The roar was low, like the wail before the earth trembles, like the lament of this world, giving people a strong feeling of melancholy.

If, as Lao Song said, the deep well is an infinitely extended space, then the sound that can escape from the deep well is definitely not just sound.

The moment he realized this, Lu Ban felt something brewing in his body.

When he heard the roar, the pollution had already touched him!

But Lu Ban only felt some white hair growing on the back of his hand, but no deeper erosion occurred.

With a gentle tap, the white hair will fall off, just like the floating hair on a cat's body in spring.

This is somewhat unreasonable, because the pollution that can escape from the deep well cannot be of low level, but high level pollution will not just make Lu Ban grow some white hair and be done with it.

He and Xia looked at each other. Xia seemed to be affected to some extent, but it was still within an acceptable range.

I think it’s because of this outfit.

Lu Ban looked at the yellow protective suit on his body.

This set of clothes' ability to isolate pollution is stronger than he imagined.

He saw that the ground was changing due to the vibration of the sound. The stones began to split and white fluff grew from the cross-section. The fluff kept swaying and wriggling, and soon turned the stones into a sticky gray semi-solid state, like undried cement.

Lu Ban felt that this thing looked a little familiar, but before he could establish a connection with these mutated stones, the ground beneath their feet became muddy, and countless cement flowed up along the giants' feet, trying to swallow them up.

Da da da——

Lu Ban heard that the equipment on the giants made continuous crisp sounds, like the countdown of a bomb, which made people suddenly feel nervous.

The others tried hard to keep themselves steady, but Lao Song silently took out a short, thick stick from the backpack behind him.

The stick was similar to a flashlight, but without the bulb, and had a smooth, black surface.

Lao Song inserted the stick into the ground which was as soft as a mouth, and the greedy mud immediately submerged it, just like a child who had been hungry for several days wolfing down his food without even bothering to see what he was eating.

The next moment, the quagmire suddenly trembled, and ripples appeared on the thick gray mud on the surface. Then, with Lao Song as the center, the mud and water escaped and formed a strange open space.

The black stick fell to the ground and was also shaking slightly, as if it had released some kind of high-frequency signal, dispersing the mutated stones.

Old Song picked up the stick and could see that as the stick moved, the mud and water also moved, forming a circular area.

"Let's go."

Old Song held the stick tightly and continued moving towards the deep well.

Da, da, da——

The intervals between the counting sounds of the equipment lengthened again. Although they were much more frequent than when they first entered the forest, they were still not as continuous as when everyone was wrapped in mud before.

As he moved forward, Lao Song took out a real flashlight from the box containing the equipment.

The flashlight looked ordinary, and its shape was no different from the tools Lu Ban knew.

But since it is a flashlight from the Brilliant Realm, there must be some difference.

"What is this thing?"

Lu Ban then asked Lao Song and pointed to the flashlight in his hand.

“It’s a flashlight.”

Old Song answered simply.

“It can illuminate a certain range of space. In a deep well, most areas are quite dark, and you need a flashlight to find the direction to go.”

"…I mean, it doesn't have any anti-pollution properties?"

Lu Ban asked.

"Isn't it enough to bring us light?"

Old Song asked back.

"That's right!"

Lu Ban nodded in agreement.

Xia looked at Lu Ban with a strange look in her eyes.

"Be careful, Shenjing is not a good place for tourism."

Old Song reminded.

They had now reached the edge of the deep well.

The dividing line of the world.

When Lu Ban saw the pitch-black space in front of him, this thought came to his mind.

This deep well has no clear boundaries. The front seems to be shrouded in a thin layer of fog, ambiguous and chaotic, as if it can swallow and contain everything.

It was extremely quiet in front, and Lu Ban had some imagination. He was afraid that even if a stone was thrown in, it would not cause any waves.

But the deep well also contains a surging power, the most obvious of which is the dark crimson that is faintly visible in the twilight-like black fog. Those colors penetrate the boundaries and give people a strange impression.

The light shone on Lu Ban, and he found that his skin was gradually growing some black, short, thick and hard hair. He scratched it through his clothes, and the hair showed no signs of falling off, as if it had already stuck to his skin.

It seems that this light is more polluting to the body.

However, he did not have more time to observe carefully, because the giants had come to the edge of the black fog. They left two people outside to guard the equipment, and the rest of them each took a flashlight and a walking stick and then walked into the black fog.

Lu Ban initially thought that according to Lao Song’s description, the deep well should be similar to a black hole, with a strong gravitational force, and people might even be distorted if they got close to it.

But from his perspective, nothing like that happened.

They walked into the deep well as if they were taking a stroll.

Lu Ban saw that the world suddenly became cold and the surroundings were shrouded in darkness. This darkness was not the darkness of the night, but pure darkness, a darkness that might even cast doubt on his own existence.

Lu Ban couldn't even feel the presence of the giant holding him up.

There is a theory that discusses the impact of vision on human perception. The experiment is very simple. It is to cover one of the subject's arms with something and place a fake hand next to his hand. The subject is asked to observe by constantly stimulating the fake hand. Eventually, his arm will respond to the stimulation of the fake hand, as if the fake hand has become a real hand.

Therefore, when humans fall into this absolute darkness, other senses will be affected accordingly.

Moreover, this is not simply darkness, but an infinitely extending space.

The pollution contained in it is enough to torture people's rationality, causing them to have all kinds of hallucinations and even doubt their own existence. In such a polluted environment, the loss of rationality will lead to even more terrible situations.

Until a light came on.

The light came from the flashlight in Lao Song's hand.

Artificial light has never been as warm as it is at this moment. With a few rays of light, Lu Ban was able to see the environment here clearly.
