Sure, here is the proofread and enhanced version:

Early in the morning, when Harry and his friends arrived at the designated place, they saw a Gryphon. These majestic creatures, part eagle and part lion, are known for their strength and ability to soar through the skies.
Harry and his friends' eyes shone like jewels. "Are we going to ride this?" Meru asked, astonished.
"Yes, the Philosopher's Academy is so wealthy that they can arrange a Gryphon for transport," Liam exclaimed.
"You all are here. Come and sit; we will take off," Aiden shouted, standing high on the Gryphon.
There was a room-like structure on the back of the lion-eagle beast.
"Inspect."
[Gryphon: Spiritual Sage Level 1 Wind Element, Master in Flight]
Harry gulped when he inspected it. It was his first time seeing a creature of a Spiritual Sage level. He was thrilled because his system showed the element it possessed.
If this beast is a Spiritual Sage, then what could Aiden's level be? Spiritual Sage experts could fly, but their speed and stamina are far lower compared to creatures that focus on flight abilities.
He entered the building. There were four rooms connected to each other with a garden-like core area.
The area shook for a second and then stabilized as if they were on the ground, but in reality, they were flying.
Harry could see birds flying outside the windows. A man was sitting outside, controlling their mount.
"He has a taming skill," Aiden said, noticing Harry's curious gazes.
Harry nodded but wanted to try something. So he said "inspect" in his mind.

That was it. There was nothing more about that man.
"What element does he have?" Harry asked Aiden.
"People usually try to keep their element hidden, but they can't survive without using it. That's why we can often guess what type of element they have but can't determine it exactly.
In the case of beast tamers, they typically have mind-related psychic affinities. They can somehow talk to beasts and make contracts with them.
Tamers provide many resources to make contracts. If the tamers don't keep their promises, the beasts flee. There are also cases where, if the beast is more powerful than the owner, it attacks the owner for not keeping it satisfied," Aiden explained.
After a pause, he continued, "There are also other elements that could make beasts submit, like binding elements."
'My soul contract is on another level. I can make a contract with beasts far more powerful than me, and if any of us don't fulfill our conditions, our lives will be in each other's hands,' Harry thought, a chill running through his body. What if he someday makes a contract and fails to complete the conditions?
"What element do you have?" Harry didn't dare to inspect Aiden, so he politely asked. But his politeness didn't succeed in melting Aiden's heart.
Aiden smiled at Harry's question and said, "You should rest; it will take some time for us to reach the academy."
Harry smiled bitterly and went to a room with his friends.
On the way, they picked up students from various cities. There were at most two students from each city. They skipped many cities and didn't pick any students. Harry didn't know if other instructors took them or if no one passed the exam.
They traveled for three days, picking students from several cities. Now there were 20 students mounted on the beast, including Harry.
With the speed the beast was traveling, Harry could tell they had already traveled several thousand kilometers.
He was confused because, according to what he knew, the earth shouldn't be this big. The only explanation was that the domain was far larger than he had anticipated.
Along the way, Harry tried to practice his soul cultivation, and with the help of books and notes, he reached soul cultivation level 4.
He also tried to understand the soul refinement technique, but it was a slow process. He could feel his energy condensing slowly.
When he used the black sword, he felt as if the sword was trying to push his cultivation, as if telling him that the user was not eligible to use it.
There was no movement from the creator of the system. He was still absorbing that white orb. The only difference was the white orb's size grew smaller, but it was a tiny difference.
Currently, they were entering a city full of skyscrapers, with almost 100 times more people compared to Liam's home city.
"This rich energy, no wonder everyone wants to live in a high-tier city. Here, anyone could become an elemental master with just several years of training, and that's without using any resources.
If a person gets different resources, it will take just months," Tyler whispered to his friends.
They all nodded in agreement, feeling the burst of energy in their bodies.
Then Harry saw a grand entrance gate, larger than any building in this city. "Skylight City" was carved on that gate. They were just words, but Harry felt as if he were looking into the abyss.
They entered the city but didn't stop. After crossing the city, they halted after crossing a mountain.
When they passed the mountain, Harry saw large black walls covering several hundred kilometers.
They landed and approached the majestic gates. Two guards stood outside, looking like ants. Harry could feel strong energy emanating from them. He didn't need to use his inspect skill to tell they were very powerful.
Aiden came forward. Both guards bowed in respect. "These are the new recruits; complete the procedure," Aiden commanded.
They looked at all the students as if sympathizing with them. Harry frowned when he saw the guards' faces.
'Is there something wrong with this academy? Why are they looking at us as if we are cute pigs and they are sympathizing before butchering us?' Harry thought.
All the other students were thinking the same, and some of them started planning how they would escape if there was something wrong.
The guards came with some uniforms and gave each student one. The uniform was simple and basic robes; the only difference was its material and the numbers marked on their chests. The number seemed to be part of the uniform and yet separate.
Harry nodded and accepted his new uniform. His number was 3250. Liam, Tyler, and Blake got the numbers 3251, 3252, and 3253, respectively.
When the guard was about to give the uniform to Meru, Aiden stopped him and said she was a special acquaintance. She didn't need it.
Harry and all the other students looked confused, even Meru herself.
"You will join the academy later, but we won't be able to bring out your full potential, so someone requested to take care of..." Before Aiden could complete his sentence, a beast landed, roaring in the sky, the sound surpassing all barriers of space.
"Calm down, Bonu," a sweet voice echoed in the area, and a lady patted the beast.
"Bonu? How could someone call this beast by such a name?" Tyler muttered. He said this because of how the beast looked.
It had a similar shape to a dragon, but the difference was that several bones were sticking out of it. It looked as if a demon had descended from hell.
