High-level martial arts: Contract cashback, invincible starting from the Zerg.

A few days later, after receiving the information that he had been assigned a mentor at the Martial God Palace, Chen Feng went to the Martial God Palace again to report for duty.

However, in the corridor of the Martial God Palace, Chen Feng ran into his mentor, Yu Qian.

It was as if he had been waiting here for Chen Feng all along.

"Chen Feng".

Yu Qian was dressed in a loose brocade robe with a heavy money bag hanging from his waist, looking almost identical to the clothing worn by the Dasha people hundreds of years ago.

At this moment, Yu Qian lightly twisted a lustrous ancient coin with his right hand, glanced at Chen Feng sideways, and then put on an extremely unreadable smile. His tall and stout body became even more hunched.

"My disciple Su Qingyuan said you are a promising talent, so I'm taking a look here to test my beloved disciple's judgment."

Chen Feng still had some doubts about Yu Qian's motives, but the aura of the Desolate Rank expert was so imposing that Chen Feng could only bow respectfully.

"Chen Feng has met with mentor Yu Qian."

As they chatted and laughed, the mysterious coin on Yu Qian's fingertip spun even faster, making a soft "ding-a-ling" sound.

"No need for such an honor," Yu Qian said with a slightly lazy smile, but her eyes lingered on the location of Chen Feng's Vajra Core.

"Su Qingyuan has always had a good eye. For her to praise you as a promising talent, you must not be mediocre."

As he spoke, Yu Qian suddenly stopped turning the ancient coin and then threw the lustrous coin directly at Chen Feng.

Chen Feng quickly caught the ancient coin.

However, the moment his right fingertip touched the coin, a warm and mellow spiritual energy instantly flowed into his body through his fingertip, dispelling the fatigue from his days of travel.

This seemingly ordinary, lustrous ancient coin is far from simple!

Although the ancient coin in his palm was as light as a feather, it subtly exuded a sense of profound weight. As Chen Feng caressed it with his fingertips, he could clearly feel that the coin seemed to contain some kind of mysterious rhythm, trembling gently with his breath.

Before Chen Feng could think further, he felt a slight movement in the ancient coin in his palm.

Immediately afterwards, the ancient coin vanished from his hand.

When Chen Feng looked up at Instructor Yu Qian, he discovered that as the light shifted, the coin in his hand had returned to Instructor Yu Qian's hand, forming an energy barrier radiating mysterious energy.

"This..." Chen Feng's gaze was fixed on the floating ancient coin, but his heart began to pound.

The fact that the coin disappeared from his palm and then reappeared in Yu Qian's hand in an instant was definitely not an ordinary trick, nor was it a simple illusion.

It's not a physical spatial transfer!

Combining the characteristics of the ancient coin that Chen Feng could perceive—it could be used for both offense and defense, could traverse the void, could condense an energy barrier with a thought, and could cross mountains and rivers with a single turn.

This is no ordinary ancient coin; it is clearly a powerful spiritual artifact that can kill or protect its master!

At this moment, Yu Qian seemed to have seen through Chen Feng's thoughts, and the smile on his lips deepened, but he still carried a hint of nonchalance.

"Don't overthink it. This thing isn't some kind of treasure; it's just for testing your reaction. It's alright, not too weak. At least it can withstand the training intensity of my disciples."

Yu Qian paused for a moment, then reached out and patted the money pouch at his waist.

The sudden "clattering" sound suggests that there are at least a hundred such ancient coins in Yu Qian's possession.

"However, let me make this clear from the start: there are rules regarding my use of spare money to train disciples."

Seeing that Yu Qian not only possessed combat power at the Desolate Rank, but also had a bag of powerful spiritual artifacts protecting him, his combat power could be said to crush Chen Feng by several major ranks.

Chen Feng finally bowed sincerely and said, "Please give me your guidance, Instructor Yu Qian."

"Everything is about exchanging benefits. I can teach you, but the reward you give me must be greater than this amount, otherwise there's no point in talking."

At this moment, Yu Qian held up five fingers and said loudly.

"Is it 500,000 in cash?" Chen Feng asked with a hint of doubt.

"A little less."

"Five...five million?"

"That's about enough. If you think the tuition is too expensive, you can pay 500,000 first. Otherwise, you can find another tutor." After saying that, Yu Qian turned and left.

The money pouch at his waist clanged incessantly.

Chen Feng stood there, watching Yu Qian's plump back as he swayed his heavy money bag.

He subconsciously clenched his right hand, his fingertips still feeling the warm and profound touch of the ancient coin, and even the meridians in his body, which had been nourished by that spiritual power, still radiated a faint warmth.

However, the tuition fee of "five million" left Chen Feng speechless for a moment.

Five million?

Even though he fought his way through countless battles as a demon slayer, he only managed to accumulate a little over a million dollars in cash in five months.

If it were anyone else, they would probably have already cursed him as a "greedy old devil" and turned around to seek refuge with other tutors who charge low fees and have low barriers to entry.

However, through repeated sorting of his thoughts, Chen Feng gradually calmed and balanced them, eventually transforming them into a clear and enlightened understanding.

Before he came to the Martial God Palace, he had already thoroughly investigated the backgrounds of all the registered instructors in the palace.

The Martial God Palace is one of the essential channels to reach the pinnacle of martial arts in the Great Xia Kingdom, and the instructors stationed there are all giants in their respective fields.

The two top-ranking instructors of the palace, although legendary supreme experts, have extremely strict requirements for accepting disciples—they only accept those with Heavenly Rank cultivation, and ordinary geniuses don't even have the qualifications to stand in front of them and introduce themselves.

As for Chen Feng, he hadn't even touched the threshold of the Heavenly Rank yet, so he was probably even worse than those two big shots.

As for the other instructors at the Martial God Palace, they were either mediocre in their cultivation and hadn't produced many outstanding disciples after decades of teaching; or they were arrogant and picky about family background, aptitude, and connections.

This mentor, Yu Qian, was the most out-of-place oddball in the entire Martial God Palace.

He consistently ranks among the top three authoritative mentors in the Martial God Palace, possessing a genuine Desolate Rank cultivation level and unfathomable strength.

He had only glanced at Chen Feng's body briefly, yet he had accurately locked onto the Vajra Core within him. This level of insight surpassed that of any other powerful figure he had ever encountered.

Although he has a terrible reputation, everyone says he is the only mentor in the Martial God Palace who "accepts anyone who pays money," as if anyone can become his disciple as long as they pay enough.

However, it was precisely this "profit-driven" mentor who managed to produce top students who ranked among the top three in the entire Martial God Palace.

One generation after another, the powerful individuals who emerged from his tutelage are now found throughout the military and political centers and martial arts sects of the Great Xia Kingdom. Many of them have even surpassed the cultivation levels of their former mentors who once looked down on Yu Qian.

This is the most incredible, and also the most overlooked, aspect.

How could a mentor who only cares about money and doesn't care about qualifications possibly produce so many exceptionally talented individuals?

Thinking of this, the last bit of hesitation in Chen Feng's heart vanished. Only unwavering determination remained.

"It seems that accepting money whenever possible has never been the true nature of our surplus funds; it's just a facade."

He looked up at the remaining money, which was fixed not far away and watching him.

Yu Qian didn't leave; he just smiled shrewdly like a merchant, while eyeing Chen Feng in the distance.

It was as if he had already figured out all of Chen Feng's thoughts, and was just waiting for Chen Feng to make the final decision.
