On this mountain range, Ying Fei Fei is not afraid to expose all his strength, "Bang Bang Bang" Ying Fei Ying Fei in turn stimulates the other four source qi of fire, earth, wood, and water, at this moment, his whole body, the five systems of source qi violently tumbled alternately, and the whole person was suddenly full of majesty, unstoppable.

The "Ang !!" rhinoceros beast was naturally not to be outdone, and roared loudly towards Ying Fei, and this echo was also resounding in the sky, making people a little deafening!

The rhinoceros was already hot-tempered, and Ying Fei had already provoked it with a punch before, and now he was mobilizing his source qi in front of it, which was undoubtedly provoking the rhinoceros beast.

The front horns of the rhinoceros are scavenged into the ground, and a rich brown earth-based source gas gradually gathers on the rhino horns.

"Sword Qi!" "Ang!", Ying Feifei struck with all his strength, instantly draining the source qi in his body, and the rhinoceros beast also rushed towards Ying Feifei with all his strength.

"Boom!" The source qi collided, the sword horn exerted force, and the pool water was stirred up ten meters high, and then the source qi fluctuated, and the collision center between the extraordinary and the rhinoceros beast spread out, and it stirred up layers of water waves!

"Wow!", Ying Feifei was directly pushed back by the source qi that exploded, and in terms of the richness of the source qi, even if Ying Feifei was fully open, he still lost to the Xuan-level high-level rhinoceros beast.

However, it should be extraordinary, "Sword Qi, Shocking!", after the source qi collided, it broke through the rhinoceros beast's earth-based source qi and slashed directly at its horns and body.

The horns of the rhinoceros beast are equivalent to the weapons of the fourth grade, which are extremely hard, and they should still have left a sword mark on it, and the thick skin on its back has been directly cut through a one-meter-long opening, and blood is gurgling out.

Although the rhinoceros also suffered a lot of losses, however, Ying Fei did not hurt its roots, and these wounds were not fatal.

"My source qi is basically exhausted, it seems that I still underestimate its defensive ability!", Ying Feifei still overestimated himself, the five series of source qi is fully open, and the amount of source qi released in an instant is not increasing exponentially.

After the rhinoceros was in pain, it was still a little afraid, after all, its most confident animal skin had been torn open, but after seeing that Ying Fei's whole body source qi gradually faded, the rhinoceros beast slammed towards Ying Feifei again.

"Ang!!", at this moment, the right side of the rhinoceros beast instantly exploded with source qi, and then a whole body was dark, seven meters long, three and a half meters high, with a pair of five meters long bat wings, dark and deep eyes, two beast horns that had just emerged, sharp fangs, slender front claws, and the whole body was also wrapped in explosive source qi lightning, which looked extremely domineering!

"It seems that Xiao Hei has grown a lot bigger! And now its usual mind is equivalent to that of a three-year-old child!", Ying Feifei looked at Xiao Hei after the transformation, and his heart was full of relief, he watched it grow up by itself!

After seeing a source beast of comparable size appear beside him, the rhinoceros beast gave up the non-threatening Ying Fei, turned around, and confronted Xiao Hei.

The rhinoceros beast is a high-level source beast of the Xuan Rank, and it is also the best in it, but from Xiao Hei's eyes and posture, it shows nothing but disdain and contempt.

Even if Xiao Hei brought a strong aura of danger to the rhinoceros, the level of the rhinoceros on the bright side was higher than that of Xiao Hei, and as a high-level source beast of the Xuan Rank, it also had its own pride, so it would not choose to flee without a fight.

After a few seconds of confrontation, the rhinoceros beast chose to take the lead in attacking, and rushed towards Xiao Hei, Xiao Hei's whole body did not have obvious source qi fluctuations, only a layer of black gas, but it should be felt extraordinarily, that layer of gas, compared to any source qi on the barren continent, is much stronger.

Seeing the rhinoceros rushing wildly, Xiao Hei didn't dare to be careless, it immediately flapped its wings and flew off the ground, and the rhinoceros jumped directly into the air, breaking several big trees before it was able to stop.

"Ang, Ang, Ang!" The rhinoceros beast was a little annoyed by this play, and with a force under its feet, it jumped up directly and chased Xiao Hei in the air!

"The Xuan-level high-level source beast is equivalent to a human Douyuan period martial artist, and it can fly in the sky for a short time!, but for the rhino horn beast, the consumption of the sky must be extremely large, it seems that it has fallen into Xiao Hei's trap!", Ying said in his heart.

Sure enough, Xiao Hei, who has wings, has a great advantage in both speed and consumption.

After a while, the rhinoceros fell panting, and Blackie spun around above it, provoking it.

The rhinoceros took off again, but this time in less than ten seconds, it fell, and had to roar at Blackie unconvinced.

Seeing that the time was ripe, Xiao Hei suddenly increased his flight speed and attacked the rhinoceros, the bulky rhinoceros was obviously physically exhausted, and Xiao Hei's claws were even sharper, leaving a striking blood mark on its skin.

This can completely enrage the rhinoceros, and it immediately distances itself, and a fist-sized and extremely striking brown ball of light suddenly gathers on the rhino horn.

"Although it is not as large as the amount of source qi just now, it is obviously much richer, is this the source qi mass that only the Douyuan powerhouse can condense? I don't want this beast to directly compress the source qi and then launch the source qi mass to attack! Xiao Hei, don't be hit!", Ying said in his heart.

Seeing this, Xiao Hei didn't avoid it, only to see that above its claws, there was also a black source qi mass condensed, and its coercion was equally amazing.

"This is the difference between high-level source beasts, they can also use the beast core and the surrounding source qi to launch source qi attacks like human martial arts!"

"Boom!" Xiao Hei and the rhinoceros threw out condensed source qi light balls at the same time, and then collided directly, and immediately saw the rhinoceros beast's brown source qi light cluster, suppressing Xiao Hei's black source qi and gradually retreating.

"No! It's not that simple!" After lasting for ten seconds, Ying Feifei noticed that Xiao Hei's black source qi gradually devoured the rhinoceros beast's brown source qi, and then flew towards the rhinoceros beast.

"Boom!" Because the source qi collided just now, the trajectory of the light cluster was shifted, and Xiao Hei's black light cluster hit five meters next to the rhinoceros beast, and then exploded.

The rhinoceros beast's huge body was directly swept away several meters away, and then hit the stone wall, and after a burst of black smoke, the ground hit by the small black source qi directly appeared a black ground that emitted the smell of corruption.

"Xiao Hei's black source qi actually has the effect of devouring corruption!!It's really amazing!", Ying Fei lay on the edge of the pool and sighed.

After a few seconds, the rhinoceros struggled to stand up, this time it hurt it, and it had no choice but to reluctantly roar a few times, and chose to flee, but for fear of Xiao Hei's pursuit, it panicked and ran away, breaking several large trees along the way.

Seeing the rhinoceros leave, Xiao Hei changed back to his usual fist-sized appearance and flew to the edge of the pool, which should be extraordinary.

And Xiao Hei was also a little tired, pulled his head, and hid in Ying Feifei's space ring, and at this moment, Ying Fei saw that the rhinoceros beast was driven away by Xiao Hei, and he didn't have time to put on his clothes, so he finally couldn't hold on and passed out.

"...........Whoa, whoa", the water crashed against the cliff, and the regain consciousness should be extraordinary, feeling like he was stranded on the shore, he opened his eyes and found that the surroundings were bright, and he was in a cave!
