I, a prison guard in the Heavenly Prison, secretly became invincible thanks to the system.

Chapter 754 1. Penniless, a Hidden Dragon Emerges from the Abyss

Number Seven gave Ye Kang a meaningful look, as if he had noticed something, but Ye Kang was completely oblivious and simply said, "Congratulations on your promotion."

"You're joking, sir. It's just a different place, but we're still waiters. However, thanks to the few orders you placed for me, I've met my sales target. What would you like to do today, sir?"

Neither Qi nor Ye Kang dwelled on the matter, tacitly glossing over it.

Both of them had their own secrets that they couldn't reveal to outsiders, especially Ye Kang, who dared not disclose his true origins.

Those powerful figures who are eyeing the fragments of the Luofu Holy Sect will certainly not let him go.

He said casually, "Just browsing, preferably magical artifacts, and preferably cheap ones."

Number Seven nodded: "Of course, the magic weapon area is on the second floor, let's just go up there."

With that, Number Seven led the two into a suspended staircase made of array.

Operating under the formation, it is a blue cube that leads directly to the upper level.

Simply put, it's an elevator.

With a flash of the formation, the three of them floated to the second floor, where a dazzling array of shelves were crisscrossed, and martial artists were searching among them.

The Linglong Chamber of Commerce was not afraid of customers tampering with their items and simply displayed all kinds of magical treasures for people to choose from.

Of course, you can't try it out, and the store's prized possessions won't be inside.

Ye Kang's needs were very clear: he wanted to find the cheapest consumables.

Soon, Number Seven led him to a shelf where a dozen or so magical artifacts were displayed in twos and threes.

"The magical items here are all economical and practical, and the prices are definitely the cheapest in our store. You can buy one for only three thousand mid-grade spirit crystals."

Ye Kang glanced at them and realized they were indeed very ordinary magic weapons, probably only at the level of breaking wooden awls.

It's perfectly fine to use it as a consumable, and you don't have to worry about being scammed when you come to Linglong Chamber of Commerce, as everything is definitely genuine.

He readily agreed, "I'll take all five."

Yin Xingtang, who was standing to the side, frowned as she watched.

"Are you crazy? Are you planning to throw these things at someone?"

"No, that's not it. I've recently become quite interested in weapon crafting, so I took it back to take it apart for fun."

That reason is reasonable, and although it's a bit extravagant, it's actually quite plausible.

Yin Xingtang asked no more questions.

Number Seven, on the other hand, was overjoyed. His old customers were the best; they delivered a big order right away.

She said, "You are a first-class VIP. You will receive a discount for a single purchase of 10,000 spirit crystals or more. The total price is 15,000, but we will only charge you 13,000."

"I didn't expect there to be a discount," Ye Kang laughed. "Is Level 1 the highest level?"

Number Seven shook his head: "No, VIPs are only considered based on the amount spent. You are currently at the lowest level, and the highest level is level five."

"Then how long do I need to wait before I can level up to level four?"

"It'll be soon! As long as I spend a total of one million mid-grade spirit crystals, I can enter level four!"

Ye Kang almost vomited blood. You call this fast?

You can sell me and see if I'm worth a million.

He mentally grumbled, then said, "Don't rush to pay, take me to the materials section."

"Refining materials?"

"No, array materials, and while we're at it, let's also take a look at rare and precious materials."

"Understood, please follow me to the third floor."

Upon hearing the word "array," Yin Xingtang recalled the fear of being dominated by Ye Kang's array formations during the entrance exam. This guy not only has extraordinary talent in martial arts but is also proficient in array formations. Now he's also interested in weapon crafting. What's wrong with his brain? Has he ever learned too many different things?

Unbeknownst to her, Yin Xingtang's curiosity about Ye Kang grew stronger.

The three arrived at the third floor, which contained all sorts of materials, including those for alchemy, weapon crafting, formations, and talismans. These rare and precious materials were not categorized separately but were mixed with other materials according to their effects.

Ye Kang naturally had his own purpose, the first being array materials, something he had long wanted to upgrade.

Currently, most formations still rely on ordinary jade talismans and Moon-Entangling Heavenly Silk.

Although it can be used, its effectiveness is inevitably greatly reduced.

Especially for large formations like the Four Heavenly Demon Formation, it is almost impossible to cast it instantly with a flick of the finger.

Therefore, he urgently needs a batch of qualified array materials to reinforce his array.

Unfortunately, formations are a game for wealthy martial artists, and the materials used are incredibly expensive.

Ye Kang picked and chose for a long time, hesitated and deliberated for a while, and then reluctantly selected a batch.

It looks like it's only enough to barely set up a decent Four-Phase Heavenly Demon Array three or four times, but the total price is a whopping five thousand mid-grade spirit crystals!

With tears in his eyes, Ye Kang chose to pack the items, and then said, "The cheapest option is still the best. These are rare and precious herbs; they can have any effect, as long as they're cheap."

"completely fine!"

Number Seven was overjoyed. Big customers are so supportive; they love customers who keep buying.

Although Linglong Chamber of Commerce has a great reputation, it still needs customers to pay, so how could it possibly have big orders every day?

Moreover, she has dozens of other receptionists competing with her, so the pressure to meet her sales targets is immense.

She fully utilized her professional skills and replied without hesitation: "The cheapest of the rare and precious materials currently on sale is the Yellow-grade rare and precious material, Ghost Antelope Horn, which only costs 15,000 mid-grade spirit crystals. However, this item has very little use and can only be used for refining weapons. There are many superior alternatives, so no one has been interested in it."

"This is it, I'll take it."

Ye Kang didn't hesitate. Although he had run out of mid-grade spirit crystals, so what? Who said he only had mid-grade spirit crystals left?

"I only have 1 mid-grade spirit crystals left. I'll use the rest to exchange for payment, exchanging low-grade for mid-grade."

Number Seven seemed unsurprised by the answer, after all, the place he had stayed in before only contained low-grade spirit crystals.

They must have saved a lot, so even if the exchange rate is a bit high, it shouldn't be a problem.

Under normal exchange rates, one mid-grade spirit crystal can be exchanged for one thousand low-grade spirit crystals. That's good money exchanging for bad money, so there's no problem. But if it's the other way around, then there will be a premium.

It takes at least 1,300 low-grade spirit crystals to exchange for one mid-grade spirit crystal.

Fortunately, Ye Kang had plenty of stock, and since he couldn't use it here anyway, he simply exchanged it for usable treasures.

In the end, after a series of exchanges and payments, Ye Kang was back to being penniless.

You can't find a single word on his entire body.

In return, they received five magical artifacts, five sets of array materials, and a rare and precious treasure.

With Seven watching them off with enthusiasm, the two left the Linglong Chamber of Commerce.

At the doorway, Number Seven watched Ye Kang's retreating figure, and his expression suddenly changed.

"This guy actually managed to escape from that deadly place. He's like a dragon emerging from the abyss. There's bound to be a good show to watch in the future. Father will definitely be interested in him."

……

Ye Kang was unaware of Number Seven's mutterings; he was already eager to return and forge the Heavenly Soldier Seal.

After leaving the city, Yin Xingtang immediately said, "Alright, I've accompanied you on this journey, now it's your turn to fulfill your promise."

Ye Kang nodded: "I will never go back on my word. Tomorrow at the Martial Academy, we will have a battle duel, how about it?"

"It's a word."
