Green originally thought he had to take action, but he didn't expect that the female assistant beside him was extremely powerful. Not only was he not killed, but he was fierce and forced to retreat the cute girl like a wolf dog in the blink of an eye, and he also sinisterly killed the unlucky man with the soul key on his back.

However, Green also realized that this female assistant was probably not simple. According to the memory he obtained from Dr. Vinson's mind, although this female assistant is not weak, she is completely academic and has little practical experience. What she can become an assistant is her administrative ability. However, the strength shown by this female assistant just now is extraordinary and vicious, just like a veteran who has been walking on the battlefield for many years, rich in experience and quick reactions.

"Did this woman be lost too?" Green was judging others by her own heart, and suspected that the female assistant might be fake, or that the female assistant was a spy who had been scrambled to Dr. Vincent. Green thought to himself while looking at the wooden box that fell to the ground, because the battle between the cute girl and the female assistant was getting farther and farther away from here, and now the closest to the wooden box was Green, but Green didn't plan to pick up that thing, because so many people suddenly appeared at the underground base, all of whom were snatching the key of soul, which made him smell a scent of conspiracy.

Green thought for a moment, simply ignored the wooden box containing the key of soul, turned around and ran upstairs.

Green's actions made the two women downstairs frown, and their eyes were intertwined invisibly. Until Green escaped to the upper floor, although they were still fighting, they no longer used killer moves. Instead, they were more like a common practice between companions.

"I didn't expect you to lurk here. No wonder I haven't heard of you since the mission five years ago. However, your strength has not yet fallen behind, and I have completely deceived me and killed that trash." The cute girl whispered, and actually knew the female assistant beside Dr. Vinson.

The female assistant also smiled slightly: "I have no choice but to do the task issued by His Highness the Princess, but it's here. My identity must have been exposed this time."

"Okay, let's not fight anymore. The large army of the base and the mysterious No. 0 will come soon. We can't be surrounded, take the key of the soul, and let's go." The cute girl said as she jumped back. Although she recognized the identity of the female assistant, she did not relax her vigilance.

The same is true for female assistants. People like them have to open half of their eyes even when they sleep. Believe in their companions? Forget it, the unlucky guy who carried the key of the soul just now was a role model.

Because of the special nature of the Soul Key, the cute girl didn't expect her female assistant to help her carry it. She flicked out a silk thread and wrapped it around the wooden box. She actually lifted it up out of thin air, as if she was floating in the air and following the cute girl.

At this moment, a sudden "boom" explosion came from the base. The two of them were stunned for a moment, all looked at each other, and asked in unison: "Is it yours?" Then their faces became serious, and they realized that there was another group of people besides them.

Green knew that this explosion was probably the one who had let the young man who pretended to be a researcher before, and thought to himself: "The other party's purpose of coming here does not seem to be the key to the soul. Kill Dr. Heathrower and the semi-finished No. 1, I don't know what he got..."

Thinking of this, Green's eyes suddenly lit up. Could it be that the real purpose of the young man who sneaked into the base was the core of the divine power in No. 1's body?

After thinking about it, Green seemed that this thing was the most valuable. And now No. 1 is just a semi-finished product, bound in the laboratory and has no combat power at all. As long as he sneaks in, he will be the easiest to succeed.

To confirm this guess, Green immediately summoned a ghost to check on No. 1's body.

Sure enough, no core of divine power was found.

"Is it a coincidence? Or is it deliberately covering the action of stealing the soul key below? It's really lively!" Green sighed in his heart, but he kept walking quickly into a room next to the corridor.

After a while, the female assistant and the cute girl rushed up from below and could no longer see Green.

The female assistant said "Huh". She wanted to treat Dr. Vincent as her last trump card, but she hijacked Dr. Vincent if she really couldn't do it, but she didn't expect that in the blink of an eye, the person was gone! She was also very smart, and her eyes swept across both sides. It was believed that Dr. Vincent was probably in these rooms, but now what they lacked the most was time and they had no time to look for it.

"Damn it, he hid it. It's too late. Let's go." The female assistant made a decision in an instant without hesitation.

The cute girl had no hope from the beginning, so she rushed over simply.

At this moment, there was a sudden bang, and a loud noise and the tremors of the entire base were heard, followed by a heart-wrenching roar.

The female assistant's face changed slightly, as if she had thought of something terrible. She showed a terrifying expression on her face and shouted, "Go away!" Then, regardless of whether the cute girl followed or not, she rushed outside as if she was flying.

The cute girl was a little confused and didn't know what was going on, but he knew the female assistant. Seeing the other party's reaction, he knew that something must have happened. He hurriedly followed.

At this time, the vibration of the entire underground base became more and more serious, and even slightly tilted. You should know that this is underground. The buildings on the ground collapsed if they say they collapsed.

Green hid in one of his rooms, frowned, searching for memories, and soon knew what was going on: "Who gave the order? He actually released that thing? There are no more than three people with this authority in the entire base. Could it be that Zero has come back?"

The female assistant's face looked extremely ugly at this moment, and she also thought of that terrible thing.

The cute girl who caught up behind asked, "What the hell is going on? I scared you like this?"

The female assistant said: "It's the black angel! Someone released the black winged angel..."

After a brief explanation from the female assistant, the cute girl was frightened and looked ugly, and she couldn't help but speed up: "Damn, then we have to run away quickly, otherwise we have to be cannon fodder."

It turns out that there is actually a corpse of a black-winged angel left in ancient times hidden in this underground secret research base! In fact, the human transformation technology and core divine power mastered by Duke Fra and Zero are all rooted in the corpse of this black-winged angel. It can be said that the angel corpse called the "Black Angel" is the basis of the entire human transformation system.

Even half of the Void World No. 26 is a realm of the undead, in part because the powerful six-winged angel died here. Princess Mulesina had searched before. She did not know the existence of the angel's corpse, but tried to find the source of death psychic energy in the Void World, but for various reasons, she did not succeed in the end.

However, with in-depth research on the angel's corpse, Duke Fla, Zero, and several top scholars from the experimental base including Dr. Vinson have discovered that the angel's corpse is actually reviving!

Of course, this resurrection does not mean that the angel is resurrected, but that the angel's corpse is transforming into an undead creature.

This corpse, which itself is a six-winged angel, must have been a powerful existence at the natural disaster level or even the holy spirit level. Once it is successfully transformed into a deceased creature, it must be a terrifying existence at the natural disaster level. Even Princess Mulesina may not be able to suppress this undeceased angel.

Therefore, everyone almost unanimously believes that the transformation of the Black Angel must be prevented.

Therefore, before, the black angels were stored in the deepest part of the base, and used a special magic array to completely isolate everything, preventing the dead spirit from eroding it and further transforming it into an undead creature.

However, just now, I don’t know who gave the order, or directly destroyed the magic array that sealed the Black Angel, and injected a large amount of death psionic energy into it, which further promoted the rapid transformation into an undead creature.

At first, Green thought it was an order under No. 0, and in order to regain the stolen soul key, he began to do everything he wanted.

But I felt something was wrong with Kuai Green. Even if Zero was furious because of the stolen soul key, I should not release the black angel, because it would not help at all. Instead, it would completely destroy the most important experimental base. Such a loss would never be possible unless Zero's head was kicked by a donkey.

Then who released the Black Angel?

Green seemed to have some clues in his mind. Why did so many people suddenly stare at this base? Why did Grand Duke Mora's news come here at this time?

Is it really for a soul key that seems important but actually has no value?

It’s not that Green looked down on the Soul Key, because it’s really because the creation of the Soul Key is not difficult for real big shots. Even if you take away one and take some time, you can create another one, at least you can die more.

But for those big men, what is the dead? From Green's journey to this world, who has experienced one after another, and who has the highest nobles and extraordinary people who have mastered powerful power, has ever cared about the life and death of ordinary people!

"This is the intention of the drunkard, not wine!" Green's eyes lit up, and he suddenly figured out something: "It's Princess Mulesina! It was because of the internal strife between Duke Fla and No. 0 that the secret here was finally revealed, or it was Duke Fla who deliberately revealed it, attracting Princess Mulesina's attention."

Princess Mulesina has been promoted to the natural disaster level for nearly twenty years. She is determined to obtain a natural disaster level undead summon, but she still has no choice. After discovering this place, she will definitely get the body of the six-winged angel at all costs. However, the situation in this void world is now turbulent, and all forces are mixed together. She is not able to take action rashly, so she first finds a way to use the key of soul to muddle the water...
