In chaotic times, one can become a martial immortal.

Lu Yuan's blood and qi surged, and his internal energy flowed like a surging river.

The skin is washed and polished again and again.

Finally, his skin began to turn red.

It wasn't the red of bloodshot veins, but rather like red-hot copper.

Even more intense pain kept coming, as if someone was scraping his body inch by inch with a sharp knife.

It also looked as if countless ants were gnawing at his skin.

Lu Yuan's expression remained unchanged, and he didn't even utter a sound.

As long as I can become stronger, what is this little bit of pain?

It's just a little bit of hardship!

"The copper sheet is done!"

Finally, Lu Yuan slowly exhaled a breath of stale air.

He raised his palm, and a wisp of internal energy flowed within it, instantly revealing faint bronze-colored patterns.

Its luster is understated, yet it exudes an indestructible texture.

"clang!"

Lu Yuan picked up a knife from the weapon rack and slashed it hard into his palm, producing a crisp metallic clang.

The sharp blade had already chipped in several places.

His hands, however, remained completely unharmed, without even a trace of white marks.

This is copper sheet, which is tougher than iron sheet and has at least two or three times stronger defensive capabilities.

He's probably so fine now that even if he stood still and let people hack at him at will, he'd be completely unharmed.

However, this is still not enough.

For true geniuses, sheet metal is merely the starting point; copper is what they truly seek.

What Lu Yuan pursued was the ultimate level of the Skin Polishing Realm: Golden Skin.

[The Complete Five Elements Vajra Body Skin Polishing Chapter (2333/150000)]

Although the maximum proficiency level has reached a terrifying 150,000, Lu Yuan can now gain more than 2,000 proficiency points every time he cultivates.

Even if you can only maintain a pace of three training sessions a day, it should take at most half a month to reach perfection and obtain the Golden Skin.

"There are only ten days left until the martial arts competition. If I want to achieve the Golden Skin level before the competition, I need to increase my training progress to five times a day."

Lu Yuan's gaze sharpened slightly as he pondered inwardly.

Although the Zhou family is now providing him with almost unlimited amounts of common resources such as meat, medicinal soup, and pills, the effects have been greatly reduced. Even maintaining the pace of three training sessions a day is extremely difficult, and he still needs the assistance of a hundred-year-old blood ginseng.

However, although some of the century-old blood ginseng is still left, there isn't much left. Even if it's all used up, it probably won't last more than a few days.

Moreover, we should keep some of this precious medicine in case of emergency.

In that case, if he wants to increase his training progress to five sessions a day, he will probably have to find a way to get more meat from exotic beasts like the Spirit Rhinoceros.

However, on the other hand, one tael of spirit rhinoceros meat costs fifty taels of silver, and a meal requires at least two taels, which is one hundred taels of silver. If one eats three meals a day, it would cost three hundred taels.

If you eat for ten days, that's three thousand taels.

Lu Yuan currently only has a little over 1,600 taels of silver, leaving him short by nearly half.

We need to find a way to make money!

Lu Yuan wiped the sweat off his body.

With his current cultivation level, earning over a thousand taels shouldn't be too difficult for him.

……

Day two.

At the enthusiastic invitation of Zheng Shuang and Zhang Yida, Lu Yuan once again visited Shiweitian Restaurant.

As always, in addition to a large table of delicious dishes, there was also a large piece of rhinoceros meat.

"Brother Yuan, let me toast you. It's an honor for me, Zheng Shuang, to have you as a friend. Cheers!"

"Brother Yuan, I, Zhang Yida, am the same!"

Of the three, Lu Yuan was the youngest, but neither Zheng Shuang nor Zhang Yida dared to underestimate him in the slightest. They even treated him with the utmost respect, calling him "Brother Yuan" repeatedly.

"Zheng Laoqi, I didn't lose to you last time, but to Brother Yuan."

"Zhang Laojiu, stop talking nonsense. I met Brother Yuan before you did. Just based on that alone, you'll always be one step behind me!"

"Impossible! If Brother Yuan is the boss, then I'm number two, and you're number three. No arguments allowed!"

"Bullshit, I'm number two!"

"Get lost, you're my second son!"

The two argued for so long that they were about to roll up their sleeves and have a full-blown battle.

Lu Yuan shook his head speechlessly, then asked, "Do you know where we can get a large quantity of exotic beast meat?"

"Although exotic beasts are easier to find than precious medicines, they are extremely difficult to hunt. Even on the black market, there are only one or two special days each month when exotic beast meat is sold in limited quantities."

"If Brother Ruoyuan had spoken up a few days earlier, my Zheng family might have been able to spare two or three catties of Spirit Rhinoceros Meat!"

"Brother Yuan, our Zhang family currently has no more Spirit Rhinoceros Flesh left!"

Upon hearing this, the two immediately fell silent and shook their heads helplessly.

Lu Yuan finally managed to speak up, but they were completely unable to help.

They have no shortage of money, but meat from exotic beasts like the Spirit Rhinoceros is hard to buy even with money.

"Brother Yuan, perhaps in a couple more days, there will be new exotic beast meat. My father said that deep in the Black Cloud Mountains, there seems to be an Ironback Bull. Quite a few experts have already gone into the mountains to try their luck. My Zheng family has also sent two guest elders at the quasi-entry level!"

Zheng Shuang suddenly thought of something and quickly said.

"Although two of my Zhang family's guest elders have gone there, I think the chances are slim. It is said that the silver-backed bull is extremely powerful. Even a master of the Transformation Realm cannot harm it in the slightest. The entry-level one is probably not that strong either."

Zhang Yida shook his head and said, "Even if we are lucky enough to find it, unless we have a real divine weapon or a powerful expert, no matter how many people go, we probably won't be able to take down that silver-backed bull."

"A silver-backed bull, a strange beast?"

Upon hearing their words, Lu Yuan's eyes lit up.

If he could hunt down this silverback bull, he could obtain over a thousand pounds of flesh and blood, enough to last him for a long time.

The fur, bones, and all of these should be enough to fetch a large sum of money.

However, the Black Cloud Mountains are extremely vast, and for him to search for that silver-backed bull is like looking for a needle in a haystack.

Therefore, he needs to cooperate with others.

"I need the location information for that silverback bull!"

Lu Yuan looked up at Zheng Shuang and Zhang Yida and said directly, "As long as you can find it, I'm confident I can kill it, and then we can split the spoils!"

"Brother Yuan, are you sure?"

Both of them looked at Lu Yuan with strange expressions.

"Um!"

Lu Yuan nodded.

With his ninth-grade copper skin cultivation level, plus the blazing sun sword energy, there shouldn't be any problems.

"I'll send people to search for that Ironbacked Bull right away. If Brother Ruoyuan can really kill it, I only need 10% of the credit!"

After saying this, Zheng Shuang hurriedly left.

"I only need 10%!"

Not to be outdone, Zhang Yida followed suit.

Lu Yuan wasn't in a hurry. After finishing off the remaining spirit rhinoceros meat and various delicacies, he left the Shiweitian Restaurant and returned to the courtyard.

"Brother Yuan, we found it!"

It wasn't until the evening of the following day that Zheng Shuang and Zhang Yida finally arrived, panting heavily.

"Walk!"

Lu Yuan didn't delay and immediately followed the two out of the city, speeding towards the Black Cloud Mountains.
