In a dark tunnel.

Yun Mu commanded the No. 2 burrower rat to gradually get closer to the hole and try to start penetrating.

True, he did not go directly into the burrow.

The following may be where the enemy's base camp is located, Yun Mu is not stupid, how can he take the right path?

He based his burrowing rat's acumen for the underground.

A new tunnel was dug next to it, trying to connect the two in the middle and then blend in with it.

Knocked on the tunnel and the rock wall over there.

Yun Mu waved his hand to let the No. 1 burrowing rat step forward, and the distance should only be about one meter away now.

Creak!!

In the excited cry of the burrowing rats, the rock wall was dug through little by little, revealing some light.

Boom!

As large rocks fall, Digger No. 3 is the first to emerge from the tunnel.

After it was in no danger when it probed, Yun Mu took the phoenix butterfly and they walked out of the burrow.

into the eye.

The surrounding scenery is very different from what you imagined.

Dozens of glazed-eyed electric dragons illuminated the vast underground space as bright as day.

This space is the size of a playground.

Instead of being bloody, there was a leafy fruit tree growing in the center.

Fruit tree?

Just when Yun Mu was puzzled.

An electric dragon surrounded by blood-colored thunder and lightning appeared next to the silver-white cylindrical machine connected to the fruit tree.

Holding the positive and negative buttons next to the machine with both claws, the electric dragon slowly injected the blood-colored thunder and lightning on its body.

The injection of lightning causes the machine to start up.

The silvery-white column began to hum, and its transparent hose approaching the trees began to appear a turquoise liquid.

"What kind of tree fruit is that?"

Because of the injection of liquid, the fruit tree emitted a faint light, which also allowed Yun Mu to see the tree fruit on it.

"How is this shape so familiar?"

Yun Mu felt as if he had seen it in a book, and after thinking about it seriously, he shouted loudly.

Azure Fruit!

It is the legendary fruit of life!

In mythology, the Azure Fruit is also a holy fruit, which allows pet beasts to freely control the power of evolution.

This fruit only exists in legends and has not been seen since ancient times, so it has always been regarded as a bizarre myth and legend.

After a few more glances at the tree, Yun Mu realized that the tree fruit seemed to be incomplete, as if the other half was naturally missing.

However, this is also a great opportunity!

"Anchovy butterfly, pick it off quickly, it's really not good, you can eat it yourself."

Yun Mu hurriedly asked the phoenix butterfly to pick the fruit on the tree, after all, the opportunity must not be lost, and the time will not come.

The butterfly eventually eats the fruit.

Because Yun Mu found that once the fruit leaves the fruit tree, it will shatter into scattered green points of light.

Then he proposed that the phoenix butterfly be hung on the tree, and swallowed a few of the tree fruits raw.

Buzzing!!

Yun Mu felt a buzzing sound suddenly ringing in his ears, noisy and harsh, making him a little dizzy.

Where does the noise come from?

Looking around, except for the electric dragon who was stunned in place, it was a group of people.

He didn't care, and continued to ask about the different feelings of the phoenix butterfly after eating the tree fruit.

Until a strong wind blows.

Yun Mu realized that something was wrong, turned around and looked back, and saw a huge black shadow.

This black shadow is a giant sword shadow worm!

The slender scythe, more than a meter high, is huge, as if every flap carries the wings of a hurricane.

[Pet Beast Name]: Blade Shadow Worm

[Pet Beast Race]: Insects, Flying Department

[Pet Beast Level]: Overlord level

[Pet Beast Skills]: Cross Slash, Slash, Tempering, Iron Armor Defense

See the three words overlord.

Yun Mu's pupils shrank, knowing that this time was really dangerous.

Biting the tip of his tongue hard, he forced himself to calm down.

Command the three burrowers to dig a hole next to them and make the final preparations for escape.

At this time, the giant blade shadow insect finally smashed to the ground.

Its appearance is very similar to the one that the phoenix tail butterfly killed last time, but its power is several times stronger than that one.

After falling to the ground.

The giant blade insect first looked at the tree fruit that it had been so well protecting.

Then he discovered the fact that he was furious, and all the fruit was eaten.

Looking at the phoenix butterfly with a fierce gaze, the giant knife shadow insect noticed the residual smell on her body.

Not only does it have the taste of the tree fruit that it carefully protects, but it also has the taste of its own offspring.

The giant blade shadow insect roared in the sky.

Its eyes had turned blood-red, and the forelimbs of the massive scythe trembled as it slashed down.

The phoenix butterfly does not dodge or dodge, but a scale on its body that is easy to be of other colors glows slightly.

The scales grew violently, and cracks appeared until they finally shattered.

Dots of silver light and dust appeared, forming a phantom behind the phoenix butterfly.

Facing the sharp giant blade in front of him, a thick silent light wave condensed from the phantom's mouth.

Rumble!

For example, two comets and meteors collided, and a huge gap in the ground burst out.

Both sides retreated half a step back at the same time, evenly matched.

However, for the overlord-level attack, Yun Mu only has one move.

Seizing the opportunity, he held the phoenix butterfly in his arms and simply burrowed into the hole.

Bye-bye, you're not fighting!

The giant Blade Shadow Worm also noticed that these ants, who had been provoking them for a long time, were about to escape from their burrows.

Its blade-like forelimbs are crossed and erected.

Slashing down towards the hole, the Crosslight Slash condensed from the blade and fired.

Cross Slash!

Exuding a formidable slash of light, it cleaved open the hole with a thunderous force, and then slowly but surely flew inside.

The rock at the entrance of the cave was split, the pillars became crumbling, and the ground began to collapse.

Yun Mu threw the cotton cloud backwards, and pounced forward, pressing the pet beast in front of him under him.

A cotton cloud the size of a finger's belly.

At first, it glows with seven colors, then it begins to replicate itself and grows larger until it fills the entire space.

Boom! Boom!

The crosslight slash hits the cotton cloud like a bouncy ball, and as soon as it slashes the dent, it returns the same way with greater force.

Ahead.

The three burrowers were almost sucking their strength, nibbling on the dirt and digging up the newest passage with all their might.

Behind him, the giant Blade Shadow Worm began to dig holes.

Yun Mu asked Xiao Tieshi to electrify the three burrowing rats, so that they could regain their composure, don't dig holes in a straight line, and pay attention to getting rid of the giant knife shadow worm behind them.

Cracking sound!

The three burrowing rats were slightly numb by the electricity, shook their heads, calmed down a little in a panic, re-measured the direction, and continued to dig upwards.

It was not until it returned to the ground that it rested for a while.

Leaning sideways to listen to the movement underground, the roar of the giant Blade Shadow Insect was already inaudible.

Getting up and tidying up, Yun Mu took out the nutrition cube and distributed it to the three burrowing rats.

He wants to report this news to Sister Qianqiu as soon as possible, there must be something wrong with this ruin, there is actually an overlord-level pet beast in it, maybe it is related to the truth they explored.
