"Roar! Roar..."

At the moment when Lin Feng had just offered his sacrifice to practice Xuantian, he turned his head after solving the black pupil lightning swallowing dragon of the sword spirit. A pair of gloomy and cold big pupils stared at Lin Feng fiercely.

However, this time, the black pupil lightning swallow Yunlong did not open a pair of vertical pupils in the center of the giant pupil again, but poured out a big mouth and suddenly opened.

Although the vertical pupil in the center of a pair of giant pupils can release the most powerful black lightning, it also consumes a lot of body. It has consumed a lot of physical strength just once.

Most importantly, once the consumption of the vertical pupil for the body reaches a certain height, it will fall into sleep. Without thousands or even thousands of years of cultivation, it can't be restored at all.

Moreover, Lin Feng in front of him is still at the juncture of refining medicine. He has no time to care about it. He can easily solve it without using vertical pupil.

"Boom!"

Black pupil lightning swallows Yunlong, which has a huge mouth of nearly 1000 square meters, and directly ejects a black light with a diameter of 20 or 30 meters.

Such a black light, the moment it erupted, was like a pillar of heaven and earth. Then, like the flood after the breakup of rivers and lakes, it swept towards the forest peak. Its potential is powerful enough to shake the world and unstoppable.

Not to mention a glance, you can feel the terrible smell of burning and corrosion only from the black lightning Tianzhu, which is filled with the open breath between heaven and earth.

As if this black lightning Tianzhu had the power of burning and corrosion, enough to burn the sky and earth. Just the moment of sweeping, it will submerge the forest peak.

Along the way, the black lightning Tianzhu shows the power of burning and corrosion incisively and vividly. Wherever you go, the air is directly burned and corroded to a clean place, forming an absolute vacuum.

"Bad!"

Lin Feng secretly shouted that he was terrible, and his face was dignified as never before.

From the black pupil lightning cloud swallowing beast, he knew exactly how terrible the black lightning power from his huge mouth was.

Just a few strands are enough to burn and corrode the body to a severe injury, not to mention this black sky awn with a diameter of 20 or 30 meters. If you are drowned by it, you must die in an instant.

"Xuantian armor skill!"

"Five element shield!"

At this time, Lin Feng is at the critical moment of absorbing medicine. Once interrupted, all his previous efforts will fall short of success.

In a hurry, he could only drink loudly and hurriedly offer the strongest defense immortal method with the blessing of Xuantian armor. As the five elements immortal body, it has the strongest defense immortal method. The original power of the five elements shield is extremely terrible. Now, with the blessing of Xuantian armor, its defense power can be multiplied.

Of course, it is absolutely impossible to completely resist the attack of black pupil lightning swallowing dragon. But at least, we can get Lin Feng some time.

As for the final result, it depends on whether he can successfully refine all the remaining medicinal power and complete the breakthrough in the realm of cultivation with the blessing of red practice of Xuantian during this period.

"Hua la..."

With the blessing of Xuantian armor, after offering the five element shield, the strongest defense immortal method, the five element power of the flesh body and the five element aura that can be mobilized between heaven and earth are like running water, winding and gathering on the body surface of Lin Feng with the sound of "clattering".

In the twinkling of an eye, a colorful eggshell light curtain has been formed.

"Bang!"

"Bang bang!"

"Bang Bang..."

Almost at the moment when the colorful light curtain eggshell was just formed, the black lightning Tianzhu with a diameter of 20 or 30 meters has swept through with an unmatched surge.

It's like a giant spirit God waving a huge hammer in his hand and smashing a Hong LV clock. It makes a loud noise and explodes. The multicolored light curtain shield armor is nothing different except a burst of shaking.

After about a dozen breaths of stalemate, accompanied by the colorful light curtain shield, a more violent shaking, a full 20-30 meter thick black lightning Tianzhu, finally burst out of strength. Once again, it turned into a little black awn, which drifted in the wind and filled the air.

The black tianmang Tianzhu has a great impact of the explosion, which makes the multicolored light shield, which is already fluctuating violently, swing more and more crazily. It's like a boat adrift on the ocean overnight, suddenly encountering a violent storm.

Although the colorful light shield and armor bumped violently, it was still intact in the end. However, under the erosion of bits and pieces of black light, many traces of burning and corrosion also appeared on it. In many places, the naked eye can clearly see the black spots left after being burned and corroded.

"We must persist until the moment when the magic sea strange Xuan grass and red Lingtong fire fruit are completely refined!"

Lin Feng did not dare to be distracted. In a whisper, he still tried his best to refine the remaining medicine at the fastest speed with the blessing of the taboo secret art of red practice Xuantian.

Until now, the success or failure depends on whether he can successfully refine the remaining medicine and complete the breakthrough before the burst of the colorful light curtain shield.

"What... Your immortal magic shield has such terrible defense?"

"Damn it!"

Black pupil lightning devours Yunlong and is furious.

It is the only one. With its own blow, it can easily solve Lin Feng.

But I didn't expect that Lin Feng at this moment offered up the immortal Dharma shield with such terrorist defense. Even its black lightning Tianzhu with a diameter of 20 or 30 meters could not break it.

Most importantly, apart from the black spots of corrosion and burning, there was no real destructive damage.

"Roar, roar..."

The angry black pupil lightning swallowed the cloud dragon, and the roar of rage continued.

Every time you delay one minute, the medicine power of magic sea strange XuanCao and red Lingtong fire fruit will be more and can't be forced out. The black pupil lightning swallowing Yunlong, who dared not delay any more, did not hesitate to show great weakness in his body. He opened it again. In the center of a pair of giant pupils, it was only a black vertical pupil.

"Boom!"

Almost at the moment when the black vertical pupil opened, the black pupil lightning swallowing dragon burst out with that powerful black vertical pupil, one after another.

Each flash of lightning is like a real flash of lightning. Although its thickness is far from that of the huge mouth, its power is unprecedented. Just one, it is more powerful than the power of the black lightning of 20 or 30 meters thick ejected from the huge mouth.

Under the impact of continuous lightning and black lightning, the fluctuation becomes more and more violent on the colorful light curtain shield. As for the corroded places above, they are also increasing.

From black spots to black silk threads, to shocking black lines. If this situation continues, I'm afraid that in a short time, the five element light shield will be completely burned and corroded.

"Click!"

After a while, the five elements light curtain shield was burned and corroded, a real crack.

"枼 枼 枼!"

"Humble human cultivator, die!"

Looking at the crack that exploded, the black pupil lightning swallow Yunlong finally gave up. With the attack of black lightning from the vertical pupil, he swayed instead. The huge dragon tail with a length of hundreds of meters.

After several times of gaining momentum, he tried his best to swing the dragon tail and mercilessly hit the crack on the colorful light shield.

"Boom!"

The body of the huge fierce beast of the black pupil lightning swallowing cloud dragon is a full kilometer, which is the tail of the dragon, and it is also a full hundreds of meters long.

The hardness of such a huge tail is comparable to that of an ordinary first-order inferior artifact. The power that can burst out under the sweep of violent power is extremely terrible.

If you are swept by it, let alone ordinary rivers and lakes, it is a heaven and earth, which will disappear in an instant.

"Boom!"

With the hundreds of meters long giant tail sweeping over, one side of the world was directly swept away with a huge crack like a gully.

Not only that, even the colorful light curtain eggshell, which had already exploded a crack, showed cracks in an instant. Although most of these cracks are very small, they are also very terrible when they gather together.

In this case, if the black pupil lightning swallows the giant tail of the cloud dragon, it can definitely explode the colorful light shield in an instant.

"It can only be a desperate struggle!"

"Drink!"

When his eyes turned, Lin Feng drank violently and absorbed all the residual medicine in his body and all the brain into his mind.

After all the remaining medicinal power is absorbed, the shenzang is instantly filled in Lin Feng's body. If someone can go deep into Lin Feng's body, he can find that the crazy expansion of shenzang is like a balloon filled with air, which has almost reached the edge of bursting.

Even several times, some tiny cracks appeared faintly. However, in the end, it was safe and safe. The crack dissipated and expanded to shenzang, which could burst at any time, slowly returned to normal.

"Hoo... It's dangerous!"

Feeling the change of the spirit in his body, Lin Feng took a breath of cold air with lingering palpitations.

At this time, the black pupil lightning swallowed the cloud dragon, and the huge tail hundreds of meters long finally swept to it.

"Click, click... Boom!"

Just the moment the giant tail swept down on the cracks of the five elements of light shield, the whole light shield exploded in an instant, and then burst.

Turn into colorful lights and disappear.

"Boom!"

Black pupil lightning swallows Yunlong, hundreds of meters of huge tail, sweeps and explodes colorful light shield armor, and then continues to sweep down towards Lin Feng with the potential of thunder.

"Die!"

"枼 枼 枼!"

At this moment, the black pupil lightning swallowed the cloud dragon, and finally revealed it again, and the proud Lintian laughed.

It only thought that with this blow to its huge tail, it would sweep the forest peak and destroy its flesh, spirit and soul. But unexpectedly, at this time, Lin Feng suddenly burst out a powerful force of crazy soaring.

In the face of this terrible force, Rao felt a fear of facing death with its strength.
