After entering the ancient castle, Ye Feng found that all the doors and windows in the ancient castle were closed, and there was no light here, which was particularly eerie. However, with the help of the night vision function of wearing glasses, Ye Feng can also see all kinds of objects inside.

Soon Ye Feng found in the darkness that the kind of light that was intertwined into a web was almost everywhere, if it weren't for his spatial ability, it would be absolutely impossible to move an inch here.

Ye Feng observed slightly, his figure flashed and passed directly through the space, and after coming to a staircase in the middle of the hall, his body suddenly disappeared there again.

Behind the stairs, there was a portal to the basement floor, and Ye Feng directly passed through this portal and entered the basement floor. At this time, Ye Feng's tense heart became a little calmer.

Because after arriving here, it is the territory of Nianzi's wisdom and brain again. The most dangerous place is the safest place, and although the defenses are terrifying, this can only make the guards take it lightly. So, with Linglong's help, Ye Feng quickly found the entrance to the next floor and entered the second underground floor.

Along the way, Linglong either told Ye Feng about the defense situation of Ye Feng's location, or directly dismantled or cracked the security system, all the way to the twelfth floor underground, without causing any fluctuations in the security system.

"Thirteen floors underground, where I found a lot of staff working. At the entrance to the thirteenth floor, Linglong suddenly prompted in Ye Feng's mind. By here, due to the proximity of the distance, Linglong had been able to establish contact with those independent networks through her thoughts, so that she could know the situation on the next level.

"There are a lot of people?" Ye Feng said silently in his heart, but the movements of his hands did not stop at all, and he passed through a security door like a cloud and appeared in a long corridor. This place is very different from the previous floor, not like a security center, but like a hospital corridor, painted everywhere is extremely white, and under the light, it looks extremely spacious and bright.

One of the walls of the hallway is full of glass, and through the glass, you can see that there is a large space outside. There are countless devices painted in white, with lights of various colors flashing non-stop, and almost every device has a large display showing all kinds of strange curves. Many staff members in dust-proof suits were shuttling between the equipment, as if they were busy with something.

"This is the secret research institute of the Lockward Corporation?" Ye Feng looked at everything in front of him in surprise, his eyes were full of incredulity, if he hadn't seen it with his own eyes, who would have thought that there would be a cave under this abandoned castle.

When I got here, except for some cameras, there were no more complicated security systems, and Ye Feng was safer.

Ye Feng came here to explore the secrets here, so naturally he was not in a hurry to rush to the next layer.

Ye Feng's figure flashed and appeared in the shadow of a tall machine, and there was a strange sound from the inside of the machine beside him.

"What a strong smell of blood!" Ye Feng subconsciously took a breath and immediately noticed the strong smell of blood in the air.

"What the hell is going on here?" Ye Feng's eyes became more solemn.

"Linglong, hack into the system here immediately and see what the hell is going on here?"

With such a close distance, Linglong was already able to easily hack into the network here.

"Yes! "In fact, when Ye Feng first entered here, Linglong had already begun to try to invade the system here, and when she heard Ye Feng's order, she immediately went all out to invade.

In just a few breaths, Linglong mastered the network system and began to download the information in it.

"Cyborg?" Ye Feng had a hint of horror in his eyes, and then he felt like he wanted to vomit, he actually used a living person to conduct a cyborg experiment here!

He flipped through the materials downloaded by Linglong, and could see that there was also a secret warehouse on this floor, and there were huge round glass containers erected in the warehouse, which were filled with green liquid, and they were all covered in blood red, as if the skinless humanoid monsters were soaked in the green liquid, and their bodies were filled with various tubes.

"Those are cyborgs who are invulnerable, have infinite strength, and can even regenerate their bodies, how dare they use death row prisoners to conduct such research!" Ye Feng's expression was a little angry. If he exposes these to the media, I am afraid that it will cause an uproar in country M and cause a storm, and I don't know how many people will be unlucky because of this scandal.

"I don't know how far they have become a graduate student? These studies must also have the military background of country M!" Ye Feng thought about it for a while, and put these things behind him first.

Now that Linglong had downloaded all the materials, he began to move towards the next level. He ventured here, not to steal these materials, but to find a way to quickly allow him to cultivate a breath of Dao Qi.

From this level down, there are many people on each floor who are busy conducting various experiments and researching a variety of things, but the topics of study on each level are by no means the same.

There are those who study exotic materials, those who study super energy generators, those who study black holes in space, and even those who study space and time...... These studies are at the forefront of science and technology, and they are inconceivable to ordinary people. It's no wonder that the internet here isn't connected to the outside world.

Every time Ye Feng passed through the floor, he asked Linglong to raid the computer network on this layer and download all the research results, so that Linglong could deduce them according to these in the future.

Soon Ye Feng reached the twenty-eighth floor underground, and Ye Feng was slightly stunned when he arrived here. Here he suddenly felt a particularly familiar feeling.

That's right, the layout of this floor is exactly the same as the layout of the hall on the thirty underground floors of Dr. Chen Yunfei's National Artificial Intelligence Laboratory.

"I'm also studying the Nianzi Theory here!" Ye Feng's expression moved slightly, and his gaze was projected on the machine in the middle of the hall, and there was a huge transparent spar on the machine, but he didn't sense the slightest spatial fluctuation from it.

"Without the Space Divine Stone, how could it be possible to study the Nianzi Zhi Brain?" Ye Feng sneered. He now understood that Linglong's appearance was no accident, and it was with the second Spatial Divine Stone he obtained that he could carry Dr. Chen Yunfei's Nianzi Artificial Intelligence Program.

The Space Divine Stone and the Nian Zi have a strong fit, and only the Space Divine Stone can withstand the energy of the Nian Zi Zhi Brain.

"Operation Broken Wings!" Ye Feng was not polite, and began to flip through the information here, and soon stopped his eyes on the words "Operation Broken Wings".

Operation Broken Wings: On May 18, 2017, Robert led agents to infiltrate the ...... in China

This date, how could Ye Feng forget, it was the day he got Nianzi Zhizhi's exquisite brain.

The lines of text were shocking, Ye Feng's face became a little ugly, he didn't expect to see a top-secret information here. The agents who infiltrated the National Artificial Intelligence Laboratory in China before turned out to be the handiwork of the Lockward Corporation.

"Liu Shuntian, Han Tielong......" familiar names jumped into Ye Feng's eyes, Ye Feng's face turned red, and he didn't have anything to do with the action of country M to steal the research of Nianzi's wisdom brain, after all, this is the master of each one. But there are some Chinese people, these people who are in China or have high positions or have a lot of wealth, but they sell their country for their own selfish interests, how can Ye Feng not be angry?

And Liu Shuntian and Han Tielong are the two people who play the biggest role among these people, and it is with their help that those agents can successfully lurk in Huaguo.

"These people deserve to die!" Ye Feng's eyes flashed with a chill. After this incident, these people must not be allowed to continue to plague China. Although Ye Feng is not an angry youth, he still loves his country very much in his bones, and loves this civilization that has been inherited for thousands of years.

"When I finish exploring this place, it's better to destroy this place!" Ye Feng's eyes flashed with a cold light.

He has a delicate brain of Nianzizhi, and he really knows the horror of Nianzizhi's brain, and he can completely return a country to the primitive era with a single thought. Although the research on the theory of Nianzi here seems to be still in the primitive stage, far inferior to Professor Chen Yunfei's research, let alone Linglong, he can't let them develop.

"Master, do you want to leave some viruses here?" sensing Ye Feng's thoughts, Linglong suggested in Ye Feng's mind.

"Okay!" Ye Feng nodded, and then Linglong injected a virus into all the computers here. Linglong, a complete mindset brain, is too easy to deal with the sporadic mindset program fragments here. It felt like an adult boxing with a newborn child, not an order of magnitude at all.

After dealing with all this, Ye Feng quickly found the entrance to the next floor. Just looking at the gate in front of him, Ye Feng's expression became strange, this gate was like a huge piece of complete metal, there was not the slightest trace of electronic systems in it, and some were just sophisticated mechanical devices. And it looks like the door hasn't been opened for years.

However, while the gate is sturdy, it can't block the spatial ability. Ye Feng just thought about it, and there was a distortion of space around his body, and he had already passed through the door.

When he reappeared, endless darkness overshadowed his eyes. Ye Feng hurriedly put on the pair of glasses with night vision function, and only then did he see clearly in front of him vaguely. Since there is hardly a glimmer of light here, it is not clear to see with the night vision glasses.

Ye Feng thought about it, and a strong flashlight appeared in his hand, and then a snowy light broke through the darkness, allowing him to immediately see the corners of this layer.

The huge floor, except for a few swarthy walls, was empty. And it seems that no one has entered it for a long time, and a thick layer of dust has fallen on the ground, giving off a strange musty smell.

Ye Feng walked in curiously, leaving a clear line of footprints on the dust on the ground.

"What are they doing on this floor? There's no elevator here. Ye Feng's face became more and more confused.

Ye Feng exclaimed in surprise, suddenly walked to a wall, and put his hand on the dark wall. The walls are cold to the touch. Ye Feng immediately realized that the walls here were by no means made of reinforced concrete.

Thinking of this, Ye Feng had an extra sharp dagger in his hand and stabbed it towards the wall.

With a snap, the dagger snapped, and the military dagger only made a small mark on the dark wall, through which a shiny metallic luster shone through.

"The walls here are made entirely of metal. Ye Feng was shocked.

"Yes, it seems that it should still be the hardest titanium alloy!" Linglong's voice became unusually solemn.
