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

She possesses a Foundation Establishment Ring with poison attributes, which allows her to enhance the lethality of her Serpent Staff by absorbing poison.

Of course, there is an upper limit to this absorption process; she definitely can't withstand a terrible poison like the Yama's Plaster right now.

Even the venom of the human-faced demon spider from back then, Meng Yiran has not yet fully digested, and needs to convert it into the venom of the snake staff little by little.

Once the transformation is complete, Meng Yiran's snake staff attack will be imbued with the venom of the human-faced demon spider, and its power will be self-evident.

After making arrangements for Meng Yiran, Chen Feng went to find Zhu Zhuqing and Ning Rongrong.

He was going to stay at the Ice and Fire Yin-Yang Well for a while, so he naturally had to tell the two girls so they wouldn't worry.

Fortunately, they weren't with Xiao Wu, otherwise Chen Feng would have had to explain to them why he could bring Xiao Wu but not them.

When Ning Rongrong and Zhu Zhuqing learned that Chen Feng would not be at the academy anymore, they were both a little reluctant to see him go. However, they also knew that Chen Feng was going to do something important and that he wasn't going to never come back, so they weren't too sad.

In any case, they and Chen Feng had spent little time together in the past few years, and Zhu Zhuqing had only communicated with Chen Feng through letters, so they could accept Chen Feng's departure relatively easily.

However, as compensation, Chen Feng still spent an afternoon with the two girls in Tian Dou City before the three of them returned to the academy.

The next morning, Chen Feng handed the Hydra Academy emblem he had drawn to Flander, and then called Xiao Wu to come to the academy gate to wait for Dugu Bo's arrival.

"Xiao Feng, is that Poison Douluo difficult to deal with?" Xiao Wu asked with some concern.

"Don't worry, once you get to know Senior Dugu, you'll find he's actually very easy to get along with," Chen Feng said.

"Really?" Xiao Wu was somewhat skeptical.

She had also heard some rumors about Dugu Bo and was somewhat afraid of this titled Douluo.

In fact, if Xiao Wu hadn't learned how to conceal her aura because of Chen Feng, she wouldn't have dared to show herself in front of a Title Douluo at all.

Unlike now, she actually has the opportunity to wander around right under the nose of a Title Douluo, which makes Xiao Wu feel quite excited.

Of course, this is still incomparable to her sudden encounter with Tang Hao back then, because she ran into Tang Hao unexpectedly without any means of concealment.

You can imagine what a terrifying story that must have been.

Fortunately, because of his wife, Tang Hao didn't have much malice towards the soul beasts who had become humanoids; otherwise, Xiao Wu would be buried very old by now.

Chen Feng and Xiao Wu didn't have to wait long before Dugu Bo, with black hair and a black robe, came over.

"Why did you bring a little girl with you?" Dugu Bo looked at Chen Feng with a questioning gaze.

Have you forgotten what happened yesterday? How could you just take people there like that?

Chen Feng was not surprised by Dugu Bo's question, and he explained:

"Xiao Wu knows the inside story, so please feel free to take us there, senior."

"Oh?" Dugu Bo raised his eyebrows in surprise and carefully examined Xiao Wu.

Strangely enough, Dugu Bo sensed a familiar aura emanating from this young girl.

It seemed as if we had met somewhere before.

After thinking for a moment, Dugu Bo remembered that the little girl's aura seemed very similar to that of the blue-haired boy from yesterday.

No, they are exactly the same.

What's going on? A question arose in Dugu Bo's mind.

Could these two children be related? Are they blood-related siblings?

"Senior, what's wrong?" Chen Feng couldn't help but ask when he saw Dugu Bo fall silent after looking at Xiao Wu.

"What is the relationship between this little girl and Tang San?" Dugu Bo asked, grabbing Chen Feng and Xiao Wu's shoulders as he led them toward the Ice and Fire Yin-Yang Well.

"There's a possibility that the two of them could create a Martial Soul Fusion Technique," Chen Feng said.

He didn't say anything about the three of them growing up together, because he guessed that Dugu Bo might have sensed the difference in Xiao Wu and Tang San's auras.

The Martial Soul Fusion Technique is a good answer to this question.

After all, since they can form a Martial Soul Fusion Skill, isn't it normal for their auras to be somewhat similar?

Sure enough, after hearing Chen Feng's words, the doubt in Dugu Bo's eyes dissipated considerably.

"Why is it only a possibility?" Dugu Bo asked.

"Because their martial soul fusion skills have all failed so far, they're probably still missing some conditions," Chen Feng replied.

Dugu Bo nodded and didn't ask anything more.

He had little understanding of spirit fusion techniques, so he didn't delve any further into the matter.

After a while, the three arrived at the valley where the Yin-Yang Well of Ice and Fire was located.

As soon as Xiao Wu landed, she was captivated by the wondrous sight before her.

"My God, this place is amazing."

"Xiao Wu, what brings you here?" Tang San, who was fiddling with the Blue Silver Grass, asked with some surprise.

"Xiao Feng asked me to come. He said he might need my help with something," Xiao Wu replied casually, looking at the wonderful scenery around her.

"Oh, that makes sense." Tang San recalled Chen Feng's research topic from yesterday and Xiao Wu's identity, and understood why Xiao Wu had been brought here.

Tang Hao, who was guarding the Blue Silver Emperor not far away, glanced in this direction and then looked away, not paying attention to Xiao Wu's arrival.

Chen Feng's gaze fell on the Blue Silver Grass that Tang San was fiddling with, and he asked:

"Is this the model you made based on the patterns you saw yesterday?"

Chapter 142 The Mystery of Circuits

What appeared before Chen Feng was a three-dimensional model with a somewhat complex structure.

The model is made of blue silver grass, with winding and twisting lines that eventually connect end to end, forming a strangely shaped loop.

"A circuit..." Chen Feng fell into thought.

If he wasn't mistaken, this strange circuit should contain the secrets of the Thunder Essence Stone and even the Soul Bone.

“Yes, the patterns I saw in the Thunder Essence Stone are just like this, winding and circuitous loops,” Tang San said to Chen Feng.

"Thunder Stone? When we were observing before, we couldn't see anything, could we?" Xiao Wu asked, leaning closer.

"Now that my Purple Demon Eyes have advanced, I can see them." Tang San briefly explained the matter of the Autumn Water Dew to Xiao Wu.

"So that's how it is. This place is indeed magical." Xiao Wu nodded.

"Not only is it amazing, it's also very dangerous." Seeing that Chen Feng was still thinking, Tang San explained the dangers of the Ice and Fire Yin-Yang Well to Xiao Wu.

Xiao Wu was shocked when she heard that staying here for too long would cause her to explode and die.

But Tang San then said:

"But it's alright. I can use the herbs here to make some pills. As long as you take them, you won't be affected by the environment here."

"Remember to tell me about it when you're making the pills," Dugu Bo interjected from beside the wooden house.

"Don't worry, I will." Tang San nodded to the other side.

After observing the Blue Silver Grass model for a while, Chen Feng suddenly asked:

"Mistress, what kinds of minerals do you have on you?"

"Ore? Just regular iron ore," Tang San replied. "Oh, right, the experimental board I made with the Star Soul Mithril from last time is still here."

Upon hearing the topic of ore, Tang Hao, who was not far away, looked over.

Chen Feng paced slowly, pondered for a moment, and then asked:

"The melting temperature of Star Soul Mithril is different from that of iron ore, right?"

"Correct."

Is there a big difference?

"It's still a bit large. Star Soul Mithril requires a higher temperature, but it's still within the range that ordinary forging can achieve," Tang San replied.

Chen Feng stopped in his tracks and slowly said:

"Is it possible to use Star Soul Mithril to create a model of this pattern, and then use iron to wrap and fill it, making them a single whole?"

Tang San understood somewhat, "You... want to make a model that is closer to the Thunder Essence Stone?"

Chen Feng nodded. "Yes, I want to see what this texture does and whether it can bring some special effects when applied to other materials."

"This idea is definitely worth trying," Tang San said.

“But before that, I need to conduct another experiment.” Chen Feng said, taking out a Thunder Essence Stone.

"What experiment?" Tang San asked.

"Smash the Thunder Essence Stone and see if its internal patterns change." Chen Feng placed the Thunder Essence Stone on a large rock.

Upon hearing this, Tang San was taken aback and immediately realized the strange nature of the Thunder Essence Stone.

"That's right. Thunderstone is a mined ore, and the mining process obviously doesn't follow any rules. How could the patterns in every piece of Thunderstone be the same?"

“So…” Chen Feng summoned his Tai Chi Bagua Sword, “Let’s see what’s going on here.”

After saying that, he raised the sword in his hand, his first soul ring lit up, and slammed the sword hard at the Thunder Stone.

With a "bang," the Thunder Essence Stone shattered into several large and small pieces.

Tang San's eyes gleamed with golden-purple light as he looked at the fragments of Thunder Essence Stones, a look of surprise immediately appearing on his face.

“These fragments also have patterns, and the patterns are no different in structure from those in the previous Thunder Essence Stone, only in size.”

Chen Feng, unsurprised, withdrew his martial spirit and said:

"It seems I was right. The patterns you see are not actual patterns, but rather the manifestation of some kind of illusion."

"An illusory thing?" Tang San was puzzled.

Chen Feng hesitated for a moment, unsure how to explain.

He was actually referring to the time in the original novel when Tang San's Purple Demon Eyes advanced and he saw through Xiao Wu's true form.

But this topic wasn't suitable to discuss at this time, so he could only vaguely say:

"I'm just guessing."

"I see." Tang San nodded and didn't ask any more questions.

Chen Feng had some guesses about the various characteristics exhibited by the Thunder Essence Stone, but to verify these guesses, Tang San needed to make the metal model he mentioned first.

Chen Feng believes that the so-called patterns seen by the Purple Demon Eye are related to a certain characteristic emitted by the Thunder Essence Stone itself.

Based on his previous theory of soul force waves derived from the double-slit interference experiment, he speculated that this property might also be a type of wave.

In other words, the Purple Demon Eye, having advanced to the Mustard Seed Realm, should already have the ability to distinguish some of the invisible waves it receives.

Verifying this hypothesis is actually quite simple: just see if Tang San can still see through Xiao Wu's true form using his Purple Demon Eye after she conceals her aura.

However, since Dugu Bo was present, this verification could not be done immediately.

Although Dugu Bo already knew about the Blue Silver Emperor, the Blue Silver Emperor was still a sapling and couldn't compare to Xiao Wu, a living, 100,000-year-old soul beast in human form.

It's best not to test human nature unnecessarily.

Anyway, Dugu Bo won't stay here forever, so there will always be a chance to do this verification.

After Chen Feng and Tang San finished their discussion, Tang Hao, who was not far away, suddenly asked:

"You want to forge something?"

“Yes, Dad,” Tang San said.

"Where do you plan to forge it? There are no furnaces or anvils here."

"I plan to go back to Tiandou City and borrow a blacksmith shop there."

Tang Hao shook his head. "Actually, there's no need to go through all that trouble. The forging can be completed here."

Chen Feng was taken aback, and his gaze involuntarily turned to the Yin-Yang Well of Ice and Fire. "Uncle Hao, you don't mean to say that you want to use the fire spring inside to forge it, do you?"

"Why not?" Tang Hao stood up, patted his clothes, and said.

"Dad, the spring water is extremely hot, and there's nowhere here to collect it," Tang San reminded him.

With a wave of his hand, Tang Hao conjured an anvil on the ground.

The anvil was entirely gray and looked very inconspicuous, but since Tang Hao carried it with him, it must be something extraordinary.
