As soon as he entered the elevator, the door of the elevator closed instantly. Then, without any warning, the elevator went on the "freefall" mode. However, there seemed to be something stabilizing around the elevator box, making the elevator extremely stable.

While the elevator was falling down, Yang Song also spread out his Spiritual Sense along the way.

Several minutes later, Yang Song's Spiritual Sense came in contact with the ground right underneath the elevator and his Spiritual Sense detected a kind of energy field that he had only heard of but never seen – non-gravitational field, in other words, anti-gravitational field.

Then, the originally freefalling elevator was forced to fall become slower and slower. When the bottom of the elevator touched the ground, the anti-gravity device automatically deactivated and Yang Song felt normal again.

Yang Song had to sigh at the black technology of this place again when he exited the elevator, "Even the elevator is tempered with anti-gravity technology, I wonder what other kinds of black technique will this place present to me?"

Yang Song was not worried about being spotted by other people when he exited the elevator at all because the other people were all dead. But even so, Yang Song at this moment was in the appearance of the real Yan Fei.

Corpses in black scientist coats were lying on the ground all around. Yang Song simply walked over and started checking the corpses.

When the cause of death was found, Yang Song was quite stunned. It turned out that these people all died from a heart attack, which was the same as those people above.

"What in the world really happened to these people?"

To cause one to have a heart attack, it was a very easy thing to do for Yang Song. However, normal martial artists could not do so because True Energy would be needed in order to achieve that effect.

Yang Song could cause a person to have a heart attack by controlling his True Energy to penetrate the body of the other party so that his True Energy could entrap the heart and tempered with it. However, great attention would be needed. Yang Song's current cultivation base could not possibly allow him to squeeze the heart of people so easily.

This was also the reason why he did not use this kind of method when battling with the enemies as it would consume too much time and energy.

"But since they died of the heart attack, something must have happened to the hearts. So let's… explore the heart."

Immediately after, Yang Song dived his True Energy and Spiritual Energy into the body of a corpse and simply inspected the heart. The process was a bit cumbersome as Yang Song's Spiritual Sense had to enter the body via the mouth before arriving at the heart area.

When Yang Song saw the dead heart of this certain corpse, he was quite shocked.

Around the fleshy heart, there was a small square chip attached to the heart. And what attached to the chip was a thin transparent string that squeezed around the heart.

Yang Song took his Spiritual Sense back and inspected the other corpses. The result was exactly the same.

Attaching the chip to the heart… it was not the first time that Yang Song had heard of it, it was just that this kind of thing was only seen on novels and this was the first time that Yang Song saw it with his own eyes.

Then, thinking of something, Yang Song unbuttoned the shirt of the corpse and looked at their bare chests.

As expected, there was a line of scar at the center of the chest near the heart area.

"What a cruel place. If every member is attached with a chip on their heart, wouldn't it mean that they can do nothing other than obeying the orders of their leader?"

The way that this place controlled its own people was simply super practical, but it was way too cruel and inhumane at the same time.

With just one button, the leader could decide the life and death of his own employees.

But here came another question, "But just who was so cruel enough to have the heart to kill all these people?"

Looking roughly at the hallway, Yang Song estimated that there should be more than seventy corpses, plus the ones in the various rooms, there should be nearly two hundred corpses. However, this secret base was so big, so how many people were killed?

Yang Song soon walked along the hallway and scanned the identity and entered a room.

This room was white in color and it was very spacious. However, the things stored in this room could be said to be "pitch black" and void of humanity.

Around the room, there were many vertical cryogenic hibernation capsules with cyan liquid contained inside. And other than the cyan liquid, what was contained inside those capsules were varied in types, they were basically humans and animals.

For the humans, it went from little baby to a very old person. Some babies had their limbs separated, some babies had their hearts on the outside and their four limbs were all adult limbs instead of baby limbs, which looked extremely terrifying.

Some adult corpses had their hands cut off and were replaced with plants and other kinds of organic creatures.

Some old corpses had their heads cut off and were replaced with animal heads that looked just like monsters.

And facing the inner entrance of the room was another door. Yang Song simply opened the door and found an even more disgusting and weird things.

There were several big dissecting tables stained with messy blood. And on each table, there were several weird-looking human corpses. Those corpses all hand animal heads. But their chests were still open wide.

Yang Song walked over with a wrinkled face and prevented the urge of wanting to vomit.

"The heart again?" When Yang Song saw the situation inside the body of that certain corpse, he was once again startled. This corpse's body was being cut open for the purpose of wanting to plant something on the heart.

But why did they do that? The answer to this question was cleared in an instant when Yang Song's eyes fell on the fingers of this corpse.

This corpse had a big head of the wolf and a body of a human. His two arms were two times thicker than normal, but they did not seem to contain any fat at all. On the contrary, those arms seemed to be full of explosive and powerful strength.

Yang Song's eyes then further rested on the fingers of this wolf-headed corpse. Each finger simply had a sharp pointy and thick fingernail which looked no different from a wolf claw. Each claw looked so sharp to the point that it made Yang Song felt that a touch was enough to penetrate a plate of steel.

Yang Song then went to another corpse. This corpse had an eagle head. His arms were equally as thick as the earlier corpse's arms but this corpse only had three fingers or simply three claws on each side. Even his legs were no different from the legs of the eagle.

Another corpse near that had a human head, but his body looked very awful and unbearable. It was simply covered with many eyes of various animals and even the eyes of the abyssal beasts.

After looking around a bit more, Yang Song took out his phone and took many pictures of this place.

Yang Song then walked around the room and stretched out his hand, wanting to collect some technological devices. But he retracted his hand suddenly.

"What if these things have GPS installed in them? If it really is then troubles would come knocking my door in the future if I were really to take them away."

Before knowing the exact situation and information about this secret base, Yang Song did not want to damage anything or take away anything.

After leaving this hellish room, Yang Song walked on the hallway again and arrived at another room.

Inside this room, there were many big boxes made of steel and were locked with super thick chains. But it was not a problem for Yang Song. He first looked left and right, and after determining that there were no suspicious things around, he took out the Blue Bolt Sword and slashed it with a swish.

The chains were cut off like tofu. Yang Song pulled open the door of the box and looked at what was inside.

But when he saw it, he only let out a smile. Every man had a dream of holding guns, and seeing so many guns and rifles in this box, Yang Song could not help smiling.

He had to admit that some guns and rifles were useless against him now, but that was in the premise that he was prepared beforehand. If he were to face so many guns and rifles all at once, even a Foundation Building Realm cultivator like him had no hope of surviving.
