It's not far from Lao Cui's City God Temple, I sent the girl directly to him, let me assign a good place, Lao Cui checked the girl's file, this girl is a college student, a blank piece of paper before her death, she was hit by a car or to save a school girl, and pushed the school girl away, but she didn't dodge it, and she belonged to a person with "merit".

I arranged to go to a city without war, and I personally sent the girl to the ghost gate, sent it to Meng Po, and bought her two cups of coffee, drank it on the way, and then sent it to the small train, telling the girl not to be afraid, just start a good life in the underworld.

Although the girl was a ghost for the first time and didn't understand anything, she also thanked me a thousand times, saying that if she was reincarnated, she would repay me as a cow and a horse.

"Haha, if you want to repay me, it's better to be a man, I don't like beef very much." I laughed.

The girl blushed, stood in the car, and bowed deeply: "Anyway, thank you, sir!"

Because the cheongsam ferryman received a short notice, there were two ghosts behind him, on the way, late, and needed to wait for a while, so I sat in the car and chatted with the girl for a while, saving her loneliness.

Through small talk, I accidentally learned that she was actually a junxiao student, and she was still studying the unpopular major of artillery command.

"You're a girl, learning artillery command?" I scratched my head.

"Well, because my grandfather was an artillery commander back then, and my father and uncle were also artillery coffins, and my generation has no brothers, only sisters, and I, as the eldest sister, have to learn this in order to comply with my grandfather's wishes, which can be regarded as inheriting the family business." The girl smiled heartily, but she didn't feel that she was so wronged, and there may be girls who are naturally interested in these sometimes cold, sometimes hot steel machinery.

"So how far have you learned? How old is it?" I asked.

"I'm a senior in college, and if it weren't for the accident, I would have officially enlisted in the army next year." The girl spread out her hands, although her hands were white and tender, small and delicate, but the palms had a lot of thick calluses, which should be caused by the perennial practice of carrying cannonballs, which was regarded as a meritorious medal for the students of the Junxiao Academy.

"Senior year," I nodded, lighting a cigarette, "then you're pretty much done with what you're supposed to learn, right?"

"Well, the courses are over."

"Then I'll test you," I said, puffing on my cigarette, "what's the range of the howitzer?"

"Different howitzers have slightly different firing ranges, take our more advanced PLZ-07 self-propelled howitzer as an example, its high and low firing range is 0 to 70 degrees, and the left and right are 360 degrees without dead angles."

"Self-propelled howitzer...... Something like a tank?" I don't quite understand.

"Uh-huh."

"So, old artillery, do you know how to handle it?" I asked again, there was nothing as advanced as a self-propelled gun in the underworld for her to fiddle with.

"It's a metropolis, although some of us haven't seen the real thing, but we have learned the theoretical knowledge."

"And what if it's an ancient cannon?" I asked again.

"Ancient? Ancient artillery was simpler."

"Ancient artillery didn't have a range meter or anything like that, and it could be used well?" I asked.

"The ruler, the firing range and so on can be calculated through the exercise, any kind of cannon, give me half a day, I can make its range reference table to calculate the distance through the elevation angle."

"Trigonometry, right?" I asked.

"Well, we don't need calculators, pens and paper, just some of them can even do the math." The girl said proudly.

This is understandable to me, probably in the field combat environment, if any advanced technology and instruments are destroyed, even if there is no calculator, how to make the weapon continue to play effective, combat effectiveness, this is what they need to master, just like Yan Xia has always kept a mental arithmetic team, the members are outstanding young people in the field of mental arithmetic, and some are even children, just to simulate that extreme battlefield situation to ensure that in that situation, there is still the ability to counterattack.

"That's good, you wait, I'll call." I took off the Soul Detention Order and called it directly to Little Yama, which was a pure windfall.

After connecting it, listening to the voice of the little Yama is like sleeping, although there is no day and night in the underworld, but the ghosts also need to rest, and they can't be tired of life and death.

I gave a brief introduction to the girl, but Yama said that they didn't have much artillery for the girl to command.
