Chapter 515: Chapter 333: Secret Realm Upgrade, Changes in Army Spirit (4K)_2

```

"It seems that if a lord's power is too weak, they may not even be able to harvest resources from a secret realm... However, given the difficulty of obtaining and upgrading a secret realm, such a predicament seems unlikely."

Until now, he had only obtained one such realm.

Mu Yuan released a Thunder Glow from his fingertips, effortlessly killing the monster in front of him before flying off into the distance.

Earlier on, when the secret realm hadn't been upgraded, the outline of a dilapidated church...or at least a corner of it, was faintly visible.

Only a corner.

But now, the ruined church was fully visible to Mu Yuan.

He descended.

Inside the church were different kinds of monsters, humanoid creatures that resembled sludge.

'Sludge Monster - Desire Monk'

'Sludge Monster - Headless Nun'

'Sludge Monster - Red Robe Bishop'

The bishop too was composed of sludge, with an indistinct face, but he wore a striking red robe and held a staff in his hand.
