Qi Zhiheng's initial guess was that something could inhibit the growth of the Netherworld Fungus, and it definitely couldn't be boy's urine...

To find out the specific reason for this, he himself has to investigate.

Following the direction where the demonic energy was thin, they discovered some traces of the other party's progress along the way.

Not long after, the divine soul imprint belonging to the other party disappeared again, and now there was nothing in front of him.

Qi Zhiheng did not doubt that he had come to the wrong place. After surveying the surroundings, he found some traces of formations!

Qi Zhiheng was extremely grateful that he had forced himself to learn some formations back then, otherwise he really wouldn't have been able to solve the formations that appeared here.

Unfortunately, his array formation skills were ultimately only rudimentary, and he couldn't even unravel the array in one go? Qi Zhiheng frowned slightly! Then he plunged into the array and buried himself in trying to solve it.

As soon as Bai Yilian entered the cave, she felt a chill seep into her bones, while her skin and muscles felt an unusual heat.

She was all too familiar with this feeling; during the days and nights she was locked in the alchemy furnace, she endured torment a hundred times worse than this.

From this feeling, she knew that what they were looking for was almost there.

The man in black robes was already instructing her: "After entering, do not resist its entry into your fire seed location. There is a wisp of its fire in your body, and it will become more unified and closer to you. As long as you can successfully come out of it, Qi Zhiheng, who is at the Mahayana stage, will never be your match in the future!"

Bai Yilian said in a cold tone, "I understand."

After walking a distance, the man in black stopped and said to Bai Yilian, "I won't follow you anymore. Remember what I said."

After the man in black finished speaking, he stood still.

Bai Yilian continued walking in as he instructed. The further she went, the darker it became, and the cold and scorching sensations intensified.

Bai Yilian's forehead began to sweat, and her body trembled uncontrollably. Her subconscious physical reaction was enough to prove that what was inside was terrifying.

I forced myself to walk to the end of the cave, where all I could see was darkness.

Then she saw it, her target this time: a ball of black flame.

She knew this flame was called Netherworld Fire, and it was absorbing a lot of demonic energy to strengthen itself.

Following the instructions of the man in black, she relaxed her body as much as possible and opened her arms to embrace the flame in front of her.

Qi Zhiheng spent several days before finally finding a clue to unravel the formation. But the necessary conditions for breaking the formation surprised him.

The activation of this formation actually requires demonic energy? He narrowed his eyes. It seemed that this place was indeed related to demonic energy. Perhaps the person Bai Yilian was connected to was a demonic cultivator.

Once we get inside, the whole truth will probably be revealed.

The most urgent task is to break the formation. Fortunately, it is not difficult for him to convert his spiritual energy into demonic energy. With the help of demonic energy, after spending some spiritual energy, he successfully broke the formation. Moreover, because of his demonic energy, the people inside were not alerted.

After breaking the formation, he entered another world, the most conspicuous thing in which was a cave. A cold, eerie aura emanated from the outside of the cave. Qi Zhiheng stepped inside.

Not long after, they unexpectedly encountered the man in black robes!

The man in black robes didn't even blink when he saw Qi Zhiheng.

Qi Zhiheng felt a little embarrassed. This person didn't even offer to fight him, and just stood there outside. What was he planning to do? This made him feel a little embarrassed to make a move.

The awkwardness was only momentary. Since the other party ignored him, he decided to go in and take a look.

From this vantage point, faint screams could already be heard emanating from inside the cave.

Qi Zhiheng guessed from the sound that the scream was Bai Yilian's.

Qi Zhiheng was walking in when the black-robed man, who hadn't even glanced at him before, blocked his way: "Since you're here, you'll have to live."

What happens here must not be spread outside.

Qi Zhiheng smiled and said, "I have a wife and children at home, and I don't want to lose my life. Please forgive me, senior."

As he was speaking, a surge of powerful and profound soul energy rushed over. Such strength must be the soul energy of someone in the Tribulation Transcending stage!

Qi Zhiheng was completely unafraid. The other party's soul was powerful? His soul was even more powerful! Since he woke up in this lifetime, no one had been able to compare with him in terms of the strength of their soul!

The two souls collided, and the black-robed man's soul was instantly shattered by Qi Zhiheng!

The man in black robes was immediately jolted! He was stunned for a moment!

Qi Zhiheng didn't hesitate and launched an attack directly! Although he was not as powerful as his opponent in terms of cultivation level, the depth of his spiritual power was something that the black-robed man could not match. After two moves, his opponent was already in a very bad state!

"Who are you!" The man in black robes hadn't expected to encounter such a powerful expert here, and immediately began to guess the other party's identity.

The number of Tribulation Transcending stage cultivators in Central Continent is limited. He had already gone through the names of several Tribulation Transcending stage cultivators in his mind, but for a moment, no one could match Qi Zhiheng!

The screams inside the cave grew increasingly shrill, and Qi Zhiheng only wanted a quick victory! He immediately stopped wasting words.

They launched an even fiercer attack.

Both the man in black robes and Qi Zhiheng had their cultivation suppressed, but it was clear that Qi Zhiheng, whose cultivation was suppressed, was superior. If his cultivation had not been suppressed, it would not have been easy for Qi Zhiheng to deal with a cultivator in the Tribulation Transcending stage. However, it was different with his cultivation suppressed. He also had a spiritual root, and the purity of his spiritual energy was refined, making him much better than an ordinary cultivator in the Tribulation Transcending stage.

He spent a little time defeating his opponent, and then used a piece of spiritual energy to imprison him outside! Since he was already half dead anyway, Qi Zhiheng felt at ease leaving him alone outside.

After dealing with the man in black robes, Qi Zhiheng continued walking inside.

At this moment, Qi Zhiheng also felt that hidden yet burning sensation! Qi Zhiheng searched his mind for relevant information, but couldn't think of what it was for a moment. In addition, Bai Yilai's screams were too loud, disturbing his thoughts.

So he simply stopped thinking about it and decided to go inside and find out the truth.

Finally, they reached the end of the tunnel, which was extremely dark inside. Qi Zhiheng lit a fire, but the light was completely suppressed by the darkness.

This made me very curious. What exactly is this thing?

Qi Zhiheng walked in and finally saw the other party's full appearance.

It was a magnificent cluster of black flames, enveloping a woman who was struggling and screaming in agony. Occasionally, parts of her body would be exposed, but she would soon be surrounded by the black flames again.

This woman was Bai Yilian.

Under the scorching heat, part of Bai Yilian's body gradually turned to ash, and as she turned to ash, the flames grew even stronger.

Qi Zhiheng guessed that Bai Yilian had the power to make the flames stronger.

Is Bai Yilian more like food?

Qi Zhiheng had no intention of going forward to save the person. He and Bai Yilian didn't have a friendly relationship, and Bai Yilian was looking at him with a hint of hatred. Naturally, he wouldn't rush to save the person.

Bai Yilian's eyes widened. When part of her body turned to ashes, she knew something was wrong. The sub-fire within her body not only failed to alleviate her pain but also resonated with her internal and external forces, making the burning even more thorough. At this point, it would be too foolish of her not to realize that she had been deceived!

The Netherfire slowly gnawed at her body, and she was like food offered up by the man in black robes, being consumed by the Netherfire!

Whether it's becoming powerful or seeking revenge, it all becomes an unrealistic dream.

Her initial idea was too idealistic! To become stronger and take revenge! If possible, she also wanted someone to be able to kill the man in black.

Unfortunately, she was nothing more than a tamed creature, food for the Netherfire. In the end, she could only turn to ashes in the cold and scorching flames. Before she died, she watched her enemy in front of her, as if he were watching a bizarre farce.

She hadn't even been able to take revenge, and was even watched by her enemy as she died—it was truly unbearable! That's what she thought before she died.

Qi Zhiheng watched all of this unfold with cold eyes, and by this time he already knew what was in front of him.

It is recorded in books that this is Netherworld Fire.

Bai Yilian had already been implanted with the Netherworld Seed. The energy contained in the Netherworld Seed was exactly what the Netherworld Fire needed to advance. This must be because someone was deliberately raising the Netherworld Fire!

The only thing Qi Zhiheng could think of was the black-robed man outside the door! This man was incredibly audacious, daring to raise anything. With his skill that couldn't even withstand a few moves from him, even if he wanted to subdue the Netherfire, he would only end up being burned to ashes.

Qi Zhiheng sneered, taking advantage of the fact that the fire hadn't yet remembered him, and began to think of a countermeasure.

He first used fire to completely envelop his body, thus eliminating the damage caused by the Netherfire.

Then he transformed all the spiritual energy around him into demonic energy with a slightly dark quality.

Sure enough, the moment his spiritual power changed, the damage from the Netherfire was greatly reduced.

The Netherfire naturally rejects spiritual energy and only accepts demonic energy. It approached Qi Zhiheng step by step, but was somewhat wary of the flame on Qi Zhiheng's body.

The fire seed on Qi Zhiheng's body was now a semi-transparent white, a result of his years of using the essence of fire fruit to advance his fire seed.

Even if his own flame were to fight against the Netherworld Flame, it would not be inferior!

Qi Zhiheng unleashed his own fire, illuminating half of the originally dark cave with a vast expanse of flame! The two flames, one black and one white, each occupied half the territory, displaying a fierce and confrontational stance!

Qi Zhiheng attacked Confucius's own name, Ou Zhong. The two flames first collided in a confrontational manner, and then the white flames suddenly surged! Enveloping the entire black flames within them, instantly transforming into the shape of a giant glutinous rice ball.
