The meeting room.
This was a massive structure, thirty meters high, and the tallest building in the entire academy except for the observation tower.
But even at thirty meters, it only had two floors. The first floor was classrooms, and the second floor was the meeting room.
At this moment, the entire meeting room was filled with people. A rough estimate put the number at no less than ten thousand.
They were all advance personnel from various major cities, primarily construction workers, engineers, formation masters, and geomancers responsible for building defensive fortifications.
The rest were elite soldiers drafted from the central city, tasked with protecting these construction personnel.
Lin Yu also arrived. He stood at the back, listening to a general speak from above.
"I'm a rough man. I've spent my entire life fighting. I've been to the Western border to fight the grassland barbarians, to the Northern border to fight the undead, and to the East Sea, where I battled sea beasts for ten years."
"I've traversed and fought across the entire human territory. How many heroes have shed their blood on the battlefield to protect our human lands."
"Today, another foreign realm wishes to invade our human race, to turn us into slaves, to turn us into domesticated livestock, into mere food."
"I cannot tolerate this. Can you?"
Before he finished speaking, many people were already breathing heavily.
Some raised their fists and shouted, "We cannot tolerate it!"
"Then what should we do?"
"Fight!"
"Fight!"
"Fight!"
The shouts of "Fight!" echoed in the air.
They were inspiring and blood-boiling!
Many people's eyes turned red, wishing they could unsheathe their swords and charge into the enemy's lair.
Even Lin Yu felt his blood surge.
The general said, "Then, as you wish!"
"Let's fight them!"
A crude curse brought him closer to the crowd.
At his command, everyone left the meeting room and headed towards Guixu.
Lin Yu was stopped by his senior disciple brother, who said,
"Don't listen to his nonsense. You shouldn't go. Our Guixu Academy is a transit point and the second line of defense. You should stay in the academy and guard it with me."
The Supreme Academy itself possessed a powerful formation. It was rumored to be able to withstand a blow from a divine being, though no one believed it. However, it should be able to defend against a ninth-tier expert.
"Our academy's formation was acquired by Master. As long as there are enough energy crystals, ninth-tier combatants will never be able to break through it. You'll be safest staying here!"
Lin Yu felt warmth in his heart.
However, if everyone else went to fight, would it be appropriate for him not to?
After thinking for a moment, he nodded, "Okay, I'll listen to Senior Disciple Brother."
Senior Disciple Brother said, "I know you want to fight on the front lines, but it's dangerous there. The defenses aren't ready yet. Once they are, I won't stop you from going."
"Also, Master told me that the enemy will arrive in three days at the latest, so don't go out during this time, understand?"
Lin Yu nodded repeatedly and said, "Yes, I understand."
Senior Disciple Brother left, his mission being to guard the academy.
Lin Yu, on the other hand, felt a bit idle.
He went back to the library, said a few words of encouragement to his clones, and then went to the quiet room to open Xiaojian's livestream to pass the time.
On the screen, Xiaojian had already arrived with the main force before the large mountain. Many people had started to move. After setting up various high-tech equipment, they began to transform the entire mountain.
This mountain wasn't very tall, but it was still thousands of meters high.
However, construction personnel of all kinds began to make gestures towards the mountain.
The viewers of the livestream didn't understand what they were doing. Xiaojian found someone and asked, and then understood.
"Dear viewers, I just asked."
"They are measuring the mountain body and the trend of the earth veins, and then transforming the entire mountain into a base to resist the invasion."
"Many people may not understand. Let me explain. Transforming a mountain is not a difficult task. If only technological means are used, it's naturally very difficult. But for formation masters, transforming a mountain is just basic operation."
"Look, they're starting."
Everyone watched as a man in a Taoist robe inserted formation flags at various points on the mountain.
Many people were outsiders to formations and didn't understand. Suddenly, they saw all the formation flags light up, forming a huge shield in the sky.
Then, the man shouted, "Tai Chi Four Spirits Formation, activate!"
Rumble!!!
In the sky, phantoms of the four sacred beasts appeared in the four directions, faintly guarding the four corners.
In the center of the formation, a Tai Chi diagram floated.
"Formation complete! Conceal!" He formed a hand seal and said softly.
As his voice fell, the formation concealed itself, and it seemed like nothing had changed. But everyone knew that the formation was complete. Once an invader arrived, activating the formation would be able to defend against powerful enemies.
Afterward, a discreet accompanying personnel placed boxes of energy crystals at the core nexus of the formation. This would be the energy to support the operation of the great formation.
Although energy could be absorbed from the air, it was too slow. It might take a year to absorb enough energy to activate for an hour, which was far less convenient than using energy crystals directly.
This method astonished the viewers.
Many people had never seen such a scene before. They cried out in surprise, as if they had never seen the world.
"Amazing! This move has astonished me. This is a formation master."
"That formation master, I think I've seen them somewhere before."
"What's next? The formation is set up, what are the others doing?"
"Don't be in such a hurry, just watch."
Xiaojian also quickly explained:
"Everyone, don't worry. From what I know, after the formation master sets up the defensive formation, geomancers will adjust the earth veins, and then architectural engineers, under the guidance of the formation masters and geomancers, will build structures to form the internal formation!"
"The so-called internal formation is the formation inside. Just watch!"
Lin Yu was also quite curious. He had started learning formations, but the formations he knew were very basic. A formation that could cover an entire mountain, even he was astonished.
As expected, geomancers took out their compasses and began to locate the earth veins. Their techniques were also extremely strange, and everyone couldn't understand them.
After the geomancers finished, the mountain seemed unchanged, but everyone looked at the mountain and felt that it had become more refined and beautiful.
The more they looked, the more pleasing it was to the eye.
"Why do I feel like this mountain has become prettier? Is it because I've been single for too long?"
"The above is correct. Me too. Are there any single girls in the comments section? DM me, I'll reply!"
"This is going off-topic. I'll explain. This is the geomancer's technique, like subtly adjusting a person's facial features. Even though it doesn't look like it's changed, it just looks better and more pleasing."
"Look quickly, the construction team is going up!"
The construction team was much simpler and cruder.
With the help of various machines and awakened individuals, their construction speed was astonishing.
The entire mountain, stretching for a hundred miles, was completed in one day.
Many people witnessed such a spectacular scene for the first time, their jaws dropped, amazed by the power of technology.
After all these preparations, they began to set up defensive measures, deploying all sorts of siege weapons and heavy weaponry.
Then, they just waited for the enemy to arrive.
They didn't have to wait long. The next morning, just as the sky began to whiten, movement appeared in the black vortex.
"Roar!"
They were here!
