If it were about collecting money, Li Cunxu would definitely pay it, but what's required is credits.

The freshly acquired one hundred credits have already been used to exchange for an opportunity to explore the mechanical deconstruction secret realm; he doesn't have any other credits left to pay.

"Do I need to earn some credits, look at the remaining intelligence, and then go exploit the secret realm?"

Li Cunxu considered for a moment and decided to head straight for the secret realm without looking at the remaining intelligence.

Viewing the remaining intelligence requires ten credits.

Except for the freshman list, it isn't that easy to earn credits; tasks are time-consuming and exhausting. By the time he earns ten credits, the twenty credits for the top 100 first-year freshmen would already be distributed by the end of the month.

Might as well do nothing.

As for entering the top fifty, then earning two hundred credits.

Li Cunxu thought about it and gave up, mistakenly believing that the standard of the top one hundred was about the same as the Faceless Man's level.

He was unaware that every month, the Faceless Man's ranking would return to seventh on the freshman list.

Apart from the difficulty in collecting credits, there was another reason Li Cunxu didn't check the remaining intelligence.

The intelligence that required payment likely wouldn't be much help in the mechanical deconstruction secret realm.

If it really was useful, then why hadn't previous exploiters used it to successfully conquer the secret realm?

Li Cunxu arrived at the school's portal governing the secret realm.

Secret Realm Hall.

In the Secret Realm Hall, many secret realm teleportation gates shimmered with dazzling light.

After using the opportunity from the school account to explore the mechanical deconstruction secret realm, the staff gave Li Cunxu a red string with three beads.

The staff introduced, "The red string is braided from the silk of Special Red Fortune Silkworms. Once tied, even gold-level power cannot untie it; you can only return here and use special potion to untie it.

The smallest green bead on the red string is the child bead of the Mother and Child Life Bead. It can detect your vital signs, and once your life ends, we can know through the mother bead.

The mechanical deconstruction secret realm is challenging, so there is no limit on exploration time. As long as your life bead stays alight, the school won't let other explorers enter the secret realm.

The medium-sized red bead is the rescue bead. Crush it, and you will receive rescue from a rescue team, but their rescue is limited; if it's too dangerous, they might be powerless. By the way, don't crush it at will. Rescue is not free; crushing it means you agree to pay a thousand credits."

Li Cunxu asked, "What if I don't have that many credits?"

The staff replied, "You can owe it, but any credits you earn thereafter will go to the rescue team until you pay off the thousand credits.

This largest yellow bead is the Secret Realm Traction Pearl. Just hold it firmly for half a minute and say 'I want to return,' and you'll be brought back to school from the secret realm."

Stepping into the secret realm, the world spun around him.

A white flash, not darkness, unfolded before his eyes.

Li Cunxu was immediately reassured.

The mechanical deconstruction secret realm is fairly safe during the day, but very dangerous at night.

Li Cunxu found himself at the bottom of a pit in the ruins. As he climbed up, possibly due to his movements, a nearby broken wall labeled with a red 'DEMOLISH' character collapsed.

Climbing to the top of the ruins, Li Cunxu saw a city under fiery reconstruction.

The scorching sun cast its burning heat on this city of perpetual rebuilding, and on the empty roads, construction robots using unicycles as their mode of transport left deep and shallow marks on the compacted mud surface, resembling a group of mute workers tirelessly working.

Mechanical arms flew up and down, stacking bricks, each placed with precision. High-rise buildings gradually rose on the horizon, seemingly challenging the sky and proclaiming they would construct a beautiful city.

Li Cunxu did not act rashly.

"Xiaoruan, set up a Land of Rebirth, prioritize reviving the Iron Slime."

Iron Slimes at level zero resurrected and began devouring the rebars on the weight-bearing walls of the ruins.

Along with Xiaoyi, the Dark Raven, Mechanical Pupil, and Li Cunxu, they built a shelter camouflaged as ruins. The shelter had several viewing slits facing the city, allowing them to observe the city's movements.

The sun set, and the moon took its turn.

The construction robots that were diligently building the city now had their eyes glowing red under the cold moonlight. A leading construction robot pulled out a giant stamp, pressed it on a wall, immediately leaving a 'DEMOLISH' character.

The surrounding construction robots picked up sledgehammers, transforming into demolition robots, and began tearing down the newly constructed high-rise buildings.

Demolition was much faster than construction. In just a couple of hours, the day's worth of high-rises had been dismantled.

With nothing else to do, the demolition robots began fighting each other, with I-shaped steel beams, hammers, and power drills flying chaotically.

Observing the death and damage of the demolition robots, Li Cunxu muttered, "Looks like there's daily fighting and many demolition robots die daily. So, the number of demolition robots should be limited, right? Why are there still so many demolition robots in this secret realm?"

"Could there be a mechanical mother here?"

A mechanical mother, similar to the Waste Queen; where the Waste Queen can generate Scrap Kids, the mechanical mother can too, and even more. It is like the queen ant in an ant colony, massively reproductive.

As dawn broke and the first light of morning shone upon the ruins, the demolition robots, red-eyed from fighting, regained their senses and transformed back into diligent construction robots, embarking on a new cycle of city-building.

"Recovered? Could it be that sunlight breaks the data virus within the construction robots?"

The demolition robots that survived until daylight typically rose two or three levels after the life-and-death battle.

Soon, a large group of construction robots emerged from a subterranean chasm in the ruins, joining in to help build the high-rises.

"The mechanical mother might be in there."

"Xiaoyi, send a level divisor to mimic a demolition robot and infiltrate the chasm to find the mechanical mother."

The key to exploiting the secret realm lies in the core, usually in the hands of the strongest creature within the secret realm.

The mechanical mother of the demolition robots, being top-level bronze, might hold the core.

Moments later, the little white spider shook its head.

"Underground, the demolition robots are even more aggressive than those on the surface. They attack on sight. My black iron duplicate was killed by others before getting through."

The little white spider sent a bronze duplicate, which also didn't make it far before being killed.

Besides learning and development abilities, the little white spider was otherwise quite weak; it was normal for its bronze duplicate to be killed.

Li Cunxu rubbed his temples.

"My mistake; I should use smaller insects."

With both of the little white spider's duplicates gone, they had to wait for 24 hours to revive and try again.

During this time, Li Cunxu captured a construction robot for experimentation.

He knocked it out... No, upon capture, Li Cunxu immediately applied an information-blocking red seal, disconnecting it from the network to prevent it from contacting others.

Li Cunxu experimented with the construction robot, discovering that the transformation to a demolition robot wasn't due to the absence of sunlight or moonlight.

It was due to them reaching a specific time zone, simultaneously transforming into demolition robots.
