章 330: Lurking

Xuan Yi landed steadily and sized up the huge palace in front of him.

Although it didn't look very big from the top, when he was actually standing in front of it, Xuan Yi still experienced his own insignificance.

Just this exposed corner of the underground palace stretched nearly a thousand miles.

Not to mention the size of the palace hidden under the ground.

To enter the underground palace, one had to pass through the huge city wall in front of it that was tens of thousands of feet tall.

The Dao aura flowed continuously on the wall, even after millions of years, it was still extremely sturdy.

However, the ten great Sects still had some ability.

It was not an easy thing to enter through this city wall.

At the bottom of the city wall, there was a hole.

It could allow three to five people to pass through.

It seemed that the ten great Sects had all entered.

Xuan Yi did not stop at all. He stepped forward.
