At the same time, Han Dong's body erupted with an extremely terrifying and murderous aura, as if the creatures of the Ten Directions World had been slaughtered by Han Dong. Under this immeasurable murderous aura, even Onubis's heart couldn't help but pound, and there was a rare hint of fear in his heart.

Since he got the Killing Heart, Han Dong has never used it, and even deliberately suppresses it most of the time, for fear that he will sink into the killing and completely fall into the devil, setting off a monstrous killing catastrophe on the earth, and then the lives of the people will be miserable. But at this time, the Red Sea had already claimed to be a realm, and only he and Onubis were left among them. Even if he was enchanted, after killing Onubis, he would have enough time to sober up and not kill on a large scale.

Moreover, if he didn't use the power of the Killing Heart, he really wouldn't have the slightest certainty of victory in the face of Onubis, who was comparable to a half-step immortal.

"Boy, no matter what tricks you play, you will definitely die today. As time went on, the aura on Han Dong's body that made Onubis feel frightened became stronger and stronger, and if he continued to let it go like this, he didn't know what would happen in the end, so Onubis took action directly at the moment.

Now that the Red Sea had completely turned into the world of Onubis, at the thought of it, countless spears condensed from blood appeared in the entire sea of blood, mixed with overwhelming power, and shot towards Han Dong.

And at the moment when those spears were about to pierce Han Dong's body, Han Dong opened his eyes.

What kind of eyes are they?

Weird, tyrannical, scarlet-filled, bottomless like an abyss.

The spear that flew out of the sea of blood stood still in the air without warning in front of these eyes, and the spear body trembled, as if it had encountered an indescribable terror.

"I can't move my body!"

The moment Han Dong's eyes opened, Onubis's whole body exploded with scales, the huge dragon body became a whole circle larger, and his heart was only grabbed, and a severe cold called fear came from the depths of his soul, so that even his breathing was subconsciously lightened a lot.

Onubis has lived to the revival of his aura from four hundred years ago, has ruled the dark races, and has also fought in the Western God Realm, and the things he has encountered in his life are not insignificant, but the horror he faces today is unprecedented. At that moment, Onubis seemed to have turned into a chicken, and at this time he was facing an ancient murderer.

"Huaxia people......" Onubis shouted in front of him, he was afraid, even if the aura of death that had not appeared when he faced the four true gods of the God Realm back then, at this time, it seemed to surround his body, and he was like a giant hand pinching him.

"Roaring ......"

Han Dong's whole body was surrounded by blood and qi, and he let out an earth-shattering roar towards Onubis, and the blood spear that had been stagnant in mid-air was shattered, and then turned into blood and poured into Han Dong's body. After activating the Killing Heart, Han Dong had completely lost consciousness, and there was only one thought left in his mind, and that was to kill!

Kill all over the world!

This state of losing reason and emotion is called entering the demon in the Chinese cultivation world, and although it loses its humanity after entering the demon, its cultivation strength will increase explosively. Monks who are fortunate enough to be able to wake up from the demonic realm, whether it is your cultivation or combat power, have all been greatly improved.

In the Red Sea, the permeated blood qi also floated towards Han Dong at this time, and then it surged towards Han Dong as if it had been pumped away. This was originally the place where the Blood Dragon King was sealed, and it was also the place where the Blood Clan originated, every year the various tribes of the Blood Clan collected nearly 10,000 boys and girls from all over the world for sacrifice, in the past few hundred years, the lives that died in the Red Sea were more than a million, and the blood and resentment were beyond imagination. But as Han Dong opened the heart of killing, these accumulated forces were all attracted and converged towards Han Dong.

However, in just a few breaths, Han Dong was already covered by endless blood qi, and the aura emanating from his body also rose rapidly with the continuous use of blood qi. Unlike Onubis's previous insanely grown aura, Han Dong is breaking the bottleneck and recovering his strength.

But the more this happened, the more jealousy grew in Onubis's eyes. Compared to him breaking the seal, Han Dong broke through the bottleneck in such a short period of time that was even more terrifying.

In just a short period of time, the Red Sea had already become clear at a speed visible to the naked eye, and all the resentment and blood qi that had accumulated in the ocean for hundreds of years had submerged into Han Dong's body.

The killing heart hidden in Han Dong's heart was beating wildly, and the sound like thunder was like a dense drum beat at this time.

With the fall of Emperor Qin, the Killing Heart has been sealed in the Immortal Palace for thousands of years, and it has not devoured blood and resentment for a long time. At this time, the accumulation of hundreds of years of blood clan was suddenly devoured, and it was naturally extremely enjoyable.

And after such a rich blood qi was refined and purified by the Killing Heart, it continued to pour into Han Dong's body. So that Han Dong's cultivation can temporarily cross the top of the bottle, and even approach the upper limit of the earth.

Beyond the Red Sea, where the blood-colored space could not be enveloped, black clouds overwhelmed the city, and thunder flashed among them. At this time, the Heavenly Dao on Earth had already sensed the birth of a great threat in the Red Sea, and this situation of the convergence of the calamity clouds even enveloped most of the world, and almost all the cultivator organizations and transcendent organizations in the world could perceive the terrifying heavenly tribulation brewing in the black clouds.

"What the hell is going on here?"

Huaxia Wangxian Peak, whether it was the cultivators of the Earth Immortal Realm or Huaxia, all stopped the battle and looked at the clouds tumbling in the air in horror.

"Is this going to be someone who is going to cultivate the Earth Immortal Realm again? Is it the Earth Immortal Realm or the Huaxia Realm?"

Many cultivators are secretly speculating.

However, the great cultivators stationed on Wangxian Peak have already noticed that in addition to the abnormality in this tribulation cloud, the thunder light in the sky is very different from the thunder light that appeared in the previous thunder tribulation, the original thunder tribulation is only purple, at most it is only divided into light purple or dark purple, but this time the tribulation can clearly see gold and purple in the clouds, which shows that this heavenly tribulation is far from being comparable to the heavenly tribulation when he became an earth immortal.

"This is someone attacking the Heavenly Immortal Realm!"

The hearts of the cultivators above the Immortal Realm and the Huaxia Immortal Realm couldn't help but sink, the Golden Heavenly Thunder was the Nine Heavens Holy Thunder, which would not appear at all in ordinary times, and would only appear when the monks wanted to break through the limitations of the Earth's Heavenly Dao.

Whoever the cultivators of the Tribulation are today is not good news for either side.

In the Red Sea, in the midst of the scarlet nodules, Han Dong's crazy rising cultivation could be stopped when he was only one line away from the Heavenly Immortal Realm. Although the energy contained in the Killing Heart was definitely enough to send Han Dong into the Heavenly Immortal Realm, the energy released at this time had reached the limit that Han Dong's physical body could support.

Although as long as there is a little more energy, Han Dong can enter the Heavenly Immortal Realm, but when the time comes, it will inevitably attract the Heavenly Tribulation, and at the same time, the power beyond the carrying limit of the physical body will also cause indelible damage to it.

Although he is also a half-step immortal, Han Dong Zhenyuan's quality far exceeds the energy in Onubis's body, and the two fought, and Onubis did not have the slightest chance of winning.

Moreover, it was not only Han Dong who had changed, but the Sword of the Son of Heaven had also undergone great changes.

The Sword of Heaven was originally a domineering sword, but at this time, under the influence of the Killing Heart, it also absorbed a large amount of blood qi, and the seal on the sword body was completely broken, revealing its true appearance.

I saw that the sword body turned scarlet, like a sword condensed from blood, and at the same time, black runes full of killing intent appeared on it, which greatly increased the power of the Son of Heaven's sword.

After the power of the seal was completely awakened, the Son of Heaven Sword in Han Dong's hand had already reached the level of an immortal weapon, and it was much stronger than the previous battle of divine power in the hands of the Pope of Light.

At this time, Han Dong, who was completely enchanted, had nothing but killing in his heart, his body was stained with blood, he held the sword of the Son of Heaven in his hand, volleyed into the void, and walked towards Onubis, which was comparable to a mountain, step by step.

Although Han Dong's size was not remarkable in front of Onubis at all in comparison, every step he took at this moment increased the fear in Onubis's heart.
