When, when......

The melodious hourly bell rang out, and in the sewer, Su Xiao held the dragon slaying flash in the sheath with one hand, and more than ten meters in front of him, there was a raging flame.

Looking at the existing prestige, 529 points, the rats in the sewers of the Bone Harbor no longer dare to rush out, no matter what medicine Su Xiao used to lure them, they were obviously afraid of being killed.

Su Xiao came to a relatively intact giant mouse corpse and extracted a small number of cells, he tried to use the green steel shadow to devour these cells, under normal circumstances, the green steel shadow could only devour energy.

Zila~

The blue arc flickered, and the cells of the giant rat quickly turned to ashes.

"It's ......"

Su Xiao just wanted to try it, but he didn't expect that there was indeed a gain, these mice were not mutated, but some kind of energy combined with their cells, which caused them to be so huge.

Compared to the reason for the gigantic mouse, Su Xiao was more concerned about another thing, he raised his right arm, and the entire back of his hand, including the skin of some of his fingers, became pitch black, and this pitch black spread in an erosive state.

If left unchecked, this pitch black would invade Su Xiao's body at a very slow speed, and as for its origin, every time Su Xiao killed a giant mouse, the pitch darkness on the skin on the back of his hand would expand a little.

As for using the Qinggang Shadow energy to devour, it is completely possible, but the mana to be consumed is too much, and the Qinggang Shadow energy converted by consuming 8000 mana points can probably devour the pitch black in an area of one centimeter, and it can be devoured, which means that the level of the Qinggang Shadow energy is higher than this pitch black, but this pitch black has a root, a very large root.

Su Xiao moved his right hand, basically no effect, if he guessed correctly, this is the 'darkness' that the Daughter of Sorrow said before, the sentence 'I will help you dispel the darkness' is not an encouragement, but something that the Daughter of Sorrow can really do.

The Daughter of Sorrow also said that she would not harm any living beings, which is also worth pondering, in other words, harming living beings in this world will be eroded by darkness and eventually become monsters?

Or, as a sad woman who can clear the 'darkness', she can't accept the darkness herself, otherwise she will lose the ability to clear the darkness?

With the side effects of potions, plus the erosion after killing living creatures, it's no wonder wizards go crazy.

"I see."

Su Xiao glanced at the pile of burning rat corpses, he was not going to continue cleaning up the rats, the efficiency was too slow, he came here just to verify some conjectures, and this time it can be said that he has gained a lot.

Su Xiao returned the same way, left the sewer, climbed the iron ladder and went straight to the wizarding club in the Holy Silver District.

When Su Xiao returned to the Wizarding Society, Caesar at the reception of the Wizarding Society was busy.

"So fast?"

Caesar looked at Su Xiao with some surprise.

"I'm not interested in helping wizards clean out rats anymore."

“！”

Caesar shuddered and subconsciously covered his pocket.

"Are you trying to ......?"

Caesar swallowed his saliva and suddenly panicked.

"Your proposed forcible exchange of prestige for potion recipes is not feasible and risky......"

"Wait, wait, what you're about to do is more risky! There are at least more than 200 arcane wizards here, and we can't be scared at all, and even if we really settle this, we will be wanted by wizarding councils everywhere. ”

Caesar looked at Su Xiao with frightened eyes, and Su Xiao looked at Caesar suspiciously.

"Did I say I'm going to settle this?"

"Eh~ That's no, it's just your words, don't say that the Wizards Club is leveled, even if you say that you want to slaughter Heru City, I feel that you have done it."

Caesar nodded thoughtfully.

“……”

Su Xiao was speechless for a while, in terms of external combat power, the Wizard Guild should be the strongest force group in this world, but their strength is too fast, it is likely that when dealing with some existences, they don't even have a chance to resist, before going to clean up the rats, Su Xiao generally verified this.

"Caesar, the wizards' potions don't appear out of thin air, according to what you said, potions are in high demand and are produced independently, who concocts them?"

"The Moen family."

Caesar breathed a sigh of relief in his heart, he was really afraid that Su Xiao would draw his sword and the wizard would be tough.

"Where are they?"

"It's just nine floors upstairs, you don't want to...... The Moen family isn't easy to mess with, either. ”

"Oh."

Su Xiao patted Bu Bu Wang's head, Bu Bu Wang understood, directly integrated into the environment, and bumped Su Xiao lightly, so that Su Xiao could see it.

Su Xiao took out the wireless earphones, threw one to Bu Buwang, and put one on himself.

Bu Buwang took out the whole set of monitoring equipment very skillfully, walked out of the small door, and ran upstairs.

"Good, so skilled......"

Caesar was stunned, he looked at Su Xiao very seriously, and seemed to have reacquainted himself with this old friend.

"A group of wizards who have been eroded by alien energy to the point of confusion, fighting with them to the death will only waste physical strength."

Su Xiao took out his tablet, threw a wireless earphone at Caesar, and said, "Tell Bubu where the Moen family's potion is exactly located." ”

Caesar poked his head over, glanced at the screen on his tablet, and began to help Bubuwang guide him.

From the very beginning, Su Xiao had no intention of risking the potion formula, as for the way to gain prestige by mixing potions, it was indeed desirable and efficient.

According to Caesar, it costs silver coins to buy potions, but drinking potions and the subsequent process, as long as you join the wizarding club, you can enjoy it for free, this is the rule set by the immortal wizard Dawn, no wizard dares to violate it, including the Moen family, they are only responsible for mixing potions, in the final analysis, they are only important members of the wizarding club, at best they are high-level.

With the composition of the Wizards' Society, as long as they don't attack here, it is impossible for the wizards to unite, they are used to being casual, and it is completely impossible to make them desperate without touching their own interests.

Therefore, before that, Su Xiao had speculated clearly that mixing and selling potions would only offend the potion conpensator, not be hostile to the wizarding society, before he went to clean up the rats, first, he wanted to reconnoiter the terrain of Heru City, so as to facilitate a strategic retreat at a critical moment, and secondly, to find out the attitude of the wizarding society towards wizards and civilians.

The screen inside the tablet changed rapidly, and after a few minutes, Bubuwang arrived on the ninth floor of the Wizarding Society, ignoring dozens of alerts.

Bubuwang stopped in front of a metal door with an Ouroboros motif, a emblem representing the Moen family.

Bubuwang activates the Holy Traveler, piercing directly through the wall and entering a pitch-black room.

Airplanes~

The night vision device is activated, and Bu Buwang looks around, which is a room of more than 200 square meters, with rows of bookshelves, and a metal table in the corner of one side of the wall, on which bottles and cans are placed.

For this kind of business, Bubu Wang can be said to be quite proficient, and it did not rummage through the cabinets to find it, because the secret item such as the potion formula could not be kept in a physical way, and Bubu chose to wait.

After waiting for more than seven hours, the door was pushed open, and a gray-robed figure walked into the room, his hand waving in front of him from time to time, as if to repel mosquitoes that didn't exist.

After waiting for more than half an hour, the figure in a gray robe and hood sat in front of the metal table, took out several materials from the drawer of the metal table, and began to mix.

Bu Buwang approached the camera, and Su Xiao on the other side watched carefully.

In less than a few minutes, a bottle of pure black potion was concocted.

"It's okay, Bubu, the potion is easier than you think, and this clumsy technique can be mixed ......"

Hearing Su Xiao's words, Bu Buwang came to the wall very leisurely and came out through the wall, and the figure in the gray robe didn't notice anything unusual at all.

Su Xiao put away the tablet and turned his gaze to Caesar.

"Can you get those materials?"

"Huh? Yes? Yes! ”

Caesar looked at Su Xiao with a bewildered expression, as treacherous as him, and was also stunned by the cooperation between Su Xiao and Bu Buwang, he had a feeling that if he was hostile to Su Xiao, he would be arranged to be clear, and he didn't know how he died.
