Strongest Mage with the Lust system

[Alright then. I'll help you in exchange for that demonic essence you got me from that king mage.] The system cackled.

On hearing this, Max didn't say anything and just nodded. Although he knew that demonic essence should net him many shop points in exchange, his life was worth much more.

Furthermore, it wasn't as if his miserly system was going to reimburse for the demonic essence. Why? Because ever since they extracted it, he had been asking for shop points, but the system always gave excuses like I'm busy or I'm calculating your shop points or sometimes it would just play dead. So, he had lost any hope of getting anything in return for that essence.

Now that the system was offering to help me in exchange for that, he didn't have any problem accepting the deal, even though he faintly felt he was losing out quite a lot here.

"You puny human. You killed my two companions. I'll take you back from where you came from and slaughter all of your family and friends before killing you." The demoness said, her red eyes glinting with ruthlessness.

"Let's first check where are you from?" As she said this, she grabbed toward Max's head. She wanted to use her demonic arts to check his memories. But before she could touch him, a strong sense of death filled her heart.

Whoosh!

Without hesitation, she flapped her bat wings and shot backwards.

[Keke, little lady. Where are you going in such a hurry?] An eerie laugh rang out in her ears as soon as she moved.

Hearing the voice, she knew she was in immense danger. Her demonic energy burst out and she turned into a streak of black light, escaping into the distance.

"Fuck. Why is a demon helping that human?" While running, she couldn't help but curse.

Boom!

Just then, a demonic energy, many times more powerful than hers, burst out from behind her. Feeling this, the unease in her heart grew.

'I've to use blood escape.' She thought. The blood escape was a demonic technique which would increase the user's speed by several fold when they burned their demon blood.

Just as she started igniting her blood, a voice sounded in her ears and all the blood and demon energy in her body froze.

[Little girl, you won't be able to escape even after using blood escape. Then why burn your precious blood essence, which can help my little guy here? Come here.]

As soon as the voice finished speaking, she felt an invisible energy envelop her. It immobilized her completely and flung into air before taking to the place where Max was lying, unconscious.

"Se-senior… please forgive me. I didn't know this human was your toy. I'm willing to compensate you." She gathered her courage and apologised.

[Hehe, such a nice doll! Since you are from the blood wing tribe, I won't kill you.] The system laughed.

The demoness became ecstatic when she heard this and hastily said, "Thank you, senior for sparing my life. I'm sure my tribe will be grateful."

[Hehe, grateful? If they knew my identity, I'm sure they would want nothing more than to burn me alive.] The system cackled evilly.

Upon hearing this, the demoness shivered. Could it be this monster was her tribe's enemy? If so, why would he spare her life?

[Don't be afraid, little girl. Since I said I won't kill you, it means I won't kill you.] The system said, assuaging her worries before it added, [However, I'm not sure about this kid here. You thrashed him so badly that he would want to kill you at any cost.]

"This weakling? If senior doesn't interfere, I can kill cough. I mean, I can handle him easily." The demoness said with disdain.

[Hehe, you are right. You can easily kill him. But the problem is, if he asks me to immobilize you, I'll have to do it and once you are immobilized, can't he can easily kill you then?] The system asked, laughing.

The demoness paled when she heard this. Just as she was about to speak, the system said, [It's useless pleading me. I'm not in charge, he is. However, I can persuade him to spare your life if you agree to become his sex slave.]

"NEVER." The demoness shouted in anger. She was the proud daughter of a six star elder of the blood wing tribe. How can she be a human's sex slave? It would be a disgrace to her, her tribe and the whole demon race.

[It's alright. You can wait for your death then.] The system nonchalantly said.

After that, none of them spoke and waited for Max to wake up. Because the system had already fed him a healing pill, his injuries slowly recovered and his eyelashes trembled, indicating that he was about to wake up.

Thump! Thump! Thump!

The demoness' heartbeat quickened. She knew death was near.

As if the system knew her state of mind, it said, [You can still save your life if you put your useless pride aside.]

"I…" The demoness clenched her jaws before reluctantly saying, "I agree."

[Hahaha. Good decision girl.] The system laughed.

The demoness didn't respond and stood there woodenly.

A while later, Max opened his eyes.

Rustle!

When he tried to move his body, he felt severe pain in his chest, hands, and inner organs.

"Argh! That bitch did me good." He hatefully said and then asked, "Did you kill her?"

[Nope. I just immobilized her. You can decide what you want to do with her.] The system answered.

Max glanced around and saw the demoness standing a few meters away from him, looking at him with deadpan eyes.

Seeing her, his anger flared, and he just wanted to charge and break her head with one punch, but he stopped himself.

First, he took out some healing pills and threw them into his mouth. After a while, his broken bones and injured organs started healing.

After half an hour, 70% of his injuries were healed completely.

He slowly stood up, walked to her with slow step before stopping in front of her. This demoness was half a head taller than so he had to raise his head slightly to look into her eyes.

Calmly, he stretched out his hand and then suddenly,

Slap!

He slapped her beautiful face with all of his physical strength. The crisp sound of his slapped reverberating through the forest.

Buzz!

The demoness felt her head buzz and was disoriented. When she came to her senses and realised what had happened, her blood-red eyes blazed with immense fury. She wanted to tear him limb by limb, but unfortunately, she couldn't even move and only glare at him hatefully with her half-swollen face.

Seeing her become angry, Max smiled sadistically. "Hehe, feeling angry now? Didn't you enjoy pummelling me just a while ago, huh?"

Slap!

Saying this, he slapped the other side of her face, causing it to swell as well.

Puah!

The demoness become so angry that she spat out a mouthful of blood. "Human, if not for the senior backing you, I would've killed you." She shouted, unable to hold back.

Slap!

"Who allowed you to speak?" Max asked, slapping her face once again.
