Inside the secret chamber, Lin Feng took out the Heavenly Demon Puppet Secret Technique he had exchanged with the Demon Ancestor of Demon Flame Valley and began studying it again.
Nearly two months had passed since he obtained the technique, so Lin Feng naturally had a thorough understanding of it. He was simply reviewing it as usual, checking for any omissions or gaps.
Before long, Lin Feng stored the Heavenly Demon Puppet Secret Technique in his storage ring. Then, from among the many storage rings on his wrist, he selected one containing the materials for refining the Heavenly Demon Puppet.
"For the first attempt, to be on the safe side, it's best to use a Dou Huang-level body first!"
Lin Feng said calmly, stroking his chin. "After all, there's only one Dou Zong-level body so far, and that was the gift from that kind-hearted Scorpion Bi Yan. If we fail, even if we obtain some Dou Huang-level Heavenly Demon Puppets later, they probably won't be able to withstand the pill lightning, making them useless!"
"I choose you!"
Lin Feng waved his hand, and his storage ring flashed, revealing the corpse of Blood Sect Master Fan Lao in the secret chamber. Back when the Blood Sect was destroyed, Lin Feng had a flash of inspiration, thinking that although its level was low, it could still be used for experiments, so he stored it away.
Afterwards, Lin Feng took out a sixth-order water-attribute magic core and a large mass of processed sixth-order magical beast essence blood. Of course, the strange metals and, most importantly, the soul, were also included.
Actually, the secret method for refining the Heavenly Demon Puppet doesn't require the use of essence blood. However, Lin Feng was curious whether adding the essence blood of demonic beasts would enhance the Heavenly Demon Puppet's potential and initial strength.
"Boom!"
The Azure Lotus Earth Core Flame slowly rose from his palm, and with a wave of his hand, it instantly erupted, completely enveloping Fan Lao's corpse. With the support of Lin Feng's Dou Zong-level Dou Qi, the already intensely hot strange fire in the world unleashed unparalleled power. Visibly, Fan Lao's corpse showed signs of melting.
Seeing this, Lin Feng remained calm, as this was simply part of the Heavenly Demon Puppet refining process. As time passed, wisps of black energy drifted from Fan Lao's corpse, only to be instantly incinerated by the Azure Lotus Earth Core Flame.
Before long, the black energy representing Fan Lao's remaining will dissipated completely. However, Lin Feng did not stop. He continued burning for another hour before finally making a small hole in Fan Lao's head.
As for the location of the demon core in his chest, since Lin Feng had already spoken some heartfelt words to him, there was no need to do so now.
What appeared before Lin Feng was a Fan Lao whose body was completely drained of blood and had shrunk several sizes.
At this point, the true refining of the Heavenly Demon Puppet began. Lin Feng waved his hand, and a sixth-order water-attribute demon core floated to Fan Lao's chest. Then, he took out Fan Lao's soul from a jade bottle beside him. There was no unusual reaction. He was just a mere Dou Huang; how strong could his soul power be? After a brief glance, he stuffed it into his original mind.
Next came Lin Feng's innovative step: gradually lowering the temperature of the Azure Lotus Core Flame, just enough to prevent Fan Lao's flesh and blood from solidifying. Then, he controlled Fan Lao's mouth, opening it, and slowly let the essence blood of the sixth-tier magical beast flow into his body.
The dead body naturally lacked the ability to absorb and digest, so after all the essence blood was absorbed by Fan Lao, Lin Feng increased the temperature of the Azure Lotus Core Flame again, causing the magical beast's essence blood to slowly fuse with Fan Lao's body.
"Zzzzz..."
The flames intensified, and the flesh, soul, magical core, essence blood, and metal—these five elements were forced to seek a fusion opportunity under the powerful flames to prevent themselves from disappearing into the world.
Meanwhile, Lin Feng slowly closed his eyes and began refining the Dragon Emperor's essence blood within his body. After all, the refinement of the Heavenly Demon Puppet was no short process.
While the secret chamber where Lin Feng was located fell into silence, the outside was unusually lively.
Many elders who had received Lin Feng's pills couldn't contain their desire and quickly went into seclusion to consume them, attempting to advance further. Those who failed would take advantage of Lin Feng's presence to request the sect to grant them another pill on credit.
With so many high-quality pills available, quite a few elders successfully advanced. Of course, those who emerged from seclusion had all consumed Emperor-grade pills. After all, the energy required to break through to the Dou Zong realm couldn't be accumulated in a short time.
Naturally, for every success, there were failures. Because an Emperor-grade pill could only be consumed once in a lifetime, the few elders who failed were now completely wasted.
However, this had nothing to do with Lin Feng, as the quality of the pills he refined was undeniable.
Amidst this strange atmosphere of mixed joy and sorrow, ten days passed in the blink of an eye. At this time, within the secret chamber where Lin Feng was, an opportunity slowly emerged.
"Buzz!"
Lin Feng, who had been refining the Dragon Emperor's essence blood with his eyes closed, suddenly opened them. His hand seals changed rapidly, and then a strange syllable uttered from his mouth.
As this syllable was uttered, Fan Lao before Lin Feng seemed to receive a command, and suddenly his entire body began to emit a crystalline, dazzling light.
At this moment, the demonic core and soul within Fan Lao's body trembled violently, spontaneously forming a cycle. With each cycle, the energy around him gradually strengthened.
The crystalline, dazzling light, seemingly affected by the cycle, gradually dimmed, and finally, as if the power had been cut off, after a few flickers, turned pitch black. The aura emanating from his body was somewhat beyond Lin Feng's expectations, reaching the level of an eight-star Dou Huang, far surpassing Fan Lao's former strength.
"It seems that adding the essence of magical beasts can indeed fully stimulate the power of the demonic core and unleash its full potential!"
Of course, this was just an experiment for Lin Feng. According to the description in the Heavenly Demon Puppet Secret Technique, there are three grades of demonic puppets: Heaven, Earth, and Human, in gold, silver, and bronze. Although Lin Feng innovated the refining method of the Heavenly Demon Puppet, due to the limitations of Fan Lao's physical attributes, it only reached the level of an eight-star Dou Huang. Even if it received nourishment from Dan Lei or other strange energies later, it would not reach the level of Dou Zun.
In fact, it might only reach the strength of a seven- or eight-star Dou Zong at most, and any further improvement would cause it to crack. With Lin Feng's current level, he could roughly estimate the strength of a Heavenly Demon Puppet within the Dou Zong realm.
"It doesn't matter, this was originally just an experiment, and," Lin Feng smiled slyly, "before heading to Zhongzhou after returning to Canaan Academy, I can use this to extort another sum from that old fox Yao Chen!"
