Xia Pingan opened his eyes and found himself in a workshop. Looking around, he saw a large amount of malachite and charcoal piled in the yard of the workshop.

The heat wave is rolling in the underground kiln not far away. A group of technicians are busy putting malachite on the burning charcoal to smelt it. The smelted copper water is flowing into the mold that has been cured long ago along the guide channel on the ground.

, those molds are all bronze mirrors.

Seeing the malachite and charcoal, Xia Pingan's mind settled down. This was the fire method for smelting copper, a metallurgical method that appeared in the Shang Dynasty of China.

When he saw the two characters "Yang Sui" before, he was not completely sure what the world bead was used for, because there was a surname of Yang in ancient China. Who knew if this world bead was the name of a certain person, but when he saw it

After arriving at the workshop here, Xia Ping'an felt reassured.

Xia Ping'an looked at the clothes he was wearing, and then at the clothes worn by several people around him, and he probably made a judgment in his mind. The era he was living in at the moment should be the Western Zhou Dynasty. There is "Zhou Li·Qiu Guan Si Kou" in "

It is recorded that the Si Xuan family held a fusui in their hand and took the bright fire from the sun.

At this moment, he and several people who looked like craftsmen were lowering their heads and listening to a person who looked like an official lecturing.

"... In a few days, it will be Dazai-sama's birthday. All the princes and the internal affairs department have expressed their opinions. Lord Sikong ordered our work office to cast exquisite utensils and present them. Dazai-sama likes exquisite tools the most. You are all members of the work office.

Master craftsmen, this time the errand will fall on you. If it is done well, Lord Sikong and I will both be generously rewarded. If it is not done well!" The face of the lecturing official darkened, "Don't blame me then.

No mercy..."

There was no prime minister in the Western Zhou Dynasty. The position of Dazai was equivalent to the prime minister in later generations. Sikong was also called Si Gong in the Western Zhou Dynasty. Sikong was responsible for managing hundreds of workers and building civil engineering, water conservancy and other projects. This work office should be a "state-owned factory" affiliated to the Western Zhou Dynasty.

, the official-looking person lecturing in front of me should be one of the "staff members" who manage this place.

At that time, the division of official positions was not as detailed as that of later generations. The so-called "staff members" were assistants, subordinates, and followers who worked with the big shots. For example, Sikong's "staff members" would be assigned to manage the work of smelting copper.

Department.

"We can cast some bronze mirrors as tributes..." a craftsman said.

"Bronze mirror?" The staff member looked a little unhappy, "Is there still a shortage of bronze mirrors in Dazai-sama's house? I don't know how many people from various princes and civil servants will give this thing. Dazai-sama always rewards me and others with bronze mirrors.

It’s for the staff, are you asking Lord Sikong to send the same thing as others?”

Bronze mirrors didn't work, so the other craftsmen spoke one by one, some talking about wine vessels, tableware, bronze lamps, copper stoves, copper pots, copper sheep...

These suggestions were all rejected by the subordinate officer with his head shaking, saying that they were too ordinary and that giving these things did not show Lord Sikong's ability to manage hundreds of workers.

Xia Ping'an sighed secretly, as expected, gift-giving has been a major subject from ancient times to the present.

"Can't you come up with something ingenious? It'd be best if it's something Dazai-sama has never seen before. It's unique. If any of you can come up with it, I'll reward you with a hundred catties of gold and ten slaves..." The subordinate's eyes were waiting for Xia Ping'an.

Scanning people's faces one by one, all the craftsmen were silent and looked embarrassed, "There are still a few months, you can think about it slowly!"

Seeing that the subordinate officer was about to leave with a disappointed look on his face, Xia Pingan said, "I thought of something unique, maybe I can dedicate it to Lord Dazai!"

The subordinate officer suddenly became interested and said, "Oh, what did you think of?"

"I thought of that thing that can make fire against the sun on a sunny day!" Xia Pingan said calmly.

"Mu Sui?" The subordinate official's face turned gloomy, and he said with anger, "You don't want to live anymore, yet you dare to make jokes and deceive me at this time..."

"Wooden firewood is the one that drills wood to make fire. What I am talking about is not wood firewood, but gold firewood. It does not require wood, but is made of gold and copper. It is like a bronze mirror, but it is different from ordinary bronze mirrors.

After the golden sui is pointed at the sun, it can focus the sun on one point and ignite the moxa to make fire..."

The subordinate official was not completely pig-brained. He knew that light was hot and that bronze mirrors could reflect light. Hearing Xia Pingan's eloquent words, he could focus the light in the bronze mirror to a single point. He suddenly became energetic.

The whole person suddenly became excited, "You can really create this thing. If you can really create it, it will be a great achievement!"

"I have never made this thing before, but after thinking about it these days, I think this method should be feasible!"

"How did you get the idea?"

"Last time I saw a bronze mirror placed in the warehouse and was dented by heavy objects. When I used the dented bronze mirror to calibrate the light, I found that the light it reflected was no longer as straight as before. I thought

Perhaps we can use this method to make a special bronze mirror for making fire..."

The subordinate official thought for a while, and it seemed that it was indeed the case. The bronze mirrors they produced here had to be carefully polished, so that the surface of the mirror could not be uneven. Once there were dents and bulges, it would not be possible to shine on people. Just shine it against the light.

Light also distorts, "How long does it take you to make it?"

"Give me a few manpower and we can build it in a few days!" Xia Pingan said directly.

"Okay!" The subordinate official high-fived excitedly, "I will give you one month. Within this month, you can dispatch all the craftsmen and slaves in this department!"

"yes!"

It would be easy if there were craftsmen at his disposal. Xia Pingan asked several craftsmen to make several different new molds. The new molds were like the bottom of a pot, with curvature. When the molds were ready, they would directly use the process of making bronze mirrors.

, pour copper liquid into the mold, and several strange-looking concave "bronze mirrors" are produced.

The manufactured bronze mirror also undergoes polishing and polishing processes, etc. It only takes a few days and is completed quickly.

After the Yang Sui was completely polished, in the afternoon of the next day, the subordinate official also came. All the craftsmen and slaves of the Work Office gathered in the open space outside the Work Office. Everyone was shocked and curious to see the strange appearance.

How does the bronze mirror draw fire from the void?

Xia Pingan held the bronze mirror, faced the sun, looked for the focal point of reflection, and then placed a ball of moxa velvet on the focal point of reflection.

In front of everyone, in less than a minute, the ball of moxa started to smoke and then burned.

"The divine thing...the divine thing...it is indeed a divine thing..." Seeing this magical scene, everyone screamed, and the staff officer almost jumped with joy.

No one has ever been able to make fire from light before, but this strange-looking bronze mirror made by Xia Pingan can actually make fire from light. This is much simpler than drilling wood to make fire. It is not an exaggeration to call it a divine object.

point.

The process of making Yangsui was smooth and smooth, without any twists and turns.

How this Yang Sui was finally given to Master Sikong, and how it was finally presented to Master Dazai, Xia Pingan doesn't know.

The world formed by the Boundary Pearl was shattered again.

This time fifteen points of divine power were added, and Xia Pingan's body's upper limit of divine power exceeded 420 points and became 425 points.

The body changes even more!

Xia Ping felt that his body was being continuously washed by the powerful energy pouring in from the void. Faintly, his body seemed to be no longer completely closed, but had opened a portal, creating a connection with the void of the universe outside his body.

made some connections.

This feeling is amazing.

In the caisson of the secret mandala temple, there are 15 more points of divine power, and in the temple, there is an additional relief sculpture. The relief sculpture is exactly the scene of Xia Ping'an's invention of Yang Sui making fire against the sun. A beam of light shoots from the sun to the sun.

The light on the flint was golden, as if it were real.

The characters "Yang" and "Ju" on the mountain of golden characters were lit up and stood out from the mountain.

In the room, Xia Pingan opened his eyes and looked at the time. He found that just over an hour had passed. He stood up and moved his hands and feet. He felt that his body at the moment had entered a whole new realm. It was even better than before.

It was more than twice as strong. When he breathed, the cells in his body seemed to be able to freely absorb a trace of external energy.

Xia Pingan punched out, and the air in the room exploded, like a popcorn machine exploding a cannon.

A figure flashed outside the house, and Man Zijin had already rushed outside.

"I'm fine..." Xia Pingan said.

After hearing Xia Pingan's words, Man Zijin retreated again.

Xia Pingan used his remote viewing ability to look outside.

Damn, more than an hour has passed. Those demon rats and big spiders are still more than 20 kilometers away from the base of Yunwan Mountain. Those monsters are walking slowly on the road. It seems that they have no specific target and are just following the path.

I came in along the highway to investigate.

As for the base, they have already set up a strong formation five kilometers away from the entrance, and the two sides have not exchanged fire yet.

Xia Pingan curled his lips. He still had plenty of time and he was not in a hurry.

Xia Pingan took out the second boundary bead he got. There were only four divine words on that boundary bead - Boyi Zuojing.

With blood dripping on it, Xia Pingan's body was quickly wrapped in a ball of light again.

The last boundary pearl was the invention of Yangsui. This boundary pearl is about digging a well. The legendary Boyi was the first person among the Chinese ancestors to use underground water. He was the first to dig into the ground to draw water and dug a well.

This world bead is quite simple for Xia Ping'an, it's a complete question.

But Boyi's other achievement will be more eye-catching. After Boyi assisted Dayu in flood control, he wrote "The Classic of Mountains and Seas". In addition to being the first person to build wells, Boyi may also be the first person to complete a round-the-world journey in ancient China.

Man, the ancient book "The Classic of Mountains and Seas" is actually Boyi's notes on his global travels...

…

This second world bead fused faster. In less than ten minutes, Xia Pingan opened his eyes again. The divine power in the caisson of his temple increased by 10 points, and the upper limit became 435 points.
Chapter completed!
