The hardest step?
Cai Lin on the side heard what Yao Lao said and couldn't help but ask, "What's the most difficult step? Wasn't the process of him refining the strange fire very smooth?"

Yao Yan's aura was constantly increasing at this moment, but she didn't seem to be having any difficulty at all. The Fallen Heart Flame that she had swallowed into her stomach was suppressed and unable to move, allowing her to refine it at will. She really couldn't see what was difficult about it.

"…Ordinary people can only contain one kind of strange fire at most. He uses the power of his technique to contain two kinds of strange fire at the same time. This may indeed cause some sequelae."

Venerable Tianhuo pondered for a moment, and suddenly seemed to have thought of something. A strange look flashed in his eyes, and he muttered something. At the same time, he glanced at the serious Yao Lao. The eyes of the two old guys suddenly intertwined, and then they coughed at each other. It was obvious that they had guessed similar things.

As an alchemist who possesses the cold fire of bone spirit, Yao Lao naturally understands the peculiarities of strange fire. If the human body wants to perfectly integrate it, it will inevitably be affected by it, especially the strange fire like the Fallen Heart Flame which has a great influence on the mind. The evil fire it brings is definitely stronger than the Green Lotus Earth Core Fire. Especially for a young man like Yao Yan who is full of blood and vigor, the yang energy in his body will inevitably soar after a little stimulation.

If it is not channeled, it is very likely to go astray.

As for how to channel...

Yao Lao looked a little embarrassed, but he didn't say it directly. Instead, he glanced at Cai Lin. With his many years of experience, how could he not see that Queen Medusa was somewhat interested in Yao Yan, otherwise she wouldn't be so concerned about this boy. However, perhaps because of her sister Cai Die, she had been restraining her feelings and deliberately keeping a distance from Yao Yan.

But this membrane needs to be broken eventually.

As an experienced person, he naturally doesn't want to see Cai Lin regret it in the future. This is also an opportunity. If he grasps it well... it will be a good opportunity for Yao Yan, the brat.

"What on earth are you talking about?"

Cai Lin's eyes were filled with more doubt. She looked at the two frivolous old guys in front of her and asked with a frown.

Venerable Tianhuo coughed and gave Yao Lao a look, asking him to explain something.

Yao Lao, the old man, was obviously not a serious person. Looking at the ignorant Queen Medusa, he showed his thick-skinned basic skills. His face was slightly serious and he said in a deep voice, "He can't stand being disturbed during his retreat. In the process of refining, the Yang Fire in his body will continue to surge. He can't stand stimulation. I have the Bone Spirit Cold Fire in my body, so it's not appropriate for me to protect him. He was the former owner of the Fallen Heart Flame, so it's easy for him to cause some accidents. So, I'll have to trouble you for the next period of time."

He spoke very seriously, and his arguments were well-reasoned. Even the Skyfire Venerable who was standing beside him couldn't help but look at him, as if he had gotten to know this old guy all over again.

"I see."

Cai Lin nodded. She didn't think this was a difficult task. She also wanted to use this time to familiarize herself with the aura of the strange fire and prepare for her future evolution. By observing Yao Yan, she could also gain a lot of experience.

Yao Lao and Tianhuo Zun looked at each other, and the two old guys turned away their gazes with a guilty conscience, and then walked out of the secret room one after another. Before leaving, they did not forget to seal the door. As for what would happen next, the two of them had a rough idea in their minds. At their level, many things could be easily deduced.

"Isn't it a bit immoral for us to do this..." Venerable Tianhuo hesitated and asked Yao Lao.

"Then Queen Medusa is deeply in love with this boy, but she doesn't realize it. If I don't help her, I guess she will never get married in her lifetime. I am also the elder of this boy, and I don't want to see him miss a good marriage. I will help him as much as I can."

Different from Venerable Tianhuo's moral bottom line, the old man Yao Lao obviously has a flexible bottom line, and his words are even more confident, which made Venerable Tianhuo stunned. However, there is one thing that Venerable Tianhuo can be sure of, that Queen Medusa does care about Yao Yan very much, and perhaps she really has deep feelings for him... After all, he has only been in contact with them for a short time, so some things should not be said too much.

Think of this.

Skyfire Venerable suddenly said: "That kid's soul realm has reached the spiritual realm. In theory, he should be able to withstand the backlash of the evil fire and remain calm."

"If we were in there, he would probably fight to the death... That's why I pulled you out." Yao Lao chuckled, then paused and said in a slower tone: "It's better to release than to block. We can't hold back our anger forever. Instead of letting him harm other women, it's better to find someone who shares the same ideals with him."

Upon hearing this, Venerable Tianhuo didn't know what to say. He nodded, then followed the other party out of the secret room. As for how the other party dealt with the evil disciple Han Feng, he was not curious. After all, he was not very familiar with Yao Lao, and as a newcomer, it was obviously better to keep a distance.

Instead, Yao Lao was full of curiosity about Venerable Tianhuo. Perhaps it was because he had untied the knot in his heart, and his mentality seemed to have returned to what it was before.

……

Cai Lin, Queen Medusa, was obviously unaware of what the two old guys were whispering about. She was staring at Yao Yan intently at this moment, sensing the changes in his body and trying to feel the power of the strange fire. Perhaps because she was too close to Yao Yan, the Fallen Heart Flame in his body actually produced the power of the original heart fire in her body. A burning breath instantly surged through her body, making her pretty face turn a little redder.

Fortunately, his strength is quite good, and the fighting spirit he cultivated is also of fire attribute. With the assistance of his companion soul, the Purple Nether Flame Snake, he can make perfect use of it.

The original heart fire that seemed extremely terrifying to outsiders not only did not cause any harm to her, but also tempered her fighting spirit and body.

"This power... is it the power of the Fallen Heart Flame's heart fire?"

Cai Lin blinked her beautiful eyes, showing a hint of strangeness. She then looked at Yao Yan and hesitated for a moment. Then she twisted her waist and moved closer to Yao Yan. Then she coiled her enchanting purple snake tail and began to practice beside Yao Yan.

Yao Yan did not pay too much attention to what was happening in the outside world. His mind was completely immersed in his body at the moment, feeling the fusion of the two flames. The process of the fusion of the origins of the strange fire was extremely strange, as if it contained some mysterious rules. If he could fully understand it, perhaps he could figure out the true meaning of the Burning Decree.

However, with Yao Yan's current level of cultivation, it is obviously impossible for him to understand these things. The most he can do is to use this to improve his understanding and control over the strange fire.

Time passes slowly, and the years seem to have lost their meaning.

In a quiet secret room.

The two figures continued to sit facing each other, with faint white flames lingering around them. They kept appearing and disappearing, making the aura of the two people stronger. It was unknown how long it had been, until the white flames on Yao Yan's body were replaced by emerald green flames. Then Cai Ling, who was sitting opposite him, opened her eyes instantly. A look of surprise appeared on her beautiful and cold face, and she stared at the emerald green flames that appeared on Yao Yan's body.

The aura emitted by the flame was extremely terrifying. Just staring at it gave one a sense of extreme danger.

Its degree of danger has undoubtedly exceeded the original Fallen Heart Flame.

"Is it done?" Cai Lin looked at all this and said secretly in his heart.

At this moment, Yao Yan slowly opened his eyes. The two kinds of strange fire that were originally blending in the cyclone position in his body had been completely replaced by a ball of emerald green flame. Thanks to the power of the Fallen Heart Flame, the slight aura of the seventh-level beast fire that was originally contaminated had also completely disappeared.

His dark eyes were covered with emerald green flames and an extremely powerful fighting spirit instantly emerged from his body, flowing through his limbs and bones. The warm feeling made his aura soar in an instant, and he suddenly broke through from the nine-star Dou Wang level to the Dou Huang level. He did not stop there, and the one-star Dou Huang level broke into the two-star Dou Huang in an instant, and then stepped into the three-star, and did not slow down until he reached the four-star Dou Huang level.

The speed at which his strength increased stunned Cai Lin who was standing by. She couldn't help but purse her red lips, and a look of surprise rose in her eyes.

She knew that the bottleneck of Douhuang could not stop Yao Yan, but the speed at which the other party's strength was improving was a little too exaggerated.

"Four-star Douhuang, not bad~"

Yao Yan smiled, then restrained his breath, and took the emerald green flames that erupted from his body into the 'Na Ling'. Then he was ready to tease the Queen Medusa in front of him. However, the moment he poured the fused strange fire into the 'Na Ling', it suddenly trembled, and then he felt his heart suddenly being gripped, and an indescribable evil fire force rose from his lower abdomen, and instantly flowed through his body, making his body turn red in an instant.

Damn it, I almost forgot... The smile on Yao Yan's face suddenly froze. He was a little too proud of himself and even forgot the biggest problem of swallowing the strange fire.

This kind of reaction had occurred in his body when he was refining the Azure Lotus Earth Core Fire, but the reaction back then was not as terrifying as after the fusion of the two strange fires. At least he was able to remain calm at the time, but now, he felt that he could no longer hold it in, especially when Cai Lin was so close to him.

Perhaps only those who have seen Queen Medusa with their own eyes can feel how beautiful and enchanting she is. Her delicate skin, graceful and proud figure, and cold and charming face all arouse men's nerves.

"..."

Yao Yan closed his eyes, took a deep breath, and tried to force himself on her. He couldn't do such a shameless thing as forcing himself on her. Besides, Cai Lin was Cai Die's sister. Even if he wanted to do it, he had to do it openly.

Cai Lin also came back to her senses at this moment. Seeing Yao Yan's breath suddenly becoming disordered, she couldn't help but twist her waist and move closer, with some concern and confusion in her eyes: "What's wrong? Wasn't he fine just now? How did he suddenly become like this?!"

The charming and soft voice, even if it was not intentional, was like a teasing little hand, teasing Yao Yan's fragile nerves.

The faint fragrance in the air increases the stimulation.

At this moment Yao Yan also reacted. Why was Cai Lin the only one left in the secret room? Where did the two old guys Yao Lao and Tianhuo Zunzhe go? He didn't believe that these two old guys didn't know the sequelae of the fusion of the strange fire. They actually left Cai Lin alone in the secret room, staying in the same room with him, a man and a woman, as if they were afraid that he wouldn't get enough stimulation.

Two old immortals... Yao Yan didn't know whether to praise them or scold them for a moment, but there was one thing he was sure of, that was that Cai Lin had really stimulated him greatly. The abnormal evil fire in his body increased several times in an instant. At this moment, when he opened his eyes, the whites of his eyes were bloodshot.

"Are you... okay? I'll go find them, just bear with it!" Cai Lin knew at this moment that Yao Yan's condition was very bad, and she immediately wanted to find Yao Lao and others for help.

"No, they can't help me." Yao Yan reached out and grabbed Cai Lin's slender arm. His breathing became heavier, but fortunately his eyes were still somewhat clear. Looking at Cai Lin's charming and beautiful face, he slowly said, "You are the only one who can help me now."

Cai Lin was stunned when she heard this, and her beautiful eyebrows slightly frowned: "Tell me, how can I help?"

"I didn't expect that the compatibility of the two strange fires would produce such a big reaction. The evil fire energy generated has already attacked my heart. If I don't vent it out, I will most likely go astray..." Yao Yan clenched his fists and said with some difficulty.

"you……"

Cai Lin hadn't reacted yet. She was not an ignorant person, so how could she not understand the meaning of Yao Yan's words? Her eyes suddenly turned cold, "Don't even think about it. Don't forget, I am Cai Die's sister!"

She might not even know how much her words stimulated Yao Yan. The queen-like attitude she revealed at this moment aroused Yao Yan's deepest desire, which came from the male instinct of conquest.

"But I can't hold it anymore."

Yao Yan said with a flushed face, the clarity in his eyes was almost covered by desire.

"Just bear with it, I'll take you out to find a woman!" Cai Lin's pretty face turned slightly red, she gritted her teeth and said.

"I'm not that casual."

Hearing this, Yao Yan immediately let go of Cai Lin and sat cross-legged with great courage, as if he wanted to suppress the evil fire energy with his willpower. However, this kind of oppression had the opposite effect, and white mist began to appear on his body.

"Then why did you accept my gift back then!" Cai Lin questioned immediately after hearing that. When Yao Yan accepted Hua She'er and the others, he was not so noble.

"They are different. I thought they were the dowry of Caidie."

Yao Yan said confidently that he could still hold back at the moment, but he also wanted to see what Cai Lin thought of him, whether she would really watch him being burned by the evil fire and choose to stand by and watch.

"you……"

Cai Lin was furious and glared at Yao Yan. The person was about to die, so why was he still sticking to his principles? Yao Yan seemed quite flexible in the past, but why did he suddenly have a so-called bottom line when it came to these things? Could it be that he really wanted her to serve him? That was wishful thinking on his part.

"Do you think this king will care about your life or death?!"

She stared at Yao Yan with cold and arrogant eyes and snorted.

Yao Yan cooperated and spat out a mouthful of blood. His breath became more and more disordered and his whole body temperature was frighteningly high, as if he would explode at any time. It seemed that if Cai Lin didn't give him the blood, he would really die in front of Cai Lin.
