"Let's go!" Lei Ji shouted immediately, Xiao Yan nodded immediately, and the two turned into long rainbows and were traveling through the broken star world. The goal was very clear, and it was to find the origin of the Thunder of Mixu.

A few days later, Lei Ji and Xiao Yan hid in a canyon and took a break. The most important thing is to analyze their location and the specific situation here.

Rumble!

The violent and low thunder sounds sometimes exploded in the sky. As for the thunder clouds, there were even large areas of thunder clouds gathered, but they were also scattered. The black thunder had no target and contained extremely violent thunder lightning pouring out everywhere. Many huge holes were blown out of the ground. Under the destruction of the black thunder, these broken realm sky was gradually dissipating like a destruction.

After Xiao Yan and Lei Ji entered, they discovered that they were not the only ones among them. Xiao Yan discovered many figures, but Xiao Yan chose to hide his and Lei Ji's aura, so no one noticed them for the time being.

Xiao Yan and Lei Ji's goals were clear, both rushing towards the depths. When they looked up at the sky, they found that the sky above here had long been covered with thick thunder clouds, and it was black, and the huge clouds seemed to be able to touch with a hand.

"Continue moving forward, there are more and more black thunders. If we break in like this, we will inevitably be directly smashed into pieces. We must think of a way." Xiao Yan narrowed his eyes slightly, because the more he went in, the more he walked, the more he seemed to have the intelligence and attacked any object that was moving, until it was smashed into pieces.

Lei Ji frowned slightly, then looked at the black thunder in her palm. When Lei Ji opened her mouth, she swallowed the black thunder and then used her own powerful body as a resistance to forcibly locking the black thunder into her body.

The next moment, Lei Ji's figure flashed out, and even when she came under the dark clouds, she wanted to verify whether her idea was correct.

Rumble!

The heavy thunder clouds poured wildly, and at this moment, a strange scene appeared. When these thunder lights poured out, no thunder light fell on Lei Ji's body.

On the contrary, Lei Ji raised her hand and grabbed a black thunder that fell immediately. Under the suppression of Lei Ji's powerful thunder, just a black thunder could not resist.

Lei Ji fell down and handed the black thunder he grabbed in his hand to Xiao Yan.

"Being part of them can only continue to go deeper." Lei Ji said, as if it were an understatement, but Xiao Yan knew that it was quite difficult to suppress it with Xiao Yan's physical strength.

"I will protect you. If you can't even refine this black thunder, then you won't have to go to the heart of thunder." Lei Ji said, Xiao Yan nodded. He naturally knew this. He did not hesitate immediately, and he opened his mouth and sucked the black thunder into his body.

Saw!

This black thunder suddenly seemed to go crazy and poured out in Xiao Yan's body, causing Xiao Yan's meridians to be devastated in an instant, and the black thunder broke out a blood hole from Xiao Yan's body and ran away in an instant.

"What a powerful destructive power!" Xiao Yan smiled bitterly. Lei Ji didn't say much, but just took action to help Xiao Yan catch another black thunder, and Xiao Yan did not give up. He continued to inhale the black thunder. While the injuries in his body were recovering rapidly, the black thunder was sweeping wildly. This time, Xiao Yan knew that it was obviously difficult to suppress and refine without using the power of the Heart of Flame.

The two have different forces, but both are still extremely violent energy. The flame range is wider, and the thunder is stronger, and each has its pros and cons. In short, flame and thunder have the same effect. It is undoubtedly of great help to Xiao Yan to control the flame.

The second black thunder, Xiao Yan, was forcibly refined several days later, and became a part of his body. Most of the reasons for his success were due to the help of the three flame hearts. Only by using violence to fight violence is more direct and effective.

After Xiao Yan successfully refined one, Lei Ji did not ask Xiao Yan to set off immediately, but continued to capture the second and third paths for Xiao Yan... until the tenth path, Xiao Yan had no complaints, because while refining the black thunder, Xiao Yan's physical strength was also increasing wildly.

Ten black thunders merged into Xiao Yan's sea of ​​thunder. This black thunder is equivalent to one hundred square meters. When Xiao Yan refined the ten black thunders, the two thousand square meters of thunder sea in his body came to three thousand square meters!

Of course, the reason why Xiao Yan was able to successfully refine them was that he relied heavily on the Heart of Flame. Of course, the Heart of Flame is one of Xiao Yan's powers, so it is not surprising that he used the Heart of Flame to suppress and refine them in this situation.

"Continue to set out. During this period, you should not stop refining. Refining as much black thunder as possible. Even if you cannot obtain the Mixu Tianlei in the end, you will also use this to improve your physical strength. At least it will not be a waste of time." Lei Ji said. She felt the power of the Mixu Tianlei, so she also believed that the possibility of Xiao Yan being able to refine it into her own use was slim.

Xiao Yan nodded, and the two continued to set off on the road and continued to rush towards the depths. The lightning continued to pour out, but no black thunder hit them, as if at this moment, they also became part of the black thunder.

However, not long after, the black thunder clouds at the far end rolled back, forming a huge black cloud vortex, in which countless thunder lights flashed wildly.

"Thunder pulp!" Lei Ji said in surprise.

Xiao Yan also saw the changes of the thunder clouds and let out a cold hiss. This scene was once seen in the place where the Red Star sealed Lei Ji, and it contained a magnificent thunder power.

But the thunder slurry in front of me was even more terrifying, and it poured down from the air. From a distance, it looked like a waterfall falling from the sky, forming a sea of ​​thunder slurry below it, spreading to the end of the gaze.

Obviously, Xiao Yan and the others are gradually approaching the central area.

At this moment, the moment Xiao Yan and Lei Ji entered the place, several figures appeared at the far end, and they were also rushing towards the depths. When they saw these figures, Xiao Yan was also slightly shocked.

I never expected that everyone else would come here. At the same time, the figure led by the group turned his head and looked towards him and Lei Ji.

After Xiao Yan came, he did not use his soul power to hide his breath, because Xiao Yan never expected that there would be someone here to arrive. He was calm and calm when he saw their figures. He probably used the same method, and his body contained black thunder.

Looking from afar, there was a huge palace standing among the thunder slurry like a black iron beast.
