It was the tenth day of training.
The system sounded another skill evolution notification.
"Ding! Congratulations, host. Uchiha Flame Formation has met the conditions for evolution." "Evolution successful. Uchiha Flame Formation has evolved into Uchiha Great Fire Flame Formation." Ability: Generates intensely hot air currents to disrupt the enemy's vision. The flames have a degree of adhesion and inflict sustained burns. Trigger: Exquisite control over Fire Release energy, combined with the absorption of powerful external flame energy, produces a stronger effect.
After testing it, Yechen discovered that this evolution of Uchiha Flame Formation had greatly increased both the flames' temperature and their area of effect.
His training did not end after Flame Formation evolved.
Impure World Reincarnation had also improved during this time, but it still had a long way to go before meeting the conditions for evolution.
A month later, to Yechen's surprise, his Mangekyō Sharingan evolved, reaching the Eternal Mangekyō Sharingan stage.
To his disappointment, however, evolving his Sharingan into the Eternal Mangekyō Sharingan brought no substantial improvement. Its ocular power had merely grown somewhat stronger, and it had not even activated a talent.
His Byakugan, meanwhile, remained at the four-turn stage, with no sign of a breakthrough.
This meant that the Eternal Mangekyō Sharingan was not a separate evolutionary tier of the Sharingan.
That was indeed the case. In reality, aside from increasing ocular power, the Eternal Mangekyō Sharingan merely eliminated the blindness caused by excessive use of the Mangekyō Sharingan.
But Yechen had no such concern. That was why, when he evolved the Eternal Mangekyō Sharingan, he felt little improvement beyond the increase in ocular power.
Time drifted by, and two months passed in the blink of an eye.
Yechen ended his secluded training.
