Xiao Yu saw an iron ball. When the corpse of the MSI civilization was accompanied by the somewhat frightened voice of the associated ghost clan, and escaped from the stellar circle of the small universe of the guardian civilization, Xiao Yu saw that the iron ball was chasing him closely behind the corpse of MSI. This iron ball was so amazing that Xiao Yu couldn't help but let out an exclamation.

This iron ball is simply an existence that Xiao Yu expected, Xiao Yu never thought that such a thing could exist in this universe. This is undoubtedly created through the superb technology of the Guardian Civilization, and after seeing this iron ball, Xiao Yu had an idea in his heart: "Perhaps, the Sweeper Civilization has never eliminated the Guardian Civilization, and this Iron Ball should occupy a large part of the reason." Presumably, this iron ball is the ultimate weapon of the Guardian Civilization against the Sweeper Civilization. It's just that before the Neutron Battlestar battled this iron ball, my MSI corpse arrived first. ”

This is indeed just an iron ball, which is mainly composed of iron, the heavy element with the largest reserves in the universe, and some other heavy elements are mixed with it. This is nothing surprising, but it is so large that it is twenty times the size of Jupiter, the largest planet in the solar system, and its density reaches an average of about eighty-seven grams per cubic centimeter. This density is about seventeen times the density of terrestrial planets like Earth. For comparison, Jupiter is only about a quarter as dense as Earth.

In other words, the iron ball is a solid planet, but it is twenty times larger than Jupiter.

It is absolutely impossible for such a star to exist naturally in the universe, but now that it appears here, then it can only be made by the Guardian civilization. The Guardian civilization has created such a star and placed it in its own small universe to use as the final hole card against the Neutron Warstar, now. was met by Xiao Yu.

The star has almost reached the limit of conventional material density, and Xiao Yu estimates that at its core, its density should be on the order of one kilogram per cubic centimeter. Although this density is still not worth mentioning compared to the density of the corpses of MSI civilizations, or the density of neutron battle stars, if the two collide violently, the situation is different.

The corpse of the MSI civilization can easily crash into a star without any damage, mainly because the density of the star is too low, so the corpse of MSI can unscrupulously hit it like a bullet through paper, but the corpse of MSI cannot hit this iron ball. And not only MSI corpses. Xiao Yu believed that even the Neutron Battle Star would not dare to hit this iron ball. Because the density of this iron ball is so high, it has almost reached the limit of the density of conventional matter. If you hit this iron ball, the MSI corpse or neutron battle star will not be destroyed, but it is certain. The monolithic structure of a neutron star, or MSI corpse. Stratigraphy and structure may be seriously affected. Xiao Yu can't estimate how serious it is, but in short, it's dangerous. Xiao Yu didn't dare to take this risk, Xiao Yu believed that the sweeper civilization also didn't dare to take this risk.

It is clear that the associated Ghost Clan is aware of this danger. That's why I fled in a panic. And for some reason, the speed of this iron ball is so high - and according to its mass and the space environment, it cannot be so high. Xiao Yu quickly thought of the reason, the Guardian Civilization had made some kind of transformation to the space of the small universe. The main reason for this transformation is to cooperate with the action of the iron ball, so that the iron ball can obtain a high movement speed.

"That's your final hole card, isn't it? Hmm......" Xiao Yu muttered to himself, "The holographic defense technology of the Radiance spaceship, the dense black lightning when it entered the small universe, and now, there is also this iron ball, as well as the unique space transformation technology inside the small universe,...... These four technologies were specially developed to deal with the Neutral Warrior of the Sweeper civilization, it seems that in these tens of millions of years, you have not been idle, you have tried every means to fight the Sweeper and have achieved certain achievements...... This iron ball is indeed very threatening, very threatening. ”

Xiao Yu can roughly guess the construction process of this iron ball. When building this iron ball, the guardian civilization must have searched for a lot of heavy elements from the universe, and then condensed them into a primitive planet core, and then, the guardian civilization took various advanced scientific and technological means to build various industrial facilities on the core of this planet, and then continued to add matter to the core of the planet, increasing its volume and mass, and after reaching a certain level, building industrial facilities again, and then covering again, just like that, layer by layer, layer by layer, layer by layer, layer by In the end, the iron ball was successfully built.

The Guardian civilization does not have the ability to construct inside a dense object, so they create a replica of the dense body themselves, and in the process of building the star, they also construct industrial facilities, such as propulsion equipment, energy reserves, weapon systems, defense systems, and other equipment.

Regarding the technological level and means of the guardian civilization, Xiao Yu is now completely impressed. Although the Guardian Civilization is Xiao Yu's enemy, Xiao Yu has to admire the Guardian Civilization. Because the Guardian civilization has really reached a limit, the limit within the scope of the sixth-level technological civilization. The Neutron Battle Star is the creation of the seventh-level civilization in the direction of the extreme star, and it is basically impossible to be confronted by the sixth-level civilization, but as the guardian civilization of the sixth-level civilization, it has found so many ways to fight against the Neutron Warstar within the scope of the sixth-level civilization.

Among them, the holographic defense technology can prevent the neutron battle star from wreaking havoc inside the radiant after hitting the inside of the radiant to a certain extent, black lightning can damage the neutron battle star to a certain extent, and the iron ball, although it is a one-time thing, can really threaten the neutron battle star. These measures are all formulated for the Cleaner Civilization, and the first person to try it was Xiao Yu.

"Ghosts, don't panic. Now you just have to do your best to dodge and not let the iron ball hit you. Although the mass and density of the iron ball are high, and the defense power is also very strong, there is a big gap between them and the real dense star. Let me destroy it with a regular fleet. Xiao Yu said.

The reality is so strange, it is in response to the sentence that one thing descends one thing. The MSI corpse is almost invincible to the regular fleet, but it is restrained by the iron ball, and the iron ball restrains the MSI corpse or neutron warstar, but it itself will be damaged by the regular fleet.

"It is unlikely that the regular fleet of the Sweeper civilization is the opponent of the Guardian civilization, then, after the Neutron Battlestar invades this small universe, the regular fleet of the Guardian civilization will suppress the regular fleet of the Sweeper civilization and prevent them from attacking the Iron Ball, and then the Iron Ball can chase and kill the Neutron Battlestar all the way. The Guardian civilization really has a good calculation. It's a pity, it's a pity, I'm not a sweeper civilization, although my fleet is not as good as your spaceship, there are too many of yours, how can it be so easy to suppress me in terms ......of a conventional fleet," Xiao Yu muttered to himself, and quickly made the next arrangement.

Since the start of the war with the Guardian Civilization, although many unexpected situations have occurred, the overall situation is still in Xiao Yu's hands. This time is no different. The iron ball was specially developed to deal with the Sweeper civilization, and now against Xiao Yu, although it can also hunt down MSI's corpse, but in terms of the conventional fleet, the guardian civilization can't suppress it.

Under Xiao Yu's control, a large number of spaceships began to gather together, and under the leadership of more than a hundred planet-level warships, they began to set off towards the front, and the target was the iron ball. After seeing Xiao Yu's movements, the Guardian Civilization also took emergency measures. Xiao Yu saw that the fleet of the Guardian Civilization also began to converge around the iron ball, and at the same time, a pale green light began to glow on the iron ball, getting brighter and brighter, and finally, this layer of light completely enveloped it.

Xiao Yu knew that the iron ball's protective system had been fully opened.

"It's not that easy, even if your ship is better than mine? I'd like to see how long you can hold up with my crowd tactics. Xiao Yu thought about it, manipulating the huge fleet and rushing to the side of the iron ball in an instant. The fleet of the Guardian civilization immediately began to fight back, and the melee immediately began.

MSI's corpse is still running for its life ahead. If you are hit by the Iron Orb, the Iron Ball will be destroyed - it is a disposable, but MSI's corpse will also be severely damaged. This deal is obviously not cost-effective for Xiao Yu. When the iron ball moves, Xiao Yu's attack fleet will also follow, and the defense fleet of the Guardian Civilization will naturally follow.

There were black spatial cracks everywhere, and the constant attacks of space weapons broke through the defense line of the Guardian Civilization Fleet and attacked the iron ball. At this time, the shield system on top of the iron ball will flicker, eliminating the attack invisibly. A large number of space weapons are also attacking Xiao Yu's fleet, and in the small universe, there are constantly spaceships disintegrating and exploding.

"It can't go on like this. If this continues, I don't know how long it will take to kill the iron ball. Late will change. Xiao Yu thought about it and made a decision again.

More than 100 planet-level warships instantly withdrew from the battlefield and began to move towards more than 100 specific points around the iron ball. Xiao Yu is about to use the space to smash and attack again. Seeing Xiao Yu's movements, the Guardian Civilization side also began an intensive military mobilization. (To be continued......)
