May I seek good fortune and avoid misfortune, and live a long and prosperous life.

Li Heng carefully flipped through a few pages. With his current peak Grandmaster level and extremely profound martial arts experience, he found that this technique was indeed not made up, but was full of valuable information!

"This middle-aged man is probably not lying; it was likely left behind by Yan Tiannan, the number one swordsman of the martial arts world eighty years ago. This is exactly the secret manual I urgently need. However, I can't reveal how much I want this manual, lest the stall owner find out and immediately raise the price."

Li Heng pretended to be regretful and put the wedding dress cleansing technique back in its original place.

Seeing Li Heng's expression of having some ideas but then shaking his head, the middle-aged man quickly stepped forward and struck up a conversation:

"How should I address you, sir? Are you interested in this cultivation manual? You have excellent taste! This manual is no ordinary one; it's a family heirloom, extremely rare to find outside!"

This manual, "The Wedding Dress Cleansing Technique," was written by Yan Tiannan, the greatest martial arts master of eighty years ago. Yan Tiannan was a legendary figure! It is said that he successfully advanced to the legendary Celestial Realm, and then disappeared from the martial arts world without a trace, as if he had vanished into thin air.

This martial arts manual was written in his later years, and its value is extremely high! If you are interested, I can sell it to you cheaply, for a fixed price of one thousand taels of silver. What do you think?

Li Heng listened slowly as he finished speaking, then smiled and said:

"Don't try to fool me. Even if this manual of yours is really written by Yan Tiannan, its value is limited. The threshold for cultivation is the peak of the Grandmaster level, and you have to disperse your power before you can cultivate it. How many peak Grandmaster martial artists are there in the world?"

They are all renowned figures, who would be willing to waste their cultivation and start over? Besides, time waits for no one. If they were to start cultivating again, it would take thirty years to reach the peak of the Grandmaster realm, which would already be considered the work of an unparalleled genius. And even then, there's no guarantee they could regain their cultivation. Who could afford to waste such a long time?

Don't joke around, this is just a useless book. But I've always liked collecting rare manuals from famous masters. Your manual has limited martial arts value, but it still has some collectible value.

"Here's what I'll offer: six hundred taels of silver. If you're willing, we can trade now. If not, you can leave it to rot. I'll go look elsewhere."

After saying that, Li Heng made a gesture as if he was about to go and check out other stalls.

The middle-aged man quickly weighed the pros and cons in his mind, and he also admitted that Li Heng was telling the truth.

At this moment, some martial artists nearby, seeing that Li Heng wanted to buy that useless martial arts manual, pointed and whispered among themselves:

"Looks like a sucker is about to be fooled. The so-called peerless martial arts technique of the number one hero in the martial arts world is actually a piece of utter garbage. If it were really valuable, it wouldn't have been sitting there for more than ten days without a single master willing to buy it."

Hearing these rumors, the middle-aged man blushed. Although he was not skilled in martial arts, he believed in his heart that this technique was indeed useless and that people were right to call it trash.

So he was even more eager to sell the manual. Anyway, he had other copies at home. After selling this one, he could sell the others later. He wasn't afraid of not finding any suckers to take advantage of him.

He feigned a pained expression and sighed, "Since you are so sincere, I will do you a favor and sell it to you for 600 taels of silver! I hope you will take good care of this technique and not lose it."

Li Heng nodded, wearing an expression that suggested he had been taken advantage of.

"Sigh, well, it's rare to see Yan Tiannan's cultivation technique. I've been itching to get my hands on it for so long. I've always wanted to collect his techniques but never managed to. Although it's a bit useless, it still fulfills my wish! Six hundred taels of silver, right? You wait here."

After saying that, Li Heng took out six silver notes from his sleeve and handed them to the middle-aged man.

"This is the largest money exchange in Kyoto, Jufu Money Exchange's banknotes, which can be exchanged all over the country! Each note is worth one hundred taels, and there are six in total. Take a close look."

The middle-aged man took the silver note and examined it carefully. He then smiled with satisfaction and said:

"You're very generous. This is indeed a bank note from Jufu Money Shop. You can take this manual with you. This way, we'll consider the money and goods settled, and we won't accept any requests for a refund later."

"Of course, the money and goods have been settled, so there's no going back on my word. Do I look like the kind of shameless scoundrel who breaks his promises?" Li Heng put away the "Wedding Dress Cleansing Technique" and asked the other party in return.

"Haha, you seem like a very straightforward person, so you certainly wouldn't be that kind of person," the middle-aged man said with a fawning smile.

Li Heng nodded, waved to the middle-aged man, and then left the stall to walk to the next one.

Ultimately, after Li Heng found nothing else of use to him, he left the black market.

While in the black market, several martial artists secretly followed Li Heng, but Li Heng kept quiet and acted as if nothing had happened.

After leaving the black market, Li Heng slowly returned to his small clinic.

Then, once everything is prepared, wait patiently for the other party to come to you.

As night fell, around 11:45 PM, a sudden gust of wind blew past the clinic.

Then, three dark figures quickly scaled the courtyard wall.

Li Heng, dressed in black and masked, sat upright in the dark hall of the clinic, having already noticed all of the other party's movements.

The three shadowy figures first searched the front hall, but finding no one, they immediately moved towards the back hall.

When they reached the back hall, it was pitch black. One of them took out a tinderbox and lit the candlestick.

The hall was instantly illuminated again, but the three of them were stunned and dumbfounded.

Why is there a masked man in black in the hall? Could he be one of my accomplices?

Wait a minute, there are only three of us. Could it be that we're also here to rob the owner of the clinic?

"Who are you, sir? Why don't you state your name? This big fish was first targeted by the three of us brothers. You took it without asking. Isn't that a bit against the rules of the martial arts world?" the leader said with dissatisfaction.

Li Heng sneered, "So you all see me as a big fish? I wonder where you get the courage?"

"Oh, so you're the big fish? You're dressed quite shadyly. Since you've admitted it, hand over all your money. If you satisfy us brothers, we might spare your life."

All three of them were first-rank martial artists, while the person opposite them had no aura at all. Even if he wasn't an ordinary person, he was still a third-rate martial artist. With three people against one, their advantage was too obvious!

"Want my money? Let's see if you have the ability," Li Heng said with a playful smile.

"Looks like you're going to have to suffer the consequences, brothers, let's go!"

After saying that, the three of them attacked together, each using their signature move.

Strategically despising the opponent while tactically taking them seriously is the key to their success in navigating the world for over a decade, "fishing" countless times without ever failing.

Even a lion uses its full strength to hunt a rabbit!

Just as they attacked and were within five centimeters of Li Heng, an invisible energy shield appeared. Their attacks not only failed to break through the shield, but were instead blasted away by a rebounding force.

It's as if all three of them landed their full-force attacks on him.

All three collapsed in the hall, their throats filled with a sweet taste, and they all vomited blood.

"How...how can you be so strong? Who...who are you?!"
