Just as the Conqueror Squad was preparing to descend into the three-dimensional universe, a new situation arose. Hu Yu lost contact with all the four-dimensional fleets in an instant. Not only was communication lost in the four-dimensional universe, but the fleets in the three-dimensional universe were also out of contact.
All four-dimensional communication was cut off. The fleets in the three-dimensional universe, whether they were next to Hu Yu or had left for more than a year to continue attacking the Giant General Civilization, were all out of contact. Hu Yu never expected this to happen. The loss of four-dimensional communication was equivalent to him becoming deaf and blind.
Even Hu Yu doesn't know whether the warships controlled by these Superintelligent Robot will continue to complete their missions according to instructions or return to rendezvous with him. In the past, when the fleet's communications were cut off during battles, the Superintelligent Robot would continue to fight according to instructions, which was also a requirement given to them by the fleet.
However, the fleet had never experienced such a large-scale communication disruption without a backup plan. In the Milky Way, even if communications were collectively cut off, there would be backup plans, but not in Sextans. Hu Yu had not expected this situation to occur. The Superintelligent Robot possessed completely autonomous intelligence, and he had no idea what they would do.
Hu Yu had no choice but to let the Snow Tribe Clan continue sailing towards the outer reaches of the galaxy, while he led a small fleet to chase after the 5 trillion Conqueror of the three-dimensional universe. Gravitational waves were no longer usable, but electromagnetic waves were still functioning normally. He had already sent out a signal for the fleets to return. Hu Yu was worried, as there had been repeated unexpected events here. Only by personally chasing after them could he minimize the losses.
In fact, a change had already occurred. As soon as the fourth-dimensional fleet discovered that it had lost contact with Hu Yu, it immediately returned to base. When these Superintelligent Robot were preparing to descend into the three-dimensional universe, they found that space seemed to be isolated, and they were unable to descend into the three-dimensional space at all.
Fortunately, the Superintelligent Robot in the three-dimensional universe also sensed that something was wrong and returned to base immediately. They soon reunited with Hu Yu. Given the current situation, Hu Yu had no choice but to abandon the attack plan again. If he still couldn't see the danger at this point, he shouldn't continue leading the fleet.
The 5 trillion Conqueror activated their conventional engines to maximum power, accelerating Conqueror to 0.6 times the speed of light, and sailed at full speed toward the outer edge of Sextans.
From then on, the fleet encountered no further incidents, and Hu Yu felt slightly relieved. As for the fleet in the fourth dimension, Hu Yu planned to wait until he escaped the restricted area before entering the fourth dimension to search for it. Until one day, the Giant General Civilization suddenly discovered that its fleet could actually enter the fourth dimension.
This is a very strange thing. Warp drive and entering the fourth dimension can only be achieved through space distortion and energy changes. The fleet cannot perform warp drive in the three-dimensional universe, but it can easily enter the fourth dimension. Moreover, the method of entering the fourth dimension has become simple. As long as the warship increases its energy level, it will be automatically sucked into the fourth dimension. Apart from this, dimensional reduction attacks are not affected. The only thing affected is warp drive in three-dimensional space.
Not only could the fleets of the Giant General Civilization enter the fourth dimension and carry out dimensional reduction attacks, but the fleets of the other three Great Star Region Civilization could as well. However, this change did not appear in Hu Yu's fleet. Upon discovering this, the Giant General Civilization was overjoyed and immediately gathered trillions of warships to attack Hu Yu's fleet once again.
Although the Conqueror had been two-dimensionalized, Yan Xue's fleet had not. Hu Yu did not have enough two-dimensional space to two-dimensionalize Yan Xue's fleet. The Giant General Civilization easily tracked Hu Yu through this, but they did not discover that Hu Yu had three trillion Conqueror and one trillion Dreadnought in the fourth dimension.
The fourth-dimensional Superintelligent Robot, unable to enter three-dimensional space, have been accompanying Hu Yu on his slow journey, providing Hu Yu with protection. These fleets have also undergone two-dimensionalization; they appear like ghosts within the fleet of the Giant General Civilization and immediately launch two-dimensional bombs.
The anticipated explosion did not occur; the two-dimensional bombs disappeared as soon as they left the warship. However, countless two-dimensional bombs appeared in the airspace near Hu Yu, searching for targets in the air but finding nothing. When the allotted time expired, these two-dimensional bombs deactivated their two-dimensional state and exploded. This was a program set for two-dimensional combat; even if the attack missed, they would not exist for long to avoid being captured by the enemy.
Hu Yu quickly learned of the explosion of the two-dimensional bomb, but Hu Yu was unaware that the series of explosions near the fleet were his own two-dimensional bombs, and he had no idea that the Giant General Civilization had already been encountered by the Conqueror in the fourth dimension.
The first wave of attacks all missed, and the Superintelligent Robot had no choice but to dismantle the two-dimensional structure and launch a spatial attack. Suddenly, four trillion warships appeared. This time, the Giant General Civilization finally realized that these warships came from two dimensions. They immediately began to bombard the surrounding space. The ordinary combat power of the Conqueror was no stronger than that of the Giant General Civilization's warships.
After a battle, both sides suffered losses. Although the Conqueror had a slight advantage due to their Fifth Reversed State, the Giant General Civilization was, after all, Great Star Region Advanced Civilization. Coupled with their absolute numerical superiority, the Conqueror and the Dreadnought quickly fell into a disadvantageous position. The Superintelligent Robot did not continue to entangle with the Giant General Civilization. Their objective had been achieved. Hu Yu had learned about the war in the fourth dimension through the drastic spatial changes and the low-energy debris that kept appearing in the three-dimensional space.
The Giant General Civilization dispatched a portion of its warships to pursue the fleeing Conqueror and Dreadnought, while the remaining 8 billion warships descended into the three-dimensional universe, firmly surrounding Hu Yu and Yan Xue's fleet.
Hu Yu sensed the change in the situation when the two-dimensional bomb exploded, and had already transferred all of Yan Xue's people to the Conqueror. Although Yan Xue's fleet was not as powerful as the Conqueror', its numbers were severely insufficient, so Hu Yu chose to leave the fleet behind.
However, Hu Yu never expected that the fleet of the Giant General Civilization would descend from the fourth dimension. Countless warships directly descended into the Conqueror Fleet. Although they could not travel faster than light or attack, and all spatial attacks were ineffective, the dimensional reduction attack of the Giant General Civilization immediately plunged Hu Yu into a desperate situation.
Although the fleets of the Giant Warship Civilization could not detect the two-dimensional Conqueror, the sheer number of enemy fleets and the constant dimensional reduction attacks forced the Conqueror to reveal themselves. Moreover, the Giant General Civilization already knew that the invaders' fleets had undergone two-dimensional processing, making it difficult for the Conqueror to find opportunities for covert attacks.
Hu Yu had no choice but to use the two-dimensional fragments, hoping to use their dimensional reduction attack to strike the Giant General Civilization's fleet. However, after the two-dimensional fragments were launched, no dimensional reduction phenomenon appeared in the surrounding three-dimensional space. To be precise, there was no obvious dimensional reduction. The two-dimensional fragments only attacked a distance of less than a few hundred meters before dissipating. This distance was almost ineffective in interstellar warfare.
