The next morning.

A carriage slowly entered the city, it was Qin Huaidao who drove the car, and the gatekeepers saw that the dignified Yiguo Gong actually drove the carriage in person, they were all a little confused, and hurriedly gave priority to release, Qin Huaidao also had no choice, Qinjiazhuang was far from enough, one person hated to be used for two, twenty-four hours a day, so he had to catch the car by himself.

However, Qin Huaidao is not a good person, it feels very interesting to drive the carriage, the horse is an old horse, he has a gentle temperament, he will not run around, but he walks slowly.

Entering the city, people came and went on the street, all busy with their own affairs, no one paid attention to Qin Huaidao, plus Qin Huaidao was wearing civilian clothes, not conspicuous, but it did not arouse onlookers, when passing a pharmacy, Qin Huaidao quickly stopped the horse, jumped out of the carriage and walked in.

"Guest, what do you need?" The shopkeeper greeted him warmly.

"Is there plaster?" Qin Huaidao asked.

After being free last night, Qin Huaidao reviewed the cement firing process and found that gypsum was also a problem, and he asked someone to inquire, but he didn't know what it was.

As everyone knows, the shop guy was a little confused, Qin Huaidao sighed, if he couldn't find the gypsum, the cement still couldn't burn the finished product, so he could only do the clinker step, and the semi-finished product could be used, a little loss, a flash of inspiration, is it a different name now, so he asked: "A white, stone-like thing." ”

The shopkeeper thought carefully and hesitated.

Qin Huaidao simply said, "In this way, you can show me all the medicinal materials that are similar to white stones." ”

The shopkeeper was very enthusiastic, went into the counter, opened some drawers and took out the herbs.

Qin Huaidao looked at it all the way, and soon found the plaster, and hurriedly shouted: "This is it." ”

"Guest officer, this is a fine stone, also called a jade stone." The shopkeeper reminded.

Qin Huaidao said indifferently: "You can call it anything, how many?" Give it all to me. ”

When the store guy heard that it was a big customer, he kindly reminded: "It seems that there is still a bag, is the guest officer going to use it to make tofu?" It doesn't take so much, a small piece is enough for a long time. ”

"Give it all to me, by the way, where do you get this kind of stuff from?" Qin Huaidao inquired that in the future, large-scale cement burning must be found, and where can I buy it in pharmacies.

The shop guy was not happy when he heard about the source of goods, and frowned and said, "Why is the guest officer inquiring about this?" If you need as much as you need, you can buy it. ”

Qin Huaidao reacted violently and asked rhetorically, "Are you shopkeepers here?" ”

The shopkeeper was silent with a cold face, and Qin Huaidao had no choice but to show his identity.

The token is a little domineering, the shop guy knows the words, he was startled when he saw the words on it, and looked Qin Huaidao up and down, although he was heroic, but this dress was too ordinary, and it was dirty, this is the unspeakably expensive Guogong?

Just as a patrolling Qianniu guard passed by, the shopkeeper rushed out and shouted: "Official, come quickly, someone is pretending to be the prince of the country, arrest him quickly." ”

When Qian Niuwei heard about the pretending to be the prince of the country, isn't this looking for death? Rushing into the store and seeing that it was Qin Huaidao, the former superiors were all startled, and hurriedly saluted, Qin Huaidao also couldn't cry or laugh, looked at the sluggish store guy and said, "Now believe it, right?" ”

"Are you really a national prince? But how are you dressed? The shopkeeper still couldn't believe it.

The leader of Qianniuwei was not happy, and scolded: "Dare to frame Guogong, do you want to find death?" ”

"Ah-" The shopkeeper reacted, Qianniuwei admitted that it was definitely yes, he actually reported Guogong, it was simply looking for death, and quickly apologized: "Grandpa Guo, the little one should be damned, the little one is innocent, and I ask the Guogong to forgive the crime, by the way, I heard that this fine stone is from Shannan Road, and it is not clear where the specific small one is, so I have to ask the shopkeeper." ”

"Then call your shopkeeper."

"Grandpa Guo, wait a minute, the little one will go." The shopkeeper hurried into the inner hall.

Qin Huaidao motioned for Qianniuwei to leave, and after waiting outside for a long time, a white-bearded old man hurriedly came out and saluted respectfully: "Grass people Zhang Cheng has seen Grandpa Guo!" ”

"My husband doesn't need to be polite, I'm bothered, this thing is really very important, and I ask my husband to tell me."

The old man named Zhang Cheng said truthfully: "This fine stone is produced in Xixiang County, which is under the jurisdiction of Yangzhou Prefecture in Shannan Province, and I heard that Yangyuan County also has it, and the specific situation is not clear. ”

"Thank you, uncle, let's take out as much as you have in the store!" Qin Huaidao said gratefully, wrote down the name, and remembered that South Zhongshan Road was the area of Hanzhong, south of the Qinling Mountains, a little far, this freight was a big problem, and couldn't help asking: "Is there no near Chang'an?" ”

Zhang Cheng recalled for a moment, shook his head and said, "I haven't heard of it." ”

A bag of gypsum is taken out and put on the car, the price is not cheap, it costs 500 Wen, if you buy it all from the pharmacy, the cost is too high, you can't afford it at all, you can only find a mine, but the cost of transporting it from Hanzhong will not be small, you must think of a proper way.

Qin Huaidao drove the carriage and thought as he walked, and unconsciously came to the gate of the imperial city.

The carriage was stopped, and it was Cheng Chubi who guarded the door, looking at Qin Huaidao, who was dirty, and was a little confused: "Brother, where did you come back from, what happened?" ”

"It's okay, I'm too busy during this time, I don't care about grooming, and I'm tired of it." Qin Huaidao jumped out of the carriage, and the carriage could not go in, so he could only walk.

Cheng Chubi called a person to give a few words, and after sending the other party in to report, he asked curiously: "I heard that you haven't been to the court for more than ten days, what are you doing?" ”

Qin Huaidao asked curiously: "There is something wrong in Qinjiazhuang, but Lord Fang didn't ask me for leave?" ”

"I heard that I was invited, but I didn't say the reason, the Ministry of Rites and the Yushitai jumped hard, saying that you have no court law and want to impeach and dismiss you." Cheng Chubi said with a smile.

Qin Huaidao was happy when he heard it, he didn't take it to heart, and chatted with Cheng Chubi for a few words, and the person who reported came out, accompanied by an inner attendant, followed the inner servant into the imperial city, and soon came to the Manna Palace.

After getting permission, Qin Huaidao entered the hall and saw that several ministers were discussing around the brazier, so he walked up and said, "Wechen has seen the saint and a few adults!" ”

"Why are you dressed like this?" Li Er frowned and asked, it is a sin to lose your honor in front of the king.

"Back to the saint, Weichen hasn't slept well in the past ten days, I'm not afraid of the jokes of the saint and a few adults, I'm too busy to even take a bath, I concentrate on developing things for warmth, and I ask the saint to forgive me." Qin Huaidao hurriedly explained.

"Isn't it developed?" Li Er's eyes lit up, and he left his dislike behind.

Fang Xuanling also got up, looked at Qin Huai eagerly, and said, "Come on, is it done?" ”

"Thanks to the Holy Blessing, it has finally been made."

"Great, where's the thing? Grab it quickly. Li Er shouted in surprise.

Qin Huaidao had no choice but to explain: "In the carriage at the city gate." ”

Li Er looked at Wang De and said impatiently, "Quick, pull things over." ”

Wang De didn't dare to slack off, and hurriedly ran out to make arrangements.

"Quick, give me a seat!"

Li Eryi thought that the heating problem was solved, and he was in a good mood.
