Five Grand Unity Golden Immortals arrived and immediately flew to Chu Yun's presence.
"Commander Chu Yun, we have been ordered by the Heavenly Dao to come and provide support."
Chu Yun nodded. "Good, very good. Now we have eight Grand Unity Golden Immortals. The Heavenly Dao is paying close attention to this place. May I know the names of the five fellow daoists?"
Following that, the five Grand Unity Golden Immortals introduced themselves. It turned out they were all rogue cultivators, having not formed their own factions or become rulers of star systems or domains. The five Grand Unity Golden Immortals were traveling together when they received the Heavenly Dao's decree midway.
With eight Grand Unity Golden Immortals, and eight Grand Unity level extraterrestrial creatures within the Grand Unity Golden Immortal formation, the high-end combat power was now matched. For now, there was no need to worry about the extraterrestrial creatures below the Golden Immortal level.
Chu Yun summoned everyone to the discussion hall.
Chu Yun asked, "Now that our high-end combat strength is on par with these extraterrestrial creatures, does anyone have a method to eliminate the extraterrestrial creatures within the Grand Unity Golden Immortal formation?"
At this moment, one of the Grand Unity Golden Immortals who had just arrived spoke, "Commander Chu Yun, when the Heavenly Dao issued our decree, it also instructed us to visit a Grand Unity Golden Immortal. That reclusive Grand Unity Golden Immortal taught us a combined attack technique. He also told us about this Grand Unity Golden Immortal formation and some information about these extraterrestrial creatures."
Subsequently, the five Grand Unity Golden Immortals shared a great deal of information.
The creatures from the extraterrestrial universe connected by that spatial channel could be called the Ku Hei creatures, and the name of their extraterrestrial universe was indeed Ku Hei Universe. The Ku Hei Universe was originally a normal universe. However, several hundred million years ago, the creatures of the Ku Hei Universe were contaminated by a certain substance. After tens of millions of years, all the creatures in the entire Ku Hei Universe were infected. Thus, these Ku Hei creatures all transformed into savage beings. The universe was also renamed Ku Hei. The Ku Hei Universe then began to continuously invade other universes.
Ten thousand years ago, a Grand Unity Golden Immortal level Ku Hei creature from the Ku Hei Universe found the entrance to the Immortal-Demon Great Universe and created a passage.
The rest, as they say, is history.
Su Han was shocked to hear this. There were Grand Unity Golden Immortal level beings in the Ku Hei Universe as well. He never expected these creatures to be contaminated by that substance. If that substance were to appear in the Immortal-Demon Great Universe, would the entire Immortal-Demon Great Universe also be destroyed?
After explaining the origin of the Ku Hei Universe, they moved on to the existence of the Grand Unity Golden Immortal formation.
This Grand Unity Golden Immortal formation could absorb surrounding spiritual energy to maintain itself automatically. Therefore, there was no need to worry about the Ku Hei creatures within depleting spiritual energy to destroy the formation. However, there was a prerequisite: the Ku Hei creatures below the Grand Unity Golden Immortal level. If a Grand Unity Golden Immortal level Ku Hei creature were to attack, it would definitely be able to destroy the Grand Unity Golden Immortal formation. Therefore, besides guarding against the Ku Hei creatures within the formation, they also had to guard against any Grand Unity Golden Immortal level Ku Hei creatures that might escape from the main spatial channel. Furthermore, this Grand Unity Golden Immortal formation had a very important function: it could suppress the number of Grand Unity Golden Immortal level Ku Hei creatures that passed through this spatial channel. Only ten Grand Unity Golden Immortal level Ku Hei creatures could pass through. If these ten were eliminated, no new Grand Unity Golden Immortal level Ku Hei creatures would pass through. Therefore, protecting this Grand Unity Golden Immortal formation was also crucial.
Finally, there was the combined attack technique. This technique was created by the Grand Unity Golden Immortal during his reclusive life in his earlier years. When used by Grand Unity Golden Immortals, it could enhance their attack power. If ten thousand Grand Unity Golden Immortals used it together, it could even reach the power of a Grand Unity Golden Immortal. Of course, the maximum number of participants for this combined attack technique was ten thousand.
Soon, the group formulated a plan to use the combined attack technique to eliminate the eight Grand Unity Golden Immortal level Ku Hei creatures within the Grand Unity Golden Immortal formation.
After obtaining this wealth of information, Su Han synchronized it with the others in the Dragon Country. Su Han also began to worry about what might happen at the main spatial channel.
Su Han summoned a few Earth Immortals from the Dragon Country and said, "You go to the main spatial channel to scout. If any Ku Hei creatures emerge from there, issue a warning immediately."
After accepting Su Han's orders, the Earth Immortals, led by Xiao Yan, departed.
To prevent Ku Hei creatures from the main spatial channel from crossing over, the Dragon Country began deploying a large force of spaceships in space.
Chu Yun was astonished by these things that could operate without needing a large amount of spiritual power.
While these preparations were underway, Su Han and the other seven Grand Unity Golden Immortals began their assault on the Ku Hei creatures within the Grand Unity Golden Immortal formation.
The eight of them did not perform the combined attack technique beside the Grand Unity Golden Immortal formation. Although it was impossible to see from the outside, it was possible that the inside could see the outside. If they initiated the attack nearby, it would be disadvantageous if the Ku Hei creatures saw it and evaded.
"Once this combined attack technique is activated, our attacks will be superimposed. At that time, everyone will pour their main spiritual power into this flying sword."
The combined attack technique was not centered on Chu Yun, but on the Grand Unity Golden Immortal most familiar with it.
"Combined attack technique activated!"
With those words, the flying sword magical artifact grew immensely and cleaved directly inward.
"Boom!"
A violent explosion resounded. The formation, arranged in black by the Ku Hei creatures inside, was directly shattered. The flying sword, its momentum unabated, then struck at one of the Grand Unity Golden Immortal level Ku Hei creatures within.
The other seven Grand Unity Golden Immortal level Ku Hei creatures rushed to block the flying sword together.
"Boom!"
"Bang!"
After a powerful collision, the flying sword was blocked.
Su Han and the other seven Grand Unity Golden Immortals, forming a formation, joined the fray behind the flying sword.
The eight of them directly attacked one of the Grand Unity Golden Immortal level Ku Hei creatures. It was better to break one finger than to injure ten; once one was eliminated, it would be easier to deal with the remaining Grand Unity Golden Immortal level Ku Hei creatures.
The other seven Grand Unity Golden Immortal level Ku Hei creatures immediately came to their support.
Sixteen Grand Unity Golden Immortal level beings fought and retreated.
Meanwhile, outside the Grand Unity Golden Immortal formation, the Heavenly Immortals, Earth Immortals, and Golden Immortals seized the opportunity when the Ku Hei creatures' formation was destroyed to attack the Ku Hei creatures inside from the outside. There were now hundreds of millions of Ku Hei creatures inside, and any attack launched would hit many of them.
