The Jade Of Four Souls

Kimura Kazuki entered the passage first with a cautious look on his face.

Even though he was quite confident that his own strength had reached the peak of perfection in Japan, Unto Shrine had a history of more than 1,000 years after all, and so did the suppressed Majin. 

The Majin was still able to break the seal even though it had been sealed for over 1,000 years. Even though the seal might have loosened on its own, after all these years of suppression, the Majin still had the ability to break the seal. Obviously the strength of the Majin was not to be underestimated, just that they had no idea which level was the Majin's strength at. 

After Kimura Kazuki entered the channel, he looked around before taking a step forward. Dust rose and engulfed the air, cobwebs were everywhere in the passageway. It was apparent that no one had entered this place for ages.
