Wang Zhirong rushed to the place where the sound sounded, and saw Kong Ming still standing in the distance......

It's good if people are okay, it's good if people are okay!

If this guy came to this world because of Wang Zhirong and made this thing, he would have killed him early...... Then the joke is bigger......

"Kong Ming, are you alright!!?"

"Teacher, the student is okay...... It's just that this thing is not easy to control the direction, it deviates too much, and it explodes in the air......"

"It's good that people are okay!"

At this time, there were already many students who rushed over after hearing the sound, and Wang Zhirong persuaded him to go back......

Wang Zhirong said, it's nothing, it's just that he taught Kong Ming the Five Thunder Rectification, and this guy accidentally attracted a thunderbolt when he was cultivating......

Everyone was thundered by this sentence!

You didn't forget your brain on the pillow, it's all in your head now......

No one believes this nonsense, but everyone knows that there are some things that people of their level can't get close to......

All the teacher's arrangements are correct and reasonable! All the teacher's orders must be resolutely carried out...... If they are not allowed to get closer, they can only leave with amusement......

In fact, the explosion of black powder 🔥 has been witnessed by everyone in front of us once......

At that time, Wang Zhirong only had two disciples: Wolong and Phoenix.

Xu Shu and others are still in the probationary stage and belong to the people who eat melons......

In order to tell them about strength and truth, it is only within the range of artillery...... Wang Zhirong remembered that he had a shot at the beginning!

Using a clay pot filled with black powder 🔥 mixed with iron sand can be regarded as a soil bomb: bomb...... At that time, everyone was shocked...... It was unforgettable......

Everyone felt that they were towering and unfathomable, and this cannon played a great role in the beginning!

However, everything has to be mysterious to be a deterrent, and most importantly, to keep it secret......

Now these students of his own, he still believes it, but this thing is too important!

Once it spreads, how many white bones will be added to the vast land, and how many orphans and widows will be added to the world......

So no matter what, it's better to hold this thing in your own hands......

"Can fly, can blow up...... It's just that the time and direction of the explosion are not easy to grasp......"

Wang Zhirong took a look at the few ...... that Zhuge Liang had already made

One has exploded, and there are three left, all of which are exquisitely done, but it is obvious that the thinking of liberal arts students is too lacking in calculation......

What he made was to enlarge an arrow and tie a bamboo tube of black powder 🔥 to it......

The result is that the front is heavy and the back is light, the left is heavy and the right is light, in short, the overall seems to be very unbalanced......

Once the balance of this kind of thing is broken, the direction will naturally be off, it is difficult to grasp, and it needs to be calculated...... And it's a particularly difficult mechanical operation......

Wang Zherong is a student of biology, and science students are also involved in this aspect, but he is too lazy to use this brain......

The thing that came out in front of me is actually a rocket principle, which needs to be calculated using the principle of aerodynamics, which is difficult to ......

Anyway, there is time, so leave it to Kong Ming and others to experiment over and over again, and slowly draw some experience and data from the experiment.

Someday it will be done...... After all, the fuel is loaded into the bamboo tube, and the basic principle is here, and at this point, it is considered to have reached ninety-nine steps, and it is almost the last one.

Things beyond the scope of nine-year compulsory education, Wang Zhirong doesn't plan to get too much into this world, teach some basic things, and let the people of this world take some paths themselves......

You can't always put everything up in a big way, the so-called Shengmien, Doumi hatred......

At any time, people can't be too accustomed to it, and they need to be beaten with a big bamboo stick to be grateful, and they will forge ahead......

"Kong Ming is a person with seven knowledge! As a teacher, I believe that you will definitely make this thing right...... The length of the bamboo, its thickness, its straightness, the balance that needs to be paid attention to after tying several things together, etc...... You can experiment over and over again...... Then you'll find out what's here......

There are some things that we are far less than an experienced craftsman......

On the basis of not leaking secrets, you can ask them and learn from them......"

"Teacher, when you said this, the student suddenly seemed to understand something. Students should follow the teachings of their teachers......"

The remaining ones are not let go, and Kong Ming also understands that the thing he made is much the same, and it is not much different from the one that has been blown up before......

If you continue to experiment, there is no point, it is better to go back as soon as possible and improve as soon as possible...... So he picked up the remaining three and immediately took his leave......

Look at his nervous state, he has completely fallen into it, and he is crazy......

Pang Tong's thing has actually been formed a long time ago, and what needs to be done now is to make it big and sturdy, and then it can really take one or two people on the flight......

When Wang Zhirong came to Pang Tong's side, it had already been completed, and the work of silk sewing and glue brushing called a few women to help, and the work was done very carefully, and Pang Tong even made a huge bamboo frame......

"You think this thing works?" Wang Zhirong kicked the bamboo shelf.

"......" Pang Tong thought sideways for a while, and looked like he suddenly realized: "It's really useless, after the gas is full, the shelf is useless at all!" But at first...... You can use a bamboo pole to stretch it out a little casually, and after a while, after the gas is full, you won't need it......"

"Now you want to make sure that your thing is really strong, I suggest getting three layers and a silk rope net around the outside, so that it is safe......

Of course, this is a measure that needs to be guaranteed when you become a master in the future, and now you can come up with an experiment to put pigs, sheep and dogs first......

You must adhere to the experimental spirit that the teacher told you, and you must use evidence and data to speak......"

Pang Tong nodded like pounding garlic: "The teacher always has the words to see the sun and turn stones into gold!" ”

This is Xu Shu also coming in......

"Teacher, with ten pieces of red, white and blue colored flags, you can get countless kinds of ......"

Crackling! The big bamboo stick hit Xu Shu's body again......

"As a teacher, I hate countless people, probably, probably, probably...... There are limits to this permutation...... You take your time! ”

"Teacher, students must pay attention to accuracy and precision, and resolutely abandon the stinky habit of literati speaking......"

"Good! It's good to understand! ”

"Now the situation in the arrangement corresponds to one commonly used word, and two hundred and thirty-two commonly used words have been obtained! The message is sufficient...... The reason why the students came to Shiyuan was to combine this transmission system with his flying ball......"

"Good! That's a good idea......"
