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

Upon returning to the guard headquarters, Chen Feng immediately took the certificate for the use of the fighting arena to Qu Lu.

Upon seeing the Jian family certificate in Chen Feng's hand, Qu Lu's eyes lit up, and she looked at Chen Feng with a hint of curious goodwill.

Qu Lu: "A three-month lease on the Jian family's fighting arena is a hard currency worth over two hundred thousand yuan in cash, Chen Feng..."

Chen Feng: "Jian Mei already reminded me that this thing is quite valuable."

Qu Lu looked at Chen Feng with great interest, her eyes showing a hint of appreciation.

The more you look at Chen Feng, the more you feel that he is a team member who will bring good luck.

Qu Lu: "It was actually personally authorized by the future young master of the Jian family, interesting... really interesting..."

Chen Feng: "Team Leader Naqu, I'm handing this over to you. After you pay the fines for our team, just give me the rest."

Qu Lu: "No problem, I'll give you every last penny of the rest."

Just then, Liu Siyu happened to pass by the two of them and noticed that they both seemed to be beaming with smiles, as if they had found a treasure.

"What are you laughing at?" Liu Siyu asked curiously as she approached the two of them.

Qu Lu immediately handed the usage rights certificate in his hand to Liu Siyu.

"Uh... this is... a three-month lease for the boxing arena?"

Even someone as thick-skinned as Liu Siyu immediately widened his eyes.

Because she knew very well how huge the daily traffic and how considerable the profits were at that underground fighting arena.

If you have this certificate, even if you don't do anything, you can sell it on the street and get at least 100,000 yuan in cash.

In Haixing City, 100,000 yuan is enough for a down payment on an ordinary house, and in the guard's camp, it can even buy a Xuan-level cultivation technique or some Di-level cultivation techniques.

Thinking of this, Liu Siyu immediately looked at Chen Feng and asked in a serious tone, "Chen Feng, you wouldn't happen to be with Jian Mei...?"

Seeing the slight nervousness on Liu Siyu's face, Qu Lu secretly smiled.

Only Chen Feng said somewhat irritably, "That's not true. I just found out they were doing something bad, so I got lucky."

Upon hearing this, Liu Siyu seemed relieved and immediately nodded.

"That's good... Everyone, let's chat inside the vehicle. I'm going to leave work early today, I'm a bit tired lately..."

...

After a day of searching for criminals, Chen Feng took a shower in his room and then went to the Tower of Babel training room again.

Since the attack on the Starfish City Guard headquarters and the death of Wei Yang at the hands of the demons, Chen Feng has rarely continued to study the "Soldier Body Tempering Technique".

It wasn't until tonight, after Qu Lu secured a day off for everyone, that Chen Feng finally had time to continue his studies.

[Soldier's Body Tempering Technique, First Level: Armor Tempering]

[Body Tempering Introduction: This process strengthens and modifies the cultivator's physical body by simulating high-pressure loading, iron sand impact, and extreme environment adaptation. It also uses faint spiritual energy to locate and activate the cultivator's spiritual energy nodes.]

[Armor Tempering Levels: 1-10, currently at level 4, estimated training time to reach level 7]

【兵甲淬体效果：基础力量+300%、骨密度×7、基础敏捷+200%、灵能兼容度+500%、其他属性+150%±20%】

【修炼者的基础属性：力量117↑敏捷74↑感知58↑智慧56↑灵能169↑】

Looking at his own potential data, Chen Feng frowned.

According to his own calculations, as long as he can fully operate the first level of the Warrior Body Tempering Technique, "Armor Tempering," his probability of becoming a Primordial-level powerhouse will be significantly increased.

Moreover, mastering the "Armor Tempering Technique" means that one has enough confidence to establish oneself as a Gold-ranked Demon Slayer.

At this time, demons frequently appeared in Starfish City, and many criminals began to carry out their old schemes.

However, Wei Yang and Bai Fei, whom Chen Feng once relied on, have both fallen into difficulties and need time to rise again.

"It seems I can only rely on myself now," Chen Feng said calmly.

As Chen Feng took a deep breath, he immediately reached out and pressed the switch to start his cultivation.

The array patterns on the ground suddenly lit up crimson, and the cultivation machine above began to roar, countless red lights instantly engulfing Chen Feng...

In an instant, Chen Feng felt a pressure as if a mountain range was pressing down on him, or as if he had swallowed a lot of strong liquor. As his Adam's apple bobbed, his body turned red like forged iron and began to emit extremely hot steam!

Chen Feng was breathing heavily, seemingly unable to bear the pain any longer.

Although Chen Feng had experience in using "Armor Tempering Technique", the higher the level of "Armor Tempering Technique", the harsher the training environment became!

The "Tia" psionic energy clung to Chen Feng's body like living lava, leaving deep red marks on his skin before slowly disappearing.

Driven by low-frequency psionic energy, the muscle fibers felt as if they were being pierced by dozens of steel cones, and each muscle contraction brought extremely intense pain.

At this moment, Chen Feng, who felt as if he were in purgatory, once again experienced that excruciating pain...

Although he didn't know how the former "Fire Salamander Legion" trained, Chen Feng knew very well that even his willpower was hard to withstand, let alone others.

However, if Chen Feng gives up this training, he may not be able to cultivate to the second level of "Soldier's Body Forging Technique".

"No! I can't give up!" Chen Feng suddenly said through gritted teeth.

Just as Chen Feng was still struggling to hold on.

The Lucky Contract has sent another life-saving message!!

Such a good thing?

Chen Feng did not wait and immediately agreed to the order from the Lucky System.

However, to his surprise, he was about to encounter the activity he had been most looking forward to...

Ding!Ding!Ding!

Ding!Ding!Ding!

(๑•̀ㅂ•́)و✧ An untimely firework exploded in front of Chen Feng...

WTF!
