Seeing off Yin Zhenhai and Lee Chengdao, Zheng Guanyin turned his head to see a desolate scene, except for a cement road and a few simple temporary houses, the port was nothing.

The location of the port is in modern-day San Francisco, where San Francisco is located. However, due to the problem of limited manpower, only the cement road from Yancheng to San Francisco was built, and even if the cement road was built, the distance between the two places was too far away, and it took a lot of time to take a horse-drawn carriage and a bicycle, so the port city was not developed. Now that there is a fixed source of manpower, it is impossible to say that this port city should be established.

Zheng Guanyin returned to the office building in Yancheng and asked Zhong Libo and Cao Chengji to be called to his office. The two of them had been busy for a while, Zhong Libo had to arrange and educate the newcomers - commonly known as brainwashing, Cao Chengji had to be responsible for the planting of tea trees and mulberry trees, making sure that they survived, and arranging for people to raise silkworms. Although Zheng Guanyin sent people to South America to find cotton, many of the nobles who followed her to the New World preferred silk woven from silk.

Now that the two of them have just taken a break, Zheng Guanyin is going to instruct them to work again. Fortunately, they have also cultivated several deputies in recent years, and they can issue orders and let the deputies do practical things.

Zheng Guanyin gave them two things: first, he was responsible for sending people to San Francisco to build the city and port; The next day, a railroad from Yancheng to San Francisco was built.

Cao Chengji asked, "What is a railway?" How should it be built? ”

Zheng Guanyin took out the drawings of the railway and handed them to Cao Chengji: "The railway is a special passage for trains to travel. After the railway is completed, Yancheng and San Francisco will be connected by train, and it will be possible to reach it in one day. ”

"What is a train?"

Zheng Guanyin smiled: "I will personally lead someone to make a train." ”

Before she could make the train, she had to get the steam engine out. Fortunately, in order to make a stronger sea vessel, she has made blast furnace steel, and now she does not have to worry about the raw materials for rails and steam engines.

and put Zheng Guanyin, who made the steam engine and the train, aside for the time being, and the camera turned to the side of Lee Seung-do. Lee Seung-dao and several younger brothers have been practicing the most basic movements of "broadcast gymnastics" with Zheng Guanyin, and their physical fitness is very good.

After almost two months, the sea ship finally docked at the coast mouth of Datang. Yin Zhenhai followed the instructions of the nautical chart and landed at the mouth of the Songjiang River. Once ashore, Yin Zhenhai sent people to collect supplies and recruit displaced people and ordinary poor people. Li Chengdao decided to separate from Yin Zhenhai, he wanted to go back to Chang'an to see, and the most important thing was that he wanted to go to his father's grave to put a stick of incense on his father.

Yoon Jin-hae felt that it was too dangerous and stopped Lee Seung-do.

Li Chengdao: "I am the son of man, since I have returned to the Tang Dynasty, how can I not sweep my father's tomb with incense?" There is also the fourth uncle, his family is not as lucky as us, so I can only sweep his grave and incense as a nephew. ”

Yin Zhenhai: "......"

As soon as these words came out, he couldn't stop them at all.

"But...... It's too dangerous. Yin Zhenhai said, "The last general will accompany His Highness together." ”

"No, you don't." Li Chengdao refused Yin Zhenhai, "When I set off, my mother gave me 'fairy drunk', and I will be fine." ”

Although Yin Zhenhai has not seen the power of "Immortal Drunk", he has heard others say that he knows that "Immortal Drunk" has killed several generals under Li Second. Since Li Chengdao has the "Immortal Drunk" in his hands, his safety can be ensured. Yoon Jin-hae let go of half of his worries, and the other half of his worries were also put down after Lee Seung-do put on his makeup to look unrecognizable.

"Your Highness, this makeup technique is amazing." Yin Zhenhai exclaimed.

"That's what my mother taught me." Lee Chengdao proudly said that his mother had no skills.

"Niangniang is really a pedantic genius." Yin Zhenhai admired Zheng Guanyin very much.

Lee Seung-do and Yoon Zhen-hae agreed on a return time and set off alone. Datang has also undergone obvious changes now, and the various products launched by the family have greatly changed Datang, although Datang is not as changing with each passing day as Yancheng, but the changes are also very huge.

Most places in Datang are paved with concrete roads, and bicycles and tricycles have become the most common means of transportation for most people. Li Chengdao found a shop selling bicycles, bought a bicycle, and rode to the capital Chang'an.

The distance from Songjiangkou to Chang'an is about 2,500 miles, if it is like Zheng Guanyin's speed of walking, it may not be possible to reach it in two or three months, but Li Chengdao has only one person, without any drag, riding a bicycle for six hours every day, only ten days of effort, Li Chengdao came to Chang'an.

Chang'an, where Li Chengdao grew up since he was a child, has changed a lot, and it is relatively small, depending on how people look at it. Li Chengdao approached the original Prince's Mansion, which had been diverted by Li Er for other purposes. The women of Li Jiancheng, who did not leave with Zheng Guanyin, had their own places to go, and sure enough, as they guessed, Li Er would not kill these women. Some of the women entered Li Er's harem, and some were rewarded to others. There is no Li Chengdao's mother-in-law here, his mother-in-law died when he was very young, and he was almost taken care of by Zheng Guanyin, so he has such deep feelings for Zheng Guanyin.

Li Chengdao walked around outside the former prince's mansion without attracting attention. He found a guest house to live in, and in the evening, Li Chengdao changed into dark clothes, quietly walked out of the guest house, and came to the former prince's mansion.

Accelerating and running ahead, kicking his feet on the wall, Li Chengdao easily jumped into the prince's mansion.

People often say that "things are not people", but unfortunately today's prince's mansion "people are not things", Li Chengdao can no longer find familiar scenery, the courtyard where he once lived was demolished and rebuilt, and the courtyard where Zheng Guanyin lives is also. It is said that there was a fire in the Prince's Mansion and many buildings were burned down.

Youyou sighed, and Li Chengdao left the prince's mansion disappointed.

The next day, Li Chengdao bought yellow paper incense wax to sweep Li Jiancheng's tomb. Li Yuan is still alive, and it is impossible for Li Er to let Li Jiancheng and Li Yuanji expose their bodies to the wilderness and simply collect and bury their bodies. Li Chengdao secretly inquired and learned about the place where Li Jiancheng's body was buried.

When I came to the tomb of Li Jiancheng, I saw a stone tablet erected in front of his tomb, and the stone tablet was engraved with an epitaph of 55 characters in Yangwen seal script: "The epitaph of the late Tang Dynasty Xiyin King Wang Zhen was built on June 4 of the ninth year of Wude, and on the 13th day of the first month of Wuzi in the first month of Wuzi, Xin Youshuo was buried in Gaoyangyuan of Chang'an County, Yongzhou. ”

When Li Chengdao saw this epitaph, his eyes turned red all of a sudden.
