The sky was covered with clouds and gradually became darker. The corpse groups in the wild became a little manic and kept roaring. After receiving the system warning, players in the wild did not dare to stay in the wild after seeing the changes in these corpse groups. They all ran towards the city.

When Liu Gan and Liu Ruyan ran to the vicinity of the Qingzhu City protection cover, there were no other players outside the city, just like they usually were late at night.

At this time, the sky had completely darkened. The darkness that was about to pour out, even a faint sound of thunder sounded from the far sky.

"Damn it! It's going to rain? It seems that since we were trapped into the game, it has never rained here!"

"Yes! I thought there was no weather system in this game world, and the sun shone brightly every day!"

"What is the era of catastrophe? I'm so looking forward to it!"

"It probably isn't a good thing. Don't look forward to it. I want to upgrade to level 7 today! It's so annoying!"

"You really can't go out? What exactly will happen?"

The players who had been scamming monsters outside and returned to the city gathered in the protective cover, watching the situation outside and talking a lot.

Liu Gan and Liu Ruyan have also returned to the protective cover and found a place to stop. The protective cover is now crowded with people, and they all looked curiously in the direction of the wild, waiting for the system to give them some surprises.

"What will happen?" Liu Ruyan also expressed curiously.

"I'm afraid it's not a good thing." Liu Gan shook his head in the direction of the city.

Since entering the trembling world, Liu Gan has almost never had a few days of stable life. Qingzhu City is now very safe. Players are working hard to go to the wild to sweep monsters and money. The timid and not very hard to make progress. Even if they stay in the city, they can survive by finding something to do.

This doesn't seem to be the usual style of the trembling world.

"Look!"

A player pointed to the direction outside the city and shouted.

Other players have also seen that a large number of corpses appeared on the horizon in the distance, and they were running towards Qingzhu City.

This was impossible in the past. There was a magnetic energy expulsion device in Qingzhu City, which emitted a unique magnetic field, making these zombies afraid to get close. Now these zombies seem to be no longer afraid of the magnetic energy expulsion device, or another force driving them out. This force even exceeded their fear of the magnetic energy device, making them rush towards Qingzhu City desperately.

"What does this mean? Are zombies sieges?" Some timid players subconsciously retreated backwards.

"What are you afraid of? With a protective cover, they can't attack!" Some bold players still looked at the group of corpses that were approaching quickly in the distance with interest.

The zombies in the corpse group almost rushed towards Qingzhu City at the speed of sprinting. From the time the players saw them and rushed to the edge of the protective cover, in just two or three minutes, a large number of corpse groups had already arrived at the edge of the protective cover, and they were crazily tearing and biting the protective cover.

This layer is ineffective for players and only blocks zombies. It emits ripples under the attack of zombies. The players subconsciously took a few steps back, leaving a distance of one or two meters between the player and the protective cover.

"I'll tell me? They can't get in!" Some bold players came forward and provoked the zombies in a manic state at close range.

Some players even launched an attack on the zombies through the protection cover, and the attack was effective. After discovering this good thing, some players who did not dare to leave the city on weekdays quickly seized this opportunity to kill the zombies outside the zombies.

These zombies that rushed over were mainly composed of ordinary zombies, semi-elite zombies and elite zombies. Most players who often left the city were not interested in them, but they also joined the attack ranks. First, they were bored, and second,... so many zombies surrounded the city and attacked the protection cover. Will they really destroy the protection cover? It’s better to kill them.

Although there are many zombies, there are more players in the city. The protection cover prevents zombies from attacking players in the city. However, the players in the city can safely attack those zombies through the protection cover. Under the continuous attacks of needy and boring players, the zombies outside the protection cover become corpses one by one, and then turn into balls of black fog and disappear.

An hour passed, and there were fewer and fewer zombies outside, and they were eventually killed by players, and no one was left.

"This is called a catastrophe? It's too boring, right?"

"Yes! It's just to let the zombies from the wild come to attack the city, but there are millions of players in this city. How could it be easy for them to capture them?"

"Let the disaster come more violently! Come on some high-level zombies! Let me upgrade to level 7 and level 8!"

The players shouted, and some even walked out of the protective cover, looked into the distance, and then walked a little further.

There were dense tides of corpse in the distant sky. Although this time the tide was still dominated by ordinary zombies, semi-elite zombies and elite zombies, there were many mutant zombies, and even a small number of black-spot zombies. The scale of the zombies was two or three times larger than the last time.

The player who ran outside the protective cover ran back with a scream. After a while, the corpse tide rushed to the edge of the protective cover again and attacked the protective cover frantically.

"Tank!" A player pointed to the direction in the city and shouted.

"What tank?" The other players looked into the city together.

"It's a chariot! The chariot of the future!"

A team of magnetic levitation tanks appeared on the street in the distance. The hideous metal appearance immediately attracted the attention of players. It was obvious that this was a team of combat vehicles controlled by the NP in the city. They had never appeared before. Now they appeared probably to ensure that the protective cover was not destroyed by the corpse tide outside.

After the magnetic levitation tank came to the protection cover, it lined up along the protection cover, then extended seven or eight energy barrels from the vehicle body and shot at the zombies outside the protection cover. After a while, some chariots rushed to the protection cover, and some rotating alloy blades appeared outside the vehicle body, flashing with energy light and shadow tore the zombies outside the protection cover to pieces.

"I! So cool! I want to have one of this chariots too! It's so efficient to use this thing to kill zombies!"

"You want something that only np has? It's useless to think about it!"

"What do you mean by this catastrophe era? It means that the corpse tide is besieging the city? NP also comes to help with the war? This seems to be the first time the NP army is dispatched?"

Players watched the NP tanks and started talking.

Liu Qian mingled among the players and quietly approached one of the chariots. (To be continued.)
