Gaining a tiny bit of weight every day, my weight is a billion tons.

When Su Ming climbed out of the pit, only one thought remained in his mind.

Again.

He stood up, dusted off the gravel and powder on his body, and turned to look at the granite block that had been pierced a hundred meters away.

Morning light streamed in through the round hole, its edges gleaming with a dark red, glassy sheen, while wisps of smoke curled upwards.

That's granite with a compressive strength of 100 tons.

He crashed right through it.

Su Ming clenched his fist, feeling something burning in his veins.

It wasn't pain, it was excitement.

The destructive power is not the problem; the issue lies in the control.

That last shot was a straight line. From the start to crashing through the granite and then carving out a hundred-meter-long ditch, it was like a bullet leaving the barrel, with a fixed direction that couldn't be deviated from. You couldn't stop it even if you wanted to.

But what if... you could veer slightly off course during the sprint?

You don't need to make sharp turns; even five or ten degrees is enough to avoid a pillar or go around an obstacle in battle.

The inertia of a one-ton body moving at high speed is indeed terrifying.

But he is now at the second-tier bronze level, and his muscle fibers have undergone mass reconstruction, making him far stronger than ordinary people.

In theory, as long as you use your waist and hips to generate power at the moment of sprinting, and tilt your center of gravity like a sprinter going through a curve, you should be able to make a fine adjustment.

Su Ming looked around the quarry.

His gaze swept past the scattered pile of rubble and locked onto a perfect test route.

Two hundred meters directly ahead, a three-meter-thick abandoned stone pillar stands alone, the remains of a supporting structure left over from the quarry.

About 500 meters behind the stone pillar is the natural mountain wall on the north side of the quarry, with a steep, grayish-white rock surface.

The plan is simple.

Ignite the fire, charge towards the stone pillar, and at the last moment, use your waist to dodge to the limit, bypass the stone pillar, and continue charging towards the mountain wall.

If successful, it means there's still hope for this skill.

Su Ming stretched his neck, and his joints cracked.

Stand firmly on your feet, squat slightly at the waist and legs, and lower your center of gravity.

The entire weight of one ton sank to the contact surface between the sole of the foot and the rock layer.

In my mind, the power path of the mass engine automatically appears: muscle fibers are compressed to the limit, joints are locked, and force is transmitted from the soles of the feet to the waist and hips, through the spine to the shoulders and back, all in one smooth motion.

This time, he added an extra instruction to himself: when approaching the stone pillar, turn his right foot outward by 15 degrees and twist his hip to the left to forcibly create a lateral force.

It is theoretically feasible.

Su Ming clenched his back teeth.

"ignition."

The rock beneath our feet cracked.

This is not an exaggeration, but a physical explosion. A circular crater half a meter deep reappeared, debris was ejected, and the sonic boom cloud behind them exploded into a white flower.

Su Ming's figure disappeared from the spot.

The air in the quarry was torn apart, leaving a visible vacuum trail.

The field of vision once again transformed into rapidly flowing blocks of color.

But this time he was mentally prepared, forcibly suppressing the surging dizziness and focusing all his attention on the rapidly enlarging stone pillar directly in front of him.

Two hundred meters.

150 meters.

One hundred meters.

The stone pillar grew closer and larger, until the three-meter-thick grayish-white rock pillar occupied most of the view.

just now!

Su Ming's brain issued the "turn" command.

Right foot turned outward! Hip twisted to the left! Weight shifted!

The instructions were precisely transmitted to every muscle fiber.

then……

Nothing happened.

No, that's not right.

Something has happened.

His right foot did indeed try to turn outward.

The hip did indeed try to twist to the left.

However, the inertia generated by multiplying a mass of one thousand kilograms by a speed close to the speed of sound is an astronomical figure.

His muscles were desperately trying to change direction, but inertia, according to the physical laws of the entire universe, was telling him no.

Sorry, Newton wouldn't allow it.

Su Ming's body was in an extremely strange posture.

The upper body did indeed show a slight tendency to lean to the left, about three degrees.

But the lower body was completely locked on the original straight trajectory, and the soles of the feet seemed to be welded to the rails.

Her whole body twisted into a slightly deformed pretzel shape.

And so, in a twisted and comical posture, it crashed straight into the stone pillar.

"Bang……!!"

The three-meter-thick stone pillar couldn't even withstand the pressure for half a second.

It broke apart and shattered directly in the middle, with the debris exploding to both sides, creating a cloud of gray-white dust that blotted out the sky.

Su Ming emerged from the shattered cloud of stones.

The speed did not decrease at all.

The mountain wall, 500 meters away, was approaching at a despairing speed in our field of vision.

That's too late.

There's simply not enough time.

He didn't even have time to mentally utter a complete swear word.

"boom……!!!!"

The entire quarry was shaking.

It's not a rhetorical device.

It's really shaking.

Su Ming slammed his fist into the mountainside in a posture that resembled the Chinese character "太" (tài).

The 1,000 kilograms of mass, combined with near-sonic kinetic energy, smashed a human-shaped crater more than two meters deep into the hard granite cliff face.

Cracks spread outwards from the center of the pit, densely covering the cliff face within a radius of several meters, like a spider web.

A large amount of rubble fell from a height, making a loud crackling sound as it hit the ground.

The smoke and dust cleared.

On the cliff face, there is a perfectly shaped, human-shaped pit.

Su Ming was embedded inside, his chest pressed against the rock wall, his limbs outstretched, his head turned to the side, and the left side of his face pressed tightly against the cold stone.

Not moving.

three seconds.

Five seconds.

"..."

ten seconds.

"cough."

He tried moving his left hand.

Not moving.

It was embedded too deep; the rock was stuck in his shoulder and elbow joints, as if it were filled with cement.

"……Hold."

Su Ming gritted his teeth and exerted his strength.

"Crunch..."

The left arm was pulled out of the rock face, along with a large piece of rubble.

Next is the right arm.

Then it's the left leg.

Right leg.

Finally, he bounced out of the cliff with a "pop" and landed on his buttocks on a pile of rubble.

Smoke and dust rose everywhere.

Su Ming sat there and looked down at himself.

Clothes? Gone.

Broken.

Only the waistband was still hanging there.

Body? Completely unharmed.

With a real mass of one ton and the bone density of second-order bronze, not even a red mark was left.

He looked up at the "太"-shaped human pit on the cliff face and remained silent for three seconds.

Then he started cursing.

"system!"

"The quality engine you sold me."

"Can't it turn?"

[The host's description is inaccurate. The Mass Engine provides extreme directional thrust, the direction of which is determined by the force vector at the moment of launch and cannot be changed once emitted.]

"So you can't turn."

【……Yes.】

"So you knew all along!" Su Ming almost punched the ground, but then thought better of it, afraid of punching a hole in the quarry and making the news tomorrow.

"Two thousand mass points! Two thousand! Two tons of pure mass! I scrimped and saved, poured all eight million of my Rock Robots into this, only to exchange it for a suicidal skill that can only move in a straight line?"

"Tell me, if the other person moves even half a step to the side during a fight, am I supposed to just bang my head against the wall and kill myself?"

[We suggest to the host...]

"Suggestions my foot! I want a refund! I want a refund! Have you even heard of the Consumer Rights Protection Law? The product is seriously inconsistent with the description; it's a seven-day no-questions-asked return policy!"

The system store does not support returns or exchanges.

Su Ming felt a lump in his throat.

"Good. Very good."

He stood up, patted the pebbles off his backside, and his mouth twitched.

Two thousand points of savings, gone in an instant.

That's it? That's it??

[The host's emotional fluctuations have been detected to be excessive. Additional information: The Mass Engine is a basic sequence designed for linear, extreme bursts of power. The host is currently at Tier 2, Bronze level; muscle fiber strength is insufficient to counteract the inertial lock-up under extreme speed conditions.]

Su Ming was stunned for a moment.

"What do you mean?"

[Once the host advances to Tier 3, Silver level, the system shop will automatically unlock the corresponding divine skill sequence for the Quality Engine...]

A dark gold icon appeared on the panel, with silver-white light patterns flowing around its edges.

Name: [Inertial Drift].

The description consists of only one line.

[During high-speed motion, the inertial vector is reconstructed using mass as an anchor point, enabling directional shifts and rapid trajectory changes.]

Su Ming stared at the line of text, his pupils contracting slightly.

Inertial drift...

It's not braking, it's not slowing down to turn, it's changing the direction of inertia directly while sprinting at full speed.

If the mass engine is like turning him into a cannonball, then inertial drift is like equipping that cannonball with a guidance system.

Straight-line artillery shells can be transformed into guided missiles.

Su Ming's lips twitched.

"...What the hell is inertial drift?"

"Next, are you going to give me an AE86 livery? And then the first shrimp catcher...?"

The system did not respond.

Su Ming rubbed his face, trying to suppress the surging irritation.

You can criticize as you please, but you can't stop thinking.

He sat down again, cross-legged, and began to review the events.

Quality Engine, Basic Version, Linear Directional Burst.

It starts at its peak, reaches full speed instantly, and its one-ton body can even pierce granite when it charges forward.

Its destructive power is undeniable, in fact, it's outrageous beyond belief.

The disadvantages are obvious: it cannot turn, brake, or change direction.

Once ignited, it becomes an uncontrollable shell.

But its tactical value is not zero.

In narrow terrain, corridors, tunnels, canyons, and city alleys, there's nowhere to run but to take the hit.

If a solid human body weighing one ton were to crash into you at the speed of sound, even someone wearing S-class full-body armor would be reduced to a photograph.

There's also the option of launching a surprise attack first.

Before the enemy could react, a straight-line charge was launched at close range, so fast that the enemy's nerve signals didn't even have time to be transmitted.

Su Ming's lips slowly curled up.

A skill that can kill in one hit.

It's not for a protracted war; it's for wiping the opponent off the board right at the start.

Considering the future inertial drift... Su Ming dared not indulge in any further fantasies.

If you keep thinking about it, you'll get carried away.

He stood up and looked at the mess around the quarry.

Two circular blast craters, a giant granite block that was pierced through, a shattered stone pillar, and a cliff face with a human-shaped crater embedded in it.

In addition, there are two deep ditches, each 100 meters long.

The visuals are on par with a tactical nuclear bomb.

Su Ming thought for a moment, then glanced again at the "太"-shaped indentation on the cliff face.

"You have to check if the venue is valuable before you start a fight," he muttered. "If this happened in the city..."

He couldn't afford to lose money even if he sold his ass.

Forget it, that's not the most urgent thing right now.

Silver level unlocks inertial drift.

The process of transforming bronze into silver requires a real mass of 10,000 kilograms.

He now weighs a little over 1,000 kilograms, with a weight balance of 277.2.

It's not even close.

But Shen Hongyuan has already agreed to grant passage to the heavy goods area today.

Heavy object area.

Destroyed armor plates, mech wreckage, military-grade alloy components...

Those weren't tiny parts or screws in the corner of the sorting area; they were tons and tons of high-purity military-grade metal.

He could eat a piece of food all day long in the sorting area and that would be enough for him.

Su Ming turned around and walked towards the exit of the quarry.

The rising sun had just crossed the horizon, casting a long shadow of him.

In the distance, the towering chimneys and mountains of steel scrap at the Xinghuo Waste Treatment Plant gleamed with a cold metallic luster in the morning light.

Su Ming licked his lips.

Today, we thoroughly explored the heavy objects section.
