The next day, Bai Qing and the soldiers arranged by Cheng Feng left with the letters, and they had time to spare, so they came to Qi Ke to see the launch test of the explosive package.

The soldiers who harvested the pigs and shaved the roots had breakfast and went up the mountain early in the morning, and this time there were also Fu Xiaoli and the three boys, so it was too uncomfortable for them to play in the village for a few days with nothing to do, so it was better to go to work together and see the scene of the harvest.

Ding Lin and the three girls were left behind, Qi Ke meant to go and see it, there was no need to work, the men were so hot that their shirts were put on their bodies to wipe sweat and sunburn, and the women mixed in with a hot sweat button didn't dare to untie two more, why bother to suffer.

The girls laughed and laughed, thinking that the scene was really indecent, so they didn't make trouble going up the mountain again, but went to the inn to help dry the pig's roots, which was easy and not tiring, and after turning it over, they could go to the shade to rest.

Just sent the girls to have fun on their own, Bai Qing and Cheng Feng came to the door to see the launch test, fortunately yesterday was ready, Qi Ke and Zhaolin took the things in front of the road to lead the way, or took yesterday's gondola platform uphill, along the mountain road through the hot pig digging root field, and then went more and more deviated, and finally came to the small valley where Qi Ke demonstrated a dynamite package test.

"I'll go in and check the target, are you two waiting at this entrance? I'll be out soon. ”

"No, let's go in together, I'll see the actual distance between your target and here, let's do a few more tests, and pull this cannon barrel down."

"Okay, Mr. Qian has the final say."

Qi didn't understand what the Bai family army was particular about in the practical test of ordnance, what Bai Qing said was what he wanted, he could see it.

Zhaolin noticed that Bai Qing and Chengfeng were not blind, starting from saying that they wanted to see the distance on the ground, the first step of the two of them into the valley was different from the pace they had walked all the way before, and the steps became rulers, and the spacing between each step was equal, which was really a measure of the firing distance of the cannon barrel with their feet.

Seeing this, Zhao Lin didn't say anything, but stepped up to chase Qi Ke, and the two teamed up to lift out the scarecrow target of the tool shed and insert it into the soil.

This test had to be done several times, and several grass targets had to be used up to demonstrate the firing distance of the cannon barrel, and there was always the difference between the closest and the farthest.

Qi Ke and Zhaolin erected the first grass target, Bai Qing and Chengfeng also measured it with their footsteps, and then the four of them retreated to the entrance of the small valley together, Zhaolin untied the burden on his hand, Qi Ke took a shovel and dug a pit in the ground, ready to bury the cannon barrel half-way.

"To use it like this? Can't just put it on the ground? ”

The beginning of the demonstration is the beginning of asking questions, no matter how naïve the question feels, there is a need to ask questions, not only now Bai Qing and Cheng Feng have to understand, but they will have to write it word by word when they report to the general in the future.

"No, it must be compacted with soil, otherwise at the moment of launch, the barrel will be displaced, and once it is displaced, it will be difficult to say who it will hit."

"It's possible to hit your own people?"

Qi Ke held the barrel of the cannon and put on a posture of the barrel facing the sky, "Because this barrel is light, it is not a cannon to be pulled by a horse in the army, it is placed directly on the ground, as soon as it is fired, the muzzle of the cannon is raised, where do you say the explosive package will fly?" ”

"Okay, let's send it to us first."

"Stand out of the way."

Bai Qing and Cheng Feng stepped aside, and Qi Ke neatly buried the cannon barrel in the soil, put in the explosive bag, checked the lead, ignited, and fired.
