"Watch closely, I will activate this cannon in a moment. Try to observe the projectile thates out and the forces acting on it," said the professor.


    "Alright, Ma''am."


    "Ready, Ma''am."


    The professor then gave the activation signal to the cannon.


    "Boom..."


    The cannonball quickly shot out from the muzzle, soaring upwards with great force and speed. The female professor then made a hand gesture, gathering something from the empty air and pushing it down.


    "Ah..."


    "We''re moving..."


    The students'' bodies were suddenly lifted upwards at high speed, moving at the same speed as the cannonball.


    "Wow... has time slowed down?"


    "Yes, it seems so, but our movements are still normal."


    All the students could see the slow motion of the cannonball, the wind being split by it, and the friction between the projectile and the air. They could observe all these details up close. Unlike watching a video, seeing it firsthand with their own eyes was truly amazing.


    "You see, initially the projectile has a force of 450,000 joules. When this 10 kg projectile is shot upwards, it will increasingly lose its initial force due to gravity and air resistance in a certain space," exined the middle-aged female professor.


    "Pay close attention to how much force the projectile loses every few meters."


    The middle-aged female professor continued to exin everything that happened to and was experienced by the cannonball as it was shot upwards. She kept exining until the highest point the projectile could reach, where its force eventually became zero.


    Even as the projectile fell, the middle-aged female professor kept exining with all her heart, ensuring that all the students understood what force, gravity, speed, etc., were.


    However, during her exnation, the environment suddenly shifted back to the ssroom setting. All the students were still seated in their ces. The previously dark ssroom was now bright again, and the round ball in the center had stopped spinning and dimmed.


    "Alright, thank you all for attending our first ss. See you next week," said the middle-aged female professor while packing up her equipment.


    "Thank you, Ma''am."


    "Thank you."


    Ema, who was in the middle of the ssroom seating area, stared sharply at Walter, very annoyed that he had caused all themotion earlier.


    "If only this idiot hadn''t acted up," said Ema, clenching her fists.


    "Princess, don''t think about it," said Evan, trying to calm her down beside her.


    Meanwhile, at the front, Nita had already finished packing up her things. Na was also ready.


    "Let''s go home," Nita said to Na, a bit hurriedly.


    "What? Going home already?" Na asked, surprised.


    "Yes, let''s not dy any longer..."


    They quickly passed through the rows of seats and walked out of the ssroom.


    All the other students were also packing up their things and getting ready to leave. Walter, who was currently reading a chat panel in front of him, was no exception.


    - (Hilman): How was your lecture, son?


    - (Walter): Pretty good... what''s up?


    - (Hilman): Come home immediately, the scouting team found a goblin ind of 3 km in size.


    Reading about the goblins his father mentioned, a wide smile appeared on Walter''s face.


    "Treasure again, I hope there''s a light gem," Walter said hopefully.

    After ss ended, Nita and Na immediately left the ssroom. They walked quickly down the crowded corridor. Every few moments, Nita and Na passed by groups of students who were about to enter the ss.


    The campus system at New Life University didn''t have long lecture hours, only about 2 hours. This was because the material taught was the main subject ording to their major. Besides, if one wanted to be a researcher, following a regr campus program was the wrong choice.


    Nita and Na walked down the ssroom corridor for a few minutes, then entered one of the open elevators.


    Inside the elevator, Nita observed Na, who was daydreaming with a nk stare.


    "What did you think of the professor''s exnation earlier, Nay?" Nita asked casually.


    "Hahaha... yeah, the exnation was good," Na replied with a thin smile. Her mind was still thinking about the material that had been exined earlier. She was still doubting herself, wondering why she couldn''t understand any of the material exined by the professor.


    "It''s okay, it''s normal for the first day of school," Nita said, trying to reassure Na.


    After passing through various campus areas for a while, they finally arrived at the parking lot. Na rummaged through her bag to find her car keys, while Nita looked around, trying to remember where they had parked their car that morning.


    "Ah, there it is," Nita said, pointing to their blue sedan parked in the corner of the lot. They hurried toward the car.


    From the appearance of Nita''s car, even someone who didn''t know about cars could tell it was very expensive. Its design was sleek with beautiful curves. Additionally, the car hovered 10 cm above the ground, with a bright blue light glowing from underneath.


    After opening the door, they both got into the car and fastened their seatbelts. Na took the driver''s seat while Nita sat next to her. Na started the engine, and the smooth sound of the engine was heard. They immediately drove out of the campus parking lot.


    The city streets were quite busy with heavy traffic. Na drove carefully, paying attention to every traffic light and vehicle around her.


    Meanwhile, Nita opened the window and felt the refreshing breeze.


    "Ah... so refreshing."


    "So beautiful..."


    Nita inhaled the fresh, pollution-free air with a peaceful expression.


    The futuristic city atmosphere, with technology at every corner, further enhanced the beauty of the City of Life. Flying cars and objects whizzed through the air, flying buses hovered calmly, and magnificent skyscrapers stood tall everywhere. Blue holograms were seen all around, providing information and entertainment to the city''s residents.


    "In less than a month, the city that my brother and I built has grown this big," Nita murmured as she looked at the buildings along the road.


    "What will it be like in a year?" Nita asked with great hope.


    "It will definitely be a hundred... no, a thousand times more advanced than its current state, Nit," said Na from the driver''s seat.


    "Yeah... I hope so."


    With that, Nita and Na navigated through the city to return to the main City Hall.
