National destiny: Starting with a coffin, building an aircraft carrier is broadcast live globally.

Ultimately, no one chose to upgrade the ruminant digestion module.

He turned off the module evolution panel and controlled [Deep Sea Shadow] to resurface.

The persistent, teeth-grinding fish didn't follow; instead, it turned around and swam away boredly after they surfaced.

The conversion efficiency of the ruminant digestion module is now sufficient for their daily consumption.

There's no need to use up your remaining evolution points for a "super dive" feature that you won't need for the time being.

【Deep Sea Shadow】With the current structural strength, the maximum safe depth is probably only about 1,000 meters. Even with a counterweight module, it would be gambling with the lives of everyone (except Ivan).

Renyi likes to gamble.

However, he prefers to take gambles that he can handle after careful consideration, so he doesn't prioritize the evolution module.

The remaining less than 900 evolution points should be used wisely.

After all, opportunities to gain evolution points for free, like those from volcanic eruptions, are rare and hard to come by.

You have to be very careful with money when supporting a large family!

He tapped the smooth handrail unconsciously.

"Klaus, I want a cannon."

Having solved his housing problem through the evolution of [Deep Sea Shadow], he no longer felt threatened by any other player.

So the next step is how to 'hunt' more efficiently.

Whether it's the pseudo-Abyssal Sea Dragon or the Carnival Tentacle, their counterattacks are too passive.

Although he was quite confident in his and Ivan's abilities, every battle he fought was tantamount to putting himself in danger.

He needs...

A safer and more efficient ranged attack method that does not rely heavily on combat power.

A fishing cannon, or a harpoon cannon, will also work.

"..."

"gun?"

Klaus, Ivan, and Sato Jiro all looked at Ren Yi at the same time, each with a different expression.

Ivan was beaming with excitement.

"Like those pirate cannons?"

Klaus, however, looked serious.

"Sorry, boss... I might not have introduced myself. I've only ever built cars, the kind with four wheels that run on the ground..."

Oh, so what?

Random & Ivan: ლ(╹◡╹ლ)

"The principle is similar... but what about kinetic energy? Gunpowder? Air pressure? The equipment and materials are completely different things..." Klaus paced back and forth in the small room, scratching his hair in frustration.

"I had previously looked into a really funny project."

He suddenly stopped, his face showing a mixture of disgust and excitement, and hesitantly began to speak:

"In the new energy sector, a self-proclaimed clever designer proposed a 'revolutionary safety solution'."

He paused, seemingly organizing his thoughts to describe just how outrageous the plan was.

"He proposed that in the event of an irreversible and severe collision, the battery pack be launched from under the vehicle using an ejection device. This was euphemistically called 'tail-cutting survival,' to prevent thermal runaway of the battery from causing a secondary explosion, thus ensuring the safety of the passengers on board."

Klaus rolled his eyes as he said this.

"Do you know what this means? You're driving normally on the highway, and suddenly a lithium battery pack weighing several hundred kilograms and on fire flies past you—it's no different from being hit by a bomb!"

[Holy crap! What a genius! A walking bomb, huh?!]

[The imagery is so vivid! A terrifying high-speed chase with a battery pack falling from the sky!]

[What a clever trick! It's like saying, "Better to sacrifice your fellow Daoist than me!"]

"That project was absolutely stupid," Klaus concluded, "but I thought it was 'fun' at the time..."

So I studied it carefully.

"Theoretically, we could replicate it, but that's electromagnetic, and we don't even have electricity... We can't expect Ivan to generate electricity with his love, can we?"

Ivan, who was nodding beside him, was left bewildered.

He grasped the core contradiction.

"Gunpowder and electromagnetism are so complicated, can't we use pure physics?" He gestured, "How about building a large crossbow, or... a catapult?"

Klaus gave Ivan the look he gave a caveman.

Then turn to any interpretation:

"As far as I know, the damage that a weapon made from pure mechanical catapults on Earth could inflict on large mutated creatures is probably... better to just launch us as cannonballs."

Ivan puffed out his chest. "I'm definitely stronger than a regular rock fork!"

"..." Klaus pinched the bridge of his nose wearily.

There's really nothing in common with a brute who only builds muscles.

[Hahaha, Ivan is seriously considering the feasibility!]

[Klaus: I'm tired. Let's destroy it.]

[Ivan the humanoid cannonball, fire!]

[Don't be surprised, if Ivan were to drop it, it might really be as bad as a cannonball...]

"electricity……"

They arbitrarily interrupted their conversation.

"We have bioelectricity."

Since the power of flesh and blood is stronger, then let's use the power driven by flesh and blood.

Not long ago, they had acquired a core containing immense energy.

With any thought,

Among a bunch of miscellaneous material icons, I found that heart, about the size of a human head, still beating slightly.

It was the [Pseudo-Dragon Heart] that was separated from that [Pseudo-Abyssal Sea Dragon].

The moment the heart appeared, a violent aura swept over us.

Xiao Jiu even sprang up from the helm with a "whoosh," shedding suspicious "tears."

He gently patted Xiao Jiu's head to comfort her, then focused his attention on the system panel.

[High-level energy core detected: Lv5 Elite Pseudo-Dragon Heart (Rare)]

[Addable Module: Biokinetic Energy Module (MAX)]

[Function: Provides the vehicle with an independent bioenergy source, which can be used to store and power specific functional modules.]

[Evolutionary Requirements:]

【1. High-Energy Core (1/1) ✔】

【2. Flexible biological catheter (37/30) ✔】

【3. Highly Active Regenerating Body Fluid (120/50) ✔】

【4. Evolution Points (893/500) ✔】

This is it!

The three of them had their eyes light up.

"evolution."

[WARNING! Core material level is too high and incompatible with the current vehicle Deep Sea Shadow (LV3)!]

[Forced installation has a 50% chance of causing module distortion, a 70% chance of causing structural instability in the hull, and a 99% chance of causing energy overflow damage!]

[Should we continue?]

A series of bright red warnings popped up, making one's heart pound with fear.

Any: "..."

What a waste of your time.

It seems that putting a Level 5 heart into a Level 3 ship might cause a 'brain hemorrhage'.

"This heart is too high-grade; the ship can't move it."

Klaus said with some disappointment.

"Don't rush."

Once you reach a higher level, switch to a lower level.

He needs another heart with enough energy, but not so much that it would overwhelm the Deep Sea Shadow.

[Mutated Crocodile-Mouth Shark Heart (LV4 Elite)]

[Review: Powerful and potent; it pumps not blood, but rage against the world. PS: Not recommended as a Valentine's Day gift.]

The elite heart, which had been left alone in a corner of the warehouse, can finally shine again.

System panel refresh:

[Energy Core Detected: Heart of a Mutant Crocodile-Mouth Shark (LV4 Elite)]

[Addable Module: Biokinetic Energy Module (MAX)]

[Function: Provides the vehicle with an independent bioenergy source, which can be used to store and power specific functional modules.]

[Evolutionary Requirements:]

【1. Energy Core (1/1) ✔】

【2. Flexible biological catheter (37/20) ✔】

【3. Highly Active Regenerating Body Fluid (120/30) ✔】

【4. Evolution Points (893/300) ✔】

This time there was no glaring red warning, and the required materials were also drastically reduced.

"Guys,"

"Looking forward to it, now we have the 'engine'."
