Shi Yan's head was running at high speed, thinking about a way to get out, there was no other way but to try it like this.

Without waiting for the black shadow to come in front of him, a stream of red mist erupted from Shi Yanmei's heart, and the red mist seemed to be slow and fast, quickly enveloping itself.

Shi Yan released the red mist only because in the gray mist last time, the red mist helped him avoid the detection of the three-headed cat.

So he also became a dead horse doctor, whether he was useful or not, let it out first.

Who knew that as soon as the red mist came out, it met the cold jet black on the skin, and it made a sizzling sound, and the jet black was disappearing at a speed visible to the naked eye.

Before Shi Yan could be happy, the black shadow with long hair and covering his face had already arrived, and a miserable white and slender hand pressed towards Shi Yan.

It seemed to be very slow, but it was actually very fast, and Shi Yan had just had time to raise his hands to protect his front, and that hand had already reached into the red mist.

The red mist suddenly rolled up, enveloping the hand at once, and spreading upwards along the hand, as if it was about to sweep through the black shadow's body.

Shi Yan was taken aback, it was the first time he had reacted so excitedly when he saw Red Mist.

The black shadow screamed violently, and jerked his hand out of the red mist, and the arm was corroded to a pulp.

The black shadow turned around and ran, Shi Yan was willing to let him go, and blasted at him with a punch.

But the shadow was fast, turning into a puff of black smoke and disappearing into the walls.

As the black smoke dissipated, the scenery in front of me changed, and now where is it still in the corridor?

Obviously on the rooftop of the top floor, even a few meters away from the edge.

Shi Yan broke out in a cold sweat, when did I get to the rooftop, wouldn't I fall downstairs after a few more steps?

Although the body is strengthened, it is still unknown whether it will be able to withstand this height, and what if the head hits the ground?

At this time, the red mist was still around, and the blackness and coldness on his body had completely disappeared.

Looking at the red mist outside his body, Shi Yan also had an idea, thinking that the red mist seemed to have some effect in the gray mist, so he released the red mist, but he didn't think that he could force the black shadow back.

"Why can you scare the dark shadow away?" Shi Yan asked the system a little strangely.

"Because it's my food, it's a pity to let it run, otherwise it's another big meal." There was longing in the system's voice.

"A big meal? Is it your big meal? What kind of monster is that Black Shadow? Shi Yan remembered being left by that white and slender hand, and the black left on his body.

"I don't know what you call it, I just know that I want to devour it." There seems to be a swallowing sound, is this a delusion?

"Is it good for me that you devour him?"

"Of course there is, whatever is good for me will be good for you."

In this way, it is very interesting, Shi Yan couldn't help but groan for a while, but Shi Yan still decided to understand it first and then talk about it, because it is too weird here, so it is better to be careful.

Shi Yan looked around for a while, but there was no one, and the roof of the old building was empty.

Walking downstairs, it was pitch black, the lights that had been used to come up were gone, the clean walls that I had seen were now dirty and covered with graffiti, and the neat corridors I had just seen were covered with dust and debris.

Everything has changed, and what I saw was all unreal.

Walking to the first floor, only the street lamp in front of the gate is real, and it still emits dim light.

Who is this dark shadow? Could it be a woman in a suit? However, Shi Yan instinctively felt that it was not, but now he didn't know where the woman in the suit had gone.

When Shi Yan thought of this, he couldn't help but think of letting his digestive system swallow the gray mist at that time, but he hadn't seen it say anything to himself until now.

"How did you digest the gray fog at that time?" Shi Yan asked directly about the digestive system.

"It's a very pure, high-level energy, it's hard to break it down again, and if you insist on digesting it, it will take a long time." The system sound sounds.

"Oh? How long will it take? Shi Yan asked casually.

"8624 years to be exact."

"What?" Shi Yan was taken aback, it would take a while to systematically decompose and refine the blood of the monster, and it would take thousands of years to decompose the gray mist? Why is the gap so big?

Shi Yan was silent for a while, and then said, "Check if there is any gray fog in this red brick building?" ”

Red mist overflowed from Shi Yan's eyebrows, and soon filled Shi Yan's surroundings again.

After a while, the red mist converged and returned to Shi Yan's eyebrows.

"There is an energy existence similar to the gray fog, but it is lighter, more complicated, and not so advanced than the gray fog."

There is actually an energy similar to the gray mist in the small building? This is strange, the gray fog has just appeared, and Xiaolou has been around for many years, what kind of relationship are they?

In another twelve days, he will be fed, and if he wants to capture the monster, he will enter the gray mist, and if he still has a black eye in the gray fog like last time, let alone hunting monsters, it will be a miracle not to die.

He had to hurry, after all, no one could guarantee that he would be able to hunt monsters as soon as he entered the gray mist, and no one knew how many days it would take to hunt monsters in the gray mist.

Although he had killed the Komodoro Leopard, it was without the influence of the gray mist, and if he entered the gray fog now, he was not sure if he would be able to find the monster in ten days.

Not only him, it seems that the awakened people inside are also trapped, otherwise someone should have escaped a long time ago.

Three days later at the latest, enter the gray fog to hunt monsters, and it can't be too late.

If possible, he would like to leave sooner, so that there is enough time, and hopefully he will find a way to deal with the gray fog in the next two days.

"Is there any way to detect the existence of these similar energies in advance?" Shi Yan asked.

Shi Yan didn't find anything abnormal when he first entered the red brick building, so he caught the strange shadow of the long-haired and one-eyed man, if he found something wrong at the beginning, maybe the result would be different.

"You can continuously turn on the lowest level of digestion function, and there will be no red mist, but it can slightly decompose the material components around you, which is the best for detection."

Shi Yan didn't even think about it and said, "Okay, open the lowest level of digestive function." ”

"Okay, it's already opened, but it's not a small drain on energy if it's kept open."

"Oh, how much energy is consumed?" Shi Yan asked.

"One unit card is needed per hour, and one card equals 10,000 energy."

Shi Yan calculated in his heart, he needed 240,000 energy a day? So much, he remembered that the digestive system absorbs energy in the hundreds at most and dozens at the least, and it is difficult to reach hundreds of thousands of energy.

"How much energy do you have now? How much can I absorb in a day? ”

"Now the total energy is 678563, and I can absorb tens of thousands of scattered energy a day."

Shi Yan frowned, so little? He asked, "How can I speed up energy absorption?" ”

"Like the last time I angered a group of monsters, the energy absorption increased significantly, and in just over an hour, nearly a million energy was absorbed."

Uh, it turns out that if you want to provoke others to absorb energy, you can absorb it quickly? Shi Yan couldn't help but scratch his head speechlessly.

Could it be that in the future, I can only be hated by others, and hated by people when I see flowers blooming?

Shi Yan wrote down the address, and then went back to his rented room.
