Under the mottled sun, the magnificent Tongtian sword tower entrenched in this heaven and earth like an ancient fierce beast. The looming light curtain flashed terrible pressure, which almost solidified the air within hundreds of feet. Su Bai's eyes stared at these light curtains directly, and a look of consternation spread from his eyebrows: "only my sword formula..."

This familiar wave made Su Bai's feet stop in the air, and even went straight to Tongtian sword building.

"What's the matter with this guy? Does he still want to fight the Tongtian sword building? The emperor remembers that the ants in the Chu song can't break the seal outside the Tianjian building with all their efforts." the two winged blood dragon whispered: "junior brother, these seals outside the Tongtian sword building are not as simple as the seal of the sword tablet. If you break through it forcibly, you will be rebounded by the seal..."

"Why does this guy do things regardless of priorities? I hurt my strength to break the seals of these sword tablets. If he somehow touches the seal of the sword building and gives his life here, I won't waste my mind for months." Taotie's voice was a little hasty.

"I know!"

More than a hundred feet away, Su Bai could clearly hear the low roar of the two winged blood dragon. As he moved forward, he could also feel the repulsive force penetrated between heaven and earth and tried to stop him from moving forward. Especially when Su Bai stepped into this area, the looming light curtain burst out in vain.

Boom!

A terrible and incomparable tearing force suddenly surged on the light curtain. The aura between heaven and earth was directly torn by the outrageous tearing force. Dimly, ripples could be seen rippling on the light curtain.

The pressure between heaven and earth suddenly increased, Su Bai's eyebrows slightly wrinkled, and the only self sword formula in his body was running uncontrollably and frantically at the moment. The sword Qi in the Dantian sword sea immediately poured out on Su Bai's limbs and bones like a torrent.

Su Bai's thin figure looked like a sharp sword. Then, in the eyes of the two winged blood dragon and Taotie, Su Bai's right hand pressed against the light curtain, "shit, your senior brother is crazy. It's death!"

"Worm, stop your elder martial brother. I tried to break the seal at the beginning, but in the end, I didn't even break the seal, but almost told him there." Taotie was worried, but he couldn't imagine how Yisu Bai's weak body could withstand the rebound of the seal.

The two winged blood dragon wanted to cry without tears. The huge wings vibrated gently, and the huge body burst out immediately.

However, at the moment when the two winged blood dragon swept out of Cambridge, his body stopped in mid air. He looked at the scene in front of him unbelievably. He saw that the light curtain appeared as if it were in vain. Su Bai's right hand explored without any damage, "Damn it? What's going on?"

The ripples rippled out of Su Bai's fingertips, and Su Bai immediately felt like putting his right hand into the water curtain.

"The breath flowing on this light curtain is very similar to the breath fluctuation brought by the cultivation of weii sword formula..."

Su Bailu thought deeply and looked up at the Tongtian sword building in front of him. The sad blood light made the Tongtian sword building look more mysterious. "After I started the only sword formula, the oppression between heaven and earth was obviously relieved..."

Su Bai waved his big sleeve in vain, and his eyes showed determination. Suddenly, his whole body was moving with a cold sword light. Almost in the blink of an eye, Su Bai just walked up to this light curtain.

The cold touch came from his skin, and Su Bai walked through the light curtain almost without any obstacles.

"Sure enough, as long as I run the only sword formula, these seals are like nothingness to me." Su Bai murmured softly, but there was a little ecstasy in his calm eyes. Doesn't that mean he can walk to the sky sword building safely.

One, two, three... Six... Twelve

At the moment when he walked out of the last light curtain, Su Bai suddenly appeared in front of Tongtian sword building. An ancient vicissitudes spread from Tongtian sword building, making this piece of heaven and earth feel lonely.

The style of the sword tower is very simple. The gate of the sword tower is closed, and there are two huge statues of fierce animals on both sides. The amazing evil spirit radiates from it, rippling and depressing.

Staring at the two fierce animal statues, Su Bai was slightly moved and his body was tight.

Click!

A slight sound suddenly sounded in Su Bai's ears. Su Bai looked up and saw that the closed door seemed to be pushed away slowly by a pair of invisible hands.

There was only one crack, but Su Bai felt very cold after the crack. He didn't know how many terrible killing opportunities there were.

After a moment of silence, Su Bai walked towards the Tongtian sword tower. He knew that there might be unknown killing opportunities in the sword tower, but he had come to this point. With his temperament, he was unwilling to give up. In the near moment, a very strange whine suddenly rang through the world.

Su Bai's eyes narrowed and stared straight behind the gate, where the sound sounded. In the endless darkness, he actually saw a huge shadow rolling and surging.

Su Bai took a breath of cold air and felt creepy.

"Double only my sword formula, Tiangang nine levels, can go up to the fourth floor of the sky."

The hoarse and incomparable voice sounded slowly from the huge virtual shadow, and at the moment when the voice sounded, the huge virtual shadow retreated into the darkness like a tide.

Su Bai looked at the scene in disbelief, clenched his hands and stepped into the mysterious Tongtian sword building.

"What was the previous virtual shadow and the sound?"

Su Bai's eyes suddenly darkened, and a desolate atmosphere of vicissitudes came to his face. Su Bai looked up at the first floor of the Tongtian sword building, and his eyes showed a little shock.

The space here seems so vast that you can't see the edge. The only thing worth noting is that there are several black stone tablets standing and crawling in the center. These black stone tablets give people a cold and incomparable feeling like ancient fierce animals, and the whole body is haunted with black gas like ink.

"Is it the inheritance of the sword stele, like the existence of the sword stele building?"

Su Bai saw these sword tablets and his heart beat faster. He was always calm. He rarely had such violent emotional fluctuations. He walked carefully to the black stone tablets.

However, the moment he really saw these stone tablets, the excitement in Su Bai's eyes immediately disappeared, "what's the matter? How can there be so many cracks on these stone tablets?"

On the dark stone tablets, there were cracks like spider webs, and the ink like black fog rolled out from these cracks. Su Bai could see a fist seal on these stone tablets, as if it was this fist seal that almost broke these stone tablets.

On one side of the stone tablet, there is a futon hovering in the air, which has nothing to do with the gloom.

"You can go up to the second floor of the sky by stepping on the sword PU."

The hoarse voice sounded again in the dead area. It seemed to ring out behind Su Bei, but Su Bai turned and looked empty.

His eyebrows wrinkled slightly. Su Bai looked back on the black stone tablet and stepped on the futon. A dizzy feeling of changing stars swept over immediately. When this feeling disappeared, Su Bai immediately looked up and saw that he was in a vast space.

Here, there are also several black stone tablets standing in the center, but these stone tablets are broken, as if they were cut off with a knife.

Su defeated and put his hand in front of the black stone tablets. Apart from the cold touch, these stone tablets are no different from ordinary boulders.

"Stepping on the sword can go up to the third floor of the sky."

The hoarse voice sounded again, as if it came from the Jiuyou abyss, cold and piercing.

After a little hesitation, Su Bai boarded the futon again.

In the third floor of Tongtian, there are still stone tablets standing, but these stone tablets are divided into a pile of rubble, as if they were smashed by one palm.

Su Bai continued to move forward. Black stone tablets were also needed on the fourth floor of Tongtian. Eye-catching holes appeared on the stone tablets, as if they had been pierced by a long gun.

Seeing this scene one after another, Su Bai had a vague idea that these stone tablets had been forcibly destroyed.

Looking at the fourth futon, Su Bai stepped on it again. Just at the moment of stepping on it, a terrible repulsion suddenly surged out of the futon and forced Su Bai's body out.

"Those in the congenital environment have no talent to ascend the fifth floor of the sky." the hoarse voice rang out slowly and echoed.

Su Bai frowned slightly, glanced fiercely across the empty world and said softly, "what are you?"

In the dead silence, only the voice of Su Bai echoed in the whole world.

"Is it the only one who is strong in the past, but even if he is so strong, he has become a piece of loess..."

Su Bai's eyes changed indefinitely, and his eyes turned to the futon nearby. According to this voice, whether he could climb the several floors of Tongtian sword building depends on his cultivation. As long as his cultivation is not in line with this futon, it will not work, and even appear terrible repulsion.

"In other words, this Futon can distinguish my cultivation realm. It's really evil." Su Bai murmured, but a crazy idea appeared in his eyes. The mustard bracelet on his wrist flashed brilliance in vain. In a flash, a pale skeleton appeared beside Su Bai.

Su Bai hurriedly supported the skeleton with both hands, and his body was slightly heavy. Then he took the skeleton and set foot on the futon. At this time, the repulsion force on the futon immediately disappeared.

"The triple only my sword formula, and the emperor's road territory is seven, which can go up to the ninth floor of the sky."

The hoarse voice sounded again, and Su Bai's figure had appeared on the fifth floor of Tongtian.

"The emperor's way is seven. Is this the cultivation of publicizing ya? But this Futon is really terrible. You can know his cultivation only by publicizing Ya's bones."

"The ninth floor of the sky..." Su Baimu was excited, holding the bones of xuanya, and went straight to the futon.

There are still black stone tablets on the sixth floor of Tongtian, but there are cracks on these black stone tablets

Tongtian seventh floor... Tongtian eighth floor

The same scene continued to appear. After su Bai stepped on the ninth floor of Tongtian, his eyes changed
