When Gilbert heard Leylin's words, he was stunned for a moment, but he burst out laughing.

"I'll accept your gift!"

"Thank you, teacher!" Lei Lin 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 looked down and thought for a moment.

"Aren't you accumulating contribution points to buy the Construct's Activation Scroll? I'll exchange it with you directly, and a scroll with a fourth-level witchcraft sealed can almost match these things!"

Gilbert reached out and stroked the table, and the many bloodline items disappeared, but a gray scroll covered with ancient patterns appeared.

"Thank you, teacher!" Lei Lin took the scroll and thanked him again, this time with a little more sincerity.

"And ......" Gilbert smiled as he looked at Leylin's ring.

Lei Lin touched his head, showing an embarrassed expression, knowing that the other party had discovered what he had hidden in the spatial ring.

......

At night, Leylin lay on the bed, looking at the scroll in his hand, and a look of satisfaction appeared on his face.

"Those things are really similar in exchange for this fourth-level scroll, and I didn't suffer any losses!"

Then he looked at the ring on his hand and collapsed on the bed, seemingly falling into a deep sleep as if he had quickly fallen into a deep sleep.

But in fact, he was sneering in his heart.

What Gilbert discovered was actually what he deliberately let Gilbert discover.

In the ring on his hand, there was only a bloodline spar and a few ancient remains, and it was precisely because of the small number that Gilbert did not look very well and acquiesced to Leylin's private collection.

But in fact, what he handed over today is not even half of the real harvest!

Not to mention the finger bones left behind by the fifth-level Ancient Snake Girl.

The temptation of this kind of thing is so great that even Leylin is reluctant to take it out, otherwise, Gilbert's level here will be very difficult.

When the time comes, whatever happens. None of the situations he wants to see.

After all, Gilbert was pretty good to him, and he didn't want to fall out with his teacher and the Ouroboros.

Interests are often the biggest factor that leads to division, and Lei Lin doesn't want to use his finger bones to test the relationship between master and apprentice. Just avoid it, it's good for everyone.

Yes, the real gains, including the snake woman's phalanx and the like, are not on Thunderlin at all!

Therefore. No matter how rigorous Gilbert's detection is, it is completely useless!

"However, although the process was thrilling this time, I finally got what I wanted, and the other gains were also very good......" Lei Lin thought as he lay on the bed, and soon fell into a real slumber.

The speed of the Black Scale was very fast, and it took Leylin and them more than a month to reach Sin City from the area where the Ouroboros Ring was located, but it only took a dozen days to return.

After returning to the headquarters, Lei Lin gathered with his teacher and a few seniors for a while, citing the fact that the wizard tower in the territory was about to be completed. Back to Black Castle.

"Greetings, my lord!" Pike stood in front of the black wizard tower, saluting respectfully to Leylin, his voice still as old as ever, and a strange sense of confusion in line with his young face.

"How's my wizard's tower going?"

Lei Lin stepped forward and stroked the black tower, looking at the delicate runes on it, as well as the powerful energy fluctuations faintly emanating, 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 are activated!

Pike's answer was very satisfying to Leylin. He was also very conscientious in his work, and the last time he was asked to do a very good job, he succeeded in delivering the letter to the Archduke Gilbert, saving Leylin from his fate.

"Good!" Leylin nodded.

"Send Sluby to my lab another day. It's been a long time since I've taught him anything new!"

Of course, he knew that Pike was old and unmotivated, and all his hopes were placed on his grandson, and no reward could be compared to the importance of Sluby.

"I thank the master in his place!"

Sure enough, after hearing Leylin's words, a hint of excitement appeared on Pike's face. The waist is bent at 90 degrees.

"When I came back this time, I had already exchanged the Activation Scroll from the teacher, and I ordered to go down and prepare to start work, I will complete my wizard tower immediately!"

Lei Lin gave the order indifferently.

"Your will will be executed!" Pike replied, all the construction preparations were completed, and the other core materials were also ready, just waiting for Leylin to return and lead the way.

Wandering through the interior of his own wizard's tower, Leylin carefully observes every place.

The interior of the Wizard's Tower is very large, and Thunderlin is all built to the highest standards, and the facilities inside are very complete, and they look very beautiful and luxurious.

Lei Lin looked at 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.

"How's the scanning?" While looking around, Lei Lin didn't forget to let the chip fully record the layout and witchcraft array scans he saw, and then check them.

"The main body of the Wizard Tower building has been scanned 67.8%, the defense of the Wizard Array is running well, and the area can be optimized: 2 places!" the chip faithfully reported.

Since the architectural drawings were originally made by Lei Lin himself, using the perfect deduction of the chip, the layout of the entire wizard tower was perfect, almost to the point of impeccable.

The remaining area that can be optimized is only a small problem due to 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, and Lei Lin has long been prepared for this.

"Everything else is okay, but the previous ecological park can be changed to add the ancient environmental data I collected in the Quicksand Castle!"

Leylin touched his chin.

Now the wizard tower is not completed, while it can be modified now, if you wait until the defensive witch array is activated, especially after awakening the tower spirit, it really can't be changed.

"Chip! According to what I just said, design a rectification drawing!"

This kind of tedious thing, Lei Lin has always liked to leave it to the chip to do, and he can grasp the general direction.

"The task is established, the original drawings are called out, the ancient environmental parameters are simulated and transferred, and the design drawings are ...... formed"

The chip sped fast, and within a few minutes, a new drawing was projected in front of Leylin.

"Hmm! make the most of the original resources and settings, just need to add a few more things and the witch circle!

Lei Lin looked at it several times and expressed satisfaction with the design drawings of the chip.

He now has a large number of subordinates, as well as a large number of stone slaves, and the rectification is only a little explained, and several groups of people take turns to start work day and night, and it will be completely completed after ten days.

Lei Lin stood next to the negative energy pool at the bottom, looking at the intricate witchcraft patterns on the ground, as well as the light emitted by many precious materials such as adamantite gold and mythril, the expression on his face was calm and calm.

"The overall witch array simulation of the wizard tower has been completed, with 341 rehearsals and 0 failures!"

In the depths of Leylin's eyes, the blue light of the chip flashed.

"Here we go!"

Thunderlin exhaled lightly and placed a concentrated energy crystal that emitted a huge amount of light and heat, like a small sun, into the groove in the center of the witch circle.

Buzzing!

The entire witch array immediately began to tremble, and circles of talismans appeared in the air, and a trace of light flowed on the witch array.

"Activate!" Lei Lin's spiritual power spread out, connecting with the Witch Array.

The moment the spiritual power came into contact with the Witch Array, Lei Lin felt as if he had opened a valve, and many energy particles were frantically absorbed by the Witch Array, and then merged into the negative energy pool through complex transformation channels.

And just outside the Wizard's Tower, Pike, Gübler, Sluby and other Leylin's men all gathered, all with light in their eyes, watching this scene.

The huge elemental wave seemed to form a whirlpool, sucked up by the black wizard tower.

One after another of the witchcraft runes lit up from the tower, with terrifying but steady fluctuations, firmly connected together.

At this time, there was only one person in the wizard tower, and he quickly came to the top of the wizard tower, looking almost exactly the same as before, but giving people a completely different feeling of the witch array and storage pool.

"Next up is the pool of positive energy!"

An identical high-energy crystal was pressed into a groove by Leylin, and the same activation technique emerged from Leylin's hand and sank into the walls on all sides.

Rumble!

Above the wizard tower, the huge wave of elements almost condensed into substance, and the energy particles of various colors were brilliant, and soon settled, forming two rainbows, one bright and one dark.

Then, the bright rainbow was absorbed by the spire, but the dark golden rainbow sank into the ground.

Buzzing!

The pool of positive and negative energy continued to hum, and the elemental liquid inside was more and more full, and finally reached the halfway point.

Two star-like rays of light emerged from the spire and the ground respectively, and continued to spread towards the tower.

One by one, the symbols lit up and finally converged in the middle of the Wizard's Tower.

"The Wizard Tower's Wizard Circle is all activated!

The prompt of the chip sounded, and at this time, Lei Lin was standing at the intersection of positive and negative energy, and in his hand, a scroll with a simple appearance and a strange pattern appeared.

"Level 4 Sorcery - Constructor Activation Scroll!"

"Also, chips, prepare sub-agents!"

Lei Lin tore open the gray scroll, the light flashed, and suddenly, a terrifying suction force was transmitted from the scroll, and the vaporized spiritual power in his sea of consciousness was consumed in large quantities, and it was not until it was about to be exhausted. (To be continued.) )
