Life Potion!

"Life Potion: A potion made from life energy that can quickly repair the cells in the human body. Long-term use can improve one's constitution. Exchange prices are as follows!"

"Small bottle: 100 points! (Note: At the Genin stage, one bottle can be used three times; at the Chunin stage, twice; and at the Jonin stage, once!)"

"Medium bottle: 500 points! (Note: Not recommended for use at the Genin stage. At the Chunin stage, one bottle can be used three times; at the Jonin stage, twice.)"

"Large bottle: 1,000 points! (Note: Recommended for Jonin and above. One bottle can be used three times!)"

Seeing that the system offered something useful to him that he could afford, Li let out a slight sigh of relief. As long as it was available, that was enough. It was a little expensive, but points were meant to be spent. He wouldn't begrudge parting with them.

At the Genin stage, a small bottle of Life Potion could be used three times. That meant he could exhaust his chakra each time, drink some Life Potion, and push himself to the limit while refining more. One small bottle would give him three attempts. His chakra was currently at the threshold of elite Genin, so the small bottle was perfect for him.

"System, exchange ten small bottles of Life Potion for me!" Li didn't hesitate. He spent 1,000 points on ten bottles. He was desperate to get stronger.

As soon as Li gave the command, ten bottles of emerald-green potion appeared in front of him. Each bottle was only ten centimeters tall and about as thick as a thumb. They were made of plain white glass, but the Life Potion inside turned them emerald green.

After exchanging for ten bottles of Life Potion, Li had only 9,000 of his 10,000 points left. He put the bottles away and hurried out of the System Space, eager to test how well the potion worked.

In the courtyard, Li took a slight breath, then began forming Hand Seals. "Fire Release: Great Fireball Technique!"

A scorching fireball rolled forward like a wheel. Li didn't stop there, continuing to drive the chakra inside him. The fireball grew larger and larger, from its original one-meter size to one and a half meters. Then he could no longer maintain it. The fireball shot forward, rolling for more than ten meters before bursting apart and disappearing. This Great Fireball Technique was twice as powerful as the previous one.

"I've already used up about half my chakra?" Li nodded slightly. It seemed this method would work. Increasing the Great Fireball's destructive power required as much chakra as casting it twice, which was perfect for quickly draining all the chakra in his body.

With a plan in mind, Li wasted no more time. After two consecutive enhanced Great Fireballs, the chakra inside him was nearly depleted. Without hesitation, he took out a bottle of Life Potion, unscrewed the cap, and drank a third of it. The potion had no taste, like drinking water; it didn't have the fragrance he had imagined. But as soon as he swallowed it, it took effect. His powerless body felt as though it had been immersed in a hot spring. A wave of warmth spread down through his whole body, and in an instant, he felt full of strength. Li immediately sat cross-legged on the ground and began refining chakra.

The Life Potion was indeed highly effective. As soon as Li began refining chakra, the cells throughout his body sprang to life, rapidly combining with his spiritual energy. Little by little, chakra was produced and flowed to his dantian. As the cells were depleted through the process, the Life Potion quickly restored them. By the time the potion's effects had worn off, Li had refined enough chakra to reach elite Genin level. Yet he didn't stop. He continued refining, having just sensed that he was on the verge of breaking through to Chunin. This was an opportunity.

Li's spiritual power was immense. As a member of the Uchiha Clan, he had been born with powerful spiritual energy. On top of that, he retained the memories of his past life, giving him spiritual power that surpassed nearly every Uchiha. As for his physical energy, the Life Potion had already laid the groundwork, and now he could add the cellular energy he naturally possessed. Breaking through to Chunin was not impossible.

The cells in his body leaped with energy, and his spiritual energy joined with them like an invisible force. Pure chakra was refined, one surge after another. After a while, Li opened his eyes, a trace of delight on his face. He had succeeded. Feeling the chakra in his body multiply several times over, Li let out a slight breath. Chunin-level chakra really was far greater than that of an elite Genin. Without taking more time to savor this strength, Li quickly grabbed the bottle of Life Potion he had started earlier and drank the rest in one go. The warm sensation returned, and the cells depleted from refining chakra were instantly replenished.

Refining such a vast amount of chakra at the age of six would leave him with many hidden injuries in the future without the Sage Body to support him. It was the same with Itachi Uchiha. Although he was hailed as a genius, he had awakened the Mangekyō Sharingan too early and pushed himself too hard while refining chakra during training. Though this gave him exceptional strength, his body was also crushed by the Mangekyō Sharingan and excessive chakra refinement. But now, with the Life Potion, Li no longer had to worry about over-refining his chakra.

After reaching Chunin-level chakra, Li stood and brushed the dust from his clothes. He was just about to leave when a shinobi from the Uchiha Clan suddenly appeared in front of him.

"Mirai Uchiha, the clan head wants you to come see him!"

As soon as the shinobi finished speaking, he disappeared, showing no regard for the Uchiha Clan's young genius. Li had seen him before. He was one of Uchiha Hao's trusted aides, one of the twenty Jonin in the Uchiha Clan, and a man of considerable standing within the clan. Then again, every Jonin held a high position. In all of Konoha, there were only around a hundred Jonin in the open, and fewer than thirty elite Jonin. The Uchiha Clan's Jonin accounted for only twenty percent of Konoha's total.

"With strength like that, they think they can resist Konoha? No wonder they get wiped out later on!" Li shook his head slightly and pushed the sudden thought aside. Uchiha Hao had summoned him, and it probably wasn't for anything good. He'd better go see what he wanted first.

When Li arrived at Uchiha Hao's study, the clan head was already waiting beside his desk with his hands clasped behind his back. Li gave a slight bow and said, "Clan Head!"

"Mm, Li, I just went to speak with the Third Hokage. I'm planning to have you take the Genin exam tomorrow. If you pass, you can become a Genin right away. You're already six years old, and with your talent and strength, you should have no trouble becoming a Genin. The Military Police Force is short-staffed, so once you become a Genin, report there directly. I'll arrange a job for you." Uchiha Hao's voice was calm. Clearly, he had spent some time thinking this over.
