The spirit blackholes floated in the air. Sound waves, light waves, particle waves… All sorts of energy waves weren’t able to spread. They were completely devoured silently by the spirit blackholes.

　　When the spirit blackholes appeared, they instantly started to devour their own kind. The spirit lifeforms on fire caused by the crimson refinement gunpowder were all devoured cleanly. Nothing was left of them.

　　The cannons of the Great Wall University fired unceasingly. Metallic cannon artillery shells arced through the air, but the spirit blackholes didn’t hesitate and swallowed everything.

　　Matter was a super stable structure that energy-lifeforms did not have.

　　Feng Lin understood that the spirit blackholes had highly concentrated energy-structures, to the point of forming semi-material states. This was why they could resist the destructive effects of the crimson refinement gunpowder in their stomachs.

　　For a time, all the crimson refinement gunpowder was completely devoured. This weapon that humans created to deal with the spirit race had now all lost its effectiveness. But this didn’t mean that the spirit blackholes didn’t need to pay a price.

　　The spirit blackholes could even devour red tides of flames, if they devoured too much, the quantity consumed would lead to a qualitative change!

　　During these few days, Feng Lin led the refinement chamber to produce over 1,500 kg worth of crimson refinement gunpowder. With such quantity, the amount of destruction they could cause to energy-lifeforms would definitely be extremely terrifying. Even for the spirit blackholes, it was impossible for them to endure it completely.

　　From the depths of the black hole-like bodies, a red light began to flash. The flames created slowly caused the temperature to rise within them.

　　Feng Lin narrowed his eyes. He instantly knew that the energy structures of the spirit blackholes were swiftly crumbling apart.

　　However, the spirit race was an alien race with intelligence not inferior to humanity. Just by blocking the might of the crimson refinement gunpowder, they had already achieved their purpose. They didn’t mind paying some price to accomplish their objectives.

　　Po~

　　A wormhole opened again, the spirit blackholes obeyed the rules of their race and entered. When they appeared again, they were already at a location extremely far away somewhere in space. All of a sudden, they exploded like a supernova. It was only a long time later did their light reach the location where the battlefield was.

　　They sacrificed over ten spirit blackholes and the spirit army finally managed to shift all the threat constituted by the crimson refinement gunpowder away. The crimson refinement gunpowder no longer had a way to threaten them.

　　The war instantly reverted to a state of balance; both sides kept continuing a war of attrition.

　　The sounds of cannons echoed through the air.

　　The situation of the star fortresses didn’t seem optimistic.

　　The spirit tides were boundlessly vast. All exits of the Great Wall University were locked down by the spirit race. There was no way for them to request reinforcements; thus, they could only participate in a war of attrition.

　　This was a showdown of strength against strength. There weren’t many tactics involved.

　　And in an interstellar war like this, weaponry of science and technology dominated the battlefield. Their power was such that strategies were completely useless.

　　Only when two sides were equal in strength would the military strategy be of use.

　　And this was why it reflected the intelligence of the previous generations of people in the Great Wall University.

　　The fortresses of the Great Wall University were built on fixed stars. The fortresses could draw on the energy of the star for their own use. Stars underwent high-intensity nuclear-fusions all the time; they were like gigantic atomic bombs with endless energy. It was enough to sustain the energy consumption of a fortress for a very long time.

　　All sorts of radiation energy clashed in the air. The flames of war blazed brilliantly as both sides bombarded each other for three days and nights.

　　And everyone inside the University was storing energy and waiting for the final battle.

　　At that final moment, everyone would rush out, fighting for their race.

　　(I will protect my own race!)

　　At this moment, everyone felt the same.

　　But fortunately, the star fortresses in the Great Wall University that were built by the senior generations were sturdy enough to withstand the artillery fire of three days and nights. The energy barrier was extremely well-fortified and didn’t crumble. Even after three days, humanity still had not fallen into a perilous situation with their defenses overrun.

　　And after failing to take down the Great Wall University for a long time, the spirit race couldn’t endure any longer. Or maybe, they were waiting for a mature opportunity, and their attacks changed for the first time.

　　BOOM!

　　Another giant wormhole was opened.

　　A mothership-like gigantic spirit lifeform suddenly floated over from the crowd of spirit monsters. It exhaled, and numerous mechanical machines formed from alloys appeared in all shapes and sizes. Octopus, tigers, elephants…These were all mechanical beasts

　　The spirit lifeforms then entered the bodies of the mechanical beasts, and the initially lifeless mechanical beasts all seemed to have gained a soul. They instantly became active; their eyes shone with a red light as they rushed over ferociously.

　　As an alien race with intelligence, the civilization of the spirit race was completely different from humans. Their civilization was more similar to the structure of a bee colony.

　　Their science and technology weren’t inferior to humans at all. They actually managed to forge a set of mechanical bodies for themselves.

　　The mechanical beasts continued to rush forever. They slammed their now physical bodies into the protective barrier, wanting to break it.

　　The energy from the protective barrier blasted into the mechanical beasts. It was unknown which alloy they were constructed from but they could withstand great temperatures. They endured the damage, managing to squeeze their way inside the protective barrier.

　　RUMBLE~

　　The cannons of the university instantly blasted forth.

　　The first wave of mechanical beasts that managed to breach the protective barrier was instantly crushed by the return fire.

　　However, the numbers of mechanical beasts were thousands upon thousands, and they came in unending waves. They didn’t fear death at all. They forcibly endured the cannon fire and directly rushed to the main camp within the star fortresses.

　　As the mechanical beasts formally invaded, the first phase of attacks had already passed. Now, everything would boil down to single-man battles.

　　The star fortresses were ready for this. Countless cultivators wearing micro-mecha armor rushed out like a swarm of bees, fighting against the mechanical beasts. The scene was simply chaotic.

　　Gunfire, fresh blood, flames…the cruel yet inspiring war continued. Countless cultivators rushed out to reinforce the first wave. They ignored their lives and deaths and simply sought to take as many mechanical beasts down with them as they could.

　　Within the Great Wall University, a solemn voice suddenly echoed, “From now onwards, a new mission shall be issued. Hunting the mechanical beasts and defend the Great Wall University. Killing an ordinary spirit mechanical beast will net you 1,000 contribution points. Killing a large-scale mechanical beast will net you 10,000 contribution points and killing gigantic-scale mechanical beasts will net you 100,000 contribution points!…”

　　During an interstellar war, the rewards given for missions were extremely abundant as well.

　　Under the attraction of such rich rewards, there would surely be those bold enough to give it a try.

　　Killing intent permeated the atmosphere everywhere.

　　“KILL, KILL, KILL! For the sake of our race!”

　　“Kill! We must take revenge for our father!”

　　…

　　The blood coursing through the veins of all humans ran hot. Countless young students of the university also equipped their micro-mecha armor and rushed onto the battlefield like heroic warriors.

　　Feng Lin also felt a burning excitement.

　　Although his military rank was already at the first lieutenant level and there was no need for him to personally enter the battlefield, he wasn’t willing to lose out to others.

　　His micro-mecha armor radiated energy waves as Feng Lin’s figure disappeared into the masses of chaotic battles all around here.
