On the second floor of the Thunder Cloud Treasure House, by the Baihua Pond, Lin Yun sat cross-legged.

Boom!

There was a low sound of thunder, resounding in Lin Yun's body, and the surface of his body was like a tree root formed by the condensation of countless thunders. Under the training of this kind of thunder power, the thunder-patterned film on the surface of his skin changed from light to dark, and finally turned purple, like a glass of glass.

The power of thunder contained in the Xuan Leizhu is majestic and thick to an astonishing level, and it is extremely violent.

If it weren't for Lin Yun's physical heritage, it would be dangerous to refine it like this. But even so, when the terrifying power of thunder poured into the meridians, it was still a bit tingling. But compared with the pain that Lin Yun had when refining the Canglong blood before, it was completely incomparable.

boom!

With the continuous influx of pure thunder power in the Xuan Leizhu, the icy purple iris flower in the Zifu has quietly changed a little.

Such terrifying power of thunder, in addition to nourishing the body and strengthening the Nine Transformations of the Canglong. Inevitably, it will merge with his own true essence. In just half an hour, Lin Yun was surprised to find that his cultivation was actually increasing a little.

This is quite a surprising thing. Since his cultivation base has been promoted to the Yang Profound Realm, he has almost never moved, and has not been able to advance an inch.

The unexpected joy at the moment really made Lin Yun feel a lot of excitement in his heart.

Lei Mang flickered, reflecting Lin Yun's cold face, and his expression was quite dignified. In such a tense refining, he was thoughtful and moved, and at the same time, he activated the Ziyuan sword energy, and actively merged the majestic true essence with the power of thunder.

During the operation of the exercises, the two quickly merged.

Whoa!

In that silver purple mansion, countless thunderbolts turned into rain and dew, and fell down. Between the fusion of the two, Lin Yun clearly felt that the power of his true essence had become extraordinarily condensed at an astonishing speed.

"Interesting... My realm has advanced by leaps and bounds before, and my cultivation base has skyrocketed, and my roots are basically unstable. With such an active fusion, the power of thunderbolt of Xuan Leizhu can actually play such a role."

In such a short time for a cup of tea, Lin Yun felt that his majestic True Essence became a little heavier.

As time passed, the energy surging in the Profound Thunder Orb in the palm became more and more ferocious. In a faint, Lin Yun felt a little unable to resist, as if he wanted to explode his body.

"We must take this opportunity to transform Canglong into the third floor..."

Lin Yun's expression was solemn, and he secretly said in his heart that if his physical body could not go further, he would not be able to continue refining this mysterious thunder ball.

Lin Yun, who had enjoyed so many benefits, naturally would not give up so easily.

With a slight movement in his mind, the Canglong Nine Transformations suddenly began to run wildly, guiding the power of thunder that poured in from the Xuan Leizhu. Continuously pounding, the last few meridians of the third level of Canglong Nine Transformations broke through this bottleneck with supreme perseverance.

After being stagnant for so long, it is time to hit the third level.

Boom!

Under this kind of impact, Lin Yun's whole body was suddenly shaken, and the entire palace shook violently under the impact.

Once, twice, three times... Nine times, when it hit the ninth time, Lin Yun's throat was so sweet that he almost spat out blood, and his internal organs were in extreme pain.

But under this kind of stimulation, Lin Yun was overjoyed. He clearly felt that before this, he didn't move at all, just like the bottleneck of the mountains, there was a big loosening.

The joy is beyond words.

When he calmed down, Lin Yun's cold face flashed with ruthlessness.

Bang! Bang! Bang!

In the violent collision, Lin Yun trembled and endured great pain. On the surface of his body, those entangled with the power of thunder are no longer tree roots with vigorous vitality, but more like strips of violent thunder, churning wildly, constantly infiltrating.

The entire palace trembled constantly under this terrifying impact. The top of the head was cracked, and broken stone chips fell one after another.

click!

Two hours later, when Lin Yun was a little numb, a crisp dragon roar suddenly erupted from his body. The last meridian, under such crazy impact, was finally completely broken through.

Canglong Nine Changes, successfully promoted to the third level.

A stream of extremely pure thunder energy burst out continuously in Lin Yun's body, and was then absorbed by his internal organs. The inside of its body was almost dyed with purple thunder, and the flesh, skin, bones and muscles had undergone qualitative changes.

At the same time as the internal qualitative change, those ancient thunder patterns on the surface of its body crawl wildly. Like twisted rivers, they converge towards the mouth of the heart.

When all the thunder patterns poured into my heart, they kept mixing and changing.

boom!

After a while, a dazzling thunder light erupted from Lin Yun's heart, dazzling, like a big sun.

After the light passed, a Longxing mark was imprinted on the heart. The imprint is soul-stirring, has an ancient charm, and exudes a touch of dragon power. With the throbbing throbbing of the heart, it seemed to be vaguely alive and full of spirituality.

call....

Lin Yun let out a long sigh of relief, suddenly opened his eyes, and a powerful breath spread out from his body leisurely. Just the momentum is at least two or three times stronger than before refining the Profound Thunder Orb.

"Is this the Blue Dragon Seal?" Lin Yun thought about it, and then his mind moved slightly. The Blue Dragon Seal at the heart of his heart was radiant and generous, and then developed a line of thunder patterns, which instantly spread from the heart to the whole body. When the thunder pattern spread all over his body, his skin completely changed into a deep purple thunder color, shimmering and completely like metal.

.

The thunder-patterned armor has undergone a qualitative change at this moment.

Five fingers clenched tightly, and a force burst forth in an instant.

Canglong nine changes, the second change!

With a loud shout, lightning suddenly flashed all over his body, and his clenched right fist slammed into the ground.

A surging force penetrated in, and immediately spread to the ground of the entire palace.

Click!

Immediately afterwards, the ground exploded in an instant, and countless dazzling electric lights shot out through the cracks. The next moment, the hard floor that had not been completely destroyed in the previous battle between the three major yin and yang realms fell apart in an instant, and the sky was filled with dust.

Boom!

The entire palace was shaking violently, and after a long time, it was calm.

"Is this the power of the second transformation of Canglong Nine Transformations?"

Lin Yun was slightly speechless, and a very excited expression surged from the depths of his eyes. He is now quite sure that even without the use of swords, he can forcibly regret the existence of a yin-yang realm Xiaocheng peak, and even crush the opponent.

If it were the two relatively ordinary castle masters of the Three Eagles Castle, Lin Yun was confident that one punch could severely damage the opponent, and three punches would be enough to completely blow them up.

In addition to the increase in strength, Lin Yun was even more pleasantly surprised that, under the circumstance of condensing the Canglong Seal, the thunder pattern armor had undergone a complete qualitative change. From the previous skin, the fleshy skin has completely turned into a purple thunder-colored metal.

Strictly speaking, it is more accurate to call it the Canglong Battle Body.

"It's time to go to the third floor of the tomb palace."

Lin Yun looked calm and looked at the Azure Dragon Spirit Seal in the palm of his hand. Now he has enough confidence to face Feng Wuhen and the three of them.

Even if the three parties join forces, he is not afraid.

The only thing to worry about is whether there will be other changes in this Thundercloud treasure house.

At the same time, the Thundercloud Treasure House, the altar hall in the core area of ??the third floor.

Feng Wuhen and Old Man Gu were waiting anxiously.

The blood-devouring magic tome suspended on the altar is tempting enough to make people move. But what Lei Yunzi left behind before his death prevented the two of them from making the slightest rash move.

Especially Feng Wuhen, he tried rashly before, but the result was just a glance.

Those bloody eyes made him fall into the abyss, as if the blood all over his body had been frozen. With one blow, not only the body was knocked flying, but the whole soul felt a lot of trauma.

"Still still?"

Feng Wuhen, who was sitting cross-legged, Yunyou opened her eyes, and there was a flash of irritability in the depths of her eyes.

Sanyingbao can only rely on Leng Xiangyun to open the way. In terms of speed, it is far from the ancient head, even Master Fu. Even though he knew about this, Feng Wuhen was still a little impatient, and wanted to kill him back to help the other party break the restrictions encountered on the road.

Click!

At this moment, there was a sound of Shimen being pushed open, and Feng Wuhen and Gutou lit up at the same time.

But after seeing the person coming, a look of disappointment flashed in his eyes, it was Xuelang and Master Fu.

"Blood Devourer!"

The blood wolf saw the floating magic book on the altar, and the bright eyes immediately filled with endless greed.

"I advise you to stay still."

Just when he was about to make a move, there was Feng Wuhen's cold voice.

"What trick are you playing?"

The blood wolf woke up, looked suspiciously at Feng Wuhen, and doubts flashed in his heart. Since this guy has come a long time ago, why didn't he take the Blood Devouring Tome?

"See for yourself."

Feng Wuhen looked indifferent and pointed to the altar.

When the two of them saw the last words left on the altar, the blood wolf suddenly scolded: "This Lei Yunzi was not a good thing when he was alive, but after he died, he still played with people like this. We have come this far, where are we going? What kind of pure yin body is playing with us!"

Think about the hardships and hardships along the way.

After finally seeing the Blood Devouring Tome, how could he be angry with such a strange request.

"Tsk tsk, the body of pure yin... may not be absent."

A smile appeared on Feng Wuhen's youthful face.

Seeing Xuelang curious, Feng Wuhen did not say much, and said lightly, "When the people from Sanyingbao come out, everything will be known."

"Three Eagles Castle?"

The blood wolf and the old man Fu looked at each other, and thought of something in an instant, and lost their voice: "That girl... this old ghost is hiding so deeply!"

Click!

Just as the two were talking, Shimen was pushed open again, and the group walked out in a rather embarrassed manner.

It is the people of Sanyingbao.

call out!

Xuelang and Feng Wuhen looked like lightning, and instantly fell on Leng Xiangyun. The strange smiles on their faces scared Leng Xiangyun into hiding behind Fort Leng.

"You guys, what are you going to do?"

Looking at the two who were approaching step by step, Lord Lengbao showed a vigilant look in his eyes and shouted in a deep voice.

"What are we going to do, don't you know why, Lord Lengbao?"

Feng Wuhen said sarcastically.

Lord Lengbao's expression was cloudy and cloudy, and his thoughts were like electricity. When his eyes fell on the altar, he probably figured it out.

"Don't tell me cold old ghost, you will really bring your own daughter to this ghost place. It just so happens that this last altar needs a pure yin body blood sacrifice, I don't believe that there is such a coincidence in the world!" The blood wolf looked hideous , said coldly.

"Father... are they telling the truth?"

Leng Xiangyun suddenly turned pale with fright, and asked shiveringly.

"Xiangyun, I raised you for my father for more than ten years... I have some feelings, but this is your life!"

Lengbao master has come to this point and sighed.

Leng Xiangyun's face suddenly turned ashen, her eyes were blank, and her body shivered. She never thought that what she had been waiting for would be such a result along the way.

"Sure enough!"

Xuelang and Feng Wuhen had excited expressions in their eyes, and looked at Leng Xiangyun greedily.

For a time, this innocent and romantic girl was like a lamb to be slaughtered, suffering and despairing.

"It is said that some of the craftsmen who built this Thunder Cloud Treasure House escaped by chance. Are you one of them?" Feng Wuhen looked at Castle Leng and said softly.

"No. All the people in those days died, and it was me who did it, but I didn't expect it. I didn't even let this devil go. He worked hard to serve him all his life, and he helped him build this treasure house before he died, but he still had to Kill me with a blood curse."

Lord Leng revealed his memory, his cheeks trembled, and he looked quite excited, and said coldly: "It's just that this old guy didn't expect that although the blood curse tortured me, it was worse than death, but I held my breath and finally managed to get through it. ."

Xuelang and Feng Wuhen were stunned for a moment, obviously not expecting that this Fort Leng master was actually Lei Yunzi's servant during his lifetime.

Crunch! Just when the two were shocked, the last stone gate was slowly pushed open. Lin Yunshan came late, but he finally came.
