When the battleship base flew into Qingfeng Star, although it was a huge warship, as long as it was a pretext for some kind of exercise or the like, all the monitoring systems were turned off, and a sky ban was implemented, it only took a short time to be able to fly into the planet from outside the planet and hide, in this way, it was absolutely unaware, and the Qingfeng Star people would definitely not know that there was an extra secret base under their feet.

First of all, it is absolutely impossible for a battleship base to be hidden under land like this. If the battleship base wants to dive underground, it will cause great damage to the ground, leaving a huge hole in the ground, for example: when the battleship dives underground, it can separate the soil, and it can also restore the soil, but the vegetation on the surface and the abnormal situation of the soil cannot be concealed in any way. Therefore, all kinds of flaws can be covered up by various means, but such methods can only be concealed for a while, but they will definitely leak the news.

If it were Shi Qingzhi, if this was the base of the Yanhuang clan, Shi Qingzhi would definitely dive this base under the deepest seabed, and dive hundreds of kilometers underground, so that with thousands of kilometers of seawater and mud and stones as cover, it would never be possible to find out without the means to reach the sky.

But the Heavenly Tiger Empire is not the Yanhuang Clan, if they do this, their entry and exit will become very troublesome, after all, they are not like the Yanhuang Clan can use space to jump, so they will definitely leave an exit, and it is also convenient to transport all kinds of materials, so the location of the base can already be called.

Dive underwater, find a secluded place, and then, starting from the shore and going underground, and when you settle down, dig a tunnel from the ground to the surface, and then build a building company on it, and then, with the men of the secret department, act as the staff of this company, so that absolutely no one will suspect it.

Such a process will basically not leave any flaws, because, any traces will be covered by the sea, and no one will be idle to go to the remote water to find out, so that no one will find out about the secret base, as for the transportation of materials or something, it can be brought in by people through that passage, and the researchers in the underground base can also run to the ground from time to time to breathe, anyway, there are so many people in and out of a large company, and no one will doubt that there are so many more.

The coastline of Qingfeng Star is not long, but it is not small, it is enough for millions of kilometers, with the ability of Shi Qingzhi, it is more difficult to find the entire Qingfeng Star, but it is not so difficult to find the coastline, at most it can be found in a day or two, in fact, there is no need to look for it, you only need to find the traces left at that time.

There will be no flaws in diving underground from the coastline, but in the process of diving, because of the reason for diving underground, a large amount of soil will pollute the seawater, causing some abnormal situations, as long as you look up the ocean records on Qingfeng Star and find out what abnormal conditions occurred in the ocean of Qingfeng Star a hundred years ago, you can basically determine the location of the battleship base to dive into. It's just that this record may not exist, what Shi Qingzhi can imagine, the people of the Heavenly Tiger Empire will definitely want to get, and they may use their official power to delete all these materials, so there may not be any clues from this aspect.

It doesn't matter, you can run those materials, but the buildings on the ground can't always run away, this base has existed for more than a hundred years, and there will not be too many ancient buildings from a hundred years ago, as long as you find it, you can find it after another investigation.

Shi Qingzhi turned on his computer and began to search for century-old buildings on Qingfeng Star, close to the sea, cities that were not very developed a hundred years ago, there are not many such cities, since there are not many cities, there will naturally not be many ancient buildings in a hundred years, with these two conditions, it is easy to be able to filter out.

Found it, there are a total of three suspicious buildings, one is located in Donghai City, one is located in Baisha City Zhiling Building, one is located in Qinghe City, Qinghe Building, tomorrow I will go to these three cities to see the situation. After Shi Qingzhi got it done, he slept peacefully, he didn't dare to cultivate, in case someone found out, there would be trouble.

The next day, Shi Qingzhi began to visit the suspicious targets in these three major cities one by one, the first to go was the Mingwang Building, after three hours of Kamchatka, the Mingwang Building was not the target. The second one arrived at the Zhiling Building, and as soon as he entered the gate of the Zhiling Building, Shi Qingzhi felt that there was something wrong with the Zhiling Building.

First of all, in terms of building materials, the building materials used in the Zhiling Building are very good, much better than ordinary buildings, at least, the people who built here have used enough materials, if there are no accidents, the Zhiling Building can be used for at least 500 years, why should such an ordinary commercial building be built so strong? There is definitely a problem in this.

Secondly, there are also problems with the various energy transmission lines in the Zhiling Building, those energy transmission lines are hidden under the wall, of course outsiders can't see it, but how powerful is Shi Qingzhi's Yuan Shen? As long as you use the Yuan Shen to scan lightly, you can see that there is a problem with the energy transmission line under the wall, these energy transmission lines are hundreds of times stronger than ordinary energy transmission lines, which is absolutely unreasonable, after all, it is impossible for ordinary commercial buildings to install these high-level energy transmission lines that will only be used in military bases, because military bases need to install force field covers, so the energy transmission line is definitely much thicker than the general energy transmission line, and the upper limit of energy transmission that can be accommodated is much higher。 Everyone knows that the price of military supplies is several times higher than the price of civilian supplies, or even more than ten times, and the cost of building such a building and using military supplies and materials to build it is more than five times higher than the cost of using all civilian supplies.

Thirdly, there were hundreds of powerful energy fluctuations in the Zhiling Mansion, although these energy fluctuations were relatively hidden, but how could they be concealed from Shi Qingzhi? These energy fluctuations all showed the strength of the seventeenth level or above, and it was impossible for an ordinary building to have so many worship-level masters.

Comprehensive intelligence analysis in all aspects, Zhiling Mansion is the target he is looking for, however, before there is more evidence, Shi Qingzhi does not dare to draw conclusions, I remember Wu Tieliang taught him to say: "An excellent intelligence officer cannot only deduce intelligence by analyzing superficial phenomena, real intelligence must have enough evidence." A good piece of information can sometimes make the difference between life and death in a country. "There is a problem with the Zhiling Mansion, but before he finds the underground base for a day, Shi Qingzhi doesn't dare to draw the most serious conclusions, maybe this is the blinding method used by the Heavenly Tiger Empire, the purpose is to mislead intelligence officers like him.

Although Shi Qingzhi already has eight points to affirm that the Zhiling Mansion is the target, he still went to the Qinghe Mansion to take a look, the Qinghe Mansion is not particularly abnormal, it's just that there is also a little weird among them, there are also a group of masters in the Qinghe Mansion, although there are not too many, but there are seven or eight, and the others are not abnormal, what is going on?

If something goes wrong, there must be a demon, this is the law, there are two problematic places, which one is the main one? It is difficult for Shi Qingzhi to make a judgment, yes, it is better to go to the beach to find it, if you can find traces on the beach, you can prove that it is on that side.

After another day of going around the two seashores, Shi Qingzhi was sure that it should be in the Zhiling Building. The location is determined, but how to get in? This is another big problem, it is impossible to force a force into it, if the conjecture is true, the base below is a warship, even if this base battleship is not able to go to the battlefield, but its defense system and force field cover are placed there, with the strength of Shi Qingzhi, if you want to break through the defense of the force field cover head-on and enter the inside of the battleship, the possibility is basically zero. Also, he came to steal information, and only considered destroying this base if he couldn't steal it, so Shi Qingzhi's first choice had already given up the idea of attacking.

If the attack is not successful, then you have to find a way to blend in, according to his observation, it is basically impossible to get in, such an important base, its guards must be very strict, and, the staff in the building are basically knowledgeable, it is not easy to get through, even if you catch an internal scientific and technological personnel with the art of change, it is difficult to get in, God knows how many rechecked levels there are in the road, a poor preparation will be exposed, and it is not good to startle the snake.

It is absolutely impossible to enter the interior of the base without going through the passage of the Zhiling Building, there is absolutely only one exit to this base, and it is surrounded by the armor of the battleship, and the protection of the force field cover, if you want to get into it from other places, you don't have to think about it.

If it is discovered, it will have to face a large number of masters of the Heavenly Tiger Empire, there are hundreds of worship-level masters in the Zhiling Mansion, this is not a force that can be easily dealt with, once it is discovered, it will inevitably be a vicious battle. For the enshrinement-level masters of the Heavenly Tiger Empire, the Yanhuang clan has understood very well over the years, with a level like Shi Qingzhi, there is absolutely no problem with one enemy and ten, and it can be easily killed, if you can fight one against a hundred, that is another matter, those enshrinement-level masters have very poor exercises or something, but the strength is hard, and it is definitely not the best strategy to fight hard with them.

After a day of reconnaissance, Shi Qingzhi has not yet considered how to be able to sneak into the base, the designer of this base is very remarkable, there are no flaws, through a day of reconnaissance, he has basically figured out the interior of the Zhiling Building, the exit is on the east side of the fifth floor of the basement of the Zhiling Building, there, there are at least fifteen worship-level masters guarding, if there is no password and identity certificate to enter and exit, it is absolutely impossible to pass this level.

The interior of the Zhiling Mansion seems to be undefended, but there are countless reconnaissance equipment, which will defend the Zhiling Mansion without leakage, and any corner of the wind and grass can not be hidden from the guards, it is enough, if you want to enter, you have to find another way.

He has also used the Yuanshen scanning, but the building materials of the Tianhu Empire are very good, and there is a strong hindrance to the scanning of the Yuanshen, and he can no longer go deeper after scanning more than ten kilometers underground, which is really troublesome, it seems that he has to go underground to see what the real situation is.

Put all the things to be prepared into the space ring, Shi Qingzhi dived underground, dived towards the underground of the Zhiling Building, and used the earth escape method in the Five Elements Escape Method to sneak in, which is absolutely unaware of the ghosts, and the race that is not proficient in the Five Elements Escape Technique will never be discovered.
