As these waste crystals collapsed and turned into flying ash, and among the dust, huge eggs were revealed.

"Oh no, those subjects still have ...... here," Alpha exclaimed, too.

But it's not because the magic crystal and kara crystal here are lost because of too much time.

Instead, there were experimental subjects mixed in, relying on these crystals, which survived for tens of thousands of years.

If this is the case, it is likely that the subjects are not degenerating.

"Don't panic," Yin Shengzhi sneered: "These test subjects have degraded and formed cocoons, and they must have run out of crystals later." I can only sleep and get through the time. Even if he didn't die now, he was extremely weak......"

Yin Shengzhi was able to calm down, even though his Hell Castle had been destroyed and had lost his strongest combat power.

But Yin Shengzhi still has a sober judgment at all.

However, just as Yin Shengzhi said these words, suddenly a giant egg made a cracking sound and cracked, and a black human hand covered with scales was deep in.

Alpha was taken aback: "Oh no, this test subject is coming out......"

"No, it's dead!"

Yin Shengzhi said lightly.

Sure enough, the black scaly palm stretched out, and there was no movement for a long time.

When Yin Shengzhi walked to the side, the giant egg shattered, and all that was left inside was really a corpse.

This corpse was very similar to the lizard monkey that Yin Shengzhi had seen at first, but it was huge, more than ten meters tall, like a small mountain, but it looked extremely old.

The scales and so on have long since lost their luster and are covered with wrinkles.

"To be able to survive until now before dying, the vitality of these test subjects is really strong enough!"

Yin Shengzhi said, these giant eggs did not move.

He examined it, and found that although there was still life force among the giant eggs, it was very weak.

Obviously, even if these test subjects are asleep, the time of twenty or thirty thousand years is not easy to pass.

There are more than 80 giant eggs in total, and most of them have lost their vitality and are completely silent.

There are only three giant eggs, and there is still a very faint vitality coming out.

"Don't do it, I have a way to control them......" Alpha suddenly exclaimed.

It's a pity that he said a little late, and before he was halfway through his words, the three giant eggs had already been burned to ashes under Yin Shengzhi's mana.

"You didn't say it sooner......"

He didn't have much fear of these test subjects, no matter how strong the individual strength of the test subjects was, Yin Shengzhi would not be afraid.

The most feared thing about the world-destroying monster is not its individual strength, not even its group strength, but its powerful "contagion" ability......

Alpha was dumbfounded: "It's your shot that is too fast...... Okay, dig out the central spars of these test subjects and see if you can use ......"

As a result, it was found that the central spar of the brains of these test subjects had long since disappeared and decomposed.

But in the long sleep time, even the central spar has broken down to provide energy for the body.

Only the last three subjects in the giant eggs with weak life have not completely disintegrated the central spar in their brain, leaving behind a central spar the size of a fingernail.

"Well, anyway, with these hedrons, the experimental data is still there!" Alpha muttered to himself, kind of self-comforting.

Among these crystals, there are countless maze patterns, which are the most important experimental data.

Fortunately, Yin Sheng still has the Willier Stone in his hand!

This thing, although it can't sanctify spiritual power, is enough to expand the realm of the Demon Palace and can replace a large part of the role of the magic crystal.

However, before that, you still have to repair the Hell Castle first, after all, you must have the ability to defend yourself at all times!

Yin Sheng's heart moved, and Connorives had flown back and sat in the castle of hell.

As long as he is still there, there is the labyrinthine structure of the Hell Castle, and rebuilding the Hell Castle only needs to be refilled with energy.

Alpha also flew back, seeing Connorives channeling the energy of the Willidor Stone and wanting to restore the Hell Castle, he suddenly spoke, "Wait, in fact, I think the Hell Castle doesn't need to be repaired as it is!"

As soon as his words came out, Yin Shengzhi and Conner Levis were stunned.

"After all, this young mage is not the inheritor of your Francis, and he is not very familiar with the astral plane. The original hell castle may not suit him very well!"

"This is my castle of hell!" cried Connellives.

"So what, the Hell Castle has been destroyed anyway, so it might as well be redesigned...... Well, I mean strengthen, we can make a little improvement to the Hell's Castle!"

Alpha's words suddenly made Yin Shengzhi's eyes light up, and he felt good.

He didn't improve the ability of the Hell Castle, after all, the labyrinth structure of the Hell Castle was designed by Archmage Connorlives, and it was definitely not something that Yin Shengzhi's current ability could change.

But Alpha can!

His mastery of advanced labyrinth knowledge is definitely not below Archmage Connorlives, or even surpasses it!

"How are you going to improve?" Connell Levis hesitated.

Hell Castle has been breached several times, which shows that Hell Castle is not flawless.

And as Alpha said, Hell Castle is too much of an astral plane.

"I can keep the functionality of Hell's Castle while trying to improve it to make it more combat-friendly.

But I need time to redesign. Don't worry, it won't be long. ”

Just do it, at that moment, Yin Shengzhi went to the bottom of the mage tower to find steam boilers and other things, and sure enough, he found a large amount of coal.

Thankfully, the place was probably not very important, and was not destroyed by the subjects.

The puppets in Yin Sheng's Hell Castle are dead, but fortunately there are still puppets in this place, and they are also very rare alchemy puppets, all of them are like stone statues, under the manipulation of mana, transporting coal and burning boilers!

"These alchemy puppets are very good, although they can only perform very simple activities......

Yin Shengzhi's eyes rolled, thinking that the technology to create this alchemy puppet was all available in Alpha!

As the huge steam boilers boiled, column after row of steam differential machines began to operate, and under the auspices of Alpha, the redesign of the castle of hell began.

Alpha said it wouldn't take long, and sure enough, it wouldn't take long.

Soon a new maze diagram came out.

Of course, this is not something he designed from scratch, but Alpha synthesized it with ready-made information.

After all, there were nine experimental spaces in Franklin, and in each of them, there was a mage tower.
