The thunder of the demigods, that is, the existence of a god giant can easily be obliterated.

To have this demigod thunder and exert its power, there are two conditions that must be met, one is to complete its advancement before it is killed, and the other is to have enough strength to be able to exert its full power, otherwise even if it is possessed, it can only be used as a decoration, and it is useless if you don't have enough power.

"Thank you for your help. Xie Aoyu said.

Shengshu smiled: "You're welcome, compared to your help to me, this is nothing." ”

"The predecessor is the origin of life, the goal of this Xuan Thunder advancement is the Holy Thunder, or even the thunder of the demigods, that is, it has spirituality, and if it has life, inferring from the feelings of the predecessors, how long will it take to complete the advancement?" Xie Aoyu asked.

"Ten years if it's fast, and a hundred years if it's slow. The Sacred Tree replied.

Soon, another ten years?

Ten years is nothing for a person in the realm of Xie Aoyu, it is just a moment in life, but the invasion of the divine realm is probably within two or three years, and if it is ten years, he will not be in a hurry at all.

"Is there a faster way?" Xie Aoyu asked.

"Then you need to use the ultimate thunder to catalyze, if there is a heaven and earth divine thunder born, it can also be intensified. The Sacred Tree replied.

Xie Aoyu was speechless for a while, saying the same as not saying it.

Extreme thunder, that is the limit of human beings' ability to grasp the natural power of heaven and earth, and there is absolutely no one in the entire human world who has the ultimate thunder.

As for the birth of the Heaven and Earth God Thunder, I am afraid that the chance of being born only once in hundreds of thousands of years, Xie Aoyu does not expect to encounter it.

The Sacred Tree continued, "Remember when I told you that I wanted to reward you?"

"Naturally, I remember that in the realm of my predecessors, the rewards must be very exciting, and I can't forget it. Xie Aoyu laughed.

"This is my reward for you!" A layer of flexible power quickly flowed on the branches of the holy tree, and quickly gathered on the main trunk, and soon a tender green leaf formed, and then broke away from the holy tree, fluttering towards Xie Aoyu, and fell into his hands.

When the tender green leaves fell into his hand, Xie Aoyu felt that there was a trace of wonderful energy fluctuations on it, but it was not life force, but an existence similar to spiritual power, and the leaves themselves carried a trace of pure life wood qi, which could also help Xie Aoyu's cultivation to a certain extent.

Xie Aoyu took the leaves and found that the role of this was not mainly to help him improve his realm.

"Senior, what's the use of this power?" Xie Aoyu asked.

The Holy Tree smiled slightly and said, "Promote your liquefied spiritual power to advance!"

Xie Aoyu's eyes exploded, staring at the holy tree, his breathing was a little heavy, liquefied spiritual power, that was his biggest killer weapon all along, just because since the beginning of the third-order War Emperor, he had entered a slow process of advancement, and he had not completed the advancement so far.

If the liquefied spiritual power completes the advancement, then he will have the ability to sweep through the tenth-order War Emperor.

After all, his spiritual power is liquidized, just like the absolute deterrence of combat power to fighting spirit, and the liquefied spiritual power is the absolute oppressive force of ordinary spiritual power.

"I've been observing your spiritual power since the last time you came in, and after ten days, I've finally deduced the progress of your mental power. A faint smile appeared on the Sacred Tree's face, "I'm afraid you don't even know it, your spiritual power has already exceeded the boundary of the Tenth Order War Emperor." ”

Xie Aoyu was stunned and said, "Is this really what the senior said?"

The holy tree smiled: "It shouldn't be wrong, the psychic divine tree and I are both at the tenth-order War Emperor level, it is the peak level of the tenth-order War Emperor, I am a newcomer, and then due to excessive consumption, I can only exert the power of the seventh- or eighth-order War Emperor, and now it has been restored, in order to verify the extent of your spiritual power, our spiritual power is fused, measured, the strength of the spiritual power, and as a result, our spiritual power is combined, and it immediately surpasses the tenth-order War Emperor, and even shakes the prohibition of the deep sea." ”

Thinking that the Xuan Ling was created by the ancient psychic divine tree, then the Xuan Ling can fuse any power that has the same mind, and the natural spiritual power is no exception, so it is understandable that the spiritual power of the psychic divine tree and the sacred tree are fused.

"My spiritual power is comparable to your combined spiritual power?" Xie Aoyu was somewhat surprised, he thought that it was equivalent to the spiritual power that had just stepped into the tenth order of the Battle Emperor.

"Not quite. The holy tree said with a smile, "It's our fused spiritual power, and it's only between one-fifth and one-third of your spiritual power. ”

"Huh?!" Xie Aoyu's eyes widened.

Between one-fifth and one-third?

And their spiritual power fusion has already surpassed the level of the tenth-order war emperor, and they can shake the slightest prohibition of the deep sea area on their own, obviously it is not comparable to the spiritual power of those masters who have just surpassed the tenth-order war emperor, so wouldn't his spiritual power have reached a very amazing level.

Xie Aoyu couldn't help but recall the reason for the advancement of his mental power at the beginning.

It is closely related to the Fighting God of the Fighting God Clan, and it is also related to the most mysterious Hell Blood and Bone King in the Hell Demon Realm, so that his spiritual power has been completely transformed.

Thinking about the Northern Sea, there are more than 50,000 years of time, grabbing the heaven and earth aura of the entire Northern Sea and sealing one place, more than 50,000 years, how much power does it contain, it is no wonder that his spiritual power is so difficult, even if he advances to the spiritual power of the tenth-order War Emperor, ordinary people can succeed in cultivation in only half a year, but what about his?

In this case, it can be explained.

"Your spiritual power is not only incomparable after being single, but also a little bit, it is still liquid, if you can advance perfectly, then when you step into the tenth-order war emperor, you will have the strength to sweep and kill the strong people who surpass the tenth-order war emperor. The holy tree continued, "I look at your spiritual power advancement, it seems that after entering a certain level, you have been supported by external forces and accelerated your advancement, maybe after you step into the peak level of the Ninth Order War Emperor, it is possible to make it complete the advancement, because this kind of advancement is somewhat related to the realm, now I will help you advance earlier, as long as you step into the Ninth Order War Emperor, or even reach the peak level of the Eighth Order War Emperor, you will complete the final advancement." ”

The Golden Divine Dragon had said before that he was able to complete the advancement of his spiritual power in the Ninth Order War Emperor.

With the strength of the Golden Divine Dragon, it was impossible to be wrong in what it said.

And this holy tree obviously can't be wrong, so why do you need support to be able to complete the advancement when you step into the ninth-order battle emperor?

The only explanation is that after the golden dragon slumbered, his spiritual power was transformed again.

But he didn't know about this kind of transformation!

When did the change come about?

Xie Aoyu muttered in his heart, and began to recall all the experiences after the golden dragon fell asleep, thinking about it, there were only two time periods that could stimulate the transformation of spiritual power without knowing it.

One possibility is that before leaving, the Divine Realm giant stated that he would take special care of him.

At that moment, Xie Aoyu was almost labeled as mortal, so it was possible for his spirit to transform, and since his spiritual power was always evolving, it was difficult for him to detect it.

Then there is the cannon fodder who learns that he is being used by the ancient psychic tree.

Two time points.

Obviously, the first possibility is more likely, because the inference of the holy tree is before he knows that he is being used, then that is to say, his spiritual power may also be advanced again because he knows the sad and angry fate of being used as cannon fodder by the ancient psychic divine tree and knowing that he is fighting for the human world, but being used as cannon fodder by the human world.

In the end, if you want to prove it again, it is easy to cultivate, if you can complete the advancement of spiritual power after stepping into the ninth-order Battle Emperor, it is not stimulated to change again, if you do not complete the advancement, then it is very likely to be stimulated by the ancient psychic divine tree, and the transformation has occurred again.

But no matter what, this support from the Holy Tree always accelerated his spiritual power advancement!

Next, Xie Aoyu began to cultivate.

He stayed in front of the sacred tree, absorbing the wonderful power in the tender green leaves, Xie Aoyu only needed to absorb it, and the wonderful power would turn into the sea of consciousness, and merge with the spiritual power in the advanced level, giving Xie Aoyu the feeling that the spring flowers were blooming, and the ice was slowly dissolving.

The slightest change was very weak, but it made him feel an indescribable feeling of being comfortable and in spirit.

At the same time, the pure life wood qi in the tender green leaves was also absorbed by Xie Aoyu, and then tempered and transformed into combat power, which further improved his cultivation, and in just an instant, he stepped into the peak level of the seventh-order War Emperor, and he was still moving forward.

Cultivation is a slow process, but beside this sacred tree, it is very fast.

Xie Aoyu, who was cultivating, suddenly felt that the life wood qi in this area had suddenly increased dozens of times, and at the same time, there was a powerful energy fluctuation, and he knew that the holy tree was helping the Holy Wood Divine Clan get out of trouble, and he didn't pay attention to continuing his cultivation, and his goal was to take advantage of this opportunity to rush into the eighth-order battle emperor.

Time kept passing, and Xie Aoyu's cultivation became faster and faster.

The strange power in the tender green leaves had been completely integrated into his sea of consciousness, and his spiritual power was quickly catalyzed, as if the ice began to dissolve rapidly, and finally after completely exhausting the strange power, Xie Aoyu found that the spiritual power in the advanced level seemed to have some kind of wonderful connection with his combat power.

This shows that the advancement of spiritual power and the improvement of his cultivation have a complementary effect, and his breakthrough will have a crucial catalytic effect on the advancement of spiritual power.

Cultivation does not know foreign affairs.

Outside Bauhinia Island, he was already seriously ill again, as Zheng Batian said, within three hours, he would definitely return, and he was still with 20,000 people, and all of them were masters of the Fire God Clan, among them, there were two powerful beings who followed Zheng Batian's side with an incomparably thick breath, which made people unable to see through the realm, and the remaining eighth-order war emperors also had nearly ten people.

It can be said that Zheng Batian brought out a considerable amount of elite power of the Fire God Clan this time.

Coupled with the previous 80,000 people, a total of 100,000 people, surrounded Bauhinia Island again, Zheng Batian's face was pale, and his eyes shot a cold glow, obviously when he fled, the summoning badge was destroyed, and the blow brought to him was quite big, if Xie Aoyu was a few points faster, I am afraid that he would definitely die.

Zheng Batian arrived and waved his hand, "Besieging Bauhinia Island, you will kill Xie Aoyu!"
