The source of the sound was a mass of bushes about three or four hundred meters away from Zhou Yulong, these shrubs were no more than five meters high, and they were neatly planted on both sides of the road. Judging by the height and density of the bushes, these shrubs must have been planted by prison staff before the end of the world.

Zhou Yulong's speed was extremely fast, and in less than a second after the sound came out, he rushed to the edge of the bushes. The bushes were low, but they were so dense that they resembled a mass of low walls woven with branches, making it difficult to see what was inside. At this time, the things in the bushes seemed to be frightened, and they ran wildly. With the click of a tree branch being trampled on and bursting, Zhou Yulong vaguely saw a black streamer flying in the bushes.

"Hmph, stop me." Looking at the tiny black streamer, Zhou Yulong couldn't help but feel a little disappointed. Judging by the size of the streamer, it can't be a human, but more like a slightly larger cat or mouse. Thinking of this, he frowned slightly, condensed his right arm into a long blade, and slashed towards the bushes.

"Huh"

With a soft thud, the entire bush snapped in two under the silver blade. The black figure in the bushes also seemed to find that he was in danger, so after making a squeak similar to that of a mouse, he squatted down and stopped.

It has a long narrow body, a shaggy tail, shiny claws, and shiny black fur. This monster was the kind of mutant beast that Zhou Yulong had hunted at the bottom of the prison. If there is any difference between this mutant beast and the original one, it is that the one in front of him is faster, smaller in size, and more active in his eyes.

"This mutant beast, is it the evil seed left over from last time?" Looking at the little black beast squatting in place and grinning its teeth, Zhou Yulong couldn't help but shake his head. I thought I could find a survivor and ask what happened in the prison, but I didn't expect to find this little thing in the end. Thinking of this, he couldn't help but sigh with interest. Then he turned his right hand into a prototype and turned around and walked towards the lounge.

Whatever the original reason, he eventually killed the little beast's mother. It was not easy to think that this little guy could live alone until now, so Zhou Yulong was still determined to let it go. And judging from the signs of battle around the prison, the little beast should not have joined the attack that day. This is also another reason why Zhou Yulong faded away from his murderous aura and turned to leave.

"Squeak Squeak"

I don't know if I didn't feel the murderous aura on Zhou Yulong or this little guy was too arrogant, seeing Zhou Yulong turn around and leave, not only did it not escape, but it grinned with Zhou Yulong on its back. And it seems that just screaming is not enough, and the little guy also launched a direct attack. I saw it pick up a stone from the ground, then gently shook its head, threw the stone up, and at the same time turned around violently, using its long tail to shoot the stone towards Zhou Yulong.

"Heh, this little guy is upside down." Listening to the six ways and looking in all directions, although Zhou Yulong turned his back to the black beast, his behavior towards the little beast was clear. Feeling the sound of breaking the air coming from behind him, he smiled slightly, waved his hand and flicked it behind him, ready to bounce the stone back again.

"Smack"

With a soft sound, the stone turned into a ball of powder under Zhou Yulong's fingers, and covered the black beast with a sprinkled face, making a mess of its black and shiny fur.

"Squeak!"

Startled by Zhou Yulong's sudden counterattack, the little beast screamed directly, and then slammed towards another bush in the distance and disappeared.

"It seems that my control of power is still far from enough..."Looking at the black beast that disappeared into the bushes, Zhou Yulong couldn't help but shake his head, and he was secretly annoyed in his heart. He just wanted to shoot the stone bullet in front of the little beast to scare it, but he didn't expect that due to the excessive force, the stone was completely smashed into powder by him. Fortunately, this is a joke, if you still can't control your strength in battle, then the result is very dangerous.

"Squeak Squeak"

Just when Zhou Yulong was upset, the little black beast once again stuck out its head from the bushes in the distance, and then squeaked twice at Zhou Yulong. It was as if after that moment, it had determined that the human had no intention of harming it, so it became bolder.

"Well, I can't sleep at night anyway, so let's play with you little guy." Looking at the black beast's probing appearance, Zhou Yulong's mood was inexplicably much better. Then with a slight smile, he picked up a stone from the ground and threw it at the little beast "gently".

"Whoosh!"

Although Zhou Yulong didn't think that the force he used on the stone was not great, as soon as he made a move, the stone shot at the black beast with a violent sound of breaking through the air. The power on the stone was so great that the little black beast couldn't even react, so it was directly hit by the stone, and then flew out with a scream.

"I'm fainting, I'm heavy." Looking at the black beast that flew out upside down, Zhou Yulong frowned, and then rushed towards the black beast. It was a joke, and he didn't want to take the little guy's life.

'Squeak squeak!'

Just as Zhou Yulong rushed to the black beast's side, a mutation occurred. The little beast flying upside down suddenly screamed a few times, and then suddenly folded and shot in the air, inhaled violently, and aimed its butt at Zhou Yulong.

"Poof—"

As a roaring fart sounded behind the little beast, a dark green gas rushed towards Zhou Yulong at an extremely fast speed. Because the forward force was too great to control, Zhou Yulong could only watch as he crashed into this dark green gas.

"Holy shit, what kind of gas is this!" Although Zhou Yulong held his breath as soon as he entered the gas, the gas still drilled through his nostrils as if it was alive, and then went straight to his lungs.

Stinking! Stinking! Huge stench!

After the green gas entered his body, there was only one consciousness left in Zhou Yulong's mind, and that was stinky! In fact, to be honest, Zhou Yulong can be regarded as a person who has experienced all kinds of battles, but it is the first time he has smelled such a stinky smell. The stench of rotting corpses, the smell of cremation of corpses, all turned into puffy clouds before this stench. It seems that the only reason why this gas exists in the world is to tell humans what is the peak of smell.

This stench gathered the essence of all the stenches in the world, and without Zhou Yulong feeling it carefully, he could distinguish the various stenches that had the same end. There was the smell of rotting corpses, the smell of burning biological fat, the smell of dung, the smell of burning rubber, in short, as long as he could think of the smell, it was the best synthesis in this green gas. Smelling this smell, Zhou Yulong's eyes turned black for a while, and then after a few seconds, he finally couldn't support it anymore, retched and fell to the ground with a bang, and fainted.

However, this pain did not end with his fainting, in the coma, Zhou Yulong could still feel a stench lingering in his nasal cavity, and within a few seconds, he was awakened from the coma again, and then woke up for a few seconds and fainted. It wasn't until he woke up like this, I don't know how many times, that he got his wish and completely fainted.
