The steel thorn did not move, and with the momentum of the ferocious Zerg puppy, the sharp tip of the steel thorn pierced deep into the throat of the Zerg puppy, passing through the mouthparts, and almost piercing out of the head.

Zhang Yuan let go of his hand and quickly took a few steps back, his posture light and swift, without dragging his feet. With a click, the ferocious Zerg puppy almost used all his strength to close the giant mouth and bite the steel thorn's handshake. Although its incisors can gnaw almost a qiē rock, they are not as hard as this thickened alloy steel. With a click, the steel immediately bent, and the teeth of the male Zerg puppy could no longer penetrate deeply.

Zhang Yuan raised his right leg and stepped on the head of the Zerg puppy of the male Zerg puppy. The male Zerg puppy squeaked and wailed, but the Zerg puppy's head could not be lifted from the ground at all. As soon as it exerts force, the body pierced by the steel thorns will be filled with unbearable pain. Even with the trauma, it struggled for more than a minute before it stopped breathing.

The steel thorn that fell on the body of the male Zerg puppy was already bent, and Zhang Yuan had no intention of using it again. He took out a triangular steel spike from behind his back and held it in his hand again, and continued to walk into the darkness. In the base, Zhang Yuan polished several such melee weapons.

Even in the dark and rugged cave, Zhang Yuan's eyes and rich experience could distinguish the traces of the ferocious Zerg puppy, and it didn't take long for him to find the lair of the ferocious Zerg puppy. There are more than 30 fierce Zerg puppies of all sizes in the nest, the big ones are almost adults, and the small ones have not yet opened their eyes, and it can be seen that these Zerg puppies are the cubs born by the adult female Zerg puppies just now.

The steel thorn in Zhang Yuan's hand swept away, and a fierce Zerg puppy flew back, blood spurted wildly from his neck, and after hitting the cave wall and falling, he couldn't get up again. The sticky spikes swept away, and seven or eight little Zerg puppies instinctively opened their mouths to bite something. However, the spikes in Zhang Yuan's hands were instantly pierced, and almost all of their heads were pierced.

A minute later, the litter of ferocious Zerg puppies was completely wiped out. The ferocious Zerg puppy is a creature with a very strong sense of territory, and with this litter of Ferocious Zerg puppies, then there should be no second litter of Zerg puppies within a kilometer nearby.

Zhang Yuan took out a map, supplemented the topography of this passage in the blank part above, marked the location of the Zerg puppy kennel, and then carefully put the map away.

A few hundred meters further along the slippery cave tunnel, Zhang Yuan stopped at a collapsed site. Behind the mound of earth revealed a hole that could only be crossed by one person. On the other side of the cave is a labyrinthine passage, deep and full of unknown dangers. Coming here, it meant that the prize money of five hundred yuan and a gallon of water had fallen into his pocket, and on the other side of the hole, a branch of genetic mutation evolution potion was tempting him.

Zhang Yuan knelt at the entrance of the cave and listened. The wind blowing from the abandoned Protoss underground base fluctuated in strength and weakness, and there was a faint rustling sound inside.

That kind of sound indicated that there were groups of Zerg puppies roaming inside, Zhang Yuan listened for a while, confirmed that there were no dangerous creatures clinging to the hole over there, and then took out the handcuffs, and gently jumped into the tunnel of the abandoned underground base of the Protoss, and then made a long jump, bowing down quickly. He walked fast, but there was no sound under his feet.

In front of the passage, the chaotic sound gradually became louder, and the unique stench of the Zerg in the air became even stronger. Turning a corner, you can see the ruins of the Protoss buildings there, blocking most of the entire passage. The ruins made of steel have long since been rusted to the point that they are not looking good, and countless broken metal residues are scattered on the ground.

Through the doors and windows, you can see that the outermost Zerg is rummaging around, looking for something to eat. Zhang Yuan observed the surrounding environment for a moment, moved quietly, carried a steel thorn, and quietly dived towards the ruins of the building.

Bite! Zhang Yuan gently knocked on the broken metal wall. The sound of percussion was not loud, but in Zhang Yuan's keen hearing, any sound that was not in harmony with the surrounding environment was like thunder. The two Zerg puppies immediately stopped rummaging for food, turned around together, and saw a figure disappearing outside the door and window. In the eyes of the animal-instinctive Zerg puppy, anything that moves is a delicious prey.

With a roar, the Zerg puppy rushed to the end of the broken wall like lightning, and the Zerg puppy in front jumped up, smashed the broken plexiglass doors and windows, and squeezed out of the doors and windows with half of his body. As soon as he poked out of the door and window, the Zerg puppy couldn't wait to look left and right, trying to find out the traces of his prey.

With a soft thud, sharp alloy steel spikes pierced from below, easily piercing its throat and even cutting off most of its neck bone! Zhang Yuan stood up slowly, ignoring the Zerg puppy who tried in vain to pull out the sharp iron cone, and walked straight towards the passage.

The other Zerg puppy that was blocked in the wall had long since lost patience, and it roared, grabbed the leg of the Zerg puppy in front of it, and pulled it back into the wall. The sharp plexiglass and metal shards on the window frame cut seven or eight deep wounds into the body of the previous Zerg puppy, and black and red blood mixed with blood clots flowed down. But neither Zerg puppy cares. The Zerg puppy covered in blood was approaching the end of its life, and another Zerg puppy hurriedly squeezed out of the door and window, just in time to see Zhang Yuan's back disappear from the corner.

The Zerg puppy straightened its neck and roared fiercely before it suddenly exerted its strength, and its hard, long clawed feet stomped on the ground fiercely, rushing through the corner of the passage like a gust of wind!

The Zerg puppy that was almost running up and flying suddenly really flew off the ground! It swung violently in the air several times before falling heavily from the wire. As soon as it hit the ground, it immediately roared in pain! At this moment, sharp alloy spikes had pierced deep into its chest, and the stabbing stabbed upwards through its head.

With a crisp click, Zhang Yuan opened the handcuff safe. He walked past the Zerg puppy on the ground, who was already in an unconscious struggle, and didn't pay any attention to it. He raised his head slightly and glanced upwards, and then jumped slightly, and the whole person rose lightly more than two meters high, and had reached the top of the ruins of the abandoned building.

A trace of cold light suddenly flashed in Zhang Yuan's eyes, and he suddenly exerted his strength, running along the ruins of the building like lightning at a speed far exceeding that of the Zerg puppy! Even with his bow and gallop at such speed, he barely made a sound. From behind, it looks like a black mist rising away.

Bang! Bang! Two thunderous claps shattered the silence of the abandoned Protoss' underground base. In the wall of the ruins of the building, two Zerg puppies were shot in the head, and the huge force of the bullet almost lifted their entire bodies away, and the heads of each Zerg puppies broke a fist-sized blood hole!

Bang bang! Four more almost connected bangs sounded, and Zhang Yuan had already rushed to the end of the ruins of the building. He didn't stop for the slightest, he jumped directly from the top of the ruins, and there were several soft sounds in the air of the corpse of the Zerg puppy falling to the ground, and when Zhang Yuan stepped on the ground again, the bullets in the handcuffs had been reloaded.

With the force under his feet, his speed increased by three points, and he passed a ten-meter-long passage in an instant. Zhang Yuan seemed to turn into a gust of breeze and passed by the four Zerg puppies who were running quickly in the passage!

Zhang Yuan suddenly stood still, his body was twisted extremely stiffly, and his backhand was three guns! The three Zerg puppies should fall down. And the other Zerg puppy turned around in time and roared and pounced on Zhang Yuan!

Zhang Yuan looked at the Zerg puppy quietly, not moving. The Zerg puppy only rushed a few meters forward and fell headlong.

Zhang Yuan's right hand was holding a spike at some point, and the moment he passed by just now, it was this dagger that completely pierced the back of the Zerg puppy's neck.

Zhang Yuan turned around and looked at where the four Zerg puppies came from. At the end of the passage, sure enough, two more Zerg puppies appeared, and the strange thing was that these two Zerg puppies were biting the body of an adult ferocious Zerg puppy together. From their red eyes and drooling mouths, Zhang Yuan could tell that they were hungry.

However, they did not touch the food in their mouths, which was completely inconsistent with Zhang Yuan's cognition. Zerg puppies have always been the only purpose of survival to satisfy their appetite, and they don't know what moderation is. If you throw enough food at them, they will most likely eat it until they die.
