King Qin, naturally you have to show the attitude of King Qin.

Because I am not familiar with artillery operation, Dai Luyou transferred to me a deputy she had just trained, called Xiao Nu, a Kunlun slave, who felt uncomfortable with the hot summer race, black, but it was not a Feizhou race, it was probably a person from the southern mute area, a female ghost of the Tang Dynasty.

Not to mention, although it is black, this little slave's facial features are very chic, combining the advantages of Chinese and Western races, and his figure is even more popular.

She was really smart, and brought the protractor and triangle I bought for Dai Lu, as well as a notebook full of data and tables, which she wrote herself, which was equivalent to the notes she learned from Dai Lu, and it was full of artillery ballistic data.

And these data are already in Dai Lu's head.

It took nearly half an hour to load the truck, fifty horse-drawn gun carriages, the shells were not loaded separately, but scattered on each gun carriage, their shells were not large, sixty in one car, that is, two large wooden boxes.

After loading, Bingbing, Baobao, and Xiaonu and I set off with the team.

Fortunately, the surrounding area is controlled by the imperial court, Zheng Baobao scattered sixteen rangers in eight directions to ensure the absolute safety of these baby bumps, and after walking smoothly for three hours, a row of mountains appeared in front of him, which was not very steep, Zheng Baobao said, over the mountain, from Erqi City, it was only ten miles away, if the enemy set up an ambush, it was likely to be in the mountains.

"Then you rest in the forest first, and I'll go investigate." I say.

"Brother, I'll go with you." Bingbing said, I nodded, she actually wanted to take the opportunity to learn the Wind Technique, or better, that thing was easy to learn and easier to use.

It took a minute, I taught Zheng Bingbing to use the Wind Technique, and I didn't hide it from others, no need to hide it, it was useless for them to learn it.

The two of them turned on the wind trick at the same time, and soon reached the top of the mountain, but Bingbing probably because of nervousness, did not brake the car, ran directly down the mountain, rushed to the plain below the mountain, and rushed into the dense enemy camp, she remembered to turn around, drew a big arc on the periphery of the enemy camp, and ran back to the top of the mountain, but still couldn't stop, I had to step on the step, synchronize with her again, and tell her how to stop.

"Stop!"

Smooth landing.

Along the way, I opened the wind trick and the phase qi technique at the same time, and did not find that there were ambushes on the mountain, of course, if there is a structure similar to the hidden soldier cave in the mountain, my phase qi technique is invisible, standing on the top of the mountain, observing the situation of the great plain below, at a glance, this Erqi city, is actually a lonely city, all sides are land, three sides are plains, only one side is backed by the mountain, and this mountain, is an arc-shaped mountain, around a large circle, connected to our feet.

The last time I saw this kind of mountain was when I was in Tianchi in Changbai Mountain.

"Is this a crater, or a crater?" Bingbing has been engaged in outdoor sports all year round, and when I saw the doorway at a glance, I suddenly realized that the crater is similar to the moon.

"I don't know, it's not such a big crater, it should be a crater." I analyzed.

Bingbing stretched out his thumb and compared the distance: "It's too far, if you set up a position on the top of the mountain, I'm afraid you won't be able to bombard the enemy."

"You also know how to distance with your thumb?" I was surprised and asked, "Isn't that the expertise of artillery?"

"We can also use it for mountain climbing in the wild, don't underestimate people!" Bingbing pouted.

Okay, I believe her, in fact, she doesn't need to be measured, she definitely can't hit it, and the range is not even half of it, because this crater is too big, if you want to bombard the enemy camp, you have to at least pull the cannon to the foot of the mountain and a kilometer ahead.

But in that case, the artillery would be hit head-on by the cavalry, and although the artillery was fierce, it could not stop the fast cavalry of the underworld.

You can't do it brutely.

"Bingbing, you go back and give the order, let them stay on standby, and I'll go and seek the cooperation of your neighbors." I say.

"How can there be a friendly neighbor?" Bingbing asked.

"Didn't the baby say that twelve detachments had been mobilized," I gestured with my hand to the crater, "no matter which direction they come from, they will have to climb to the top of the mountain to reconnoitre, just like the two of us, as long as I follow the ridgeline, I will meet them."
