"Sir, don't worry, I don't take this person lightly. My master, I think that the longer you stay in the city, the more dangerous your situation will be."

"Of course what the housekeeper said makes sense, but I thought that since the enemy started stalking, they must have a complete plan. If they left Jingyu County rashly at this time, they might have already set up a dragnet outside, so

Wait until we get in."

…

Ma Xiao's voice and Lao Niu's voice intertwined in Liu Heng's mind.

In the silent carriage, Liu Heng's fingers tapped on the table rhythmically, 'dong, dong, dong, dong, dong, dong...', becoming the only sound.

The sound stopped, and the carriage was so silent that there was no sound at all.

Liu Heng looked at everyone seriously and said slowly: "Both the views of Lao Ma and the housekeeper are reasonable, but I thought about it carefully."

Liu Heng paused and then asked: "Which one of you has a map here?"

Everyone looked at each other, hoping someone else would have a map.

When Liu Heng saw the silent crowd, he knew in his heart that they did not have a map around Jingyu County, and sighed secretly. He said in his heart: It seems that my idea has gone bankrupt before it can be implemented because there is no surrounding map.

.

Just when Liu Heng had extinguished his thoughts, Xiao Yu quietly raised his hand and asked weakly: "Sir, there is no map recording the surrounding terrain. Is there a map of Dai Viet that can be used?"

Liu Heng's eyes lit up when he heard Xiao Yu's question, and he replied eagerly: "Of course. Although the latter's records are not detailed, at least there is a reference."

Liu Heng then said: "Quick, quick, take it out."

Xiao Yu replied in a soft voice: "The map is not on me, it's in the carriage."

Liu Heng said: "Then you go get it, pay attention to safety, go and come back quickly."

Xiao Yu replied: "Here." Then he limped out of the car quickly and limped quickly towards another carriage.

Silence returned to the car, except for the sound of 'dong, dong, dong, dong, dong, dong...' tapping on the table.

After a while, Xiao Yu came back with a map in his hand and said: "Sir, this is the map of Dai Viet. Take a look."

Liu Heng took the map, spread it on the table, looked at the mountains and rivers painted on it, pondered for a moment, and asked a little awkwardly: "Um... do you know how to read this map?"

Everyone:......

Liu Heng died on the spot, and the scene was embarrassing.

Gao Qing took the lead to break the awkward atmosphere and explained: "Sir, look, this is the location of Jingyu County where we are." He pointed to the northeast corner of the map with his finger as he spoke.

Liu Heng looked at where Gao Qing was pointing, nodded, and asked, "Then what are those messy thick lines next to it?"

Gao Qing pointed to the thick line that looked like a triangle, and explained: "Sir, these are the mountains and rivers around Jingyu County."

Then, he pointed to the wavy lines invisible to the naked eye and said: "Sir, you see this is the river around Jingyu County."

Liu Heng nodded thoughtfully and replied: "I seem to understand a little bit."

Then, he asked: "Then how do you measure this distance?"

Gao Qing asked in confusion: "What distance, Master? I don't quite understand what you mean."

Liu Heng explained: "For example, how many miles does it take to walk from this mountain to that river?" Liu Heng slid his finger on the map from the mountain peak in the east to the river in the west, matching the questions he asked.

Gao Qing had never thought about this kind of problem. He looked at it for a while, thought for a while, and replied: "This depends on the experience and judgment of the person leading the army. The subordinates really don't know how many miles they need to walk."

Liu Heng listened to Gao Qing's explanation and looked at his dancing gestures. He was already dumbfounded. He couldn't imagine that Dai Viet's map was so low. It didn't even have the most basic quantitative standards. Everything relied on the freedom of the generals.

He sighed dully: "wc, with such a map, Dai Viet has been able to win so many battles over the years. How rubbish other ethnic groups must be."

"Garbage?" Gao Qing didn't quite understand what Liu Heng meant, so he asked, "Sir, I'm stupid and don't quite understand what you mean."

Liu Heng replied hurriedly: "It's okay, you don't need to understand."

He changed the subject and asked: "Is this a civilian map, Gao Qing?"

Gao Qing replied: "Yes, Sir, this is used by the people."

He asked again: "Are the military maps more detailed than this?"

Gao Qing took it for granted and replied confidently: "Of course, Master. The map used by the army is a hundred times more detailed than this map."

Liu Heng's eyes lit up again, and he secretly affirmed in his heart: If the map used by the army is very precise, Vietnam can bully countries of other ethnic groups, so it makes sense.

Gao Qing didn't notice Liu Heng's soliloquy in his mind, but continued to introduce the army map and said: "Sir, look, this mountain doesn't look like a mountain at all.

The mountains are all about the same size. Looking at this map, who can tell whether it is a small mountain or a big mountain..."

Liu Heng came back to his senses and asked puzzledly: "How can we distinguish between big mountains and small mountains on the army map?"

Gao Qing glanced at Liu Heng with disdain, but then he thought something was wrong and quickly lowered his head and replied: "Sir, of course the mountains should be painted bigger, and the hills should be painted smaller."

Liu Heng:……

Sure enough, ancient people really didn’t have quantitative thinking. Which painting should be bigger, which hill should be smaller, and how much smaller? And why is this guy so smug and proud? Forgive me for being poorly educated and uneducated.

I can't understand it.

Liu Heng looked at Gao Qing with caring eyes and said: "Ah Qing, are you thirsty after talking so much? Take a drink of water quickly to moisten your throat."

Gao Qing replied: "Master, I am not thirsty. I will continue to serve you..."

Liu Heng interrupted his eloquence and said forcefully: "No, you are thirsty. I think you should drink water to moisten your throat."

Gao Qing looked at Liu Heng blankly, and could only say helplessly: "Thank you, Mr. Master, for your concern."

Liu Heng felt relieved when he finally interrupted Gao Qing. Then he focused his attention on the map and asked, "Does any of you know where there is terrain near Jingyu County that is easy to defend but difficult to attack?"

Everyone looked at Gao Qing who was drinking water. After all, he was a professional.
