After chatting with mother and son, Cheng Qian walked all the way to the study, thinking about A-Niang's thoughtfulness and concern, he couldn't help but feel a lot more comfortable, and the inferiority complex caused by Dai Wenxi's arrogance had almost dissipated. Looking at Li Shimin's face again, he didn't feel embarrassed. He understood that the father needed an explanation for his trip. Although there is a bit of questioning, if you think about it carefully, it is not a father's love and worry for his son.

"Cheng Qian has seen Grandpa." Li Chengqian was confident, looked at Li Shimin with a straight face, and stepped forward to salute unhurriedly.

"Alright, sit down and talk." Li Shimin's tone was soft, and Li Chengqian's heart was even more relaxed, as long as it was not an interrogation.

"Go out this time, just come back safely, you have experienced it yourself, the state affairs are difficult, the people's hearts are sinister, don't be reckless in the future. Unless you have the ability to deal with all kinds of changes. ”

"What Grandpa said is that you must be cautious in the future." Li Chengqian paused for a moment, and then said, "Although I encountered some trouble on this trip, the harvest was much greater than in the capital. The biggest gain is to know that there are people outside the world, there is a sky outside the sky, and there is a larger area outside the Tang Dynasty. And there are many strange people, if they can be used by my Tang Dynasty, the country will be strong and prosperous, just around the corner. ”

"At a young age, you must learn to be cautious in your words and deeds, and not to be arrogant. It seems that your heart is wild, let's talk about it specifically, if you can really say a Tao, I won't punish you this time. Li Shimin was a little funny in his heart, and this was out of efficiency.

"Naturally, I don't dare to be arrogant, but the harvest is not small, Grandpa, please see, this is the biggest harvest of this time, the map I collected." Li Chengqian hurriedly took out the world map from his arms and carefully handed it to Li Shimin. This was made in Qingfeng Village after being re-modified by Dai Wenxi.

At that time, I was nominally asking for advice, but in fact, I wanted to show off with that psychopath, and I wanted to regain some sense of superiority and existence. As a result, he continued to be slapped in the face, this kid knew more knowledge than himself, which made Li Chengqian feel very lost for a while. The map he took out at the moment had been processed by him, mainly old, and it seemed to have a mysterious and vicissitudes of life, like an ancient sheepskin scroll.

"It can't be that someone cheated on you." Li Shimin smiled disdainfully and reached out to take the scroll. He knows better than anyone that the map is a top-secret thing in this era, whether it is the territory of the Tang Dynasty or the maps of other countries, it is difficult to find traces on the market. A child can get a map, isn't this a scam?

Gently unfolding the map, Li Shimin only glanced at it slightly, and could no longer take his eyes off. Li Chengqian took the opportunity to come forward, pointed to the map, and said to Li Shimin: "Grandpa, please see, the Turkic (east) is in the north of the Tang Dynasty, in the north of the Turkic (east) is Xue Yantuo, in the northwest is the Uighurs, in the northeast is the Murowei, in the east of the Murowei is the Yao, in the north of the Murowei and the Ya is the driving Dumei, in the north of the driving Dumei is the Yaksha, and in the southeast of the Yaksha is the Liugui. The northern part of Youju and the southern part of Murowei are Xi and Khitan, the eastern part of the Khitan and the southern part of Yeoji are Buyeo (Goguryeo), the southern part of Goju (pronunciation: Goo) Li is Baekje and Silla, and the eastern part of Silla is across the sea is the Wa Kingdom. The Wa Kingdom and the Wandering Ghost face each other across the sea from the north to the south, and further east they are the Eastern Ocean. ”

With Li Chengqian's fingers and narration, Li Shimin slowly stood up, but his eyes did not leave the map, and he muttered incoherently: "Let me see, where is Chang'an?" Where is Youzhou? Where is Jinyang? What about Liangzhou? Why is Datang so small. ”

Li Chengqian was a little disdainful in his heart, and dared to love what I just said in vain. Is this untenable? But he said: "Chang'an is here, Youzhou is here, Liangzhou is here, the southwest of Liangzhou is Tuguhun, the west of Tuyuhun is Gaochang, Yanqi, Guizi and other small countries, the south of Tuyuhun is Tubo, the west and north of Gaochang are the Western Turks, and the West Turks to the west have Tocharo, Persia, and Dashi. To the south of Tibet and Tocharo are small countries such as Bolu, and further south you will reach Tianzhu. ”

"Is there the sea to the south?" Li Shimin finally understood the logo and direction of the map. Following Li Chengqian's guidance, he looked down the map.

"To the south of Jiaozhou is Luozhou, and the southernmost is Luofu Prefecture, and Luofu Prefecture used to be Linyi, and early indica rice was found here. To the west of Linyi is Lu Zhenla, the country of Bi, and the kingdom of the queen. In the middle of these small countries and Yaozhou and Lizhou is the six departments of Nanzhao. The Queen's Kingdom goes west to Tianzhu. Repeating the content of the map that Dai Wenxi told him, Li Chengqian was also helpless in his heart, he didn't know the surroundings of Datang at first, and under Dai Wenxi's contemptuous gaze, he asked for advice for a long time before he figured it out.

Today's Datang is actually very small, the Liang division is still surviving, and even small tribes like Khitan and Xi are eyeing the border.

"The southeast goes to the sea, that is, the Ryukyus, all the way south, you can reach the Boni country and many islands in the South China Sea, the area is not small, and further south, it is an uncivilized land, and the area is much larger than today's Datang. Beyond that is the Southern Ocean. The land with a large basic area is located in the west and north, of which the western Persia and Dashi are about the same area as the Tang Dynasty. To the west of the Great Eclipse was the Byzantine Empire, further west was Great Bulgaria, and a number of smaller kingdoms. All the way to the Western Ocean. ”

Li Shimin pointed to the continent southwest of Tianzhu and said, "This place is so wide, it's a good place. ”

"This is the homeland of Kunlun Nu, occupied by Persia, the Great Eclipse and Byzantium." Looking at the area as large as Persia and Dashi, as well as the area of Great Bulgaria, as well as the huge area in the north that spans east and west, Li Shimin gestured twice, silent, and Li Chengqian no longer spoke.

Obviously, Li Shimin was hit, and the scene was a little dull for a while, Li Shimin quickly sobered up and said: "How much is the distance to the Western Ocean, and how much is the landscape?" Do you think this thing is reliable? ”

Li Chengqian couldn't figure out Li Shimin's thoughts for a while, so he had to speak: "According to the measurement and accounting on the map, this trip to the western ocean is less than 20,000 miles, and if you add the mountains and rivers to block and bypass, I am afraid that it will be 30,000 or 40,000 miles away." As for the authenticity, I used to have doubts, but later I dispelled my doubts, have you ever heard of Zhang Zhongjian, the brother of Li Jing, the secretary of the Ministry of War? ”

When Li Shimin heard this, his eyes suddenly widened, and after a while, he seemed to feel that something was wrong, then sat down, stopped talking, and after a while, he said slowly: "I believe it, no wonder you said that there are immortal mountains, gold and silver overseas, it seems to be true." However, this matter must be considered in the long run, and whoever owns this map can be decided. Cheng Qian, you have made a great contribution when you go out this time. I will reward you well. Say, what do you want. ”
