Wang Tianyu and Zhao Tian attacked with all their might, and soon each killed three burrowing leopards.

Now they have understood that if they want to evolve early and become stronger, they need to keep fighting and fighting to stimulate the potential in their bodies.

When they encountered this group of burrowing leopards, they did not flinch.

Xiao Han did not rush forward, but retreated to Li Quanlong's side.

Although the strength of the five of them has been strengthened to a certain extent, and they are holding wooden sticks in their hands, they are suddenly attacked by a group of burrowing leopards, and they are inevitably in a hurry.

When Xiao Han saw one of the burrowing leopards immediately pounce, he was about to bite Lin Chang'e's neck, and the bone tail behind him swung out and hooked into the ventral side of the burrowing leopard.

The huge bone hook sank deep into it and pulled it again.

The burrowing leopard's belly and internal organs were completely ripped open and scattered all over the ground.

The burrowing leopard couldn't even scream before it fell to the ground.

Lin Chang'e was frightened, grabbed the wooden stick with both hands, her chest rose and fell, obviously frightened.

At this moment, Shi Lei suddenly let out an angry roar.

Xiao Han turned his head to look, but saw that he was bitten by four burrowing leopards at the same time.

With a roar of rage in his mouth, he turned his body violently, and shook the four burrowing leopards away at the same time.

Then two more burrowing leopards pounced on him from behind and threw him to the ground.

Almost at the same moment, behind Shi Lei, something appeared like lightning.

The two burrowing leopards that had pounced on him roared and flipped out.

Shi Lei let out a wild laugh and had already turned over and stood up.

Behind him, something vibrated like a snake.

Just now, Shi Lei finally succeeded in making a breakthrough for the third time.

Like Xiao Han, his entire vertebrae seemed to come to life, extending out of his body, forming a tail that was two meters long.

But his tail is different from Xiao Han.

Xiao Han is a bone tail with a hook that is two or three meters long.

And Shi Lei's tail stretched out of his body, but it was a tail with a metallic color.

This tail, as if made of steel, has a dull metallic sheen on the surface, and there is no tail hook, and the tip of the tail is like a spike.

The surface of the metal is divided into countless knots, as if made of countless knots of metal rings, allowing it to bend freely.

This metal tail, when active, even faintly emits the crisp sound of "gurgling" metal rubbing.

Shi Lei felt that new power was boiling in his body, and his whole body seemed to have infinite power.

In particular, this metal tail, like the arms and fingers, even has a feeling of flesh and bone connected.

"Haha-"

He let out a wild laugh and took the initiative to charge towards the oncoming group of burrowing leopards.

These burrowing leopards are extremely ferocious, smelling blood, and even more violent, not afraid, and also pounced towards Shi Lei.

A burrowing leopard pounces from the side.

Shi Lei didn't need to look at it at all, his mind was everywhere, and the metal tail behind him swept violently.

Like a steel whip, it struck this burrowing leopard with a snap.

The power contained in it is at least more than a thousand catties.

In an instant, the burrowing leopard was beaten to pieces and turned upside down in the air.

Pumped the burrowing leopard, retracted it, and shot it like an arrow.

The sharp metal tail tip was like a spear, stabbing through the mouth of a burrowing leopard that opened its bloody mouth and pounced on it.

It goes down the throat, through the belly, and out from behind.

The burrowing leopard, which was pierced by a metal tail, stiffened, Shi Lei walked up, stretched out his left hand, and pushed it away.

The metal tail that pierced into it retracted, bringing out a stream of blood splattering.

And his strengthened right fist smashed into a burrowing leopard that pounced on the right at the same moment.

The burrowing leopard's seven holes immediately oozed blood, cracked its skull, and fell softly.

Killed three leopards in an instant, but it took only one breath.

His strength is strong, at least several times stronger than before.

And this thirst for killing made him feel uncontrollable pleasure, and Shi Lei was laughing wildly.

At this moment, in his eyes, this group of burrowing leopards is no longer a fierce beast, but his prey.

Wang Tianyu and Zhao Tian added a lot of wounds to their bodies, and both of them killed five burrowing leopards respectively.

Xiao Han easily solved ten.

Most of the caveworms were killed, and the remaining caveworms finally understood that the bipedal creatures in front of them were invincible.

Soon turned around and fled.

Watching the remnants of the cave-dwelling leopard escape, Shi Lei laughed wildly, and exhaled happily.

"That damn little ape-man, if I touch it again, I must ask it for the previous account!"

Shi Lei clenched his hands into fists, feeling the terrifying power contained in the metal tail.

Eventually, the tail was tucked into the vertebrae in his body and disappeared.

Witnessing Shi Lei's combat power and madness, Li Quanlong and the five were surprised.

Xiao Han and Wang Tianyu were also very surprised to see that Shi Lei's tail turned out to be metallic.

"It seems that we all thought wrong before, this tail should not be a real human with a tail, let alone some vertebrae extending out of the body, I estimate, this should be a kind of energy condensation formation, it is a kind of embodiment." Wang Tianyu pondered and reasoned.

Xiao Han said: "What do you mean, whether it is my bone tail or Shi Lei's metal tail, it should be formed by the materialization of the tail energy in our body?" ”

Wang Tianyu nodded and said, "It should be, I don't know the principle, but it should be through our vertebrae to materialize our tail force." ”

Xiao Han sensed with his heart, then nodded slightly, and said: "It should be like this, our vertebrae are like flashlights, and this tail is like a pillar of light illuminated by turning on the flashlight, or more accurately, this vertebrae is a kind of energy emission and converter, which excites the energy in our body, and my energy is excited outside the body, forming this bone tail, while Shi Lei's is a metal tail, the reason why it is different should be different from the essence of our energy, Otherwise, it is difficult to explain why Shi Lei appeared with such a metallic tail. ”

Shi Lei smiled: "I don't know the principle, anyway, it can be regarded as a tail or a weapon." ”

Although the injuries on the body are not light, the powerful tail force in the body is exerting a magical effect, constantly accelerating the healing of wounds.

Li Quanlong and Lin Chang'e, although they were also attacked by the cave leopard, fortunately, Xiao Han had been by their side, and they were not injured much, but they were not lightly frightened.

Seeing that the metal tail that Shi Lei had successfully awakened was amazingly powerful, Xiao Han also breathed a sigh of relief.

The strength of their team is getting stronger and stronger, and now even if the young ape-man appears again, he and Shi Lei should be able to deal with it together.

After that, the group continued on their way, going in the same direction as before.

They believe that no matter how vast this forest is, if they follow the same direction, they will one day leave here.

Feeling thirsty and hungry, the nine found a small cave.
