"Uh?" Seeing the visitor, Tianyi was also stunned. Isn't this the little magician he just taught yesterday?

"Haha, it's a coincidence. I didn't expect that this old man was your grandfather. I came here to buy medicine."

"Are you Lan Duo's new coach?" Hearing the conversation between the two, the old man who was originally confronting Tianyi also reacted and looked at him with an incredible look on his face.

"You portrayed the magic circle in the spiritual realm of Landuo?"

"Yes, it's me." Tian nodded and looked at the student he just accepted yesterday.

Among the five students, there was only this girl and this magician. She should be the youngest among the five, so Tianyi remembered it very clearly. The girl's blue eyes and blue hair, and her body was filled with a cool breath. Although her face was not as beautiful as Xia Qiaona, she was very lively and cute. Even when she didn't smile, she had two dimples on her face.

However, at this time, the girl's cute face was a little tired - the magic circles engraved into her spiritual realm were operating at all times, and she would not stop even when she was sleeping. This made the girl who had just undergone high-intensity training for a day look a little overwhelmed.

"Yesterday, my granddaughter said that her new coach was a young man, so powerful that he not only defeated five of them in an instant, but also used the attack method they were best at. At first, I didn't believe it, but after seeing the magic circle you portrayed into her spiritual realm, I truly believed it!" After learning about Tianyi's identity, the old man's eyes showed no unconcealed appreciation.

"Your magic array is portrayed perfectly. Your understanding of magic array and micro-control of magic elements have reached the pinnacle! But..." The old man praised, but suddenly changed his expression: "But do you know how dangerous it is to portray magic arrays in other people's spiritual realms? If one is not good, it will completely destroy the person's mental system. At the least, it will be dementia, and at the worst, it will be directly dying!"

"It's okay, don't worry. I'm not sure that I won't do this!" Tian Yi smiled slightly, explained, while his index fingers of both hands shone slightly and danced in the air.

After the blink of an eye, a gorgeous magic circle appeared in the air out of thin air.

"This...is this?" Seeing the gorgeous magic circle suddenly appearing in the air, the old man's angry expression was fixed on the spot.

"This is the legendary empty array diagram!" Lan Duo covered his little mouth in surprise.

"Yes, the air array diagram does not require any medium. The magic elements are used directly to form a magic array in the air. The ability to control the magic elements needs to reach a very, very high level before it can be completed." After carving the magic array, Tian Yi hooked his index finger, and the various medicinal powders in the distance floated into this magic array. Then his hands emitted the energy of various magic elements like dancing, and returned the medicinal materials to various positions in the magic array.

"Look at the old man, this is the real method of refining young potions. I will only demonstrate once." Tian Yi smiled slightly, and before he finished speaking, the magic circle emitted a faint but colorful light. His whole person completely turned into a part of the magic element, and combined with the surrounding fluctuations to create a perfect rhythm.

"So beautiful!" Seeing the colorful light flashing in the sky array map and the charm of Tianyi's refining level that had reached the artistic realm, Lan Duo was obsessed with the spot.

After a moment.

With a bang - a ball of liquid emitting crystal light appeared in the air. Small particles shining like stars in the liquid blue, and the entire potion was as beautiful as the stars fell into the sea.

After taking an empty bottle of potion, Tian Yi put the beautiful ball of liquid in it and handed it to the old man who was still stunned.

"Try the effect?"

"Uh..." He took the potion tremblingly, and the old man took an obsessive look at the things in the bottle, and then drank it without hesitation.

Gudu Gudu... As the sound of his swallowing gradually became stronger, Lan Duo was surprised to find that his grandfather's head had returned to light blue at a speed visible to the naked eye, and the lines of the ravines on his face became sparse and smooth as if time had flowed back. After a while, when he put down the empty bottle in his hand, a middle-aged man who seemed to be in his fifties appeared there.

"It's amazing, grandpa, you're almost the same as dad!" As if you can't believe it, Lan Duo walked up to the old man and squeezed his face with his hands.

"So flexible, grandpa, you don't look like a person in your seventies or eighties now." Lan Duo jumped up in surprise, clapping his hands and dancing, "It's so amazing, so amazing! I've never seen such a magical potion!"

"I didn't expect there was really a young potion in this world." The old man who had already turned into a middle-aged man said to Tianyi in an almost admiring tone: "Good skills, clever skills! When I got this news from the 'spokeweb', I just bought the prescription with a try-and-see attitude. And because the prescription is incomplete, I didn't plan to make it into finished products to sell. I didn't expect you to have a complete prescription here. Where did you get it?"

"He invented this prescription from an old friend." Tianyi stretched out his hand and pointed it slightly in the air. The empty array diagram that had lost the support of magic elements turned into streams of light and collapsed.

"Your friend invented it?" The old man felt puzzled again.

"Yes, that's a very narcissistic guy!" Tianyi thought of the elf prince who fought side by side with him eight thousand years ago, and sighed and said, "Oh, it's a pity that he's already a half-dead person."

Just as I recalled the past, the old man who had just become young suddenly bowed deeply to him.

"What are you doing?" His actions successfully diverted Tianyi's attention. He looked at the old man who bowed deeply in surprise.

"I want to worship you as my teacher." As he said that, the old man bowed again.

"Hahaha, you're quite straightforward!" Tianyi laughed loudly. He had accepted many apprentices in his life, but it was rare to be so straightforward. Therefore, he was determined to accept this old man who seemed to him just a "child".

"Don't you think I'm young?" Tian Yi smiled.

"The master is the teacher, and the master is the first! I don't care about your age. Whether you are ten thousand years old or twenty years old, as long as you are better than me, you can become a disciple." When I said this, the old man's eyes were unprecedentedly firm.

"Okay, okay, okay! A good master comes first!!! I like your argument and your spirit." Tian nodded, "As long as you stick to this spirit, your future achievements in the field of medicine will be higher than you imagined!"

"Thank you." The old man grinned.

"May I have your name?"

"Lan Feng!"

"Okay, from today on, you will be my disciple. If you have any questions in the future, just ask me." Tianyi found a quill and wrote a herb recipe as he spoke.

"This is the formula of a young potion. With your basic skills in refining, it should be able to be successfully refined." After Tianyi handed the formula to Lan Feng, he continued: "You should know what this prescription means. Haha, although it cannot really increase lifespan, there should be nothing more attractive to women than youth and youth. I believe that those noble ladies will spend all their money to buy this kind of potion!"

"I will give you the prescription. We will earn half of your income in the future. I need money now!"

"Okay, thank you, Master." Lan Feng, who had been living for seventy or eighty years, certainly knew how much wealth this prescription meant.

"But now grandpa and I have worshipped the same master, and it's not easy to get along with their seniority!" Seeing that grandpa actually worshipped the coach as his teacher, Lan Duo grabbed his head and said.

"It's okay, you call you, he calls him, it's okay." Tianyi spread his hands, "I have encountered many situations in this way, and there is nothing to deal with."

Tianyi vaguely remembered that he had met a wealthy martial arts family in which all the eight generations of ancestors and grandchildren worshipped him as his master, but they were all called their own, otherwise it would be really bad if they counted as seniority.

"If there is nothing else now, you can follow this prescription and get me six medicinal herbs." After solving the errands, Tianyi finally brought the topic to the right track.

"Okay, Master, wait a moment." Finally, she took the list of medicinal materials. This time, Lan Feng respectfully grabbed all the medicinal materials he needed for Tianyi.

Tianyi refines medicine on the spot, and while explaining to Lan Feng, he refines a total of six bottles of "system medicine".

After seeing the process of Tianyi's practice of physical medicine, Lan Feng was even more impressed by his new master. His rich knowledge of refining and perfection completely overturned all his previous learnings.

"Here, I'll give it to you." After refining the potion, Tianyi handed Lan Duo a portion.

"It turns out that the coach refines medicine for the sake of the five of us!"

"Haha, drink it quickly, who else can you do if you are not for you?" Tianyi smiled slightly, "This kind of thing has no effect on me."

After taking the medicine, Lan Duo gave Tianyi a thankful smile, and then slowly drank the bottle of light blue medicine.

After drinking the medicine, Lan Duo did not change much on the surface. However, after putting down the medicine bottle, her eyes suddenly became painful, and then black beads of sweat appeared on her forehead.

Gugu~~~!

An indecent sound then rang out in the air.

"Coach, I'll be with you for a while!" Lan Duo's face turned red, he stomped his feet and rushed towards the back door of the store.

"Don't worry, this is the detoxification period." Tianyi looked at Lan Feng's worried face and said, "When she eliminates all the impurities in her body, her body will be purer, and then her physique will gradually become stronger. By the way, this is the medicinal material money just now..."

"No, Master, how can I ask for your money?" Seeing Tianyi taking out the magic crystal card, Lan Feng waved his hand quickly and used a respectful word to speak: "Besides, aren't there a portion of the medicine here for my granddaughter? And the medicinal ingredients recipe just now, that's something that's priceless. What are my medicinal ingredients!"

"Okay, since that's the case, I won't pretend to be generous with other people's money. I still have something to do, so I'll take a step first."

Before he finished speaking, Tianyi walked out of this huge refining hall.

"Lan Feng, remember to make money well. I will come back to collect the accounts in a while." With Tian Yi's figure, he left with his last sentence before leaving.

Seeing Tianyi being thunderous and decisive, Lan Feng hurried out to welcome him and see him off. When he walked out of the store, he found that Tianyi had already reached the end of the street at some point.

"Master, don't worry, I will make money well." Lan Feng shouted loudly at the back of the street.

His shout also attracted the attention of several shopkeepers in the surrounding shops. Then, there was a large number of discussion.

"Who is that at the door of the Lan family store? Is that a young master? Is that Lan Feng's son? Why do you look so similar to him?" Old Li from the weapons store asked the guy next to him.

"It must not be. I have seen Lan Feng's son, it's not like this." The guy shook his head, "But his son is not as good as Lan Feng as he is. Isn't this his illegitimate son?"

"Hey, over there, who is Lan Feng, why do you look so similar to that old man?" A shopkeeper who looked very close to Lan Feng stood in front of the shop door and shouted.
