After listening to Lin Dong and Xiao Mink's explanation, Lin Dong also understood that Xiao Yan wanted to continue to keep up with him, and it was not something that could be solved now, so he could only take this matter to heart and help Xiao Yan when he had a suitable opportunity in the future.

In the next two days, Lin Dong and the others found the lair of the Lei Yuan Crystal Beast, and at the same time "sent" the Liu family, who couldn't open their eyes, and harvested another high-grade spirit treasure, and then began to wait for the Lei Yuan Crystal Beast to advance.

......

"Boom!"

The sky was cloudy, and the razer was struggling to break free from the clouds.

"The Thunder Source Crystal Beast is going to advance!"

Lin Dong said softly, seeing this scene, he was still very shocked in his heart, this thunder is not a natural phenomenon, but caused by the thunder source crystal beast, such a ability is really magical.

After Lin Dong subdued it, it would be much more convenient to borrow it to cultivate the Xuanri Thunder Body.

"Let it advance to the next level before it passes."

Lin Dong didn't want to interfere with the promotion process of the Lei Yuan Crystal Beast and stop Lin Dong who was preparing to pass.

The Lei Yuan Crystal Beast is now a Qi Creation Realm master, and after being promoted, it will be the Creation Realm, but there will be a period of weakness, but even if it is not weak, it will be easy for Lin Dong to crush it.

"Roar!"

As the thunderclouds in the sky churned more and more violently, suddenly, in the huge mountain, there was also a sudden sound of an extremely loud roar, this roar was extremely strange, like a lion's roar, like thunder, mixed together, mixed with the thunder in the sky, spread far away.

"Boom!"

When the thunderclouds accumulated to their peaks, a ray of thunder broke free from the clouds and struck towards the mountains and forests below.

A giant beast leapt from the ground and rushed towards the thunder.

The giant beast, the whole body is dazzling silver, the thunder light is constantly circulating on the surface of its body, and the slightest arc explodes from time to time, causing fierce energy fluctuations, the skin of this giant beast is not ordinary fur, but similar to a kind of crystal armor, which looks very strange.

The thunder source crystal beast stepped on the pillar of light, its four hooves were like a mountain, revealing calmness and heaviness, with thunder wings on its back, and in its hideous mouth, it was even more thunder flickering, as if it could shoot out a powerful thunder light when it opened its mouth.

Boom!

The thunder light bombarded the body of the Thunder Source Crystal Beast, directly knocking it to the ground, raising a puff of black smoke, and the Thunder Source Crystal Beast suffered some injuries, but it didn't have much impact.

Immediately after that, another thunderbolt thundered, and the Thunder Source Crystal Beast stood up from the ground and headed towards the thunder light, but the result was still the same, and it was blasted to the ground.

Time passed slowly, and the thunderclouds slowly weakened.

"This Thunder Source Crystal Beast is really powerful, and there are probably very few demon beasts of the same level that can defeat it." Lin Dong said.

"Cut, even if Master Mink is a small realm lower than him, he can defeat it." The little mink appeared on Lin Dong's shoulder and said arrogantly.

"Your Heavenly Demon Marten is one of the four overlords of the Demon Domain, how can ordinary demon beasts compare with you, this Thunder Source Crystal Beast is already very extraordinary."

Now Lin Dong is of course the status of the Heavenly Demon Marten in the Demon Beast World.

"Evolution has reached the most critical time, whether it can succeed depends on whether it can withstand this last thunder." Lin Dong said.

"This thunder light is too big, I don't know if the Thunder Source Crystal Beast can carry it."

Lin Dong's face was a little stunned, this last ray of thunder light was almost the thickness of a bucket, and the small thunder he had absorbed when he had cultivated the Great Sun Thunder Body before was nothing compared to this.

Boom!

The bucket-thick thunder light bombarded the body of the thunder source crystal beast, knocking it down to the ground again, this time directly forming a large crater, and the forest in a radius of kilometers was destroyed by the thunder.

Even if Lin Dong and the others were far away, they could already clearly see the situation in the pit, and the Lei Yuan Crystal Beast at this time was lying in the pit, its whole body was scorched, and the crystal armor was also cracked one after another.

But if you look closely, you will find that under this layer of charred crystal armor, a new crystal armor has grown again.

"Looks like a success! Big brother, let's go over. ”

"Wait a minute."

Lin Dong's spiritual power sensed that there were a lot of formations nearby, and the Qi Creation Realm demon beasts were already ready to move, without the early clearance of the Liu and Di families, the attraction of the Lei Yuan Crystal Beast's Lei Yuan to the demon beast was no less than that of the Heavenly Treasure and the Earth Treasure, and they were all waiting for the opportunity for the Lei Yuan Crystal Beast to be weak.

The Lei Yuan Crystal Beast also sensed the movement of the demon beasts, and after recovering for a while, it roared loudly, and at the same time released the coercion of its first entry into the Creation Realm.

This coercion scared away all the demon beasts in the Formation Realm, but there were still three demon beasts in the Qi Creation Realm that stayed and watched.

"It's so majestic, and it's barely enough to be my mount! Second brother, you go and deal with the three-headed demon beast, and I'll go and subdue the Lei Yuan Crystal Beast. ”

"Good!"

Lin Dong flew to the top of the big pit and looked at the Thunder Source Crystal Beast condescendingly.

"Today you have a relationship with me, I wonder if you are willing to follow me?"

"Roar!"

The Thunder Source Crystal Beast also yelled in the face of Lin Dong's question, although Lin Dong couldn't understand it, but from its expression, it could be seen that the meaning it wanted to express, the Thunder Source Crystal Beast would never succumb to humans!

"Really, don't you want to?"

Lin Dong landed beside the Thunder Source Crystal Beast, suppressed the Thunder Source Crystal Beast with the spiritual coercion of the Heavenly Rune Master, and then stroked its smooth crystal armor and asked again.

"Woo!"

Lei Yuan Crystal Beast didn't expect Lin Dong to be so strong, feeling the terrifying spiritual coercion, he didn't dare to move, he could only let Lin Dong touch it, and his mouth showed a weak voice.

"If you want to, nod your head, if you don't, shake your head." Lin Dong said.

After listening to Lin Dong's words, the Lei Yuan Crystal Beast nodded and shook his head again.

"What do you mean by this, willing to follow me, but still on condition?"

"Big brother, the little mink said that it came to communicate with the Lei Yuan Crystal Beast to ensure that it was willing to surrender!"

Xiao Mink was in a hurry to express himself, and kept urging Lin Dong to solve the demon beasts, and when he returned to Lin Dong's side, Lin Dong did not save Yuan Force, and directly destroyed the three Qi Creation Realm demon beasts with a 10,000 overlapping seal, leaving Xiao Yan to clean up the battlefield.

"Come on, mink." Lin Dong didn't understand the language of demon beasts, so he couldn't communicate efficiently, so he could only guess.

After a while, the little mink persuaded the Lei Yuan Crystal Beast.

"Brother Lin Dong, the Thunder Source Crystal Beast hopes that you don't use its Thunder Source to absorb and cultivate, which will curb its realm ascension, I have already agreed, which also shows that the eldest brother has already broken through the Nirvana Realm, and I can't look down on its Thunder Source, in addition, I also taught it an energy cultivation method of the beast clan, presumably the strength improvement can be faster, and help the eldest brother deal with some troubles."

"Well done, mink."

Lin Dong touched the Lei Yuan Crystal Beast that took the initiative to come up, turned over and rode on.

"Big brother, shouldn't you give it a name?" Lin Dong said.

"It's a thunder source crystal beast, let's call it Xiao Lei." Lin Dong thought for a moment and said.

"Roar! Woooooo

Lei Yuan Crystal Beast roared dissatisfiedly, obviously disliking the name, but there was nothing to be done about Lin Dong.

"Xiao Lei and Xiao Yan are more compatible, and the names of the two brothers' mounts must also be unified in style."
