Ma Chao strode to the forging house and smelled a familiar smell.
Seeing that the forging house was tightly blocked, Ma Chao already had some concerns in his heart.
"Those four craftsmen were smelted in this closed room."
Ma Chao turned around and asked.
"Yes, young master."
Pu Yuan replied sadly, thinking that Ma Chao was just moved by the scene.
"Open the door."
Ma Chao ordered.
"Young Master, no, there is an innocent soul staying in this house.
No one can enter until seven days have passed."
Zheng Hun's face was tense.
Listening to his words, it seemed that he still had a lot of superstitious thoughts.
"Open it, those four craftsmen are still trying to kill me."
Ma Chao said sternly: "Open it, I want to go in and take a look."
Pu Yuan saw Ma Chao's fierce look and didn't dare to hesitate.
He stepped forward and opened the door.
As soon as Ma Chao entered, a strong smell hit his face.
Pu Yuan covered his mouth and nose, and the sight of his eyes made him scared: Ma Chao actually strode in.
"Young master, you can't."
Pu Yuan stretched out his hand to pull, but the pull was empty.
Ma Chao had already strode into the house.
"Young Master," the craftsmen watching outside all exclaimed in surprise, looking into the room with wide eyes.
Han Ying gritted his teeth and ran in first, while Zheng Hun and Pu Yuan were stunned, and then quickly followed.
The room is not big, and there is a strong smell of carbon monoxide.
In the smelting furnace, there are some half-white and half-black stones among a pile of gray-white powder, and under the furnace, there is a large pile of unburned black stones. .
Ma Chao picked it up and took a closer look.
It turned out to be coal.
He felt ecstatic in his heart, but immediately became nervous: "Open all the doors and windows quickly to keep the room ventilated."
No one knew what he meant, but seeing that Ma Chao's tone was unquestionable, Han Ying, Pu Yuan, Zheng Hun and others quickly moved to open the doors and windows.
Suddenly, a breath of early winter blew in, making the four of them shiver faintly.
However, this way, the feeling of nausea, vomiting, and dizziness when I came in was much relieved.
"Did the four craftsmen have headaches, shortness of breath, and convulsions before they died, and did their faces turn purple after they died?"
Ma Chao asked Pu Yuan after the three of them opened the window.
"How did the young master know?"
Pu Yuan and Zheng Hun were shocked.
Ma Chao was talking about this situation just like Qin Jian.
At this time, Ma Chao was convinced that these four people died unjustly and died of carbon monoxide poisoning.
But so what, the four living lives were gone after all.
Even though Ma Chao discovered the answer to this mystery, he couldn't bring the four people back to life.
However, one thing is certain, I can no longer let these craftsmen be superstitious.
"This coal is not used in all smelting furnaces.
Why is it not smelted outside, but in this hut?"
Ma Chao picked up the coal and asked with a frown.
"Young master, I don't know.
This beast charcoal has already been discussed in ancient books.

When used in smelting, the temperature is extremely high and lasts for a long time.
However, this beast charcoal is black and ominous and highly poisonous.
The user must take his life as a guide.
Come here, my subordinates.
In order to keep it secret, and secondly because of luck, I wanted to see if the beast charcoal could be used in this smelting."
Pu Yuan said, and couldn't help but kneel on the ground again.
To be honest, it was because he was greedy for success and wanted to get the fine steel as soon as possible that he did what he did.
"You mean, only this small smelting furnace uses coal and animal charcoal, while the other outer smelting furnaces use wood."
Ma Chao was a little angry now: He took it too much for granted.
Modern people take it for granted.
Coal has long been familiar to me, and I didn't know much about it.
However, I didn't expect that the craftsmen in the late Han Dynasty didn't know the function of coal.
"Yes, that's exactly the case."
Zheng Hun replied.
"Then where does this coal come from?"
"There is a mine in Xinping County, and Master Han Feng escorted a batch back to be used to suppress smoke at the beacon mouth.
My subordinates were bold, so they borrowed some from Master Han Feng."
This was Pu Yuan's answer.
But Ma Chao didn't know what to say at this time: when he saw craftsmen burning wood before, he thought it was because he couldn't buy coal, or there was no coal in Yongzhou.
But he never thought that this black gold was actually under his control.
However, this wealth did not bring any benefit to him, but it cost him four lives first.
Coal and iron have always been important strategic resources.
In ancient times, this black gold was actually covered with a layer of superstition, which frightened the ancients from getting involved.
It was really a huge tragedy, but it was precisely this that allowed me to take advantage.
In addition to being used for smelting, this coal can also be used for civilian purposes.
If this coal production is sufficient, then the problem of freezing to death and frostbite this year can be easily solved.
Thinking of this, Ma Chao was heartbroken.
However, getting these people to accept coal and dare to use coal is probably still a big project.
The only way is to try it yourself.
As General Pingxi, I am afraid that I can still convince some people.
"Although you two have smelted this peerless sword, the method you used is really wrong, and you lost four lives in vain.
The merits are not worth the effort.
Pu Yuan will be demoted to the next level, and Zheng Hun will have his salary reduced for one season.
You two Are there any doubts between the two?"
Thinking of this, Ma Chao first told the verdict of Zheng Hun and Pu Yuan, and then planned to go to Han Feng and ask him to introduce the situation of the coal mines in Xinping County.
"I accept my punishment."
The two of them had long since been convinced when they saw Ma Chao cutting off his hair and acting as the head, but at this time, they had no intention of seeking credit at all.
"Don't be discouraged, you two.
I still have two drawings here.
If you two can make up for your mistakes, I will not only exempt you from this punishment, but also reward you as appropriate.
But remember, this incident should be taken as Be careful, don’t let the Blood and Tears weapon appear again.”
"Nuo" Zheng Hun and Pu Yuan took the drawings and bowed to leave.
"Let's go find Han Feng."
Ma Chao turned around and said to Han Ying, but saw that Han Ying just looked at him blankly, showing signs of being crazy.
"What's wrong?
Free novels bring you joy and joy ---> storyskyline.net
I'm really possessed by a demon."
Ma Chao was good at shaking his hand back and forth in front of Han Ying's eyes, and only then did Han Ying react.
He hurriedly opened Ma Chao's hand and said angrily: "Stop making trouble, let's go.
Going to find Mr.
Han has nothing to do with Mr.
Han."
As he spoke, his face turned red.
"What's wrong?
Have you fallen in love with Han Feng?"
Ma Chao was surprised, why did he blush?
Naturally, he didn't know that his previous revelation of true feelings, coupled with the act of walking into the house regardless of his own safety in order to pay homage to the place where the four craftsmen died, were really an expression of the deepest affection in the girl's heart.
In the end, Ma Chao made a fair decision, which made Zheng Hun and Pu Yuan bow their heads and accept the punishment, showing their clear leadership style.
Han Ying had long been attached to Ma Chao, how could he not be obsessed with it at this time?
"What if you are seeking death?"
How could Han Ying not be angry when she heard Ma Chao teasing her like this.
And Ma Chao didn't feel embarrassed, but when it was time to close the door, he silently said to the four craftsmen in his heart: "Good friends, have a good journey." s: No one can reward me any more, so that I can be moved again:
