17 Chapter 17 - Obstacle to Awakening the Sharingan

"Problems with mental strength?" Yusuke frowned slightly. In the shinobi world, mental power is a relatively common term and if one develops this power to a certain level, it is defined as Yin Release.

"Exactly, but to be completely sure, I'll have to confirm it." Fugaku's expression turned serious. "Yusuke, you know that the Sharingan with three tomoe can be developed into even more powerful eyes, they are much stronger than the Sharingan and have much stronger abilities!"

"Are you talking about the Mangekyou Sharingan?" Yusuke nodded slightly, indicating that he understood what was being said. Moreover, he knew that Fugaku had already awakened this power, but kept it from the clan for his own reasons.

Fugaku was not surprised by Yuusuke's knowledge. He already guessed that the guy knew about everything from the clan's records.

"Yes, the Mangekyou Sharingan are eyes whose power is much greater than that of a regular Sharingan, the abilities of each individual member of the Uchiha clan who awakened him will also be different," Fugaku decided to tell Yuusuke everything he knew about the power of these eyes.

"So an Uchiha with and without a Mangekyou Sharingan are completely different levels of power! And in front of you sits the one who was able to awaken him! Fugaku proudly declared.

Although Yuusuke remained impassive, he was smiling in his heart. He also knew that this clan leader still held a grudge for losing one of his sleeves in the last sparring, so it was a hint that he hadn't done his best in the previous sparring.

"However, no one in the clan knows yet that I wield the Mangekyou Sharingan, so you should also keep it a secret and not tell anyone else," Fugaku said with a serious face.

"I understand. So, getting back to my problem, how are you going to check my condition?" Yusuke asked and as soon as he finished speaking, he saw Fugaku's eyes begin to change. At first, it was a regular sharingan with three tomoe, after which, the tomoe in the pupil began to merge until they turned into a unique pattern. The pattern consisted of three rotating curves around the pupil with three dots near each, which twisted around the pupil counterclockwise.

"I will penetrate your inner world with the unique ability of my eyes, so I can find out the true cause of your problem!" Fugaku slowly said while looking at Yuusuke.

After hearing Fugaku, Yusuke hesitated, after all, everyone had their own secrets. He wasn't sure how much Fugaku could see.

Meanwhile, noticing Yusuke's hesitation, Fugaku could easily guess what he was thinking: "Don't worry Yusuke, you can feel the whole process and even observe with me, I promise, apart from checking the integrity of your spiritual world, I will not delve into anything!"

Yuusuke thought for a moment and finally decided to take the risk. Of course, this did not mean that he now completely trusted Fugaku, he simply believed that if the unexpected happened, Ryujin Jakka would help him kick Fugaku out.

"Okay, I agree with Fugaku-sama, but I must warn you, you must be careful with my spirit world, there is something there that can destroy any illusion that negatively affects my mind." Yuusuke did not want Fugaku to suffer from the backlash Ryujin Jakki. In the end, despite all the power of the Uchiha clan in mental techniques, they will never be compared in this aspect with the world of death. Ryujin Jakka is an extremely powerful spirit from that world, and as the young man guessed, he most likely did not lose his power, it's just that he, Yusuke, does not know how to release his full power.

Uchiha Fugaku looked at the young man in puzzlement, who in turn shook his head and laughed: "You will understand everything as soon as you enter my spirit world and see it."

Since he had to let Fugaku look into his spirit world and unravel the reason why his sharingan couldn't awaken, Yuusuke couldn't hide from him the fact that there was a zanpakutō hidden in his spirit world. However, Yusuke did not bother to tell him about the power of the Zanpakutō and other information.

Fugaku nodded, "Let's start then!" As soon as those words left his mouth, Yuusuke saw the pattern in Fugaku's eyes begin to rotate rapidly, then, Yusuke plunged into darkness for a moment.

In the middle of the vast wasteland, a giant katana hovered in the air, surrounded by blazing flames. The flames flowed like the current of a river, along the beautiful edge of this majestic blade. The katana was so huge that its tip slightly rested on the ground, and the hilt disappeared somewhere in a sea of ​​clouds.

Around the giant katana, countless bubbles hovered, looking at them, Yuusuke could see that these bubbles were filled with his thoughts, memories and knowledge.

"So this is what my spirit world looks like? What a strange feeling, this must be Ryujin Jakka true body, Yusuke thought as he gazed at the towering blade engulfed in mighty flames.

At that moment, Fugaku's figure appeared beside him and he stared at Ryujin Jakku with a shocked face. The size of this blade

hit the head of the Uchiha clan to the core. He had never seen such a spectacular sight. To think, something like that was hidden in the spirit world of a teenager.

"What blade is this?" Fugaku asked in a trembling voice as he swallowed a mouthful of saliva.

"I don't know for sure, he has been with me since my birth, I only know that his name is Ryujin Jakka!" Yuusuke's voice sounded above the ground.

"No wonder you were able to break out of my illusion so easily, I never thought you had something like that hidden! You are truly a unique person!" Fugaku sighed while looking at the giant blade. At the same time, he was finally able to convince himself that Yuusuke had a chance to become as powerful as their ancestor Uchiha Madara.

Fugaku then spent some time looking at the flaming blade, "Yusuke, I think the reason your eyes haven't opened yet is because of that blade!"

Hearing Fugaku's words, Yusuke was not surprised, his voice sounded in the spirit world, "I suspected it, but I didn't feel any negative influence from him on my spiritual power, so I ruled out this reason."

"It's because you were born with it! Just as an ordinary person will not feel the circulation of blood in his body, you will not feel any discomfort from him either, because he is part of you! Fugaku said and continued after a pause. "The blade itself does not have a negative effect on you, but your spirit world is a completely different matter, this blade strongly protects it!" Due to the protection of this blade, your spirit world is so stable that it can hardly produce any fluctuations. And to awaken the Sharingan, your spiritual world needs intense stimulation!"

Uchiha Fugaku gazed in awe at the huge katana engulfed in flames. Today, the horizons of his thinking have greatly expanded, now he no longer feels such pride due to the presence of a mangekyou sharingan.

After hearing Fugaku's explanation, Yuusuke also thought about it.

"Fugaku-sama, are you saying that as long as a strong mental force flows into my spirit world and I am able to break through Ryujin Jakka defenses, I will be able to get the necessary stimulation and awaken my sharingan?" - Yuusuke decided to clarify.

"That's the only thing that comes to my mind. But, I'm not sure I can build up enough mental power to help you break through that blade's barrier!" Fugaku replied with a disappointed sigh.

From what he understood, Yusuke had almost lost the opportunity to open his sharingan. But remembering the majestic blade, Fugaku cheered up again. Perhaps the strength of this blade will not be completely worse, and maybe even better than the strength of the Sharingan.

Then they both returned to reality, everything that happened in the spirit world was just a moment in reality.

Looking at Fugaku, whose left eye was covered in blood and constantly oozing blood, Yuusuke was grateful that the other person had done everything possible for him.

"Fugaku-sama, are you okay?" Although he knew that these were the consequences of using the Mangekyou Sharingan, Yuusuke still showed some concern.

Fugaku waved his hand, "It's okay, it's just an excessive consumption of pupil energy. I need to get some rest, so if there's nothing else, you can come back too."

When Fugaku awakened his Mangekyou Sharingan, he was able to read more information on the Uchiha clan's stone tablet. There he was able to learn about the consequences of overusing the power of these eyes.

"Thank you, Fugaku-sama." Yuusuke stood up and bowed very low as he paid his respects. With this, he also wanted to express his gratitude for Fugaku's efforts, then he left the clan seat.

Walking down the road, Yuusuke's heart was filled with excitement. Not only did he come up with a way to solve his Sharingan problem. But he was finally able to understand the reason why Ryujin Jakka never displayed the same level of strength as a Shinigami.

"Soul power, spiritual power and yin chakra, I need to ask Orochimaru about it while he's still here! Although his forbidden technique, Living Corpse Reincarnation, has yet to be finalized, some discoveries about the technique's weaknesses must be made. I think Orochimaru will not refuse if I now offer to work together on a technique to enhance the strength of the soul!

Sarutobi Hiruzen sat in a chair and looked at Shisui, who was on one knee, waiting for the old man to speak.

Sarutobi Hiruzen exhaled a cloud of smoke and slowly asked, "And what is his answer?"
