In the blink of an eye, three days passed, and a large Library was erected near Hidden Leaf Hospital.
For ordinary people, this is a workload that cannot be completed in a month, but for ninjas, it only takes three days.
Among them, Might Duy and Might Guy performed the most eye-catchingly. They could carry more than ten trees at a time, even thicker than their waists, and their calves could run very fast.
But what makes the surrounding ninjas feel the weirdest is that after work, the two of them are always inexplicably moved, shouting about passion and youth.
In this regard, Obito is also a little helpless.
After several months of recovery, Might Duy's injury has almost recovered. The previous turmoil about Root has also disappeared with the death of Danzo.
Might Duy was very touched by Obito's help. He knew that he could save his life this time and had no serious health problems. He would be able to continue practicing Taijutsu in the future, thanks to many precious medicinal materials.
As a Genin, Might Duy couldn't afford the money, so he decided to work with his son to pay off the debt.
Having said this, Obito had no choice but to accept it.
His help to Might Duy was purely based on their potential.
After all, Might Guy is the man who almost kicked out Six Paths Madara in the finale. They and their son think it is worth investing.
At this time, at the reception desk on the first floor of Library, Might Duy was sitting on a chair nervously.
Although Obito and Sarutobi Hiruzen reached a tacit agreement and would no longer hold Might Duy responsible, but through Obito's secret operation, Might Duy was exposed and retired honorably early.
And Obito provides a job for Might Duy who is waiting for employment, that is, Library receptionist.
Library will be the storage place for thousands of secret books from now on, and the defense work must be extremely strict.
Obito plans to build a set of interlocking magic circles in Library to ensure that no one can sneak in or break in secretly.
These arrays can be controlled by some Uchiha Clan elites to ensure Library's safety at all times.
But this is just a conventional method. If it encounters the destructive level of Tailed Beast, Library may not be able to stop it.
Therefore, Obito specially arranged for Might Duy to be the presence of Library. He usually acts as an ordinary receptionist. Once the situation is critical, he can play an unexpected role.
On the underground level of Library, array patterns are spread all over the ground, which is strange and full of mysterious beauty.
Obito stood aside and sighed in annoyance, "The key is still the energy issue!"
Energy is always conserved. As far as the formation is concerned, various mysterious and strange patterns are like various circuits on a circuit board, but they must be plugged in to be effective.
Although the various materials used to carve the array patterns are also very precious, they are only a drop in the bucket for the Uchiha Clan, which is the best-selling product Ninja World today. The key is that the energy problem cannot be solved.
What is now inserted in the center of the array is a unique crystal of Ninja World. It is completely purple. Once activated by energy, countless star-like light spots will flash inside the crystal, so it is named Star Crystal.
The uniqueness of Star Crystal is that there are countless slightly invisible hollow bodies inside, which can store energy and be activated under specific conditions to release energy. However, after these energy are transformed by Star Crystal, there is a substance that is lethal to humans and cannot be absorbed by the human body.
The earliest application of Star Crystal can be traced back to the time when Onmyoji was not dead in ancient times. At that time, Onmyoji used Star Crystal as the energy core to arrange the sealing array.
Today's Ninja World and Star Crystal are also widely used.
For example, the outermost part of Konoha has always been in charge of Sealing Squad. It has a warning and protective barrier. The energy core used in this barrier is Star Crystal.
Konoha Ninja generally inputs chakra into Star Crystal in advance, and changes the state of Star Crystal when activating the barrier. Star Crystal will automatically output it along the Sealing Jutsu pattern that forms the barrier.
Even the energy source of the one-time seal scroll made by Obito is also Star Crystal, which is hidden in the shafts on both sides of the scroll. The user only needs to open the scroll and press the protrusion of the shaft handle, and Star Crystal will change its state, and the chakra stored in it will automatically flow to the spell written on the scroll surface.
Generally speaking, Star Crystal is similar to a rechargeable battery, so its biggest disadvantage is obvious, that is, it cannot be replenished quickly and in time.
Take the formation designed by Obito in Library as an example. The formation itself can block the destructive power of Kage Level or even Tailed Beast, but the energy in Star Crystal will be consumed quickly, and while Star Crystal maintains the state of outputting energy, Star Crystal cannot replenish energy.
Once the energy is exhausted, the formation will collapse.
It is precisely with this in mind that Obito specially arranged for Might Duy to be the receptionist as the last layer of insurance.
After all, Eight Inner Gates of Might Duy is very powerful. After opening the six doors, it can compete with the strong Kage Level. When Seventh Gate is opened, it is even more powerful among Kage Level.
"Before the Infinite Tsukuyomi plan, maybe we can capture a Tailed Beast to study it." Obito touched his chin and frowned in thought. Tailed Beast claims to have an endless supply of chakra, maybe it is the Ninja World version of the green nuclear power plant.
At this moment, Obito discovered through the monitoring array that many clan leaders had walked into Library. A smile appeared on his lips, and his figures disappeared in the basement.
In the appraisal room on the first floor of Library, Might Duy opened the door and walked in, followed by a group of impatient clan leaders.
Among them, Aburame Shibi is the most urgent. Their family really loves bugs. They know hundreds of ways to strengthen bugs, and they feel as if a cat has scratched them. They feel very uncomfortable.
Obito sat leisurely on the wooden chair, waved his hand, and pointed at a pile of identical posts on the table. "Don't worry, these are the detailed regulations of Library, you should take a look first."
Nara Shikaku picked up a post and browsed it quickly.
"The points the family has in Library belong to the family points. The redeemed secrets can be freely taught within the family, but the family points cannot be traded."
"The points saved by ordinary ninjas in Library are personal points. The redeemed secrets can only be taught to immediate family members and spouses, but they can be traded freely."
"In addition, after an ordinary ninja dies unexpectedly, if he has designated an heir in Library during his lifetime, the points in his name will be transferred to the heir; if there is no designation, the points in his name will be equally distributed among his immediate family members and spouse."
"Warning, secrets can only be taught within the prescribed scope. Once illegal teaching behavior is discovered, the points of the teacher and the person being taught will be cleared, and they will no longer enjoy any rights and interests in Library, and will be held responsible for leaks."
Nara Shikaku read it from beginning to end and nodded towards Yamanaka Inoichi and Akimichi Choza.
"Since everyone has no objections, the redemption of points can begin." Obito sat up straight and said seriously.
"I'll come first." Aburame Shibi said simply, taking down the huge scroll he was carrying. "Here are all our Aburame Clan's secret techniques, including Kikaichū, Insect Clone, Insect Sphere, etc..."
