Empress: Your Majesty, please respect yourself, I don't want to be promoted

Fu Hua's graceful figure gradually became only a rough outline in the increasingly dense water vapor.

"Aha…"

Fu Hua suddenly took a deep breath, and then gathered a large amount of spiritual power in his mouth.

In the next moment, with more than ten seals completed instantly, the spiritual technique was ready in an instant.

"Blow the storm!"

The spiritual energy in his mouth was violently spat out, and the surrounding wind spiritual energy began to gather rapidly under the influence of spiritual magic. A strange updraft soon formed, blowing the water vapor accumulated inside to high altitudes, and finally dissipated quickly.

The water vapor dissipated, and the scene inside appeared in front of everyone again.

But he saw that the mud and stone in the mold had begun to look like stone slabs.

Just like the first time he verified the mud and rocks brought by Liyue.

It can be seen that the mud and stone are slightly different from the cement in Lu Chen's impression, and the solidification process is different, but this is understandable, after all, the composition is not exactly the same.

However, the functions and characteristics of the two are similar, so there is no problem in treating it as cement.

After a while, a drop of sweat appeared on Fu Hua's temple.

"All right."

At this moment, Lu Chen suddenly spoke.

"Liangyu, you can stop."

As soon as he finished speaking, the spirit form next to Fu Hua disappeared almost instantly, but her expression remained as usual, not affected by the backlash of the interruption of the magic circle at all. It was obvious that she had reached the state of being able to retract and release freely.

Gu Simiao couldn't help but marvel at such a superb level of formation.

"The advantage and disadvantage can actually eliminate the backlash of the magic circle so easily. He is worthy of being the number one master under His Royal Highness the Holy King."

click...

Fu Hua tiptoed, her body floated up, and finally landed firmly behind Lu Chen.

"Thank you for your hard work, Liangyu."

Lu Chen said softly.

Fu Hua shook her head, and then smiled back.

Although nothing was said, everything was said without saying anything.

Seeing the tacit understanding between the two of them when they looked at each other, the empress frowned inexplicably, and then took a deep look at Fu Hua. In that look, she seemed to realize something.

The little hands under the dragon robe were slightly clenched.

"Lu Qing."

She took the initiative to speak, breaking the peace.

"Has the mud and rock solidified?"

Lu Chen looked away from Fu Hua and then nodded.

"Yes, Your Majesty, we can now start the follow-up tests."

"Then let's start right away."

The Empress ordered.

"Yes, Your Majesty."

Lu Chen bowed in agreement.

Soon, a group of officials from the Tiangong Department rushed forward, brought various tools and began to conduct various strength experiments.

Watching the craftsmen hammering on the mudstone with sledgehammers, Liyue's expression became tense again. Her small hand tightly grasped Lu Chen's big hand, and her big watery eyes were full of anxiety and expectation.

She doesn't know anything about the art of studying things. After all, she is just a martial artist, and she is also a top-notch master with first-class strength. She is also the best in the entire Xuanwu Army, otherwise she would not have been selected as the Xuanji Guard.

If she hadn't always gotten into trouble, her position in Xuanji Guard would never be lower than Tao Ji's.

And the reason why she tinkers with things that others think is messy is purely because she likes it.

Most of the things she tinkered with in the past had bad consequences and caused Fu Hua a lot of trouble. Naturally, none of them were of use. Mud and rocks were the first novelty she made that could be taken seriously. , and he is still valued by those he admires.

In her mind, Lu Chen, who studies heaven and is a real literary star descending to earth, said that this thing is very useful and can even change an era, which is of great significance.

She believed this, so at the moment when the results were about to come out, she was more nervous and excited than anyone else.

The empress was also a little nervous.

As the emperor, the highest authority in the empire, her understanding of the significance of the sudden appearance of mud and rocks was not much worse than Lu Chen's.

It can be said that mud and stone must be one of the most important modules in her prosperous world.

After a lot of trouble, several officials from the Tiangong Department soon trotted over with beams of joy.

"Your Majesty! Master Lu!"

After bowing and saluting, the two of them said with ecstatic expressions:

"After testing, the strength and other characteristics of this batch of mud and stone burned with pebbles as fuel and the mud and stone burned with the Sky Fire Array are almost exactly the same!"

"We made it!"

As soon as these words came out, the last stone in Lu Chen's heart finally fell to the ground.

A smile also broke out on the empress's face.

However, just when she was about to issue an order to reward all those who have contributed to the research and development of mud and stone, especially Liyue and Lu Chen, the two first contributors...

"too……"

Liyue on the side covered her mouth, tears shining in her big eyes.

"Great!"

She shouted loudly, and then she couldn't help but jumped up, hugged Lu Chen, and hung tightly on Lu Chen like an octopus, and said happily:

"Master Lu! Great!! I...I succeeded!!!"

Fortunately, although she was very excited, she did not lose her mind. She still firmly controlled the huge spiritual power in her body and did not harm Lu Chen.

Lu Chen just felt a little panicked.

It feels like being held by a primary school student.

"Ha ha..."

Lu Chen rarely laughed happily.

"I didn't expect that the new building materials project had just been established a few days ago, without even a clue, and now it has been completed. Not only has it saved countless expenses for the Ministry of Industry, but it has also saved a large amount of research and development funds. Liyue..."

He slowly stretched out his hand, gently placed it on the extremely excited Liyue's little head, and started rubbing it lovingly.

"You are truly the lucky star of our Tiangong Department."

"hey-hey..."

Liyue, who had calmed down a little, smiled silly.

She didn't refuse Lu Chen to touch her head. Instead, she pushed her head into his arms more vigorously, her little head getting closer to Lu Chen's palm, looking like she was enjoying it.

At this moment, she forgot that she was actually one year older than Lu Chen. Lu Chen did not treat her as a peer, but just like encouraging a primary school student, stroking Liyue's little head while constantly praising her.

In this seemingly harmonious scene, the expressions of the women behind Lu Chen were inexplicably strange.

Su Ning didn't think much about it. After her excitement faded a little, she couldn't help but sigh: "The study of studying things is really amazing. Who would have thought that these ordinary things can be mixed in a certain proportion and then processed in a certain way. The way and its characteristics can undergo such earth-shaking changes."

Hearing this, Lu Chen nodded in agreement.

"Yes, everything in the world is a miracle. Isn't this a manifestation of the Great Dao? And the meaning of the existence of Tiangongsi is to study the characteristics of all things and discover the laws among them. As long as you master the laws, you will have the opportunity to apply them Get up and benefit the common people, and once you reach this point, you will not be far from the true road."

As soon as these words came out, the spiritual veins that had just stabilized in the bodies of all the officials of the Tiangong Division became restless again.

"All right."

Lu Chen put down the blushing Liyue, turned his head, looked at the empress and Gu Simiao, and said with a smile: "Now that the cost of the mud and stone has been solved, it's time to move on to the next step."

"Without further delay, it is time to accelerate the mining and refining of coal in Heishan, Taihe County. Just in time, the Ministry of Household Affairs sent the first R&D fund of 10 taels of silver a few days ago, and it can be put to use now. .”

Chapter 237 Putting into production and building a factory

As long as it's something Lu Chen strongly recommends, the efficiency is surprisingly fast.

The next day when they went to court, the routine worship ceremony had just ended when Lu Chen came out of the crowd and raised his voice:

"Your Majesty, the research and development of a new building material has been completed. After discussion and verification by the Tiangong Department, it is officially named [cement]. It is in powder form before use and can be bagged, stored and transported. When used, sand and gravel are added and mixed in a certain proportion. , add water, stir, and then pour it into the mold. After it solidifies, it will be as hard as stone. If hard objects such as iron bars can be added to it to act as muscles and bones, its strength can be further improved..."

The report on the new building materials was naturally given to the courtiers. After all, the empress knew about it yesterday.

However, even so, the empress still listened very carefully, as if she was afraid of letting go of any details.

As Lu Chen told the story, all the courtiers showed shock.

New building materials...cement?

That's it?

So fast?Wasn’t it just a few days after the project was established?

And... add water, stir, pour into the mold, and shape it into any shape of stone without polishing?

Is there really such a magical thing in this world?

In shock, some of the courtiers who reacted quickly looked at Wu Yue, who was not far from Lu Chen.

Damn it, the Ministry of Household Affairs allocated funds to the Tiangong Department, and it only happened in the past two days. If the results are produced so quickly, isn’t it equivalent to the Ministry of Household spending 10 taels of silver to come up with new materials, this optical and auditory effect? Do you know that it must be an artifact that can significantly save project costs?

The Tiangong Division had come up with new building materials in just a few days. If Wu Yue, the Minister of Household Affairs, had hesitated for a moment during the previous court meeting, wouldn't he have to watch the empress earn this huge wealth? In the bag?

Now that the property rights belong to the Ministry of Housing and Urban-Rural Development, how much construction costs will be saved in the future?Or even produce more and sell them directly. Wouldn't this add an additional financial source to the court?

At this thought, they couldn't help but think about how rich her internal wealth would be if Wu Yue had given up investing in the research and development of new building materials a few days ago, and the patent for mud and stone had returned to the empress, and she had the two major financial resources of coal and mud. ?

Although the advent of new building materials, namely cement, will inevitably greatly reduce the imperial court's annual expenditure on the Ministry of Industry, the lack of a financial source is still very fatal to the Ministry of Household Affairs.

Facts have proved that Wu Yue's decision to go against all opinions and devote all his energy to the research and development of new building materials was right.

He caused Hu Bu to lose a lot of money due to coal mining, but by betting on mud and rocks, he gained Hu Bu an unimaginable amount of wealth.
