Heavenly Dao Formula

　　 The three of them stood there, with only one thought left in their minds. What happened just now?

　　 The explosion just now sounded earth-shattering, but there was not much damage at the scene, even the weird shelf around Xia Fan looked intact.

　　 Except for the courtyard wall.

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

　　 "His Royal Highness, please be careful!" Qiuyue chased after her body, blocking herself behind the princess, her eyes fixed on the still smoking copper frame.

　　 Ning Wanjun walked to the wall, leaned over and observed for a while, and confirmed his opinion-something penetrated the wall at a very high speed and disappeared outside the villa. The hole was regular in size and there were obvious cracks around it. Unlike a spell, she reached out and explored and found that there was still residual temperature inside.

Although this wall is made of red bricks and is not as hard as a stone wall, it is about ten fingers thick. It is considered to be the thicker section of the outer wall of the villa. It was so easily cut into a hole. She had never heard of it. Shaking technique!

　　 Although thunder is strong, it is difficult to destroy the entity. This is also the common feature of the earthquake technique.

　　 Xia Fan's research has reached this point?

　　 "Your Royal Highness, are you okay?"

　　 "The subordinate just heard an abnormal noise coming from this courtyard, and came here to protect the driver!"

　　 A guard approached at the gate of the other yard, and it was obvious that the huge roar just now aroused their vigilance.

　　 "There is nothing wrong here, you stay outside the courtyard, and don't let other people come near!" 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 an ordinary streamer technique." The latter spread his hand.

　　 "Vibration streamer? Didn't that cause thunder and lightning in the palm?"

　　 "It is true, but when the current is large enough, it can cause some magical phenomena, such as strong electromagnetic force. Of course, this does not mean that it does not exist 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 is also stuck-after all, he is already speaking in the simplest terms. "You can understand that electricity and force can be transformed into each other under certain conditions. Streaming seems to only cause thunder and lightning, but through this guide rail, 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 experiment would be so smooth-after all, this equipment is really crude enough, and the purity of the copper rods is also worrying, even the magnets that are laid under the track to guide the electric field and provide additional magnetic force. The stones were all picked by him from the blacksmith's shop for a long time. The initial expectation was that as long as the projectile was pushed to the wall, even if it was a successful attempt, it was unexpected that the copper cone that served as the cannonball not only hit the wall, but also directly shot through.

　　 This is really incredible.

　　 When Xia Fan cast the streamer technique, he was already aware of the subtle changes in this technique.

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

　　 The streamer of the tremor technique may have carved a unique "mark" in his hands.

　　 Ning Wanjun has another thought in her heart.

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

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

　　 But none of the above is critical.

　　 The key is that it is too fast, so fast that people can't be caught off guard!

　　 She asks herself that she can avoid bows and arrows and crossbow arrows at full strength, but she can't avoid it—even capturing its shooting path with the naked eye is a difficult task.

　　 When the two armies are facing each other, the generals will often stand at the front of the team to observe the situation and take the lead in the charge. What would happen if you suddenly used the shaking technique at this time?

　　 She can see the next scene almost without even thinking about it: the general dies before a battle, the enemy retreats timidly, and her own side takes advantage of the situation to cover up, is there no reason?

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

　　 "Your Majesty, your heart is detached..." Qiuyue reminded in a low voice that it was the first time she saw the princess so excited.

　　 Even the first time she led a battle and won a big victory, she was not so excited.

　　 It's like a child has seen his favorite toy.

　　 "There is no separation between Li and Zhen, and those who suffer from earthquakes often turn to practice Li Shu. I don't think this is a problem."

　　 "But you don't even know how to leave...not a few."

"..." The princess was dumb for a while, her expression was solemn, as if she was engaged in a great heart struggle. After a long time, she patted Xia Fan on the shoulder, "I will learn shaking technique from today. If you don't understand, I hope you Give pointers."

　　Li reached out and put his hand on his other shoulder, the flash in his eyes showed his thoughts.

　　 She wants to learn too.

　　The problem is... the fox demon belongs to the trap, right? Xia Fan was slanderous in his heart, you are not just a gap, you are also a counterpoint.

　　 But he found that he could not refuse the fox demon who was wagging his tail.

　　 "Okay, I will take the time to teach you in the future, ~www.ltnovel.com~ Xia Fan said helplessly, "But this technique is not mature, and there are still many problems to be improved. "

　　 "Immature?" Ning Wanjun asked in amazement. This is called immature, so what does it look like when it is mature? We must know that when the Ministry of Industry meets the demands of the army, it can make do with one less point and not give one more point. "You can never ask it to be as convenient as ordinary alchemy?"

　　 "Compared with a certain junior high school student, it's so much worse." Xia Fan sighed-the conventional problem of railguns, almost none of this test prototype leaked. For example, the cannonball and the track cannot be closely attached to cause the arc to start, and the high temperature generated by the arc will ablate the track; for example, the energy required for its launch is so great that he feels that the qi in the body is consumed by just one time. Seven or eight.

　　 Of course, the most terrible thing is that the discharge terminal must be grounded. If he only relies on his body to complete the current cycle and uses his arm as a guide rail, then when the improved streamer technique flows into the body, he will instantly become a coke.

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

　　 In this way, no matter how strong this technique is, there is no compelling one at all. This is what makes him most distressed.

　　Human...I was still restricted by this body.

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

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

　　 "By the way, why did your Highness find me?"

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

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