During their conversation, Shen Luo and the others arrived in front of a big gate in the seabed mountain wall.
The gate was inlaid with two exceptionally thick, cast bronze doors, on which zigzagged traces of more than a dozen charm patterns. At the bottom of the gate, about a foot high from the ground, an octagon-shaped groove was seen.
Yuan Yi casually took out a green token with a turtle shell pattern engraved from his bosom, and threw it upwards. The token flew into mid-air enveloped in green light, and perfectly fitted into the groove on the bronze door.
Immediately, a ray of light spread from the green token, lighting up all the charm patterns on the bronze giant door. With the continuous rumbling, the two extraordinarily thick doors began to open inwards.
Beyond the bronze door, a dazzling golden light shone that made it almost impossible for Shen Luo to look straight.
