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

Just when the Yuzhou Guard was showing off its power in Nanyang Mansion, Lu Chen was staring expectantly at the light gray turbid solution in front of him.

Not only him, but all the officials of the Tiangong Department gathered together at this time, surrounding a large wooden barrel with Lu Chen, as if they were witnessing some sacred moment.

click...

Su Ning held a shovel and shoveled the coal pile next to the barrel without any image, and shoveled it into the barrel.

goooooooo~

The moment the coal fell into the barrel, the solution in the barrel suddenly seemed to be boiling, with dense bubbles constantly emerging.

After a while, the bubbles gradually disappeared.

When the bubbles completely disappeared, Lu Chen had someone fetch the iron mesh he had prepared in advance, and then he personally carried the wooden bucket and poured it into the iron mesh. He got a pile of coal that had been processed to become even blacker.

Then Lu Chen put the iron mesh containing the charcoal into a bucket of water and washed it several times before taking it out.

Immediately afterwards, Su Ning couldn't wait to come over and used a secret technique to quickly dry the charcoal.

It didn't take long for the surface of the coal to become extremely dry.

"So……"

Lu Chen suddenly took a deep breath and slowly took out a few Fierce Fire Excerpts.

"It's time to witness the miracle."

With that said, he was about to open the Fierce Fire Folder.

Everyone held their breath and gazed nervously at the fierce book in Lu Chen's hand.

After nearly a month of tireless efforts, whether the method of studying things can rejuvenate and strengthen the country, everything will be verified at this moment.

And at this moment-

"His Majesty is here!"

Outside the door, a high-pitched shout suddenly came.

Everyone suddenly looked stern, then quickly calmed down, put down what they were doing, and all looked towards the door.

Then there was a burst of rather rapid footsteps outside.

A few breaths later, the empress wearing a red dragon robe appeared in everyone's sight. A pair of bright eyes fell on Lu Chen for the first time. That world-famous face was unreservedly reflected on Lu Chen. Morning eyes bloom.

"Lu Qing, am I not late?"

Chapter 222

Lu Chen couldn't help but smile when he saw the empress coming.

"No, Your Majesty came at the right time."

Hearing this, the empress smiled knowingly.

"Really? That's fine."

After others reacted, they quickly bowed to the empress.

The empress waved her hand, and then walked to Lu Chen's side naturally in a gust of fragrant wind.

The others subconsciously moved away, keeping the distance between the emperor and the empress that should be maintained between monarchs and ministers.

Lu Chen wanted to stay away from the empress, but he couldn't stand the empress's habit of having no sense of boundaries, so he didn't bother to worry about it.

Anyway, the empress's favor towards him is already in heaven, and that's not bad at all.

"Is this charcoal that has been treated harmlessly?"

The empress pointed at the coal in front of her and asked softly.

"Ah."

Lu Chen nodded, and then asked Su Ning to explain to the empress. He didn't know if he thought it was troublesome, or if he wanted Su Ning, a rookie who already represented the way of studying things to some extent, to show more face.

Su Ning glanced at Lu Chen gratefully, then organized her words a little, and began to explain the harmless treatment technology of charcoal that they had developed during this period.

That is to say, using the principle that all things interact with each other, we first analyze why burning coal produces a harmful smoke, verify its ingredients, and then prepare a cleaning agent that can dissolve the harmful ingredients as much as possible, and finally screen the carbon and bake it. Dry and set aside.

And what they are doing now is the most critical step.

Verify whether the cleaned charcoal still produces harmful smoke.

If it succeeds, it will be a milestone achievement for those of them who are studying the way of investigating objects. If they fail...then they can only continue to study without sleep and food.

Although Lu Chen did not explain it himself, the empress listened attentively.

"I understand."

After Su Ning finished speaking the core content, the empress raised her hand and said to Lu Chen:

Now that everything is ready, let's light the coals now. "

"Yes, Your Majesty."

Lu Chen responded, and then opened the Fierce Fire Booklet very simply.

Whoa whoa whoa!

Violent flames spurted out from the mouth of the fold, and the scorching air waves even made a strong sound of spitting fire.

The next second, Lu Chen placed the charcoal under the barbed wire with a strong fire, and continued to heat the charcoal on it.

When the coal gradually turned red under the fierce fire, everyone held their breath involuntarily and stared at the coal in front of them.

It didn't take long for Fierce Fire Zhezi to exhaust its fire spirit power and be completely extinguished.

At the same time, the charcoal on the barbed wire continued to release bursts of hot breath to the surroundings, and the surrounding air began to visibly shake under the high temperature.

Seeing this scene, Su Ning and others' hearts were raised in their throats.

Even the empress raised her eyelids with anticipation in her eyes.

A few breaths passed.

The coal is still burning steadily, and the surrounding air is getting hotter and hotter.

Half an hour passed.

There was almost no change in the coal, and the surrounding temperature gradually stabilized.

The heat waves came one after another. The faces of several officials of the Tiangong Department, who were not very powerful, broke out with hot sweat. They subconsciously took off their thick coats, while the palace people behind the empress felt as if they were on a stove. People are so hot that the coldness brought by the cold wave that has gradually faded in recent days has also completely dissipated in this heat wave.

Their faces were full of disbelief. They seemed to have never imagined that a mere piece of coal, after being lit, could make the surroundings so hot and even make the whole room as warm as spring.

It simply broke their cognition.

A quarter of an hour passed, and the charcoal was finally consumed a little in a wisp of sparks.

And during the entire burning process, there was no smoke or pungent smell at all!

"Success...success!"

Su Ning was the first to react, and a look of ecstasy quickly appeared on her pretty face.

She jumped up with excitement on her face. While everyone was still struggling to recover from the huge impact, she suddenly hugged Lu Chen and shouted loudly: "Master Lu, we succeeded!"

At the same time, her eyes also turned red inexplicably, and the spiritual energy in her body began to stir wildly, constantly impacting her spiritual veins. The surrounding spiritual energy also began to pour into her body, and was quickly transformed into spiritual energy through unconscious refinement.

Lu Chen: "?"

Suddenly the soft jade smelled warm and fragrant, and he couldn't help but feel confused.

Then, before he could react, he suddenly felt a piercing gaze coming from beside him.

"Su Si Ye."

An inexplicable cold voice suddenly sounded, but it was the empress who spoke expressionlessly:

"Pay attention to your courtesy."

Su Ning was startled by her indifferent words and quickly let go of Lu Chen.

"Hug...I'm sorry, Your Majesty, I am so happy that I can't help myself."

The empress raised her eyes and glanced at her.

Lu Chen tidied up the wrinkles on his body a little, and seeing that the empress seemed to have serious intentions, he said casually: "Your Majesty, Miss Su and the others have been studying coal without sleep and food these days, and now they have finally achieved results. It is only natural for people to be excited for a while. , please don’t be harsh.”

Hearing this, Su Ning immediately looked at Lu Chen with gratitude.

Whether it is a serious or minor act of disobeying the emperor depends on what the emperor thinks.

If the empress doesn't care about her, then everything will be fine. But if the empress is unhappy, it will be a huge sin.

And Lu Chen, a famous figure in the Empress's dynasty, spoke for her. Considering the Empress' trust in Lu Chen, no matter how unhappy she was, she would give him face and make this matter less serious.

Sure enough, after Lu Chen finished speaking, the empress's chest rose and fell violently for no apparent reason, and the cold look on her face gradually disappeared.

"Lu Qing's words are reasonable, but Su Siye..."

She nodded slightly, then turned her head, looked at Su Ning, and said calmly: "This is the Tiangong Department, the yamen of the imperial court, and you are now an official of the imperial court. Please abide by your duties, bear in mind the court etiquette, and don't do anything else. If you do something out of the ordinary, I will not hold it against you because it is your first offender, but I cannot do anything inappropriate before you a second time. Do you...understand?"

Su Ning felt like she was being pardoned and nodded quickly.

"Wei Chen understands, thank you for your forgiveness!"

While responding, she couldn't help complaining in her heart. Mr. Lu clearly said that His Majesty is tolerant and generous and does not stick to trivial matters. She just couldn't help hugging Mr. Lu just now. It was not intentional, and she did not directly offend Long Yan. How could His Majesty? So serious?

It seems that His Majesty's generosity and informality are only for Mr. Lu, and others should do as they please.

After the incident, the empress carefully stared at the burning coal on the barbed wire fence. She didn't smell any strange smell in her nose, and her eyes suddenly showed curiosity.

"Lu Qing, does this specially treated charcoal really produce no harmful smoke when burned?"

Lu Chen smiled.

"Not sure yet, but since the pungent smell and thick smoke have disappeared, it should be almost done. Next, we just need to use some ordinary little beasts to verify it and measure other indicators."

Hearing this, the empress nodded clearly.

Indeed, this thing cannot be launched immediately until it is absolutely safe.

However, the charcoal has been burning for such a long time, and the people in the room did not feel any discomfort at all except feeling the heat. This is enough to prove that the technology of charcoal development has made breakthrough progress.

The rest is just minutiae, and there will basically be no problems.
