Ye Fan lurked at the door for a while, finally waiting for the opportunity.

About seven or eight people in white lab coats walked into the research institute.

Leading them was an old man, and Ye Fan recognized him.

This old man was on the Dawn Army's list, surnamed Ouyang, commonly known as Dr. Ouyang.

This old man has done quite a few bad things, whether Level 3 Mutants or armed zombies, he has been involved in all these researches. In Ye Fan's view, his danger exceeds that of a million enemy troops.

A few followers were beside the old man, likely his students.

With so many people, attacking was unrealistic, so Ye Fan quickly found a white lab coat in his pack and hurriedly put it on.

He also took a mask and put it on his face, then followed silently behind them as they passed by.

Guards were stationed at the entrance of the research institute; seeing Dr. Ouyang's group enter, they saluted and let them pass.

Ye Fan kept a straight face and walked into the research institute with them.

When the group reached the elevator, Ye Fan turned to the stairs, his actions natural, without attracting any attention.

Inside the stairway, Ye Fan checked the radar map again, switched the map to 3D mode, and quickly locked on to Hua Wushuang's position.

Fourth floor, in a room at the end.

Ye Fan quickened his pace and soon reached the fourth floor.

There was a guard at the stairway entrance, who immediately reached out to intercept Ye Fan as he approached.

"Which workspace? ID!"

"Oh, I'll show you right away."

Ye Fan reached into his coat and pulled out his gun directly.

Ordinary gunfire would be noticed, but Ye Fan had the freeze ray.

He fired the freeze ray directly, and the two guards were frozen into ice sculptures before they could make a sound.

Before the guards melted or shattered, Ye Fan quickly stored them in his pack and walked swiftly to the end of the corridor.

He encountered a few people on the way, but none of them suspected Ye Fan.

He reached the laboratory door holding Hua Wushuang, and Ye Fan once again opened his pack and released the two engineers inside.

The door was secured with a password lock, and the engineers immediately began deciphering the code.

While waiting, Ye Fan opened the system page and found the Super-Space-Time Transmission Device.

Once he entered the room, Ye Fan would set a transmission point, and after rescuing Hua Wushuang, they could return to the base via this point.

During this process, Ye Fan continuously monitored the surroundings.

The corridor was filled with cameras; this area was under intense surveillance, and Ye Fan reckoned he didn't have much time.

Sure enough, just as the engineers were decrypting the password to its final moments, the alarm suddenly sounded.

The cameras flashed red light aimed at him, and someone remotely shouted at him.

"Who's there? What are you doing? Someone, come quickly! There's an intruder in the fourth-floor laboratory!"

"Alarm! Alarm! The laboratory is under invasion and needs support!"

Seeing he was exposed, Ye Fan couldn't afford hesitation and fired a few shots to destroy the intrusive cameras.

Footsteps sounded from afar; someone was rushing over.

Ye Fan's gun was multifunctional and could also launch grenade rounds; he immediately fired a grenade, which exploded in the middle of the corridor, repelling the pursuers.

At this point, the engineers finally unlocked the password lock, and Ye Fan swiftly entered the room.

Upon entering, several individuals fired at him, but their bullets couldn't penetrate Ye Fan's military gear.

Ye Fan decisively returned fire, unleashing electromagnetic rays.

With a few sweeps of rays, he struck down all the staff inside.

Ye Fan quickly walked to a large container in the center of the room.

Hua Wushuang was placed inside the container, his hands and feet shackled.

The materials looked extraordinary, capable of restraining such a skilled fighter.

Footsteps were approaching from behind, and on the radar map, several figures were swiftly closing in; it was obvious they weren't ordinary people.

Behind Ye Fan, the engineer spoke, "Commander, we must speed up, the enemy will arrive in fifteen seconds."

Ye Fan nodded, first establishing the Super-Space-Time Transmission point, then raised his gun to shoot at the vessel. The bullets hit, yet it remained unaffected.

Ye Fan gritted his teeth and switched to freeze mode directly.

A freeze ray was emitted, instantly frosting the vessel.

He fired again, and with a crash, the vessel shattered, spilling liquid everywhere.

With the vessel's destruction, Hua Wushuang suddenly opened his eyes.

"Ye Fan....…"

"It's me, don't worry, I'm getting you out now!"

Ye Fan tried to open the handcuffs, but Hua Wushuang gently shook her head: "They won't open, do you have any more of that serum?"

Ye Fan paused for a moment, then immediately thought of the commander's serum.

It could save someone even when they're 100% zombified.

After the serum refreshed, it turned into a single vial, and it wouldn't continue to refresh unless used, obviously unable to be mass-produced.

This serum is incredibly precious, even if Ye Fan used it every day, he could only save 365 people a year, which is a mere drop in the ocean for this desperate apocalypse.

But to save Hua Wushuang, Ye Fan didn't hesitate and immediately took out the serum, trying to hand it to Hua Wushuang.

But Hua Wushuang's hands were cuffed; she opened her mouth: "Put it in my mouth."

Ye Fan reached over and placed the small serum inside.

Hua Wushuang closed her mouth and stopped speaking, but Ye Fan could feel that she hadn't swallowed the serum yet, not knowing what her plan was.

At that moment, the enemy broke in.

Meanwhile, a mechanical voice echoed in the room: "Intrusion detected, initiating energy shield."

A faintly wavering yellow light shield began to form, rising from the ground and closing in above, causing Ye Fan to panic.

Not good!

The enemy has also mastered the secret of energy, and he couldn't stay here any longer.

The enemy's progress is swift, and they've mastered the energy body, so he couldn't assume staying in the luggage was safe enough.

Though he wanted to rescue Hua Wushuang, Ye Fan knew he was the top priority.

If anything happened to him, the Dawn Army would cease to exist, and this world would have no future.

So Ye Fan had no choice but to immediately initiate the Super-Space-Time Transmission.

With a hum, a white light door appeared, akin to a dimension door.

Taking advantage of the incomplete closure of the yellow light shield, Ye Fan used the Super-Space-Time Transmission to leave the lab.

After Ye Fan left, the light shield sealed itself.

A minute later, Peilan, Dr. Ouyang, and others rushed in hurriedly.

Seeing Hua Wushuang still there, they breathed a sigh of relief.

"Where's the intruder?"

"After breaking this woman's container, an energy door appeared, and he went inside, disappearing as if he was teleported away."

After listening, Peilan frowned slightly: "A teleportation door... What kind of black technology does Ye Fan hold to create such a thing?"

Dr. Ouyang pondered: "Ye Fan surely has secrets, but we don't know what they are. That's normal; who doesn't have secrets now? Luckily, he was a step slower and didn't rescue this Fourth-level Corpse King, or we'd be in trouble."

Peilan nodded: "Exactly, catch the monk, not the temple; Ye Fan may escape, but his base won't move, as long as Hua Wushuang is still here, we will surely win."

Then he asked Dr. Ouyang: "Is the experiment ready?"

"It's ready. The preliminary tests are completed, and once the final test is done, we can fully control this Fourth-level Corpse King. At that time, Hua Wushuang will definitely reveal her evolution secret, then the second experiment will follow, and we can transform Luo Youyou into a Fourth-level Corpse King as well."

"And are the other Corpse Kings ready?"

"Ready, the backup of one hundred Level 2 Corpse Kings is on standby, once the initial test succeeds, then one hundred Level 3 Corpse Kings will emerge." 𝗳𝚛𝚎𝚎𝘄𝕖𝕓𝕟𝕠𝚟𝚎𝕝.𝗰𝕠𝐦

Peilan sneered: "Excellent, these one hundred Level 3 Corpse Kings are enough to cause upheaval, and with enough accumulated resources, we can continuously create more Fourth-level Corpse Kings. By then, no one will be a threat."

Dr. Ouyang nodded: "Indeed, subsequent plans are also ready. These two Fourth-level Corpse Kings and one hundred Level 3 Corpse Kings will immediately be put into battle to annihilate the Dawn Army first."

"Exactly, the Dawn Army is currently a major threat; once they're dealt with, we'll have plenty of time."

Peilan asked Dr. Ouyang again: "The first experiment must not fail."

"Rest assured, Mr. Peilan, the simulated tests succeeded. According to our analysis of Hua Wushuang's blood and cells, her zombie evolution rate is 90%. Under such conditions, she retains human rationality, thinking independently and opposing us, which makes it challenging. We will fully zombify her first, then implant a chip at that moment to crush her resistance. The rest will be easy."

"Good, very good, and don't forget the security measures. This energy shield can isolate external energies, ensure it's always on to prevent Ye Fan from causing havoc again."

Saying this, Peilan instructed some of the experts behind him.

"Immediately deploy more manpower to protect the entire building and base; thoroughly inspect everyone entering and exiting, not a fly should get through."

"Understood!"

These people went out to arrange things, quickly enhancing the security forces nearly tenfold, leaving no chance for anyone to sneak in again.

Peilan ordered Dr. Ouyang again: "Starting the experiment now to avoid prolonged exposure, pry open Hua Wushuang's mouth to get her to disclose the level-four evolution secret."

"Alright, we'll start now."

Dr. Ouyang organized the team immediately, cleared the site briefly, and began the experiment.

Several tubes were reattached to Hua Wushuang, and specialized viruses began to infiltrate.

As the experiment started, Dr. Ouyang stared unblinkingly at the screen.

99%...100%.....!

Success!

Dr. Ouyang immediately pressed the button for chip implantation!

Implantation was somewhat painful, and Hua Wushuang groaned, her swan-like neck arching high, teeth clenched tightly!
