Among the countless brass arms and iron pickaxes that rose one after another, Gong Piqing's entire world was stained a bloody red, and the iron pickaxes that frequently fell seemed to destroy not his body, but the whole world.

Yes, the whole world was shattered by these mechanical miners and iron pickaxes, and Gong Piqing felt a violent shaking on the ground below him, and it felt like people were lying on the ground and were about to be shaken.

The tunnel collapsed, and the boulders falling from the sky smashed the mechanical miners again, and the figure of the Hades did not know when it had disappeared from Gong Piqing's eyes, or rather, the impact of the collapse of the world on Gong Piqing had surpassed that of the Hades.

"It's coming! It's here again! Fast! And there are no heavy weapons, and there are no heavy weapons! ”

Gong Piqing wondered if he had heard it wrong, and at this time, he actually heard the panicked cry of a human being.

"Heavy weapons?! Gone! There's nothing here! Ordinary weapons can't hurt it at all! We don't have any heavy weapons anymore! ”

"Yes! Yes! We have heavy weapons, Hades hasn't returned, the World Tree is unconscious, and we've got Gaia! ”

"That's right! We still have Gaia! Get Gaia out there, with Gaia we can defeat this monster! ”

……

Gong Piqing didn't know what he was going through, and he didn't know what these people were shouting, what was a ghost and Gaia? Could it be that the ghost and Gaia came to save him?

In the next second, there was a sound of steel colliding with the ground, Gong Piqing only felt a sharp pain in his stomach and legs, and his whole person suddenly woke up, he opened his eyes suddenly, and saw a huge iron cabinet that didn't put much on him, because the iron cabinet had just fallen, and the bottles and cans in the cabinet had not had time to roll out, and there was a noisy rolling sound in the cabinet.

In the end, Gong Piqing watched those large and small medicine bottles roll down from the iron cabinet to the ground, which were nothing more than some anti-inflammatory drugs and painkillers, and if he remembered correctly, some of these things seemed to be brought back from the outside.

If it weren't for these medicines, I'm afraid he wouldn't have known that he was back in the Mill Institute now, and the fact that the Hades had just been possessed by the mechanical lords and let so many mechanical lords kill him was actually just a terrible dream.

"The alert distance has been refreshed again! The alert distance has been refreshed again! Ten meters! Ten meters! Don't be within 10 meters of it! Within ten meters is its suppression range, be sure to stay away from it! If you don't have a weapon, run, you don't need your help in this battle! Fight if you can, run if you can't! No more senseless sacrifices! ”

"I'm sorry! Top dog! I'm sorry, I really can't beat this thing, I'll go first, I'm sorry guys! I want to live, I really want to live! ”

"Boss! I'm gone, too! I don't have a weapon! I can't beat it! I don't want to be a burden to you! I will be your soldier in the next life! ”

The noisy shouts made Gong Piqing confused, he didn't understand, what was going on outside? Isn't this the Mill Institute? How did it get so messy?

Also, if it's the Mill Institute, the people who shout these words should be the staff of their Mill Research Institute, but what do they mean by shouting this? What can't be beaten?

It wasn't until a sharp sound of breaking wind came that Gong Piqing's heart had a hint of familiarity.

The voice was really familiar to him, but for a moment he couldn't remember where he had heard it; He could only barely remember that it sounded like the sound of something flying at high speed.

But what could it be that could fly at such high speed inside their Mill Institute?

There was another shaking as if the sky was falling apart, and this time, Gong Piqing didn't escape, but was thrown off the bed directly by this shaking.

The sharp pain in his chest made Gong Piqing completely sober, his pupils suddenly contracted, and his eyes underwent an advanced level of night vision mutation in order to adapt to the dark light environment, and at the same time, the pain on his body made him enter a combat form that favored defensive mutations, and the thickened exoskeleton seeped out from under the skin and quickly replaced the skin, and at the same time, many sharp spikes grew on the exoskeleton for deterring and counter-injuring enemies.

But when he looked up and saw the huge figure that crossed the dark blue night sky, even he was stunned.

W-This is the dragon they had dealt with in the wasteland on the outskirts of the city?! When did this monster come back to life?

Gong Piqing rubbed his eyes meaningfully, because he really couldn't believe that it could be true.

How can it be...... At the beginning, he personally rode on the dragon's neck and smashed the dragon's head with his mutant weapon!

When he killed the dragon at that time, he couldn't even stand the bloody scene, even if the dragon had enough self-healing ability comparable to a "medical miracle", it was almost impossible to resurrect it......

But the scene in front of him also told Gong Piqing at all times that what he saw was true, the Mill Research Institute was attacked by the dragon, and the dragon's methods were extremely cruel, just like when he was in the form of a dragon, he directly pierced through the three layers of ground and flew into the Xiguan Renai Research Institute to destroy it.

Gong Piqing subconsciously felt that this would be the killer sent by the Xiguan Renai Research Institute to take revenge on them, after all, the way this dragon invaded was too similar to him.

If you have to find out any difference from these two research institute attacks, it can only be said that the Xiguan Renai Research Institute is hidden in the third basement floor, and their Mill Research Institute is hidden in the second basement floor, and it is much more difficult to invade Xiguan Renai than to invade their Mill Research Institute, which can prove that Gong Piqing in Nidhogg's form is stronger than this giant dragon.

But this is just a meaningless comparison made by Gong Piqing from his heart, because even if he is stronger than this dragon in his Nidhogg form, how can he say that he can change now?

The highest enhanced dragon-shaped mutation almost took his entire physical strength to complete once, and now he was in that state of exhaustion of "running out of oil and running out", he couldn't just say that it would explode as before......

"Quick! We're completely out of ammo and we're left with Ghosts and Gaia! What's going on over there in Gaia?! Another person's hurried shout reached Gong Piqing's ears.

"But Gaia's own life is in danger, and without that device, he may not even survive a day!"

"But without Gaia, all of us might not have survived tomorrow!"

There was a moment of silence in the battlefield in the silent night, except for the sound of the dragon gliding through the air.

"Good...... I know...... I'm ...... Call him ......"

After that, Gong Piqing heard the sound of the staff walking hurriedly towards the intensive care unit.

The next attack of the dragon struck, and the research institute shook violently again, a large number of building fragments fell from above, such an attack, almost every attack came, many staff members were injured, but the unique underground structure of the research institute was not a cage at this time, a cage that trapped most of their lives.

Perhaps for the entire Mill Institute and the people in the Mill Institute, their only way to survive is the ghost and Gaia in the mouth of the man just now.

But...... Gaia......

Gong Piqing felt as if his head had been smashed, and he always felt that Gaia could not set foot on the battlefield.

Yes, Gaia can't set foot on the battlefield, and even the man said that if Gaia joins the battle, he may not even survive tomorrow.

But has this dragon really pushed their Mill Institute into such a desperate situation......
