The two of them were delayed at the entrance of the passage for two days, when suddenly there was some light ahead.

Ling Li walked over vigilantly, only to see the entrance of a huge deep circular ground cave with a diameter of about thirty meters appearing in front of him.

The light emanated from the vertical walls of the cave.

The stone walls of the cave were smooth, with some ancient patterns etched into them, glowing dimly.

The cave is so deep that there is no end in sight, and it seems to go straight underground.

"There seems to be an underground space below, supported by formation prohibitions, and there seem to be some prohibitions arranged on the walls of this cave." Ling Li exuded his divine sense, sensed it slightly, and said.

Sophia nodded, and took out a disk-shaped spirit weapon with a diameter of about three meters from the Pastoral Ring.

Ling Li looked at it, and saw that the spirit weapon was divided into eight pieces, each with extremely complex formation patterns on the surface.

Sophia pointed to the four chambers in the middle of the artifact and said, "This is a field-effect vehicle capable of carrying four crew members. It was obtained in the secret realm of the Arika Golden Tower, and there are many practical magic circles depicted on it, and the defense is very strong. ”

This is basically the same answer given by the system.

This thing is considered a medium-sized immortal weapon, and this level of immortal weapon is already very high-level in the Chiyan Continent, and it seems that Sophia's status in the Morton Temple is not low.

Sophia opened the cockpit of the flying immortal machine, "Let's go down in this flying machine." ”

Ling Li hesitated slightly, but still boarded the aircraft and sat in the flight cabin.

He originally wanted to go down directly, thinking that when the space below the ice gap in the Mustang Ice Field penetrated the protective barrier, his armor was broken and almost stripped naked, and he still thought it was more appropriate.

At least don't worry about Chiguo's physical distress.

Sophia sat down in the cockpit on Ling Li's side and started the aircraft.

This immortal-level spirit weapon began to slowly descend along the entrance of the cave, and when it encountered some protective formations on the cave wall, the energy surged, and it collided violently with the protective energy on the surface of this flying spirit weapon, bursting out with clusters of bright light, giving people the feeling of walking through a tunnel of time and space.

The craft gradually accelerated, and after only a few minutes, Ling Li estimated that it had descended about three thousand meters, and began to penetrate the protective barrier of underground space.

"Bang!"

A large cloud of sparks bloomed on the surface of the aircraft, and Ling Li felt a flower in front of him, feeling that he had entered another space.

The craft then slowed down, preparing to land slowly at the bottom of the crater.

There is a space at the bottom of this cave, it looks like a huge square, but it is facing an area near the patio of this cave, which is full of white bones, like a small mountain.

The aircraft had just touched the ground in this square, but it was very strange that it was teleported into another dimension.

The scene in front of them suddenly changed, and Ling Li found that they had entered a huge stone hall with a vast area and a dome as high as a hundred zhang. The area of this stone hall is more than ten kilometers square, which is a hundred times wider than the space at the bottom of the cave just now.

Around the stone cave, there are countless light crystals and pearls, emitting a soft light, making the entire interior of the hall shine, magnificent and magnificent!

"It's ......"

Ling Li was shocked to find that the place where the aircraft landed was actually surrounded by a huge pool of blood hundreds of zhang square!

In this pool of blood, there were countless bones, most of which were all kinds of animal bones, and there were even many human bones. Under this mountain of bones, there was still some semi-dried blood at the bottom of the pool. I don't know how many years this blood pool has existed, and the entire hall is filled with a faint layer of dark red blood, and the air seems to be filled with a rich bloody gas.

The place where the aircraft landed, is a nine-sided bluestone altar that is 100 zhang square, emitting bursts of blue and red light, in the center of this altar, there are ten black stone pillars more than one meter thick and more than ten meters high, it seems that the entire altar together constitutes some kind of ancient formation.

Seeing this scene, Ling Li's eyes contracted, and Sophia in the cabin on the other side was also pale with horror and her body stiffened.

The two of them sat motionless in the flying machine, and after about a few dozen breaths, they saw that there was no movement on the altar, and their hearts calmed down slightly.

Sophia opened the hatch of the cockpit and prepared to go up to the altar, but at the moment she made a slight movement, suddenly, there were slight ripples on the crimson surface of the almost dry pool of blood.

At the moment when the ripples were generated, Sophia's body suddenly stopped.

Her face was pale, her body trembled, and a strong sense of fear and crisis emerged, as if some kind of terrifying creature existed under the pool of blood, staring at her coldly.

"Don't move, don't panic, I'll see what the situation is." Ling Li was also aware of the changes in the pool, and suddenly opened his mouth at this moment and said in a low voice.

Sophia bit her lower lip, struggled inwardly, and still closed the canopy again according to Ling Li's words.

Ling Li sat in the cockpit, continuing to observe the bloody dead space and the blue-red altar through the assistance of the system.

This altar is glowing with a strange blue and red light, and on the altar, the formation composed of one in the center and nine black jade pillars on the periphery is irregular in appearance, and it looks quite strange. The nine jade pillars on the periphery, and between them and the blood pool, there seems to be something similar to the roots of plants, which connect them together to form a whole.

Ling Li's gaze swept around, and finally froze at the top of the largest black jade pillar in the center of the altar, at the center of the formation, where he felt a subtle fluctuation of energy.

"This is the breath of rules, is this thing the 'seal of the world' of this space?"

Ling Li squinted his eyes, he had seen such a blood pool once, it was under the underground cave of the Holy Heaven Sect in Wild Horse Mountain, and now it was stored in the treasury of the trial space, which could be regarded as a low-grade demon immortal weapon.

According to Tantai Makino, it should be something from the Blood Demon Sect of the Middle Heaven Realm.

And compared with this blood pool, that low-grade immortal magic weapon is a small thing, and it is obvious that this blood pool has a much higher level.

"That Holy Heaven Sect's blood pool is used to cultivate blood demon skills, and this blood pool, in terms of formation principle, is obviously different from that cult blood pool......" Ling Li's gaze looked at the black jade pillar in the center of the formation, and his face changed. The black jade pillar was connected to the blood pool, through a red blood line at the bottom of the altar.

The end of the blood line is where the blood ripples at the bottom of the pool just now.

In that spot, in the pool of blood sat the blood-colored skeleton of a human dragon head......
