Searching the mountain of books, peering every single of them, he found nothing that he wanted.

Moving to the next store, using the same method to persuade the owner, he still found none that he needed.

Third store...

Fourth store...

He moved to the ninth store, but there's still no luck, with the cultivation technique that has quality above ten.

Sigh*

If this place didn't have them, he should stop searching.

Standing in front of the majestic building, it makes him feel small.

'How did this building even fit in the underground.' He found it hard to believe.

The map did state that this place was selling books. Other than books, it was selling many other goods too.

Though, the primary use of this building wasn't to sell stuff. It was a battleground for entertainment.

Walking into the building, he heads directly to the reception desk. Seeing the receptionist, he frowned. It was the same woman that he met at the rip-off center.

"Oh... How are you doing? Did you find the books you needed?" The woman greeted.

"Is there any other receptionist?" Zhen Lun didn't want to confront her again. He wanted to turn back and head to another place, but this place was his last hope.

"Why? Are you shy? or would you like a fat lady to accompany you?" The woman threatened him.

"Do you have high-quality cultivation technique book?" Zhen Lun immediately gets to the point, not wanting to entertain her.

"What a boring guy..." The woman smirked. "By the way, would like to sell that girl? I'm sure that she'll fetch for a good price." She suddenly changed her attention toward Xiao Xue.

His expression went dark when he heard that. "I won't ask for the second time. Do you have a high-quality cultivation technique book?"

"Oh, What are you going to do about it? Did you know what place you're at now?" The woman smiled at him.

The atmosphere between them got tenser and tenser. The woman didn't look like she was messing around either.

...

...

"Hahaha." The woman abruptly laughed. "Nevermind what I said, you are an amusing man. What was it again? Cultivation technique?" The woman handed over him a list of paper.

"Those are the list of our writer. If you want the best quality, I'm guessing you want to go for the one at the top. Depending on which writer you choose, the price is different."

'...' It took him a few seconds to realize that, he was being toyed by her.

Zhen Lun has prepared himself to fight and was ready to engage.

The fight between him and the whole black market people, even without fighting, a blind person will know which side will win.

"If you're not satisfied with them, you should head to the capital city. We also established our business under it too." The woman confidently revealed it to him.

'Under the capital city?' Does the emperor not know about it? Why did she tell me?'

"For now, give me one of the most expensive." Zhen Lun handed over his gold.

He wanted to confirm if the book has quality ten or not. The book cost two hundred golds! When he offered one hundred gold for one book, he was just bragging. He wasn't entirely serious.

If he found the book at one of those shops, he would try to negotiate with the owner.

After receiving the book, the woman gave him the book. "Here you go."

Zhen Lun received it and instantly examined it with his system. His eyes brighten as he finally found the one he needed.

[Book of Mastery, Cultivation Technique Book] (Quality:11)

The book only has eleven quality. They're not much, but he would gladly consume it. "How many of these are in your stocks?"

"We have a hundred of them, would you like all of them?" The woman knew that he was extremely interested in the book. "If you take all of them we would give you some discount."

"How much?" He wanted to know the price first. He does have gold, but it was not unlimited.

"This much." The woman pointed out four of her fingers.

"Four thousand?"

For once, he thought that the woman wasn't that bad. If he bought them in huge number, there will be such a huge discount but what comes out from her mouth next made him infuriated.

"Forty thousand."

"What?! I thought it was 200 gold each?" Zhen Lun wasn't going to fall for her tricks anymore. "I would rather buy it from the capital city."

Hearing that, the woman expression instantly changed. "Twenty-five thousand that's the last price I could give, take it or leave it."

Even though the price was decreased, he still didn't have enough golds to pay her.

"Can I pay with items? How much does this sword worth?" Zhen Lun handed the bronze sword.

"Master, you're going to sell your sword?" Xiao Xue asked. She suddenly spoke when it was about the bronze sword.

Looking at her sullen expression, he realized he has done something wrong, but he wasn't sure what was it about. "W-what's wrong?"

"It's obviously not the sword." Xiao Xue replied with a sulky face.

"T-this..." Zhen Lun immediately returned his sword. "Nevermind the sword. How about this liquid?" Zhen Lun grabbed out a small health potion instead of basic health potion. He only sells this because there was no choice. This is only because Xiao Xue is pouting.

"What so special about this liquid?" The woman asked. She has never seen the red liquid before.

"It can heal people external or internal injuries and as well as regenerate a limb." Zhen Lun bluntly said what it is capable off, just from his description, he knew the woman should be shocked.

"I see." The woman was unconvinced with his words and merely nodded her head. "But we're not accepting it."

"Why?" Zhen Lun was puzzled.

"First of all, do you think I am that stupid? A liquid that can regenerate limbs? Second of all, unless you can prove it there's no way I'm taking it." The woman pointed out the reasons.

'Can he prove it? If he could, this means that he still has more of them. If this liquid is really what he said, I don't think he will escape from here alive.' The woman stared intently at him, waiting for his responses.

"To be honest, I was a bit exaggerating when I say it could regenerate limbs but it can heal external injuries and internal injuries." Zhen Lun didn't grab a new bottle out as he knew that It will cause an uproar.

Making a small injury in his hand, he drips the red liquid on it. The moment the liquid touched his injuries, it healed it instantly without leaving a trace or scar.

"Do you have more? One bottle is not enough." The woman asked. trying to get more information if she could.

"Then, I'm not selling this anymore." Zhen Lun quickly grabbed back his potion.

The woman quickly stopped him. "Okay, just because this is something we never saw before, we will be generous."

"Deal." Zhen Lun gave her the potion and golds. He didn't give all his gold, he left some for himself. After a few minutes, he received his books. He then stowed them inside his inventory and was ready to leave this place already.

"Don't be too hasty, there are many things that you have yet seen, Why don't you come inside?" The woman persuaded him.

"No thanks, I don't have golds anymore." By pointing out that he is broke, the woman should lose her interest toward her.

"Please visit us in the capital city!" The woman cheerfully said.

Only if he's strong enough he'll visit the black market again. He swore he will return this debt.

...

...

"Master, Do I need to bring him back?" A hidden assassin asked the woman with whispering.

"There's no need anymore. I think we'll meet again. Right?" The woman devilishly smiled as Zhen Lun left.

-----

They have returned to the surface, he miraculously avoided a disaster that was about to befall him.

Sigh*

"We should return to the inn." He said relievedly. With Xiao Xue, they walked back to the inn. They then rested for a few hours before they departed on their journey.

During that time, he also consumed the book he received.

[Cultivation Technique leveled up!]

[Cultivation Technique leveled up!]

[Progress 1%]

...

...

In a few hours, They passed two cities without needed to stop. Blacky has gotten used to running a few hours straight.

After passing another city, they finally can see the capital city. They could see the capital city. Even they're a few kilometers away, they could still see the city.

"Blacky, return to my shadow. You can rest now." They're near their destination, few kilometers shouldn't be a problem for them.

In another few hours, they arrived in front of the capital city, the most flourish city, Golden City.

The wall that surrounded it was four times larger than Xin Hai City. Other than that, It was also engraved with runes.

Entering the city was also troublesome. There's two way to enter. The first way was to pay a large amount of gold. Secondly was to use an identification token, obtained from the emperor. The token will allows you to enter and exit the city freely, without needing to pay gold.

This city are very strict with their security, they won't let any suspicious people enter.

In other words, everyone in this city has a strong background. They're either rich or influential in politics.

Arriving at the gate, Zhen Lun presented the token that he received from General Shui. He received back then when he was about to leave the mansion. Thankfully, General Shui remembered to give the token to him or he couldn't enter the city with the current gold he has.

The payment to enter was either two gray spirit stone or ten thousand golds.

Storming in was impossible with the top-notch security that this city has. The guards that were guarding the gates are transcendent mortal. For a transcendent mortal to be a mere guard, you can imagine what kind of people is waitting for him if he dares to make an uproar.

Strolling in the city, you could see that the people here are extraordinary. The clothes they're wearing aren't normal. You could sense that it was similar to a spiritual weapon. They're wearing spiritual armor as normal clothing.

-----

"Brother Shao, who are you waitting for?" A girl asked. She's Shao Wei fiancee, Zhang Xinyi. She also attended the Golden Sky Academy with him.

"He's someone that I looked up for." Shao Wei replied earnestly. Since he was a kid, he has been looking up to him. His father would always compare him with Zhen Lun that sometimes it's hard to suppress his jealousy.

But after looking at how hardworking he is, Shao Wei definitely understands why his father always putting Zhen Lun and him, side to side.

'I've heard the tournament over his side is over. If he wanted to attend this place, he would arrive either today or tomorrow.' Shao Wei was excited.

"What kind of person he is?" The girl asked.

"Hmm... weird, boring, dull?" Shao Wei pointed out a few things about Zhen Lun.

"And you looked up to a weird, boring and dull person?" The girl looked at him strangely.

"That's just the negative one. I don't know much about him, We only met once and that was when I was a child, but somehow his face and actions were vividly remembered by me." While Shao Wei was explaining weird things about his childhood memories, the girl suddenly went up close and kissed him on the cheeks.

Shao Wei immediately flustered. "W-why did you do that suddenly!" He blushed as he holding the spot that was kissed.

Seeing that he was still embarrassed about it, she was relieved. "Nothing..." She whistled.

She literally thought that Shao Wei liked Zhen Lun. It was not her fault for thinking that far ahead. Why would he remember clearly about someone that he only met for once? Isn't that love at first sight?

"Anyway, the good sides of him is that he has a charismatic aura." Shao Wei was still blushing.

...

"Is it that guy, you're talking about?" Xinyi said as she pointed to a guy that was being chased by some people.

'Hm?' Shao Wei squinted his eyes, trying to confirm it. It turned out to be true.

'What the heck did he do to be chase by a bunch of people?' Shao Wei eye's twitch as he looked at the current scene.
