When it was actually implemented, it turned out that the time needed was much more than anticipated.

In order not to slow down his own strength and also to prevent the superpower users who followed from becoming resentful, he 'kindly' organized a 'free artifact rental' program.

The content of this program was: every day, at least a thousand first-tier artifacts would be placed next to the Safe House, free to use, and if they were damaged, there was no need to compensate, as long as they were returned the same day.

This program only operated during the city construction period and would be canceled once the city was completed.

As a result, a large group of superpower users who indeed had some resentment immediately became joyful again, even though they had already received artifacts that fully belonged to them.

But using their own artifacts was nowhere near as fun as using someone else's artifacts!

Their own artifacts were always used sparingly, for fear of accidentally damaging them, even though they knew that artifacts were not easily damaged.

However, when using someone else's artifact, they didn't feel such distress; each of them even wished to go monster-hunting whenever they had time since Lord Yang Yuan had said that there was no need to compensate if they were damaged.

Thus, even during the city construction period, Yang Yuan's personal experience was skyrocketing.

The fifth night after construction began.

It was still the same beach.

After Zhao Jiayan and Jiang Yiyi had fallen asleep in the Safe House, Yang Yuan came outside and glanced at his personal experience:

[Lv.29: 2913/768 (Upgradable)]

"It's enough; there's even extra."

Yang Yuan smiled contentedly and began to level up.

Before long, he reached level thirty, with his physical strength and neural reflexes dramatically increasing.

At this point, he sensed a constraint again.

This constraint seemed to be his own, but also like it belonged to the world.

However, this constraint did not exist for long and was immediately smashed through by his conceptual experience.

"Boom——"

His mind roared, and the feeling of a breakthrough similar to a major realm advancement resurfaced.

Although the increase was not as vast as when leveling from ten to eleven — a true major realm breakthrough — it was still significant.

For a long while.

Yang Yuan felt his energy surge upward dramatically, and his perception range also greatly expanded.

The increase in his perception felt as if the world had shrunk relative to him, or perhaps he had grown larger relative to the world.

[Lv.31: 0/4 (Not Upgradable)]

'Level thirty-one, late human level!'

Yang Yuan chuckled softly.

But this was not the end.

During this period, he had accumulated enough experience for many second-tier wooden swords, only held back because of his own level constraints, keeping the wooden swords from advancing to a third-tier.

Now, with his level sufficient, he could continue upgrading these wooden swords to third-tier artifacts.

He waved his hand, retrieving these wooden swords and upgrading them one by one.

As expected, after reaching the third tier, apart from being sharper, the swing speed of the artifact wooden swords became three times the normal rate.

Once all wooden swords with enough experience reached the third tier, his personal experience increased by more than five hundred points.

Without any pause, he continued to level up.

After a while, when the five hundred-plus points of personal experience were used up, his level directly reached level thirty-seven.

[Lv.37: 251/256 (Not Upgradable)]

Yang Yuan clenched his fist, feeling the soaring power, and revealed a cold smile.

"Very nice!"

Earth level is nothing more than level forty-one.

He was not far from the Earth level.

'The free rental program needs to be modified too; the rental artifacts will be changed to second-tier ones. I truly am a good person!' He quirked the corner of his mouth.

The next day, the city construction continued.

By this time, the city walls were fully constructed, and Yang Yuan used a printer to print numerous ancient city defense crossbows and installed them atop the twenty-meter-high city walls.

It is worth mentioning that the materials he used were scanned models of exorcism sculptures and Golden Arrows that he preserved earlier. He enlarged these models and printed them out, then used them as materials to print the city defense crossbow parts, assembling them.

Thus, even if they weren't as strong as the original versions, once they reached the artifact level, they should still possess slight evil-breaking and godslaying attributes.

Each city wall had a city gate, and atop each city wall, there were four towers. Each tower mounted a city defense crossbow and a godslaying crossbow.

After the city walls were constructed, it was time for the internal buildings.

This was the most troublesome part.

Yang Yuan patiently continued constructing, beginning with the city lord's mansion.

Inside the city, it was divided into a massive nine-square grid, with each square being a distinct district.

And the city lord's mansion occupied the central square solely.

That is, it occupied an area of 102,400 square meters, with a length and width of 320 meters each.

Yang Yuan decided to create an inner city; its interior would feature some artificial hills, pools, and pavilions.

As for the very center, a lighthouse would be constructed, with a height of at least one hundred meters.

He intended to use the Spirit Monster Core of the Drought Fiend as the lamp core, to illuminate the surrounding land with this lighthouse.

That day.

20 kilometers off the Sunshine Coast on the sea, a smooth head suddenly emerged.

This head bore human-like features, yet its eyes were round fish eyes.

A humanoid creature, five to six meters tall, looked expressionlessly at the land twenty kilometers away, where a city was being built.

After watching for a while, it silently submerged, diving rapidly underwater, and then proceeded swiftly along the seabed.

After traveling over 300 kilometers, it arrived at an ancient underwater city.
