Ten minutes later, I slipped out of the building alone, sneaked in, and found an open area.

This location is in the southeast corner of the city, which is a relatively secluded area in terms of the city, and it is quite far away from the imperial palace in the central area of the city.

It is a construction site under construction, the basic silent workmanship of various large machinery, and the ghosts who control the machinery are wearing dark overalls, moving fast and steady, and they are familiar with it.

It can be seen that mechanization is quite popular in the small world, and its efficiency is more high-end than that of the original world.

I infiltrated an unfinished building, and at this time, no ghosts were found in the building.

After a few minutes of 'agitation' inside, he quietly left, and then, hiding aside and chanting spells and pinching his hands, after all this was done, he crushed the red talisman in his palm.

Only I could hear a soft 'buzz', and then, the building in the middle of the site was covered by a magic circle.

That's right, I sneaked in and hid a few red talismans as array eyes, and set up a simple magic circle.

Due to the interference of the remote control of the mind, you can only use a stupid way to urge remotely, that is, to reserve a red talisman for urging action, and crush the red talisman after reciting the spell, and the formation will naturally be activated, which is not bothered by terrible gravity.

After the circle was successfully driven, I silently counted in my heart.

"One, two, three......, twenty-six......, thirty-three......." At the same time, let go of your senses and feel the changes in the 'yin current' in the air.

These ubiquitous Yin airflows like tentacles are the unique monitoring methods of the Yin Rhino Country, which are all over the country, but they are just the difference between the coverage density and the reaction speed, this is the national capital, the density is the largest, and the response is the fastest.

When I counted the seconds to 'forty', the yin air flow had already detected an abnormality, and it was trapped directly towards the layers where the magic circle was, and at the same time, a sharp sound suddenly sounded, and the movement was like the sound of countless metal and tempered glass rubbing against it, which sounded so harsh and uncomfortable!

This is the alarm sound that belongs to the capital, and in the moment of this movement, the ghosts working on the construction site shouted in horror and immediately fled from their posts.

I could perceive that the sound was sent in a straight line in the direction of the palace, covering only the area where the sound passed in a straight line, and the other areas would not be alerted by the alarm, so as not to disturb the whole city.

After all, as long as the alarm is transmitted to the guard corps, the mission is completed, and there is no need to make the whole city panic.

I continued for a few seconds, but it was only six seconds, and fifteen hoverboats flew in like lightning, and then floated there around the unfinished building.

Then, in twenty seconds, thousands of heavily armed guards poured around the construction site.

They were still dressed like that, with swords on their backs and crossbows in their hands, as if they could wipe out the invaders at any moment.

"From the urging of the magic circle to the arrival of the levitating boat and the guard corps, it took a minute and six seconds."

I came to conclusions on the spot, turned around and left.

The other party will definitely break the magic circle, and at that time, only the ashes of the burning talisman will remain.......

I came out alone to get the data on the reaction speed of the capital guard corps when it was in battle, and at this moment, I knew it in my heart.

The magic circle arranged by the red talisman for the eye of the array could only last for forty seconds before it was searched by the Yin Qi current.

Then, the magic circle arranged by the purple rune for the eye of the array is much more concealed than that of the red rune, and it should be able to increase the time by about ten times, that is, the time of four hundred seconds.

About six minutes and forty seconds to be exact.

It takes six seconds for the levitating boat to fly to the most corner of the capital, which means that using the purple talisman as a formation eye to arrange the trapped formation can find a gap of six minutes and forty-six seconds at most.

Considering the speed of the hoverboat, the last forty seconds or so should be the time for our safe evacuation, so the effective time that can be used is only six minutes at most.

The single power of the golden rune has surpassed the level of the purple-clothed ghost, so it is impossible to use the golden rune as a formation eye, and it is even more impossible to use the black rune.

When I returned to the building and told the female ghosts waiting there about the results, everyone was silent for a long time.

After half a ring, Xiaoxian said: "If you don't use the magic circle to trap the enemy and attack the target directly in the capital, then, the energy fluctuation will be transmitted immediately, and in six seconds, the levitating boat will surround us, right?" ”

"That's what it means." I nodded.

At the beginning, we were lucky, thinking that there might be a gap in the Yin air flow that could not be covered, and it was impossible to attack the target in the area that was not scanned, and we didn't even need to set up the magic circle in advance, just quickly eliminate the guards and capture the target.

But after I experimented with it, I realized that we were taking it for granted.

Maybe there can be a zone outside the capital where the yin air flow control is weak, but there are absolutely no dead ends in the capital, the yin air flow is all covered, and the density is extremely high, so it is particularly difficult to capture the high-level guards in the capital.

It is estimated that in a short period of time, the high-level officials of the Guard Corps Headquarters who come out to work should not leave the capital, and we have no time to wait for the high-level ghosts to go out of the city to work, and we have to do it if we catch a suitable target, so the possibility of acting in the capital of the Yin Rhino Kingdom is as high as more than seventy percent.

"There is only a six-second buffer time to act in the four sides of the Sacrificial City, if you do it directly in front of the palace and the headquarters of the Guard Corps, then, at most, it will only take one second, and you will be locked and surrounded by multiple suspension boats, and if you can't break the seal at this moment, you will inevitably be captured alive."

I added a little more.

Xiaoxian and several female ghosts glanced at each other and frowned at the same time.

Fang Rou walked left and right, and suddenly said: "Senior brother, then we can only take the risk of acting in the city, we have to wait, senior uncle and senior sister can't afford to wait, perhaps, one second in advance, we can rescue people, if we are one second late, ......?" ”

The little junior sister didn't finish speaking, but everyone understood what she meant.

"Then let's do it, we must capture the target alive and kill most of the guards around him within six minutes, our Dao is suppressed, and the attack power is far less than before, but only the strength of the body is far from being comparable to those purple-clothed ghosts, they are all faster, the obstacle will be cleared, and then, catch the target, and get out of the sacrificial city as soon as possible."

"Outside the city, there are always void areas that cannot be covered by the Yin airflow, and the 'target' of interrogation there is ......."

I ordered it on the spot.

"Understood, that's it." The little fairies all responded in silence.

"Senior brother, will you elevate me to the level of a purple-clothed ghost?" Fang Rou looked up, I nodded knowingly, and threw Fang Rou a few Dark Crystals, and the junior sister immediately ran a unique secret technique, first arranging a small force field to control the Dark Crystal, and then, shattering the Dark Crystal at high speed, absorbing the energy inside.

This process is so fast that even the Yin air flow is imperceptible.

A few minutes later, Senior Sister's Dao Xing was forcibly raised to the level of a purple-clothed ghost, and the white robe on her body turned purple.

Fang Rou skillfully ran the spell to suppress the breath fluctuations in the body, avoiding attracting the attention of the Yin Qi flow.

"Let's wait here for the rabbit, keep an eye on the gate of the guard regiment, once a high-level person appears, immediately follow, no matter where he goes, take it as a hunting target, preemptively bury the purple talisman on the road he must pass, and when he passes, he will urge the formation to trap him, and then, it will be six minutes of fierce fighting."

"Xiao Xian, don't form a ghost path three-talent array first, they are all purple-clothed ghosts, once the ghost path three-talent array is formed, you will immediately have the combat power of a half-step ghost king or even close to the ghost king level, at present, although you know that the strength of a single body exceeding the level of a purple-clothed ghost will lead to a catastrophe, but after all, it belongs to visitors from another space, this applies to the rules of local yin spirits, and it is unknown whether there will be any changes in the treatment of us outsiders."

"When can you be sure that the outsiders will join forces to attack, and the strength will not cause a catastrophe if the strength exceeds the level of the purple-clothed ghost, so you can use the Ghost Dao Three Talent Array at will. Now, with the purple-clothed ghost Dao Xing and the strength of the opponent's body, plus the six-minute shooting time, I think there is a good chance of success. ”

"Remember, once the six minutes are exhausted and you can't take the opponent, don't fall in love, run away immediately, as long as you go out of the city, the density of the Yin airflow coverage is not enough, it will be difficult for them to catch our traces......."

I talked about the battle plan in detail, and the four female ghosts listened with serious expressions and kept nodding.

"Brother Fang, there's movement over there." Jin Hena had been standing in front of the window to monitor the gate of the guard regiment, and suddenly reminded her.
