After hearing Raylin's words, Gilbert was stunned for a moment, but burst into laughter.

"I'll accept your gift!"

"Thank you, teacher!" Lei Lin bowed with gratitude.

"Well! Of course, I won't ask for your stuff for nothing. After all, the ancient blood eagle eggs are still very precious!" Gilbert lowered his head and thought for a moment.

"This is how you are accumulating contribution points to buy the construct activation technique scroll? I'll exchange it with you directly. A scroll with level 4 witchcraft sealed is almost worthy of these things!"

Gilbert reached out to touch the table, and many blood objects disappeared, but there was a gray scroll covered with quaint patterns.

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

"And..." Gilbert looked at Rayling's ring and smiled.

Lei Lin touched his head and showed a embarrassed expression, knowing that the other party had discovered what he had hidden in the space ring.

...

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

"Those things are about the same when replaced with this level 4 scroll, and I didn't suffer any loss!"

Then, he looked at the ring on his hand and fell on the bed, and seemed to soon fall into a deep sleep.

But in fact, he was sneering in his heart.

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

In the ring on his hand, only a bloodline crystal and a few ancient remains were stored. It was precisely because of the small number that Gilbert didn't like it, so he acquiesced to Lei Lin's private possession.

But in fact, what he handed over today is less than 10,000 yuan that he really 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 Lelin is unwilling to take it out, otherwise Gilbert's level here would be difficult.

No matter what happens, it will not be the situation he is willing to see.

After all, Gilbert treats him well, and he doesn't want to turn against his teacher and the Weaver Snake.

Interests are often the biggest factor leading to division. Lei Lin doesn't want to use his finger bones to test the relationship between master and apprentice, so he simply avoids it. This is good for everyone.

Yes, the real gain, including the snake female finger bones, is not on Lei Lin at all!

Therefore, no matter how strict Gilbert's inspection is, it is completely useless!

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

The Black Scale was very fast. It took Leilin and his team more than a month to get from the area where the Weatherbus Ring is located to the City of Sin, but it only took more than ten days to return.

After returning to the headquarters, Lei Lin gathered with his teacher and several seniors for a while, and returned to Black Castle on the grounds that the wizard tower in the territory was about to be completed.

"Welcome to you!" Parker stood in front of the black wizard tower and saluted respectfully at Lei Lin, his voice still as old as ever. When he cooperated with his young face, he felt a strange feeling of confusion.

"How is my Wizard Tower built?"

Lei Lin stepped forward, stroked the black tower body, looked at the exquisite runes on it and the powerful energy fluctuations emitted faintly, and a smile appeared on his face.

"The overall structure of the Wizard Tower has been completed, with only a few cores and the most important tower spirit activations left! All of these are waiting for the master to come and complete!"

Parker's answer made Lelin very satisfied. He was very serious at work. The last time he told him to do something very well. He successfully delivered the letter to Grand Duke Gilbert, saving Lelin from his bad luck.

"Very good!" Leilin nodded.

"Another day, let Slubbie go to my lab. I haven't taught him something new in a long time!"

Of course he knew that Pike was old and no longer motivated. All hope was placed on his grandson, and no reward was as important as Slubby.

"I will thank the master for his behalf!"

Sure enough, after hearing Leilin's words, a hint of excitement appeared on Parker's face, and his waist was bent to ninety degrees.

"When I came back this time, I had already exchanged the activation technique scroll from the teacher and told me to go on, and I would complete my wizard tower immediately!"

Lei Lin gave the order calmly.

"Your will be executed!" Parker replied, all the construction preparations were completed, and several other core materials were also prepared, just waiting for Leilin to come back to lead the way.

Strolling inside his wizard tower, Leilin carefully observed every place.

The interior space of the Wizard Tower is very large, and all of them are built according to the highest standards. The facilities inside are very complete and look very exquisite and luxurious.

Lei Lin looked at one layer after another, especially two positive and negative energy pools, as well as laboratories, bondage rooms, ecological gardens and other places.

"Chip! How was the scan?" While watching around, Lei Lin did not forget to let the chip fully scan and record the arrangements he saw and the witchcraft array, and then check it.

"The main body of the Wizard Tower building has been scanned by 67.8%, and the defensive witch array is running intact, and the area can be optimized: 2 places!" The chip faithfully reported.

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

The remaining optimized areas are just small problems caused by improper construction and other reasons. No matter how perfect the plan is, as long as people control and master it, there will always be accidents. Lei Lin was prepared for this.

"The rest are all fine, but the previous ecological park can be modified and the ancient environmental data I collected in the Quicksand Castle will be added!"

Leilin touched his chin.

The Wizard Tower has not been completed yet, so you can still modify it now. If you wait until the defensive witch formation is activated, especially after the tower spirit is awakened, you really can't change it even if you want to.

"Chip! Design rectification drawings as I just said!"

Lei Lin has always liked to leave such cumbersome things to chips, but he just needs to grasp the general direction.

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

The chip was running rapidly, and in a few minutes a new drawing was projected onto Leilin.

"Well! I made the most of the original resources and settings, but I just needed to add a few more things and witch formations! That's it!"

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

He now has many subordinates and a large number of stone slaves. The rectification matter was just a little explained. Several teams took turns to start work day and night, and it was completely completed in more than ten days.

Lei Lin stood next to the negative energy pool at the bottom, looking at the complex witchcraft patterns on the ground, as well as the light emitted by precious materials such as pure gold and mitral. The expression on his face was neither sad nor happy, and he was calm.

"The overall witch formation simulation of the Wizard Tower was completed, with 341 rehearsals, and the number of failures: 0!"

Deep in Raylin's eyes, the blue light of the chip flashed by.

"here we go!"

Lei Lin let out a breath and put a piece of concentrated energy crystal emitting huge light and heat, like a small sun's concentrated energy crystal, into the groove in the center of the witch formation.

Buzz!

The entire witch formation immediately began to tremble, and circles of runes appeared out of nowhere, and a trace of light flowed on the witch formation.

"Activate!" Lei Lin's mental power spread out and was connected to the witch formation.

The moment his mental power came into contact with the witch formation, Lei Lin felt that he seemed to have opened a valve, and many energy particles were crazyly absorbed by the witch formation, and then they were transported into the negative energy pool through complex transformation channels.

And just outside the Wizard Tower, Pike, Gubler, Slubby and other Lehlin's men gathered together, with light in their eyes watching this scene.

The huge wave of elements seemed to form a vortex, absorbed by the black wizard tower.

One after another, the witchcraft runes brightened from the tower, and were connected firmly with terrifying and stable fluctuations.

At this time, there was only Lei Lin in the wizard tower. 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 formation and storage pool.

"The next one is the positive energy pool!"

A same high-energy crystal was pressed into the groove by Lei Lin, and the same excitation technique emerged from Lei Lin's hand and penetrated into the walls on all sides.

boom!

Above the Wizard Tower, a huge wave of elementals almost condensed into substance, and energy particles of various colors flowed over and over again, and soon settled, forming two rainbows of light and darkness.

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

Buzz!

The positive and negative energy pool kept buzzing, and the elemental liquid inside accumulated more and more, and finally reached halfway.

Two stars-like lights emerged from the spire and underground, and continued to spread toward the tower.

Many symbols lit up one by one and finally gathered in the middle of the Wizard Tower.

"The witch formations of the Wizard Tower are all activated! They are currently operating well!"

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

"The fourth-level witchcraft construct activation scroll!"

"Also, chips, prepare sub-agents!"
Chapter completed!
