When he heard that the old king said that the other party was sent by the Lu family mirage shop, Qin Fan understood the other party's intention.

After all, it's still the red eye disease!

Half a year ago, when Qin Fan took over, he clearly understood a truth: if you want to get rich, build roads first!

But how easy is it to build cement roads in Wannian County, which is short of finance?

So, Qin Fan conducted some research.

In Datang, most of the well-off homes will use two methods to build houses.

The first is a mortar of lime and sand, followed by the addition of yellow clay to increase the viscosity.

This is also the ancestor of cement concrete.

But after all, this ancestor was "born" early, so it is unsatisfactory in various performances.

Not only is the viscosity limited, but it is also very susceptible to water seepage.

Although the cost was low, Qin Fan vetoed it as soon as possible.

And the other way is related to the Lu family mirage shop.

The so-called "mirage" is a powder made from calcined oysters or clam shells to replace lime and be used in construction.

The "cement" obtained in this way has a good improvement in relative waterproof performance, but the defect is also obvious: expensive! Death is expensive!

Maybe to build a house, you need to calcine hundreds of thousands of shells to make up the mirage you need.

The manpower and material resources consumed can be imagined.

However, perhaps because the mirage looks relatively high-end, this building material is very popular among the top elites of the Tang Dynasty.

Therefore, this business is naturally controlled by Fan Yang Lu, who is in the position of "five surnames and seven hopes".

However, using mirage, Qin Fan didn't think about it at all.

Joke! I just want to build a road, not a palace!

The mirage is quite high, but to put it bluntly, it is calcium oxide with high purity, and the composition of ordinary lime cannot be said to be almost the same, it can only be said to be exactly the same!

Iron Iron IQ Tax!

Of course, Qin Fan can also choose a third material: glutinous rice lime mortar.

Needless to say, the performance of glutinous rice lime slurry is the best material for building city walls in ancient times.

But the disadvantages are also obvious: it is still expensive!

And it's more expensive than mirage.

Mirage only needs to collect shells from the beach for calcination.

However, glutinous rice needs to occupy good paddy fields for planting.

Moreover, the yield of glutinous rice is far inferior to that of rice, and planting glutinous rice can be regarded as a loss-making business!

Therefore, unless it is for the construction of a wall to defend against enemies, even the royal family and nobles generally do not use this material.

And Qin Fan, naturally, would not think about it!

The three materials were not suitable, and Qin Fan could only focus on the system.

Fortunately, the system happens to have a calcination method for cement, and it is very cheap to exchange points.

Qin Fan exchanged it for use, and the effect was very good!

Not only does it have the advantages of mirage, but its cost is one-tenth of that of mirage.

It can be said that Wannian County has had such a development in the past six months, and the material of cement has contributed a lot.

However, Wannian County is building such a large number of buildings, how can the Lu's mirage ash shop located next door be unaware.

When they found out that Qin Fan had invented a material that was superior to mirage, but the cost was only one-tenth of mirage, how could they not be impressed!

So, there is today's scene.

……

"This Qin County Commander will not apologize to our Master Lu! Don't even think about starting a private school! ”

A sharp-beaked monkey-cheeked ruffian picked his teeth with one hand and pointed at the angry servant with the other.

"This is a private school built by the government, aren't you afraid of being arrested?"

A young catcher glared angrily.

"Yoh? Catch me? ”

The ruffian was immediately happy.

"Come, come, come! Put shackles on me. Wait! ”

Catch quickly, even if you have to bring a wooden flail, arrest the other party.

"Junko!" Zhong Xuan, who was behind him, patted the young man on the shoulder and shook his head.

"Head! They're all so arrogant! ”

Zhong Xuan tore off the wooden flail in the hands of his juniors and said:

"These are Lu's subordinates, as the saying goes, it depends on the owner to beat the dog!"

That straight blood is on the head! Suddenly shouted:

"What about the Lu family? Can the Lu family still manage my master? We are Wannian County here! ”

Zhong Xuan frowned and drank: "What are you talking like?" The old king has already gone to call the master to come over, and you will only cause trouble for the master now! ”

"What's the trouble? Junko was right! These guys are hindering the construction of this county, and they are caught! ”

A voice came from behind Zhong Xuan.

"Sir! They were sent by the Lu's Mirage Shop in Chang'an County! Zhong Xuan whispered to explain the origin of the other party.

Qin Fan also understands that Zhong Xuan's subtext is nothing more than that: the five surnames and seven hopes are not easy to provoke, and if they can take a step back, they will take a step back.

"What about the Lu family? These dogs are obstructing the construction, and it is reasonable for this official to detain them for three days according to the laws of my Datang! Come on, catch me! ”

"Yes!" Seeing that Qin Fan's mind had been decided, Zhong Xuan didn't say anything more!

Since the county lord is so calm, he must have confidence, and there is Lord Qin behind him, what are he afraid of?

One kind of catch quickly swarmed up and arrested that line of ruffians and hooligans together.

Of course, because of the other party's arrogant actions before, in the process of arresting, because the prisoners resisted, it was reasonable for the arresters to start a little heavier.

……

Luguo Mansion.

"Is this cement really that valuable?"

Hou Junji looked at the brocade-robed boy in front of him and his eyes widened.

Lu Kuan shook the folding fan lightly and said with a smile: "How dare the little nephew lie to Uncle Shi!" Cement is much better than my mirage! It is conservatively estimated that it can also make a profit of hundreds of thousands of taels of silver a year! ”

"That kid really doesn't have a backstage?"

"Uncle Shi rest assured, the little nephew has been eyeing that kid in Wannian County since half a year ago, and in the past half a year, I haven't seen him interact with other officials at all, and he has always been just a lucky guy!"

"Now that the men I sent out have been taken down by that kid, let's take advantage of the problem! It's easy to get the method of firing cement! When the time comes, all the silver will fall into the pockets of you and me, wouldn't it be wonderful! ”

As soon as I heard that Qin Fan was just lucky to become an official, he had no background.

And the eldest son of the Lu family has already arranged everything.

Hou Junji immediately made up his mind and took care of it:

"Now that the virtuous nephew has arranged everything, then Uncle Shi will also make a contribution, but the share, I think we can discuss it again!"

……

"Childe! That Hou Junji was too greedy, just taking the lead in impeaching a small county order, and he actually opened his mouth to share fifty percent of the proceeds! ”

Coming out of the Luguo Mansion, the old housekeeper of the Lu family expressed his dissatisfaction.

Lu Kuan smiled slightly: "Your Majesty has a long-standing grudge against our family, and this time let Hou Junji open his mouth, just to probe His Majesty's bottom limit." As for the cement business, it was divided and divided. My Lu family is not short of this money! ”

"Childe is wise!"
