"What's wrong?"

Xia Yu was a little confused. The place where Huo Qubing's spear pointed was also ordinary burnt black soil.

"Lord, look again!"

After saying that, Huo Qubing gathered his strength and struck hard, stabbing where the gun pointed.

Then the gun tip was picked up, tearing open a large piece of scorched earth.

The conditions beneath the scorched earth were revealed.

It is a circular passage with a diameter of one meter and a bottomless depth.

Filled with black and purple mist.

"this!"

Xia Yu was a little shocked. This place had been bombarded by the Meteor Battery.

Let alone the depression went down a hundred meters.

And even so.

This passage still exists, and there is no end to it.

Xia Yu's expression became a little serious and said:

"This problem cannot be taken lightly. We must find ways to find out the source!"

Huo Qubing and Temujin also looked solemn.

It can make a large magic cave appear out of thin air and upgrade quickly.

It must have something to do with this passage.

After all, black mist has always been one of the symbols of monsters.

If you don't find out clearly, the events behind this channel.

This will add countless troubles to the Chinese collar.

After all, the cost of using meteorite thunder cannons is still too high.

It's impossible to push it out every day and fire a cannon when you find a demon cave.

Not to mention that Xia Yu's wallet couldn't bear it.

Instead, they shoot guns near the territory every day.

There was no grass growing around the territory and there were lots of holes.

It's a waste of time, so pack up your things as soon as possible and prepare to move to the city.

"No, no, there is still a large area of ​​blood-drinking ore waiting for me to mine."

Put the thought of retreat out of your mind, return to reality and find a solution.

"But there are no items or generals that can be tracked."

Xia Yu has a headache. Huaxia Ling still has insufficient equipment and insufficient talents at this time.

I am racially marked and marked by others every day.

Now I can't even trace the source of a channel.

He said this, but if other lords saw Xia Yu standing next to two six-star golden generals, Temujin and Huo Qubing.

The soldier on the side also pushed a golden weapon.

He will definitely scold Xia Yu for being so lucky and unaware of his blessings!

When Xia Yu had a headache.

Temujin, who had carefully observed the passage for a long time, said:

"Lord, let me try."

"Oh? The captain has something to do?"

Xia Yu was a little strange.

No one knows Temujin's skills better than him.

But none of them are skills used for reconnaissance and tracking.

"Lord, wait a moment, I'm just experimenting."

After saying that, Temujin took out the bow from his back and nocked the arrow.

It stretched into a full moon and shot out towards the center of the passage with a "swish".

"What is this?"

Xia Yu was a little confused about this archery exploration.

It is completely unfeasible for underground passages.

It is not an underground passage built by humans, it is also paved with bricks and mud.

Although he didn't understand, Xia Yu still looked at Temujin and listened to the movement in the passage.

"This passage should go down about 300 meters."

"How to determine this? If the inside of the passage is full of potholes and the arrow turns to the potholes, won't it stop?"

Xia Yu asked his own question.

Facing Xia Yu's question, Temujin smiled slightly and said:

"Lord, please observe this passage carefully."

"Wherever you can see it, the cuts are neat."

"I just used the rolling stone to naturally roll down the channel wall."

"Then through the sound fluctuations when the stones roll, we can explore the unevenness of the invisible passage behind."

"And the sound I heard was relatively uniform, so I can confirm that although this passage is not absolutely straight, it is not full of potholes either."

"Finally, I will shoot an arrow through its middle."

"First, I have a better understanding of the speed of my arrow rain. Secondly, I can avoid the influence of the channel wall from the middle and better calculate the length of the channel."

"I see."

After hearing Temujin's explanation, Xia Yu suddenly became enlightened.

This is what military commanders are for!

Rich combat experience and strong adaptability.

Otherwise, how could he, a stupid young man who grew up on campus every day, manage such a huge territory well?

Everything depends on the help of the generals.

Seeing Xia Yu's reaction, Temujin smiled slightly and said:

"Moreover, when marching and fighting, the key is to be adaptable to changes. For such values, we only require a rough idea and keep it in mind."

"What it does is remind us that this move is here."

"Everything cannot begin until everything is fully prepared, especially for war."

After listening to Temujin's words, Xia Yu was silent for a moment.

He solemnly saluted him and said:

"You've learned a lesson, captain."

He also noticed that Temujin, who was usually taciturn, always preached to him a lot every time he marched and fought.

It was to teach him more things on the battlefield.

to achieve faster growth.

Not only him, but also Sima Yi when dealing with internal affairs.

He will also use many events to guide him and make the right decision.

Temujin saluted back and said:

"No need to be polite, Lord, this is also my duty."

Xia Yu showed a smile.

But before Xia Yu could finish comprehending what Temujin just said.

Temujin suddenly made a strange smile on his lips and said:

"Lord, that was the way to become a talent, now I'm going to teach you the way to become a general!"

After saying that, Temujin shook his hand fiercely.

He actually pulled out the arrow he had just shot from the passage.
