If the Night Demon really evolved, their physical data would be different from what Robert had collected before.

Reforming the theoretical basis will definitely overturn some of Robert's previous research and waste a lot of time.

But adhering to the rigor of being a scientist, Robert decided to retest the physical data of the Night Demon after returning home to adjust his medication specifications.

Before the sun set, Robert deliberately changed his route when he drove home, and he made a roundabout way before stopping at the doorstep.

Xin Sheng could not feel the surveillance gaze a few blocks away, and the Night Demon obviously hadn't found their base yet.

However, considering the night demon's nature of revenge, it is only a matter of time before he was discovered.

In a last resort, the best way is to give up this base and move to another place to start over.

But it would be a pity to give up like Robert's home with all kinds of defense facilities.

The second choice is to send away the coma female night demon and find a place that cannot shine in the sun. At night, there is a high probability that the Night Demon King is found by the King of Night Demon who is out searching.

However, Robert's experiment was just about to go to a critical moment.

He re-collected the physical data of the female Night Demon, and based on these data, he improved his understanding of the medicine and was observing the effects of the new medicine.

If you hand over the female Night Demon now, don’t consider whether you can gain the understanding of the Night Demon King because of this.

Robert's research can only start over again, and he also needs to take the risk of capturing another night demon to conduct an experiment.

Although he subconsciously refused to admit it, Robert was a scientist after all, and Xin Sheng could think of the possibility that even Xin Sheng could think of.

If the Night Demon is given enough time to continue evolving, the surviving humans will sooner or later have no place to stand and will be completely replaced by the Night Demon with more numerous and stronger physical fitness.

No one knows how long this time will take, maybe hundreds or thousands of years, or months.

Human evolution is a vivid example, and primitive people suddenly have the ability to make tools and communicate with language, which can be said to be without warning.

The sense of urgency made Robert unable to give up the research results that were in front of him and started over again. Now he can only race against time to grab the time.

More than a week has passed since the female Night Demon was captured. Robert's research reached a critical point in the results. He hurried around the laboratory day and night.

Instead, Xin Sheng would drive to the South Street Port at noon every day, while undergoing daily training, while waiting for the survivors to appear.

Change happens to appear in this seemingly ordinary life.

"Um?"

When driving by Robert's usual audio and video store, Xin Sheng, who had outstanding dynamic vision, suddenly realized something was wrong.

The doll model he named "Fred" disappeared.

Due to Xin Sheng and Robert's alertness, the Night Demon King has never found their traces.

But when he went out to hunt at night and searched for his daughter's whereabouts, he accidentally smelled a familiar smell near Robert's long-haunted audio-visual store.

The Night Demon King has a good intelligence, so he soon came up with a way to lead a snake out of the hole.

Sure enough, Xin Sheng soon discovered "Fred" at the end of this street.

It stood in front of a skyscraper, and the towering floors cast large shadows on the ground.

‘A very typical ambush terrain, where the sunlight will be blocked by the surrounding high-rise buildings. When the UV rays are weakened, the Night Demon can launch an attack in advance, and…’

The position of "Fred" standing is located in a puddle, and the part covered by dirty water is likely to have traps.

"Wang!"

Sure enough, when Xin Sheng walked to the puddle, Dahuang first noticed something strange and shouted loudly and issued a warning.

"here?"

Xin Sheng removed the arrow of one of the arrows and carefully pressed along the position reminded by Rhubarb.

"Crack~"

While the crisp sound of punishment from the mechanism sounded, Xin Sheng left and let go of the arrow shaft and retreated.

The suddenly tightened rope mechanism wrapped around the arrow shaft that touched the trigger, and the abandoned car behind Xin Sheng, which was a heavy object, suddenly began to slide down.

"Boom!"

The car that fell under the bridge made a huge noise, and the arrow shaft pulled up into the air was swaying left and right, as if mocking the person who laid the trap.

"Ha~ I copied it, there was no new meaning."

Confirm that there were no other traps nearby, Xin Sheng let Dahuang approach "Fred".

"Remember the smell on the clothes and indicate the direction for me."

"Woo!"

Soon, Dahuang succeeded in finding slut...that is, she tracked down the smell.

Taking advantage of the sunshine, Xin Sheng followed Dahuang tightly, looking for sex with his head down, and gradually came to a three-story building.

"Woom!"

Rhubarb's reaction was particularly intense, and the residual smell on "Fred"'s clothes finally arrived in front of the gate of the small building.

"Three-layer? Humph~ You are unlucky."

Thanks to Robert's home for the vast amount of resources, including gunpowder.

In order to deal with the threat of large-scale enemy cluster attacks, Xin Sheng specially modified several special arrows during this period.

Carefully took out an arrow firmly wrapped in thermally insulated white cloth from the quiver, and Xin Sheng solemnly placed a heavy heavy aluminum arrow on the bowstring.

"Darhuang, follow me to retreat."

Xin Sheng slowly stepped back, his sharp eyes staring at the entrance of the building.

"Continue walking and retreat 100 meters away."

When they returned to about 100 meters away from the three-story building, Xin Sheng and Dahuang finally stopped.

Pulling the bow strings, Xin Sheng did not use a direct shot with greater power and more accurate shooting this time, but raised his bow to pose in a shooting position that could shoot farther.

"Swoosh~"

The arrows left the strings drew a perfect parabola in the air and flew into the windows on the third floor of the small building.

"Look down!"

As soon as Xin Sheng pressed Dahuang to the ground, a violent explosion came from the direction of the building.

"boom!!"

The shock wave detonated from the window shook off all the broken glass remaining on the window at one time, and the glass debris in the sky shot out like bullets from shotguns.

At the same time, a figure suddenly appeared in another window on the third floor of the small building. It was shocked by the explosion and was shocked to the abandoned car nearby. It was in a very embarrassed posture, only more than 40 meters away from Xin Sheng.

"roar!!"

A painful and angry roar erupted from the figure's mouth, and Xin Sheng could see that its skin exposed to ultraviolet rays was burning rapidly.

But the night demon had not given up on his hope of escaping. He endured the pain and tried to turn over and stand up, his slightly dim eyes staring at Xin Sheng.

Xin Sheng, who had climbed up from the ground, squatted his left leg half and kneeled on the ground, and quickly bent his bow and arrow in this abnormal posture.

"Swoosh!"

This time, Xin Sheng did not shoot any further. The high-speed arrow pierced through its neck before the enemy could stand up, disrupting its body balance.

The second arrow that followed mercilessly hit Ye Demon's left chest.

The Night Demon, who was already very painful because of the burning of ultraviolet rays, completely lost his resistance and pounced forward in the sunlight.

"Roar!!"

A roar of sadness and anger came from the sixth floor of a skyscraper in front of the left. Xin Sheng, who had not yet relaxed his vigilance, immediately aimed the next arrow at the place where the sound was made, but he could only see the back of the powerful Night Demon King turning around and leaving.
