At 1 o'clock in the morning, the third research institute of Anxi City, the cage where the mutant dog on the west side is located, there is a mutant dog in the cage that has begun to slowly change, it is the mutant dog that has been enjoying the game provided by Cheng Yuxing, it has accumulated enough aura tonight, and it is about to break through to the qi refining period.

As long as it can break through to the Qi Refining Period, with its own cultivation, it can easily break through the defenses here, these mortals will definitely be vulnerable in the face of its greatly increased Divine Sense, if it wasn't for the fact that the Divine Sense could only affect a few people, these Innate Extraterritorial Heavenly Demons would have fled here long ago.

At ten o'clock, when the inhabited population in the research institute began to be sparse, this innate extraterritorial heavenly demon began to break through, and in an instant, the black air in the cage where it was located was rippling, and the alarm in the cage immediately sounded wildly.

As soon as all the researchers heard the siren go off, they quickly evacuated, and the guards saw that there was an alarm in the place where the mutant dogs were kept, and immediately approached cautiously where the sirens were located, but they knew how powerful the mutant dog escaped from the cage a month ago was.

Half of the guards of the entire research institute died under the attack of the mutant dog that day, if it weren't for the effect of the laser net, they might not have been able to kill the mutant dog, and today the mutant dog had an accident, and the monitor couldn't see what was going on inside, so they had to approach cautiously.

Just as the guards were about to approach the cage where the mutant dog was, a loud noise came from inside the cage, and then they saw a mutant dog covered in black gas rush out of the cage and quickly rush towards them.

All the guards immediately opened fire, but to their despair, the bullet was completely bounced off by the black gas on the mutant dog. Before these guards could react, the mutant dog had already pounced among them, and with the arrival of the mutant dog, a bloody storm floated among the guards, and all a small team of 12 guards were torn to pieces by the mutant dog in just a few seconds.

Looking at the bloody scene inside the monitor and the indifferent eyes of the mutant dog, the guards outside directly rang the alarm bell of the highest alert, and all the researchers and clerks evacuated the third research institute at full speed.

And what this extraterritorial heavenly demon didn't expect was that the aura on the earth was outrageously thin, even if it broke through the qi refining period. But he was actually unable to absorb enough aura when he broke through, so even if he broke through to the qi refining stage, his mana was too little, and it was only enough to cast a few useless curse spells. If you want to escape from here, you have to rely on your innate stage cultivation.

Actually, the worst thing is. The troops of one of the armies had just withdrawn to the outskirts of the city of Anxi for rest. The third research institute is not far from the garrison of these troops, and the top leader of the research institute after receiving the highest warning from the research institute, he thought of the army not far from their research institute, and he called the army headquarters with a phone call and asked them to help, but he knew how powerful the mutant dogs who wanted to escape from the research institute were.

Within 5 minutes, the army's armored vehicles drove to the gate of the research institute, and as soon as the defensive line was arranged, these soldiers heard bursts of fierce gunfire and screams before the tragic death of the personnel from inside the research institute. All the soldiers cheered up the spirits.

A platoon of soldiers burst through the open door of the research institute, trying to kill the mutant animals inside the research institute and free the trapped guards inside.

Just entered the institute less than 100 meters, a black shadow rushed into the group of soldiers at an extremely fast speed, instantly set off a bloody storm, a large number of soldiers were killed by mutant dogs, and the other soldiers who were not attacked immediately formed a defensive line and began to pour their bullets at the black shadow.

But they encountered the same problem as the guards of the institute, their bullets had no effect on the mutant dogs at all, only their grenades could still repel the mutant dogs from time to time, so that it could not get close again, otherwise, their current fate would definitely be the same as the dead comrades on the other side, but even so, most of the soldiers were already scarred.

The platoon commander immediately called for support, and reported the details of the situation to his superiors, asking the support unit to come with heavy weapons, otherwise, these mutant dogs would never be eliminated, and he saw at least three mutant dogs just now.

Zhen Aiguo looked at the report handed in by the communications office, and after reading it, he couldn't believe it, the mutant dogs he encountered in a research institute were immune to all light weapons, and the gun grenade or something could only repel them, but they could not kill them.

Today, I just took these mutant dogs to kill my depressed mood two days ago, Zhen Aiguo's body has fully recovered under the treatment of Zhao Chaogang's medicine and wine, and the commander-in-command hall did not put the responsibility for the defeat on him, but there is a high-level person in the martial arts secret realm who admires Zhen Aiguo very much, so Zhen Aiguo did not retire from illness.

Zhen Aiguo directly ordered a tank company to go to the research institute to deal with these mutant dogs as soon as possible, and Zhen Aiguo also went with him, he wanted to see what these mutant dogs were like? There was such a powerful combat power, if it was possible, he didn't mind that his army could also have such a powerful combat power.

When Zhen Aiguo came to the research institute, he was a little afraid to look at the battle scene in front of him with confidence, the soldiers of a company with the help of five armored vehicles were only going to block the attack of the mutant dogs, if it weren't for the fact that the institute was deep underground, and the passage to the ground was only a door five or six meters wide, and now they might have been defeated.

Zhen Aiguo also saw the power of the mutant dog, the mutant dog was able to survive under the powerful firepower of an armored company, only the large-caliber bullets of the armored vehicle and the grenades in the hands of the soldiers could cause a little damage to it, for such a scene, Zhen Aiguo's brows furrowed a little.

This scene is really a bit similar to the artillery battle a few days ago, this research institute has already researched such a powerful mutated creature, it is really an eye-opener for him, and he doesn't know how long it will take to form combat effectiveness, but the main thing now is to eliminate these mutant dogs as soon as possible, if they are allowed to escape, the consequences are unimaginable.

Zhen Aiguo actually has a way to eliminate the mutant dog, he just watched the battle scene of the mutant dog, he had already noticed a detail, the black gas on the mutant dog will be greatly dissipated after the attack of large-caliber bullets or grenades, and the mutant dog will immediately hide in the research room, and when it comes out, the black gas on the body will be restored.

It seems that the black gas on the mutant dog is the main reason why it has such a strong defensive power, so it will be easy to do, Zhen Aiguo directly transferred a few tanks, all of them were reloaded with high-power armor-piercing bullets, and waited for his unified order.

Zhen Aiguo's eyes were always staring at the video in front of him, just a black shadow flashed in the video, Zhen Aiguo directly ordered to shoot, and suddenly 5 high-power armor-piercing bullets directly hit this mutant dog covered in black gas, and the effect of this concentrated fire attack was also very good, and the black gas on the mutant dog had disappeared.

The armored car also seized this opportunity, and suddenly a fierce artillery fire attacked the mutant dog, and the extraterritorial heavenly demon looked at the various ammunition that was getting closer and closer, and for the first time it showed a look of fear in its eyes.

If it weren't for the fact that I had just broken through the Qi Refining Period, I didn't have much aura on my body, and I couldn't have been able to cast spells, how could these mortals hurt me, but if I die, I won't let you have a good time, and the Extraterritorial Heavenly Demon did his best to cast the only spell he can cast now: the Plague Curse Technique.

With a "bang", the whole mutant dog was torn apart under the powerful firepower, and all the soldiers screamed excitedly, but they didn't see a burst of black gas disperse in all directions with the smoke of the cannonballs, this is the plague curse technique cast by the extraterritorial heavenly demon before he died, and the catastrophe in Anxi City is coming.

It took five hours for the army to eliminate the five mutant dogs that escaped from the research room, and it didn't take such a long time, but after the next few saw the death of the mutant dog in front of them, they all hid in the research room and refused to come out again.

Zuihou had to completely dismantle the door of the research room and let the tanks and armored vehicles enter, fortunately, the underground height of the research room was still enough, otherwise, it would really take a little more time to eliminate these mutant dogs.

Zhen Aiguo looked at the dead Zuihou a mutant dog in front of him, and there was a faint sweat on his head, the strength of the two mutant dogs just now was really unexpectedly strong, look at the two scrapped tanks, you can know the strength of these two mutant dogs.

The tank that had just been punched a few big holes by these two mutant dogs was the army's active main battle tank, but an alloy guy weighing more than fifty tons was torn apart by the claws of two mutant dogs, such a scene made Zhen Aiguo a little surprised, I didn't expect that in the domestic research laboratory, such a powerful mutant dog could be researched, such a powerful mutant dog, whoever saw it would be happy.

Well, Zhen Aiguo is already thinking about making a report, and when there are specific control measures in the future, he will allocate some obedient mutant dogs to his troops.

In fact, Zhen Aiguo and the object they were completely mistaken, these two mutant dogs were after absorbing enough souls, and burning these souls that they had just absorbed and had not had time to digest violently, so that they could obtain a relatively powerful liliang in a short period of time, but unfortunately, the souls of ordinary people who had not undergone cultivation could provide them with too little soul energy, and they were killed after only half a minute.
