Facing extraterrestrial beings in the Tribulation Stage, cultivators from Dragon Country and Chu Yun Planet employed large-scale encirclement tactics, unleashing their attacks upon the alien entities.
The initial wave of extraterrestrial creatures was swiftly annihilated under the barrage of attacks from Dragon Country's Tribulation Stage cultivators and those on Chu Yun Planet.
After their demise, many of the annihilated extraterrestrial beings left behind a significant amount of black matter that persisted on the land. This black substance rapidly caused all vegetation within a ten-kilometer radius to wither and die, transforming the area into a barren black expanse.
The black region continued to spread outwards.
Some Earth Immortals attempted to dispel this black matter using their spiritual energy. However, their efforts only managed to dissipate a small portion of it.
An Earth Immortal nearby remarked, "There's no need to waste spiritual energy. Save it for attacking those extraterrestrial beings."
Another Earth Immortal expressed concern, "Even if we kill all those extraterrestrial beings, this matter will still remain. If it keeps spreading, all the plants on Chu Yun Planet will die!"
This Earth Immortal, being a native of Chu Yun Planet, naturally wished to prevent its destruction.
"What should we do then? Our spiritual energy seems to have no effect on this black matter. Look, the impact is so minimal."
Amidst their worries, a grand formation suddenly materialized around the spatial portal, slowing the spread of the black matter. The formation was so immense that the present Earth Immortals felt like mere boats adrift on a vast ocean.
"This formation… it possesses the might of a Grand Unity! It's a formation laid down by a Grand Unity Golden Immortal!"
"Indeed, this is a formation established by a Grand Unity Golden Immortal."
The assembled immortals were astonished.
However, the formation did not fully suppress the black matter. Instead, it continued to expand, eventually encompassing an area of one hundred kilometers. Thus, the formation enclosed a radius of one hundred kilometers.
The surrounding immortals were puzzled. The black matter hadn't even spread to a hundred-kilometer radius, so why did the formation create such a vast perimeter?
Meanwhile, on a distant planet, far from the knowledge of the immortals on Chu Yun Planet, there also existed a spatial portal. However, the situation there was entirely different from Chu Yun Planet. Here, the extraterrestrial beings had already breached a thousand kilometers, and the black regions on the entire planet had stretched over a thousand kilometers.
Just as despair set in, the formations established by the Grand Unity Golden Immortals activated, compressing the thousand-kilometer black region back into a hundred-kilometer area.
These formations to suppress the black matter were deployed around all spatial portals leading to the outer universe, each restricting the black matter to a hundred-kilometer radius.
Beyond a thousand kilometers, there were even planets where the black matter had spread to a radius of ten thousand kilometers before being activated by the Grand Unity Golden Immortals' formations.
In fact, the situation on Chu Yun Planet was the most peculiar. The area affected by the black matter's spread was far less than what the Grand Unity Golden Immortals had anticipated.
At this moment, in a rainy space within the Immortal-Demon Great Universe, a Grand Unity Golden Immortal was engaged in cultivation of the highest order.
During his cultivation, this Grand Unity Golden Immortal opened his eyes and gazed into the distance, saying, "Hmm, I didn't expect that the extraterrestrial beings from this spatial portal would be so effectively controlled!"
Su Han observed the hundred-kilometer formation in the distance and remarked, "I didn't expect the powers above to designate this battlefield to be within a hundred kilometers. If even more powerful beings appear in the future, these hundred-kilometer formations will surely be destroyed."
Su Han surveyed his surroundings, "No wonder Fellow Daoist Chu Yun relocated all the ordinary people within this hundred-kilometer radius."
A hundred-kilometer radius covered an area of 31,400 square kilometers, an area equivalent to the total area of a city in the former Dragon Country.
Under the bombardment of Dragon Country's artillery, an increasing number of Tribulation Stage extraterrestrial beings emerged from the energy weapon fire.
Su Han ordered the main forces to eliminate the straggling Tribulation Stage extraterrestrial beings within the hundred-kilometer range.
The Tribulation Stage cultivators on Chu Yun Planet were also hunting these extraterrestrial beings.
At this time, the Earth Immortals and Heaven Immortals remained on the sidelines, not engaging the Tribulation Stage extraterrestrial beings in combat.
This was the case for Dragon Country, and it was also the case for Chu Yun Planet.
Dragon Country primarily had Earth Immortals, with only Chu Shi as a Heaven Immortal. Chu Shi stood before the ranks of Dragon Country's Earth Immortals.
The Heaven Immortals from Chu Yun Planet also approached Chu Shi, seeking to establish connections. Chu Shi engaged in friendly exchanges with them.
They did not attempt to connect with Su Han, as his cultivation realm was higher than theirs. They also noticed that even Chu Yun's three Golden Immortal subordinates did not attempt to connect with Su Han. They presumed this was because they were Chu Yun's subordinates that they did not approach Su Han.
Dragon Country's Earth Immortals were closely monitoring the battlefield.
Most of the fighting took place in the air, as they were all capable of flight.
In the sky, a Dragon Country cultivator at the Tribulation Stage was engaged in combat with an extraterrestrial being when suddenly, another extraterrestrial being nearby attacked him directly.
The Dragon Country Tribulation Stage cultivator, caught off guard, was struck and sent flying in another direction.
Several nearby extraterrestrial beings, as if communicating, focused their attacks on this individual.
After several blows, the Dragon Country Tribulation Stage cultivator was gravely wounded.
The surrounding extraterrestrial beings naturally seized the opportunity, extending their claws towards him.
The Dragon Country Tribulation Stage cultivator, seeing the claws, uttered, "Die!"
He intended to launch his final attack before his demise.
Suddenly, an Earth Immortal's attack struck, obliterating several of the surrounding Tribulation Stage extraterrestrial beings. Following that, the Earth Immortal used a gravitational pull to draw the Dragon Country Tribulation Stage cultivator over.
"Youngster at the Tribulation Stage, it is not yet your time to perish. Return and recuperate well!"
