Zhang Xiaoheng asked, "Just ask everyone, can you hear the voice clearly?"

Sikong Shou said excitedly: "Clear, very clear! It's so clear! My Sikong Shou speaks counts, I'll go to the book to ask for a first-class military merit for you! With the microphone and headphones, what else do you want to do with the flag? Next time, we can catch them off guard!"

"Hahahaha! Congratulations to the general, congratulations to the general!" For a while, everyone rejoiced, as happy as if it was the New Year.

Mei Huang suddenly stood up: "Slow, General Sikong, isn't it too hasty to do this?" The value of this thing, everyone has seen it, this is a new spiritual weapon that will definitely be promoted, even in Xixiu City, where we have 200,000 defenders, it will be at least hundreds or even thousands of copies, considering the need for temporary command replacement, I am afraid it will increase a lot, and this thing is not only made once, it is not certain how much will be made in the future, it is estimated that the seven peaks of Moyu can be used, and the 25 border cities can be used. Think about it, if you don't count other big cities in the country, you have to make tens of thousands of new spiritual weapons, and you will be sent away with a single military merit?"

I didn't expect Meihuang to have such a side, as a mentor, he stood up and fought for the benefits of his own people.

"Huh?" Sikong Shou touched his head, but was accidentally pierced by the general's helmet on his head, and the man quietly withdrew his hand and said, "That's reasonable, so in your opinion?"

Mei Huang said: "Military merits naturally have to be remembered, in addition, I will report to the sect and notify the sect of the new secret recipe specifications, of course, he created this secret recipe because of the requirements of Xixiu City, as long as the military camp contributes to the materials, he should give priority to teaching the craftsmen of the city and giving priority to equipping the defenders of the city." ”

Everyone nodded.

It turns out that if the reward is set up with the specifications of the new secret recipe, it will be completely different, which means that the sect does not give a one-time reward to collect the recipe, but as long as someone uses it, it has to give the sect and the formula inventor a certain share, such a system is applicable to Danfang, formations, drawings, etc., that is, the creator of the new secret recipe can always get benefits, as long as it is assessed as a secret recipe.

Sikong Shou nodded: "That's right, that's right, I think this new spirit weapon can not only be recorded in the secret recipe, but also put it in the spirit stone, so as not to be learned by other countries." ”

Mei Huang said: "Then it depends on whether this recipe is easy to learn." "Indeed, if it's too easy, even if you use the spirit stone, it's useless, you can't guarantee that others won't take away a finished product, go back and study it yourself.

Zhang Xiaoheng shook his head: "It's just the transmission and reception of sound waves, in fact, the core technology is very simple, I understand the principle of the spirit stone, but it's really not difficult for me, otherwise, how can I get it out in three days? As long as someone learns it, it's really easy to teach others." ”

"So?" Sikong Shou frowned: "Then you can only deal with it according to the ordinary secret recipe, but unfortunately, in this way, the value will be discounted." ”

"That's not a problem, in fact, I think it's okay, as long as you understand the basic principles of sound emanation, transmission and reception, imitation is not difficult, and drawings are not the only option at all. Zhang Xiaoheng said: "I just did a little processing, the transmission part is this microphone, after the sound, through the phase-locked loop and voltage control oscillator to generate the RF carrier signal, the signal through the buffer amplifier, excitation amplifier, power amplifier amplification, through the filter to eliminate the harmonic components, through the microphone to send out. ”

"This headset is a one-way receiver, the principle is simpler, can only amplify the corresponding wavelength of the signal, that is, through the phase-locked loop frequency, the first local oscillator signal is mixed at the first mixing frequency, claiming the first frequency signal. That is to say, with a frequency receiver, you can receive sound waves, but to hear clearly, you also need to mix with the second local oscillator signal through the intermediate frequency processing chip, and finally, use a miniature ceramic filter to filter out useless signals, amplify, and discriminate the frequency to generate audio signals, and then through signal amplification, band-pass filters, de-emphasis, volume control, power amplifiers and other circuits...... Drive the speaker to emit ...... Sound ......"

"Difficulty...... It's just on the chip board, what's wrong with you...... Why are you all looking at me with this expression?"

Angry Green looked confused: "Brother arrogant, I won't ask anything else, that ...... What is a circuit board?"

Zhang Xiaoheng was stunned, he suddenly understood, not to mention the circuit board chip, a series of terms he said just now, what buffering, mixing, wavelength or something, I'm afraid they all understand it, otherwise, how could they see the victory of a group of bigwigs in front of him with dozens of faces?

Sikong Shou suddenly said: "I suddenly feel that there should be no problem with using the Spirit Carrying Stone, otherwise...... I'm afraid that no one will understand the drawings, do you agree?"

That's right, the people present are not fools who have never seen the world, but the elders of the sect and the generals of the unified army, no matter how high or low they are, they are at least people who are proficient in a spiritual art, and even they don't understand it, this thing dares to be said to be simple?

Zhang Xiaoheng also suddenly realized that the direction of the Jade Realm's scientific and technological talent tree plus points is completely different from that of the earth, and the Jade Realm is at least a whole book short of basic physics and electricity from such things as microphone walkie-talkies.

"Ahem, by the way, General Sikong, I want to make a suggestion on the use of microphones and headphones. Zhang Xiaoheng simply didn't bother to dwell on this issue, so he simply pulled the topic back and explained the principle to them, purely to find trouble for himself.

Sikong Shou nodded and said, "Please speak." At this moment, Sikong Shou's attitude towards this student has changed from heavy to respectful, and when he spoke, the specially pretended "I" didn't say anything, and now when he speaks, he has an extra word "please".

Zhang Xiaoheng said: "This set of equipment is one-way information reception, well, that is, only people wearing headphones can hear, so I suggest that the flag law remains unchanged, simply add headsets, once the flag bearer is controlled by the enemy, the rear commander immediately informs the front to order the flag bearer to change, so that the command will never be interrupted." ”

"General, on the battlefield, it is changing rapidly, and the addition of a communicator can leave more space, otherwise, it is necessary to equip each soldier with a headset, but in this way, the effect is not as good as a simple front flag. ”

Sikong Shou thought for a while, frowned, and said: "It makes sense, the purpose of the communicator is also to make it more convenient to command." ”

Zhang Xiaoheng said: "Moreover, our order flag is still there, and it can still confuse the enemy on the battlefield, if they cut the flag and destroy the order, let them succeed, let them think that the order flag is lost, and the formation is bound to be chaotic. ”

......

After another two days, the Baiyu border army reorganized its troops to fight again, and only five days later, they had basically recovered their vitality, and now the mourning soldiers are fighting again, and their morale is very calm.

At the beginning, it was a routine insect and beast game with each other, shooting at a distance. After clearing the traps, plant spirits, etc., this is the time to enter the melee confrontation link.

In the past, in the melee attack stage, the Moyu Border Army would always firmly gain the upper hand with its lifeless and brave style, but today it was a little different, a team of fourteen Nine Rank Spirit Masters suddenly appeared in the White Jade Army, and they just formed two sets of positive and negative seven-star arrays, suppressing the Moyu Vanguard Army to the death.

In this way, the morale of the white jade army was greatly boosted, and he immediately slammed it head-on, rarely suppressing the black jade army.

The fourteen-person team of pure nine grades was not satisfied, but after seeing that they had gained an advantage, they killed all the way to the place where the Moyu Ling Bannerman was, their speed was extremely fast, and the purpose was to cut the flag and destroy the order!

The strong people who enter the Dao are not allowed to join the mortal battle, so the team composed of all the nine rank spirits is already standing at the peak of the combat power in the mortal battle, besides, these fourteen nine products also form a positive and negative Liangyi Seven Star Array, with the broken army as the main force, the formation has developed the killing power to the extreme, and it is really a bit invincible to kill all the way.

Finally hit the Lingqi guard, the fourteen people encountered a tragic resistance, the soldiers rushed desperately, stubbornly resisted, in the Moyu army array, how can you be allowed to enter the realm of no one? For a while, the Moyu army thought that it had blocked this positive and negative Liangyi Seven Star Array.

However, this was just an illusion, the positive and negative seven-star arrays suddenly changed formations, the main star was changed from a broken army to a greedy wolf, and the fourteen nine-rank spirit masters neatly cooperated with the cunning greedy wolf to bypass the escort team and go straight to the command flag!

The banner fell, the Moyu army began to be chaotic, the morale of the Baiyu pioneer battalion was greatly boosted, and the combat effectiveness seemed to be greatly improved, and the Moyu army was defeated and retreated, and an iron army that had been stationed on the front line for a long time began to retreat.

The white jade army frantically killed, and the black jade army could no longer resist it, and retreated like a tide.

Victory! Victory is at hand! Victory is just around the corner! The white jade army is extremely excited, the vanguard team that killed first and the fourteen spirits who have made great contributions will join forces in victory, and with the momentum of great victory, the white jade vanguard army will take advantage of your illness to kill you!

Suddenly, the white jade pioneer battalion knocked out a burst of golden sounds, heard the drum charge, Ming Jin withdrew the troops, on the battlefield, Ming Jin clearly means to collect the troops, but why? Obviously the big victory is imminent, why suddenly withdraw the troops?

Just when there was some confusion in front of him, he saw that the officers and soldiers of Moyu Zhongjun had completed a change of formation in an orderly manner, the shield soldiers took a step forward, and the rout soldiers took a step back, just behind the shields. And after the shield, the pikemen are already in full array, do you dare to rush into battle? Then I will not only block you, but also stab you into honeycomb coal, even if it is an ordinary weapon, as long as there are too many, it can also pierce the spirit shield of the spirit of the soul of the soul of the enterer.

At the same time, two teams of men and horses suddenly came out from the left and right, and they would enter the formation of the Moyu Army, and there were thousands of pioneers of the White Jade Army who cut off their waists, and at the same time, dense bows, spiritual methods, and flying stones were neatly shot down from the sky, almost in an instant, all the soldiers of the White Jade Army who were surrounded in the middle were injured.

At the same time, a loud bang rose from the white jade camp to the sky, and the soldiers of the white jade country heard the sound and looked back, but saw a rainbow floating in the sky.

Victory and defeat, in the blink of an eye, inexplicably changed hands.
