The Datang version of the mine test was successful, and Fang Yiai finally had a sense of confidence, the mines could be exploded, so as long as the iron-making technology was improved, the Datang version of the artillery should also be able to be made, although it was difficult, but there was always hope. There is a way that things are man-made, if you don't try, how do you know if you can succeed?

Not long after Fang Yiai and a few people left the small mound, more than a dozen Jin Wuwei came here, and the leader was actually the old monster Cheng Biting Jin. Cheng Biting Jin looked at the scene in front of him dumbfounded, and muttered to himself, "Good guy, no wonder the movement is so big, it turns out that the sky has fallen thunder!" ”

If Fang Yiai heard this, he would have to laugh, but it was no wonder that Cheng Yanjin said such a thing, Datang respected the gods very much.

This room bereaved love finally changed into clean clothes, and after the exquisite tidying, the whole person also looked cool, and there was no longer the sloppy image of a few days ago. Fang Yiai walked on the streets of Nanshi, followed by four beauties dressed as men. For Changle, Linglong and Qianqian women dressed as men, Fang Yiai didn't feel anything, but this Cheng Ling'er also played with women pretending to be men, which is a bit strange, but Fang Yiai didn't bother to care.

"Fang Jun, where are we going?"

Cheng Ling'er asked impatiently, if it weren't for Cheng Yanjin's bad idea, she wouldn't have bothered to dress up as a man.

"Ling'er, what are you anxious about, you'll know when you arrive!"

"Of course I'm not in a hurry, I'm afraid that the girl in your family is a little anxious!" Cheng Ling'er was particularly angry when she mentioned Yeli Liange, and she didn't know where Fang Yi'ai got the barbarian girl, she was even more barbaric than her Cheng Ling'er, no, she Cheng Ling'er was called arrogant, and the barbarian girl was called barbaric.

"I said Ling'er, don't talk nonsense, okay!"

"Hmph, I'm talking nonsense, princess, you have to take care of Fang Jun!" Cheng Ling'er saw that Fang Yiai didn't care at all, so she turned her head and said to Changle, who was snickering.

"Ling'er, okay, don't say it!" Changle shook her head and walked forward by herself, she lived a very easy life these days, she never thought that life could be so happy before, it turned out that after getting rid of those heavy shackles, she could also live that kind of happiness. At this moment, Changle felt that what she should be most grateful for was the eldest grandson chong who pushed her into the abyss, if it wasn't for the eldest grandson chong who made her fall into a state of mental death, how could she have the life she has now. Changle feels that he is lucky, the second son is a unique person, he can't see his arrogance in writing about the nobles, every day of life is dull, but it is also relaxed and happy.

After coming to the place where the paper was made, Feng Siliu had been waiting there early, and after seeing Fang Yiai, Feng Siliu said respectfully, "Boss, you are here!" ”

"Ah Si, let me introduce you, this is Changle!" Fang Yiai felt that Changle's identity should be told to Feng Siliu, and Fang Yiai also had his own ideas, the matter of papermaking here must always be handed over to a reassuring person, Feng Siliu's energy is limited, and it is impossible to run at both ends of Luoyang Chang'an. As for Zheng Liwan, to be honest, Fang Yiai was really a little worried about this woman, and until now he didn't dare to let Zheng Liwan know about the paper workshop. Thinking about it, Fang Yiai felt that Changle was the most suitable candidate.

"Huh? The small seal four willows, see Her Royal Highness the Princess! Feng Siliu was shocked now, he didn't expect this to be the legendary Princess Changle.

"Get up, you are the fourth Ah that the second son often mentions!" Changle was also very happy that Fang Yiai let her know more about him, just take this place as an example, Changle really didn't know that Fang Yiai let Feng Siliu run such a place, it didn't look like a restaurant, let alone a winery, but like a complex workshop.

"Ah Si, get up, take me to see the pulp pool!" After Fang Yiai waited for Feng Siliu to meet Changle's courtesy, he urged.

"Okay, please come with me!"

This workshop is very large, just a dozen pulp ponds account for the area of dozens of tents, but fortunately this is a relatively remote place, Dongcheng District has always been not very prosperous, and most of the people who live here are some ordinary people, so it is most suitable to build the workshop here.

After observing for a while, I saw Feng Siliu leading a middle-aged man in his forties over, this middle-aged man had a gray beard and was not too particular about his dress, but from his bright eyes, it could be seen that this person was a man with a strong chest.

"The owner, this is Master Zhao who is in charge of the workshop, he knows the things here best!"

"Grass people Zhao Rushan see the second son!" After Master Zhao saw Fang Yiai, he respectfully bowed, but he knew that those novel paper-making methods were all from the hands of this young man, just because of these, Master Zhao also had to say a word "service".

"Well, excuse me, Master Zhao, I heard Ah Si say that there are some problems in the workshop, can you tell me about it?"

"Second son, please wait!" Master Zhao left for a while and came back, still holding a stack of yellowed pieces of paper in his hand, he handed the paper to Fang Yiai and said, "Second son, you see, according to the method you said, papermaking is indeed much more convenient, and the output is much more, but how can this paper not be able to use the rice paper and paperweight used now!" ”

Fang Yiai touched the paper in his hand, and couldn't help frowning, this paper feels loose, just like the burning paper of later generations, not to mention writing calligraphy, it is estimated that it hurts to wipe his buttocks, this is not the paper he wants.

"Master Zhao, do you know what the problem is?"

"Second son, I'll tell you the truth, I've thought about this problem, it should be that the stickiness of the slurry is not enough, which causes the paper to be a little loose!"

"Sticky surname?" Fang Yiai handed the paper to Changle, who looked curious, and then he held his chin and thought, "Master Zhao, if you can solve the problem of sticking to the surname, shouldn't the paper you make better?" ”

"Yes, as long as the sticky surname problem is solved, then after drying, the paper should be smoother, more compact, and softer!" Master Zhao nodded and said with a serious face.

"Sticky surname?" Fang Yiai thought, how to solve this problem, he knows about rubber trees, but it is obviously unrealistic to use rubber as a raw material for papermaking, and the paper made in that way is estimated to be cheap, and it is good if it is not more expensive than the current paper.

"Master Zhao, have you tried to put some broken peaches or citrus in the pulp pool or something?"

Listening to Fang Yiai's words, Master Zhao fell into deep thought, he thought about it, suddenly his eyes lit up, and he said with a little excitement, "Yes, the juice of peaches is not low, why didn't I think of it, this should work, haha, second son, slack, I'm going to tell someone to collect some citrus and other things, although it's not easy to find these things now, but there should still be them!" ”

"Don't worry, Master Zhao, I will ask the shopkeeper Feng to send someone to transport some limestone, you pour the limestone into the pool when you pour it, there should be unexpected results!"

After Fang Yiai gave the order, Master Zhao couldn't wait to go somewhere else, probably to see if the problem of sticky surnames could be solved.

"Ah Si, when the results come out, you will immediately send someone to tell me!"

"Don't worry, I will stay in Chang'an in the near future, and I will inform you as soon as there is news!" Feng Siliu knew that Fang Yiai valued this papermaking workshop very much, and even looked at it as important as not returning drunk.

When he went back, Fang Yiai sent Changle to the princess's mansion with his surname, and when he left the princess's mansion, Changle still couldn't hold back after all, "Second son, are you really sure to make cheaper paper?" ”

"It should be possible!" Fang Yiai doesn't dare to pack tickets randomly, who knows what went wrong with this kind of thing.

"But, second son, you can't hide this kind of thing from others, if you let others know that you are running papermaking, there will definitely be a lot of ginseng for you!"

"Changle, you are really smart, so I have long planned to hand over the papermaking matter to others!"

Fang Yiai smiled mysteriously, and Changle's face turned a little red with a smile, why did the second son look at her like this, "To whom?" The lady of the Zheng family? ”

"She? Of course not, I'm not sure about that woman! ”

"It's not her, who's that?" Changle couldn't think of it now, it was impossible for Linglong to help him do these things, not because Linglong was not capable enough, but because his identity was there.

"Far away in the sky, close in front of you, Changle, who else do you say?" Fang Yiai looked at Changle and said with a smile.

"Me?" Changle pointed at himself and shook his head in a little surprise, these two sons are really shrewd, and they are all on her head.

"Changle, I have no other way, you should know that you are the most suitable!"

Fang Yiai said very sincerely, but it made Changle a little dazed, she is the most suitable? Think about it carefully, it's really like that, with the relationship between himself and the second son, he can really be regarded as the most trustworthy person, and the rest is the identity, just the identity of Princess Changle can bluff a group of people, it is estimated that there are really few people in Datang who dare to trouble Princess Changle. And the most important thing is that with Changle involved, I believe that when the time comes, Li Shimin will have to be dumb and can't say that he has suffered from Coptis chinensis, and his baby daughter has been mixed in, and when the time comes, when the imperial historians participate in the performance room and leave love, then he can only help wipe his buttocks.

"Second son, I found that you are so bad, you actually have a calculation on my father's head!"

"Changle, don't blame me, if you want to blame, you can only blame Your Majesty for being too greedy!" Fang Yiai said and remembered that when he first made wine, Li Shimin was not polite to him, and his mouth was hundreds of thousands of yuan, thinking about it, Li Shimin was really black enough, and he worked hard to make some money, Li Shimin was good at picking up ready-made. This time, let Changle mix with him recently, and see that he is embarrassed to ask his daughter for money at that time.

"Second son, how can you say that about my father?" Changle pouted and feigned anger rarely.

"Gas, gas! Changle, this son is gone, you are ready to be a good boss lady for me, hahaha! Fang Yiai snapped his fingers angrily, turned around and walked towards the outside of the house, even Changle ignored him, and walked unusually chic.

"It's so hateful!" Changle saw that Fang Yiai really left without looking back, and suddenly stomped his feet angrily.

"Hostess? Miss, what did the second son tell you? Seeing that Changle had stopped in place for a long time, Haitang asked with some curiosity as she walked over.

"Hostess? Hmph, you heard it wrong, he wants to be beautiful! Changle said, but there was a little happiness in his heart.
