Train Survival: One colored hexagon per level!

A series of system notifications rang in his mind, and Lu Xingyuan's mood couldn't help but become excited.

I finally reached level seven! It wasn't easy!

He quickly checked the three newly displayed train modification options.

A light touch on the first modification caused a flash of deep blue light.

It's a blue makeover!

[Onboard Workshop - Blue (50 Train Coins): Transforms a train carriage into a multi-functional processing workshop. Equipped with basic lathes, milling machines, welding equipment, and a fitter's table, it can cut, drill, grind, and weld materials such as metal, wood, and plastic. It can process and manufacture parts and simple equipment of quality level 5 and below.]

what!

Lu Xingyuan subconsciously looked at Rambo beside him.

Teemo looked at him too, and said with surprise:

"This was prepared especially for you!"

Rambo's eyes widened in disbelief!

As a self-taught mechanic, he never had a workshop that truly belonged to him.

Each time, he would assemble the salvaged parts in a dirty, open-air setting and install them on his Tristi.

He would drool whenever he looked at Heimerdinger's super laboratory.

But he knew very well that this was a dream he could only dream of!

But now... it seems like the dream has come true!

Although it's a far cry from that so-called super laboratory, it's still better than before, isn't it?

"Boss..."

Rambo's lips trembled slightly:

"Are you sure you want to take it? Don't you have a gold upgrade card?"

With Teemo's explanation, he also understood the function of the golden modification card, knowing that it allows him to choose an unsatisfactory modification to replace it.

"I'm very happy with this renovation! Why would I want to replace it?"

Lu Xingyuan said with a smile:

"Don't forget that you are an important partner to us."

"Boss!"

Rambo's tear ducts completely broke down.

But being naturally proud, he was too embarrassed to shed tears in front of so many people, so he could only turn his head away and explain that sand had gotten into his eyes.

Lu Xingyuan waved his hand and spent fifty train coins to acquire the onboard workshop.

Let's choose the newly added last carriage as the carrier.

Keep a distance so that Rambo's tinkering doesn't disturb other people's rest.

Lambo couldn't wait to rush to the vehicle workshop.

It was clean and tidy inside, brightly lit, and had all kinds of equipment, all neatly arranged. It was much better than his temporary laboratory!

"I love it here!"

Rambo excitedly kissed the workbench.

If he hadn't still had two upgrades left to draw, he really would have stayed here and never left.

The next step is the second modification.

The moment my finger touched it, a faint green light flashed.

[Loudspeaker Warning System - Green (12 Train Coins): A high-powered directional speaker is installed on the roof of the train, capable of playing warning voice messages, low-frequency animal-repelling sound waves, or purely intimidating noise. Covers a range of 500 meters.]

This modification immediately made Lu Xingyuan frown.

It might be useful for other train conductors, but for him, it's really useless.

"I think we can just use a gold upgrade card to replace it."

Lamb further suggested.

"Don't rush, let's look at the last modification."

Timo tugged at him, signaling him to calm down.

Lu Xingyuan temporarily shelved the second modification and did not rush to confirm it.

The third modification is also blue.

【Vehicle-Mounted Howitzer - Blue (80 Train Coins): A retractable 105mm vehicle-mounted howitzer is mounted on the roof. It features an omnidirectional rotating turret with an elevation range of -5° to +70°, a maximum range of 8 kilometers, and is operated from an in-vehicle control console with an automatic loading system. The maximum rate of fire is one round every 15 seconds. A single high-explosive shell can destroy lightly armored targets, overturn small to medium-sized buildings, and has a kill radius of approximately 15 meters against dense hordes of corpses.】

Restrictions: The train must be stationary or traveling at a low speed below 20 km/h when firing; a 10-minute cooldown is required after firing 5 rounds consecutively. Five high-explosive shells are included; subsequent ammunition must be produced or searched for independently.

"It's a vehicle-mounted weapon!"

Timo exclaimed in surprise.

Lu Xingyuan was not surprised by this.

The fact that upgrading to level 7 requires so many fire control computing modules already hints that the level 7 train modification will definitely include vehicle-mounted weapons!

Of course, these vehicle-mounted weapons also vary in quality.

If it were Gu Wanqing, she would likely get a purple or gold-level weapon.

After a moment's thought, Lu Xingyuan spent eighty train coins to modify the vehicle-mounted howitzer.

He chose to mount the howitzer on the roof of the third carriage.

In this way, both the beginning and the end can be taken into account.

With a low, mechanical clicking sound, the heavy roof of the carriage burst open to both sides, and a 105mm vehicle-mounted howitzer, entirely black in color, slowly rose up.

The turret slowly rotated, supported by hydraulic rods, like a black behemoth just awakened from a steel cage.

The afterglow of the setting sun painted the cold composite armor, reflecting off the cannon muzzle as a blinding glint that swept across the entire wasteland.

At the same time, a gun control console firing button has been added next to the operating system inside the vehicle. With a light press, a powerful high-explosive shell will be fired!

"Unfortunately, there were only five shells."

Timo pouted, thinking the system was stingy for not sending more ammunition; five hundred wouldn't have been too much!

Fortunately, there are people selling high-explosive shells in the trading channel, so I can just buy them from them later.

Suppressing the urge to test the power of the howitzer, Lu Xingyuan turned to look at the second green modification.

However, just as he was about to launch it, he suddenly remembered something.

"etc!"

"I think I also have a white makeover project!"

This is a bonus of the "extra opportunity" for train modification.

Extra Chance (Purple): Breaks the usual limitations, increasing the number of random modification options that appear with each upgrade by 1. Note: The quality of this extra option is always white.

So, could you exploit a bug?

The green modification was kept, and the white modification was replaced with a gold modification card.

Even the worst of all, a loudspeaker warning system is a green upgrade, which is better than a white upgrade.

The white paint job is done.

[First Aid Kit - White (2 Train Coins): Obtain a basic first aid kit containing a tourniquet, gauze, alcohol swabs, iodine, band-aids, fever reducer, anti-inflammatory drug, painkiller, and common cold medicine. Replenish the kit using Train Coins.]

Lu Xingyuan glanced at it briefly and then began his shady dealings.

Unfortunately, a failure message popped up.

The system obviously doesn't allow you to exploit this loophole.

I already get an extra white modification with every upgrade, but this is just too unfair.

Left with no other choice, Lu Xingyuan had to obediently replace the green renovation project.

A strong golden light flashed continuously.

Teemo and Rumble were both extremely nervous.

Alice, who was standing to the side, had already clasped her hands together and was silently praying for Lu Xingyuan.

Finally, the light faded, the golden upgrade card was successfully activated, and the replacement was completed.
