The horse-drawn carriage drove slowly on Donghuamen Street in the rain, and the rain washed away the shops along the street. Pedestrians hurried forward with umbrellas and robes.

On the carriage, Zhao Hao pouted Pan Ji and said: "This is produced in Xishan, Beijing, not our Xishan in Suzhou, what is the difference between you and us?" ”

"Oh?" Pan Jitao really became interested, licked it first, and then clicked and bit down on the next piece. After closing his eyes and chewing carefully, he opened his eyes for a long time and said: "This product is purer, more punchy and crispy, delicious, really delicious, this is what it looks like!" What are the things you got in Suzhou? Full of scum! ”

Zhao Hao smiled and nodded, not surprised by Pan Zhongcheng's evaluation.

Unlike Jiangnan, which is poor in minerals, lime is not uncommon in the north.

Old Beijing jokingly said that there are two roads in Xishan, "black and white", black is coal, and white is limestone. The whole West Mountain is full of limestone, and the reserves and quality are far beyond that of Suzhou West Mountain. There have always been lime kilns in history, and at the beginning of the Lugouqiao Coal Yard, a large number of slaked lime from Xishan was purchased to remove sulfur from coal lotus.

Zhao Gongzi had already instructed Tang Fatzi to secretly acquire a number of lime kilns in Xishan. What Pan Jitao tasted was the raw materials he was going to use to burn cement for Xishan Company.

Pan Jitao naturally understood Zhao Hao's intentions, and couldn't help but look gloomy, feeling that the limestone in his mouth was bitter and astringent, and it was not so delicious anymore.

He threw the remaining limestone back into the small box, handed it back to Zhao Hao, and said, "I don't need cement here, and the plan to bundle water and wash sand has been rejected." ”

It's not that Pan Ji tamed the broom and cherished his own cautious eyes, and refused to take out the secret weapon to share with Zhu Heng and Weng Dali. However, because the Yellow River is an above-ground river, the embankment is several zhang above the ground, and the current process cannot directly replace the earth embankment with a concrete embankment. If it is like Kunshan, if the embankment is built outside the embankment, the amount of cement required will not be produced by Zhao Hao for ten years.

In the final analysis, the flow of the Yellow River is 200 times that of the Wusong River, so the experience of building embankments in the Yellow River can be used in the Wusong River. However, the experience of building embankments in the Wusong River could not be moved to the Yellow River at all.

Therefore, unless Pan Jitao's method is chosen, first repair the old road of the Yellow River with cement, and then pick up the embankment to flush the water, it is still the earthen embankment that is more suitable for the Yellow River.

Zhao Gongzi pushed the locket back into Pan Jitao's hand and said with a smile: "Who is Zhongcheng?" How can you be overwhelmed by a momentary setback? I believe that the Ming Dynasty can cure the Yellow River, it is none other than you! ”

"Oh?" Pan Jitao still values Zhao Hao's words very much. Hearing this, I couldn't help but expect: "Why, do you still believe in the old man's method of harnessing water and attacking sand?" ”

"Of course, you are my great water god, and no one in this world knows how to control water better than you!" Zhao Gongzi nodded heavily, and said in his heart After all, four hundred years later, people are still using your method of harnessing water and attacking sand to govern the Yellow River.

"So, the old man's method is very scientific?" Lao Pan couldn't help but look uplifted.

"Science, very science!" Zhao Gongzi smiled and gave a thumbs up.

"I'll just say it," Pan Jitao took out the ore that Zhao Hao gave him last time from his arms, threw it into his mouth and chewed it. Then it magically cheered up. "How can there be a mistake in what the old man has studied repeatedly?"

"The truth is often in the hands of a few." Zhao Gongzi sweated slightly, he just wanted to let the human meat analyzer, oh no, Pan Zhongcheng tasted it, he didn't let him eat it as a jelly bean!

The master of water control in the Ming Dynasty will not die of excessive heavy metals, right?

Zhao Gongzi couldn't help but secretly decided to try to get some safe ores for him to use as snacks in the future.

But where is there any ore to eat? White quartz, gypsum, mica, mineral salts? I'm tired of eating all these things. Premature life!

~~

Zhao Hao was thinking wildly, the carriage stopped at Lumicang Hutong, and Zhihua Temple arrived.

"Why don't you go in and sit?" Pan Jitao asked Zhao Hao.

"If I don't enter the temple, I will be dizzy when I see the monk." Zhao Hao shook his head and said with a smile: "If Zhongcheng still wants to go back to Suzhou, our fleet will return tomorrow, and we can give you a ride, first class, a lot of money." ”

"I got it." Pan Jitao shook his head and said, "Wouldn't it be a joke to go back so soon?" ”

"How so? Everyone wishes you would go back to the town quickly. Zhao Hao said with a smile: "There are still countless embankments in the south of the Yangtze River, all waiting for Zhongcheng to plan." ”

"Those things are too simple, your uncle can handle them." Pan Jitao couldn't help but smile, his days in Kunshan were still quite pleasant, at least everyone took his words as a guideline.

"The old man wants to challenge the high difficulty, and he will follow Zhu Hengnan to investigate the Yellow River, but they will not dare to chase me."

"Then I'm afraid this trip won't be too pleasant." Zhao Hao couldn't help but smile bitterly, this old man was like a child.

"That's right, you can't let the old man be unhappy alone." Pan Jitao laughed and got out of the car, waved at Zhao Hao, and strode towards the temple gate.

Pan Dafu gave a deep salute to Zhao Gongzi, he was a student of Yufeng Academy, and he took a leave of absence to take care of the old man.

Zhao Hao smiled and nodded at him, and Pan Dafu hurriedly held up the umbrella and turned around to chase his father.

The carriage slowly drove away from Lumicang Hutong, but did not return to Zhaojia Hutong, but went straight out of the city and came to the Datong River Wharf.

Jiangnan Shipping's fleet has finished its rest and will leave for its return early tomorrow morning.

Zhao Hao is here to see him off.

~~

Knowing that he was coming, Chen Huaixiu waited on the dock with an umbrella.

When Zhao Hao jumped out of the carriage, she greeted him with a smile and held an umbrella for him to protect him from the rain.

"Sister Huaixiu has been waiting for a long time?" Zhao Hao greeted Gang Leader Chen with a smile.

"I just came over, too." Chen Huaixiu smiled and shook her head, she didn't wear ...... When she was on the boat, she wore a smart samurai robe, but changed into a lake blue skirt, and only wrapped her head with a light blue shoukera to show the difference between her and the girl.

"Refreshments are already on board."

"Let's not get on the boat first." Zhao Hao stretched his waist, took a deep breath of the fresh air in the rain and said, "Let's go, I'm bored in the car." ”

Chen Huaixiu naturally did not agree, held an umbrella for Zhao Hao, and followed him forward.

"It's supposed to be a man who gives an umbrella to a woman." Zhao Hao took the umbrella from her hand, although Chen Huaixiu did not let the women shave their eyebrows, the petite Jiangnan women were always more able to inspire people's masculinity.

Chen Huaixiu pursed his lips and smiled, and let him be. Zhao Gongzi, who left Jiangnan, has obviously retracted his aura a lot. It seems that from the big boss of Jiangnan Group who pointed out the country, he has changed back to a sixteen or seventeen-year-old boy.

It's a good feeling too.

The two of them walked aimlessly along the stone road, and unknowingly came to the Odori Bridge.

I don't know if it's because of the rain, but the business of the rice shop on the side of the Chase Bridge has been a lot colder. Anyone who buys rice can go into the store, and there is no longer a long queue.

Zhao Hao even saw that there was a family called 'Huge Rich Rice Shop', which actually closed down.

"It seems that the rice shop business is not easy to do." Zhao Gongzi sighed casually and asked, "What is the price of rice now?" ”

"Today's rice price is one, two, five." Chen Huaixiu replied softly. After hesitating, she didn't tell Zhao Hao that the closure of this rice shop also had something to do with them.

"That's a lot down." Zhao Hao was deeply pleased, he didn't expect the effect he had done so easily.

If a stone of rice is sold for one or two or five silver, a pound of rice is ten cents, although it is expensive enough, but it is within the affordability of the people in the capital.

"Those Mi Xing people hate us to death." Chen Huaixiu said with a wry smile: "I caught a few people who wanted to set fire to the ship the night before yesterday." ”

"Oh?" Zhao Gongzi was slightly surprised, but he didn't hear the report. "Who is so bold as to dare to move the fleet of the eldest princess?"

"It's all improvised gangsters on the street, and they don't know who instructed them." This kind of thing is used to the Sand Boat Gang, and Chen Huaixiu can handle it himself. Of course it won't disturb Zhao Hao, doesn't that make him look down on him?

"If you encounter this kind of thing in the capital in the future, you ask Tang Youde to find Father-in-law Ji, and you will be sure that there will be no more blind ones." Zhao Hao reminded Chen Huaixiu.

"Remembered." Chen Huaixiu pursed his lips and smiled, his eyebrows flowing, revealing a charming look. Obviously, it has been handled properly in the way of the Sand Boat Gang.

"Before setting sail tomorrow, put out the banner of being ordered to transport grain." Zhao Hao commanded with some anxiety: "Otherwise, I'm worried that the Caoyun Yamen will make trouble for you." ”

The fleet of Jiangnan Shipping from the Datong River to the mouth of the Sancha River in Tianjin is under the jurisdiction of the Caoyun Yamen. Before, their fifty grain ships entered Beijing, and they must have been targeted by the Caoyun Yamen. There was no eldest princess on this return trip, and Zhao Hao was very worried that Chen Huaixiu and his party would be in trouble.

"I've already sent someone to sweep the river first, saying that there is a gate to make it difficult for us." Chen Huaixiu said softly: "But we didn't carry goods either, and they could only watch." ”

It is said that Beijing is the commercial center of the north, and there are all kinds of things that are scarce in the south of the Yangtze River, such as grassland furs, ginseng, deer antler and bear paws outside the Guan. As long as it is trafficked back to Jiangnan, it can easily make a profit of one or two times.

But Zhao Hao was worried that the Caoyun Yamen would meet the wealth, so he instructed Chen Huaixiu to leave the capital by empty ship and buy goods in Tianjin Wei, but the number of types is not as rich as in Beijing, but it will be cheaper.

As for the so-called 'sweeping the river', it is the black language of the Sand Boat Gang. It means that before the departure of the large army, the elite personnel will be sent in advance, and the wind will be heard along the way to clear the obstacles.

Although the Sand Boat Gang usually operates on the Yangtze River, they have hardly ever been to the North Canal. However, Wu Kee has been immersed in this canal for more than ten years, so he helped the brother company to take on the errand of 'sweeping the river'.

"Let's use the banner of the palace, forgive them and don't dare to mess around, at most disgusting and disgusting you." Zhao Hao couldn't help laughing at himself when he heard this, whether it was Wu Ji or the Shachuan Gang, they were all old rivers and lakes, and they didn't need to worry about him, a rookie boss, at all.

While talking, the two returned to the dock, Zhao Hao handed the oil-paper umbrella back to Chen Huaixiu, waved at her with a smile, and said, "Sister Huaixiu, see you next month." ”

"Childe, see you next month." Chen Huaixiu also smiled and blessed him.

ps. third more. Also, have a day off on Saturday and see you on Sunday!
