The red light flashed in his hand, and a red dragon with a length of more than ten zhang appeared in front of Lei Yu, this red dragon coiled into a snake array, and a pair of sharp eyes stared at Lei Yu, as if threatening him, giving people a fierce feeling.

At the same time, a powerful force emerged, and it seemed that the red dragon in front of him was not just like this, but a great mountain, out of reach.

This is the red dragon, and it is also the dragon core of the dragon vein of Wanfo Mountain, in order to get this thing, Lei Yu risked his life, but after getting it, he knew for the first time that he had done the right thing this time.

The core of a dragon vein is the dragon core, and the amount of power contained in it is amazing, if he can refine this red dragon and seize the power of the red dragon, it will definitely be beneficial to him without harm. Of course, the most important thing to note now is that this red dragon has become extremely fierce and not easy to absorb.

A low dragon groan sounded, and the red dragon seemed to be a little unwilling, but at this moment, the red dragon had lost almost all of his ability to act, although there was no harm on the surface, but Qin Yang, the prince of war, was extremely hurt, and he was unable to exert his strength.

"Now that you are the turtle in my urn, do you still want to escape from my hands! Lei Yu sneered, and a powerful aura permeated from his body.

Under this breath, the void shook, and an infinite storm suddenly rose above the silent planet, and all of a sudden, the sand and rocks flew away, and it was a mess.

"Refining the Red Dragon, for my use!" Lei Yu roared, slapped out a palm, and under the loud sound of "boom", the red dragon trembled, and a breath containing endless ferocity spread, and there was a feeling that made Lei Yu face a wild beast.

The red dragon had completely changed under the blood of more than a dozen immortal thunder stage powerhouses, and the strength of its whole body had become evil, ferocious, and bloody, and in just an instant, Lei Yu felt that he was facing an endless sea of corpses and blood.

It was the will of the red dragon that resisted, and he didn't want to be refined by Lei Yu, but the red dragon was ruthless, and the thunder feather was more ruthless than the red dragon.

After the battle with Qin Daotian, although he suffered a heavy blow, he also received great benefits, and in these five years of cultivation, he has also reached a higher level, and he is only half a step away from being promoted to the Immortal Thunder Period.

An even more ferocious momentum erupted from Lei Yu's body, in this momentum, in addition to the boundless evil qi, there was also a powerful majesty, this majesty came from the will that did not flinch against Qin Daotian, far more powerful than the red dragon.

"Boom!" A loud bang sounded, and Lei Yu slapped another palm on the red dragon's body, and suddenly, the red dragon let out a series of miserable wails, and his body trembled violently.

A red cloud rose up, and the surface of the red dragon began to become a little illusory, and its body did not seem to be its own body, but became a different kind of power.

This is the real red dragon, it itself is a kind of strength, it just has some spiritual intelligence, it is not a living creature at all, and now Lei Yu refining the red dragon is to completely destroy this trace of spiritual wisdom, so that this red dragon can truly become a mass of energy.

"Groaning ......" The high-pitched dragon chant of the red dragon came and went in the "Tibetan Heaven Great Array", but it did not have the slightest effect, the "Tibetan Heaven Great Array" had the ability to hide the sky, even if the red dragon's voice was loud, it would not be able to transmit the "Tibetan Heaven Great Array", let alone attract the attention of others.

The refining continued, Lei Yu's hands were like electricity, and he kept shooting, and the red dragon's body continued to shrink, leaving only more than five zhang left, and the physical body on its surface had disappeared, leaving only a red ball of light, which contained boundless power.

Suddenly, a golden light emerged, and in this light there was a noble, arrogant, and sacred aura, as if a true dragon was coming to the world, unpredictable.

"The mark left by Qin Daotian, has it finally appeared today?" For this golden light, Lei Yu was not surprised, he already knew that Qin Daotian had left a mark on the red dragon, but because of his lack of strength, he still had no way to find the red dragon.

Today, this mark felt that the red dragon was about to die, and finally couldn't help but escape, and this also gave Lei Yu a great opportunity.

The golden light jumped into the sky, turned into a golden dragon, and headed towards the sky, but Lei Yu would not give him this opportunity, and with a flick of his fingers, a muddy yellow finger shot out, piercing the void, and hitting the golden dragon fiercely.

With a soft "bang", the golden dragon turned into ashes, and at the same time, in the palace of the Great Shang Dynasty, Qin Daotian, who was closing his eyes and recuperating, suddenly opened his eyes, and a sharp light crossed his eyes: "The red dragon has appeared!"

A golden streamer quickly jumped out of the palace, and when he looked at it again, Qin Daotian had disappeared without a trace.

"Thinking about it, Qin Daotian should know that his mark has been broken by me, and he is coming in my direction. However, there is no accurate location, it is not easy to find me in this vast sea of stars, and with this 'Hidden Heaven Great Array', let Qin Daotian look for it slowly!"

Lei Yu smiled confidently, without the slightest hint of nervousness, the sea of stars was boundless, even with the cultivation of Qin Dao Tianyuan Thunder Period, it was difficult to find him, he didn't need to worry at all.

The red dragon is getting smaller and smaller, and its spiritual wisdom is gradually dissipating, gradually turning into a red light cluster with a radius of a hundred zhang, and a powerful force surges out, even with the concealment ability of the "Hidden Heaven Array", it seems that it is a little unsupportable.

This is the power of the dragon core, containing the power of a dragon vein that has been gathered for millions of years, terrifying to the extreme, if it really breaks out, this dead planet will be completely destroyed.

"Slash!" Lei Yu shouted, and pointed like a knife, slashing at the red dragon's dragon head, in an instant, accompanied by a painful hiss, the red dragon's most reluctant trace of wisdom completely dissipated, and since then there has been no red dragon, only this mass of power that no one controls.

"Without further ado, just take this opportunity to survive the Immortal Thunder Tribulation!" A flash of brightness flashed in Lei Yu's eyes, and without hesitation, a powerful suction force emerged from his body, devouring the red light cluster left behind by the red dragon.

Wisps of red light poured into Lei Yu's body, and then flowed into the Tianqiao acupoint, at this moment, the Tianqiao acupoint was filled with infinite power, wave after wave, like a vast sea, boundless.

This force is constantly impacting the Tianqiao acupoint, so that Lei Yu's thunder baby is a little unbearable, and it seems that it may break at any time, which means that the Tianqiao acupoint has reached a limit, if you don't break through the Tianmu acupoint and promote to the Immortal Thunder Period, Lei Yu will die because the thunder power is too full and explodes.

So this time the impact of Lei Yu did not have the slightest way out, death or life, it was all between Lei Yu's thoughts.

The power of the red dragon is endless, constantly gathering in Lei Yu's body, and the Tianqiao acupoint can no longer meet the needs of these thunder forces, and begins to pulse along Lei Yu's whole body to the Tianmu acupoint.

Tianmu acupoint, as the name suggests, is called the eye of heaven, if you can break through the acupoint of Tianmu, it is equivalent to having a pair of heavenly eyes, from now on you can use the naked eye to view the laws of this world, master the law, achieve immortal thunder, and become a real immortal.

And the place where the Tianmu acupoint is located is also very different, he is located in the center of the forehead, the same as the location where the Tianmu is located, it can also be said that the Tianmu acupoint is the Tianyan, once it breaks through the Tianmu acupoint, it is equivalent to opening the Tianmu and opening the path of the law.

"Boom!" As if it was thunder, a large cloud suddenly appeared in the originally yellow sky, and there was a thunderous roar, as if it was about to tear the entire sky apart, and the boundless power of the sky descended, even with the thunder feather, he felt a heartbeat.

It was the true power of the sky, and clouds covered the sky, layer after layer, and there were silver thunder snakes flashing out of the clouds, splitting the earth, turning hills and mountains into ashes.

Lei Yu's divine thoughts spread out, and at this glance, even if it was his cultivation, he couldn't help but gasp, only to see that above this star, all within a radius of 100,000 miles were shrouded in a layer of dark clouds, and this was not the extreme, there were more dark clouds that were constantly generated, according to this situation, it would not take long for this star to be shrouded in dark clouds.

Perhaps, this cloud will not be satisfied with this one star, but will also expand towards this star field, and finally envelop this star field in it.

"Damn, kid, what did you do to hurt the heavens and reason, there would be such a strong Immortal Thunder Tribulation, and the clouds were all over the starry sky of the universe, even the 'Nine Shadows Emperor' had never experienced this situation, are you sure you want to break through to the third order of the Immortal Thunder Stage in one fell swoop?"

Yin Ming asked with some concern, after all, his cultivation was higher than Lei Yu, so he could naturally see more things than Lei Yu.

"Senior, don't worry, this time I will definitely be promoted to the third order of the Immortal Thunder Stage!" Lei Yu said firmly, still constantly absorbing the power of the red dragon, his face did not have the slightest fear, calmly looking at the clouds that permeated the starry sky of the universe.

Even though the power of the sky was amazing, his heart was calm, and there was not the slightest ripple, as if it was not him at all, but someone else.

In order to promote the Immortal Thunder Period, he has made sufficient preparations, not only with the help of the Red Dragon, but also with the first layer of the treasure of the "Nine Hidden Treasures", plus its own foundation is also extremely solid, if he can't survive the Immortal Thunder Tribulation, he has nothing to say.

At this moment, a thunderbolt like a mountain slashed out from the layers of clouds, like a silver snake dancing wildly, and directly hit Lei Yu, and the immortal thunder tribulation finally began.
