hundred shadow clones every day and you can learn it in a week.

  What made Akai's eyes widen was that Tiantian actually stretched out his right hand, the chakra gathered into a ball in his hand, and a Rasengan appeared.

  "Hey! After Neji developed this move, he taught it to me and Xiao Li." Tiantian looked at the Rasengan in his hand with a rather regretful tone. "I just learned the third stage. Now I only have the appearance, and the power is still far behind!"

  "Has Xiao Li learned this too?" Akai looked at Xiao Li again after hearing this, but Xiao Li just touched his hair in embarrassment in response to Akai.

  "Neji divided the Rasengan into four stages. The first stage is to gather chakra in the hand, the second stage is to explode the water ball in the hand, and the third stage is to explode the air ball in the hand."

  "The fourth stage is to gather high-density chakra in the hand, continuously release it, maintain it, and finally solidify it to form a small typhoon."

  "Tiantian is currently in the third stage, and I have only reached the second stage, and I can barely break the water balloon!" Xiao Li took out a water balloon from nearby luggage.

  Unlike Tenten and Neji, Xiao Li used his hands in the same way as Naruto, rubbing the chakra up and down, and finally exploded the water ball.

  The Rasengan does not require seals and can be learned as long as there is chakra, so in theory Xiao Li can definitely learn this trick, but it may take a longer time to learn.

  You must know that Xiao Li, who opened the three doors, was already overflowing with red chakra, but he was still slower than normal people in terms of control.

  The reason why Tenten learned the third stage of the Rasengan in a week was because Neji taught him step by step, unlike Jiraiya who let Uzumaki Naruto realize it on his own.

  Neji directly pointed out all the joint tips, such as how chaotic and irregular the chakra rotation should be, and how to use the pain in the hands to sense the flow of chakra.

  Of course, after his hand was injured, Neji's Palm Immortal Technique was immediately arranged, and the free healing did not delay his training at all.

  "Although Xiao Li is a slow learner, I believe he can learn it, and after learning this move, he will also have a trump card against opponents with strong defenses in the future!" Neji explained to Metkai.

  Unexpectedly, Akai's whole body seemed to be turned to stone. He squatted under the tree and began to read casually.

  ‘I, my disciples, started to learn ninjutsu collectively while I was away! ’

  ‘Am I going to lose the reverence and respect of my disciples? ’

  ‘No, we must not let this happen! ’

  Akai did a beautiful backflip and returned to everyone.

  "Hahaha, it seems that you have really not slacked off during this period, so as a reward, I decided to teach you a new secret skill today, which is my most powerful physical skill, the Eight Gate Dunjia!"

  Akai gave a thumbs up, his white teeth shining brightly.

  Hearing this, not only Xiao Li and Tiantian were shocked, but even Neji began to listen carefully, because everyone knew what this technique meant.

  Seeing everyone looking at him expectantly, Metkai stabilized his mentality and began to introduce to everyone.

  Eight Gate Dunjia is to temporarily gain powerful power by unlocking the channels that bind chakra in the human body.

  The principle is that in the human chakra meridian system, there are eight places that control the flow of chakra. These eight places are the door of opening, the door of rest, the door of life, the door of injury, the door of Du, the door of scenery, the door of surprise, and the door of death.

  The existence of these eight gates is actually to protect the human body from being hurt by its own violent chakra, but after training to actively open these eight gates, one can gain very powerful power.

  Activating it will also cost you physical damage, so the prerequisite for learning the Eight Door Dunjia is to temper your body to make it strong enough to withstand it.

  Through unconventional, overloaded, and long-term training beyond the limit.

  In this way, all parts and organs of the body can be exercised, adapted to the load they bear after being turned on, and the damage to the body caused by the huge energy after being turned on can be minimized.

  That's why Metkai and his son developed a method of chakra bodybuilding to support the practice of Eight Gates Dunjia.

  After briefly introducing the entire Eight Doors Dunjia, Metkai began to focus on the first door of the Eight Doors, opening the door.

  Opening the door unlocks the limitations of the brain. After completing the practice, you can exert 100% of your physical ability, overloading your body's energy to increase your speed and strength.

  After explaining how to open the door, Metkai personally demonstrated it and opened the door. The displayed effect is even more terrifying speed and power.

  Neji opened his Byakugan in time, and through his Byakugan he could see the whole process of Akai's chakra surge in detail.

  After the demonstration, Akai closed the door easily and naturally. Logically speaking, it would cause harm to his body, but it had no impact on him at all.

  This is because after so many years of practice, Akai's body has become very strong and tough. Opening the first three of the eight doors will no longer cause any harm to Akai's current body.

  It just turned into a trick that consumes a lot of energy.

  This also makes Neji more interested in this, because it means that as long as the body is strong enough, the Eight Gate Dunjia can be just a combat mode.

  Just like the Super Saiyan mode of a Saiyan, the combat power is increased dozens of times after it is turned on, but nothing happens after it is turned on. This must be because the body is strong enough to bear the explosive combat power.

  Moreover, the Eight Gate Dunjia itself is a unique technique that squeezes the body. Using it is equivalent to consuming the body. It also complements each other when combined with chakra body training.

  In the training ground, as Akai finished teaching, Neji, Xiao Li, and Tiantian were practicing hard and trying to open their own doors.

  It's a pity that the difficulty of Eight Gate Dunjia is much higher than that of chakra training, so it is not that easy to learn.

  In the next few weeks, the three students in Kaiban spent their free time learning to open doors, and they began to compete with each other.
