The three of them froze in place, with only one thought left in their minds, what had just happened?

The explosion just now sounded earth-shattering, but there wasn't much damage at the scene, even the weird shelf around Xia Fan seemed intact.

Except for the courtyard wall.

Ning Wanjun took a deep breath and strode towards the entrance of the cave.

"Your Highness, please be careful!" Qiu Yue chased after her, blocking herself behind the princess, her eyes staring at the still smoking bronze frame.

Ning Wanjun walked to the wall, leaned over to observe for a while, and confirmed his opinion—something had penetrated through the wall at an extremely high speed and disappeared beyond the villa. The hole was a regular size, and there were obvious cracks around it, not like it was a spell, and she reached out to probe it, and found that there was still residual heat inside.

Although this wall was made of red brick, it was not as hard as the stone wall, but it was about ten fingers wide, which was the thickest part of the outer wall of the villa, and she had never heard of a similar seismic technique!

Although the thunder is strong, it is difficult to destroy the entity, which is also a common feature of seismus.

Xia Fan's research has come to this point?

"Your Royal Highness, are you alright?"

"My subordinates just heard a strange noise coming from this courtyard, and they came to escort them!"

There were already guards approaching the gate of the courtyard, and it was obvious that the loud roar just now had aroused their vigilance.

"There's nothing going on here, you stay outside the courtyard, don't let the idlers and others get close!" Ning Wanjun said decisively.

"Yes!"

Then she couldn't wait to look at Xia Fan, "Can you explain this technique for me?"

"It's just a normal streamer. The latter said.

"Seismic streamer? Doesn't that cause lightning in the palm of your hand?"

"Yes, but when the current is large enough, it can cause some magical phenomena, such as the generation of a strong electromagnetic force - of course, this does not mean that it is not there when it is small, but it is difficult to attract people's attention. ”

Ning Wanjun was silent for a while, "...... Can you make it easier to understand?"

Xia Fan was also stuck—after all, he was already in the simplest terms. "You can understand that electricity and force can be converted into each other under certain conditions, and the streamer seems to just cause lightning, but through this guide, it can be turned into a huge thrust. ”

This is also the principle of the railgun.

In fact, Xia Fan himself did not expect that the first test would go so smoothly - after all, the equipment was rudimentary enough, and the purity of the copper rods was also worrying, and even the magnet stone that was laid under the track to guide the electric field and provide additional magnetic force was picked up from the blacksmith shop after half a day's work. At first, it was expected that as long as the projectile was pushed against the wall, it would be a successful attempt, but the copper cone that acted as a cannonball not only smashed into the wall, but also shot directly through the wall.

It's kind of incredible.

When Xia Fan cast the Streamer Technique, he had already realized that this technique had undergone a subtle change.

For example, at this time, the condensed qi is no longer lively and rough, but thick and stable, like a rolling torrent.

"The most important thing in magic is what you think. 」

"Even if it's a spell with the same attribute as oneself, it will vary greatly from person to person—it depends on proficiency, comprehension, and personal perception. 」

The seismic streamer may have carved a unique "mark" in his hands.

Ning Wanjun had another thought in her heart.

If this thing can be put on the battlefield, it will definitely be a great weapon in the army!

A few copper shelves are much lighter than iron cannons. And this thing does not need flammable materials such as saltpeter and toner from beginning to end, and will not kill itself in turn.

But none of the above is the point.

The point is, it's so fast, so fast that it catches people off guard!

She thought to herself if she could avoid bows and crossbows at full strength, but she couldn't dodge them - it would be difficult to even catch its path with the naked eye.

When two armies face each other, the general will often stand at the front of the line in order to observe the situation and take the lead in the charge. What would happen if you suddenly used a seismic technique at this time?

She almost didn't have to think about it to see the next scene: the general died before the battle, the enemy retreated timidly, and her own side took advantage of the situation to cover up and kill, how could it be unreasonable?

"Can I use this spell?" Ning Wanjun's tone burned.

"Your Highness, your heart is detached...... Qiu Yue reminded in a low voice, it was the first time she had seen the princess so excited.

Even the first time she led her troops into battle and won a big victory, she had never been so excited.

It's like a child seeing their favorite toy.

"There is no separation between the earthquake and the earthquake, and the earthquake people often switch to the cultivation of the separation technique, I don't think there is a problem with that. ”

"But you can't even ...... the technique There won't be a few. ”

"......" The princess was dumbfounded for a while, her expression was solemn, as if she was engaged in a great mental struggle, and only patted Xia Fan's shoulder after a long time, "I will start learning the earthquake technique today, if you don't understand it, I hope you will give me more advice." ”

Li Ze reached out and put his hand on his other shoulder, and the glint in his eyes had already revealed his thoughts.

She wants to learn too.

The question is...... The fox demon is a Kan, right? Xia Fan slandered in his heart, you are not only in the next position, but also in the right place.

However, he found that he could not refuse the fox demon with its tail wagging at all.

"Okay, I'll take the time to teach you later. Xia Fan said helplessly, "However, this technique is not mature, and there are still many problems that need to be improved." ”

"Immature?" Ning Wanjun said in surprise, this is called immaturity, so what should it look like when it is mature? You must know that when the Ministry of Industry meets the requirements of the army, it will make do with less and give no more. "You can't ask for it to be as easy as a normal spell, can you?"

"It's so much worse than a certain high school student. Xia Fan sighed - the conventional problem of the railgun, almost none of the test prototypes were missed. For example, the cannonball and the orbit cannot fit tightly and cause the arc to be triggered, and the high temperature generated by the arc light will ablate the orbit, or the energy required for its launch is so great that he feels that the qi in his body is consumed in just one cast.

Of course, the most important thing is that the discharge end must be grounded, if he only relies on his body to complete the current cycle and uses his arm as a guide rail, then the moment the improved streamer technique pours into his body, he will instantly turn into a coke body.

This means that in the future, as long as Xia Fan wants to use this trick as a killer weapon, he must carry a heavy metal shelf on his back and make sure that it is well grounded, otherwise it is no different from suicide.

In this way, no matter how strong this technique is, there is nothing to force it to speak of, which is the most painful thing for him.

Man...... Still confined by this body.

The more he studied the arts, the more Xia Fan felt so.

It's a pity that no one can understand this regret except himself.

"By the way, why did Your Highness come to me?"

Xia Fan didn't think that the other party was idle and happened to come to him.

Ning Wanjun nodded, "I just want to tell you that I have already recruited all the people you need to make salt." ”
