"Hmm." Xiao Yan nodded, clenched his teeth, and forcibly endured the tearing pain, and under this sharp pain, he could feel that the blood in his body was disappearing rapidly, and an extreme feeling of weakness quickly spread out of his body, making his eyelids can't help but droop a little.

"Can't fall asleep! Otherwise, the old blood will not be cleaned, and the power of the bloodline will not be able to be exerted to the extreme, and the current people of the Xiao clan will not be able to use gentle means to activate it like other races, and can only take the most brutal way. Seeing Xiao Yan's gradually drooping eyelids, Xiao Xuan shouted fiercely.

Hearing Xiao Xuan's screaming, Xiao Yan suddenly shuddered, and hurriedly concentrated, suffering under the severe pain and extreme weakness.

Xun'er, who was next to the blood pool, saw Xiao Yan suffering like this, and her jade hand couldn't help but clench it, and she felt a little distressed in her heart.

"Alas, in extraordinary times, we can only do extraordinary measures." Xiao Xuan sighed, and then sat down cross-legged next to the blood pool, the time required to exchange blood was not short, that is to say, the pain that Xiao Yan endured would also have a long time.

In this quiet hall, time flies by, and in the blink of an eye, seven days have passed, and during these seven days, Xiao Yan's body has been immersed in the blood pool, and with the blood clearance of these seven days, Xiao Yan has almost become skinny and bone-like, and his face is terrifyingly pale, if it weren't for the faint breath between his noses, I am afraid he would not have regarded him as a living person.

Next to the blood pool, Xun'er witnessed the changes in Xiao Yan in the past ten days, but her heart was like a knife, and she watched her beloved become like this step by step, I am afraid that no one will feel good in her heart.

However, for Xiao Yan's change, Xiao Xuan is relatively calm, but there are still some worries in his heart, the exchange of blood also has some risks, at this time, the person who exchanges blood is the weakest time, if a mind is unstable, I am afraid that he will really swallow the last breath from the state of frequent danger, at that time, it is really from the state of one breath to the dead.

"Boom!" And just as the two of them were waiting in such complicated moods, a slight sound suddenly came out of the calm blood pool, and then blood bubbles emerged from the blood pool, and finally exploded, and at the same time, a blood-colored vortex took shape, and the center of the vortex was Xiao Yan, who was as thin as a skeleton.

"The transfusion was successful...... Next, he only needs to infuse the blood with the power of the bloodline into his body, and Xiao Yan will be able to have the power of the bloodline of the Xiao clan again! Seeing such a change, Xiao Xuan also breathed a sigh of relief, and his hands formed a seal like lightning, and a blood-colored brilliance shot into the pool of blood.

"Gollum!"

"Gollum!" With the injection of this blood-colored brilliance, the blood pool boiled violently, and blood bubbles continued to rise, and at the same time, a trace of strange blood-colored liquid was also separated from the pool water, and finally climbed up Xiao Yan's body, along the pores, and continued to perfusion.

As these blood-colored liquids full of strange energy entered Xiao Yan's body, his originally extremely pale skin gradually surged with a trace of ruddy, and the shriveled skin slowly began to rebound.

Seeing this gradually improving scene, Xun'er also breathed a sigh of relief, and said softly: "Senior Xiao Xuan, in this blood pool, there are still some of the energy you sealed back then, if all these energies are absorbed by Brother Xiao Yan, it should make his strength skyrocket, right?" ”

"Hmm!" Xiao Xuan nodded, glanced at Xun'er, and said with a smile: "I know what you're thinking, this kind of strength that relies on external forces to skyrocket, if it is not well controlled, it will become a huge obstacle to the promotion of Dou Sheng in the future, but this truth, Xiao Yan should also be clear, so he will choose the most rational way...... Trust him. Xun'er nodded silently, she was indeed a little worried in her heart, the energy left by Xiao Xuan would inevitably be extremely huge, even if it was impossible for Xiao Yan to soar to the peak of Douzun all at once, in recent times, Xiao Yan's strength progress was already very terrifying, if this was the case, then Xiao Yan's chances of becoming a Dou Sheng in the future would become very small.

From a long-term point of view, this is extremely uneconomical, but this worry is not too strong, she knows Xiao Yan very well, the latter has always been sensible, and he is also quite cautious about this kind of external power, which can be seen from the fact that he is an alchemist, but rarely allows himself to take those pills that can instantly increase his strength, so this time, he should also be prepared in his heart.

"Next, let's wait for the blood exchange to be completed!" Xiao Xuan said softly, even if he slowly closed his eyes, Xun'er on the side nodded slightly, stared at the blood pool again for a while, and only after seeing no abnormal changes did he enter the cultivation state with a little relief.

The ancient hall was silent, only the gurgling sound of blood bubbles constantly echoing in the hall.

"Gollum!" In the blood pool, the blood bubbles are constantly rolling, and now Xiao Yan's skin has returned to its previous appearance, looking full of vitality, outside his body, he can vaguely see countless blood streaks gushing out, and finally poured into his body, and with this infusion, Xiao Yan's breath is also gradually climbing.

"Next, let's wait for him to completely inherit the energy I left behind, this time will not be short, during this time, you can meditate and cultivate here, the energy here is the richest place in the Heavenly Tomb, cultivating here, you can get good results!" Xiao Xuan glanced at the blood pool, deep in the blood pool, a stream of energy that was so rich that it was almost substantial was pouring into Xiao Yan's body, and he knew that the current Xiao Yan was already beginning to absorb the energy he left behind.

"Hmm." Xun'er nodded slightly, her beautiful eyes stared at Xiao Yan in the blood pool for a long time, and after seeing that there was nothing wrong, she slowly closed her eyes with confidence and entered the cultivation state again.

About ten days later, Xiao Yan in the pool, the speed at which the aura on his body climbed suddenly decreased.

However, at this time, he had already grown to the peak of the Seven-Star Douzun, and it seemed that he was only one step away from being able to enter the level of the Eight-Star Douzun.

"Boom!" At a certain moment, the aura on Xiao Yan's body skyrocketed again, and he directly broke through to the level of the Eight-Star Douzun.
