Su Yan was very nervous.

She had heard that the Ironblooded Heroes Guild was the strongest Heroes guild in this area.

Their leader is also terrifyingly strong.

All the Heroes within several hundred kilometers with the strength or potential have been invited to join, and most of them had already taken up that invitation.

They're extremely ambitious and very vicious in their methods.

If she gets seen through, the consequences would be unthinkable.

Su Yan spoke, "I don't actually know that much about the situation. All I know is that it might be a Demon King of the undead."

The tiger-kin Hero's gaze sharpened, "An undead Demon King? What's his actual strength? How big is his army? Talk! Quickly!"

"When boss Zhao Lei took us to subjugate the Demon King, we got ambushed in the Darkness Valley. The enemy forces probably number around one to two thousand. The battlefield then was really chaotic, so I wasn't able to see the Demon King's actual capabilities."

Su Yan gave a report on Zhao Lei being ambushed.

Her words had lies mixed in with the truth. Due to the fact that the battle didn't actually take place within the Darkness Valley and the fact that she hid the critical information, she wasn't considered to have violated the contract.

A bear-kin hero let out a cold chuckle, "Even Zhao Lei died, and yet you somehow survived? I'm thinking that there's probably something suspicious there!"

He then addressed the tiger-kin, "By my views, this guy is either a cowardly deserter or a bait that the Demon King purposefully let escape. We're better off just killing him, just in case."

Su Yan was terrified by those words.

The tiger-kin Hero leader rejected that idea though, "No matter. So long as he can provide us with information, even if it's only partial, it's still worthwhile!"

"Besides, he's been to the Demon King's base before, and we do need a guide. There's use in keeping him around."

Su Yan hurriedly begged for mercy, "Bosses, please let me off. I only just got away here, so I really don't want to go back again!"

"Shut the fuck up!" The tiger-kin leader showed a cold smirk, "You'd best be good and obedient. That way, you'd at least have some chance of living. Otherwise- Hmph!"

When Su Yan heard those words, she started coldly smirking as well in her own mind.

Those guys are no decent people, as expected.

They've decided to use her, to have her lead them and die as cannon fodder.

The bear-kin commander asked, "Based on his description, although Zhao Lei did lose quite badly, the Demon King seemed to have taken a lot of losses as well. Should we attack ahead of time then? After all, it's only been a few days since then, so the Demon King shouldn't have fully recovered yet."

The tiger-kin leader shook his head, "Zhao Lei died due to recklessness and underestimating his enemy. We can't follow in his footsteps. Let's wait a few more days!"

The wolf-kin commander agreed as well, "That's right, so long as the guildmaster or the deputy guildmaster gets here, then no matter how capable that Demon King is, he'll still definitely end up as our trophy in the end."

"Let's first hash out a plan. It's best if we can avoid the heavily defended canyon and instead enter the Valley via the air, a river or by some other route before directly destroying the Demon King's Nest!"

"As for this guy... Lock him up for now."

"Don't let him escape!"

"Set up a few extra guards!"

"Make sure they keep a close eye on him!"

Su Yan was taken away without any chance to object.

It was unavoidable for her to feel a hint of worry when she heard the Ironblooded Heroes make their battleplans.

Those Heroes leading the group are all at a similar level of power as Zhao Lei. Plus, all the subordinates they brought are also elite troops and there was even supposed to be a lot of reinforcements behind them.

Plus, unlike Zhao Lei, they were extremely careful.

They were even planning to completely bypass the canyon.

The Great Demon King has probably finally met a real challenge now.

Su Yan had no way of getting back to report. Those Heroes won't let her escape. Thankfully though, she had long since prepared for that, and while no one was paying attention, a tiny bat slipped out of her pocket and left the secret camp without anyone noticing.

...

Darkness Valley.

Demon King Castle.

Mysterious Witch Liang Bai: "Boss, the first batch of potions have been completed."

Zhang Nu: "That fast? Show me!"

The Mysterious Witch sent two different potions.

[Life herb potion]. Upper green quality. After consumption, recover 25 HP over 10 seconds!

[Moonlight recovery potion]. Upper green quality. After consumption, recover 40 MP over 10 seconds!

That's some really good quality!

It's completely different from consuming the herbs directly.

Although the herbs also have similar effects, it takes some time before they come into effect and the recovery speed is also slow. Their actual worth in battle is fairly low.

After being made into potions, they'll immediately start taking effect after drinking and the full effect will be completed within 10 seconds.

This makes it so that they can practically save one's life in a pinch!

It's a must have for any traveling, something with very high value in actual combat!

Zhang Nu asked: "How much do you plan on selling?"

Mysterious Witch Liang Bai: "I plan on selling the life herb potion for 150 gold and the moonlight recovery potion for 200 gold. For you, I can especially give you a discount of 50 gold!"

That's quite expensive!

Even so, it's not a bad price either.

Currently, there's a lack of potions on the market. It's a matter of life and death, so any Demon King with the ability to buy them will definitely keep 3-5 bottles on them at all times. The demand for it can be said to be extremely huge.

The Mysterious Witch's discount also shows plenty of sincerity.

This is because she needs to buy the ingredients from Zhang Nu.

Mysterious Witch Liang Bai: "If you think that this is fine, then I'll first repay my debt now. In the future, I'll also make sure to let you have the first chance at buying them!"

Zhang Nu: "No problem!"

Potion making really is profitable.

There's enormous demand in the market for it just waiting to be filled.

This made Zhang Nu kind of want to go grab some potion makers of his own.

What races are good at potion making? It seems like elves and the like tend to be good at it.

In the end, after some discussion, the Mysterious Witch handed over 20 moonlight recovery potions and 10 life herb potions to repay the debt she owed for buying the ingredients before.

Zhang Nu also made an agreement with Liang Bai.

He'll be getting first shot at her products, as well as the best services.

Zhang Nu promises not to disrupt the market via reselling the potions. At the same time, he'll also be giving Liang Bai some discounts when supplying ingredients to her.

Thus, the two Demon Kings formed a cooperative relationship.

This can be said to be a mutually beneficial deal.

Although Zhang Nu is quite tempted by the potions market, he's not actually jealous over the Mysterious Witch's small profits. This is money that she earned using her own abilities after all.

Besides, based on the actual investment and returns, it's quite obvious that right now, farming is the true path for him.

After Zhang Nu finished his discussion with the Mysterious Witch, he received the news that Su Yan had sent him via her transmission bat.

"What?"

"A huge group of Heroes have gathered nearby?"

Rather than worried, Zhang Nu was quite overjoyed. Aren't they basically EXP bundles being delivered right to his doorstep? The stronger the Hero, the better quality their Souls are!
