Echelon classification shall be carried out according to the ranking of combat power list.

Although the total number of the third echelon reached 20 million, not everyone was present at this moment.

According to the shift rest system, now more than half of the people rest in the city.

The third tier, about eight million people online.

Eight million players, divided into four directions of southeast and northwest, rushed into the black fog.

The black fog quickly swallowed up the players.

Accompanied by a burst of shouting and killing from the black fog.

In an instant, the screams of players came from it.

Less than three minutes before and after.

The players of the third echelon fled from the black fog one after another.

And it's obviously not proportional to the number of people when they go in.

The people who come out are only about half of those who go in!

Another half, 4 million players, were wiped out by the power in the black fog in just three minutes!!

Look at the third echelon players who are embarrassed to withdraw in front.

The second tier and first tier players stationed at the edge of the city fell into inexplicable panic.

"Shit! The damage is so heavy, why is the enemy so fierce this time?"

"Brothers of the second echelon, get ready to fight!"

Countless players at the four gates reached a consensus.

All players belonging to the second tier attack one after another to replace the players of the third tier to stop the invasion of the ghost army.

However, they underestimated the power of this ghost invasion.

Even the second tier players can't resist their invasion!

The black fog forces the players to retreat back to the main city!

"Ghost forbidden soldiers!"

In the royal family's team chat channel, only a message from a member of the second echelon came, and then the name of the member who sent the message became black in the state of "waiting to die"!

It means that he has been killed by the ghost monster. Wait for other players to pick up the life beads and resurrect within 24 hours!

At this time, Huang Wuji, who was guarding the east gate, looked at the news on the chat interface and frowned: "it seems that Yinuo is right. The strongest forbidden army of the ghost family is coming!"

With that, Huang Wuji immediately ordered: "everyone retreat and prepare to start the defense Tower!"

"Move! Move!"

"Everybody retreat!"

With bursts of shouting.

Countless players in the dark fog retreated one after another.

Because the ghost troops in the black fog are too fierce, even the players of the second echelon of purgatory city can't resist!

Therefore, the second tier players quickly withdrew to the city.

Looking at the oncoming black fog ahead.

Huang Wuji and his men retreated behind the defensive tower.

As the black fog representing the ghost forces in front came closer and closer.

The original ordinary defense tower began to emit bursts of brilliance!

Among them, a defense tower that absorbs the golden element spar and obtains auxiliary power emits a burst of golden light!

WOW!

The golden streamer was startled from the low end of the defense tower to all around.

The next moment, I saw a large area in front of me. A large area of black fog dissipated after being touched by the golden light wave!

Then, countless soldiers dressed in gold armor and fully armed exposed their bodies!

This is true at the four gates of purgatory city.

All the players were stunned when they saw the golden soldiers.

Because in the previous 24 waves of invasion, although the ghost forbidden soldiers also appeared, they were very few.

This time, almost half of the army is the scene of ghost prohibition, which the players have never seen!

No wonder the third echelon and the second echelon just now can't resist the invasion of the ghost clan!

And when the players are shocked.

That group of ghost forbidden soldiers have attacked purgatory city with overwhelming momentum!

At this time, the defense tower did not respond!

"Shit! Isn't this defense tower stuck? The chain falls off at the critical moment!"

"Finish the calf, go and stop them. Don't let these monsters into the city!"

Those players who put all their hopes on the defense tower at the beginning began to rush outside the city to meet the ghost army!

Players collide fiercely with the ghost army and have a strong confrontation!

Players are fighting and retreating, and have gradually approached the city gate.

Because the combat effectiveness of ghost forbidden soldiers is too strong, a forbidden soldier is equivalent to a statistical Lord monster.

At present, there are many forbidden soldiers!

A large group of 180 level Lord monsters, who can stand it?

Soon, the players have retreated to more than a dozen defense towers standing at the gate of the city.

Ahead, the ghost army is sweeping in!

Just when the players fell into despair.

At the gate of the city, there is a defense tower on the left and right sides, which absorbs the red offensive element spar. The top of the tower blasts forward and shoots two red dead lights.

Boom!

The dead light shot down the ground and produced two huge annular shock waves, swallowing thousands of ghost monsters within a radius of at least 300 meters!

In the twinkling of an eye, all the ghost monsters swept by the streamer turned into ashes and dispersed!

Outside the four gates of purgatory City, there is no grass in a large area!

At this moment, all the scattered players looked back at their backs with frightened eyes. Under the guidance of Yinuo Qingcheng, the defense tower was created by the three families.

This is equivalent to the ghost forbidden soldiers of the Lord monster!

I was killed by the defense Tower!!

I have to say that even Huang Wuji, who was observing the enemy's situation at the east gate, was stunned.

He had no idea that the power of the defense tower was so rapid!

Just when everyone was shocked.

Other defense towers have also come into effect.

The defense tower that absorbs spar and obtains healing ability emits green shimmer and covers countless players in the surrounding large area.

Those players who have just been injured have their HP rebounded rapidly.

Even, the corpses of those players on the ground who have been killed in battle and have not yet been resurrected by their teammates through the life ball are directly refreshed and returned to the city after being shrouded in green light!

You don't need others to pick up life beads to resurrect manually!

The defense tower with defense ability will release low light, greatly enhance the injury avoidance of surrounding players, and reduce their damage by ghost monsters by 70%!

The defense tower of the control system calls a multi-layer protective wall outside the large area in front. As long as the ghost monster touches the protective wall, it will be dizzy for 1 second.

And players can freely penetrate the protective wall without any impact!

At this time, the swordsman stationed at the west gate sent a private letter to Huang Wuji: "shit! Have you activated your defense tower? It's really * awesome!"

Huang Wuji looked around. After a round of work, he restored the calm defense towers and replied to the sword Saint: "these defense towers seem to have a long energy storage time. During this period, try to protect the defense towers."

It turned out that the defense tower had not moved just now. It was storing energy!

It is precisely because of long-term energy storage that they can be powerful!

East gate.

After 14 defense towers played a round of effects and brought a wave of heavy damage to the ghost army outside the east gate.

Huang Wuji, who is in charge of guarding the east gate, ordered: "brothers, rush! Wait for a wave of defense tower to store energy, guard the defense tower and defend purgatory city!"
