Fang Jing went to the miscellaneous room of his own building, and from a small cabinet that was pressed by heavy objects, he took out the gunpowder powder that he had prepared before, although it was not a lot, but it was enough to do a few experiments.

After locking the door, he returned to the hall with the gunpowder powder and handed it to the blue finch, who experimented outside the gate.

"There isn't much gunpowder here, you just need to pour a little bit into it, and then put a small pebble in it, don't put too much gunpowder powder." Fang Jing opened her mouth and explained to Qingque.

Qingque took the gunpowder powder that Fang Jing handed him, and was happy in his heart, this was more pure than the gunpowder powder of his own formula, at least he believed that it was much more harmful than what he had matched, after all, the gunpowder powder was said by Fang Jing.

"Okay, Brother Jing." Qingque nodded excitedly, and then took the musket and gunpowder powder out of the hall, just outside the gate, and began to pour gunpowder powder.

Then they and the beginning of the year stood by and watched, very curious if the musket made by the blue finch could really be fired.

"Qingque, aim at the tree in front, make the fire rope a little longer, after lighting the fire for a while, hurry away for me, who knows if the copper pipe will be blown up." Fang Jing saw that Qingque had finished filling the gunpowder, and then opened his mouth to explain again.

"Okay, Brother Jing." Although Qingque had not experimented with the musket he had created, he still listened to Fang Jing's words, after all, the previous gunpowder matter made him a little scared.

The green finch went to the stove room and took some weeds, rolled them into a small rope, and inserted them directly into a hole at the bottom of the copper pipe, and inside the hole was where the gunpowder was located.

After all the work was done, the blue finch took the flint and began to make fire.

"Wait." Fang Jing was still a little worried, Xiao Linghua at home was sleeping, if it really sounded at this moment, it would be a big start, and it was estimated that she would be scared to cry.

"Let's try it in the bamboo forest." Fang Jing finally decided to go to the bamboo forest to experiment, so as not to scare Xiao Linghua.

Subsequently, the four of them went to the bamboo forest, and several little girls in the family were all playing in the bamboo forest at this time, either digging bamboo shoots for Xiong Er's family to eat, or teasing Xiong Er's family, after seeing Fang Jing and them coming, they all gathered around, wondering what Fang Jing and they were doing here?

"Brother, what are you doing?" Fang Yuan trotted over from not far away, still holding a small bamboo shoot that had not yet been peeled, while Qiuqiu behind him chased after him.

"Brother Jing, cousin." The other babies also came over.

"Stay away, for the Sparrow is going to experiment with his musket." Fang Jing hurriedly blasted the little babies farther away, saving problems from happening.

"Green Sparrow, let's light a fire here, let's all back off." Then Fang Jing instructed Qingque, and he retreated a lot.

After listening to Fang Jing's instructions, Qingque directly began to use flint and steel to start a fire, and then ran away quickly, hiding behind Fang Jing.

"Bang." After a while, the gunpowder powder was ignited, and the pebbles were directly sprayed out, hitting the bamboo not far away, but the sound startled the little babies, the sound was loud and dull.

"Brother, what's that musket? Why is it so loud? Fang Yuan approached Fang Jing, grabbed the corner of Fang Jing's clothes, and carefully looked at the position of the musket.

"The musket is a weapon, it can kill people, this is made by the blue sparrow, let's go over and have a look first." After Fang Jing responded casually, she directly raised her leg and walked towards the position of the musket.

Picking up the musket and checking it, except for the copper pipe being slightly hot, there didn't seem to be any major problem, and the copper pipe mouth was still emitting gray-black smoke.

"Brother Jing, the musket is really okay, look at this bamboo, the pebbles have all been driven into this bamboo, and they have not penetrated." Qingque didn't look directly at the musket, but curiously looked at the bamboos in front of him.

"Well, yes, this musket made of brass is okay, but it doesn't seem to be very powerful, and I don't know how far this shot is." Fang Jing approached the edge of the bamboo with a musket and checked it, the small pebble shot directly into the bamboo, without penetration, thinking that the power was okay, although the distance was only about ten meters, but the power was okay.

Fang Jing thought in his mind, if it was replaced with a steel pipe, wouldn't the power and range be more powerful, or if the pebble was replaced with a steel ball, it would be completely possible to kill a wild boar, right? However, these are all to be experimented, and as for whether they succeed or not, we will have to verify them later.

"Qingque, try one more shot and it'll be over, and when we go back in a while, you guys will check it out." Fang Jing handed the musket to Qingque, shouting for Qingque to try again.

"Okay, Brother Jing." Qingque was very excited at this time, the musket he had built for the first time could have this power, and he thought that if he handed over this musket to his father, how happy his father would be, and he would definitely praise and reward himself at that time.

Qingque took the gunpowder from Dachu's hand and began to prepare for the next shot.

"Brother Jing, okay, where are we shooting this time?" After Qingque had done all the work, he asked Fang Jing for instructions.

"In the direction of the bamboo over there, it's the same as just now, and I'll come back after lighting the fire." Fang Jing didn't dare to let Qingque just stand there with a musket and shoot at the bamboo, who knows what the bearing capacity of the copper pipe is.

"Bang" was muffled again, but fortunately, everyone was prepared and covered their ears, otherwise they would have to be frightened again.

"Yes, yes, this musket is still okay, Dachu, bring the gunpowder home, let's go back." After Fang Jing checked the musket and the bamboo, he was sure that the power and range were still okay, although the range was only about twenty meters, the small pebble still shot into the bamboo, and still did not penetrate.

"Brother Jing, isn't it fun to make a musket made by Brother Qingque? Can I play it once? Li Zhen watched Fang Jing carrying the musket and preparing to walk home, so she ran close to Fang Jing and said to Fang Jing.

"Fun? Didn't you just see that the bamboo was broken by small pebbles? Is your belly harder than bamboo? If your belly is harder than bamboo, I can play with you. Fang Jing felt that this little girl was a little second, such a dangerous thing was fun, and she wanted to have a play, and she didn't know if this little girl's head was caught by the door when she was small?

Fang Jing threw the back of Li's head and went home directly, there was no one at home, if Xiao Linghua woke up, she would have to cry.

After returning home, Xiao Linghua continued to sleep in her big sleep, Fang Jing returned to the hall, sat back on the chair, and looked at the musket for a long time, thinking about how to improve this musket, or how to change the style of the musket, but found that her thoughts were a little too whimsical, not to mention that this musket was Qingque's, and Fang Jing's original intention was not how to improve it herself, but how to improve it by Qingque.

"Qingque, you haven't thought about how to improve this musket? In the past two days, you can write me an idea, and if you write it well, then I will get you a laboratory and let you people who like to do research experiment. Fang Jing stared at Qingque and said.

"Brother Jing, I don't have any ideas for improvement for the time being, but Brother Jing said before that everything has a powerful effect, I wondered, can I build it in a different style, but I haven't thought of how to build it, as long as I think about it, it should be possible." Qingque may not know that what he said was very shocking in Fang Jing's ears.

"Then have you ever thought about it now, the power of this musket you created is not high enough, the copper pipe is not good, after a few more shots, it must be very hot, and the gunpowder remains on the inner wall of this copper pipe, which will also hinder the launch of small stones, and small stones are easy to scatter, you should think about how to solve these." Fang Jing casually brought up some problematic points, so that Qingque could use his brain to think about it.

"Brother Jing, can you give me that steel pipe? By the way, cut the steel pipe shorter, so that the copper pipe can be heated, as for the inner wall of the copper pipe if there is gunpowder slag remaining, when the time comes to shoot a few shots, it can also be cleaned once, this can also solve the problem, the small stone is easy to split, and I should be able to replace it with iron beads at that time. Qingque listened to Fang Jing's questions, and casually told Fang Jing his solution directly.

At this time, there was only one thought in Fang Jing's mind, 'I'll go, is this a demon?' I just ask a few questions, and he can think of a way to solve them? Or am I not having enough brains? Am I old? Fang Jing didn't dare to believe that Qingque was so smart, and felt that he had mistaken a future scientist for so many years, and began to regret it in his heart.

"Qingque, these problems are just small problems, as a scientific researcher, you have to list more paths, one by one to verify, even if it is a wrong path, you have to verify, because you don't know that he is wrong before you have an experiment, and, in addition to the problem to be solved, you also need to know how the problem is generated, and you must know the specific standards and values, so that you can have data as a reference in the next experiment." Fang Jing continued to develop towards the blue sparrow.

"Brother Jing, I don't know what you're talking about, you didn't let me do any experiments before, I could only do it secretly, so there was no experimental data." Qingque had been hiding from Fang Jing to conduct experiments or create something before, but now that the musket he made was discovered by Fang Jing, he originally thought that this beating was indispensable, but he didn't wait for Fang Jing to beat him, but Fang Jing was willing to get him a laboratory or something.

"Okay, as long as you do experiments, I will support it, but you have to report to me first, except for gunpowder and some large-scale experiments that require me to be present, other small experiments, you can do whatever you want, but in some dangerous experiments, you must ensure safety, remember, do any experiment, you have to tell me." After listening to Qingque's words, Fang Jing thought for a while before saying to Qingque.

"Brother Jing, what you said is true? I can really go and experiment, you can't lie to me, right? Also, you're not going to trick me into doing an experiment and beating me up, are you? After listening to Fang Jing's words, Qingque was a little scared in his heart, afraid that Fang Jing would deliberately hang his appetite, or even throw out a bait.

"Don't worry, I won't do anything to you, as long as you report to me during the experiment, but every time you experiment, there must be a data record, otherwise, your experiment will be in vain." Fang Jing nodded and confirmed to Qingque.

Fang Jing's original intention, as long as Qingque didn't do some dangerous experiments, Fang Jing would follow them, but since Qingque and the two of them were discovered by Fang Jing last year when they were engaged in gunpowder experiments, they may have been too worried, so they were strictly stopped from doing any experiments, not to mention that children's hearts are not easy to control, but now that this thing has happened, and they can't control it, it is better to let it go directly, and the control on the surface is better than for them to sneak around.

After listening to Fang Jing's words, Qingque was so happy that he couldn't find the north, hugging and shouting, he didn't know how to describe his excitement at all.

Fang Jing's scientific research momentum for Qingque in his heart is really a little terrifying, maybe there will be more terrifying places that can make Fang Jing in the future, for now, it has made Fang Jing convinced that Qingque is a scientific research talent, maybe in the near future, he can really become a great scientist, it is better than him dying in rebellion.
