He led the Variant and the Companion Beast out of the isolation room. After closing the door, he went next door to retrieve the sapling. Only then did he bring the Variant and the Companion Beast to Professor Yan's monitoring room.
Through the screen in the monitoring room, Zuo Feng closely watched the Slash Zombies in the isolation room. After the suppression from the Variant and the Companion Beast disappeared, they began to look around anxiously, trying to break free from the chains. However, the a-level metal chains were extremely sturdy, and they were unable to break free.
Zuo Feng secretly rejoiced, the A-grade metal chains were indeed reliable; even Six-Slash Zombies couldn't break free. However, the Slash Zombies did not give up. They let out even more violent roars, their muscles tensed, and the blood-red patterns on their crimson skin became increasingly striking, as if about to ignite. Clearly, they were gathering strength, preparing for a final struggle.
Zuo Feng held his breath, his eyes fixed on the screen, ready to deal with any sudden situation.
Time slowly passed, and the roars of the Slash Zombies gradually weakened. Finally, they lowered their heads weakly, seemingly having exhausted their last bit of strength. The blood-red patterns on their skin also gradually dimmed, returning to normal.
Zuo Feng let out a long breath. It was impossible for the zombies' stamina to run out so quickly. These Slash Zombies had actually learned strategic abandonment, temporarily suppressing their ferocity, and waiting for the next opportunity.
Zuo Feng's heart was alert; the cunning of the Slash Zombies far exceeded expectations.
Zuo Feng frowned deeply, his fingertips unconsciously tapping the cold control panel, producing dull thudding sounds. The intelligence level displayed by the Slash Zombies had far exceeded the scope of ordinary zombies acting purely on instinct. Strategic abandonment? This meant they could not only assess risks but even began to possess rudimentary tactical thinking. This was more terrifying than a mere evolution of physical strength.
On the screen, the two Six-Slash Zombies were like two solidified blood-red statues, with only extremely slight undulations in their chests, indicating they were not truly quiet. Beneath their lowered heads, their crimson eyes occasionally rotated very slowly, scanning every corner of the isolation chamber, as if searching for a weak point in the chains, or perhaps calculating something. Zuo Feng could clearly feel that their gaze would always linger for a moment when it swept over the isolation room door, as if evaluating the possibility of escape.
This calmness and scrutiny sent a chill through Zuo Feng's heart. These zombies were truly terrifying, especially their numbers; who knew how many pathogens were still in H City.
Zuo Feng had already confirmed that H City was doomed.
At this moment, Da Bai Tu's voice came from the walkie-talkie next to Professor Yan:
"Professor Yan, how are things inside?"
"Temporarily stable, but the Slash Zombies are exhibiting astonishing intelligence. The situation is not optimistic," Professor Yan responded in a deep voice, his brow furrowed.
There was a moment of silence on the other end of the walkie-talkie, then Da Bai Tu's voice sounded again: "Ask Xiao Nan Ren if we can return to the base now." It turned out that after Kong Ling left, Da Bai Tu always felt something was off, and her heart was uneasy.
So, she had brought Firefly's girls back to the base early today, and on the way, she coincidentally met Da Mi Tao and her group. After talking, she learned about what had happened at the base.
Zuo Feng took the walkie-talkie: "Da Bai Tu, there's nothing wrong for now, come back. Da Mi Tao is also with you, right? Tell her to come back too, and bring those researchers with her."
Da Bai Tu's first question was whether Professor Yan was alright, which made Zuo Feng certain that Da Bai Tu and Da Mi Tao were together; otherwise, she wouldn't have known what had happened at the base.
Da Bai Tu's voice came through the walkie-talkie, carrying a hint of undetectable tension: "Received, we'll be there immediately." She paused, then added, "Xiao Nan Ren, you be careful too."
Zuo Feng was not worried about Firefly's girls having the New type of symbiotic zombie virus in their bodies, because he and Da and Xiao Mi Tao had no reaction after touching the sapling. This basically indicated that he and Firefly's girls did not have the New type of symbiotic zombie virus in their bodies.
Moreover, none of the researchers on the fifth floor carried the New type of symbiotic zombie virus; otherwise, they would have shown symptoms of infection long ago. Thinking about it, Professor Yan's group of researchers had previously been closely guarded by the Wild Wolf Gang, researching potions day and night. Their status was low, almost isolated from the outside world, making the possibility of infection with the virus extremely small.
Zuo Feng returned the walkie-talkie to Professor Yan, his gaze refocusing on the monitoring screen. The two Six-Slash Zombies in the isolation chamber still maintained that eerie, almost feigned sleep state, with only faint chest undulations and occasionally rotating crimson eyes, indicating that they were not asleep, but rather accumulating strength and assessing the environment.
The A-grade metal chains, beneath their seemingly calm posture, remained taut, enduring continuous, immense, and unreleased tension.
This quiet, poised for action, was more frightening than their previous frenzied struggles.
Not long after, a dense sound of footsteps, approaching from a distance, broke the silence of the Laboratory.
Da Bai Tu, along with Firefly's girls and Da Mi Tao, quickly entered, their expressions serious.
Da Bai Tu and Firefly's girls' gazes instantly fixed on the monitoring screen, their faces revealing unconcealable shock. Although they were mentally prepared, seeing the Six-Slash Zombies still made them gasp.
Professor Yan, seeing that all the researchers had returned, quickly left for the deeper parts of the Laboratory to gather all personnel to discuss and formulate research strategies.
Zuo Feng put his arm around Da Bai Tu's shoulder and whispered, "Da Bai Tu, I need you to make a trip to H City and tell the leaders of the three major overlord-level forces to come here immediately. It's time we let them witness the true power of the pathogen."
Although Zuo Feng couldn't save H City, he still had to help where he could, letting the three major overlord-level forces understand the terror of the pathogen. As for how they would save themselves, that was their own business. This was all he could do to help.
As for the forces of Dream City, Zuo Feng had completely given up on them. Da Bai Tu had told him in a previous message that Mei Xue Ji, after joining Firefly, said that Wan Youyu was still frantically creating pathogens, and although Hu Banshan was not creating pathogens, he was still creating potions. Dream City was completely hopeless; they would soon fall into an abyss of eternal damnation.
Da Bai Tu nodded without hesitation, not a single superfluous word: "Alright, I'll go right away." Her turning motion was clean and swift, without any dawdling. As a core member of Firefly, she deeply understood the seriousness of the situation. The existence of the Six-Slash Zombies and the intelligence they displayed were enough to overturn everyone's understanding of this disaster.
She quickly walked out of the monitoring room, her figure rapidly disappearing at the end of the corridor.
Zuo Feng's gaze then fell on Little Maid, and he said, "You go to Huo Yao Base and inform Lu Zhuoyan to come here. Let him witness the existence of the Six-Slash Zombies as well."
Little Maid nodded in acknowledgment, accepting the order, and quickly left the monitoring room.
Zuo Feng looked at Da Mi Tao and said, "Da Mi Tao, you go to Sunshine Base and ask Luo Tianyu to come here as well." Da Mi Tao's eyes were firm, she nodded in agreement, and turned to walk out quickly.
The atmosphere inside the Laboratory grew increasingly tense, everyone preparing for the approaching storm.
Zuo Feng said to Da Yuanyuan, "Da Yuanyuan, you are responsible for preparing the reception work, ensuring that the leaders can quickly understand the situation upon their arrival." Da Yuanyuan nodded in acknowledgment and immediately began to arrange the reception matters.
Zuo Feng's gaze then fell upon the sapling. Upon seeing it, Zuo Feng couldn't help but chuckle. Mu Jingjing and Mu Lingling, the two little ones, were staring at the sapling, their mouths almost watering. Clearly, they had set their sights on the sapling's seeds again. Zuo Feng chuckled softly, "You two little ones, don't rush, there'll be plenty for you."
