The Immortal Bird Project, the laboratory is located in the National Science and Technology Park.

Cloaked in a biomedical shell, he has been secretly conducting biological experiments.

Before Xiao Yu acted, he hid the Heavenly Demon Banner and released forty-nine Yin Spirits, and if an accident happened, the Yin Spirits would be able to rescue him.

If Xiao Yu unfortunately dies, then there will be a disaster in the future Dust Feather Star Country.

The Heavenly Demon Banner becomes an ownerless thing, and over time, the magic circle in the magic weapon will become invalid, and the forty-nine Yin Spirits will be free, so that they can unscrupulously devour qi and blood to grow, and evolve into a ghost cultivator-like existence.

"Calculate the time, Geodin should initiate the operation."

Of course, Xiao Yu didn't believe the other party, and deliberately delayed for a quarter of an hour before making a move.

The time chosen was at night, and Xiao Yu's eyes locked on a patrol soldier, who was equipped with power armor and was not as strong as a mecha.

"Who!"

The soldier noticed the movement and was about to look for his target, when suddenly a black shadow swept by, slapping his palm on the armor of the head.

The palm thunder seeped out the concussive power, causing the soldier to faint instantly.

Disarming the power armor, Xiao Yu equipped it himself, and threw the soldier into the sewer.

Pretending to be on normal patrol, when approaching the door of the laboratory building, Xiao Yu swaggered in.

"Why don't you go on patrol?" The soldier stationed in the hall stepped forward and asked.

"Go to the toilet and smoke a cigarette." Xiao Yu found a reason at random.

"Hurry up, it's time to change shifts."

The soldiers stationed there did not deliberately embarrass and let Xiao Yu into the building.

I found a random storage room and disarmed, and found that there were a lot of maintenance workers' clothes, so I changed into a set.

When passing by a toilet, I met two researchers who were swallowing clouds and spitting fog.

"Fortunately, I transferred my wife and children away and obtained funds from the organization, and they have no worries about food and clothing for the rest of their lives."

"I'm just alone, and I thoroughly enjoyed it before and became an uncle."

"I really can't figure it out, you are young and with your academic qualifications, it is not difficult to find a decent job outside."

"It's not because of a woman, who is on the list, wants to kill me, so she simply took refuge in the organization and killed them first, a pair of dog men and women."

At this time, as soon as Xiao Yu walked in, he reached out with one hand, crushed the vertebrae of a person's neck, and grabbed a person's throat with the other hand to prevent him from making a sound.

"If you don't want to die, cooperate." Xiao Yu said indifferently.

"Okay, I'll cooperate." The young scientist responded.

Put on a white coat and hold the researchers hostage and walk towards the laboratory.

The laboratory is on the second basement floor, and the ground building is an empty shell, which is only used as a cover.

Taking the elevator, the scientific researcher could not see anything unusual on the surface, cold sweat was oozing from his forehead, and he saw that his colleague was as easy as strangling an ant, and if he showed resistance, he would definitely solve it.

Divided into many experimental areas, the isolation tubes contained different subjects, both animals and humans, and they were still alive, relying on hoses to deliver oxygen and nutrients to sustain their lives.

"These are all failed test subjects, and they are very flawed." The researchers explained.

"I don't want to know, take me to the source." Xiao Yu said calmly.

The source body is the source substance of the experiment, as long as it is determined that it is a treasure of heaven and earth, Xiao Yu will take it away, otherwise blow up the laboratory.

Arriving at a laboratory that requires identity verification, researchers use their identities to pass.

For a while, what appeared in front of Xiao Yu's eyes was a vat of immortal stock liquid, and many scientific researchers were busy coming and going, and a new round of experiments was underway.

"Garro, who is he?"

Someone looked at him suspiciously, and the researcher didn't know how to explain it.

Simply, Xiao Yu no longer concealed it, slapped the hostage to death with one palm, and then killed the speaker with one punch.

"Hand over the ore."

Xiao Yu's eyes swept over the stunned crowd, trying to find out the person in charge of the project.

Unfortunately, it backfired, and the next moment the alarm sounded, and someone touched the alarm device.

"You were the one who triggered the alarm."

Xiao Yu found out a middle-aged woman, she was deep in the workbench, and she couldn't be wrong.

"There are heavy guards here, and there may be a way to survive if you are captured." The middle-aged woman said calmly.

Boom!

Xiao Yu picked it up and smashed it into the glass jar containing the immortal essence, and the whole piece shattered, the immortal essence gushed out, and the aura permeated the entire laboratory.

After killing three people in a row, someone was finally afraid of Xiao Yu's obscenity and handed over a fist-sized blue crystal.

Holding it in the palm of his hand, the rich aura is transmitted out, and the true qi in the body is boiling.

"Spirit Stone!"

A thought popped up, Xiao Yu was not sure, he had never seen a spirit stone, how could he be sure what it was.

But the aura contained is a treasure of heaven and earth, there is no doubt about it, and it belongs to the category of absorbable refining.

The Heavenly Material and Earth Treasure of refining magic weapons has special attributes, which are in line with the strength of the relevant magic circles and are compatible with increasing the lethality of magic weapons.

Just as he was about to turn to leave, the genetic warriors arrived.

"Kill on the spot."

Seeing the target's face clearly, he shot with all his might, not daring to have any reservations.

The energy beam shot in, Xiao Yu cast his pupil, dodged the attack, approached in an instant, and blasted a punch into the deadly part.

With one blow, the two genetic warriors were hit in the throat, and the external armor was dented, covering their throats and struggling, and then they stopped moving.

Observing the death of his companion, the rest of the genetic warriors discovered that Xiao Yu had disappeared.

"Target is heading to the surface, blocking the elevator."

At this moment, at the elevator door on the first floor, more than 20 genetic warriors are waiting for the rabbit.

Looking at the lights jumping, the elevator is rising.

When he reached the first floor, before the door opened, the dense energy rays pierced through the steel plate and directly formed a honeycomb.

Bite!

As soon as the elevator door opened, the elevator was empty, and Xiao Yu was not among them.

"Blockade the entire building, and monitor the synchronous transmission of the system."

The synchronous video of the monitoring probe was transmitted to every soldier and genetic warrior, and Xiao Yu was soon locked on the second floor.

Outside the building, the soldiers are armed with heavy tracking weapons, as long as Xiao Yu dares to show up, the high-explosive magnetic missile can directly bombard and kill into coke.

As soon as I tried to get out of the second-floor window, a missile was fired.

With a bang, a three-meter-diameter hole blasted out of the wall, and the high temperature of the thunder slurry at the edge caused the reinforced concrete to melt into magma.

"If you force yourself to die, you will use a thunder slurry warhead." Xiao Yu was shocked.

He didn't wear a mecha, he would become charcoal if he resisted one, and there was not even any scum left, and now he couldn't help but miss the magic mecha, which was not discarded at the time, and was used to resist one or two missiles, maybe he could seize the opportunity to get out.

"Find the target, locate the third workspace."

The genetic warriors chased and killed, and as soon as they met, the energy cannon bombarded indiscriminately, giving the opponent no time to react.

Constantly wandering around the building, Xiao Yu is more like a hunter, wandering and then hunting enemies.

In a quarter of an hour, more than ten genetic warriors had died.
