Douluo Continent: I, Long Aotian, will not be a supporting character.

Long Aotian had already planned for the future. As for the various opportunities in the original work, he naturally wanted to seize them first by relying on his foresight. After all, cultivation is going against the heavens, and the so-called opportunities are only real if they are in one's own hands.

This time, taking advantage of the need to treat Du Bisi, we can obtain the immortal herbs from the Yin-Yang Well of Ice and Fire to strengthen ourselves and our sect.

"Master, perhaps I know where there are miraculous herbs that can cure you."

"Aotian, how did you know? Where are the divine herbs? Tell me quickly."

Upon hearing Long Aotian's words, Du Busi became so excited that he grabbed Long Aotian's small shoulders with both hands and shook him incessantly.

"Master, don't rush, let me explain it to you slowly."

"Master, do you know the ancestor of Shrek Academy, the key figure of the first generation of Shrek Seven Devils, the Sea God Tang San?"

"Master, of course I know. Those hypocrites from Shrek Academy keep proclaiming that their ancestor is the Sea God Tang San. Who on the entire continent doesn't know that? But what does this celestial herb have to do with the Sea God Tang San?"

"Master, I've deduced this from reading many ancient texts. It's said that when Tang San, the Sea God, was young, he obtained an incredible opportunity—in the Sunset Forest, he encountered a treasure trove formed by heaven and earth—the Ice and Fire Yin-Yang Well. Within the Ice and Fire Yin-Yang Well, many celestial herbs grow. The first generation of the Shrek Seven Devils, including Tang San, all consumed these celestial herbs from the Ice and Fire Yin-Yang Well. There's also evidence to support this: the Nine Treasure Glazed Tile School, despite being called the Seven Treasure Glazed Tile Pagoda, is named so because its ancestor, Ning Rongrong, evolved her Seven Treasure Glazed Tile Pagoda into the Nine Treasure Glazed Tile Pagoda using celestial herbs. Therefore, the Seven Treasure Glazed Tile School was renamed the Nine Treasure Glazed Tile School. Combining these ancient texts and rumors, I think it's true that there are celestial herbs within the Ice and Fire Yin-Yang Well. Perhaps the celestial herbs that you need, Master, are hidden within it."

Long Aotian possessed precognitive abilities due to his reincarnation, but such matters could not be openly discussed. Therefore, he sought out ancient texts and legends as pretexts to persuade Du Busi.

After listening, Du Busi pondered for a moment and then said, "Aotian, your speculation makes some sense. Regardless of whether the rumor is true or false, I must try to find it for my brother's sake."

"In that case, although Sunset Forest is not small, it is far smaller than Star Dou Great Forest. Moreover, there are not many strong soul beasts interfering in Sunset Forest, so we can definitely search it out."

"Brother, it won't be long before I can wake you up. Just wait for me!"

After saying that, Du Busi took Long Aotian away from the ice cave. He told the gatekeeper that "the sect leader has gone out on business," then picked up Long Aotian and flew away, leaving the Body Sect and heading towards the Sunset Forest.

The level 98 Super Douluo flew at full speed, and in a short time, he flew from the northern region of the Heavenly Soul Empire to the heartland of the Heavenly Soul Empire, to the location of the Heavenly Soul Imperial City.

Ten thousand years ago, the Heavenly Soul Imperial City was called the Heavenly Battle Imperial City, and the Sunset Forest was located a hundred miles east of the Imperial City.

Ten thousand years ago, Sunset Forest was one of the three major gathering places of soul beasts on the continent, along with the Frozen Forest in the far north and the Star Dou Great Forest. However, over the years, the number of soul beasts in Sunset Forest has decreased for some unknown reason, and fewer and fewer soul masters have come here to hunt for soul rings. Sunset Forest has gradually become a desolate forest that no one sets foot in.

Long Aotian, who was familiar with the original work, knew that the reason why Sunset Forest was completely desolate was because Tang San had placed countless poisonous plants, the Seven-Colored Jade Phosphorus Flowers, in the Ice and Fire Yin-Yang Well. Together with the surrounding poisonous miasma, they formed a protective barrier for the Ice and Fire Yin-Yang Well. Over the past ten thousand years, the area covered by the Seven-Colored Jade Phosphorus Flowers and the poisonous miasma has increased, covering nearly half of Sunset Forest. Its toxicity is so strong that even ordinary poison-attribute soul beasts cannot withstand it. Tang San did this to prevent soul beasts or soul masters from entering the Ice and Fire Yin-Yang Well.

As the Seven Absolute Flowers of Azure Phosphorus and the poisonous miasma gradually spread, the soul beasts in Sunset Forest were either poisoned to death or fled Sunset Forest. The number of soul beasts decreased, and soul masters no longer came here to hunt for soul rings. Tang San's goal of sealing off the Ice and Fire Yin-Yang Eye was achieved.

Poison Immortal carried Long Aotian and flew to the sky above Sunset Forest. Looking down at the desolate and lifeless Sunset Forest, Poison Immortal asked, "Aotian, are you sure the Ice and Fire Yin-Yang Well is inside Sunset Forest? It looks lifeless; it doesn't seem like a place that can nurture immortal herbs."

"Master, according to the ancient texts, it is right here."

Poison Immortal waved his hand and said, "Alright, in that case, let's land here and walk into the forest to explore carefully."

After saying that, Du Busi flew downwards, put Long Aotian down, but still held onto Long Aotian and walked into the forest.

After traveling for a short while, they saw a thick layer of poisonous miasma ahead.

The poisonous miasma covers a vast area, encompassing most of Sunset Forest. It cannot be bypassed from any direction; only by breaking through the miasma can one enter the forest.

The poisonous miasma is extremely complex, a mixture of plant toxins, animal toxins, and the toxic gases from the decaying corpses of dead soul beasts. Over tens of thousands of years, it has evolved into a mixture of various toxins, making it impossible to detoxify.

However, Poison Undying is a perfect match for the poisonous miasma. The innate poison contained in his martial soul is already the most potent poison in the world. With the strength of a level 98 Super Douluo, he can push his innate poison to a level comparable to the ultimate poison. This poisonous miasma accumulated over ten thousand years is not a problem for him, but rather a tonic for him.

"I never expected that Sunset Forest would contain such a large area of ​​extremely poisonous miasma. It's quite an unexpected surprise for me."

"Aotian, I'm going to try absorbing the poisonous miasma, not only to enter the forest, but also to temper my poisonous soul core. You must be careful not to get close to the miasma. Let alone touch it, even inhaling a trace of it would be too much for you to handle in your current state."

"Yes, Master, I understand. I won't get too close."

"Alright! I'm about to begin, so be careful."

After saying that, Du Busi walked directly into the poisonous miasma and sat down cross-legged.

As Du Busi circulated his soul power, the poisonous miasma suddenly surged violently around him. Then, like a funnel, it was sucked into Du Busi's body. Gradually, the miasma surged more and more violently, eventually forming a miasma tornado.

An hour passed, and although the tornado storm had thinned considerably, it still existed. The poisonous miasma in this area had been completely absorbed by Poison Undying, but the poisonous miasma in other areas of Sunset Forest was still being continuously absorbed by Poison Undying.

Two hours passed, and the tornado gradually subsided, revealing the surviving poisonous miasma.
