At 1 a.m., at the Third Institute of Anxi City, the cage where the mutant dog on the west side was located, there was a mutant dog in the cage that had begun to slowly change. It was the mutant dog that had been enjoying the wild game provided by Cheng Yuxing. It had accumulated enough spiritual energy tonight and it was about to break through to the Qi Refining Period.

As long as it can break through to the Qi Refining Stage, with its own cultivation level, it can easily break through the defensive facilities here. These mortals will definitely be vulnerable in the face of its greatly increased spiritual consciousness. If the spiritual consciousness had not been able to affect only a few people in the past, these extraterritorial demons in the innate stage would have long since escaped here.

At one point, when the research institute started to be sparsely crowded, the innate extraterritorial demon began to break through. In an instant, the black air in the cage where it was located was rippling, and the alarm inside the cage immediately rang wildly.

When all the researchers heard the alarm sound, they quickly evacuated. When the guards saw that there were alarms on the mutant dogs, they immediately approached carefully at the place where the sirens were, and they knew how powerful the mutant dog that escaped from the cage a month ago was.

Half of the guards in the entire institute died that day under the attack of the mutant dog. If it weren't for the laser network, they might not have been able to kill the mutant dog. Today, the mutant dog had an accident, and the monitor could not see clearly what was happening inside, so they could only approach carefully.

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

All the guards immediately fired, but something that made them desperate happened. The bullet was completely bounced away by the black gas from the mutant dog. Before the guards could react, the mutant dog had already rushed to the middle of them. With the arrival of the mutant dog, a bloody storm floated up in the middle of the guards, and all the squad 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 cold look 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 Institute at full speed.

What this extraterritorial demon didn't expect was that the spiritual energy on the earth was so thin that it was outrageously thin. Even if it broke through the Qi Refining Period, it was not able to absorb enough spiritual energy when it broke through. Therefore, even if he broke through to the Qi Refining Period, his magic power was too small, and he was only enough to use a few useless curse techniques. If he wanted to escape here, he had to rely on his innate cultivation.

In fact, the most deadly thing is that just now a group of troops retreated to the suburbs of Anxi City for rest and rest. The Third Institute is not far from the garrison of these troops. After receiving the highest warning from the Institute, the highest leader of the Institute thought of the army not far from their Institute. He called the army command center and asked them to provide help. He knew how powerful the mutant dog that wanted to escape from the Institute was.

In less than 5 minutes, the army's armored vehicles drove to the gate of the institute. As soon as the defense line was laid, the soldiers heard the fierce gunfire and screams before the tragic death of the personnel. All the soldiers were full of energy.

A platoon of soldiers rushed in through the gate opened by the institute, striving to kill the mutant animals in the institute and rescue the trapped guards inside.

Not 100 meters after entering the institute, a black shadow rushed into the group of soldiers at an extremely fast speed, and instantly caused a bloody storm. A large number of soldiers were killed by mutant dogs. Other soldiers who were not attacked immediately formed a defensive front and began to pour their bullets into the shadow.

But they encountered the same problem as the guards of the institute. Their bullets had no effect on the mutant dogs. Only their grenades could defeat the mutant dog from time to time so that it could not get close to them. Otherwise, their current fate would definitely be the same as their dead comrades on the other side. However, even so, most of the soldiers were already scarred.

The platoon leader immediately called for support and reported the details of the situation inside to the superiors, requiring the support unit to come with heavy weapons, otherwise, these mutant dogs would never be able to be eliminated. He just saw at least three mutant dogs.

Zhen Aiguo looked at the report submitted 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. Grenades and other things could only repel them, but they could not kill them. It seems that there are good things in this research institute, but why did he encounter such things?

Today, I happened to have these mutant dogs to relieve my depression two days ago. Zhen Aiguo's body had completely recovered under the treatment of Zhao Chaogang's medicinal wine. The Commander-in-Ship Hall did not put the blame for defeat on him. There was a senior executive in the secret realm of the martial arts world who admired Zhen Aiguo very much, so Zhen Aiguo did not retreat 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 looked like? They had such powerful combat power. If possible, he would not mind that his army could have such powerful combat power.

When Zhen Aiguo came to the institute, he looked at the battle scene with a little disbelief. The soldiers of a company helped by five armored vehicles were just the general to block the attack of the mutant dog. If the institute had not been deep underground and the passage to the ground was only a five or six-meter-wide door, they might have been defeated now.

Zhen Aiguo also saw that the mutant dog was powerful. The mutant dog was able to survive 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. Zhen Aiguo's brows were a little frowning for such a scene.

This scene is really a bit similar to the artillery battle a few days ago. The institute has actually developed such a powerful mutant creature. It really opened his eyes. I don’t know how long it will take to form combat power. However, the most important thing now is to eliminate these mutant dogs as soon as possible. If they are allowed to escape, the consequences will be unimaginable.

Zhen Aiguo actually has a way to eliminate the mutant dog. When he was watching the battle scene of the mutant dog, he had noticed a detail. After the black gas on the mutant dog was attacked by large-caliber bullets or grenades, the black gas on its body would dissipate greatly, and the mutant dog would immediately hide in the research room. When it came out, the black gas on its body would recover.

It seems that the black gas on the mutant dog is the main reason why it has such a strong defense. This is easy to deal with. Zhen Aiguo directly transferred a few tanks into it, all of which were equipped with high-power armor-piercing bombs, waiting for his unified order.

Zhen Aiguo's eyes were always staring at the video in front of him. Just now, a black shadow flashed in the video. Zhen Aiguo ordered the shooting directly. Suddenly, five powerful armor-piercing bombs directly hit the mutant dog with black air. The effect of this fire-intensive attack was also very good. The black air on the mutant dog had disappeared.

The armored vehicle also seized this opportunity and suddenly a burst of fierce artillery fire attacked the mutant dog. The demons from the outside world looked at the various ammunitions getting closer and closer, and their eyes showed a look of fear for the first time.

If I hadn't just broken through the Qi Refining Stage and had not had much spiritual energy on my body, and I could not have cast spells, how could these mortals hurt me? But I wouldn't have made you happy if I die. The demons from the outside world tried their best to cast the only spell he could cast now: the Plague Curse.

With a "bang", the entire mutant dog split into pieces under the powerful firepower, and all the soldiers screamed excitedly, but they did not see a burst of black gas dissipating in all directions with the smoke of the shells. This is the plague curse technique used by the demons outside the territory before their death. The disaster in Anxi City is about to come.

It took five hours for the army to destroy the five mutant dogs that escaped from the laboratory. It didn't take such a long time, but after seeing the death of the mutant dog in front, they all hid in the laboratory and refused to come out again.

In the end, I had to completely open the door of the laboratory and let the tanks and armored vehicles enter. Fortunately, the underground height of the laboratory is enough, otherwise, it would take more time to eliminate these mutant dogs.

Zhen Aiguo looked at the last mutant dog that had died in front of him, and a little sweat broke out on his head. The strength of the last two mutant dogs was surprisingly powerful. Just looking at the two scrapped tanks, you can tell how powerful these two mutant dogs are.

The tank that was just hit by these two mutant dogs was the main battle tank in the army. However, an alloy guy weighing more than 50 tons was torn apart by the claws of the two mutant dogs. This scene surprised Zhen Aiguo a little. He didn't expect that such a powerful mutant dog could be developed in the domestic research room. Anyone who could see such a powerful mutant dog would be happy.

Well, Zhen Aiguo is already considering sending a report. When specific control measures are taken in the future, he will provide his troops with some obedient mutant dogs.

In fact, the object that Zhen Aiguo and the others were completely wrong. After absorbing enough souls, these two mutant dogs burned violently the souls that they had just absorbed and had no time to digest, so that they could gain relatively powerful power in a short period of time. Unfortunately, the souls of ordinary people who have not practiced can provide them with too little soul energy. After only half a minute of their power, they were killed exhausted.
