An oath is a certain agreed ritual set by one's own beliefs, and the rules that one swears to abide by, so as to pay a specific price, make a vow with strength, and thus obtain a powerful ability to surpass oneself.

The oath is made in the heart, and the more difficult the decision, the greater the power obtained, if the energy hidden in the body is usually compared to addition, then obeying the rules of the heart is multiplication, the power will increase exponentially, its essence is to be activated by strong emotions or firm beliefs, and its own potential is fully exerted, to obtain absolute power.

The oath can be freely proposed by the user, and the inherent characteristics can be freely chosen, and the rules can be made, but although strict restrictions can make one's own power explosive, once the oath is broken, the reaction force will fulfill the agreement you made, and that is at the cost of the soul.

"Oath?!" Noah broke out in a cold sweat.

But power can't be obtained out of thin air, even if you have the intention to exchange the price, but you have to have the object of the transaction in exchange for power, who will provide the power.

Hades replied, "This is the price of the oath of the heart, and if you acquiesce to the oath you have made and keep it, you will gain the power corresponding to it!"

"I see!" Noah nodded, "Then how do you swear?"

"It's very simple, you swear that from now on, you will never maliciously kill someone by force!"

Noah immediately frowned: "Never kill with malice?"

"That's right, never take the initiative to kill people with malice!" Hades sneered, deliberately pronouncing these words very seriously, and before Noah could understand the true meaning of the words, Hades continued.

"Well, to the extreme, no matter how hated the enemy is standing in front of you, you must not kill his life, otherwise the spirit will collapse, and no one will know what will happen to the consequences!"

Noah thought for a moment and immediately understood the main point: "But why did I make such an oath? To restrain myself with this oath, so that I have to focus on defense, and then improve my defensive ability? Although I still can't understand the principle of the specific operation, isn't it useless to use the power that cannot be used to attack?"

"Who said there was no more?" Hades interrupted lightly, "The oath made also pays attention to certain skills, the content of the oath is not to take the initiative to hurt others, the focus is to take the initiative, malice and kill, this is an oath to the heart, as long as it is in line with the heart, then the oath is obeyed!"

Noah was stunned for a moment, and then woke up: "Even if you can't carry out the means of active attack because of the constraints of the oath, if you provoke the other party with words, it will be a passive defense, as long as you are firm in your heart, stick to the definition in your heart, and as long as you think that you will kill the lives of others without violating the rules, you can be regarded as abiding by the oath!"

Hades nodded, "Well, the oath is indeed an oath to the heart, as long as you are firm in your heart that what you are doing is right, you will not break the oath!"

Noah laughed, "Lord Hades, you don't need to test me with these words...... If nothing else, even if I make a vow to swear by my life now, I may not be able to defeat the demon king Satan!"

"Well, it's good that you have this self-knowledge, you have to give it up before you get it, with your intelligence, you should be able to clearly realize that once the oath is established, you will also sacrifice something, you have a choice, there is no need to let yourself be so passive!"

Noah nodded, "So will the vow date always be valid, and will the price it pays continue to last?"

"How long do you think this oath will be valid?!" Hades sneered, "The content of the oath will change according to the wish of the heart, if your wish is to defeat the demon king Satan, then this oath will also expire instantly after you defeat the demon king Satan, and the power of the oath will be lost, then you will no longer have to obey these rules, but if your wish is an eternal prayer, it will last!"

"I see!" Noah nodded, then looked up, "So how do I make a vow now?"

Hades laughed, then slowly stood up, a little light from his fingertips shining into Noah's brow.

In an instant, Noah's mind suddenly shone brightly, and her soul quickly condensed, condensed into an ethereal, as if it was about to break away, and then became condensed, and an illusion shaped like herself condensed out.

"It's ......" Lecobel was startled, then closed the corners of her mouth.

The phantom in front of him moved slightly, stretched out his hand and plunged into Noah's chest, and then radiated divine power.

There was a coolness in his heart, as if he had easily activated a powerful force, which made Noah tremble all over her body, and successfully condensed the oath, although in the name of her heart, but when she swore it, she was not shocked, only a circle of colorless and formless ripples spread out from her body, swept through the depths of her soul, and then disappeared into all things, in fact, she didn't feel anything, a nothingness, as if she had deprived herself of nothingness...... However, Noah knows very well that after the oath is established, he must strengthen his beliefs, and if he really dares to break the oath, it is impossible to say what effect the violation of the oath will have when it is fed back to his body.

The oath was fulfilled, Noah slowly opened her eyes, and waited for a crystal power to bloom from her body, the feeling that everything was under control had dissipated, but the effect of the oath was retained, engraved in the soul, body, and spiritual power...... Everywhere, as Noah moved her body, the bones here and there made a crunching sound, but there was really no change in sight.

"Is that done?" Noah held out her hand and looked at her barely changed body in surprise.

"After that, you have a few days to digest the benefits of the oath to you, and at the same time to change your tactics, generally speaking, as long as you are among the strongest, their minds are enough to firmly restrain their behavior, and these constraints, but they should not be a problem for you, right?"

Noah nodded: "Don't worry, of course!"

Hades nodded, "Okay, then let's start the next part, actual combat!"

Hades winked at Lecobel, who was on the side, and then stepped forward.

"I'll be your opponent!"

............

The rain was still falling, it seemed deserted, in front of the city of Dhara, there was a lost forest, as quiet as the deep forest where everything was sleeping in the fear of death, the figures of ghosts and the creepy cries could make people hallucinate the underworld, the stout and towering strange plants, the nameless insects with enchanting colors, the unknown liquid left on the surface, they were all dead.

Endlessly surrounded by blood, just along the way, a large number of strange corpses of the demon clan were scattered in piles, that was the revelation of the terrible demon severed, the thick smell of blood was extremely bloody, and some bloodthirsty demon insects crawled among the corpses, and the corpses twisted each other, it seemed that they had been dead for a while.

Hokko and the Yuraiya stopped at the foot of a mountain, and the Protector Beast that was supposed to be guarding it was gone.

Gritted his teeth, "It seems that things have already happened, is it too late!"

There was a strange smell in the air, and then there was no smell at all, even the smell of Yuraiya was gone, and he was clearly beside him.

"Let's go, something is wrong!" Huo Ko was surprised, but he was very calm.

Yuraia nodded hurriedly.

The dragon's intuition has always been very accurate, and there is a faint murderous aura in the air, which is different from sharpness, this murderous aura contains cruelty and blood.

They hurriedly crossed the mountain and came to the Dhara King City, the whole huge city became fragmented, countless huge hollows dressed in the Dhara King City, directly wearing the King City into a hornet's nest, from time to time countless stones and debris fell from the broken place, like a huge building made of building blocks, the slightest push will collapse the whole thing.

I didn't feel the breath of life, only endless grievances and anger gathered in the entire sky, the water flowed down the trunk of the tree, and then gathered on the surface, mixed with countless demon corpses, slowly emitting the stench of rotting wood, looking forward along the city gate were countless corpses, full of stench, and the skin had long been rotten. The thick smell of flies and maggots began to slowly spread, and many white fly maggots rubbed on the corpses, as if tens of thousands of them were intertwined, and the dead corpses had bloodshot eyes and wide open mouths, and they were all killed by a single blow.

This is the power to give all things "death", rich dark magic, eroded everything and ceased to exist, I really didn't expect Satan to move so fast, ruthlessly killing the entire people in the Dhara King City, there is no longer other magic around it, it seems that Satan came to the Dhara realm single-handedly, and the power of the demon king Satan outside the realm is strong but far less outrageous than in the realm.

In this way, King Dhara is already dead, and his breath is not felt everywhere, no matter how fast Satan moves, it should take time to defeat King Dhara.

"Wait, there's still someone alive!" Yuraia suddenly shouted in one direction, and Hoko hurriedly ran after him, and there was indeed a faint gasp in that direction.

A demon with a face like a white corpse, his body has been eroded by Satan's dark magic, blood is constantly spilling from his body, his lips tremble, and he has a faint voice, which is the limit for him.

"Yes...... Satan, the Demon King!"

"Did Satan, the Demon King, really attack here?" Huo Ko shouted, "Where is King Dhara, and has King Dhhara also killed by him?"

"King Dhara...... By... "The other party gritted his teeth and said, "His next target...... It's the Rakshasa realm!"

At this moment, a blood-red spear suddenly shot into the chest of this demon from a distance, his body instantly shattered, and then countless black bands of light suddenly appeared under his feet to instantly restrain their bodies, and a huge black shadow cracked out a terrifying giant mouth with fangs, as if to devour them.

"I remember this is!!"

Yuraia's eyes froze, and the golden holy sword turned into a thunderbolt, hurriedly cutting off the black and yellow belts that bound their bodies, and then broke away, and not far away, the blood demon and the shadow demon appeared in their eyes.

"I didn't expect there to be any fish that slipped through the net!" said the Shadow Fiend, disdainfully, "And two more from other places!"

"Blood Demon, Shadow Demon!" Huo Kou gritted his teeth and shouted, "Where is the Demon King Satan!"

Shadow Demon sneered, "Just because you're not qualified to mention Lord Satan!"

The Blood Demon replied, "Lord Satan is not here, he has already left, send me and the Shadow Demon to kill all the demons who are still alive in the city of Dhara King!"

Huo Kou asked, "Then the next target I just said is also true of the Rakshasa Realm!"

The Blood Demon nodded, expressionless, "It's true!"

"Damn!" Huo Ko gritted his teeth, "Then now we must tell this information to the demon kings of other realms!"

"Hmph!" At this moment, the pitch-black shadow turned into countless spikes and shot towards them, and the two hurriedly dodged.

Shadow Fiend laughed "Do you think you can go back alive, hahahaha......"

The Blood Fiend frowned, and at the same time, he condensed a blade of blood to hold in front of his chest.

Huo Ko's face changed slightly, "Blood Demon, do you still want to fight me?"

The Blood Demon's face was bitter, and he gritted his teeth and replied, "I am a tool of Lord Satan, and it is my destiny to fight for my lord!!"

At this moment, a beam of golden flash suddenly shot away, and Yuraia slashed at the Shadow Demon with the holy sword in hand.

"Why all that, as long as I know that they are some of Satan's subordinates who captured Noah, then it is enough to defeat them!"

"That's right!" Huo Ko was slightly stunned, and then gathered a powerful force of collapse in his hand, and a dazzling red light blade was clenched in his hand.

Stared coldly at the Blood Fiend, "As long as I know that you are my enemy, then I have only one goal, which is to kill you!"

Bloodseeker nodded.
