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

Xie Yuan scratched the back of his hand and chuckled dryly, "My dear grandson, since you've agreed to help me unconditionally this once, then go ahead and do it without worry. I'll be there for you to the end."

Moved, Ye Kang quickly cupped his hands and said, "Thank you, Third Grandfather! I don't mean to make things difficult for you, but this item is very important to me, and I have no choice but to take the risk."

"I am naturally aware of Yin Bupo's infamous reputation. His powerful martial arts, passed down from the previous dynasty to the present, have been coveted by countless people. It is understandable that you have such thoughts about it."

Ye Kang bowed deeply.

Actually, Yin Bupo's martial arts skills are no longer important; the key is those 30,000 comprehension points!

Ye Kang still has 10,000 comprehension points left. If he adds another 30,000, his Imperial Supreme Heaven-Reaching Technique can advance even further. He really cannot give up.

The two continued to watch the auction.

By this time, more than a dozen treasures had been auctioned off, with fierce competition in most cases, but all were limited to the first and second floors.

The experts in the third-floor private room have remained silent so far.

Soon, the next item was brought up for auction.

The red cloth was lifted, and a piece of parchment lay quietly on it.

Master Huyan smiled and said, "This item was obtained by a river pirate by chance. It was a family heirloom of a wealthy merchant. We have studied it for a long time and finally determined that it is a treasure map, marking the location of a treasure plant."

It turned out to be a treasure map. Immediately, someone on the first floor shouted, "Master, who dares to bid on a treasure map that is so elusive?"

Master Huyan smiled and said, "That's not right. I sent people to investigate. The location of that precious plant is very likely a Crimson Sun Fruit that is about to ripen."

"This precious plant is extremely rare in the world. It is a rare body-tempering plant that greatly helps physical cultivation. It is a truly top-grade precious plant! Starting price: one thousand taels!"

When this statement came out, everyone was lost.

“Old man Huyan, since this precious plant is so valuable, why don’t you go and get it yourself?”

"What this gentleman says is absolutely right. Wouldn't it be wonderful if Master Huyan himself ate the precious plant and tempered his physical body?"

Faced with the doubts of the crowd, Master Huyan smiled and shook his head.

"I would love to have it too, but wherever the treasure is, there must be powerful demons guarding it. I am too old to risk my life."

The crowd erupted in another uproar.

"I see. If even Master Huyan doesn't dare to go, wouldn't it be suicide for us to go?"

"Although this precious herb is excellent, one must be alive to consume it. I will now offer it to you all."

For a moment, no one made a bid.

A moment later, a window in one of the private rooms on the third floor suddenly opened, and a deep, aged voice rang out from inside.

"This item is quite good. If no one else makes a bid, it will be mine."

The voice was domineering yet languid, as if the speaker didn't care at all.

The audience members all lowered their heads, not daring to speak.

Everyone has connections and already knew that several important figures were attending the auction.

The one who just spoke was one of them.

The Golden-Robed Ancestor of Jinxiu Pavilion.

Who would dare to compete with him?

After waiting for a while, there was still no sound. Just as Master Huyan was about to make a decision, Ye Kang's voice came down at the same time.

"I want this."

Immediately, countless people looked up and stared, many of them recognizing the voice.

Isn't this the same boy who beat Yan Ruitu to a pulp on the death stage?

This guy is too audacious. Yan Ruitu is one thing, but you dare to touch what the Golden-Robed Ancestor has his eye on?

Are you here specifically to oppose the strong?

Ye Kang was also quite helpless about this.

There's nothing I can do; the thing I like is also something someone else likes at the same time.

Leaving aside the fact that this treasure trove is guarded by demons, most of whom have never eaten humans, they are of little use to Ye Kang.

But Ye Kang really wants a precious plant that can enhance the physical body!

He now possesses the Demon Body Refining Technique, which specializes in refining the physical body, making him practically a half-body tempering martial artist. If he can consume the precious plant, it will definitely allow his physical body to advance even further.

The situation reached a stalemate for a moment.

Suddenly, the Golden-Robed Ancestor let out a hearty laugh.

"Since you want it, young friend, then I will grant it to you."

After he finished speaking, the window closed automatically, as if nothing had happened.

Everyone was amazed again.

I never expected that even the Golden-Robed Ancestor would give this young man face. Just who is he?

There was a minor incident, but it didn't cause much of a stir, and the auction continued.

Soon, a martial artist brought up a box containing parchment. Master Huyan had said that Ye Kang could choose any item to take away without paying, which was equivalent to getting a treasure map for free.

He took it, glanced at it casually, and then put it away.

Xie Yuan, standing to the side, looked at Ye Kang without saying a word, but his eyes were full of strangeness.

Why is this kid interested in both demons and body tempering?

Can you learn it all?

His doubts didn't last long, because soon, Master Huyan clapped his hands and brought out the last item for auction.

All the martial artists opened their eyes wide and craned their necks in anticipation.

Master Huyan smiled mysteriously and said loudly, "The last item to be auctioned tonight also comes from the canal pirates. This item has been buried at the bottom of the canal for a hundred years. It is truly a blessing for the martial arts world that it has seen the light of day today!"

Someone impatiently asked, "Old man Huyan, stop being so mysterious, what exactly is this thing?"

Master Huyan laughed and said, "This is a martial arts manual, but its owner is somewhat different. He is Yin Bupo, a giant of the demonic path from the previous dynasty!"

"hiss……"

Countless people were shocked and horrified.

Although Yin Bupo has been gone for a long time, his name is still widely known.

He betrayed Buddhism, stole books to master demonic arts, and slaughtered his way across the world... These deeds are the envy of all martial artists.

Especially among these bandits and thieves, many of whom regard Yin Bupo as their spiritual idol, how could they not be excited?

However, they all knew their place and that they were absolutely not qualified to film such things, so they all looked up at the private rooms on the third floor.

Sure enough, the Golden-Robed Ancestor was the first to burst into laughter.

"Excellent! Excellent! Excellent! It was worth the wait. Jinxiu Pavilion is willing to pay a hefty sum to acquire this secret manual!"

No sooner had he finished speaking than a sharp blade of energy slashed through the air.

In the private room next to the Golden-Robed Ancestor, the window shattered, revealing a weathered swordsman.

“Old man in golden robes, if you want to take the manual, you’ll have to ask the sword in my hand for permission first.”

He drew an ancient, long sword; its cold gleam sent chills down one's spine.

He held the knife only on his left arm; his right arm was empty, with only a section of bare sleeve.

"Duan Hong, the One-Armed Swordsman!"

Numerous exclamations rang out, and Ye Kang also looked at the weathered swordsman.

As expected of a seventh-grade innate master, his mere presence was enough to make it hard for people to breathe.

Upon hearing this, the golden-robed patriarch's expression changed instantly, and he sneered, "Brother Duan, what do you mean by this? Do you intend to rob me by force?"

Duan Hong didn't speak, but simply picked up a stack of gold pieces with one hand and said, "It's true that Jinxiu Pavilion is rich, but I'm not all alone, so I'll have to take a gamble."

The gold flakes emitted a dazzling golden light, attracting the attention of countless people.

The old patriarch in golden robes immediately turned pale, and powerful true energy enveloped him.

"Duan Hong, watch your words, or you'll lose your last arm too."

The true energy shot out and collided with the sword's momentum, causing the entire pavilion to shake violently.

Ye Kang couldn't help but feel a little alarmed.

A seventh-grade combat power is not even in the same league as a sixth-grade one!

At the same time, a sword light suddenly appeared, flying out from the last private room, directly shattering the golden robe's true energy and Duan Hong's sword momentum.

Ye Kang asked in surprise, "There are more experts?"

Inside the private room, a Taoist priest with an expressionless face slowly rose. His blue Taoist robe was spotless, his hair was casually draped, and he held only an unsheathed ancient sword in his hand.

"Did you all enjoy your performance?"
