The secret medicine dissolved the moment it touched his mouth, as if it were not a physical substance but a gentle torrent of energy. This torrent slid down Uchiha Tetsuya's throat, bypassing his stomach and merging directly into his Chakra circulatory system. Then, with incredible speed, it surged precisely toward the location of his eyes in his head.

The atmosphere in the secret chamber instantly froze to the extreme. Fugaku and Shisui both widened their eyes, staring at Uchiha Tetsuya without blinking, their breathing subconsciously slowing down for fear of missing a single detail. They were witnesses to this historic moment, and their nerves were stretched to the breaking point.

Unlike their tension, Qi appeared unusually calm. Everything was within his calculations. Just as the medicinal power was about to surge into the meridians of the eyes, he moved. He extended his index and middle fingers, pressing them together like a sword, and gently tapped Uchiha Tetsuya's forehead. A Chakra that was equally gentle yet vast as the sea was channeled from Qi's fingertips into Uchiha Tetsuya's body. This Chakra did not participate in the healing; instead, like an experienced guide, it precisely enveloped the torrent of the secret medicine, guiding it to flush out those long-dried and clogged eye meridians in the most efficient and safe way possible.

"Ngh!"

The moment the medicinal power officially began to take effect, Uchiha Tetsuya's body shuddered violently, and he let out a suppressed grunt. Intense pain, like a red-hot iron awl, stabbed fiercely into his eyes! It was the inevitable reaction caused by the years of accumulated hidden injuries and stagnant blood being forcibly stripped away and purified under the impact of the domineering yet gentle medicinal power.

Destruction comes before construction; without destruction, there can be no construction! The process of rebirth is inevitably accompanied by the excruciating pain of tearing apart the old world.

Uchiha Tetsuya's face instantly flushed red, blue veins bulged on his forehead, and beads of sweat the size of peas continuously slid down his graying temples. He gritted his teeth tightly, blood even seeping from his gums, and his body trembled violently on the chair, as if he were enduring some kind of torture. Two lines of tears mixed with black stagnant blood flowed from the corners of his tightly closed eyes, leaving two shocking streaks on his aged cheeks.

"This..." Seeing this scene, Fugaku's heart tightened. He subconsciously stepped forward half a step, his face full of worry. "Qi, is something wrong with the situation?"

Shisui also clenched his fists. He could clearly perceive that the Chakra within Uchiha Tetsuya's body was undergoing a violent, almost uncontrollable riot. This painful appearance made him recall the terrible backlash after the failure of certain forbidden jutsu. He had even prepared himself to intervene at any moment, using his own Chakra to forcibly suppress the riot. Could it be that it had failed?

Just as the two of them were filled with doubts, worrying that the worst-case scenario might occur, Qi did not even lift an eyelid. His fingers remained steadily pressed against Uchiha Tetsuya's forehead, his voice as calm as a mountain, carrying an unshakeable power.

"Hold onto your focus, Senior! These are the birth pangs of rebirth!"

As his words fell, Qi increased the output of his own Chakra. If his Chakra had previously been a "guide," now it had transformed into an "engineering team." Under his precise control, this Chakra turned into countless tiny Chakra blades, actively cooperating with the medicinal power to cut, strip away, and then dissolve those hidden injury tissues that were entrenched deep within the meridians like stubborn rocks. This process undoubtedly magnified the pain several times over!

"Aah—!" Uchiha Tetsuya could no longer suppress it and let out a painful roar. His body jerked backward, his hands gripping the armrests of the chair so tightly that his knuckles turned pale from the force. Yet, his consciousness, guided by that deep shout from Qi, held onto the last shred of clarity. He knew this was his last chance; he had to endure it! He thought of the sacrifices on the battlefield, the decadence of the past ten years, and Qi's eyes filled with trust.

Pain, endless pain, surged like waves, one after another, pounding against his nerves. His consciousness floated in a dark deep sea, as if it could be torn apart at any moment. However, just at the moment when the pain reached its peak, everything stopped abruptly. It was as if he had crossed a critical threshold, and all the excruciating pain receded like the tide. Replacing it was an unprecedented feeling of coolness, like rain after a long drought, which instantly spread from his eyes throughout his entire body! That feeling was like a window that had been covered in dust for decades being thoroughly washed clean by a rainstorm; the entire world became clearer and brighter than ever before.

He could even "see" the flow of Chakra within his own body. Uchiha Tetsuya suddenly opened his eyes. Those pupils, which had originally been murky and bloodshot, were now incredibly clear, as deep as two quiet pools of water. He subconsciously channeled the regained ocular power within him. Hum! A scarlet light burst forth in his eyes! Within his pupils, a black tomoe slowly emerged, rotating steadily.

But this was only the beginning! Before Fugaku and Shisui could even let out a gasp of surprise, another change occurred! Beside that tomoe, a second tomoe condensed and formed with an even more rapid posture! Two Tomoe! This was already a state he had struggled to maintain stably even before he was injured!

However, the miracle did not stop there. Under the continuous nourishment of that massive medicinal power, the two tomoe in Uchiha Tetsuya's eyes rotated faster and faster, and an even more powerful ocular power was awakened and gushed out from the depths of his bloodline! This power was so pure, so full of vitality! A third tomoe, in the eyes of Fugaku and Shisui who were shocked to the point of being almost dazed, slowly rotated and precisely landed in its rightful place!

Three-Tomoe Sharingan! That unique scarlet glow, symbolizing an Uchiha elite, bloomed once again from Uchiha Tetsuya's eyes after nearly a decade! That light was so brilliant, so powerful, even surpassing his peak years!

"My eyes... my... Three-Tomoe..." Uchiha Tetsuya slowly raised his hands. Those hands, which he could once only see as outlines due to his blurred vision, were now so clear in his eyes. He could see every palm print on his palms, the faint half-moons on his fingernails, and even the tiny dust particles floating in the air. Inside his body, Chakra surged endlessly, and that familiar yet strange powerful force once again filled his limbs and bones.

Regained! This was truly regained!

This steadfast veteran, who had not even frowned in the face of death on the battlefield, could no longer suppress the excitement in his heart at this moment. Two lines of clear tears rolled down from his reborn Three-Tomoe Sharingan. But he did not wail, nor did he lose his composure. He slowly stood up from the chair, turned, faced Qi, and then revealed a smile brighter than the sun.

"I... am back."
