Lu Zhiyu stood up, his hands were knitted in the air, although he couldn't see anything with the naked eye, but in the eyes of the wizards present, he immediately saw that the spiritual power sensed Lu Zhiyu's hands, and the spiritual power continued to shuttle, forming an extremely complex spiritual force field structure.

The use of the spiritual force field structure is not only used to stabilize the spiritual structure in meditation, but also used by third-level wizards to build their own spiritual force force field barrier, and the force field structure in Lu Zhiyu's hand is complex and dazzling, and only a trace of spiritual power like silk threads is assembled into an extremely complex geometric three-dimensional figure.

This structure continued to rotate and shape in Lu Zhiyu's hands, and then they felt that Lu Zhiyu was hooked into the magic net and extracted essentia, but it was not integrated into their own spiritual power.

Immediately, I saw a silver water droplet gushing out of the void little by little, bound by the spiritual power structure of the land fish, constantly compressing towards the center, and finally condensing into a silver-white crystal the size of a grain of rice.

Pol looked at Lu Zhiyu with his mouth wide open: "Magic? The magic has been realized! ”

Lu Zhiyu took a look, this was a scale essenca, only a crystalline the size of a grain of rice, but it was something that Pol could only get after a month of meditation, and the other wizards didn't know how long it would take.

Lu Zhiyu handed it to Pol: "Integrate a trace of spiritual power into it!" ”

Pol did what Lu Zhiyu said without the slightest doubt, and the high concentration of essentia crystals immediately made Pol's spiritual power tumble like boiling water, and immediately saw that part of the spiritual power immediately underwent earth-shaking changes, resulting in qualitative changes, but because the essentia crystals were too small, it was not enough to urge all his spiritual power and consciousness to resonate at the same time and merge into one.

Lu Zhiyu nodded: "Sure enough!" ”

"The change of spiritual power needs to be driven by the environment!"

Pol felt the changes in some of his spiritual power, if he could have enough essentia crystals, he could completely fuse his spiritual power and consciousness together, and the final transformation would occur, but the essentia that each person extracted every day was limited, and Pol felt that it was not easy for him to condense enough crystals.

"So if we want to complete the activation and transformation of spiritual power, we still need a large enough magic crystal, right? Mentor! ”

Lu Zhiyu nodded, they didn't want to absorb this magic crystal, but they needed this magic crystal to help them create an environment that promoted the qualitative change of spiritual power, so this magic crystal can be reused, although it will cause consumption after each use, it is not large.

Lu Zhiyu said: "I will give you the way to condense this spar, you can work together to make it, but this spar is no longer an ordinary magic power, but a stone that is embodied by magic power into the present world, and the name of the magic crystallization you said before is not very accurate." ”

Lu Zhiyu pondered for a moment, this kind of stone can make spiritual power, from an illusory existence, to a qualitative change, interfering with reality into reality, and Lu Zhiyu has heard of an existence before, Lu Zhiyu said with a smile: "Then call it - the Sage's Stone." ”

Lu Zhiyu held a spar the size of a grain of rice, and everyone seemed to see the real sage preaching to them, Lu Zhiyu held the Philosopher's Stone in both hands, and the structure of his spiritual power was constantly changing, explaining to them the steps of making the Philosopher's Stone.

For Lu Zhiyu, this is nothing too complicated or magical, and it is worthless to put it bluntly, but for others, this philosopher's stone is simply the door to a new world, such a stone can change the nature of their spiritual power, so that the brain can be truly deified, step into the fourth-level deification wizard, and really begin to involve the edge of mythology, and you can explore step by step to the point of becoming a seventh-level mythical creature.

The appearance of the Philosopher's Stone also solved the only obstacle to their next step, especially for Pol, it was a real relief.

In the following time, Pol and the wizard team began to research and develop the Philosopher's Stone, and their spiritual strength and control were not able to easily construct such a large and complex spiritual force field in their hands like a land fish.

They then came up with another method, dividing a part of the area in the wizard tower, and depicting the guidance array, just like the land fish first used the dimensional gate, depicting complex structural patterns to guide the spiritual power structure, positioning and fixing.

Lu Zhiyu stood aside, instructing, and saw a large guidance array, covering the entire part of the hall, in Lu Zhiyu's hand, the palm-sized spiritual power structure, analysis and dissolution, even spread over the hall of dozens of meters, the ground is densely packed with carved guidance arrays, this belongs to the top hall of Lu Zhiyu, and in the future, because of the appearance of the philosopher's stone manufacturing method and the guidance stone, it will become a forbidden place for the entire wizard tower, without the recognition of Lu Zhiyu or the tower's acting tower master, no one can enter here.

The Sphinx Piroth, who was originally guarding the top floor, was assigned by Lu Zhiyu to take care of the library, the Tower Library, which is one of the most important core areas inside the tower, and it is also a place that Lu Zhiyu attaches great importance to, and the Sphinx was also transformed into his own family by Lu Zhiyu.

It can remember all the knowledge in the library, and it will also save and update, it is in charge of the knowledge of the Wizard Tower, the exchange of points, any new knowledge of the Wizard Tower, will be exchanged for points in his place, and at the same time, the wizard tower with the wizard badge on the outside will also use the wizard badge to communicate with it, exchange it, or exchange materials, and then it will communicate with the Wind Raven postman for mailing.

Therefore, its existence actually represents the library, and when it leaves the next generation of sphinxes to die, it will ascend to the kingdom of God and bring all the knowledge that Lu Zhiyu wants, which will be passed down from generation to generation, and will be an important source of knowledge and information for Lu Zhiyu.

For wizards, they just think that this intelligent beast is very special, very intelligent, and it seems like a huge library, prophet, who knows all the knowledge and information they want.

In the past few days, Lu Zhiyu has been constantly updating its huge library knowledge from this sphinx to its own wisdom and vice brain, and over the past few decades, all kinds of witchcraft of wizards have also undergone strong changes and various updates, especially in terms of bloodline witchcraft, although most of them have no effect on Lu Zhiyu, but the whimsy of some wizards or apprentices also has a great opening up effect on the vision of Lu Yu.

Only here can Lu Zhiyu feel the real reward that he brought to himself by founding the Wizard Tower and teaching witchcraft, and Lu Zhiyu believes that as the development of wizards continues to advance, this reward will be more and more, and it will be bigger and bigger.

"Let's get started!"

Lu Zhiyu paid attention to his students, and very cautiously began to make the Philosopher's Stone, the seven wizards stood on the Philosopher's Stone refining array, and immediately began to form a spiritual force field through the combination of spiritual power, extracting magic power from the magic net, and immediately saw a silver-white grain of rice in the center emerge, constantly flickering, in a way that is indecipherable to the naked eye, it is growing, and when everyone's mental power fails, it has not increased much.

Pol held the small crystal in his hand a little exhausted: "It seems that it will take a few years to complete, but there is no hurry, we still have time to wait." ”

Pol is nearly fifty years old this year, but he has fused the spell-casting organs of the two-headed eagle demon, has active cells, and has a lifespan that is higher than that of ordinary people, and can reach about two hundred years, so there is no need to be in a hurry.

Lu Zhiyu walked over and slapped his face: "Very good, you have taken another step towards the path of wizards, Pol, you have done a very good job over the years, creating the path of bloodline wizards, and I am also very pleased, I hope that the next time I return, you are already a fourth-level wizard, and you have brought more different changes to the development of wizards." ”

Pol and the other students looked at Lu Zhiyu together: "Mentor Anthony, are you leaving again?" ”

Lu Zhiyu shook his head: "It will be a few days, but it's soon, you see if you have any questions or some ideas, while I'm here, bring them up with me, the next time we meet, it will take a long time!" ”
