The main feature of the secret base created by Ji Ruo was the word 'secret'.
Not only could it not be destroyed by anyone except the creator, but it was also extremely secretive.
Unless Ji Ruo was willing, this secret base could not be discovered by anyone!
Otherwise, it wouldn't be called a secret base.
However, this secrecy was two-way. Outsiders could not know what was going on in the secret base, and the people in the secret base could not know what was going on outside without a reserved 'observation point'-not even by phone.
The reason was probably because the system teacher had considered that children might not have cell phones... Of course, it was just a possibility.
After all, even if children didn't have a phone, they would still have a Genius Phone Watch on them…
Sometimes, Ji Ruo even felt that his system might have come too late…
Cough, cough, back to the main topic.
