After resting at home for a day, Lin Feng felt a little bored.
Lin Feng felt he could not keep letting himself go like this. He had to go out and get some Energy Points.
There was still no news of Chen Wen. Lin Feng planned to find some time after he returned to go kill him.
He acted as soon as the thought struck him. Lin Feng put a few sets of clothes into his spatial ring and headed toward an exit from the city.
A protective barrier covered the sky above Yang City. To ensure the city's safety, all martial artists had to pass through designated passages to leave.
The nearest exit passage to Lin Feng was in the west of the city.
Since it was a large exit passage, a large marketplace had sprung up beside the city gate, specializing in all the resources martial artists needed.
At a glance, Lin Feng spotted quite a few weapon shops and potion shops.
Ordinary weapons could not withstand Primordial Power.
Only weapons forged from spirit ores could withstand the ferocity of Primordial Power.
That was why weapon shops not only sold weapons but also bought spirit ores.
Crystal cores could be used to make potions, so potion shops bought mutant beast crystal cores from martial artists.
Cultivation techniques, however, were not sold.
Aside from joining martial academies, martial universities, or various organizations, the underground black market was the only place where one might obtain cultivation techniques.
Even the lowest, yellow-grade cultivation techniques were extremely precious. Ordinary people simply could not afford them.
Lin Feng had no plans to obtain any cultivation techniques, either. He intended to sell his crystal cores first, then buy a set of clothes that would not be ruined when he transformed.
Lin Feng picked a potion shop at random and walked inside.
"Sir, what sort of potion would you like?" The moment Lin Feng entered the shop, a sweet greeting reached his ears.
"I'm not buying. I'm selling," Lin Feng replied.
Hearing that Lin Feng was not buying anything, the saleswoman immediately lost interest.
Still, it was a large shop, after all, and the sales staff had some professionalism. She did not drive Lin Feng away, depriving him of a chance to show off and slap faces.
"Sir, may I ask what you'd like to sell? Our shop doesn't buy ordinary medicinal herbs," the saleswoman said tactfully.
Seeing Lin Feng's youthful face, the saleswoman did not think he could produce anything good.
"Oh, I'm selling crystal cores. I've got both Body Tempering and Qi Sea ones. Do you buy them?" Lin Feng asked casually.
"What? Qi Sea Realm crystal cores?" The saleswoman could not help exclaiming at his words.
After her exclamation, the saleswoman hurriedly covered her mouth and eagerly led Lin Feng into a private room.
Lin Feng felt a little disdain at the saleswoman's exclamation.
It's just a few crystal cores. Is that really necessary?
This saleswoman is pretty enough, but she doesn't measure up.
Still, the saleswoman could hardly be blamed for her surprise. Not only could crystal cores be used to brew potions, but martial artists could also absorb the energy within them to cultivate, so demand exceeded supply.

Especially in a small city like Yang City, hardly any Qi Sea Realm crystal cores were brought to potion shops for sale, even though theirs was the largest potion shop in Yang City.
Thus, Lin Feng, who had made a rare appearance to sell crystal cores, was personally received by the manager.
The manager was a beautiful woman in her thirties, full of charm.
As Lin Feng took out all his crystal cores, the manager tried to entice him from time to time.
The manager was only an ordinary person, while Lin Feng could produce Qi Sea Realm crystal cores. Even if his strength had not reached the Qi Sea Realm, he was surely the offspring of a Qi Sea Realm expert.
Finding a powerful partner, even as their lover, was a dream for ordinary people.
But Lin Feng truly had no interest in her whatsoever.
To Lin Feng, potions really were not much use. Their effects were not even as good as dying once.
Casually throwing away the little slips of paper the manager and saleswoman had pressed into his hand, Lin Feng left the potion shop.
