Ma Jun made him, or to be improved ink charcoal to Wen Ren attack, and on the spot practice, the original combustion is not complete, can not play much role in the cold of the ink charcoal, but in the furnace burned violently, a few small pieces of ink charcoal, is not inferior to the same amount of firewood, of course, maybe the power of burning is not as big as firewood, but the problem is that in the cold winter season, in the border area, the use of such ink charcoal is naturally to pick up firewood is much more convenient.

Not all places, four seasons can find trees that can be cut down, mountains, rivers and rivers, when this era, is private, belongs to the fiefdom of the prince or the temple of the Son of Heaven, in addition, in the cold winter season, firewood is even more difficult to find, Ma Jun's ink charcoal, if it can be produced in large quantities, sent to the Quartet, obviously for the coming winter, there is a good resistance, however, if the cost is too high, for the common people, it is not a good thing.

As for how Ma Jun did it, how to make a small improvement to make the ink charcoal burn more powerful and laster longer, he didn't know anything about the attack, even if Ma Jun had explained it to him dozens of times, he was still confused, in order not to lose face in front of his disciples, he could only make a sudden realization, nodding, Ma Jun said with some joy: "This thing should be dedicated to the Son of Heaven!" ”

Wen Rensheng took this thing with him and went to the palace again.

Song Dian personally came out to greet him, the Son of Heaven saw that his health had improved, his heart was extremely happy, he took his hand, sat with him face to face, the two sat face to face, the Son of Heaven first asked: "Wen Rengong, is your body still healthy?" ”

"Thank you Your Majesty for your care, the minister is fine!" Hearing the attack, he replied.

The Son of Heaven nodded, and exchanged greetings with Wen Ren for a moment before asking, "Wen Ren Gong is here, I don't know what happened?" ”

"For this thing!" Wen Rensheng took out a thing wrapped in linen cloth from his arms, and gently opened it, revealing the piece of ink charcoal inside, which was pitch black, knotted, dark and shiny, the Son of Heaven looked at it seriously for a moment, and asked with some doubts: "Is this an ink stone?" ”

"Exactly, Your Majesty, do you know what this thing is for?"

The Son of Heaven laughed and said, "Don't underestimate me, I was poor when I was young, and I have seen this thing, this thing is placed in the furnace, burned with fire, and has the purpose of keeping out the cold, what I said is right?" Wen Renxing nodded and said, "That's right." ”

"Wen Rengong wants the court to use this thing?"

The Son of Heaven asked with some confusion.

"Your Majesty, the minister also knows that this thing burns very slowly, not as good as firewood, and it is extremely inconvenient to take, but it is the literati who love this thing a lot and carve it, but this thing is absolutely extraordinary, and it is made by Ma Jun, a disciple of the minister...."Hearing the attack, he talked about the various wonderful uses of this thing, and when the Son of Heaven heard it, his eyes suddenly burst into flames, and he hurriedly shouted: "Song Dian! ”

Song Dian hurried over, and the Son of Heaven pointed to this thing and shouted, "Bring a furnace here!" ”

It didn't take long for Song Dian to take a small hand-held furnace and put it outside the main hall, the Son of Heaven did not care about the emperor's prestige, took the ink stone in his hand, and threw it directly into the furnace, and it made people on fire, and it didn't take long for the furnace to burn flames, not very violent, but when the Son of Heaven stretched out his hands outside the furnace, he could still feel the heat, and the Son of Heaven grinned.

"Wen Rengong, how is this thing made? Can it cost a lot? ”

"It's... I have to ask Ma Jun. ”

"Then why didn't you bring him here?"

"He is a sinner, and he does not dare to come."

The Son of Heaven was stunned for a moment, and then remembered that Wen Ren had recommended Ma Jun, when Ma Jun was still a half-grown child, the Son of Heaven had already met him, remembering that in the past, he also wanted to carve words, the Son of Heaven shook his head and said: "If this thing can be of great use, I forgive its sins, and you quickly let people bring him...", Wen Ren Attack made a little embarrassed, and said: "I don't know in what capacity I brought him here..."

"Hahaha, you bring him first, enter the palace in vain, and you may not come out in vain."

Hearing the attack, he immediately sent someone to his home, and took Ma Jun to the palace, Ma Jun saw the eunuch who came, his heart was still a little nervous, he thought that the Son of Heaven would not summon him, and immediately made preparations, turned out the only clean clothes in the house, dressed neatly, and followed the eunuch into the palace, when Ma Jun stood in front of the Son of Heaven in a little panic, and bowed his hand, the Son of Heaven was still a little stunned.

He only remembered that back then, the timid and cowardly little guy, in a blink of an eye, this son has already been crowned, this day, it is really fast, the Son of Heaven sighed, looked Ma Jun up and down, and his eyes widened when he heard the attack, this guy who used to be gray and dirty, today he is wearing so neat and clean, alas, no, how can this set of clothes on his body be so similar to what he left at home?

Hearing the attack, the more he looked like it, Ma Jun glanced at him, and smiled a little embarrassedly, his own clothes were already dirty and messy when he did things before, if he came in that body, wouldn't it be disrespectful to the Son of Heaven?

The Son of Heaven asked, "Do you still recognize me?" ”

"Your Majesty, the minister dare not forget."

Ma Jun lowered his head and said.

"Oh, your mouth has become sharp, well, come on, tell me how this ink stone is made."

"Your Majesty. Your Majesty, the minister has burned all things with fire, some of them are burned early, the speed of burning is different, the minister has been tested repeatedly, if the ink stone is removed..."Ma Jun told it, the Son of Heaven's eyes widened, I really found myself guilty, this was the case with Liu Hong before, and the same is true for this guy, he doesn't talk about people, he was a little embarrassed and secretly glanced at the people on the side, this guy actually shook his head, and seemed to understand Ma Jun's words!

Tianzi coughed and said, "I see, but I don't know, the cost of production will be too high?" ”

Ma Jun looked at the Son of Heaven with some suspicion and said, "Your Majesty, I just said that you only need to smelt it simply..."

"Hahaha, good, good, if this thing is used to provide for the people affected by the disaster, and for the country and the people, it is a great good!" The Son of Heaven got up, walked to Ma Jun's side, patted him on the shoulder, and praised him a few times, and when the Son of Heaven finished praising him, his eyes widened when he heard the attack, it turned out that on Ma Jun's shoulder, two dark handprints were left, and the Son of Heaven obviously noticed it, and looked at his hands, his hands were pitch black....

"My clothes!! Your Majesty, this is left to the minister by the grandfather of the minister!! Hearing the attack, Tao shouted.

"Oh? Is it yours? Okay, don't do this, Song Dian, get some money for Wen Rengong later...."Song Dian nodded, the Son of Heaven asked him to take the money, naturally he didn't want him to pay the money, but to use the royal family's money, Wen Renzheng looked at the Son of Heaven with some grievances, and said: "In order to refine this thing, three houses in my house have been burned down, and now, my master and apprentice are two, and the family is surrounded by four walls, and there is not even a place to live..."

"Alas, I know, you go around Duke He's mansion now, choose a room, move in, I will let Song Dian accompany you..."

"Thank you, Your Majesty!" Wen Renxing smiled and nodded, and left with Song Dian.

The Son of Heaven watched him leave, shook his head a little helplessly, and said to Ma Jun: "Wen Rengong, he is extremely talented, but... It's a little stingy, but you have suffered by following him all day long..."

"Your Majesty, the minister did not suffer, and the master treated the minister very well."

The Son of Heaven nodded with satisfaction, respecting the teacher, and it can be used.

"It's just that, Your Majesty, the minister doesn't have a house to live in... I have been working for a long time to worry about the master, and the minister is panicked..."

"Okay, don't say more, hurry up and keep up with Song Dian... I want to cook the stove alone..."
