My whole family was brutally murdered? I awakened the thug system and went on a killing spree.

Qin Meng looked up towards the south.

"Go and proctor the exam in the second exam room."

The commander of the Nanling defense line is named Ye Shuang. He was originally the deputy captain of the Southern Rapid Deployment Team and studied civil engineering before the apocalypse.

This major is in high demand in the post-apocalyptic world.

While others would simply yell "It's collapsed!" when faced with ruins, Ye Shuang could calculate the load-bearing capacity while yelling, and even casually curse the construction company for being heartless.

After taking over the Nanling defense line, she carved out a three-layered ring-shaped fortress from the mountain and built a high-dimensional crystal energy storage facility underground.

Logically speaking, this place should be able to withstand both beast tides and small warship debris.

But the vanguard of the royal court deliberately didn't attack from above.

It burrows directly into the ground.

Ye Shuang stood in the underground command room, watching the red dots on the geological map go down, her face so dark it could be used to paint a wall.

The adjutant, sweating profusely, cried out, "Captain Ye, it's only 800 meters from the energy storage facility!"

Ye Shuang retorted, "What are you yelling about for 800 meters? If it were only 8 meters, would you be writing your will first?"

The adjutant felt wronged: "I even prepared a template for my will."

Ye Shuang kicked him: "Put it away, stay alive first."

The Nanling Fort did fire.

Upon landing, the lander immediately unfolds its outer shell, transforming into a giant drilling beetle covered in shock-absorbing armor.

When the artillery fires on the ground, it only shakes off some of the mountain's surface; it can't even touch the enemy's armor.

Ground troops tried to intercept them, but the drilling beetle released a high-temperature mudflow that completely blocked the passage.

Its motive is clear.

The Nanling Energy Storage Facility supplies 37 auxiliary arrays in the south. If it were destroyed, a large part of the fire control network in the southern hemisphere would be missing.

The Reaper mothership doesn't need to defeat Qin Meng in one go; as long as it causes each defense line to bleed out, it can eventually turn the Earth into a sieve.

Ye Shuang understood this, which was why she was even angrier.

She grabbed the communicator and yelled, "Has Qin Meng arrived yet? If he doesn't come soon, I'm taking some men and crawling through the ventilation ducts to fight him!"

Hu Biao's voice came through the communicator: "Team Leader Ye, I'm an expert on ventilation ducts, but don't follow my example. I got stuck in one of those situations back in the day."

Ye Shuang angrily said, "Hu Biao, if you come to Nanling, I'll weld the ventilation pipes shut."

Hu Biao immediately fell silent.

The next second, gravity suddenly sank over the Nanling Mountains.

Qin Meng fell from the sky and landed on the top of the mountain, the rock beneath his feet making a muffled sound.

On Ye Shuang's screen, Qin Meng's life signal jumped directly to the red core area.

She immediately connected to the channel: "Qin Meng, the enemy is 400 meters underground. Its outer shell can disperse shock waves, and a normal attack will collapse the mountain."

Qin Meng looked at the energy trajectory below the mountain range and said, "Understood, we can't smash it."

Ye Shuang's tone became even more urgent: "We can't delay any longer, it's cutting through the energy storage's isolation layer!"

Qin Meng raised his hand and pressed it to the ground.

The black hole engine scanned the underground structure, laying out the mountains, tunnels, energy storage facilities, and enemy drilling routes in his mind.

Drilling beetles are indeed troublesome.

It locks its body and the surrounding rock layers together, and every time it is subjected to force, the impact is transmitted to the entire mountain.

Hitting it is like hitting a mountain.

The mountain collapsed, and the Nanling defense line was destroyed.

After remotely connecting, Chu Feng said, "This thing belongs to the Royal Court's engineering corps. It's specifically designed to dismantle underground facilities. It's not afraid of head-on collisions, but it's afraid of internal chain breaks."

Lao Lu added, "It has six drilling nodes; if they all get stuck at the same time, the body will stop rotating."

Ye Shuang understood, but was even more troubled: "Simultaneously targeting six points? We can't even pinpoint its angle."

Qin Meng said, "I can touch it."

He didn't go down.

He stood on the mountaintop and let the gravitational field seep into the strata.

That wasn't about violently creating a hole; it was about adjusting the direction of gravity within the mountain in layers.

The drilling beetle was spinning wildly underground when it suddenly found that the rock layer in front of it had become slippery.

Its drill bit was clearly inserted into the rock, but it couldn't get any leverage, and its whole body began to slip in place.

Ye Shuang stared in surprise as the red dot on the geological map suddenly began to spin erratically: "Is it lost?"

Hu Biao interjected on Jiangcheng Channel: "No, it's been turned into an underground spinning top by Lao Qin."

The drilling beetle realized the anomaly and immediately released a stream of hot mud in an attempt to melt through the gravitational disturbance layer.

Qin Meng twitched his finger.

Six gravity needles pierced through the rock strata and anchored to its six drilling nodes.

This process is difficult.

High temperatures, high pressures, and complex mineral layers underground can all interfere with accuracy; even a slight deviation can cause fissures in the mountain.

Qin Meng's black hole engine was running at a high frequency, and hot air was billowing from his forehead.

Ye Shuang didn't dare to urge them while standing in front of the screen.

She knew this job was much harder than smashing the enemy.

Smashing the enemy is a warrior's pleasure problem, protecting the mountain before capturing the enemy is an engineering problem, and engineering problems are always more immoral than warrior's pleasure problems.

The drilling beetle emitted a sharp vibration, trying to shatter the gravity needle.

The walls of the Nanling underground passage began to crumble, and the crystal tanks in the energy storage facility glowed a dangerous red light.

The adjutant's voice trembled: "Captain Ye, the pressure at the energy storage facility is increasing!"

Ye Shuang pushed him away and sat down at the control panel herself: "Open the No. 3 pressure relief shaft and channel the excess energy into the abandoned mine shaft."

The adjutant was shocked: "There's still frozen meat in there that we haven't finished eating!"

Ye Shuang retorted angrily, "Is your life more important, or frozen meat?"

The adjutant said with tears in his eyes, "My reason tells me that life is more important."

Ye Shuang roared, "Then execute it!"

The No. 3 pressure relief well was opened, and high-dimensional crystal energy was guided into the abandoned mine shaft, bursting out a burst of blue light.

Taking advantage of the pressure change, the drilling beetle suddenly launched a hidden tail drill, piercing straight into the bottom plate of the energy storage tank.

Qin Meng's eyes turned cold.

This thing is not only a destroyer, but it can also induce gaps in the defenses when they try to save themselves.

It was designed to be insidious.

Qin Meng raised his hand and made a grasping motion, directly compressing the space around the tail drill into a two-dimensional thin surface.

The tail drill instantly lost thickness and got stuck in the rock layer, unable to move.

The drilling beetle struggled frantically as its exoskeleton began to charge.

Chu Feng shouted, "Watch out! It's going to self-destruct! Its engineers will blow up the target area after they're captured!"

Qin Meng laughed: "I've been waiting for this."

He used a gravitational field to envelop the drilling beetle's shell, preventing it from exploding.

Then, he temporarily closed all the tiny cracks inside the mountain, creating a sealed container for the enemy with nowhere to release pressure.

The drilling beetle's energy kept rising, but it couldn't find an outlet.

Ye Shuang watched the data soar, her scalp tingling: "Qin Meng, don't let it explode like a firecracker!"

Qin Meng said, "Don't worry, I left it an opening."

He reached up and pulled upwards.

A narrow vertical shaft split open in the ground at the top of the mountain, leading precisely to the top of the drilling beetle's head.

The next moment, Qin Meng forcibly pulled the entire drilling beetle out of the ground.

It burst out of the mountain carrying lava and mud, its massive body still spinning at high speed.

Watching the live stream remotely, Hu Biao exclaimed in surprise, "Wow, Lao Qin caught a hard-shelled turtle!"

Ye Shuang was also dumbfounded: "This thing can really be pulled out?"

Qin Meng pressed down on the drilling beetle with one hand and smashed it onto the open ground at the top of the mountain.

The drilling beetle tried to self-destruct, and its core glowed red.
