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

Finally, Jin Shuai looked at Liu Ma and said, "Liu Ma, you should go and continue to focus on making the underwear. Butler, you come with me to the Craftsman's Courtyard. You two go and get busy!" After saying that, he stood up and left the restaurant with the butler.

Upon arriving at the blacksmith's courtyard, the foreman ran over excitedly, his face beaming with joy. He carefully pulled a slightly bluish piece of glass from his pocket; its translucency was already quite good. Jin Shuai nodded in satisfaction and smiled, saying, "Although it's a bit thick, that's not important; we can improve it gradually. I'll teach you how to thin it later. Please remember the proportions carefully; once the porcelain master from our hometown arrives, he'll be able to craft it into exquisite glass artifacts."

Jin Shuai then explained in detail to the blacksmith how to make rectangular fryers, and asked him to make ten at a time. Afterwards, the scorched iron ore needed to be ground into powder and sieved before being delivered to the carpenter's courtyard next door. The blacksmith, smiling, readily accepted the task and quickly began working.

Jin Shuai and his steward went to the carpenter's courtyard. As soon as the carpenter saw Jin Shuai, he immediately greeted him warmly. Jin Shuai smiled and asked, "Please ask the bricklayers to come and see me." Before long, three dark-skinned, honest and simple bricklayers came to Jin Shuai and bowed respectfully, saying, "We pay our respects to Your Excellency."

Jin Shuai quickly waved for them to stand up and said with a friendly smile, "No need to be so polite. May I ask where you all come from? Which one of you has the best skills? Since you possess such skills, why choose to sell yourselves?"

"Your Excellency, we all live in the outer city. Our families have contracted chickenpox and we need money for medicine, so we have no choice. My skills are the best among the three of us," a dark-skinned man said humbly.

"From now on, you'll be the boss. You must keep the things I tell you strictly confidential. After I finish teaching you, the butler will give you medicine for treating chickenpox. Send someone to deliver it back to you." Jin Shuai said firmly, looking at the man in front of him.

Upon hearing this, a look of surprise and gratitude flashed in the man's eyes. He hurriedly knelt down and kowtowed, saying, "Thank you, Your Excellency, for saving my life. There's almost no medicine left in the city, and the medicine that is available is ridiculously expensive!"

Jin Shuai waved his hand, signaling the men to get up, and then began to explain the skill they were about to learn: "Alright, get started! What I'm going to teach you is called concrete. You need to prepare quicklime powder, clay powder, iron ore powder, and fine sand, and mix them together with water in the right proportion. This is called fine aggregate concrete."

After explaining these points, Jin Shuai began to explain in detail the function and dosage of each material, and demonstrated how to properly mix and use this new material. He hoped that through this training, these craftsmen would master the techniques for producing high-quality concrete, thereby improving the quality of construction.

As Jin Shuai explained, the three craftsmen gradually understood this new thing, and they were amazed. They began to look forward to the future.

Jin Shuai had been focused on teaching until Liu Ma called out, "Sir, lunch is ready!" Only then did he stop what he was doing. He said to the people around him, "Alright, call me again tomorrow afternoon after the concrete has set. Also, this afternoon we need to make five reinforced concrete slabs and five bamboo-reinforced concrete slabs of each type. Now you can go eat."

After lunch, Jin Shuai rested for a while and took a nap. When he woke up, he instructed Liu Ma to move all the ingredients for making fried chicken to the courtyard.
