After getting Yangzi's authority key, Du Yuqi rushed through the Iron Fortress as if he was in an empty space. Many passages that were previously closed to him only needed to walk through, and they would sense the authority key on him and open automatically layer by layer. Even a large number of transformed soldiers would obey Du Yuqi's orders.

Another very important point is that now that Kamaka knows that Yangzi has successfully escaped, most of his energy is focused on resisting the attack of the Imperial Army, and he has no time to care about Du Yuqi. The core content of the transaction between Kamaka and Misha is this steel fortress, so he must keep it at all costs and drive out the Imperial Army.

As for why the Joker went to the database, it was because he felt that the current situation was not very good and he was not sure that he could defend the Iron Fortress, so he was preparing for the worst and copied and burned a lot of precious information in it. This matter was also tacitly approved by Kamoka. Neither of them expected that an uninvited guest like Du Yuqi would suddenly appear! !

The database of the Iron Fortress is huge. It looks to be at least the size of an upright oil tanker truck. Its shape is more like a rocket launcher that is about to be launched. It is surrounded by colorful lights, which makes it look very mysterious. At the same time, there are more than a dozen robotic arms nearby that are busy poking and entering data.

The establishment and improvement of the database of each steel fortress requires a huge amount of manpower, material resources and experience, and it also takes several years or even more than ten years to build and run in. Other things can be accomplished quickly, but the parameters recorded during the constant operation over the past ten years cannot be false or tricky, and are the greatest wealth. Therefore, even if the steel fortress has to be destroyed, the contents of the database must be preserved no matter what.

The Joker was standing silently in the database at this time. Because his face was covered with thick oil paint, his expression could not be seen clearly. One could only vaguely see that he was in deep thought. The guards around him were not cyborgs, but a group of rat-headed people.

These guys had long swords slung around their waists and looked murderous. The one leading them was a cat demon, which was lying lazily on the ground. It had dark blue skin, and around it were four colorful runes the size of basins that kept spinning. It had a pale bone mask on its face, and no one knew whether it was born with it or was put on later. It looked very weird.

Suddenly, this dark blue cat demon stood up, then crouched slightly with its hair standing on end, letting out a threatening roar from its throat, revealing an extremely ferocious look. Terrible claws like poisonous needles shot out from the pads of its paws, causing the steel floor to squeak.

Then, a steel door beside him slid open quietly, and a sharp-eyed man walked in proudly. A translucent ghost dog followed him. When the man saw the clown, a sneer appeared on his face, and he pointed his finger at him:

"Joker, we meet again!"

The clown turned his head and took a look, then snorted with contempt:

"Who are you?"

The muscles on Du Yuqi's face twitched and he took a deep breath:

"Haha, very good, very good!"

After saying this, Du Yuqi waved his hand, and a large number of cyborg warriors appeared behind him. All of them had their permissions tampered with by Du Yuqi using the key he got from Yangzi, and they rushed towards one of them. What was even more shameless was that the focus of these cyborg warriors' attacks was all the database of the Iron Fortress! !

Although there is an energy shield on the database of this steel fortress, it is only set up for precautionary measures and the protection is not strong. Du Yuqi came with bad intentions this time and the first move he made hit the clown's weak spot.

These rat-headed warriors around the Joker showed their powerful strength in a short period of time. At least a dozen cyborg warriors were destroyed in an instant, but at the same time, the protective shield of the database was rippled and turned into a warning yellow. Once it turns red, it means that the protective shield is about to shatter.

Seeing this scene, the clown was also extremely anxious. He immediately shouted to his rat-headed warriors to prioritize protecting the database at all costs, even at the cost of their own bodies. The effect was immediately much better, but the number of casualties among the cyborg warriors also dropped. These monsters who did not know fatigue or pain faithfully carried out Du Yuqi's orders and rushed forward one after another. The rat-headed warriors were beaten so badly that they began to suffer casualties.

To be honest, these rat-headed warriors around the Joker were quite powerful, far superior to the cyborg warriors, but they were made to suffer by Du Yuqi's tactic of going straight to the vital points.

Seeing that his side was at a disadvantage, the clown immediately waved his hand and said sinisterly:

"Experimental subject Hanik, go!"

The cat demon with a strange bone mask immediately pounced forward with a howl. It can be seen that its movement speed is not fast, but its attack speed is dazzling and extremely fast. At the same time, its claws are extremely sharp, and there seems to be some curse on them.

An elite cyborg warrior was approached by the experimental subject Hanik and was hit by just one claw. The blood, tissue fluid, engine oil and other substances in the warrior's body spurted out from the wound and reached five meters away. It was like a blood fountain. After a few seconds, he was successfully bled out and fell to his knees and died!

However, as soon as the experimental subject Hanik made a move, the ghost wolf Daka also joined the battle. Daka jogged for two or three meters, then suddenly accelerated, pulling out specks of light behind him, and instantly slammed into the body of the experimental subject Hanik as if teleporting, knocking the strange cat demon more than ten meters away, shaking its head and seeming dizzy.

Then Daka took advantage of the victory and pounced on it, opening its big mouth and biting it hard. It looked like an illusory ghost, but in fact it could also launch extremely powerful physical attacks. The experimental subject Hanik barely avoided the vital points and was bitten by Daka on the right back, and a large piece of flesh was immediately torn off. What was even more terrifying was that Daka's attack type was sacred, and it was also in a state of disintegration, so a large amount of holy light power remained in the wound, burning the flesh and blood and making a squeaking sound.

However, Du Yuqi keenly noticed one thing at this time, that is, after the experimental subject Hanik was injured, it can be seen that the muscles at the wound were rapidly contracting, and only a small amount of blood flowed out before the bleeding stopped. You know, it was a wound the size of a bowl. Such an injury stress mechanism can only mean one thing, that is, this experimental subject was completely developed from the perspective of combat, and even the stress response after injury was developed in this way.

After the experimental subject Hanik was injured, he immediately fought back quickly. Du Yuqi had noticed before that his movement speed was not fast, but his attack speed was astonishingly fast. Even Du Yuqi could only see a series of afterimages passing by.

However, the biggest threat of Hanik's attack was that it caused extremely horrible bleeding damage, but the ghost wolf Daka was an out-and-out spirit, without even flesh, let alone blood. Therefore, this was very embarrassing. After a round of attacks, Hanik had two more hissing wounds on his body, while the ghost wolf Daka's body only became a little lighter in color, and he still raised his head and wagged his tail, still as ferocious as ever.

In fact, for a creature like the ghost wolf Daka that is made entirely of holy light, the best way is to use elemental attacks. For example, dark elements can cause tit-for-tat damage, while physical attacks have little effect.

The clown was also a veteran, with a gleam of brilliance in his eyes. He was about to step forward to help, but suddenly he felt a strong sense of threat coming from the right. Turning around, he saw Du Yuqi holding the blazing Kulan's Flame Shadow Sword and pointing it coldly at him!

The clown saw Du Yuqi's action and raised the corner of his mouth. This action made his already weird smile even more exaggerated, and then he let out a series of sinister laughs:

"Haha, hehe, hahahaha, this is really funny. I've actually been looking for you the whole time, but I didn't expect a bug like you would come to me on your own initiative! Oh, although your flesh and blood and soul are only worthy of supporting a shabby stage play, perhaps you can bring me a little happiness."

After he finished speaking, the clown turned his wrist and a skull suddenly appeared in the palm of his hand. However, the skull looked only the size of a fist, and as crystal clear as if it was carved out of crystal. Behind the skull, there were shadowy and distorted illusions of various colors, floating and wailing, which looked very strange.

Although Du Yuqi hated the clown very much in his heart, he did not have the slightest intention of looking down on him. He stared at the clown's every move, fearing that he would miss any of his actions.

The clown suddenly looked up, with an even more intense evil smile on his lips. At that moment, the crystal ball in his hand suddenly emitted a dazzling purple-black light, which instantly made Du Yuqi's eyes extremely painful and he completely lost his vision!

Du Yuqi had been concentrating on staring at the clown. This attack was unexpected. He screamed in his heart that something was wrong and quickly retreated to the back. The clown laughed loudly and said:

"Come, descend, Spider Prince Nicholas, revel in the land of blood and shadows, and taste the regret of your enemies in the abyss of pain and despair!"

Du Yuqi was enduring the pain at this time. She could vaguely see through her tears that a tall and thin shadow slowly walked out from the shadow behind the clown. He was wearing a top hat and a tuxedo, and looked like a thin nobleman, but an indescribable evil aura emanated from his every move. After bowing slightly, he slowly merged with the clown.

This was the Joker's trump card. He had realized the secret of Coming: Tyrant Baroque in advance, so even though his strength was limited and he couldn't perform this move, he was able to strengthen the secret to his other skills and mutate them - summoning the powerful spider prince Nicholas to merge with himself, allowing him to use some of Nicholas' special abilities, while also comprehensively improving his own attributes.

From this we can see that although the Joker was extremely contemptuous of Du Yuqi, he actually attached great importance to him in his heart, and he directly played one of his trump cards as soon as he arrived!

Du Yuqi's eyes were still sore at this time, but the clown had already pounced towards him, and the illusion of the Spider Prince Nicholas appeared behind him, and he dug down with one claw. It seemed as if the heaven and earth were trembling and resonating after this claw was made.

Du Yuqi was unable to counterattack at this time and could only use his blocking skills to block Kuran's Flame Shadow Sword in front of himself and take the clown's attack head-on.

There was a crisp "clang" sound, and the clown's left hand came into close contact with Kuran's Flame Shadow Sword, which made a crisp sound of metal collision, and even a black gas spread up, causing the flame burning on the surface of Kuran's Flame Shadow Sword to fluctuate, almost going out.
