"Lord, I wonder if the terrain on this map is different from the actual terrain now?" Lu Su raised his head and asked with expectation, his eyes shining.

"Wait a minute, is there something different? Let me take a look!"

Seeing Lu Su like this, Yang Song was startled. Hearing what he said seemed to be different, he quickly compared the terrain on the mini map.

Yang Song stepped forward and looked at the map carefully, and then compared it with the small map. Slowly, Yang Song also frowned and said.

"Hey~, why is this hillock gone? Why is this creek gone? This river has changed its course. What's going on?"

"Lord, if my subordinates are not mistaken, do these changes have one thing in common?" Lu Su became even more confident after hearing Yang Song's surprised words.

"What do they have in common?" Yang Song raised his head curiously and looked at Lu Su, waiting for his next words.

Lu Su didn't show off, and said directly: "Are these places with changed terrain connected into a line, as if they lead to one place?"

When Yang Song heard this, he also thought of something. He suppressed the excitement in his heart and looked at the map carefully.

really!

Starting from the hills in the north, to the depths of the mountains in the north, there are more or less changes in the terrain, and there are changes all the way to the unexplored junctions!

In the north of the territory, there are only industrial towns in the northwest, so it is no wonder that these terrain changes were not noticed.

Moreover, the earthquake a few days ago also frightened the people in the territory, making it even more impossible for them to go deep into the dangerous mountainous area at this time.

Therefore, no one discovered it until Lu Su came to find him.

As for why the dispatched cavalry has not reported back yet, I don't know.

Yang Song thought of this and said to the door: "Here comes someone!"

"My subordinates are here!" The guard outside the door came in and clasped his fists in anticipation of the order.

"Go and call Zhou Wu." Yang Song decided that instead of thinking too much, it would be better to call for someone and ask him to make it clear. "Ask him to bring the map of the north."

"I obey!" The guard took the order and went out to deliver the order.

"Lord, it seems that if you follow this line, you will definitely be able to find the passage." Seeing that Yang Song had proved his conjecture, Lu Su breathed a sigh of relief and was a little hesitant to say: "It's just..."

"What's the matter? If you have something to say, just say it!" Yang Song was very tired of this kind of behavior where he wanted to say something but didn't say it, and said half of his words.

"It's just that my subordinates are worried that this phenomenon is not limited to our territory." Lu Su saw Yang Song's expression and hurriedly said: "There may be such a line on the other side of the mountain range!"

Yang Song was shocked when he heard this. Lu Su's worries were not unfounded, and based on the characteristics of the system, it was only reasonable that such a situation would occur!

The most important thing is that it is completely unclear what kind of world is across the mountain range. If someone discovers the existence of the territory one step ahead, the territory will be in danger!

But it was not urgent enough for Yang Song to immediately issue an order for all personnel to prepare for war.

After three years, it has at least been proven that humans in this world do not have high technology, at least not airplanes!

There are no special powers. This is because there are no magical creatures that can breathe fire or electricity in the deep mountains and old forests. The most common ones are ordinary beasts, but the types and shapes are different from the previous ones.

Speaking of creatures, Yang Song has been in this world for three years and has not seen any large animals with six legs. He has seen a lot of molluscs without legs.

The varieties are similar to those before, including insects, mammals, cold-blooded ones... In the end, it’s all about appearance! (Um, I’m sorry, I feel so sad when I write this!)

"But lord, don't worry too much. We have such an accurate map and we didn't realize it until now. The people on the opposite side shouldn't be so fast!" Lu Su comforted.

"I hope so!" When Yang Song heard this, he felt a little relieved and said, "Even so, we must find the passage quickly so that we can feel at ease!"

"What the lord said is true!" Lu Su agreed.

If Lu Su hadn't known the importance of the passage, he wouldn't have run to Yang Song in such a hurry after discovering it!

"Subordinate Zhou Wu, please see the lord!" At this time, Zhou Wu came over and stood outside the door and said: "What important matter does the lord summon for your subordinates?"

Zhou Wu was in the military camp sorting out the situation reported below. After hearing the lord calling him, he took the map and prepared to leave the camp.

As soon as I walked to the door, I really thought about something. I turned around, picked up a few pieces of information and put them away, and took them to the lord's mansion to meet the lord.

"Come in." Yang Song waved his hand to let him in, and said: "What's going on these days? What's the reward for the cavalry who go out to investigate?"

Zhou Wu felt that there was something wrong with Yang Song's tone and did not dare to say anything else. He replied: "My subordinates have been sorting out information these days, and there has never been anything else. The latest reply from the cavalry who went out to investigate just arrived this morning!"

Zhou Wu took out several intelligence letters from his arms, handed them to Yang Song with both hands, and said: "Lord, please take a look!"

Yang Song took it with an expressionless face, opened it, and found that it was about a change in terrain somewhere. When he looked at the location carefully, he saw that a mountain in a mountainous area in the north had split into two halves. In his reply,

I asked if this was the passage I was looking for.

Yang Song checked the small map based on the location in the letter. After finding the location, he found that it was just a hill splitting to the left and right in the east-west direction.

"This letter arrived this morning, but what about the replies from the past few days? This place is already inside the mountainous area. Where are the replies about the changes in terrain outside?" Yang Song asked expressionlessly.

The place he wrote back to was far into the mountains. He believed that there must be more information about the changes in the terrain than the ones in front of him.

"Lord, please atone for your sins!" Upon hearing this, Zhou Wu was so frightened that he knelt down on one knee and said in fear: "My subordinates didn't know at first that the information about the terrain changes was so important to the lord, and they initially thought it was caused by the earthquake.

I didn’t take it to heart until I saw this reply today saying that a target similar to the passage was found, and my subordinates realized that they had made a big mistake!”

Although Yang Song knew that the cause of the earthquake was the passage, he forgot to tell others. At this time, after hearing Zhou Wu's explanation, he understood their thoughts.

"Hey, Zhou Wu is not a professional intelligence officer, so he can't tell that the relationship between the two is normal!" Yang Song thought to himself, so he said: "Get up!"

"I didn't say I should blame you. Remember to use your brain more if anything happens in the future!" Yang Song said gently: "Take out the map and I will draw a line for you. You can explore according to this line!"

"Remember, if anything happens, report it as soon as possible!" Yang Song instructed.

"I would like to thank my lord! I obey your orders!" Zhou Wu said gratefully.

Zhou Wu took out the map and put it on the long desk. The original map was put away by the cautious Lu Su when Zhou Wu came in.

Yang Song picked up the pen and drew a winding line on Zhou Wu's simplified version of the map (without information about mineral resources) based on the small map.
