Judging from the ruins of the surrounding walls, the city has been destroyed for more than a hundred years. Gao Tian couldn't help frowning as he looked at these broken walls.

It seems that the harm of alien beasts is not as easy as those 'bricks' and 'beasts' say. Otherwise, it should be the human race that pushes into the wilderness area, rather than abandoning the city and retreating step by step.

Yes, it is not possible for any government to articulate the specific danger so as not to cause panic, especially of this great danger. Gao Tian can be said to have reached the top for so long in vain, and his emotional intelligence is not ordinarily poor, so he doesn't even know this.

The ruins of the entire city were dead silent, and there was not the slightest sound. Most of the troops in the green alert area are the base's military maintenance and cleaning work, and most of the mercenaries are formed into squads and go to the orange alert area to hunt. As for the green alert zone, few people stopped.

After all, beasts of the first to third grades were not worth much at all, the price was not much different from that of the livestock raised, and almost no one would risk their lives to come and hunt them.

Gao Tian looked at the thick clouds in the sky, and couldn't help but shake his head when he remembered the bright sun when he came out before. This has always been the case in the Warning Zone, and even more so in the Wilderness Zone. As for the reason for this, Gao Tian didn't know at all.

As for those strange phenomena in the sky, not only the high heavens, but also many old mercenaries. Perhaps only those experts who have studied these phenomena, as well as those at the top of the federal hierarchy, know the exact reason.

Gao Tian ran quickly down the road, moving without making a sound, like a ghost, from one shadow to another. In this kind of place where danger may be encountered at any time, Gao Tian is still very careful.

It's just that being careful is being careful, and Gao Tian is not so nervous. He has encountered thousands of battles in the past, and now although he may encounter danger everywhere in the warning area, there is always no battle array, arrows flying, bullets raining, and the battlefield where thousands of lives die at every turn is dangerous and unknown!

Suddenly, Gao Tian's eyes suddenly turned, casting him into a shadow not far away.

"Knock knock knock......" Heavy footsteps came, and in the shadows not far away, a black shadow slowly walked out, and a pair of blood-red eyes lit up in the night.

It was a one-horned bison beast with black hair like black steel thorns, and a dark gray horn like a sharp knife. In the evening sunset, the one-horned sharp knife reflected the cold light. The cold light flickered and was extremely sharp. A pair of bull's eyes were red, full of the smell of killing. It was the size of an armored car, and the ground shook slightly as it walked.

One-horned black rhinoceros!

The one-horned black rhinoceros feels like a heavy Humvee, savage, fierce and swift. The dark gray horn on its forehead can easily pierce ordinary F-grade alloys, which is very terrifying. An ordinary fourth-level martial artist is not its opponent at all. Even if it is a fifth-level martial artist, he may not be able to deal with it. If you're not careful, it's easy to die under its horn.

Gao Tian's brow jumped, this is a strange beast. Moreover, it is also an extremely terrifying existence among the fourth-level strength beasts. Being able to encounter a strange beast of this level in the green alert area, Gao Tian's luck was not ordinarily bad.

The one-horned black rhinoceros has long sensed the existence of the high heavens, which is the survival instinct of the alien beasts in the wilderness area, and can sense information different from that in the wilderness area. Moreover, the perception ability of the alien beast is far beyond that of ordinary beasts, and it has extremely strong aggression. Its scarlet bull's eyes flashed with ferocity, and with a low roar, the one-horned black rhinoceros pressed its head down, and its four hooves moved, and it rushed over with a bang, and the dark gray horn in the darkness flashed with a shining cold light.

As the one-horned black rhinoceros charged, the ground continued to shake in a small area. It was as if a large armored vehicle was coming head-on, enough to crush all obstacles in front of it.

Seeing this, Gao Tian flashed lightly and quickly dodged away.

"Boom!" There was a muffled thud and dust was flying. The broken wall behind Gao Tian was like paper paste, and it was instantly hit by a rhinoceros horn and a gap was opened.

The moment Gao Tian dodged, he immediately rushed towards the one-horned black rhinoceros and appeared on the side of the one-horned black rhinoceros. At this time, Gao Tian did not pull out the Dawn Gun, but used his strength in the palm of his hand, and his palm was like flying, and more than ten palms in a row slapped it fiercely on its body, one palm faster than the other. With the swift force, the rhinoceros was immediately knocked sideways, and its huge body crashed into the ruins, splashing up bursts of dust.

"Roar!"

Gao Tian looked at the ruins with a serious expression and waited intently for a long time. Suddenly, the roar of a one-horned black rhinoceros was heard from the ruins. Listening to the sound, it seems to be wounded.

"Boom!"

A loud explosion erupted from the ruins, and sand and stones flew everywhere. The one-horned black rhinoceros swooped out with red eyes. It walked with its thick four hooves, its head lowered, and the dark gray horn on its forehead flashed with cold light, and it stabbed fiercely at the high heavens again.

This one-horned black rhinoceros is worthy of being an extremely terrifying existence among the fourth-level strength beasts, and it has been slapped by the heavens for more than ten times in a row, and it can actually get up. Although Gao Tian did not use the true power of martial arts, he only struck with the power of **. However, the one-horned black rhinoceros's defense was terrifying, which still made Gao Tian frown.

A fourth-level strength alien beast has such a terrifying defense, so what about those **-level alien beasts? And what about the innate beasts?

Thinking of this, Gao Tian also frowned at the terrifying nature of the strange beast that he had underestimated when he came before.

Feeling the strong wind blowing in his face, Gao Tian did not dodge, but rushed up directly, grabbed the horn of the one-horned black rhinoceros with his right hand, and forcibly withstood the huge impact of the one-horned black rhinoceros.

"Roar...... Roar...... Roar! ......" The one-horned black rhinoceros kept calling, but it couldn't do anything, and was slowly pushed back by the high heavens. Its thick hooves left four deep marks on the earth.

"Give it to me!" Gao Tian roared, his right arm exerted force, and his muscles suddenly tensed. He grabbed the horn of the one-horned black rhinoceros and lifted the one-horned black rhinoceros up. Then, Gao Tian grabbed the horn of the one-horned black rhinoceros like a fly and slapped it around.

"Click! Click! Click! ......" With the sound of crisp bones shattering, the bones of the one-horned black rhinoceros showed unnatural bending, and the huge cow's mouth was bleeding nonstop.

In the end, Gao Tian threw it casually, and the huge body of the one-horned black rhinoceros continued to castrate because of inertia, and flew forward for dozens of meters before stopping.

At this time, the one-horned black rhinoceros has long been dead.
