After receiving the payment, the Black Knight handed the small wooden box to Sayil, who took the box and held it tightly in his arms.

"As a partner, we can provide you with a free escort service. Do you need it?"

Sayil hesitated.

Skaven trade with the Undead, but that doesn't mean they like the Undead entering their territory.

There is still some distance between the Rat Death Border City and the Ilemaha City-State. Although it is not far, the rise of trade has attracted the attention of the surrounding horse bandits.

In the past two days, several caravans were attacked by horse bandits.

With guards, the loss is not that great.

Sayil was a small business owner and was not afraid of bandits before. The worst that could happen was that a batch of goods would be robbed.

But now it’s different. The small wooden box in his arms is all his wealth.

After thinking for a while, Sayil made up his mind and said, "I need this free escort. Please send me back safely."

The Dark Warrior nodded, "A rational choice."

After sending Sayir away, the Black Knight reported to Zhang Peng and Li Ziyu.

【Mission Completed】

[Partners have been selected]

[Soul Potion Scrap 1 has been sold]

That’s right, what Sayil bought was not the Bliss Potion Type 1, but the waste of the Soul Potion!

It was unlocked by Li Ziyu accidentally while researching technology.

The undead also have their own potions, the most famous of which is the soul potion.

For the undead, soul potion is almost a panacea.

Even if the skull is broken, using the soul potion before the soul fire dissipates completely can stabilize the dissipated soul and give them a chance to be rescued.

It works better than using soul energy directly.

Of course, this kind of potion is mostly provided to high-level undead, and low-level undead are not qualified to enjoy it.

While the undead were researching soul potions, many mistakes occurred, resulting in a bunch of extra accessories.

Most of these accessories are called scrap.

The waste materials of soul potion are not simple either. They are useless to the undead, but they are effective to the living.

Some waste can dissolve the soul of a living being, some can make the soul disappear in an instant, and some can make the soul full of pleasure.

What Sayil got was just this kind of waste, not even the best kind.

It can make the soul very active, but the duration is short-lived and, of course, the damage to the soul is not great either.

The waste materials are clearly marked as acting on the soul, making it active and bringing a sense of happiness to the living beings who use it.

But this effect is not without disadvantages. If used too many times, the soul will become weaker, not as cohesive as before, and will become easily broken apart.

Soul potions are fun, but waste materials are pretty much poison.

It was Zhang Peng's idea to sell the waste to the Rat People.

Li Ziyu reminded Zhang Peng not to let these waste materials fall into the hands of his own people, as this would destroy them.

Especially since he can't use it himself, if you want to experience it, he can provide soul potion.

Just give the scraps to the ratmen, it’s more reliable to use soul potions on your own people.

As for the resources needed for scraps... a little bit of soul energy, plus a bunch of miscellaneous stuff.

A true soul potion is not only harmless to the soul of a living being, but is of great benefit.

There is no comparison between the souls of living beings and the souls of the undead. For the undead, soul potions are used to replenish energy and heal injuries during battle.

For living beings, this is a great tonic.

Just because of the issue of soul strength, living beings only need a small amount of soul potion.

Too much is not good.

It's easy to tear the soul apart.

Long-term use of soul potions will make the soul tougher and more solid.

Under the arrangement of the Black Knight, Sayil set out with four skeleton knights and headed straight for the city-state of Ilemaha.
