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

Five days later, around ten o'clock in the morning, sunlight streamed onto a dock outside Tokyo. Jin Shuai and a group of servants slowly disembarked from their ship. Their gazes fell upon the muddy, uneven road, and Jin Shuai couldn't help but frown slightly. The scene before him made him deeply aware that this place truly possessed an ancient and rustic atmosphere; it was indeed very old-fashioned.

Before long, a servant successfully summoned several simple oxcarts. Jin Shuai reluctantly boarded one of them, and as the wheels slowly turned, the cart began to sway. The oxcart bumped along for about an hour before finally arriving at the Jin family mansion in the inner city.

As Jin Shuai stepped down from the oxcart, the first thing that caught his eye was a brightly colored, eye-catching red-lacquered gate, its style quite similar to the gates of wealthy families in television dramas. Above it hung a plaque with the two large characters "Jin Mansion" prominently displayed. Just then, Butler Jin hurriedly approached Jin Shuai and said, "Handsome young man... this is our new home in Tokyo. The old master hasn't returned from his official duties yet."

Afterwards, Jin Shuai followed the butler and strolled around the mansion. The residence covered approximately 2000 square meters (about 3 acres), with most of the area consisting of individual rooms. Only a small pond was located in the center, which could be used for raising fish and also served a fire-prevention function. However, unlike the magnificent pavilions and fragrant gardens depicted in the TV series, it lacked any of the grandeur of the place, which was rather disappointing.

Jin Shuai smiled and said to Liu, "I'd like to take a bath to wash away my fatigue." He then turned and headed towards the bathroom. After his bath, he ate some food to fill his stomach. Then, he summoned his steward, Jin, and instructed, "Take me to find some skilled blacksmiths."

Jin Shuai had already devised a plan in his mind—to make several practical pulleys. Today at the docks, he had witnessed firsthand the workers laboriously loading and unloading cargo from ships, relying entirely on manpower and rudimentary wooden tools—a slow, laborious, and time-consuming task. Thus, an idea sprouted in his mind: wouldn't it greatly improve work efficiency if some convenient devices could be created?

Besides looking for a blacksmith, Jin Shuai also planned to inquire about any kilns in the vicinity that fired pottery or porcelain. After all, some parts might require ceramic products to function properly. Furthermore, he decided to visit a blacksmith's shop to see if he could find a suitable craftsman to help him create the items he needed. Perhaps there would be highly skilled and experienced individuals there who could satisfy his pursuit and imagination of these novelties!

After leaving home, Jin Shuai, along with his butler and several attendants, headed towards the bustling East Market. They weaved through the crowds, their eyes searching for their target. Finally, they spotted a blacksmith shop on a street corner.

Entering the shop, Jin Shuai carefully took out his meticulously drawn pulley design blueprints from his pocket and handed them to the experienced blacksmith. The blacksmith took the blueprints, examined them carefully, a hint of appreciation flashing in his eyes, and nodded, saying, "This thing looks quite novel, but with my skills, I should be able to make it. However, the price… each one will cost two hundred copper coins." Hearing this price, Jin Shuai thought for a moment but didn't hesitate much, because he knew the value of such a unique design.
