Reborn as a tiger, he was chosen by the nation as its guardian beast.

Qin Tieshan was getting on in years, and after staying up most of the night, he had just dozed off in his chair when he was suddenly awakened by the noise.

He sprang up from his chair almost instantly, his old but sharp eyes showing no trace of the confusion of just waking up, only the vigilance of someone who had been through countless battles.

Then, he immediately saw Wang Hu standing in front of him, looking spirited and even exuding a faint murderous aura.

And there were three clumps of minced meat on the ground, oozing a dark green liquid.

"Enemy attack!"

"Protect the leader!"

"alert!"

The command center instantly descended into chaos.

Some people shouted in panic, some had already drawn their pistols and quickly moved closer to Qin Tieshan, forming a human wall, while others had already run outside with their guns, trying to check the situation.

Just as the whole scene was in chaos, Qin Tieshan's powerful voice suddenly rang out.

"Shut up, all of you!"

"What's the panic? Is the sky falling down?"

He shoved aside the guards blocking his way and strode into the center of the field.

"Everyone, get back to what you were doing!"

"Go, bring Dean Gu over here!"

The old general's authority was on full display at this moment, and the previously chaotic command center instantly fell silent.

Everyone subconsciously straightened their backs, then quickly returned to their positions and continued with their work, though their peripheral vision kept glancing this way.

After seeing everyone off, Qin Tieshan turned around and walked up to Wang Hu.

He looked at the three still-wriggling clumps of flesh on the ground, and then at Wang Hu's still vigilant posture. He understood perfectly what had just happened.

With a solemn expression, he bowed deeply to Wang Hu.

"Big Cat, thanks."

"You saved my old life today."

Wang Hu grinned, revealing his sharp teeth.

He glanced at the tray not far away, which was still full and even had a few more blue crystal cores. He couldn't help but yawn, his imposing aura quietly fading away. He leisurely walked back to his seat, picked up two crystal cores and put them in his mouth, crushing them with a "crunch".

His meaning was clear: he was always ready to take advantage of any benefits.

Looking at his appearance, Qin Tieshan couldn't help but smile.

This tiger is really... quite interesting...!

Soon, Gu Xing, the director of Huacheng Extraordinary Biological Research Institute, arrived with two assistants, sporting two huge dark circles under his eyes.

He had clearly not slept all night, and his whole being exuded a sense of utter exhaustion.

"Sir, you wanted to see me?"

As soon as Gu Xing entered, he saw the three new-type zombies on the ground that Wang Hu had smashed into mincemeat. He was stunned at first, and then he and his assistant squatted down to study them.

"Another new type of mutant that we've never seen before."

"This is the eighth one already..."

"How can there be so many mutants? Is this even scientifically possible?"

Gu Xing looked incredulous. Perhaps due to overworking his brain, he had eaten crocodile meat a few days ago, and the hair that had grown back on his forehead had disappeared again without him noticing. At this moment, his forehead looked even shinier under the light.

An advisor quickly pulled up the alarming footage that had just been captured by the surveillance cameras and placed it in front of him. Immediately, large beads of cold sweat dripped down the forehead of this highly respected old dean in the research field.

In the surveillance footage, three almost completely transparent mutants, barely noticeable without close inspection, silently infiltrated the command center, their target clear: Qin Tieshan, who was resting with his eyes closed.

Their speed and stealth were simply impossible to defend against.

If Wang Hu hadn't reacted so quickly, the consequences would have been unimaginable!

As the person in charge of researching zombie species during this exploration of another world, he failed to provide advance warning of the existence of these invisible zombies. If something were to happen to the commander-in-chief, he would definitely be held responsible.

Even though he hadn't slept a wink all night, studying the endless stream of mutated zombies, it was still the same.

Thinking of this, he couldn't help but glance gratefully at Wang Hu, who was happily eating in the corner.

Only then did he force himself to cheer up and have several assistants carefully collect the three piles of minced meat and take them back to the temporary laboratory.

He himself took this opportunity to report to Qin Tieshan on the changes in the entire zombie horde throughout the previous night.

"Sir, starting from the latter half of the night, new mutated species of zombies have been constantly appearing in the horde."

"At first, they only appeared sporadically, but by the early morning, the number of mutants had increased significantly."

His words carried an undeniable weariness and worry.

"Currently, we have observed three main types of variants."

"The first type has hardened bone armor growing on its body surface, making it difficult for our standard rifle bullets to penetrate its defenses. Moreover, this type of mutant is extremely resilient; even if it loses an arm or a leg, or even has half its head blown off, it can still move around."

"The second type is extremely fast, running on all fours, and can even leap several meters high, moving between buildings with great agility."

"The third type is the giant mosquito we encountered before. Now they have grown thicker exoskeletons, making them not only faster at flying, but also with sharp spikes on their forelimbs, posing a great threat to our soldiers on the front lines."

Qin Tieshan listened quietly, his brows furrowing unconsciously.

He had actually received these reports from the front lines.

"Where did these mutants come from?"

"Are you sure?" Qin Tieshan asked the question that concerned him most.

Gu Xing nodded, his expression solemn.

"After working through the night to study and analyze, we can almost confirm that these mutants were not originally there, but were temporarily transformed from ordinary zombies."

"Moreover, the rate at which this mutant is transforming is accelerating at a speed beyond our imagination!"

"If left unchecked, I suspect that before long, all the zombies in this city will have transformed, and even more bizarre mutant species will appear!"

"Just like... those three mutants that just raided the command post, capable of optical cloaking."

He added, emphasizing again the seriousness of the matter.

"Furthermore, we have reason to suspect that these mutated zombies are directly controlled by those intelligent beings underground, and their combat intelligence is generally very high."

"This assassination attempt is the best proof."

Qin Tieshan nodded, indicating that he understood.

He finally realized that these zombies from another world were far more troublesome than he had imagined.

The reason why we performed so poorly last night was largely because we were caught off guard by our own side.

Now that the other side has realized what's happening, the real battle is just beginning.

"The key is still those guys hiding in the shadows underground."

He hesitated for a moment, then turned back to his desk, picked up a communicator, and dialed a number.

The call was connected quickly.

Qin Tieshan didn't waste any words and went straight to asking the question.

"Is our package ready?"

A series of chuckles came from the other end of the communicator.

"Reporting, sir! Our logistics department worked overtime overnight and just finished setting up the launch pad!"

Upon hearing this, Qin Tieshan also revealed a cold smile on his face.

"The thing underground just gave me a big surprise; it almost killed this old man."

"As the saying goes, it is impolite not to reciprocate. Our country, China, is a land of etiquette. Since the other party has given me a gift, shouldn't I return the favor?"

As Qin Tieshan finished speaking, he raised his wrist and glanced at his watch.

"I want to hear a noise in fifteen minutes."

"Furthermore, we need to inflict as much damage as possible on the enemy, is that alright?"

The laughter on the other end of the communicator vanished instantly, replaced by a solemn and absolutely confident assurance.

"Reporting to the commander, mission accomplished!"
