The heavy iron door opened automatically, and an unexpected refreshing breath suddenly hit their faces, they were all almost used to the sweltering heat in the Extreme Cold Prison, but they didn't expect that there was such a refreshing cool air underground, it didn't look like an underground cave where mysterious giant beasts were imprisoned.

The area ahead was unexpectedly large, and even the team members with night vision devices could not see the end of the darkness, but they could vaguely see a large waterhole in front of them, and the water was now sending out ripples of silver light, but this was caused by the slow shaking of the ground.

If it weren't for the fact that there was no light source here, this place could be called a paradise, and I saw that there were still some small flower-like plants growing on the rocks next to the pool in the middle, but the night vision devices of the team members couldn't see what color those flowers were.

They originally thought that after coming here, they would see a dragon like the earthly python Jörmungari breaking free, but they didn't expect that what they encountered would be such a "quiet and peaceful" paradise-like scene, but when the team members' eyes looked at the top of the waterhole, the fear in their hearts was hooked out again.

Above the waterhole, four huge iron chains as thick as a road hung above the waterhole, and these chains took on a deep black, probably because of the rust produced in this damp environment that does not see the light of day all year round; Each of the four chains had to be nearly five or six meters in size, one end of the chain was connected to a huge broken shackle hanging above the pool, and the other end extended into the darkness in the distance, it was obvious that these chains could no longer restrain that thing, and the reason why they didn't see the dragon was because the dragon had already broken free from the restraint and left here.

"Tenryu...... Ran away? One of the team members asked in a strange tone.

"This and this...... Let me ask the Queen...... Gong Piqing finished speaking, focusing on his own mind, "Queen, what is the situation?" There's nothing here! ”

After he said this, the scene in front of him changed dramatically, for them, this place is absolutely bleak, there is no light source in this unknown underground space, even the night vision devices of the team members can't play much skill here, and his eyes have mutated again in such a dim environment, this is probably his strongest visual mutation, I saw that the queen seemed to be hanging and made his eyes become clear all of a sudden, It was as clear as if he had suddenly come out of an underground cavern that had never seen the light of day to a resort, and he was bathed in the soft sunlight and the refreshing sea breeze from the seaside standing by the sea and enjoying the sea view......

But all this is just the result of his sudden change in vision, which turns this completely dull environment into a scene like the scorching sun in his eyes!

At this time, his vision was so sharp that he could see the charms engraved on those iron chains, and the iron chains hanging in the air seemed to be engraved with scriptures, and the surface was full of dense spells, which was enough to see how much effort the Extreme Cold Hell had put into restraining the Heavenly Dragon, but now that the shackles had been broken, where did the Heavenly Dragon go?

Thinking about it, Gong Piqing's eyes looked at the deep pool in front of him, this is a deep pool in the real sense, because even he can't see how deep this pool is, this seems to be a bottomless abyss, Tianlong Xing may be in this water, or he may have fled to other places, so when they came here, wouldn't it be equivalent to sending themselves to a dead end?

Even the queen didn't speak after seeing such a scene, along the way they encountered too many strange things that even the queen couldn't explain, if the immortal realm spread now, I'm afraid they would either resist on the spot and wait for death, or they could only jump into the deep pool in front of them to escape.

But what are they really afraid of, just when they were confused about the situation in front of them, a sharp wind suddenly came from above, Gong Piqing instantly raised his head, with the help of his super eyesight, he saw that at the top of the cave that was three or four hundred meters high from them, the dark green realm was spreading from above, and countless immortal ghosts occupied this place with the help of the spread of the immortal realm, they were like an invasive creature with a chirping sound from the moment they appeared, this was originally "quiet and peaceful" The underground space was immediately filled with their screams.

Their voices scraped the eardrums of the team members like a claw, and the night vision devices of the team members could not be seen at such a distance, but the more this invisible fear was, the more it could destroy a person's mind, and the team members looked up in fear, but the vision given to them by the night vision devices could barely let them see the iron chain above the deep pool, and they couldn't see the arrival of the immortal realm and the immortal ghosts at all!

"Tell everyone not to panic, your weapons are capable of inflicting damage on immortal ghosts, so that everyone is ready to fight!" The queen's order appeared from Gong Piqing's mind, and Gong Piqing subconsciously picked up the laser gun and conveyed the queen's order truthfully.

With the gradual expansion of the immortal realm, more and more immortal ghosts came to this huge underground space, their eyesight seemed to be able to compete with Gong Piqing, after discovering that their prey was below, they all screamed and climbed up the four huge chains, almost each chain can lie on a dozen or twenty or even more immortal ghosts, they can obviously fly down, but it seems that they are deliberately enjoying this scene of watching the enemy have no way to escape.

As more and more immortal ghosts attached to the four chains, the four chains even shook in the end, and in an instant, the chains, in the air, on the top of the cave and on the side of the rock walls, all were occupied by countless immortal ghosts, Gong Piqing They had never thought that their enemies would have so many, but they also had to watch more immortal ghosts appear around them as the immortal realm spread......

The sound of the four chains shaking echoed from this huge underground space like a kind of magic spell, and the team members all raised their weapons after receiving Gong Piqing's order, and they all brought weapons from that room in their hands, but except for the team member who carried the dragon's spine heavy cannon who actually used these weapons, the others did not fire a single shot, they all hoped that the weapons in their hands did not have any bells and whistles, otherwise they would not be able to afford these costs in the event of an accident.

"Fire!"

"Fire!"

The queen and Gong Piqing ordered successively, and in an instant, the firelight illuminated this huge underground space, the most conspicuous of which was the flaming spear emitted by the dragon's spine heavy cannon, in this dim terrain, it was completely a rapidly rising sun; Compared to the red laser gun in Gong Piqing's hand, the red laser was too small, and even one of the team members carried it on his shoulder, like a quadruple high-velocity heavy gun, every time he fired, four bright light bullets flew out of the muzzle of the gun and flew forward, and the soldier's body was also trembling by the recoil of the heavy artillery.

It seems that the weapons of the Demon Realm are not so bells and whistles, at least they can fire normally, which is enough.

They all originally thought that the queen wanted to use the Celestial Dragon to deal with the Immortal Legion, but who would have thought that the Celestial Dragon had already run away? Or did this behemoth only know how to sleep, and as soon as the restraints were untied, he went back to sleep in the pool under him?

If that's the case, it's really a lazy dragon, but Gong Piqing wants to say to it, do you remember how you woke up last time? Right! That's right! It's someone fighting on your doorstep! Now that a scene from many years ago has reappeared, is it familiar to you?

Thinking about it, his gaze turned to the immortal legion above his head again, although too many things he had experienced along the way exceeded their expectations, but they were really determined to die at this time, since there is no Tianlong, then take this place as the final battlefield, we are no longer the squad that has run out of ammunition, even if we really can't fight, but we also have the strength to fight to the death! We're not going to sit still!

In an instant, this huge underground cavern was as bright as day, countless immortal ghosts burning with dazzling flames fell from the sky, and even the four iron chains were ignited by the flames of the flame spear erupted, and the hot iron began to flow down the iron chains, and it seemed that even such a huge iron chain could not withstand the scorching heat of the bright flames, and it would not be long before they fell into the deep pool below.

The Immortal Realm was once again disturbed by the heavy firepower and stopped spreading, and the number of Immortal Ghosts in the air was drastically reduced, but there were also countless Immortal Ghosts who were avoiding their firepower, and the barrage of fire came around the edge, and they showed their claws and fangs, as if to say that this group of little rats who had been on the run for so long finally had no way to escape this time......
