Li Jing's signal tower, which is no more than every 40 miles, can just use a telescope to see specific signals. Sunny weather is signaled with a stand. At night and on cloudy days, the signal is indicated by using carbide lamps and red lampshades, and moving blinds.

Thanks to a large telescope with high magnification, the transmission speed is 300 kilometers per hour. Fifteen signal towers on this line from Jingshi to Dagukou have been completed. Information can be transmitted from the capital to Dagukou in less than an hour. A 600-kilometer route from Beijing to Yuanwei (Xingcheng and Huludao) and Zhongtunwei (Jinzhou) along the coastline to Yingkou is under construction. More than 30 signal towers on this line can deliver messages to Yingkou in just two hours. However, the section from Jinzhou to Yingkou is not safe and will be exposed to the attack of Jiannu.

This method of communication was invented by the French engineer Chape at the end of the 18th century based on the visual principle of Beacon Communication. He presided over the establishment of a communication system consisting of 16 signal towers for more than 230 kilometers between Paris and Lille. The signal is operated by the signalman on the lower side by means of a rope and pulley, and the different angles of the bracket represent different information. During a battle between France and Austria, it took only an hour for the signaling system to reach Paris. Later, Belgium, the Netherlands, Italy, Germany and Russia also established this kind of world system. Li Jing just copied it.

Dagukou and Qinhuangdao to Yingkou mainly rely on the newly built small clippers with a speed of 20 kilometers per hour, if Jinzhou is besieged and Ning Yuanwei is besieged during the war, they will take the sea route from Qinhuangdao.

Originally, according to the plan, an attached inn would be built, and Li Jing planned to directly build a miniature fortress castle-style inn. But this takes time, so we can only recruit people to build it slowly, and in order to catch up with the schedule, the signal tower is made of wood, that is, the logs are directly riveted with rivets. The inn and horse ring below are also riveted frames made of wood, the outer wall is nailed with clay and made of clay, and the dining place is built with a bamboo shed. It won't take a few years. Anyway, because of the ugliness, let's build this line first. It can be convenient for merchants to come and go, and it can also be used as its own logistics base. And don't expect to make money either.

When the news of the invasion of the Japanese invaded reached the capital, the whole city fell into a panic, and the Ming Dynasty had been peaceful for a long time, except for Tumubao and Yan Song, there had been no foreign enemies in the vicinity of the capital for a long time.

The emperor was no longer busy with his carpentry work, and summoned his ministers one after another to inquire about the situation. The cabinet is already preparing to transfer troops from Jizhen, Datong, and Baoding. The gates of the capital are also closed, as if facing a great enemy.

In the exchange, Lao Wu, who came to Beijing to preside over related things, looked at the cloth market that plummeted again, sighed, and explained when the son left, the price should not be higher than half of the normal cloth price, if it fell too much, use the fund to buy the disk, do not collapse. If it crashes and the exchange goes bankrupt, Childe's hard work will be in vain. If the price is more than half, the shipment will be suppressed.

The cloth in Li Sancai's hand fell by two-thirds, but it was still worth one million taels of silver, and if it was sold in time, plus the real estate of the family, it would almost be able to pay it back. But, apparently, the eunuchs did not give him this time. Soon after, he was imprisoned.

Li San was finished, and the three million military expenses did not know where to go, which alarmed the emperor. The result of the civil investigation was that Wang Zhizao, the head of the household department, and Chen Juren, the head of the military department, privately lent money to Li Sancai, but they were robbed by the Japanese robbers. As for the matter of raising the price of cloth, Li Sancai was sentenced to prison for the crime, confiscated the family property for compensation, and the Li family's 300,000 mu of land can be worth one million taels of silver, plus the shops, inns, and real estate in the capital and major cities along the canal, and some of the workshop shares invested in Suzhou, 800,000 taels can also be confiscated.

Although the emperor was angry, Li Sancai was so rich, and he didn't know that Li Jing had robbed tens of millions of taels of property and burned the debts. The civil servants collectively said that they were conclusive, and there was no way to continue the investigation. In the end, it didn't work.

As for the million pieces of cloth, their whereabouts are unknown. After Li Sancai and dozens of others were arrested and imprisoned by Jinyiwei, a group of mysterious people took over the Dongbalizhuang warehouse and transported the cloth. As for whether these cloths ended up in Mongolia or Jianzhou, no one knows.

On the front street, the newly bought three-story building of the main store of the bargain square was newly opened after a simple renovation, and Li Jing just painted the walls, paved the oak floor, and installed the calcium carbide lamp glass crystal chandelier on the ceiling. The inside of the openwork windows is fitted with flat glass. The first floor is a private room with scattered seats and a screen partition on the second floor, and a private private room with solid wall masonry on the third floor.

The largest private room on the third floor has a large rotating table for 20 people. I bought some calligraphy and paintings of celebrities, put them in glass and mahogany frames, and hung them on the wall. The atmosphere looks simple, bright, clean and atmospheric.

Three kinds of roast duck and whole duck feast were an instant hit in the capital. In addition, the small window on the street sells duck liver, duck gizzard, salted duck eggs, Songhua eggs, spicy duck neck, etc. From the beginning of the opening, there was a surge of people. It's not okay to envy and hate other restaurants, but Zhu Shou's relationship in Beijing is still very good, and everyone knows that this store has a deep background, and no one dares to find fault.

On the second floor, near the window, a group of diners were discussing.

"Brother Chen, have you heard, the Japanese are back again."

"I just heard that Tianjin has fallen, and the flames are soaring,"

"Yes, I arrived in Zhangjiawan yesterday and robbed Lord Li Sancai's mansion. It is said that it is opening up the state. ”

"Yes, this Tongzhou can't be guarded, after Tongzhou, you will reach Chaoyangmen. There are two Zhuangzi outside the Chaoyang Gate in my house, which are going to be poisoned. ”

"I don't know, I went to walk the birds this morning, guess what, I saw the British Duke with the general out of Yongdingmen, and the streets of Qianmen were under martial law, and it took half an hour to remove them."

"So the three battalions are going to send troops."

"It seems that the British duke personally went out to fight, which shows that the Japanese are powerful."

Outside the Donghua Gate, Zhu Shou, Li Weier, and Li Yueer were chatting and drinking coffee. Everyone left, looking deserted, just when Zhu Shou came over and was chatting happily.

"Have you heard, the Japanese invaders have made a comeback, and they have broken through Tanggu and the military grain city, and it just so happens that my brother has gone for three days, otherwise he happened to collide with the Japanese invaders, so dangerous." Zhu Shou had a palpitating expression.

"Hehe, what's so great about the Wako, it's not like I haven't seen it." Li Yue'er said nonchalantly.

"You've seen the Japanese Kou, didn't you say that they are all devils who kill people when they see them," Zhu Shou said in surprise.

"The Japanese people are in awe of the strong, as long as you are stronger than him, he will obey you very much, and the Japanese are all the people of the Ming Dynasty, and there are not many real Japanese people."

"What, there are not many Japanese people, most of them are the people of the Ming Dynasty. How do you know," Zhu Shou said in surprise.
