Ten minutes later, Yan Xiao, who was originally fierce and full of energy, suddenly shook, and his breath quickly became weak, and his body was sweating profusely.

"How is it? Do you feel that there is something wrong?" Sarutobi Hina asked quickly.

"Only one-tenth of the chakra is left, and his physical strength has been exhausted and he has recovered slowly." Yan Xiao's hoarse voice came from under the mask, as if he was a little difficult to speak.

"Is it just that chakra and physical strength exhausted?" Sarutobi Hinako murmured.

"He didn't fight just now, and I guess he will recover in one or two days." Sarutobi Tsuki interrupted at this time.

Sarutobi Hinashen waved his hand, and another nanbu appeared in the room.

"Feng Yan, you escort Yan Xiao back. Yan Xiao, this time you will complete a B-level mission. You will take a vacation in the next three days. Let's report it again in three days!"

"In addition, today's matters are included in the confidentiality and are strictly prohibited from leaking them!"

"Hi" the two agreed, and Feng Yan took Yan Xiao away from the house.

Seeing that even Anbu had left, Sarutobi Hinako's face showed excitement, "Is this kind of potion difficult to make?"

"It's not too difficult. The cost is about 100,000 taels. Large-scale production can reduce the cost. I spent about one million taels to develop the potion. Tsunade and I were all paying for pocket money. Don't forget to reimburse me!"

"Don't worry, don't say one million taels, ten million taels are fine. I will calculate an S-level task for you, and I will add it to your resume when you graduate." Sarutobi Hinata said happily.

The cost of 100,000 taels is not a small amount, but the ninja profession is at a high risk and also has a high income. Any Zhongnin can easily take out this money, even a Xianin, and you can pay this money after accumulating for a few years.

The increase in combat power of this potion is that the stronger the strength, the higher the improvement. During the onset of effect, the combat power is almost completely improved by one level. The lower ninja reaches the middle ninja, and the middle ninja is increased to the upper ninja, and the upper ninja can compete with him, the Naruto.

Although there is only ten minutes to start, for a ninja, a crisp profession with high attack and low defense, ten minutes is enough to distinguish life and death.

After all, there are not many blood bulls like the third generation of thunder shadow that can fight for three days and three nights.

It can be said that this potion has almost improved Konoha's combat effectiveness by more than 30%.

"It is best not to popularize the drug into the Shinin to maintain their fighting spirit. It is also best not to use it if you are too young and under 16, as it will damage your future potential."

The smile on Sarutobi Hinako's face was restrained. Indeed, false strength can easily make people lose their will to fight. As for damaging the potential of young people, this is something he had never thought about.

There are many things in the Naruto world that can destroy potential and fight power, and no one in the whole world thinks there is anything wrong with this, but in Sarutobi Shiro's view, this behavior is completely killing the chicken and getting the eggs, and it is extremely stupid.

Especially in the Ninja Village, they also advocate geniuses who graduate early every day. As a result, they often overdraw their physical potential when they were young, but in the end they made slow progress and were difficult to become a great man when they reached their peak.

Sarutobi Shiro can't control the whole world's atmosphere now, but it's okay to remind his uncle.

If he hadn't known that there would be no war for at least ten years in the future, he wouldn't have been willing to graduate early!

"Okay, I will forbid Shinin and ninjas under the age of sixteen to use potions." Sarutobi Hinata said seriously.

The corners of Sarutobi's mouth were raised, "In fact, there is no need to ban Shinin from using it. Just increase the price and make Shinin unable to afford it!"

Sarutobi Hinako's eyes lit up, but he said righteously: "How can you exploit Konoha's compatriots? Konoha ninjas are all family!"

"But you can't just consider the cost of making medicines, labor costs and R&D costs should also be considered."

Well, this cheeky look is no wonder that he can be a Naruto!

After talking about super adrenaline, Sarutobi Hizawa picked up the blue pill again and asked, "What's the purpose of this? Will it restore chakra?"

"Oh, this is an aphrodisiac."

"Uh~ I didn't hear clearly. What kind of medicine is this? Is it the medicine for sturdying Yang Dun Chakra?"

"Powering ~ Yang~ medicine~! The kind of medicine that can make men go seven times a night!"

Sarutobi Hinazo's expression became indescribable. Finally, he looked at his nephew speechlessly and asked, "Do you use aphrodisiacs as a research result?"

Sarutobi snorted coldly and spoke to his inexplicable Uncle Naruto, "The cost of the pills in your hand is no more than ten taels, but if its effects are transmitted, it will increase by ten times the price, and the supply will still be in short supply. In the future, the business of selling medicines will be worth 30% of Konoha's fund!"

Sarutobi Hinata looked disbelief and had never seen the super high profits of the blue pill on the earth. Of course, he didn't believe in such a thing.

However, Sarutobi Toru was full of confidence. This special pill made not only has the effect not less than the blue pill on earth, but also has the effect of warming and tonic. It is definitely a life-saving blessing for middle-aged men.

Seeing his uncle's hesitant expression, Sarutobi Tsuki said, "If you don't believe it, you can try selling it first. If you can't sell it, I won't want the laboratory!"

"The laboratory will give you it's your super adrenaline enough to prove your ability. However, in the world of ninja, you haven't forgotten the most important thing!"

"Of course not." Sarutobi Shiro took out two pieces of white paper with words from his pocket and put them on the table. "This is a prescription, but don't wait to be beaten."

Sarutobi Hinazo nodded, leaving behind a sentence "Go to the training ground!" and disappeared from the spot.

Looking at the direction where his uncle disappeared, Sarutobi Shiro smiled slightly and immediately followed.

On the training ground, Sarutobi Hinashen threw it casually, and the Naruto robe hung on the wooden stake, revealing a neat ninja suit.

"Come on! Let me see how much you have grown over the past year!"

"You're good at Uncle Zhan that day. Don't blink your eyes."

When Sarutobi Shiro said blinking, his figure had already flashed directly in front of Sarutobi Hinako like a ghost, and Kuwu in his hand instantly stabbed Sarutobi Hinako's lower abdomen.

When Sarutobi Shiro was talking about his eyes, Sarutobi Shiro, who had been blocked by Kyuubi for three times, had already walked around the back of Sarutobi Hinako, but was kicked out by Sarutobi Hinako and forced him to retreat several steps.

When Sarutobi Shiro's eyes were spoken, he had suddenly returned to the front. Under the thorns of Kuwu, he forced Sarutobi Hiro to retreat three steps, and suddenly a bang turned into a wooden stake and disappeared in front of him.

When Sarutobi Shiro turned around, he saw Sarutobi Hizaki standing seven or eight meters behind him. He threw it away casually. Kyuwu turned into a sky full of Kuwuwu and flew towards Sarutobi Shiro.

"Fuck! I'm a ninja student, I'll use ninja skills!" Sarutobi Shiro cursed inwardly, and his body moved, and he had already retreated more than ten meters. At the same time, Kuwu was flying in his hand, and he turned into a shadow, shooting down several Kuwus, and finally escaped the wave of Kankawa clone technique.

Suddenly, Sarutobi felt his feet empty, and he was motivated without thinking. Two years of chakra control practice and Superman's speed played a role. He instantly escaped three meters, and saw that the ground was empty and he shrank back with one hand.
Chapter completed!
