The "Survival on the Train" game has bugs, it's really laggy!

"Crack...crack..."

Strange changes also began to occur inside the carriage.

Dark green plant patterns began to appear on the originally cold and monotonous metal walls.

They spread from the floor to the ceiling, quickly transforming the entire interior of the carriage into a green space filled with eerie beauty.

Even the incandescent light bulbs overhead, which provided illumination, began to deform and melt under the influence of this force.

The filaments went out, and in their place appeared strange plants emitting a soft, fluorescent glow.

Su Yuan curiously reached out and picked one. It was cold to the touch and looked ordinary at first glance, but this thing could glow.

【Name: Glowing Mushroom】

【Quality: Special】

[Introduction: A type of specially mutated fungus that can absorb free energy from the air and convert it into light energy, making it a highly efficient and environmentally friendly biological light source.]

"Holy crap, even the light bulbs have come to life?" Su Yuan opened his senses and was amazed. His train seemed to have really turned into a plant train.

Su Yuan pressed the glowing mushroom back onto the ceiling, and it seemed to have grown there perfectly, continuing to emit a soft glow.

He walked to the corner of the carriage, where there used to be a simple toilet stall.

Now, that simple toilet made of metal and plastic has disappeared.

Instead, there was a plant with an incredibly peculiar shape?

That thing looks a bit like a giant pitcher plant lying upside down on the ground, except that its "mouth" is facing forward, not upward.

The "mouth" was composed of two thick, lip-like fleshy plant petals, which were slightly open at the moment, revealing a dark, bottomless interior that occasionally emitted a faint fragrance.

"This...this is a toilet?" Su Yuan circled the strangely designed "plant toilet" twice, his face full of bewilderment.

He even reached out and carefully poked those thick "lips".

It has a bouncy texture and is warm to the touch, just like... touching the skin of some living thing.

"How do I use this thing?" Su Yuan instantly conjured up a picture in his mind.

I squatted on it, and then... after I finished pooping, this thing even stuck out a tongue to wipe me clean...

Just then, the train's vibrations finally subsided.

The intense renovation, which lasted for nearly ten minutes, seemed to be coming to an end.

Su Yuan could clearly feel that the entire train had come to life.

It is no longer a pile of cold steel, but a living thing that is breathing and growing.

He walked to the car door and looked outside.

The train's color has completely changed from pure black to this deep and vibrant dark green.

The length of the train body has also increased by about one-third compared to before, with the addition of a brand-new carriage made entirely of plant structures.

The two thick, thorny vines extending from the front of the car were now like two wary venomous snakes, slowly slithering around the car window, full of aggression.

"This is truly a major upgrade." Su Yuan looked at his brand-new "biological war machine" and a very satisfied smile appeared on his face.

He went to the driver's seat to check on Xiao Huo.

As soon as he stepped into the driver's seat, he froze.

The control panel, which was originally filled with various dials and buttons, has now been completely changed.

Apart from the central control panel, which still retains a hint of technology, all other electronic structures have been replaced by various strange plant tissues.

The feeding port below the control panel, which was originally used to contain the core of the small flame, has now disappeared.

Instead, there was a fruit, only the size of a fist, crystal clear, and slowly beating like a heart…

The fruit floated in mid-air, its surface shimmering with a faint golden glow, and inside, a ball of orange-red flame seemed to be burning.

With each pulse, a gentle yet powerful energy travels throughout the entire train via the countless delicate plant roots connected to it.

"Little Fire?" Su Yuan called out tentatively.

The heart-shaped fruit only throbbed slightly, without any response.

It seems it is still asleep.

Su Yuan circled the fruit twice, his heart filled with curiosity.

He reached out his hand, wanting to touch it, but was afraid of disturbing its evolution.

But the next second, Su Yuan's hair stood on end. Almost instinctively, he immediately turned behind him and released bone blades from his arms.

Suddenly, a child appeared behind them, floating in mid-air. The child had green skin, looked harmless, and its gender was indistinguishable.

The child hovered quietly in mid-air, his big, dark eyes curiously observing him.

Behind it, a thick vine hangs down from the ceiling, connecting with its back, undulating slightly with its breath.

Seeing Su Yuan's tense and fearful expression, the child seemed startled and instinctively shrank back.

Then, it tilted its head and timidly opened its mouth.

"Master...it's me, Little Fire!"

Appearance can be faked, and aura can be imitated, but the imprint of the soul is unique and cannot be changed!

Su Yuan has extremely high perception, so he can naturally sense and remember the aura of a soul. Fortunately, they are all the same, and the little brat in front of him seems to really be Little Fire.

Su Yuan finally relaxed his guard, glancing at it with a smile: "You little rascal, I didn't expect you to actually have a body now..."

Little Fire retracted its vines and came to the ground. Su Yuan noticed that its feet were now connected to the floor again. It seemed that Little Fire needed a constant power supply, otherwise it could not maintain this form.

However, now that Xiao Huo has a physical form, it can do even more things.

Moreover, Su Yuan could clearly sense that the energy contained in this little thing was more than one level stronger than that of the previous flame core.

"Then... can you turn back into your original form now?" Su Yuan asked again.

"Sure!" Little Fire nodded, and then, to Su Yuan's astonishment, his body "poof" turned into a ball of orange-red flame, and then "whoosh" burrowed into the still-beating heart fruit below the control panel.

The next second, the fruit shone brightly, and the temperature in the entire cockpit suddenly rose.

[Master, this is my current state! This fruit is my new core, and the power source for the entire train!]

Xiao Huo's familiar voice came through the speaker on the dashboard once again.

Su Yuan watched this scene with awe.

It seems that Little Fire can now freely switch between "humanoid" and "core" forms.

"Can you still control the train? What about the new features?" This was what Su Yuan was most concerned about.

【Of course! Master! I am now completely one with the train! I am the train, and the train is me! I can control all its functions!】

Xiao Huo's voice was filled with pride.

[And because of this mutation, I've also awakened a new ability!]

"A new ability?" Su Yuan's eyes lit up. "Tell me quickly, what kind of ability is it?"

Hehe, Master, don't be in such a hurry.

With the sound of a small fire, the heart-shaped fruit flashed again, and the green little boy reappeared in front of Su Yuan.

He stood proudly with his hands on his hips, a look on his face that said, "Praise me!"

"Master, I can now control all the plants on the train! Look!"

As Xiao Huo spoke, he waved his little hand.

The next second, the glowing mushrooms on the ceiling of the carriage, which had been emitting a soft glow, suddenly changed color in unison, from a soft white to a bright yellow, illuminating the entire carriage as if it were daytime.

"I can also darken them!"

With another wave of his hand, Little Fire caused the glowing mushroom's light to dim instantly, leaving only a faint glimmer that was just enough to make out the surrounding outlines.

"How was it? Pretty impressive, huh!" Little Fire looked up at Su Yuan with an expectant expression.

Su Yuan smiled slightly: "Then you can control those two tentacles outside, right?"

Little Fire nodded proudly, "Of course I can control it. If there are any malicious people in the future, or if we encounter danger, I might be able to help you solve the problem without you having to take action."

Xiao Huo then playfully grabbed Su Yuan's arm and smiled, "All of this is thanks to you, but from now on we're really in the same boat~"

Su Yuan nodded. Little Fire hadn't lied to him, because he had just obtained the hidden information.

After the seed was planted, his train became one of the special trains. As a result of the mutation, the train has completely broken free from the control of the train world.

If a person dies or exceeds the maximum stay time on the platform, the train will not disappear, but will perish with him.

The good news is that Xiao Huo died, but it won't affect him. However, the price is that he will lose the train. Without the train, it will be very inconvenient in this world. So, in the future, the two of them will really be in the same boat, no, in the same train.

Just then, the notification sound indicating that the upgrade was complete finally arrived, albeit belatedly:
