After taking a few steps closer to the jade case, Shun Long's evil smile became even wider as he thought to himself

''Hehe, it is really a stalk of 'Soul poisoning hell grass'!''

This was one of the most lethal rank 5 medicinal herbs that a poison master could use to concoct poison or an alchemist could use to create rank 5 'anti-toxin pills', the 'Soul poisoning hell grass'.

Of course, not only was this grass rare to find, but it was extremely difficult to use as well both for poison masters as well as alchemists, in order to refine it into deadly poison or 'anti-toxin pills'.

Shun Long knew that the more black lines a 'Soul poisoning hell grass' had on it, the higher the potency of the poison inside it would be.

At the same time however, the level of difficulty and the danger that one would face during the refinement process would be even higher.

Even experienced gold grade alchemists didn't have absolute certainty into refining the 'Soul poisoning hell grass' into anti-toxin pills, let alone the poison masters who had to directly extract the poison inside it, before they refined it over and over again.

Additionally, the conditions for a stalk of 'Soul poisoning hell grass' to appear were extremely strict.

The body of a rank 5 magic beast or a Nascent Soul stage cultivator had to be used as natural fertilizer for more than 200 years in order for this grass to mature.

Only after the blood of the rank 5 beast or the Nascent Soul stage cultivator's had seeped into the grass, was there a chance for a stalk of this 'Soul poisoning hell grass' to appear.

After taking a look at the price of the rank 5 'Soul poisoning hell grass' however, Shun Long frowned for a moment.

350.000 low-grade spirit stones!

For a stalk of grass that can only be used to refine poison or 'anti-toxin pills', while it had an extremely high chance of killing the alchemist who refined it, paying 350.000 low-grade spirit stones was indeed an unreasonable price.

''So this is the reason why this hasn't been purchased yet. After all, a single middle-grade or high-grade rank 5 'anti-toxin pill', couldn't be sold for more than 30.000 low-grade spirit stones, so it's obvious that only poison masters would be willing to spend so many spirit stones on a single rank 5 medicinal herb.''

After thinking seriously for a while, in the end, Shun Long nodded his head before he walked in front of the jade case that held the 'Soul poisoning hell grass'.

The moment that the attendant heard that someone was willing to purchase this grass, his eyes nearly bulged out from their sockets.

After all, there were very few people in the 'City of Sin', who could afford to spend 350.000 low-grade spirit stones for such a medicinal herb that had no direct effect on their cultivation.

Even rank 1 gold grade alchemists would feel the pinch of spending 350.000 low-grade spirit stones in such a situation.

After handing the 350.000 low-grade spirit stones to the attendant and receiving the 'Soul poisoning hell grass', Shun Long first placed it in an isolated patch of grass inside the herb garden in the 'Stone of Time', before he took a look at the rest of the medicinal ingredients on the third floor of the 'Alchemists' Heaven'.

However, aside from a single rank 4 medicinal herb that could be used as a supplementary ingredient when he refined the rank 5 'Dreamy ash flower', there was nothing else that was useful to Shun Long.

Without any reason to stay here any longer, Shun Long left the 'Alchemists' Heaven' and headed back towards the northern part of the city. Barely an incense stick of time later, he arrived back in the 'Silver cross street', and completely ignoring the group from the 'Violent guardian gang' that was following him, he entered inside the first floor of the shop.

Although Shun Long could quickly take care of the 2 people who were following behind him all day, in the end, he planned to allow them a few more days to live and let them report his actions today.

He was certain that after exposing his aura at the early fourth stage in body refinement a week ago, both the 'Blood Pill pavilion' as well as the 'Violent guardian gang' would think that there was a peak rank 9 Spirit realm cultivator hidden inside the shop, and that he was also the one who took care of He Zhenkang and his team.

''Perhaps they will even think that it's a Nascent Soul stage expert.

As long as they keep observing and focus their attention on the expert inside the shop for the next few days... then even if a Nascent Soul stage expert comes by then, they will get a nice surprise!''

As these thoughts flashed through his mind, Shun Long had already arrived on the second floor where Liu Mei was still sitting on the bed with her eyes closed.

Shun Long noticed that her cultivation had already broken through to the early rank 4 of the Spirit realm, and it was actually still rising.

Of course, after absorbing the energy of a peak rank 6 Spirit realm expert, it was natural for Liu Mei to breakthrough to the early rank 4 and still have energy to spare.

After sitting on the bed as well, opposite to Liu Mei, Shun Long closed his eyes, as he simulated himself entering the foggy space in the 'Stone of Time'.

At the same time, in a busy street at the north of the 'City of Sin', inside a large building that was shaped like a castle, the pavilion master of the 'Blood Pill pavilion' was sitting on a comfortable brown couch, and was facing 2 middle-aged men in black robes with a serious expression on his face.

The 2 men in front of him were the bosses of the 'Violent guardian gang', as well as two powerful middle-stage Nascent Soul experts in the 'City of Sin', Shi Ru and Shi Hui!
