Wingsuit is a device that simulates the principle of bat flight and uses the acceleration of high-altitude dive to carry out unpowered flight.

The wingsuit's arms and feet are attached to the wing membranes, which is also the key to the wingsuit's unpowered flight.

Wingsuit flying, also known as close-range sky gliding, is a kind of extreme sport, which is very dangerous, so its popularity is very low.

Originally, wingsuit flying only existed as a non-powered flight sport, but gradually, with the in-depth research of special operations by the special forces of various countries, it also has a place in the field of special operations.

Special forces can use wingsuits to fly down at high altitudes to carry out surprise attacks on target bases and carry out combat operations.

The rain soon blurred the windproof glasses in front of Ye Xiao's eyes, and the rushing rain kept pouring into his mouth and nose, and in order to maintain his flying attitude, Ye Xiao couldn't care about the rain splashed on his face.

Wingsuit flying is already a very dangerous sport, and flying in a wingsuit at night under such a rainstorm is undoubtedly more dangerous again.

If it weren't for the flashing red anti-collision lights on the roof of the G. Biological Research Company building as a guide, Ye Xiao wouldn't even be able to distinguish the landing point.

When his body fell to the roof of the G. Biological Research Company building, Ye Xiao opened the deceleration parachute bag behind him, and the open deceleration parachute instantly reduced Ye Xiao's gliding speed, so that Ye Xiao landed on the roof of the G. Biological Research Company building quite smoothly.

Soon after Ye Xiao landed, Chen Han and Wu Weilie also landed one after another.

The three of them quickly put away the parachute, took off their wingsuits, took out the short-barreled SCAR-H automatic rifle from the tactical backpack, and then split the special tactical backpack into two halves, and after fastening them together with the tactical buckle, it became a tactical vest on the body.

Ye Xiao took a glow stick from the tactical vest and put it on the roof of the building, then took out a fixed base of a rope gun and installed it on the roof of the building.

In the office building, Kan saw Ye Xiao's glow stick, immediately got up and took out a rope gun from a travel bag, aimed at the location of the glow stick on the roof of the G. Biological Research Company building, and pulled the trigger.

Boom!

An electromagnet was installed, and the head of the wire lance with a cross thread on all sides flew to the roof of the building of the G. Biological Research Company with a rope.

Ye Xiao grabbed the head of the rope gun that fell on the roof of the building and installed it in the pedestal fixed on the roof, after the electromagnet of the head of the rope gun sucked the electromagnet in the base, he used the cross threads around the head of the gun to completely fix the head of the rope gun and straighten the rope.

In the office building, Kan also fastened the ropes, then attached locks to the other three travel bags, buckled the ropes, and slid the three travel bags to the roof of the G. Bioresearch building through a rope erected between the office building and the G. Bioresearch building.

Ye Xiao caught the three travel bags that slid to the roof of the building, one of which contained a set of drilling machines, while the other two travel bags were filled with C4 plastic explosives.

Through the information provided by Li Shanjia, Ye Xiao had basically determined the location of the mutant virus laboratory, and Chen Han picked up the drilling machine and drilled at the location pointed out by Ye Xiao.

The drill bit penetrates deep into the roof of the reinforced concrete structure, drilling several round holes with a diameter of 5 centimeters and a depth of 15 centimeters.

Ye Xiao and Wu Weilie took out C4 plastic explosives from the other two travel bags, filled them into the round holes, and stuffed the wires of the remote control fuse into the plastic explosives.

Ye Xiao, Chen Han, and Wu Weilie installed the rope descent bracket on the roof of the building, and after the rope descent bracket was connected to the carabiner on his waist, Ye Xiao nodded at Chen Han, and Chen Han pressed the remote control detonator in his hand.

Boom! Boom! Boom! Boom!

A few faint flashes of firelight, a round hole was blown out of the roof, Ye Xiao kicked the travel bag containing C4 plastic explosives down from the mutant virus laboratory, and then grabbed the rope and lowered into the mutant virus laboratory.

The explosion blew off the fluorescent lamps on the ceiling of the laboratory, and the lights flickered on and off, making a faint "stabbing" sound.

Ye Xiao, Chen Han, and Wu Weilie, who had slipped into the test, couldn't help but be angry when they saw the test subjects in the glass observation room of the laboratory.

The variant test room on the fifteenth floor was used for the variant smallpox test, and the enclosed glass observation room housed the test personnel who had been forced to undergo the test of the variant smallpox virus, who were strapped to the test bed and injected with the variant smallpox virus.

After being infected with smallpox virus, there will be severe symptoms of blood poisoning, and the skin will appear macules, papules, herpes, and pustules, and the fatality rate is as high as 30% 15~20 days after infection in unimmunized people!

This is still the ordinary smallpox virus, and the variant of the smallpox virus, which has been re-studied by G. Bioresearch, will have more severe infection symptoms and a higher fatality rate.

On top of that, existing smallpox vaccines have no effect on variants of smallpox at all, and can still be fatal if infected with the variant of smallpox. And the variant smallpox virus has a lethal rate of up to 80 percent!

In other words, if there is no antiviral, as long as you are infected with the variant smallpox virus, it is basically a dead end.

The subjects confined to the glass observation room ranged in age, from the oldest to the youngest in their sixties, with an equal ratio of men and women. They had no strands on their bodies, and their bodies were covered with herpes, pustules, some of which had ruptured, and disgusting fluid stained the test bed.

Some of the test personnel have died, while others have not.

After seeing Ye Xiao, Chen Han, and Wu Weilie, these non-dead experimenters regained their brilliance in their originally gloomy eyes, and they tried to struggle, trying to ask Ye Xiao, Chen Han, and Wu Weilie for help.

Ye Xiao, Chen Han, and Wu Weilie didn't pay attention to their pleas for help at all, because if they were not careful, they would also be infected with the variant smallpox virus.

"Demon hunter to find antivirals!" Ye Xiao said to Wu Weilie: "There must be antivirals here!" ”

"Immortal bird, I'll go with you to find someone."

Ye Xiao and Chen Han quickly walked in front of those glass observation rooms, looking for Li Shanjia's sister.

Before leaving, Ye Xiao, Chen Han, and Wu Weilie had already seen the photos of Li Shanjia's sister, and if his sister was really here, it would not be difficult to find her.

"Look here!"

Suddenly, Chen Han stopped Ye Xiao and motioned for Ye Xiao to go to his side.
