Puyang has been widely expanded in recent years. The villa is only more than ten miles west of the old city. If it is not controlled, the small hills where the Taihe Villa is located may have been annexed by Puyang New City. But after all, the status of Taihe Villa is transcendent, so Puyang deliberately or unintentionally ignored the direction of the villa during the expansion process.

With the Ether and Villa as the center, a forest is planted in a radius of dozens of miles. The villa is surrounded by this sparse forest and is as quiet as ever.

When the ancient blue disc-shaped speed car passed through the Five Elements and Four Symbols and landed in front of the courtyard, this ancient and quiet villa finally became boiling.

"It's really the boss!"

Guan Hai shouted, looking extremely excited: "The boss is back, the boss is back!"

The fierce sound rippled, and many people came from the scene. After a few breaths, fifty or sixty people gathered in front of Zhao Yu.

This is not over yet. Then, the little kid, seven or eight years old, five or six years old, and even three or four years old, suddenly came out, hiding behind the adults, looking at them secretly with curious eyes.

Zhao Yu laughed.

The hard work that had been done at the beginning was finally in vain. These little kids must be descendants of Guan Hai and the others who protected the hospital.

Men and women, looking at Zhao Yu, bowed together: "Greetings to the boss, madam!"

Zhao Yu nodded: "No need to be polite. I haven't seen you for ten years. It seems that you are all pretty good. I feel very comforted. The villa finally has the atmosphere that should be..." His eyes swept over the children hiding behind the adults, and he was very satisfied: "The villa needs inheritance after all..."

"Okay." After a pause, Zhao Yu waved his hand: "Cai Bo and Guan Hai stayed, let the rest of them be separated."

"Here."

After a few words, without saying much, everyone was sent back, leaving only Cai Bo and Guan Hai.

Just as she was about to speak, she saw that the mature and mature girl Cai supported Mrs. Cai, surrounded by four maids including Xiaochun, and walked out of the yard.

After ten years of seeing each other, I think Cai Xiaomei is still twenty-five or six years old. The young and lively devil king at the time has long been destroyed in time. Now, when I look at it, she is as mature as Zhao Ji, with a mature temperament and gentle as jade. In comparison, Mrs. Cai looks a few years younger. As for the four maids such as Xiaochun, they are like Cai Xiaomei, and are also very young.

Zhao Ji was very excited and hurriedly stepped forward to worship her mother, hugged Cai Xiaomei, her eyes flushed.

Zhao Yu met the old lady first. When the other four concubines greeted the old lady, he called Guan Hai and Cai Bo aside and asked about the affairs of the other courtyard over the past ten years.

"After the master and his wife left, the old slaves were in charge of the chores of the villa." Cai Bo said: "When the master left, Zuo Ci Zhenren and Hua Tuo stayed in the villa for more than a year, and they all went there. Every year on the Lantern Festival, Cao Gong would come to the villa with eleven of his disciples. Within three years, they also had families."

After briefly talking about the changes, Cai Bo said in detail: "Three years, Cao Gong unified the world. Four years, Cao Gong started to build a large-scale talisman carriage and ship. The furnace and cauldron that the master opened when he left was finally used in practice. Cao Gong did not directly intervene in the core power module of the talisman carriage and ship. He just sent a large number of materials every half month or a month, and the old slave was in charge of the refining process."

Zhao Yu nodded slightly: "In other words, it has been six years since the construction of talisman vehicles and ships on a large scale? What are the results?"

Cai Bo said: "In four years, no real results were achieved, and even an accident occurred. The first batch of ten talisman flying boats built fell during the test flight because of the flaws engraved in the Taoist pattern, which affected dozens of lives."

"Oh?" Zhao Yu's expression turned, and then nodded: "Yes, the talisman car and ship are not toys, they are not that easy to make."

Cai Bo said: "What the master said is. Therefore, after that, Cao Gong's second test flight was at the end of five years after more than a year. I heard that due to the accident, Mr. Mo personally led the team to study and worked with Taoist Master Zuo Ci and others to solve the problem within more than a year. The second test flight was made."

"It will be done twice, it's great." Zhao Yu was quite satisfied and said, "How many core power modules have been refined so far?"

"The old slave has records." Cai Bo said: "Since the end of the fifth year, the demand for core power modules has been getting bigger and bigger every year. Including the batches that Cao Gong sent people to transport them half a month ago, the total number has exceeded 5,000."

"Five thousand?!"

Zhao Yu laughed: "Not bad, not bad!"

In other words, so far, Cao Mengde owns at most 5,000 talisman speed vehicles.

This number seems not big, but if you think about it carefully, you will know how amazing the aspects involved are in this era. Just talking about the fine steel and jade consumed by 5,000 power modules is an astronomical number.

Thinking of this, Zhao Yu couldn't help asking: "Are all the gold and jade materials required for the core power module refined by the furnace and cauldron in the other courtyard? Meng De did not organize anyone to study it himself and use ordinary means to alloy smelter?"

Cai Bo smiled and said, "My master, two years before the large-scale construction of talisman carriages and ships, all the gold and jade materials were indeed made of furnaces and cauldrons in the other courtyards. In the seventh year, the capable people under Cao Gong learned about the methods of ordinary smelting. Since then, the materials transported are all ordinary gold and jade, not stainless steel and jade."

Zhao Yu was satisfied and smiled and said, "It's great."

What Zhao Yu was satisfied with was not only because of the higher quality, but the consumption was greater. It was also because after the smelting technology of all materials was thoroughly understood, it was a huge change for the entire society. The material of gold and jade was tough, wear-resistant, corrosion-resistant, and not afraid of oxidation. More importantly, it was able to circulate the Yuan Qi of the Heaven and Earth. The benefits were immeasurable. Once the smelting technology of gold and jade was thoroughly formed and could be mass-produced on a large scale, the world would definitely change in every corner.

"So over the years, the scale of steel production under Meng De's rule has increased greatly, and the mining industry has become more and more prosperous." Zhao Yu said, and then said, "How is the villa itself in the past ten years?"

As he spoke, he had already arrived at the earthen courtyard.

The fire in the yard has been in full swing for ten years. When Zhao Yu left, he activated the furnace. If the furnace was not activated, he would not be there. Once Cao Mengde wanted to build a large-scale talisman carriage and ship, he would be stuck here.

Therefore, the formation gathered with the Yuan Qi of Heaven and Earth, which was burned in vain for four or five years.

Fortunately, after some transformation of the Five Elements and Four Symbols Formation, these consumptions are not very burdensome.

Cai Bo said: "Every time Cao Gong sent gold and jade, the old slave could make it into a finished product in up to three days. Therefore, there was no accumulation of materials."
