In the world after the disaster, the human industrial system completely collapsed, and the existing ammunition is very precious resource, use a little less.

Before he had no choice, Xin Sheng did not want to use a killer such as explosives. The traps arranged according to the on-site environment became the best defense to block the attack of the Night Demon.

The first batch of more than a dozen night demons were knocked down by two of them before they could figure out the situation. Even if they didn't die, they wouldn't be able to recover their combat effectiveness in a short period of time.

"roar!!"

The angry roar of the Night Demon King resounded throughout the night sky, and the second batch of more than fifty Night Demons followed and began to charge.

This time they advanced a few more steps, and when they walked only ten meters away from the Arc de Triomphe, they triggered a fatal trap named the blade array by Xin Sheng.

While the agency was launching the machine, the kitchen knives collected from various households were shot out due to the pulling of the Night Demon and triggering the steel wire.

"Well!"

"oh……"

The bright knife reflected a cold light under the glimmer of light from the starry sky. Most of the night demons who stepped into the formation were stabbed into hedgehogs by kitchen knives. The injuries of three swords and six holes on their bodies looked extremely scary.

Although the Night Demon has evolved a considerable wisdom, it is still incomparable to humans at this stage.

This fatal threat that even the enemy cannot see made many night demons fear, and it was entirely restricted by the roar of the Night Demon King to prevent their morale from collapsing on the spot.

After being blocked by incomprehensible things one after another, the Night Demon King gradually lost his patience.

"Ao!"

Amid the third order roar of the Night Demon King, nearly half of the total night Demon sinks down his body's center of gravity and is ready to sprint.

Xin Sheng kept a half-squat bow-pull and calmly said to Robert through the intercom: "It's coming, the first round of total attacks."

“Open the UV headlights on the front of the mansion.”

The night demon army, howling and charging, rushed forward, and after nearly a hundred sacrifices, it finally broke through the dense trap array and crossed the door hole of the Arc de Triomphe.

The Night Demon King showed a winning smile on his face, but its happiness didn't last long.

"Ba~ba~ba~ba~ba~"

Five high-power ultraviolet lights on the front of the base are turned on at the same time, and the bright lights of lilac illuminate the lights near the Arc de Triomphe.

The dozen night demons who rushed in front were directly exposed to ultraviolet rays.

"Ahhhhhh!"

Ultraviolet rays are the natural enemies of the Night Demon. The unlucky guys who rushed the fastest immediately covered their faces and fell to the ground and rolled around in pain. There were obvious charred marks on their bodies.

The Night Demon compatriots who followed behind immediately lost their previous impulse and hid in the shadows of nearby cars and buildings.

UV rays are like wild beasts seeing fire to night demons, and the effect is more significant. They will instinctively avoid areas exposed to ultraviolet rays.

The Night Demon who tried to walk around from the side also had no good results.

Before turning on the UV headlight, Robert had turned on all generators in the house, and sufficient power could maintain the exposure of the UV lamp for a long time.

The entire base was completely surrounded by ultraviolet headlights, just like a porcupine that exploded, making the cluster charge Night Demon unable to start.

"roar!"

The Night Demon King's brain seemed to evolve more advanced than others. It was the first to pick up the stone on the ground and signal its subordinates to pay attention to its movements.

"Bang!"

Under the powerful force of the Night Demon King, the stone hit the solid exterior wall of the mansion heavily, without any effect.

But all the Night Demons were inspired by the leader's actions, and they hid in the dark one by one and began to bend down to collect thrown objects.

Xin Sheng on the roof noticed this scene and frowned and told Robert about the current situation.

"It's true as you said."

Robert rubbed his temples with a bitter face: "The Night Demon has evolved a clear sense of community, and their brains have begun to have the ability to think."

After sending Ethan into the underground laboratory, Anna held her rifle tightly and returned to the ground.

Although the traps and defenses prepared by Robert and Xin Sheng made her very amazed, the way Night Demon dealt with them made Anna even more uneasy.

"Robert, what should I do next?"

"Once the UV light is knocked out, we will be directly exposed to the Night Demon's attack."

“It’s not that easy.”

Xin Sheng heard Anna's words through the radio intercom: "We have not used up our backhand yet, just watch patiently, it's not time to end our end."

"Bang!"

The three ultraviolet lights on the left side of the mansion were all destroyed by the flying props thrown by the Night Demon vigorously. Dozens of Night Demons who were ambushing on the left immediately rushed over.

"Detonate the remote-controlled bomb on the left wing."

After receiving Xin Sheng's prompt, Robert, who was ready, looked ruthless and pressed the remote control button in his hand heavily.

"Boom!!"

The car with bombs exploded in the group of Night Demons, and the Night Demon who rushed to the left was almost completely destroyed. The Night Demon who was moving in this direction was also greatly impacted.

"Swoosh!"

After avoiding the aftermath of the explosion, Xin Sheng finally shot the first arrow.

A night demon, who was dizzy by the power of the explosion, was shot through the neck by an arrow, and fell down in a daze before he woke up from the dizziness.

Xin Sheng had already prepared for this decisive battle that would come sooner or later. The three-finger gloves and deerskin rings that protected his fingers allowed him to pull the bowstring continuously without being cut by the string.

Within 50 meters, Xin Sheng's arrows were like accurate sniper bullets, and there was no fire in one shot. The Night Demon, who was shocked by the aftermath of the explosion, was shot one by one under Xin Sheng's rapid shooting.

At the same time, Robert also opened the observation hole on the main door and worked with Anna to probe the barrel of the m4 assault rifle.

"Da da da da da da!"

The already very lively night added a series of gunfire. The Night Demon, who was hiding outside the ultraviolet lights, was hit by the bullets of the m4 rifle and fell in pieces like harvesting wheat.

In order to regain his daughter and take revenge on the bold alien race, the Night Demon King called on all his subordinates whom he could control, with about 500 people.

Under the repeated attacks of traps set up by humans, more than 500 Night Demons have died nearly half and countless injured people.

Only more than 100 people from the right clan of the Night Demon King remained in a state of unscathing.

Although the losses were unacceptable, the Night Demon King did not give up because of this.

Robert and Xin Sheng have collected all the ammunition they can find in recent times, but with the rate of fire of the assault rifle, the bullets were quickly shot out.

Robert and Anna have switched out pistols as sub-weapons and killed the Night Demon who is trying to get close to the mansion with a point shot.

Xin Sheng on the roof had already stood up and blatantly shot the enemy one by one in an orthodox posture.

There are three remote-controlled bombs split by Xin Sheng, and the bomb on the left has been detonated.

While the bomb was hitting the Night Demon, Xin Sheng cleared all the Night Demons near the left side of the mansion.

"roar!!"

With this roar that resounded through the sky, the Night Demon King finally couldn't wait any longer and personally led his direct subordinates to launch a charge.

"Robert!"

Robert's face turned red when he noticed this scene and he pressed the detonation button in his hand fiercely.

"Ding~"

"Boom! Boom!!"

The bombs on the right and middle lane that were detonated almost at the same time bombed the remaining large number of Night Demons into the sky, and the broken limbs and arms were flying around. The Night Demon's blood even dyed the entire asphalt street blood red.

Regardless of whether this battle will be won tonight, at least Robert's mansion can no longer live in.
