"What? You're unwilling?"

Seeing Yin Gang hesitate, Leopard asked grimly.

"Of course not!"

Yin Gang immediately shook his head. He was already in the center of the zombie horde. Refusal meant instant death. So, he stepped forward, looking at Leopard, and said,

"Let's do it!"

"Very good!"

Leopard nodded, and just as he was about to bend down, Yin Gang spoke again:

"Wait! You…it's best not to bite in a too obvious place, because I need to go out as a human. If people see bite marks, then…"

"That's simple!"

Leopard nodded, then extended his right hand. In it, he held a glowing bead. Then he extended a finger, signaling Yin Gang to drop his pants. He then used his sharp fingernails to prick Yin Gang's inner thigh.

Yin Gang looked at the bead, a flicker of obscure light passing through his eyes.

"Alright! Remember, you must return here within a month, otherwise, the virus here will explode, and you will become a zombie within a minute of the outbreak!"

Leopard retracted his hand, put the bead away, and said,

"Okay! Now, tell me which direction you want to leave the city from?"

"That way!"

Yin Gang pointed to the east of the city.

"Li Chenzhou and the others didn't leave in this direction."

Leopard frowned.

"I know!"

Yin Gang nodded:

"I can't let Li Chenzhou and the others find out yet, so I need to stay away from them first! When I develop, it will be time for us to kill him! I am not their opponent yet. You saw their abilities just now. I need time!"

"Hmm! Perhaps I can help you with that."

Leopard looked at Yin Gang, then with a thought, a strengthened zombie walked in and stood before Leopard.

"Poof!"

Leopard swiftly extended his palm, crushing the strengthened zombie's head. He then flipped his hand open, and within the fragmented flesh and brain matter in his palm, a crystal core lay quietly.

"Eat this!"

"Eat?"

Yin Gang looked at the crystal core covered in red and white matter, reeking of zombie stench, and felt a wave of nausea.

"What do you think made Li Chenzhou and the others so powerful?"

Looking at Yin Gang's expression, Leopard said coldly.

"You mean, they ate this stuff too?"

Yin Gang's eyes widened.

"Of course, it's called a mutated crystal core. If humans want to become strong, they must absorb this thing!"

Leopard said. In his heart, he believed that Li Chenzhou and Grey Bear had become ability users by absorbing mutated crystal cores. He had no idea that there was such a heaven-defying thing as an evolution potion.

"Hoo!"

Hearing Leopard's words, Yin Gang took a deep breath, reached out, and took the crystal core.

He didn't doubt Leopard, because Leopard had no need to deceive him now. If he wanted him dead, why would he need a crystal core? Just a slight deviation of his finger earlier would have done the trick.

Wiping the crystal core on his clothes, Yin Gang closed his eyes and put the crystal core into his mouth…

A few minutes later, Yin Gang got up from the ground, his eyes flashing with excitement. He had become an ability user, and not just a strengthened one, but an evolved one, possessing skills!

Feeling the power within him, Yin Gang clenched his fist tightly, then suddenly knelt down to Leopard, kowtowing three times forcefully on the ground:

"Great Zombie King! From today onwards, I am your most loyal dog. Whoever you want me to bite, I will bite. Don't worry, one day, I will deliver that Li Chenzhou trash to you, so you can personally kill him and tear him to pieces!!!"

"No! I will not tear him to pieces. I will make him a zombie, to serve me forever!"

A sneer appeared on Leopard's face, then he added:

"This is just a level one crystal core. Work hard, and in the future, I will give you even higher-level crystal cores. No one has more of these things than me!!!"

"Yes! My King! I understand!"

Hearing that there would be more in the future, Yin Gang even changed his address!

"Alright! Go do what you need to do!"

Leopard looked at Yin Gang, then summoned a Tyrant:

"I'll have it follow you. It will temporarily obey your orders. When you think it's okay, just let it return on its own!"

"How…how do I command it?"

Looking at the Tyrant in military uniform, Yin Gang hesitated.

"Just speak directly. It understands!"

Leopard replied.

"Alright! My King, then I'll leave first. I will definitely be back within a month, and I will report my achievements to you. I will deliver a satisfactory answer!"

Yin Gang knelt down again and kowtowed.

Before, he only bowed, but that crystal core made him completely change his etiquette!

"Wait! Take these with you! You'll need them!"

Leopard turned and went to a shelf, took down a pistol, a rifle, and a pile of bullets, and handed them to Yin Gang:

"Can you use them?"

"N-no!"

Yin Gang shook his head. Before the apocalypse, he was just an ordinary person, with no chance to come into contact with firearms.

Leopard tossed the guns to the Tyrant and said:

"Have him teach you. Learn it before you leave!"

The Tyrant took the gun, walked to the table, turned back and stared at Yin Gang with blood-red eyes. Yin Gang hurried over, and the Tyrant actually began to demonstrate how to use the firearms, even using his hands to correct his posture, and his movements were quite skilled, as if he had taught many people before.

It took a full hour before Yin Gang finally learned how to use the firearms, and even tried firing a few bullets in the room. Anyway, this was the Zombie King's territory, and the sound could not attract any zombies.

And when shooting, whether intentional or not, the Tyrant actually had him shoot in the direction behind Leopard. If Yin Gang wanted to, as long as the muzzle was tilted up twenty degrees, he could shoot the bullets at Leopard.

Having seen Leopard fight Li Chenzhou and the others before, Yin Gang knew that Leopard could not withstand bullets. He had personally seen Leopard's arm broken at the time.

Of course, the current Leopard had completely recovered. Yin Gang didn't know how he recovered, but he at least knew that Leopard had only been hit by one bullet at the time.

But now, the rifle in his hand had thirty bullets. Even if they were all shot at Leopard's head, no matter how strong his recovery ability was, it would be useless.

Even if Yin Gang's marksmanship wasn't very good now, he should be able to hit at least a dozen rounds at such close range, right?

Thinking so, Yin Gang loaded a full magazine, pulled back the bolt, then slowly raised the rifle, closed his eyes, aimed for a moment, and then forcefully pulled the trigger…
