On the day of the Chunin Ninja Exams, Lin Yan was still only a Genin apprentice in charge of maintaining the barrier around the spectator stands. But when Neji's Rotation swept across the arena, he was forced to witness the inevitable fate from the original story: Hinata's certain death and Neji's loss of control.
His chakra was not strong enough, and he did not know enough jutsu. Then he would use twelve barrier spikes to turn the battlefield into a trap; use Byakugan nodes to share their field of vision; and use retreat routes to fight for the lives of ordinary shinobi. From a twenty-meter defensive zone, to a hundred-eye warning network, to a border Great Wall linking the Five Great Shinobi Villages, every step Lin Yan took required him to trade injuries and his comrades' lives for answers. Yet after blocking the Akatsuki for the first time, he discovered that the enemy had not broken through the barrier at all. The one who had raised the alarm was actually a "Konoha Ninja" within the formation.
White Zetsu had already infiltrated the defensive line. The next person marked as an enemy, could it be one of them?
