Sun Hu pointed to some gaps in the cave wall at this time, and said in a deep voice:

"Looking at this paw print, as well as the corpses of those fierce beasts in the valley, it can be deduced that there should be a saber-toothed leopard in this cave!"

Sun Long's face was solemn:

"Just now I found the corpse of a mountain moving ape in the valley, which shows that the strength of this saber-toothed leopard should have reached the level of a third-order fierce beast."

On the way here, Xiao Zhan already knew through the conversations of several people that in the chaotic world, fierce beasts can basically be divided into first-order, second-order, and third-order......

However, there is no unified standard for human beings to register their cultivation in the chaotic world.

Therefore, when facing a person, if the other party does not show his aura, it is difficult for you to judge the strength of the other party.

Sun Hu exhaled a breath of turbid air at this time, and said in a deep voice:

"The four of us are not afraid of a saber-toothed leopard who has reached the third order."

"The saber-toothed leopard has a keen sense of smell and is incredibly fast, a pair of saber-toothed teeth are sharp and indestructible, the claws are also extremely sharp, and the head is extremely hard."

"Once you fight, remember not to get bitten and attack its tail as much as possible, that is its Achilles' heel!"

"I'm at the front, the second one is behind me, and then the third one, Brother Xiao, you don't have much experience, so you'll follow behind, but be careful, you must be vigilant!"

"Let's keep a distance of three feet."

After speaking, Sun Hu walked directly into the cave.

Sun Long followed closely behind, followed by Sun Yiran.

Xiao Zhan was at the forefront.

It was pitch black in the passageway, but all four of them could sense their surroundings.

The passage was hot and humid, and the walls of the cave were covered with moss and mold.

I don't know how long I walked, but Sun Hu, who was walking in the front, suddenly spoke softly and signaled to stop.

"Wait a minute, I don't feel right!"

After speaking, Sun Hu was alone and cautiously turned the corner.

After a while, Xiao Zhan and the three of them couldn't feel Sun Hu's breath.

For a while, a tense atmosphere spread.

Sun Long suddenly whispered:

"Little sister, you and Brother Xiao are waiting here, I'll follow and take a look, so that the eldest brother won't have an accident."

Sun Yiran exhaled a breath of turbidity:

"Second brother, I'll be with you too!"

Sun Long decisively refused, and then rushed out as fast as he could.

However, Sun Long's aura also disappeared soon after.

Sun Yiran was obviously more anxious.

She turned around and said to Xiao Zhan behind her:

"Brother Xiao, stay here by yourself, you must pay attention to your safety, and if anything is wrong, flee immediately!"

After speaking, Sun Yiran also rushed forward.

Xiao Zhan did not choose to stay where he was, but followed behind Sun Yiran.

The passage twisted and turned, but Xiao Zhan could feel that the passage was extending downward.

After a while, a faint light suddenly appeared in front of me.

A river of magma that flows slowly underground.

The temperature here was extremely high, even if it was still a few tens of meters away from the magma river, Xiao Zhan was extremely uncomfortable.

At this time, Sun Long and Sun Hu fell by the river, their breath extremely weak.

Seeing this scene, Sun Yiran's pupils shrank sharply, and he immediately rushed towards Sun Long and Sun Hu.

"Stop!"

Xiao Zhan suddenly burst into a shout:

"That's an illusion!"

But Sun Yiran had already rushed to the riverside and stretched out his hand to grab his two elder brothers.

In the next moment, Sun Hu and Sun Long's bodies disappeared.

A fierce beast with a body length of more than five meters and gray-brown markings all over its body opened its bloody mouth, and its two sharp fangs were half a meter long, and it bit towards Sun Yiran.

Xiao Zhan's eyes lit up, and the black dragon spear instantly appeared in his hand, and a spear instantly flew past Sun Yiran's body and bombarded the head of the saber-toothed leopard.

"Bang!"

The guns exploded.

The saber-toothed leopard's head was dripping with blood, but only its skin was broken.

This only angered the saber-toothed leopard, which roared violently and jumped towards Xiao Zhan.

Not only that, Xiao Zhan also felt that the picture in front of him had changed, he actually saw Ye Wei, Xiao Yao and Xiao Tianxia!

"Brother Xiao be careful!"

Sun Yiran's shout made Xiao Zhan suddenly sober up.

And the saber-toothed leopard had already pounced in front of Xiao Zhan, its sharp and thick claws slapped at Xiao Zhan's heart, and the huge wind almost crushed Xiao Zhan.

The two half-meter-long sharp teeth also bit into Xiao Zhan's head.

Xiao Zhan's eyes flickered, his wrist flicked, and the black dragon spear stabbed towards the saber-toothed leopard's mouth.

"Bang!"

The saber-toothed leopard twisted its head, and its teeth collided with the black dragon spear.

The huge collision force suddenly made Xiao Zhan a little unable to hold the black dragon spear, and the whole person flew out backwards behind him.

The saber-toothed leopard's teeth burst into sparks, and they didn't break! Just left a scratch.

Sun Yiran had already taken out his sword at this time and rushed forward, raising his hand to stab out a series of sword rays, heading towards the saber-toothed leopard.

"Bang!"

The sword light slammed into the saber-toothed leopard's body, and it only pierced the skin, leaving shallow wounds.

This only angered the saber-toothed leopard even more, and its long and thick tail flicked violently, like a steel whip, and it was slammed towards Sun Yiran.

Sun Yiran couldn't dodge, and hurriedly raised his sword to block.

"Bang!"

In the next moment, I saw that the sword in Sun Yiran's hand was broken, and his body flew out upside down, and he was about to fall into the magma river in the next moment.

Xiao Zhan kicked a rock on the ground violently.

The stone flew out at a faster speed and hit Sun Yiran's body, changing the direction of Sun Yiran's fall, making her hang by the magma river, only less than ten centimeters away from the churning hot magma.

Sun Yiran hurriedly endured the severe pain and got up, looked at Xiao Zhan with palpitations, and wanted to step forward to help, but found that the saber-toothed leopard had already chased Xiao Zhan into the passage.

Sun Yiran gritted her teeth and hurriedly followed.

But she soon found that there was only one passage when she came, and when she went out at this time, the passage was full of directions, and she didn't know how many holes there were.

Obviously, from the moment a few people came in, they were already in the illusion created by the saber-toothed leopard.

I don't know if it's lucky, Sun Yiran saw the blood on the ground, rushed into one of the holes, and didn't take long to see Sun Hu and Sun Long.

Both of them have been seriously injured, and their faces changed greatly when they saw Sun Yiran:

"Little sister, didn't you ask you to wait outside!"

Sun Yiran said anxiously:

"Big brother and second brother, I'm worried about you!"

Sun Hu struggled to get up and hurriedly asked:

"Brother Xiao Zhan!"

Sun Yiran's voice was already filled with crying.

"Brother Xiao lured that saber-toothed leopard away in order to save me!"

"Big brother, second brother, let's hurry up and save Big Brother Xiao!"

Sun Long and Sun Hu glanced at each other:

"Second brother, it was Brother Xiao who saved us, and now he has led away that beast in order to save my little sister! We can't abandon him!"

Sun Long nodded, without any nonsense, and immediately rushed out.

But the number of passages in this was too many to count, and they couldn't tell which passage Xiao Zhan had taken.

Moreover, they do not feel the breath of the saber-toothed leopard.

At the same time, Xiao Zhan was running wildly in one of the passages.

Behind him, the saber-toothed leopard had already caught up.

Xiao Zhan kept turning around and brandishing the black dragon spear to attack, and the saber-toothed leopard was scarred, but it was only skin wounds.

The little gray patriarch reminded at this time:

"That Sun Hu said that the weakness of this beast is in the tail

on."

Xiao Zhan naturally remembered this.

But he couldn't find a chance to attack the saber-toothed leopard's tail.

Suddenly, another passage appeared on the right.

Xiao Zhan's eyes froze, and he immediately gathered all his breath and turned into the side passage.

The moment the saber-toothed leopard followed, Xiao Zhan shot out violently.

A piercing spear instantly bombarded the saber-toothed leopard's tail.

"Flutter".

Blood splattered, and the saber-toothed leopard let out a painful roar, its tail already broken and fell to the ground.

As if it had lost its balance, the saber-toothed leopard instantly slammed into the cave wall, but it quickly turned its head and slapped its thick claws at Xiao Zhan.

Xiao Zhan didn't expect it to react so quickly, it was slapped in the chest, and he only felt like he was about to be crushed.

However, because of the loss of balance, the paw of the saber-toothed leopard did not hit Xiao Zhan's heart, but grazed his heart, taking away a large piece of flesh and blood.

Xiao Zhan turned around and rushed out of the cave, escaping as fast as he could.

The saber-toothed leopard roared and rushed out, but it swayed left and right, constantly hitting the cave wall, and it couldn't even run normally, and its speed was even slower by more than half.

Xiao Zhan breathed a sigh of relief.

He didn't run away, but waited for the saber-toothed leopard to rush to the right distance, fired a shot with all his might, and then turned and fled again.

After repeating this for dozens of times, the saber-toothed leopard finally couldn't hold on, and fell into the passage with a roar, its strong body almost blocking the entire passage.

For the sake of safety, Xiao Zhan fired several shots in a row, and only after making sure that it was dead did he approach again.

This saber-toothed leopard's flesh and bones can carry so many things, and it is obviously a good baby.

And that pair of teeth, which are definitely good things for refining weapons.

With a wave of his hand, Xiao Zhan collected the body of the saber-toothed leopard into the second-level world in his body.

The voice of the little gray patriarch sounded in Xiao Zhan's mind:

"Xiao Zhan, I'll refine a set of soft armor for you, as well as two weapons."

Xiao Zhan nodded, then sat down and began to adjust his state.

Half an hour later, Xiao Zhan got up and looked at the surrounding passages.

He couldn't tell where he was now, so he could only try his luck at a random one.

Xiao Zhan raised the black dragon spear, made a mark on the cave wall, and then walked deeper into this passage.

After dozens of attempts, Xiao Zhan returned to the passage that had been marked in the first place.

He closed his eyes and merged the routes he had taken, trying to sketch out the overall layout of the passages in his mind.

After thinking for a while, Xiao Zhan chose a route according to his memory, and after more than an hour, he entered a straight and flat passage.

At the end of the passage is a boxy stone chamber.

Above the stone chamber, there is a milky white translucent bead that is emitting a lustrous light, illuminating the entire stone chamber.

Xiao Zhan muttered in a low voice:

"It's a luxury to use a world bead as a lighting tool."

After saying this, Xiao Zhan looked at the simple and heavy gray sarcophagus in the middle of the stone room.
