This is a special whistle that concentrates sound waves in a straight line to propagate, like a laser. In this way, the energy of the sound wave will not be dissipated, and the sound can be very penetrating so that it can travel farther.

According to research, the sound of such a whistle can be transmitted to a distance of five kilometers with sufficient energy.

Usually, such whistles are used for emergency SOS in the jungle. Because of the shielding of the mysterious energy in the jungle, ordinary wireless communication tools cannot receive signals at all. However, the jungle is an extremely dangerous place, and once a team on a mission encounters a high-level alien beast that they can't solve, they will blow such a whistle to call for help. In this way, mercenaries and guards within a radius of at least three kilometers will know that a team is in trouble and will follow the direction from which the sound came to know when they hear the whistle.

This is supposed to be an emergency tool. In principle, all mercenaries or guards who hear this whistle must assemble in the direction from which the whistle came, and cannot avoid it, which is a mandatory rule written into federal law.

But at this moment, in this uninhabited jungle, the whistle appeared, and it was obviously impossible for someone to be in trouble. At this time, this kind of whistle can only be a situation - the enemy is in sight!

Ling Bing's divine sense jerked in the direction where the whistle came from. Not only did Ling Bing do this, but all the abilities on the scene also released their spiritual power and probed in the direction of the whistle.

The whistle continued to sound, from far and near, rapidly approaching in the direction where Ling Bing and the others were.

The distance of five kilometers is not a long time, but it is not a short time, and for a high-level ability who can fly in the air, it is only a matter of ten minutes.

Soon, a black-robed man whose whole body was tightly wrapped in a black robe landed in front of Ling Bing and the others.

The black-robed man blocked his face so tightly that he couldn't see his appearance at all, but he didn't hide anything about his own rank.

This black-robed man was a ninth-order martial artist.

The compelling aura, the blood-colored martial energy, was like Chongyue pressing down, making the eighth-order elites brought by Ling Bing feel that their breath was stagnant, and their chests were so tight. Naturally, his face flushed. However, everyone stubbornly straightened their waists, gritted their teeth and urged their own energy shields and elemental shields, and resisted the coercion from the black-robed man.

The most unbearable is Shi Xuan. He only has a seventh-order, and he is a seventh-order who has been forcibly promoted by external forces. Under the pressure of the black-robed man's aura, he involuntarily let out a muffled snort, his legs weakened, his knees fell to the ground, and the whole person fell to the ground.

The second is Feng Tianfang, Feng Tianfang is also a seventh order, under the deliberate coercion of the black-robed man, his body involuntarily shook several times, his legs trembled, and he almost knelt to the ground following in Shi Xuan's footsteps. But Feng Tianfang held his breath and stood upright, even though his body was like grass in the cold wind, shivering, but he didn't kneel, and he didn't even make a sound.

Ling Bing waved his hands, and a spiritual shield blocked everyone's face, blocking the coercion from the black-robed man.

Yang Ye snorted even more coldly, and his spiritual power condensed, and a force of spiritual power that was purer and more massive than the black-robed man crashed into the black-robed man.

"Poof~"

The black-robed man was hit by Yang Ye's spiritual power, and his chest was hit hard, and a mouthful of blood spit out violently. The coercion is also self-defeating, and it is scattered.

Everyone felt lighter, and their bodies were free again.

Shi Xuan, who involuntarily knelt on the ground, was finally able to raise his head at this time. But when he found that he was the only one at the scene who was forced to kneel on the ground, and everyone else, including Feng Tianfang, who was also a seventh order like him, was standing well, his face couldn't help but turn red, and his eyes quickly flashed a trace of resentment.

"Hehehe~~"

The black-robed man, who spat out a breath of blood, let out a gloomy sneer. He casually raised his hand and wiped the corner of his mouth casually, and poured a bottle of liquid into his mouth.

"I have admired the name for a long time, His Royal Highness Yang Ye, it is really so majestic!

"Get off the horse, this seems to be your Highness's handiwork, right? Before anyone arrives, the coercion arrives first, is this trying to scare the children we brought?" Yang Ye was expressionless and glared coldly at the black-robed man.

"Oh, did I release coercion? Oh, I'm sorry, I'm sorry, it's a habit, I didn't notice that you also brought a child below the ninth order, it's really an accident!" the black-robed man laughed ill-willedly.

All the elites glared at the black-robed man. With so many of them standing here, he actually said that he hadn't noticed? How long were his eyes, obviously he didn't pay attention to them as Eighth-Order Awakened Beings at all!

"It's you, it's you, give me back the fire, give me back the fire!" Shi Xuan suddenly rushed out from behind the crowd and roared at the black-robed man.

Shi Xuan's eyes widened, he was emotional, and the muscles on his face twitched violently, causing the wound that had already scabbed to collapse again, oozing a wisp of blood.

But Yang Ye frowned when he heard this, and his heart suddenly became extremely uncomfortable.

Although Shi Xuan was emotional, what he kept screaming was asking the black-robed man to return the Fire Lady to him, not to return everyone in the Fire Thorn Clan. Could it be that in his heart, except for the Fire Lady, none of the other people in their Fire Thorn Clan are important?

"...... you?" the black-robed man looked at Shi Xuan, who rushed to Yang Ye, and couldn't see any expression on his face covered by the black robe, "That vice captain of the Fire Thorn Squad?" Hehe, yes, yes, you really did a good job in completing this mission." I didn't expect you to actually bring Hua Jiujiu over!Hehehehe, just rush you to complete the task perfectly this time, and we will definitely return your fire to you. ”

There was an indescribable contempt in the words of the black-robed man, although they were words of appreciation, which made people sound, but how uncomfortable they sounded!

Especially when the black-robed man followed Shi Xuan's words and promised to return the Fire Lady to him, but did not say that he would return the rest of the Fire Thorn Clan's team to him as well, Feng Tianfang and the ten elites couldn't help but have a trace of doubt in their eyes when they looked at Shi Xuan.

Only Yang Ye and Ling Bing still looked at each other without squinting, as if they didn't understand the meaning of the black-robed man's words.

Everyone's gaze at Shi Xuan was so obvious, Shi Xuan naturally immediately felt the malice brought by the black-robed man's words.

"You have promised, as long as His Highness Jiujiu can come forward, you will release everyone in our Fire Thorn Clan. Not just Huo'er, but everyone else on our team. You can't go back on your word!" Shi Xuan's face was in a hurry, and as soon as he was excited, the muscles on his face twitched even more, and the wound finally cracked open again, and blood gushed out.

"Get out!"

The black-clothed man's voice sank, and he suddenly shouted at Shi Xuan. Negotiate the conditions with them, and it depends on whether he has the qualifications. A small seventh-order, if it weren't for the fact that the Fire Lady in their team had such a slight relationship with Hua Jiujiu, which was worth using, how could he, an ordinary person with mediocre qualifications, be qualified to stand in front of him now?

Shi Xuan's face suddenly turned pale, and his heart suddenly sank to the bottom.

What he feared the most in his heart still happened, the only thing he could be used by others had been used, which meant that his value had been reduced to the minimum. So now he is insignificant?
