Call!

As soon as he thought of it, Lin Yun immediately crossed his knees on the ground, turned his hand and put the remaining gray crystals into his mouth.

"Boom, boom, boom!"

The moment the gray crystal was sent into his mouth, a stream of powerful spiritual energy immediately exploded in Lin Yun's mouth, rushing towards Lin Yun's mental space, Lin Yun's spiritual power immediately increased rapidly like a fire seeing the wind, and at the same time, Lin Yun's mind was clear.

"The level of this spiritual energy is so high, it is estimated that it can enhance the spiritual power of the second-level cultivators of the Super Realm......

Lin Yun was secretly shocked.

Previously, because there were not many gray crystal fragments under his suit, although the spiritual energy born was huge and the level was not low, it was far inferior compared to the spiritual power of a second-level cultivator of the Super Realm, and it was quickly diluted in his mind space, so he only judged that the level of this spiritual energy was not low, and it was absolutely harmless to him, and he did not judge the specific level of this spiritual energy.

Now, he judged.

A natural treasure that can increase the spiritual power of the super strong...... It is still a heavenly and earthly treasure that can increase the spiritual power of a cultivator of the second level of the Super Realm......

The value of this level of Heaven and Earth Treasure was immeasurable, far exceeding the value of those Heaven and Earth Divine Hearts that he had purchased before.

Perhaps, only the super golden source liquid given to him by Xiao Jin's mother could be compared to this gray crystal.

"Could it be that this gray crystal is the reason why a second-level ghost cultivator of the Super Realm is left?" Lin Yun said thoughtfully.

Thinking like this, Lin Yun couldn't help but feel a trace of excitement in his heart, didn't this mean that if he met other ghost cultivators in the future, once he killed the other party, he might also be able to obtain such a gray crystal.

Moreover, the stronger the opponent's strength, the higher the level of gray crystals he obtains?

Then he originally judged that in the end, he might encounter the matter of the third-level ghost cultivation of the Super Realm......

The more I thought about it, the more excited I became.

But soon, Lin Yun put this thought down.

Is this the case in this matter, when he encounters other ghost cultivators later and kills those ghost cultivators, it can be determined that the most important thing for him now is to digest this gray crystal well.

"Whew, whew!"

Lin Yun closed his eyes and began to quickly refine this gray crystal.

He found that the spiritual energy emitted by this gray crystal was very easy to refine, far exceeding the refining speed of the Heaven and Earth Divine Heart, and it was because of this that he decided to refine this gray crystal on the spot.

Otherwise, he only has half a year left to break into the Heavenly Dao Tower, and I'm afraid he will waste most of his time here.

The higher space of the Heavenly Dao Tower, he was still very curious about what kind of scene it was, how could it be wasted here like this?

One day...... Two days...... Three days......

Although the spiritual energy in this gray crystal was refining very quickly, the spiritual energy contained in it was too huge, and it still took Lin Yun a full three days to refine all the spiritual energy in it.

"Hum—"

Just as Lin Yun had finished refining all his spiritual energy, Lin Yun's mind space suddenly shook, and a magical fluctuation emanated from his spiritual power, and his spiritual power began to transform rapidly.

But at this time, his spiritual power broke through from the late twelfth level realm to the twelfth peak realm.

Yes, Lin Yun's original spiritual power was only at the late twelfth level, although he had already obtained an extremely high-level Heaven and Earth Divine Heart from the Eastern Emperor, which was enough for him to raise his spiritual power to the twelfth peak level, but the time required to refine the Heaven and Earth Divine Heart was not short.

He hadn't had time to refine those Heaven and Earth Divine Hearts in large quantities.

His spiritual power was only at the level where he was not weak at the late twelfth level.

This time, it only took three days to raise the spiritual power to the peak of the twelfth level, which is indeed not comparable to refining the Heaven and Earth Divine Heart.

"Those Heaven and Earth Divine Hearts can only improve the spiritual energy of the twelfth peak level, this gray crystal, if I am not mistaken, it should be able to improve the spiritual power of the second level powerhouse of the Super Realm...... I knew that I would have used those Heaven and Earth Divine Hearts first, and then I would have used this gray crystal, and now, if I use those Heaven and Earth Divine Hearts again, the effect will be greatly reduced, and it will be difficult for me to impact the Super Realm level......"

After half a day, Lin Yun stabilized his spiritual power level, opened his eyes, and said with a slight sigh.

He couldn't help but feel a pity in his heart, first using low-level heavenly materials and earth treasures, and then using high-level heavenly materials and earth treasures, this is a normal routine...... Now, it's a pity.

"However, if you use the Heaven and Earth Divine Heart, I don't know how long it will take to refine, I'm afraid that if I can't refine it in this Heavenly Dao Tower, I won't be able to increase my strength in time......," Lin Yun thought after a pause.

Thinking about it like this, the pity in Lin Yun's heart decreased a lot.

Now that he is breaking into the Heavenly Dao Tower, the stronger the strength, the better, especially, at this level where he is breaking now, it is very likely that he will encounter many ghost cultivators who are good at spiritual power attacks, and naturally the higher the level of spiritual power, the better.

As for those heaven and earth gods...... If it's not easy to use, don't use it, wait for him to go out, let Mengmeng and Qingqing and others use it, it's also good, just right, they either have a low level of spiritual power, or their comprehensive strength is low, if they use this kind of gray crystal, I'm afraid they won't be able to bear it, that kind of gentle temperament, slow refining of the heaven and earth divine heart, just right for them.

"Three and a half days ......"

After figuring it out, Lin Yun raised his head, and his black pupils shrank slightly.

Refining the gray crystal, he spent a total of three and a half days, depending on the situation, this kind of thing, he can't do too much.

Otherwise, the time for him to break into the Heavenly Dao Tower would be reduced a lot.

Call!

Lin Yun's mind moved, and he began to move forward.

And look at the scene of this space.

I saw that this continuous mountain range was very tall and majestic, but it was full of yin and dense atmosphere, Lin Yun estimated that this should be a yin attribute mountain range, which was a good place for ghost cultivation to survive in the legend.

"I really don't know how this kind of environment was born, or is this just a simulation of the Heavenly Dao Tower?" Lin Yun said secretly.

After breaking through a total of forty-nine floors of the Heavenly Dao Tower, Lin Yun now had a faint guess about the various scenes simulated by the Heavenly Dao Tower, and he estimated that even if these scenes were not real, they must be very reasonable.

Not long after, Lin Yun once again encountered a powerful ghost cultivator, whose strength was stronger than the one just now, but it was still in the second level of the Super Realm, and this ghost cultivator seemed to be relatively cunning, and some sneak attacks and stratagems would be used.

"Poof!"

In the end, Lin Yun spent a lot of effort to kill this ghost cultivator.

"It's really not easy to ......" The moment he was killed, Lin Yun couldn't help but sigh.

At the same time, his spiritual power immediately covered this place where the ghost cultivator had fallen, and he was looking for that gray crystal......

"Sure enough!"

Soon, Lin Yun's eyes lit up, and his heart was happy.

Sure enough, he found a gray crystal in the place where the ghost cultivator had fallen, about the same size as the last time he found it.

Lin Yun's mind moved, and the person had already flashed to the side of the gray crystal, and the next moment he grabbed the gray crystal in his hand.

"It's exactly the same!" Lin Yun smiled slightly.

"Let's refine this gray crystal first! The second ghost cultivator, it's not easy for me to deal with, it's still in the second level of the super realm, if I encounter the third level of the super realm ghost cultivator in the future, or two at a time, it will definitely be even more difficult to deal with......"

"The increase in the level of mental power makes it easier for me to deal with the spiritual attacks of these ghost cultivators, and makes my various reaction speeds faster, as the saying goes, sharpening the knife does not mistakenly chop wood, I spend some now, but all together, it may not really take much time......

Lin Yun thought for a moment in his heart and said secretly.

"Whew!"

Lin Yun crossed his knees on the ground and refined the gray crystal again.

The quantity and quality of his spiritual power have once again entered an explosion.

"Buzz-buzz-buzz-"

Just as Lin Yun was refining this gray crystal, the Blood Devouring Sword that Lin Yun placed on his lap emitted a blood-red light that flickered and dimmed, and trembled violently, letting out a soft roar.

Lin Yun didn't pay attention to it, when he was refining the gray crystal now, the Blood Devouring Sword reacted like this.

He believed that this was the natural reaction of the Blood Devouring Sword when the power in his body changed drastically.

After all, now that the power of the Blooddevouring Sword is merging with his strength, his spiritual power has skyrocketed, and it is normal for the Bloodthirsty Sword to react.

"Boom-hoo-"

However, this time, without waiting for Lin Yun to refine much spiritual energy, the blood-colored light emitted from the Blood-Devouring Sword suddenly skyrocketed, and a powerful force suddenly poured into Lin Yun's body from the Blood-Devouring Sword, quickly rolling up a huge stream of spiritual energy back into the Blood-Devouring Sword, and then, the blood-colored light released by the Blood-Devouring Sword became even stronger.

"What?"

Lin Yun was taken aback, and quickly opened his eyes and looked at the blood-devouring sword on his lap.

It has always been him who kills, and the Blood Devouring Sword absorbs the opponent's essence blood power, and then, part of the essence blood power is absorbed by the Blood Devouring Sword itself, improving itself, and part of it is fed back to Lin Yun to enhance Lin Yun's strength.

There had never been a situation where the power he had increased by using the Heavenly Treasure would also be absorbed by the Blooddevouring Sword.

"Boom!"

Lin Yun got up and immediately took the Blooddevouring Sword from his lap, and a force enveloped the Blooddevouring Sword, causing the Bloodthirsty Sword to levitate in front of him, detached from his power.

"Little blood, you dare to absorb Brother Lin Yun's power!"

"Little blood, how can you do this?"

At the same time, there were also two angry voices from Xiao Bai and Xiao Lan in the Blood-Eating Sword, and then, three light clusters chased after each other in the Blood-Eating Sword, attacking each other, but they were fighting.

"Xiaobai, Xiaolan, what's going on?"

Lin Yun asked in a deep voice.

The Bloodthirsty Sword is undoubtedly a very ungodly magic weapon, and it is not a good phenomenon that it is out of control now, especially when Xiaobai and Xiaolan are also supervising in the Bloodthirsty Sword.

Lin Yun didn't think that Xiao Bai and Xiao Lan had become a gang with the spirit of the Blood Devouring Sword itself.

"Brother, this little blood suddenly broke away from the connection with me and Xiaolan just now, and absorbed your power......"

"Brother, it's all because we didn't take a good look at it, don't worry, we will be optimistic about it next, and we won't let it ...... nonsense"

Xiaobai and Xiaolan hurriedly said, their tones were very angry.

"How's that guy's strength now, can you two be optimistic about it?" Lin Yun frowned.

This question is very important, he fused with the power of the Blooddevouring Sword, and only now has the current strength, if he can't fuse with the power of the Bloodthirsty Sword, his strength will not be easy to fight with the ghost cultivator just now.

This fiftieth layer of the Heavenly Dao Tower, I'm afraid it will never be able to break through again.

What's more, Xiao Bai and Xiao Lan can't be optimistic about the spirit in the Blood Devouring Sword, and when the key battle is due, let this guy fight back, then it will be miserable.

Didn't the previous blood-eating demon Nan Weng be killed like this?

Lin Yun didn't want to step into the fate of that Nan Weng.

"During this time, its strength has increased a lot, but Xiaolan and I are not vegetarians, and we have grown a lot, Xiaolan and I can still watch it, brother, don't worry, just now, Xiaolan and I didn't pay attention, now, let's beat it up first......" Xiaobai's immature voice, indignation came.

Listening to Xiaobai's words, Lin Yun's frowning brows still did not expand, as the saying goes, the twisted melon is not sweet, and it is not a good way to forcibly make the other party obedient like this.

He could feel that the weapon spirit of this blood-devouring sword was very cunning, although Xiaobai and Xiaolan's wisdom was high, but they had too little experience, and if they talked about conspiracy or something, they were probably not the opponent of this blood-devouring sword weapon spirit.

In case, Xiaobai and Xiaolan fall into each other's hands, the three of them are afraid that they will all be planted on this sword.

"Is it really only your own strength that is reliable......

Lin Yun sighed faintly.

If so, his strength is all his own strength, and he doesn't rely on any external force, why is he so worried?

The Bloodthirsty Sword is powerful, and once something goes wrong, it's also a headache.

"Forget it, Xiaobai, Xiaolan, don't deal with this guy, rest for a while, during this time, I won't use the ...... of the Blooddevouring Sword first" Lin Yun thought for a while and said.

He really didn't dare to use this kind of out-of-control blood-devouring sword, in case he was in the middle of the battle, he would lose a lot.

Previously, Lin Yun's impression of this guy, with this incident, came up one by one again, this guy was too cunning, even if Xiaobai and Xiaolan suppressed each other, he was not particularly relieved.

Perhaps, this guy was suppressed by Xiaobai and Xiaolan, and he has been hiding his strength?

still don't let Xiaobai and Xiaolan deal with each other, in case, the other party can't bear it anymore and suddenly explodes in strength, and it will be even worse to treat Xiaobai and Xiaolan well.

It's better to wait for him to return to Earth and let Xiaobai and Xiaolan leave this blood-devouring sword.

Perhaps, as he found that this blood-devouring sword was becoming more and more difficult, he became more and more jealous of this blood-devouring sword in his heart, but nothing had happened before, so he subconsciously ignored this matter.

After all, the Bloodthirsty Sword is too rebellious, and his use of the Bloodthirsty Sword and not using the Bloodthirsty Sword are almost two strengths, which is too tempting.

At this moment, Lin Yun was sober.

His idea of relying too much on the Blood-Devouring Sword was very bad.

Perhaps, he should have gotten rid of it sooner.

That's it, it's not bad that he only broke into the fiftieth floor of the Heavenly Dao Tower, the environment here is okay, he has been cultivating here for a while, even if he can't break through to the super realm, his current results, it should be possible for him to obtain a Heavenly Dao Fruit.

He can also use the Heavenly Dao Fruit to break through to the Super Realm.

In addition to the Blood-Devouring Sword, he also has the Demon Sound Bell, and the Demon Sound Bell also has a good attack effect on those ghost cultivators, but he didn't use the Demon Sound Bell when he had the Blood Devouring Sword before.

Next, he used the Magic Sound Bell, and maybe he could also get a few more gray crystals of that kind, which would be a big gain.
