The Spanish fleet arrived at the port of the Chinese imperial court again. The customs water diversion boat just looked at the water line and couldn't help but mutter, "What exactly did you transport? Can you press the water line so low?"

When the ship entered the port and inspected the cargo, the customs personnel not only frowned. The extremely sticky black object emitted an unpleasant temperature, which was really unpleasant. It was heard that it was ‘asphalt’, and many people didn’t understand what was going on.

Soon, the technicians rushed to the port to pick up some samples. A few days later, in the city under construction, the original samples were used on the roof of the house. It was a dark brown thing, a few millimeters thick, and a little sticky. The engineers called it "oil felt".

The new-style houses in the city adopt a frame-like structure. Tiles were originally laid on the cement on the roof to block rain. Now all the tiles are removed. The large iron pot with a diameter of one meter is heated and asphalt is placed inside. The asphalt is completely melted after heating and then poured onto the roof. When the asphalt solidifies on the roof, lay oil felt and iron the oil felt smoothly with the heated iron guy.

While experimenting in the city, the commander of the large fleet negotiated the price with his old friend Feng Yukuan. After hearing the offer, Feng Yukuan sneered, "Haha, Oda, don't say that the price I gave is small. Our governor said that your asphalt was originally pouring out of the seaside, and no one wanted something. You collect, load and transport it on the seaside. We paid the freight, and it didn't make you work in vain. If you raise the price for me, you will transport the asphalt back."

The Spanish commander who gave himself a Japanese name, Oda Hideyoshi, saw that Feng Yukuan did not give in and whispered: "We will divide the extra ones."

"Don't you, mother's fart! You Spanish nobles are lawless in doing things. How can you compare to us in China? Are you going to kill me?" Feng Yukuan cursed angrily.

Seeing that Feng Yukuan did not give in, Oda Hideyoshi asked, "Will you still be there next time you are here?"

"We Governor said that if you bring asphalt, we will want it. But don't think about giving us a trick, just transporting it from Mexico. Don't think that we don't know anything. If you give me a flower job, I won't let you pass the level."

After being threatened by Feng Yukuan, Oda Hideyoshi didn't know how to answer, and finally he could only sigh: "Your Excellency Feng's loyalty is comparable to a believer's treatment of God. I want to ask you to see the Governor, and ask you to recommend it."

Feng Yukuan went to see Huo Chong, but unexpectedly Huo Chong was not here. Fortunately, the secretary helped and led Feng Yukuan to a construction site in Linzi. He saw Huo Chong and the head of the Construction Department of the Ministry of Works and others watching the roof laying. Feng Yukuan went up and saw that the oil felt had been laid on the roof and was brushing asphalt on the roof.

After rubbing his nose, Feng Yukuan felt that the smell was really bad. However, Huo Chong happily called Feng Yukuan over, "Brother Feng, after the roof of this house is washed, I am not worried about leaking."

"It's really not leaking?" Feng Yukuan was skeptical about this thing he had never seen before.

Huo Chong smiled and said, "Haha, it can last at least a few years. If the rain leaks in a few years, you can repair it with asphalt."

Feng Yukuan scratched his head, "That's the same as a tiles."

"It's different. Look at this roof, if you put a layer of prefabricated board on it, the roof can be fully used. If you put a tiles on it, do you dare to come up?" Huo Chong explained happily. Although the high-rise roofs in the 21st century rarely use oil felt, asphalt and other objects for waterproofing, when seeing oil felt again, I really feel like I'm closer to the 21st century. Even if it's just this feeling, Huo Chong is very satisfied.

Feng Yukuan was not interested, so he told Huo Chong the request from Spain, and finally said: "Brother Huo, why did the Spanish hurry to buy so many muskets? Did they hook up with someone?"

"You mean they had sex with the Qing Dynasty?" asked Lei Hu, who was looking at the new house next to him.

Huo Chong nodded, feeling that there was no such possibility. So he asked Feng Yukuan to negotiate with the Spaniards again, "If the musket is only used in the Europa area, we will sell it. But we have to rest assured, otherwise we will not be able to sell it."

Feng Yukuan went downstairs here, and Lei Hu looked back at the new houses and tentatively said: "Sir, can it be as dry as you said?"

"Is it dry? Everyone feels different. Comrades from Jiangnan must feel dry. I can be sure that the roof will dry very quickly, without water, and absorb water. If you don't live on the first floor, and you don't get dirt under your feet, it will definitely be dryer than before."

After hearing this, Lei Hu was very excited. But then he heard Huo Chong say, "But it's only a few months before you can move in. I'll take you to see these. Do you really think I just care about housing?"

"What does the governor mean?" Lei Hu felt all the doubts in his heart resolved.

"You go to Jiangning and start building a large grain warehouse in Jiangning's city to cope with the subsequent battles."

"What does a large grain depot have to do with fighting?" Lei Hu was puzzled.

"You have to eat grain when fighting. You have also seen grain warehouses, which are just open-air storage, which are easy to rot in Shandong, and are so humid and hot in Jiangnan. What do you think?"

Lei Hu talked with Huo Chong and the technicians for a day, then allocated supplies and transported a large amount of asphalt and materials for making oil felts and went south.

Feng Yukuan also found out the news and reported the results of the discussion to Huo Chong.

It turns out that France and Spain are both descendants of the "Borbon Dynasty".

Thirty-three years ago, in 1700, the death of Carlos II, the last male man in the Habsburg royal family, ended the rule of the Habsburg family over Spain for five generations. Carlos II's will was to pass the throne to his nephew, Philip, Duke of Anjou, the second son of King Louis XIV of the Bourbon royal family, rather than his Austrian cousin. Louis XIV's tough stance to defend the inheritance of his grandson, led to the outbreak of the Spanish War of Succession in 1702.

The war lasted until 1711, when the Bourbon royal family had gained a foothold in Spain and expressed their willingness to provide trade preferential and guarantees for merchants from Britain and the Netherlands, resulting in the collapse of the Habsburg coalition.

In 1714, Theo signed a peace treaty, and the Austrian Habsburg royal family recognized the Bourbon royal family as the leader of Spain, but Felipe V and his descendants had to give up the inheritance of the French throne. Since then, the Bourbon royal family of Western and French countries has officially separated.

Although the two families were separated, Bourbon was still the same Bourbon and the relatives were still close. The king of Poland was about to die, and European countries wanted the person they recommended to become the king of Poland. Moreover, there were conflicts between the countries of Europe. Of course, Spain hoped to win the next war with advanced weapons.

After talking about these things, Feng Yukuan felt that he had exhausted his energy and forced his understanding of some small countries on the distant European continent was really too unfounded. Feng Yukuan said with a buck: "Brother Huo, I have said everything I can remember, and it depends on you for the rest."

"Okay. Just tell them, I'll sell it."

Feng Yukuan was stunned, "Don't you see them?"

"It's okay to arrange a meeting and say a few words. But it's just some small European countries. You and I have already put in such a lot of effort, so there's no need to expect to say too much."

Here, the Spanish Hideyoshi Oda heard that he could buy weapons, and he was so happy. It was already very strange that the Chinese actually bought the asphalt flowing randomly by the sea. As Feng Yukuan said, asphalt is not valuable at all, and it is even easier to collect. If you can sell it, it is profitable. It is also a big profit.

The money for selling asphalt alone is almost enough to buy three thousand muskets and two hundred thousand bullets. As long as the Chinese are willing to buy such dirty and vile things, Oda Hideyoshi is equivalent to opening up a big deal that is sure to make a profit.

After meeting Huo Chong, the Spanish man Oda Hideyoshi quickly expressed his deep gratitude and requested that Huo Chong continue to sell medical anesthetics. After all, it is necessary to be injured in war, and surgery is required if he is injured. Chinese anesthetics are not only a shortage of gold and precious items in Europa, but also an extremely shortage of goods in Spanish colonies such as Mexico.

Huo Chong asked Oda Hideyoshi, "Second-hand muskets can be cheaper. Do you guys?"

When Oda Hideyoshi heard this, he asked for the price. He heard that the price of a second-hand musket was only half that of a brand new musket, so he was reluctant to let it go, so he nodded quickly to agree.

Soon, the waterline of the Spanish fleet surfaced. However, the fleet set sail. Since the asphalt he carried was sold out and the silver he carried was spent, it was useless to stay in China. After exhausting all his money, the ship was loaded with muskets, bullets, drugs, and silk. Although the weight was not large, it was a commodity that could make money when transported to Europe.

Thinking about the rewards that he would receive after returning to Spain, Oda Hideyoshi poured green absinthe into the captain's room and tasted the joys and sorrows. He looked forward to returning to Spain as soon as possible.

Just as the Spanish fleet left, Lei Hu's fleet had arrived in Jiangning. Just a few days before the start of the plum rain season, as long as the people who could invest in the city began to get busy.

Even so, there were also recruitment notices in Jiangning City. Over the past year, the people in Jiangning City have already understood that the Chinese army has strict military discipline and never bullies people. The transactions are fair and the employment is fair.

Since they were not afraid of the Chinese army's debt, many people went to work as short-term workers. He Kun wore short straw sandals and lined up behind the others. After arriving here, someone gave him a waist card. He Kun was assigned to Ding Group and entered the city with Ding Group.

When he returned to his former residence, He Kun found that he was not excited. Like him, there were several people lurking in Jiangning City after evacuating Mancheng. Those guys often missed the life in the city in private. He Kun from Zhengbai Banner did not miss him much. Compared with the days in the city, he felt that the gathering place of Han people was more interesting.

Walking in the city, He Kun remembered what he saw. Many roads in the city were widened, and the things that were in trouble in the past were removed.

Although he didn't know what the Chinese traitors wanted to do, He Kun just felt that it would be more convenient to rush on such a road after the court returned to Jiangning in the future.

Group D soon assigned a house, ladders were ladders, and everyone began to go up the roof and lift off the tiles.

The tiles are all placed on the rafters, so you have to be careful. He Kun couldn't help frowning, but he didn't know what mysterious things the Chinese thieves wanted to make. If it was to replace the tiles, it would be to take off one side of the roof. Unexpectedly, the Chinese thieves here actually took the beams as the middle part and removed the tiles symmetrically.

When the workers worked hard, some people wearing the Chinese thief army came up along the ladder. They nailed some wooden strips in the middle of the rafters, laid bamboo strips, and nailed them tightly with nails. Then they spread some long strips of disgusting smell on the bamboo strips, and nailed them tightly with nails again. Then they roasted these black things with fire.

The flames were everywhere, and the smell was stinking. The workers all covered their mouths and noses, and their faces were full of disgust.

After working for a while, He Kun had already seen some clues, as if these Chinese thieves were using bamboo strips and black things to reinforce the roof.

When it was open at noon, I ate and chatted with the workers assigned to Ding Group. Someone said, "That thing that I don't know what kind of film looks like is impermeable."

He Kun was stunned. He didn't look down on the Han people very much, but this Han people were just a small worker. Unexpectedly, he had already seen the changes that He Kun saw.

After working during the day, at night, the Chinese people lit the car lights and illuminated the streets. They had to work all night long.

For several days, the workers worked with several shifts of the Chinese army in the city. They had to renovate all the houses before the plum rain came. The sky was gloomy, the clouds were getting thicker and thicker, lower and lower. Standing on the roof to work, it seemed as if you could touch the clouds with your hands.

However, the rain never fell. It was not until the house was renovated and the tiles swelled to the roof again, and the fine raindrops fell from the sky.

The workers hurriedly hid in the checkout room. There was still a little strange and unpleasant smell in the air, but it was quickly dispelled by the rain. The workers looked up at the dark roof under the dark sky, not knowing what to say for a moment. Only the checkout voice came from each room.

After a while, someone suddenly asked in confusion: "Did you see that? It turns out that there is no leakage. It's really not!"

After saying this, He Kun felt a little unhappy. Unexpectedly, what he noticed was also noticed. No matter how the rain hit the tiles, the rain flowed down the tiles and fell into the yard along the eaves.

If you are outside the city, even the houses of wealthy families cannot be so leaky. Not to mention standing under the eaves outside the house. For ordinary houses, not only will they become water curtain caves under the eaves, but at least they will leak water everywhere.

Until he got the money, He Kun did not see any leaks in the area. Except for the water stains on the feet of people outside, no other places were wet.

Not only that, the sound of rain hitting the eaves in the past was very clear. Now the sound of rain is not loud, as if it was isolated from a thick layer of things, and only a dull sound came into the house, making the voices inside the house appear much clearer.

When he returned to his residence, He Kun immediately felt that he had returned to the normal world. The sound of rain slapping on the roof tiles was clearly audible, and some roofs that had not had time to repair began to drip down.

Although the air was humid, it was obvious that the houses that had been repaired in the city were dry and dry. He Kun couldn't help but feel sad, and he felt that the people were suffering endlessly. When he was sad, there was a knock on the door outside. When he opened the door, he saw that they were other brothers lurking in the city.

The brother slipped into the house in the rain and said happily: "The court sent someone to the court and said that he would be called back when the rain stopped!"
