In fact, Teacher Chen did not fully impart the Konoha Dragon God to him, because Might Guy couldn't utilize it previously, only partially trained in it.
But just as Might Guy was reminiscing, he suddenly managed to initially grasp the Konoha Dragon God from a few demonstrations by Teacher Chen.
Mokgetsu's Breath of Rock, Might Duy's Eight Gates, Teacher Chen's Konoha Dragon God, at this moment, Might Guy has fully unleashed his potential, exhibiting unprecedented strength.
As Might Guy's body continuously rotates at high speed, a green dragon swiftly forms, appearing before everyone's eyes.
"Konoha Dragon God, Might Guy has actually mastered this." Sarutobi Hiruzen looked in astonishment at the green dragon on the field.
The Konoha Dragon God is regarded as Teacher Chen's ultimate move, known as an extremely difficult Taijutsu; apart from Teacher Chen, no one else in Konoha could do it. Surprisingly, Might Guy mastered it after just a few months of learning from Teacher Chen.
Teacher Chen, called the strongest in Konoha, naturally has his reputable Taijutsu. Many Jonin on the field began to discuss it.
"This kid, I haven't finished teaching him, how could he use it?" Teacher Chen, sitting in a corner of the spectators' seats, was somewhat surprised too.
It can be said that the current Might Guy is entirely different in strength compared to before the Chunin Examination. In his current state, Might Guy could easily defeat his previous self.
"Impressive, Guy, so you still had a trump card hidden!" Obito decided to retract his previous evaluation of Might Guy; it wasn't rashness, but confidence.
BOOM!!
When the yellow electric light and the green dragon collided, the venue experienced a huge explosion, with continuous roars.
A large crater appeared with Kakashi and Might Guy at the center, surrounded either by Thunder Slash marks or strong and sharp cut marks.
Bam!
A white-haired figure rapidly retreated, crashing hard against the venue wall.
"So strong." Kakashi panted heavily, looking at the green dragon before him.
This was the first time his Lightning Flash lost in a frontal collision; the current Might Guy is terrifyingly strong. Kakashi felt that in this state, Might Guy alone could defeat Ishijima Hideyuki.
"Am I going to lose?" Kakashi sensed the state of his body.
Previously hit by Might Guy's Leaf Hand Blade, breaking a bone, and the failure in the recent clash further left him with extensive injuries.
Not only injuries, but his Chakra and stamina were also nearly depleted. Although he only used Lightning Flash and a Flash once, he also used Ninjutsu; the consumption of Purple Lightning was not small either.
Kakashi wiped the blood from the corner of his mouth, answering the question in his mind with action.
He shakily stood up again; as long as he could stand up, as long as he could wield the blade, he still had the possibility of winning.
He strongly wanted to enter that transparent world again; this was his only hope for a counterattack.
The Konoha Dragon God moved swiftly, not needing Kakashi to advance. Upon discovering Kakashi stood up again, the green dragon quickly charged to Kakashi's front.
At this last moment, Kakashi saw it. Just like a month ago, he saw it. He saw his body and Might Guy's body.
"So the Lightning Flash still has so many flaws." Kakashi, at this moment, optimized his Lightning Flash.
Now Kakashi had no more thoughts; his remaining strength didn't support having more ideas.
In his mind now was only the thought of wielding the blade. As long as he could swing that blade, there was still hope.
"Slash!"
The White Fang Short Blade, infused with Chakra, was again extended, transforming into a Lightning Release long sword.
No more flashy effects; Kakashi simply slashed at the charging green dragon.
BANG!!
Yellow blade light flashed, the sound of thunder exploded, dust danced in the air, and a long, scorched slash mark appeared on the field.
After this slash, the green dragon was no more. Only a green-clad figure stood amidst the grayness.
"My dear friend, you truly are remarkable." Might Guy gave Kakashi a thumbs-up, then spent all his strength and collapsed.
Thump!
Kakashi's White Fang Short Blade fell from his hand. He used his last strength to give Might Guy a thumbs-up, then collapsed as well.
"Hatake Kakashi wins!" Hiruko announced the first place in the Chunin Examination, Kakashi fell slightly later.
PS: Sorry, it's a little late as I wanted to finish it in one go. Usually, I take leave in advance if I'm not updating; if not updated, it means I'm working hard on a big one.
