How did a street urchin from the film crew end up in a Northern Song Dynasty drama called "The

“This disease is caused by a virus, and its symptoms include papules and blisters on the body. Didn’t you see those dense blisters on his face?” Jin Shuai asked with a frown and a somewhat anxious tone.

The doctor looked puzzled and pressed on, asking, "What is a virus?"

Jin Shuai slapped his forehead helplessly and sighed, "Sigh! Even if I explained it to you, I'm afraid you wouldn't understand. By the way, do you have any Isatis root in your medicine box?"

The doctor looked bewildered again and asked, "What is Banlangen?"

Jin Shuai thought for a moment and then replied, "It has other names, such as indigo root, blue indigo root, big green root, etc. These are the only ones I can think of right now."

Upon hearing this, the doctor nodded in sudden understanding and said, "Oh, I see. I do have some Daqinggen (a type of medicinal herb), let me get it for you to see." After saying this, he turned around, took out a root from his medicine box, and walked towards Jin Shuai.

Seeing this, Jin Shuai quickly stopped him, saying, "Don't move it! Just throw it over here. Hmm... that's it. But, are the leaves still on it?" Jin Shuai looked down at the fallen Isatis root and asked the doctor.

The doctor shook his head and replied, "Those leaves are not very useful; they are usually only used for starting fires and cooking."

Jin Shuai couldn't help but curse, "Damn it... What a waste! What a pity~ Since that's the case, then quickly get ten Isatis root roots, add three bowls of water and boil them together to make a potion. Also, Wan'er, go and buy a pound of dog meat. If you really can't find dog meat, dog bones will do." As he spoke, Jin Shuai tossed a heavy money bag to Wan'er.

At this moment, the attendants finally finished their work, and the smoke that filled the courtyard gradually dissipated. After scanning the area, Jin Shuai instructed, "Everyone, please wash your hands thoroughly with yellow wine first."

Upon hearing this, the attendants couldn't help but show surprise and looked at Jin Shuai. One of them couldn't help but ask, "Handsome, why...why wash your hands with yellow wine?"

Jin Shuai frowned slightly and replied seriously, "Stop nagging! Just do as I say. Buy some more mugwort to take back later and fumigate the house using the same method. Also, boil a pot of hot water for bathing. Do you all understand? By the way, do you know where you can buy quicklime and coal?"

A follower quickly replied, "Handsome, lime can be bought over at the dock. As for coal... what is that?"

Jin Shuai patiently explained, "Coal is a black, stone-like fuel that can be ignited and burned."

Another attendant seemed to suddenly realize something and interjected, "Handsome, are you talking about coal? There's definitely a lot of it at the dock."

Jin Shuai nodded in satisfaction and then said, "Very good. Then you can go and inquire about the price later and buy some samples to take back to your residence."

At this moment, the young girl who had been quietly busy nearby came over and said softly, "My lord, I have already put the vinegar in the young lady's room."

"Quickly open the windows to let in some fresh air, then help your young lady cover herself well with the blankets. Next, boil some warm water, the temperature should be lukewarm. Find a towel, the kind you normally use to wipe your face, soak it in water, wring it out, and wipe your young lady's soles, groin, armpits, and palms in that order. After each wipe, you need to soak it again and wring it out, repeating this process three times. Finally, soak it again, wring it out, and place it on her forehead. Once the warm water is boiled, take out the vinegar, close the windows, and then start wiping. Do you all understand?" Jin Shuai explained, demonstrating the corresponding actions as he spoke.
