Within the Ten Thousand Poison Mountains, the Poison Emperor personally led Lin Feng and the others to the Cultivation Technique Pavilion and the Spiritual Item Chamber, where they selected numerous spiritual items.
At Lin Feng's behest, Little Fairy Doctor also collected all the spiritual items usable by experts above the Dou Ling level. Combined with the many core secret techniques of the Ten Thousand Poison Cave, Lin Feng paid the price of four Royal-grade Pills and eight Dou Ling Pills.
This resulted in Lin Feng not having enough pills left to pay, forcing him to stay in the Ten Thousand Poison Mountains for several more days. During this time, the people of the Ten Thousand Poison Cave were extremely generous, allowing Zi Yan and Little Fairy Doctor to search for treasures within the Ten Thousand Poison Mountains. As long as they didn't cause malicious damage, they could keep everything they found.
Hearing this news, Zi Yan was overjoyed. In the Chu Yun Empire, where poisonous gas permeated everywhere, she had long been somewhat impatient.
After that, Zi Yan's behavior immediately made the people of the Ten Thousand Poisons Cave turn green with embarrassment. If Little Fairy Doctor hadn't stopped her from taking too much, the Ten Thousand Poisons Cave would have suffered a huge loss.
Of course, when Lin Feng emerged from seclusion and handed over the Dou Ling Pills and Dou Huang Pills to the Poison Emperor, many elders were overjoyed. With this batch of pills, the Ten Thousand Poisons Cave would definitely be able to leave the Ten Thousand Poisons Mountain Range and obtain more spiritual items.
Indeed, although the Ten Thousand Poisons Cave was powerful before, due to the suppression of the royal family, its headquarters could only remain within this mountain range.
Of course, all of this was no longer relevant to Lin Feng and the others. Under the reluctant gazes of the Poison Emperor and the others, Lin Feng and the others boarded the back of Xuan Wu and began their return journey.
High in the sky, Lin Feng and Zi Yan were chatting casually, while Little Fairy Doctor was in her room, organizing the many secret techniques she had obtained from the Ten Thousand Poisons Cave.
"Hmm!? What's this fluctuation?"
Suddenly, Lin Feng, who was chatting with Zi Yan, frowned, as if sensing something. He commanded Xuan Wu to stop high in the sky, its huge wings slowly flapping.
"Lin Feng, what's going on? Is someone attacking us? This young lady's fists will definitely teach them a lesson!"
Seeing Lin Feng suddenly stop Xuan Wu, Zi Yan, who was standing to the side, was eager to try. Since advancing to the Dou Huang realm, she had never fought, and her fists were itching to fight.
"Brother Lin Feng, did you feel that fluctuation?"
Before Lin Feng could answer, Little Fairy Doctor slowly walked out of the room, her expression somewhat strange.
"Lin Feng, Little Fairy Doctor, what exactly did you sense? Why didn't my talent show any response?"
"If I'm not mistaken, this is a strange fire. And since Fairy Doctor also sensed it, this strange fire might be the 'Netherworld Poison Fire,' ranked twentieth on the Strange Fire Ranking!"
"Netherworld Poison Fire!?"
Hearing Lin Feng's words, Little Fairy Doctor was shocked. After many days of study at Canaan Academy, she was no longer an ignorant little doctor. Strange fires, these rare treasures of heaven and earth, even her brother Lin Feng had only encountered one by chance.
"That's right, it's the Netherworld Poison Fire. With this strange fire, perhaps Fairy Doctor's Calamity Poison Body can be completely resolved, without needing to seal and limit its potential."
Lin Feng's expression was somewhat excited. This Calamity Poison Body could be said to have unlimited potential, and this strange fire of heaven and earth could also be said to have unlimited potential. The combination of these two was even more useful than the Poison Pill method.
After all, the magic core used in that poison pill was only of the seventh rank. Even if it were an eighth-rank Venerable-level magical beast, it would still be nothing but an inanimate object. How could it compare to that infinitely potential strange fire?
"What does Brother Lin Feng mean?"
Seeing that Little Fairy Doctor and Zi Yan were somewhat puzzled, Lin Feng immediately shared his guess, and the two of them became very excited.
"Even if this Netherworld Poison Fire cannot completely resolve the problem of the Calamity Poison Body, it can still rapidly increase Xian'er's cultivation speed. Moreover, in terms of combat power, it can surpass her previous level by a large margin."
After the three of them had discussed it, Lin Feng quickly controlled Xuanwu to head towards the sensing area below.
"Howl!"
As Xuanwu drew closer, it suddenly roared, as if something ahead terrified it.
"Brother Lin Feng, Sister Ziyan, these are antidotes I refined. They primarily contain the essence of poison, using poison to counteract poison. Even poison from a Dou Huang expert can be neutralized."
After giving the two the antidotes, Little Fairy Doctor flicked her finger, sending another antidote into Xuanwu's mouth. Sure enough, after the pill entered its body, Xuanwu continued its journey down the mountain.
When the massive Xuanwu landed, the ground was already shrouded in a dense gray aura. Even with Lin Feng's powerful soul force, his perception was reduced by half.
"Fairy, Ziyan, be careful. In my sense, this strange fire, while not as powerful as the Azure Lotus Earth Core Fire, still possesses the cultivation of an early Dou Huang."
After carefully sensing the aura, Lin Feng immediately recognized the strange flame hidden behind the gray aura.
"Xian'er, you and Xuanwu will hide in the back. Ziyan and I will act quickly to try and seal it. After you reach the Dou Huang or Dou Wang high-level, I will assist you in refining it."
Without much hesitation, Lin Feng decided on the battle plan.
"Okay!"
"Tap tap tap,"
Lin Feng slowly made his way through the gray mountains. Reaching a certain point, he gestured for Xiao Yixian to stop.
"Ziyan, get ready!"
Without Lin Feng saying anything, Ziyan and Xiao Yixian saw a burning stream of energy ahead, their breaths tightening. Although they hadn't witnessed how Lin Feng subdued the Azure Lotus Earth Core Flame, since it was a rare treasure, it must have something special.
A careless move could lead to disaster.
As Lin Feng and Ziyan approached, the gray energy suddenly burst into flames, as if sensing something.
"Damn it! The poisonous gas in this mountain range all originates from the Netherworld Poisonous Fire. Even with my soul power concealing it, it's impossible to avoid being detected if we get too close."
"Zi Yan, quickly, follow me!"
Realizing the Netherworld Poisonous Fire had discovered their presence, Lin Feng didn't hesitate any longer, his battle qi surging instantly.
"Five Elements Sealing Technique!"
"Dragon Seal!"
Two loud shouts instantly rang out from the left and right of the Netherworld Poisonous Fire, and the surrounding gray air currents, under its control, completely boiled over.
The entire mountain range seemed to be completely ignited by the Netherworld Poisonous Fire's outburst.
