Feeling the changes in the thunder battle spirit, Xie Aoyu was very excited in his heart, the evolution of the war soul is very difficult, this is what Xie Aoyu learned from the evil spirit, even if it is an evil spirit, after an unknown number of years, it has only reached the upper position of the heavenly king level, and it is sealed into the magic card, and it also needs to be determined according to the strength of the person who released her, and the strength of the power she exerts.

The Thunder Soul is much luckier.

First of all, he obtained the Thunder Soul Holy Stone, was able to sublimate, and achieved the realm that is now close to the Ten Kings level, and then with the help of the Crystal Holy Dragon, through the Heavenly Thunder Quenching, even if he does not evolve, he can change the overall quality, and then achieve the improvement of combat effectiveness.

As a puppet-like existence of Xie Aoyu.

The stronger the combat power of the two thunder battle spirits, the corresponding increase in Xie Aoyu's combat power, of course, he was excited.

Looking at the transformation of the two thunder battle souls, Zi Yan couldn't help but think of the spirit dragon beast, the spirit dragon beast that had already transformed into a dragon body, had not completely transformed, and now it had been baptized by the double bloodline of the Xuanjia Yin Water Dragon King and the Bird of Paradise, and its beast blood had truly transformed into dragon blood that could make many people blush, and it was still a dragon blood that played a very big role, making the spirit dragon beast completely possess dragon nature, and there was no slightest beastly breath.

What's more, the transformation of the Spirit Dragon Beast has made it truly have the foundation to achieve the First Holy Dragon, and its growth is only a matter of time.

The spirit dragon beast of the peak realm of the ten kings is no longer as difficult as it once was to break through.

It's only a matter of time before you become a war king.

Even the pinnacle level of the Battle King is extremely likely.

Every time she thinks of this, Zi Yan sighs with emotion, since she and Xie Aoyu left Langya City, every time they meet, there will be this unexpected change.

Such changes always make Zi Yan indescribably happy after the fact, which is a wonderful memory of them fighting side by side and going through life and death.

When the Crystal Holy Dragon completed its movements, the heavenly thunder condensed in the sky began to converge towards the two thunder battle spirits in a regular manner, and countless subtle electric lights converged to form thunder and lightning as thick as an arm, constantly enhancing the power of the two thunder battle spirits.

During this period, the Thunder Soul Guiding Heavenly Thunder also attracted the attention of many elders on Shengjia Island, and Xie Aoyu gave some explanations to the second elder Krona.

And from the second elder Krona, Xie Aoyu also knew that the thunderstorm would last for a month, until the end of the Heavenly Selection Ceremony, of course, this did not indicate that it would rain for a month, but only that the thunder and lightning would last for a month.

"Hasn't the little devil woken up yet?" Xie Aoyu sent the second elder Krona away, and found that Qin Yueyi hadn't come out yet, so he asked casually.

The Crystal Holy Dragon showed a soft smile, "She is very snooze, and I have made certain modifications to her body so that she can break through as soon as possible, so she may need to sleep a little longer." After a pause, he continued: "Before the Xuanjia Yin Water Beast died, I forcibly read a little bit of its memories, and after the integration of these two days, these incomplete memories came to an astonishing conclusion. ”

"What a conclusion!"

Xie Aoyu and Zi Yan asked at the same time.

They had long known that the Crystal Holy Dragon had read a little bit of the memory of the Xuanjia Yin Water Beast and had been sorting it out, so they didn't think it was strange.

"The Angel Clan was devastated, but the Angel Clan was also prepared, they migrated some of their clansmen to the easternmost part of the distant sea, through the efforts of these tens of thousands of years of reproduction, they performed Angel Regeneration Technique, and also made some angel souls reshape their bodies, and the Angel Clan gradually grew stronger, and carried out a race-wide evolution 20,000 years ago, and finally achieved the Heart Tribulation Clan. After sorting through the broken memories he had read, the Crystal Dragon slowly recounted, "But the Heart Tribulation Clan is not perfect, and they have fatal weaknesses. ”

"What weakness?" Xie Aoyu said overjoyed. Xuanshu Literature Network

The Crystal Holy Dragon shook his head and said, " This should be hidden deep in the deepest part of the memory of the Xuanjia Yin Water Beast, and the fragmented memories I read are only a small part, and there is no weakness what, but according to the integration of the broken memories left by the Xuanjia Yin Water Beast, it seems that the weakness of the Heart Tribulation Clan can be said to be fatal, once it is caught, it will be devastated, which is also the price of the final evolution of the race, that is, it will leave an Achilles heel in exchange for stronger strength, and this is also the reason, many races that were very powerful in ancient times did not choose the ultimate evolution。 ”

Achilles' heel?

Xie Aoyu linked these four words with the Heart Tribulation Clan.

"But according to the memories of the Xuanjia Yin Water Beast, as early as after the Heart Tribulation Clan completed their evolution and discovered this Achilles heel, they gave up the opportunity to intervene in the chaos of the continent 10,000 years ago, and after 10,000 years, the purpose was to solve this Achilles heel. The Crystal Holy Dragon said, "Even if it is not completely solved now, I am afraid that it will not be so easy to be discovered." ”

"As long as they have weaknesses, they will definitely be able to find out!" Xie Aoyu said excitedly.

For a long time, the Heart Tribulation Clan has been like a mystery, and outsiders know almost nothing about them, and as they gradually get closer, the veil of mystery of the Heart Tribulation Clan is gradually being lifted.

Zi Yan asked, "In the memories you read, is there any inside story about why the Heart Tribulation Clan wanted to deal with the Dragon Clan?"

The Crystal Holy Dragon sighed: "No, but part of the reason should be that the Xuanjia Yin Water Beast was very dissatisfied with the expulsion of the Dragon Clan in ancient times, and the intention of revenge is one reason, and the other main reason has not been discovered, but I feel that the picture in the memory of the Xuanjia Yin Water Beast seems to have a very close connection with the Dragon Emperor Tyrannosaurus Rex." ”

Both of them were silent.

If it is related to the Tyrannosaurus rex, it is very likely to be related to the Tyrannosaurus rex's restraint on them, otherwise, do they still need to be afraid of the Tyrannosaurus rex? After all, the two are equally powerful existences of the same level, but the Tyrannosaurus rex does not know whether it still exists.

"Anything else?" Xie Aoyu asked.

The Crystal Holy Dragon said: "There is also the station of the Heart Tribulation Clan, I read it!"

"Really!"

"Great!"

Xie Aoyu and Zi Yan blurted out excitedly.

Now the Heart Tribulation Clan is secretive, they are waiting for the opportunity to make a move, if they can be found in advance, then they can be eradicated first, preventing them from making a move at a critical moment.

"Where is it?" Zi Yan said.

"The Angel Clan first migrated to the easternmost part of the sea, but after completing the evolution and becoming the Heart Tribulation Clan, they changed their location at the first time and moved to a giant island in the southernmost part of the sea area of the Qiao Continent, which is one-fifth of the area, which can be regarded as a piece of land. The Crystal Holy Dragon said, "But it's too far away from us, according to the memory of the Xuanjia Yin Water Beast, with his Battle King-level strength, it will take nearly a year to travel back and forth, if you take the initiative to attack the Heart Tribulation Clan, I'm afraid you will have to be prepared to spend several years." ”

Xie Aoyu grinned and said, "A year's journey back and forth?

The Crystal Holy Dragon snorted coldly, "They are afraid that their Achilles' heel will be discovered. ”

"The more this is, the more intriguing it is," Xie Aoyu said with a smile, "What is the Achilles heel of the Heart Tribulation Clan?"
