Chapter 753: Chapter 578: Underground Chamber_2

Deep underground, thousands of kilometers beneath the surface.

He Song quickly carved out a medium-sized secret chamber.

Since he was within Luo Feng Province's mansion, He Song couldn't build the secret chamber too large.

After all, if chaos erupted within Luo Feng Province's mansion, whether it was a Foundation Establishment True Person acting with a grudge, or a Golden Elixir Master wielding mana, it could cause immense destruction.

If the secret chamber were too large and were breached with a single strike, everything inside would be exposed for all to see.

He Song's efforts would then have been in vain.

To be cautious, it was better to construct a secret chamber of moderate size, big enough to accommodate oneself and one's various structures.

On normal days, He Song stayed within the mansion.

And when needed, he could take out the various buildings from his storage bag and place them in the secret chamber.
