In a trance, Xu Han suddenly realized that he was in a sea of bones, and his corpses were full of bones.

"No wonder the atmosphere here is so terrifying, full of the smell of death. Xu Han calmly glanced at these corpses, and his heart suddenly changed.

Immediately, Xu Han raised his eyes and looked directly at the pair of demonic eyes in the blood sky, "Are you killing all these people?"

"I did it. ”

Xu Leng laughed: "Also, since you are a demon, it is not strange to kill people." I'm just curious why so many people have died in this secret place when it's so hidden. ”

"There are two reasons, one is that this mountain is Yuanling Mountain, a place of spiritual veins. Second, humans are domineering and greedy. ”

Xu Han thought for a moment and somewhat understood. The Sword Demon's answer was vague, but the meaning was not difficult to understand. Yuanling Mountain is the land of spiritual veins, and it is also an excellent place for cultivation, and naturally there will be countless masters who want to fight for this place. Human beings are very domineering and greedy, and powerful people are simply not willing to share this cultivation treasure land with people who are weaker than him, so there are many people who have the same experience as Xu Han, and their fate is to become one of the white bones under Xu Han's feet.

"As a demon, I am amazed by your confession. The corners of Xu Han's mouth lifted slightly.

At this moment, another cold and treacherous voice sounded.

"Of course! we're much more confessed than humans, hey, hey, hey!"

A flash of surprise flashed in Xu Han's eyes, because this voice came from his body.

"Who are you?" Xu Han's eyes sank.

"Yo, boy, have you forgotten me?" said a hint of banter in the cold and treacherous voice, "I've been in your heart for so long." ”

A cold glint suddenly flashed in Xu Han's eyes, "Are you, heart demon?

"Hey, hey, hey, I'm a demon, how can I die so easily?"

The voice of the sword demon came again: "Heart demon, why are you hiding in this son's heart. ”

"Because, he's very strong, hehe!" the heart demon seemed to be snickering, "Although his strength is still very limited now, I am very optimistic about him, and I will wait until the day when he is strong enough to take him for myself!"

"Don't you think about it. Xu Han couldn't help but let out a cold snort, his brows furrowed.

"Hehe, no one can resist the demons...... "The demon's voice suddenly became small until it disappeared completely.

The atmosphere suddenly became silent and silent.

The eyes in the blood sky seemed to be thinking about something, and for a long time, the voice of the sword demon sounded in Xu Han's ears.

"Boy, do you dare to make a pact with me?"

Xu Han raised his eyebrows: "Contract, what, you don't plan to kill me?"

"If you dare to promise, I will not kill you. ”

"Tell me about it. ”

"I have an old enemy, the demon of men, and I was defeated by his hand before I fell into the soul body. If thou wilt avenge me, I will give thee strength. ”

Xu Han's eyes flickered slightly, "You mean, as long as I can kill people and demons for you, not only will you not kill me, but you will also give me strength?"

"Exactly. ”

"But, is your strength worth it?" Demons are also divided into levels, and sword demons and human demons obviously belong to a very advanced category. Asking Xu Han to kill a high-level demon is a rather dangerous thing with his current strength. Of course, killing the demon does not violate Xu Han's conscience, the conditions are reasonable, and he is not unacceptable. It's just that Xu Han needs to know whether the conditions provided by the Sword Demon are worth it for him to do this thing.

As for not killing him, to be honest, the exit of the secret realm was not far away, and Xu Han believed that he could completely escape from the hands of the sword demon, which could not be a factor to consider.

"You won't regret it. ”

When the words fell, the eyes in the blood sky suddenly closed, and suddenly, a blood light fell from the sky and hit Xu Han's body.

Xu Han only felt that powerful and terrifying forces had penetrated from his limbs and bones, pouring into the sea of qi, and merging with the true qi in the sea of qi. That feeling is extremely enjoyable and extremely refreshing.

The blood light gradually disappeared, Xu Han was like a spring breeze, and his body was indescribably comfortable and relaxed. He slowly opened his eyes, the sky was no longer blood-colored, but clear blue, and his body had also undergone earth-shaking changes, indescribable, unclear, if I had to describe it, I could only use two words: powerful.

Feeling the incomparably powerful power of the Sword Demon, Xu Han couldn't help but smile and secretly shook his head in his heart. This sword demon, I don't know whether to say that it is upright or make its own opinion, Xu Han has not agreed, it has made a decision on its own.

However, this power is indeed valuable enough to be worthy of the condition offered by the Sword Demon.

The corners of Xu Han's mouth raised slightly, and with a bang, the Heavenly Thunder Sword was held in his hand, and he saw a flash of essence suddenly flashing in his eyes.

"Magic sword, darkness. ”

The blade of the Heavenly Thunder Sword was gradually blackened by a strange force, emitting a dark halo. At the same time, behind Xu Han, a phantom appeared, the phantom was completely pitch black, the body shape was different from that of a human, like a demon, and a pair of blood-red eyes were suffocating.

"This is the power of the sword demon. Xu Han said secretly in his heart. Only the Demon Sword Intent of the Sword Demon could be so perfectly fused with the True Qi and the Sword Soul. The only thing he can fuse with the Demon Sword Intent is the Dark True Qi, and when his Law of Light, the Law of Lightning, and the Law of Flame step into the Rule Realm one after another, he can also make the Demon Sword Intent fuse with them.

"With the power of the sword demon, I should be able to barely fight Tanglin now. Xu Han muttered. However, it was only reluctantly, which was obviously not Xu Han's purpose. He looked around and decided to cultivate in this secret realm for a few days first.

After three days of cultivation in Yuanling Mountain, Xu Han's Law of Light had already cultivated to the eighth realm, and he would soon be able to step into the realm of rules. As long as he can use the Light True Qi perfectly, he can fuse the Light True Qi and the Dark True Qi into the Chaos True Qi just like he did on the tenth layer of the Demon Punishment Tower, and when the time comes, Tanglin will not be worth mentioning in front of him at all.

Xu Han looked so powerless in the face of Tanglin, it was completely because his other hole cards had not yet entered the threshold of the realm of truthlessness, and all he could use now was the dark rules and dark true qi, and there was no problem in dealing with masters in the same realm, but when dealing with masters higher than his realm, he became very powerless.

When Xu Han had four true qi at the same time, namely Dark True Qi, Light True Qi, Demon Flame True Qi and Thunder True Qi, not to mention Tanglin, a True Realm Double Intermediate Master, even if it was a True Realm Double Peak Master, he didn't care about it at all.

The density of the True Yuan of Heaven and Earth in the secret realm was obviously not as good as that of Yuanling Mountain, but Xu Han had the Bright Ding, so he did not have much impact on the comprehension of the mysteries of the law. In the same three days, Xu Han's Law of Light broke through the last obstacle and sublimated to the realm of rules.

From that moment on, Xu Han's absorption of the Bright True Qi in the Bright Ding had greatly increased, and he was extremely greedy.

At the same time, the light true qi and the dark true qi fused within Xu Han's qi sea, and streams of chaotic true qi were born in the interweaving of light and darkness, pouring into the qi sea.

A gray aura appeared on the surface of Xu Han's body, as if he wanted to kill heaven and earth.

The rule of light is purification. The rule of darkness is to devour. And the rule of chaos is to exterminate and kill!

"Hey, hey, hey, hey, see?!I'm not wrong!This kid has a lot of potential!Keep getting stronger!The stronger the better! Your body, sooner or later, it's mine!"

"Shut up, don't disturb him. ”

Time passed little by little, and finally, Xu Han opened his eyes, and a trace of chaotic qi flashed in his deep pupils, and then, he exhaled a long breath of turbidity, and his eyes flashed with essence.

Then, Xu Han got up, pulled out the Heavenly Thunder Sword, and after taking a deep breath, his expression suddenly turned cold, "Demon Sword, Chaos." ”

The Heavenly Thunder Sword trembled slightly, and the blade was gradually impregnated with chaotic qi, and its color was gray. Behind Xu Han, a chaotic phantom appeared, resembling a demon, with a pair of blood-red eyes, hanging on the demon's hideous face, extremely evil.

"I also need to comprehend the Chaos Sword Technique in order to maximize the power of the Chaos True Qi. Xu Han muttered to himself, the corners of his mouth raised slightly. He didn't need any sword skills now, and he could completely crush Tanglin.

Yuanling Mountain, inside the cave. Tanglin was cultivating here, but a huge roar startled him, and when he looked up, the top of the cave had been completely torn off and turned into an open field.

"What person?!" Tanglin was furious and jumped up. If it weren't for the fact that he didn't cultivate deeply, the shock just now would have been enough to make him go mad. Immediately, his pupils shrank suddenly, and a layer of gloom appeared on his face: "It's you?!

Xu Leng smiled: "You should regret not killing me with a sword." ”

Tanglin sneered: "Regret? Hmph, it's not too late to kill you with a sword now!"

After that, the thunder and lightning true qi diffused out, and a sense of paralysis crept up on Xu Han's body.

The corners of Xu Han's mouth were lightly raised, and a cold smile appeared in his eyes, "You want to kill me now?" ”

"I see you broke your brain three days ago, and you see if you can still move now?"

Xu Leng smiled silently, and his body did not move at all.

"You can only be slaughtered by me now, and I can kill you as much as I want. Tanglin's smile was cold. The paralysis rule is a kind of rule that is full of control, and it is the same as the ice rule. Especially when dealing with a strong person whose realm is lower than himself, the rule of control is the best rule, just imagine, the other party can't even move, what else can he resist?

"Then you try. Xu Han's pupils were extremely calm.

"Look for death. Tanglin shook his head, his gaze suddenly sharpened, "Go die!" When he landed, the sword soul appeared in his hand and quickly stabbed at Xu Han.

Burst!

Tanglin's pupils contracted suddenly, his body swept past Xu Han, and he stepped forward a few steps abruptly, and then his body stiffened, and he froze there.
