Train Survival: You're really trying to survive!

They packed up their belongings, planted the crops that needed to be planted, and smelted the ores that needed to be smelted. The team returned to their old rhythm.

The train traveled through the void and came to a steady stop on the platform of Blue Star City.

This return journey through the void took a total of 7 days.

After getting out of the car, Su Li stretched her body. "Hmm~ Blue Star City is still the best. The air inside the car is circulating and has a smell of algae. It's a bit hard to stay still."

The smell from the air circulation was very faint, but it couldn't stop Su Li's keen sense of smell.

“You can go to the small world,” Sun Keke said, puzzled.

Su Li shivered. "You haven't been to the small world in a long time, have you?"

"Hmm, I've been making clothes, what's up?" Sun Lili asked curiously. It had been several months since she last went to the Little World.

"The current state of this small world is truly beyond words," Su Li said with a helpless expression. "The small world raises a lot of creatures, and since creatures eat, they excrete, resulting in a large accumulation of cow dung in the small world."

"Moreover, the various fungi that these creatures bring with them are currently engaged in a battle for supremacy within the small world, with all sorts of fungi growing wildly. In short, the small world smells absolutely terrifying right now."

"Ew~" Sun Lili grinned in disgust, then looked at Song Mingyu curiously, "Sister Mingyu, haven't you thought of a way to deal with this?"

"It's alright. Our little world is created. The internal ecosystem didn't evolve on its own; it was grafted from the outside, so it needs a process of mutual adaptation."

"Don't worry, I'm here to harmonize nature. Just wait a while, and everything will be alright." Song Mingyu put her hands inside her white coat, a researcher's demeanor that made her words very convincing.

Ivan had already registered the train information with the staff. In recent years, the management of Blue Star City has become increasingly standardized. Everything is moving closer to the Blue Star that Zuli used to live on.

Noticing Ivan's arrival, Su Li clapped her hands. "Alright, everyone, go ahead and do what you need to do. We'll rest for a day. The train will go into the factory for repairs tonight. Everyone can stay at the same hotel as usual."

"If there are no further comments, this is dismissed!"

The team members said goodbye to each other and left the platform.

Su Li first found Shi Lei and conducted an oil transaction with him.

In this game, converting oil into fuel only requires a chemical furnace, but using the furnace only produces oil-based fuel. All other usable materials are consumed by the system as processing fees.

This is oil, the lifeblood of modern industry. To use it like this is a complete waste, especially for players who develop mechanical systems.

After discussion among the players, some players started offering an oil extraction service, helping other players extract oil for free and even paying them to buy the remaining products after the oil extraction.

This is a win-win situation. Ordinary players only need fuel, which they can extract themselves, and they also have to pay for fuel. By finding mechanical players to extract oil, they not only don't spend money, but they also gain resources. Mechanical players, on the other hand, get the oil they desperately need and continue their great endeavor of advancing their technology.

After handing over the work to Shi Lei, Shi Lei directly increased the fuel supply by 10% based on the oil yield and the amount of crude oil provided by Su Li, and even delivered it to Su Li's door.

After storing the fuel, Zurich began upgrading the train.

First, the train was upgraded from level 6 to level 7.

[200 Black Iron Grade Wood, 200 Black Iron Grade Stone, 400 Elementalized Silver Ingots, 400 Elementalized Copper Ingots, 500 Titanium Ingots, 500 Platinum Ingots, 50 Five Element Crystals, 3 Five Element Essences, 200 Five Element Harmonizing Materials]

All other materials have been collected.

The last material for harmonizing the five elements is the crystallized bone marrow collected this time. A total of 803 units of crystallized bone marrow were collected this time, which is enough not only for level 7, but also for level 8.

The level 7 upgrade plugin was already prepared in the Void, but because Su Li was afraid that something might happen if the train was upgraded in the Void, she never used this plugin.

After her teammates left, Su Li took out the plug-in and used it on the train.

The train components transformed into points of light and merged into the engine. In a short while, the points of light disappeared, and a new engine appeared on the platform.

The front of the car has a more modern design.

Su Li first got into the car to check the effects of the upgrade.

Upon entering the train, Su Li immediately noticed that the temperature was slightly different.

It's currently summer in Blue Star City, with outdoor temperatures reaching around 35 degrees Celsius. Everyone in the city is dressed in summer clothes.

However, the temperature inside the car felt like springtime, making it very comfortable.

"The temperature and humidity are at the levels most suitable for Earthlings."

Su Li understood; this upgrade had granted her the ability to maintain a constant temperature.

Upon reaching the main control panel, a message board popped up, explaining the details of the upgrade.

The train's speed has been increased to 200 km/h, and its maximum speed has been increased to 250 km/h.

This speed is comparable to that of a high-speed train.

[The train's temperature control function has been upgraded, ensuring that the temperature inside the train remains unaffected when the outside temperature is between 200 degrees Celsius and -50 degrees Celsius.]

"It's another feature that's better than nothing," Su Li sighed.

The train features optimized water and electricity systems, enhanced water purification capabilities, and electrical wiring compatible with magical energy transmission.

This is a rather important function; it will determine whether Su Li and the others will need to secretly install magic energy pipes when using various devices in the future.

The Reality Distortion Cannon required Suri to spend extra Survival Coins to create a magic energy pipeline due to power supply issues.

[Gaining the Five Elements Fusion property, the train's external armor is enhanced by the energy of the Five Elements, increasing its defense and magic resistance.]

This is a great feature. Even with barnacle armor, the train's defense is still relatively weak. When fighting the enemy, the squad often has to consider the train's safety.

In particular, the final magic resistance boost not only protects against magical attacks, but also against external magical energy fields, elemental disturbances, and other problems.

[With the upgrade of the train level, when selecting a world, if the filter is based on the train level, the energy levels of the selected worlds will be concentrated in the range of 1.7-2.1.]

Zurich had anticipated the global power boost that the train upgrade would bring.

"Our strength is now sufficient to handle gold-level monsters, so let's increase the difficulty of exploring the world as soon as possible, so we can scavenge higher-level resources and improve our strength."

The resources that Su Li and his group had accumulated were almost exhausted. It was time to acquire more resources, explore beyond their level, and increase their leveling speed.

Next, Su Li arrived at the small world to check on its situation.

The original area of ​​the small world was a circle with a diameter of 8 kilometers. After years of slow expansion, the radius reached 12 kilometers. After this train upgrade, it has expanded to 16 kilometers.

The small world is circular; increasing its radius by 16 kilometers almost doubles its area.

Su Li didn't plan for the newly added area. Sophia and Song Mingyu were planning the planting and breeding according to their own needs. They would just hand it over to them when they returned.

After settling things in the small world, Zuli arrived at the factory to begin the train modification project.
