After Yuan Fang whispered a few words to the three brothers at the South Gate, he walked with them to the hut not far away, which was also the residence of the three of them, and after a while, in the inexplicable eyes of everyone, the three brothers followed Yuan Fang away with their respective luggage and a large pile of strange stones.

Lin Hai stayed in place for a long time before he came back to his senses, at this time Yuan Fang had already left the Ministry of Industry, looked at the blacksmith of the Chamber of Commerce who was dumbfounded and at a loss, Lin Hai ordered: "You do what Lord Yuan said first, and go to me if you need anything." After speaking, he strode away in a hurry, and ordered his subordinates to call the steward in charge of the purchase to check all the recent consumption of the three brothers in the South Gate, especially the ore and the like, Lin Hai faintly guessed that the reason why Yuan Fang changed color so much was definitely related to those strange stones, and he wanted to see what it was that made Yuan Fang care so much.

In addition to the Yamen of the Ministry of Industry, the group quickly stepped up, Yuan Fang was anxious, and he couldn't wait to share this great good thing with Yang Xing immediately, so that he could also be happy.

The three brothers of the Nanmen family rode behind Yuan Fang on horseback, surrounded by many female soldiers, just now, Yuan Fang said that their discovery, that is, about the matter of the stone, was a major invention, and they wanted to take them to see the emperor, and the three brothers who were a little excited at that time didn't think much about it and followed along with their luggage and all the things about calcining the stone according to Yuan Fang's request, and now they were blown by the wind, and they began to worry a little when they calmed down, worried that Yuan Fang would not be bad for themselves, I was worried about whether these stones had committed any taboo and were punished by the emperor, anyway, now the hearts of the three brothers are full of mixed feelings, and they want to ask, but they dare not ask.

Nanmen Yang and Nanmen Xing looked at the eldest brother Nanmen Tie, the two of them secretly observed Yuan Fang for a while just now, this Lord Yuan has been keeping a straight face after learning about that kind of stone, and he didn't say a word when he left the Yamen of the Ministry of Works, looking at the posture, it shouldn't be a good thing.

Nanmen Tie also found out about this, frowned and shook his head slightly, signaling the two brothers to calm down, things are already like this, it's too late to regret it, to be honest, Nanmen Tie regrets it, regrets it very much, he knew that it would be like this and killed him wouldn't mention that kind of stone.

The atmosphere was depressing, everyone remained silent, Sang Rou and Yuyue opened the way in front of the team, and pedestrians avoided left and right from afar, and the road was unimpeded.

Yu Xiaolou had a very comfortable and leisurely time during this time, Lin Hu and Qiao San, the commanders of the forbidden army in the imperial city, were transferred away to do things, Yu Xiaolou stayed alone, without restraint, free and easy, but his heart was bitter, to be honest, the palace was the center of power in the empire, and there were many big people in this errand, and there was almost no danger, and it was decent enough, but this place was only suitable for the elderly, as a soldier, the youngest soldier, as a soldier with a dream, it was a kind of torture to stay here, because there was no fight here, There is no fighting, it is a bit uncomfortable to be comfortable, it is basically impossible to make a contribution, although Lin Hu and Qiao San did not say what they were going to do when they left, but the joy on their faces It is not difficult to see that the two must have been entrusted with a heavy task, even if they do not die, it is fortunate to be able to leave this dull post, Yu Xiaolou is really envious.

According to the usual practice, Yu Xiaolou was bored on the wall of the imperial city gate in a daze, in the distance, the sound of rapid horses' hooves from far and near, Yu Xiaolou's body was shocked, full of hope to look around, when the horse team approached, Yu Xiaolou sighed in disappointment, not the rebel rebel he hoped for but Yuan Fang came.

Yu Xiaolou ordered someone to open the door and go down to greet him in person, others may not know, but he knows very well, how many privileges Yuan Fang has, the imperial city is no different from his own backyard for this guy.

Yu Xiaolou greeted him with a smile, thinking about whether to talk to Yuan Fang and ask him to help him change an errand.

Although he has the privilege of riding into the palace, Yuan Fang has almost never done that, unless there is something particularly urgent, he thinks that it is showing off, and he will invisibly pull hatred for himself, so every time he dismounts at the gate of the imperial city according to the trick and walks into the palace, this time, Yuan Fang is no exception.

Turning over and dismounting, Yuan Fang waved his hand to Yu Xiaolou with a smile and said, "General Yu is on duty today." ”

Yu Xiaolou approached Yuan Fang's close relatives: "Yes, no, I saw Lord Yuan coming over in a hurry, is there anything wrong with being in such a hurry?" As he spoke, he looked at the three brothers of the Nanmen family who were a little restrained.

Yuan Fang knew that it was the duty of the forbidden army to bring outsiders to attack that they needed to find out their identity and purpose, and they could only be allowed to let them go after getting permission, but Yuan Fang had also brought people in before, and the forbidden army would not stop them too much.

Yuan Fang was in a very good mood, put his arm around Yu Xiaolou's shoulders and said, "The three of them are blacksmiths from the Ministry of Industry, and I will take them to see Your Majesty to discuss important matters." Under Sang Rou's reminder, the three brothers of the Nanmen family took out their official seals and identity jade plates, Yu Xiaolou glanced at them, and ordered his subordinates to wave and let them go after ascending the throne.

Yuan Fang was just about to take someone into the palace, but Yu Xiaolou grabbed Yuan Fang again, his expression twisted. Yuan Fang wondered how the resolute Yu Xiaolou had become a shy big girl today, and knew that there must be something unspeakable, so he said to Jingqiu: "Jingqiu, you go in first, and I will arrive later." Yu Jingqiu nodded, leaving Sang Rou and Yuyue to protect Yuan Fang, and led the others into the imperial city.

Yu Xiaolou's personal soldiers hurriedly came over and handed a one-foot-long flat box to Yu Xiaolou, Yu Xiaolou pulled Yuan Fang to find a place where no one was, handed the box to Yuan Fang and said, "Lord Yuan, I heard that you like this thing, but I have been looking for a long time to find it." Yuan Fang tilted at Yu Xiaolou and began to mutter, what is the matter with this kid? I actually learned to give gifts.

Opening the box, Yuan Fang's eyes suddenly lit up, on the red brocade, there was a row of dark brown cylinders with thick fingers, without looking closely, Yuan Fang already knew what this thing was.

With a smile, he picked up one and sniffed it in front of his nose, couldn't wait to look left and right, and asked Sang Rou behind him: "Is there a fire?" ”

Sang Rou blinked her eyes inexplicably, took out a bamboo tube and asked, "Is this okay?" "This thing is specially used to start a fire, and it is coated with a soft core similar to phosphorus, and a light rub can produce an open flame.

Yuan Fang nodded vigorously, leaned over and lit the cigar in his hand, and took a hard breath, the rich smoke was inhaled into his lungs, a little choking, but it was very enjoyable, and he often breathed a sigh of relief, and the smoke poured out of his mouth and nose, Sang Rou and Yuyue couldn't help frowning, they finally knew what this strange thing was.
