Just answering a few questions is a small task for Chen Mo, and there's nothing to hide: "As far as I know, Prince Huai obtained it from the Western Regions, but as for the truth of this, I cannot guarantee?"

"Western Regions?" This aligned with what Nalan Yiren understood, she continued: "How did Duke An find out about this?"

"From a courtesan named Zhihua."

"Where is she?"

"In Linzhou. But as far as I guess, regarding Immortal Powder, she doesn't know much either."

Nalan Yiren narrowed her eyes slightly, but quickly caught a key piece of information from Chen Mo's words and hurriedly asked: "What about Prince Huai?"

Since Prince Huai obtained it from the Western Regions, he should know where that person is hiding there.

"Underground," Chen Mo said.

"Hmm?" Nalan Yiren glanced down.

"When I say underground, I mean he's no longer alive."

"Ah?"

A trace of panic appeared in Nalan Yiren's eyes. She wasn't worried about the death of Prince Huai, but was concerned that with Prince Huai dead, it would be very difficult to find that person's trail.

"Duke An, apart from Prince Huai, is there anyone else who might know that person's whereabouts?" Nalan Yiren asked.

"That person?"

"To be honest..." As she spoke, Nalan Yiren walked to the window and looked at the heavy rain outside: "Have you ever heard a rumor about a direct disciple from Poison King Valley who murdered his master and was exposed, then killed by the elders of Poison King Valley?"

Chen Mo was stunned; he'd heard Wu Mi mention this rumor before and nodded briskly.

"This person's name is Tang Yichen, the senior disciple among all the direct disciples of Poison King Valley, and the master he killed was my grandfather Nalander. After the affair was exposed, he was besieged by three elders in the valley, struck a Poison Palm from the Great Elder, then escaped from Poison King Valley and since disappeared.

But Poison King Valley has always investigated his whereabouts. Later there were rumors that he became the High Priest of the Western Regions, and upon hearing the news, Poison King Valley immediately sent a large number of experts to the Western Regions to search. However, the Western Regions are vast, with a lot of desert and few people, so they found nothing. 𝗳𝗿𝐞𝕖𝘄𝗲𝕓𝗻𝚘𝚟𝕖𝐥.𝚌𝕠𝕞

Many in the valley think this rumor is false, believing that he was struck by the Great Elder's Poison Palm and could not live for more than three months without the Taotie Gu. Until we received news that Great Song Jiangnan discovered Immortal Powder.

The secret formula of Immortal Powder has always been a concealed secret within the valley, and only those who cultivated the exclusive Poison Technique could prepare it. In this world, besides Poison King Valley, only him, he's still alive..."

After speaking, Nalan Yiren's gaze turned gloomy and her voice icy, tinged with gritted teeth.

The sound of rustling arose.

It came from within Nalan Yiren's black robe.

The next second, groups of poisonous snakes, ants, scorpions, and bees crawled out from under Nalan Yiren's robe.

If ordinary people saw this, they would faint on the spot.

Chen Mo and Yue Ruyan also stepped back a bit.

Not out of fear, just a touch of trypophobia.

But after listening to all that Nalan Yiren said.

Chen Mo quickly understood that as the granddaughter, she wanted to find Tang Yichen to avenge her deceased grandfather.

So she came to Great Song personally, hoping to get clues about Tang Yichen from him.

Yet he also knew only bits and pieces.

The real possibility of knowing Tang Yichen's specific whereabouts lied with Prince Huai, who obtained the Immortal Powder.

Only now, Prince Huai is dead.

If what Nalan Yiren said is true, integrating her words, one's emotions might also be somewhat unraveling.

"Miss, you need not worry like this, though Prince Huai is dead, it's not the case that besides him, no one knows of Tang Yichen's location," Chen Mo said.

A glimmer appeared in Nalan Yiren's icy eyes: "You know?"

"I don't know, but those under him might know a thing or two."

"Hmm?"

"Think about it, with Prince Huai's status, he certainly couldn't personally travel thousands of miles to the Western Regions to buy poison from Tang Yichen, he would surely send someone beneath him..."

Saying this, Chen Mo slightly smiled, "If luck favors us, perhaps this person is in my army or imprisoned."

During Prince Huai's several defeats, Chen Mo captured many under him.

Such as Diwu Fusheng and Liu Ji are both in the army.

"Duke An is willing... to help me?" Nalan Yiren asked, half-believing, as this was more than just asking a few questions.

Chen Mo glanced at Nalan Yiren a few times.

This made Nalan Yiren frown, thinking the other side was interested in her, as she had heard rumors about Duke An being licentious.

But she dressed like this, besides being accompanied by poisonous creatures.

Could he really be immune to fear?

Just as she prepared to use some techniques from Poison King Valley to try to control the other.

Chen Mo blinked and said: "Of course, I can. Moreover, if I truly find Tang Yichen's whereabouts, I can personally assist you in avenging this blood feud."

Nalan Yiren raised her eyebrows: "What is the price?"

There is no such thing as a free lunch.

If it's free, Nalan Yiren wouldn't believe it.

"It's simple, I help you, you have to help me as well." Chen Mo said.

"Hmm?"

"I suppose you know well enough, Great Song is at war now."

"Poison King Valley never involves itself in external conflicts, let alone foreign wars." Nalan Yiren guessed what Chen Mo was about to say.

Though Poison King Valley is powerful in the martial world, within the valley are only about a thousand disciples including elders, and Baiyue is just a small country, hard to withstand a powerful army.

Eventually, potent poison has its environmental requirements.

Firstly, it needs an enclosed space, less air circulation, otherwise the potency gets reduced.

Which is hard to achieve on such an open battlefield.

Unless infiltrating the enemy camp, poisoning their meals.

But that's also hard.

Even an Upper-Grade Martial Artist can't fly or burrow.

With a heavily guarded camp, sentry posts every five steps.

Invisibility would be needed, otherwise impossible to poison in the mess discreetly without detection.

Thus, once Poison King Valley gets involved in such external power struggles, if Chen Mo's side ultimately loses, Poison King Valley would certainly face retribution.

"In that case. I've heard Poison King Valley has a sacred object called Taotie Gu, if Miss can offer it as reward, then I will wholeheartedly assist you," Chen Mo said.

Upon hearing this, Nalan Yiren's gaze grew colder, her feet's poisonous creatures influenced by her emotion, also displayed a stance of frenzy.

Nalan Yiren icily said: "Do you know why he killed my grandfather? It's because he wanted to obtain this Taotie Gu, and in refusal, killed him, planning to forcibly seize it, unbeknownst to him that Taotie Gu is a master-recognizing entity. Even if I give it to you, it won't heed you."

"But aren't you considering offering nothing?" It's not just answering a few questions; naturally, Chen Mo wouldn't assist without compensation.

"Of course not. Though Poison King Valley relates to poison, its medical skill is unrivaled; if your family has someone gravely ill or infertile, I can treat them, guarantee cures.

Moreover, Poison King Valley has an elixir to delay aging, making women more beautiful, if you're willing to help, these are all yours." Nalan Yiren said with some pride.

Upon hearing this, Chen Mo blinked, pondered, and said: "In that case, I can assist you. But only by finding Tang Yichen's exact whereabouts; revenge must be sought by you alone."

"Deal."

Nalan Yiren never intended for Chen Mo to help kill Tang Yichen.

"Then when the rain stops, follow me to the army," Chen Mo said.

Nalan Yiren showed a cautious expression.

"Rest assured, although I am no saint, I am not a villain either. If I wanted to harbor any ill intent towards you, there's no need to head to the army. You wouldn't be able to handle me." Chen Mo said.
