The White Bone Skeleton didn't have as many concerns as Xu Mu.

After taking a step back, counteracting the power of the flying sword, he controlled the body that only had the skeleton frame left, and pounced again.

A never-ending posture.

"It's really difficult!" In the face of the fierce pursuit of the white bone skeleton, Xu Mu also rose into a burst of anger, and his eyes narrowed into a dangerous arc.

Consciousness moved.

"Boom!" the flying sword took off again.

The sharp flying sword burst out with brilliant sword light, and once again fought with the white bone skeleton.

Fortunately, the vines that were scorched by the mysterious flames of the white bone skeleton were transformed by Xu Mu's spiritual power, and they could still burn for a while. Illuminating the area allows Xu Mu to clearly capture the movements of the bone skeleton.

Otherwise, with its swift speed, acting in this darkness, Xu Mu is really not good to fight against.

"The white bone skeleton is newborn, and the wisdom should not be high!"

After a long battle, Xu Mu had some understanding of the White Bone Skeleton.

Feeling that the time was almost up, he immediately controlled the flying sword with all his strength and slashed the strongest blow.

The sharp sword surged suddenly, slashing towards the white bone skeleton.

It seemed to feel the power of this sword, and the ghostly fire in the skeleton's eye socket rose, and the fist of Sensen's white bones was covered with a layer of dark blue flames.

It's going to be a tough fight with the flying sword.

"Boom!" the fist collided with the flying sword.

The flying sword was once again knocked away by the bone skeleton.

The white bone skeleton also had a brief pause in its body because of the punch.

"Chance!"

In this instant, Xu Mu caught its mistake, his eyes lit up, and he played again.

Three vines, which were more than twice as thick as before, quietly drilled out from behind the white bone skeleton, directly binding it that could not be touched by it.

The white bone skeleton was unexpected, and was wrapped into a rice dumpling by vines.

"Die!" Such a good opportunity, how could Xu Mu miss it, after a burst of shouts.

At the front end of the vine, a gorgeous flower bud grew out rapidly under the urging of Xu Mu's spiritual power.

Even if it is a cultivator of the Sixth Heaven of Imperial Qi, if he bears this blow head-on, he will also be injured.

However, the strength of the White Bone Skeleton is not bad, although it is the Fifth Heaven of Imperial Qi, but the cultivators whose realm is above it will also feel tricky to fight against it.

The next moment, something happened that made Xu Mu's heart tremble.

The white bone skeleton was actually bound by Xu Mu's three vines blessed with the power of the spiritual root, and its whole body ignited with sky-high blue flames.

Although the flames exuded a breathtaking coldness, the three vines withered at a speed visible to the naked eye under the scorching heat of this cold fire.

I'm afraid that before that spiritual power bud blooms, the technique of moving flowers and building blocks will have to be broken by the white bone skeleton.

This was the first time Xu Mu had encountered an opponent of the same level as himself, and he had to break free from the shackles of the wood technique so quickly.

He is a Xuan-level spiritual root, and in the face of a yellow-level spiritual root, he is generally crushed.

This is the first time he has encountered an opponent of the same rank who is fighting against him, and he is still a skeleton.

"This white bone skeleton, when he was still a cultivator in front of him, the awakened spiritual root is definitely related to this kind of ghost fire. ”

The scene that appeared in front of him made Xu Mu so shocked that he had to make such an inference, and he had another idea in his mind.

"The grade of that kind of ghost fire spirit root should not be low, among the yellow-level spirit roots, they are all top-level, or in other words, in front of him, he is the owner of the Xuan-level spirit root. ”

Thinking about it, Xu Mu's heart sank.

Immediately, the spiritual power in the body boiled, and the speed at which the bud opened was pushed to the limit.

He wanted to bloom the spiritual power flower before the bone skeleton broke free from the vines.

Otherwise, everything you have done before will be in vain.

Outside the mound.

It's been more than half a day now.

The Gate of Returning to the Ruins still did not disappear after the twenty disciples entered the Returning Ruins Tomb.

Under the maintenance of the top spirit bead magic weapon, it exudes a brilliant golden light.

The head of the Guiyuan Sect, Han Zong, faced the gate of Guiru, with an elegant face, his brows were still tightly locked.

It seems that he is still worried about Xu Mu's entry into the ruin mound.

"I said, senior brother, why do you always pull a face, everyone has entered, you are just adding to your troubles. ”

Zhu Xi held the wine gourd in his hand, took a sip alone, showed a comfortable smile, and then looked at Han Zong and said, "Xu Mu is a Xuan-level spiritual root, maybe, he really let him bring out the inheritance of the Burning Heaven Ancestor." ”

"Moreover, in the four thousand years since I returned to the Yuan Sect, I have almost no experience of the Xuan-level spiritual root falling in the Guiru Tomb. Don't worry about it. ”

"Senior Brother Zhu, it's not that you haven't heard of it, but you haven't heard of it. Jiang surnamed Daogu did not squint, and what she said was like a basin of cold water splashed down, and said leisurely:

"Have you ever heard that three hundred years ago, there was a Xuan-level spiritual root disciple in my Guiyuan Sect, named Dou Xi. ”

"When his Nine Ghost Fire Spirit Roots awakened, they burned half of the mountain range of the Outer Gate. This fire is extremely cold, the water is splashing, the fire is fierce, the end is weird, and it will not be extinguished for three days and three nights!"

"In the end, it was a strong person in the Dharma Body Realm of the sect who made a move to destroy it. ”

"And this Dou Xi, three hundred years ago, he entered the Guiru Tomb and never came out again!"

Hearing the clear tone of the Daogu surnamed Jiang, the fat Taoist smiled.

In fact, he knew about it, but he didn't react for a while.

"Alas!" Hearing the conversation between Senior Sister Jiang and Senior Brother Zhu in his ears, Master Han became more and more melancholy, and sighed heavily.

Although Xu Mu is a Xuan-level spiritual root, the probability of obtaining the inheritance of the Burning Heaven Ancestor is much higher than that of the disciples of the yellow-level spiritual root, but if he falls into it, it will be an immeasurable loss for the entire Guiyuan Sect.

If he also fell into it, then he would be the second Xuan-level spiritual root disciple in the history of the Guiyuan Sect to fall into it.

As soon as he thought of this, he was upset.

"Dou Xi!" Next to the three of them, the Changming Daoist, who had been silent, read out the name of the fallen Xuan-level spiritual root disciple.

......

"Give me a !!" Xu Mu tried his best, and with a burst of shouts, he finally detonated the flower buds.

Under the scorching of that blue flame, most of Xu Mu's vines withered.

Moreover, the withering of the vines seriously affected the speed at which the buds bloomed, and the white bone skeleton was about to break free from the shackles of the vines.

Xu Mu finally took a step ahead of it and bloomed the spiritual power buds.

"Boom!" The furious spiritual power instantly submerged the white bone skeleton.

The mountain shook, and the light emitted by the explosion of spiritual power illuminated the entire low mountain in an instant.

For a while, it was as bright as day.

Xu Mu himself, one step earlier, got out of the explosion range of the shifting blocks.

But his expression was solemn and he still did not let his guard down.

That skeleton had always given him a sense of danger, and the strange flames could actually burn the vines that had blessed him with the power of the multicolored spirit tree.

With his tongue stretched out, he gently licked it on his somewhat dry lips, and Xu Mu's eyes stared at the center of the spiritual power explosion without blinking.

He had prepared for the worst.

"If you don't die, I'll give you a whip!"

After thinking about it, Xu Mu took out the Shadow Whip from the sea of qi, and gently held the palm of his hand on the handle of the Shadow Whip, ready to whip out at any time.

After a few moments, the explosion calmed down.

The energy bombardment of the moving bricks dissipated.

The light produced also disappeared, and darkness was ushered in again on the low mountain.

Xu Mu's eyes were fixed on the deep pit that exploded after the energy bud exploded.

Suddenly, his pupils shrank, and Xu Mu didn't see the white bone skeleton.

If it dies under its own grafting, it will be able to leave a few bones behind, and with the hardness of the bones of the white bone skeleton, it is impossible to blow it up to pieces.

Xu Mu had no doubt about this.

However, he didn't find any bones of the white skeleton.

"Not good!"

Xu Mu squeaked in his heart, became alert, and then stomped under his feet and retreated frantically.

Almost at the moment when his figure retreated, a white bone skeleton wrapped in dark blue flames burst out of the ground from where he had just stood.

The force of the skyrocketing attack was incomparably huge, and it actually rose several feet from the ground.

Although it had already pulled some distance from the white bone skeleton, Xu Mu could still feel the flames burning slowly above its body, and the deep cold temperature emitted.

Where is this flame, it is even colder than ice.

His gaze swept over the body of the white bone skeleton, and Xu Mu's heart sank again.

Wrapped in that strange blue flame, the white bone skeleton was incredibly unscathed under the condition of hard resistance to grafting.

Now it seems that the strength of this white bone skeleton is probably above Du Tao.

"There's no way, you have to work hard!" Looking down and glancing at the shadow whip in his hand, Xu Mu shook his head helplessly, and put it into the sea of qi with his backhand.

With the defense power of the white bone skeleton, the effect of the shadow whip is probably not large, and it is difficult to kill the white bone skeleton with one blow, but it will consume half of its spiritual power.

At that time, his spiritual power was exhausted, and he was completely a lamb to the slaughter in front of the white bone skeleton.

The shadow whip disappeared, Xu Mu had already made a decision, his face showed a resolute expression, and he slowly read it word by word: "Fa! Xiang! Qian! Kun!"

"Boom!" fell with four words.

In Xu Mu's body, in the center of the vortex of Qi Sea spiritual power, the multicolored spirit tree burst out with extremely brilliant multicolored streamers.

Colorful light spread all over his limbs in an instant.

His entire body, bones, meridians, and muscles, at this moment, were covered with colorful colors.

Even his long black hair faintly revealed a colorful glow.

Then, the mysterious and unpredictable appearance of the Colorful Spirit Tree quietly appeared behind Xu Mu.

The multicolored spirit tree more than three feet tall stands in this space.

Xu Mu was covered in colorful light, standing under the colorful spirit tree, his momentum continued to rise, and his majesty was terrifying.

At this moment, he felt as if he had an inexhaustible strength.

It's as if a punch can pierce the sky.

"Roar!" The pleasure of the continuous outpouring of strength in his body made Xu Mu can't help but look up to the sky and roar, and a sound wave, with his roar, shook all directions.
