After visiting his parents, the two returned to the academy together, and since he knew the rule of leaving the hospital after graduating ten years ago, Su Ze had a sense of urgency, as if this good time of quiet cultivation would be fleeting, and he was forced to plunge into the long and endless secular struggle, and the Jin Dan period was one step further away from him!

On the third day of class, Tutor Catherine gathered all the new Level 3 magicians to inform them of the incident, and suggested that Su Ze and the other student could consider the patrol team in the school. Yes, only Su Ze and another dark student he didn't know were summoned who seemed to be in the same class as Eric. The student was very excited and agreed, but Su Ze was noncommittal and did not express his position on the spot.

When Catherine finished speaking and announced the disbandment, she saw that Su Ze was still standing in place and looked like she had something to ask, Catherine said, "What's the matter, what's the matter?"

"May I ask the mentor, what should I do if I want to exchange some magic materials from the academy's secret vault?" Su Ze said.

"Just go directly to the finance office of the department to apply, but there may not be magic stones there, most of the good things are bartered, you have to be prepared. What do you want to change?" said Catherine, who was used to this kind of thing, but she couldn't help but ask if this guy was unexpected.

"Whispering Leaves, Flame Tree Cores, Sage Bones......" Su Ze said casually, these materials are versatile, and they do not reveal their intentions.

Catherine was secretly surprised when she heard this, these were all third-level materials, and they were worth a lot of money, so she didn't know what he was going to do. However, Catherine did not ask, and seeing that Su Ze had nothing to ask, she turned around and left.

The finance office of the department is not in the mage tower, it is a three-story villa with a single courtyard, which is similar to the student dormitory. Su Ze looked at the bearded magician on duty and said, "May I ask if there are Whispering Leaves and Flame Tree Cores in the secret vault of the Adult Academy?" I am a student of the Dark Department and want to exchange for a copy. ”

The bearded magician lazily hid behind his desk, leaned back in a comfortable position, glanced at Su Ze and said, "There are all in the No. 1 secret vault, the Whispering Leaf needs to be exchanged for magic items of the same grade, and the Flame Tree Core needs to be exchanged for 3000 third-level magic stones or magic items of the same grade." They're all Level 3 materials, how are you going to get them?"

"My lord, I chose to exchange two pieces of third-level materials for these two. I would also like to exchange another copy of the Sage's bones and the Asker's knot. "Su Ze didn't get many magic materials in the battle to capture the tower, but the 5 materials from Andrew, all of them were good third-level materials, in addition to the Blood Sword Grass, there were still four pieces, he didn't mind exchanging them all, after all, Su Ze couldn't use them.

The bearded man of the finance department opened his eyes and looked at Su Ze when he heard this, the materials he wanted to exchange just now were not all dark type, even the bones of the sage of the light system were there, the Asker knot was the ash tree knot, which was a dark magic material, the whispering leaf was a neutral material, and the flame core was a partial fire system. It seemed that Su Ze was not going to cast a simple magic, he looked at Su Ze for a while before saying, "Except for the bones of the Sage who can't be exchanged in the No. 3 secret vault, there are all the others, do you want to change them all?"

No. 3 secret vault? Su Ze was stunned, isn't it the secret vault of the light department, the relationship between the dark department and the light department is not good, not to mention that he also killed their student Andrew, I am afraid it is not so easy to change things from there. Then he said, "Yes!"

The bearded administrator looked at him with astonishment, his hands moving, and asked, "What are you going to exchange it for?"

"Dead human bones, unicorn horns, wind thunder eagle feathers, and light attribute magic crystals!" Su Ze said.

The bearded magician took out a magic crystal and rubbed it for a while, as if to verify the information of the materials. It was quickly verified, and he wrote a receipt and said, "It is the number of those materials, and he will collect it for you after you give the receipt to the vault guard." Remember to give him the documents you are going to submit at the same time. ”

"Okay, thank you!"

Then he rushed to the secret vault, entered the mage tower as usual, and walked through the secluded and terrifying staircase and laneway, fortunately, Su Ze had experience and was not very afraid, he learned well this time, and as soon as he entered, he began to call out to the guards inside, no longer like a fool to bear the oppression of the forbidden demon realm and move forward.

The strange thing is that this time it was not the old man named Laurie who appeared, but a guard wrapped in a mage's robe, Su Ze took out four materials, and at the same time handed over the list and said respectfully: "This is the receipt and the materials I exchanged, please find out!"

The guard nodded, silently took the list, and checked that the materials were the same as the four documents written on the receipt, before turning and walking into the darkness where even an oil lamp could not be lit.

Without any instructions, Su Ze stayed quietly in place, and after a short time, when the guards reappeared, Su Ze saw four wooden boxes suspended beside him, and then flew towards him.

(I'll go, when did the sixth-level magicians in the academy start to be so worthless, it's too wasteful to use them to guard the secret vault!)

Purely interfering with objects with mental power is the patent of magicians who have reached the upper limit of spiritual power of 1000 points, and there are two obsidian walls here, and the only one who can control objects with spiritual power out of the body is a sixth-level magician.

Su Ze complained silently in his heart, but he hurriedly put the four boxes into the storage ring on his hand.

The Night Emissary had five copies of the materials in hand, and there were still eight copies left plus one copy of the Fire Monarch's bloodline.

......

After returning to the dormitory to check that the four materials were correct, he also went to the library to check how they were preserved, and the old Cole smiled and said that the wooden box that came with it was already the most secure means of preservation, and there was no need to use other means.

But since he had come here, Su Ze had an idea, and when he thought of something, he asked, "Cole, do you know how the Lonely Wood is refined?"

"How did you come up with this question? Could it be that you've found a 'Bloody Gladiatorial Arena' haha!" Cole teased.

(That's right!)

Su Ze said secretly, but he said: "I want to too, it's just because I encountered it in the last battle to capture the tower and almost died there, so I want to know about this killing weapon." ”

Cole showed an expression that was the same, scratched the gray withered hair and said, "The level of secrecy of this thing is quite high, and ordinary people really can't check it." But old man, I, hehe, I've been here for many years, and I've seen it before. ”

He glanced at Su Ze, who was full of anticipation, and warned with a smile: "Okay, satisfy your curiosity." But you are only allowed to look at it here, and you are not allowed to take it away!

Where would Su Ze say a word at this time? Hurriedly nodded and reassured.

Cole then shook the bell on the side and called a little elf to fetch the book. Soon Su Ze sat under the counter and began to flip through the thick "The Secret of Revitalizing Magical Plants", the palm-thick classic Su Ze could only open the "Lonely Wood" chapter, obviously Cole did it, Su Ze didn't care, he just wanted to know how to refine the Lonely Wood, and began to store the new knowledge in the calculation runes.

When Su Ze finished reading and raised his head again, he found that Cole was gone, so he had no choice but to shake the bell, and when the elf came, he pointed to the book, and then pointed to it, and watched the elf take the book to the huge bookshelf square below before leaving.

(The most important thing is to erase its sanity?) It seems that there is no chance before level six.) Fortunately, I found a way to cultivate it without flesh and blood, otherwise I really don't know what to do. ）

It is recorded in the classics that magic plants are different from ordinary plants in that they are activated, and they have the instinct of animals and can actively hunt for food and grow. In order to refine them into magical creations, except for the deactivation of the solitary wood, the rest of the steps are not much different from refining ordinary magical creations. There are also plant-based spiritual practices in Kyushu, so in Su Ze's view, deactivation is actually no different from erasing its spirituality. And the difficulty of erasing the spiritual difficulty of a magical creature is similar to that of a magician who kills people with pure mental power, and it is at least level six to have this kind of strength.

(However, in addition to recording the study of the magic array and the cultivation formation, didn't that jade slip also record a beast control technique later?)

In addition to the flying sword and magic robe that Su Ze received in the secret vault last time, there was also a piece of jade slip. Originally, he was full of anticipation and hoped to get a new sword technique, although he already had two advanced sword skills, but what sword cultivator would think that the sword skills were too strong? The result made him very disappointed, and it was the posthumous work of a disciple of the Imperial Beast Sect called Qianyu Dao in the north of Yongzhou.

In addition to being a beast master in the late stage of foundation building, this disciple named Ding Liangji is also a formation mage, which records his life's experience of the formation path and his experience after being exiled to the other world, as well as the study of the magic array of the main plane.

This kind of research comparing the differences between the two realms is very precious, but it is a pity that Bai Bi is covered with dust and falls into the hands of Su Ze. He just glanced at it and threw it into the cold room, tossing it into the corner of the storage ring and leaving it alone. Now I found that the solitary wood was actually not much different from the demon cultivation of the plant department, and it seemed that it could be tried to be subdued and cultivated as a spirit beast under the seat, so Su Ze's mind suddenly came alive, and he found it out from the corner, and then carefully studied this Dao fruit-level (Yuan Infancy) exercise called "Soul Carving Beast Technique", trying to find a way to subdue the solitary wood.

According to the record of "Carving Soul and Beast Technique", the foundation of the sect of Thousand Feather Dao lies in the union of demons. Unlike the general Imperial Beast Sect that directly uses demon beasts as slaves and resources consumed for promotion, the approach taken by Thousand Feather Dao is relatively mild, more similar to a companion contract. They do not subdue the monsters, but adopt the method of equal coexistence and mutual symbiosis to control the monsters, and the relationship between the two is more similar to that of partners. Therefore, this sect is very close to the demon cultivation forces, and it is hostile to its peers!

Su Ze didn't care about this kind of sectarian dispute, as long as he could control the lonely wood. It's just that the problem now is that there are very few botanical devotionals in Kyushu, and almost none exist. Even the Thousand Feather Dao Li Sect has never had a record of the imperial envoy's spiritual cultivation, and theoretically the exercises are all the same for spiritual demon beasts, but no one knows what the actual effect is.

(But it doesn't hurt to give it a try!)

Su Ze didn't dare to use the wooden pendant in the academy, and the fluctuations of the storage ring and the space magic weapon were very different. Only after he understood the methods of high-level magicians, he no longer dared to take it lightly, and he could only walk on thin ice!

After thinking about it, Su Ze put away the jade slip, took out the damaged spirit-level flying sword and played with it for a while before taking it back into the ring, thinking that if there was a chance, he would repair it, and if he didn't have a chance, he wouldn't force it, anyway, there was no shortage of flying swords.

Then he took out the magic crystal that stored the "Wasteland Swordsmanship" and began to figure it out, the current Cole's strength is too weak to feed Su Ze, but fortunately, the calculation method is getting stronger and stronger, and the effect of the practice in his mind is not bad.

"However, it is still necessary to improve Cole's strength as soon as possible!"
