Under the call of His Majesty Ren Tianming, the Emperor of the Sonorous Empire, all the patriotic dead soldiers of the Sonorous Empire gathered in their imperial capital. Long Ming could clearly feel this phenomenon, because as soon as these patriotic dead soldiers left, the rest were only those who abandoned the city and surrendered.

"Lord Wang, now we are getting closer and closer to the imperial capital of the Sonorous Empire, but their guards will not resist and surrender soon, is there any conspiracy?"

"They really have the strength, and the people who are determined to fight us to the death should all go to the imperial capital, this is the calm before the storm, and the real big war should be in their imperial capital. Long Ming said.

"Are they going to make a desperate bet, so close to the imperial capital, they will hold on to every inch of land, if they are lost, they will have no resources to fight a protracted war in the imperial capital. ”

"They won't fight a protracted war, on the contrary, they will fight quickly, I think their imperial capital must be a place with a lot of magic circle buildings and traps, and they want to wipe us out there. And their Emperor His Majesty thought very thoroughly, maybe let the defenders abandon the city and surrender is his meaning, he gathered the really powerful people to the imperial capital, with the most powerful force against us, and let the cities surrender to avoid the cities from being beaten by us, so that they can invisibly preserve the living force, if the emperor can defeat me, their surrendered cities will be easy to recover, because there is no battle, there is no loss of personnel and materials in each city. As soon as these surrendered defenders know that we have been defeated, they will return to the Empire as soon as possible, so that they can better defend themselves against foreign enemies. At that time, we will only be driven away. ”

"It turns out that the prince has already seen through everything, now that you already know that there will be a very difficult battle in Emperor Gongqiang, you should have thought of a siege strategy, right?"

"We don't have anything to say about what kind of formations and traps the Sonorous Empire will use, so we won't have any targeted siege strategies, we can only act at the opportunity, and at the same time do a good job of protection, minimize casualties, and wait for their ambush before we can have the strength to counterattack. But this kind of city-wide formation is generally very continuous, and we can only counterattack if we break the formation. Therefore, this siege requires a lot of defense capabilities from the soldiers, and as for how to break the formation, I have to study the war history of the Sonorous Empire with the magicians to see what formations they have and what flaws they can find. ”

"Lord Wang, the sonorous empire is known for its sound fighting spirit, their formation is nothing more than a sound type formation, we have encountered a sound wave array, in fact, it is nothing more than that, just plug your ears. ”

"It's not that simple, the Sound Wave Array is their lowest-level large array, and it doesn't have a dedicated sound magician. This time their imperial capital is different, it must be their strongest magic circle, it is not for nothing that the sonorous empire can stand on the continent for so many years, we can't underestimate the enemy. ”

"That's what the prince said, but if the enemy's weapon is sound magic or something, how can we defend it?"

"You guys practice martial arts first, and I still have to study the sound fighting spirit and magic. ”

Long Ming saw that the defenders of the Sonorous Empire no longer went to the front line of the battlefield after frequently surrendering, and he had to concentrate on studying the history books and sound magic to prepare for the attack on the Sonorous Imperial Capital.

Time flies quickly, as long as all the cities that the Celestial Dragon Army goes to raise their flags and surrender, the Sonorous Empire has almost been occupied by the Celestial Dragon Army.

However, the entire sonorous empire did not lose its life because of the war, because since they began to abandon the city and surrender, there was basically no substantive war.

The Tianlong Army is getting closer and closer to the imperial capital of the sonorous empire, but Long Ming's research on the sound array has not improved, and looking for books is only to understand some scratches, which does not help much for cracking the method.

Now that the morale of the Celestial Dragon Army is high, it is not advisable to stop the march, and it is necessary to use this momentum to break through the magic circle of the sonorous empire.

Ren Tianming came to the city wall of the imperial capital, he looked back and smiled, because he saw that the city was full of soldiers wearing armor, these were the dead soldiers who finally died, these people were rare, the number exceeded his expectations, with these people, he was confident to defeat the Tianlong Army.

As soon as the Celestial Dragon Army came, he would command the warriors to strike weapons, cooperate with his phantom fighting spirit, and make strange sounds, and then the magicians in the magic tower would spread the sound around.

The Celestial Dragon Army is here!

Ren Tianming smiled again, it seemed that he couldn't wait for a long time, this time he would let the Tianlong Army have no return!

He ordered the gates of the city to be opened, and the dead soldiers in the city came out to fight the Celestial Dragon Army to the death.

The sonorous army came out in an orderly manner, and immediately listed the formation after coming out.

"Drink, drink, drink!" they shouted a loud slogan and struck their weapons, which was really sonorous and inspiring.

The Tianlong Army led by Long Ming seemed to be a little suppressed by this momentum, and it was time for him to fight back.

Long Ming flew into the air, ready to release the magic forbidden spell.

But just as I was about to concentrate, I suddenly felt dizzy, nauseous and wanted to vomit.

Releasing the Magic Forbidden Spell required extreme mental concentration, and Long Ming was now sure that he must have been disturbed by the Sonorous Empire, and it was impossible for him to release the Magic Forbidden Spell.

The Sonorous Army had already rushed over, and the soldiers of the Celestial Dragon Army obviously had the same symptoms!

In this way, the Celestial Dragon Army had no backhand power, so it could only retreat.

Long Ming was very anxious, thinking that it was the attack of the sound magic array, so even if he couldn't release the magic forbidden spell, he had to use ordinary attack magic to blow up the magic tower of the sonorous imperial capital first.

A few blades of light sliced through the magic tower on the walls of the Sonorous Imperial Capital, but their symptoms did not retreat in the slightest.

"What's going on?" Wasn't it the attack of the magic array, Long Ming felt at a loss.

The symptoms of the soldiers of the Tianlong Army have become more serious, not only are they dizzy and swollen, but some people have become incontinent, delirious, and fainted to the ground!

Long Ming was shocked, it is very likely that the entire Tianlong Army will be wiped out like this, and none of them will survive!

Long Ming desperately wondered what kind of attack could make them like this.

The weapon of the sonorous empire is the sound, but now Long Ming can't hear any sound, only the shouts of the sonorous army and the sound of weapons beating.

How can this sound be insanity, the only explanation is the inaudible voice.

Long Ming racked his brains to think, the sound that people can hear is 20 hertz to 20,000 hertz, ultrasound waves of more than 20,000 hertz are not harmful to the human body, could it be that the sonorous empire uses infrasound?

Infrasound waves are similar to the natural frequency of human organs, which may resonate, causing organs to deform, displace, and even rupture, so as to achieve the purpose of killing.

But how could the Sonorous Empire have such high technology, this must not be a magic attack, infrasound waves can only be generated by physical means.

Long Ming thought about it, thinking that the secret weapon of the sonorous empire all along may be infrasound, that is, their phantom sound fighting energy, they may not understand what infrasound waves are, but their phantom sound fighting energy can indeed produce infrasound waves.

Although Long Ming is now basically sure that he was attacked by infrasound, he has no means of defense, and it is useless to block his ears, because the penetration of infrasonic waves is very strong, even if it is a city wall several meters thick, steel can't stop it.

Long Ming's only way now was to cut off the source of the infrasonic sound and stop their infrasonic attack.

But now he didn't know where the source of the voice was, and he couldn't release the magic forbidden spell, and he felt that his symptoms were getting worse and worse, and he couldn't support it anymore and fell down.

The soldiers of the Celestial Dragon Army can only be killed by the enemy now, and the situation is very critical.

"General Shantai, attack with crossbow arrows first and push the enemy back!" Long Ming returned to the ground and hurriedly ordered.

"Yes!" said Takeshi himself and fired his own crossbow arrows.

The crossbowman is in the back row, a little away from the source of the infrasonic sound, the symptoms are not so severe, and some crossbow arrows can still be fired.

"Lord Long Ming, are they a magic attack, why do I feel that I have no defensive ability at all?" Lang Hao also felt unprecedented powerlessness.

"It's a sonic attack, not magic, but it's harder than magic. ”

"Sonic attack? Where is the sound, why can't I hear it?"

"This kind of sound wave can't be heard by people, we have to find the source of the sound and cut it off. ”

"The source must be in the city, you can use the magic forbidden spell to blow up the city directly. ”

"It's possible to blow up the source, but now I'm so sick that I can't concentrate on casting the Forbidden Spell. ”

"I can't sit still here, so I have to go into the city to find the source of the sound. Lang Hao was ready to get up and fly into the city.

"No!" Long Ming grabbed him and said, "In your current state, you can't exert the strength of the ultimate warrior at all, and if you go in, you will probably be surrounded and killed by the masters inside, and then think of other ways." ”

"What else can be done?"

"Think about what can block out this sound, let's regain our strength, and then we can fight back. ”

"What's the most effective way to block sound?"

"What's that? By the way, only a vacuum can block the propagation of sound!" Long Ming finally remembered.

"What is a vacuum?"

"I can't explain this to you right now, I'll have to find a way to make a vacuum barrier. ”

Under the powerful crossbow arrow attack of the Sky Air Force, the sonorous army finally stopped, temporarily relieving the pressure on the soldiers in the front row.

However, the situation is not much better, because of the infrasonic attack, more and more of these warriors can not withstand it, even if the sonorous army does not kill them, they will not live long!

Vacuum! How do you make a vacuum?

Long Ming is thinking of a way, and now only he can save the Heavenly Dragon Army. He had almost forgotten that he was a space magician, and it shouldn't be difficult to create a vacuum.

Long Ming thought of a way, but he was also dizzy now, and he had to recover before he could concentrate on releasing the spatial magic.

So he took out an elixir, this elixir is very helpful for restoring physical strength, whether he can turn defeat into victory depends on this elixir.
