The room was filled with bottles and jars, emitting an unknown medicinal smell. On the table were paper and pens, as well as equipment for brewing medicine.

She walked to the table, picked up a piece of paper with writing on it, and looked at it.

"In June of the twelfth year of Kangping, the secret medicine was finally successfully replicated. I was so excited that I could hardly express it... With this medicine, people can become incredibly strong and do things that they never dared to imagine before... The side effects still need to be studied."

Su Wan did some quick calculations and realized that Jiang Yan had created a performance-enhancing drug nine years ago. However, he said it was a copy, meaning that the original version of the drug was not invented by him.

She put down the page and picked up a stack of papers. Some of them contained a lot of writing, seemingly about pharmacology. Among them, she found several records and organized them chronologically.

"In August of the thirteenth year of Kangping... we tried adding ingredients to the secret medicine... it should not be aggressive towards the holder of the Resurrection Pendant. However, if the dosage is exceeded, the holder may lose their mind."

"In September of the fourteenth year of Kangping, I was extremely depressed... Why did the test subjects die after eating chili peppers? It is necessary to collect their black blood for research... The equipment in the clinic can be used; it should not be discovered, right?"

"In January of the fifteenth year of Kangping, the first batch of secret medicine was used on blacksmiths, and it was indeed effective. The armor they forged was better than ordinary armor, but it was too heavy for most people to wear. However, it was a very suitable suit of armor for those who had taken the secret medicine... We will consider adding other functions later."

"June of the twentieth year of Kangping. Six years have passed, and we are about to overcome this hurdle. Why must we go to find the goddess? Let my younger brother Wenpei go instead. I must conquer this obstacle."

"On New Year's Eve of the 21st year of Kangping, it was a success! The only weakness of the secret medicine has been eliminated... Even if a limb is amputated, the bleeding can be stopped as long as the secret medicine is injected in time... Too much will still cause the patient to lose their mind, and women have a very low tolerance for the medicine... There are still some problems that cannot be solved in a short time."

Su Wan put down the paper, thinking, "No wonder Jiang Yan isn't afraid of capsaicin. He discovered the flaw in this stimulant seven years ago and has been trying to find a way to overcome it."

New Year's Eve coincided with the fierce battle between her and Wei Jingzhuo at Xiping Pass. Jiang Yan likely used the equipment and technology in the clinic to research and improve the secret medicine.

After looking through all the papers on the table, I couldn't find any further records.

There was a piece of paper on the wall, and she went over to look at it.

"In February of the twenty-first year of Kangping, the production of Type II was too small, and the shelf life was also very short, only two months... Carry a few with you, they can be used to save your life in an emergency. But am I worrying too much? Who would dare to harm a family of divine doctors?"

Below the paper was a shelf with a vial of potion on it. Unlike the deep red potions, this vial was crimson, like flame.

A surge of excitement swept through Su Wan's heart. As a medical student, she was not immune to such miraculous medicine.

She picked up the potion and put it in the pharmacy, intending to use various instruments to study it later. Perhaps she could discover the flaws in this improved potion. Jiang Yan had already become a monster, so what she did wouldn't count as stealing.

After searching for a long time, I still couldn't find the solution Jiang Shan mentioned.

Her gaze fell on a corner where a standing metal cabinet, entirely in a modern style, stood. She walked over and opened it. Inside, there were two rows of clips, seemingly for holding long, cylindrical objects. A metal cylinder was clipped onto one of the clips.

There was a piece of paper at the bottom of the cabinet, which she picked up.

"No matter how potent the secret drug is, it cannot withstand the beam of the defensive gun. If someone goes berserk after injecting the secret drug, use the defensive gun to shoot them."

She removed the metal cylinder from the clamp.

It felt cold and smooth to the touch, and very heavy, like a solid metal rod, or like an ancient musket with its wooden handle removed. There was a button at the end. She remembered that Xie Maoliang had used this to shoot at her and Wei Jingzhuo.

This is definitely not ancient technology, nor is it the technology of her time; it can only be a firearm from the future.

She gripped her defensive pistol.

In that case, research is unnecessary; all we need to do is take down Jiang Yan with a defensive gun.
