"What's wrong?"

Xia Yu was a little confused. The point where Huo Qubing's spear pointed was also ordinary charred mud.

"Lord, look again!"

After saying that, Huo Qubing charged a power and stabbed hard at the point where the gun pointed.

Then he picked up the gun and tore open a large area of ​​scorched earth.

The situation under the scorched earth was exposed.

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, and this place was bombarded by the Meteorite Fort.

It has been sank for less than a hundred meters.

And even so.

This channel still exists and cannot be found.

Xia Yu's expression became a little serious:

"This issue should not be underestimated. We must find a way to find out the source!"

Huo Qubing and Temujin also looked solemn.

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

It must be related to this channel.

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

If you do not investigate clearly, the events behind this channel.

It will add countless troubles to the Chinese leader.

After all, the cost of using the Meteorite Thunder Cannon is still too high.

It is impossible to launch it every day, and fire a shot when you find a demon cave.

Let’s not talk about Xia Yu’s wallet being unbearable.

Instead, they shoot artillery near the territory every day.

It made no grass grow around the territory and bumpy.

It’s a big deal. Get your stuff 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."

If you throw the idea of ​​retreat out of your mind, you should return to reality and find a solution.

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

Xia Yu had a headache. Huaxia still had poor equipment and insufficient talents at this time.

I am marked and imprinted by others every day.

Now I can’t handle it if I want to track the source of a channel.

He said that, but if other lords saw two six-star golden generals standing beside Xia Yu.

The soldiers on the side were also pushing a killing weapon of golden items.

I will definitely curse Xia Yu because he is in a blessing and does not know how to be blessed!

When Xia Yu was having a headache.

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

"Lord, let me try it."

"Oh? The captain has a way?"

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, I'll just experiment."

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

Pulling into a full moon, it shot out toward the center of the passage.

"What's the solution?"

Xia Yu was a little confused and was exploring this archery.

It is completely unfeasible for underground passages.

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

Although he didn't understand, Xia Yu still watched Temujin listen to the movements in the channel.

"This passage should have to go down about 300 meters."

"How to determine this? If the inside of the passage is bumpy and the arrow turns to the bumpy place, will it stop?"

Xia Yu asked his own question.

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

"Lord, observe this passage carefully."

"There is a neat part where you can see it."

"I just rolled down the passage wall naturally with a rolling stone."

"Then the sound fluctuations when the stones roll, we can detect the concave and convexity of the invisible channel behind."

"And the sound I heard was relatively uniform, so I can be sure that although this passage is not absolutely straight, it is not as bumpy."

"In the end, I shoot the arrow from the middle."

"First, I know a lot about the speed of my arrow rain, and secondly, from the middle, I can avoid the influence of the channel wall more and better calculate the channel length."

"I see."

When Xia Yu heard Temujin's explanation, he suddenly became enlightened.

This is the purpose of military generals!

Rich combat experience and strong adaptability.

Otherwise, for him, a young man who grows up on campus every day, how could he manage a huge territory well?

Everything depends on the help of the generals.

The reaction of Xia Yu on the opposite side, Temujin smiled slightly and said:

"And the key to marching and fighting is to adapt to changes. For such values, you only need to have a rough idea and grasp them in your heart."

"Its purpose is to remind us that there is this move here."

"It is impossible to wait until preparations are complete before war begins."

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

He politely said to him:

"I've been taught, lieutenant."

He also saw that Temujin, who was usually taciturn, had many preachings to him every time he marched and fought.

It is to teach him more about the battlefield.

To achieve faster growth.

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

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

Temujin replied:

"Lord, you're welcome, this is my duty."

Xia Yu smiled.

And before Xia Yu could finish understanding Temujin's words just now.

Temujin suddenly smiled strangely and said:

"Lord, that was the way to hide talent just now. Now I will teach you how to be a general!"

After saying that, Temujin swung his hand violently.

The arrow that had just been shot out was actually pulled out from the passage.
