Even Long Xiaohua knew this. Whenever the little girl had the chance, she would rub her brother to ask for this and that, and she would pull him to play and run wildly all day long.

At the same time, Shen Mo himself also took a laissez-faire or even doting attitude towards An Jun.

After a while, although An Jun has not yet become the silly and sweet sunny boy of later generations.

But now when he communicates with people, it no longer seems so strange.

Even after he showed off his naughty side of his temperament, he seemed a little naughty and nonsense.

However, Shen Mo was happy to see this because he knew that a person had a healthy mind, which was more important than how much he learned or how many skills he had.

...Now An Jun holds the package in his hand and quickly finds the Second Battalion Deputy Lu Zi'an.

After that, he opened the package in front of everyone in the tent in the second cabin office.

When this thing was revealed to everyone, everyone looked at each other and couldn't figure out what it was.

If you have to describe it, you can only say that he is a Coke can that has been magnified ten times.

Of course there was no such thing in that era, so everyone should think it was very similar to a high-waisted water bucket made of metal. But if you look closely, you will find that there are grids on it, which actually seem to be spliced ​​with countless metal blocks.

An Jun smiled and patted the weird guy, saying to the second battalion commander Lu Zi'an: "According to your requirements, I can make this thing. You can try the test tube on the battlefield and it doesn't work."

Judging from the appearance of this second battalion commander Lu Zian, he is clearly a gentle scholar as gentle as jade.

Even a straight military uniform could not cover up his bookish spirit.

However, since he can become the battalion commander, he is obviously very good at combat and command.

He frowned and blinked his eyes and looked at the thing for a while.

Then he asked An Jun: "It turned out to be the last incident, so how should I use it?

Lift it up and smash it at the Jin army?"

"Then I might as well give you a millstone," An Jun heard Lu Zi'an's words at this time, and immediately shook his head and smiled.

Then he took out a pencil from his shirt and pocket, found a piece of paper on the second battalion commander's table, and started painting it.

Within a few seconds, An Jun presented the sectional view of a tunnel to everyone clearly and accurately.

...It turns out that the cause of this incident was that when Lu Zian returned to the command center and reported the defense situation to Commander-in-Chief Li Muyuan, he said that he had encountered a problem.

The tunnel system located outside the city has been slowly discovered by the Jin army.

In fact, this tunnel cannot be hidden from anyone, because the Tongzhou army's elusive appearance and disappearance will inevitably remind the Jin army of the underground passage.

Therefore, when the Tongzhou army repeatedly fought with the Jin army for the ruins, they tried their best to cover up the entrance of the tunnel with broken bricks and tiles.

However, in the ruins that fell into the enemy's hands, the tunnel was still found by the Jin army one by one.

After this, of course, the Jin army also took corresponding measures.

They had tried to send people into the tunnel to attack several times, trying to follow the clues and touch the back of the Tongzhou military defense line.

After the tunnel counterattack failed and instead suffered losses, they also cut off the idea of ​​using the tunnel to attack the Tongzhou army.

Instead, he changed his trick and tried every means to use these tunnels to cause damage to the Tongzhou army.

This is the case in these days. After the cunning Jin army discovered an authentic tunnel, they did not make any statement.

Then they used the tunnel entrance to successfully attack the Tongzhou army that had penetrated the tunnel! As soon as nearly fifty soldiers drilled out of the tunnel, they found themselves in ambush.

That time alone, the Huaiyang Army lost nearly fifty soldiers.

Immediately, the new situation was discovered by the Huaiyang Army. When Li Muyuan heard Lu Zi'an's report, he immediately stopped using the tunnel to drill into the enemy-occupied area to avoid causing greater losses.

However, this made the Huaiyang Army go deep into the enemy's backbone along the tunnel and support the ground attacking troops' actions, and it was no longer effective! The Huaiyang Army now knew clearly that the outside of the tunnel that was discovered must be full of ambushed Jin troops.

Now when the Huaiyang Army launched a ground counterattack, it was becoming increasingly difficult to recapture the ruins due to the lack of authentic support.

However, when the deputy battalion commander Lu Zi'an reported to Li Muyuan, An Jun next to him happened to be heard by him.

After that, he promised Lu Zian to think of a solution for him, and within two days, he brought this thing to the deputy battalion commander of the sect.

...Then, An Jun compared the authentic sectional view and explained the purpose of this strange thing to Lu Zi'an carefully.

turn out to be.

This thing is a mother-child bomb handmade by An Jun.

The entire bomb is about one foot and three inches in diameter and two feet long, and it is a rectangular cylindrical shape.

In fact, it is made up of ninety small bombs, like the grid on a pineapple, embedded together in a tightly stitched manner.

Every small bomb was filled with iron sand seized from the Jin army.

The charge inside is the most commonly used extreme compressed gunpowder block in the Huaiyang Army grenade.

At the very center of this cob is a cylindrical bomb.

So after this thing is detonated, it will blow ninety killing bombs to the distance, and then all the small bombs will explode a rain of iron sand! According to An Jun, within the explosion range of this mother-sub-blast bomb, a large circle with a diameter of about 30 meters is all within its killing range. The Jin army in it will definitely not be spared, and each one is guaranteed to be injured.

So this guy's power and lethality are amazing.

As for how it is used... An Jun immediately pointed at this thing and told Deputy Battalion Commander Lu Zi'an what he thought.

...First, lay pipes at the exit of the tunnel, and rely on listening methods to determine whether there are any ambushes from the Jin army outside.

The ambush of hundreds of people will definitely make sounds of walking and whispering, which can be clearly identified through a simple listening system.

After this, as long as the Jin army is ambushing outside the tunnel entrance, Deputy Battalion Commander Lu can send someone to take the bomb and throw it outside the tunnel entrance.

Then a large number of Jin troops who were ambushing outside would be immediately covered by the exploded mother bullets. This big guy should be able to kill one or two hundred of them in one go.

...After An Jun's explanation, the battalion commander Lu quickly understood his intention.

But looking at his appearance, he still had some doubts.

"What if the other party throws him back from the hole while it doesn't explode?"
