"Roar, roar, roar!"

The endless beast roar resounded outside Blackstone City, and a large number of mutant beasts rushed towards Blackstone City, and they frantically slammed into the countless arrows raining down.

Flying mutants appeared in the sky, hovering above Blackstone City, looking for a target to attack, but instead of attacking immediately, they waited silently.

Countless mutant beasts came to the city walls, struggling to destroy the Black Rock City, either burrowing into the ground, or climbing, or choosing to attack the fragile gates.

The battle finally started, Qin Tianyu had already taken out his bow and arrows at this time, and stood on the city wall, shooting continuously with one bow and three arrows, each blow could hit a mutant beast and inflict heavy damage on the other party.

In a very short period of time, the mutant beast that is good at climbing rushed to the city wall and started a life-and-death struggle with the professionals guarding here, and the battle of nine deaths finally began.

The big sword in Qin Tianyu's hand swung wildly, easily slashing the monkey-like mutant beast in front of him like a windmill, and the speed was incredible.

These monkey-like mutant beasts are just the most rubbish mutant beasts, in addition to being good at climbing, their strength is no different from ordinary people, so Qin Tianyu is extremely relaxed when facing these mutant beasts.

It's just that there are too many of these monkey-like mutant beasts, and there are hundreds of thousands of them, and under such a number of attacks, even if the strength is ordinary, it has brought tremendous pressure to the guards of Black Rock City.

The frantic battle shows no signs of stopping, and the entire Blackstone City is being attacked in all directions, and endless mutant beasts are raging wildly, intertwining with the guards and professionals in Blackstone City, forming a terrifying battle scene.

Under such an attack, screams, cries for help, shouts, and roars continued to spread throughout Blackstone City.

Countless professionals have fought frantically in blood and death, and no one retreats, because they know that retreat is equal to death.

If Blackstone City falls, then all humans will die.

The battle was going on frantically, the weapons in Qin Tianyu's hands had turned into twin swords, his figure flashed rapidly on the wide city wall, and the two thin swords were like the side of the death scythe that harvested life, slashing mutant beasts one after another.

Around him were countless mutant beast corpses, all of which had died by his sword.

However, the occupations that were originally guarding the city wall and were densely packed around it became more and more scarce and sparse, and the corpses of the professionals slowly increased.

As time passed, more and more professionals died, and Qin Tianyu could feel that if this continued, the city wall would likely be lost.

The figure flickered, the long sword in Qin Tianyu's hand pierced the mutant beast in the form of a mouse in front of him, and then touched the blood on his face, he looked at the mutant beast that climbed up from under the city wall on the other side, and rushed over without hesitation.

Not far behind him, that is, under the city wall, is the Happy Mansion, and his younger sister Qin Yue and younger brother Qin Feng protect those children in the mansion.

So Qin Tianyu can't back down, he has a great responsibility.

"Wow!" A long howl came from the sky, and the flying mutant beasts entrenched in the sky finally began to act.

Countless flying mutant beasts suddenly rushed to the ground at this moment, swooping down with bloodthirsty light.

At this moment, in Black Rock City, countless mutant beasts suddenly drilled out under the ground, and they began to slaughter frantically at the first time.

"Die!" The old man's voice rang out, and then a meteor-like flame shot out towards the sky.

"Boom!" A terrifying explosion swept through the entire sky, and countless flying mutant beasts were devastated at this moment.

A large number of flying mutants are burning, falling from the sky, and life is dying in wailing.

Qin Tianyu looked at this terrifying blow, his eyes shone with shock, according to his speculation, the person who could unleash this attack was at least a professional in the third world, that is, the top powerhouse in this world.

It's just that the screams that kept coming from inside Black Rock City made Qin Tianyu's eyes streak, because a large number of mutant beasts that came out of the ground began to attack the humans in the city, and the pains and screams sounded one after another.

However, Qin Tianyu did not summon his own dinosaurs, because from his God's perspective, he saw the many professionals guarding the city, and they finally started to act.

In their respective areas, they wielded weapons one by one, slashing the mutant beasts in the city and protecting the humans in the city.

Qin Tianyu glanced at the younger brothers and sisters standing in the courtyard of the Happy Mansion, especially the sad and compassionate look on his sister's face, he frowned slightly.

At this time, those children were all hiding in the house, and there were only heavily armed younger brothers and sisters outside the house, although Qin Tianyu didn't know why his sister showed such an expression, but he didn't have time to pay attention to these, because there were a large number of mutant beasts climbing the city wall.

The crazy battle is still going on, on the city walls, in the city, there are shouts of killing, the sound of battle, from time to time there are professionals who die in the battle, and some people want to escape, but the inspector team will kill these fleeing people as soon as possible.

As time passed, the entire city of Black Rock was filled with gunsmoke and blood.

This situation, at the moment when the second wave of beast tides came, reached its peak, and countless professionals died in this new round of battles, including many powerful professionals.

Qin Tianyu gasped violently, his clothes had been torn apart, revealing the black dragon armor inside.

If it weren't for this armor, maybe he would have been drenched in blood and scarred.

Now he couldn't see the scene in front of him clearly, because the city wall was already covered with countless mutant beasts, and Qin Tianyu couldn't care about anything other than using God's perspective to lock on to his younger brothers and sisters in the Happy Mansion.

At this time, a group of professionals who exuded a powerful momentum walked up to the city wall, these people looked as cold as the wind, and their steps were firm into the rock.

They carried a variety of weapons up to the city walls and began to assist in the battle.

"Boom!" A white fist phantom suddenly appeared from Qin Tianyu's side, instantly killing seven or eight mutant beasts that wanted to attack Qin Tianyu.

A white-haired middle-aged professional wearing armor and no weapons easily jumped onto the city wall, and then looked at Qin Tianyu, who was stained red with blood.

"Good job, boy!" The white-haired middle-aged professional walked up to Qin Tianyu's side, patted Qin Tianyu's shoulder and exclaimed.

Because all the professionals in this area were killed in battle, only Qin Tianyu was guarding here alone, and with the power of one person, countless mutant beasts were presented.

"In the back, are my relatives." Qin Tianyu said with a smile, didn't care about wiping the blood off his face, and rushed out again with his double swords.
