Within the forbidden curtain, Xue Zhen's cultivation and his mana sea were constantly expanding, until that day came, his mana sea impact broke through to the third order, and the edge of the collapsed mana sea, and a huge amount of immortal aura flowed in, driving a huge whirlpool, and Xue Zhen's mana continued to surge.

There is such a behemoth, in the depths of this blood domain, a place that no one can know, a place that not even the loach spirit creature or even the Blood Emperor has ever visited.

Within this place, it was attracted by this huge Xuan Stream, which had driven the long-lost turmoil of the Blood Domain, and was alarmed, and it also swam towards the core of this Blood Swirl.

This thing has a body of nearly 1,000 zhang, and the part of it, like the body of a turtle, is flat and stable, and four sharp claws stretch out from both ends, and the movement is slow.

At the back of its body, a blood-black tail with three feathers writhed, and the nearby blood water actually formed a light swirl in it, which was extremely strange.

His head is a huge blood-black pillar with a length of nearly five hundred zhang and a diameter of forty or fifty zhang, which should be its neck, and the head in the front section is round and blunt, and its appearance is relatively kind, but its eyes actually have a fierce aura, which can make people tremble.

It was such a huge spiritual creature, lightly crossed the "defense line" of the loach spiritual creature, and lightly burst into the blood curtain, and soon, this seemingly huge spiritual creature had fallen outside the forbidden curtain where Xue Zhen was, feeling the blowing brought by the blood xuan, staring at the forbidden curtain, thoughtful.

As for Xue Zhen inside, he was still filling his mana, because he had reached the third order, the sea of mana was only about six or seven percent now, and the blood meridian of the Stygian Sea was still stimulating, and a huge amount of immortal breath was being filled.

Suddenly. With a "bang", all the tactile senses that Xue Zhen put away, the sound that could be heard before it was triggered to Xuan Tiancong's ears, Xue Zhen suddenly opened his eyes, looked out, turned around, and had sensed such a behemoth.

"Bang!"

The loud noise came out again, not loud and deep. But this area within the blood domain can hear the deep sound coming from the silence, even the loach spirit creature in the distance.

But the inside and outside of the forbidden curtain have a total of three layers of defense, not so easy to break, Xue Zhen carefully looked at this blood-black monster with his thoughts, its outstretched spiritual pressure has reached the Immortal Monarch stage, his brows were slightly suppressed, and then he had a simple thought:

"Turtle?"

"No, the Xuan Tortoise would never appear in such a blood domain, but maybe it was a mutated thing, could it be the spirit pet raised by the Blood Emperor?"

Xue Zhen was between slow thoughts. The blood-black monster outside, a monster similar to the Xuan Turtle, could sense that the nearby Blood Swirl was slowly dissolving.

However, this has always been a loner. The turtle monster, which comes and goes freely, has encountered this obstacle, and it has a resilience, and it seems to be on this forbidden curtain.

"Bang!bang!bang......"

Successive impacts. There was also a rather slight "buzzing" sound in the outermost forbidden curtain, and Xue Zhen could barely hear and feel the crashing sound, only to see him immediately throw his sleeves out. The forbidden light burst out, and the white bone trap beast array with 100 steel cesium had been added to the outermost layer, resisting the attack of the turtle monster.

For some reason, this turtle monster still couldn't erase this light curtain when he saw it, it was originally just a bombardment of the head, and on the soles of its feet, there were actually a few sharp claws, and the whole body was lying on the forbidden curtain, a little clumsy head banging with claws, and the crashing sound of "buzzing" started again.

Seeing this situation, Xue Zhen was already able to basically determine that this turtle monster should not have opened its spiritual intelligence yet, and it should be an unconscious move now, Xue Zhen smiled lightly at the corner of his mouth, and rushed away with a sharp point.

"Bang" a heavy punch, it actually hit the belly of this turtle monster, on the extremely hard shell, Xue Zhen bore the brunt, and was shocked back by its strong resistance, and the blood in the forbidden curtain flowed rapidly.

However, quite unexpectedly, the Xuan Turtle monster was only shocked out of less than three feet, and instantly lay on the forbidden curtain again, making Xue Zhen feel a little speechless.

Moreover, this turtle monster seemed to realize that this was an interesting place, and the movements of the four claws were more frequent, and the head and neck were actually hitting at a faster frequency, and it looked like it wanted to break through.

The heaviest attack of this turtle monster is its skull part, Xue Zhen uses the white bone trap beast formation as a defense, and it can basically be completely resolved, its four claws are not good at heavy attacks, and the scratching part makes this forbidden formation, which is not too powerful, just in a critical state, on the verge of collapse.

Xue Zhen secretly calculated, he knew that the Xuan Turtle's defense was quite amazing, however, its head did not have that terrifying chitinous resistance, and it should not be a problem to repel it.

Thinking of this, Xue Zhen clicked under his feet again, and rushed straight away, and suddenly landed on the edge of the forbidden curtain, which was quite close to the head of the Xuan Turtle Monster, but at this time, an unexpected scene happened.

The head that had been bombarding the forbidden curtain unexpectedly stopped, the snake-like neck was bent back, and in the black blood-colored darkness on the skull, the pair of black eyes stared, staring at the forbidden curtain, staring at the forbidden curtain that could not be seen at all, Xue Zhen's position, as if he could see Xue Zhen, was quite strange.

What is going on? Xue Zhen's mind flashed this thought, he looked at this turtle monster, and watched its body slowly break free from the forbidden curtain, Xue Zhen's puzzled gaze, but the sea of thoughts was constantly flying.

Xue Zhen knew that these three layers of forbidden curtains were all magic circles that he was familiar with, and judging from the formation technique, it was impossible for people outside to perceive the situation inside, but this turtle monster seemed to be able to know Xue Zhen's arrival, and could know Xue Zhen's threat, so he avoided it in advance.

At this moment, Xue Zhen and the turtle monster looked at each other, Xue Zhen could see this turtle monster, and he could see that in its eyes, it seemed that his own small figure appeared, Xue Zhen didn't know why, he searched his own sea of thoughts, including the various bizarre characteristics of the turtle that he knew before, and he couldn't find any roots.

And Xue Zhen also tried to dodge sideways, flashing left, protruding right, running up, and pressing down, this turtle monster could move his eyes discerningly, and the movement was not large, and Xue Zhen could barely distinguish it.

Perceiving this scene, Xue Zhen had a clue, he raised his hand to support his chin, stroked, pondered, considered, frowned, and formed a silent confrontation with this turtle monster. (To be continued......)
