The entire auditorium was shaking, the colors in the five rings on the ground were rapidly fading, and the spiritual words on the stone tablet were gradually losing their luster, and the spiritual power inside was rapidly disappearing at a speed that was already visible.

A crack suddenly appeared on the stone tablet of "Ka Ka Ka ......", and soon a second and third ...... appeared Almost in the blink of an eye, the surface of the stele was covered with dense cracks.

And inside the stone tablet, a strong bloody aura also burst out, and at the same time, there were powerful energy fluctuations. It was hard to imagine what kind of existence the monsters that were sealed inside, and with this momentum alone, even ten monsters like Lance could not reach it at all.

Aurora also felt the aura of the monster in the stele, and the surprise in her heart was not trivial. Because she was familiar with this kind of monster aura with a strong bloody aura, it was the unique aura of the powerful monsters in the Demon Realm. It can be felt that the level of this hydra is not even much worse than that of the White Bone Corpse Demon.

Flashed to Jason's side, flew with his legs together and kicked him down, and the whole person rushed to Gao Jin's position with his strength.

At this time, Gao Jin's state was extremely bad, and the spiritual power in his body was depleted again, and he couldn't rely on taking spiritual power to recover quickly in pillmaking. At least three ribs were broken, and it seemed to hurt the internal organs, and even a slight movement of the body would cause a sharp pain.

His forehead was covered with beads of sweat the size of soybeans, and he gritted his teeth and endured the severe pain, trying to raise his hand to take out the healing potion from the storage space. But the arm was not able to lift it at all, and there was no spiritual power at all, so it was difficult to cut through the storage space.

"Am I going to die? The strength is still not strong enough......" Gao Jin's mind is like ashes.

He was still conscious, and he could feel the momentum of the hydra erupting from the stone tablet. Don't say that he is now seriously injured and unable to fight again, even if he is in good condition, when he encounters a monster of this level, he can only turn around and run away.

There was a weak bitter smile in his heart, this time he was extremely unlucky. What was originally thought to be a simple task has actually evolved into the current situation, which is really not a simple bad luck, but a top-notch one.

Aurora on the other side was even more anxious, and the danger of this scene was also greatly unexpected by her. The problem now is whether or not you can destroy the monster and prevent the Five Elements Seal from opening. It's about how to get yourself and your companions out of this place safely.

In this city, which is more than 1,000 meters underground, it is impossible to get in touch with the outside world. Otherwise, such a strong demonic aura would definitely attract immortals in the spirit world. However, now that he is deep underground, he can't get the immortals to come and help, so he can only rely on himself!

Aurora didn't want to see her companions lose their lives in front of her eyes, having watched her two friends die in front of her not long ago. Although the dead spirit detective has a chance to be resurrected, he will lose all the memories of becoming a detective.

When she found her two resurrected companions the other day, they had no memory of who they were, as if they had never met strangers. It broke her heart, and she didn't want to bear it again!

"No matter what, you can't leave your partner behind!" Aurora gritted her teeth and quickly moved towards Gaojin.

At this time, the colors in the five auras completely disappeared, and the spiritual characters on the surface of the stone tablet gradually faded. Lance, who was originally in the red aura, suddenly trembled in his body, and a black mist flew out of him.

The black mist quickly condensed into an entity in the air, and it was a flying snake. Its appearance was more than ten times larger than those ordinary black flying snakes, a single triangular head was like the size of a human head, the two pairs of wings behind it were very large, and a pair of snake eyes had a sinister and vicious light.

At the moment when the monster left the body, Lance's blood-red eyes returned to normal. But he was stunned for less than half a second, and immediately let out a heart-rending scream. A large amount of blood burst out from all the wounds on his body almost at the same time, and the blood in his whole body was like a flood that burst the embankment, and the whole person almost turned into a fountain of blood!

Terrible screams echoed through the Great Hall, but Lance only let out two roars before dying of rage.

The giant flying snake monster flapped its wings in the air, and its body twisted and rushed downward, and when it got close to Mike, it instantly turned into a black mist and submerged into Mike's body.

Seeing this scene, Aurora didn't even have time to curse, she was already impulsively moving to her side. In an instant, he took out the disc flying machine from the storage space and threw it above his head, and almost at the same time he possessed Gao Jin and grabbed him, and then jumped with him onto the disc flying machine that was gradually recovering its original shape.

Everything was done perfectly, and when Aurora landed with Gao Jin, her feet were just on the surface of the disc aircraft.

I secretly said in my heart that I was lucky, and I didn't have time to open the cockpit. Immediately drive the aircraft towards the east side of the auditorium, as long as you crash through the glass window on the wall and fly outside, you will have a chance to survive.

"Just get away and open the portal as soon as possible. When you get to the surface, no matter how powerful the monster is, you won't be afraid! Aurora secretly rejoiced.

But before the disc flew in front of the window, a violent shock wave mixed with countless black fragments blasted away from the center of the auditorium in all directions. In an instant, he overturned the flying machine and crashed into the wall of the auditorium with the two people on it.

The walls of the Boom ...... Auditorium were not pierced by the aircraft, but only a hole was punched, which stuck the aircraft in the wall.

The two people on the frisbee fell directly from above, and Aurora hurriedly grabbed Gao Jin, so that he would not be seriously injured, and this fall would directly cost his life. In a flash, Aurora returned to the frisbee with Gao Jin. Fortunately, the frisbee itself has the ability to fly, and although it is stuck on the wall, it can still bear the weight of two people.

There was no time to panic, and when Aurora saw Gao Jin's dying appearance, she knew that she had to heal him immediately. She hurriedly took out the healing potion, opened Gao Jin's mouth and poured it in, and then stuffed an ordinary recovery pill into his mouth.

This ordinary recovery pill is not very powerful, and its effect is relatively slow, but because of this, it can be taken multiple pills in a row. Now that he can no longer take the Spiritual Power Recreation Pill, he can only use this ordinary medicine!

Aurora herself takes a pill, and she must also bring herself back to full state. However, it's not to destroy monsters, but to wait for a little more certainty when you run for your life.

It turned out that the terrifying shock wave before was the momentum that the hydra burst out of when it broke through the sealing stone tablet. Under the shock wave that roared out, all the people around the stone monument were blown upside down and flew away, rolling out no less than twenty or thirty meters.

Even Mike, who was possessed by the strange snake, couldn't withstand the powerful impact, and took six steps backwards to barely stand still.

"Whew...... Yes...... Lao Tzu is free! Whoahahaha......" An unbridled laugh echoed throughout the Great Hall and even throughout the underground city.

I saw that where the original stone tablet was located, a burly man wearing blue and black scale armor appeared. There seemed to be many strange patterns on his large, smooth and mirror-like head, which looked quite like a snake pattern. At first glance, he looks like an ancient mighty warrior, but his whole body exudes a domineering aura of evil and destruction!

This bald man is the human form transformed by the hydra, and it is a great shame for him to be sealed in this place for more than ten years.

"Huh? It's you! Hydra seemed to sense something and suddenly looked up, and its dark red eyes seemed to penetrate the top of the Great Hall and see something in the air.

"Whoosh!" "Boom!"

I heard a sound of breaking through the air, and then I saw a large hole in the top of the auditorium. The reinforced concrete of the roof is like tofu dregs, which can not withstand the impact of a hydra.

The hydra was hovering in the air a hundred meters above the ground, glaring at somewhere in front of it and slamming out with a punch. The fist wind turned out to be black, and it seemed to contain fierce snake venom in it! But the extremely sharp fist wind didn't hit anything, and flew straight out for hundreds of meters before it dissipated.

"Nine-tailed snake, I didn't expect you, a half-dead guy, to still find me." The place where the voice came out immediately appeared a withered yellow and thin human form, almost like a leather skeleton, and it was actually a white bone corpse demon!

It turned out that after the white bone corpse demon was seriously injured, he followed the advice of the newly recruited little brother Centipede, and absorbed the energy of mortal monsters everywhere to repair his own injuries.

The hundred-legged centipede, who had been asking for news about the monster a few days ago, received the news that Hydra's subordinate Winged Flying Snake was preparing to come to break the seal and rescue Hydra.

As early as many years ago, the white bone corpse demon, who was also a demon king-level existence in the demon world, had a grudge against the hydra, and the two sides fought without knowing it. The last time, the White Bone Corpse Demon designed to overshadow the Hydra, which greatly reduced the poisonous strength in its body. Originally, he was going to take the opportunity to destroy the Hydra and swallow its power, but it escaped.

For more than ten years, there has been no news of the Hydra in the Demon Realm, and the White Bone Corpse Demon still thinks that it is dead. Unexpectedly, he was exiled to the mortal world and sealed in this underground city by spiritual detectives.

After learning the news, the White Bone Demon led Yuri and the Hundred-legged Centipede to secretly follow the Winged Flying Snake. has been quietly moving on the side, releasing a long line ready to catch a big snake.

The previous earthquake shook and cracks in the earth closed, which were some of the methods adopted by the White Bone Corpse Demon in order to act without being detected by the spirit world. It was precisely because of their actions that the light network in the passage where Gao Jin and the others were located was triggered, and almost caused the group to die in vain.

"You dead skeleton, Nima came just in time, Lao Tzu will dismantle your bones today!" The hydra turned around and faced the Bone Corpse Demon.

"That's what I mean! You two, go deal with the next two. The Bone Demon commanded with his hands crossed over his chest.

"Yes! Lord Demon! "On the left and right sides of the White Bone Corpse Demon, a figure appeared almost at the same time. It was Yuri, a black dwarf with a blank face, and a centipede that had turned into the appearance of a young man.
