The Earth Dragon is digging rapidly into the ground.

One kilometer, two kilometers, three kilometers......

An Wen watched the numbers on the odometer keep changing, and soon jumped to double digits.

Goo!

Swallowed.

At this time, An Wen's calves began to tremble.

"You won't dig into the core."

Even if the angle of digging down is only 34 degrees, if you dig 12 kilometers down at this angle, it is very deep.

Click!

An Wen pulled down the lever and made the Earth Dragon stop advancing.

At the same time, control the weapon system to stop the attack and retract the armor.

He was going to turn on the detection device, check what was going on underground, and then make a decision.

It feels a bit silly to keep digging like this.

Bang bang bang......

The sonar detector activates, and the inflatable hammers on both sides of the earth dragon hit the mine.

Then, a sound wave collection device like a stethoscope extends from the four directions of up, down, left and right, and clings to the rock wall of the mine.

The sound waves transmitted from the rock wall, amplified by the sound wave harvesting equipment, are placed on very precise machinery, and finally hit by countless levers on the precision machinery under several very thin metal plates, so that the fine metal powder on these metal plates is constantly polymerized and discrete.

A pile of tiny metal powders quickly drew a rudimentary map of the vein's movements.

An Wen looked at the graphics on several pieces of metal film and kept thinking.

"It's really unpleasant to have no 3D imaging, and you have to think about it yourself."

After thinking about it for a long time, An Wen finally constructed an even more rudimentary underground topographic map in his mind through a few rudimentary maps.

Through this underground map, he really discovered a strange situation.

"According to the instructions, the probe has a radius of 5 kilometers, but at the position of 3 kilometers ahead, there is a blank.

Normally, there is a gap because of the discovery of underground cavities and underground rivers, but this island does not even have underground water, let alone underground rivers.

And it's not just a picture with a large blank area, the sound wave feedback of the upper and lower four layers all gives a blank display, which represents a height of 4 kilometers.

Whose underground river can be 4 kilometers high, and the underground fault is about the same, there is definitely a problem there. ”

After an avan muttered to himself for a moment, he retracted the sonic harvesting device and pushed down the joystick, allowing the Earth Dragon to move on.

He was going to see what was going on there.

What if it's a new underground space?

Doesn't that mean that he has a boss to fight again.

Controlling the speed of the earth dragon, An Wen gradually approached even the empty area.

2 km ...... 1 km ...... 500 m ...... 200 m ...... 50 m ...... 10 m ...... 1 meter

Buzz Buzz......

After piercing the last layer of ore, the head of the Earth Dragon directly began to idle.

An Wen ignored this, he looked up at the periscope directly in front of him, wanting to know what was going on in front of him.

"There is light? Underground forests? What's that? ”

Originally, An Wen thought that there was no surprise ahead, after all, there was only one kerosene lamp in front of the knife head, which was not very bright.

To his surprise, the picture seen through the periscope was surprisingly clear.

It's like having the sun overhead.

Moreover, what appeared in front of him was not an underground mine, but a forest.

Many of the trees are known to Anwen and are of the species owned by the island, and he has cut down a lot of them.

In addition to the trees, he saw that the ground was covered with bright red plants with saffron-like tentacles slightly curled.

Not only do these plants cover the ground, but they also sway like aquatic plants at the bottom of the sea.

This kind of surprising scene of painting style made An Wen a little confused.

Roar!

At this time, a monster roar was heard.

Soon, a group of huge monsters appeared in An Wen's sight.

"it!"

After seeing this group of monsters, An Wen screamed.

He was familiar with these monsters, they were the monsters that attacked the city every night.

Even if the monsters in front of them were of different sizes, no matter how much they pretended to be their tails, the meteor hammer betrayed them.

When they ran in front of the earth dragon, the tails of these monsters cocked.

"You want to hammer me too?"

Seeing this, An Wen pursed his lips and pushed down the joystick, causing the earth dragon to retreat one meter back.

Just retract the cutter head into the seam.

It's not cowardice, it's called strategic contraction defense.

After all, these monsters were able to tremble the five-meter-thick, steel-clad city wall, and he didn't think that the earth dragon could withstand the attack of this group of monsters.

Touch!

Touch!

Touch!

As soon as he retracted the head of the knife, An Wen heard a loud noise in his ears, and he trembled as he sat in the earth dragon.

This group of iron Hanhan directly hammered the meteor hammer of the tail towards the ore layer.

Among them, there was a monster that flung its tail at the head of the earth dragon's knife.

Convex (艹)

An Wen was hammered, very hot, and directly opened the weapon launch port in front of the knife head.

"Come, let you taste the justice of the 380 mm caliber."

He didn't have to aim, anyway, a bunch of monsters were diagonally below, right in front of the muzzle.

Click!

The shell is loaded.

An Wen directly pulled down the lever to open fire.

Rumble!

There was a loud bang, and An Wen's ears were buzzing.

Below, the three monsters that were hit head-on were instantly emptied of their health bars and exploded on the spot.

The monsters that were affected around them, although they were not seconded, were also missing arms and legs, and most of their blood bars were lost.

"Come on, hurt each other."

Although the skull hurt from the roar of the artillery, the power of such an attack is still very cool.

Big is beautiful, more is good, caliber is justice, and range is truth.

"Something seems wrong."

Through the periscope, An Wen found that the ground that was attacked by artillery fire had already launched changes.

The red stamens that were originally swaying in the wind were all closed at this time and were clinging to the ground.

The ground gradually solidified, turning into a protective layer similar to that formed by scales and bone tissue.

Next, the protective layer opens, revealing a bud-like spherical tissue.

In the next second, red silk threads suddenly erupted from the bud tissue.

"This is a fungus blanket, right? How can you still spit spider silk? ”

Although the periscope can't observe the situation of the knife head, An Wen can be sure that there should be a fungus blanket on the ground.

He couldn't figure out why the fungus blanket could spit out these red silk threads.

Soon, the threads stick to the cutter head.

"Think about it too much, this bit of spider silk wants to entangle the knife head."

Anwen pulls down the lever and lets the cutter head start rotating.

Puff puff......

Although the cutter head began to rotate, silk threads continued to erupt underneath.

Then, An Wen saw that the value of the pressure gauge began to slowly increase.

"The toughness of this silk thread is a bit awesome."

An Wen immediately changed the gear to the first gear, and instead of pursuing speed, he began to increase the torque of the cutter head.

At the same time, he opened all the weapon launches on the head of the knife.

After the firing of 6 machine guns, after the firing of four 130 guns and after the firing of one 380 main guns.

"Offense is the best defense."

Boom Boom Boom ......

Da Da Da ......

An Wen covered his ears and controlled the earth dragon to fire with all his might.
