"Liu Li, go to warehouse three, the fourth row of shelves, I remember there is a large piece of Mithril there, help me bring it...... Oh, by the way, there should be a piece of glitter silver next to it, bring it with you. Landoria held the carving knife in her hand and said without looking back: "After taking it back, use the synthesis furnace on the left to fuse it in a ratio of seven to three, and then draw it into filaments, the thickness of which is ...... Well, number two, let's do ten meters out first. ”

Liu Li, who was reduced to a porter, was also in charge of the work of the hand, and was very busy for a while. There was no one but him who could help with these things, and only Wells, who was far away in the west, had free access to the warehouse of the Landoria Mage Tower.

With her wings folded, she stood aside, looking at the busy pair of masters and apprentices, and it had to admit that Landolia had the strength she had now, thanks not only to the powerful talent inherited from Crosis, but also to her own efforts. At least Sister Bailong hadn't heard that her brother had a talent for tectonics, but she was good at sabotage. Tsuwi still remembers that his Dragon City, which was once located in the center of the "Celestial Realm", that is, the predecessor of the "Sanctuary: City of Glory" spell, was inadvertently demolished by Croxith.

"Hmm, sixth-order black magic crystal...... Wait, Liu Li, how many of your elemental crystals are left, are there enough for ten, if you have enough, bring them. "According to Landolia's original plan, this simple mage tower was to be brought back when she had the opportunity to return to the Necromantic Realm. But now, the Vice Dean intends to keep it for his students, so it is naturally impossible to use the black magic crystal as the main material for building the elemental pool.

At this time, although Liu Li didn't know Landolia's plans, since the teacher spoke, no matter how precious the elemental crystals were, he didn't think of refusing. Landolia once commented on Liu Li's condensed elemental crystals, believing that the reason why they were comparable to sixth-order magic crystals was not only because of the total amount of elements contained in them.

The sixth-order magic crystal already has the property of absorbing free elements, as long as the elements inside are not consumed all at once, as long as they are placed in a suitable environment, they can be slowly recovered. Liu Li's condensed elemental crystals also have this property, but because they contain the five-color elements, it is a little troublesome to recover - it is not easy to find a place in the natural environment where the five-color elements are balanced and safe with each other.

In fact, those elemental crystals, although there are not a few that have been used, but the real consumption is only seven. In addition to the one given to the Ancient Tree of Life, and the two that were completely destroyed when the Circle of Rejection was built in the Dark Cave, four crystallized into the weapons of Squirrel and Lynn. The same used in the Dark Cavern, including the construction of the absorption circle, and the final use by Landolia and Wells, plus the one that Odin lent to Ankka to deal with Swallowing Cloud this time, have all been recovered.

There are as many as twenty remaining elemental crystals in Liu Li, but it is just necessary to build an elemental pool, and not all crystals are suitable for use as the main material. The five crystals used in the Dark Cavern for the circle nodes, plus the one consumed when repairing the circle, are more abundant in the elements, but most of them are "chaotic elements", which are obviously unusable. The three used by Wells, Landolia, and Ankka are the opposite, and the elements in them have been consumed a lot, and they have not yet recovered to their original state. Removing the one that was one size smaller when it was first condensed, and which was injected into the "Life Rune" by the ancient tree, there are exactly ten pieces left that are really suitable as the main material of the elemental pool.

Cuiwa watched blankly as Liu Li took out the elemental crystals from the storage space, and then carefully selected those that were suitable as the main materials of the elemental pool, and gradually became numb from amazement. If you talk about the understanding of these crystals, I am afraid that there is no creature in this world that will surpass a few primeval dragon kings, even the white dragon sister, who had seen this kind of thing in the time when she was just born, did not expect that as many as twenty would appear in front of her at a time.

Normal sixth-order magic crystals would not attract the attention of a super-level like Cuiwa at all, but these crystals of Liu Li were obviously not among them, they were not just ordinary elemental crystals, but had a trace of the aura that belonged to "him". Previously, in the spatial rift, when Liu Li lent a crystal to Anka, it attracted Cuiwa's attention, but the situation was urgent at that time, and Sister Bailong didn't have time to ask more. Now that Liu Li took out so much at once, Cuiwa knew that it was no accident that Liu Li could get this kind of thing.

"Xiao Liu Li, where did you find these elemental crystals?"

Liu Li was stunned by the inquiry from the "Psychic Connection", but quickly recovered, and answered Cuiwa's question while handing the elemental crystals to Landolia.

"Heh, I have to say, your luck is really good. Cuiwa couldn't cry or laugh, how could the super-level white dragon not think that these crystals were actually the by-products of Liu Li's resurrection, "The rest of them are spared, these things are even more precious than most super-level materials in some ways, your teacher used them to build an elemental pool, it is completely overkill to cast them into weapons like you did before." ”

Cuiwa did not explain the effect of these elemental crystallizations to Liu Li in more detail, and Sister Bailong learned to be smart this time, and after realizing that there might be some secrets that could not be mentioned, she kept silent, which made Liu Li somewhat disappointed.

In the busyness of Landolia and Liu Li, time flew by, and when the carriage was new again, a whole day had passed. The reborn carriage had consumed nearly half of Landolia's inventory, and it was impossible to count the amount of gold coins converted, and many rare materials were simply not available for money. However, the performance of the carriage is indeed worthy of these precious materials, and the increase in the amount of the caster sitting in it is at least fifty percent higher than before, and this is not counting the short but violent explosion that ignites the crystallization of all the elements.

"Whew, it's finally done. Landolia breathed a sigh of relief and gently wiped the beads of sweat from her forehead. She is very satisfied with her work, and she pursues the limits to bring out the performance of all materials to the extreme. Even Tsuiwa was amazed by the witch's whimsy, at least Sister Bailong had never thought of setting up a magic circle as a three-dimensional structure. "Liu Li, come here, imprint your spiritual power imprint here. ”

"Teacher, this ......" participated in the structure of the Simple Mage Tower throughout the whole process, how could Liu Li not guess what the meaning of Landolia's order represented—Landoria was going to give him the carriage, instead of just giving him a control authority as before.

"Don't talk nonsense, don't waste time. Seeing Liu Li's hesitation and overwhelmed appearance, Landolia said angrily: "For a spellcaster, the three things of the staff, the robe and the mage tower are the most important auxiliary tools, Will gave you a staff that can be used to the high level, and this exchange meeting has allowed you to get a good robe again, and it is no problem for me to give you a mage tower, right?"

"Yes...... But teacher, this is too precious. ”

"So you have to use it well, and if it breaks again, I'll have to charge for repairing it. ”

Landolia also had her plans in mind for making this decision. Ever since she learned of Cuiwa's identity, the vice dean had a trace of doubt in her heart, she didn't know what kind of virtue and ability she had, a talented student, who could be favored by super-level beings many times. This is of course a good thing, but it will also make the witch feel uneasy, if it is pure kindness, it is fine, if these super-level existences have a plot against Liu Li, they have to prepare early.

Although Landoria was still far away from the seventh order, thanks to her understanding of the black ancient runes, she also had the confidence to advance to the super rank. After being promoted to the sixth order, the vice dean could vaguely perceive the extraordinaryness of the elemental crystals condensed by Liu Li, and now he used a full ten coins for the creation of the carriage element pool, just to leave Liu Li a hole card to save his life. Landolia believed that even a super-level existence could not survive the explosion of destruction of the elemental pool.

"That'...... Thank you, Mr. Landot. Liu Li thanked him, and then couldn't wait to imprint his spiritual power into the core of the Simple Mage Tower. When the imprint and the core were integrated, Liu Li felt that there was a sense of blood connection between himself and this mage tower, and all the functions of this mage tower were also displayed in his mind.

"Wow! Five-color element amplification! Sixth-order defense array! There is actually a phase barrier...... What is this?" Liu Li looked up everything about the Mage Tower with ecstasy, until he saw a line of instructions, and a drop of cold sweat finally left on his forehead.

"Sixth Order...... Wizard Bombardment...... Array. ...... Teacher, are you making a mistake?"

Of course, Liu Li had heard of this kind of thing, the only remaining array in the Aode Continent was located in the center of the continent and belonged to the "Sky Tower" holy land, which was used to protect the iconic "Sky Tower", Liu Li didn't expect Landolia to load such a terrifying thing on a simple mage tower. It's not that this array is so troublesome to set up, it's just that the cost of this kind of thing used to defend and counterattack is too huge, in the previous casual conversation with Kayla, Liu Li had heard Bai Mao say that even if it is a super-level existence, it can only support the full stimulation of the single-line element array for about an hour when it is in perfect condition, but Landolia has loaded all the five-series element arrays on the carriage, and such a frenzied behavior may only be done by the terrifying "Black Hole Witch".

"Don't worry, look further down, there's something even more fun. "Landolia is also very proud, as a sixth-order mage specializing in black elements, it is not easy to carve a five-series array, and it is thanks to her three-dimensional array theory that it can be successfully erected.

"Elemental Burst System (Use with caution), what is this?" Liu Li continued to check, and finally found a line of small words in the corner, "And grading...... Tide, Storm, Annihilation...... Teacher, this is ...... Self-destruct system, right?"

"Ah, yes, but I like to call it - a spectacular firework. ”

Cuiwa lowered her head to the side, listening to the exchange between the master and apprentice, and forced herself to resist the roar that was about to blurt out. Sister Bailong admired Landolia so much at the moment, but she especially wanted to ask the witch: "You...... Isn't it a bad brain?"
