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

After two days, Chen Feng finally mastered the "Soldier Body Forging Technique" to the 8th level, and his basic attributes all over his body underwent a qualitative leap.

Just before sunrise, Chen Feng took two bottles of beer and sat on the edge of the balcony on the top floor of the main building.

I was drinking beer while gazing at the scenery in the distance.

The city skyline is being tinged with a pale blue glazed glass. The morning mist that wanders between the buildings is being dispelled, and the wingtips of the occasional flock of pigeons are tinged with gold, drawing silver lines on the gradually brightening sky.

The distant buildings gradually faded from the shadows, and the ground scenery began to emerge from the chaos:

The dark glass curtain walls of the skyscrapers reflected an orange-red light. People's Square was also filled with moving figures—morning exercisers whose silhouettes blurred against the backlight. The lingering scent of night-blooming jasmine wafted in the breeze, and pajamas on the clotheslines trembled gently in the wind.

All of this seemed to be quietly waiting for the golden sun to peek out from the horizon, thus bathing the entire city in a honey-colored halo.

Chen Feng placed his hands on the balcony behind him and lazily opened the Lucky Contract System.

Watching the 45-second progress bar.

That was the progress bar for "Double return of luck and items for 60 seconds".

If Chen Feng hadn't discovered that the event had a pause button at that time, he would have been extremely lucky to save the remaining 45 seconds of the event time.

If the training time of "Soldier Body Tempering Technique" directly affects the return time of "double luck and items", then Chen Feng will definitely regret it.

Chen Feng examined the four contract exchange coupons, his curiosity stirring within him.

According to the rules of the "Lucky Contract" system.

"The Lucky Contract is an advanced contract within the Lucky Contract system, and as a T0-level contract system, the Lucky Contract system allows the simultaneous use of contracts from other 'True Name' contract systems."

With that in mind, Chen Feng took out one of the "Random Contract Exchange Coupons" and clicked the exchange button.

Ding!Ding!Ding!

Ding!Ding!Ding!

[Lucky Contract: Congratulations, host! You have successfully redeemed a random contract exchange voucher and obtained a "High-Level Neutral Contract".]

【Advanced Neutral Contract: The Advanced Neutral Contract is an advanced contract designed for the Demon Slayer clan. Its purpose is to store the energy they possess, serving as a strategic resource reserve for the Demon Slayer clan (Price: 7500 Luck Points)】

Upon seeing a high-level neutral contract worth 7500 luck points, Chen Feng immediately spat out the beer he was drinking.

7500 luck points, what does that even mean?!

This means that Chen Feng can hunt down a single Earth-rank aquatic giant beast with Bai Fei; or, after reviving Wei Yang, he can assist Bai Fei in hunting down three Xuan-rank peak giant beasts.

Whichever option he chooses, Chen Feng will be able to steadily advance to the rank of Gold Demon Slayer.

"That means my Golden Demon Slayer title is now secure," Chen Feng murmured.

Chen Feng immediately used the "Advanced Neutral Contract" and watched as the luck value in the upper right corner soared up, finally settling at 7500.

Chen Feng breathed a deep sigh of relief.

He hesitated as he looked at the remaining three random contract exchange coupons.

According to the mean reversion theory, the random contract exchange tickets will most likely be exchanged for random contracts of low value, and it is almost impossible to get a valuable contract like the "Advanced Neutral Contract" again.

But you still have to step into the pits, otherwise you'll never know when wealth will come.

So Chen Feng directly exchanged for another random contract voucher.

Ding!Ding!Ding!

Ding!Ding!Ding!

[Lucky Contract: Congratulations, host! You have successfully redeemed a random contract voucher and obtained a "Black Rose Contract".]

【Black Rose Pact: The Black Rose Pact is used by the Exorcist clan to establish an alliance with a mage. When an Exorcist and a mage establish a pact, both will receive a black rose ring. When the other is in danger, the mage or exorcist can choose to appear immediately beside the other and grant both a temporary and significant combat power boost (Price: 1500 Luck Points)】

Looking at the price, Chen Feng's mood didn't fluctuate much at this moment.

He then redeemed a random contract voucher.

...

Ding!Ding!Ding!

Ding!Ding!Ding!

[Lucky Contract: Congratulations, host! You have successfully redeemed a random contract voucher and obtained a "Treasure Hunt Contract".]

[Treasure Hunt Contract: The Treasure Hunt Contract is a pact between the Demon Slayer clan and a treasure hunter. It can be activated directly. When a Demon Slayer establishes a contractual relationship with a treasure hunter, the Demon Slayer will gain the ability to explore secret treasure realms. By completing the trials of the secret treasure within the realm, the host will directly obtain the hidden immense wealth. However, within the secret realm, the combatant's abilities will be greatly weakened, potentially leading to life-threatening situations. (Price: 850 Luck Points)]

Chen Feng remembered that the Lucky Contract System once said that if you find a treasure that surpasses your own level, you can also get a significant boost to your luck.

Although the treasure hunt contract may bring danger, its acquisition mechanism offers double rewards: both the treasure and luck.

...

Ding!Ding!Ding!

Ding!Ding!Ding!

[Lucky Contract: Congratulations, host! You have successfully redeemed a random contract exchange voucher and obtained a "Medium-level Combat Power Contract".]

[Intermediate Combat Power Contract: The Intermediate Combat Power Contract is a combat scroll specially developed by the Demon Slayer clan for combat. It can directly affect enemy units. When used in battle, the Demon Slayer can directly reduce the opponent's true combat power by 45% and base attributes by 30% for 20 seconds (Price: 1000 Luck Points)]

Looking at the Black Rose Contract, Treasure Hunt Contract, and Intermediate Combat Power Contract on his system interface.

Chen Feng began to consider whether he should also sell these three contracts.

The "Black Rose Contract" is the most valuable because it provides the greatest boost to combat power. It not only allows for direct location teleportation but also grants a huge combat power bonus.

However, although the function of the contract is powerful, Chen Feng has not yet come into contact with any powerful magicians. For Chen Feng, it is almost like something that has been left to gather dust in a warehouse.

Thinking of this, Chen Feng directly sold the "Black Rose Contract" and saw his luck value suddenly reach "9000".

"The intermediate-level combat power contract is likely the trump card against the Greedy Demon, so we can't sell it," Chen Feng murmured. "As for finding the secret treasure, we can certainly give it a try."

Thinking of this, Chen Feng immediately placed the "Treasure Hunt Contract" in his hand into the usage box.

Ding!Ding!Ding!

Ding!Ding!Ding!

(๑•̀ㅂ•́)و✧ A firework suddenly exploded in the center of Chen Feng's vision...

[Lucky Contract: Congratulations, host! You have activated the second True Name System, "Treasure Hunt." Next, you will witness the truth hidden within this world.]

Chen Feng's vision swept across a deep blue-black wave. These dark ripples gathered from the edge of Chen Feng's vision towards the center like waves, and then spread out again, as if they were invisible giant waves sweeping across the world.

Finally, all the shimmering waves in the field of vision dissipated.

Chen Feng's eyes readjusted to the original world, yet he could vaguely sense the secret treasure hidden in the dark corners of the world.
