"Why do you suddenly feel so uneasy?" At the same time as the underground space underwent a change, Chu Xun's heart also tightened suddenly, as if something very terrible was about to happen.

"What's wrong?" Seeing Chu Xun suddenly stop and show a solemn expression, Yang Lang and Xue Wan'er's faces also changed in unison, and they became vigilant.

"I don't know why I always feel a little uneasy, as if something terrible is about to happen." Chu Xun shook his head, and then said with a solemn look in his eyes: "Everyone should be careful, it is very likely that something unexpected will happen." ”

"Could it be that you're too nervous?" Yang Lang frowned slightly, looked around, and then asked with some puzzlement.

"No, my instincts are very sharp, as long as I have a premonition of danger, there is basically nothing wrong." Chu Xun took a deep breath, clenched his fists, and then continued to walk forward, and said in a deep voice: "No matter what, everyone should be careful, if we really encounter any big trouble, then we will retreat immediately!" ”

"Good!" Seeing Chu Xun's serious expression, Yang Lang and Xue Wan'er didn't dare to have any doubts, they nodded one after another, and then followed behind Chu Xun left and right, moving forward carefully.

Boom Boom Boom!

Facts have proved that Chu Xun's premonition was not wrong, and just as the three of them were marching forward on guard, a violent roar suddenly sounded from the ground, and then the entire ground began to tremble violently.

In the next second, the central control base in the center of the city, which had been reduced to ruins, suddenly cracked several huge holes, and then countless mutated insects surged out of the gap like a blowout.

In addition, insects all over the city, both nocturnal and diurnal, went completely crazy, and then poured out of their nests and converged towards the center of the city.

In the blink of an eye, the sky over the entire dead city was instantly occupied by countless flying insects, and even the rising sun was obscured by the sea of insects, plunging the entire dead city into darkness. At the same time, the ground also began to be quickly covered by a sea of black insects, and the momentum was so great that it was overwhelming and terrifying.

"Retreat!" Although it was not close to the city center, Chu Xun and the others could still clearly see the overwhelming sea of insects. Looking at the "insect cloud" in the sky that almost covered the entire dead city, Chu Xun's face suddenly changed drastically, and then he turned around and shot towards the place where the battle fort was.

And Yang Lang and Xue Wan'er's faces also became extremely pale, and they didn't need Chu Xun's reminder at all, so they followed Chu Xun and rushed towards the battle fort.

The scale of such a terrifying sea of insects is far beyond the scope of their ability to deal with it, and if they don't retreat at this time, it will undoubtedly kill themselves.

Just running wildly, Chu Xun's heart was also full of doubts.

Why did these bugs suddenly become so violent, even with the whole army out of action? And if he was not mistaken, many of those mutant insects flying in the sky are nocturnal, and now that the sun has risen and the sun is shining, it stands to reason that these insects should already be dormant, right?

So, what happened to make these insects change their biological instincts and even dare to come out in broad daylight?

Thinking of this, the uneasy feeling in Chu Xun's heart became more and more intense!

"What's going on?"

At the same time, Chu Madman and the others who were waiting outside the No. 4 Dead City also discovered the changes in the city, but their perception was more acute than that of Chu Xun and the others, so they also sensed the terrifying aura that was gradually awakening in the center of the city.

"Could it be that the demon back then is not dead?" Feeling the terrifying aura that was full of violence and murderous taste, as if they were born to destroy everything, the faces of Chu Madman and the others suddenly became extremely solemn.

Decades ago, the destruction of Baicheng shocked the entire mountain range, and everyone in the nearby cities was in danger, and even Chu Cheng specially purchased that kind of special insect repellent equipment from the Supreme Council, in order to avoid a recurrence of the disaster.

It was also that cruel battle to destroy the city that made everyone understand the horror of the Zerg, and a deeper understanding of the horror of that demon!

It's just that with the self-explosion of the city lord of Baicheng in the end, the demon also fell into the central control base of Baicheng along with a large number of mutant insects, and there was no more news. Later, a strong man came to investigate, but he did not find any signs of the demon's survival, and the matter came to an end. And that terrible demon gradually faded out of people's sight, and finally became a terrifying existence that parents finally frightened their children.

Chu Madman and the others, who were still teenagers at the beginning, naturally experienced that terrible era, so they were deeply impressed by both this dead city and the terrible demon that used to be, so that at this moment, the dead city had changed, and they immediately thought of the terrible demon that destroyed the white city, so that everyone changed color.

"No, I have to go back and report this matter to the city lord, if that demon really doesn't die, I'm afraid it will be a terrible disaster again!" Chu Han, who had always been extremely indifferent, had a solemn look on his face at the moment, and even exuded a terrifying cold aura visible to the naked eye, causing a layer of hoarfrost to form on the ground around him.

Obviously, the appearance of this terrible demon made him really nervous, and he couldn't even control his strength!

"I'll go back and report the news, so that the city lord can get ready. As for the children in the dead city, it's up to you and the magicians, no matter what, you must bring them back, they have a stake in this survival game! Chu madman quickly made a judgment, and then said a word to Chu Feng and Chu Han, then jumped up, turned into a golden light, and disappeared in the eyes of Chu Feng and Chu Han in an instant with a violent sonic boom and terrifying wind that was gliding like a supersonic fighter plane gliding at a speed that was difficult to distinguish with the naked eye, leaving only a broken tunnel as if it had been swept by a tornado.

It was only at this moment that this strongest strong system powerhouse in Chu City showed his true terrifyingness!

"Let's go, activate the positioning system, let's go find them!" The stakes were very high, and Chu Han and Chu Feng didn't dare to slack off, they glanced at each other, then nodded, and activated the positioning bracelet on Chu Xun and the others.

Suddenly, the positioning bracelet on the hands of Chu Xun and the others also trembled slightly, making a buzz, and in the next second, Chu Han's cold voice also sounded from the bracelet: "Things have changed, the student assessment is temporarily suspended, all the students will find the nearest fortifications for defense, Chu Feng and I will find you as soon as possible!" Remember, try to survive! ”

"What?"

Hearing the sound in the bracelet, the faces of the few remaining participating students in Chu City became extremely ugly.

was able to make Chu Han Chu Feng interrupt the student assessment and personally help, obviously, the horror of this change has far exceeded their imagination!

And among all of them, the one whose face changed the most was Chu Xun, who had already felt the danger before.

However, the reason for the drastic change in his face was not because of Chu Han's words, but because of the voice that suddenly sounded in his head.

At this critical moment, the Super Savior System, which had been silent for a long time, actually released a new mission again!

"Drop, the host triggers the world's mission - the revival of the worm demon!"
