On the other hand, human beings here have been under the threat of gray liquid monsters and faced with the sinister situation of extinction at any time, which has forced their scientific and technological level to soar, otherwise they may not be able to support it long ago.

……
"It seems that there is no shortage of resources, and the gray monster will no longer appear stronger. The human defense line here can be limited to support." Yu Guihai pondered.
Suddenly, his spirit shook and he looked intently and saw that there was an abnormality on the defense line.
It was the three-way cloud nine gray monster that moved at the same time. They gave a strange howl and besieged the defense line. The Kusu monster immediately hit the chicken blood and suddenly became violent. The offensive immediately multiplied.
The planetary defense circle is not flustered. Obviously, it has experienced this situation.
The main fulcrum fortress world light flash immediately emerge more muzzle.
Many virtual fortresses have also emerged with more encrypted small guns, and countless warships have flown out of support lines from all over the world like bees.
The crazy attack of Kusu monster didn’t produce much success, and the planetary defense circle was as strong as ever.
At this time, the three-way cloud nine gray monster moved again and moved towards the defense circle at the same time.
At this time, nine of the world’s giant cannons quickly turned the muzzle three, and one aimed at the three gray liquid monsters and slowly charged.
In dozens of other doors, one-third of the guns bombarded the monster who attacked Kusu crazily, while the rest deterred other monsters who had not yet acted.
At the same time, the defensive circle, which was transformed into a virtual world base, and the strong breath of human beings in the big world also increased.
The two strongest forces in the human world are ready to meet the attack of the gray liquid monster at any time.
Gollum ~ ~ ~
The gray monster sound can be clearly played even if it is really empty.
It’s like a signal that the three-ash monster accelerates towards the defense circle at the same time, and the body emits terrorist fluctuations
The black spikes of the gray monster suddenly shot out, and the tentacles of terror were full of strange eyes.
They are going to launch a powerful attack on the defense line. If the three-ash monster succeeds, the defense line will be damaged.
Boom ~ ~ ~
A violent roar sounded nine ju pao, and at the same time, terror was more intense than hot white light maser.
The interweaving of light beams directly dispels several Kusu monsters, and then locks two of them every four doors, blocking their escape angles.
These two gray monsters tried to dodge, but they were still hit by two beams of light, and they were evaporated in an instant. Most of their bodies and a small part of them were instantly broken into messy gray mucus.
Those nine giant cannons have made a small trick. Their goal is never to target three monsters, but to ensure the destruction effect against two monsters
This stratagem was really successful. The two gray liquid monsters were caught off guard and were directly hit hard and dying.
It’s better to break one finger than to hurt its ten fingers!
Yu Guihai couldn’t help but be amazed.
He carefully watched the remaining gray monster. What should he do?
At this time, I saw an elder, a beard and a blue robe flying out of the base world. Middle-aged middle-aged looks elegant and his forehead has a sharp murderous look.
Middle-aged people hold a simple round mirror in their hands. This round mirror has some broken parts and a small piece of sample is missing. It looks very inconspicuous and does not feel fluctuations.
But Yu Guihai’s face showed a dignified color.
Because of this, the round mirror is not simple, and what’s more, he actually feels a little bit of danger from this round mirror, which is weak but fatal.
Can threaten his life enough to predict that this round mirror is powerful.
……
Suddenly, the gray liquid monster that escaped through the net dashed towards the middle-aged man, counting his eyes and shooting gray beams at the same time. Together, the gray beams formed a thick and horrible beam and shot away towards the middle-aged man.
The middle-aged man suddenly raised his hand and a sword of light flew out of his body. Linghua was greeted by a giant sword thicker than that beam.
Sniff ~ ~ ~
As soon as the two contact, the gray light beam is cut into two halves and maser towards both sides.
"Not good!"
Middle-aged eyes shrank, and these two halves of gray note suddenly took the opportunity to bypass him and bombard him with the defensive circle behind him.
