Seeing the empress coming, Lu Chen couldn't help but smile slightly.

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

Hearing this, the empress smiled knowingly.

"Really? That's good. ”

After the others reacted, they hurriedly bowed to the empress.

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

The others subconsciously retreated, keeping the distance between the monarch and the empress as they should be.

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

Anyway, the empress's favor for him has already gone to heaven, and it is not bad for this.

"Is this the detoxified carbon?"

The empress pointed to the charcoal in front of her and asked softly.

"Hmm."

Lu Chen nodded, and then instructed Su Ning to explain to the empress, I don't know if he was troublesome, or if he wanted Su Ning, a rookie who had already represented the way of things to some extent, to show his face more.

Su Ning glanced at Lu Chen gratefully, then organized the language a little, and then began to explain the techniques of harmless treatment of charcoal that they had studied during this time.

That is to say, using the principle of mutual growth and restraint of all things, first analyze why the combustion of coal produces a harmful smoke, verify its composition, and then prepare a cleaning agent that can dissolve its harmful components as much as possible, and finally sieve the carbon and dry it for later use.

And what they're doing now is the most critical step.

Verify whether the cleaned charcoal will still produce those harmful smokes.

If they succeed, it will be a milestone achievement for these cultivators who have studied the path of cultivation, and then if they fail...... Then I can only continue to study without sleep and food.

Although it was not Lu Chen who explained it personally, the empress listened to it seriously.

"I see."

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

Now that you're all set, let's light the coals. ”

"Yes, Your Majesty."

Lu Chen responded, and then opened the fierce fire fold very simply.

Whoa, whoa, whoa!

Fierce flames erupted from the mouth of the excerpt, and the scorching waves of air even emitted a strong fire-breathing sound.

In the next second, Lu Chen put the fierce fire fold under the barbed wire fence and continuously heated the charcoal on it.

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

It didn't take long for the fierce fire to exhaust the fire spirit power and completely extinguish it.

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

Seeing this scene, Su Ning and the others all raised their throats in their hearts.

Even the empress raised her eyelids, and her eyes showed a look of expectation.

A few breaths passed.

The charcoal is still burning steadily, and the air around it is getting hotter.

Half an hour passed.

The carboniferous has hardly changed, and the surrounding temperature has gradually stabilized.

The heat wave came one after another, and several officials of the Tiangong Division who were not very strong were sweating on their faces, and they subconsciously took off their thick coats, and the palace people behind the empress were like being in a furnace, and the whole person was panicked, and the cold brought by the cold snap that had gradually faded in recent days was also completely dissipated in this heat wave.

Their faces were full of disbelief, as if they could never have imagined that the ignition of charcoal could make the surroundings so fierce, and even the whole house became warm like spring.

It simply shattered their perceptions.

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

And the whole burning process, there is not a trace of smoke, and a trace of pungent smell is produced!

"Cheng... It worked! ”

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

She jumped up excitedly, and when everyone was still unable to recover from the huge impact, she suddenly hugged Lu Chen and said loudly: "Lord Lu, we have succeeded!" ”

At the same time, her eyes also turned red inexplicably, and the spiritual power in her body began to be crazy and restless, constantly impacting the spiritual veins, and the surrounding spiritual energy also began to pour into her body, quickly transforming into spiritual power under unconscious refinement.

Lu Chen: "? ”

Suddenly, nephrite was warm and fragrant, and he couldn't help but feel a little confused.

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

"Su Siye."

An inexplicable cold voice suddenly sounded, but it was the empress who opened her mouth expressionlessly:

"Pay attention to the courtiers."

The indifferent words made Su Ning startled, and hurriedly let go of Lu Chen.

"Hug ...... I'm sorry, Your Majesty, Wechen is so happy that he can't help it. ”

The empress raised her eyes and glanced at her.

Lu Chen cleaned up the wrinkles on his body a little, and when he saw that the empress seemed to have a more serious meaning, he said casually: "Your Majesty, Miss Su, they have been studying charcoal for a while, and now they finally have results, it is normal for people to be excited for a while, please don't be harsh." ”

Hearing this, Su Ning immediately looked at Lu Chen with a grateful face.

The monarch lost his honor, this matter is not big or small, it all depends on what the emperor thinks.

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

And Lu Chen, the big celebrity of the empress dynasty, spoke for her, and with the empress's trust in Lu Chen, no matter how unhappy she was, she would sell him a face and make this matter a big deal.

Sure enough, after Lu Chen's words fell, the empress's chest just rose and fell violently inexplicably, and the cold color on her face gradually disappeared.

"Lu Qing is reasonable, but Su Siye"

I saw her bow slightly, then turned her head, looked at Su Ning, and said indifferently: "This is the Tiangong Division, the yamen of the imperial court, and you are now an official of the imperial court, please be sure to abide by your duties, remember the courtiers, don't have any more outrageous behaviors, I can read that you are a first offender and don't care about you, but, there can be no second time in the matter of losing honor in front of the king, do you understand?" ”

Su Ning was like being amnestied, and hurriedly nodded heavily.

"Weichen understands, thank you for your forgiveness!"

At the same time, she couldn't help but complain in her heart, Lord Lu clearly said that His Majesty was generous and informal, she just couldn't help but hug Lord Lu just now, and she didn't mean to, and she didn't directly offend Long Yan, why is Your Majesty so serious?

It seems that His Majesty's generosity and informality are only for Lord Lu, and the others should do what they want.

After a small episode, the empress stared carefully at the burning charcoal on the barbed wire, and her nose did not smell any strange smell, and her eyes suddenly showed curiosity.

"Lu Qing, this specially treated charcoal, will there really not be any harmful smoke when burned?"

Lu Chen smiled.

"I'm not sure yet, but now that the pungent smell and smoke are gone, it should be about the same, and then, we just need to verify it with some ordinary beasts and measure other indicators."

Hearing this, the empress nodded knowingly.

It's true that this thing can't be launched right away until it's absolutely safe.

However, the coal has been burning for so long, and the people in the room do not feel any discomfort at all except for the heat, which is enough to prove that the process of coal development has made breakthroughs.

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

It can be done in a day or two at most.

Moreover, this charcoal burns much longer than charcoal, which has been more than two quarters of an hour, and the heat wave released has increased instead of decreasing, which is obviously more practical than charcoal.

Every year, I don't know how many people in Daxia freeze to death at home, and I don't know how many people in Daxia do not know how many, if this is large-scale development, the people of Daxia will completely get rid of the suffering of winter, and it will be just around the corner.

This is not only a huge amount of wealth, but also represents a great merit of life.

As soon as he thought of this, even with the empress's state of mind, he couldn't help but feel a wave in his heart.

After all, no one knew better than she meant to a monk, especially a being like hers with holy relics.

Although this merit cannot be enjoyed exclusively, she did her best to support Lu Chen, so that she could blossom and bear fruit now, so she naturally had to take a lot of credit, and Lu Chen also accounted for most of the rest of the credit.

Sharing merit with Lu Chen, how could she not want to?

"Start verifying right away."

The empress waved her small hand and said very decisively: "Improve the harmless treatment process of charcoal as soon as possible, and I want the people of Great Xia to use low-priced, stable and durable combustible materials as soon as possible." ”

"Yes, Your Majesty!"

The people of the Tiangong Division responded in unison.

Everyone's face showed irrepressible joy.

Then the empress opened her gaze sideways and looked at Lu Chen, the corners of her mouth raised inexplicably.

"Lu Qing, you are the greatest contributor to the matter of Tiangong Division and Shi Tan, you say, how should I reward you?"
