Douluo Continent: I am a biologist, and I have awakened a weapon spirit?

Chen Feng pondered for a moment, then asked Dugu Bo:

"Senior, do you still remember the predicament you faced back then?"

"Of course I remember," Dugu Bo said in a deep voice, still vividly remembering the torment he suffered from the toxins in his body.

Chen Feng smiled slightly and said:

"The reason you were harmed by the toxins in your body back then was mainly because the toxins were very potent and exceeded your tolerance. Now that the Heavenly Ice Lotus has solved this problem, don't you want to pursue a higher level in the art of poison?"

Dugu Bo had a vague understanding of it, but still felt it wasn't quite clear, so he asked:

How to pursue it?

Chen Feng pointed at Tang San and said:

"Xiao San just said that he has a way to turn several non-toxic medicinal herbs into a terrifying mixed poison, and I believe that this method is the key for you, Poison Douluo, to pursue a higher level of poison."

Dugu Bo frowned. "The poison I use is a single entity; how can I use such a method?"

Chen Feng smiled and reminded him, "Senior, Xiang Liu has more than one head."

Dugu Bo's eyes widened instantly, as if he had been struck by a sudden enlightenment.

Chen Feng continued:

"Although Xiao San possesses such methods, she may not understand their fundamental principles. If you and Xiao San were to grasp the underlying principles of these methods, given Xiang Liu's nine-headed talent, the resulting mixed toxins would likely..."

He didn't continue speaking, but Dugu Bo already understood what he meant.

“That’s right. Toxins don’t become more potent simply by mixing them. There’s some kind of inherent law involved. If I could understand this, I could make Xiang Liu’s nine heads—no, not even nine heads, just a few heads—produce many kinds of terrifying toxins.” As he said this, Dugu Bo suddenly shivered involuntarily.

If this really happens, what kind of scene will it be when he appears with nine heads?

Dugu Bo recalled Chen Feng's description of Xiang Liu, which was simply a walking disaster. It was not an exaggeration to say that nothing would grow in the places it went, but a realistic depiction.

In other words, if he truly cultivates his Xiangliu Martial Soul to its full potential, he will become a true calamity, capable of slaughtering cities and destroying countries without a second thought, and will pose a real threat to enemies at the level of Title Douluo.

Of course, Dugu Bo had no interest in massacring cities and destroying countries, but he felt that although he could choose not to use such methods, he could not be without them.

Moreover, being constantly told that he was the weakest Title Douluo naturally made Dugu Bo very unhappy. In the past, it was because of his innate deficiency that he had no choice but to try. But now that he had a way, he had to take a gamble.

Thinking of this, Dugu Bo said to Tang San:

"Just do as Mr. Chenfeng said. You can use any of the herbs here. My only requirement is that I must watch you make that mixed toxin the whole time."

"No problem," Tang San nodded without hesitation.

"It's best to explain the properties and uses of herbs to your seniors before using them," Chen Feng added.

"That's only right." Tang San nodded and said, "If you need me to, senior, I can explain all the herbs I know about this place, so that it will be convenient for you to use them in the future."

He was indeed very grateful for Dugu Bo's help; not just anyone could easily lend out such a precious place as the Ice and Fire Yin-Yang Eye.

Tang San's mother did not die completely, but left behind a seed. According to his father, his mother's soul was hidden in this seed. As long as the seed grows to a certain extent, his mother will be able to regain consciousness.

By then, their family will be reunited.

If this were happening outside, there would be virtually no hope for such a thing.

However, with the Ice and Fire Yin-Yang Well, Tang San's mother was able to grow back at an extremely fast speed, and regaining consciousness was no longer an unattainable dream.

Therefore, Tang San was extremely grateful to Dugu Bo for lending him the Ice and Fire Yin-Yang Well, and was even willing to share all his knowledge of herbal medicine, including his understanding of immortal herbs, with Dugu Bo.

"Are you going to give me a lecture?" Dugu Bo smiled. "Sure, there are a lot of herbs in this place that I don't really recognize. It would be good if you could explain them to me."

Chen Feng's gaze fell on an inconspicuous herb. The herb was entirely green, but strangely, there were three snow-white leaves in the center of the herb, with a few water droplets in the center of the leaves, like dew left in the morning.

If he remembered correctly, this herb should be the long-awaited dew.

In the original novel, with the help of the "Looking Through Autumn Water Dew," Tang San raised his Purple Demon Eye to the Mustard Seed Realm, which allowed him to see through Xiao Wu's true form.

Chen Feng wanted to see if Tang San could discern the special properties of the Thunder Essence Stone after using the Autumn Water Dew.

He was still quite concerned about the external soul bone he had inexplicably obtained. If he could figure out the underlying principles, then creating soul bones might not be impossible.

As for why Chen Feng didn't use the "Looking Through Autumn Water Dew" himself, it was mainly because his Purple Demon Eye was inferior to Tang San's. To be on the safe side, it was better to let Tang San use it.

Anyway, the "Wang Chuan Qiu Shui Lu" mainly uses dew, and you don't need to eat the whole herb.

If you just absorb the dew and use it, the recovery should be faster, right?

If this idea succeeds, then the advancement of Chenfeng's Purple Demon Eye will only be a little later, and it won't delay anything.

Chen Feng's blank stare at a certain herb caught Tang San's attention. Following Chen Feng's gaze, Tang San began to explain:

"This herb is called 'Wang Chuan Qiu Shui Lu' (望穿秋水露), and using the dew from it is very beneficial for eye health."

After hearing about the effect, Dugu Bo waved his hand and said:

“I have never trained my eyes. If you want it, Mr. Chenfeng, you may use it.”

He saw Chen Feng's eager look, so he generously gave him the herb that was of little use to him.

"I don't intend to use it myself," Chen Feng shook his head and said to Tang San.

I wanted you to use it.

Chapter 139 Mysterious Patterns

"For me to use?"

Tang San was taken aback and asked:

"Xiao Feng, aren't you going to use it yourself?"

Chen Feng shook his head. "You've been practicing the Purple Demon Eye for a longer time, so you should start using it first. I don't need to rush."

For him, the Purple Demon Eye is now sufficient, enabling him to see the enemy's movements clearly in battle and allowing him to counter their moves using Tai Chi swordsmanship.

It wasn't that Chen Feng didn't want to improve his Purple Demon Eye technique; it was mainly because he started practicing it a few years later than Tang San and didn't practice as diligently as Tang San.

Therefore, he worried that the "Looking Through Autumn Water Dew" would not be enough to help him, and that raising the Purple Demon Eye to the Mustard Seed Realm would be a waste of a good thing and would also delay his research on the Thunder Essence Stone.

After Tang San uses the Autumn Water Dew, his Purple Demon Eye will most likely be able to advance to the next level. This is the confidence that both the original novel and the comics give Chen Feng.

Tang San didn't quite understand Chen Feng's plan, but he was touched by his friend's humility.

So he nodded, "Okay, I'll use it first, and I'll find a way to help you get more later."

Chen Feng waved his hand, "Actually, it may not take too long. Xiao San, are you going to pluck the whole thing off to use the Longing for Autumn Dew?"

"Yes."

"What if we don't pick it off?"

Tang San paused, looking thoughtfully at Wang Chuan Qiu Shui Lu, "You mean, we can use it directly like this without damaging it?"

"Will it work?" Chen Feng asked.

"Uh... I don't know either," Tang San said, somewhat bewildered.

According to the records of the Tang Clan, these herbs should be picked before use. Generally speaking, these herbs grow in places that are not good places, either guarded by powerful creatures, or not suitable for people to stay for long. Therefore, picking them is the default practice.

However, since Chen Feng has said so, there's no harm in giving it a try.

Thinking of this, Tang San walked to the side of the "Looking Through Autumn Water Dew" herb, and after a moment's thought, he lay down next to the herb and moved his head under the dew.

Then he said:

"Xiao Feng, come help me, so it doesn't spill and go to waste."

Seeing Tang San's actions, Chen Feng couldn't help but ask:

"Why not just use a container to extract the dew from these herbs and then use it? Is it really okay to just lie there like that?"

"Xiao Feng, you don't know this, but when using this herb, you have to drink the dew directly. I don't know what would happen if I used a container to collect it, or if it would make the dew lose its effectiveness. We don't have the resources to do such an experiment, so it's safer to use it directly like this," Tang San replied, lying on the ground.

"Your thinking is rigorous." Chen Feng gave him a thumbs up and then walked over.

Dugu Bo, who was listening in, nodded slightly and wrote down what the two boys said.

If Chen Feng's idea is feasible, then these herbs can be reused repeatedly. Although Dugu Bo himself hasn't trained his eyesight much, and neither has Dugu Yan, Dugu Yan will definitely have successors in the future, and then their experience in this area will come in handy.

Chen Feng arrived at the side of the "Looking Through Autumn Water Dew" and, after Tang San opened his mouth, dripped a few drops of the transparent liquid from the "Looking Through Autumn Water Dew" into his mouth.

After those few drops of clear liquid left the grass leaves, the entire plant of *Desmodium styracifolium* began to wither.

However, under the tense gaze of Chen Feng and Tang San, this precious herb did not completely wither and die, but rather declined to a certain extent, yet it still showed some vitality.

"Is this considered a success or a failure?" Chen Feng asked nervously.

Tang San sat up, examined it briefly, and nodded affirmatively:

"It's done. This 'Waiting for Autumn Dew' plant can still be used. Given the environment here, it's estimated that dew will start to grow in a few years."

"That's good." Chen Feng breathed a sigh of relief.

It's okay to wait a few years.

After checking the condition of Wang Chuan Qiu Shui Lu, Tang San sat cross-legged and began to cultivate quietly with his five hearts facing the sky.

At the same time, a faint crimson-gold light appeared on his head, and the golden light continuously gathered towards his eyes like threads.

Seeing this, Dugu Bo brought Chen Feng to the edge of the Ice and Fire Yin-Yang Well and protected him with his soul power.

The Yin-Yang Eye of Ice and Fire possesses both extremely hot and extremely cold forces, which can promote the rapid growth of plants and also have special effects on animals.

If humans or animals live near the Yin-Yang Well of Ice and Fire, their bodies will be impacted by the spiritual energy of heaven and earth of two extreme attributes. If they cannot leave in time, they will explode and die.

After Tang San awakened the Blue Silver Emperor bloodline, he is now technically in a vegetative state, but his vitality is quite strong. It is still unclear whether the Ice and Fire Yin-Yang Well will have a positive or negative impact on him.

But Chen Feng is a real human being, and staying here for too long without any protection would really be fatal.

To avoid being harmed by the unique environment of the Ice and Fire Yin-Yang Well, one must either possess powerful soul power to protect oneself, like Dugu Bo and Tang Hao, or, like Tang San in the original novel, consume both the Eight-Cornered Ice Grass and the Blazing Apricot Blossom simultaneously, and then use the spring water of the Ice and Fire Yin-Yang Well to refine one's body.

The path ahead was obviously unreliable for the time being, and Chen Feng was somewhat hesitant about the path behind.

Although both the Eight-Cornered Ice Grass and the Fiery Apricot Blossom are celestial-grade herbs, according to the original description, they are not the best quality herbs in the Yin-Yang Eye of Ice and Fire. On the contrary, their quality can only be considered ordinary, and they are also highly poisonous.

Not only that, but after consuming these two things, one must endure a period of torment before finally achieving an invulnerable body.

Compared to the celestial herbs consumed by the other seven monsters in the original story, these two kinds of celestial herbs, one ice and one fire, seem to be a little lacking.

To put it more bluntly, Chen Feng is a bit greedy; it's an old problem of his.

He had struggled with the choice of the Yin Sword many times before, and now he naturally wanted to see if he could get himself a better and more suitable immortal herb.

Judging from the effects, the immortal herbs consumed by the Seven Devils in the original novel were generally not very suitable for him, but this does not mean that there are no other immortal herbs in the Ice and Fire Yin-Yang Well.

So Chen Feng planned to consult Tang San after he woke up and ask him to help him choose the most suitable one.

Just as Chen Feng was thinking this, Dugu Bo suddenly patted him on the shoulder and said:

"Not counting the longing I just gave you, you can also pick out a few herbs here as a gift from me."

Chen Feng paused for a moment, then nodded and said:

"Thank you, Senior Poison Douluo."

He didn't stand on ceremony, because he genuinely needed it.

Dugu Bo smiled and said, "You helped me resolve my health issues, which is equivalent to saving Yan Yan's life. What are these things compared to that?"

"But when I saw Miss Dugu before, her hair was still green?" Chen Feng frowned.

Dugu Bo shook his head. "You haven't met Yan Yan before, so you don't know. Actually, Yan Yan's condition has improved a lot, and her hair color is much more normal than before."

A gentle smile appeared in his eyes. "I originally intended to give that lotus seed to Yan Yan, but she insisted on giving it to me instead, saying that she still had a chance to obtain a soul ring to continue improving her situation, but I had already reached my limit, so I should take that lotus seed instead."

"Ha, everyone knows I'm an old scoundrel who's reached the end of my rope. Wouldn't it be a waste to let me eat such precious things? This child really doesn't understand anything."

Chen Feng smiled and said, "This is Miss Dugu's filial piety. Moreover, I think what she meant by 'the end' is not that the senior has reached the end of his life, but that the senior's chance to obtain a soul ring has come to an end. That's why she gave the lotus seed to the senior."

"Yes, Yan Yan is a good child." Dugu Bo sighed softly. "It's good this way. My cultivation has improved, so I can live a few more years and take better care of her."

After saying that, he seemed to remember something and pointed to the two herbs at either end of the Ice and Fire Yin-Yang Well, saying:

"Speaking of which, those two herbs are the Eight-Cornered Ice Grass and the Fiery Apricot Blossom you told me about before. You said that taking them together could create a body that is immune to water and fire. Are you interested in them?"

"It would be a lie to say I'm not interested, but the suitability of immortal herbs is a factor, so I plan to ask Xiao San before making a decision," Chen Feng said.

Dugu Bo nodded and remained silent.

After a while, Tang San slowly opened his eyes.

In an instant, Chen Feng and Dugu Bo felt a flash of light before their eyes, and Tang San's eyes had now turned completely golden-purple, radiating a dazzling brilliance.
