In order to ensure the success of the Heavenly Blood Array, Rin Yu also specially mixed a drop of essence blood. Sperm blood can be different from ordinary blood, accumulating blood essence, and losing too much can be life-threatening. The energy of essence blood is naturally not comparable to ordinary blood, if it is essence blood, one drop is enough to support the Heavenly Blood Array.

Tianlan was unwilling to waste the extra dragon blood, so he packed it in a special jade bottle, and it was a full ten bottles. Dragon blood is a good thing, in addition to the array, alchemy refining tools can be used, and it is often the best elixir spirit weapon that only needs dragon blood. With it, Tianlan can even make some extinct pills reappear in the world! Of course, there are other prerequisites for this......

Next, it's time to officially arrange the Heavenly Blood Array. This is the first time Tianlan has tried this formation, and he is still arranging a formation in the air. Naturally, there was no such opportunity before, even if he had never had it in his memory, all his cognition of the Heavenly Blood Array was from books. This time the formation is the first time to set up, and it is only allowed to succeed, not to fail, and there is still a little bit of pressure psychologically, but it is still indifferent on the surface.

He stood on the dragon's back, flipped his right hand, and suddenly a handful of spirit stones appeared. Taking a deep breath, the formation of the Heavenly Blood Array appeared in his mind, and the rays of light in his memory were infinitely magnified, overlapping with the picture in front of him. The space became fragmented in his eyes, and the fine and dense lines outlined a mysterious array, sometimes like a dragon's horn, sometimes like a dragon's tail, sometimes like a dragon's eye, and sometimes even like a whole dragon.

In an instant, the entire formation went through in his heart. If anyone is there, they will definitely be able to see his current eyes, the pitch-black pupils are covered with a layer of silver-white halo, and there are constantly flashes of light, which is extremely peculiar.

Finally, he threw out the first spirit stone in his hand, stopped at a position accurately under the control of his spiritual power, and then used his dragon qi to make it float in mid-air without falling.

Then, his movements became faster, followed by the second, third, and fourth...... Each spirit stone has its own fixed position, which at first glance seems to be irregular, but in fact, it is faintly formed into a sphere, enveloping Tianlan, Rin and the two stones.

Tianlan threw out the last spirit stone in his hand, a full hundred, scattered in the air, exuding a faint light, like the stars of the polar night, and the fireflies flowing under the moon.

He exhaled lightly, not daring to let up, and focused again, knowing that what was next was the key.

He stared at the dragon's blood wrapped in dragon energy. At this time, only a small part of the dragon's blood remained, and most of it was collected by him. But since there is a drop of essence blood in this small part, it is definitely rich. He frowned, biting his finger and mixing his own blood into the dragon's blood. The drive of the Heavenly Blood Array requires the blood of the person who sets it up, and most of the ancient magic circles do so, and sometimes it also requires essence blood. In this way, the formation can only be driven by the person who sets it up, and cannot be faked by others.

His fingers danced slightly, and when he slashed through the void, he would bring out a trace of green light, and the dragon's blood would be divided into wisps and wisps under the guidance of the blue light, and he went straight to the various spirit stones. In fact, the trajectory of dragon blood is not exactly a straight line, but a slight curve, and all the trajectories are connected to the appearance of a dragon scale.

That small half of the dragon's blood was suddenly reduced by half, and after the dragon's blood was injected into the spirit stone, the white spirit stone turned into a dark gold, similar to the dragon's blood. Most of the energy of the Heavenly Blood Array comes from dragon blood rather than spirit stones, and the number of spirit stones is not high, a hundred is enough.

He drove the remaining dragon blood containing essence blood to be in the center of the formation, and several mysterious gestures changed one after another in his hands, and the speed of the movements was dizzying! At the same time, the dragon's blood glowed, and six dark golden magic circles appeared in six directions, front and back, up and down, left and right, each magic circle was different, it was six dragons flying in different postures.

The black dragon Rin was greatly surprised, and shouted in a low voice, "This is ...... The Six Great Dragon Kings are really magical, and they can actually find the totems of the Six Great Dragon Kings as the base ...... the formation."

Tianlan heard it, but ignored Rin's words, because he was in a little trouble now. Originally, he induced the power of dragon blood and used spiritual power to control its output according to the established trajectory, and the process was exactly right. The problem is in the dragon's blood......

Generally speaking, the source of the power of the formation is the stronger the better, so that the formation itself will last longer and the effect will be better. Tianlan didn't care about the excessive amount of dragon blood at first, but when it came time to actually implement it, he realized that he had ignored this serious issue.

The dragon clan is most proud of the dragon body, the dragon blood is a part of the dragon body, its power is far greater than human imagination, it is not something ordinary people can control. Rin Yu is also a black dragon, the rarest and most powerful of the dragon clan. He overdrew his strength as an array eye, but he did not hurt the dragon body, and the power of the dragon's blood did not decrease. The worst thing is that Rin Yu also took out the essence blood, if the human swallows this drop of essence blood, he will definitely explode and die, even if he gets it, he can't stand it.

Rin's full support, coupled with Tianlan's neglect, caused the power of the dragon's blood to be too strong now, and he couldn't control it.

There were beads of sweat on Tianlan's forehead, and his back was already soaked with sweat. Can't stop ...... He did his best to suppress the dragon's blood of the riot, trying to disperse it. He is now in a dilemma, and if he fails, the powerful force of counterattack can kill him in an instant, and there is no chance to start over.

The power of the dragon's blood is like a frightened elk, scurrying around. Although Tianlan's spiritual power was strong, it was no match for the black dragon's essence blood, so he had to change his countermeasures and turn suppression into soothing. His spiritual power contains the gentleness of the wind, and under the special drive, it actually has a calming power.

The power of the dragon's blood slowly subsided under the blowing of this spring breeze, like a naughty child tired of playing and falling asleep.

The Heavenly Blood Array began to operate normally, and the six huge Dragon King Totem Arrays rotated rapidly, colliding with the original formation space with fierce sparks.

"Senior, it's now!" his voice was indescribably tired, but his words remained firm.

With a swing of the dragon's tail, it slashed towards the moonstone, and under one blow, the moonstone suddenly shattered into three parts.

The intense red light surrounded the black dragon, the Nine Life Beads, and the shattered moonstone, and the Heavenly Blood Array was activated......

A dragon roar shook the sky, and even Ye Yi and the others, who were tens of thousands of meters away, could hear it clearly. Everyone's hearts were in their throats, whether the Heavenly Blood Array could succeed or not, even Tianlan, who was the arranger, was not fully sure, could the effectiveness of the array be transferred to the broken moonstone?

Nangong Mingjing, Ye Yi and the others, who had been watching the whole process, saw that the black dragon far away in the sky suddenly disappeared in a brilliant red ball of light. The black night suddenly cracked around the red ball of light, and a huge crack filled the sky in an instant.

Immediately afterwards, the sky shook, the mountains collapsed, the rocks of the cliff shattered into pieces and fell, and the sky tore white traces, as if the original film was broken, revealing the original appearance of heaven and earth.

Everyone fell to the ground and hugged their heads, and they were dizzy from the earthquake. After a long time, the tremors subsided, and everyone looked up again, and saw that the surrounding scenery was still in that valley, but finally the rain had cleared, the bright sun was shining, the black fog was gone, the blood moon was gone, and they returned to the real world, and the cheers were like thunder.

But a few people were not happy in the slightest, but looked nervously at the sky, looking for something.

Blue sky and white clouds, fresh breeze gusting, it is indeed a rare good weather. Only, where is the person they are waiting for?

"Hey, why didn't that black dragon bring Tianlan back?" Ye Yi poked the iron sword to the ground, seemingly in a bad mood, but it was not good to disturb everyone's excitement. "Did you fail......

"Impossible!" Xiaotang looked at the sky, folded his hands, and said in a voice that was almost self-talking, "No...... Childe will not fail...... It must be...... It must be that the black dragon is flying too high, even if it flies back, it will fly for a while......"

"Second uncle, what about Big Brother Tianlan?" Nangong Kui asked Nangong Mingqing weakly.

Nangong Mingqing shook his head and said nothing, only looking at the sky quietly. Nangong Kui also followed his gaze towards the sky, and at this time he couldn't help but pray that the terrifying black dragon would appear soon. He promised...... This time, no matter how terrifying the black dragon was, he would definitely not faint again...... I beg you to come back soon......

Nangong Mingjing, Qin Zhongjie, Pu Le and others followed the mercenaries to share their excitement, but in addition to the excitement, many people couldn't help but occasionally look up at the sky.
