……

The territory of a country needs to be exhausted and then drawn. At a time when transportation can only rely on horse-drawn carriages and boats, it is not an exaggeration to say that topographic maps are important weapons of the country.

It would be extremely difficult for a single person to accomplish this feat.

And they needed more than just a simple map. Nan Yu's troop deployment, environmental characteristics, how to deal with miasma, and many extremely dangerous Gu worm Gu techniques are all things that need to be understood.

The terrain is treacherous, surrounded by high mountains, and only a few places are passable.

In addition, the internal rivers are vertical and horizontal, and the Yangtze River, Minjiang River, Tuojiang River, Jialing River and other rivers flow through the entire Nanyu, which is extremely convenient for internal water and land transportation, but there are high mountains to block it externally, which is easy to defend and difficult to attack.

If there is really the danger of mountains and rivers outside, and the accumulation of heaven inside, it is impossible to encircle and consume it to death.

Listening to Zuo Zhangheng's eloquent talk, not to mention Xiang Xiong, even Yang Shili was wide-eyed.

"When have you been to Nanyu? How do you know so much? Yang Shili was so surprised that he almost pulled off his beard.

Zuo Zhangheng's face turned red, and he said a little uncomfortably: "Where has the son-in-law been, this is all Di'er's master told her as a travelogue, and she told the son-in-law again." ”

"Oh? How much skill does De Jong's second girl have? ”

Yang Shili was slightly surprised, and became a little complacent, no matter how powerful he was, it was his granddaughter, his species!

"The master of the second girl seems to be a stranger, otherwise he would not be able to teach such an eccentric girl." Yang Shili is half questioning and half affirming.

Zuo Zhangheng nodded, and was about to answer that he thought the same, but suddenly an unfamiliar voice came from the door:

"What use of her master, she is a stranger herself, you don't even know?"

Yang Shili's eyes flashed, and he shouted: "Who is the rat, dare to eavesdrop outside the old man's study, get in!" ”

When the words fell, he flicked his fingers, and a wisp of strong wind "swished"

I saw that a round hole appeared in the three-inch thick wooden door, Zuo Zhangheng's scalp was numb, and he was afraid that his father-in-law was about to become a sperm, and his internal strength was not reduced but improved a lot.

"Ding"

There was a crisp metal crash almost simultaneously outside the door, and at the same time, another voice sounded.

"Father, don't do it, it's a child."

Hearing the second voice, Yang Shili stopped moving, and Xiang Xiong stepped forward in two steps to open the door.

Outside the door stood a middle-aged man and a young man.

The middle-aged man is long, and his appearance is somewhat similar to Yang Shili, but he is not as fierce as him, and he has a little more culture. He is the brother of the Yang family, the son of Dingshan Gongshi, Yang Yangwen.

As for the young man......

The young man was dressed in a white shirt with a cold temperament, holding a steel bone fan in front of him, blocking his face.

The whole body of the steel bone fan is silvery, and you can see the extraordinary product at a glance, and a small piece is concave on one of the fan bones, which is very eye-catching.

"Dingshan Gong has a great ability, if it weren't for the fact that this bone was made of thousand-year-old cold iron, wouldn't he be going to die on the spot?"

The voice of the young man in the white shirt was as cold as his temperament, but his words were aggressive and not polite at all.

As he spoke, he took down the steel fan, waved his hand, and the fan "snapped" and closed.

Only then did Zuo Zhangheng see this person's face.

The man's long hair is jet black, which is in stark contrast to the white shirt, and his skin is porcelain white, which is even more delicate than that of a woman. The lips are thin and lightly pursed, not like an easy to approach. And the most eye-catching thing is his eyes.

His slender eyes are as cold as the stars, and he is good-looking, but his eyes are extremely cold, as if he has no human emotions.

Standing in the courtyard in the sun, this man was like a lone eagle standing on the top of a cliff, cold and arrogant but arrogant and domineering.

Yang Shili stood up, crossed Zuo Zhangheng, pushed Xiang Xiong next to the door, and squinted dangerously at the visitor: "The skills are good, and the fan is even better." You stand outside the old man's study and eavesdrop, do you think you should die? ”

The white-shirted young man ignored his question at all, but turned his head to look at Zuo Zhangheng, and asked as if no one was around: "You know the Yangtze River in the lower part of the world, but where did you know the names of Minjiang, Tuojiang, and Jialing River?" Why have I never heard of it? ”

Zuo Zhangheng was slightly stunned, he didn't expect this stranger to ask him a question, and he didn't react for a while.

Yang Shili's face was even more angry, and Yang Yangwen next to him saw that his father was about to go berserk, so he hurriedly played a round: "Father, don't worry, he is an envoy from the country and has received the emperor's order to visit you." ”

Seeing that Zuo Zhangheng didn't answer, the white-shirted young man swept over him with an indifferent gaze and fell on Yang Shili: "What envoys are so magnificent." It's just a spy and a meticulous work, you want to know the situation of the Southern Message, I am the Southern Advisor, and everyone takes what they need. ”

Yang Shili's gaze became playful, this person ...... It's kind of interesting.

"Now that you know the identity of the old man and the others, what about you? Who is it? ”

The white-shirted young man's voice was cold: "The southerners are leaving." ”

As soon as these words came out, everyone's eyes flickered.

There were no easy people present, there were military generals and civil officials, but no one had ever heard of the surname Nan or Nanren in the world, combined with his name......

"It's a reliable piece of work to hear the name."

Yang Shili once again showed a "smile" that was enough to scare the crying child: "The old man is looking forward to what news you will bring." ”

The southerners were noncommittal, and once again set their eyes on Zuo Zhangheng: "On the orders of your emperor, the topographic map of the Southern Decree can be presented below, and the method of dealing with miasma can also be presented." But under one condition that you"

He stretched out his hand and pointed at Zuo Zhangheng, his thin lips slightly opened: "The person who told you the names of those rivers needs to see them first." ”

Zuo Zhangheng's pupils shrank, he didn't answer this question, but said to himself: "You said that the old man and the second daughter are aliens themselves, what evidence do you have?" ”

From the time this person appeared to the present, he has been leading everyone by the nose in all kinds of answers.

When Zuo Zhangheng said this, he didn't expect him to answer honestly, but he didn't want to follow his rhythm anymore.

Unexpectedly, Nanren turned the corners of his mouth slightly for the first time: "I know Mo Chen below, I know Zuo Yan, what is so strange about knowing her identity?" ”

What the? Mo Chen? Left gradual?

Zuo Zhangheng's lips moved, and his eyes were a little moist for a moment. This man is one of them?

Since Mo Chen returned to his home six years ago and Zuo gradually left home, he could only get sporadic information about them from nearby channels, but he could not contact his eldest son and younger disciples.

He knew that the two of them must have a lot of ups and downs in the country, but he, a father and teacher, couldn't help at all. It's longing and guilt.

"Come, go into the study and talk, and tell the old man how the two of them are doing? Are you okay? ”

Yang Shili's old face fell, and he watched his son-in-law enthusiastically welcome people into the study, and it was too late to pick people up.

I had no choice but to blow my beard and glare at my son with a black face: "What do you see, your sister is more than two months pregnant, why don't you hurry back and make a villain, what are you doing here?" Do you want Lao Tzu to be the last to fail? ”

Yang Yangwen was speechless, he worked very hard, but only Yang Yucheng had a son, and he died early......

didn't dare to talk back to his father, he arched his hands and hurried away. It's really unlucky, but if you lead the way, you can get a scolding.
