The foreign man smiled, shook his head, and said, "The Five Elements and Eight Trigrams are extremely profound. They have thousands of years of history in your country. I've only learned the basics. Now I need to prove my hypothesis bit by bit through experiments."

The woman took a deep breath and said dissatisfiedly, "Anyway, you, a foreigner, are using our people for experiments and then using them to prove the arguments of our ancestors. This is really a bit far-fetched."

The foreign man sneered after hearing this, then spread his hands and said, "Who made your country so weak? You paid a lot of money to ask me to do this experiment for you."

After saying this, he turned back to the machine and continued to observe its operation. The woman stood quietly by, watching the alchemy experiment in the machine thoughtfully.

She knew that this person was hired by the master to make elixirs for him. No matter how unwilling she was, she had to complete the master's orders unconditionally. This was the meaning of her life. When the master no longer needed her, it would mean that she...

He shook his head vigorously, looked at the foreign man and asked, "What should we do next?"

The foreign man tilted his head slightly, his gaze as passionate as if he wanted to strip the woman naked. He looked her over and replied, "The next steps will require more refinement. I need to continue adjusting the heat to ensure the medicinal properties of each herb and the ginseng blend perfectly. At the same time, I also need more data to verify my hypothesis."

The woman nodded, but her heart was filled with confusion. She didn't understand why this foreigner was so fascinated by her country's Five Elements and Eight Trigrams and alchemy, even to the point that her master had spent so much money to hire him to study them. But she knew that this was not her concern. Her only task was to ensure the smooth progress of the experiment.

Time passed slowly, and the flames inside the machine danced, as if telling ancient secrets. The foreign man observed every detail intently, his eyes filled with a desire for the unknown and a determination to succeed.

The woman silently recorded the data. Although she felt a lot of dissatisfaction in her heart, she also understood that this was her duty. She hoped that she could complete this task for her master, and at the same time, she also hoped to learn something useful from this foreigner.

As time passed, the experiment entered a critical phase. The foreign man began adjusting the machine's parameters, trying to find the optimal conditions for refining the elixir. The woman watched nervously, fearing any mishaps.

Finally, after countless attempts and failures, the experiment achieved a breakthrough. A rich medicinal aroma emanated from the machine, as if possessing magical powers. The foreign man cheered excitedly, knowing he had succeeded.

The woman looked at the excited expression of the foreign man and couldn't help feeling an inexplicable sadness in her heart.

Since she arrived, she has conducted more than ten experiments, each time taking five lives. She was unable to share this joy. She thought of those who lost their lives, who became victims of the experiments.

"We succeeded..." The foreign man turned his head, a smug smile on his face. The woman bit her lip and whispered, "Those people..."

The foreign man was stunned for a moment, then laughed, "Their sacrifice is worth it, this will be a great breakthrough!" A hint of madness flashed in his eyes.
