Suddenly it seems that something has changed.

Tangible and mysterious forces bloom from the heart of the oasis and spread throughout the oasis in an instant. This kind of force can only be perceived by the mentor who is in charge of the heart of the oasis, but the Spark Oasis is also undergoing significant changes in the eyes of others.
-More than a thousand meters away, the oasis boundary is moving outward at a slow but firm speed.
The thick gray fog covering the earth is fading inch by inch, exposing the land that is still barren, but you can still see the sparse grass seedlings, which is not as dead as the real land.
The defenders of the city wall watched and gradually held their breath.
The oasis is expanding faster and faster, but at the same time, the fog that is being squeezed by the oasis and retreating is gradually changing from a relatively calm state to a violent and manic state, like a high wall, and the fog changes in the blink of an eye, and the waves seem to be brewing a terrible storm.
This scene is no stranger to the veterans stationed in the Spark Oasis, but they still see at a glance that this time the fog surge is far more intense than the previous ones-it looks like the fog surge, but they feel a burst of depression.
"Yes, coming!"
The old soldiers stopped laughing and became dignified.
Meng Xin clenched their weapons and stared at the distance unblinkingly.
At the moment, the distance between the city wall and the edge of the oasis has been extended by five or six kilometers. In this barren area, the sunlight is visible, and the vision is far superior. Even in the eyes of the elite defenders, they can see clearly the grass swaying slightly with the breeze in the distance.
But they can see the scene in the fog, and the line of sight can reach hundreds of meters at most … This is also the difficulty of oasis guarding city. Everything in the fog is invisible to the defenders, and it can only be observed when they reach out of the fog.
Or perhaps the myth bears the burden of scouts, and the myth frequently looks through the fog.
Spark oasis doesn’t need it
Oasis headquarters black knife stands in the middle. In front of him, there are more than a dozen unskilled operators manipulating clumsy instruments. Finally, these instructions converge with a crystal display screen to present a scene outside the oasis.
The fog filled the earth with tremors.
What is more amazing is that the fog in the picture is very strong, and the field personnel can still see the scene in the fog clearly, and they can also adjust the visual angle of the picture or overlook it or close up it or change the direction.
This is a picture from the detection eye.
In the early preparation stage, Black Knife chose dozens of locations outside the oasis to build a’ detection eye’. Now, with this epic, he can get information outside the oasis without early warning and detection, and he has more tactics.
….. Actually, his most application for building detection eyes was 610. Unfortunately, the instructor rejected his application and finally built ten.
Thought of here, Black Knife’s eyes stared at the detection pictures more sharply, predicting that the siege wave was heading for him to give these paradoxes a head-on blow.
……
Fang you also looked at these detection images.
He didn’t take advantage of the black knife vision panel, and there is a hard connection between these buildings built by miracle drawings, just like incorporating oasis into the base module, he needs to make external equipment directly see the detection eye picture.
However, his observation focus is different from that of Black Knife.
Since ……bushi appointed the commander-in-chief of the Black Knife garrison, he wouldn’t intervene in the observation of the tour, focusing on these mysterious evils. If they appear, he still can’t see clearly that the siege mysterious evils don’t come from the surrounding areas.
Some evil spirits perceive fluctuations or temptations flock to the oasis. However, it seems that more evil spirits attack the city by popping them out through a heavy fog curtain and stepping outside the oasis, and they are smashed into the rushing wave of evil spirits and charge together with their peers.
"The evil is coming!"
The eastern defense line is the first to issue an early warning.
After the generals put their officers on guard, the fog surged to a certain threshold for dozens of seconds, and one ferocious evil spirit rushed out of it.
These cunning evils are no more than one meter high, ugly in appearance, but not terrible. A star of cunning evil knockers is the representative everywhere, but there are many ferocious cunning evils with huge size and hundreds of meters high. They stomp on the trembling earth and kill one or several knockers. They are full of teeth, and they rush to the ground with their mouths, feet and arms.
There is not much preheating. This oasis promotion war is more fierce than the defense of Shui Ze base city.
Terrible six-star natural disaster level cunning evil into the eye.
Have you seen such a scene when Meng Xin was born? The whole blue star can’t find the natural disaster level evil spirit now, and they have been killed into a rare symbol.
"Hold your horses and implement the predetermined plan, but it’s just a six-star evil!"
The old birds are steady.
The roaring of giant guns and the shooting of arrows and rain have gradually stabilized their mentality and made them feel cool! Watching the mysterious gunfire disappear, a pit and a large area, they feel more relaxed than playing grass-cutting games.
However, after all, it is the strongest wave in the history of 6 Jin and 7 Jin. This tour has specially recalled the mythological black knife brothers from all over the world and is going to install hundreds of reconnaissance eyes … If the siege wave is large, aren’t they prepared for nothing?
They didn’t prepare for nothing.
Before the first wave of siege in the eastern defense line wiped out all the defense lines in the southeast, west and north, they met the rushing black waves one after another. There were too many black waves, and there was not enough gunfire roar to stop the footsteps of these evil waves. They gradually approached and then met the defenders who had already been unable to hold back.
Boom!
