Minutes and seconds passed.

A distance of a few hundred meters, Zhou Lu could have reached it in minutes.

And this time, it took him more than half an hour.

As long as it's safe to get there, it's well worth the extra time.

finally

He arrived at the designated position.

It is about 300 meters high from the Scorpion Fort below.

This location is at the dividing point between the upper and lower rock formations.

On the demarcation point is a looser shale.

It is this weak point of the rock mass that Zhou Lu wants to bomb.

Detonating this weak point could lead to an artificial landslide.

But it must be a deep detonation.

Exterior explosions don't work.

Zhou Lu's arrival at this position was just a prelude to the detonation plan.

He also had to dig a hole deep enough to stuff the big bag of explosives in his back.

And these steps, with Tang Ya and others have done detailed simulation and planning, and the preparation is also sufficient.

Zhou Lu first put the explosive bag on his back, slowly placed it in the cavity of the stone wall that was enough to support the weight, and camouflaged it with weeds.

Then he took out a large folded bag, hung it firmly around his waist, and then pulled out the fish intestine sword, and slowly cut the rock wall in a suitable position.

A fish intestine sword infused with soul power, digging loose shale is as easy as cutting cream.

However, when you want to cut it, it is difficult to make a sound without making a sound.

Zhou Lu slowly pierced the shale with a fish intestine sword, and then swiped straight to the side.

Cut two cross-sections, then two vertical sections.

In this case, a cuboid block was cut out, which he broke with his hand and placed in the prepared bag.

Fill it to a certain extent, and then find a place to pour out the rocks and place them.

All actions must be made silently and cannot be discovered by the black scorpion mercenaries below.

Zhou Lu is like a strange miner now, carefully digging rocks on the cliffs.

Whenever a bright light swept in, he quickly covered the hole with branches and weeds and hid his body.

So it's not a fast progress.

An hour passed.

Zhou Lu dug out a cave more than ten meters deep.

This cave is for Zhou Lu's body to climb into.

He was disgraced, but his eyes were full of excitement.

It's so exciting!

I've just put the explosives pack in the deepest part of the cavern, and it's finally done.

Zhou Lu exhaled softly.

Finally completed this difficult step.

Completing this is a big step towards success.

Next, it's time to detonate.

But you can't detonate it like this, your own people haven't stayed away yet.

When detonating, you must be in a safe position.

A timed explosive device solves this problem.

Zhou Lu was outside the small cave and pressed the remote control button.

There was a slight "beep" sound in the small cave.

A small red light flashed in the cavern.

10-minute countdown!

He was to leave the cliff in ten minutes and reach a safe position.

There was not much time, Zhou Lu did not hesitate, his speed increased to the limit, and he swam quickly on the cliff wall, skimming sideways.

Take off the weight and move much easier.

His body was as light as a feather, and he could leap far away with a random tap of his toes on the branches and leaves of the cliff.

It didn't take long for Zhou Lu to leave the range of the Scorpion Fort from the cliff horizontally and fall to the flat ground.

Only six minutes passed.

He didn't stop moving, he still ran as fast as he could, like a glimpse of light, and his figure was not visible to the naked eye.

He keeps an eye on the time on his watch and counts down to the blast.

At this point, the ten-minute countdown ends.

He stopped and looked back at the cliff.

Quiet night, starry sky.

Everything seems beautiful.

Suddenly, a blazing fire flashed from the cliff wall above the Scorpion Fortress.

The next second,

"Boom ......"

An explosion that resounded through the sky, like a thunderclap!

Instantly break the beauty and tranquility of the night.

The earth shook and the mountains shook, and countless birds and beasts in the mountains were startled.

The shaking of the ground this time was many times stronger and weaker than the mortar bombardment, and it is not an exaggeration to describe it as an earthquake.

Many sentries and patrolmen, standing or walking, fell.

The buildings inside the Scorpion Fort cracked, and a crack appeared in the sturdy and thick walls.

The momentum is terrifying!

The sentries had no idea what was happening, all they could tell was where the explosion had occurred, which was on the cliff face behind.

The sound of the explosion was so violent that their ears were ringing.

The sentinels all looked up at the cliffs.

Countless rocks were found falling from the cliff face.

suddenly

The black scorpion sentry screamed and was hoarse!

Realizing that it was under attack, they thought it was shelling, but did not understand why the shells had exploded on the cliff wall.

Since the cliffs would drop rocks, the Black Scorpion mercenaries had barely stayed in houses close to the cliffs.

Although the falling rocks were so loud that they crushed the building, they did not cause casualties and did not continue to explode.

It seems that everything is calm again.

The soldiers of the base camp of the ace army ran out of their tents one after another, picked up their weapons, and stared at the cliff with all their vigilance, their eyes full of doubt and shock.

In the face of an army of several thousand people, how could the other side dare to attack?

Is it looking for death?

Why don't the bombs blow people up and blow them up on the cliffs?

Why was the explosion so loud and what kind of weapon was used?

The falling rocks did not cause many casualties to the Black Scorpion mercenaries, and it had no effect on the Luzon Ace Army camp.

Therefore, the sentry of the ace army did not react immediately, and wanted to continue to observe for a few seconds and report after confirming it.

For Zhou Lu and Tang Ya, after the explosion, every second of the past seems to be the past year.

It's very exciting, but also extremely tormenting.

Tick tock...... Tick tock......

As the number of seconds increased, great disappointment rose in Zhou Lu's heart.

Is that all there is to it?

Hoping to blow up a corner of the cliff, it seems that only a few rocks will blow up, and it won't do much damage, let alone destroy it.

Too far from expectations.

The movement is quite large, but there is no use for eggs......

Really failed?

Perhaps the explosives were not powerful enough to cause significant damage to the main body of the support.

Whatever the reason, this is the only chance......

Tang Ya, Wen Yan and other Huaxia commandos also slipped through the faces of loss and regret, and were about to retract their gaze.

Suddenly!

The cliff that had just stopped seemed to shake again.

Immediately after, there was a rumbling sound inside the mountain peak.

It was like the sound of two heavy, hard rocks rubbing violently under heavy pressure.

The sound quickly changed from small to loud, getting louder and louder.

In a few breaths, it roared like rolling thunder.

Momentum!

The cliffs began to fall down again and again with rocks, dirt, branches, etc

It's not just the place where the explosion is falling, but the entire towering mountain is falling down, and the sound is getting worse, and the number of things falling is increasing by several geometrics.

And at this time,

The black scorpion mercenaries and ace soldiers in the room or tent all ran out, looking at the ever-changing cliff in confusion.

The searchlight is focused on the cliff face.

It soon became clear that the mountain was tilting.

And in the direction of inclination, there is the scorpion fort at the bottom of the peak.
