No matter how far Xuan Lei has advanced and what kind of power he has, there is one thing that can never be erased, and that is that it is Xie Aoyu's power.

Since it is its own power, it is naturally connected.

It's just that the previous thunderball didn't know if it was because of its advancement, and it was completely disconnected from Xie Aoyu, so that Xie Aoyu couldn't even feel its existence, as if it disappeared out of thin air, and now it can produce a first-line force counterattack when it encounters danger, or under the oppression of the tenth-order war emperor power of the natural disaster clan, which shows that its advancement has reached the point where it is about to end.

Xie Aoyu tried to sense it again.

A hint of vagueness passed from the thunderball, very faint and weak, as if Xie Aoyu and it were connected through a silk thread.

The connection was weak, but Xie Aoyu could vaguely feel how strong the power of the thunderball was.

"Crackle, crackle, crackle......"

The thin golden lightning around the thunderball flickered, and they were also releasing their own power, Xie Aoyu used his heart to determine the power of this golden thunderbolt.

At the beginning, the attack power of the tenth-order war emperor of the Heavenly Calamity Clan against Xie Aoyu was almost equivalent to the power of the sixth-order war emperor, after all, Xie Aoyu was only a fourth-order war emperor, although his Holy Emperor practice technique could cover his strength, but after the power was exerted, it would be difficult to escape the perception of a tenth-order war emperor, so he only needed to exert the power of the sixth-order war emperor to bombard Xie Aoyu, not to mention the situation at that time, it was impossible for him to target Xie Aoyu too much, which would make the four dragon scales swallow more of his soul power.

Xie Aoyu couldn't sense how powerful the thunderball itself was, but he could judge the power of the golden lightning released around it.

A line of strength comparable to that of a fourth-order War Emperor.

With such a quantity, fused, it can completely oppose the power of the sixth-order War Emperor.

This is just a little bit of power emitted from the thunderball, and the trace of golden electric light is only about the same thickness as a silk thread.

So how powerful is the whole Thunderball?

Xie Aoyu tried to control the thunderball, all he could do was to attract the thunderball through the faint connection that looked like a silk thread.

As a result, after several consecutive tests, the thunderball was not moving.

Xie Aoyu is not discouraged, such a connection, in the face of the thunderball, if it can trigger its changes, it is not normal, since the thunderball is not good, then go and experiment with the trace of golden lightning, if they can be integrated, it is also infinitely powerful, it is comparable to the power of the sixth-order war emperor.

He tried to manipulate the golden lightning bolts.

As soon as his mind moved, the golden lightning that was as thin as a gossamer made a crisp thunderclap, and under Xie Aoyu's control, it slowly spread outward, but when the golden lightning was about to break away from the thunderball, a trace of pulling force came from the thunderball, and it was pulled back.

This change made Xie Aoyu a little stunned.

He couldn't pull out the thin line of golden lightning like a gossamer, and he was a little unwilling to pull that line of golden lightning again.

The result is still a failure.

It's as if the golden lightning bolts around the Thunderball can't leave the Thunderball.

This made Xie Aoyu a little puzzled.

It stands to reason that this shouldn't be the case, especially since Xuan Lei in the advanced stage had sent out a line of golden lightning before, and the situation at that time was re-filtered in Xie Aoyu's mind.

Memories over and over again.

Gradually, Xie Aoyu found a problem, it seemed that the situation at that time coincided with the Thunderball advancing to a certain level, releasing these small golden lightnings, and the attack of the Tenth Order War Emperor of the Heavenly Calamity Clan happened to arrive, so he counterattacked.

"It can't be such a coincidence, right?" Xie Aoyu muttered.

If it's a coincidence, then he really can't control it.

But intuition told Xie Aoyu that such a coincidental thing always felt unreal, and there must be something wrong with it, but he didn't figure it out.

Xie Aoyu didn't recognize the coincidence, so he continued to reminisce.

The situation is constantly recalled.

Space power?

Xie Aoyu's attempt to manipulate the spatial power to stimulate the golden lightning on the thunderball was also ineffective, so he turned to using battle qi instead.

At that time, he was at the moment when he pushed the war spirit to its strongest.

The battle spirit is awe-inspiring, and the whole body is circulating.

Xie Aoyu's fighting intent also came out unnaturally, and immediately attracted the attention of the other forces around him, and they all turned their heads to look.

That fierce battle intent made Xie Aoyu's whole person look like a divine knife out of the sheath, so that everyone couldn't help but be on guard to prevent being attacked by Xie Aoyu.

The stronger the fighting spirit, Xie Aoyu found that the thunderball seemed to be stimulated by some kind of stimulation, and it actually trembled, and the subsequent change was that the small golden lightning began to converge, condensing into a line of golden light, surrounding the thunderball, at first glance, it was extremely similar to the golden divine dragon composed of four dragon scales, if it were not for its electric light, Xie Aoyu would be difficult to distinguish the difference between them.

"Is it the change caused by the power of the four dragon scales?" When Xie Aoyu saw this scene, he recalled the golden divine dragon that appeared on the four dragon scales.

At that time, it was the power of the tenth-order war emperor of the Heavenly Disaster Clan, Xie Aoyu was able to observe the movements of the golden divine dragon, but because it was just a move, it had not exerted its power at all, Xie Aoyu felt that it had not yet launched an attack, and the advanced Xuan Lei released golden lightning, and now it seems that it is not the case at all, the real reason should be that the golden divine dragon with four dragon scales cooperated with his own battle qi to urge, revealing a monstrous battle intent, so that the thunderball reacted and released the golden lightning.

When Xie Aoyu saw this, he casually used a triple space superposition to prevent outsiders from seeing it.

That's when he took out four dragon scales.

After instilling the battle qi, the four dragon scales floated in the air, and a golden divine dragon appeared on the surface, with teeth and claws, Xie Aoyu said: "When I fought with the tenth-order war emperor of the Heavenly Calamity Clan before, he attacked me, was it the golden lightning around the advanced Xuanlei that you induced?"

The golden dragon nodded slightly.

"Sure enough, it's you!" Xie Aoyu's face became solemn, "How can you control my power?!"

This is what Xie Aoyu really cares about, and even worries about.

Your own power can be controlled by others, which is more difficult to accept than anything else.

The golden divine dragon hovered in the air and let out a grand voice, "Your thunder and lightning power contains a considerable part of my soul power, and before it is completely advanced, I can already use some soul power to simply release its first line of power." ”

Xie Aoyu, who was originally a little worried, and even angry, calmed down.

He naturally knew that because of the original Xuanlei Advancement, everything was closely related to the four dragon scales, and it was the result of the battle between the dragon scales and the golden lightning that gave birth to the mystery of thunder and lightning, and the golden lightning was integrated into the Xuanlei, and as a result, the golden lightning also pulled the soul power in the dragon scales into it, which caused the current situation of Xuanlei Advancement.

"How much power can you control?" Xie Aoyu said.

"It's just a glimmer of light on the periphery. The golden dragon replied.

Xie Aoyu was stunned and said, "So little?"

"Less?" The golden divine dragon stared at Xie Aoyu with wide eyes, as if looking at a monster, "Do you know what kind of existence your Xuanlei is after it is advanced? When you can control it, you will know that with the advanced thunder and lightning power, you can kill the tenth-order War Emperor with one finger, and if I can control it so much, it is already the limit of my infinite soul power!"

Xie Aoyu's eyes were round, and he said in shock: "What did you say? After Xuan Lei advanced, he could kill the Tenth Order Battle Emperor at will? What kind of realm is that?"

The Golden Divine Dragon said: "I don't know, unless my soul power is increased by two to three times, I will be able to know some of the memories left by the Ancient Holy Emperor, and I know that the Ancient Holy Emperor left behind the secret method of creating the Nine Great Sacred Tablets, and then creating the Nine Great Dragon Scales, so as to produce my true purpose." ”

It also requires two to three times the soul power!

Xie Aoyu was speechless.

With his help, how much soul power has the four dragon scales absorbed? Just in the trap set by Baili Mou, the soul power devoured is probably comparable to the soul power of a tenth-order war emperor, plus the soul power absorbed by himself before, as well as all the soul power of the ancient demon clan people absorbed, and some of the power of the tenth-order war emperor of the natural disaster clan, he even suspected that the strength of the soul power alone, I am afraid that the soul power in the four dragon scales has exceeded the limit of the tenth-order war emperor.

If you increase it two or three times, how much soul power will it take?

"You can't devour the soul power yourself, you still need to use the Wild Thunder Beast Soul, how can you meet your requirements? Xie Aoyu said.

"Only by attaining sufficient soul power can I obtain all the memories left by the Ancient Holy Emperor and know what the purpose of my existence is. The golden dragon replied.

Xie Aoyu said: "Then you don't feel it at all, I don't know what the Ancient Holy Emperor wants you to do?"

The golden divine dragon said: "I don't know, I just know a little rough information, that is, I want to complete the mission left by the Ancient Holy Emperor, and I am too weak now." ”

What the hell are you going to do? It takes such terrifying power.

For the ancient Holy Emperor, Xie Aoyu was also hazy, maybe only when the colorful phoenix recovered and got all the inheritance memories could he know some of the inside story.

Since he couldn't figure it out, Xie Aoyu didn't ask anymore, he was more concerned about how much power he could control, and said, "Can I control the ray of golden lightning released by this advanced Xuan Thunder?" Or can I only rely on you to be able to exert the power of that ray of golden lightning?"

"You can do it yourself!" replied in the affirmative of the Golden Dragon.
