A drop of Blood Essence flew out of Nie Tian's heart and dripped onto the Bone Blood Demon's heart.
Like a large sponge, the Bone Blood Demon's heart absorbed Nie Tian's Blood Essence the moment it touched its heart.
An overwhelming aura suddenly burst forth from within the Bone Blood Demon. Nie Tian could sense with great clarity that its heart had started pounding with unprecedented vigor.
Gasping with astonishment, Nie Tian sent a wisp of soul power from the fragmentary stars in his soul to conduct a thorough examination of it.
To his surprise, he saw thick, torrential blood pouring into the Bone Blood Demon's heart like flooding rivers.
At the same time, numerous sparkling spots started to form in its heart.
Then, the sparkling spots gradually came together, forming sparkling, crystal-clear chains.
It was just that the chains still seemed rather illusory and fragile.
Furthermore, the change only lasted a few seconds before it suddenly stopped.
A violent shudder ran through Nie Tian as he instantly realized what was happening to the Bone Blood Demon's heart. "Bloodline Crystal Chains!"
Even though the Bone Blood Demon's heart had remained intact after its death, the Bloodline Crystal Chains within it had long since been lost.
However, Bloodline Crystal Chains were the embodiment of a race's bloodline and carried their most profound talents and magics.
The green aura in his heart was the reason why he was able to keep awakening new bloodline talents.
Bloodline Crystal Chains were what formed that green aura. Therefore, it was those Bloodline Crystal Chains that made it possible for him to awaken bloodline talents and unleash bloodline magics.
According to his master, Wu Ji, the heart was as important to outsiders as the spiritual sea to humans.
It was said that, for high grade outsiders, even if they died, as long as their heart remained intact, after being given enough flesh power, they could still come back to life!
There even was a saying that tenth grade outsider monarchs could reform bones, reattach meridians, regenerate flesh, and return to life by relying on just one drop of Blood Essence, and they would be able to recover their strength through time!
The Bone Blood Demon had been at the eighth grade before it had died.
Unlike those outsider monarchs, it couldn't return to life by just relying on one drop of Blood Essence.
Even so, Bloodline Crystal Chains had reappeared in the Bone Blood Demon's heart because of that drop of Nie Tian's Blood Essence.
"Apparently a drop of Blood Essence is far from enough," Nie Tian thought to himself.
Nie Tian finally understood why the Bone Blood Demon had yearned for his Blood Essence so much.
Once the Bone Blood Demon recovered its Bloodline Crystal Chains, it would be able to use the Bonebrutes' bloodline talents and magics again.
Before, when the Bone Blood Demon had fought, it had only relied on its indestructible body and the Blood Refining Incantation the Blood Sect had forcibly infused into it.
Due to the destruction of its Bloodline Crystal Chains, it hadn't been able to use the bloodline talents and magics that made Bonebrutes truly powerful.
"I need you to recover your battle prowess!" Nie Tian exclaimed inwardly. "You'll only be able to display your full power when you can use your race's bloodline talents and magics!"
Without any hesitation, he summoned all of the Blood Essence that contained the profound truths of life from within his heart.
One drop after another, they dripped onto the Bone Blood Demon's heart.
After taking in the remaining nine drops of Blood Essence, the miraculous change started again.
More and more illusory, sparkling spots appeared and came together in the Bone Blood Demon's heart as torrential blood entered its heart.
Nie Tian focused all of his attention on its heart.
Under his gaze, translucent and sparkling Bloodline Crystal Chains gradually came to form, one after another.
Nie Tian expected that the process would take a fairly long time, and he felt exhausted after losing those ten drops of Blood Essence.
Nie Tian rose to his feet and walked to the seventh grade Stoneman's corpse, where he launched Life Drain and started channeling its rich flesh power into himself.
Moments later, flesh auras that had expanded dozens of times over returned to him.
They followed his meridians to his heart, where they were gradually refined into new drops of Blood Essence.
As the Bone Blood Demon reformed its Bloodline Crystal Chains with his Blood Essence, he recovered his Blood Essence one drop after another with the flesh power he absorbed from the seventh grade Stoneman's corpse.
Later, as he regenerated the ten drops of Blood Essence in his heart, there was still a copious amount of flesh power left in the seventh grade Stoneman's corpse.
He examined the Bone Blood Demon's heart and discovered that the changes had stopped again.
Only a third of the fine, sparkling Bloodline Crystal Chains had grown solid and strong.
Most of the Bloodline Crystal Chains still seemed illusory and fragile. Even though they were also flickering with bright light, it seemed that they could go out at any moment.
"Damn! That's still not enough!" Nie Tian cursed inwardly as he tightened his lips and sent the newly-generated ten drops of Blood Essence into the Bone Blood Demon's heart as well.
As soon as they entered the Bone Blood Demon's heart, all of the illusory Bloodline Crystal Chains lit up like glorious stars in the highest heavens. An unfathomable change happened again.
The chains of bright spots gradually materialized, as if they were morphing into chains made of tiny gems.
Like this, the Bone Blood Demon slowly reforged its Bloodline Crystal Chains with the help of Nie Tian's Blood Essence.
However, Nie Tian was aware that even those new ten drops of Blood Essence wouldn't be enough to finish the reforging process.
Therefore, he went back to absorbing flesh power from the seventh grade Stoneman, generating new Blood Essence, and using it to reforge Bloodline Crystal Chains for the Bone Blood Demon.
Time passed bit by bit...
After two more rounds, Nie Tian had infused twenty more drops of Blood Essence into the Bone Blood Demon's heart.
During this process, he no longer paid attention to the changes in the Bone Blood Demon's heart. Instead, he focused all of his attention on absorbing flesh power and generating Blood Essence.
That was when he realized that he had almost completely drained the seventh grade Stoneman's corpse of its flesh power, and thus opened his eyes.
Eyebrows furrowed, he examined the Bone Blood Demon with a wisp of soul power from the fragmentary stars in his soul.
He discovered that the numerous fine Bloodline Crystal Chains in the Bone Blood Demon's heart had finally become solid and resilient. Not a single one of them seemed illusory anymore.
Meanwhile, the Bone Blood Demon started to release a strange aura that seemed to be able to silence everything in heaven and earth.
A series of questions entered Nie Tian's mind.
"Now that the Bloodline Crystal Chains have been restored to the Bone Blood Demon's heart, it can probably use bloodline talents and magics in battle again, right?
"How high is its current battle prowess?
"Will it be able to contend against a late Soul realm expert?"
After all, the Bone Blood Demon was just a puppet with an incomplete discarnate soul. It had lost its memories of the past and many profound things in its soul.
All it could do now was follow Nie Tian's orders and fight whoever it was told to.
Even so, he had a feeling that the Bone Blood Demon had changed. It had become stronger, but he didn't know how that was. He would have to test its current strength through a battle with a formidable enemy.
However, there was one thing he was sure of: after helping the Bone Blood Demon reforge its Bloodline Crystal Chains with a large amount of his own Blood Essence, his connection with it had become closer and more profound, even though he didn't know what this would change.
At that moment, something suddenly occurred to him. "Bloodline Crystal Chains reformed in the Bone Blood Demon's heart after it was infused with my Blood Essence. I have another treasure that also possesses a 'heart'!
"The Flame Dragon Armor's Blood Core, in its essence, is also a heart.
"If my speculations are correct, the Blood Core is probably a shriveled flame dragon's heart!
"If the Bone Blood Demon could recover its Bloodline Crystal Chains after getting my Blood Essence, would similar changes happen to the flame dragon's shriveled heart after I infuse it with my Blood Essence?"
He knew that he could channel two types of power from himself to the Flame Dragon Armor: flame power and flesh power.
Furthermore, the Flame Dragon Armor's performance in battle would improve after gaining these two types of power from him. He could still remember that when he had worn it in battle, it had absorbed wisps of flesh power from him continuously.
Blood Essence was the essence of his blood. Each and every drop contained a shocking amount of flesh power.
Not just that, but the profound truths of life lay within his Blood Essence, which could work miracles. The reforming of the Bone Blood Demon's Bloodline Crystal Chains was proof enough of that.
"I can probably strengthen the Flame Dragon Armor with my Blood Essence!" he thought to himself.
However, after pondering for some time, he eventually decided to forgo that thought for the time being. After all, he wasn't sure how long it would take for him to test that theory.
"Let's go," he said to the Bone Blood Demon. "I've spent a large amount of my precious Blood Essence reforging your Bloodline Crystal Chains for you. Now it's time to test whether that was worth it."
With these words, he stepped into the teleportation portal and returned to the Dong Clan.
