On the other hand, my younger brother could see the problem in just a few seconds.

For a moment... Gu Qingwan felt a little bit...

Have you really delayed your brother...

As for Lu Yuan's current appearance, Gu Qingwan could naturally see that this Lu Yuan definitely had a solution to these problems!

Seeing Lu Yuan like this, Gu Qingwan pouted, then patted Lu Yuan on the shoulder and said:

"Okay, you must have a way, tell me quickly."

Afterwards, Lu Yuan shook his head and looked at Gu Lie with some pride and said:

"Do you think there is a gun with a maximum elevation angle of 80 or 90 degrees?"

Gu Lie looked at Lu Yuan with a question mark on his face.

The maximum elevation angle is eighty or ninety degrees??

What kind of gun is this?

Then Lu Yuan shook his head again and said:

"And this cannon is very light, weighing only a dozen kilograms at most?"

Gu Qingwan's face was filled with questions again.

How is this possible!

Although Gu Qingwan on the side did not understand military affairs, she had never eaten pork before and she had seen pigs running away!

During the war, Gu Qingwan often went to the military camp.

The cannons weighed over a thousand kilograms and required seven or eight people to pull them around.

Even if it's small, it still weighs several hundred kilograms.

Ten kilograms??

Is this also called a cannon?

Lu Yuan continued to shake his head and said:

"A squad is calculated as nine people, three people in a group, each person can carry ten rounds of artillery shells, and a squad can carry ninety artillery shells.

If it were you, how long do you think it would take you to conquer a mountain?"

Gu Lie's face was full of questions at this time. After he came to his senses, Gu Lie smiled helplessly and said:

"Brother, what are you talking about...how can someone have that kind of weapon...

If there really is such a weapon... I can lead a battalion for half a day without even using it, I can just blast the hell out of it."

After listening to Gu Lie's words, Lu Yuan also had a smile on his face and said:

"Yes, just blast him."

After saying that, Lu Yuan took out a stack of manuscript paper from his arms, put it on the table and said with a grin:

"And this kind of weapon didn't exist before.

Now that I have it, I call it a mortar!"
