The next day after returning to the White Stone Building, Wu Lai, who had a good night's sleep, showed up in front of the suspension bridge of the three major workshops early. After returning to Seneca City yesterday, he sent Sting, Tielun, Wu Si and nine other slave coppersmiths here, because there are not only enough houses to accommodate these "technicians", but also other people including old Neptune. With their friendliness, these twelve slaves can integrate and get used to this place in the fastest time.

The drawbridge was slowly lowered, and Wu Lai walked into the paper mill with a smile on his face.

Not long after, in an unused warehouse of the paper mill, Wu Lai sat on a big chair with a smile on his face. Beside him stood Hei Wa, who was fully armed and holding a whip. The twelve "newcomers" stood obediently in three rows according to Wu Lai's assignment.

"Today, I formally welcome you into my family, and I, the citizen of Assyria, your new master, Seneca Woolelindo, solemnly promise that you have the right to use your loyalty and dedication to buy your freedom."

After finishing his opening remarks, Wu Lai changed the subject and his expression became serious. "Before today, you were all the best in the coppersmith industry in Yisai City. Some of you have created achievements in Yisai City that are worth celebrating for a long time, but all of these are in the past. In fact, they are not worth mentioning, because your so-called superb skills and wonderful ingenuity are nothing but a pile of garbage in my eyes."

The twelve newcomers frowned at the same time, with Esdin and the other three frowning even more so.

Wu Lai stood up, scanned everyone's expressions, and suddenly laughed, asking, "Are you unconvinced?"

No one said anything. According to the survival rules of slaves, disobeying the master is a taboo.

"You must be unconvinced, but you dare not say it out loud. Very good, I like you who are obedient." Wu Lai said with a smile, "Now, please listen to my question carefully."

"First question, do you know what bronze is?"

"Second question, do you know how to double the melting speed of ore at the same furnace temperature?"

"The third question is, do you know what are the drawbacks of the current common casting technologies such as smelting copper ore, making molds and pouring?"

Sting, Tielun and Wu Si were stunned, and the nine people behind them were also stunned.

After hesitating for a while and seeing that Wu Lai stopped asking questions and talking, Tie Lun raised his hand hesitantly: "Master, I want to ask a question."

"Ask," said Woolley.

"I have never heard of what the master just said. May I ask, is that a divine power? I mean melting ore." Tielun asked.

Divine magic? What a great imagination. After Wu Lai finished his complaints, he smiled and shook his head: "Although it's not, it's almost the same, because everything I just said came from the revelation given to me by the god Amon, and it was only given to me!"

Wu Lai's serious expression immediately made the twelve newcomers and Heiwa feel greater awe for him, and his next words, which were full of temptation, also made the twelve slave craftsmen present feel overwhelmed and unable to extricate themselves.

"Don't think that my meeting with you is accidental. I swear, it was God Amon who asked me to lead you out of the darkness, and then, together, change the world." Wu Lai said.

The master is still a teenager, but he already has the ambition to change the world?! Hei Wa was stunned. For Wu Lai, changing the world was not a difficult task, because in a broad sense, creating something or technology that has never been seen before can also be called changing the world.

But whether in a broad or narrow sense, Woolley's subsequent actions are slowly pushing the times forward.

After squeezing out the paper mill and the printing workshop, Wu Lai's dream of an arsenal test site finally got an independent space. It was between the printing workshop and the paper mill. If he hadn't been worried about a fire igniting the two workshops, Wu Lai wouldn't have minded making it a little bigger.

Smelting furnaces and casting furnaces were quickly built in the armory test site with independent walls and gates. Copper anvils, copper hammers, copper tongs and other coppersmith tools were also gathered in the shortest possible time. After various ores needed were transported to the test site in small batches, Wu Lai began to give lectures to the three skilled craftsmen and their assistants. These courses were unprecedented -

"Before we learn about bronze, let's first understand what alloy is..."

"…So, bronze is actually a type of alloy. When tin, aluminum, lead, manganese and other metals are added to brass and copper, it will have better rigidity, toughness, and wear resistance than a single metal…"

"The key to smelting ore lies in the furnace temperature, which is determined by the materials used to build the furnace, the shape of the furnace, and the fuel..."

"...When a certain metal begins to melt in the furnace, it means that the furnace temperature has reached the requirement to melt the metal. This sounds like nonsense, but this phenomenon can explain a new term, melting point. Every metal has a melting point. Under the same conditions, the melting points of different metals will never be the same..."

"...Usually, we use mold making and pouring techniques when casting, but their advantages and disadvantages are equally obvious, such as..."

The course ended after forty days, and Wu Lai immediately announced that the armory test site would enter a three-month internship period, which also meant that Wu Lai could finally give himself a few days off.

Woolley himself felt that it was time to take a break. Although he had the help of Gauguin and Neptune, after doing so much work by himself, it brought more than just physical fatigue.

After lying idly in the White Stone Building for a day, Wu Lai went to Greendo Manor the next day. After all, it was the only place in the world where he could recall his family affection.

Eaton, who turned one year old a month ago, is already able to call him brother in a baby voice. Wu Lai is happy about this but also feels a little emotional. He thinks that if his alcoholic father were still alive, he would definitely smile at Eaton's call.

"Eaton likes to suck fingers. Be careful not to let his saliva stain your clothes." Tina whispered to Wu Lai who was holding Eaton in his arms and teasing him.

"It's okay." Wu Lai smiled and glanced at Tina.

"You haven't been back for some time." Tina said again.

Wu Lai nodded. After that night, he always felt a little awkward when he saw Tina.

Madam Leah smiled and said, "Wu Lai, I heard that you bought some coppersmiths from Isaac City. Are you planning to open a copper workshop in Seneca City?"

"Not necessarily yet." Wu Lai did not directly answer Mrs. Leah's question.

Mrs. Leah was a little disappointed with Woolley's answer, but she quickly adjusted her mentality. While tidying her sideburns, she took the maid to the kitchen to see how lunch was prepared - Woolley promised her to have lunch at Greendo Manor, which was a big deal.

After watching Mrs. Leah's back as she left, Wu Lai lifted up the laughing Eaton from his arms. His original intention was to play a toss-and-catch game with his chubby brother, but he completely misjudged Eaton's reaction - the little guy kicked his legs quickly, and his little feet rudely kicked Wu Lai's nose.

Wu Lai burst into tears immediately, but it had nothing to do with being moved. It was just because he was really sore from being kicked.

"Are you okay?" Tina came over quickly.

"It's okay." Wu Lai answered vaguely while holding Eaton with one hand and covering his nose with the other.

"Let me see it quickly." Tina pulled away Wu Lai's hand that was covering his nose, looked at him with a distressed look, and hurriedly took out a handkerchief to wipe the tears from his eyes. "Eden is so naughty, does it still hurt?"

The latest novel is published first on Liu9shuba!

Wu Lai shook his head, and after staring at Tina for a while, he suddenly but seemingly naturally kissed Tina's seductive lips.

"Hmm..." Tina only had time to make this barely audible cry that was somewhat filled with anticipation and pleasure, and then she felt the tingling, warmth and exploration on her lips.

Tina's immature and clumsy reaction made Wu Lai very satisfied and proud, but he soon felt something strange. When he subconsciously "evacuated" and glanced towards the door, what caught his eye was Mrs. Leah who was covering her mouth with a look of surprise.

Wu Lai quickly stepped back a little, and then he saw Eaton's round eyes staring at him curiously.

After sitting up straight, Tina's cheeks flushed and she rubbed her handkerchief nervously.

"Woole, Tina, you two actually kissed..." There was suddenly a hint of excitement in Mrs. Leah's voice.

"Oh, don't get me wrong, Eaton kicked Tina's chin just now, so she begged me to check if it was red. Fortunately, it's okay." After calculating the viewing angle of Mrs. Leah's position, Wu Lai said calmly.

"Ah?" Mrs. Leah expressed her surprise and disappointment appropriately.

"Yes, mother, it's just as Woolley said, that's all." Tina said with her back to Mrs. Leah, blushing.

"Oh, well, I forgot to ask Woolley just now, do you like fried fish or fish soup?" asked Mrs. Leah.

"Fry it into slices, at least that way it won't taste too fishy." Wu Lai replied calmly.

"Okay then." Lady Leah turned and left.

Tina was stunned, bit her lip and twisted Wu Lai's leg.

"Wulai, you are a rogue." Tina said in a low voice.

"Hehehe..." Eaton suddenly laughed.

Wu Lai's vacation was over after just two days of rest, because the comprehension ability and practical operation level of Junstin and others exceeded his imagination. In other words, it took only four days for the armory test site to achieve the effect that Wu Lai originally thought would take three months to achieve.

"Wealth and status force people to come here." Wu Lai exclaimed in admiration as he flipped through the samples sent by the armory with great interest.

Gauguin, who was accompanying him, was extremely curious. Seeing that Wu Lai was in a good mood, he boldly asked, "Master Wu Lai, what are these?"

"This is..." Wu Lai almost blurted out an answer, but then he realized it and glared at Gauguin. He said with some dissatisfaction, "Gauguin, haven't I already told you that no one can ask about it?"

"Okay, Master Wu Lai, I understand." Gauguin said quickly.

"That's better." Wu Lai curled his lips and returned his gaze to the object in his hand.

After looking at it for a long time, Wu Lai reluctantly put it down and closed the lid of the wooden box. After a moment of hesitation, he called Gauguin, who had retreated to the side, and said, "Gauguin, quietly call the Pompeii priest over here, and don't let anyone else notice."

Gao Geng nodded respectfully, but was wondering in his heart, what does Master Wu Lai want to do?
