I became a god by treasure hunting after arriving 500 years early

These Mermen touched the thick walls, seemingly understanding Human's approach.

They were not at all polite, eating and drinking as if on a public-funded trip, meanwhile, they spoke probing words to each other.

"Pandora Crystal Stones are indeed nice... There are some underwater too, but we have never found a really good vein. I wonder if Human Civilization can sell some?"

"We do have a small stock here, but we also need to build a proper Sky City..."

Both sides spoke in ambiguous terms to prevent giving away too much information.

Lu Yuan actually didn't like these kinds of scheming plots; after listening for a while and finding it unproductive, he temporarily left the room.

Several hours later, Sky City arrived.

Large Puppet machinery clutched the box and placed it on a rail train, and positioned the cargo hold at a designated spot, under the escort of soldiers, numerous Merman scientists came out.

They subconsciously glanced around, seeing a large group of soldiers, buildings of Sky City, the rail train, Puppet machinery, and the Engravings on the walls—it was an inevitable measure; Humans couldn't exactly put a hood over the heads of the Mermen, that would be far too impolite and not conducive to future cooperation.

The whole machinery adjustment process went smoothly.

It lasted approximately 30 days, with people providing food and drinks, these Merman experts worked overtime daily in their rooms, finally getting the machinery to operate normally.

"Now we'll teach you how to use these instruments, next it's up to you to maintain them."

"If the machine breaks down midway, look for us again, a new fee will be required."

This Merman expert, holding a blue pill called "D-Omega Active Drug," supposedly eliminates free radicals and improves cellular vitality.

Pure Materialism technology, very rare in this era.

This Merman swallowed the medicine into the box on his own, his scales bristled, and he turned to leave.

"That's it? He didn't tamper with anything, right?" Lu Yuan watched at the door for a month.

For some reason, he always had an uncomfortable feeling but could never pinpoint the cause.

He also picked up a little pill and studied it for a while, finding nothing unusual, and it didn't require any Idealistic elements.

"This pill is made with pure Physical Technology; we just need to provide some raw materials, and it can continuously produce the pills."

"Of course, we won't rashly use it on Humans; first, we use a batch of small animals for biological experiments, ensure its safety, then proceed to promote it," said the research expert.

"What about the machine?"

"It's also a machine of pure Materialism technology... Although it still includes many uncrackable black-box technologies, it is purely physical technology. No Hume index could be detected."

"Pure Physical Technology..." It has been a long time since Lu Yuan heard this term, feeling somewhat nostalgic about the time on Earth before the Supernatural era, when everyone used pure Physical Technology, which also created many miracles. Now, the Human 18th Civilization's technological tree is more inclined towards Mind.

"Indeed, this machine is extremely complex, including some high-tech chips. We need a long time to thoroughly study how it operates. These chips are quite durable; for decades, they should not need replacing. They have also provided a batch of spare parts which could last us one to two hundred years."

"South Island Civilization's pure Physical Technology is so powerful... Can it actually make medicine that slows down aging?" Lu Yuan could not shake off that uneasy premonition.

"Mr. Lu, how should I put it... Many times in biology, it's a matter of luck and coincidence. If luck is on our side, we don't doubt that Earth's mother civilization can also produce this kind of drug. From its current performance, this drug is understandable within our recognized boundaries."

Although Lu Yuan still felt inexplicably worried, he really didn't understand these issues, and it wasn't good to point fingers here, so he left the research task to the experts, while taking 10 newly manufactured "D-Omega Active Potions."

Back home, relying on the Tree of Life.

Old Lu, being a bold artist, directly swallowed a pill.

He closed his eyes, feeling the medicine slowly digest in his stomach.

Over the years, Lu Yuan really hadn't aged much; his lifespan, like that of the Tree of Life, might last very long.

As long as he could survive the Epoch Disaster, even till the tenth Epoch, he would still be alive.

But some local cells still need metabolism, like red blood cells, hair, skin, etc., almost renewing every day.

After a while of patient Experience, amplifying his own perception, the medicinal effect circulated with the blood throughout his body.

That nearly dead hair on his body seemed... probably stood stiff a bit longer?

"It really extended lifespan... It also has a good effect on me..."

"Pure Physical Technology, we really have neglected it over the years."

The future of Pure Physical Technology is extremely vast, like nanorobots, nanomaterials, artificial intelligence, genetic modification, etc., only the difficulty of climbing is too great, beyond Human capability.

Lu Yuan didn't know whether this drug could be fed to Old Wolf, in case it kills him, the trouble would be huge. So he looked around, searching for Little Mirage Dragon.

"Big Golden, time for medicine!"
