"Wow, why do you want so many materials? What are you planning to make?"

Hou Jie looked at the dense list of materials and was shocked.

The list even had some materials that she did not even know. If she was not aware of this student's strength, she would suspect that he had deliberately written these to mess with her.

"I'm going to make an exclusive energy potion for my pet. I plan to use cheaper stuff because of the tight budget, so there are a few more materials."

Su Bai explained.

"Are you sure that you can do it? You must know: If your pet takes the wrong energy potion, it can lead to serious consequences."

She warned him, afraid that he would become arrogant and ruin his godly pet.

"Teacher, don't worry; I'm pretty confident. Also, I certainly won't directly feed it to my pet."

Su Bai assured, knowing that, with information on these things provided by his Pet Tamer interface, they would not have a problem.

Still, he was extremely grateful for the older lady's concern and felt really fortunate to have such an English teacher.

Hou Jie did not stop him and just thought that perhaps this was the world of a genius. "Wait, I'll find these for you. Some materials may not be available in the store, so I'll need to buy them outside."

Not long after, the teacher returned with a bunch of stuff and sighed. "These were really difficult to find. If not for my brother doing research and having lots of materials, I wouldn't be able to gather them everything at all.

"Still, there are few of the black poisonous fruit, and in fact I've only got thirteen of it. It may be unavailable for a while."

"It's alright. Thirteen is enough."

Su Bai nudged the cub.

While the black poisonous fruit was not very useful, it was still a rare spiritual fruit as the fruit contained a very faint hint of profound wood.

The black poisonous fruit was the main ingredient of his medicine, with the key to the concoction being the extracted profound wood and the strong toxins of the fruit.

This profound wood was weak by itself, but once combined with the fruit's strong toxins, it became a relatively rare yet inexpensive medicinal property.

He had requested so many materials mainly for the extraction of profound wood.

"Student, can I watch from the side?" asked Hou Jie. She was still curious about what Su Bai would do with the large pile of materials.

"Of course." Although this was a new medicine formula, it was exclusive to Purple Jade and would not have a particularly obvious effect on other pets.

In addition, with his English teacher around, he could ask for her help.

With her help and her Polyursus—that bear-type monster with a body made of tiny fungus, it was much easier to make the potion.

Su Bai first started on the medicinal cakes, which were not as effective as actual medicines but tasted delicious and smelled nice.

In any case, these were aimed at special training, such replenishing energy or restoring spiritual power. Antidote medicinal cakes specialized in detoxification, while the strength medicinal cakes specialized in increasing stamina.

He mainly made the green energy medicinal cakes, which specialized in restoring the cub's spiritual power and relieving its gluttony. He also made a few other types of medicinal cakes.

Making medicinal cakes was a handicraft. The materials must not only be decomposed but also needed to maintain their characteristics yet not their taste; meanwhile, others had the opposite concocting requirements.

The substrate of an green energy medicinal cake was the wood spirit crystal, which he ground into powder for later use. The orange fruit was then beaten into juice for later use. Finally, he processed the other materials and matched them according to certain proportions and put all into the automatic production machine .

A few minutes later, a layer of fifty orange-flavored green energy medicinal cakes was completed.

Su Bai went to make energy medicinal cakes with cream, grapes, red dates, and dried fish, all of which being the cub's favorites.

After the production, he became familiar with how to operate the equipment in this cultivation house and began making an exclusion energy potion, 'No. 1 Purple Jade', for the cub.

"Teacher, can you help me break down these materials?" He started making use of her.

"Of course." Hou Jie walked over to help.

Although No. 1 Purple Jade required a lot of materials, its key ingredient was the preserved and fixed profound wood of the black poisonous fruit. Its other effects were basic recovery of spiritual power and increment of stamina.

As long as it had the profound wood, its efficacy would more than double a dozen times.

After all the materials had decomposed and were dissolved, he began making the medicine.

He first siphoned the components of the materials via an extraction method, then filtered and distilled some spiritual solutions. Some components could not be extracted through conventional means, so he had to rely on a special method for successful extraction.

The scientific development in this area had been greatly improved over the past one hundred years, so most materials could be extracted with relevant instruments.

After completing the extraction process, Su Bai moved to the most intense and exciting stage: blending. It was very much like a chemical experiment and had to be handled with care and done very precisely.

He poured three millimeters of the spiritual grass essense into the fruit extract, then he shook the mixture gently. The solution directly turned a light green shade.

...

Half an hour later, only two cups of solution could be seen before Su Bai. One cup was the black poisonous fruit filtrate, which had turned a dark green shade, that he had just made. Another cup was the mixture, which looked transparent just like water, made of other materials.

He took a fixed amount of the mixed liquid, poured it into the black poisonous fruit filtrate, and gently stirred everything with a glass rod.

As the two blended with each other, the color of the entire solution changed from dark green and purple-red until finally to bright purple. Only the center of the beaker was suspended with a thin, dark green incomplete spiral, which resembled a strand of hair.

This spiral was only about two or three millimeters long, and it was the fixed profound wood in the black poisonous fruit.

"Success!"

Su Bai heaved a sigh of relief. Although he knew the specific formula thanks to his pet interface, it was still very difficult to put in practice. Fortunately, the school offered pharmacy classes, so he had some basic knowledge.

"That… is a strand of profound wood?" Hou Jie looked at the tiny, dark green, chain-like spiral.

"Yes, it's profound wood from the black poisonous fruit. On top of studying the principle myself, my pharmacy teacher once explained it, too. Mainly, I learned the method of concoction from the market." He nodded.

"Okay."

His teacher did not know what else to say. Sure enough, they were of different breeds of human. She could not accomplish this even if she were at the peak of her passion.

Many people knew the principle, but being able to use it to develop a new method was definitely proof that one was a master pharmacist.

After completing the preliminary production, Su Bai was more familiar with the machine and it was not so troublesome anymore.

Since he only had thirteen of the black poisonous fruit, he made thirteen bottles for the time being.

"By the way, teacher, how much do these materials add up to?" he asked.

"I'll give you a discount; you can give me a total of 200,000 yuan," replied his teacher.

Upon hearing his question, Hou Jie suddenly understood that, despite being a genius, the boy was truly still her student and worked under her. She suddenly did not feel so depressed anymore.

"Thank you, teacher." Su Bai thanked the woman sincerely.

The market price of one hundred energy medicinal cakes, plus thirteen bottles of medicinal ingredients, was at least 250,000 yuan, so she had indeed given him a big discount.

These energy potions and energy medicinal cakes were almost enough to feed the cub for a month.

Each energy potion contained incomplete profound wood. The cub's body needed about three days to digest it. This was unlike the previous wood spiritual potion, which only required one bottle a day.
