While Nami is still young, invite her to join my ship!

According to this learning efficiency.

Ning Chuan finished learning all the books that Kulokas gave him in less than three hours.

When Ning Chuan put down the last book, Kulokas was speechless with shock at Ning Chuan's learning efficiency.

He had never seen anyone with such efficient learning ability.

It was as if Ning Chuan was born to be a genius for medicine!

Kulokas swallowed in shock.

He asked a few difficult questions in disbelief for verification.

As a result, Ning Chuan answered all of them fluently.

This made Kulokas have to admit.

Ning Chuan had indeed memorized all the books in that pile.

He had successfully entered the door of medicine.

He could learn more in-depth content from him.

"This kid is really a genius!"

Kulokas couldn't help but sigh.

He turned his head to look at Ning Chuan, hesitated for a moment and then spoke.

"Since you have already mastered the basics, then prepare to learn pharmacy, which I am best at."

As soon as the voice fell.

Kurokas returned to his lighthouse cabin.

He brought out a large category of books related to pharmacy for Ningchuan.

Such as "The Great Line Animal and Plant Encyclopedia", "The Great Line Drug Application and Efficacy Summary", "Basic Proportion Scheme of Pharmacy"...

Looking at these precious books that Kurokas brought out.

Ningchuan did not hesitate at all and took them all.

Because he knew that if he wanted to learn pharmacy well, he had to know all the drugs.

Ningchuan flipped through the books in his hand one by one.

Constantly using the power of the system to strengthen the knowledge he had learned.

Until all this knowledge was deeply rooted in his mind.

Time passed quickly.

In the blink of an eye.

Ningchuan had learned from day to night.

Even when eating, Nokigo and Nami took turns feeding him.

Looking at Ning Chuan who has such perseverance.

Kurokas on the side couldn't help but admire in his heart.

"This kid is amazing!"

"So smart and talented, and so hardworking."

"It's really rare!"

After sighing, Kurokas returned to his hut.

He once again brought out a large stack of books.

He wanted to see how amazing Ning Chuan's learning speed could be!

It wasn't until the next morning, when the sun climbed above the horizon.

Ning Chuan finally finished learning all the books, research notes and general potion formulas that Kurokas took out!

When he closed the last book.

Ning Chuan felt that he should have become an excellent potion master now.

"You, you have learned all these things?"

Looking at Ning Chuan who stood up and did Kun Quan to exercise his body.

Kurokas exclaimed in disbelief!

"I've finished learning!"

"I have to say, pharmacy is really profound!"

"Mr. Kurokas, I admire your research!"

Looking at Ning Chuan's relaxed look at this time.

Kurokas couldn't help swallowing his saliva.

"Good guy!"

"My research on pharmacy for decades was mastered by this kid in one night?"

"What a joke!"

Although Kurokas couldn't believe it in his heart.

But he didn't think of testing Ning Chuan.

After all, he had experienced the attitude change from doubt to shock several times before.

Kurokas is now a little numb.

"You kid, you are really perverted!"

Kurokas shook his head helplessly.

Then, he reached his hand to his waist and took out two yellowed pieces of paper.

There were densely written small words on these two yellowed pieces of paper.

Ning Chuan took a quick look and judged that the recipes of two potions were recorded on them.

"These two formulas are my specialties."

"I didn't plan to teach you, but I thought it would be a waste for me to keep them, so I'd better let you take a look."

"If you can improve on these two prescriptions, it would be great!"

Kurokas shook his head helplessly.

Finally, he began to explain to Ning Chuan what the two formulas were used for.

"This formula is the medicine I used on Roger at that time."

"It can make him ignore the pain in his body temporarily and maintain the best condition until he dies."

"But unfortunately, such a prescription has a great side effect, which is that it will further aggravate his virus and reduce his survival time."

Ning Chuan took the prescription from Kurokas in his hand.

He roughly browsed through it.With his current status as a master of medicine.

It is not difficult to see the efficacy and side effects of such a prescription.

"If Roger doesn't take this medicine, he should be able to live twice as long."

"However, his condition may be much worse."

Ning Chuan looked at the prescription and thought for a moment, and gave his own analysis.

Kulokas heard Ning Chuan's guess and couldn't help but look at him more.

Because Ning Chuan's analysis was quite right!

"He can analyze so many things by just looking at the prescription. I'm afraid this kid has become a master of medicine, right?"

"What an incredible kid!"

Kulokas sighed in his heart.

After introducing the first prescription.

Kulokas set his sights on another prescription in his hand.

But when he looked at the other prescription in his hand.

Kulokas rarely showed a hint of excitement in his eyes.

"This second potion formula I'm going to teach you is a body strengthening formula, and it's the last one I've researched!"

"Because it has too high requirements, it must be taken by young people who are no older than 15 years old, and no one has really used it yet."

Speaking of this, Kurokas looked at Ningchuan excitedly and said.

"After using this potion, the user's physical strength and injury recovery speed can be continuously improved in the next few decades!"

"Especially after experiencing a lot of battles, its efficacy will be further exerted!"

Speaking of this, Kurokas suddenly stopped.

He looked at Ningchuan helplessly, and then shook his head.

"Although this prescription is strong, the cost is that life span may be greatly affected!"

After listening to Kurokas's narration.

Ningchuan directly gave his own analysis.

"So, its principle is to rely on constantly squeezing people's potential to make people quickly stronger, right?"

Kurokas did not answer, but just nodded silently.

"I have put all my life's learning into this prescription."

"But I can't think of how to improve it further."

After hesitating for a moment, Crocus put the prescription in Ningchuan's hand.

"There is a medicine laboratory I set up in the lighthouse, and the materials needed for medicine experiments are basically all there."

"If you have an idea, you can try it."

Ningchuan took the formula, studied it carefully for a while, and had a plan in mind.

He looked at Nami and the others, thinking that if this potion could be improved and the side effects removed.

Maybe it can help Nami and the others improve their strength quickly.

Although Nami and the others didn't say anything about their own strength.

But Ningchuan knew that they actually wanted to become stronger and help him.

There are many ways to become stronger, such as devil fruits or hard practice.

But Ningchuan didn't want them to eat the devil fruit.

After all, if you eat the devil fruit, you will be afraid of sea water, which is a fatal weakness!

But if you work hard to practice, Nami and the others are too young now.

The speed of cultivation will not be too fast, which is also a big problem.

But now, the new medicine that Kurokas brought out.

It is a good way for Ningchuan to help them become stronger quickly!

"Eliminate the side effects of the medicine?"

"Then we must study it more!"
