After walking through the strange crystal mountain forest, Roy's face suddenly opened up, and a Gobi desert appeared in front of him, and there was a high mountain in the distance.

There were no animals or cities around, and the big black bull swayed vertically towards the mountain.

On the desolate Gobi Desert, the boy was lying on the back of a cow, drinking wine, humming a ballad, and being at ease, the big black cow also learned Roy's song, he was also a very high immortal-level pure-blooded demon beast, and it was still very simple to learn some songs, but a cow sang Xintianyou, which was a little too weird.

Two days have passed, the mountains seem to be in front of you, but in fact, there are still about a hundred miles, there is no trace of biological survival on the Gobi Desert, and it is not suitable for any living creatures to survive, the stones under their feet are very hard, even ants do not burrow and nest here, let alone other creatures, Roy did not even see a bird.

"The ground here is very hot, so there's a volcano down there, right?" The big black bull took a closer look at the bottom and found that many of the stones here are not actually stones, but metal, very soft metal, or yellow, Roy looked at it, and the corners of his mouth couldn't help twitching, the stones on the ground are gold nuggets at all!

As long as you take it back and dissolve it a little, you can make pure gold, and after continuing to walk forward for more than ten miles, the ground is already full of gold ore, and you can already see the gold ore exposed on the ground, if you let mortals know, I'm afraid you will be crazy, you will really go crazy, there is gold everywhere, this temptation is not ordinary!

It's just that when he arrived here, the big black bull's face changed, and he felt that the immortal energy was disappearing, as if the immortal world was moving away from them!

Roy probably knows the facts, they seem to have entered a bizarre ancient world again, Roy is speechless, he always crosses for unknown reasons, I don't know what's going on, this time, I also brought a cow to cross together, it's really... Alas....

The big black bull wanted to turn back, Roy saw his concerns, and said: "If you want to go back, go back, my life, that's it, you go!" ”

The big black bull said in a solemn tone: "I know that you have an extraordinary background, but I really don't dare to leave the fairy world, so I will leave first, goodbye, goodbye!" ”

When Roy jumped down, the big black bull turned his head and ran wildly, and the one who ran was called merrily.

However, suddenly, Roy saw that the earth in the distance had collapsed, countless lava surging underground, and in the sky, the clouds were thick, and the purple and cyan thunder kept falling, and the big black bull fell into the underground magma, and countless thunderbolts struck him, making it even darker.

"Help!" The big black bull begged Roy for help, he almost cried, this is a disaster that is not justified at all!

Roy frowned, he felt that the power of those thunders was tricky, but he couldn't watch him die!

As soon as he gritted his teeth, Roy rushed over, using his chaotic gas to turn into chaos thunder, guiding the thunder in the sky to other places, as for the magma under his feet, just ignore it, people who can fly, what magma do they care? But Roy was wrong, the fire on the ground was not an ordinary fire, the temperature was extremely high, the power was huge, not inferior to the sky and thunder, stepping on it, Roy used the Chaos Fire Technique to barely step on it without being injured, however, he felt that he couldn't last long.

Rushed to the clouds, scooped up the big black bull, and ran for his life like crazy, the chaos escape technique was used to the limit, Roy felt that the power of the thunder was increasing, although he had tried his best to guide it, but his body was still numb, and after a while, it should be a deadly thunder.

Rumble!

A thick thunderbolt fell, actually filled with chaotic qi, ignoring Roy's defense, and slashed straight at his body, staggering him, and almost fell directly, as for the big black bull that he fell in his hand, because his horns have an insulating effect, so the impact was not so big, but after this time, it also became more out of breath and less intake.

The fire burned Roy's boots from his feet, and soon, half of his pants were left, and his whole body was charred black.

When Roy ran out of the range of the magma, the thunder in the sky stopped slashing him, but the magma under his feet was still spreading towards him, and it was extremely fast, and Roy's full speed was only a little faster than the speed of the magma spreading.

"This is the circle of damnation!" Roy yelled, running faster and faster, and he didn't know how long the thunder and fire behind him were going to chase him.

After running for more than 200 miles, Roy found that the speed of the thunder chasing behind him had slowed down, so he ran even faster, until he ran to a beautiful place and completely felt the earth-destroying fluctuations, Roy stopped.

At this time, Roy has already determined one thing, he can't stop at all, it seems that everything is doomed, he has to travel endlessly in countless worlds, this is his own life, and it is quite interesting, especially after following an unlucky guy behind him.

The big black bull exuded the aroma of beef, and there was only a trace of life left in his body, and he was almost completely dead.

However, this is also his opportunity, after carrying such a thunderstorm, his bloodline will definitely undergo transformation, and his roots and strength will definitely improve a lot!

Roy crossed a lot of chaotic qi to the big black bull, and after absorbing the chaotic qi, the outer shell of the big black bull quickly turned into dust and dissipated, and it didn't take long for a new black bull to appear, but it was very small, like a newborn calf, and the horns on the head also turned cyan, which looked extremely extraordinary.

"Chaos Thunder Fire Cow." The big black bull smirked and said: "I have transformed into a chaotic bloodline, I have become a chaotic creature, a chaotic thunder and fire cow!" ”

There is thunder between the horns of the big black bull, and the four hooves are suspended in the air with the flames, which is majestic and looks extremely extraordinary.

Roy nodded and smiled: "This is a bit of a look, and it won't be so easy to hang up with me in the future, hehe, not bad!" ”

The big black bull was silent for a moment and said, "Maybe it's really like this, maybe it's because of your luck that I will transform so smoothly." Perhaps, I am destined to follow you and become your mount's bull. ”

The lines of fate flashed, and Roy grinned and took off the ring on his hand and made a hole in the big black bull's ear!
