After Naruto enters the Tower of the Ascended Emperor, he faces directly to the library as he thinks about priorities. He knew one of the characteristics of a ninja is speed. Then he thought a little about the fourth generation of Hokage.
He went straight to the speed rack and showed many techniques, the most prominent of which were the "shadow steps" that caught his attention and read its introduction: light as wind hidden as a shadow of ten and a hundred and a thousand pictures later, gain: high speed and later pictures to confuse the opponent.
It wasn't a difficult technique, it was easy to practice so he chose it.
Then he went to the physical technique shelf even though the Mammoth Suppressing Hell art gives him a strong physique that he is eliminated in his beginnings and is not immune to attacks with sharp weapons.
So he flipped through several books and set his eyes on two books, "Tyrant Armament Haki" and "Indestructible Heavy Body Technique."
Tyrannical Armament Haki: It can be opened and closed from the skin as hard as iron.
The "Heavy Body Indestructible Technique": A high-quality physical technique that hardens bones and muscles to a terrifying degree. It consists of ten levels, with each level giving its user a solid and massive weight in strength, where the first level becomes the skin as solid as gold with an increase in the weight of the arm and body b 100 tons of raw material.
The difficulty of this technique is very great and it is very difficult to reach the first level only, but this does not prevent it from not being practiced, with this technique and the Mammoth Hell Suppression technique, it is invincible in the ninja world.
Naruto knew that a technique would cost many medicinal materials and the blood of high-level monsters until he was lucky to have the Ascendant Emperor's Tower to close the material gap.
Then he went to the boxer's technique rack and it didn't take long before he chose one "Dragon and Elephant Boxing" and found it very suitable for his current situation as this technique allowed him to raise his punch power to a higher level and utilize all his strength.
Then he went to the Weapon Arts Shelf and chose a good spear technique, "The Basic Spear Thrust."
He walked out of the library to his training ground and started practicing Shadow Steps (Mastery Levels: Beginning. Small World. Big Realm. Mastery State. Perfect State).
Half a day later
He reached the Junior Realm level at Shadow Steps and then proceeded to train for the Tyrannical Armament Haki
Time passed quickly to the fifth day
From training in Armament Haki and he quickly reached a state of mastery thinking: My body seems to be very resilient He looks at his shiny black hand about being scratched with a small knife but the knife shattered.
And the surprise does not come alone. He succeeded in forming the second mammoth, and his raw strength became 28 tons per arm, and he rose directly to the fifth level of qi intensification, and he is sure that he can fight Kai if the third or fourth door is opened.
He is thinking of going up to the second floor to start refining his martial skills and collecting some monster blood, so he continues to practice both Shadow Steps and Tyrannical Armament Haki and start practicing Dragon Boxer and Elephant poses....
Until the 8th he decided to enter the second floor.....
