"Xiao Pan, I'm not afraid of you laughing at me, but our Doudou has been ill for many years. I tried everything but couldn't cure it. I didn't expect that you solved it with just one move. I really want to thank you on behalf of our whole family!" Grandpa Wang said excitedly, holding Pan Han's hands.

"Uncle Wang, you're too polite. I happen to have a secret recipe at home, so it's unreasonable for me to just stand by and watch someone die."

"It's just..." Old Master Wang changed the subject and frowned.

Pan Han and Wang Doudou didn't know what he was up to and looked at him nervously.

"It's just that medicine is always toxic, especially this folk remedy of yours, which is so effective. I'm worried about any side effects. So, could you please hand over the prescription or make another one for me? I'll take it for testing and examination."

Mr. Wang's eyes were sincere, his tone was firm, and his words were flawless.

Pan Han was not surprised when he heard this. After all, what else could they ask him to do besides ask for treatment and medicine?

However, friendship is friendship, and business is business. Handing over the potion unconditionally is impossible. He needs to ask for some conditions, otherwise it will seem like a fake.

Wang Doudou was not surprised, after all, her father had informed her in advance.

Seeing Pan Han's hesitation, Old Man Wang wasn't surprised. After all, it was a family secret recipe, and anyone would have had their own concerns about giving it to a pharmaceutical company. However, he had a lot of conditions, so he wasn't afraid of not being able to satisfy Pan Han.

I'm not afraid of you making conditions, I'm just afraid of you not making any!

"Well, Uncle Wang, this may not be easy to handle." Pan Han looked troubled.

"Look, here he comes." Old Master Wang knew Pan Han did it on purpose as soon as he heard it. This kid is indeed a person who won't release the eagle until he sees the rabbit.

"Oh? What do you mean?"

"This recipe has been passed down in our family for hundreds of years. It's always been passed down within the family, never to outsiders, and passed down to sons, never to daughters. I can't break our ancestral rules!"

Wang Doudou couldn't help but chuckle when he heard Pan Han bring up his ancestors. He thought, this kid is telling the truth.

"Well, we have rules at home, which is understandable. But I'm afraid Doudou will have sequelae, so I'd better test the ingredients before I can feel at ease." Old Master Wang was very embarrassed.

"Uncle Wang, Doudou. This prescription actually has a story behind it." Pan Han kept the secret.

"Oh?" The two of them became interested when they heard it.

Pan Han's mind was racing. He had to make up a good story to get money from the capitalists.

"This story started 300 years ago." Pan Han told the story he had just made up.

Mr. Wang thought to himself that this guy is an expert!

"Back then, there were four waves of conflict and chaos. Although my ancestral village wasn't directly affected by the flames of war, many refugees fled here."

"Among this group of refugees, there was a Taoist priest. Because his Taoist temple was in ruins, he had no choice but to become a refugee. He followed the group and came to the village."

"At that time, my ancestor was the village doctor. So, we were worried that the refugees would bring infectious diseases. The village chief asked him to check everyone. The check was not serious, but he discovered a shocking secret about the Taoist priest."

Pan Han paused here, and seeing that Mr. Wang and Wang Doudou were both listening patiently, he continued.

"At that time, the Taoist priest hadn't eaten for several days. He was so hungry that his chest was sticking to his back and he didn't even have the strength to speak. Seeing his condition, my ancestor fed him some rice porridge. After his complexion stabilized, he took his pulse."

"As a result, our ancestors discovered that this Taoist's pulse was so chaotic that they had never seen such a disorder in their many years of medical practice."

Old Master Wang listened with great interest and couldn't help but pour water for Pan Han.

After taking a sip, Pan Han continued, "When our ancestors saw the Taoist's pulse was so disordered, they quickly asked what was going on."

"The Taoist priest gave a bitter laugh and told my ancestors not to waste their efforts, as their time was numbered. He had already lived for a few extra decades in vain, and had earned enough money to cover his losses."

"Ah? There is such a magical thing?" Wang Doudou didn't know whether what he said was true or not, and was completely immersed in the story.

"Yes, my ancestors were also puzzled and asked the Taoist priest why he said that."

"The Taoist priest quietly told my ancestor not to tell anyone else. My ancestor knew he didn't want others to know the secret, so he took him home and found a separate room in the side room."

"Who knew that after the Taoist priest entered the side room, his condition worsened. He kept coughing, and my ancestor hurried to get him some cough medicine. But the Taoist priest grabbed my ancestor and said it was useless, saying that his time had come."

"Our ancestors knew that some practitioners could predict their own death in advance. But they still went forward to comfort the Taoist priest. The Taoist priest said that he had a body of the Five Supremes and should have died suddenly at the age of 18. However, by chance he entered the Taoist temple. The master took pity on him and gave him a pill every year, asking him to swallow it, saying that it would prolong his life."

"Ah? Is there really an elixir in this world?" Wang Doudou couldn't help but exclaim when he heard this.

"Don't interrupt Xiao Pan, let him finish." Old Master Wang comforted Wang Doudou.

"In this way, the Taoist priest took a pill every year and extended his life for another 18 years. Later, the Taoist master passed away and left the pill recipe before his death. He asked the Taoist priest to prepare it himself. After the Taoist priest got the recipe, he extended his life for another 18 years." Pan Han took a sip of water and continued.

"The Taoist priest was coughing non-stop and was even coughing up blood. Seeing that he didn't have much time left, he quickly took out the elixir formula and gave it to my ancestor. He said that he and my ancestor had a connection and that this elixir formula could save lives and shouldn't be abandoned by a dying person. He asked my ancestor to use it well and heal illnesses and save lives."

"My ancestor, holding the elixir formula, felt a great sense of responsibility and quickly agreed to the Taoist priest's request. As soon as he finished speaking, the Taoist priest vomited blood and died. After burying the Taoist priest, my ancestor began to delve into the elixir formula. Unexpectedly, this elixir formula also contained a huge secret."
