Your Body, My Rules

"Can't you wait for the old man to finish charging before attacking? I don't have a backup power source!"

If there were cheat codes for transmigrating into mechs, Yu Xiao would definitely choose the blue pill that lets him slap Bai Ying through the screen.

But the reality was, the moment the pilot and Xingtian completed neural synchronization, the mech's actions and commands would be overwhelmingly controlled by the pilot.

With the neural link established, Yu Xiao couldn't move as freely as when the cockpit was empty. If he were to resist the pilot's commands, their consciousnesses would clash, increasing the mech's energy consumption.

This was extremely dangerous for an older model like him, especially since his pilot, Bai Ying, loved to manually enter overload mode to forcefully boost the mech's performance.

BANG!

Just as the Xingtian mech broke free from the cables, a thirty-meter-tall Aggregate Beast had already ripped open the hangar door!

Its head was shaped like a hammerhead shark, with three pairs of glowing green eyes neatly arranged along the edge of its skull. Its thick, powerful forelimbs allowed it to stand hunched over, and its claws, as large as its head, were capable of tearing through any artificial armor. Three scaled, pointed tails thrashed behind it.

A sub-giant beast adept at close-quarters combat.

In terms of height, it was twenty meters shorter than the Xingtian mech, but in terms of volume, this thing was its equal!

After all, Xingtian was a first-generation mech, while the Aggregate Beast was a third-generation monster!

"ROAR!"

Yu Xiao didn't know why monsters always roared upon appearing, but for the dishonorable Bai Ying, this was a perfect offensive opportunity.

She didn't spare Xingtian's fuel reserves, pushing the rocket thrusters to maximum power and flying forward to punch the Aggregate Beast's head!

BOOM!

The Aggregate Beast, which had just entered, was sent flying back out of the hangar by a single punch from Xingtian!

Before the Aggregate Beast could react, the Xingtian mech delivered a second punch to its jaw!

Taking two consecutive blows, the Aggregate Beast immediately lost its balance and toppled backward into the ocean!

"Blade deployment!"

Two massive wrist blades sprang out from the black armor. Xingtian leaped forward, landing directly on the Aggregate Beast's body and bringing its blades down on its head!

CLANG!

"Warning, rear armor integrity compromised by 32%!"

Bai Ying, at the controls, grunted, nearly stumbling forward.

Xingtian's wrist blade had missed, failing to sever the Aggregate Beast's head.

The mech's back had been impaled by the Aggregate Beast's three pointed tails!

Bai Ying, having lost her balance, hadn't regained it when the Aggregate Beast's tails launched a second assault!

Suddenly, the Xingtian mech automatically entered overload mode without any command from Bai Ying. The power of its reactor surged!

In that instant, Bai Ying felt her body being controlled by the mech. Xingtian's waist twisted, and it spun around, slashing at the incoming tails!

"Warning, rear armor integrity compromised by 41%!"

One of the pointed tails had deeply embedded itself into Xingtian's rear armor, severing some support struts.

But Xingtian's wrist blade simultaneously severed the other two tails!

The Aggregate Beast let out a heart-wrenching roar, green ichor gushing from the severed ends of its tails.

"Now!"

Without bothering to ponder the strange occurrence, Bai Ying made a swift decision!

Ignoring the tail embedded in Xingtian's back, she activated the rocket thrusters in her mounted position and brought her arm down on the Aggregate Beast's head!

CRACK!

The sharp blade, propelled by the immense thrust, sliced through the bone and flesh of the Aggregate Beast's head, decapitating it!

Watching the seawater turn green, Bai Ying gritted her teeth and pulled the tail lodged in Xingtian's back.

Under neural synchronization, the pain was no different from pulling a knife out of her own back!

"Warning, rear mech integrity compromised by 43%!"

Xingtian stood up from the Aggregate Beast's body, sparks continuously erupting from the rents in its back.

"That crazy girl really wants me dead!"

If Yu Xiao hadn't forcefully regained control just now, the Xingtian mech would probably have been reduced to scrap metal.

"Did you see that, General? This is my strength!" Bai Ying, emboldened by her first victory, was brimming with confidence.

"No, there are new energy fluctuations around you! Retreat to the hangar quickly, we need to descend to a safe level!"

Before General Chen could finish speaking, two more Aggregate Beasts, newly fused, emerged from the sea!

"It's too late, the hangar needs time to descend. You go down now, I'll hold them off!" Bai Ying had no intention of retreating, instead piloting Xingtian into a combat stance.

"Where do you get the nerve to fight two at once!" Yu Xiao was on the verge of tears. The damage to its back had already reduced Xingtian's speed, and its reactor temperature remained dangerously high.

He couldn't rashly seize control again, or Xingtian would self-destruct and disintegrate from reactor overload before the fight even began!

Ding!

Just as Yu Xiao was in a dilemma, he heard a voice etched into his DNA from his past gaming life.

Whenever he encountered a level he couldn't beat, he would, through his own efforts, press the number keys on his numeric keypad, unleashing a sound of invincibility!

Is it coming!

[Detected host's first kill, Evolution System activated]

[Historical kills have been converted into corresponding Evolution Points]

[Name: Yu Xiao]

[Mech Codename: Xing Tian]

[Machine Spirit Level: Lv. 1]

[Mech Performance: First-generation nuclear-powered armor, Height: 50 meters, Weight: 8000 tons]

[Equipment Modules: Slasher Wrist Greatsword, Heavy Cannon, Backpack Rocket Booster]

[Combat Skills: None]

[Combat Power Rating: D-Class (1300 points)]

[Available Evolution Points: 20000]

"Why the hell did this crappy thing activate at this moment!?"

Yu Xiao was almost amused to the point of anger by the system's timing, but he had to figure out how this so-called Evolution System worked right now, otherwise, it would be too late when Bai Ying piloted him into the fray.

The power output of the reactor instantly surged to its maximum, the scorching heat almost cooking Bai Ying, who was standing in the cockpit!

Yu Xiao's "Mech Brain" entered an unprecedented overloaded state, and he quickly understood the operation of this system!

The entire Evolution System revolved around Evolution Points. As long as the Xing Tian mech achieved a kill, it would gain corresponding Evolution Points. The higher the monster's level, the more points awarded.

However, kills were also graded. If Yu Xiao killed a monster independently without any assistance, he would receive 100% of the reward points. But if the monster received other attacks, points would be awarded based on the proportion of damage Yu Xiao dealt.

In addition to this, there were two special reward mechanisms:

1. If Yu Xiao killed a monster never seen before, he would receive 200% of the Evolution Points for achieving the first kill.

2. If the monster's level was [Unique] or higher, Yu Xiao would not only receive Evolution Points but also directly obtain equipment modules or combat skills with special abilities.

What Yu Xiao didn't expect was that as a legendary first-generation mech, the Evolution System had converted all of Xing Tian's historical kills into Evolution Points and given them to Yu Xiao.

However, since the first-generation monsters were generally weak by current standards, the total points added up weren't that many.

Evolution Points could be used to redeem rewards in the shop. To Yu Xiao's surprise, the types of rewards in the shop far exceeded his expectations.

The most numerous items in the shop were mech upgrades and equipment modules, ranging from whole-unit to part upgrades. Yu Xiao only flipped through a few pages and found dozens of them!

Some even contained technologies that humans had not yet mastered!

Not only that, but the shop also had a special category for Machine Spirit Evolution. However, the items in this category were too abstract, and Yu Xiao couldn't figure out what a Machine Spirit was in a short time.

Yet, his eyes immediately caught an extremely special item.

[Machine Spirit Manifestation: Appear in the human world in a biological form and switch between Machine Spirit and biological forms at will.]

[Required Machine Spirit Level: 3]

[Price: 100,000 Evolution Points]

Becoming human was possible!

"Roar!"

The roar of a Congregated Beast pulled Yu Xiao back to reality. Bai Ying had already controlled Yu Xiao and charged towards the monsters!

"Can you not be so reckless!"

Yu Xiao was furious. He could only use the last few seconds of the charge to hastily redeem two part upgrades – the Turbo Nuclear Reactor and the Encapsulated High-Intelligence Holographic AI Interaction System.

The former was to extend Xing Tian's precarious mech lifespan and greatly enhance its performance.

The latter would serve as a Machine Spirit vessel, allowing Yu Xiao to communicate with the pilot, Bai Ying, and reduce energy consumption when he controlled the Xing Tian mech.

Both parts were core components of the mech and were expensive, consuming a total of 16,000 Evolution Points from Yu Xiao!

[Redemption successful. System will complete delivery within ten minutes.]

"What the hell, there's even a delivery time!"

Yu Xiao had expected these parts to be loaded onto him immediately after placing the order.

Even if loading from a four-dimensional space out of thin air was unreasonable, a couple of light beams descending from the sky and striking the Xing Tian mech would have sufficed as a process!

What kind of backward system would require the host to wait ten minutes for logistics delivery in an era of cyber-punk technological evolution!

But the money was spent, and the goods were shipped. He had to endure these ten minutes!

Bang bang bang!

The twin barrel cannons on Xing Tian's back were not idle either, firing at one of the charging Congregated Beasts!

The fierce artillery fire struck the Congregated Beast, but it only managed to slow its advance!

The model of the Xing Tian mech's cannons was too old; their power was insufficient to penetrate the armor of the new generation of monsters!

"Then let's go with brute force!" Bai Ying controlled Xingtian, charging at full speed and swinging his blade at the Aggregated Beast's head.

The Aggregated Beast raised its claws, blocking Xingtian's sharp edge, while its other claw lunged straight for Xingtian's chest!

Thump!

Xingtian also blocked the Aggregated Beast's attack. The two sides' fists met, forming a stalemate, neither able to free a hand.

However, the Aggregated Beast had a tail, but Xingtian didn't.

Three sharp tails shot towards Xingtian's head at a speed Bai Ying couldn't even react to.

The next second, Xingtian's head was pierced on the spot!
