Flying Thunder God of Douluo Continent

Chapter 61 Another year of autumn, another year of rest ([-])

Cao Bailu took the teacup on the side, took two sips of the tea in it, and waited for the questions from these geniuses.

The first to break the silence was a tall, thin young man with glasses.

"Hello, Teacher Cao, I would like to ask why the owner of a cat-type martial spirit should not absorb the spirit ring of a tiger-type spirit beast?"

"It stands to reason that soul ring types of the same class should be absorbed more easily,"

Cao Bailu looked at the thin and tall young man, and said, "The problem of suppression is mentioned on page 107 of your textbook, but you didn't go into details."

"Because tigers are the top-level existence of feline spirit beasts, they are born to suppress ordinary feline creatures. If a soul master with an ordinary cat spirit absorbs the spirit ring of tiger spirit beasts, not only will it not It will be easier to absorb, but it will be suppressed by the soul ring itself, this is the problem of suppression,"

"The root of the problem of suppression is mainly the problem of category. If your martial spirit is top-level enough, you can naturally ignore the problem of suppression and only consider the problem of compatibility,"

"do you understand?"

Cao Bailu asked.

"Yes, I see. Thank you, Teacher Cao," the young man suddenly understood, bowed to Cao Bailu, and thanked him.

"Okay, next question,"

The next question was asked by a strange man covered in bandages.

"Mr. Cao, hello,"

His voice was very hoarse, I don't know why.

"Hello, what's your question?"

"Among the healing potions, the ratio of Soul-Sorrowing Grass and Yingyao Flower is three to one. Why do the potions I make every time have such poor medicinal properties?"

"Students, if you have any questions in the future, please ask the teacher. Don't test the medicine yourself..." Cao Bailu looked at the man speechlessly, and understood why he was covered with bandages and why his voice was so hoarse.

"Our teacher has been transferred away for a long time, and I don't know who to ask," the classmate replied.

"Don't you classmates discuss with each other?" Cao Bailu waved at the classmate, gesturing him to come on stage.

"I have the best grades among all the students enrolled in Pharmacy, and I am their representative. If I don't know, no one will know." The man didn't know why Cao Bailu asked him to go up, but he obediently obeyed.

Cao Bailu took out a small amount of dozens of herbs from the prepared items column, and brought a crucible from the backstage.

"You prepare the healing potion on the spot, and let me see where the problem is," Cao Bailu said.

"Well," said the man in the bandage, taking the cauldron.

He carefully selected the raw materials, ground them into powder according to the most suitable ratio, and added the corresponding solutes to the most suitable solvent.

Every movement is as standard as in the textbook, and every weighing will minimize the error.

Cao Bailu watched the bandage man's process of making medicine, and thought of himself who was still working under the master a few years ago.

The medicine is ready, the perfect medicine.

No matter the color or fragrance, it is exactly the same as the best healing medicine on the market.

However, there is still no medicinal effect, and it is easy to make people hoarse.

"Teacher, I don't understand, what is my problem..." the man in the bandage said innocently, looking at the healing potion in his hand.

"You have a problem with the use of the Soul-Sorrowing Grass and the Yingyao Flower," Cao Bailu pointed out the problem.

"Eh? Teacher, no, the ratio of my soul-scaring grass and Yingyao flower is indeed maintained at three to one, and the error is within a reasonable range. Is there no reason?" The man in the bandage was a little puzzled.

"Then please repeat the experimental operation you just did,"

"I first grind the soul-sorrow grass into powder, then heat and concentrate the juice of Yingyao flower squeezed out in proportion to filter out the water and oxygen in it, and then pour the soul-sorrow grass powder into the juice, which is a healing potion The most critical step of production, I am very careful in every operation," the man said, very puzzled.

Cao Bailu took another sip of tea leisurely, deliberately whetting everyone's appetite.

"Who told you that the powder is poured into the juice of Yingyao flower? If you dilute the concentrated sulfuric acid, can you pour water into the concentrated sulfuric acid?"

The whole place was silent.

Laymen watch the excitement, while experts listen to the way.

You will never be able to believe how wonderful the expressions on the faces of this group of pharmacy students were.

"I rely on!!!!"

This was the only phrase left in the auditorium in unison before the group of pharmacy students rushed out of the auditorium to go to the laboratory.

What was left was the stunned crowd.

The man in the bandage on the stage was a little uncomfortable. After all, he was the representative of the selected school of pharmacy.

"Well, Teacher Cao, I'm sorry, this question has been holding them back for nearly a month, and they're all in a panic." The man in the bandage bowed solemnly to Cao Bailu, "Thank you, Teacher Cao, for your teaching!"

"I withdrew too!"

The man in the bandage also rushed out. . .

The rest of the people in the audience have not yet realized what happened.

They looked at the open door of the auditorium, at the empty seats around them, and at Cao Bailu.

Cao Bailu was also looking at them.

He smiled and said, "Next question."
