130: Chapter 130, Physics Lesson 2: On the Principle of Resonance and How to Break a Tortoise Shell

Titan Arena, F Zone Preparation Room.

The previous 'monster mukbang' had plunged the entire arena into a bizarre frenzy. Although most of the audience was still grumbling and cursing, calling it barbaric, the viewership ratings had honestly skyrocketed to number one across the entire Alliance. After all, who wouldn't want to watch a black monster with a mouth, drooling, and chewing high-tech mechs like potato chips?

Inside the preparation room, Lei Wanjun (Head of the Physics Department) was busy bustling around xingtian no. 1. 'Little Black, that last bite was too fierce; you chipped two teeth.' Lei Wanjun, wielding a welding torch (which was actually a Three Flames True Fire Projector), was performing 'dental work' on the mech's abyssal maw. 'Remember next time, when eating high-hardness alloys like that, use 'Corrosive Acid' to soften them first. It's table manners, and it also protects your teeth.'

Inside the cockpit, Little Black, chewing gum, replied with a look of indifference, 'Got it. It's mainly because that Aurora mech's texture was too crispy, like a soda cracker. I couldn't help myself.'

In the corner, the Scrap Iron Clan's T-9 robot was holding a personal terminal, its electronic eyes flashing red wildly, so excited that all its parts were rattling. 'We're... we're rich!' 'I bet on us to win on the side market, odds 100 to 1! Now we have fifty million star credits in our account!' T-9 felt its processor was about to overheat. It had never seen so much money in its life and was already planning whether to upgrade to a pure gold oil filter for itself.

'Stay calm,' Li Mo said, sitting on the sofa, holding a cup of 'Magma Hot Latte' freshly brought from the abyss, blowing on the foam. 'That amount is only enough to buy a few screws. Our target is that 'titan core.''

Just then, a piercing alert tone sounded over the arena broadcast. 【Please, Team 404, enter the arena!】 【Second Round Opponent: The Defensive Great Master from the Gravity Star System — the Heavy Tank Clan Team!】 【Mech Model: Xuanwu-V Type!】

...

On the arena platform.

When xingtian no. 1's pitch-black, bloated figure appeared again, the boos from the spectator stands noticeably diminished, replaced by a sense of morbid curiosity and anticipation. On the opposite side of the platform, a colossal mech resembling a mobile fortress had already been waiting. This 'Xuanwu-V' mech had no legs; its base consisted of heavy treads, its upper body was hemispherical, and its entire body was forged from the Universe's hardest 'Neutron Star Alloy'. It had no fancy weapons, only an almost body-covering, thick yellow-glowing **【Gravity Shield】**.

'Heavy Tank Clan, defense invincible!' a muffled broadcast came from inside the Heavy Tank mech. 'Your kind of savage biting is useless against us! Our shield can even withstand planetary impacts!'

The match-starting whistle blew. *Hum—!* The Xuanwu mech immediately activated 'Absolute Defense Mode' right on the spot. That layer of yellow Gravity Shield instantly solidified, turning into a golden, translucent giant egg, firmly encasing the mech inside. It had no intention of attacking at all; it just wanted to wear its opponent out.

Inside the cockpit, Little Black tried controlling xingtian no. 1 to charge forward, swinging its massive black fist to tentatively punch the shield. *BANG—!!!* A tremendous sound. xingtian no. 1's fist was violently repelled. The golden giant egg didn't budge an inch, not even a ripple. Instead, Little Black felt a numbing sensation run up its arm.

'Bite it!' Butcher Xiao shouted over the comms channel. 'I don't believe there's anything in this world our Tianhe Peak bite can't chew through!'

Little Black controlled the mech to open its giant maw and bite down hard on the light-egg. *CRACK!* This time, even without Lei Wanjun checking, it was clear the teeth were definitely all shattered. The shield wasn't just hard; its surface was extremely smooth, offering no point of leverage. xingtian no. 1 was like a dog trying to bite open a stainless steel ball, finding no way to get a grip.

'Hahaha! Give up!' the Heavy Tank Clan pilot mocked. 'This is a Gravity Rule Shield! Unless you can deliver energy exceeding the shield's load limit—equivalent to the power of a supernova explosion—don't even think about breaking through!'

Inside the preparation area. Butcher Xiao grew anxious: 'Dean, this turtle shell is too hard! Should I bring the 'Myriad Laws Return to One Cannon' (Tianhe Peak main cannon) over to blast it once?'

'No need to use a sledgehammer to crack a nut,' Li Mo said, pushing up his glasses, his gaze calm as he watched the smug golden egg on the platform. He picked up the walkie-talkie and connected to Lei Wanjun's channel. 'Director Lei, it's time for the students' second Physics lesson.'

'The topic is: 《How fragile an object becomes when its natural frequency is captured by an external force.》' 'In simple terms, it's—resonance.'

Lei Wanjun, down by the platform, eyes lit up. 'Understood!' 'No need for brute force, just... find the right pitch!'

Lei Wanjun quickly input a string of commands into the console, remotely modifying the operating parameters of the six 'Flying Sword Wings' on xingtian no. 1's back. 【Command Update: Activate Vibration Mode.】 【Frequency Scan: Capturing target shield's natural frequency...】 【Frequency Locked: 3452 Hz.】

On the arena platform.

xingtian no. 1, which had been circling the golden egg, suddenly stopped. It ceased attacking and slowly extended the six mechanical tentacles (Flying Swords) on its back. These six Flying Swords did not stab toward the enemy but began vibrating at high frequency in the air, like tuning forks.

*Hum... hum... hum...* At first, the sound was very faint, just a low hum. But as the frequency was continuously adjusted, the sound became extremely shrill, and even the air began to show visible ripples.

The Heavy Tank Clan pilot hiding inside the shield initially sneered: 'What? Can't bite it, so you start making noise? Trying to deafen me?' But a few seconds later, his expression changed. He discovered that his supposedly indestructible 'Gravity Shield' was actually starting to... vibrate along with this sound. And the amplitude of the vibration was getting larger and larger.

'Wh-what's going on?!' 'Shield stability dropping! 90%... 70%... 50%!' 'Alert! Structural resonance detected! Shield approaching disintegration!'

'Increase power!' Li Mo's voice echoed in Little Black's mind. 'Just like shattering a glass with a high note. Give it the final blow—Tianhe Peak Lion's Roar!'

*ROAR—!!!!* xingtian no. 1's abyssal maw suddenly gaped wide. This time, it didn't spew a shockwave, but a precisely frequency-calculated beam of sound waves. This sound wave perfectly superimposed with the vibration frequency of the six Flying Swords, forming a terrifying 'Resonance Storm'.

*CRACK—!!!*

In that instant, the golden giant egg, which boasted the ability to withstand planetary impacts, emitted a crisp shattering sound. Just like a crystal glass shattered by a soprano's voice. It wasn't broken by force; it 'shook' itself apart. Countless golden fragments exploded, turning into a sky full of light points.

'NO—!!!' The Heavy Tank mech, having lost its shield, was completely exposed before xingtian no. 1, like a peeled hard-boiled egg. Moreover, due to the prolonged resonance, although the pilot inside the mech suffered no external injuries, his internal organs had been churned into turmoil. 'Ugh...' The pilot opened the hatch,He lay on the ground vomiting uncontrollably, bile about to come out.

'Match decided,' Li Mo said flatly. 'Drag that pile of scrap away. The Heavy Tank Clan's alloy Materials are good; perfect for making xingtian no. 1 a new set of braces.'

The entire arena fell into a deathly silence once more. The commentator's mouth hung open for a long moment before he managed to squeeze out a sentence: 'Wh-what kind of tactic is this?' 'Using sound... to sing the strongest defense into pieces?!'

And at that moment, in the Tianhe Peak team's preparation area. Li Mo had already crossed off 'Heavy Tank Clan' in his little notebook. 'Next match.' He looked at the schedule, where the semi-final opponent was clearly written. 【Titan God Clan · Royal Guard.】 【Mech: Shadow of Zeus.】

'Finally facing the local big shot,' Li Mo closed the notebook, a meaningful glint flashing in his eyes. 'But before that, perhaps we should go take a look 'backstage' to see what this so-called titan core really is.'
