Leo clenched his fists.

The contract rock bear is not a benefit at all.

Bear Power: Summons a war beast, and the master of the contract can get the power bonus of the war beast itself.

For an ordinary summoner, adding the power of a rock bear out of thin air is extremely impressive, but Leo is a little disappointed.

Leo would have been much happier if the Rock Bear's bear power had been a percentage bonus to Leo's own strength. Directly increasing the strength of a rock bear is a greater increase in the short term, but Leo will definitely climb the god realm again in the future.

Return to the realm of God.

The increase in the strength of the bear is extremely small, and it is like a chicken rib.

Therefore, a skill that can increase Leo's own strength by a percentage is a truly useful skill.

"Let's go!"

Leo never expected a black iron-level rock bear to have a skill that would benefit him for life, anyway, it was used to confuse outsiders, which was just right.

The cave passage winds around.

Meandering.

Walked out two or three thousand meters.

The Wolf of Shadows discovers that there are digging bugs in front of him.

The burrowing insects with their armor shells resemble the iron-skinned rhinoceros that live in burrows, and are even larger.

The two Shadow Wolves can banish them, but it is unlikely that they will inflict massive damage on them. The characteristics of the digging insects are that the carapace is extremely thick, and the vitality is super strong, even if they are injured, they can recover by eating a little dirt, and if you want to kill them, you must cut off their heads. For this kind of earth-digging insect with infinite strength and armor, which usually hides in the ground and burrows and eats mud to live, there are really not many natural enemies.

Leo wasn't interested in dealing with this kind of underground powerhouse who liked to devour minerals.

Just leave.

The group of digging insects was unfazed by Leo's passing, and continued to dig in the soil one by one.

Except for a small digging worm, I don't know whether it was frightened or naughty, and spit a mouthful of corrosive dark green saliva at Leo from afar.

Naturally, Leo couldn't have hit, but he almost splashed the rock bear at the back of the team.

The rock bear growled loudly at the little creature in annoyance.

Roar!

It's just that Leo doesn't stop.

The other party is a big family living in groups, and it knows that it can't fight hard, so it has to glare at the other party angrily, turn around and spread its steps, and hurriedly chase after the master.

Five or six hundred meters ahead, there is a stone door blocking the way through the cave passage, and when the stone door is opened through the mechanism, a huge cave opening is presented in front of you.

Looking ahead, Leo found that it was a large rift valley formed inside the mountain, and although the sun did not shine in the underground, it was full of life.

Big-eared bats, stone lizards, cave spiders, cryptopteras, dark scorpions, and underground blind snakes.

I borrow advantageous place type to open a meal.

They prey on large swarms of flying insects.

Buzz.

One moment a group flew over, the next a large group flew over, and they densely occupied the sky in the rift.

The number of flying insects is so large that the various natural predators that feed on them are nourished to the fullest. Leo was not very interested in the ecology of the interior of the rift, and he sniffed hard and smelled a peculiar stench.

Leo nodded.

It's the peculiar smell of dragon flies, yes.

In an environment where flying dragons live, dragon flies generally appear.

Dragonflies are not closely related to Wyverns, they belong to a very strange symbiotic relationship with each other.

In addition to hunting on their own, dragon flies also like to follow the wyvern in groups and eat the food scraps of the wyvern. Wyverns, on the other hand, can quickly spot large prey on the ground through the guidance of dragon flies, and they are very satisfied that they always have a group of guides to point out their goals when they need to eat.

In addition, many insects like to lay eggs in the excrement of wyverns.

And the dragon fly catches on to that.

Lay eggs in the same place.

The ferocious dragon fly larvae are born knowing how to prey on a variety of nutrient-rich maggots and nourish themselves.

"Woo, woo, woo......"

Over the Rift Valley.

Suddenly, there was a chaotic and characteristic buzzing hiss.

Dozens of nearly 100 strange creatures with a body length of more than one meter that resemble the appearance of a large dragonfly but have sharp stinging needles on their tails, this kind of fierce demon insects that are still larvae when they hatch out are black iron level, and use their superb flying skills to carry out a playful hunt against the insect swarm that cannot be evaded.

In the sky, other creatures withdrew from the hunting grounds, fearing that they would become one of the other party's tables.

Several dragonflies spotted Leo, and they didn't hesitate to pounce on them, accustomed to being at the top of the food chain in the Underground Rift.

The mouthparts open.

Hideous teeth were bared.

"Want to eat my meat, you've found the wrong person!" Leo unhurriedly took out the black diamond in his arms, and with a light pull of the source energy, a dark green nether fire 'boomed'.

With the movement of Li Aoxin's hand, the green flame fanned out into the sky dozens of meters in front of him, and everywhere he passed was invincible.

Those arrogant dragon flies were instantly burned into charcoal, and the flying insects around them turned into flying ashes.

Normal flames.

Dragonflies aren't actually very fearful.

Many fire-based dragonflies are even capable of spitting phosphorus from their mouthparts, which can spontaneously ignite from the air, creating long tongues of fire to incinerate enemies.

It's just that the nether fire is not something that nether creatures can resist, and the dark source power inspired by the black diamond frightened them even more, and the terrifying source power fluctuations caused chaos in the rift, whether it was a predator or a prey, they were all frightened, and they fled as fast as they could in their lives, panicking.

The timid and weak flying insects are directly scared to death.

It rained down.

Don't talk about them.

Even the rock bears that followed the team roared restlessly for a while, looking everywhere for abyssal monsters that didn't exist.

Until Leo took the black diamond into his arms.

Source fluctuations disappear.

It breathed a sigh of relief in horror.

The obstacles to the path were cleared, and the Shadow Wolf followed the faint remnants of the human journey to a dilapidated stone bridge.

Leo walked slowly along the stone bridge through the underground valley.

Soon.

A new stone door was discovered.

Open the stone door, and there are several confusing forks in the passage.

Thankfully, there are the Shadow Wolves, whose keen sense of smell and natural tracking ability easily find the right way through them.

The rock bear also has a keen sense of smell, and he wanted to show it, but the two shadow wolves didn't give it any chance at all, and finally had to follow silently.

I took an unknown number of turns in the dark hole.

It seems endless.

Fortunately, Leo knows how to use the source force to create light ball lighting, so he has to go all the way so steadily, and he has to change to another ordinary novice rookie, who is black and winter along the way, and it is strange not to break his nose!

Leo carefully crosses the traps and traps, trying not to destroy the original landscape.

When the secret door opened, they were closed again.

I walked for more than an hour.

Finally.

A knife-cut oversized rock wall opening is in front of you.

Getting closer, you can see that the gap is deeply recessed into the other side of the cliff, forming a huge cave.

Looking out is the cliff, Leo carefully observed, identified the direction, and found that about forty degrees southeast of the cliff is his own way.

"Roar!"

The rock bear smelled the strong scent of the wyvern and roared uneasily.

The two shadow wolves also lowered their tails vigilantly, and hid half-crouched in the shadows at Leo's feet, ready to attack at any moment.
