Feng Zhengyang, as he did every time, traveled through several major cities in the Cang Lei Realm with the caravan.
They sold the specialty products brought from the Demon Realm at high prices and purchased some low-priced specialties from the Cang Lei Realm.
The journey went smoothly, and they returned to the Demon Realm safely in just a few months.
The specialty products from the Cang Lei Realm they brought back could be sold at very high prices in the Demon Realm.
Feng Zhengyang followed the group, showing no unusual behavior, and acted in a proper manner.
After returning to Tianfeng City, Feng Zhengyang kept to himself, gradually reducing his interactions with others.
This Feng Zhengyang was naturally Xiao Fei, who had killed the original owner and impersonated him.
Originally, he hadn't had such an idea.
Casually killing someone, replacing them, taking over their property and women, and appropriating the fruits of another's life's work – that seemed rather impolite.
But since Feng Zhengyang was asking for trouble, after trapping him, Xiao Fei suddenly had this thought.
So, he had a clone transform into Feng Zhengyang and blend into the Tianfeng Clan's caravan, returning to the Demon Realm with them.
Another clone continued to explore the Cang Lei Realm.
In this way, he was stepping in two worlds, making it harder for him to die.
Thinking of this, his courage began to grow again.
Through Feng Zhengyang's memories, he had gained some understanding of the Cang Lei Realm.
There were not many types of life forms in this realm, and they all possessed lightning attributes.
The dominant species were also a type of humanoid creature with round, large heads, big eyes, pointed ears, and a metal horn on their heads that stood tall. They were called Lei Ren.
Xiao Fei had now transformed into the appearance of a Lei Ren, with occasional crackling arcs of electricity around his head horn.
Fortunately, he had long cultivated the Five Elements Mixed Yuan Divine Thunder, so he could also generate some lightning to impersonate them.
A while ago, Xiao Fei had passed through a Lei Ren city and settled down temporarily.
This city was inhabited by tens of thousands of people. In the center of the city was a marketplace, which was the main trading ground for the Lei Ren in the city.
Xiao Fei was currently walking down a street in the marketplace. On both sides of the street were many spiritual items intertwined with lightning.
These spiritual items with lightning attributes were rare and valuable commodities in both the Tianyuan Realm and the Demon Realm.
However, in the Cang Lei Realm, these spiritual items were just ordinary things and not very valuable.
He also saw people selling pieces of Xuan Tie Jing, a refining material that was not very valuable in the Tianyuan Realm, but was sold at extremely high prices here.
Seeing these spiritual items, Xiao Fei immediately had the idea of becoming a cross-border merchant.
Once this thought arose, he couldn't resist the urge to realize it.
He possessed the Creation Jade Disk, a great energy consumer. Although he never lacked spiritual medicine, he was always short of spirit stones.
The currency used in the Cang Lei Realm was Lei Ling Shi, which was similar to ordinary spirit stones, but Lei Ling Shi contained lightning-attribute spiritual energy.
This lightning-attribute spiritual energy could also be absorbed and utilized by the space.
Moreover, these lightning-attribute spirit stones were highly sought-after rare items in other worlds.
Many cultivators who practiced lightning-attribute techniques needed these spirit stones but found them difficult to obtain.
No sooner said than done, Xiao Fei found a place to sit down and took out several pieces of Xuan Tie Jing from his space, placing them in front of him.
Soon, many Lei Ren came to inquire about the price.
"Excuse me, how much is this piece of Xuan Tie Jing?"
Xiao Fei held up five fingers, intending to say 50 Lei Ling Shi.
However, this Lei Ren brother threw down 500 Lei Ling Shi, and without another word, took the Xuan Tie Jing and left.
It was estimated that this Lei Ren brother still felt he had gotten a great deal.
Next, Xiao Fei took out some Chi Tong and Millennium Ginseng, as well as some very ordinary spiritual items, and casually placed them on his stall.
These items were also regarded as treasures by the Lei Ren, and they were quickly bought at high prices.
By the end of the day, Xiao Fei had already earned tens of thousands of Lei Ling Shi.
He spent all these tens of thousands of Lei Ling Shi again, purchasing items that were very common and inexpensive in the Cang Lei Realm.
The items bought with these tens of thousands of Lei Ling Shi piled up in the space.
On the other side, Feng Zhengyang in the Demon Realm took out this pair of lightning-attribute items from the space.
Feng Zhengyang then quietly sold these items in batches in Tianfeng City, and it took him a month to sell them all.
This batch of goods directly brought back tens of millions of high-grade spirit stones.
The speed of earning spirit stones this way was relatively slow, far from matching the sale of Empty Spirit Medicine.
However, the space spiritual medicine carried a trace of spatial aura, which could easily expose his identity.
By trading goods between the two realms, as long as he was careful, it would not be so easy to be discovered.
For a period of time afterward, Xiao Fei continued to trade many items between the two realms.
On the Cang Lei Realm side, to avoid attracting attention, he had already moved to several different cities.
However, on the Demon Realm side, in his identity as Feng Zhengyang, he could not move around freely.
If he were to sell lightning-attribute items in Tianfeng City for a long time, the Tianfeng Clan would likely discover it soon.
After careful consideration and weighing the pros and cons, Feng Zhengyang quietly took out Patriarch Xiaoyue and Feiyu from the space.
One was a pure-blooded great demon, and the other was a human-demon hybrid. They should be able to blend in better in the Demon Realm.
It was just that the two of them had made rapid progress in their cultivation within the space, and now they both possessed Mahayana stage cultivation.
Although Mahayana cultivation sounded impressive, in this lower realm, their cultivation was actually inferior to Integration stage.
Most people who reached the Mahayana stage could only hide deeply in their caves, not daring to show their faces.
They feared that a single misstep might attract the Heavenly Tribulation of Ascension, and their tens of thousands of years of cultivation would turn to dust in an instant.
Regarding this issue, Xiao Fei had previously learned a talisman technique from Xiao Hei that could conceal a person's cultivation aura, preventing it from being detected by the Heavenly Dao.
However, such talismans that could deceive the Heavenly Dao were not easy to refine.
Xiao Fei tinkered in the space for several years, using materials from many Earth Immortal experts, before successfully refining two of them.
When he took out these two talismans, which could conceal his aura and deceive the Heavenly Dao, he felt very proud. He had essentially created something that did not exist in the lower realm.
At the same time, Feiyu and Patriarch Xiaoyue were extremely shocked. They truly were great talents!
If only they knew that there was once someone who, with a mere wave of his hand, dispersed the tribulation clouds and made the Heavenly Dao tremble.
And this person was also the "pretty boy" they thought relied on others for sustenance.
It was unknown what they would think then.
In the long years that followed, Xiao Fei continued to engage in the business of trading specialty products between the two realms.
He made a fortune, and he threw the spirit stones or Lei Ling Shi he obtained into the space for absorption.
After more than 1,000 years, the time flow rate of the space finally increased to 120 times.
At this point, the spirit stones he earned from trading in the two worlds were like a single drop in a vast ocean for the space.
To further increase the time flow rate of the space, it was estimated that he would need to empty both worlds of their spirit stones.
Or, obtaining Immortal Stones from the upper realm would also suffice.
