The Glory of Noxus.

[Type MK6: Earth-Drilling Robot]

The black curtain slid down, and the Hextech robot developed by Professor Heimerdinger appeared in front of everyone.

The whole body of the earth-drilling robot is silver, with a metallic luster. It is both sturdy and full of a cold sense of technology.

At the front of the machine is a huge silver drill bit with threads, sharp and hard, as if it can penetrate any obstacle.

Behind the drill bit is the part where the boom and the frame are connected.

This is the most important part of the earth-drilling robot, responsible for providing strong power and stability.

Finally, there is the metal body of the earth-penetrating robot, which is about three people tall, huge and heavy.

There were subtle stone wall marks left on the metal body when passing through the safe passage.

From the appearance of the robot in front of him, it can be seen that Piltover went all out for this operation in Stillwater Prison.

Buzz!Buzz!

Wearing a blue uniform and gold-rimmed glasses, the Hextech inventor walked up to the earth-drilling robot and input commands skillfully.

Following his operation, the earth-penetrating robot started slowly, made a low sound, and drove to the location of Huo Jixing.

Whoops! Whoops!

The Hex core roared, the silver drill rotated, and gusts of wind appeared.

Until the speed reached its extreme, the hurricane swept through the low prison, causing flying sand and rocks.

The members of the police team stepped aside one after another, away from the sand and drills.

They closely watched the movements of the earth-penetrating robot, hoping that it would successfully find the location of the hidden experimental base.

Caitlin and Camille also paid attention, waiting for the final result.

Click! Click! Click!

The ground-drilling robot continued to roar, cutting into the specially treated hard ground.

Fine stones fell like raindrops, covering the surrounding ground.

Just a moment.

A hole appeared on the ground, and more and more rocks and dust were piled up.

But the hole is getting bigger, but the desired experimental base location has not yet been found.

Huo Jixing looked calm and looked at the earth-drilling robot in front of him, marveling at the changes brought about by Hex Technology.

Caitlin was a little anxious.

After being entrusted by Jace, she knew the importance of this operation and the urgency of time.

Looking at the position of the earth-penetrating robot, she became somewhat suspicious of Huo Jixing.

Perhaps the location of the experimental base is not down there at all.

The ground-drilling robot was running at full speed, and the fine gravel and dust it brought up felt a little damp.

Buzz!

Just when Caitlin was suspicious, the earth-drilling robot suddenly made a sharp sound.

Immediately afterwards, the drill bit seemed to have touched something hard, making a metallic impact sound.

Caitlin's expression changed and she immediately walked to the side of the earth-boring robot.

The Hextech inventor shut down the earth-drilling robot at the right time, causing it to stop where it was.

Through the hole cut by the drill, a thick layer of metal sandwich panels can be seen.

Camille nodded slightly, signaling Caitlin to come back first, and then asked the Hextech inventor to continue starting the earth-drilling robot.

As the drill bit rotated, vibrations came from the underground. The metal sandwich panel could no longer hold on and quickly shattered, revealing a hidden dark passage.

"I'll go down first."

Camille walked to the entrance of the cave and spoke softly to Huo Jixing and Caitlin.

Immediately, the Hex device glowing blue on her thigh fired a hook that could be attached to the terrain.

The steel hook quickly shot to the bottom of the hole and attached tightly to the solid wall.

Camille grabbed the hook, pulled it gently, and slid down lightly.

After a while.

Camille's calm voice came.

"It's safe, you can come down."

Hearing Camille's words, Huo Jixing and Caitlin looked at each other, nodded slowly, and prepared to enter the cave entrance.

In the dark passage.

There are lights on the dark top, like stars dotting the night sky, dispelling the surrounding darkness.

The space inside the passage is surprisingly wide, allowing four or five people to walk side by side.

After landing.

Huo Jixing was looking around, waiting for Urgot to come down.

It was because Urgot was too big, and the hole was dug by the earth-boring robot, which delayed it for a while.

When Urgot came down, Caitlin and Camille walked towards him.

"We have to be careful."

Camille looked at the passage extending to an unknown place, feeling a little uneasy.

"This should be the secret experimental base of the forces behind the Eye of Zaun. The danger is essential."

Huo Jixing nodded and agreed.

He looked up at the entrance of the cave and saw many members of the police team staying on the ground.

On the one hand, it is to leave a safe escape route and ensure that you can leave quickly when encountering danger.

On the other hand, it also protects the earth-penetrating robot from being destroyed when left unattended.

Dim yellow lights flickered in the passage.

The group stayed quiet and walked along the smooth and thick road.

In the corners of the metal walls on both sides, you can still see moss and mold intertwined.

The figures of the people also cast long shadows under the light, which gradually changed with their steps.

Huo Jixing was always alert to the movements around him, and his pupils were filled with red-golden light.

He saw many clouds rising, but they were far away and no longer nearby.

At the same time, he also discovered that the metal walls in the passage had been specially treated.

The spiritual power cannot extend too far, up to about ten meters.

Faintly, Huo Jixing heard the subtle sound of water flowing.

Then he immediately thought of the wet rocks and dust brought up by the previous earth-boring robot.

"This passage is built at the bottom of the Piart River." Huo Jixing sighed secretly.

"No, that's not right."

He rejected his inner thoughts.

"To be precise, it should be that this secret experimental base directly penetrates the bottom of Stillwater Prison and goes deep into the river bottom."

"And such a huge project was actually hidden from the Piltover Council. It seems that there are people inside helping to cover it up."

Accompany them in depth.

Camille seemed to be aware of this, as a cold look appeared in her eyes.

With her keen sense, she observed that the air in the passage was somewhat humid, and she also saw water stains on the metal walls on both sides.

"Piart River!"

After passing a corner of the passage, everyone's vision suddenly became clear.

In front of the group of people, four almost identical passages appeared.

Thick dark gray iron gates were erected in front of each passage, blocking their way forward.

Looking carefully, the surface of the dark gray iron door is extremely smooth, with no trace left.

Behind it, there was a faint sound of gears running.
