The calm surface of the water suddenly cracked like a mirror, and countless cracks appeared, and then, a ball of bony light flew out of the crack and floated in the air.

That ball of bone light, the outer layer was covered with a transparent skin, and when you looked closely, it was actually the cortical layer of the Swallowing Yuan Holy Beast.

It's just that the cortical layer, which is six or seven feet long, has now become a fist-sized mass of transparent skin, which is really a bit incredible.

The bone light in the skin bag was naturally the rune bone sword released by Wu Yan before.

Wu Yan raised his hand and made a move, and the bone light reached his hand.

When the light flickered, the skin sac fell off and returned into a transparent cortical layer six or seven zhang long, but it was directly wrapped around his arm by Wu Yan, who had been prepared for a long time.

The Rune Bone Sword then appeared in front of Wu Yan, but it was quite different from when it was released before.

Its length was still about three inches, but at the end of the hilt of the bone sword, there was an extra blood-colored ball of light the size of a fingernail.

At first glance, there was nothing unusual about this blood-colored ball of light, but through the rune bone sword, Wu Yan could clearly sense the surging essence and blood essence aura emanating from the ball of light.

Who would have thought that this blood-colored ball of light the size of a small fingernail would actually contain a essence and blood essence comparable to that of a powerhouse at the level of the Great Immortal Venerable?

Wu Yan's face was filled with surprise and joy.

This was the first time he had used the Rune Bone Sword, but he didn't expect the effect to be surprisingly good.

This runic bone sword can not only extract the essence of the immortals, but also the origin of the Swallowing Immortal Beast.

Moreover, while extracting the essence, it even quenched this essence, so that these essences were even more easily absorbed by Wu Yan.

After carefully sensing for a moment, Wu Yan slightly compared his eyes.

At this moment, a heart-shaped ball of light that emitted blood-colored holy light suddenly flew out of his body and froze next to the Rune Bone Sword.

This heart-shaped blood-colored ball of light, only the size of a fist, looked like a heart, but when you looked closely, it looked like a seed.

There were nine strange orifices on it, and each of them emitted a different strange energy fluctuation.

This heart-shaped blood-colored ball of light is Wu Yan's life talisman seal.

As soon as the Talisman Seal appeared, there was a strange fluctuation in the surrounding Guiyuan Sea.

With the Guiyuan ship that Wu Yan was standing on as the central point, the sea below actually rippled in a circle of strange ripples. If someone sees this, it will definitely shock everyone!

You must know that this Guiyuan Sea is different from the sea surface of any place, even if it is a fourth-order Guiyuan ship sailing on it, it will definitely not cause even the slightest ripple fluctuation, but as soon as Wu Yan's life talisman seal appeared, it actually caused this kind of abnormal movement, which shows its magic.

With the appearance of these ripples, the Fire Dao Yuan Essence that was originally erupting around them all subsided and did not move.

The blood-colored ball of light on the rune bone sword, after the appearance of the life-talisman seal, seemed to be inspired by some kind of power, like a milk swallow returning to the nest, flew towards the life-rune seal, and was sucked by the top hole of the life-rune seal, and disappeared.

The next moment, above the life talisman seal, a dazzling blood-colored holy light lit up, and its volume slowly expanded a little, although it was not too obvious, but Wu Yan could clearly sense that it was indeed expanding.

"Although the quality is still inferior, it seems to be much stronger than the original. The essence and blood essence of the Devouring Yuan Holy Beast is really useful for improving the quality of the life talisman seal. If you absorb more of this essence and blood, you should be able to raise it to a medium-grade level. ”

After carefully feeling the change of the life talisman seal, Wu Yan muttered in surprise.

Wu Yan immediately opened his eyes and put away the Rune Bone Sword and the Destiny Talisman Seal at the same time, and then his gaze fell on the cortex layer of the Swallowing Yuan Holy Beast wrapped around his arm.

This cortex is very strange, and I don't know what kind of material it is, it actually gives Wu Yan a feeling that it cannot be destroyed. What made him even more strange was that there was no treasure on this cortex, as if it were an extremely ordinary transparent snakeskin.

It's just that Wu Yan knows very well that it is absolutely impossible to be like what it sees, and it must have its special features.

Thinking of seeing the Swallowing Yuan Holy Beast before, it was by relying on this cortical layer that it could swim in the Guiyuan Sea with great ease like a swimming fish and sea snake, Wu Yan couldn't help but have an extremely bold plan in his heart.

If you can refine this cortical layer into a leather armor and wear it on your body, will you be able to swim in this Guiyuan Sea like a Swallowing Yuan Holy Beast?

As soon as this plan floated in Wu Yan's heart, it instantly occupied Wu Yan's entire mind.

Because, if this plan can really succeed, it means that he will not only be able to obtain more essence essence, but also be able to go back and forth freely in the four seas of the Guiyuan Sea, collecting all the world essence essence.

Not only that, but he was even expected to enter the Dao Domain Holy Island to find out the true secret of Guiyuan Sea.

Thinking of this, Wu Yan couldn't contain it and wanted to refine this cortical layer.

However, he didn't dare to do it rashly.

After all, this is the Guiyuan Sea, and all the primordial power cannot be used, and if you want to refine this cortical layer, you really can't do it rashly.

Wu Yan's heart moved slightly, and the life talisman seal immediately flew out of his body and froze in front of him.

In the next moment, Wu Yan dragged the cortex layer in his hand towards the Destiny Talisman Seal Seed, and put one end of it on top of the Destiny Talisman Seal Seed.

The holy thought turned slightly, and a strange blood-colored holy light flickered above the life talisman seal.

The cortical layer that was on top of the Natal Talisman Seed began to melt with the flicker of blood-colored holy light, turning into wisps of transparent liquid, surrounding the Destiny Talisman Seed.

Seeing this scene, Wu Yan's eyes suddenly lit up.

It really worked!

The life talisman seal seed is a rune that is tempered by the essence blood essence through the life talisman seal formula, and the power it has is far from being comparable to the ordinary essence blood element, and there is indeed no problem in refining this cortical layer.

Soon, a cortical layer six or seven zhang long was refined into a thin layer of transparent liquid, wrapped outside the life talisman seal.

However, with the rotation of Wu Yan's holy thoughts, this layer of transparent liquid disappeared from outside the life talisman seal in the next moment, and appeared outside Wu Yan's body surface.

What's even more amazing is that these transparent liquids seem to be very few, but with the rotation of the holy thoughts, Wu Yan's body is completely enveloped at this time, and Wu Yan's body is gradually becoming transparent.

Perhaps it was the cortical fluid after refining, but the amount was not enough to completely cover Wu Yan, because Wu Yan was only in a translucent state at this time.

Looking at this situation, as long as he collected the cortical layer of one or two more Yuan Swallowing Saint Beasts and refined them with the Vital Talisman Seal Seed, he could completely become transparent.

Raising his hand and looking at his arm, under the slight movement of the holy thought, the transparent liquid in other parts of his body all poured towards his arm, and soon, Wu Yan saw that his entire arm had all disappeared, as if it did not exist at all.

In the mental sense, this arm also seems to be very different from the rest of the body.

This difference is related to the essence of blood and blood.

It was as if at this moment, most of the essence and blood power in his body had gathered on this arm.

Wu Yan immediately half-squatted down, stretched out this translucent arm, and stretched out to the surface of the Guiyuan Sea.

The next moment, Wu Yan found that his arm, like the previous Yuan-devouring Holy Beast, could easily enter the Guiyuan Sea, and he was not afraid of the kind of devouring power of the Guiyuanhai at all.

It worked!

Seeing this scene, Wu Yan knew very well that he had really found a way to enter the Guiyuan Sea this time!

However, at this moment, Wu Yan's heart also had a trace of doubt and incomprehension.

He believed that outsiders might not know the origin of the truth and reality of this Guiyuan Sea, and the four great saint clans of the Great Sage Realm would never know it. Especially this Yuan Swallowing Holy Beast, Wu Yan had clearly heard it before, the people of the Primal God Clan called out its name, but why didn't they understand this method of entering the Guiyuan Sea?

Could it be because of this cortical layer, only those who have the life talisman seal can refine it, and no one else can refine it?

These were just flashes in Wu Yan's mind, and they didn't make him entangled and delayed.

Shaking his head and leaving these behind for the time being, Wu Yan immediately put away the life talisman seal. The clear liquid that had been attached to the surface of his body immediately burrowed into his skin and disappeared.

Regarding this situation, Wu Yan seemed to have expected it and did not take it to heart.

He immediately unfolded the Holy Awakening, searched out, and soon found the location of the Beacon Sky Fire and the Yuan-Swallowing Holy Beast.

At this time, the two were engaged in a fierce battle.

The Swallowing Yuan Holy Beast tried its best to swallow the Beacon Sky Fire, and the Beacon Sky Fire was even more dangerous at this time.

Losing the floating board, relying on the third-order Guiyuan Sword alone, although his speed is much faster, his situation is even more dangerous, and there is a possibility of falling into the Guiyuan Sea at any time.

Not only that, but the consumption of his immortal power was also several times as much as before. He had already spent seventy or eighty percent of the power of immortal consciousness, and at this time, he was desperately urging the third-order Guiyuan Sword, no accident, but he was afraid that before he found the Guiyuan Immortal Boat, he might die in the mouth of the Swallowing Yuan Holy Beast.

Wu Yan urged the third-order Guiyuan ship and chased after them unhurriedly.

A few moments later, Wu Yan was less than a hundred zhang away from the Swallowing Yuan Holy Beast.

At this time, Fengtianhuo, who was desperately fleeing, also noticed Wu Yan and couldn't help but shout to him for help.

It's just that when he saw Wu Yan's appearance clearly, there was a hellish expression on his face, and his mouth opened wide in shock, completely unable to believe what he was seeing in front of him.

"You, how come you have a Guiyuan ship?"

Wu Yan didn't bother to talk nonsense with him at all, raised his hand and sacrificed the third-order Returning Yuan Sword, slashed at him, and at the same time summoned the Rune Bone Sword, under the urging of the Holy Thought, it turned into a bone light, and stopped in the nearby area, waiting to strike a fatal blow at the Swallowing Yuan Holy Beast at any time.

Seeing that Wu Yan mercilessly sacrificed the third-order Guiyuan Sword and slashed at him, Feng Tianhuo's face flashed with anger and fear, and he shouted: "Ancient Heavenly Daoist Friend, stop it! If you have something to say, as long as Daoist Friend can let go of Zai Xia and give him a helping hand, I will swear to Heavenly Dao that after I leave here, I will definitely thank you for today's kindness! Besides, if you kill me, this terrible beast will definitely not let you go! Why don't you and I join forces to deal with it?"

"Fengtianhuo, there is no need to talk nonsense. When you hunt me down, you should have the consciousness of being killed, and go on your way with peace of mind! Your companion is waiting for you. ”

Wu Yan was unmoved, and said to Fengtian Huo with an expressionless face, but his subordinates didn't stop, and the third-order Guiyuan Sword had arrived in front of Fengtianhuo in an instant, and slashed down towards the top of his head.

Feng Tian hurriedly retreated in fright, and at the same time shouted in fear: "Ancient Heaven Daoist, don't kill me! I can agree to any conditions, as long as I can spare my life! As long as you can save me, I am willing to be your slave and serve you, I still have many secrets, you will definitely be interested!"

Just as Wu Yan attacked Fengtian Fire with the Guiyuan Sword, the Yuan-devouring Holy Beast also opened its bloody mouth and bit towards Fengtianhuo!

Not only that, but under the water area that Beacon Fire couldn't detect at all, its tail also cracked a bloody hole at the same time, striking Beacon Flame from behind.

Looking at this posture, Fengtianhuo will not be able to escape its devouring no matter what it is this time.

Wu Yan was not interested in taking Fengtianhuo as a slave at all, because when he heard his cry for mercy, Wu Yan didn't pay attention to it at all, and just cooperated with the Swallowing Yuan Holy Beast to attack him with the Guiyuan Sword.

Seeing that the blood mouth of the Devouring Yuan Holy Beast and Wu Yan's Guiyuan Sword were about to force themselves into a dead end, Feng Tianhuo shouted again, and shouted in horror: "I know a big secret of the Desolate Heaven Ancestor Tomb! This big secret is related to the Heavenly Machine Tower, you will definitely be interested!"

Just as he shouted these words, the blood mouth that had been split in the tail of the Yuan Swallowing Holy Beast had already reached the top of his head, and he didn't realize it, seeing that the Fengtian Fire was about to be swallowed by the Yuan Swallowing Holy Beast, a bone light, suddenly flashed, and the last hair came first, falling into the blood mouth of the tail of the Yuan Swallowing Holy Beast.

As this bone light fell, the tail of the Yuan-Swallowing Holy Beast also fell into the Guiyuan Sea.

Fengtian Fire stepped on the Guiyuan Sword and escaped from the blood mouth of the Yuan-devouring Holy Beast. However, Wu Yan's Guiyuan Sword blocked his retreat from the rear.

At this time, the body of the Swallowing Yuan Holy Beast was also completely submerged into the Guiyuan Sea and disappeared.

Shocks and fears appeared on Feng Tianhuo's face.

He never thought that this alchemist named Gu Tian would be so powerful that he could even deal with this kind of Yuan-swallowing holy beast!

"Next!"

Wu Yan threw out the floating board that he had put away before and landed near the beacon fire.

Feng Tianhuo hurriedly took off from the Guiyuan Sword and landed on the floating board.

"Fengtianhuo, my patience is limited, give you ten breaths of time, if you can't move me, you still have to die!"

"How the hell did you get that beast to disappear?"

Feng Tianhuo had just stood still, and he looked at the direction in which the Swallowing Yuan Holy Beast had disappeared and asked Wu Yan in shock.

"You're wasting time, there's still eight breaths of time!" Wu Yan stared coldly at Fengtianhuo.

Feng Tianhuo saw that his small movements were recognized, his face changed slightly, and he hurriedly said: "So, you really have an extraordinary relationship with the tower master of Tianji Tower?"

"Die!"

Wu Yan snorted coldly, urged the third-order Guiyuan Sword, and slashed towards the Fengtian Fire again.

"I said, in the central area of the Wasteland Ancestral Tomb, there is a mysterious big city, and there is also the Heavenly Machine Tower in it. I've been to the Tomb of the Desolate Heaven Ancestor a few times before, and I've been lucky enough to get a key that seems to be able to enter that big city. It's just that I haven't been able to find a way to activate the key. I've heard that the people of the Heavenly Machine Tower may know how to activate the key, so that's why I asked! Don't get me wrong. Feng Tianhuo hurriedly said, when he said this, his eyes were still staring at Wu Yan, but unfortunately, to his disappointment, Wu Yan heard his words, but his face did not change at all.

It's just that Feng Tianhuo can't know that when he heard his words, Wu Yan's heart was flooded. The key mentioned in the mouth of Fengtian Fire is the key to entering the Holy City of the Divine Machine - the Divine Machine Key!

Only with the Divine Machine Key can you enter the Divine Machine Holy City. And Mo Tianji had told Wu Yan before, the way to find the key of the divine machine, but even he was not sure that if he entered the tomb of the Ancestor of the Wasteland, he would definitely be able to find the key of the divine machine.

It is precisely for this reason that this mission is as high as a five-star rating.
