Speaking of energy, Xia Jian immediately took out a small leather bag from the pocket of his underwear.

The tether was opened, and an egg-sized one emitted a strange black halo in the sunlight, and a crystal as dazzling as a black gem appeared on Xia Jian's palm.

This is the general-level magic crystal he got when he killed the Black Corpse King......

Because it is hidden and very different from ordinary blood crystals, it looks like a black stone in the dark at first glance, and this magic crystal has escaped under the collection of Xiaoqiang and Dazhi.

"Discovering the ...... Absorbable Energy"

"Please determine whether to absorb ......"

Sure enough, Xia Jian heard the system prompt that he hadn't heard for a long time.

But can you absorb it or not?

You must know that this is an extremely special 'general-level magic crystal'!

Not only can it increase the chance of an evolutionary by 90%, but it also has a certain chance that an ordinary evolutionary will have an enhanced ability and enter the ranks of mutants.

"Alas......"

After hesitating for a while, Xia Jian finally sighed and took the magic crystal back.

It's not all because of reluctance!

If you absorb this magic crystal, you can fill the system with energy, and that's it!

But according to his predictions, this is absolutely impossible!

You must know that the last time he was promoted to the primary system, he had absorbed five 'general-level blood crystals'.

"It seems that the only way to go back ......"

Since he couldn't absorb this one, Xia Jian quickly thought of the box of blood crystals he had stored in the basement.

Although the quality of those blood crystals is not good, it is better than the quantity!

Filling up a few hundred of them will not be much worse than the energy provided by five 'general-level blood crystals'.

Until this time, Xia Jian had no idea that the box of blood crystals he had left in the basement had already stirred up earth-shattering waves in the settlement......

……………………………………

This man!!

You have to have a goal to be motivated!

This is not! As soon as he thought that he would return to the basement, he would probably be able to rise to level twenty and probably regain his previous strength.

He was originally sick, but he immediately became energetic!

If it weren't for the fact that it was too late, he would have even thought about flying back now.

Suffered all night......

Finally survived to the slightest amount of sky, and the dark chasers who were wandering in the shadow corners not far away had not completely retracted, Xia Jian couldn't wait to rush out of the room.

After confirming the direction, he plunged into the sewer pipe again.

……

However, this is not an area that Xia Jian is familiar with.

If you only wanted to run for your life before, you would have lost your way a long time ago......

What's more, the place where he wandered around was still in the labyrinthine sewer pipe.

By the time he found his way back to his familiar area, it was already two hours later.

Then on the way back, it took another two hours......

By the time he actually rushed back to the settlement, most of the day had passed.

……

The settlement was converted from an abandoned subway station.

Under the surface, all kinds of tunnels and pipelines extend in all directions, and Xiaozhu and others have opened up many new entrances and exits for convenience in the past, which has led to a lot of entrances and exits in the entire settlement.

But that's all in the past......

Now, in order to prevent the Dark Chasers and some mutated creatures from inadvertently sneaking in, most of the entrances and exits have been re-blocked.

There is only one main entrance and exit left.

On an empty street, Xia Jian walked over the manhole cover of an inconspicuous sewer pipe, picked up a random stone from the side, and knocked it twice on the manhole cover......

"Bell ......"

The iron manhole cover suddenly made a crisp sound of gold and stone crashing.

It didn't take long for a simple homemade periscope to peek out of the small hole in the middle of the manhole cover.

Xia Jian hurriedly put his face in front of the periscope camera, and by the way, he was still in front of the camera, making a few gestures that I wanted to go down......

This manhole cover is actually the main gate leading to the abandoned subway station......

There are no defenses.

There are no sentry posts either......

Some are just ordinary, inconspicuous manhole covers.

It seems incredible to say!!

Regardless of the fact that the street is very empty, there is no shelter or defense at all.

But this is actually the embodiment of the wisdom of the disadvantaged groups......

The surrounding area is empty, there is no shelter, and the chance of lurking the Shadow Chaser is low, even if one or two Shadow Chasers pass by occasionally, they will not stay for long, at most until the next day, they will definitely leave.

As for the defenses......

What do you want that thing for?

One head and two chasing the dark, everyone works together, and they will definitely be able to deal with it.

But if there are too many dark chasers, there are no strong people in the station, and there are no guns or anything, if you resist, you will die, so it is better to hurry up and run for your life.

"So long?"

Xia Jian suddenly frowned.

It's not once or twice that he's been in and out of this entrance.

Every time you identify yourself, in a minute or so, the person below will open the manhole cover.

But I don't know what's going on today, it's been almost five or six minutes, and the people below still haven't moved.

With doubts, Xia Jian picked up the corpse again and knocked on the manhole cover a few times......

"Bell ......"

This time he knocked harder than last time!

The crisp sound of the intersection of gold and stone suddenly reached the bottom of the manhole cover......

………………

The clock moved forward a little bit.

Or when Xia Jian knocked on the manhole cover for the first time......

Five people sat under the manhole cover, and one of them, a young man, was looking out for a while with his eyes on the periscope.

After recognizing that it was Xia Jian who was comparing in front of the periscope, the young man who was originally lazy and listless put his eyes on the lenses shook his whole body, and he wanted to be suddenly electrified, and the whole person came to his senses in an instant, and he gestured excitedly: "Yes...... It's that kid! ”

"Who?"

The young man's gaffe immediately aroused the dissatisfaction of the other four.

The man at the head reprimanded him impatiently: "Is there such a fuss about you? ”

"Yes...... It's ......"

Maybe it was because he was too excited, the young man was a little short circuited in his head for a while, and he couldn't explain it clearly, so he stomped his feet and lowered his throat and said, "Alas!! Brother Ming, you can see for yourself! ”

The man at the head, that is, Brother Ming in the mouth of the young man, hated that iron could not be steel, and gave the young man a white look.

"Xiao Zhang! It's not me saying you, calm down!! Be calm!! As you are now, what if you encounter a Dark Chaser in the future? Alas!! ”

Speaking of this, Brother Ming shook his head and sighed heavily.

Although he was very unhappy, he still stood up and took the periscope in Xiao Zhang's hand......

Well!! These chapters are a bit depressing! But it passed quickly......
