Cosmic Crystals?!

When Zhang Dong sold goods at the Treasure Market, he had no safety concerns. The entire market was covered by an array. Anyone who dared harbor evil intentions would be met with its boundless might and slain.

An ordinary Chaos Realm expert would probably be reduced to ashes in an instant.

Taking out a full kilogram of Fermo Venom, Zhang Dong said softly, "This item is called Fermo Venom. Just one drop can kill a God Level expert."

The Fermo Venom, notorious throughout the Primordial Universe, sat in his hand like an ordinary lump of purple liquid.

Most God Level experts could be killed with just 0.0001 grams. Even the slightest touch would cause their true body's divine core to collapse.

The burly man glanced over casually and instantly analyzed the Fermo Venom's composition, its lethality, and how it should be used.

He could even modify the Fermo Venom to make it less troublesome to use.

In the Primordial Universe, Fermo Venom had to touch an Immortal Divine Body before it could take effect. It also needed a carrier: it had to be smeared on a weapon and used to cut an opponent's divine body.

"Hmm, this venom is rather ordinary, but I've never seen its ingredients before. That's somewhat interesting." The burly man pondered for a moment, then set a price for the Fermo Venom.

He couldn't be bothered with venoms that could kill ordinary gods. He would simply offer a little money and buy them.

However, the ingredients used to make Fermo Venom could only be found in the Primordial Universe of this Source World, the Origin Continent. They didn't exist on the Boundary Heart Continent.

Each Source World had different rules, so the materials it nurtured and other such things varied as well.

"One thousand Xiafeng Coins. The price is non-negotiable," the burly man said. "I'll pay the same price if you want to sell more later. I'll buy all the venom you have."

The common currency used for trade across the Boundary Heart Continent was Cosmic Crystals.

However, many World Gods like Zhang Dong, lower-level gods, and even higher-level True Deities didn't have a single Cosmic Crystal to their name.

The complete Nanyun Saint Twelve Forms cost only one hundred thousand Cosmic Crystals.

That was the cultivation method created by the overlord, the Nanyun Kingdom Lord, and it cost only one hundred thousand Cosmic Crystals to learn.

So each kingdom also had a lower-tier currency for gods and World Gods to use. Xiafeng Coins were used in the Xiafeng Ancient Kingdom.

Hearing the price, Zhang Dong was overjoyed. One thousand Xiafeng Coins—far more than the Fermo Venom had been worth originally.

It seemed the burly man was interested because the ingredients in the Fermo Venom were unfamiliar to him.

A kilogram of Fermo Venom was worth three trillion Hunyuan Units.

All the weapons that sum could buy were useless to Zhang Dong. More precisely, once he reached Venerable Level strength, Hunyuan Units would no longer have any value to him.

But one thousand Xiafeng Coins could buy a complete set of World God weapons, and might even be enough for a somewhat inferior True Divine Artifact.

Most importantly, the burly man had said he would buy as much as Zhang Dong had. He could gather Hunyuan Units and sell all kinds of venoms in bulk to his race.

"The venom's fine, but I have another weapon here. Could you take a look and see if I can sell it?" Zhang Dong took out an E9 Laser Gun.

There were very few things from the Primordial Universe that could be sold here. Things like spaceships and even ordinary flying palaces were useless if brought over.

Only those in the True Deity Heaven and Earth Realm could fly. Spaceships and ordinary Heavy Treasures couldn't fly at all—they were nothing but scrap metal.

As for energy weapons, such as Fire God Source Crystals, under the restrictive rules of the Boundary Heart Continent, their explosion radius might not even reach a meter.

Using them to replenish energy would be like taking an ordinary breath. Who would pay for that?

After thinking it over for a long time, Zhang Dong decided to try selling the E9 Laser Gun. It didn't matter if he couldn't sell it; it had been cheap anyway.

The burly man took the laser gun, which was about three meters long from end to end, and examined it closely for a long while before speaking. "This weapon's design is rather ingenious, but it stores very little energy and only has God Level power. The design is worth something. I won't cheat you: one Cosmic Crystal. But you have to swear that you won't sell one to anyone else."

"?!"

Zhang Dong stared at him, dumbfounded. He hadn't made a face like this in a long time—not since he'd begun cultivating. His expression was full of disbelief.

He even wondered if he'd misheard.

One Cosmic Crystal?!

What an outrageous price!

The E9 Laser Gun was nothing compared to the Fermo Venom. A kilogram of Fermo Venom could buy an enormous number of E9 Laser Guns, yet the difference in price was astonishing.

Cosmic Crystals were far more valuable than Cosmic Sand back in his home, the Origin Continent.

On the Origin Continent, fifty billion Cosmic Sand wasn't enough to buy even a Divine King First Realm weapon. Meanwhile, a Universe God's secret treasure on the Boundary Heart Continent generally cost between five and ten billion Cosmic Crystals.

One Cosmic Sand was equivalent to ten thousand Chaos Crystals, while maintaining a True God Level subordinate for an Era cost only three Chaos Crystals.

Whoosh—

A dazzling Cosmic Crystal landed in Zhang Dong's hand. It glimmered from within, as if it contained a miniature universe—a vast, immeasurable store of energy.

The combined wealth of every True Deity and Universe Master in the entire Cosmic Sea couldn't begin to match the value of this single Cosmic Crystal.

If Zhang Dong took it to the Origin Continent to hire True Deities, he could easily hire ten thousand at once.

If there were a slave market, he could even buy a True Deity slave to serve him. This enormous fortune—a Cosmic Crystal worth more than the entire Human Race—had been exchanged for an E9 Laser Gun?

Zhang Dong felt as if he were dreaming. The Cosmic Crystal in his hand still gleamed, its brilliant light illuminating his face.

"Don't just stand there, kid. Hurry up and swear," the burly man said sternly. "My name is Qu Yu."

Once an oath was made, it created a karmic bond. Powerful experts could avoid the consequences of such karma, but it would still affect their Dao hearts.

But Zhang Dong was merely a World God. If he dared break his oath, the backlash from the immense karmic force would be enough to kill him.

Even if he cultivated to the True Deity level one day, Qu Yu could still use that karma to kill him with ease.

"I swear that I sold the E9 Laser Gun to Qu Yu today, and even if I have another one just like it in the future, I won't sell it to anyone else," Zhang Dong said obediently.

One Cosmic Crystal for an E9 Laser Gun.

It was like getting a Supreme Treasure for one Black Dragon Coin.

What he didn't know was that countless universes existed within the Boundary Heart Continent, but almost none of them studied technology.

The various kingdoms deliberately guided and influenced them, so the countless universes still focused on cultivation systems. Even where technological products existed, they were nowhere near as advanced as those of the Primordial Universe.

The Origin Continent had Mechanical Flow and all kinds of advanced technology, so the lower-level Primordial Universe also had advanced technology.

Qu Yu naturally saw the value in the E9 Laser Gun, since he had never seen a weapon designed like it before.

Its power didn't matter.

If he could use the E9 Laser Gun to develop similar technological weapons—nothing too powerful, just something capable of instantly killing True Deities—and sell enough of them, the rewards would be far more than a single Cosmic Crystal.
