"Hoo !!" A huge stream of black dragon flame erupted from the dragon's mouth.

The flames hit the mountain at the top of the cave.

"Bang Bang Bang !!" The sound of a mountain rock collapsing sounded, and in less than a few seconds, the huge hole was blocked by the sliding mountain stones, and the cave was instantly dark, without a little light, but this was nothing to Li Li, zombies have the ability to see at night.

But at this time, Li Li, the state is not good, three days ago, he cut the artery of his wrist, driving the blood in the body to continue to discharge, the cheats say, in the repair, to try to release the blood in the body, so that the effect of repair can be more obvious, and, if the ferocious animal used to exchange blood is strong enough, it may even lead to zombie mutation, and the strength is further enhanced.

In the body of zombies, blood is divided into two kinds, one is the ordinary blood that circulates in the blood system, and the other is the essence blood hidden in the deepest part of the bloodline, ordinary blood provides the energy for the zombie to move, and the essence blood is the root of the zombie bloodline and strength.

Li Li persisted in the process of bloodletting for three days, and now, it has reached his limit. If Li Li was just like a dry corpse before, then now Li Li's image is a real 'skin and bones'.

Li Li held on to his consciousness and controlled the dragon to cut the arteries of his front paws.

"Roar!" The dragon let out a roar of unknown meaning, and Li Li could feel the resistance in its emotions, but in the end, the dragon still used one claw to cut the artery that cut the other.

"Puff !!" Hot dragon blood spurted out from the dragon's claws and poured onto Li Li Chiguo's body.

"Clam~~" Li Li let out a comfortable low roar from his neck. When the dragon's blood was poured on him, it was like a tired person slowly sinking into a hot spring, as if the pores of his whole body were opened.

Zombies, especially vampire zombies, the more powerful the creature's blood buffs the zombie.

Li Li opened his mouth and gulped down the dragon's blood.

After about thirty seconds, the dragon let out a low roar and withdrew its claws, the wounds on which quickly healed.

And Li Li, who was in front of the dragon, lay down with peace of mind. At this time, he was lying in a stone pit about half a meter deep, and his whole body was immersed in dragon blood.

Time passed slowly, the dragon blood in the stone pit decreased little by little, and Li Li's body was also undergoing rapid changes, the zombie essence blood in Li Li's body absorbed the energy in the dragon's blood, while assimilating the dragon's blood, and recasting the blood circulation system of the blood.

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

In the following time, Li Li would control the black dragon to release a certain amount of blood every day to enrich the 'blood pool', and this kind of days lasted until seventeen days later, when Li Li once again controlled the dragon to release the dragon's blood, but there was no response.

"Huh?" Li Li's vague consciousness cleared up a little, and Li Li once again controlled the dragon to release the dragon's blood, but still did not get a response.

Li Li could sense that the dragon was still beside him.

The next moment, in the pitch-black cave, a depression in a boulder, a blood-colored human figure slowly sat up from the pulp-like pool of blood.

Li Li ignored the plasma attached to his body and opened his eyes to look at the pitch-black dragon in front of him.

At this time, the giant dragon presented in front of Li Li's eyes was no longer like the appearance of the spirit dragon and the tiger before, the dragon was dying, a pair of huge dragon wings hung weakly on the ground, his eyes were slightly closed, and even the sound of breathing was faint and very faint, if it weren't for Li Li's ability to sense living creatures, he wouldn't even be sure if the dragon in front of him was still alive.

Li Li frowned slightly, looking at the appearance of the giant dragon, there was a faint unbearability in his eyes, but he was quickly suppressed by him.

Li Li knew that the Blood Sacrifice Alchemy Technique could not be interrupted, otherwise his previous efforts would be in vain, not to mention turning back into a human, the zombie bloodline might collapse directly, and even if it didn't collapse, it would be inevitable that his strength would be greatly reduced.

Li Li slowly crawled out of the pool of blood, stepped on the bloody footprints, and walked towards the dying black dragon step by step.

Li Li stretched out his hand and touched the black dragon's scale armor, and then, no longer hesitating, he walked to the bottom of the black dragon's neck, close to the position of the heart, Li Li could sense the location of the black dragon's heart.

Li Li stretched out his pitch-black claws and stroked a scar on the black dragon's body, the scar had not completely healed and was scabbing over, which was a wound caused by Li Li once controlling the black dragon's self-harm.

Before starting the blood sacrifice, Li Li had already expected this situation. After all, the Blood Sacrifice Law says that it ranges from January to March, so who knows how long the black dragon can last?

"Puff Puff !!" Li Li's palm thrust violently, directly into the black dragon's wound, scarlet blood splattered out instantly, and the black dragon's body spasmed slightly.

Li Li controlled and did not let the black dragon move.

Immediately afterwards, Li Li inserted his two hands into the wound of the black dragon, and directly tore open the wound that had healed little by little, this wound was about two meters, Li Li tore more than one meter, and then, Li Li drilled directly from the wound into the black dragon's body.

In his body, Li Li crawled towards his heart little by little.

..........

"I see." In the black dragon's body, Li Li looked up at the huge heart of red and blue intersecting in front of him.

This is the heart of the black dragon, the heart was originally supposed to be red, but now, on the red heart, there are blue lines of different thicknesses, like meridians, coiled around the heart of the black dragon, at this time, the heart is still beating.

For the first time, Li Li remembered the heart that once exuded fluorescent blue.

The next moment, Li Li crawled in front of the dragon's heart, and this heart alone was about two meters and a half in diameter.

"Knock knock! Knock knock! Knock knock! ....." The huge heartbeat echoed in Li Li's ears.

The next moment, Li Li stretched out his right hand, and the scale armor on his palm gently slashed the black dragon's heart, and a large amount of blood spurted out.

Li Li wasted no time, quickly cut a huge rift, and then stuffed his body into it to block the splattered blood. The next moment, a faint film of blood appeared on the surface of the black dragon's heart, completely blocking the wound of the heart.

Li Li was immersed in blood, his eyes were dark, and he could only hear "Knock knock!" in his ears. Knock knock! A loud echo.

The tenacious life of the S-class mutant beast made the black dragon's heart continue to beat, providing Li Li with a steady stream of blood energy.

Time passed little by little, during which the black dragon regained some energy and wanted to go out to find food to recover from his injuries, but was stopped by Li Li in his body.

Li Li didn't want to take the risk, in case the black dragon went out and encountered a hostile S-class mutant beast, wouldn't it be a ride for him together.
