The magnetic grinder designed by Cook is actually a very simple thing, which is nothing more than the use of high speed to polish this star sand, of course, this kind of grinder can only be used by Cook, after all, the power of this star sand's rebound after acceleration is very great.

Of course, these forces were offset a lot by the magic patterns in Cook's settings, but even so, the grinder vibrated extremely strongly, but fortunately, Cook's power was very large, and this vibration was acceptable.

"Puff puff puff. "The grinder made a popping vibration sound, and tens of thousands of high-speed star sand in the grinder kept hitting the star sand ore, and the star sand that kept falling on the star sand ore made the number of star sand in the grinder continue to increase.

Half an hour later, Cook stopped the grinder, and then looked at it, and a pit several centimeters deep appeared on the original star sand, which was still uneven, and Cook was so excited.

Then Cook put away the excess star sand, and then Cook sanded it again, and the excess star sand must be taken out, otherwise too much star sand will be clogged in this grinder.

Half an hour Cook collected the star sand, this harvest is already a lot of money, the star sand has been an extremely precious magic material since ancient times, as for the destruction of this mage tower, Cook will not feel distressed, it will definitely not, because this thing is not Cook, if it is really Cook's, then Cook does not need to destroy it.

For a day and a night, Cook kept his vigilance, especially in the end, why, because this star sand is extremely fast after passing through the accelerator, in case this star sand shoots into the inside of the mage tower at high speed, this Nima is the thing that polishes the original ore of the stellar sand, what can be in this mage tower that can withstand such a strong speed and impact force?

"Sonorous. Cook poked the base of the mage tower with his thunder teeth, and found that it had not been broken yet, Cook sighed a little, this base is already nearly a meter thick, and the star sand collected by Cook alone is thousands of tons, of course, the volume is not large.

Start the grinder again, this time Cook takes a ten-minute interval at a time, and then checks it out.

"Boom. With a bang, the grinder poked straight in.

"It's broken. Cook hurriedly dropped the grinder and looked through the hole.

"Boom. But when Cook's head stuck in front of the hole, a huge air pressure directly sent Cook back several steps.

Then Cook's spiritual power stretched into the mage tower, and the scene inside surprised Cook, the space inside was not very large, only thousands of square meters in size, of course, Cook was the bottom layer to view, and there was an isolation shield between the second layer and the first layer, so Cook couldn't see what was going on on the second layer at all.

Cook's spiritual power was carefully examined, and after tinkering for more than half an hour, the luster around the entire mage tower gradually dimmed, and then the door of the mage tower opened suddenly.

"Hey, hey. Cook smiled and strode into the inside of the mage tower.

"Sure enough, the atmosphere, the atmosphere, actually use this magic pattern. Cook sighed, this mage tower is the highest mage tower Cook has ever seen, the magic patterns inside the mage tower are all compound magic patterns, and each compound magic pattern is composed of more than eighty individual magic patterns.

What kind of concept is this, even Cook's scimitar has not used such a high-level compound magic pattern, the compound magic pattern is a high-level magic pattern, and every time the compound magic pattern increases by a single magic pattern, the increase of the compound magic pattern shows a geometric multiplier.

Cook didn't rush to the second floor of the mage tower, not that Cook didn't want to see what the second floor was, but that Cook wanted to carefully check the magic pattern, and then judge what type of structure this mage tower was according to the method of setting up the magic pattern, so he could be prepared.

The entire hall on the first floor was empty, and there was nothing in it, and after Cook had observed it for a long time, he was somewhat sure, and then Cook came to the place between the second floor and the first floor.

It was also an isolation shield, and Cook quickly unraveled it, but to Cook's surprise, this was not a staircase, but a teleportation array, a simple teleportation array.

This time Cook hesitated, if it was something like a staircase, Cook could easily enter it, but what about this teleportation array, because he couldn't see what was behind this teleportation array, what kind of environment it was, so Cook hesitated a little.

After hesitating, Cook took a closer look, although Cook couldn't view the teleportation array, but Cook could roughly infer the distance of the teleportation from the structure of the teleportation array, and of course that's all.

The magic pattern circuit shining on the teleportation array was extremely clear in Cook's magic eye, the direction of the magic power, the circulation speed of the magic power, and so on.

As soon as Cook saw a flower, he appeared in a space thousands of meters wide, but the space gave Cook a creepy feeling, thousands of skeletons, and what made Cook feel even more strange was that these skeletons were arranged so neatly, as if someone had done it on purpose.

"What's going on?" Cook's mind was in turmoil at the sight of this.

Then Cook took a deep breath, and then Cook walked in, yes, these skeletons are exactly the same as humans, almost no difference, and they are not demons, yes, the bones of demons are very different on the top of their heads.

"Humans?" said Cook, looking at the human skeletons, and then surprised.

Then Cook took a closer look and found that the skeleton was not said to have died horizontally, but slowly died of old age, and the oldest of these skeletons was more than one hundred and fifty years old, which was already the longest life expectancy of a normal human being.

"How is it possible, it's a human in this?" Cook was even more full of questions.

Arguably the most striking thing about the entire second floor is the thousands of skeletons, and Cook has no idea how these skeletons died here, and there is nothing else around.

Soon Cook saw the teleportation array of the third layer, Cook carefully checked it and stepped in, Cook just stepped into the third layer, he was stunned, a forest, a forest that could not be seen at a glance, Cook subconsciously looked back and found that the teleportation array behind him was still there.

"This Nima has the style of a top-level mage tower!" Cook was amazed, in the forest, there was a thousand-meter-high building, this building was like a huge mushroom, and the snow-white roof looked so dazzling in the forest.
