"Roar!"

Just as the Black Stone Building approached the three-story Black Stone Building, a huge black-winged snake came out of it.

This black-winged snake is more than a kilometer long. Its snake wings have two colors. The color of its body is also a blend of black and gold.

"This is the Yin-Yang Black-Winged Snake!"

After the spirit crab saw this big snake, he immediately exclaimed.

This Yin-Yang Black-Winged Snake is the offspring of a cross between the Yang-Wing Black Snake and the Yin-Wing Black Snake, and is a mutated species.

Although the size of the Yin-Yang Black-Winged Snake in front of me is only ten times that of the adult Yang-Wing Black Snake or Yin-Wing Black Snake, its strength is much stronger than the adult Yang-Wing Black Snake or Yin-Wing Black Snake.

"boom!"

At this moment, Ling Feng's black stone building was connected to the three-story black stone building.

"Boom!"

The black iron pillar at the center of the Black Stone Building slowly rotates and seems to be locked with the three-story Black Stone Building below.

"Bang bang bang..." During the docking process, the Black Stone Tower made clanging sounds.

After seeing this situation, the Yin Yang Black Winged Snake wanted to rush over and stop it.

Ling Feng flew out of the Black Stone Tower, and with a wave of his hand, he released the little white dragon.

"Ouch!"

The little white dragon let out an angry roar, then spit out a white ball of light from his mouth and shot it towards the Yin Yang Black Winged Snake.

The black ball of light spit out by the little white dragon directly hit the Yin Yang Black Winged Snake's neck.

"boom!"

The white light ball exploded, but it was unable to harm the Yin Yang Black Winged Snake.

The Yin-Yang Black-Winged Snake is much stronger than the adult Yang-Wing Black Snake and Yin-Wing Black Snake.

"Eaa?"

When the little white dragon saw this situation, it was stunned for a moment. It didn't expect that the Yin Yang Black Winged Snake was so powerful.

It seemed a little angry, and immediately rushed towards the Yin-Yang Black-Winged Snake. It appeared in front of the Yin-Yang Black-Winged Snake in an instant, and then waved its sharp claws to grab the Yin-Yang Black-Winged Snake's neck.

"Qiang Qiang..." The little white dragon's claws scratched the scales of the Yin-Yang Black-Winged Snake, splashing a lot of fire. Its claws could not break through the Yin-Yang Black-Winged Snake's defense.

"So strong!"

Ling Feng was also a little surprised after seeing this scene.

The adult Yin-winged Black Snake just now had no power to resist in front of the little white dragon, but now when the Little White Dragon faces this Yin-Yang Black-winged Snake, there is nothing he can do.

"Roar!"

The Yin-Yang Black-Winged Snake let out a roar, and it immediately opened its mouth wide and bit at the little white dragon, but the little white dragon immediately dodged.

The speed of the little white dragon seems to be more powerful than its attack.

"call!"

The Yin Yang Black Winged Snake suddenly opened its mouth, and a powerful devouring power appeared, acting on the little white dragon.

"Eaaah!"

The little white dragon flapped its wings desperately, trying to get rid of the devouring power of the Yin Yang Black Winged Snake.

Ling Feng stared at Xiao Bailong, his eyes narrowed slightly, and thought in his heart: "Is this already the limit of Xiao Bailong's strength?"

Ever since Xiao Bailong followed Ling Feng, Ling Feng had always felt that Xiao Bailong was unfathomable. He never knew how strong Xiao Bailong was.

In the past, when the little white dragon took action, its opponents were completely beaten by it.

But now the little white dragon seemed a little helpless in front of this yin-yang black-winged snake.

Ling Feng was not disappointed with Little White Dragon's strength. He knew that Little White Dragon was just a pterosaur that had lived a relatively long time, and that Little White Dragon had not yet survived the Great Emperor's Tribulation and become a Heavenly Dragon.

Moreover, its body is so small that it is normal for it to be unable to defeat the Yin-Yang Black-Winged Snake.

However, Xiao Bailong's strength is already stronger than many super strong people who have opened up the source world.

Seeing that Little White Dragon was in trouble, Ling Feng could no longer stand by and watch. He summoned the Xuanzi Heavy Sword, and then with a gentle wave, the power of Cangyuan Realm was instantly infused into the Xuanzi Heavy Sword.

"Buzz!"

The mountains and rivers pattern on Xuanzi's epee became clear instantly.

A ray of sword energy shot out from Xuanzi's heavy sword, and then turned into a huge stone with a diameter of tens of meters, whizzing towards the Yin Yang Black Winged Snake.

Sword Qi transformed into matter! Ling Feng had already understood this state when he was a powerful person.

At this moment, Ling Feng's cultivation and strength are no longer what they used to be. Using this sword move again is extremely powerful.

The boulder exuded a fierce sword intent and instantly hit the Yin-Yang Black-Winged Snake.

"boom!"

Although the stone with a diameter of only tens of meters is not proportional to the kilometer-long body of the Yin-Yang Black-Winged Snake, the speed of the stone is too fast and the power contained in it is too strong.

The moment it came into contact with the body of the Yin-Yang Black-Winged Snake, the scales on the surface of the Yin-Yang Black-Winged Snake exploded, and its body was also knocked away by the impact contained in the stone.

The devouring power that appeared in the Yin Yang Black Winged Snake's mouth disappeared in an instant, and the little white dragon also seized the opportunity and flew to the spirit crab.

"Roar!"

After the little white dragon returned to Ling Feng, he roared at the Yin Yang Black Winged Snake.

Ling Feng didn't know what Xiao Bailong's roar meant, but he didn't care about Xiao Bailong now because the Yin Yang Black Winged Snake had been angered by him.

"Roar!"

The huge wings of the Yin Yang Black Winged Snake vibrated violently, and its body instantly turned into a strong wind and flew towards Ling Feng.

The laws of space in this ruins are very stable, and Ling Feng even suspects that this place is not the source world, but some broken space from the ancient times.

"Purple Cloud Sword Dragon!"

Ling Feng gently waved the Xuanzi heavy sword in his hand, and countless purple sword energy appeared, forming a thousand-meter-long sword dragon.

"Ouch!"

The kilometer-long Stegosaurus made a loud sound and collided with the Yin-Yang Black-Winged Snake.

"Boom!"

The sword energy on the purple sword dragon was dissipating, but the Yin Yang Black Winged Snake was also blocked by the sword dragon.

Where the purple stegosaurus and the yin-yang black-winged snake collided, violent ripples arose in the space.

If such a collision occurred in the East, the space would definitely be torn apart and turned into chaos.

But in this ancient ruins, even such a violent collision did not tear the space apart.

"The space here is so stable!"

Ling Feng's eyes narrowed slightly and he glanced at the Black Stone Tower.

At this moment, the Black Stone Tower is still slowly rotating, and the docking has not been completed yet.

According to Ling Feng's previous conjecture, the remaining Black Stone Tower should have four floors, because in this way, the nine original powers can be gathered.

But now he only found the third floor here.

"I wonder how much the power of this three-story black stone building will increase after it is integrated with my previous five-story black stone building!"

Ling Feng thought secretly in his heart.

Before this, the power of the Black Stone Tower was comparable to that of the Imperial Treasure, but he did not use it during the Eastern Earth War.

All the purple sword dragons were defeated, and the Yin Yang Black Winged Snake's attack was also neutralized by Ling Feng's sword.

Ling Feng swung his sword again, and the power of Cangyuan Realm in his body was fiercely poured into Xuanzi's heavy sword.

"Buzz!"

Countless sword energies appeared and roared towards the Yin Yang Black Winged Snake.
Chapter completed!
