The Celestial Tiger Empire's closest base to Silver Star is 150 million kilometers away, in a valley by a river. Han Wenzheng couldn't help sighing, the Winged Girl Clan didn't pay much attention to science and technology, and didn't even have a decent map, when Han Wenzheng asked them for a map, the Winged Girl just took out a piece of animal skin, and the animal skin couldn't be regarded as a map at all, Han Wenzheng almost couldn't read it, there was not even a scale on it, only some simple symbols, after seeing these things, Han Wenzheng understood that this time he was afraid that he really had to do it on his own.

Without the Winged Female Clan to follow, Han Wenzheng and Qiushui directly used the Earth Escape Method to go to this base of the Heavenly Tiger Empire in order to avoid the surveillance of the Heavenly Tiger Empire in the air, as for what the base is called, they don't know what the base is called, and if they use the Earth Escape Method to hurry, it will naturally not be able to get up quickly, and they can only advance millions of kilometers every day, at this speed, they will not want to reach that base within twenty days.

There are also countless Heavenly Tiger Empire checkpoints from the city of the Winged Maiden to the enemy's base, and these checkpoints are one every 100,000 kilometers, which are obviously for reconnaissance, and the existence of these checkpoints also brings some trouble for Han Wenzheng and his wife to infiltrate the enemy base, so they have to be careful.

Along the way, Han Qiu and the others were very careful, and when they came out at night to breathe, they also chose some caves to come out, otherwise they would never show up, and would rather be in the underground, however, there are also many mountains on the Winged Actress, and the caves can be said to be everywhere, so there is no problem when you rest at night.

It can't be blamed that Han Wenzheng and his wife are so careful, the technology of the Heavenly Tiger Empire is very developed, in addition to reconnaissance methods such as ground checkpoints and reconnaissance satellites in the air, there may be some reconnaissance techniques such as Nazi robots, those Nazi robots that are as small as dust can hide people's divine sense, maybe there are countless reconnaissance robots flying in the air, or reconnaissance equipment is installed in unknown places, these winged women don't know what to do, even if they see the people of the Heavenly Tiger Empire installing, the winged women don't know what the use of that thing isMaybe the Heavenly Tiger Empire still has some reconnaissance equipment specially researched for the powerful Winged Maiden? Everything should still be careful.

The protection forces sent by the Winged Female Clan are also not allowed to follow, although they are moving fast, but they cannot hide the reconnaissance methods of the Heavenly Tiger Empire, in case the target is exposed, it will not be good. However, Silver Star Yuechen sent twenty small forces to carry out normal patrols in the area around Silver Star City, and carried out devastating strikes against all the things of the Heavenly Tiger Empire, whether it was for reconnaissance or not, everything used by the Heavenly Tiger Empire was destroyed first, so that the protection troops sent by the Winged Maiden Clan could play a covering role on the bright side, as for the protective role, there was also a role, in case something happened, these troops would be able to rush to support, as for whether it could play a role, Silver Star Yuechen himself did not count in his heart.

Han Wenzheng and Qiushui in addition to rushing every day, but also remember the surrounding terrain, with the sense of scan the surrounding area, in their own brain to automatically generate a map, and then draw it when it is useful, this little thing is naturally not a problem for Han Wenzheng, there are many wars, drawing maps is naturally a good job, of course, there are any special minerals around, elixirs and the like, also write down first, and then you can collect them in the future, these things are very useful to the Yanhuang people.

Finally arrived at the periphery of the base, the patrol of the Tiger Empire is much stricter, the sky is flying everywhere the Tiger Empire's aircraft, these flying machines are very special, they are all used by individual soldiers, it is a skateboard-like thing under their feet, with four vents, which can make people standing on it move at high speed, this kind of individual aircraft can fly to an altitude of 5,000 kilometers, and can fly at a speed of 200 kilometers per second, the speed is very fast, although there is no combat effectiveness, but, for the clone soldiers of the Tiger Empire, they only need to provide them with high-speed movement。

On the ground, Han Wenzheng had already discovered more than 370 special observation posts, although there were too many equipment that he didn't understand, but it should be for observation, and it was basically impossible for such a tight observation post to sneak into the base from the ground.

On the ground, there are a large number of robots patrolling, such a thing that looks like a dog, has an electronic nose that is ten million times more sensitive than a dog, enough to distinguish all smells, and a special reconnaissance system, it can be said that nothing can hide from them, and the number of this robot dog is not one or two, but in 100,000, almost every hundred square meters there is one, all objects without an identification system will cause their warnings and attacks, don't underestimate these are just guys about the same size as ordinary dogs, but their combat effectiveness has reached level 11, and they must not be underestimated, The robot dog is more than 100,000 on the surface, but I don't know how many more people are in the dark, maybe one or two million, and the defense is really tight enough.

In addition to these things that are easier to find, there are many secrets, Han Wenzheng has not found them, or he may not be able to understand them if he sees them, there is no way, the knowledge of science and technology is insufficient, maybe that little grass is a reconnaissance machine, but the appearance looks like a small grass, but they don't know it, therefore, the two of them are very careful, and they use the earth escape technique to go deep, no longer just lurking in a place more than thirty meters deep.

This base is very large, more than 1,000 square kilometers in size, all around is steel, no, it shouldn't be said to be steel, it should be a very special alloy, this alloy Han Wenzheng doesn't know its proportions, let alone its composition, but this special alloy can block the scanning of the divine sense, even with Han Wenzheng's divine consciousness to pass through this alloy is very difficult, can block the alloy of the divine sense scanning, Han Wenzheng really hasn't encountered it, no wonder the situation inside these bases The Wing Nu clan doesn't understand, in the can't break through the ground defense and enter the base, it's not easy to detect the internal situation of the base, Fortunately, Han Wenzheng came to a position that was only more than twenty kilometers outside the base, although those alloys could block the scanning of the divine sense, but they could not block the scanning of the divine consciousness so closely, Han Wenzheng was able to scan the interior of the base with all his might.

The alloy city wall on the periphery is covered with countless batteries, a cannon with a door length of only about ten meters is facing the distance, these batteries are not small, each battery is as high as thirty meters, up to fifty meters wide, forming the shape of a huge pillbox, however, the materials used are the equipment level materials of the battleship, it can be said that with the strength of the armor on the periphery of these batteries, even the strength of level 25 may not be able to break through, strong enough, and the protection of the protective shield, in the time of war, these batteries do not need to care about the enemy's attack and fire with all their might。 The caliber of those cannons has reached about one meter, in addition to the main gun, there are three secondary guns, the caliber reaches 0.4 meters, the four cannons of the big three are light and heavy, and they can produce strong power in battle, according to Han Wenzheng's estimate, with the power of these cannons, the attack power is only afraid to reach more than 18 levels. Although it is not clear how these cannons work, it is certain that chemical energy such as gunpowder is definitely not used, but other energy, and looking at the construction of the forts, it is obvious that there is an energy supply system inside the forts, so these batteries may be able to bombard non-stop for several days without problems.

In addition to the fort, there are other weapons and equipment on the city wall, such as all kinds of things similar to missiles, Han Wenzheng has scanned these things, and his heart is a little chilled, these guys are not big, really not big, but the power is terrifying, and it is very scary, in contrast, Tianzhu is too far away, these things that are similar in appearance and function to missiles, their power has reached level 20, it can be said that even if Huang Xingyi Girl is hit, she will be injured, not to mention that there are special potions in the missile, so to speak, a Huang Xingyi Girl was hit by a missile, and if she does not die, she will lose her combat effectiveness and be capturedIn the base, there are hundreds of such missile launchers, and each wave is capable of launching thousands of such missiles. Before the correct name of this weapon was known, Han Wenzheng still called these things missiles.

Behind the city wall, there is also a large-caliber heavy artillery weapon, which is also similar to a cannon, but after the divine sense scanned their energy supply system and working system, Han Wenzheng knew that the role of this weapon is not for destruction, but for defense, it can be used to fire all kinds of special shells, and it can also be used to launch weapons such as frozen light, even with Han Wenzheng's current strength, without using the Four Spirits Guardian Flag to protect himself, he will be frozen after being hit by a cannon. As soon as these special heavy cannons are fired, the shells will be raised within a few kilometers around the landing point, and those whose strength is below level thirteen will be immediately frozen up, which is really a terrifying weapon.

In addition to these, there are countless various organs, such as nerve gas, etc., since these organs are Yellow Star-level Winged Girls have to shed their skins when they encounter them, the power is definitely not a joke, it can be said that it is definitely not so easy to attack a base head-on, these defensive facilities are too complete, it seems that the Heavenly Tiger Empire once let the Winged Female Clan destroy many bases, therefore, the defense of the base has been strengthened, just such a base, the Winged Female Clan did not dispatch 300,000 Yellow Star-level Wingfemale Warriors to break through。

Underground, Qiu Shui said, "Husband, the power of the weapons possessed by this Heavenly Tiger Empire is very great, it is really not easy for us to attack from the ground in the future." "If it's just the Winged Maidens attacking, of course we'll lose some men, but if we're attacking, it's a different story, and we'll wait until we get the information we want to know before we make a decision." After Han Wenzheng learned about this, he had already made a decision in his heart, and this base would not be difficult for him.

It is a very troublesome thing to enter such a base, coupled with the various anti-reconnaissance means all over the base, even if you enter, it is troublesome, and it is even more difficult to move freely in the base, even if Han Wenzheng has all kinds of immortal magic methods, it is not easy to enter the base to move freely, but it is another matter to get information.
