It had been more than a week of Christmas vacation at Hogwarts, and Lynn had no intention of wasting that time. Early the next morning, Lynn found Professor Green, hoping to start his practical lessons early.
After hearing Lynn's idea, Professor Green was slightly surprised but immediately agreed, "No problem. However, my office can't accommodate a battle between us. Follow me."
With that, Professor Green led the way, leaving the Defense Against the Dark Arts professor's office.
Professor Green took Lynn out of Hogwarts Castle and walked toward the Forbidden Forest.
After walking for more than ten minutes, the scenery in front of Lynn suddenly opened up. What stood before Lynn was no longer a dense and endless forest, but a large open space with a radius of more than 100 meters!
"This is a place that Dumbledore and I specially reserved after submitting the request. Our future practical lessons will be held here. However, it's better that you don't come here alone without me guiding you, as there is an Acromantula tribe nearby."
Professor Green arrived at the center of the field and told Lynn.
Lynn nodded and followed him closely to the spot. He placed his wand over his chest, slightly bowed to Professor Green, and performed a dueling salute.
Before Lynn could straighten up, a red light shot toward Professor Green.
Lynn understood that the battle had already begun.
"Protego!"
Lynn quickly turned to the side to avoid the red light and instinctively cast the Shield Charm.
A gray-white light appeared in front of Lynn's left side, clashing with the Shield Charm, and finally, the Shield Charm was deflected.
That was close!
Lynn thought to himself, realizing how dangerous it was.
After witnessing the battle between Professor Green and Casiraghi on Halloween night, Lynn knew that Professor Green's movements would never be simple.
As expected, while Professor Green silently cast a Disarming Charm, he followed it up with a crushing spell!
If Lynn hadn't been attentive, he could have been tricked!
"Incendio!"
Lynn quickly cast the spell, and a fireball shot from his wand.
Although Lynn had been able to cast spells silently, the fire spell cast with an incantation was usually more powerful.
The flames continued to spread in the air, forming a force that burned the sky and boiled the sea over the area, heading straight toward Professor Green.
"Aguamenti!"
Professor Green waved his wand, and a stream of water shot from the sky, meeting the flames that filled the air.
The flames collided with the water flow, and countless steam clouds exploded, covering the entire battlefield.
Their vision was blocked by a thick white fog, and neither of them could see the other.
Lynn cast a Silencing Charm on himself to muffle the sound of his footsteps, then began to move, changing positions.
Lynn waved his wand and silently cast several Disarming Charms toward Professor Green's original position, but received no response.
Realizing this, Lynn understood that Professor Green must have used the same tactic as he had.
At that moment, a slicing curse flew through the air, narrowly missing Lynn's shoulder. Lynn was so startled that he sped up, running faster.
As he ran, Lynn quickly cast three more Disarming Charms. These were aimed at the direction of the slicing curse and to the left and right of that direction.
Lynn's prediction was correct. The Disarming Charm fired to the right was blocked by the Shield Charm, but it also revealed Professor Green's position.
Quickly, Lynn cast another spell, raised his left hand, and used wandless magic to cast a large fireball from his palm.
The flames quickly expanded, surrounding Professor Green from all sides, and the front of Professor Green was blocked by the countless spells Lynn had cast, preventing him from changing position before the flames surrounded him.
Lynn couldn't help but smile. In his mind, he had passed this practical training.
The battle between Lynn and Professor Green was only a lesson, so Professor Green did not use alchemy in the fight, and he also suppressed his own magical power to the same level as Lynn, giving Lynn the opportunity to corner him.
But just as Lynn thought he was certain of victory and was about to pop open the champagne, something unexpected happened!
In the blind spot of Lynn's vision, the stones on the ground suddenly swelled up. These stones suddenly transformed into more than a dozen pitons the size of a thigh, spinning toward Lynn at lightning speed.
These pitons quickly wrapped around Lynn's thighs, waist, arms, and neck, holding him firmly in place. The last piton lunged with agility, first flicking its tail and disarming Lynn, then firmly locking Lynn's left hand with its own body and interrupting his wandless fire spell.
Without the supply of magical power, the flames that were about to catch on Professor Green's clothes instantly lost control and were easily extinguished by Professor Green.
"In battle, enemies tend to focus on the magical spells coming from the front and ignore the effects of Transfiguration. If you can skillfully use Transfiguration abilities and combine them with real combat, it will definitely bring unexpected results!"
Professor Green stepped forward with a smile.
He waved his wand, and the pitons wrapped around Lynn's body suddenly lost their vitality and turned back into their original stone form.
Lynn couldn't help but smile bitterly. Was it because he didn't want to use it? He had received Professor McGonagall's Transfiguration notes just yesterday and hadn't even had time to read them yet!
"Continue," Professor Green said without saying more, simply returning to his original position.
Lynn stood up and returned to his original spot.
After greeting once again, Lynn took the initiative and cast a Disarming Charm.
Professor Green slightly turned to avoid the Disarming Charm, with his wand held behind his back.
Seeing this, Lynn suddenly had a bad feeling.
Without even looking, he raised his wand and cast a jet of flames, burning them behind him.
Sizzle…
Dozens of snakes made from branches were seen burning in the flames. These transformed snakes were also being controlled by Professor Green's Transfiguration technique.
"Annoying Transfiguration!"
Lynn cursed silently. He still couldn't use Transfiguration in battle, so he had no choice but to continually retreat when facing Professor Green's Transfiguration technique.
No doubt, with a less refined fighting style than his opponent, Lynn was once again defeated.
However, Professor Green had no intention of letting Lynn go, and the repeated "continue" made Lynn feel a bit desperate.
Since he couldn't escape, Lynn had no choice but to concentrate all his energy on fighting. He began to try mimicking Professor Green's casting methods, using Transfiguration to control the surrounding branches and stones and form effective attacks against Professor Green.
Under the high-pressure training from Professor Green, Lynn's Transfiguration skills were gradually improving.
