A streamer flew through the sky, and there was a sudden strange movement in the desert area dozens of meters ahead, and hundreds of sandmen flew into the air to intercept the streamer.

"Climb to the top!"

Duguren slashed out the fourth form, and the sand in the desert condensed into a mountain that broke through the sky and rose from the ground.

"Four-tails!"

Dugu Ren shouted, the four-tailed magic crystal beast that had been accumulating strength for a long time manifested, and the spiritual power of Duguren's whole body was wrapped by the power of the four tails, and the cultivation of the two levels of the Immortal Tribulation was directly improved to the sixth level of the Immortal Tribulation.

The thunder of the sky, the fire of the earth, the extreme cold, and Jin Ge, are entangled around Duguren.

The power of four different attributes was condensed into the power of a single sword, and within a range of one thousand meters with Duguren as the center, a huge cross knife of four different colors appeared.

The cross knife grinded like a meat grinder, and hundreds of sandmen at the peak of the Immortal Tribulation Realm were ruthlessly strangled.

In Dugu Ren's body, the nine-tailed magic crystal will nourish the four tails and Dugu Ren with the source of power all the time, just now, the nine-tailed magic crystal suddenly trembled, and the original trickling fairy power suddenly rushed into the Dugu Ren realm sea like a flood that burst the embankment, in its meridians, limbs, and hundreds of remains, violently washing.

A crisp sound of "click" sounded from Duguren's body, and Duguren and Siwei's complexions changed.

"Boom!"

"It's not good, it's not a good sign to be in the Cave of Death. ”

The voice of the four tails came out, it was very worried, once it became a war beast, the immortal tribulation would have to be crossed together, and it could not be avoided, and its difficulty naturally rose in a straight line.

A shackle appeared on the surface of Duguren's body, and before he could get ready, the shackles were completely broken, and the triple immortal tribulation fell in response.

The light of the Immortal Tribulation, which was richer than the previous two times, turned into a figure in the process of falling, and when you looked closely, it turned out to be exactly the same as Duguren.

The humanoid Immortal Tribulation also held a giant knife and cast a four-color cross knife, which was the same knife technique that Duguren had just cast.

The four tails are angry, it is not happy, this thing dares to steal its own original?

That's right, the idea of condensing the power of several different attributes of the four tails into a cross knife was proposed by the four tails, according to the idea of the four tails, if Dugu Ren can fuse the nine-style knife technique of "With the Monarch" with the power of the four tails who will evolve the nine tails in the future to form a rice-shaped knife, that kind of power can only be described as destruction.

After all, Duguren's sword path is unique, and the bloodline potential of the four tails can evolve to that level in the future, and it can indeed destroy the world.

Duguren's cross knife collided with another cross knife, and the two forces canceled each other out, causing the impact to wipe out the surrounding desert.

Dugu Ren held the black iron giant knife, and the blue water martial soul merged into the core of the knife along the knife channel of the black iron giant knife, and Dugu Ren's strength soared to the peak of the ninefold immortal tribulation, and at this time, the nine-tailed demon crystal in the body rotated wildly, merging all the remaining power into Dugu Ren's body.

"Click"

A transparent shackle broke, and Duguren felt that his body and soul had been sublimated in some way, just like the body carrying a 10,000-pound boulder suddenly sent, and the feeling of comfort rushed from head to toe.

However, Duguren and the four tails' expressions became more serious, the third immortal tribulation had not yet passed, the fourth shackles were untied, and the fourth immortal tribulation came uninvited.

"The Cave of the Past Life is really evil, according to reason, no matter how strong the strength is, before breaking through the Immortal Tribulation, the next Immortal Tribulation will not come. ”

The four tails are the body of a demonic beast, more sensitive and precise than human intuition, and it is almost certain that the problem lies in the Cave of the Afterlife.

"Type 1: Open the way!"

"Second Form: Centering!"

"Third Style: Ten Thousand Heavy Mountains!"

"Fourth Style: Ascend to the Peak!"

"Fifth Style: Initiation!"

"Sixth Form: Destruction!"

"Seventh Form: Tenderness!"

"Eighth Style: Broken Intestines!

"Ninth Style: Absolute with the King!"

Duguren's white hair was flying, holding a turquoise giant knife, and with the blessing of the four tails, he rushed towards the humanoid immortal tribulation.
