A few minutes later, Zhang Cheng ran to the front of the library, and when he saw that the door was empty and not locked, he was immediately happy.

It seems that Old Man Zhao was in a hurry just now, and he didn't have time to lock the door, God really help me!

Quietly pushing the door open a crack, Zhang Cheng glanced inside twice, and found that Su Xueqing was not there, and the entire library was empty.

Walked quickly to the iron door under the stairs, reached out and touched the position of the lock, the rust slag in one hand, the keyhole was blocked, it seemed that the only way to open it was to rely on brute force.

Thinking that behind the iron door was the source of yin qi, Zhang Cheng couldn't help but be a little excited, and no longer hesitated at the moment, his fingers grabbed the crack of the door hard, and the iron door suddenly made a piercing "rattle" sound.

"Click!"

The thumb-thick deadtongue was broken in two by Zhang Cheng, and the heavy iron door opened with a "creak", revealing a pitch-black space behind the door, and a cold wind mixed with a heavy musty smell blew out head-on.

"Holy!" Zhang Cheng shuddered, and a layer of goosebumps suddenly stirred up on his arm, and he felt that the room temperature of the entire library was a few degrees lower.

He is now a ghost corpse, although he has not lost consciousness because of yang energy, but his tolerance to heat and cold is much higher than before his death, this wind even makes him feel cold, if it is an ordinary person, it is estimated that he will be frozen directly.

Fortunately, after a few seconds, the cold began to dissipate, and there was no cold wind blowing out of the iron gate.

Zhang Cheng froze his mind, looked down, and could see step by step, extending all the way down, and after more than a dozen steps, it melted into a darkness, even with his eyesight, he couldn't see clearly.

Faced with everything unknown in front of him, Zhang Cheng suddenly became a little nervous.

Although he loves to read supernatural novels, as a flower that grows up under the red flag of the new era, he still classifies himself as a staunch materialist during his lifetime......

But now that he has this vivid example, he doesn't dare to think like that anymore.

How do you look at this basement in front of you, it's the beginning of those domestic horror movies!

But it's all here, so you can't retreat now, not to mention that you're half a ghost now, what are you really going to encounter...... Maybe you can make a new friend......

So Zhang Cheng gritted his teeth and walked in with courage......

The steps are still cement steps, probably because the basement is too wet, the surface is a little slippery, and the lime wall next to it is also very mottled, and a large piece of wall skin falls off when you touch it, and the air is filled with a strong musty smell, which is extremely pungent.

But Zhang Cheng didn't need to breathe at all, and he didn't feel anything.

Standing at the entrance of the stairs and looking around, he found that there was a lamp rope behind the iron door, but it broke into two with a slight tug, and he had to walk down in the dark.

After more than a dozen steps, there was a corner, and the light above couldn't shine down, Zhang Cheng thought about it, and felt that now was not the time to pick the door, so he concentrated the yang energy on the eyeballs, and the two eyes suddenly won a big victory, and finally could see the road below.

However, as soon as the Yang Qi was concentrated, the rest of his body lost its vitality, and his skin quickly turned pale, and dense purple corpse spots also appeared.

Zhang Cheng walked down the steps with green eyes in his eyes, and he was a fierce ghost traveling, if he was seen, he was afraid that he would be scared to death.

However, his image is quite compatible with the current environment.

All the way down, I walked more than a dozen steps, and the steps came to an end.

Zhang Cheng raised his eyes and found that the space below should be quite large, but there were all kinds of sundries and waste machines scattered together, and he couldn't see the whole picture.

The walls and ceilings are filled with re-damp groundwater, dripping down from time to time, making it particularly clear in the dark and silent environment.

"It's nothing special...... Zhang Cheng looked around, didn't find anything abnormal, and suddenly breathed a sigh of relief in his heart.

Twitching his nose slightly, he soon smelled the smell of yin qi, followed the smell all the way in, and after bypassing several half-human-high wooden boxes, he found a small pool made of cement at the end of the basement.

As soon as Zhang Cheng approached, he immediately concluded that the source of the yin qi was in the pool, but he did not act rashly, but carefully observed.

The pool is about two square meters square, and there is still water in it, but it is dark and you can't see how deep it is, a submersible pump is crooked in the middle, half of the water is exposed, and the iron case has rust through several holes, and it looks like it has been thrown in it for a long time.

Zhang Cheng stretched out his finger and carefully dipped a little of the water in the pool, only to feel cold and biting.

After hesitating for a moment, he stretched out the tip of his tongue and licked his fingers, and a trace of gray air suddenly flew out of his fingertips, drilling into the center of his eyebrows along the meridians.

It's really yin!

Zhang Cheng looked at the pool of black water in front of him and almost jumped up with excitement.

"Holy! This is a fortune! ”

Last time on the second floor, he only absorbed a little, and he had already benefited a lot, and now there is such a big pool in front of him, if he absorbs it all, then he will not go to heaven!

But...... The water in front of him is not slippery, and I don't know if I have soaked in a dead mouse, let him taste it, but if he really wants to drink it, he can't get it in his mouth.

But this didn't bother him, just now he had already discovered that the yin qi should be attached to the pool water, as long as he could find a way to strip the yin qi out, he didn't need to drink black water.

Zhang Cheng thought about it, simply lay on the edge of the pool, poked his face to a palm's distance from the water, and just wanted to take a breath, but the water surface was bubbling and bubbling.

As soon as he frowned, he didn't have time to take a closer look, when the water under his face suddenly opened, and a white hand suddenly stretched out from the water and quickly grabbed his face.

"I'll your grandma!" Fortunately, Zhang Cheng reacted quickly, and when he saw that something was wrong, he slammed his hands on the pool wall, and the whole person quickly fell backwards, "Bang!" With a bang, the back of his head slammed into a wooden box behind him, his head was fine, and the wooden box was shattered into slag.

Zhang Cheng got up with a bone, took more than a dozen steps back, and watched the white Huahua's arm slowly retract into the black water again, and couldn't help but swallow his saliva.

"What the hell ......?"

The arms disappeared and the water calmed down as if nothing had happened.

Zhang Cheng touched the top of his head with palpitations, although he hid quickly just now, the distance was too close, and he was caught off guard and still lost a few hairs.

At this time, the whole top of his head was slippery and greasy, and he reached out and touched a lump of something like spoiled lard, and when he looked closely, it seemed to be mixed with some fleshy nails......

Zhang Cheng tried to open his breath and smell it, and suddenly he rolled his eyes.

Go to Nima's! The socks that I haven't washed for three months aren't so smelly! Even if you are a ghost, you have to pay attention to hygiene!

He shook his hand again and again, rubbed the unidentified object against the wooden box next to him, found a ball of old newspaper and wiped his head vigorously, and then cautiously shouted towards the pool.

"Big brother, don't do it, your own people ......"

After shouting, there was no movement on the other side of the pool, but a woman's chuckle suddenly came from behind him.

"Giggle......

No way! There won't be another one......

Zhang Cheng's hips tightened instantly, and he hurriedly turned around, but there was nothing behind him......
