This time he infiltrated, Zheng Fang did not choose the place where he was suspected of being the lord of the four countries before, but went directly to the modern three-story building.

The reason is very simple, when Zheng Fang arrived at that place and saw the situation inside, he could clearly understand what the situation was inside, and if it was the real location of the lord of the four countries, he could also know it at the first time.

If there are other important things, Zheng Fang will naturally be more interested, after all, the things that the Blood Sacrifice Alliance does often bring a lot of surprises to Zheng Fang.

For example, the previous Bomb Corps, although it was said that the Blood Sacrifice Alliance engaged in this project of transforming people, which was quite inhumane, but it also made Zheng Fang understand a lot of their development ideas, if there was no previous experience, Zheng Fang was afraid that when he was in the general command post before, it would be difficult to see why those soldiers of the Blood Sacrifice Alliance could not be afraid of the attack of guns and bullets.

"This is it. ”

Coming to the modern building, Zheng Fang calmed down and began to wait quietly.

In about fifteen minutes, Zheng Fang waited for a team of people to come out of it and stabilize his mentality, Zheng Fang waited for another team, and the interval between the front and back was twenty minutes.

That is to say, at the entrance of the building, every twenty minutes, a patrol will come out of it, and this patrol, after going around the building, will circulate again through the back door of the building.

Although he didn't know the situation inside the building yet, Zheng Fang could roughly judge the distance inside according to their speed, and in twenty minutes, they could walk around.

In this way, there may not be any big tricks in this building.

In fact, Zheng Fang also had a guess before, whether this would be the factory where the Blood Alliance made bomb soldiers.

To be honest, on the frontal battlefield, if the number of bomb soldiers is large enough, it can actually inflict a devastating blow on the soldiers of the Great Yuan Dynasty.

After all, such a freely movable C explosive package, once one or two broke through to the front line and detonated, it could bring several times or even dozens of times the battle damage to the Great Yuan Dynasty, how could Zheng Fang not guard against it?

It's a pity that the current Sand Country is in the hands of the Blood Sacrifice Alliance, and Zheng Fang can't launch a large-scale attack

to unleash the forces of the Blood Alliance.

Now there should be a lot of transformation factories in the hands of the Blood Sacrifice Alliance, which Zheng Fang can basically confirm, but the possibility that this place is a transformation factory is actually not big in Zheng Fang's opinion.

The reason is very simple, after all, it is a soldier who makes a bag of C explosives, there is no need to do it behind the main hall of the Shacheng Imperial Palace, right? Even if all the money from his blood sacrifice alliance is robbed, then there is no need to dare to do such a stupid thing.

When a patrol team passed, Zheng Fang quickly emerged from the darkness and ran towards the gate of the building.

After coming in, it was a hall, and there was no one standing guard around, and even the lights were dim, that is, Zheng Fang's eyesight was relatively strong, otherwise he wouldn't even be able to see things clearly after coming in.

Such an arrangement shows that this hall is not really a key location.

Thinking of this, Zheng Fang continued to explore inside, and soon, he followed the corridor behind the hall to an elevator.

"This ......"

Zheng Fang was embarrassed, such an arrangement, in fact, Zheng Fang did not expect, if the connection between the top and bottom here, there is only such a way as taking the elevator, then Zheng Fang's so-called infiltration has become a joke.

Just kidding, in such a small space in the elevator car, Zheng Fang can't hide his figure unless he knows how to stealth, and people only need the most ordinary monitor to make Zheng Fang clear.

After thinking for nearly a minute, Zheng Fang turned around and went back.

"Then there is only one option left. ”

The elevator of the building, Zheng Fang must not be able to enter, fortunately, when Zheng Fang came over, he noticed the ventilation duct of the building, according to his memory, Zheng Fang found the entrance of a ventilation duct, took out a dagger he carried, quickly unscrewed the screw, and Zheng Fang drilled in.

"Ahem......"

Just when Zheng Fang had just drilled into the ventilation duct, a coughing sound came from the direction of the elevator, making Zheng Fang frown on the spot.

"Was it discovered?"

Zheng Fang maintained his previous posture at the moment, motionless, while his ears were full

I listened intently to the movement outside.

After the coughing sound passed, Zheng Yi heard a sound of neat footsteps about fifty meters away, according to Zheng Fang's experience, it should be a movement made by a patrol team.

From the feedback of the footsteps, Zheng Fang heard some information, first of all, they still moved unhurriedly, indicating that it was really just a member of the patrol who coughed, and did not find Zheng Fang.

Holding his breath, Zheng Fang waited until this group passed before he breathed a sigh of relief.

Speaking of which, Zheng Fang was really not afraid of being discovered by them, not to mention this little patrol, even if it really alarmed all the guards in the Imperial City of Shacheng, they didn't see the dog stop Zheng Fang from leaving, but Zheng Fang really didn't want to see that kind of situation.

Once he is discovered, after he startles the snake, the follow-up actions of the holy knife will increase a lot of resistance, and when the time comes, it will affect the key action of snatching the lord of the four countries, and Zheng Fang will regret it.

When they walked away, Zheng Fang acted again, followed the ventilation duct, and climbed towards the elevator entrance of this building, and soon, Zheng Yi appeared above the elevator of this building.

Because it was late at night, there were not many people using this elevator now, Zheng Fang followed the elevator and climbed to the second floor, because he didn't know the situation outside the elevator, Zheng Fang didn't dare to go out directly, but repeated the old trick, continued to drill the ventilation duct on the second floor, and left the elevator shaft.

After coming out, Zheng Fang found a gap and began to look outside.

"It's not a factory. ”

After seeing the scene outside, Zheng Fang said secretly in his heart.

The place on the second floor is obviously much brighter than the first floor, and there are some huge bottles and cans displayed everywhere here, not so much a factory, but a laboratory, and after carefully looking at those bottles and cans, a person suddenly appeared in Zheng Fang's mind.

"Could it be that the Western Regions poison doctor has set up a laboratory for himself here?"

With such an idea, Zheng Fang sped up his movements, and after confirming that the second floor was indeed just a similar laboratory warehouse, Zheng Fang returned to the elevator shaft and went up again, to the top floor of the three-story building.
