"What?" Yu Nian asked curiously.

"Our efficiency is still too low, so before we begin the investigation, we need to renovate the train once more," Bai Cheng explained calmly.

After Bai Cheng shared her thoughts, everyone felt it was feasible.

After all, there were no maps or navigation here; wandering aimlessly on a train was simply a waste of time.

And renovating the train now was indeed a bit troublesome.

Since entering the Infinite Realm, the system had fallen into a deep sleep, making the efficient method of relying on the detection console to scan for resources and plan routes no longer viable.

Bai Cheng and the others could only rely on the most primitive manual searching and judgment.

Fortunately, everyone possessed King-level strength, moving swiftly with sharp senses; even searching for specific materials in the vast Emerald Sea wasn't impossible.

The renovation plan was proposed by Bai Cheng and led by Lan Xiaoyu.

The train was originally divided into three floors: the first floor contained the cockpit, Employee dormitories, and the power area; the second floor was for planting and livestock; and the third floor was the living quarters for Bai Cheng, Leng Ningxue, and Yu Nian.

Now, they decided to add a new carriage at the end of the first floor, specifically for storing and building "element power vehicles."

The principle was the same as the powered railcar, except the latter was a system product that required tracks to move.

Since Bai Cheng and the others were continuing the renovation, they naturally wouldn't keep the redundant restriction of tracks.

They wanted to build a vehicle that could move freely in the wild.

The vision was for a wheel-less vehicle driven by the driver's own elemental power, capable of hovering and traveling at high speeds, suitable for rapid movement between islands and making up for the train's inability to get close to them.

However, building nine element power vehicles required a wide variety of materials, including high-conductivity elemental crystals, lightweight but tough alloy frames, and stabilized magnets for the levitation cores.

These materials were extremely rare on peaceful islands like Chao Yin Island.

Therefore, lately, Bai Cheng and the others had not rushed to other islands to track the invaders; instead, they devoted all their energy to searching for materials.

Using the train as their base, they split up daily, using their King-level perception to scan the surrounding waters and islands.

Although the Emerald Sea was vast, most islands were resource-poor, until they discovered a key mineral vein on a deserted cliff island.

This island had steep terrain and sheer cliffs, far from the residential areas of the Sea People or other races, yet it held abundant elemental crystals and natural magnetic rocks.

Bai Cheng led a team to the island, using their power to excavate and collect, and after several days, they finally gathered most of the necessary materials.

With the materials ready, everyone quickly threw themselves into construction.

Lan Xiaoyu had an extraordinary talent for mechanical structures; with the help of Leng Ningxue's ice power for shaping and Yu Nian's metallic element refining, the frame of the new carriage was soon completed.

The levitation cores and power structures of the nine element power vehicles also gradually took shape.

Bai Cheng was responsible for the overall planning and energy circuit calibration, ensuring each vehicle could resonate perfectly with the driver's elemental power.

During these days, the train remained anchored in the waters near that deserted island.

Everyone worked by day and rested by night; although they didn't actively investigate, the occasional passing shadows of strange ships or elemental fluctuations in the distance made them feel that the Emerald Sea was not at peace.

Elder Moto's concern that "other islands might also be under attack" always weighed on their minds.

"We have enough materials. In two days at most, the element power vehicles will all be finished."

Lan Xiaoyu wiped the sweat from her brow and reported the progress to Bai Cheng.

"Then we can use the cars to quickly patrol the surrounding islands; the efficiency will be much higher than using the train."

It couldn't be helped; without the system's assistance, building equipment was just that slow.

And this was even with the help of a mechanical genius like Lan Xiaoyu.

However, it was also better without the system's assistance; at least for now, they didn't have to worry about being monitored.

Bai Cheng had speculated about this result; it was likely that the system had expended too much energy to send them into the Infinite Realm and was forced to go dormant.

During this precious time, the first thing Bai Cheng and the others had to do was investigate whether what the man in the valley had said that day was true.

Was the system really a "god" coveting this world?

Standing at the door of the new carriage, Bai Cheng looked out at the silent sea with a profound gaze: "Yes. Once the vehicles are ready, we'll start our investigation from the nearest outer islands.

If those invaders are truly an organized gang as the elder said, we'll encounter them sooner or later."

Yu Nian jumped down from the roof, still holding an unpolished crystal, and laughed, "Maybe we can save a few more tribes like the Sea People and pick up some specialties like the Star-Patterned Sea Bream along the way!"

Leng Ningxue shook her head slightly, but a cold glint flashed in her eyes: "There's no need to look for trouble, but if we encounter it, we'll deal with it all at once."

The sea breeze blew through the gaps of the not-yet-sealed new carriage, carrying a salty scent.

The renovation project was nearing its end, with only the final testing remaining.

And the truth beneath the undercurrents of the Emerald Sea was about to surface as they set off once again.

Soon, all nine element power vehicles were completed under Lan Xiaoyu's leadership.

The streamlined bodies shimmered with the characteristic faint glow of elemental crystals, the levitation cores running stably, silently hovering an inch off the ground.

Bai Cheng, Leng Ningxue, Yu Nian, plus six Employees—exactly nine people—each piloted one.

"With Chao Yin Island as the center, search outward in a fan shape."

Standing by her car, Bai Cheng traced several directions on the sea chart with her fingertip.

"Stay hidden and prioritize collecting traces of the invaders' activities."

The nine cars sped out of the waters where the train was anchored like arrows from a bow, skimming across the calm, phosphorescent surface of the Emerald Sea toward the scattered islands.

Where the cars passed, they left only fleeting ripples on the sea surface.

However, the results of several days of investigation left everyone with furrowed brows.

They found nothing.

Lanyi Island to the east, where the Feiyu Clan lived, was said to have been controlled by an invader codenamed Aquila, with tall watchtowers and cages.

But when Yu Nian arrived, the towers were empty and the cages broken, leaving only a few scattered metal fragments and scorch marks.

The members of the Feiyu Clan were still shaken, confirming that those iron-winged villains had evacuated in a hurry several days ago, taking all important supplies with them.

The same was true for Panshi Island to the south, where the Yanke Tribe was located.

The tunnels where they had been forced to mine crystals were now unguarded, with only crude sheds and abandoned tools remaining.

The Yanke Tribe elder mentioned that the leader known as Capricorn and his subordinates had left by ship overnight shortly after °• N 𝑜 v 𝑒 l i g h t •° the huge commotion from the direction of Chao Yin Island.

Employees investigating the west, north, and other directions also sent back similar news: the invaders' strongholds were deserted, leaving only some broken living traces and a small amount of worthless junk.

Some islands had only just ended their chaos, with local races dazed as they cleaned up the mess, completely unaware of why their oppressors had suddenly abandoned the territories they had occupied for so long.

In the end, the nine cars found nothing and could only return to the train one after another.
