"By the way, Bruce, I have one more thing to trouble you?" Aaron continued after talking about the mandala flower. He came to Bruce this time, not just for the mandala flower.

"If there's anything else you want me to help with, just say!" Bruce said yes, looking enthusiastic.

"I've been doing some real things recently, I need the blood of some more powerful creatures as samples, can you help me find some, the stronger the owner of the blood, the better, you see that this shouldn't be as difficult as the mandala flower......"

In the past three months, Aaron has been researching the mutant spiny vine seeds, and has also obtained three kinds of blood that agree to make the seeds grow, but the owner of these bloods is not as strong as the berserk lizard, and the new seeds that grow as a result are not as strong as the second generation, some are even weaker than the first generation, and the other two are in between.

What Aaron needed was stronger seeds than the second generation, which obviously did not meet his standards, and after these several studies, he was sure that the stronger the blood master himself, the more powerful the new generation of seeds he cultivated.

In the face of the berserk lizard, Aaron feels that he has a certain risk alone, and he wants to pay too much attention to those creatures that are stronger than him, first, because of the risk, second, it is a waste of time, and third, after a successful kill, the blood obtained may not be useful.

Based on these factors, Aaron feels that this matter is still for Bruce to help, he has a family behind him, and he may be able to provide enough help to himself in this regard.

"Is it the blood of a powerful creature? Although this is not easy to get, it is indeed a lot simpler than the matter of the mandala flower, no problem, it is wrapped in me, I am also going back to the family in two days, I will explain it to my grandfather, and help get some samples for you." Bruce was obviously more confident in this matter, patting his chest and reassuring.

Now Aaron spends an hour every day to guide Bruce, so he owes Aaron a lot of favors, and these two things will naturally be done with his heart, and this is also a bridge to build a relationship.

After explaining the two things, Aaron didn't stay long, chatted casually, and returned to the treehouse.

For the next half month, Aaron continued to study a lot of potions every day, waiting for news from Bruce's side.

"Calculating the time, it's been almost 12 days since Bruce went back, and I don't know when I'll be back. Today, as usual, the days of waiting made Aaron feel like it was going by slowly.

Just as Aaron was about to start making a new potion, there was a knock on the door, followed by Bruce's voice.

"Finally back!" As soon as he heard Bruce's voice, Aaron immediately put down what he was holding and walked quickly to open the door: "You're finally back, how are those two things?"

As soon as he met Bruce, Aaron couldn't wait to ask how it was going.

"Let's go inside and talk. Bruce smiled faintly, walked into the room, and casually found a chair to sit down: "There is no news about the mandala flower for the time being, but if you want to improve your mental power, I have asked my grandfather to help, see if I can get you a copy, I have to wait for a while to see if it can be done." ”

"It seems that the first thing is that there is still some hope. Bruce's answer gave Aaron a glimmer of hope, and his mood suddenly improved.

"And what about the other thing?" Aaron then asked.

When Blue heard this, he smiled, and it seemed that this matter was going very well: "You can rest assured about this, I have already helped you get some blood samples back, and I will have someone send them to you when I turn around." ”

"Oh, how many blood samples did you get, and how much of each?" Aaron nodded with satisfaction with the result.

"Well, there are about seventeen or eighteen, I haven't counted the specifics, one of them is only a small bottle, but the other portions are very sufficient, enough for you to do as much as you want. Bruce recalled, quite with certainty.

After the two chatted a few words, Bruce hurriedly left: "I have to leave first if I have nothing else to do, I will go straight to you as soon as I come back, and I haven't reported to Mr. Wren yet, I have to go over immediately......

"Then hurry up and find the teacher, or you'll be scolded again!" Aaron couldn't help but shake his head and smile.

A few hours after Bruce left, two strange apprentices came to Aaron and brought the blood samples. Counting them closely, there were seventeen samples in total, except for one, as Bruce had previously said, only a small vial.

The rest of the blood has a large tank, a dozen liters, the amount is quite sufficient, in fact, the blood sample only needs a few drops is enough, the reason why I want to come to these is that Aaron wants more samples, to study the composition of the blood, what factors determine whether the seeds can be absorbed, and what factors determine the strength.

But so far, Aaron has not made any progress in this area of research, and is in a troubled predicament.

As soon as the blood sample arrived, Aaron immediately moved his hand, took out a mutant thorn vine seed, held a straw, sucked a kind of blood, dripped it on the surface of the seed, and quietly observed whether there was any change.

"Whew...... Still can't do it!" A few drops of blood dripped on the surface of the seed, and he waited quietly for a few minutes, without the slightest change, to which Aaron sighed helplessly.

After wiping the blood on the surface, he looked at the remaining blood samples and said with a sad face: "There are only the last two left, and all the 15 samples in a row are invalid, this luck is not ordinary!"

After lamenting that his luck was extremely bad, Aaron continued with the last two operations.

The next meal still failed, and Aaron's mood was extremely disappointed all of a sudden.

The last blood sample, the one Bruce said, had only a small amount.

"Huh, unknown creature?" Looking at the expression on this small test tube, Aaron couldn't help frowning, the labels on other blood samples all stated which creature the blood came from, but this one had the least amount of weight, but there was no detailed information.

Although it is not clear what kind of creature this blood comes from, Aaron didn't think about it that much, and if he couldn't let the seeds grow, there was no need to pursue this question.

Disappointing more than a dozen times in a row, Aaron held an indifferent mentality, dropped a few drops of the blood of unknown creatures on the seeds, and watched nonchalantly.

"Haha, it finally works!" However, as soon as the blood touched the seed, it was quickly absorbed, and then a small shoot grew, and the sudden change made Aaron feel energetic all of a sudden.

Then a few more drops of blood dripped down, agreeing to be quickly absorbed, and after a while, the blood sample of the unknown creature had been half used, and the vine had grown to half a meter long.

At this time, it is possible to distinguish the strength of the bottom vine, and compare it with the previous data in the same state, and deduce how much the final strength of the vine can be increased after it is fully grown.

"Chip, scan this sample, compare it with the number of jù collected before, and the analysis results are ......" Aaron immediately gave instructions to the chip.

"The scan is complete, and it is being compared and analyzed with the number of ...... databases."

"The task is completed, the current intensity of the sample is 6, according to the comparative analysis of the number jù, it is estimated that when the full growth is completed, the intensity will reach 13, and the error is within 2......"

Hiss!!!

When Aaron heard the feedback results, he subconsciously gasped: "Now the strength has reached 6! When the strength is fully grown, the minimum strength can reach 11, and the maximum can even reach 15!"

"What kind of creature is this, it's so powerful! Far more than the blood of the berserk lizard I've found before, no! I have to find out what kind of creature blood this is. He was thrilled that the blood that was least favored by Aaron had a surprising effect.

The second-generation mutant thorn vine seeds, after completing the growth, are only 7, and the blood of this unknown creature, the effect far exceeds this suzhì, if you get a lot of blood and cultivate the third-generation seeds, then the power of the spell will definitely be greatly improved, and the power of breaking through 5 degrees is very hopeful!

After carefully putting away the remaining half of the blood samples of unknown creatures, Aaron immediately ran to find Bruce, and at this time he happened to have returned from Wren.

"Huh, what is Aaron looking for me, aren't you satisfied with the blood sample you sent before?" Bruce looked puzzled when he saw Aaron coming to him again so soon.

"I'm very happy with the samples you brought me, but the small amount of blood, the label doesn't say what kind of creature got it, I found this kind of blood sample very helpful to me, can you help me figure out what kind of creature it is?" Aaron said and went straight to the point.

"It turned out to be this kind of little thing, no problem, wrap it up on me, I'll help you ask it when I get back. When Bruce heard this, he felt that it was just a small matter, and he didn't hesitate to pack a ticket.

"Okay, then I'll wait for your good news!" Aaron said lightly.

Two days later, news finally came from Bruce's side, but Aaron was not very happy with the news.

According to Bruce, the blood was obtained by one of his cousins from an injured unknown creature in an accident, and the creature's general appearance is known, not its true origin.
