In the depths of the barren mountain, Zhao Xing and the three of them were trapped in the pitch-black field, and the interior was pitch black, but fortunately, Ezreal cast a lighting technique, which barely illuminated the internal area, Zhao Xing fixed his eyes, and the position of the three of them was in the center of the formation, and a huge skull pattern appeared strangely at the feet of the three people, although this formation was weird, but it did no harm to them, but only temporarily limited their range of activities.

"Brother Zhao, let's rush out. Ezreal asked in a deep voice with a solemn expression.

Zhao Xuan was silent for a moment, the thoughts in his mind were racing, and he was hesitating, when the voice outside came in again: "I'll count three times, if you don't disarm and surrender, you will only have a dead end!"

"Three!"

Zhao Xuan was still hesitating, it was not that he didn't dare to rush out, but he was worried that there would be an ambush outside, and once they rushed out, I was afraid that they would fall into the trap of the bone clan.

"Two!"

"Second brother, rush!" Yi Yin's Red Demon Sword was already clenched in his hand, and Ezreal was also a little eager to try.

"One!"

"Rush!" Zhao Xuan gave an order, and the three of them flashed, each took out their weapons, and rushed towards three different directions, and at the same time, the voice outside said sharply: "Release the arrow!"

Whoosh!

When he landed, he only heard the sound of arrows shooting into the field like an overwhelming sky, and the three people inside the field couldn't see the arrows outside at all, and could only rely on their keen hearing to determine the direction of the arrows.

Around the formation, there were about more than 400 bone clan people, and the rows of white skeletons were like tombstones, among the more than 400 skeletons, only five skeletons were spirit-level powerhouses, and the others were below the spirit level.

The five skeletons are divided into five directions to stand, the four skeletons are all third-order spirit level, one is the fifth order spirit level, their empty eye sockets are beating with a demonic soul fire, the strength of the bone clan is distinguished by the color of the soul fire, red, orange, yellow, green, blue and blue. The bone clan of the same strength relied on the depth of the soul fire to judge, the four third-order spirit level skeletons were light green soul fire beating in their eyes, and the fifth-order spirit level skeletons were dark green.

Bang bang!

After Zhao Xuan broke free, Yi Yin and the two scrambled to escape, and then met Zhao Xuan in the air, Zhao Xuan asked, "Are you all right?"

Before Yi Yin and the others could answer, the fifth-order spirit-level skeleton suddenly spoke, "Kill them!"

The words were still in the ears, and the skeletons of the five spirits or above jumped into the void, each took out a bone sword, and slashed towards Zhao Xing and the three of them, at the same time, the more than four hundred skeletons shot out white bone arrows, the speed of the arrows was fast, and the tips of the arrows flashed with a cold light, and in just an instant, the air area was filled with white bone arrows, sealing the back path of Zhao Xing and the three of them.

"Rui'er, those miscellaneous soldiers will be handed over to you, third brother, let's deal with this leader together!" At the last moment, Zhao Xing's whole body of fighting energy erupted, frantically poured into the spear, and violently waved the three-foot silver spear, drawing a brilliant silver-white half-moon-shaped spear arc, smashing all the oncoming white bone arrows, and the bone chips flew and crackled and fell in the forest, like a rain of bones, and at the same time forced back the five skeletons that were eager to step forward and kill the three of them.

"Arcane Shooting!"

Zhao Xuan won the time of an instant, Ezreal seized the opportunity, hurriedly dodged away from the void, flicked his fingers, hundreds of golden divine rays shot out, shooting in all directions, the more than four hundred skeletons standing in the forest were not good, and fled frantically towards the surroundings, but most of them failed to escape, and fell in the forest like a defeat, the skeleton exploded and flew, the soul fire was extinguished and dim, and most of them died in an instant.

"If you want to escape, no way!" Ezreal quickly caught up with the fleeing skeletons, killing them all without leaving a corner, which can be described as decisive and very crisp.

Regarding the death of his subordinates, the five spirit-level skeletons didn't seem to care, and they didn't go to stop Ezreal, but stared at Zhao Xing and Yi Yin fiercely, as long as they killed the two of them, Ezreal would naturally not be able to do it.

The fifth-order spirit-level skeleton glanced at the other four skeletons, and then attacked wildly, a pitch-black demon light condensed on the bone sword, and in a thousandth of an instant, the fifth-order spirit-level skeleton launched an attack on Zhao Xuan, and the other four third-order spirit-level bodies switched targets and attacked Yi Yin quickly!

"I'm going, so look up to me?" calmly looking at the oncoming four skeletons, Yi Yin held the Red Demon Sword tightly in his right hand, and waited for the attack of the four skeletons without moving.

"Let's go together!" one of the four skeletons suddenly roared, and then, the four skeletons turned into four white rays, surrounding Yi Yin in the middle, they were like four cheetahs that suddenly attacked, as fast as lightning, however, when their bone swords were about to split Yi Yin to pieces, they were surprised to find that Yi Yin's body gradually dissipated, and disappeared in the blink of an eye.

The four skeletons looked at each other, obviously not understanding the principle, just when they were in a daze, Yi Yin appeared behind one of the skeletons like a ghost, and then slashed out a sword, the power on the sword was huge, directly split the skeleton into two, and fell weakly on the dead leaves in the forest, and the soul fire beating in the eye socket flickered a few times, and then gradually extinguished, and a life whimpered.

An undead creature can only be slain if its soul fire is completely extinguished.

"Avenge us!" The other two skeletons were furious and trembling with rage when they realized that their companion had died, and then they did something that surprised Yi Yin - they committed suicide!

The two skeletons suddenly stripped off the light green soul fire in their eye sockets, and then fell from the void paralyzedly, and handed it to the remaining skeleton, and the remaining skeleton stuffed the obtained soul fire into its own eye sockets, and at that time, the soul fire in the skeleton's eye socket was full of light, directly changing from light green to dark green, and its strength was promoted to a fourth-order spirit level!

"What a wicked exercise!" Yi Yin was stunned in surprise, but he was not afraid, because fear will only make people nervous, and calmness can keep people awake.

"Quack...... Come on!" The eyes of the remaining skeleton shot out a penetrating fierce light, and the bone sword slashed forward, and a pitch-black sword light the size of a hundred zhang came out of his hand, bringing a burst of sound of breaking the sky, and the sound was terrible towards the direction where Yi Yin was.

"You want my life, you underestimate me too much!" Yi Yin slashed out with a sword, and a white sword light the size of a hundred zhang flew out, and with lightning speed, the two sword rays collided violently.

Splatter!

At the junction, the space was broken, the towering ancient trees nearby were broken from it, the branches and leaves trembled, and they fell down one after another, the sound of clicking and clicking was endless, and the gusts of energy swept in, and the vegetation rose from the ground and was rolled into pieces, fortunately, there were no birds of prey in this barren mountain, otherwise, the battle between the two would kill many weak beasts inadvertently.

"Can you even fight me?" the flame flickered in the skeleton's eyes, and there was a hint of surprise in his words.

"Hehe, if you're afraid, you can kneel down and beg for mercy immediately, and I may be able to spare you from dying. Yi Yin said coldly.

"Scared?" the skeleton also sneered, "From birth to now, except for the patriarch, I have never been afraid of anyone!"

Yi Yin didn't reply, but probed the surrounding situation, Zhao Xing's fifth-order spirit level skeleton's battle had already left the area where Yi Yin was fighting, Yi Yin could only occasionally hear a few explosions from the deeper part of the mountain forest, Ezreal chased those fleeing skeletons, and they were gone, I don't know if he was safe.

"Looks like we're going to have to get rid of your annoying guy quickly. Yi Yin's eyes were cold, and he thought in his heart, and then sneered, his whole body's momentum soared, and his body turned into a white rainbow, and in the blink of an eye, he had already come to the top of the skeleton's head, and shouted softly: "Crazy fire and sword roar!"

Before the words fell, Yi Yin used the technique of birth fire, and condensed into fire when he landed, and the scorching flames spread all over the sword body, and the fire was monstrous, condensing into a flame sword of about three hundred zhang in size on the sword body, compared to the sword just now, the attack power was increased by three times!

"Black Bone Ruthless Sword!"

Not to be outdone, the bone sword secreted a dark mist like ink, swirling around the miserable white sword body, the mist was dark and gloomy, from which came all kinds of men, women and children screamed, the voice was tragic and sad, as if from under the nine shadows, making people's hairs rise, these mist gathered into a ball, burst out from the tip of the sword, and the flame sword attacked.

Now that it has been promoted to the fourth-order spirit level, of course it will not be afraid of a third-order spirit level attack, but the attack power that Yi Yin has exerted is far beyond the scope of the third-order spirit level, even if it is an ordinary fourth-order spirit level, it is also difficult to harden the next. This made it a little more worried when it made a move, and it almost used all its strength to resist, for fear that it would not be able to resist Yi Yin's attack.

If it has already been promoted to the fourth-order spirit level, and wants to take over this sword, although it will take some strength, but after all, it will be able to take it unharmed, but unfortunately, it is relying on the strength of its companions to improve its own body, the method is evil, the promotion speed is fast but the foundation is seriously unstable, with the passage of time, its strength will be extremely unstable, and it must go through a long period of adjustment before it can be completely absorbed, so as to be truly promoted.

It was too late, and the fog and mist had already begun to entangle, and as soon as the two came into contact, they hissed, and the two did not give in to each other, devouring each other and annihilating each other, depending on the situation, they were evenly matched!

"Burn it for me!"

Yi Yin snorted coldly, and quickly urged the fighting qi in his body, all of which were injected into the body of the Red Demon Sword, and the flames were full of momentum, and in an instant, the black mist was burned into nothingness, and the black mist retreated, and the momentum immediately dimmed.

"This ...... How is this possible?" It seems that it does not believe that a third-order spirit level can exert such ferocious combat power, the skeleton obviously does not have enough physical strength, but it still delusions that it can defeat Yi Yin, it uses all its strength, desperate, and is ready to fight with Yi Yin.

After the skeleton's dying struggle, the black mist began to resist, however, it only resisted for a moment, and in the end it couldn't withstand Yi Yin's flame attack, the skeleton was disheartened, retreated, and his body flashed, picking a hidden direction, intending to escape.

"Hmph, human, you're lucky this time, I'll let you go first, and I'll settle accounts with you next time!" After saying that, the skeleton burst open, and the entire torso shattered, leaving only a skull mixed with two soul fires flying out and breaking into the dense vegetation nearby.

"Hehe, do you think you can get away?" Yi Yin's divine thought leaned out, immediately locked the position of the head, and then sneered: "Goodbye!"

Immediately afterward, the Red Devil Sword slashed through an arc of death, nailing down towards a certain area of vegetation in the forest with incomparable precision, and a deafening howl was heard, and the head was smashed by the Red Devil Sword, completely lifeless.

Retracting the Red Demon Sword, Yi Yinshennian leaned out and searched for Zhao Xing's location, his figure flashed upward, swaying up like a big bird, and swept towards Zhao Xing's location......
