After hearing Leylin's words, Gilbert was taken aback for a moment, but laughed out loud.
"I will accept this gift from you!"
"Thank you teacher!" Leylin bowed gratefully.
"Well! Of course, I won't ask for your things in vain. After all, the ancient blood vulture eggs are still very precious!" Gilbert lowered his head and thought for a while.
"How about this! Aren't you accumulating contribution points to buy the Construct Revitalization Scroll? I exchanged it with you directly. A scroll sealed with Level 4 witchcraft can almost be worth these things!"
Gilbert reached out and stroked the table, and many bloodline items disappeared, but there was a gray scroll full of simple patterns.
"Thank you teacher!" Leylin took the scroll and thanked him again, this time with a little more sincerity.
"And..." Gilbert looked at Leylin's ring and smiled.
Leylin rubbed his head, showing an embarrassed expression, knowing that the other party had discovered what he had hidden in the interspatial ring.
…
At night, Leylin lay on the bed, looking at the scroll in his hand, with a look of satisfaction on his face.
"Exchanging those things for this fourth-level scroll is indeed the same, and I didn't suffer much!"
Afterwards, he looked at the ring on his hand again, and fell on the bed, seemingly falling into a deep sleep very quickly.
But in fact, he was sneering in his heart.
What Gilbert discovered was actually what he deliberately let Gilbert discover.
In the ring in his hand, there was only one blood spar and a few pieces of ancient remains stored. It was precisely because of the small number that Gilbert didn't like it very much, so he acquiesced to Leylin's private collection.
But in fact, what he handed over today was not even 10% of what he had actually gained!
Not to mention the finger bones left by the fifth-level ancient snake girl.
The temptation of this kind of thing is so great that even Leylin is unwilling to take it out, otherwise, Gilbert's level here will be very difficult to pass.
No matter what happens at that time, it is not the situation he wants to see.
After all, Gilbert treated him pretty well, and he didn't want to turn against his teacher and the Ring of Ouroboros.
Interests are often the biggest factor leading to splits. Leylin didn't want to use his finger bones to test the relationship between master and apprentice, so he simply avoided it. This is good for everyone.
That's right, the real rewards, including the finger bones of the snake girl, were not on Leylin at all!
Therefore, no matter how rigorous Gilbert's detection is, it is completely useless!
"However, although the process this time was thrilling, I finally got what I wanted, and the other gains were also very good..." Leylin lay on the bed thinking, and soon fell into a real deep sleep.
The speed of the Black Scale was very fast. It took Leylin and the others more than a month to get from the area where the Ouroboros Ring was located to Sin City, but the return journey only took more than ten days.
After returning to the headquarters, Leylin got together with his teacher and a few seniors for a while, and returned to Black Castle on the grounds that the wizard tower in the territory was about to be completed.
"Congratulations, my lord!" Pike stood in front of the black wizard's tower, saluted Leylin respectfully, his voice was still old as before, and matched with his young face, there was a strange feeling of confusion.
"How is my wizard tower going?"
Leylin stepped forward, caressing the black body of the tower, seeing the exquisite runes on it, and the powerful energy fluctuations emanating faintly, a smile appeared on his face.
"The overall structure of the wizard tower has been completed, only a few cores and the most important tower spirit activation are left! These are all waiting for the master to come and complete them!"
Pike's answer made Leylin very satisfied. He was also very serious about his work, and he did a good job in what he told him last time. He successfully delivered the letter to Grand Duke Gilbert, saving Leylin from his bad luck.
"Very good!" Leylin nodded.
"Send Sruby to my lab some other day, and I haven't taught him anything new for a long time!"
Of course he knew that Pike was old and unmotivated, and all his hopes were placed on his grandson, and no reward could compare to the importance he attached to Sruby.
"I thank the master on his behalf!"
Sure enough, after hearing Leylin's words, Pike faintly showed a hint of excitement, and his waist was bent at ninety degrees.
"When I came back this time, I had already exchanged the activation scroll from the teacher. I ordered to go down and get ready to start work. I want to finish my wizard tower immediately!"
Leylin calmly gave the order.
"Your will will be carried out!" Pike replied, all construction preparations have been completed, and several other core materials have also been prepared, and they are waiting for Leylin to come back and take the lead.
Walking in his wizard tower, Leylin carefully observed every place.
The interior space of the wizard tower is very large, and Leylin has built everything according to the highest standards. The facilities inside are very complete, and it looks very exquisite and luxurious.
Leylin looked layer after layer, especially the two positive and negative energy pools, as well as the laboratory, the bondage room, the ecological garden and other places.
"Chip! How's the scan going?" While he was looking around, Leylin didn't forget to let the chip fully record the layout he saw and scan the witchcraft circle before checking.
"67.8% of the main building of the wizard tower has been scanned, and the defensive wizard array is running well, and the area can be optimized: 2 places!" The chip faithfully responded.
Since the architectural drawings were originally made by Leylin himself, using the perfect deduction of the chip, the layout of the entire wizard tower is perfect, almost impeccable.
The remaining areas that can be optimized are just small problems caused by improper construction and other reasons. No matter how perfect the plan is, as long as it is manipulated and mastered by people, there will always be accidents. Leylin has long been prepared for this.
"Everything else is fine, that is, the previous ecological park can be changed to include the ancient environmental data I collected in Quicksand Castle!"
Leylin touched his chin.
Now that the wizard tower is not yet completed, it can be modified while it is still there. If the defensive wizard formation is activated, especially after the tower spirit is awakened, it will really be impossible to change it.
"Chip! According to what I just said, design a rectification blueprint!"
Leylin always likes to leave this kind of tedious work to the chip, and he can just grasp the general direction.
"The task is established, the original blueprint is called out! The ancient environment parameters are simulated and called in, and the design drawing begins to form..."
The chip was running rapidly, and within a few minutes, a new blueprint was projected in front of Leylin.
"Well! The original resources and settings are used to the greatest extent, just need to add a few more things and the witch array! That's it!"
Leylin read it several times and was satisfied with the design of the chip.
He has many subordinates now, and there are also a large number of stone slaves. The rectification is only a little explained. Several groups of people take turns to work day and night, and it will be completely completed after more than ten days.
Leylin stood next to the negative energy pool on the bottom floor, looking at the complex patterns of witchcraft on the ground, as well as the rays of light emanating from precious materials such as fine gold and mithril. .
"The simulation of the wizard tower's overall wizard array is complete, with 341 rehearsals, and the number of failures: 0!"
In the depths of Leylin's eyes, the blue light of the chip flashed past.
"here we go!"
Leylin exhaled lightly, and put a condensed energy spar emitting huge light and heat, like a small sun, into the groove in the center of the witch formation.
Buzz!
The entire witch formation immediately began to vibrate, circle after circle of runes emerged out of thin air, and traces of light circulated on the witch formation.
"Activate!" Leylin's spiritual power spread out and connected with the witch formation.
The moment his mental power touched the Wuzhen, Leylin felt as if he had opened a valve. Numerous energy particles were frantically absorbed by the Wuzhen, and flowed into the negative energy pool through complicated transformation channels.
And just outside the wizard's tower, Pike, Gubler, Sruby and other Leylin's subordinates all gathered, their eyes were shining, watching this scene.
A huge wave of elements seemed to form a vortex, sucked by the black wizard tower.
One after another, the witchcraft runes lit up from the tower, with terrifying but steady fluctuations, firmly connected in series.
At this moment, Leylin was the only one in the wizard tower. He quickly came to the top of the wizard tower. He saw the wizard formation and storage pool, which looked almost identical in shape to before, but had a completely different feel.
"Next is the positive energy pool!"
The same high-energy crystal was pushed into the groove by Leylin, and the same activation formula emerged from Leylin's hand and sank into the walls on all sides.
boom!
Above the wizard's tower, the huge wave of elements almost condensed into substance, and the energy particles of various colors were radiant, and soon settled down, forming two rainbows, one bright and one dark.
Afterwards, the bright rainbow was absorbed by the spire, while the dark golden rainbow sank into the ground.
Buzz!
The positive and negative energy pool hummed continuously, and the elemental liquid inside became more and more full, until it reached halfway.
Two stars-like rays of light emerged from the top of the tower and from the ground respectively, and then continued to spread towards the tower.
Numerous symbols lit up one by one, and finally gathered in the middle of the wizard tower.
"All wizard tower wizard formations are activated! Currently running well!"
The reminder of the chip sounded, and at this moment, Leylin was standing at the intersection of positive and negative energies. In his hand, a scroll with a simple appearance and a strange pattern emerged.
"Level 4 Witchcraft—Construct Activation Scroll!"
"Also, chip, prepare sub-agents!"
Leylin tore open the gray scroll, and the light flashed. Immediately, a terrifying suction force was transmitted from the scroll. The vaporized spiritual power in his sea of consciousness was consumed in a large amount, and it barely stopped until it was almost exhausted.
