In addition to a large number of magic crystals in the ring, there are also a lot of miscellaneous materials, as many as more than a hundred, many of which Aaron has seen for the first time, so he deliberately asked the chip to check in the database.

However, after checking, nearly half of the materials still didn't figure out what they were, and those materials that were already known were relatively precious.

Among them, Aaron also found several materials that he needed to make his own potions, and there were many of them.

There are also a lot of necessary materials for making the Banshee Veil, and after getting the incomplete Banshee Veil alchemy materials from the first opening, because some of the materials are too difficult to find, Aaron has been trying to find a way to find a replacement, but unfortunately there is not much progress, and it has been shelved in the middle because of some other things.

Therefore, the day of making the Banshee Veil is still far away, and now there are a lot of materials in it that are exactly what is needed, and it is estimated that it will not be too long before he can officially taste the Banshee Veil instead of making defective products.

Defective products like those made by Pascal no longer mean much to Aaron now, and they still have to make real banshee veils to be useful.

After checking the contents of the ring, Aaron took it back to his finger and thought: "The fourth potion is still one material missing, I don't know what the final result will be on the mercenary union's side?"

In the ring, Aaron found some materials needed for the fourth level, all of which he didn't have, and if you add them up, there is still the last material missing.

This last material is not very difficult to find, and Aaron hopes that someone can find this material in the previous mission issued by the Mercenary Guild, and then he can start making potions.

Time flickered, and finally the last day of the mission deadline came.

Early this morning, Aaron went to the mercenary guild to see how the mission went. He had been here once two days before, but no one had come to submit the assignment at that time.

The deadline for the quest is in the afternoon, and if no one has completed it by then, you can only cancel the quest and continue on your way, waiting for the next chance to collect the last material.

Aaron walks into the mercenary guild. I went straight to the place where the mission was last posted, and I also met Harrison, the person in charge there.

Harrison was sitting idly, yawning and seeming to be sleepy.

"Harrison, how is the status of my posting mission, has anyone come to submit the mission in the past two days?" Seeing Harrison, Aaron greeted him and immediately asked about the mission.

"It's Lord Aaron, and you've come just in time. Yesterday evening, one of the mercenaries brought three of these materials, and I have already put them away!" Harrison immediately picked up his spirits and replied when he saw Aaron coming.

"Well, those three materials, how many are there?" Aaron asked expectantly as soon as he heard that someone had found three materials. Hopefully, there is the last one you need.

"Those three materials are the coccy......x of the black bone worm," Harrison heard and immediately told Aaron about the three materials.

As for remuneration. He has deducted it from the deposit he had previously submitted and paid it to the person who submitted the documents.

"Very good! The tailbone of the black bone worm, it's the worst!" After listening to Harrison's words, Aaron was secretly happy in his heart.

The last material that Aaron had left was the tailbone of the Black Bone Worm, and now he had finally gathered all the materials for the fourth potion. It's time to start making hands-on production.

Soon, Harrison went to fetch all three materials and handed them all over to Aaron.

Aaron took a large bag and didn't put it in the spatial ring, but carried it out of the mercenary guild. Because of such a thing as a space ring, he can't let people know casually at the moment, otherwise with his current ability, it is impossible to keep it.

Care must be taken when using it, and it should not be seen under the general order Aoi Aoi.

In order to be safe, Aaron deliberately found someone a few days ago, and according to the appearance of the ring, he customized a ring that looked similar to the same and wore it on the other hand to hide people's eyes and ears.

Now that all the materials for the fourth potion have been gathered, Aaron is not in a hurry to leave Daga City, but is going to stay here for a short time, make the potion, and see how it turns out.

"It's finally worked!" Aaron let out a long sigh as he held the potion in his hand.

After nearly a day of tinkering in the carriage, Aaron finally managed to get the first potion, which had failed many times before and wasted some of the materials.

Aaron then fed the potion to the test subjects, quietly observing their changes.

A day later, Aaron in the carriage looked at several dead test subjects and couldn't help frowning: "The side effects really exist, and they are not small!"

At this time, none of the test subjects who had been fed the potion survived, and all of them had died, and a few of them had survived after being fed the first three potions, and they had also been greatly strengthened.

But even so, it can only last for a day at most, and judging from the current results, the side effects are so great that Aaron doesn't dare to use it at all.

"It seems that the accumulated blood can only be used, and I don't know if the new thorn vine will have any effect!"

The side effects are still very large, which Aaron has been prepared for, and the current results are not unexpected.

The blood collected from Black is enough to breed new thorn vines, but Aaron doesn't have any bottom in his heart, and new thorn vines may not be able to eliminate the side effects.

But whether it works or not, you still have to try to know.

Soon, Aaron took the collected blood out of the spatial ring and threw a seed into it.

As soon as it comes into contact with a large amount of blood, the seeds grow wildly, until finally, when there is a little bit of blood left, the thorn vine finally stops absorbing and officially grows to the limit.

The new thorn vine was named the Five Generations Mutant Thorn Vine, and Aaron immediately cut out a small part of it, processed it according to the old method, and put it into the production of the fourth potion.

When the potion was crafted again, Aaron fed a new batch of test subjects.

However, the results of the second day were still much disappointing for Aaron, and all the test subjects were hung up again, which meant that the new thorn vine could not eliminate the side effects.

According to Aaron's preliminary estimates, there may be two reasons, one is that the strength of the thorn vine is not enough, and a more powerful thorny vine is needed as a material to eliminate the side effects.

The second is that the thorn vine can only eliminate the side effects of the first three agents, and it is ineffective against the next two, no matter how strong it is.

The first possibility is relatively large, the second possibility is relatively small, in short, for the time being, Aaron has no other way but to wait for the future to continue the experiment. (To be continued......)
