Yang Ning stared at the skull, thoughtfully, and soon a spiritual power probed into the skull, running Ling Tiandu, and took the initiative to rush towards this filtered immortal aura, but the moment Yang Ning's aura approached, this wisp of aura disappeared as if it did not exist.

"How so?" Yang Ning asked.

Yao Xinji shook his head and gave the answer: "It's useless, this kind of breath, don't say if you and I can contact it now, even if it has been dabbled, but if you want to plunder, it is almost impossible." ”

"Why?" This was the first time since Yang Ning had cultivated Ling Tiandu, and he was very unconvinced.

"This kind of aura is generally cultivated by the cultivator himself, and it can be said that it is related to the cultivator's fate, so unless the cultivator himself agrees, it is difficult to plunder, I remember......"

"What do you remember?" Yang Ning hurriedly asked, after all, this is related to immortals, even Yang Ning has to be curious.

"I remember that Lao Dao once said that unless someone's cultivation is stronger than that of the dead, with Ling Tian's strength, they can plunder." Yao Xinji stared at the skull in his hand, and he was also a little unwilling.

When Yang Ning heard this, he could only give up, although Yang Ning didn't know what the specific cultivation of the old way was, but one thing was certain, it was definitely beyond killing the Sword Saint, otherwise he wouldn't have let Ximen Kill take the initiative to go to the Firmament Realm that day.

"Hey......" Yang Ning sighed helplessly.

But Yao Xinji put the skull away.

"It's useless, why are you still putting it away?" Yang Ning said.

Yao Xinji said casually: "How can it be useless, after all, this is an immortal skull, even if it can't be absorbed, but it can be used to smash people......" Yao Xinji smiled sinisterly, looked around, the fog around was not very thick, and he didn't find Lin Jian and Xuanyuan Tingxue.

"It seems that the two of them have already gone deeper, let's hurry up, don't worry, let Xiaolinzi get ......" Yao Xinji led the way and walked towards the depths.

Yang Ning was even more speechless, when he saw Yao Xinji, there was still a sense of justice in this person, and now he ...... It's wrong......

He actually wants to smash people with an immortal skull......

Yang Ning wanted to say it very much, let the dead be great, but when the words came to his mouth, he couldn't say it, pulling Huan Ling, his eyes kept glancing around on the ground, as if he was looking for something.

However, it seems that the skulls like the one just now are also very rare, and the three of them have seen a lot of white bones as they have traveled for miles, but there is not a single one that is as crystal clear as the skull.

"It seems that the owner of that skull was definitely the strongest one when he was alive......" Yang Ning felt a little lost inexplicably.

The four fields are vast, it seems that the space of this ancient battlefield is infinite, as the three of them go deeper, there is no thick fog around to block the view, only the sound of shouting and killing that is constantly floating around the sky is echoing.

The sky dome gradually began to change color, and it seemed to have a slight red light, although it was very faint, but it gave people a sense of oppression, because no matter how you look at it, this red light feels like blood.

Whew......

The wind is gusting.

......

Yang Ning inexplicably felt a palpitation, and Huan Ling also subconsciously clenched Yang Ning's hand.

"Ling'er ......"

"Brother Ning, how do I feel, it seems that something is watching us......" Huan Ling, as an ethereal immortal, has a sense of the environment above Yang Ning, and as the yin wind hit, he lightly opened his lips, and his face became a little unnatural.

Yao Xinji seemed to feel something, directly picked up the skull, and then smashed towards the flat-looking void in front of him.

Touch!

Thundered......

It seems that the ban has been triggered, and the three of them only feel that the scene around them has changed greatly, and the originally barren ground has appeared with white bones, only residues remain, and even some bones have scars on them.

"Not good!" Yao Xinji hurriedly ignited the sigil in his hand, and his figure disappeared in place, but the next moment, Yao Xinji's figure appeared in the place where he disappeared.

"It's blocked, we seem to have entered a realm......" Yao Xinji had already come to a conclusion, and his eyes kept looking around.

Yang Ning also sensed that something was wrong, especially in the surrounding air, there was an extra barren aura, and his spiritual power was suppressed in his body, and he couldn't detect it at all.

"Brother Ning......" Huan Ling shouted, and between his hands, the seal appeared, attacking Yang Ning's back.

Yang Ning also hurriedly turned around, only to see a skeleton-like image opening its mouth towards him.

Thundered......

With the image of the Ring Spirit's attack, there was a terrifying roar, and the image of the skeleton disappeared without a trace.

"Be on guard." Yang Ning had the sword in his hand, and his body was spinning in place, constantly guarding the surroundings.

"Yao Xinji, be careful!" In just an instant, the image of the skeleton shattered by the Huan Spirit appeared above Yao Xinji's head.

Yang Ning's sword came out with a red glow, and it was a sword directly towards the image.

Thundered......

The skull image dissipated again.

Yao Xinzhen had palpitations, and hurriedly picked up the skull that he had just thrown out, holding the skull in his hand, and the three of them leaned back together in a triangle.

"What is this?" Yang Ning asked.

"I don't know!" But Yao Xinji still said with certainty: "We should have broken into a remnant domain, if I guessed correctly, this skeleton image should be his obsession before his death, and it will be integrated with the remnant domain, and then trap the intruder, and then kill him." ”

"No, we have to break the domain quickly, otherwise we are in danger." Yao Xinji said, the talisman in his hand burned, and instantly turned into a sharp arrow, shooting towards the dull-looking void.

Thundered......

The sharp arrow exploded, and layers of ripples appeared in the air.

"Remnant Barrier!" Yang Ning stared at the place where the ripples were generated and exclaimed.

Whew......

"Overhead!" Huan Lingjiao shouted, and slammed up with a palm, shattering the skeleton image again.

Yang Ning didn't hesitate, and directly started with a sword, and the blood-red sword light was on the barrier of the remnant domain.

Thundered......

Yang Ning's figure regressed, and he was shocked by the power of the remnant domain

"Brother Ning......" Huan Ling hurriedly supported Yang Ning.

"Be careful!" Yao Xinji burned a sigil and shot a sharp arrow, shattering the image of the skeleton that wanted to take advantage of the void again.

Yang Ning only felt that his qi and blood were surging, and the backlash of the remnant domain made Yang Ning extremely uncomfortable.

"No, if this continues, we will be dragged down by the obsession of this remnant domain until we die." Yao Xinji quickly understood why there were so many dry bones under his feet, he must have been tortured by the remnants of the domain and dragged to death.

"But, can we break through this remnant?" Yang Ning suppressed the shock in his body and stared at the void.

"It must be broken, otherwise we will really explain it here......" Yao Xinji said, his eyes were solemn, and there was an extra red rune in his hand, very reluctant and distressed.

Although Yang Ning couldn't see anything special about this red rune, it must be different from the yellow rune that Yao Xinji had taken out in the past, otherwise Yao Xinji would not have that distressed expression.

"Are you so, okay?" Yang Ning asked.

"If you can't do it, you have to do it, otherwise we will only be like these dry bones......" Yao Xinji stared at the red rune in his hand, very reluctant.

"Would you like to help?" Yang Ning asked, and there was a roar above his head again, it was Huan Ling who had once again shattered the skeleton image.

"Yes, definitely, if the remnant domain is broken later, you will be responsible for taking me out." Yao Xinji said, still looking at the red rune, it was very painful.

"As for it?" Although Yang Ning didn't know how precious this red rune was, he was speechless when he looked at Yao Xinji's distressed appearance.

"As for it?" Yao Xinji shouted: "This talisman is a life talisman given to me by that old guy, I have endured so many years of grievances, that old guy only gave me three, do you say it is precious?" ”

Yang Ning didn't speak.

"Okay, if this rune is ignited, the remnant domain will definitely be broken, but if you want to ignite this rune, the price is a bit big, so please take me out when the time comes." Yao Xinji said, a drop of blood red appeared between his fingers, dripping towards the red rune.

Yang Ning clearly felt that Yao Xinji's breath was chaotic with the dripping of this drop of essence blood.

"Remember, bring me my skull." Yao Xinji didn't forget to explain, and then in the palm of his hand, the soul fire burned, igniting the red rune.

The burning was fast, but it was at this interval that the skeleton image had already sneaked up on the three of them no less than ten times, but each time it was stopped by Yang Ning and Huan Ling, and then shattered.

Between Yao Xinji's palms, as the red rune gradually turned into ashes, a blood-red arrow appeared, first an arrow, then an arrow shaft, and then a cluster of arrows......

"Hurry!" A roar seemed to take away all of Yao Xinji's strength, and Yao Xinji himself completely softened with this roar.

The sharp arrows shuttled, like lightning, turning into a blood-red light, shooting straight at the remnant barrier.

Yang Ning also pulled up Yao Xinji's figure, opened the way with the killing sword, and walked side by side with Huan Ling, following the trajectory of the sharp arrow's movement, and flew up.

Thundered......

Thundered......

The skeleton image is shattered once again by the Globe Spirit.

At the same time, above the barrier of the remnant domain, countless ripples were born, scattering in all directions.

The blood-red arrow was like an indestructible spear, piercing the remnant barrier.

Although Yang Ning doesn't believe in Yao Xinji's strength, but for that old way, Yang Ning believes in a hundred things, and if the old way makes a move, it will be a high-quality product.

With the sharp arrow to break through the remnant domain, Yang Ning's killing sword point was on the remnant domain that already had a rift, but Yang Ning didn't dare to be careless, after all, this was the power of the domain realm, Yang Ning knew that he had to go all out, otherwise Yao Xinji's efforts would be in vain.

With the blessing of the three sword embryos, Yang Ning's body directly displayed the power of the Extreme Realm, and in the sword bones, a powerful aura was constantly exuded.

"Open the sky with a sword!" Yang Ning roared, and the sword fell on the remnant domain.

Thundered......

The remnants shattered.

The surrounding desolation dissipated, the dry bones below sank, and the breath of the four wilds appeared again.

"Coming out?" Yang Ning was really scared, although he didn't know what the scene would be like when he was devoured by the skeleton image, but Yang Ning was sure that those dry bones would definitely be their fate in the near future.

On Huan Lingqiao's face, beads of sweat rolled down.

"Ling'er." Yang Ning called out.

"Brother Ning." Huan Ling agreed, his voice trembling a little.

"Do you regret it?" Yang Ning asked.

Huan Ling's face was shocked, but it was replaced by a tenacity, shook his head, and said, "I don't regret it, as long as I can be with Brother Ning, I won't regret it." ”

An inopportune voice rang out.

"Hey, I'm still here......" A weak voice sounded on Yang Ning's shoulder, but soon, he screamed again: "What's on your stomach, it's on me......"

Yang Ning's face turned red, and he hurriedly put Yao Xinji down.

"I said brother, is it appropriate for you to take my life to pick up a girl?" Yao Xinji sighed and emphasized again: "Is it appropriate?" ”

"Is it all right?" Yang Ning could only ask stubbornly.

"I can't die, a drop of blood, a red talisman......" Yao Xinji's heart was dripping blood.

At this moment, a skull suddenly fell from the sky.

"Huh?" Yao Xinji stared at the skull, it seemed to be a little familiar, but it didn't feel like the skull he was holding before, his gaze moved slowly to Yang Ning.
