Ultra-high-speed cameras, infrared rays, these are the most basic places, and there are even high-grade goods for monitoring the changes of the earth’s gravity field and magnetic field.

These instruments generally operate by satellite.
But when the observation was made, the tunnel was sent over whether it was there or not.
Zhou Jianhai and all kinds of science leaders gathered in front of the observation window, nervous and sweaty.
Zhang Tianyuan opened the main control panel of the base while watching in the car.
Choose the world "I am strange"
Determine the destination of the imperial city
"Open the time door!"
One second
When it was dark, the tunnel suddenly appeared, and everything in the square was swallowed up and disappeared according to Zhang Tianyuan’s wishes.
Then there was a nervous and excited sound outside the square.
"They really disappeared!"
"Did they really cross into parallel time?"
"Hurry up and open the video just played back. I want to see how it is realized …"
Zhang Tianyuan, the noise of the shelter, has been heard by them.
Because they have come to another world.
……
In the dark and shabby city, the streets are full of trees and green leaves, and a pair of bare feet trample on the ground to rot and accumulate fallen leaves, looking at the moon in the sky and howling
All the birds around the trees were awakened and flew away from the trees with a strange cry.
One second, a pair of big gray hands stretched out from the darkness and reached for its nest …
Trees wander the streets in droves overnight.
They either rush into the house to search for everything they can eat with their noses or rush into all kinds of corners where animals live to drive them out.
Cats, dogs, mice and even some giraffes, cattle and sheep …
After humans receded, the steel forest became an amusement park for animals and a hunting ground for night demons.
This is a daily hunting operation.
However, tonight is a little different.
Nightmares sprinted after their prey, and a black shadow flashed across the road, and then bang, as if something crashed to the ground, and the air was squeezed out.
Knock!
The original was far ahead and rushed to the front, which was the most likely to capture the prey. The nightmare directly hit an iron wall, and before it could react, a huge recoil made it faint.
At the same time, a driver felt that his armored truck seemed to sway.
Zhang Tianyuan looked out of the bulletproof window and knew he was late when he saw that the city was dark and there was no artificial light.
"Ladies and gentlemen, we’re late. The doomsday event has happened, and according to the present situation, human beings have fallen …"
This is the capital!
It’s all dark here, even if the timeline is not at the beginning of the plot, it’s definitely been a long time since the virus spread in 212 years.
Thought of here Zhang Tianyuan hurriedly grabbed the phone again.
"Everyone don’t open the car window and take your weapons and hand barrels and wait for the test results of the nuclear and biochemical team!"
When a series of white came back, Zhang Tianyuan suddenly heard a shrill howl coming from the outside.
He reacted immediately.
"It’s a nightmare!"
As early as Zhang Tianyuan, when they just appeared, the night demons had already reacted.
After being transformed by viruses, their bodies are extremely adapted to the dark environment, especially their eyes can see clearly even in the dark.
They can see the people sitting in the car at a glance.
They know that this kind of similar species is their food.
But this kind of food has not been seen for a long time …
And now it’s suddenly here again, which means-
It’s moving!
The street nightmare group sprints wildly, turns into dead gray skin and face after pigment precipitation, and the symptoms of depilation after virus infection make them look like a group of bald heads who can sprint and marinate eggs.
vehicle
Zhang Tianyuan looked at the sprint and came to Nightmare.
There are so many nightmare. When they act together, they actually pile up into a human wall. Many nightmare directly step on their companions’ shoulders and jump towards them quickly.
And in more than one direction, there are a lot of nightmare behind them to report.
Even the buildings on both sides of the street jumped out of a lot of nightmare, and directly dropped the probe on the roof to bang the window …
"What now?"
Bai Xu nervously looked at the bare face outside the window.
