On the second day, Lin Zifan held the vernier caliper, and the corners of his mouth rose slightly.

"With this thing, they can't still make grenade parts that are so different in size, right?"

Ancient people, it's normal to have a little gap, but there is so much difference, it can't be used at all, but Lin Zifan didn't expect it before.

Time passed, and on the evening of the fifth day after receiving the task, Lin Zifan finally waited for the good news!

"My lord, fortunately, I don't disgrace my life, rubber...... Found it!"

Xiong Chumo returned, and she was followed by a group of soldiers, each carrying a large bucket, and inside the bucket was cut rubber!

"Good!"

Lin Zifan was overjoyed: "It's not too late, it's just right!"

With rubber, you can make rubber water pipes, faucets and other things, not only manhole covers can be solved, but even tap water, it can be said that as many as eighty percent of them have been completed!

This night, the logistics house was brightly lit and busy.

In the early morning of the second day, on the streets of Chang'an, the 'deep pits' that had existed for several days were suddenly covered with black manhole covers.

In order to block the curiosity of the Datang women, Lin Zifan also tried his best to 'scheming', and even added some dust to the milky white rubber to make it look as close to the asphalt road as possible, so as not to be too curious and spoil it......

......

"This pit is gone?"

In Chang'an, in an alley with a small flow of people, two women stood next to the manhole cover, looking surprised.

"Hey, I've been paying attention to this pit for the past few days, and it's suddenly gone, and I'm still a little unaccustomed to it?"

"You prodigal hoof, aren't you used to running out of pits, so you don't have a place to throw, don't think I didn't see what you did yesterday......

"Phew, as if you didn't throw it away!"

"Hmph, what's the big deal, if you don't throw it away, you won't throw it away, there is still a pit in my kitchen, go home and throw it away......"

......

"What is this?"

"It feels so weird, you go up and jump twice?"

"Why don't you go? The man just said that if it is broken, pull it back and hit the twenty boards!"

"Cut, everyone is gone, I'm afraid of a fart! Besides, the twenty boards, can't we bear it?"

"That's right...... What about trying?"

"Let's go, try!"

The two girls walked and stopped on a manhole cover one after another, and even stood on the manhole cover and jumped around......

Bang bang bang......

"It's fun!"

"Hey, this thing has elasticity, I jump up, fall, can bounce up quite high~!

"Really, I'll try!"

Bang bang bang......

"It's not going to be bad!"

"What are you guys playing? I'll ...... too."

Bang bang bang...... Boom......

"Damn! this thing is cracked, where's she?"

"Fell ......"

"It's not good, the Praetorian Guard is coming, run!"

"Sisters, ask for more blessings, I'll flash ...... first"

......

On this day, dozens of manhole covers were devastated......

For this reason, many of them were caught by the Praetorian Guards and beaten with boards, and there were even some unlucky ones, who first fell into the sewers, got gray faces, and were dirty, not to mention, and were especially caught and beaten with a board......

Fortunately, there are enough manhole covers. Although the curiosity of the Datang woman is strong, it has not been completely destroyed......

In the early morning of the seventh day after receiving the task, Lin Zifan woke up from his dream and finally breathed a sigh of relief.

Mission accomplished!

The manufacturing technology of composite manhole covers (in line with the current level of the times) has also been obtained......

For breakfast, Lin Zifan was still accompanying the empress in Qifeng Pavilion.

And Ziyi was talking about the interesting things that happened yesterday, and when Lin Zifan learned that someone broke the manhole cover and fell into the sewer, he got dirty, worse than a beggar, he couldn't help but be slightly surprised.

"You mean, the sewers are dirty right now?" he asked.

"Yes, Lord Lin!" Ziyi nodded: "It is said that many people are now throwing things into the pit, that is, into the sewer, and throwing all kinds of dirty things into it......"

"For example, in order to ensure cleanliness, no matter whose mount pulls down the feces on the street, they need to dispose of it themselves, otherwise they will be fined some silver. ”

"But mounts are generally pulled more, and they are dirty, smelly, and troublesome to handle......"

"But I heard that now, many people have learned to be smart, and after the mount pulls the dung, they just find a pit and throw the dung into the sewer, and everything is fine. ”

"There are even people who take their mounts directly to the edge of the pit and let them pull them into the pit......"

"In addition to that, a lot of leftovers that have gone rancid, etc., ......"

While Ziyi was speaking, the corners of the empress's mouth twitched one after another, and her eyelids jumped. The sewers haven't been repaired yet, and they're in ruins?

She even wanted to give the order to arrest those people and beat them up!

Lin Zifan was quite surprised, and there was no anger at all.

"Tsk, people's brains are really a good thing, and before they have been taught, they have already discovered the benefits of sewers? ”

"Lord Lin, aren't you angry?"

The empress and Tsing Yi Ziyi were stunned......

"What am I angry about?" Lin Zifan smiled dumbly: "Sewers are originally used to treat excrement and domestic sewage, etc., and there is nothing wrong with their usage." ”

"And if the excrement and sewage are discharged into the sewer, the cleanliness of our Chang'an will rise sharply, and all kinds of diseases will be effectively reduced, with many benefits~"

"In addition, if Your Majesty thinks it is possible, you can also levy a 'garbage disposal tax' like every household, eh...... It can be seen as the money for pouring night incense, after all, after the sewer is completed, they don't have to bear this cost at all. ”

"It's just that the sewer is not yet complete. However, Your Majesty, the minister feels that it is still necessary for you to issue a decree that excrement and sewage can be discharged, but larger and harder objects, such as bones, clothing, and other waste, must not be discharged!"

"Otherwise, once the sewer is clogged......"

Lin Zifan's mind made up that picture, 'The city is full of golden Xiang?'

It's unacceptable to think about it.

"That's fine, but what is the 'garbage disposal tax', in my opinion, let's forget it. ”

The empress is not interested in the garbage disposal tax, although she is poor, don't forget, the people of the Tang Dynasty are even poorer...... It doesn't seem to be any good to earn this money.

"Your Majesty has the final say. ”

Lin Zifan nodded with a chuckle, the garbage disposal fee, there is nothing wrong with not collecting it, anyway, there is a more profitable deal waiting for our empress after that, I am not afraid that the empress will have no money......

In fact, Lin Zifan has always had a small goal in mind, that is...... As soon as possible, we will raise our empress into a little rich woman~

The kind that doesn't have to worry about money anymore!
