Pushing open the door of the room on the far right, accompanied by the 'ping-pong-pong', a wave of heat hits in an instant, causing Kaguyasu to involuntarily increase his breathing by two points.

Looking at the three figures sweating profusely inside, Kaguyasu asked loudly, "How is the progress?"

Hearing this familiar voice, the three figures with exactly the same faces as Kaguyasu, put down the hammer, serrated tools in their hands and looked at the door: "The accuracy of handmade creation is too poor, the yield rate is too low, and the accuracy you require for the equipment this time is relatively high, and the completion time is probably much later than expected."

Although the ninja world currently has electric lights, black and white TVs and other items, it has not been used as in the previous life (defense of harmony).

Many equipment needed by Kaguyasu, including microscopes and differential centrifuges in the biological laboratory just now, cannot be bought on the market, and he needs to forge it himself.

"No rush, priority is given to ensuring the accuracy of the equipment."

The Second Ninja Battle has just ended, and there are still several years of peace before the Third Ninja Battle. Kaguyasu has enough time to complete the expected experiments and verify some of his conjectures.

After telling the three of them to refresh their status, Kaguyayu left the three adjacent rooms and moved to a thick metal door on the far left side of the hall.

Instead of pushing the door directly into the door like before, he first pressed the door bell on the left hand side of the door, and waited until the indicator light on the door turned from red to green before Kaguya was able to open the door.

Compared with the previous three rooms, the area of ​​this room is much larger, which is about the sum of the three rooms.

However, except for a familiar figure, the inside was empty, with pits on the ground, and there were many pits of different sizes suspected to be caused by explosions.

Before Kaguyasu could speak, the shadow clone complained first: "Original, you are here. If you are a little later, maybe I will explode like those guys."

"When developing a new ninjutsu, there will inevitably be a little accident." Kaguyayu was distracted by this and changed the topic: "How is the nature of the fire attribute chakra practiced?"

This room is specially used to develop ninjutsu and practice chakra's nature and form changes, and it is also the most solid of all rooms.

"It's not that easy." Shadow clone was speechless: "This is the attribute you are the worst at!"

Of course, Kaguya knew that practicing without changing the nature of chakra would not be so easy. It was just to change the topic and asked with the attitude of "if a miracle happens."

In the original work, even the two Konoha elites, Money Unit of Measurement and Chakra Unit of Measurement, are only proficient in the chakra nature and form changes of two and three attributes.

Only Sarutobi Hinaru, who is known as the "strongest Naruto in history", and those who are suspected of having 13 in the late period, are suspected to be proficient in the nature and form changes of the five elements Yin and Yang attributes chakra.

For ordinary ninjas like Kaguyasu who has no father to send him off, the practice of chakra's nature and form changes is entirely water grinding skills.

Even with the help of Shadow Clan, it takes a lot of time to practice to master it.

Although the other party was just a shadow clone, Kaguyasu still maintained basic respect for him: "Thank you for your hard work today, prepare for a refreshing state."

After leaving this practice room, Kaguyasu did not go to the last room, which was the room on the right side of the hall.

It was just a warehouse for storing idle items.

After returning to the biology laboratory and taking the nutrient solution of "Tronsu No. 3" from the No. 4 Shadow Cluster, Kaguyasu left the underground base that cost most of his money.

Back in the living room, Kaguyasu did not stay too much, but chose to go to the bathroom.

Take off his robe, sit cross-legged in the dry bathtub, pull out the rubber plug on the head of the test tube, and drink the nutrient solution inside, Kaguyasu's index finger and middle finger together to form a sword, cross the word "Ten", and chant lightly: "The technique of shadow clone is solved!"

‘Bang!’ ‘Bang!’ ‘Bang!’…

The next second, the figures sitting or standing in the underground base instantly turned into a handful of white mist, carrying the memory and experience accumulated for several days, and following a channel that could not be observed by conventional means, they rushed to the figure sitting cross-legged above their heads.

What followed was also fatigue and pain accumulated for several days, which made Kaguyasu's originally calm face instantly put on a mask of pain.

If it weren't for the support of Tronsu No. 3 nutrient solution, this huge fatigue would probably directly blow his body down.

But compared to mental pain, physical fatigue can only be regarded as a disease of scabies.

At the moment when the Shadow Clan Art was removed, the huge memories accumulated by the ten clones in the past few days rushed into Kaguyasu's mind. The scenes of hundreds of movies were played in less than a thousandth of a second, causing his brain to fall into a brief downtime.

Immediately afterwards, I took a cold shower after a hangover, and my body was not dry and I turned on the air conditioner and then burst out from the inside out after sleeping.

Even though it was not the first time that he had experienced this pain, Kaguyasu still couldn't help but let out a painful hum, tightening his teeth, allowing the veins near his neck and temples to be beat constantly.

At the same time, a stream of white smoke emerged directly from the top of his head. His originally handsome face was extremely ferocious due to the severe pain, and was as red as a cooked river shrimp.

After lasting for nearly ten minutes, Kaguyasu suddenly felt the Tianling Gai relax, the pain from his brain receded like a tide, and his hideous face gradually calmed down.

"Huh~"

After breathing slowly, Kaguyasu suddenly opened his eyes, his eyes that were clearly distinguished by black and white were as bright as stars, incompatible with the tired face.

Feeling the slippery body, Kaguyasu immediately turned off the shower switch beside him, and the warm water flowed down from the silver-white spray head above his head, washing away the sweat stains on his body and the fatigue in his body.

Although the Shadow Cloning Technique does not have the maneuverability of the Flying Thunder God Technique, does not have the most powerful lethality of killing ashes, nor does the sealing ability of the Earth-Breaking Sky Star, in terms of practicality, it is definitely a strong contender for the first place among all ninjutsu in "Naruto".

From the rookie ninja who just graduated from ninja school to the group of non-humans at the Sixth Path Level, this ninja can help the caster a lot.

Moreover, due to the mistaken demonstration of the prince using shadow clones to assist in the rubbish in battle in the original work, many people have ignored the true nature of this B-level ninjutsu.

The essence of Shadow Clan Art is not to help fight, but to assist in review and practice.

Because after the surgery is removed, the memory and experience obtained by the clone during this period will be instilled into the body.

Learning the Shadow Clan Art is equivalent to having a plug-in with multiple experiences. This is why Kaguyasu chose to exchange for this ninjutsu after he obtained enough military achievements.

Think about it, you only need to eat, drink and have fun every day, and leave all the learning things to the shadow clone to do, and you can gain a lot of knowledge every once in a while. What a bug.

If Kaguyasu had this ability in his previous life, let alone Tsinghua University, Peking University, and the two colleges, Zhe Wanshi, might be like taking pictures of him. Only the Nobel Prize may be a little bit challenging.

He will also become the most popular person in the world.

Without it, learning makes people happy!

But this ninjutsu is not without flaws.

First, the character of the created clone is uncontrollable and may have obvious differences from the original body.

Second, the fatigue accumulated by the clone will be added to the caster at the moment of releasing the surgery. A large amount of information may destroy the caster's brain.

A weaker caster may die before he enjoys the benefits brought by the shadow clone.

With Kaguyasu's current physical fitness, maintaining the fourteen shadow clones for high-intensity study and work without damaging the body and potential and maintaining sufficient efficiency is the limit.

Every three days or so, he will recycle, absorb and organize the knowledge and experience accumulated during this period.

If you are lucky, you may also have new inspiration due to the collision of a lot of knowledge.
Chapter completed!
